Referring to fig. 1-4, the present utility model provides a medical fluid infusion device 100 for infusing medical fluid into a human body, and capable of implementing mixed injection of multiple medical fluids.

A medical fluid infusion device 100 includes a base 10, a reservoir 20, a delivery assembly 30, a drive assembly 40, and a control assembly 50. The medicine storage bags 20 are at least two and are respectively arranged on the base 10 and used for containing medicine liquid to be infused, the driving assembly 40 is arranged at the top of each medicine storage bag 20, the conveying assembly 30 comprises a main pipe 31 and at least two branch pipes 32 communicated with the main pipe 31, each branch pipe 32 is correspondingly communicated with one medicine storage bag 20 and used for injecting the medicine liquid to be infused in the medicine storage bag 20 into the main pipe 31, the main pipe 31 is used for being connected with an external injection device, the control assembly 50 is electrically connected with the driving assembly 40, the driving assembly 40 is configured to press the medicine storage bags 20 in response to an electric signal sent by the control assembly 50, and the control assembly 50 can control the at least two driving assemblies 40 to simultaneously press the medicine storage bags 20.

Thus, the medicine storage bags 20 are at least two, so that the medicine liquid infusion device 100 can store a plurality of medicine liquids, each medicine storage bag 20 is communicated with one branch pipe 32, so that the medicine liquid in each medicine storage bag 20 can flow into the main pipe 31 through the branch pipe 32, and since one end of the main pipe 31 is connected with an external injection device, the medicine liquid can flow out of the medicine liquid infusion device 100 through the main pipe 31 to reach the external injection device, and the injection of the medicine liquid is realized. The outside of each medicine storage bag 20 is provided with a driving component 40, when the driving component 40 responds to the control component 50 to squeeze the medicine storage bags 20, the main bags are deformed, so that the internal medicine liquid is extruded, when the control component 50 controls at least two driving components 40 to operate, the medicine liquid in at least two medicine storage bags 20 can be extruded, and if the medicine liquid types in the medicine storage bags 20 are different, the mixing of multiple medicine liquids is realized. And the control assembly 50 can control any at least two driving assemblies 40 to simultaneously squeeze the medicine storage bags 20, so that various kinds of medicine liquid simultaneously enter the conveying assembly 30, the mixing is more uniform, and the mixing efficiency is higher.

Specifically, the driving assembly 40 has a first state in which the driving assembly 40 is at the initial position and a second state in which the driving assembly 40 moves toward the base 10 and the medicine liquid in the medicine storage bag 20 is completely extruded. In this way, since the driving assembly 40 can directly completely extrude the liquid medicine in the medicine storage bag 20, only the capacity of the liquid medicine in the medicine storage bag 20 is required to be fixed, the liquid medicine capacity in one medicine storage bag 20 is a minimum storage unit, and when the liquid medicine amount required to be extruded is an integer multiple of the minimum storage unit, the control is more accurate. For example, when the medicine liquid content in one medicine storage bag 20 is 0.25 microliter, if 1 microliter of medicine liquid needs to be injected, only four driving parts are required to be triggered, and the medicine liquid in four medicine storage bags 20 is extruded, so that 1 microliter of medicine liquid can be accurately extruded, and the control is more accurate.

Of course, in other embodiments, the drive assembly 40 may be configured to progressively squeeze the reservoir 20 in response to the control assembly 50, controlling the volume of liquid medicament expressed by varying its travel.

Further, at least two medicine storage bags 20 are arranged in a pairwise array, so that the internal structure of the medicine liquid infusion device 100 is more regular, the arrangement of internal elements is convenient, and the flow direction of medicine liquid is better controlled.

In another embodiment, at least two drug storage bags 20 are arranged in an annular shape, so that when the liquid medicine in the drug storage bags 20 flows into the main pipe 31 through the branch pipe 32, the path is smoother, and turbulence is reduced.

Of course, in other embodiments, the drug storage bags 20 may be arranged in a dispersed manner, which is only suitable for the working environment.

Thus, the first path 311 and the second path 312 are parallel, so that the medicine storage bags 20 are arranged on two sides of the first path 311 and two sides of the second path 312, the medicine storage bags 20 are arranged more regularly, and more medicine storage bags 20 are arranged under the same area.

Further, the medicine storage bags 20 on two sides of the first path 311 are axisymmetrically arranged, so that the processing and the assembly are convenient, and the medicine liquid in the medicine storage bags 20 on two sides can be heduled when being injected into the main pipe 31 through the branch pipe 32, so that the mixing is more uniform.

