Rubber valve and anti-self-adhesion medical infusion connector

Abstract

The invention discloses a rubber valve. A manufacturing process comprises the following steps: step 1) carrying out first-time vulcanization to form a colloid valve body, wherein the material of the colloid valve body is rubber or silica gel; step 2) cutting the colloid valve body to form a liquid through hole which is sealed at a normal state; step 3) smearing the liquid through hole with volatile liquid; step 4) carrying out second-time vulcanization on the colloid valve body smeared with the volatile liquid. According to the rubber valve disclosed by the invention, the volatile liquid is smeared on the cut and the second-time vulcanization is carried out so that a cut surface can be sufficiently cured and shaped, so that a condition that the cut is adhered after long-time contact can beprevented from occurring. The manufacturing process is used for the rubber valve and an infusion connector is used for medical equipment.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a rubber valve and an anti-self-adhesive medical infusion joint. Background technique [0002] Currently, the needle-free infusion joints on the market are basically composed of upper shell, lower shell and rubber valve body. In order to realize needle-free infusion, an incision is usually made at the head end of the rubber valve body. The incision of the rubber valve body is opened, and then the infusion is performed. However, the incision of the rubber valve body is self-adhesive after a long time of fitting before use, which leads to the phenomenon that the incision cannot be opened, and then affects the infusion treatment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rubber valve body and an anti-self-adhesive medical rubber valve. [0004] The solution that the present invention solves its technical problem i...
