JP5246397B2 - Wound bag and drainage management tool or negative pressure closure therapy tool using the wound bag - Google Patents

Description

  The present invention relates to a wound bag and a drainage management tool or negative pressure closure therapy tool using the wound bag.

  Conventionally, in the treatment of wounds, burns, pressure ulcers, ulcers and the like (hereinafter sometimes referred to simply as “affected areas”), protection from the physical irritation to the affected areas, absorption of excessive exudate and maintenance of a moist environment, For the purpose of preventing contamination from the outside, a method of disposing a sterilized absorbent pad or the like on an affected area and fixing it to the surrounding skin with a bandage or an adhesive tape has been generally performed.

  Currently, negative pressure closure therapy is used in combination as a method for further promoting healing. Here, negative pressure closure therapy is a treatment method that promotes healing by placing an affected area under negative pressure.

A well-known method of performing negative pressure closure therapy is to place an absorption pad on the affected area, place a suction tube on the absorbent pad, and cover a wide area including the affected area with a bag-like cover. (See Patent Document 1).
Such a treatment method is an effective method for the extremities of limbs such as limbs in which a film cannot be hermetically applied to the body due to unevenness of the body.

Recently, it has been proposed to perform rehabilitation in a state in which a negative pressure is released by attaching a bag-like cover so that the joints and the like are not stiffened while performing negative pressure closure therapy (see Patent Document 2).
This is because in a wound bag using a bag-like cover, the body other than the affected part is also covered, so that the movement of the body other than the affected part is restricted, and as a result, the joint and the like are hardened.

JP-T 09-503923 JP 2007-97860 A

  By the way, when there is an affected part in the hand, rehabilitation is often performed with the forearm raised in the vertical direction. Further, when the zipper provided on the cover is opened in order to treat the affected part and the affected part is taken out from the bag-like cover, the forearm may be raised vertically.

  However, in the conventional bag-shaped cover, the pressure-sensitive adhesive layer provided on the skin side of the opening for inserting the limbs, or the cover is covered with the adhesive tape over and over the opening. The method of making it adhere to the body has been taken. Therefore, when the forearm is lifted in the vertical direction in such a state, exudate or the like accumulates in the opening.

When the bag-like cover is fixed by the adhesive layer, there is a problem that the exudate accumulated in the opening enters the adhesive layer when the arm is vertical, and the adhesive force is reduced.
Also, when fixing the bag-shaped cover by covering it with the adhesive tape from the top of the opening to the body, fold the opening of the bag-shaped cover to the thickness of the arm or foot and then use the adhesive tape. Since it must be fixed, there is also a problem that exudate leaks from the overlap of the folded covers.
Therefore, care must always be taken so that the exudate does not leak out, and there is a possibility that sufficient rehabilitation cannot be performed.

  Furthermore, when exudate touches a part other than the affected part during rehabilitation, there is a problem that the patient feels uncomfortable.

  The present invention has been made in view of the above-described problems, and is a wound bag capable of preventing a decrease in adhesive force and leakage of exudate and reducing discomfort caused by contact of exudate with a body other than the affected part, and An object of the present invention is to provide a drainage management tool or a negative pressure closure therapy tool using the wound bag.

To solve the above problems, the present invention is secured a bag-shaped cover for covering the affected area, and an opening for inserting the diseased part to the bag-like in the cover, the bag-shaped cover body In order to connect the sealing means provided in the opening to the suction means for sucking the inside of the bag-like cover, the wound means includes the bag-like cover . The opening is joined to the cover, and the opening is formed on the inner side by a predetermined distance from the end of the bag-like cover, straddling the sealing means and the cover. The “bag shape” of the bag-shaped cover for covering the affected part means not only a bag shape but also a sleeve shape.

In addition, the present invention is provided in the bag-like cover for covering the affected part, an opening part for inserting the affected part into the bag-like cover, and the opening part for fixing the cover to the body. A wound bag comprising: a sealing means; and a communicating part for connecting to a suction means for sucking the inside of the bag-like cover, wherein the bag-like cover comprises upper and lower surfaces, and the opening is The cover is formed at a predetermined distance from the end of the upper and / or lower surface of the cover, and is joined to the upper and / or lower surface of the bag-like cover excluding the peripheral portion adjacent to the opening. You can also.

Furthermore, the following invention is preferable as an embodiment of the said invention. That is, the bag-like cover is preferably provided with a hollow end in which the hollow portion is formed between the closed end portion of the side is inserting the diseased part and said end portion and the opening.
Further, the sealing means is a patch material divided into a first region, a second region, and a third region, and the first region has the opening in the center, and the second region and the second region. It is adjacent to the three regions, and the first region and the second region are bonded together, and the cover is fixed to the body by bonding the second region and the third region. preferable.

