One such blood analyzer is known from WO 03/070099 A1.

Of the present invention is based on the object, starting from a carrier of the aforementioned type with a plurality of lancing elements the provision, storage and use of lancing elements improve.

These Task becomes with a carrier of the type mentioned according to the invention solved, that for a respective lancing element is provided in each case a receiving sleeve, in the the lancing element is slidably received.

On this way, the receiving sleeve for Positioning, leadership and for the protection, in particular for the permanent arrangement and storage of the Lancing elements are used.

In an advantageous development limits a respective receiving sleeve inside an axially continuous, in particular cylindrical opening, in the associated Lancing element is added.

The opening points expediently a diameter of 2 to 7 mm, in particular of 2.5 to 5 mm, in particular from 3 to 4.5 mm. The receiving sleeve further has expediently an extension in the axial direction of 6 to 20 mm, in particular from 8 to 15 mm and more particularly from 8 to 14 mm.

Of Furthermore, it proves to be particularly advantageous if a respective Lancing element has a molded-on holding body, which is the lancing element at the same time in the receiving sleeve leads.

Of Furthermore, it proves to be particularly advantageous if a respective Lancing element has a preferably molded protective cap means. The cap means protects the free end of the lancing element, which in the skin surface of a User is pierceable, from contamination and in particular against germs. It can even sterilize during an injection process of the lancing element in the region of the pierceable tip to effect and while to maintain the storage of lancing element.

To Another idea of the invention of self-importance shut that up Protective cap means the receiving sleeve to the stabbing side, it forms in particular a germ-proof conclusion the interior of the receiving sleeve.

The Protective cap means may also advantageously be elastic comprise deformable, in particular elastomeric area or out an elastically deformable, in particular elastomeric material be formed.

Of Furthermore, it may prove advantageous if the protective cap means in one piece over one Breaking range goes into the holding body. It can thereby the lancing element fully circumferential and in particular germ-tight enclose and preferably permanently effect a sterile closure.

The protective cap means advantageously has a diameter perpendicular to the axial direction of the receiving sleeve of 2 to 7 mm, in particular from 2.5 to 5 mm, in particular from 3 to 4.5 mm.

To Another idea of the invention, in turn, becomes independent in its own right proposed that a respective receiving sleeve for a lancing element at the same time includes or holds a test agent. In such case, the test agent is preferably in the range of a free one End of the receiving sleeve intended. The test agent may, for example in the form of a Measuring field defining membrane to be formed with an off taken from the body surface Minimum amount of blood is wettable. The test agent includes test reagents, by means of which an analysis or examination of the blood is carried out. The analysis or investigation, d. H. the evaluation of the test agent or the reaction in the test agent may be, for example, optically, in particular reflectometrically, or be performed electro-chemically or electro-physically. Evaluation facilities and evaluation methods as well as testing means of here usable type are known and therefore need no further description.

One such test agent may advantageously be pad-shaped or tablet-shaped be and held in the region of the wall or in an opening in the wall of the receiving sleeve be.

advantageously, the protective cap means is designed and arranged such that the Test agent before execution of a lancing process by the protective cap means is. As a result, the test agent on his to be examined from Blood-prone side from the ingress of dirt and moisture, preferably against penetration of germs and furthermore preferably be sterile covered or completed.

In Another embodiment of the invention is the protective cap against an axial stop of the receiving sleeve can be applied. In this way can a defined position of the protective cap means and thus in particular also the associated lancing element within the receiving sleeve and with that the carrier be specified. The receiving sleeve can do this a stepped opening with a step that forms the stopper for the protective cap means. It would be but also conceivable that the protective cap means in turn with a stepped outer circumference and / or a centering means in the broadest sense, the can be applied against the axial end of the receiving sleeve.

to Another preferred embodiment of the lancing element proves it as advantageous if the lancing element at least one resilient, in particular in one piece formed with the holding body Return means that has a return movement the piercing element according to the embodiment the lancing relative to the receiving sleeve causes or at least supported. Such a return means could for example in the form of a resilient arm, which is connected to the piercing element, preferably on the holding body molded or in one piece is formed with this, be realized. Preferably several, in particular three resilient return means provided. These Return funds can be found in advantageously before the execution a lancing also for stabilizing the lancing element within the receiving sleeve be used. In particular, you can they bias the lancing element in an axial direction, so that it is forced against a predetermined end position with respect to the receiving sleeve becomes.

