Abstract
Description
本発明は、呼吸器疾患患者などに酸素を供給するための力ニューラに関する。更に詳細には、圧力変動吸着型酸素濃縮装置あるいは酸素ボンベから供給される酸素ガスを供給する際、両耳にかかるカニューラの加重を分散し、利便性を向上させた酸素供給カニューラを提供するものである。 The present invention relates to a force neuron for supplying oxygen to respiratory disease patients and the like. More specifically, when supplying oxygen gas supplied from a pressure fluctuation adsorption oxygen concentrator or an oxygen cylinder, an oxygen supply cannula with improved convenience by dispersing the weight of the cannula on both ears is provided. It is.
近年喘息、肺気腫症、慢性気管支炎等の呼吸器系疾患に苦しむ患者が増加する傾向にあるが、その最も効果的な治療法の一つとして酸素吸入療法がある。吸入用の酸素ガスは、携帯用の酸素ボンベや空気中から酸素濃縮気体を直接分離する酸素濃縮装置により容易に得ることが出来るようになり、呼吸器疾患治療として在宅酸素吸入療法が次第に普及するようになって来ている。使用者である呼吸器疾患患者は、酸素発生源である酸素濃縮装置あるいは酸素ボンベから、通常、塩化ビニール製の鼻カニューラを介して酸素ガス、酸素濃縮空気を吸入しており、酸素濃縮装置等から繋がるカニューラを両耳に掛ける形で装着し、鼻孔から酸素を吸入している。 In recent years, the number of patients suffering from respiratory diseases such as asthma, emphysema and chronic bronchitis has been increasing. One of the most effective treatments is oxygen inhalation therapy. Oxygen gas for inhalation can be easily obtained by a portable oxygen cylinder or an oxygen concentrator that directly separates the oxygen-enriched gas from the air, and home oxygen inhalation therapy is gradually spreading as a respiratory disease treatment It ’s coming. Respiratory illness patients, who are users, usually inhale oxygen gas and oxygen-enriched air from an oxygen concentrator or oxygen cylinder, which is an oxygen source, through a nasal cannula made of vinyl chloride. Wearing a cannula connected to the ears in both ears, oxygen is inhaled from the nostrils.
酸素吸入療法の結果として患者の活動範囲は広くなり、使用者が作業等で酸素濃縮装置などの酸素発生源から離れて酸素吸入を行う場合が多くなり、長さ２０ｍ近くにも延長チューブを接続して利用する場合があり、カニューラを引き回しながら使用する患者も増えている。使用中のカニューラの折れ曲がり対策として特開平９−６３４号公報には、異形断面を有するカニューラの採用が記載されている。 As a result of oxygen inhalation therapy, the patient's range of activity is widened, and the user often performs oxygen inhalation away from an oxygen source such as an oxygen concentrator for work, etc., and an extension tube is connected to a length of nearly 20 m. The number of patients who use the cannula is increasing. As a countermeasure against bending of a cannula in use, Japanese Patent Application Laid-Open No. 9-634 describes the use of a cannula having a deformed cross section.
また患者は単なる治療目的だけでなく、生活の質（ＱＯＬ）の向上も重要するようになっている。酸素吸入療法を行う患者の外見が、酸素ボンベとチューブで繋がっているイメージの解消が重要視されている中で、特表昭６３−５０１９３１号公報、実開平６−４１７４３号公報、特開２００１−５４５７５号公報には、鼻カニューラを眼鏡フレームに溝等を設けて固定し、眼鏡でカニューラをマスクしながら酸素吸入する装置が記載されている。さらに、リフレッシュ用途としての酸素吸入も行われ、所謂“酸素バー”などでは、ヘッドフォン型の吸入用具や特開２００１−１６１８２２号公報に記載のような首に支持体を掛けるタイプの吸入用具も使用されている。 In addition, patients are becoming more important not only for therapeutic purposes, but also for improving quality of life (QOL). In view of the fact that the appearance of a patient performing oxygen inhalation therapy is connected with an oxygen cylinder and a tube is emphasized, JP-A-63-501931, JP-A-6-41743, JP-A-2001-2001 Japanese Patent No. -54575 describes a device in which a nose cannula is fixed on a spectacle frame by providing a groove or the like, and oxygen is inhaled while masking the cannula with spectacles. Further, oxygen inhalation is also performed as a refresh application, and so-called “oxygen bars” and the like use headphones-type inhalation devices and inhalation devices of a type in which a support is applied to the neck as described in JP-A-2001-161822. Has been.