  Furthermore, it is preferable that the said hollow end part is comprised as a liquid reservoir part with respect to the exudate from an affected part. It is preferable to provide two or more openings. Furthermore, it is preferable to provide an airtight fastener on the bag-like cover. Moreover, it is preferable to provide a placement mark for the affected part on at least one member of the wound bag.

  Furthermore, the invention relating to the drainage management tool and the negative pressure closure therapy tool is characterized in that any one of the wound bag inventions is used.

According to the present invention, the end of the affected part insertion side is closed to form the hollow end liquid reservoir, so that the exudate can be stored in the liquid reservoir. Thereby, since the quantity of the exudate which touches an adhesive layer can be reduced, the adhesive force becomes weak and a possibility that the exudate may leak can be prevented.
Further, by providing the opening on the upper surface and / or the lower surface of the bag-like cover, the liquid reservoir can be easily provided without providing a separate member.
Furthermore, by providing the opening on the upper surface and / or the lower surface of the bag-like cover, the opening provided on the peripheral edge of the conventional bag is eliminated, so that a communication port can be provided on any peripheral edge.

The support 340 does not necessarily need to cover the entire upper surface of the base material 310 if the base material 310 can be maintained in a fixed state when the base material 310 is pasted. For example, only the peripheral edge of the base material 310 is covered in a window frame shape. And the center part of the base material 310 can also be made into the form which is not coat | covered.
In addition, as a method of temporarily attaching the support body 340 to the base material 310, well-known methods, such as adhesion | attachment, thermocompression bonding, and temporary attachment by co-extrusion, can be used.

  Note that the patch 300 used for the sealing means 30 is one that can ensure moisture permeability, air tightness, and safety among the followability to the body, moisture permeability, air tightness, and safety of the adhesive to the skin. There is no particular limitation.

The release sheet 330 is not particularly limited as long as it includes at least the release sheet 330.

<Communication unit 40>
The communication part 40 is for connecting the inside of the cover 10 to the suction means, and is provided on the front side of the right long edge of the cover 10 as shown in FIG.
Moreover, the communication part 40 concerning this embodiment is comprised by the communication port 41 which notched a part of the right long side edge part of the welded cover 10, and the adhesive material 300a larger than the opening diameter of the communication port 41. Has been.

When forming the cover 10, the communication portion 40 may be formed by not thermally welding a part of the right long edge of the film.
In the present embodiment, the shape, size, and position of the communication port 41 are not particularly limited as long as a tube for connecting to the suction unit can be inserted, and can be changed as appropriate. Furthermore, since the adhesive material 300a in this embodiment has the same structure as the adhesive material 300 described above, the description thereof is omitted.

  It is preferable that the wound bag 1 according to the present embodiment further includes a fastener 50 as described below.

<Fastener 50>
The airtight fastener 50 is for making it easier to treat the affected part by opening the fastener 50 even after the cover 10 is fixed to the body by the sealing means 30.

As shown in FIGS. 1A and 1B, the fastener 50 according to the present embodiment is provided substantially at the center of the cover 10 so that the affected part is directly below the fastener 50.
Note that the position of the fastener 50 is not limited to the present embodiment, and the fastener 50 may be provided at the front short side edge or the left and right long side edges of the film.
Further, the configuration of the fastener 50 is not particularly limited as long as it is airtight and resealable. For example, the fastener 50 can be engaged by sliding a protrusion and a groove, an adhesive tape, a surface Examples include fasteners.

<Fastener opening holding member 60>
The fastener opening holding member 60 is a member for maintaining the shape of the opening of the fastener 50 when the fastener 50 is opened. For example, the fastener opening holding member 60 is a member having a rectangular shape in plan view of 1 cm vertically and 16 cm left and right.
In this embodiment, as shown to Fig.1 (a), it is directly under the fastener 50, and is provided over the left-right width direction. Moreover, as shown in FIG.1 (b), one each is provided in the front side and the back side of the fastener 50. As shown in FIG.

  Here, it is preferable that the fastener opening holding member 60 is deformable and can hold a deformed state. For example, a material that can be plastically deformed by applying force with a finger and can maintain the open / close state of the fastener opening is preferable. As the fastener opening holding member 60, for example, a resin material, a paper material, or a metallic material can be used.

  Resin materials include commercially available resin shape-retaining materials using polyethylene and polypropylene fine wires and plates, such as Sekisui Chemical Co., Ltd. super-stretched sheets and resin shape-retaining tapes, Mitsui Chemicals, Inc. It is possible to use a shape-retaining material made of a product, a trade name “Techno Roto (registered trademark)” or the like.

