発明の詳細な説明Detailed Description of the Invention

背景
１．技術分野
本開示は、一般に、身体の四肢に適用するための血管治療の分野に関し、より詳細には取外し可能な部分を有する圧迫装置に関する。 Background 1. TECHNICAL FIELD The present disclosure relates generally to the field of vascular therapy for application to a body limb, and more particularly to a compression device having a removable portion.

２．関連技術の説明
深部静脈血栓症（ＤＶＴ）および末梢浮腫等の血塊を形成する病状は、不動状態の患者および同様の人々にとって重大な問題である。このような患者および人々には、手術中の患者、知覚麻痺患者、長期ベッド療養患者他が含まれる。これらの血塊症状は、概して下肢および／または骨盤の深部静脈に発生する。こうした腸骨、大腿、膝窩および脛骨等の静脈は、酸素が減少した血液を心臓へ環流する。これら静脈の血液循環が疾患、負傷または無活動が原因で抑制されると、血液は蓄積つまり鬱血する性向がある。静的な鬱血は、危険な血塊形成にとって格好である。この症状にともなう主要な危険性は心臓血管の循環障害である。最も深刻なのは、血塊断片が剥離して移動することである。肺塞栓は主肺動脈閉塞を形成して生命を脅かす。 2. 2. Description of Related Art Conditions that form blood clots such as deep vein thrombosis (DVT) and peripheral edema are serious problems for immobile patients and similar people. Such patients and people include patients undergoing surgery, patients with numbness, long-term bed care patients and others. These clot symptoms typically occur in the deep veins of the lower limbs and / or pelvis. These veins such as the iliac, femoral, popliteal and tibia circulate oxygen-depleted blood to the heart. When these venous blood circulations are suppressed due to disease, injury or inactivity, blood tends to accumulate or become congested. Static congestion is good for dangerous clot formation. The major risk associated with this condition is cardiovascular circulatory disturbance. The most serious is that the clot fragments peel off and move. Pulmonary embolism forms a main pulmonary artery occlusion and is life threatening.

患者の不動状態にともなう症状およびその結果生じる危険性は、患者の四肢に間歇圧力を加えて血液循環を助けることにより抑制または緩和できる。血液循環を助けるために、ワンピース型パッドおよび圧迫ブーツ等、周知の装置が用いられてきた。例えば、米国特許第６，２９０，６６２号および第６，４９４，８５２号を参照。   Symptoms and resulting risks associated with the patient's immobility can be suppressed or alleviated by applying intermittent pressure to the patient's limbs to assist in blood circulation. Well known devices such as one-piece pads and compression boots have been used to assist in blood circulation. See, for example, US Pat. Nos. 6,290,662 and 6,494,852.

例えば、空気チューブ等の一連の流体導管による使い捨て巻き付けパッドに接続した空気ポンプからなる順次圧迫装置がこれまで用いられてきた。この巻き付けパッドは、患者の脚の廻りに配置される。次に、巻き付けパッドの異なる各部に順次、強制的に空気を送って、ふくらはぎ廻りに圧力を生みだし、静脈環流を改善する。   For example, sequential compression devices consisting of an air pump connected to a disposable wrap pad by a series of fluid conduits such as air tubes have been used. This wrapping pad is placed around the patient's leg. Next, the air is forcibly sent sequentially to different parts of the winding pad to create pressure around the calf and improve venous perfusion.

これら周知の装置は、嵩張って使用が面倒であることに起因する様々な欠点を持っている。これらの欠点は、快適性、順応性を減じ、術後回復時の患者の移動性を妨げるという点で不利である。   These known devices have various disadvantages due to their bulkiness and cumbersome use. These disadvantages are disadvantageous in that they reduce comfort, adaptability, and hinder patient mobility during postoperative recovery.

従って、極めて望ましいのは、嵩張らず、かつ使用法が簡便で、患者にとっての快適性および順応性を改善した予防的順次圧迫装置により、従来技術の不利な点や欠点を克服することである。予防的順次圧迫装置に取外し可能部分を含んで、本開示の利点を達成するのが望ましい。予防的順次圧迫装置が、加圧流体源からの迅速（クイック）抜去を容易にする弁コネクタを有するなら、更に望ましい。予防的順次圧迫装置は、簡単かつ効率的に製造できるよう意図されている。   Therefore, it would be highly desirable to overcome the disadvantages and drawbacks of the prior art with a prophylactic sequential compression device that is not bulky, simple to use, and has improved patient comfort and conformability. It is desirable to include a removable portion on the prophylactic sequential compression device to achieve the benefits of the present disclosure. It would be further desirable if the prophylactic sequential compression device had a valve connector that facilitated quick removal from a pressurized fluid source. The preventive sequential compression device is intended to be simple and efficient to manufacture.