医療用途に使用される鼻カニューラの多くは塩化ビニール製の軟質チューブを使用し、使用者手前で二股に分かれたチューブを両耳に掛け、鼻孔付近に設けた供給端から酸素を鼻孔内に放出し、患者の呼吸に応じて酸素が吸入される。この際、チューブの柔軟性やチューブ自体の重量は、使用者である患者の作業性、負荷に大きく影響する。酸素吸入療法を行う患者にとっては、移動自体が体力負担となり、導管の重量増加は大きな患者負担となる。これに対してチューブ自体の肉薄化による軽量化、柔軟性の向上、その一方で供給途中でのカニューラ折れやカニューラ潰れによる酸素供給量の減少、停止を回避する為のチューブの異形化など各種の対策がなされている。 Most of the nasal cannula used for medical purposes uses a soft tube made of vinyl chloride, and a tube divided into two branches in front of the user is put on both ears, and oxygen is released into the nostril from the supply end provided near the nostril In response to the patient's breathing, oxygen is inhaled. At this time, the flexibility of the tube and the weight of the tube itself greatly affect the workability and load of the patient who is the user. For patients undergoing oxygen inhalation therapy, the movement itself is a physical burden, and the increase in the weight of the conduit is a large patient burden. In contrast, the tube itself is lighter and thinner, and more flexible, while the cannula is broken during supply and the cannula is crushed, the oxygen supply is reduced, and the tube is deformed to avoid stopping. Measures are being taken.
しかし、患者が移動する限り、患者とカニューラの直接の接点である両耳に対して重量負荷がかかることは避けられず、長時間の使用、特に延長チューブを使用して酸素供給源から離れた場所で使用するような場合には、耳への負荷が大きくなり、時に赤く腫れ痛みを生じる場合もある。患者は耳に当たる部分にガーゼやクッション材を巻いて耳を保護する他、移動時にはチューブを持って移動するしか対応策はなく、耳への負荷の少ないカニューラが望まれている。 However, as long as the patient moves, it is inevitable that a heavy load is applied to both ears, which are the direct contact points between the patient and the cannula. When used in a location, the load on the ear is increased, sometimes causing swelling and redness. In addition to protecting the ear by wrapping the gauze or cushion material around the part that hits the ear, the patient has no choice but to move with a tube when moving, and a cannula with low load on the ear is desired.
本発明は、上記課題を解決する為に見出されたものであり、患者の耳への負荷の少ないカニューラを提供するものである。 The present invention has been found to solve the above-described problems, and provides a cannula with a low load on a patient's ear.
すなわち本願発明は、呼吸用気体発生手段に接続され、使用者に該呼吸用気体発生手段から供給される呼吸用気体を供給するカニューラであり、一端に該呼吸用気体発生手段との接続口、途中に分岐部を備え、分岐部を介して環状に接続されその中間部分に鼻孔へ該呼吸用気体を供給するの開口部を備えたチューブ状部材から構成され、且つ該チューブ状部材に首周囲で支持する為の支持部材を有することを特徴とする呼吸用気体供給カニューラを提供するものである。 That is, the present invention is a cannula connected to a breathing gas generation means and supplying a breathing gas supplied from the breathing gas generation means to a user, and a connection port with the breathing gas generation means at one end, It is composed of a tube-like member provided with a branch part in the middle, and connected annularly through the branch part, and provided with an opening for supplying the breathing gas to the nostril in the middle part, and the tube-like member has a neck circumference The present invention provides a breathing gas supply cannula characterized by having a support member for supporting the above.
また本願発明は、かかる支持部材が環状構造を有し、該カニューラの分岐部及び環状部分の一部を覆い、使用者の首で支持する部材であることを特徴とし、特に該カニューラ部分を覆う部分が中空状の環状形状を有する繊維部材で構成されることを特徴とする呼吸用気体供給カニューラを提供するものである。 Further, the present invention is characterized in that the support member has a ring structure, covers a part of the branch part and the ring part of the cannula, and supports the user's neck, and particularly covers the cannula part. The present invention provides a breathing gas supply cannula characterized in that the portion is composed of a fiber member having a hollow annular shape.
また本願発明は、かかる支持部材が環状に接続されたチューブ部材の２箇所で固定する固定手段を有することを特徴とし、かかる固定手段が該支持手段及び該チューブ状部材を接続するクリップであることを特徴とする呼吸用気体供給カニューラを提供するものである。 The invention of the present application is characterized in that the supporting member has fixing means for fixing at two positions of the annularly connected tube member, and the fixing means is a clip for connecting the supporting means and the tubular member. A breathing gas supply cannula characterized by the above is provided.
本願発明の呼吸用気体供給カニューラは、所謂ネックレス状の支持手段とカニューラを組み合わせることで、カニューラ着用時に両耳に掛かっていたカニューラ本体の重みと背後に接続する酸素などの呼吸用気体の供給源までの間をつなぐ延長チューブの重量をネックレス部分に分散させることができる。分岐して伸びたカニューレの長さをクリップにより調整することにより、カニューラ先端の鼻孔への着脱を容易にすることが可能となる。 The breathing gas supply cannula of the present invention is a combination of a so-called necklace-like support means and a cannula, so that the weight of the cannula body hanging on both ears when wearing the cannula and the supply source of breathing gas such as oxygen connected to the back It is possible to distribute the weight of the extension tube connecting between the necklace portion and the neck portion. By adjusting the length of the branched cannula with a clip, it is possible to easily attach and detach the tip of the cannula to the nostril.
