Problems solved by technology

Then, during the production and storage of the rubber gasket, due to the unreasonable formula design, frosting is very easy to occur, that is, the phenomenon that the liquid or solid compound in the formula migrates from the inside of the rubber to the surface of the rubber, which not only affects the rubber gasket. The service life of the tablet, and it is easy to contaminate the medicine, affecting the treatment and even health of the patient
In addition, the rubber gasket made of the existing formula has poor resilience, and it is prone to leakage of the needle when the infusion bottle is punctured.

Abstract

The invention discloses a frosting-free medicinal infusion rubber gasket which is prepared from the following materials in parts by weight: 60-90 parts of isoprene rubber, 10-30 parts of isoprene rubber, 5-20 parts of butadiene rubber, 10-40 parts of calcined kaolin, 5-30 parts of white carbon black, 1-10 parts of zinc oxide, 1-10 parts of stearic acid, 1-10 parts of white oil, 1-10 parts of anti-aging agent, 1-10 parts of coupling agent, 1-10 parts of ozone-resistant wax, 1-4 parts of accelerant and 0.1-1 part of vulcanizing agent. The frosting-free medicinal infusion rubber gasket has good rebound resilience and does not have frosting trouble, so that the problems of liquid leakage and contamination of liquid medicine are solved when the frosting-free medicinal infusion rubber gasket is used for infusion bottle piercing and dosing, the treatment quality on patients is improved, and the service life of the rubber gasket is prolonged.

Description

technical field [0001] The invention relates to a medical transfusion rubber gasket. Background technique [0002] With the increasing level of medical care, people have higher requirements for medical quality, and therapeutic or supplementary infusion is the most widely used medical product in medical institutions. The most critical component in the use process is the rubber elastic gasket. Then, during the production and storage of the rubber gasket, due to the unreasonable formula design, frosting is very easy to occur, that is, the phenomenon that the liquid or solid compound in the formula migrates from the inside of the rubber to the surface of the rubber, which not only affects the rubber gasket. The service life of the tablet, and it is easy to contaminate the medicine, affecting the treatment and even health of the patient. In addition, the rubber gasket made of the existing formula has poor resilience, and it is easy to cause leakage of the needle when the infusio...