In Further training of this inventive concept, it turns out to be particularly advantageous that a bias of the return means in the initial state of the lancing element the protective cap means in plant to the receiving sleeve, in particular in contact with the above-mentioned axial stop the receiving sleeve stops and thus leads to an improved, preferably germ-tight completion of the receiving sleeve.

The mentioned Return means may in this case against or on a portion of the receiving sleeve, in particular a ring-shaped Support axial end portion of the receiving sleeve, or it may be against a surface of the carrier support.

According to a further advantageous concept of the invention, a respective receiving sleeve can be inserted into a recess or another holder on the carrier. This has the advantage that the respective piercing elements can be manufactured separately and can be arranged in separate production or assembly processes in the interior of a respective receiving sleeve. The equipping of the carrier with receiving elements containing lancing elements for further use in lancing devices or blood analysis devices of the type mentioned, can then be carried out at a later time and in particular detached from the production of lancing elements and receiving sleeves. Although preference is given to a manufacturer-side assembly. However, it would also be conceivable in principle that one and the same carrier is used repeatedly by the end user and for this purpose each is equipped with new unused receptacles with lancing elements. Furthermore, it proves to be particularly advantageous if a respective receiving sleeve is held in an open-edged recess of a particular disc-shaped part of the carrier. This creates the possibility that a respective receiving sleeve protrudes in the radial direction over an outer peripheral surface of a portion of the carrier and there optionally with white can cooperate direct actuating means of a lancing device or a blood analyzer.

It also proves to be advantageous if a respective receiving sleeve displaceable on the carrier is held, in particular displaceable in the axial or radial direction is held. In this way, a receiving sleeve for carrying out a lancing process be moved to an exposed lancing position and after execution of the If necessary, lancing again in their starting position or moved back another position become. It should be mentioned at this point that the receptacles and Respective lancing elements with respect a rotatable, so rotationally driven carrier both axially as well as radially, ie with an axially extending piercing direction or arranged with a radially extending piercing direction of the lancing elements can be.

To A further advantageous embodiment is a respective one receiving sleeve during a rotation of the carrier Slidable by sliding against a forced guidance means. For example, the forced guidance means be arranged in a lancing device or a blood analyzer, that in the displacement of a respective lancing element with receiving sleeve in his Working position the receiving sleeve, as mentioned above, against a housing fixed Positive guide means slips on and it come to the above-mentioned displacement of the receiving sleeve can.

insofar it proves to be advantageous if a respective receiving sleeve at least has a resilient return means, the one return movement the receiving sleeve, especially after the execution causes a lancing relative to the carrier or at least supported.

To Another idea of the invention of particular importance is the respective receiving sleeve together with the lancing element received therein only in a preferred orientation on the carrier arranged. Such a measure proves to be particularly advantageous if the receiving sleeve at the same time the test agent stops or carries. such Falls can then namely be ensured that the test agent in a predetermined Orientation to the carrier and thus in a predetermined orientation to one in one Blood analyzer available Evaluation device of the type mentioned is positionable.

The receiving sleeve can have a non-circular, so deviating from the circular shape outer circumference. With appropriate design of a recess or other any bracket for the receiving sleeve on the carrier can be achieved that the receiving sleeve only in a predetermined Orientation on the carrier can be arranged.

Of Furthermore, it proves to be advantageous if the lancing elements have a gripping end portion, with which they to a Drive device within a lancing device or within a blood analyzer for execution of the lancing process can be coupled. This coupling is preferred brought about by the engage-behind end portions of the piercing elements Displacement, in particular rotation of the carrier, in a rear grip position or coupling position with a suitably trained organ get the drive device and by further relocation, in particular Continue rotation of the carrier after execution a lancing except Intervention brought with said organ of the drive means become.