The former is a high-strength, high-elastic modulus sheet or tape obtained by stretching polyolefin (PE, PP) in a uniaxial direction at a high magnification. The latter techno funnel is, for example, a tape formed by combining polyethylene thin wire with a diameter of 0.67 mm as a core material and polyethylene as an exterior film, and can be bent freely like a wire, The feature is that there is almost no bending return at the time of bending.
Both the former and the latter can be suitably used for opening and closing the opening and holding the shape at that time because there are various types of cross-sectional shape, shape retention, strength, and the like depending on the application.
Further, as another resin material, a resin material containing an inorganic filler can be used. This material can be formed by extruding or stretching a molten resin obtained by mixing a polyolefin (PE, PP) resin with an inorganic filler (talc, calcium carbonate, titanium oxide, etc.). By mixing the inorganic filler with the resin in this way, it is possible to impart plastic deformability that can maintain the open / closed state of the opening, that is, the shape maintaining function, while giving the resin a certain level of elasticity.

  As the paper material, a waterproof paper material having a shape maintaining function can be used. As the waterproofing treatment, a method of coating paper with a hydrophobic resin or a method of coating or laminating a resin film or sheet on paper can be employed. By performing such processing, the paper-made fastener opening assisting member 60 can absorb exudate water and water during washing, and prevent the strength from being reduced or destroyed. Further, it is possible to give the paper a moderate waist that is easy to handle as the fastener opening auxiliary member 60.

  As the metal material, for example, a twist binding material, that is, a wire material in which a thin metal wire is covered with a vinyl resin (for example, trade name “Vintai (registered trademark)” manufactured by Kyowa Co., Ltd., trade name “Union Plastic Co., Ltd.” Quick tie "etc.) can be used.

The opening holding member 60 is preferably made of resin or paper, and more preferably made of resin.
In addition, the fastener opening holding member 60 in the present embodiment is configured to be detachably provided around the fastener 50 via an adhesive, but is not limited thereto, and is not limited thereto, such as adhesion, adhesion, and welding. The fixing means may be installed, or the fastener opening holding member 60 may be covered and fixed with an adhesive tape.

≪How to use wound bag 1≫
A method of using the wound bag 1 will be described by taking as an example a case where the affected part is in the hand.
FIG. 2 is a step-by-step diagram showing a method for fixing the cover 10 to the body B by the sealing means 30.

  First, as shown to Fig.2 (a), the peeling sheet 330 of the back side of the patch 300 concerning this embodiment is peeled off. At this time, since a slit S (see FIG. 1 (c)) is provided in the release sheet over the left and right width direction at the center of the patch 300 (corresponding to the boundary between L1 and L2 in FIG. 1 (b)), Only the rear half release sheet can be peeled off first.

After peeling off the rear release sheet 330, the body B is inserted into the cover 10 through the opening 20 communicating with the cover 10. At this time, since the circular punching is provided at both ends of the notch that is the opening, it is possible to prevent the cover 10 from tearing when the affected part is inserted. At this time, the punching shape may be a polygonal shape, but is preferably a circular shape.
Further, the cover 10 may be prevented from being torn by reinforcing the both end portions of the slit with another adhesive material (for example, tape or the like) without providing punching.

  Furthermore, before peeling off the release sheet 330, the width of the opening 20 may be changed in accordance with the width of the body B to be inserted by further widening the cut using a scissors or the like. Moreover, you may process the opening part 20 in shapes, such as circular in planar view. By doing in this way, an affected part can be made easy to insert in a cover.

In the present embodiment, the cover 10 can be temporarily attached to the body B via the pressure-sensitive adhesive layer 320 by peeling a part of the release sheet 330 of the patch 300, so that the cover 10 is appropriate in the subsequent operation. Can be prevented from shifting from a proper position.
Note that after inserting the body B, the rear release sheet 330 may be peeled off. At this time, if the release sheet 330 is provided with a slit, it can be easily peeled off.

Next, as shown in FIGS. 2B and 2C, the release sheet 330 on the front side of the patch 300 is peeled off. Then, the adhesive layers 320 are bonded together by being folded and folded at the center of the adhesive material 300 (corresponding to the boundary between L1 and L2 in FIG. 1B). In other words, the first area and the second area of the sealing means 30 are bonded together, and the second area and the third area are bonded together. Thereby, the seal | sticker means 30 can be stuck to the body B, and the circumference | surroundings can be kept airtight.
At this time, by providing a placement mark (not shown) of the affected part or body B in the cover 10 or the sealing means 30, the affected part can be guided to an appropriate position. The placement mark is, for example, a marking that displays an appropriate position range of the front, back, left, and right of the hand, and various forms such as a simple linear mark and a figure shape mark can be adopted as necessary.

