Description
- The present invention relates to a device for transferring and dosing biomedical fluids between hospital containers.
- With particular reference to the oncology sector, but not only, it is known that to carry out numerous types of therapeutic treatments, the patients are connected to a parenteral infusion line placed in communication with a series of bags containing the drugs to be administered.
- Each bag is connected to the infusion line independently from the others by means of a series of valves and the dispensing of the drugs to the patient is done in succession, placing between the administration of one drug and the next an intermediate stage of cleaning of the infusion line by means of a lavage of a saline solution, so as to avoid any type of contamination between drugs.
- In other words, these types of therapeutic treatments consist in the following sequence of operations: administering of the first drug, cleaning of the infusion line, administering of the second drug, new cleaning of the infusion line, administering of the third drug, and so on.
- The drugs continue to be administered until the relevant bags containing the necessary doses prescribed by the doctor for the correct therapeutic treatment are completely empty.
- The filling of the bags with the above doses occurs during a delicate preliminary stage during which a hospital operator, with care and attention, doses the necessary quantities inside the bags.
- To perform this operation, the hospital technician usually has at disposal a series of bottles containing the drugs, from which he/she takes the required quantities and transfers these into the bags by means of a plurality of syringes (one for each drug, to avoid, in this case as well, any possible contamination between the fluids).
- For this purpose, each syringe is made up of a syringe body made of transparent material, on which is shown a graduated measuring scale and inside which is fitted, sealed, a sliding piston, which is manually operated by the operator by means of a thrust rod.
- The entire operation of taking, dosing and transferring drugs from the bottles to the bags, therefore, is performed in a completely manual way and without any automation, suctioning each drug inside the syringe body until the preset quantity is achieved indicated on the graduated scale and, then, dispensing the contents of the syringe inside the corresponding bag.
- As will be easily appreciated by a person expert in the sector, this sequence of operations involves a series of drawbacks, including the fact that, for the correct transfer and dosing of the drugs, the strength, capacity and experience of the operator are all important in performing such operation.
- In this respect, it must be pointed out that the considerable frequency with which these operations are performed often causes pain and/or lesions to the hands of the operator, who has to manually force on the thrust rod to draw the drugs up inside the syringes and, subsequently, to dispense them.
- At the same time, the fact cannot be ignored that the correct dosing of the drugs inside the syringes depends only on the care and skill of the operator and that, in the case of wrong dosage, the risk exists of compromising the successful outcome of the therapy prescribed by the doctor during the patient administering stage.
- In this respect, it must be underscored that the repetitiveness and monotony of the dosing operation cannot but increase the risk of lack of attention on the part of the operator while performing his/her duties and, consequently, the probability of an imprecise and incorrect dosage.
- The main aim of this invention is to provide a device for transferring and dosing biomedical fluids between hospital containers which is portable and versatile, allows dosing biomedical fluids in a practical, easy, functional and precise way, allows reducing the efforts on the part of the operator and the consequent accidents/lesions, and allows reducing the risk of human error without changing the normal use procedure and/or the work schedules.
- Another object of this invention is to provide a device for transferring and dosing biomedical fluids between hospital containers that allows overcoming the mentioned drawbacks of the state of the art in the ambit of a simple, rational, easy and effective to use as well as low cost solution.
- The above objects are achieved by the present device for transferring and dosing biomedical fluids between hospital containers, comprising at least a syringe body for the containment of a biomedical fluid and at least a piston sealed fitted in a sliding way in said syringe body, said syringe body comprising a first extremity, having joining means to at least a first container from which taking the biomedical fluid and to at least a second container in which dispensing said biomedical fluid, and a second extremity opposite said first extremity, characterised by the fact that it comprises:
-
- a handle for the manual grip by a user and having a coupling seat for the fastening to said second extremity of the syringe body;
- motorised means mounted in said handle for the operation of a thrust rod suitable for pushing said piston;
- first temporary fastening means placed between said coupling seat and said second extremity of the syringe body;
- second temporary fastening means placed between said piston and said thrust rod; and
- control means mounted on said handle, associated with said motorised means and suitable for the volumetric dosing both of the quantity of said biomedical fluid to take from said first container and of the quantity of said biomedical fluid to dispense in said second container.
- Other characteristics and advantages of the present invention will become more evident from the description of a preferred, but not sole, embodiment of a device for transferring and dosing biomedical fluids between hospital containers, illustrated purely as an example but not limited to the annexed drawings in which:
-
FIG. 1 is a front, schematic and partial view that illustrates an infusion line using the devices according to the invention to transfer and dose biomedical fluids; -
FIG. 2 is an exploded, schematic and partial view of a device according to the invention; -
FIG. 3 is a side view of the device ofFIG. 2 . - With particular reference to such figures, a device for transferring and dosing biomedical fluids between hospital containers is globally indicated by 1.
- In this respect, it must be underscored that in this treatise the term “biomedical fluid” means any liquid used in the medical/hospital field and intended to be administered to a patient by means of bags or other containers and which requires being precisely pre-dosed.
- In the particular embodiment shown in
FIG. 1 , the biomedical fluids consist of a series of drugs F1, F2, F3, F4, e.g., for oncology therapy use, contained in an equal number of first containers R1, R2, R3, R4 such as bottles or the like. - From the bottles R1, R2, R3, R4 the biomedical fluids F1, F2, F3, F4 must be taken and dispensed into an equal number of second containers P1, P2, P3, P4, of the type of bags or the like, to be connected to an infusion line L having a bag S of saline solution C and having specific cutout valve means V.