A total with the reference numeral 2 designated blood analyzer is from the 1 to 3 seen. It comprises a housing body 4 with a display device 6 for displaying the result of the analysis or examination of a minimum amount of blood. The blood analyzer 2 but also includes an integrated total with the reference numeral 8th designated blood sampling device with a plurality of lancing elements 10 The one interacts with a lancing position 12 Applied skin surface of a user can penetrate quickly and painless as possible to gain a minimum amount of blood. Blood leaking from the skin surface wets a test agent 14 in which an analysis or test reaction takes place, which can be evaluated by means of an evaluation device, not shown. The evaluation device, which is not shown, may be an evaluation device which has an optical or electrochemical or electro-physical effect and by means of which a test or analytical reaction which takes place in the test medium can be detected and evaluated, which is known per se and therefore will not be described in detail at this point. The evaluation device can with the test agent in the illustrated lancing position 12 or in another position within the blood analyzer 2 interact. For example, it would be conceivable that from the 2 and 3 apparent test agents 14 by a rotation of a carrier to be described later 16 for lancing elements 10 and test agents 14 placed in a different position where the test agent 14 can interact directly with the evaluation device, not shown.

When starting up the blood sampling device 8th becomes inside the case body 4 and thus also in the area of the lancing position 12 generates a negative pressure. For this purpose, a negative pressure generating device 18 provided that a volume changeable area 20 includes, that of a bellows 22 is limited.

The negative pressure generating device 18 is by finger pressure on a pusher 24 actuated. In the course of depressing the pusher 24 Air is released from the volume changeable area 20 and the housing body 4 displaced to the outside. The subsequent reopening is under the action of a first spring 26 inside the volume changeable area 20 and thus inside the case body 4 generates a negative pressure. The first time you press the trigger 24 is at the same time about a still to be described in detail transmission device 28 generates a rotational movement on the wearer 16 for a plurality of at least 4, in particular of at least 6, in particular of at least 8, in particular of at least 10, and more particularly of at least 12 lancing elements 10 and a corresponding number of test agents 14 is transferred to a new unused lancing element 10 and associated test agent 14 in the lancing position 12 assigned work item 30 bring to.

Furthermore, the first time you press the trigger 24 about a coupling device to be described later 32 with a Bowden cable 34 a drive mechanism 36 the blood collection device 8th curious; excited. At the low Press the pusher 24 becomes the Bowden cable 34 under the action of a third spring 38 in the direction of the arrow 40 emotional. As a result, one of the Bowden cable 34 to the side projecting driving lever 42 taking a clamping device 44 for a pull wire of the drive mechanism 36 the blood collection device 8th in the direction of the arrow 46 relocated. The driving lever 42 can with a tangible end 48 in a locking device 50 be set in the tensioned state. When releasing the locking device 50 the clamping device releases 44 for the puller wire and the puller wire jumps under the action closer to be described spring means in the direction of the working position 30 and drives a lancing element arranged there 10 to execute the lancing process.

The one in the area of the lancing position 12 prevailing negative pressure assists in obtaining a minimal amount of blood from the skin surface and further assists in transporting the minimal amount of blood to the test agent 14 , By pressing the button again 24 becomes the lancing element just used 10 from his working position 30 together with the test agent 14 spent, and the test agent 14 is brought into a working position for the interaction with the evaluation device, not shown, where then optically, electro-physically or electro-chemically, the evaluation of the test reaction of the blood with the test agent 14 he follows.