In the present embodiment, the front long side of the double-sided tape T to which the cover 10 and the adhesive material 300 are joined coincides with the center line in the front-rear direction of the adhesive material 300, so that it is easy to bend.
Further, as shown in FIG. 1B, since the adhesive material 300 is not fixed to the cover 10 at the front and rear length L3, when the adhesive materials 300 are overlapped, the two adhesive materials 300 are moved up and down. Easy to handle from the direction. Thereby, since the patch 300 can be more closely attached to the body B, the opening 20 can be kept airtight.
Here, “sealing” means that there is sufficient airtightness that the inside of the cover 10 can be maintained at a lower pressure than the surroundings when sucked by a suction pump.
Then, the followability to the body B can be made favorable by peeling the support body 340 of the sealing means 30. FIG.

Here, conventionally, when the cover film is folded to fit the thickness of the limbs and then sealed with an adhesive tape, congestion and pain have occurred depending on the thickness and location of the film. Moreover, when it stopped with a rubber band, the blood flow stopped, preventing early healing.
However, as in the present embodiment, by fixing the cover 10 to the body B by the sealing means 30, the occurrence of congestion and pain is prevented, and early healing is not hindered.

  Next, the fastener 50 is opened, and the absorbent pad 70 for covering the wound is disposed on the affected part (see FIG. 3).

In this embodiment, when opening the fastener 50, the fastener opening holding member 60 is also spread with a finger. At this time, since the fastener opening holding member 60 is harder than the film material of the cover 10 (because there is stiffness), the opening shape of the fastener 50 can be easily held.
Thereby, since the opening shape of the fastener 50 can be hold | maintained, it can carry out treatment of a wound with both hands, or can make it easy to observe an affected part.
The shape of the fastener opening holding member 60 is not limited to the rectangular shape as in the present embodiment, and can be appropriately changed, for example, a linear shape or a wavy shape. Moreover, you may enable it to hold | maintain the opening shape of the fastener 50 by providing multiple members with the short length of the left-right width direction concerning this embodiment.

After retaining the opening shape of the fastener 50, an absorbent pad is placed over the wound.
Here, the absorbent pad 70 is a known porous pad and serves as an appropriate cushion to reduce physical stimulation from the cover 10 generated during decompression by being disposed on the affected part. In addition, the exudate can be efficiently absorbed and the pressure can be reduced uniformly by being porous. Furthermore, under the negative pressure, the films of the cover 10 may stick to each other, and the suction operation cannot be performed efficiently by the catheter C. However, since the space can be secured by providing the absorption pad 70, the suction operation can be performed efficiently. It can be performed.

  As the absorbent pad 70, fiber materials such as knitted fabrics, woven fabrics, and nonwoven fabrics, foam materials, and the like can be used. Moreover, as a fiber material and a foam material, the same material as the base material of the patch 300 (see FIG. 1A) can be used.

The catheter C is preferably disposed on the absorbent pad 70 or in the vicinity of the affected area, but the position of the catheter C is not particularly limited as long as the exudate is sucked and the affected area is at a suitable negative pressure. .
Further, as the catheter C, a catheter provided with a plurality of openings on the side surface of the catheter may be used.

After disposing the absorption pad 70 on the affected part, the other end of the catheter C, one end of which is connected to the suction means, is drawn from the communication port 41 of the communication unit 40 and placed on the absorption pad 70. Then, the fastener 50 is closed. At this time, the fastener 50 can be sealed and closed by pressing the fastener 50 and the fastener opening holding member 60 with a finger.
In the present embodiment, the fastener opening holding member 60 is installed immediately below the fastener 50. However, as long as the opening shape of the fastener 50 can be maintained, the present invention is not limited to this and can be appropriately changed.

Next, the catheter C pulled out from the communication port 41 of the communication unit 40 is similarly sealed by bonding the patch 300a.
In the present embodiment, since the length of the catheter C can be sufficiently adjusted and then adhered by the patch 300a, there is no possibility that the length of the catheter C will be insufficient. Moreover, since it can contact | adhere so that the circumference | surroundings of the catheter C may be wrapped, airtightness can also be ensured.
At this time, another adhesive material larger than the adhesive material 300a may be provided, and further airtightness may be secured by further attaching the adhesive material 300a.

Then, suction is performed by suction means connected to one end of the catheter. The negative pressure at this time is preferably reduced from atmospheric pressure to about 125 mmHg, but is not limited to this, and can be changed as appropriate by the judgment of the medical staff.
In addition, about the treatment method of negative pressure closure therapy, it can change suitably.

  On the other hand, when performing rehabilitation, the suction is released, and the rehabilitation is performed in the cover 10 by returning to atmospheric pressure or pressurizing.

