[0031] like Figures 2 to 8 As shown, an infusion set leak detector comprises a leak detection platform 2, a test seat 3 is fixedly connected to the leak detection platform 2, a positioning hole 32 is provided on the test seat 3 for positioning the infusion set connector 11, a test assembly is provided on the test seat 3, the test assembly comprises a test drive unit 41, a test piece 42 and an air pressure detection element 43, the test piece 42 can slide along the axial direction of the positioning hole 32, the test piece 42 is transmission-connected to the test drive unit 41, the test piece 42 is provided with a test hole 421 capable of air-tight contact with the port of the infusion set connector 11, and the test piece 42 is also provided with an air inlet hole 42 2. The air inlet 422 is connected to an air inlet pipe, which can be connected to an air compressor or a high-pressure pipeline. The air inlet pipe is connected to an electrically controlled air inlet switch (not shown in the attached drawings). A test channel (not shown in the attached drawings) is provided on the inner side of the test piece 42. The test hole 421 and the air inlet 422 are both connected to the test channel. The test hole 421 is directly opposite to the positioning hole 32. The test drive unit 41 can drive the test piece 42 to approach or move away from the positioning hole 32 so that the test hole 421 compresses and seals or loosens the port of the infusion connector 11. The air pressure detection element 43 is connected to the test channel and can detect the air pressure of the test channel. The test drive unit 41 can adopt a drive structure such as a cylinder or a screw motion module, and the electrically controlled air inlet switch can adopt an electromagnetic valve. The air pressure detection element 43 can be directly connected to the test channel, or connected to the air inlet 422 through a pipeline and a three-way valve.
[0032] The leakage detection of the infusion set mainly simulates whether there is leakage during infusion. Therefore, this embodiment uses air as the medium and continuously sends air into the infusion set to simulate infusion. If the air flow in the infusion set is unstable, it indicates that there is leakage. A flow stabilizing valve can also be set on the air inlet pipe to stabilize the air flow entering the infusion set to avoid misjudgment caused by flow changes caused by leakage in the infusion set.
[0033] The infusion set connector 11 of the infusion set to be tested for leakage is horizontally placed in the positioning hole 32 of the test seat 3, with the port of the infusion set connector 11 facing the test piece 42, and then the test drive unit 41 drives the test piece 42 to approach and press the infusion set connector 11, so that the test hole 421 is sealed and connected with the port of the infusion set connector 11; then the electric control air intake switch opens the air intake pipe, and the air enters the infusion set connector 11 through the air intake pipe, the air intake hole 422, the test channel and the test hole 421, and the air flows through the infusion set catheter 12 And discharged from the infusion set puncture tube 13, the air keeps being transported into the infusion set for a period of time, and at the same time the air pressure detection element 43 detects the air pressure inside the infusion set and in the test channel. If the air pressure value detected by the air pressure detection element 43 is basically unchanged or changes within the set range, it means that the flow rate of air when flowing through the infusion set is basically unchanged, the infusion set does not leak or leaks less, and the leakage test result is qualified; if the air pressure value changes outside the set range, it means that there is obvious leakage when the air flows through the infusion set, and the leakage test result is unqualified.
[0034] The test assembly of the infusion set leak detector can automatically seal the port of the infusion set connector 11 and detect the air pressure, reducing manual operation and judgment, reducing the problem of misoperation and misjudgment, and has a simple structure, which can reduce the cost of the equipment. After the detection is completed, the test drive unit 41 drives the test piece 42 away from the loosened infusion set connector 11, and the infusion set can be removed manually.
[0035] In some specific embodiments, referring to Figure 3 , Figure 6 and Figure 7 The test seat 3 is also provided with a blocking component, which includes a blocking drive unit 51 and a blocking member 52.

The avoidance groove 521 faces the positioning hole 32, and the width of the avoidance groove 521 is smaller than the width of the positioning hole 32. The blocking member 52 is transmission-connected with the blocking drive unit 51. The blocking drive unit 51 can drive the blocking member 52 to approach or move away from the positioning hole 32 so that the two sides of the avoidance groove 521 block or release the infusion connector 11.
[0036] The positioning hole 32 is configured to match the shape of the infusion connector 11. When the infusion connector 11 is placed in the positioning hole 32, Figure 6, the blocking driving unit 51 drives the blocking member 52 to move toward one side of the positioning hole 32, referring to Figure 7 , the infusion set catheter 12 enters the avoidance groove 521, and the two sides of the avoidance groove 521 block the infusion set connector 11, and the avoidance groove 521 avoids the infusion set catheter 12, and then the test piece 42 presses the infusion set connector 11 against the blocking piece 52, so as to achieve the sealing of the test hole 421 and the infusion set connector 11, and the structure is simple. The blocking drive unit 51 can adopt a driving structure such as a cylinder or a screw motion module. After the detection is completed, the test piece 42 moves away from the release of the infusion set connector 11, and the blocking drive unit 51 drives the blocking piece 52 away from the release of the infusion set connector 11, and the infusion set connector 11 can be removed manually.
