Abstract

The invention provides a blood transfusion latex pipe and a preparation method thereof. The blood transfusion rubber pipe is composed of the following raw materials in parts by weight: 30 to 50 parts of natural latex, 40 to 60 parts of plant fiber, 0.5 to 1.2 parts of sulfur, 0.5 to 1 part of sodium pyrophosphate, 0.8 to 1.5 parts of polyvinyl methyl ether, 0.5 to 1.3 parts of ammonium oleate soap, 1 to 2 parts of potassium laurate, and 3 to 10 parts of Arabic resin. The provided blood transfusion latex pipe has the advantages of large tensile strength, high break elongation rate, and good thermal stability and mechanical stability, and can be applied to milk steaming, boiling, and disinfection for many times.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a blood transfusion rubber tube and a preparation method thereof. Background technique [0002] Medical hose is a tubular rubber product used for medical treatment. It can be divided into two types: external use and internal use. The former is used for various gas and liquid transportation, such as stethoscope hose, infusion hose, etc.; the latter is commonly known as medical rubber catheter, and can be divided into single-lumen tube and multi-lumen tube according to the structure. The rubber catheter is a rubber tube inserted into the body's cavity and blood vessel, and is used to inject medicine or extract body fluid and determine the opening degree of the lumen. Medical hoses require smooth surfaces, non-toxic, odorless, and disinfection-resistant. In particular, hoses for internal use must be guaranteed to contain no harmful soluble substances (such as lead, cadmium, arseni...