Here, when the forearm is raised in the vertical direction during rehabilitation, exudate drips to the opening 20 side, but in this embodiment, the liquid reservoir 25 (FIG. 1 (a) provided on the back side (elbow side). ))) Exudate is accumulated. Thereby, since the quantity of the exudate which continues to contact an adhesive layer can be reduced compared with the past, the fall of adhesive force can be prevented.
Further, since the exudate is accumulated in the liquid reservoir 25, the exudate does not always accumulate around the arm as in the prior art. This eliminates patient discomfort.
Furthermore, the exudate collected in the liquid reservoir 25 can be provided with a discharge port at the rear peripheral edge of the cover 10 that could not be installed conventionally. Thereby, exudate etc. can be discharged | emitted suitably, performing rehabilitation.

Further, when the negative pressure is temporarily released to replace the absorbent pad 70 or to treat the affected part, it can be easily performed by opening the fastener 50. This is economical because the wound bag 1 once attached does not need to be replaced every time the absorbent pad 70 is replaced or the affected area is treated.
Furthermore, since the fastener opening holding member 60 according to the present embodiment is configured to be detachable and is not contaminated by the exudate of the patient, the fastener opening holding member 60 can be used repeatedly even when the wound bag 1 is replaced. Is. In addition, when the fastener opening holding member 60 is made of metal, it is possible to facilitate the separation when the wound bag 1 is treated as garbage.

In the present invention, the shape of the sealing means 30a may be as shown in FIG.
Here, FIG. 4 is a schematic explanatory view showing the wound bag 1 according to the second embodiment, wherein (a) is a perspective view showing a state before use, and (b) is a state in use. It is a perspective view shown.
In the second embodiment, description will be made with the vertical and horizontal directions defined based on the state of FIG.

  As shown in FIG. 4A, the sealing means 30a of the wound bag 1 according to the second embodiment is different from the sealing means 30 according to the above-described embodiment (see FIG. 1A). The length in the width direction is longer than the length of the cover 10 in the left-right width direction.

Here, the sealing means 30a constitutes three regions as shown in FIG.
In the sealing means 30 according to the second embodiment, the first region is a region where the length in the front-rear direction is L2 and the length in the left-right width direction is L4. The second region is a region adjacent to the rear side of the first region, the length in the front-rear direction is L3, and the length in the left-right width direction is L4. The third region is a region adjacent to the right side of the first region and the second region, and has a length in the front-rear direction of L1 and a length in the left-right width direction of L5.

The sealing means 30a is joined to the cover 10 via a double-sided tape (not shown), as in the above embodiment.
More specifically, in the sealing unit 30a, the cover 10 (upper surface in the drawing) and the first region are joined via the double-sided tape T. On the other hand, the second area and the third area can be moved because they are not joined to the cover 10.

  Furthermore, the opening 20 is formed across the sealing means 30a and the upper surface of the cover 10 to which the sealing means 30a is joined, as in the above embodiment.

Here, the relationship between the length of L1 and the length of L2 + L3 is preferably such that the length of L1 ≧ the length of L2 + L3, and more preferably, the length of L1 is about 10 mm longer than the length of L2 + L3. Moreover, it is preferable that the relationship between the lengths in the left-right width direction is L4 = L5.
In the second embodiment, as shown in FIG. 4B, the length of L2 + L3 in the front-rear direction is equal to the length of L1. The length L4 in the left-right width direction is equal to the length L5.

The usage method of 2nd Embodiment is demonstrated.
In addition, about the usage method, since it is the same as that of the said embodiment until the place which inserts an affected part in the cover 10, detailed description is abbreviate | omitted.

  After inserting the affected part into the cover 10, the medical worker peels off the release sheet in the third region on the sealing means 30 a, and the adhesive layer in the third region and the adhesive layer in the first and second regions are bonded together. Paste from right to left. In other words, as shown in FIG. 4B, the first region and the third region of the sealing means 30a are bonded together, and the second region and the third region are bonded together. Thereby, the seal | sticker means 30a can be stuck to the body B, and the circumference | surroundings can be hold | maintained airtight.

  At this time, since a slit (not shown) is provided in the release sheet in the center in the left-right width direction of the sealing means 30a, the release sheet in the first and second regions and the release sheet in the third region Can be peeled off separately. Thereby, since it can stick together with the adhesive layer of 1st and 2nd area | region, peeling the peeling sheet of 3rd area | region gradually, the sealing means 30a can be stuck more closely on the body B, and can be stuck. At the same time, airtightness can be improved. Moreover, since it is not necessary to peel off the adhesive material of the sealing means 30a at a stretch, the adhesive layer can be prevented from sticking to an unexpected part.

