潰瘍においては、自然治癒することができない。2. Description of the Related Art A wound is a tissue that is divided or destroyed.
It is defined as a condition that has more or less tissue loss and causes a corresponding dysfunction. Wounds generally undergo healing, clotting, inflammation, tissue renewal, and the like, before healing. The relatively small injury results in spontaneous healing, but the large injury and intractable ulcer such as diabetic ulcer and pressure ulcer cannot heal spontaneously.

法もないままに放置されているのが現状である。Particularly in recent years, the number of bedridden elderly people has increased with the aging society, and the number of patients suffering from intractable pressure ulcers and skin ulcers due to bed sores has continued to increase. Therapeutic agents (materials) are on sale. However, there is no definitive treatment, and many are left without any appropriate treatment.

た。[0004] Surgical treatment using flaps and the like is the most effective means for pressure sores and skin ulcers of deep wounds of degree III or higher, but it is often impossible due to the underlying disease and the like. For a long time, gauze coated with an ointment has been applied to the affected area, and conservative ointment treatment has been performed, which is changed daily. In addition, wounds tend to heal more quickly in a moist environment because granulation and epithelium formation tend to occur, so the hydrocolloid containing a polymer such as sodium alginate or carboxymethylcellulose for the purpose of keeping the wound moist is the main component. Dressing materials have been developed, and closed therapies using synthetic materials have been used in clinical settings.

結果、創傷治癒が著しく阻害されることになる。[0005] However, even if such a material is used, a good therapeutic effect is often not obtained, and the material often becomes intractable. One of the factors is the deterioration of tissue due to poor blood circulation in the wound, etc., resulting in a decrease in secretion and activity of physiologically active substances such as angiogenic factors and growth factors necessary for wound healing, and angiogenesis and granulation. The lack of a sufficient environment for the renewal of the tissue is mentioned. Another factor is poor blood circulation at the wound site, which makes it impossible to resist bacterial infection, which results in a significant impairment of wound healing.

Aggressive treatments that promote wound activity have been attempted. However, the problem with these materials is that they are very expensive and are not resistant to bacterial infections, so poor control of the infection may rather exacerbate the wound.

開示されている（特表平10-504484号）。[0007] Therefore, in the treatment of wounds, particularly the treatment of intractable wounds, it is desired to develop a technique for controlling bacterial infection, promoting the activity of the wounds, and providing an environment suitable for promoting wound healing. . As such, good wound blood circulation has enormous significance for the process of repair and regeneration of wound healing. As a means for solving the above-mentioned problems, an apparatus and a method for treating a wound by applying reduced pressure to the wound (Japanese Patent Publication No. 9-503923) are disclosed. It has been shown that applying a reduced pressure to a wound for a certain period of time promotes healing of the wound as a result of promoting blood flow to the wound area and also reduces bacterial density in the wound. In another invention, there is disclosed an invention relating to a device for closing a wound which improves this technology, is easy to use, is compact, has excellent storability, and can be executed effectively and economically advantageously.

The number of bacteria can be reduced. However, these prior arts do not have a contrivance to continuously wash the wound surface, so the effect of reducing the number of bacteria is poor, and even if a negative pressure application operation is performed daily, the number of bacteria decreases to about 1/2 after one week. It does not actively clean the wound surface and remove bacteria. In the process of wound healing, how to clean the wound surface, in other words, how to control the infection, plays a role in the subsequent healing. Antibacterial agents and antibacterial materials are used to control infection on the wound surface.However, abuse is not desirable due to problems such as the effect on the host and the emergence of resistant bacteria. It is desirable to clean the wound surface by removing bacteria and the like. Even at present, in the treatment of wounds, particularly for pressure ulcers and the like with infection, the operation of cleaning the wound surface by eating raw food or the like is essential. It has long been practiced to apply a pus basin to the affected area and squirt a saline solution onto the wound surface to wash it.However, it is not possible to collect the lavage solution well in the pus basin, and there is a risk of secondary infection by the cleaning solution. There is a fear.

The drain outlet and the suction means can be connected via a hose or a tube. Further, a collecting means capable of trapping exudate and washing waste liquid may be provided between the drain outlet and the suction means. The collecting means can be provided with a function to stop the suction means in case the trapping capacity is exceeded by an excessive amount of exudate or washing drainage. Further, it is more desirable that the collecting means be a material that can be removed and disposed of to prevent contamination. Further, the suction means may be used in combination with a number of commercially available portable closed suction type drain devices. Further, a mechanism such as a check valve can be provided so that the discharged liquid sucked between the wound surface cover and the suction means does not return to the wound surface. The provision of a stopcock in the process of connecting the outlet to the tube is one of the features of the present invention. Thus, after the space between the wound surface cover and the wound surface is made to have a negative pressure by using the suction means, by operating the stopcock, the negative pressure state can be maintained even when the suction means is disconnected. Therefore, the treatment can be performed even when only the wound surface cover from which the tube or the like is removed is attached, and the freedom of the patient is not restricted and the burden is reduced. The type of stopcock is not particularly limited as long as it can shut off the wound surface cover and the suction means, but a two-way stopcock or a three-way stopcock is desirable from the viewpoint of operability.

る。On the other hand, in order to continuously wash the wound surface in a state where the wound surface cover is in close contact with the wound surface, which is another feature of the present invention, the wound surface cover may be provided with a cleaning liquid inlet. A cleaning liquid unit is connected to this. The irrigation liquid inlet can be provided at any position, but it is desirable that the wound surface cover be on the diagonal line of the outlet from the viewpoint of the efficiency of cleaning the wound surface. In the case of a conical hard cup shape, a shower-like nozzle is provided at the top, so that the cleaning liquid is spouted over the entire wound surface, which is desirable from the viewpoint of the cleaning effect. The cleaning liquid inlet and the cleaning liquid unit can be connected via a hose or a tube. Further, it is one of the features of the present invention to provide a stopcock in the process of connecting the cleaning liquid inlet and the tube. By operating the stopcock in a state where the space between the wound surface cover and the wound surface is set to a negative pressure by using the suction means, the cleaning liquid is spouted from the cleaning liquid unit through the inlet, and the wound surface cover is wound. The wound surface can be continuously washed while being in close contact with the surface. The washing solution used for washing is not particularly limited as long as it does not significantly affect the wound surface when the wound surface is washed, and examples thereof include physiological saline, acidic water, and a disinfectant. These washing liquids are put into a container such as a bag or a bottle and used as a washing liquid unit.
