This invention discloses a portable low-temperature plasma device based on a Laval nozzle structure and its application, belonging to the field of plasma technology application technology. Specifically, it includes (1) the construction of the device; and (2) the use of the device for fungal eradication treatment and transdermal drug delivery enhancement treatment. The beneficial effects achieved by this invention are as follows: This invention is the first to apply the Laval nozzle structure to a portable low-temperature plasma device. The results show that the device can effectively improve the plasma jet performance and active particle content, significantly improve the treatment effect of fungal infections of the skin and nails and the transdermal drug penetration efficiency, while solving the problems of large size, reliance on external power supply, and complex operation of traditional plasma devices. Therefore, using this invention for the treatment of fungal infections of the skin and nails and for enhanced transdermal drug delivery has advantages such as ease of operation, high safety, non-invasiveness, and high efficiency, and thus has potential application prospects in the field of skin disease treatment and transdermal drug delivery.

The utility model provides a light quick-drying garment material, and relates to the technical field of garment materials. Through the multi-layer structural design of the skin-friendly layer, the antibacterial layer, the water guide layer, the protective layer and the anti-static layer which are sequentially compounded from inside to outside, perfect combination of multiple functions is achieved, and the fabric has the remarkable beneficial effects that specifically, the skin-friendly layer is formed by blending cotton fibers and modal fibers, the surface is mercerized through alkali liquor, and the anti-static effect is good; the fabric is softer and more comfortable and has no irritation when being worn next to the skin; the antibacterial layer is formed by interweaving viscose fibers carrying silver ions and bamboo charcoal fibers, the growth of bacteria is effectively inhibited through the synergistic effect of the silver ions and the bamboo charcoal fibers, clothes are kept clean, and the health of a wearer is protected; the water guide layer adopts the double-rib weave woven by the special-shaped section polyester fibers and the spandex fibers, and the section of the fibers is Y-shaped, so that the water guide performance of the fabric is enhanced, sweat can be quickly diffused and evaporated, and clothes are kept dry and comfortable.

The present application provides a kind of polypeptide sustained-release hydrogel coating for preventing catheter urinary tract infection and its preparation method, the coating includes the adhesive bottom layer attached to the surface of catheter substrate, and the polypeptide sustained-release hydrogel functional layer compounded outside the adhesive bottom layer;The functional layer includes hydrophilic hydrogel gel-forming matrix, targeted antibacterial polypeptide, polypeptide sustained-release carrier and biocompatible auxiliary agent.The present application solves the interface bonding problem of hydrophobic catheter substrate and hydrophilic hydrogel through the adhesive bottom layer, the coating has strong adhesion, is resistant to urine immersion and rubbing;Through polypeptide sustained-release carrier, antibacterial polypeptide is released for 30 days, and there is no risk of burst release;The targeted antibacterial polypeptide used is specific to urinary tract infection pathogenic bacteria, has no drug resistance induction risk, has excellent biocompatibility, can effectively prevent catheter-related urinary tract infection caused by short-term and long-term indwelling catheter, the preparation process is simple and controllable, is suitable for large-scale production, and can be widely applied to antibacterial modification of urinary intervention medical devices.