概要
従って、従来技術の不利な点および欠点を克服するために、嵩張らず、かつ使用を簡便にして、患者にとっての快適性および順応性を改善した圧迫装置が提供される。望ましくは、本圧迫装置に取外し可能部分を含めて本開示の利点を達成する。最も望ましくは、本圧迫装置が、加圧流体源からの迅速抜去を容易にする弁コネクタを有する。本圧迫装置は簡単かつ効率的に製造できる。 SUMMARY Accordingly, in order to overcome the disadvantages and drawbacks of the prior art, a compression device is provided that is not bulky and simple to use, improving patient comfort and conformability. Desirably, the compression device includes a removable portion to achieve the benefits of the present disclosure. Most desirably, the compression device has a valve connector that facilitates rapid removal from a pressurized fluid source. The compression device can be manufactured easily and efficiently.

本開示の原理による圧迫装置には、大腿部のブラッダを引き裂くか、さもなければ取り外し、大腿部ブラッダの接続を空気供給ラインから外すことにより膝の長さのスリーブに切り換えることができる、大腿部の長さの圧迫スリーブが含まれる。一実施の形態では、大腿部のブラッダ空気供給ラインは、大腿部のブラッダと併せて容易に取り外すことができ、大腿部のブラッダがスリーブから取り外される部位またはその近傍に取り付けられる。これにより、大腿部のブラッダおよび大腿部のブラッダ供給ラインをともに取り外すことが一つの動きで達成できる。互換性スリーブにより、ＤＶＴの危険性が術後に減少するので、より快適なスリーブ（膝部対大腿部）を患者は用いることができる。これにより、単一装置を使いながら、治療士に様々な選択肢を提供する。   The compression device according to the principles of the present disclosure can be switched to a sleeve of knee length by tearing or otherwise removing the thigh bladder and disconnecting the thigh bladder from the air supply line. A thigh length compression sleeve is included. In one embodiment, the thigh bladder air supply line can be easily removed in conjunction with the thigh bladder and is attached at or near the site where the thigh bladder is removed from the sleeve. Thus, it is possible to remove both the thigh bladder and the thigh bladder supply line with one movement. The interchangeable sleeve allows the patient to use a more comfortable sleeve (knee versus thigh) since the risk of DVT is reduced post-operatively. This provides a variety of options for the therapist while using a single device.

別の実施の形態では、長期に亘って装置を着用している間の患者への順応性および快適性を改善するために、圧迫装置は穿孔されている。装置は、移動式および／または固定式圧迫システムの両方で用いることができるよう意図されている。加圧流体源は、弁の取外し後も加圧流体を配送し続ける。加圧流体源はチューブのもつれがある場合は大きな警告音で、チューブに洩れがある場合は小さな警告音で報知する。圧迫装置は、スリーブの３部分に対応したチューブを通じて圧力を増加することによって順次作動される。遠位端部は足首部ブラッダ（高圧）、近位端部は大腿部ブラッダ（低圧）である。加圧流体源は、１１秒間加圧して残り時間は減圧するという６０秒サイクルで、スリーブへ空気を圧送する。   In another embodiment, the compression device is perforated to improve patient compliance and comfort while wearing the device over time. The device is intended to be used with both mobile and / or fixed compression systems. The source of pressurized fluid continues to deliver pressurized fluid after the valve is removed. The pressurized fluid source is notified with a loud warning sound when the tube is tangled and with a small warning sound when the tube is leaked. The compression device is activated sequentially by increasing the pressure through a tube corresponding to the three parts of the sleeve. The distal end is an ankle bladder (high pressure) and the proximal end is a thigh bladder (low pressure). The pressurized fluid source pumps air to the sleeve in a 60 second cycle of pressurizing for 11 seconds and reducing the remaining time.

