特許文献1〜3には、患部周辺を気密性のカバー部材及びシール手段により気密状態にして、吸引管及び吸引手段により患部周辺を陰圧にする陰圧閉鎖療法用の陰圧閉鎖用具が記載されている。特許文献1〜3では、吸引管は、カバー部材に設けられた接続部（特許文献1の「コネクタ30」、特許文献2の「減圧接続部92」、特許文献3の「連通口41」）を介して陰圧密閉部から外部に導出されている。このような構成の陰圧閉鎖用具だと、カバー部材の端部の気密度を高めるほかに、カバー部材に設けられた吸引管の接続部の気密度を高める必要が生じる。カバー部材の設けられた接続部の気密度を高めようとすると、どうしても接続部の構造が複雑になってしまうため患者にとって邪魔になり、陰圧閉鎖用具を長期間着用する場合に生活活動に支障が生じる。さらに、吸引管のほか、洗浄液を供給する洗浄管や、薬液を供給する管などを設ける場合に、その都度、接続部を増設する必要があり、カバー部材の構造が複雑になるため、ますます長期着用に支障を生じてしまう。特に、手の創に用いた場合、用具装着下での手の運動は困難である。また、陰圧閉鎖療法においては、吸引管や洗浄管の先端をできるだけ患部に近い位置に導いた方が効果的であるが、カバー部材の接続部を介していると接続部の構造や位置が制約になり、吸引管や洗浄管の先端を患部近傍に導くのは難しい。 Patent Documents 1 to 3 describe a negative pressure closure device for negative pressure closure therapy in which the periphery of an affected area is hermetically sealed by an airtight cover member and a sealing means, and the surrounding area of the affected area is negatively charged by a suction tube and a suction means. Has been. InPatent Documents 1 to 3, the suction pipe is connected to a cover member ("Connector 30" inPatent Document 1, "Decompression Connection 92" inPatent Document 2, "Communication Port 41" in Patent Document 3). It is led out from the negative pressure sealing part via. In the negative pressure closing device having such a configuration, it is necessary to increase the air density at the connection portion of the suction pipe provided on the cover member in addition to increasing the air density at the end of the cover member. An attempt to increase the airtightness of the connecting part provided with the cover member inevitably complicates the structure of the connecting part, which is intrusive for the patient and hinders daily activities when wearing negative pressure closure devices for a long time. Occurs. In addition to the suction pipe, when installing a cleaning pipe that supplies cleaning liquid or a pipe that supplies chemical liquid, it is necessary to increase the number of connections each time. This will interfere with long-term wearing. In particular, when used for hand wounds, it is difficult to move the hand while wearing a tool. In negative pressure closure therapy, it is more effective to guide the tip of the suction tube or washing tube as close to the affected area as possible. However, if the cover member is connected, the structure and position of the connection portion are It becomes a limitation and it is difficult to guide the tip of the suction tube or the cleaning tube to the vicinity of the affected part.

非特許文献1〜2は、本願の発明者らの先行技術であり、カバー部材に接続部を設けずに、吸引管等をカバー部材と体表面との間を通して患部に導く技術が記載されている。非特許文献1〜2の技術では、カバー部材に特別に吸引管等の接続部を設ける必要がないため、全体の構造が簡単になり長期着用に適している。しかしながら、吸引管等の固定に一般の医療用片面テープを用いているため、吸引管等の固定に難があるとともに、吸引管等の周辺での気密性にも問題があった。 Non-Patent Documents 1 and 2 are the prior arts of the inventors of the present application, and describe a technique for guiding a suction tube or the like through the space between the cover member and the body surface without providing a connection portion on the cover member. Yes. In the techniques ofNon-Patent Documents 1 and 2, since it is not necessary to provide a connection part such as a suction pipe in the cover member, the entire structure is simplified and suitable for long-term wear. However, since a general medical single-sided tape is used for fixing the suction tube and the like, there is a difficulty in fixing the suction tube and the like, and there is a problem in airtightness around the suction tube and the like.

本発明は上記問題点を解決するためになされたものであり、カバー部材に吸引管等を接続する接続部を設けないで、装着性を向上させた陰圧閉鎖用具を提供することを目的とする。また、患部周辺の気密度を向上させることができる陰圧閉鎖用具を提供することを目的とする。また、装着時に吸引管等の位置決めや固定が容易にできる陰圧閉鎖用具を提供することを目的とする。 The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a negative pressure closing device with improved wearability without providing a connection portion for connecting a suction pipe or the like to a cover member. To do. It is another object of the present invention to provide a negative pressure closure device that can improve the air density around the affected area.