Further, in the second embodiment, the short side on the right side of the double-sided tape joined with the cover 10 and the sealing means 30a coincides with the center line in the left-right width direction of the sealing means 30a, so that it is easy to bend. .
Furthermore, since the second region is not joined to the cover 10 in the second embodiment, the second region can be moved even after the third region is bonded.

  Thereafter, similarly to the above-described embodiment, negative pressure closure therapy can be performed by applying a negative pressure to the affected area.

  Note that when the area of the third region is larger than the areas of the first region and the second region, the protruding region is also bonded to the cover 10, so that the airtightness can be further improved.

(Third embodiment)
In the present invention, the catheter 41 may be held by, for example, one adhesive material, instead of sandwiching the communication port 41 between the two adhesive materials 300a as shown in FIG.

  As shown in FIG. 5 (a), the patch 300b of the wound bag 1 according to the third embodiment is similar to the sealing means 30 (see FIG. 1 (a)) in the length in the left-right width direction L2a. Now, it is joined to the cover 10 by a double-sided tape (not shown) in the front-rear direction. Therefore, the patch 300b is not joined to the cover 10 in the lengths L1a and L3a in the left-right width direction, and can be moved.

Here, as shown in FIG. 5, the patch 300b constitutes three regions.
In the patch 300b according to the third embodiment, the first region is a region in which the length in the left-right width direction is L2a and the length in the front-rear direction is t1. Further, the first region is provided in the central portion of the adhesive material 300b. The second region is a region provided on the right side of the first region, and is a region in which the length in the left-right width direction is L1a and the length in the front-rear direction is t2. The third region is a region provided on the left side of the first region, and is a region in which the length in the left-right width direction is L3a and the length in the front-rear direction is t1.
In addition, since the basic structure of the adhesive material 300b concerning 3rd Embodiment is the same as the above-mentioned sealing means 30, detailed description is abbreviate | omitted.

Further, as shown in FIG. 5 (a), the adhesive material according to the third embodiment has a width t1 in the front-rear direction of the adhesive material 300b on the cover side (L2a + L3a side) and the side protruding from the edge of the cover 10 ( The length of the width t2 in the front-rear direction of the adhesive material 300b on the L1a side is different.
Further, a communication port 41 having a circular shape in plan view for introducing the catheter C into the cover 10 is provided on the adhesive material 300b.

Here, the relationship between the length of L1a and the length of L2a + L3a is preferably the length of L1a ≧ the length of L2a + L3a, and more preferably the length of L1a is longer by about 10 mm than the length of L2a + L3a.
Further, the relationship between the widths of t1 and t2 is preferably t2 ≧ t1, and more preferably longer by 5 mm or more from the width of t1 in the front-rear and left directions (see FIG. 5B). ).

In the third embodiment, a circular communication port 41 for introducing the catheter C into the cover 10 is provided on the adhesive material 300b.
More specifically, the communication port 41 is provided at the center of a region (region of the left-right width direction L2a × width t1) joined to the cover 10 by the double-sided tape. And it is provided so that the cover 10, the double-sided tape (not shown) which joins the cover 10 and the adhesive material 300b, and the adhesive material 300b may be connected.

  In the third embodiment, the communication port 41 is formed in a circular shape in plan view, but is not limited to this, and may have a polygonal shape. In addition, in order to make the cover 10 hard to tear, it is more preferable that it is circular.

  The usage method of 3rd Embodiment is demonstrated. Since the usage method is substantially the same as the usage method of the sealing means 30 described above, detailed description thereof is omitted.

  In 3rd Embodiment, the catheter C inserted from the communication port 41 is mounted on the absorption pad 70 (refer FIG. 3) provided on the affected part. At this time, since the catheter C is temporarily attached by the adhesive layer of the adhesive material 300b as in the sealing means 30 (see FIG. 1A), the displacement of the catheter C can be prevented. In addition, it is more preferable to provide a slit (not shown) on the release sheet of the adhesive material 300b around the communication port 41 so that the release sheet can be easily peeled off.

  As shown in FIG.5 (b), in 3rd Embodiment, in the state which pulled out the catheter C which has come out from the communicating port 41 to the center side (opposite side edge side; left side) of the cover 10, it is a patch. The catheter C is fixed by bonding the 300b together. In other words, the first area and the second area of the sealing means 30 are bonded together, and the second area and the third area are bonded together. Thereby, even when a force is applied to the catheter C unexpectedly, since there is no gap between the catheter C and the patch 300b, it is possible to prevent the airtightness from being released.

  As shown in FIGS. 5A and 5B, in the third embodiment, the length in the vertical direction t2 is longer than the length in t1, and the length in the left-right width direction L1a is longer than L2a + L3a. Furthermore, the catheter C can be sufficiently covered. With such a configuration, not only can the catheter C be hermetically covered, but also the protruding adhesive layer that is not pasted with the adhesive on the cover 10 side is stuck to the cover 10, and the catheter C is attached. The cover 10 can be strongly held. Thereby, even when a sudden force is applied to the catheter C, since the catheter C is held by the cover 10, it is possible to prevent a gap from being formed between the catheter C and the adhesive material 300b.

