Description

Visual negative pressure drainage dressing and negative pressure suction device Technical Field The utility model relates to the technical field of medical equipment, in particular to a visual negative pressure drainage dressing and a negative pressure suction device. Background Wounds, wound surfaces, wound cavities and the like caused by various primary diseases or operations are clinical common diseases, and at present, debridement and dressing change, various dressing coverage, negative pressure closed drainage technology (Vacuum SEALING DRAINAGE, VSD) and the like are still mainly used for treating burns and scalds and wound surfaces. Among them, VSD technology is one of the main stream treatment technologies for the treatment of wound surfaces difficult to heal, and is widely used and achieves better curative effects. VSD technology (traditional wound negative pressure treatment technology) is currently widely used worldwide, however, currently known VSD technology (traditional wound negative pressure treatment technology) has the defects that a foam drainage material covering a wound surface is separated from a medical adhesive film sealing the wound surface, and a doctor nurse covers the wound surface with the foam drainage material and then seals the adhesive film. The sealing of the larger wound surface is long in time consumption and even incomplete, so that air leakage and the like are caused when the electric negative pressure machine and the like are used for pumping. The long sealing time of the film can not only increase the medical workload, but also possibly influence the rescue treatment of patients. The VSD technology is difficult to install, takes a long time, and is used for changing the medicine once in 5-7 days in clinical routine. Because the negative pressure drainage dressing is opaque, a doctor cannot observe the change of the wound surface in real time, for example, after skin grafting, skin flap transfer and other operations, observe the blood circulation conditions of skin flaps and the like, and clinically face to be unable to evaluate the change of the wound surface and switch the treatment method of the wound surface in time. The VSD technology is connected with negative pressure machines and the like to attract drainage treatment, can only adjust the magnitude of negative pressure value of wound surface treatment, has single function, and does not accord with the development direction of wound surface treatment digitization. None of the above problems of VSD technology currently has a suitable solution and technical product.