一実施の形態では、本開示の原理による圧迫装置が、四肢廻りへ配置可能に構成されるスリーブを含む。スリーブは、第１拡張チャンバを画成する第１部分と、第２拡張チャンバおよび第３拡張チャンバを画成する第２部分とを含む。第２部分は、加圧流体源、第１拡張チャンバ、第２拡張チャンバおよび第３拡張チャンバに流体連通するコネクタを含み、それにより加圧流体源と各チャンバとの間の流体連通が容易になる。第１部分は第２部分から取り外すことができる。   In one embodiment, a compression device according to the principles of the present disclosure includes a sleeve that is configured to be deployable about a limb. The sleeve includes a first portion that defines a first expansion chamber and a second portion that defines a second expansion chamber and a third expansion chamber.

The at least one opening can include an opening formed in the surface of the expansion chamber. The at least one opening may include a slit disposed between the second expansion chamber and the third expansion chamber.

コネクタはチューブ通路を介してチャンバと連通できる。第１拡張チャンバのチューブ通路はコネクタから取り外せる。加圧流体は、順次に時間間隔をずらしてチャンバを拡張させるようにチャンバへ配送できるので、例えば、第１拡張チャンバが拡張し、続いて（２．５秒後に）第２拡張チャンバ、（３秒後に）第３拡張チャンバが、第１拡張チャンバの開始から合計１１秒までに拡張する。次いで、チャンバ全てが同時に大気圧へ排気される。   The connector can communicate with the chamber via a tube passage. The tube passage of the first expansion chamber can be removed from the connector. Pressurized fluid can be delivered to the chamber in such a way as to expand the chamber at sequential time intervals, so that, for example, the first expansion chamber expands, followed by (after 2.5 seconds) the second expansion chamber, (3 After 3 seconds, the third expansion chamber expands to a total of 11 seconds from the start of the first expansion chamber. The entire chamber is then evacuated to atmospheric pressure at the same time.

以下の説明には、圧迫装置の説明、続いて、本開示の原理による圧迫装置を操作する例示の方法の説明が含まれる。付帯の図で説明する例示の実施の形態および開示への参照を詳細に行う。   The following description includes a description of the compression device, followed by a description of an exemplary method of operating the compression device according to the principles of the present disclosure. Reference will now be made in detail to the exemplary embodiments and disclosure, which are illustrated in the accompanying figures.

図では、幾つかの図の全体に亘って、同じ要素は同じ符号で指定する。最初に、本開示の原理により構築した予防的順次圧迫装置１０を示す図１および図２を参照する。圧迫装置１０は、例えば、対象者の身体の脚Ｌ（図４〜図６）等の、四肢廻りへ配置可能に構成されたスリーブ１２を含む。スリーブ１２、および圧迫装置１０の他の部分は、対象者の身体の、例えば脚、腕のような様々な四肢、手足等に配置され、巻き付けられ、取り付けられるものでもよい、ということが意図される。   In the figures, like elements are designated by like numerals throughout the several views. Reference is first made to FIGS. 1 and 2 illustrating a prophylactic sequential compression device 10 constructed in accordance with the principles of the present disclosure. The compression device 10 includes, for example, a sleeve 12 configured to be arranged around the extremities, such as a leg L (FIGS. 4 to 6) of the subject's body. It is contemplated that the sleeve 12 and other portions of the compression device 10 may be placed, wrapped and attached to various limbs, limbs, etc. of the subject's body, for example legs, arms. The

スリーブ１２は、例えば大腿部分１４のような第１部分を含む。第１部分は、例えば第１膨張チャンバ１６のような第１拡張チャンバを画成する。スリーブ１２の第２部分１８は、例えば、第２膨張チャンバ２０のような第２拡張チャンバ、および、例えば第３膨張チャンバ２２のような第３拡張チャンバを画成する。第１部分１４および第２部分１８は、一つまたは複数の拡張チャンバを含むことができる。更に、スリーブ１２またはその部分は使い捨てでもよいことが想定される。   The sleeve 12 includes a first portion, such as a thigh portion 14. The first portion defines a first expansion chamber, such as the first expansion chamber 16. The second portion 18 of the sleeve 12 defines a second expansion chamber, such as the second expansion chamber 20, and a third expansion chamber, such as the third expansion chamber 22, for example. The first portion 14 and the second portion 18 can include one or more expansion chambers. It is further envisioned that the sleeve 12 or portions thereof may be disposable.

