Problems solved by technology

[0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used on the human body. When treating patients, multi-purpose medical devices are commonly used, and In order to avoid cross-infection, many disposable medical devices are used, such as disposable catheters, infusion bags, gloves, etc., but these existing disposable medical devices are mostly plastic products, and they are not degradable, which will cause a lot of white pollution. Cleaning inconvenient

Embodiment 1

[0022] A degradable medical device, its raw materials include the following components by weight: 60 parts of plastic raw materials, 10 parts of cellulose, 6 parts of starch, 3 parts of chitosan, 2 parts of polyglucosamine, 3 parts of animal glue, photosensitizer 1 serving.

[0023] The present invention also provides a production process for degradable medical devices: comprising the following steps:

[0024] 1) Plastic recycling: Recycling degradable plastics, selecting plastic products that can be recycled, and placing non-recyclable plastics in an environment suitable for plastic degradation for degradation;

[0025] 2) Plastic purification: Disinfect and clean the selected degradable plastics, first use cleaning solution for 2 times, then use disinfectant solution for 1 time, and finally use clean water for 2 times, and use a dryer to dry the sterilized plastic Dry degradable plastics for drying. The temperature during drying is 70°C, and the drying time is 1 hour. Durin...

Abstract

The invention discloses a production process of degradable medical instruments. The degradable medical instruments are prepared from the following components in parts by weight: 60 to 80 parts of plastic raw materials, 10 to 16 parts of cellulose, 6 to 9 parts of starch, 3 to 6 parts of chitosan, 2 to 5 parts of poly-glucosamine, 3 to 6 parts of animal adhesives and 1 to 2 parts of photosensitizer. The invention also provides the production process of the degradable medical instruments. The production process comprises the following steps: recycling plastics, specially, recycling degradable plastics and picking out recyclable plastic products and putting the plastics which cannot be recycled in an environment suitable for enabling the plastics to be degraded; purifying the plastics. According to the production process of the degradable medical instruments disclosed by the invention, degradable waste plastics are used as main raw materials, so that the degradable waste plastics are reasonably recycled; moreover, the production process of the degradable medical instruments has the advantages that the raw materials are easily obtained, the preparation method is simple, white pollutionis reduced, energy conservation and environmental protection are realized, and meanwhile, the used medical instruments are conveniently treated, so that the manpower and material resources are reduced.
