Description

[Detailed description of the invention] Irrigation Note Wrap Obi The present invention relates to non-dressing for deep wounds. , this irrigated dressing has an adhesive and a plate that is substantially impermeable to air and liquids. This plate is used for supplying, suctioning and discharging liquid, and for pressure equalization. It has at least one hole.

In clinical treatment, deep wounds are often affected by infection, which negatively affects the healing process. This will prolong the patient's recuperation period. In fact, all non-emergency surgical procedures 2% of all emergency surgeries and 10% to 12% of all emergency surgeries. Concomitant infection. These patients received an additional 1500 ml per day for 4 to 7 days. It is difficult to treat these infections efficiently as medical treatment is required at the SEK cost. It is clear that the most important thing is to Pressure injury with injury to the patient's nerves (pressure 5ore) is often affected by infections. UK National Health Service Service (Brltish National Health 5 service) British Medical Service (British Medical 5ERVLC) e), which costs more than 908 million EK every year.

Current local medical treatments include removing dead tissue, cleaning and irrigation of the wound. consists of doing. These wounds were drained with a rubber drain and moistened with saline. Packed with gauze compress. Additional compresses are placed on top and covered with an adhesive bandage It will be done. Compress within the wound helps support the walls of the wound cavity and to some extent mobilizes the wound. prevent the patient from suffering and alleviate the patient's pain. Additionally, these compresses absorb fluid from wounds. and III/+, thus keeping the area surrounding the wound and wound clean. useful for. For small items, use foam rubber etc. as a filling material. Good. Such materials encourage the creation of a healthy wound surface. wound cavity Proper "packing" requires a very high level of professional skill. - For bandaging requires 15 to 30 minutes, which causes great pain to the patient. Furthermore, every Bandaging is required six to seven times a day. Large wounds require several compresses It is believed that if a single compress is left behind a wound, it can promote infection and damage the wound cavity. It makes it bigger.

For example, U.S. Pat. No. 3,753,439 describes A device for draining and irrigation without a band is disclosed. However, this conventional The technology device sometimes drains and cannot be used as a bandage. stomach. For example, West German Patent No. 2.809,828, U.S. Patent No. 3', 02B, 874 No. 3,874,387, U.S. Patent No. 2,280,91.5 discloses a device for irrigation of superficial wounds. Disclosed in these patents When using bandages, it is impossible to irrigate deep wounds and, moreover, Most of these bandages have a very complex structure. Those disclosed in the above-mentioned patents The methods suffer from practical inconveniences, making them unsuitable for clinical use.

Thus, there is a great need for aids to improve and simplify the treatment of deep wounds. There is. This auxiliary device is inexpensive, easy to handle, and relieves pain. There must be.

One objective of the present invention is to treat all types of wound cavities regardless of the depth of the wound cavity. It is an object of the present invention to provide an irrigating dressing that can be used for various purposes and can be manufactured at low cost.

Another object of the invention is that it can be handled by untrained personnel and that patients The purpose of the present invention is to provide an irrigated dressing that does not impede a person's free movement.

Yet another object of the invention is to reduce the number of wound cavity re-dressings compared to current technology. It is to provide a greatly reducing irrigation bandage.

These purposes include an outer layer, an inner adhesive layer, and optionally an adhesive layer affixed to said adhesive layer. a substantially air- and water-impermeable flexible plate made of a release layer; At least one hole is formed in the plate of the The irrigation bag is connected with a conduit for pulling in and out, and the hole is also used for pressure equalization. Achieved by obi.

The invention will be described in detail below with reference to the accompanying drawings, which schematically illustrate embodiments of the invention. I will clarify.

FIG.

Example 1 and 2 illustrate an irrigated dressing according to the invention, which irrigated dressing has an outer □ side layer. 2 and an inner adhesive layer 3, comprising a flexible plate 1 that easily conforms to the skin. . The outer layer is an air and liquid impermeable flexible material, e.g. polyurethane foam. The inner adhesive layer is made of, for example, a hydrocolloid adhesive. inside A protective paper 5 is provided on the adhesive layer 3, and this protective paper is used as a package in a modified form. may form part of the In the center between the outer layer and the inner layer, there is a layer of silicone, for example. There is a supplementary rule part 4 that has been completed.

In a variant, this supplement may be provided on the top or bottom side of the plate 1.

Two holes 6.7 are formed in the plate l and the supplementary part 4, and a connection 8.9 connects them. located in the hole. Because it supplies and drains liquid, it is gentle on the skin and A conduit 10 made of an unbreakable flexible material is secured to the connection 8 of the hole 6. . This conduit is, for example, a thick-walled silicone hose. The bottom end of this hose is It is better to have a straight cut, but it is better to have a pointed end. facilitates use of the hose. Furthermore, a flexible pad 11, e.g. an open capillary system A cylindrical piece of synthetic fiber or foam rubber forming a foam is placed at the lower end of the hose. has been done. This pad at the end of the conduit frees up more space in the wound cavity. can be satisfied at least. The conduit 10 may have a predetermined length or a suitable length. The weakened part, that is, the break line 17, so that it can be pulled apart according to the desired length. Either have it at various heights. This is shown in FIG.