The following is in conjunction with the 4a . 4b and 3 the transmission device 28 explained to implement an axial actuating movement in a rotary motion. The transmission device 28 includes a housing-fixed guide bushing 52 in which a pressure piece 54 through a stepped stop 55 is limited shiftable. At the free end of the pressure piece 54 is the pusher 24 pressed. In the other end of the fixed guide bush 52 engages a shaft section 56 with a spur toothing 58 a, which spur toothing 58 with a facing spur toothing 60 of the pressure piece 54 interacts. About a second spring 62 is the shaft section 56 in the direction of the pressure piece 54 biased. The shaft section 56 comprises on its outer surface a plurality of radially outwardly projecting and longitudinally extending webs 64 , which are in longitudinal grooves 66 inside the fixed guide bush 52 engage and prevent rotation of the shaft section 56 opposite the guide bush 52 while maintaining an axial displaceability effect. When depressing the pusher 24 becomes the pressure piece 54 moved axially, wherein the spur toothing 60 with the spur toothing 58 of the shaft section 56 cooperates and thereby generates a rotational driving force. However, a rotational movement is achieved by engagement of the webs 64 in the longitudinal grooves 66 prevents so that the shaft section 56 against the action of the second spring 62 also axially and in the representation of 3 is moved down. Once the jetties 64 from the longitudinal grooves 66 come free, one of the spur gear corresponding incremental rotational movement of the shaft portion 56 generated by a positive engagement of the spur toothing 58 and 60 is ended in one another.

The aforementioned rotary motion of the shaft section 26 gets on a gear pair 70 . 72 transferred, of which the latter on a hub section 74 of the carrier 16 is arranged rotationally fixed.

The transmission device described above 28 is designed as a rotary unit such that in the described first operation of the pusher 24 an axial lifting movement and a rotary movement of 360 ° / 12/2 = 15 °. Here is a new unused lancing element 10 in his working position 30 brought.

Under the action of the tensioned second spring 62 and the first spring 26 becomes the shaft section 56 and the pressure piece 54 contrary to the previous movement (in the 3 moved up). The return stroke of the pressure piece 54 is by the axial step stop 55 inside the guide bush 52 limited.

The following is based on the 5a . 5b and 3 the function of the drive mechanism 36 the blood collection device 8th described. The drive mechanism 36 includes starting from the lancing element 10 a form-fitting with a grasping behind the head section 76 of the lancing element 10 releasably connectable impact member 78 , The shock organ 78 is about a fifth spring 80 against a housing-fixed wall section 82 biased in the direction of impact. It includes an axial opening 84 through which a semi-rigid pull wire 86 in a cylindrical cavity 88 of the shock organ 78 hineinerstreckt and there by means of a sixth spring 90 is biased in the direction of impact. The semi-rigid pull wire 86 extends through an opening in the wall portion 82 through and through a clamping device 44 , consisting of a clamping cone 92 and a clamping device 94 through and through an opening in the driving lever 42 therethrough. In the released state of the clamping device 94 is the clamping cone 92 opposite the pull wire 86 movable. He is opposite the driving lever 42 so axially limited movable that when adjusting the driving lever 42 its inertia or frictional forces between clamping cone 92 and a surrounding cylinder wall clamping or release of the pull wire 86 in the clamping device 94 cause.

Is based on the in 5b Darge set position of the pushers 24 ( 3 ) pressed down, so is the driving lever 42 under the action of the third spring 38 pushed up. By the entrainment of the clamping cone 92 becomes the pull wire 86 in the clamping device 94 clamped and together with the driving lever 42 upwards in the direction of the locking device 50 emotional. In the locking device 50 becomes the tangible end 48 of the driving lever 42 fixed. The clamping operation described above takes place counter to the spring force of the fifth spring 80 which are the for the drive mechanism 36 stores the required impact energy. Will the locking device 50 by pressing a trigger 96 solved, so the tangible end 48 of the driving lever 42 released, so the inertia of the clamping cone leads 92 to that the clamping device 94 the pull wire 86 releases. The shock organ 78 and with him the pull wire 86 then fast under the action of the fifth spring 80 downward. Due to the coupling of impactor 78 and lancing element 10 guides the lancing element 10 then a lancing off. It jumps over the free end of a receiving sleeve to be described later 98 and is withdrawn behind the free end again.