- Each device 1 comprises a
syringe body 2 for containing the biomedical fluid F1, F2, F3, F4 and apiston 3 seal fitted sliding in thesyringe body 2. - The
syringe body 2 is composed of, e.g., a cylinder-shaped tubular element made of transparent, coloured or matt plastic material (polyurethane, polycarbonate, polyethylene, etc.). - The dimensions of the
syringe body 2 can usefully vary according to the required containing capacity (e.g.: 10 ml, 20 ml, 30 ml, 50 ml, 60 ml). - The
syringe body 2 has afirst extremity 2 a, having joiningmeans 4 for joining to the first containers R1, R2, R3, R4 and to the second containers P1, P2, P3, P4, and asecond extremity 2 b opposite thefirst extremity 2 a. - More in detail, the
first extremity 2 a terminates with anextremity cap 5 supporting thejoining means 4, which, preferably, are of the Luer and Luer-Lock type. - The
second extremity 2 b, on the other hand, is shaped to define across separation wall 6, having acentral hole 7. - The whole, made up of a
syringe body 2,piston 3 andextremity cap 5 in point of fact makes up aninterchangeable cartridge 8, which can be distributed on the market already assembled, i.e., with thepiston 3 already fitted in thesyringe body 2 through thefirst extremity 2 a and with thefirst extremity 2 a closed again by means of theextremity cap 5. - Each device 1 also comprises a
handle 9 for the manual grip by a user and has acoupling seat 10 for fastening to thesecond extremity 2 b of thesyringe body 2. - The
handle 9 has an ergonomic shape, with at least a portion inanti-slip material 11 to increase the fastness and the grip of the user's hand. - Inside the
handle 9 are fitted motorised means 12 to drive athrust rod 13 suitable for pushing thepiston 3. - The motorised means 12, e.g., are made up of a linear actuator connected to the
thrust rod 13 and suitable for achieving the straight to-and-from movement of thethrust rod 13. - The
motorised means 12 are associated with apower supply battery 14 mounted in thehandle 9; thepower supply battery 14 is preferably of the rechargeable type and is associated with twoterminals 15 for connecting to a recharging station, but alternatively, it cannot be ruled out that this is made up of one or more disposable type batteries. - The
cartridge 8 is intended to be fitted on thehandle 9 with thecross separation wall 6 facing thecoupling seat 10, in correspondence to which thethrust rod 13 protrudes from thehandle 9 and is intended to cross thetransit hole 7 to operate thepiston 3. - Between the
coupling seat 10 and thesecond extremity 2 b of thesyringe body 2 are placed first temporary fastening means 16, 17, for the slot-in fitting of thecartridge 8 on thehandle 9. - Similarly, between the
piston 3 and thethrust rod 13 are placed second temporary fastening means 18, 19 to allow the connection and dragging of thepiston 3 by thethrust rod 13. - The first temporary fastening means 16, 17 and the second temporary fastening means 18, 19, e.g., are of the bayonet type, but it cannot be ruled out that alternatively they be slotted in or consist of a connection by friction or the like.
- On the
handle 9, furthermore, are fitted control means 20, 21 associated with themotorised means 12 and suitable for controlling their operation to obtain the volumetric dosage, including the micro-volumetric type dosage, both of the quantity of biomedical fluid F1, F2, F3, F4 to be taken from the first containers R1, R2, R3, R4, and of the quantity of biomedical fluid F1, F2, F3, F4 to be dispensed into the second containers P1, P2, P3, P4. - The control means 20, 21 comprise a processing and
control unit 20 and acontrol interface 21, of the type of a keypad or the like, for controlling themotorised means 12 and designed to start/stop/set the processing andcontrol unit 20 according to the user's requirements. - For this purpose, the processing and

syringe body 2 and thepiston 3 being stably coupled, with slot-in coupling, to thecoupling seat 10 and to thethrust rod 13 respectively, so as to prevent their accidental disassembly during use. - The present invention operates as follows.
- Each
handle 9 is prepared to be conveniently used with an indefinite number ofcartridges 8 inasmuch, at the end of their normal life cycle, these can be separated from thehandle 9, rejected and replaced by new ones. - At the start of the life cycle of each
cartridge 8, this is coupled on thehandle 9 being careful to correctly couple thesyringe body 2 to thecoupling seat 10. - Once the first temporary fastening means 16, 17 have been coupled, the processing and
control unit 20 automatically commands the forward movement of thethrust rod 13 until this is coupled with thepiston 3. - In this phase, the processing and
control unit 20 proceeds to identify thecartridge 8 by means of the identification means 24 and performs recognition of the correct coupling of the first temporary fastening means 16, 17 and of the second temporary fastening means 18, 19 and, in the case of positive outcome, allows the subsequent operation of the motorised means 12. - At this point all the user has to do is connect the joining
means 4 to the corresponding first container R1, R2, R3, R4 and, by means of the control means 20, 21, perform the withdrawal of the required quantity of biomedical fluid F1, F2, F3, F4 and fill thesyringe body 2. - Afterwards, by coupling the joining
means 4 to the second corresponding container P1, P2, P3, P4, the biomedical fluid F1, F2, F3, F4 can be dispensed and the device 1 is ready for the subsequent operations. - Using the
same handle 9 and thesame cartridge 8, all the transfers can be made of the biomedical fluid F1, F2, F3, F4 contemplated according to the normal life cycle of thesyringe body 2 and of thepiston 3. - After various uses and after some time from the first use, in fact, the
cartridge 8 becomes worn and contaminated and has to be replaced with a new one in the same way as previously described and shown. - As it has been said, in the embodiment shown in the
FIG. 1 , the use is contemplated of a plurality of devices 1, or at least a plurality ofhandles 9, one for each drug F1, F2, F3, F4, but nothing prevents having just onehandle 9 and a plurality ofcartridges 8 to be used alternately with thehandle 9 to transfer the drugs F1, F2, F3, F4, being careful to use eachcartridge 8 with one and only one drug F1, F2, F3, F4.