The outer layer 2 of the plate 1 as well as the conduits 10 and rigid parts 4 are made of silicone, vinyl chloride. May be made of plastic or any other suitable plastic or rubber .

The bore 7, together with the associated connection 9, has a pressure equalization function.

Air passes freely here. Although hole 7 is not necessarily provided with a connecting portion, , preferably consists of a through hole. When the connecting part is placed in the hole 7, the modified form is water. A seal 13 (see Figure 3) is preferably provided to ensure sufficient clearance within the narrow hole area. If there is no time limit, a water sealing device that is only temporarily connected to the connection and then removed. It is preferable to provide a location (not shown). In yet another embodiment, as shown in FIG. A water level indicator 14, for example a transparent rubber hose, is attached to the connection. . The wound cavity is thus filled with irrigation fluid and suction removal must begin. Visual confirmation can be performed when the vehicle is not available. As is clear from Figure 5, bacteria do not enter the It is preferable to provide an air filter 15 in the hole 7 to prevent the air from entering the air. It is shown in Figure 6. In addition, an area made of a porous air permeable material can be used instead of an open book permeable layer and an adhesive layer. The area 16 can also be provided in the plate 1 instead of the hole 7, thus performing the pressure equalization function. vinegar. In this case, the porous material suitably has a water-repellent surface on the side facing the skin. . Both connections 8 and 9 are suitably adapted to be connected to a hospital exit system. ing.

In order to eliminate parts that protrude and get in the way, the connecting parts 8 and 9 should be The outer surface of the outer layer 2, that is, the side opposite to the side that is applied with the adhesive layer, is seated in a dish shape. It's hollowed out. Supplementary plate part 4 allows the bandage to be applied sufficiently without this plate. It may not be provided if it is stable. Before use and after irrigation and drainage, the above two The joint can be closed with a piece of adhesive tape or with a lid, e.g. a silicone bandage. Ru.

On the side facing away from the side of the hose there is a hole 6 and a connection associated with this hole. For example, a syringe ( (see Figure 1). In case of large wound cavity, It is necessary to fill the cavity with a drip. In these cases, eject the cavity. A connection with an associated syringe for dispensing may be connected to the two-way valve. child The syringe draws liquid out of the cavity in one direction and in the other direction. being pushed out.

In a variant, a single hole is formed in plate 1 for the supply and discharge of liquid and for pressure equalization. can do. This is achieved by a double conduit 10 connected to the hole. or by passing air from the wound cavity to the side of the conduit.

FIG. 8 illustrates yet another embodiment of the irrigated dressing of the present invention. This irrigation bandage is It has a permeable bag 18, which is used to fill the wound cavity. Water This bag, wholly or partially filled with a liquid such as, or a gas such as air, is When pressed, it conforms to the shape of the wall of the wound cavity. When using this bag, the pressure No shrinkage or other filler material is required. Usually this bag is elastic and high Made of molecular materials, sometimes foam materials or latex rubber, It may be inelastic. This bag provides support and contributes to immobilization. Not only that, but the foreign body also stimulates the healing process.

In this case, the plate 1 has an additional device for connecting the bag 18 and for refilling this bag. Another opening 19 is formed. For example, a rubber membrane is provided in this frontage 19. Ru. This embodiment further facilitates wound dressing for both patients and personnel. make it easier Advantageously, the irrigation according to the invention includes a layer between the bag and the wound surface.

Bag 18° also has a positive function. This bag can be used, for example, inside a bag filled with liquid. It is made of a semi-permeable membrane so that, for example, a drug preparation can pass therethrough. deformation In this embodiment, pharmaceutical preparations, other healing substances, disinfectants, etc. may be provided on the walls of the bag.

After the liquid level reaches plate 1, it is possible to facilitate suction of the liquid from the wound cavity. An open communicating tube or duct 24 (see Figure 1a) is placed in the wall of the bag facing the surface of the wound in order to ), the duct directing the liquid towards the pad 11 or the opening of the conduit 10. Useful for distributing and discharging. This bag is as shown in Figure 10b. In addition, instead of a separate duct, the clamping may have a section 25, these clamping The portion 25 consequently forms a duct between the wall of the bag and the surface of the wound. these The fastening part is made of a less elastic material of the bag with reference number 25. . In addition, a capillary active material, such as a fabric, can be applied to the outer wall of the bag to allow drainage of irrigation fluid. It's better to make it easier. Another embodiment includes one liquid duct in the layer between the outer and inner walls. The objective is to design the bag 1) 8 with a double wall so that a In this case The outer wall may also be made of semi-permeable material, or capillary active material, through which drug preparations can pass, for example. It is best if it is made of one of the following materials. Additionally, the duct may be fully or partially perforated. It is best to have a duct perforated in the bag, either completely or partially. It is preferably made of both a capillary material and a semi-permeable material at the same time.

