Abstract
The utility model relates to a wound paste which utilizes a negative-pressure suction device to fix wounds and the like after a surgical operation. The product is composed of a wound joint face, a negative-pressure air chamber, a one-way air valve and a pumping hole. The wound joint face is fixed on a wound, a germless injector is connected with the pumping hole to pump the air out until the joint face is tightly jointed with the skin around the wound; the negative-pressure air chamber sinks and maintains in a highly negative pressure state, and then the one-way air valve is closed to prevent reversed flow of the air; a double annular bothrium and densely-distributed millimeter sucking discs at the bottom and the negative-pressure air chamber are connected through a capillary channel; and the wound and the peripheral skin thereof can be tightly absorbed and fixed by utilizing the double annular bothrium and the millimeter sucking discs at the bottom of the negative pressure. The utility model provides a favorable condition for healing up the wound, and is a medical article which can partially substitute the traditional needle seaming after the operation. The utility model can absorb the transudate of the wound.
Description
Affiliated technical field
Relate to a kind of bandage, apply to the cleaning wound behind the medical operating, can partly substitute a kind of medical supplies that traditional postoperative needlework are sewed up.This utility model utilizes the negative-pressure adsorption device to fix the smooth wound of postoperative cleaning, reduces postoperative scar and forms, and promotes wound healing.This utility model also has the function of absorbing wound fluid.
Background technology
At present, known traditional surgery adopts needlework suture operation otch, often stays the stitching cicatrix of " Scolopendra " shape behind the wound healing, influences the operative site skin beauty greatly.How to handle wound fluid in addition and also be wherein hang-up.
Summary of the invention
Influence this problem of operative site skin beauty in order to overcome the stitching cicatrix that stays " Scolopendra " shape after existing surgical postoperative conventional needle suturing with thread management operative incision heals, this utility model utilization vacuum suction principle is made negative-pressure wound plaster, can fixedly secure surgical wound, part substitutes traditional postoperative wound and sews up, reduce the area and the size of cicatrix, promote wound healing.Drawing liquid of the present utility model and vacuum suction function can be used for absorbing the transudate of wound.
The technical scheme that its technical problem that solves this utility model adopts is:
This utility model mainly is made up of wound binding face and negative pressure chamber device two parts, product is mainly made by the transparent medical polymer material, transparent material is to observe the wound healing situation for convenience, binding face is by having the viscous force coating that the antibacterial-anti-inflammatory drug nano material constitutes, it can make wound binding face and skin good combination, and prevent wound infection, dual annular bothrium in bottom and the millimeter sucker that gathers are connected with high-tension negative pressure chamber device by capillary tube, the negative pressure chamber device forms the height negative pressure state after the connection asepsis injector deflates, dual annular bothrium and the millimeter sucker that gathers can fixedly secure and airtight firmly wound and surrounding skin thereof, for wound healing creates favorable conditions.The negative pressure chamber device partly has valve structure, stops gas backstreaming, and the negative pressure chamber device can be with wound fluid negative suction gas cell device, and keeps veneer suction with negative pressure.Another QI KOU cecum is cut off with shears finishing using, and healing is pasted take off smoothly.
The beneficial effects of the utility model are,
Can fixedly secure surgical wound, part substitutes traditional postoperative wound and sews up, and reduces the area and the size of cicatrix.The utlity model has the function of the transudate of absorbing wound.

The specific embodiment
Product is by wound binding face (7), negative pressure chamber device (5) Non-return air valve (4), bleeding point (2) is formed, product is mainly made by the transparent medical polymer material, can observe the wound healing situation at any time, wound binding face (7) surface is to constitute viscous force coating (8) by containing the anti-inflammation drugs nano anti-biotic material, can make wound binding face (7) and wound and surrounding skin good combination thereof, negative pressure chamber device (5) is connected by capillary channel (6) with a dual annular bothrium in bottom (10) and a densely covered millimeter sucker (11), dual annular bothrium in bottom (10) and the millimeter sucker (11) that gathers can paste healing and fixedly secure in wound circumference, can stop pathogen to enter wound by airtight wound.Negative pressure chamber device one end is Non-return air valve (4), valve structure (3) can stop gas backstreaming at the negative pressure closure state, the top of negative pressure chamber device (5) has very strong back stretch, can keep negative pressure chamber device (5) inner height negative pressure, and wound fluid negative suction gas cell device (5) can be extracted out transudate with asepsis injector (12).QI KOU cecum (1) is cut off with shears finishing using, and negative-pressure wound plaster is taken off smoothly.
Clean wound before using earlier and keep wound surrounding skin drying, choose the product that is fit to the otch specification, from preventing that being stained with gummed paper (9) takes bandage off, prolongs with hands and vertically tightens surgical wound, be attached on the wound negative-pressure wound plaster is smooth, and guarantee that bandage and wound and surrounding skin thereof combine closely.Connecting bleeding point (2) with asepsis injector (12) extracts gas out, be close to the wound surrounding skin until veneer, top negative pressure chamber device (5) subsides and keeps height and can pull out asepsis injector (12) during negative pressure state, the back valve structure (3) of bleeding is closed to stop gas backstreaming (failing neat fit or the top air chamber can't be kept the negative-pressure wound plaster that negative pressure should renew as wound surface), keep close observation, as find to have in the air chamber transudate in time to extract out, and keep negative pressure chamber device (5) height negative pressure state.Use and cut off QI KOU cecum (1) with shears after 3-5 days and negative-pressure wound plaster can be removed, the negative-pressure wound plaster that more renews behind the clean wound is until wound healing.And guarantee that wound is not drawn back by external force.
Application notice: 1. use this product to need in strict accordance with surgery sterile working program.2. must clean wound surface before using, avoid the water contact in the use, please don't catch after the opening and touch the middle medicine heart.3. the skin allergy person stops using.4. to this product allergy sufferers forbidding, the careful usefulness of allergic constitution person.5. when this product character changes or when gas leakage packing ban use of.6. non-cleaning wound must not use.
