Abstract
The invention relates to a wound protection device for a negative pressure drainage wound surface restoration system, wherein the used technical solution is that the device comprises a sponge body and a drain tube; the device is characterized in that the drain tube is divided into a drain area, a suction area and a dredging medicine injection area; the suction area is provided with a plurality of holes; the drain tube passes through the sponge body; the suction area is arranged in the sponge body; the drain area and dredging medicine injection area respectively stretch out of two to ends of the sponge body; and the end part of the dredging medicine injection area is connected with a seal plug. The wound protection device for a negative pressure drainage wound surface restoration system is characterized in that the device is provided with a tube connector. The device is simple in structure, easy for the operation of blockage dredging and easy for medicine injection of the wound surface without causing secondary pollution to the wound surface.
Description
Technical field
The invention belongs to medical instruments field, relates to Orthopeadic Surgery or brothers' surgery particularly, be used for repairing soft tissue or skin injury negative pressure drainage wound repair system protect the wound device.
Background technology
At Orthopeadic Surgery or brothers' surgery, to large tracts of land soft tissue infection, damaged and downright bad, steel plate exposes, exposed bone, tendon exposed, and before open fracture companion soft tissue defects carries out prosthesis, need handle wound surface, traditional method is to adopt artificial method, every day, sterilization was changed dressings to wound surface, change dressings so each time and all can bring huge misery to the patient, medical personnel's difficult treatment also can cause the secondary pollution of wound surface.Therefore initiated the negative pressure drainage technology in 1992 by German ULM doctor Fleischman of university.The negative-pressure sealed drainage technology is meant with the wound surface that protects traumatic material filling body skin or soft tissue defects, infection, the formation of downright bad back, serves as the intermediary between wound surface and the drainage tube, and traditional point-like drain is become comprehensive drain; With medical transparent membrane is the total enclosing material, cover, seal whole wound surface and lacuna, simultaneously drainage tube is connected with negative pressure source, make whole and protect the contacted wound surface of traumatic material to be in a complete surperficial closed negative pressure drainage state, organize in time and excrete to promote sepage, liquefaction and necrosis in wound surface, the lacuna; Infection chance between isolated wound surface and the external environment; To plaing a part to try to help the shoot grow by pulling it upward, accelerate the evenly growth fitly of granulation tissue of wound surface with the blood capillary that protects under the traumatic material contact surface; Hold back and close wound surface and lacuna.
But existing structure of protecting traumatic material just will have porous drainage tube to be inserted in the spongy body, one end of drainage tube is enclosed in the spongy body, the other end stretches out spongy body and is connected with negative pressure source, the problem that this structure exists is: the sepage of wound surface or liquefaction and necrosis are organized under the suction function of negative pressure source, enter in the drainage tube by the hole of spongy body and the hole of drainage tube, in case drainage tube is stopped up, there is not good solution: 1. or by obstruction place of re-injection soaked with liquid, cause secondary pollution but can make the sepage that entered drainage tube or liquefaction and necrosis tissue reenter wound surface simultaneously yet; 2. stop up in the time of to get rid of, can only change a complete set of product, cause the medical treatment cost height and bring misery to the patient; 3. have again, wound surface is injected medicine, also can only inject by the opening by drainage tube, equally also can make the sepage that entered drainage tube or liquefaction and necrosis tissue reenter wound surface and cause secondary pollution as needs.
Summary of the invention
In order to overcome the above problems, it is a kind of simple in structure that the invention provides, and processing ease is stopped up in mediation, and is easy to the wound surface injection, can not cause the negative pressure drainage wound repair system of secondary pollution with protecting the wound device to wound surface.
The invention is achieved by the following technical solution: negative pressure drainage wound repair system is with protecting the wound device, comprise spongy body and drainage tube, it is characterized in that: drainage tube is divided into drain district, suction zone and mediation injection district, suction zone is provided with some holes, drainage tube passes spongy body, suction zone places in the spongy body, the two ends that spongy body is stretched out in drain district and mediation injection district respectively, and the end in mediation injection district connects seal plug.
Above-mentioned negative pressure drainage wound repair system is characterized in that being provided with scraper with protecting the wound device.
The beneficial effect of the invention is: the invention is owing to be divided into drain district, suction zone and mediation injection district three parts with drainage tube, and suction zone places in the spongy body, the two ends that spongy body is stretched out in drain district and mediation injection district respectively, and dredging the end connection seal plug in injection district.Therefore in the effect of wound surface being carried out can reaching fully in the negative pressure drainage process sealing.In case drainage tube stops up plug is opened, inject liquid tamper is gone out by the drain district, also sepage or liquefaction and necrosis tissue are gone out simultaneously.Stop up weak effect as liquid handling, also can scraper be inserted in the drainage tube, directly block part is led to and open by mediation injection district; As needs wound surface is injected medicine, same by dredging the injection district to the wound surface injection.No matter as seen be to stop up or the injection medicine, all pass through mediation injection district but not process drain district, therefore the sepage or the liquefaction and necrosis tissue that will enter in the drainage tube can not reentered wound surface, cause secondary pollution.When the invention blockage problem occurred when drainage tube, medical personnel can conveniently handle, and had also reduced expense required when the patient needs to change because of drainage tube stops up in the time of for patient's relieving the pain caused by diseases with painful.

The specific embodiment
As Fig. 1～shown in Figure 4, negative pressure drainage wound repair system is with protecting the wound device: by spongy body (1), drainage tube (2) and scraper (4) constitute.
Drainage tube (2) is divided into drain district (2-1), suction zone (2-2) and mediation injection district (2-3), suction zone (2-2) is provided with some holes (2-4), drainage tube (2) passes spongy body (1), suction zone (2-2) places in the spongy body (1), the two ends of spongy body (1) are stretched out in drain district (2-1) and mediation injection district (2-3) respectively, and the end in mediation injection district (2-3) connects seal plug (3).
In case of necessity, scraper (4) inserts the drainage tube (2) from the end in mediation injection district (3-3).
Claims (2)
1. negative pressure drainage wound repair system is with protecting the wound device, comprise spongy body (1) and drainage tube (2), it is characterized in that: drainage tube (2) is divided into drain district (2-1), suction zone (2-2) and mediation injection district (2-3), suction zone (2-2) is provided with some holes (2-4), drainage tube (2) passes spongy body (1), suction zone (2-2) places in the spongy body (1), the two ends of spongy body (1) are stretched out in drain district (2-1) and mediation injection district (2-3) respectively, and the end in mediation injection district (2-3) connects seal plug (3).
