Medical dry or wet film with effusion seams

Abstract

The invention discloses a medical dry or wet film with effusion seams. The number of the effusion seams can be one or more, the effusion seams are through in the thickness direction of the film and the contour line of the effusion seams on a horizontal surface of the film is not of a closed shape. The invention further discloses a manufacturing method and applications of the dry or wet film. Compared with an existing medical film, the medical dry or wet film with the effusion seams can timely drain liquid effused from a wound out of the film through the through effusion seams with the thickness equal to the medical film when being used during time of wound dressing or wound bandaging so as to greatly reduce probability of bacterial infection, thereby quickening wound healing and meanwhile reducing number of times of dressing exchanges.

Description

technical field [0001] The present invention relates to the field of medical materials, specifically, the present invention relates to a medical film with seepage seams, which can be applied to large-area wound dressings, guided growth films, soft tissue patches, tissue engineering skin and health care masks, In wound dressing and other fields, especially when used as a wound dressing, the exudate produced by the wound covered inside the membrane can be discharged in time through the seepage seam provided on the membrane to avoid bacterial infection or suppuration. Background technique [0002] Bacterial cellulose (BC for short, or microbial cellulose), as a renewable multifunctional biomaterial, has attracted increasing attention in the research field and has shown broad application development prospects. Over the years, researchers at home and abroad have been studying BC. Due to its unique ultrastructure and physical and chemical properties, it has great advantages in th...

Problems solved by technology

[0003] At present, although various membranes are easy to obtain, no matter what type of membrane, there is a typical problem when used in the medical field, that is, when used during wound dressing or wound dressing, the wound will leak body fluids. It is difficult to discharge the membrane, which increases the chance of bacterial infection, and because of this, it is necessary to change the dressing manually, which increases the risk of wound infection