第２部分１８は、第２膨張チャンバ２０を含むふくらはぎ部分２４、および第３膨張チャンバ２２を含む足首部分２６を有する。第１部分および第２部分１８は、対象者の四肢の様々な部分へ、特定の血管治療適用の要件に従って配置してもよいことが意図される。後述するように、足首部分２６には、弁コネクタ２８およびチューブ６２（図４Ｃおよび図４Ｄ）を介して加圧流体源３０と流体連通するとともに、チューブを含む流体通路を介してチャンバ１６、２０、２２にも流体連通する弁コネクタ６４が含まれる（例えば、全内容を引用して本明細書に組み込んだ、２００４年２月２３日出願の米国特許出願第１０／７８４，６３９号、発明の名称「流体導管コネクタ装置」に記載の弁コネクタを参照。）。チューブ６２は３本の分離したチューブまたは管腔６５Ａ、６５Ｂ、６５Ｃからできている。この構成により、加圧流体３０と、チャンバ１６、２０、２２との間の流体連通が容易になる。   The second portion 18 has a calf portion 24 that includes a second expansion chamber 20 and an ankle portion 26 that includes a third expansion chamber 22. It is contemplated that the first and second portions 18 may be placed on various portions of the subject's limb according to the requirements of a particular vascular treatment application. As will be described below, the ankle portion 26 is in fluid communication with a pressurized fluid source 30 via a valve connector 28 and a tube 62 (FIGS. 4C and 4D), and chambers 16, 20 via fluid passages including tubes. , 22 also includes a valve connector 64 in fluid communication (eg, US patent application Ser. No. 10 / 784,639, filed Feb. 23, 2004, incorporated herein by reference in its entirety). (Refer to the valve connector in the name "fluid conduit connector device".) Tube 62 is made up of three separate tubes or lumens 65A, 65B, 65C. This configuration facilitates fluid communication between the pressurized fluid 30 and the chambers 16, 20, 22.

大腿部分１４は第２部分１８から取外し可能である。例えば、ふくらはぎ部分２４は、穿孔付アタッチメント３２を介して大腿部分１４へ取外し可能に接続する。この取外し可能な構成は、簡易な操作により圧迫装置１０が嵩張るのを軽減し、対象者への快適性および順応性を高める利点をもつ。圧迫装置１０は、対象者に十分な移動性も提供する。スリーブ１２には、使用中の四肢の移動を容易にする弾性材料またはスパンデックス材料等のフレキシブルな区域を、部分間に配置して含めてもよいことが意図される。   The thigh portion 14 is removable from the second portion 18. For example, the calf portion 24 is removably connected to the thigh portion 14 via a perforated attachment 32. This removable configuration has the advantage of reducing the bulkiness of the compression device 10 by a simple operation and increasing the comfort and adaptability to the subject. The compression device 10 also provides sufficient mobility for the subject. It is contemplated that the sleeve 12 may include a flexible area, such as an elastic material or spandex material, that facilitates movement of the limb during use, disposed between the portions.

図１および図２で最もよくわかるように、スリーブ１２には、重ね合わせてスリーブを形成する上部シート３４および下部シート３６が含まれる。上部シート３４および下部シート３６は、膨張チャンバ１６、２０、２２を画成するシーム部で接合して固定する。シーム部３８はチャンバ１６を画成し、シーム部４０はチャンバ２０を画成し、そしてシーム部４２はチャンバ２２を画成する。エッジ部４４は、シーム部３８、４０、４２を越えてスリーブ１２の廻りに延びる。意図する点は、スリーブ１２には、その周囲に様々に配置される、上部シート３４および下部シート３６を接合する複数のシーム部が含まれる。シーム部は、溶着や、縫合や、接着による形成や、熱シール等で処理されてもよい、ということも意図される。   As best seen in FIGS. 1 and 2, the sleeve 12 includes an upper sheet 34 and a lower sheet 36 that overlap to form the sleeve. The upper sheet 34 and the lower sheet 36 are joined and fixed at seams that define the expansion chambers 16, 20, 22. Seam portion 38 defines chamber 16, seam portion 40 defines chamber 20, and seam portion 42 defines chamber 22. The edge portion 44 extends around the sleeve 12 beyond the seam portions 38, 40, 42. It is intended that the sleeve 12 includes a plurality of seams that join the upper sheet 34 and the lower sheet 36 that are variously disposed around the sleeve 12. It is also intended that the seam portion may be processed by welding, stitching, formation by adhesion, heat sealing, or the like.