＜第1実施形態＞
図1は、本発明の第1実施形態の陰圧閉鎖用具を表す図である。本陰圧閉鎖用具は、患部を含む手を覆う手袋1（カバー部材）と、医療用片面テープを巻き付けることにより手袋1の開口部を気密状態にするシール手段2と、患部を保護する被覆材3と、外部に設けられた吸引手段11に接続され患部周辺を陰圧にする吸引管4と、同じく外部に設けられた洗浄液供給手段12に接続され患部周辺に洗浄液を供給する洗浄管5（供給管）と、吸引管4及び洗浄管5と手首の体表面との間に設けられた両面テープ6から構成される。<First Embodiment>
FIG. 1 is a diagram illustrating a negative pressure closing device according to a first embodiment of the present invention. This negative pressure closure device includes a glove 1 (cover member) that covers the hand including the affected part, a sealing means 2 that airtights the opening of theglove 1 by wrapping a single-sided medical tape, and a covering material that protects the affected part. 3, asuction tube 4 connected to the suction means 11 provided outside to make negative pressure around the affected area, and acleaning tube 5 connected to the cleaning liquid supply means 12 also provided outside and supplying cleaning liquid around the affected area ( Supply pipe), and a double-sided tape 6 provided between thesuction pipe 4 and thewashing pipe 5 and the body surface of the wrist.

図2は、図1のA-A’断面の断面図である。体表面13のすぐ上には両面テープ6が配置され、その上には吸引管4及び洗浄管5が配置されている。吸引管4及び洗浄管5の上には、これらの管を包み込むように手袋1が配置され、手袋1の上には医療用片面テープからなるシール手段2が配置される。 FIG. 2 is a cross-sectional view of the A-A ′ cross section of FIG. 1. A double-sided tape 6 is disposed immediately above thebody surface 13, and asuction tube 4 and acleaning tube 5 are disposed thereon. Aglove 1 is disposed on thesuction tube 4 and thecleaning tube 5 so as to wrap these tubes, and a sealing means 2 made of a medical single-sided tape is disposed on theglove 1.

図3は、図1のB-B’断面の断面図である。図2と同様に、体表面13のすぐ上には両面テープ6が配置され、その上には吸引管4及び洗浄管5が配置されている。吸引管4及び洗浄管5の上には、これらの管を包み込むように医療用片面テープからなるシール手段2が配置される。 FIG. 3 is a cross-sectional view of the B-B ′ cross section of FIG. 1. As in FIG. 2, the double-sided tape 6 is disposed immediately above thebody surface 13, and thesuction tube 4 and thecleaning tube 5 are disposed thereon. On thesuction tube 4 and thewashing tube 5, a sealing means 2 made of medical single-sided tape is disposed so as to wrap these tubes.

手袋1は、柔軟性を有し、気密性を保持できる材質からなり、例えば、ポリ塩化ビニール、天然ゴムラテックス、ポリエチレン、ポリプロピレン、ポリスチレンなど用いられ得る。シール手段2としては市販の医療用片面テープが好適に用いられ得るが、手袋1の開口部を気密状態にできるものであれば何でも良い。患部を保護する被覆材3は、浸透性や吸収性を持ち、患部を保護できるものであれば、何でも良く、例えば、ポリウレタン、ハイドロコロイド、不織布、ガーゼなどが用いられ得る。吸引管4及び洗浄管5は、空気や体液などを吸引でき洗浄液を供給できるものであれば何でも良く、例えば、ポリイミド、フッ素樹脂、シリコンゴム、ポリ塩化ビニール、ポリエステル、ポリプロピレンなどが用いられ得る。両面テープ6は、両面に粘着層を有しているテープであれば何でも良いが、一般の医療用片面テープと同等の材質及び厚さであることが好ましい。 Theglove 1 is made of a material that has flexibility and can maintain airtightness. For example, polyvinyl chloride, natural rubber latex, polyethylene, polypropylene, polystyrene, or the like can be used. As the sealing means 2, a commercially available single-sided medical tape can be suitably used, but any means can be used as long as the opening of theglove 1 can be airtight. The coveringmaterial 3 for protecting the affected part may be anything as long as it has permeability and absorbability and can protect the affected part. For example, polyurethane, hydrocolloid, non-woven fabric, gauze and the like can be used. Thesuction tube 4 and thecleaning tube 5 may be anything as long as they can suck air or body fluid and supply the cleaning liquid. For example, polyimide, fluororesin, silicon rubber, polyvinyl chloride, polyester, polypropylene, and the like can be used. The double-sided tape 6 may be anything as long as it has an adhesive layer on both sides, but is preferably made of the same material and thickness as a general medical single-sided tape.

