Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-7, the present invention provides a technical solution:

the utility model provides a dark vein is applied ointment or plaster with function is taken out to gaseous negative pressure, is pasted at the top of applying ointment or plaster 1 including applying ointment or plaster 1, and 2 middle parts of puncture pieces alternate and are connected with pjncture needle 21, and piercing element 3 is installed at the top of applying ointment or plaster 1, and piercing element 3's middle part alternates with pjncture needle 21 to be connected, applies ointment or plaster 1's one side fixed mounting's one-way valve mechanism 4.

When in specific use: in the process of puncturing, the applicator 1 is first stuck to the site where the patient punctures, and the puncture needle 21 of the puncture device 2 is inserted into the body of the patient through the puncture device 3, and the gas is discharged through the check valve mechanism 4.

In this embodiment: check valve mechanism 4 includes and applies ointment or plaster 1's surperficial fixedly connected with one-way air valve casing 41, gas pocket 411 has been seted up at the top of one-way air valve casing 41, fastener 42 is installed to the inside bottom of one-way air valve casing 41, the mid-mounting on fastener 42 top has reset spring 421, reset spring 421's middle part alternates and is connected with pressing rod 422, pressing rod 422's top install dog 43, fluting 44 has been seted up to the both sides at fastener 42 top, fluting 44 open-ended highly is greater than the height of dog 43 avris, pipeline 45 has been seted up to the both sides of fastener 42 bottom.

When the air bubble removing device is used specifically, when air bubbles generated in the middle of a puncture point are removed, firstly, the needle tube at one end of the needle tube is inserted into the air hole 411, one end of the needle tube pushes the stop 43 on the reset spring 421, so that the stop 43 moves downwards to reach the horizontal position of the slot 44, the needle rod is pulled to enable the rubber plug in the needle tube to suck out the air bubbles conveyed by the conveying pipeline 45, and the application plaster 1 is enabled to be tightly adhered to the skin.