Various embodiments of the drive assembly 40 of the medical fluid infusion device 100 are contemplated, each of which is described herein:

example 1

Referring to fig. 1-3, the medical fluid infusion device 100 includes a support housing 60, wherein the support housing 60 is covered on the base 10, and forms a containing cavity with the base 10, and the medicine storage bag 20, the driving assembly 40 and a part of the conveying assembly 30 are located in the containing cavity. In this way, the supporting shell 60 can isolate the inside of the accommodating cavity from the outside, and protect the medicine storage bag 20, the driving assembly 40 and the conveying assembly 30 in the accommodating cavity from being interfered by external environmental factors.

Thus, since the expansion member 41 is mounted on the top surface of the drug storage bag 20 far from the base 10, after the expansion member 41 expands in response to an electrical signal, the side of the expansion member 41 facing away from the drug storage bag 20 is not limited in structure, so that the expansion member 41 will expand away from the drug storage bag 20 until the expansion member 41 abuts against the inner wall of the support shell 60 facing the base 10, the expansion of the expansion member 41 in this direction is limited, and at this time, the expansion force thereof acts against the drug storage bag 20 in the opposite direction, and as the expansion member 41 expands further, the drug storage bag 20 is further extruded until the drug solution is completely extruded. When the expansion member 41 is contracted, the pressing action against the drug reservoir 20 is eliminated, and at this time, the drug solution can be refilled into the drug reservoir 20 so that the drug solution infusion device 100 can be reused.

Preferably, the expansion member 41 is a piezoelectric ceramic, which can convert electric energy into mechanical energy, and has simple structure, low cost and stable operation. Of course, in other embodiments, the expansion member 41 may be a motor that can be driven by electric energy and a squeezing plate, and the motor converts the electric energy into mechanical energy after receiving the electric signal of the control assembly 50, and drives the squeezing plate through the transmission mechanism, and the squeezing plate squeezes the drug storage bag 20 to squeeze the drug liquid in the drug storage bag 20.

Example two

Referring to fig. 4, the driving assembly 40 includes a driving plate 42 and a telescopic member 43, wherein the driving plate 42 is disposed on one side of the drug storage capsule 20 far from the base 10, one end of the telescopic member 43 is connected with the driving plate 42, the other end of the telescopic member 43 is connected with the base 10, the telescopic member 43 is electrically connected with the control assembly 50 and is configured to be shortened or lengthened in response to an electrical signal of the control assembly 50, and the driving plate 42 can be pulled and moved toward the base 10 to press the drug storage capsule 20 as the telescopic member 43 is shortened. So, the drive plate 42 lid is located the one side that the base 10 was kept away from to medicine storage bag 20, so can be better with the extrusion force when the drive plate 42 moves and act on medicine storage bag 20, medicine storage bag 20 can receive the effort from base 10 and drive plate 42 two directions, and the liquid medicine is extruded more easily, and extensible member 43 is connected with base 10, makes things convenient for the layout of electric signal line, is favorable to extensible member 43 to be connected with control assembly 50 electricity, and extensible member 43 can be through self characteristic pulling drive plate 42, simple structure is stable.

Of course, in other embodiments, the drive plate 42 may be disposed at other locations on the drug reservoir 20, as long as squeezing of the drug reservoir 20 is achieved. For example, the driving plates 42 are provided at both sides of the medicine storage bag 20, and the medicine storage bag 20 is pressed by the opposite movement of the driving plates 42 at both sides; alternatively, the driving plate 42 is provided at one side of the medicine storage bladder 20, and the driving plate 42 is provided in a rotational movement, thereby achieving the squeezing of the medicine storage bladder 20.

Preferably, the telescoping member 43 employs a memory wire that changes its shape and configuration depending on ambient temperature, stress, or in response to a change in an electrical signal, thereby effecting a pulling of the drive plate 42.

In other embodiments, the telescoping member 43 may have other configurations, as long as it is capable of pulling the drive plate 42 in response to the control assembly 50. For example, with the combination of the elastic member and the stopper, the stopper can restrict the elastic member to an extended state, and as the control unit 50 issues a command, the stopper releases the restriction on the elastic member, and the elastic member shortens by its own elasticity, thereby pulling the driving plate 42.

In addition, the driving unit 40 may be configured to press the drug storage bag 20, such as a bimetal plate, instead of the first and second embodiments.

The utility model also provides medical equipment comprising the liquid medicine infusion device 100 and an injection device, wherein the liquid medicine infusion device 100 is communicated with the injection device.
