Problems solved by technology

[0003] The catheter bag includes a urine collection bag and a catheter, and the catheter is mostly a soft and bendable rubber tube for the convenience of the catheter bag. The urine bag catheter is repeatedly bent, and the traditional catheter material may break during the repeated bending process, which may easily cause urine leakage. However, there are many infectious disease patients in the hospital, and the rupture of the urine bag catheter may easily cause the spread of bacteria , so improving the toughness of the urine bag catheter is the research direction of traditional Chinese medicine at this stage

Abstract

The invention provides a resin material for a high-toughness urine bag catheter, and a preparation method thereof, and relates to the technical field of urethral catheterization bag processing, wherein the resin material is prepared from the following raw materials by weight: 45-55 parts of a PVC resin, 18-22 parts of polyformaldehyde, 4-8 parts of polyphenylene sulfide, 10-12 parts of polycarbonate, 6-8 parts of carboxylated nitrile rubber, 1-3 parts of nanometer dilanthanum trioxide, 2-3 parts of hydroxyapatite, 1-1.8 parts of 1,2-dimethoxybenzene, 4-6 parts of maleic anhydride, 2-2.5 partsof N,N'-di-tert-butylethylenediamine, 3-5 parts of benzoguanamine, 1-1.2 parts of a vulcanizing agent, 1-2 parts of an antioxidant, and 1-1.8 parts of a dispersing agent. According to the present invention, the deficiencies in the prior art are overcome, the toughness and the tensile strength of the resin material for the conventional urine bag catheter are improved, the embrittlement temperatureis reduced, the softness is increased so as to be conveniently used, and the method is suitable for popularization and production.

Description

Technical field [0001] The invention relates to the technical field of catheterization bag processing, in particular to a resin material for a high-toughness urine bag catheter and a preparation method thereof. Background technique [0002] Urinary catheterization bag is a device made of resin material to collect patient's urine through catheter. Indwelling catheterization is a common clinical operation method. It is important in the rescue of critically ill patients, neurogenic bladder function exercise, and urine output monitoring. significance. [0003] Urinary catheterization bags include urine collection bags and catheters. In order to facilitate the use of catheterization bags, catheters are mostly flexible and flexible rubber tubes. However, in order to reduce the footprint and ease of use during the use and storage of catheterization bags, they often The urine bag catheter is repeatedly bent, and the traditional catheter material may break during the repeated bending proce...
