Embodiment Construction

[0020] The present invention will be described in detail below through specific examples.

[0021] A medical film-coated synthetic polyisoprene gasket, the formula of which is: polyisoprene rubber: 100, kaolin: 15-20, white carbon black: 5-10, zinc oxide: 5, Carbon black: 0.3, titanium dioxide: 4, vulcanizing agent: 1.2.

[0022] The thickness of the film material is 2mil ETFE film.

[0023] A medical film-coated synthetic polyisoprene gasket, the production process of which is as follows:

[0024] (1) Ingredients: Prepare various materials according to the formula and put them in the designated material hole;

[0025] (2) Rubber mixing: mix various materials evenly according to the formula;

[0026] (3) Preforming: According to the requirements, the rubber material is made into a film with a specified size and weight for vulcanization;

[0027] (4) Primary vulcanization: Put the formula rubber and membrane material on the flat vulcanizer to form the drug contact part of t...

Abstract

The invention discloses a polyisoprene gasket synthesized by a medicinal film and belongs to the technical field of medical product. The formulae of the polyisoprene gasket in parts by weight are as follows: 100 parts of polyisoprene rubber, 15-20 parts of kaolin, 5-10 parts of white carbon black, 5 parts of zinc oxide, 0.3 parts of carbon black, 4 parts of titanium dioxide and 1.2 parts of vulcanizing agent; the production process flow comprises the following steps: (1) preparing the materials; (2) refining rubber; (3) performing; (4) one-time vulcanizing; (5) one-time deflashing; (6) second-time vulcanizing; (7) second-time deflashing; and (8) washing. The polyisoprene gasket synthesized by the medicinal film has the following advantages: the defect of the bad adhesiveness of the traditional polyisoprene gasket and the film material is overcome, the rubber gasket product is directly contacted with the medical liquid so that the inner cap of a composite cover is omitted and the related requirement of directly contacting the transfusion medicine is met; due to a special structure design, the resistance of the puncture process is reduced in the using process, the generation of the puncture scraps is reduced and the polyisoprene gasket is convenient for the hospital use.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a medical film-coated synthetic polyisoprene gasket. Background technique [0002] The traditional medical infusion combination cap consists of outer cap + isoprene gasket + inner cap. Because the inner cap is made of PP material, it is difficult to puncture in actual use, and the puncture debris is large, which causes certain difficulties for infusion. and impact. [0003] In order to solve these problems, we have eliminated the inner cover in the development and design of the infusion combination cap, so that the gel pad product is in direct contact with the liquid medicine, so it is necessary to improve and innovate the production technology and process technology of the existing medicinal combination cap . Contents of the invention [0004] The object of the present invention is to provide a kind of medical film-coated synthetic polyisoprene gasket, which adopt...
