Manufacturing method for dressing and basement membrane thereof

Abstract

The embodiment of the invention discloses a manufacturing method for a dressing and a basement membrane thereof. The basement membrane is made of high polymer materials and includes a first zone and asecond zone. The first zone is composed mainly of a composite fiber network of a micron scale fiber network and a nano scale fiber network. The second zone is mainly composed of a micron scale fibernetwork. The dressing can adhere to skin without a layer of glue, maintains good adhesion in a liquid environment and has good gas permeability, thereby speeding up wound healing and preventing bacterial infection; and an observation window and in-situ detection of wound exudates are provided, moreover, the cost is low, and the use is environmentally friendly.

Description

technical field [0001] The present disclosure relates to a medical device and a manufacturing method thereof, in particular to a medical dressing and a manufacturing method thereof. Background technique [0002] Currently used medical dressings can be mainly divided into fabric dressings and plastic (resin-based) dressings. Fabric dressings, such as fabric band-aids, are not waterproof, and are not tightly sealed relative to the applied body parts, which is easy to cause wound infection; while plastic dressings, such as plastic film, are impermeable and airtight, and the wound will be damaged after a long time of use. Easy to suppurate and worsen. [0003] Usually, an adhesive layer needs to be set in the dressing to firmly adhere to the skin, but in a liquid environment, such as infiltration of body fluids, high humidity in the environment, etc., the adhesive force of the adhesive layer will be destroyed, causing the dressing to fall off. Moreover, sticking and tearing of...

AI Technical Summary

Problems solved by technology

Fabric dressings, such as fabric band-aids, are not waterproof, and are not tightly sealed relative to the applied body parts, which is easy to cause wound infection; while plastic dressings, such as plastic film, are impermeable and airtight, and the wound will be damaged after a long time of use. Easy to suppurate and worsen

[0003] Usually, an adhesive layer needs to be set in the dressing to firmly adhere to the skin, but in a liquid environment, such as infiltration of body fluids, high humidity in the environment, etc., the adhesive force of the adhesive layer will be destroyed, causing the dressing to fall off. And the sticking and tearing of the adhesive layer relative to the skin will bring discomfort to the user.

[0004] At present, although some antibacterial drugs are tried to be introduced into medical dressings, the material of the dressing is not good for the adsorption of antibacterial drugs, and the antibacterial drugs are easy to fall and spread into the environment, and are ingested by the human body to affect health. Not only is the drug wasted, but it may also lead to bacterial mass infection and worsen the wound

[0005] In addition, currently used medical dressings usually cover or cover the wound, and the medical staff or other users cannot determine the positioning of the dressing relative to the wound when applying the dressing, resulting in misalignment, resulting in the area of ​​the wound being covered. Inadequately coated conditions where the dressing is applied to normal surrounding tissue that does not require coating, resulting in less effective dressing application

Furthermore, since the wound is wrapped, it is impossible to check the wound healing status conveniently. In order to check and confirm the condition of the wound, the medical staff or other users need to repeatedly open the dressing and reapply it, which is easy to pull the wound and affect its recovery