Based on 6a to 6d is the training and arrangement of lancing elements 10 described. A respective lancing element 10 , which is a metallic needle-shaped element of a length of 6 - 15 mm, has a molded-on holding body 100 as well as a likewise molded-on protective cap means 102 on which the lancing element 10 protects against contamination and ensures a preferably germ-proof, preferably sterile closure against the environment. A respective lancing element 10 with holding body 100 and protective cap means 102 is in an already mentioned receiving sleeve 98 slidably received in the axial direction. The lancing element 10 is doing with his tangible head section 76 into the opening at the free end 104 the receiving sleeve 98 inserted and through the receiving sleeve 98 passed through until the cap means 102 to an axial step 106 inside the preferably cylindrical opening 107 the receiving sleeve 98 strikes. Recognizable in the figures is further a resilient return means 108 whose springy arms 110 , which are integral to the holding body 100 can be formed on an annular collar-like section 112 the receiving sleeve 98 rest. When performing a lancing process, these return means cause 108 in that the lancing element 10 again behind the end 104 the receiving sleeve 98 is withdrawn. The bias of the return means 108 in the initial state of the lancing element 10 Can also be used to protect the cap 102 in contact with the receiving sleeve 98 , in particular in contact with the axial stop 106 the receiving sleeve 98 to keep and so an improved, preferably germ-tight completion of the receiving sleeve 98 to effect.

The 7a to 7d illustrate how the head section 76 in particular in one piece with the molded-on holding body 100 may be formed in a tangible groove 114 of the shock organ 78 positively gripped or engaged behind. The shock organ 78 acts with a molded-on ramp means 116 together, which is also an off 7b apparent insertion opening 118 for the head section 76 of the lancing element 10 forms. This ramp means 116 acts with a run-on slope 120 attached to the annular collar section 112 the receiving sleeve 98 is trained. When the receiving sleeve 98 with the lancing element received therein 10 on the carrier 16 is moved in the circumferential direction, so slides the run-on slope 120 against the ramp means 116 on, and the entire receiving sleeve 98 is doing in the direction of the arrow 122 moved axially. Due to the positive engagement of the head section 76 of the lancing element 10 in the groove 114 of the shock organ 78 the lancing element is held in its original axial position, so that it moves axially in the direction of the arrow 122 not with executes. The lancing element 110 So it is relative to the receiving sleeve 98 withdrawn. This has the consequence that the protective cap means 102 from the free end of the lancing element 10 is released. It can fall down. The blood sampling device 8th is then ready to perform a lancing process. If the cap means 102 is removed, so there is also the test agent 14 free, which advantageously in the area of the free end 104 the receiving sleeve 98 is included. As in 6a hinted, the test agent can 14 in an opening in the wall of the receiving sleeve 98 be provided. The test agent is in the illustrated case inside through the cap means 102 covered and protected in this way from contamination, especially against access of humidity and germs, which is considered to be particularly advantageous. The cap mean 102 thus performs a dual function, it serves both the cover of the lancing element 10 as well as the coverage and protection of the test agent 14 ,

One recognizes in the 6 and 7 furthermore helically extending webs on the outer circumference of the receiving sleeve 98 , This is springback 124 , which at its upper end to the annular collar-shaped section 112 are formed. If the carrier 16 is continued and thus the just considered receiving sleeve 98 from her working position 30 and thus out of the influence of the ramp means 116 brought, lead this spring-back means 124 to that the receiving sleeve 98 again against the arrow 122 is withdrawn.

The 8a to 8c show in different views the carrier 16 for the majority of lancing elements 10 and test agents 14 , In the case shown, twelve receiving sleeves 98 with twelve lancing elements 10 and twelve test agents 14 added. A respective receiving sleeve 98 is in an open-edged recess 126 a disk-shaped part 128 of the carrier 16 used in the axial direction. So that the receiving sleeves 98 in their working position 30 when interacting with the ramp means 116 can not twist, are the open-edged recesses 126 and the outer circumference of the receiving sleeves 98 out of round, slightly elliptical in the illustrated case. This brings the further significant advantage that a respective receiving sleeve 98 in a preferential orientation on the carrier 16 is held, with regard to the positioning of the in the receiving sleeve 98 recorded test agent 14 is very important, because it must be able to interact at a predetermined location and orientation with the evaluation. The carrier 16 with a centrally arranged polygonal opening 130 for the engagement of a correspondingly formed hub portion 74 to the rotary drive of the carrier is together with the lancing elements 10 and test agents 14 in the housing body 4 can be used of the blood analyzer according to the invention and removed again from the housing body together with the used lancing elements and testing means. This is off 2 it can be seen where a cover which releases or closes the insertion opening is provided.