Note that t2 = t1 and L1a = L2a + L3a may be used as long as the patch 300b has a size that can sufficiently ensure airtightness.
Further, the adhesive sheet 300b on the side protruding from the edge of the cover 10 (L1a side) and the adhesive layer having the same size as the adhesive material 300b on the cover 10 side (L2a + L3a side) can be exposed on the release sheet. A slit may be provided (not shown). With this configuration, the adhesive material 300b can be moved even after the catheter C is joined. Therefore, when the catheter C is pulled suddenly, the adhesive material 300b moves to reduce the impact, and the catheter C It is possible to prevent C from coming off the cover 10.

In the third embodiment, as shown in FIGS. 5A and 5B, only one communication port 41 is provided. However, a plurality of communication ports 41 may be provided by providing a plurality of patch materials 300b. Good. Thereby, since the medical worker can insert the catheter C from a favorite position, the communication port 41 into which the catheter C is inserted can be selected according to the position of the affected part.
Alternatively, physiological saline or a medicine may be poured from the catheter C inserted into one communication port 41 and the injection solution may be discharged from the catheter C provided at another communication port 41.
When a plurality of communication ports 41 are provided, the communication ports 41 may be blocked by bonding the adhesive material 300b, or may be blocked by a separate material (not shown) that can be reapplied and peeled off. When it is closed with another member, it can be used again at the next use, which is economically preferable.

(Fourth embodiment)
Further, in the present invention, the outlet port 42 may be provided in the communication port 41.

As shown in FIG. 6, the wound bag 1 according to the fourth embodiment includes a discharge port device 42 instead of the patch.
Here, the discharge mouthpiece 42 is comprised from the stopper 42a and the mouthpiece main body 42b. The stopper 42a is detachable from the mouthpiece main body 42b.

Furthermore, in 4th Embodiment, the mouthpiece main body 42b and the drainage tube D provided in the cover 10 are provided so that attachment or detachment is possible.
With this configuration, the drainage tube D can be used detachably, so that the wound bag 1 according to the present invention can be used for negative pressure closure therapy device or drainage management depending on the exudate and the condition of the wound. Can be used properly as a tool.
In the present embodiment, the case where the drainage tube D is used has been described. However, the present invention is not limited to this, and other catheters may be used.

  Since exudate and the like can maintain the affected area in a moderately moist environment, it is useful for early healing. However, excessive exudate or the like becomes a hotbed for breeding various germs and the like, which hinders early healing. Therefore, when exudate or the like accumulates in the cover 10, it is preferable to discharge excess exudate or the like from the discharge port device 42 to maintain an appropriate wet environment.

  For example, by connecting the catheter C connected to the suction means to the mouthpiece body 42b via the connector J, excess exudate can be removed and negative pressure closure therapy can be performed.

  When exudate is collected in the cover 10 with the drainage tube D removed, the exudate collected in the cover 10 is removed by removing the plug 42a of the discharge port 42 from the discharge port main body 42b. Etc. can be discharged to the outside. Furthermore, one end of the tube is directly connected to the discharge port main body 42b, and a drainage bag is connected to the other end, so that the exudate in the cover 10 is guided to a drainage bag (not shown) by natural fall. You can also.

  In the present invention, it can be used not only as a negative pressure closure therapy device or a drainage management device but also as a wound cleaning bag.

For example, in pressure sores, exudate does not ooze from necrotic tissue, and the affected area cannot be maintained in a moist environment. Therefore, there is a problem that healing is not promoted.
Therefore, after the necrotic tissue is removed by surgery, healing can be promoted by placing the affected part in a wound dressing and maintaining a moist environment.

For example, two communication ports 41 (see FIG. 1 (a)) are provided as a method of making the wet environment, and a liquid such as physiological saline is supplied from one side and drained liquid or the like is discharged from the other side. With this, a humid environment can be created.
As a result, when the amount of drainage is large, drainage is sucked from the communication port 41, and when the affected part is dry, it is possible to create a moist environment by adding physiological saline or the like from the communication port 41. is there.
Furthermore, since necrotic tissue can be washed away by flowing physiological saline or the like, early healing can be achieved.
In addition to providing a plurality of communication ports 41 (see FIG. 1A) in the wound bag 1, a plurality of catheters C may be inserted into the communication ports 41 to cope with this.

