Problems solved by technology

The shortcomings of the current test are: (1) when the container is shaken, the falling debris that has fallen into the water may adhere to the piercer or the combination cover, and eventually be lost with the removal of the combination cover, thereby affecting the test accuracy; (2) At present, the step of inserting the puncture device is done manually. In the face of a large number of samples, the insertion depth of the puncture device cannot be kept consistent, which affects the accuracy of the test.

Embodiment 1

[0051] Such as Figure 1-Figure 15 As shown, a puncture falling chip test device includes a main bracket 6, a cylindrical cam 7, a puncture device, a puncture device support 8, a syringe, a water tank 9, a clamp and a damping mechanism.

[0052] Such as figure 1 and figure 2 As shown, the puncture device includes a needle body 1 and a quick intubation connector 5. One end of the needle body 1 is provided with a conical needle 2, and the needle body 1 is provided with a water injection channel 3. The water injection channel 3 is machined by electric discharge. A water outlet 4 is provided on the conical surface, and the water outlet 4 communicates with the water injection channel 3 . The quick intubation connector 5 is threadedly connected with the needle body 1 and is communicated with the water injection channel 3, and is used for quick connection with the pipeline.

[0053] If the diameter of the water outlet 4 is too large, the circumference of the incision formed on th...

Embodiment 2

[0070] Such as Figure 16 and 17 As shown, the trocar in this embodiment includes a needle body 1 and a quick intubation connector 5. One end of the needle body 1 is provided with a conical needle 2, and a water injection channel 3 is provided inside the needle body 1, which is different from the first embodiment. Four water outlets 4 are provided on the conical surface of the needle 2 and are evenly spaced along the circumference of the needle 2 . The water outlets 4 communicate with the water injection channel 3 . The water injected into the water injection channel 3 flows out along a plurality of evenly distributed water outlets 4, the coverage area of ​​the water flow is relatively large, and the flushing effect on the falling debris is good.

Embodiment 3

[0072] Such as Figure 18 As shown, the trocar in this embodiment includes a needle body 1 and a quick intubation connector 5. One end of the needle body 1 is provided with a conical needle 2, and a water injection channel 3 is provided inside the needle body 1, which is different from the first embodiment. The water outlet 4 is arranged on the outer circular surface of the needle body 1 , and the water outlet 4 communicates with the water injection channel 3 .

Abstract

The invention relates to the technical field of quality inspection equipment of a polypropylene combined cover for an infusion container, in particular to a puncture exfoliation test puncture outfit.The puncture exfoliation test puncture outfit comprises a needle body. A needle head is arranged at one end of the needle body. A water injection channel is formed in the needle body. A water outlet is formed in the outer circular surface of the needle body and / or in the conical surface of the needle head, and the water outlet is communicated with the water injection channel. The invention furtherprovides a puncture exfoliation test device which comprises the puncture outfit and further comprises a main support, a cylindrical cam, a puncture outfit support, an injector and a water tank. A curve groove is formed in the cylindrical cam. The puncture outfit support is provided with a first roller. The injector comprises an injector cylinder, a piston and a piston support. The piston supportis provided with a second roller. The connecting line of the first roller and the second roller penetrates through the axis of the cylindrical cam. The test precision can be improved, and the test steps are simplified.

Description

technical field [0001] The invention relates to the technical field of quality inspection equipment for polypropylene combined caps for infusion containers, in particular to a puncture device, device and method for puncturing debris testing. Background technique [0002] After the puncture needle is inserted into the infusion container, the polypropylene composite cover for the infusion container can seal the infusion container and prevent the puncture needle from falling off. Puncture debris refers to the particles that fall from the combined cover when the puncture needle is inserted into the combined cover. The puncture debris will enter the human body with the liquid medicine, causing infusion reactions, vascular embolism, phlebitis, allergic reactions, etc. Therefore, the puncture debris is the quality of the combined cover. Important indicators. [0003] The current puncture and debris test procedure for composite caps: Take a composite cap sample and assemble it on a...