The 9 - 11 show a further embodiment of a blood analyzer according to the invention, in which the piercing direction and the piercing elements themselves are radially arranged with respect to a rotatably driven carrier for the lancing elements. Radially within the carrier, a drive device, not shown, is provided for the lancing elements.

The operation and function of the blood analyzer according to the invention in carrying out a blood collection and analysis is described below:
Starting from the in 3 shown basic position becomes the pusher 24 against the tension of the first spring 26 and the second spring 62 depressed a first time. During a first stroke section thereby the pressure piece 54 and the shaft section 56 axially displaced downwards. It creates a force in the circumferential direction. Meanwhile, the building move 34 the driving lever 42 free, under pressure of the third spring 38 in the direction of the arrow 40 emotional. At the same time the pull wire 86 in the clamping device 94 clamped and thus the pull wire 86 also pulled up. Meanwhile, however, the impact remains 78 another one of his starting position.

Finally come in a further Hubabschnitt the webs 64 from the longitudinal grooves 66 the fixed guide bush 52 free and the shaft section can make a rotational movement of 15 °. At the same time, the carrier becomes over the gear pair 70 . 72 moved by 15 ° and brings a lancing element 10 in the working position 30 , The head section slides 76 of the lancing element 10 in the opening 114 of the shock organ 78 and thus in the rear grip position. Almost at the same time the receiving sleeve slides 98 with its run-on slope 120 against the ramp means 116 and will be in the direction of the arrow 122 moved down so that the protective cap means 102 from the lancing element 10 is released. During the last part of the stroke movement of the pusher 24 is the free path of the pull wire 86 inside the cylindrical opening 107 of the shock organ 78 used up and the pull wire clamps against the force of the fifth spring 80 as main shock spring the drive mechanism 36 the blood collection device 8th , At the end of the tensioning movement becomes the tangible end 48 of the driving lever 42 in the locking device 50 fixed.

The negative pressure generating device 18 is now activated, and the drive mechanism 36 the blood collection device 8th is curious. By pressing the shutter button 96 can the locking device 50 be solved and thus the impact organ fast 78 under the force of the fifth spring 80 down and the lancing process is performed. Meanwhile, taking place under the force of the first spring 26 and the second spring 62 a reset of the pusher 24 instead of. In this way, the volume variable range 20 enlarged and it creates a negative pressure, which extends to the lancing position 12 in the area of the free end 104 the receiving sleeve 98 spreads and promotes blood collection and promotes.

Immediately after the triggering of the lancing, press the fourth spring and the sixth spring 90 the shock organ 78 back to its original position and thus cause the return movement of the lancing element 10 which also by the springback means 124 is supported.

Meanwhile, the shaft section becomes 56 under the action of the first and second springs 26 . 62 back into the fixed guide bush 52 retracted.

By pressing the button again 24 becomes the lancing element just considered 10 along with its receiving sleeve 98 and the test agent 14 then rotated by another 15 °; So it will be off the working position 30 the lancing elements removed. By a suitable design of the transmission device 28 is in this second operation of Stroke of the pusher 24 limited so that it does not cause a tensioning of the drive device 36 comes. The test agent 14 can thus be transported to an optical, electro-chemical or electro-physical acting not shown evaluation. Due to the predetermined positioning of the receiving sleeves 98 on the carrier 16 it is ensured that the test means are arranged in the correct orientation to the evaluation device.

It would also be conceivable that the second rotation by 15 °, which brings the lancing element from the working position, not by a renewed actuation of the pusher 24 but alternatively by the return movement of the shaft section 56 is reached. For this purpose, a run-on slope 132 at the free end of the footbridges 64 on the outer circumference of the shaft section 56 be provided. Upon reentry of the shaft section 56 in the guide bush 52 could be due to the interaction of these run-on slopes 132 with the longitudinal grooves 66 a further rotation of the shaft section 56 to be triggered by another 15.

The result of the evaluation is then, for example, in the form of the current blood sugar content on the display device 6 of the blood analyzer 2 displayed.