上部シート３４および下部シート３６は特定の血管治療適用に応じて、および／または好みに応じて、ＰＶＣ（ポリ塩化ビニル）およびＰＥ（ポリエチレン）のような、例えば、フィルム、織物等の、チャンバ１６、２０、２２の膨張に適した材料で製作される。ウレタンおよびシリコン等の、半フレキシブルおよびフレキシブル織物を用いてもよい。スリーブ１２は、チャンバ１６、２０、２２を含み、シート３４、３６とともに配置されるか、またはシート３４、３６に取り付けられる分離構造を含むことができる。しかしながら、従来技術に精通する者には言うまでもなく、本開示に基づく組立ておよび製造に適する他の材料および製造方法であってもよい。   The upper sheet 34 and lower sheet 36 may be a chamber 16 such as a film, fabric, etc., such as PVC (polyvinyl chloride) and PE (polyethylene), depending on the particular vascular treatment application and / or preference. , 20, 22 made of a material suitable for expansion. Semi-flexible and flexible fabrics such as urethane and silicone may be used. The sleeve 12 includes chambers 16, 20, 22 and can include a separation structure disposed with or attached to the sheets 34, 36. However, it will be appreciated by those skilled in the art that other materials and methods suitable for assembly and manufacture according to the present disclosure may be used.

スリーブ１２は対象者の四肢に隣接する部分に、冷却作用を提供する、例えばスリーブ孔４６等の排気開口部を画成する。スリーブ孔４６は、上部シート３４および下部シート３６を完全に貫通する。これにより、対象者の使用中の快適さが改善される。スリーブ１２には、スリーブ孔４６を囲んで、それぞれのチャンバを孔からシールして絶ち、その間の流体連通を防ぐ溶着部分４８が含まれる。スリーブ１２は、冷却作用を提供する排気孔４７も含む。スリーブ１２は、その周辺に様々に配置される複数の排気開口部を含んでもよいことが想定される。   The sleeve 12 defines an exhaust opening, such as a sleeve hole 46, which provides a cooling action in a portion adjacent to the subject's limb. The sleeve hole 46 completely penetrates the upper sheet 34 and the lower sheet 36. This improves the comfort of the subject during use. The sleeve 12 includes a welded portion 48 that surrounds the sleeve holes 46 and seals the respective chambers away from the holes to prevent fluid communication therebetween. The sleeve 12 also includes an exhaust hole 47 that provides a cooling action. It is envisioned that the sleeve 12 may include a plurality of exhaust openings that are variously disposed around its periphery.

例えば、排気スリット５０のような排気開口部を、膨張チャンバ２０と膨張チャンバ２２との間に配置する。排気スリット５０は、上部シート３４および下部シート３６を完全に貫通する。排気スリットは対象者に冷却効果を提供し、使用中のふくらはぎおよび足首の移動性を増大する利点をもつ。排気スリット５０は様々な長さであってもよいことが意図される。   For example, an exhaust opening such as an exhaust slit 50 is disposed between the expansion chamber 20 and the expansion chamber 22. The exhaust slit 50 completely penetrates the upper sheet 34 and the lower sheet 36. The exhaust slit provides a cooling effect to the subject and has the advantage of increasing calf and ankle mobility during use. It is contemplated that the exhaust slit 50 may be of various lengths.

大腿部分１４は、膨張チャンバ１６のサブチャンバ５４を画成するスポット溶着部５２の軸方向ラインを含む。同様に、ふくらはぎ部分２４は、膨張チャンバ２０のサブチャンバ５６を画成するスポット溶着部５４の軸方向ラインを含み、足首部分２６は、膨張チャンバ２２のサブチャンバ６０を画成するスポット溶着部５８を含む。想定では、サブチャンバは、代替として、連続した溶着、接着、ホットシール等により形成してもよい。想定では更に、溶着部５８を多様な配向で配置してサブチャンバの代替構成を創出してもよい。   The thigh portion 14 includes an axial line of a spot weld 52 that defines a subchamber 54 of the expansion chamber 16. Similarly, the calf portion 24 includes the axial line of the spot weld 54 that defines the subchamber 56 of the expansion chamber 20, and the ankle portion 26 the spot weld 58 that defines the subchamber 60 of the expansion chamber 22. including. Assuming that the sub-chamber may alternatively be formed by continuous welding, bonding, hot sealing, and the like. It is further envisaged that the welds 58 may be arranged in various orientations to create alternative sub-chamber configurations.

