Description

Blood sugar test unit

The invention relates to a blood sugar test unit consisting of a Plastic housing with receptacles for a test strip, disinfectant and Cotton ball and a needle that can be inserted into a support recess.

For blood sugar control to be carried out by the diabetic himself the necessary parts such as test strips, needle, disinfectant are separated offered in larger units and possibly combined in one package. This means that the checks that may have to be carried out several times a day for the Diabetic a very laborious procedure, since each part is individually made from its sterile Packaging must be unpacked.

Furthermore, the respective large packaging must be carried for each part, so that especially the blood sugar control outside the house because of the large volume to be carried Cutlery is cumbersome and unwieldy.

In order to simplify the control, it is therefore known all the necessary Elements for a control application in a plastic housing accommodate. In this solution, the needle is firmly mounted in the plastic housing. However, the fixed assembly of the needle requires the finger to be pressed onto the Needle to get a drop of blood for the test. That slow push is on the one hand painful and on the other hand requires a certain self-conquest, to carry out this lancing process. To facilitate the procedure are therefore Devices known that have a needle holder and a spring to be tensioned perform the lancing process with high dynamics. These very complex and large-volume However, devices make it more difficult to control outside the home because of the size of the Device and the other additional elements can be carried in your clothes pockets is usually not possible.

The invention is based on the object of a small-volume blood sugar test unit to create in which a dynamic lancing process is possible.

According to the invention this is achieved in that the needle tip in the support trough arranged recessed and after releasing a lock in the support trough can be snapped in according to the required lancing depth.

In the case of the blood sugar test unit according to the invention, after removal the cover for holding the individual elements required for the test first the fingertip with a cotton ball soaked in disinfectant disinfected. Then the fingertip is placed on the support recess, and through Pressure surmounted a built-in lock.

Until the barrier is overcome, the tip of the needle is below the Support recess. After the lock is released, the needle tip snaps with high dynamics into the fingertip and scratches the skin so far that a drop of blood emerges. The drop of blood is wiped off onto the test strip. Based on the discoloration of the The blood sugar level can be determined with the test strip. One too The fingertip can be cleaned by placing another cotton ball in the housing.

The test unit thus contains all necessary for a control application Elements together on a small volume. This means that several units are also without carry more in clothes pockets. Due to the snap effect, a high, pain-relieving dynamic achieved during the lancing process.

According to one embodiment of the invention, this can hold the needle Part and the part of the plastic housing having the support trough in an articulated manner connected and locked in a position to each other in which the needle tip is recessed in the support trough and the distance between the two parts of the required penetration depth of the needle. This solution has to be overcome the lock with two fingers to generate a corresponding pressure. When solving the Latching, the pressure energy is suddenly converted into kinetic energy, so that the high, pain-reducing speed results for the lancing process.

According to a further embodiment of the invention, the needle can one articulated between wall parts of the housing via film hinges and bent carrier strips mounted, and at least one end face with the Wall part connected to the carrier strip may be designed to be resilient towards the outside. The bent one The carrier strip presses the resilient wall part when it is bent into its extended position outside, so that the carrier strip is held in tension by this wall part. If the stretched position is slightly overbended, the carrier strip snaps with the needle mounted on it bent at high speed into the opposite one Resting position. The difference in height compared to the original location determines the depth of the piercing the needle. To improve the snap effect, the carrier strip can through a another film hinge to be divided at its deepest point.

For better release of the lock can be on the underside of the carrier strip a hump to be placed with which the bent carrier strip over his Extended position can also be pushed in. The fingertip to be scratched is placed on the support recess placed while with your thumb by pressing on the hump of the carrier strip over its extended position is brought so that it snap into its opposite rest position can.

Exemplary embodiments of the invention are shown in the drawing.

The figures show: FIG. 1 a three-part unit connected via film hinges Embodiment of the test unit in the folded state. FIG. 2 shows the embodiment according to Figure 1 in the unfolded state, Figure 3, the needle holding and the Part with support recess in partial section and before the piercing process figure 4 the two parts according to FIG. 3 after the lancing process; FIG. 5 shows a further embodiment of the test unit, FIG. 6 shows a partial section showing the carrier strip with a needle the test unit according to FIG. 5, FIG. 7, the partial section according to FIG. 6 after the lancing process The embodiment of the test unit la according to Figures 1 to 4 consists of one three-part plastic housing connected to one another via film hinges 2. the Injection molding of the plastic housing and, if necessary, the assembly of the needle 3 as well equipping the receptacles 4 with the elements necessary for the control application like test strips 5, cotton ball soaked with disinfectant 6 and a dry one Cotton ball 7 takes place in the unfolded state of all three housing parts. About the Recordings 4 and possibly also via the support recess 8 is used to cover a Foil glued on. All three parts are then folded together, whereby the the part 9 carrying the needle 3 and the part 10 having the support trough 8 in one Are locked position to each other, in which the needle tip in the support recess is recessed and the compressible distance 11 between the two parts of the required lancing depth of needle 3 corresponds.

The two receptacles 4 for the cotton swabs are used to control blood sugar 6, 7 having housing part 12 unfolded and peeled off the cover film.

With the cotton ball 6 soaked in disinfectant, the Disinfected fingertip and then placed in the support recess 8. With your thumb and the applied finger is - as shown in Figure 4 - by a thin-walled Bead 13 formed lock between the two latched parts by corresponding Overcome pressure. The one built up by the lock Pressure is through Buckling of the bead 13 suddenly converted into kinetic energy during the lancing process creates the desired, pain-relieving dynamic. After the lancing process, the Drops of blood emerging from the fingertip are wiped off on the test strip 5 and the blood sugar level can be determined by the discoloration of the test strip. By Dab on the dry cotton ball 7 will clean the fingertip The embodiment according to FIGS. 5 to 7 is a non-collapsible one-piece Plastic housing 14 is provided. To generate the dynamics during the lancing process is the needle 3 mounted on a carrier strip 15, which is between two wall parts 16, 16 'of the housing is connected in an articulated manner via film hinges 17 on the end face. Of the Carrier strip is hosed down bent so that its length is greater than the distance between the two wall parts 16, 16 '. At least one wall part 16 ' is formed resiliently by two parallel slots 18, so that when bending of the carrier strip 15 in the extended position, the resilient wall part 16 'after can evade outside. If the carrier strip 15 is slightly over the extended position When bent outwards, this part of the wall creates a tension that creates a tension on the carrier strip pushes into the opposite deflection. The difference in height between the two Rest positions corresponds to the path of the needle tip, preferably only the difference in height of the needle tip from the extended position to the opposite deflection for the Lancing process is exploited, since only this part takes place dynamically. For improvement the dynamic is the carrier strip 15 at its deepest point by another Film hinge 17 'is articulated.

The bending of the carrier strip in the stretched position can be done by a humps 19 arranged on the underside of the carrier strip 15 are facilitated, which protrudes with part of its height so far into a recess 20, as for triggering the snap effect is required.
