Abstract
A disposable drug storing device for an insulin infusion pump comprises a drug storing pipe and a piston cap, wherein the piston cap after being sealed is arranged in the drug storing pipe, and can be moved backwards in the drug storing pipe, the rear end of the piston cap is provided with a compatible type assembly opening, and the compatible type assembly opening is connected with a drug picking dedicated rod or an axial piston mechanism of an infusion pump driving component in matched mode. The disposable drug storing device for the insulin infusion pump has the advantages that the drug picking dedicated rod exclusively used for extracting drug liquid is arranged in addition on the basis that functions of a traditional piston rod are integrated into intrinsic functions of an infusion pump driving system, and therefore the structure of the disposable drug storing device which really needs to be replaced is simplified, and furthermore the disposable drug storing device is simple and convenient to replace, and safe and practical.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to the medicine storage device of portable insulin infusion pumps.
Background technology
The groundwork principle of portable insulin infusion pump is: move forward and backward by the micro machine driven plunger, by piston, the medicinal liquid in the drug storage pipe is expelled to human body regularly, quantitatively, micro machine is controlled by microprocessor and drive circuit.Wherein, owing to relating to injecting liquid drug, the medicine storage device in insulin infusion pumps is necessary for disposable device, needs often to change.
Existing medicine storage device structure is: comprise drug storage pipe, piston rod and sealing ring, the piston rod front outer is installed sealing ring, piston rod front portion and sealing ring are arranged in the drug storage pipe movably, the rear axle of piston rod is to offering screwed hole, a screw mandrel threaded of this screwed hole and driven by motor.The defective of prior art is: piston rod makes the infusion pump complex structure as requisite device in the infusion pump work process, changes also inconvenient.
So, can consider the piston rod of prior art is accomplished in the intrinsic driven unit of infusion pump, and as an intrinsic axial piston machine, just can simplify on this basis the structure of disposable medicine storage device, simplified structure just more utilizes and changes.
The utility model content
The purpose of this utility model is to provide a kind of for the disposable medicine storage device on insulin infusion pumps, simplifies the structure of disposable device, and it is more convenient to make the replacing of medicine storage device.The technical scheme that realizes above-mentioned purpose is as follows:
A kind ofly comprise drug storage pipe and piston cap for the disposable medicine storage device on insulin infusion pumps, piston cap sealing and can be arranged on movably forward and backward in the drug storage pipe; It is characterized in that: the piston cap rear end is provided with a compatible type installation opening, and this compatible type installation opening is used for and is connected the get it filled axial piston machine of special pole or infusion pump driven unit connecting cooperation.
As concrete technical scheme, described compatible type installation opening is an elasticity slotted eye.
As concrete technical scheme, described compatible type installation opening is a screwed hole.
As concrete technical scheme, described piston cap is made of the sealing ring of body and outer rim setting.
The beneficial effects of the utility model are: conventional piston bar function is being integrated on the basis of infusion pump drive system inherent function, configure in addition one and be exclusively used in the special pole of getting it filled that extracts medicinal liquid, made the designs simplification of the real disposable medicine storage device that need to change, replacing is got up easier, and safe and practical.
Description of drawings
The exploded view of the disposable medicine storage device that Fig. 1 provides for embodiment.
The schematic diagram of the embodiment disposable medicine storage device that provides and the special pole its pre-mated of getting it filled is provided Fig. 2.
The disposable medicine storage device that Fig. 3 provides for embodiment and the schematic diagram of infusion pump driven unit axial piston machine its pre-mated.
The specific embodiment
As shown in Figure 1, as shown in Figure 1, the disposable medicine storage device that the present embodiment provides comprises drug storage pipe 10 and piston cap 20, and piston cap 20 comprises that body 22 and 23, two sealing rings 23 of two sealing rings are arranged on body 22 outer rims.
Continuation is referring to Fig. 1, and piston cap 20 rear ends are provided with a compatible type installation opening 25, and described compatible type installation opening is an elasticity slotted eye or is a screwed hole.This compatible type installation opening 25 is connected cooperation with the special pole 30 of getting it filled when extracting medicinal liquid, in conjunction with Fig. 2.Lose the special pole 30 of getting it filled after extracting medicinal liquid, drug storage pipe 10 be installed in infusion pump, and make the axial piston of compatible type installation opening 25 and infusion pump driven unit (are connected with piston bush by motor 40 etc. consist of) overlap 50 to be connected cooperation, under referring to Fig. 3.
Above embodiment is only for fully open unrestricted this utility model, for the simple replacement that can know without creative work, or the increase and decrease of constructed feature, should belong to the application scope of disclosure.