弁コネクタ２８は、流体通路を介してチャンバ１６、２０、２２に連通する。流体通路には、ポンプを含むこともある加圧流体源３０へ弁コネクタ２８を接続するチューブ６２が含まれる（例えば、全内容を引用して本明細書に組み込まれた、２００４年２月２３日出願の米国特許出願第１０／７８４，３２３号、発明の名称「圧迫処置システム」、に記載のコントローラーポンプを参照）。加圧流体源３０は、固定式でも可搬式でもよい。加圧流体源３０は、本開示の原理にしたがった血液治療を実行するために、必要な電子回路、コンピューターソフトウエア他を含むものとしてもよい。   The valve connector 28 communicates with the chambers 16, 20, 22 via fluid passages. The fluid passage includes a tube 62 that connects the valve connector 28 to a pressurized fluid source 30, which may include a pump (eg, February 23, 2004, incorporated herein by reference in its entirety). (See the controller pump described in US patent application Ser. No. 10 / 784,323, filed Japanese Patent Application, entitled “Pressure Treatment System”). The pressurized fluid source 30 may be fixed or portable. Pressurized fluid source 30 may include the necessary electronic circuitry, computer software, etc., to perform blood treatment according to the principles of the present disclosure.

チューブ６２は、図３に示すように、カプラー６４を介して弁コネクタ２８に取り付けられる。チューブ６６は弁コネクタ２８から延びて膨張チャンバ２０に流体接続する。チューブ６７は弁コネクタ２８から延びて膨張チャンバ２２に流体接続する。チューブ６８は弁コネクタ２８から延びて膨張チャンバ１６に流体接続する。チューブ６８は迅速抜去ポート７０を含む。ポート７０は、弁コネクタ２８に取り付けられており、簡単に取り外してふくらはぎ部分２４からの大腿部分１４の取外しを容易にする。チューブ６２および管腔６５Ａ、６５Ｂ、６５Ｃは、チューブ６７、６６、６８にそれぞれ対応する。想定では、弁コネクタ２８を、脱着可能なつなぎ止め等でスリーブ１２に固定できる。更に、ポート７０を弁コネクタ２８に固定でき、チューブ６８は大腿部分１４から取外し可能であることも想定される。   The tube 62 is attached to the valve connector 28 via a coupler 64 as shown in FIG. A tube 66 extends from the valve connector 28 and fluidly connects to the expansion chamber 20. A tube 67 extends from the valve connector 28 and fluidly connects to the expansion chamber 22. A tube 68 extends from the valve connector 28 and fluidly connects to the expansion chamber 16. Tube 68 includes a quick removal port 70. The port 70 is attached to the valve connector 28 and is easily removed to facilitate removal of the thigh portion 14 from the calf portion 24. Tube 62 and lumens 65A, 65B, and 65C correspond to tubes 67, 66, and 68, respectively. It is assumed that the valve connector 28 can be fixed to the sleeve 12 by a detachable tether or the like. It is further envisioned that the port 70 can be secured to the valve connector 28 and the tube 68 can be removed from the thigh portion 14.

スリーブ１２は、例えば、対応するフックループパッド（マジックテープ（登録商標））７４と係合させる方向に取り付けたフックループパッド７２等の、締め付け部品を含む。フックループパッド７２、７４は、スリーブ１２の対象者の脚Ｌへの取り付けを確実にできる。一つまたは複数の締め付け部品をスリーブ１２廻りに様々に配置できることが意図される。更に、締め付け部品は、例えば、クリップ、接着剤、ピン等を含めてもよいことが意図される。   The sleeve 12 includes a fastening component such as a hook loop pad 72 attached in a direction to be engaged with a corresponding hook loop pad (magic tape (registered trademark)) 74. The hook loop pads 72 and 74 can ensure the attachment of the sleeve 12 to the leg L of the subject. It is contemplated that one or more clamping parts can be variously arranged around the sleeve 12. Further, it is contemplated that the clamping component may include, for example, a clip, an adhesive, a pin, and the like.