吸引管4に接続される吸引手段11は、医療用ポンプなどが用いられる。患部を陰圧にするための吸引は連続的に行っても良いし、必要に応じて間欠的に行っても構わない。洗浄管5に接続される洗浄液供給手段12は洗浄管5に洗浄液を供給するものであるが、患部周辺が陰圧になっているため、洗浄液タンクや洗浄液袋に接続しておくだけでも洗浄液の供給が可能である。また、洗浄管5は、洗浄液の他、薬液等を供給することもできる。 As the suction means 11 connected to thesuction pipe 4, a medical pump or the like is used. Suction for making the affected area negative pressure may be performed continuously or intermittently as necessary. The cleaning liquid supply means 12 connected to thecleaning pipe 5 supplies the cleaning liquid to thecleaning pipe 5, but since the area around the affected area has a negative pressure, the cleaning liquid supply means 12 can be connected only to the cleaning liquid tank or the cleaning liquid bag. Supply is possible. The cleaningtube 5 can also supply a chemical solution and the like in addition to the cleaning solution.

吸引管4及び洗浄管5と体表面13との間に両面テープ6を用いることにより、吸引管4及び洗浄管5周辺での空気漏れが低減され、患部の気密度を向上することができる。例えば、図2における吸引管4及び洗浄管5と手袋1と両面テープ6との接触部14において、手袋1及び両面テープ6の柔軟性と両面テープ6の上部粘着層の効果により、手袋1内部を陰圧にすることで手袋1が両面テープ6に引きつけられ接触部14が気密的に塞がる。同様に、図3における吸引管4及び洗浄管5とシール手段2と両面テープ6との接触部15において、シール手段2及び両面テープ6の柔軟性と両面テープ6の上部粘着層の効果により、手袋1内部を陰圧にすることでシール手段2が両面テープ6に引きつけられ接触部15が気密的に塞がる。 By using the double-sided tape 6 between thesuction tube 4 and thecleaning tube 5 and thebody surface 13, air leakage around thesuction tube 4 and thecleaning tube 5 is reduced, and the air density of the affected part can be improved. For example, in thecontact portion 14 between thesuction tube 4 and thecleaning tube 5, theglove 1 and the double-sided tape 6 in FIG. 2, the inside of theglove 1 is affected by the flexibility of theglove 1 and the double-sided tape 6 and the effect of the upper adhesive layer of the double-sided tape 6. By applying a negative pressure, theglove 1 is attracted to the double-sided tape 6 and thecontact portion 14 is airtightly closed. Similarly, in thecontact portion 15 between thesuction tube 4 and thecleaning tube 5 in FIG. 3 and the sealing means 2 and the double-sided tape 6, due to the flexibility of the sealing means 2 and the double-sided tape 6 and the effect of the upper adhesive layer of the double-sided tape 6, By applying negative pressure to the inside of theglove 1, the sealing means 2 is attracted to the double-sided tape 6, and thecontact portion 15 is airtightly closed.

図4及び図5を用いて本実施形態の陰圧閉鎖用具の装着手順の一例を説明する。図4に示すように、まずは患部に被覆材3を配置する。その後、両面テープ6を手首部に貼付ける。その後、吸引管4及び洗浄管5を両面テープ6に貼付けることで固定する。両面テープ6があることで、吸引管4及び洗浄管5の固定がしやすくなり、患部周辺への位置決めが容易になる。続いて、図5に示すように手袋1を装着する。その後、図1に示すように医療用片面テープからなるシール手段2を手袋1の開口部に巻き付けることで手袋1内を気密状態にする。その後、吸引手段11を駆動して吸引管4を通じて、手袋1内を陰圧にする。手袋1内が陰圧になることで、吸引管4から膿等の体液を排出されると共に、洗浄管5から洗浄液や薬液が供給され、陰圧閉鎖療法により患部の治癒が促進される。 An example of the attachment procedure of the negative pressure closure device of the present embodiment will be described with reference to FIGS. As shown in FIG. 4, the coveringmaterial 3 is first placed on the affected area. Then, a double-sided tape 6 is stuck on the wrist. Thereafter, thesuction tube 4 and thecleaning tube 5 are fixed by being attached to the double-sided tape 6. Since the double-sided tape 6 is provided, thesuction tube 4 and thecleaning tube 5 can be easily fixed, and positioning around the affected area is facilitated. Subsequently,gloves 1 are worn as shown in FIG. Thereafter, as shown in FIG. 1, the inside of theglove 1 is made airtight by wrapping a sealing means 2 made of a single-sided medical tape around the opening of theglove 1. Thereafter, the suction means 11 is driven to make the inside of theglove 1 have a negative pressure through thesuction tube 4. When the inside of theglove 1 has a negative pressure, body fluid such as pus is discharged from thesuction tube 4, and a cleaning solution or a chemical solution is supplied from the cleaningtube 5, and healing of the affected area is promoted by negative pressure closure therapy.