Here, the liquid to be supplied is not limited to physiological saline. For example, autologous or allogeneic blood or blood products such as platelet lysate, plasma, or serum, platelet-derived growth factor (PDGF), intravascular growth Factor (VEGF), transforming growth factor α (TGFα), or transforming growth factor β (TGFβ-1, 2, or 3), basic fibroblast growth factor (b-FGF also known as FGF2), epithelium Purified natural or recombinantly produced protein growth factors such as cell growth factor (EGF), granulocyte macrophage colony stimulating factor (GM-CSF); insulin-like growth factor-1 (IGF-1) and keratinocyte growth Factor 2 (KGF2 (also known as FGF7));
Purified natural or recombinantly produced protein cytokines such as interleukin 1β (IL1β) or interleukin 8 (IL-8), other bioactive agents, and combinations thereof can be provided.

Also, proteolytic enzyme inhibition of purified natural proteins or recombinantly produced proteins such as metalloproteases (TIMP1-4) and α1-antitrypsin (AAT) tissue inhibitors, aprotinin, α-2-macroglobulin Agent;
Processes detrimental to wound healing from wound exudates, such as inhibitors of matrix metaproteases (MMP), inhibitors of neovascularization (angiogenesis) such as neutrophil elastase, thrombospondin or calistatin Inappropriate levels of antibodies or chemically synthesized molecules that inhibit or inactivate substances; and combinations thereof may be provided.

  According to such an embodiment, the affected area can be placed in an appropriate moist environment, so that early healing can be achieved.

In the fourth embodiment, it is possible to select whether to use the suction means according to the amount of exudate or the like.
Further, by providing a backflow prevention valve while connecting the drainage tube D and the discharge port 42, the inside of the cover 10 can be kept at a negative pressure even if the suction means is removed after suction by the suction means.
Furthermore, when the inside of the cover 10 is pressurized by changing the direction of the backflow prevention valve, the inside of the cover 10 can be maintained in a pressurized state. Thereby, it can make it easy to perform rehabilitation.

(Fifth embodiment)
Next, the structure of the wound bag 1 of 5th Embodiment is demonstrated with the perspective view of FIG.
The embodiment of FIG. 7 is the same as the embodiment of FIG. 1 in that the opening 20 is formed on the upper surface of the cover 10, but the sealing means 30 except for the peripheral portion adjacent to the opening 20. 1 is different from the embodiment of FIG. 1 in that it is joined to the upper surface of the cover 10. That is, the sealing means 30 of the embodiment of FIG. 7 has a configuration in which a window is opened in an adjacent peripheral portion of the opening 20.
According to the fifth embodiment, it is possible to prevent a decrease in adhesive force and leakage of exudate, and to reduce discomfort caused by contact of exudate with a body other than the affected part.

As mentioned above, although preferred embodiment of this invention was described, this invention is not limited to the said embodiment, In the range which does not deviate from the meaning of this invention, it can change suitably. For example, a sleeve-like wound bag can be obtained by providing two openings in the cover.
By adopting such a configuration, negative pressure closure therapy can be performed without restricting the body other than the affected part even in a wound in a joint part such as an elbow or a knee. Further, by providing the opening on the side surface of the cover, two reservoirs can be formed in the sleeve-like wound bag. As a result, the exudate is accumulated in one of the liquid reservoirs, so that it can be used regardless of the rehabilitation posture.

In addition, in 3rd Embodiment, it can also be used for the drainage management after the knee joint total replacement in a knee osteoarthritis, and the closed-type continuous washing method of an osteomyelitis patient.
Since the wound care device according to the third embodiment can block the affected part from the outside air and protect it airtightly, the risk of infection can be reduced. Moreover, it is easy for a medical worker to visually recognize the state of the affected part and the amount of exudate, and appropriate treatment can be performed.

  In the first embodiment, the sealing means is formed by using one adhesive material. However, the present invention is not limited to this, and for example, it may be formed by attaching two adhesive materials to the cover. Good.

Further, in the present invention, opening assisting means may be provided. For example, a configuration may be provided in which a string or the like is installed in the vicinity of the opening, and the opening is opened by pulling it up.
At this time, a preferable position of the string is a position that does not get in the way when the affected part is inserted, and is preferably installed around the opening. More preferably, it is an area of the sealing means joined to the cover, and is preferably provided closer to the affected part insertion direction side (or finger side in the case of the hand) than the opening.

In addition, the opening assisting means is not limited to a string, and is not particularly limited as long as it has a strength capable of opening the opening by pulling up.
With this configuration, when the opening is widened, the inside of the cover and the pressure-sensitive adhesive layer can be kept clean without being contaminated. Moreover, there is no possibility that the pressure-sensitive adhesive layer exposed by peeling off the release sheet may stick to an unexpected place.
The number and position of the opening assisting means can be changed as appropriate.
