Problems solved by technology
[0008] Aiming at the deficiencies of the prior art, the present invention provides a bio-protective wound film production storage, which solves the relatively strict storage environment requirements of the current bio-protective wound film. When the traditional storage is fed, bacteria will be carried into the storage, and the activity of the biofilm will be reduced. will be relatively reduced, so that the growth firmness of the biofilm on the wound carrier will be reduced, and at the same time, the bacteria on the writing tape will also cause secondary pollution to the wound carrier

The invention discloses a storage device for production of biological wound-protecting films, and relates to the technical field of biological films. The storage device comprises a bottom plate; an external safety sealing mechanism is arranged on the outer portion of a threaded seal opening; an automatic exhaust mechanism is fixedly connected to the top ends of an inner storage frame and an outerframe and located on the right side of a feed pipe; an internal extension pipe is communicated to one end, located in the inner storage frame, of the feed pipe; an inner floating plate is fixedly connected at a position between moving sliders; a movable slot is fixedly connected to the middle position of the inner floating plate, and an oxygen consumption layer is fixedly connected to the upper surface of the inner floating plate. The storage device for the production of the biological wound-protecting films has the advantages that the sealing effect at the joint is improved, external bacteriaare prevented from being brought into the storage device, the internal oxygen content of the storage device is reduced, the aerobic activity of the biological wound-protecting films during storage islowered, the effectiveness in use of the biological wound-protecting films is improved, the activity of the biological wound-protecting films is decreased in a low temperature environment, and the mortality of bacterial flora in the biological wound-protecting films is reduced.
Description
technical field [0001] The invention relates to the technical field of biological membranes, in particular to a production storage device for biological wound protection membranes. Background technique [0002] Biofilm, also known as biofilm, refers to an organized group of bacteria attached to the surface of living or inanimate objects and wrapped by bacterial extracellular macromolecules. Biofilm bacteria are highly resistant to antibiotics and host immune defense mechanisms. There are various major biological macromolecules such as protein, polysaccharide, DNA, RNA, peptidoglycan, lipid and phospholipid in the biofilm. The formation of biofilm multicellular structures is a dynamic process, including stages of bacterial initial adhesion, biofilm development, and mature diffusion. [0003] The main chemical components of biofilms are lipids and proteins, followed by sugars, and there are also trace amounts of nucleic acids, metal ions and water. The proportions of membra...