＜第1実施形態の実施結果＞
第1実施形態の実施結果について説明する。吸引管等の固定及び気密性向上に両面テープを用いた本実施形態と、一般の医療用片面テープのみを用いた従来技術（非特許文献1及び2）とを比較した。<Results of implementation of the first embodiment>
An implementation result of the first embodiment will be described. The present embodiment using a double-sided tape for fixing a suction tube or the like and improving airtightness was compared with the prior art (Non-patent Documents 1 and 2) using only a general medical single-sided tape.

本陰圧閉鎖用具のセッティングを、10名の試行者で、本実施形態と従来技術とについてそれぞれ15回ずつ行い、セッティング時間を比較した。その結果、平均セッティング時間が、本実施形態では116.0秒、従来技術では146.6秒であり、本実施形態の方が約30秒短いことがわかった。このことから、本発明の構成を採用することで、装着までのセッティング時間が低減し、セッティングをする者の負担を低減できることがわかる。さらに、セッティングを繰り返して習熟度を高めることにより、セッティング時間を短縮できる。 Setting of this negative pressure closure device was performed 15 times for each of the present embodiment and the prior art by 10 trial persons, and the setting times were compared. As a result, it was found that the average setting time is 116.0 seconds in the present embodiment and 146.6 seconds in the conventional technique, and this embodiment is shorter by about 30 seconds. From this, it can be seen that, by adopting the configuration of the present invention, the setting time until mounting is reduced, and the burden on the person performing the setting can be reduced. Furthermore, setting time can be shortened by repeating the setting to improve the proficiency level.

さらに、吸引管等の周辺での空気漏れ状態を確認するため、本実施形態と従来技術とで陰圧達成度を比較した。試行者数及び試行回数は、セッティング時間の比較と同じである。測定は高精度微差圧計(P26-50kPa, Halstrup-Walcher社製,ドイツ)を使用した。手袋1（カバー部材）と手の間にセンサーを挿入して吸引を行い、手袋内部の圧と大気圧との差圧を測定した。吸引圧の設定は、陰圧閉鎖療法の基準値として汎用されている-125mmHgとした。陰圧達成度-125mmHgは完全な気密状態を意味する。その結果、陰圧達成度が、本実施形態では平均-122.8mmHg、従来技術では平均-116.6mmHgであり、本実施形態の方が6.2mmHgだけ改善しており、目標値の-125mmHgにより近づいた。このことから、本発明の構成を採用することで、吸引管等の周辺での空気漏れを低減でき、陰圧達成度を向上させることができる。 Furthermore, in order to confirm the state of air leakage around the suction pipe or the like, the negative pressure achievement level was compared between this embodiment and the prior art. The number of trial persons and the number of trials are the same as the comparison of setting times. For the measurement, a high-precision differential pressure gauge (P26-50kPa, manufactured by Halstrup-Walcher, Germany) was used. A sensor was inserted between the glove 1 (cover member) and the hand to perform suction, and the pressure difference between the pressure inside the glove and the atmospheric pressure was measured. The suction pressure was set to -125 mmHg, which is widely used as a reference value for negative pressure closure therapy. Negative pressure achievement -125mmHg means perfect airtightness. As a result, the negative pressure achievement degree is -122.8 mmHg on average in this embodiment, and -116.6 mmHg on average in the conventional technique, and this embodiment is improved by 6.2 mmHg, which is closer to the target value of -125 mmHg. . From this, by adopting the configuration of the present invention, it is possible to reduce air leakage around the suction pipe and the like, and to improve the degree of achievement of the negative pressure.
