A kind of medical coconut fruit additive-free membrane and its production process

Abstract

The invention relates to the field of medical dressings and in particular relates to a medical coconut fruit additive-free membrane and a production process thereof. A raw material coconut fruit membrane is treated with strong alkali NaOH by sections and weak acid, namely citric acid, is used for neutralizing; an obtained semi-finished coconut fruit membrane is washed through ultrasonic oscillation and sterilized through ozone water; the membrane is packaged in a reasonable manner and is subjected to sterilization and disinfection treatment in high-temperature and high-pressure, and irradiation manners, so as to obtain a wound covering membrane which has a clean appearance, wherein a microcosmic reticular fiber structure and a membrane overall appearance texture of the wound covering membrane meet medical-grade requirements; the microcosmic reticular fiber structure forms small pores and can effectively prevent external bacteria from invasion; in a utilization process, medical liquid can be effectively locked and water and the medical liquid are prevented from being lost so that acting time of effective components on skins is prolonged; a drug administration effect is gentle and the irritation on wounds can be effectively reduced; the membrane has a certain absorption effect on tissue liquid of the wounds and has an excellent skin-friendly property; the production process is further simplified, is easy to operate and is suitable for large-batch rapid production.

Description

technical field [0001] The invention relates to the field of medical dressings, in particular to a medical coconut-free film sheet and a production process thereof. Background technique [0002] The applicant discloses a production process of medical nata de coco without additive membrane through CN201310290423.7, and the invention uses the technological skill of CN201110456690.8 disclosed by the applicant, on the basis of the obtained semi-finished coconut without additive membrane, After being sterilized and disinfected in a high-temperature and high-pressure furnace, secondary sterilization by irradiation is carried out, and finally ultrasonic disinfection is used to obtain medical coconuts without added diaphragms. This product has the advantages of energy saving, high processing efficiency, and no chemical drug residues, and the diaphragm is guaranteed The microbial fiber material and its skin-friendly properties. Suitable for use as wound medical grade diaphragms. ...

AI Technical Summary

Problems solved by technology

[0003] In the production process of the semi-finished product of CN201110456690.8, it is necessary to adopt the process of rehydrating acid washing, cooking, freezing, ozone disinfection, electroporation, microwave disinfection, refreezing, electrophoresis, and soaking in water to obtain the semi-finished coconut film, and the process is relatively complicated. It is cumbersome, there are many key control points in the production process, and there are certain deficiencies in maintaining the microscopic network fiber structure of the coconut film and the overall appearance texture of the film through multiple temperature-changing and electric treatment processes, which are suitable for Used as a localized wound covering film or mask care, there is room for improvement in the production of medical covering materials for large-area wounds
