Manufacturing method for production process of medical latex gloves

- Aug 07, 2020-

Background technique:

Medical latex gloves are essential medical supplies for surgeons. They have barrier isolation properties and good film strength. The higher elasticity of medical latex gloves gives it better gripping performance and shape conformability. This feature cannot be replaced by any other material, and it is also the main reason why medical latex gloves are still used as surgical medical supplies at home and abroad.

Medical latex gloves are essential medical supplies for surgery. Although they have the characteristics that other materials cannot be replaced, they also have some problems. For example, natural latex gloves protein causes human allergies, and glove powder acts as a vehicle for transmitting latex protein or infecting bacteria. , Has been increasingly regarded as a potential danger by the medical profession. There are two naturally occurring forms of protein in latex. One is a water-soluble protein, and the other is a "linked" protein that is bonded to rubber molecules. This part of the protein is non-extractable. Soluble protein is one of the main allergens that cause human allergies. The proportion of people who use natural latex gloves is as high as 12.5%, of which 2.5% have allergic symptoms, and 10% produce antibodies in the blood.

Summary of the invention

 In view of the above situation, the purpose of the present invention is to provide a production process of low-protein medical latex gloves, so as to effectively prevent people who use natural latex gloves from infection and allergies and protect their health. The purpose of the present invention is to realize that the rinsed model undergoes a constant temperature, soaks the coagulant, and the coagulant is dried at a certain temperature, the latex is impregnated, after the wet film is shaped, it is leached and dried in a drying box. , According to the specifications, the edges are painted and curled, dried and cured again, soaked in hot water. In order to prevent adhesion, the gloves are dipped in release agent to take off the gloves from the model. The characteristic is that the product is stripped with borax, ammonia and water For protein extraction solution, stir the gloves at 60-75°C for 2 hours, then lower to room temperature to soak for 18 hours, change to clean water and wash for 15-30 minutes, boil the vulcanized powder mixture, dehydrate and cool.

The technical effect of the present invention is that the protein content of the glove is greatly reduced, which can be reduced by 55.8%, and the residual soluble protein mass fraction is less than IlOX 10_6 allergy critical index. Trials on allergies from multiple medical units have proved that the symptoms of most allergic people have been significantly improved, which can effectively prevent people who use natural latex gloves from getting allergic.

 A production process of medical latex gloves. The process is to pass the rinsed model through a fixed temperature, soak the coagulant, dry the coagulant at a certain temperature, impregnate the latex, after the wet film is shaped, pass through the leaching, in the drying box Dry and vulcanize in the middle, paint and curl the edges, dry and vulcanize again, soak in hot water. In order to prevent adhesion, the gloves are immersed in release agent to take off the gloves from the model. To deproteinize the extraction solution, stir the gloves at 60-75°C for 2 hours, lower to room temperature and soak for 18 hours, change the water to wash for 15-30 minutes, boil the vulcanized powder mixture, dehydrate and cool.

 Full text abstract

 The invention discloses a production process of low-protein rubber medical gloves. The technical feature of the process is that the gloves are basically the same as the prior art before the removal of the film, and the protein removal treatment is added after the removal of the film. The treatment method is to use borax, ammonia and water as the deproteinization extraction solution. Stir the gloves for 2 hours at 60-65°C, soak them at room temperature for 22 hours, change the water and wash for 20-30 minutes, boil the vulcanized powder, Throw water and air dry to cool. The addition of deproteinization treatment after demolition can greatly reduce the protein content of the glove, which can be reduced by 53.9%, and the residual soluble protein mass fraction is less than 110×10 allergy critical index. Trials on allergies from multiple medical units have proved that the symptoms of most allergic people have been significantly improved, which can effectively prevent people who use natural latex gloves from getting allergic.