The bag 18 also serves essentially as a stabilizer after irrigation. In this case, the bag is a book For use not only with the irrigated bandage of the invention, but also with other separate plates or adhesive layers. Can be done. By being a foreign body in the wound, the sac stimulates the healing process. introduction of bags To further facilitate the process, the connection between plate 1 and bag 18 is extended with a hose. , 4 is better.

FIG. 9 illustrates one embodiment of the lower portion of conduit 10. FIG.

This embodiment is particularly suitable for use in the case of bandages with bags. this place The end of the burnt conduit, which is placed in the deepest part of the wound, may have a capillary or non-capillary function. A group with the ability.

A pad 11 with communicating or non-communicating chambers or ducts 22 is provided. case In some cases, the pad is a stabilizer that holds the duct open against external or internal pressure. It has a means of conversion. The chambers or ducts of the pad open outwardly and into the conduit 10 and are It communicates with a flexible tube 21 that may have holes formed in its main or non-main parts. It is better. These flexible tubes are distributed over the wound surface and allow fluid flow from the wound. Irrigation fluid drains into the pad through these tubes between the bag and the wound surface.

In a variant, the pad can be made of a more rigid material, such as a skin-friendly plastic. coming. This pad has multiple holes to distribute irrigation fluid over a large area. has.

In the embodiment described above using a bag 18, the conduit 10 is placed on the side of the bag.

It will be appreciated that the conduit 10 may extend through the bag 18.

The irrigation bandage according to the invention works as follows. conduit 10, and optionally Place the pad 11 at the end of the conduit in the deepest part of the wound cavity to be treated; At this time, fill the remainder of the cavity with gauze compress. This embodiment uses bag 18. When used in place of Place it in the wound cavity for minor adjustments. Then, place the plate with the adhesive facing the skin. 1 onto the wound cavity, and when the plate is in place, connect the connecting parts 8 and Seal this system except for 9. Irrigation treatment completely fills the cavity. The surface of the wound is always facing upwards as shown.

The conduit and pad are then placed in the deepest part of the wound. The wound cavity is also very large. If not, connect the syringe to the connection part 8 and check that the cavity is filled. ’ indicates: Supply irrigation fluid to the cavity until indicated. Next.

Drain the cavity, remove the syringe and close the connection. Pad 11 is for scratches. It also helps absorb liquid at the bottom of the bottle. This cannot be done only at the hose end. I can't do that. After suction, the compress inside the wound cavity is filled with liquid to about 50%. Make peace.

The invention is illustrated by the following examples. However, Kajinaka et al., these examples illustrate the present invention. It's not a limitation.

Example 1 Irrigation of small cavities smaller than 501 (e.g. adenomas draining pus) Fit a 50 ct x 3 syringe of fill flow into the connection with the conduit. water seal closed When the indicator indicates that the fill or cavity is full, Inject the liquid until there is resistance. Next, the injected liquid made me feel 7 years old. A syringe is also used to aspirate the pus α and any bacteria present in the wound before irrigation.

Next, remove the syringe and water seal or indicator.

The joint is sealed, creating a wound-occlusion condition until the next irrigation.

Filling the cavity with the gauze compress will cause the capillary active gauze material to fill and become woven. The liquid flowing through the object is guided towards the pad by the suction force□.・Gauze? , wash away the pus, which eliminates the need for bandages.・6, Example 2 Irrigation of large cavities above 501 (e.g. bedsores) Attach the IV bag with associated equipment to the connection via the conduit. The wound in Example 1 Fill as shown. The device is then removed and a syringe equipped with a two-way valve is connected. drainage Direct the liquid into a urine bag or plastic bag. Fluid drains from cavity Suction is performed several times until the

With the irrigated bandage of the present invention, one bandage can be used instead of three to seven bandages each day. This will alleviate both physical and mental harm to the patient and improve medical services. Save time and a lot of money. Furthermore, the irrigated dressing of the present invention is very easy to handle. and therefore does not require specially trained personnel. The patient handles the bandage himself/herself. It is also possible. The bandage has no protrusions when not used for irrigation; Very suitable for patients with bedsores, allowing patients to move freely. this Bandages can be used on both large and small wounds. Especially vulnerable to conduits. If there is a broken area or break line and the bag is attached to it, the bandage should not be removed. Can be easily adapted to specific cavities.
