A device and method for rapidly preparing medical drug-loaded non-woven fabrics

Abstract

The invention discloses a device and method for fast preparing medical drug-loaded non-woven fabrics. The device mainly comprises a spray-head assembly, an air compressor, an airflow distribution valve, a liquid storage tank and airflow tubes, wherein the spray-head assembly is composed of an airflow adapter, a shunt piece, a charging barrel, a heating ring and a temperature sensor. The spray-head assembly is connected with the air compressor, the airflow distribution valve and the liquid storage tank through the airflow tubes. The connection mode of the spray-head assembly is that the airflow adapter, the shunt piece and the charging barrel are threadedly connected with each other in a coaxial mode from inside to outside, and the heating ring and the temperature sensor are matched with each other to conduct heating and temperature measuring respectively on the charging barrel; a polymer melt feeding hole and a micro-airflow inlet are formed in the vertical side face of the charging barrel. According to the method for fast preparing the medical drug-loaded non-woven fabrics, a melt-blow mode is utilized, so that blowing and drawing are conducted on polymer melt through high speed airflow which carries medicament droplets, the drug-loaded non-woven fabrics is formed, and topical application of drug is conducted on a wound directly; gaps are adjusted through rotating, and the drug-loaded non-woven fabrics is finally formed; the non-woven fabrics is loaded with drugs through the mode that the high speed airflow passes through the medical liquid and carries the medicament droplets.

Description

technical field [0001] The invention relates to a device and method for rapidly preparing a medical drug-carrying nonwoven fabric, and belongs to the field of medical devices. Background technique [0002] At present, the medical dressings commonly used in the medical field are mostly plant fiber cloths, which must be treated or disinfected with drugs. When dressing, the uniformity of the drug application cannot be well guaranteed. Because the wound is not a flat surface, the dressing may not fully fit the wound, resulting in slower wound healing or further worsening of infection. [0003] In addition, for sudden large-scale disasters that cause people to be injured, treatment such as disinfection must be carried out at the first time, otherwise many complications such as wound infection will be caused, so the dressing of the wound must be fast, and the traditional gauze Bandaging does not meet the needs of this particular case. SUMMARY OF THE INVENTION [0004] In order...

AI Technical Summary

Problems solved by technology

[0002] At present, most of the medical dressings commonly used in the medical field are plant fiber cloth, which must be treated or disinfected with drugs. When bandaging, the uniformity of drug application cannot be guaranteed.

Since the wound is not a flat surface, the dressing may not be able to fully fit the wound, resulting in slower wound healing or further infection

[0003] In addition, for a sudden large-scale disaster that causes people to be injured, it is necessary to carry out disinfection and other treatment as soon as possible, otherwise it will cause many complications such as wound infection, so the wound dressing must be fast, and the traditional gauze Bandaging does not meet the needs in this particular case
