Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a multi-channel connector with a switchable infusion pipeline. Background Technique

[0002] In the existing medical infusion environment, usually multiple infusion bags are required for a patient during infusion. When one infusion bag is finished, a nurse needs to unplug and replace it with a second infusion bag for the infusion operation. Sometimes, when the nurse is busy and unable to replace it in time, blood backflow and air entering the infusion pipeline may occur when the patient doesn't know how to handle it or is inconvenient to replace the infusion bag.

[0003] (See Figure 1 ) The current common infusion method: The traditional infusion set includes a venous needle 1, a cap 2, a flow regulator 3, a drug filter 4, a bottle stopper puncture device 5, and an infusion hose 6. When switching infusion bags during infusion, a nurse needs to replace it. Since it is inconvenient for the patient to switch by themselves, it is difficult to unplug and insert the infusion bag by themselves.

[0004] Therefore, through beneficial exploration and research, the applicant has found a method to solve the above problems, and the technical solution to be introduced below is generated under this background. Content of the Utility Model

[0006] The technical problem to be solved by the utility model can be achieved by adopting the following technical solutions:

[0007] A multi-channel connector with a switchable infusion pipeline, including an infusion set, characterized in that it further includes a multi-channel main body provided on the infusion set and used for self-switching the infusion pipeline. One end of the multi-channel main body is provided with at least one multi-channel joint for connecting with an infusion bottle puncture device, and the other end of the multi-channel main body is provided with a connection joint for connecting with the infusion set.

[0008] In a preferred embodiment of the utility model, the multi-channel main body includes a housing, an inner component movably arranged in the housing and communicating with the infusion pipeline of the infusion set, and a housing cover provided on the housing for sealing the inner component.

[0009] In a preferred embodiment of the utility model, the inner component includes an arc-shaped block rotatably moving in the housing, and a connection channel communicating with the infusion pipeline is arranged inside the arc-shaped block.

[0010] In a preferred embodiment of the present invention, the surface of the housing cover is provided with an arc-shaped groove that cooperates with the arc-shaped block.

[0011] In a preferred embodiment of the present invention, a sealing ring is provided inside the housing.

[0012] Due to the adoption of the above technical solution, the beneficial effect of the present invention is that the patient can adjust the switch with one hand. When the infusion of one infusion bag is completed, the patient can switch the infusion bag with one hand to continue the infusion, which is simple to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0023] See also Figures 2 to 8The multi-channel connector for switchable infusion lines shown includes an infusion set 10 . The infusion set 10 in this embodiment includes a venous needle 11 , a protective cap 12 , a flow rate regulator 13 , a liquid medicine filter 14 , and an infusion line 15 .

[0024] The infusion set 10 also includes a multi-channel body 20, which is mounted on the infusion set 10 and is used to automatically switch infusion lines. One end of the multi-channel body 20 is provided with at least one multi-channel connector 20a for connecting to the bottle inserter 30. The other end of the multi-channel body 20 is provided with a connecting connector 20b for connecting to the infusion set 10. In this embodiment, there are three multi-channel connectors 20a, which are arranged at intervals.

[0025] The multi-channel body 20 includes a housing 21, an inner assembly 22 movably disposed within the housing 21 and communicating with the infusion tube 15 of the infusion set 10, and a housing cover 23 disposed within the housing 21 and sealing the inner assembly 22. In this embodiment, the inner assembly 22 includes an arcuate block 22a movably rotatable within the housing 21. A connecting channel 22b communicating with the infusion tube 15 is disposed within the arcuate block 22a.

[0026] In order to facilitate the operation of the internal components, the surface of the housing cover 23 is provided with an arc groove 23a that cooperates with the arc block 22a.

[0027] In order to seal the internal components, a sealing ring 21 a is provided inside the housing 21 .

[0028] The working principle of this utility model is as follows:

[0029] First, the three multi-channel connectors 20a at one end of the multi-channel main body 20 are connected to the three bottle inserters 30, and the connecting connector 20b at the other end of the multi-channel main body 20 is connected to the infusion pipe 15 of the infusion set 10. When infusion is needed, the three bottle inserters 30 are inserted into the three multi-channel connectors 20a. Then, the medical staff or the patient operates the arc block 22a to make the connecting channel 22b in the multi-channel main body 20 and the infusion pipe 15 and the multi-channel connector 20a a unified channel for infusion. When the infusion is completed, twist the arc block 22a to move to the next multi-channel connector 20a so that the bottle inserter 30 on the next multi-channel connector 20a is inserted into the infusion bag. Similarly, the connecting channel 22b in the multi-channel main body 20 and the infusion pipe 15 and the multi-channel connector 20a are a unified channel for infusion, which is convenient for operation.

[0030] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model.
