[0001] This utility model relates to the field of medical device technology, and in particular to a disposable pump infusion set with multi-stage filtration. Background Technology

[0002] The medication contains a large number of insoluble particles (carbon particles, bacteria, fat emboli, rubber, plastic, etc.) and impurities. During infusion, these insoluble particles and impurities can enter the body through the infusion, which may lead to potential and long-term harm. Utility Model Content

[0003] The purpose of this invention is to provide a disposable pump infusion set with multi-stage filtration, which solves the problem that insoluble particles and impurities may enter the body through the infusion during infusion, potentially causing long-term harm.

[0004] To achieve the above objectives, this utility model provides a multi-stage filtration disposable pump infusion set, including tubing, a pump tube, and a filtration assembly. The filtration assembly includes an inlet tube, a filter, a filter head, and an outlet tube. There are two inlet tubes, each connected to the pump tube and located in the middle of the pump tube. There are two filters, each connected to the inlet tube and located outside the inlet tube. There are two filter heads, each fixedly connected to the inlet tube and located inside the filter. There are two outlet tubes, each connected to the filter and located between the filter and the pump tube.

[0005] The multi-stage filtered disposable pump infusion set further includes a puncture device and a locking connector. The puncture device is connected to the tubing and located at one end of the tubing, and the locking connector is connected to the pump tube and located at the tail end of the pump tube.

[0006] The multi-stage filtration disposable pump infusion set also includes a drip chamber, which is connected to the pipeline and located in the middle of the pipeline.

[0007] The multi-stage filtration disposable pump infusion set also includes two ports, which are connected to the pipeline and located between the pipeline and the pump tube.

[0008] The multi-stage filtration disposable pump infusion set further includes a sheath and a regulator. The sheath is connected to the pump tube and located outside the pump tube, while the regulator is connected to the pump tube and located between the sheath and the filter.

[0009] This utility model relates to a multi-stage filtration disposable pump infusion set. The tubing connects to the medication bottle, the pump tube connects to the infusion pump, the inlet tube introduces the medication from the pump tube into the filter, the filter and the filter head filter the medication, and the outlet tube re-introduces the filtered medication into the pump tube. In use, a puncture device punctures the medication bottle stopper to connect to the medication bottle. The pump tube, compressed by the infusion pump, creates negative pressure to draw out the medication. The medication flows through the puncture device, the tubing, the drip chamber, the two-way valve, the pump tube, the sheath, the regulator, the filter assembly, and the locking connector. The medication undergoes repeated filtration through multiple filter assemblies, improving filtration efficiency and addressing the problem that insoluble particles and impurities may enter the body during infusion, potentially causing long-term harm.

[0015] The first embodiment of this application is as follows:

[0016] Please see Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of the overall structure of the multi-stage filtration disposable pump infusion set according to the first embodiment of this utility model. Figure 2This is a schematic diagram of the structure of the filter assembly of the first embodiment of the present invention. The present invention provides a multi-stage filtration disposable pump infusion set, including a tubing 101, a pump tube 102, a puncture device 103, a locking connector 104, a drip chamber 105, a two-way connector 106, a sheath 107, a regulator 108, and a filter assembly. The filter assembly includes an inlet tube 109, a filter 110, a filter head 111, and an outlet tube 112. The aforementioned solution solves the problem that insoluble particles and impurities may enter the body through the infusion during infusion, potentially causing potential and long-term harm.

[0017] In this specific embodiment, there are two inlet pipes 109, each connected to a pump pipe 102 and located in the middle of the pump pipe 102. There are two filters 110, each connected to an inlet pipe 109 and located outside the inlet pipe 109. There are two filter heads 111, each fixedly connected to an inlet pipe 109 and located inside the filter 110. There are two outlet pipes 112, each connected to a filter 110 and located between the filter 110 and the pump pipe 102. The conduit 101 is used to connect to a medicine bottle. The pump pipe... 102 is used to connect to an infusion pump. The inlet pipe 109 is used to introduce the medicine solution in the pump pipe 102 into the filter 110. The filter 110 and the filter head 111 are used to filter the medicine solution. The outlet pipe 112 is used to introduce the filtered medicine solution back into the pump pipe 102. In use, the puncture device 103 is used to puncture the stopper of the medicine bottle to connect the medicine bottle. The pump pipe 102 is squeezed by the infusion pump to form a negative pressure to draw out the medicine solution. The medicine solution flows through the puncture device 103, the tubing 101, the drip chamber 105, the two-way connector 106, the pump pipe 102, the sheath 107, the regulator 108, the filter assembly, and the locking connector 104. The medicine solution flows through multiple filter assemblies for repeated filtration to improve the filtration efficiency of the medicine solution.

[0018] The puncture device 103 is connected to the tubing 101 and is located at one end of the tubing 101. The locking connector 104 is connected to the pump tube 102 and is located at the tail end of the pump tube 102.