図４〜図７を参照する。上記説明と類似した圧迫装置１０が、使用するために組立て、消毒、および梱包されている。使用に際しては、圧迫装置１０を、対象者の脚Ｌ廻りに配置するように準備し、操作する。チューブ６６をふくらはぎ部分２４に接続し、チューブ６７を足首部分２６と接続する。チューブ６８は大腿部分１４に接続する。チューブ６６、６７、６８は、弁コネクタ２８に接続される。弁コネクタ２８はチューブ６２および加圧流体源３０に接続される（図４Ｃおよび図４Ｄ）。従って、圧迫装置１０の流体通路は、加圧流体源３０と、チャンバ１６、２０、２２との間の流体連通を達成する。   Reference is made to FIGS. A compression device 10 similar to that described above is assembled, disinfected and packaged for use. In use, the compression device 10 is prepared and operated so as to be arranged around the leg L of the subject. Tube 66 is connected to calf portion 24 and tube 67 is connected to ankle portion 26. Tube 68 connects to thigh portion 14. Tubes 66, 67, 68 are connected to valve connector 28. Valve connector 28 is connected to tube 62 and pressurized fluid source 30 (FIGS. 4C and 4D). Accordingly, the fluid passage of the compression device 10 achieves fluid communication between the pressurized fluid source 30 and the chambers 16, 20, 22.

図４Ａおよび図４Ｂに示すように、スリーブ１２で脚Ｌ廻りを包み込み、フックループパッド７２、７４を介してそこに固定される。スリーブ１２は、第２部分１８を介して脚Ｌの膝下から、大腿部分１４を介して膝の上までの長さに延びる。圧迫装置１０は、流体通路を介してチャンバ１６、２０、２２へ加圧流体を配送することにより順次に作動する。一実施の形態では、図７に示すように、加圧流体源３０は、加圧１１秒、減圧４９秒を含む６０秒サイクルで、スリーブ１２へ空気を配送する。膨張チャンバ２２に加圧空気を２．５秒間配送する。次いで、膨張チャンバ２０に加圧空気を２．５秒間配送する。次いで、膨張チャンバ１６に加圧空気を２．５秒間配送する。圧迫装置１０を１１秒までの間膨張を維持し、次いで、チャンバ１６、２０、２２を同時に収縮させる。この順次加圧は、特定の血管治療適用の要件に従って、複数サイクルの間継続できることが意図される。他の順次加圧サイクルも意図される。例えば、液体、気体等の様々な形の流体をスリーブ１２へ配送できることが想定される。   As shown in FIGS. 4A and 4B, the sleeve 12 wraps around the leg L and is fixed thereto via hook loop pads 72 and 74. The sleeve 12 extends from the lower part of the leg L through the second part 18 to the upper part of the knee through the thigh part 14. The compression device 10 operates sequentially by delivering pressurized fluid to the chambers 16, 20, 22 via fluid passages. In one embodiment, as shown in FIG. 7, the pressurized fluid source 30 delivers air to the sleeve 12 in a 60 second cycle that includes 11 seconds of pressurization and 49 seconds of depressurization. Deliver pressurized air to the expansion chamber 22 for 2.5 seconds. The pressurized air is then delivered to the expansion chamber 20 for 2.5 seconds. The pressurized air is then delivered to the expansion chamber 16 for 2.5 seconds. The compression device 10 is kept inflated for up to 11 seconds, and then the chambers 16, 20, and 22 are deflated simultaneously. It is contemplated that this sequential pressurization can be continued for multiple cycles according to the requirements of the particular vascular treatment application. Other sequential pressurization cycles are also contemplated. For example, it is envisaged that various forms of fluid, such as liquid or gas, can be delivered to the sleeve 12.

