Embodiment Construction

[0030] Such as figure 1 As shown, this embodiment provides a high-flow needle-free valve joint, including a valve 1 , a housing and a retaining ring 3 .

[0031] The glue valve 1 includes a small disc 11, a large disc 12 and a connecting block 13, one end of the connecting block 13 is connected to the small disc 11, and the other end is connected to the large disc 12, and the three are coaxial. The rubber valve 1 is provided with a liquid channel 14 that runs through the large disc 12, the small disc 11 and the connecting block 13 along the axial direction. The segments form duckbill valves 27 . The center of the top surface of the small disc 11 is provided with a guiding concave surface, the edge is provided with a card slot, and the edge of the large disc is provided with a downward fold.

[0032] The shell includes an upper shell 21 and a lower shell 22. The upper shell 21 includes an upper half and a lower half. The radius of the upper half is smaller than that of the lo...

Abstract

The invention relates to the field of medical supplies and discloses a high-flow needle-free rubber valve connector. The connector comprises a rubber valve, a shell and a fixed check ring, wherein the fixed check ring comprises an annular base and a plurality of arc-shaped side plates, the arc-shaped side plates are fixedly connected to the inner diameter of the annular base, an arc-shaped supporting platform is arranged on inner diameters of the arc-shaped side plates, the arc-shaped supporting platform supports the upper part of the rubber valve, the fixed check ring is connected with the shell in an inserted mode, the fixed check ring can effectively fix the rubber valve, vertical displacement of the rubber valve caused by compression is prevented, production and assembly are facilitated, and meanwhile, the medicine flow is increased. The needle-free connector is mainly applied to circumstances such as transfusion, and the safety problem caused by using glue to mount the rubber valve and the problem that the connector is out of action due to the fact that the rubber valve falls off can be effectively avoided.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a large-flow needle-free glue valve joint. Background technique [0002] In recent years, with the innovation and development of technology, a variety of needle-free infusion connector vaccinations focusing on safety injections have come out. Needle-free infusion connectors have also gone through earlier blunt needle designs, complex mechanical valves, and today's simple and transparent positive-pressure needle-free connectors. In the prior art, the internal glue valve of the needleless joint is generally fixed with glue. On the one hand, there are some safety hazards even if medical glue is used. The valve falls off, thereby losing the original function of the needle. At the same time, the needleless connector connected by glue still has the problem of difficult assembly. Contents of the invention [0003] The technical problem to be solved by the present invention is to prov...
