Problems solved by technology

Yang Qing and others invented bandages, finger cots and their preparation methods for medical surgical fixation (CN200410016173.9). It is necessary to first make polycaprolactone on the outside and fibers on the inside, and melt and extrude them into composite fibers at the same time. The process is complicated

Embodiment 1

[0024] Embodiment 1: 80 grams of caprolactone-lactic acid copolyester with a molecular weight of 60,000 are dissolved in a mixed solvent of 800 grams of butyl acetate and 200 grams of tetrahydrofuran and heated for dissolution. After it becomes a uniform solution, 3 grams of zinc oxide are added, 5 grams of kaolin, 0.05 grams of phthalocyanine green were stirred and mixed evenly, and the polymer compound was coated on the cotton medical gauze by the roller transfer method. After compounding, 95% of the weight gain of gauze is resin coating.

Embodiment 2

[0025] Embodiment 2: 85 grams of polycaprolactone with a molecular weight of 80,000 are dissolved in a mixed solvent of 700 grams of ethyl acetate and 300 grams of tetrahydrofuran and heated for dissolution. After it becomes a uniform solution, 5 grams of zinc oxide and 4 grams of clay are added. 1 gram of titanium dioxide was stirred and mixed evenly, and the polymer compound was coated on the knitted polyester cloth by the roller transfer method. After the solvent volatilized, a white zinc oxide-containing thermal softening surgical fixation bandage was obtained. After coating, the knitted polyester cloth increased in weight by 105. % for resin coating.

Embodiment 3

[0026] Example 3: 60 grams of trans polyisoprene with a molecular weight of 60,000 was dissolved in 1000 grams of gasoline and heated for dissolution. After it became a uniform solution, 7 grams of zinc oxide and 0.06 grams of phthalocyanine blue were added and stirred evenly. The polymer composite is coated on the knitted acrylic fabric by the padding method. After the solvent evaporates, a blue zinc oxide-containing heat-softened surgical fixation bandage is obtained. After coating, the knitted acrylic fabric increases in weight by 85% to form a resin coating.

Abstract

A thermosoftening surgical bandage containing zinc oxide is prepared from fabric through dissolving the thermoplastic high-molecular composition containing zinc oxide in organic solvent, and coating it on said fabric as substrate.

Description

Technical field: [0001] The invention relates to a zinc oxide-containing thermal softening surgical fixation bandage and a manufacturing method thereof. Background technique: [0002] At present, most of the fixed bandages used in surgery are made of plaster materials. The disadvantages of plaster bandages are heavy weight, poor air permeability, inability to contact with water, and X-rays cannot pass through. Patients must remove the plaster bandages when doing X-ray examinations. Bring multiple inconveniences to patients. [0003] 随着科技的进步有不少专利报道了聚氨酯绷带,如CN89103828.0,CN 89103603.2,CN 90102934.3,CN 91100363.0,CN92108533.8,CN 94109580.0,CN 96103118.2,CN 96116321.6,CN99116091.6,CN 00132041.6,CN 01108791.9 patent. However, practically all polyurethane bandages have the disadvantages of short shelf life and easy contamination of patients and doctors during use, so these bandages are not used much in practice. [0004] There are constantly developing thermoplastic surgical fixa...