順次加圧の所望の時間、例えば特定の血管治療適用の要件に従う回復時間等、が経過した後、大腿部分１４は、第２部分１８から取り外してもよい。従って、スリーブ１２は、膝下から膝上まで延びる長さから、膝下だけに延びる長さに切り換えることができる。スリーブ１２は、図６Ａおよび図６Ｂに示すように、穿孔部３２を介して、大腿部分１４をふくらはぎ部分２４から引き裂いて取り外すように操作される。チューブ６８に接続するポート７０は、図５Ｂに示すように、容易な操作で弁コネクタ２８から迅速に抜去できる。ふくらはぎ部分２４および足首部分２６を含むスリーブ１２の残りの部分は、単独で上記した動作を継続する。これにより、スリーブ１２は、脚の長さ全体の装置から膝の長さの装置に切り換えられる。圧迫装置１０は、所望の血管治療適用を完了させるために利用することができる。他の使用方法、例えば大腿部分１４を取り外さず、スリーブ１２に残すことも意図されている。   The thigh portion 14 may be removed from the second portion 18 after a desired time of sequential pressurization has elapsed, such as a recovery time according to the requirements of a particular vascular treatment application. Therefore, the sleeve 12 can be switched from a length extending from below the knee to above the knee to a length extending only below the knee. The sleeve 12 is manipulated to tear and remove the thigh portion 14 from the calf portion 24 through the perforated portion 32 as shown in FIGS. 6A and 6B. The port 70 connected to the tube 68 can be quickly removed from the valve connector 28 with an easy operation, as shown in FIG. 5B. The remaining portion of the sleeve 12, including the calf portion 24 and the ankle portion 26, continues the operation described above alone. This allows the sleeve 12 to be switched from a device with full leg length to a device with knee length. The compression device 10 can be utilized to complete a desired vascular treatment application. Other uses are also contemplated, such as leaving the thigh portion 14 in the sleeve 12 without removal.

上記のように、大腿部分１４を任意に取り外すにあたり、ユーザーまたは治療士は、チューブ材６８の接続を外し、コネクタ２８からポート７０の接続を外す。コネクタ２８（および任意で接続を外されるポート７０）は、チューブ６８をコネクタ２８から分離した時でも、流体源３０から所望の流量の流体がコネクタ２８を通って達成されたままになるように構成される。このような継続した流れは、加圧流体源３０による連続性を維持するのに好ましい。つまり、ユーザーまたは治療士が、圧迫装置１０から大腿部分１４を取り外すことを決めた場合に、流体源３０に流量調整を行わなくてもよい。大腿部分１４を取り外した後でも、加圧流体源３０は、コネクタ２８にチューブ６５Ｃを通じて同一の流量および圧力を配送し、大気に放出し続ける。   As described above, in removing the thigh portion 14 arbitrarily, the user or therapist disconnects the tube material 68 and disconnects the port 70 from the connector 28. Connector 28 (and optionally disconnected port 70) ensures that a desired flow rate of fluid from fluid source 30 is achieved through connector 28 even when tube 68 is disconnected from connector 28. Composed. Such a continuous flow is preferred to maintain continuity with the pressurized fluid source 30. That is, if the user or the therapist decides to remove the thigh portion 14 from the compression device 10, the fluid source 30 may not be adjusted in flow rate. Even after the thigh portion 14 is removed, the pressurized fluid source 30 delivers the same flow rate and pressure to the connector 28 through the tube 65C and continues to release to the atmosphere.

図８を参照して、圧迫装置１０の代替の実施の形態を示す。上記の場合と同様に、スリーブ１２は、大腿部分１４および第２部分１１８を含む。第２部分１１８は、膨張チャンバ１２２を含むふくらはぎ部分１２４および足首部分１２６を有する。加圧流体源３０（図１）は、弁コネクタ２８およびチューブ６２（図１）を介して、スリーブ１２と流体連通する。上記の場合と同様に、穿孔部分３２を介した大腿部分１４のオプションの取り外しを含めて使用するために、弁コネクタ２８は、別々のチューブ６８および１６６を介して、チャンバ１６および１２２とそれぞれ流体連通する。   Referring to FIG. 8, an alternative embodiment of the compression device 10 is shown. As in the above case, the sleeve 12 includes a thigh portion 14 and a second portion 118. The second portion 118 has a calf portion 124 that includes an expansion chamber 122 and an ankle portion 126. Pressurized fluid source 30 (FIG. 1) is in fluid communication with sleeve 12 via valve connector 28 and tube 62 (FIG. 1). As above, for use, including optional removal of the femoral portion 14 via the pierced portion 32, the valve connector 28 is fluidly connected to the chambers 16 and 122 via separate tubes 68 and 166, respectively. Communicate.
