Embodiment 1

[0077] Please combine Figure 1-Figure 4 It should be understood that this embodiment provides a liquid feeding pump system, which includes a casing 10 , an elastic liquid storage device 30 , a restrictor tube 40 , and a filter 50 . The liquid feeding pump system also includes a liquid feeding passage, which passes through the elastic liquid storage device 30 , the filter 50 and the restrictor tube 40 in sequence.

[0078] The elastic liquid storage device 30 includes: a liquid storage bag 31 , an isolation membrane 32 , a first cover 33 and a second cover 34 , and a pre-filled medicine 35 . The liquid storage bag 31 is provided with a liquid storage inner cavity 311 . The liquid storage bag 31 is hollow, and the material of the liquid storage bag 31 is an extensible material. The isolation film 32 covers the outer surface of the liquid storage bag 31 . The first cover 33 and the second cover 34 are buckled on the outer surfaces of the two ends of the isolation membrane 32 re...

Embodiment 2

[0090] Such as Figure 5-Figure 7 As shown, the overall structure of the liquid feeding pump system in this embodiment is basically the same as that in Embodiment 1, the difference lies in that the liquid feeding pump system also includes a drug adding member 20 and a liquid filling passage. The medicine adding part 20 is located in the housing 10 , and one end communicates with the connection cavity 371 of the elastic liquid storage device 30 . The liquid filling passage reaches the elastic liquid storage device 30 through the medicine adding part 20 . Specifically, one end of the medicine adding part 20 is inserted into the connection chamber 371 and communicated with the connecting cavity 371 , and the other end of the medicine adding part 20 is passed through the casing 10 .

[0091] The side wall 13 of the housing 10 is also provided with a drug feeding hole 15 , and one end of the drug feeding member 20 is penetrated in the drug feeding hole 15 .

[0092] In this embod...

Embodiment 3

[0094] Such as Figure 8 As shown, the overall structure of the liquid feeding pump system in this embodiment is basically the same as that in Embodiment 2, the difference is that the positioning sleeve 37 also includes a through hole 372, and the connecting cavity 371 includes a first part connected to 3711 and the second part 3712, one end of the connecting body 36 is located in the first part 3711 of the connecting cavity 371, one end of the through hole 372 communicates with the second part 3712 of the connecting cavity 371, and the other end of the through hole 372 communicates with the liquid storage inner cavity 311 In communication, the angle formed by the central axis of the first part 3711 of the connecting cavity 371 and the central axis of the second part 3712 of the connecting cavity 371 is a first included angle. That is to say, the connecting body 36 extends along the central axis direction of the first part 3711 of the connecting cavity 371 , and the medicine-f...

Abstract

The invention discloses a liquid feeding pump system which comprises an elastic liquid storage device. The elastic liquid storage device comprises a liquid storage bag provided with a liquid storage inner cavity, an isolation film covering the outer surface of the liquid storage bag, a first cover body and a second cover body respectively buckled on the outer surfaces of the two ends of the isolation film, and a to-be-pre-filled liquid medicine located in the liquid storage inner cavity. According to the liquid feeding pump system, the to-be-pre-filled liquid medicine is filled in the liquid storage inner cavity, so that a patient can directly use the liquid feeding pump system, and the liquid feeding pump system is convenient, fast, safe and reliable to use; meanwhile, the situation is avoided that the liquid medicine is confused when a syringe is used for preparing liquid medicine, and the operation of medical personnel is facilitated.

Description

technical field [0001] The invention relates to a liquid feeding pump system. Background technique [0002] At present, the volume of the existing liquid supply pump parts is too large, and it is not easy for the patient to carry during use, resulting in inconvenient activities; at the same time, the existing liquid supply pump components are only supplied to the liquid supply through the syringe for dosing when in use. After the pump part is injected with the liquid medicine, it is very inconvenient to inject the liquid medicine to the patient through the liquid pump part. The wrong use of injection medicine. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a liquid feeding pump system in order to overcome the inconvenient defect of infusion pump components without medical liquid in the prior art. [0004] The present invention solves the above technical problems through the following technical solutions: [0...