図１は、現在、酸素吸入療法に使用されている酸素供給用の鼻カニューラの模式図であり、ゼオライト等の酸素より窒素を選択的に吸着する吸着材を充填した吸着床に加圧空気を供給し、酸素を分離する圧力変動吸着型の酸素濃縮装置(1)に、塩化ビニール製の鼻カニューラ(2)を接続し、途中の分岐部分(4)で環状なった部分(5)に設けられた開孔部(3)から鼻孔に酸素が供給される。使用者は、かかる鼻カニューラの環状部分を両耳に掛けて開口部(3)を鼻孔下部になるように装着し酸素を吸入する。 FIG. 1 is a schematic diagram of a nasal cannula for oxygen supply currently used for oxygen inhalation therapy. Pressurized air is applied to an adsorption bed filled with an adsorbent that selectively adsorbs nitrogen from oxygen such as zeolite. A pressure fluctuation adsorption type oxygen concentrator (1) that supplies and separates oxygen is connected to a nasal cannula (2) made of vinyl chloride, and provided in a ring-shaped part (5) at the middle branch part (4) Oxygen is supplied to the nostril from the opening (3). The user puts the annular part of the nasal cannula on both ears and wears the opening (3) so as to be at the lower part of the nostril, and inhales oxygen.
これに対して、本願発明のカニューラは、図２に示すように、一端に酸素濃縮装置などの呼吸用気体発生手段との接続口、途中に分岐部を備え、分岐部を介して環状に接続されその中間部分に鼻孔へ該呼吸用気体を供給するの開口部を備えたチューブ状部材から構成される従来型のカニューラに加え、更に該チューブ状部材に首周囲で支持する為の支持部材(6)を有することを特徴とする。これにより患者が移動した際に、カニューラが引っ張られて生じる耳への荷重を首周囲に分散することが出来る。 On the other hand, as shown in FIG. 2, the cannula of the present invention comprises a connection port with a breathing gas generating means such as an oxygen concentrator at one end and a branch part in the middle, and is connected in an annular shape via the branch part. In addition to a conventional cannula composed of a tubular member having an opening for supplying the breathing gas to the nostril in the middle part thereof, a support member for supporting the tubular member around the neck ( 6). As a result, when the patient moves, the load on the ear generated by pulling the cannula can be distributed around the neck.
支持部材の材質、形状は、ファッション性等を考慮して種々の形状を採用することが出来る。図２は、支持部材を中空の環状形状とし、カニューラの分岐部分から環状部分の一部を中空内部を通し、耳の付け根部分からカニューラを取出し両耳に掛ける形状としている。支持部材としては綿などの繊維製品で製造することで患者の皮膚への刺激を抑えると共に、染色などにより被服とのマッチングを取ることも可能である。そのほか支持部材を環状のスプリングとしてそのスプリング内部にカニューラを通すことも可能である。 Various shapes can be adopted as the material and shape of the support member in consideration of fashionability and the like. In FIG. 2, the support member has a hollow annular shape, and a part of the annular portion passes from the branch portion of the cannula through the hollow interior, and the cannula is taken out from the base portion of the ear and is hung on both ears. The support member can be made of a textile product such as cotton, thereby suppressing irritation to the patient's skin and matching with the clothing by dyeing or the like. In addition, it is possible to pass the cannula inside the spring as a support spring.
また別の態様としては、図３に示すような支持部材を両端にリングを設けた組紐(7)や鎖などで構成し、通常のカニューラ環状部分の2箇所で接続固定し、首でカニューラの重量を支持するもの、或いは図４に示すような分岐部分1箇所で接続し、環状の紐(8)などを首に掛けて支持するものなどを採用することも可能である。 As another embodiment, the supporting member as shown in FIG. 3 is composed of a braid (7) having a ring at both ends, a chain or the like, and connected and fixed at two locations in a normal cannula annular portion, and the cannula is fixed at the neck. It is also possible to employ one that supports the weight, or one that is connected at one branch portion as shown in FIG. 4 and that supports an annular string (8) around the neck.
カニューラと呼吸用気体供給源との間に延長チューブを接続した場合、移動のたびにカニューラが外れたり、耳への負荷が大きくなる。図２のカニューラはその支持部材は図5に示すようにネックレス状の構造となり、首回りのカニューラ部分は支持部材の内部に納まり、カニューラチューブは首もとには現れず見えない構造となる。カニューラ部分を更に覆面するため、支持部材を更にカニューラ分岐部分から酸素供給源側に伸ばすことも可能である。 When an extension tube is connected between the cannula and the breathing gas supply source, the cannula is detached or the load on the ear is increased every time it is moved. The cannula of FIG. 2 has a necklace-like structure as shown in FIG. 5, the cannula portion around the neck is housed inside the support member, and the cannula tube does not appear on the neck and cannot be seen. In order to further cover the cannula part, the support member can be further extended from the cannula branch part to the oxygen supply source side.
カニューラ装着時には支持部材と鼻孔までのカニューラ長を微調整する必要がある。そのために図６に示すような、カニューラの環状部分(5)と支持部材(6)との間にグリップ(9)を設ける。両端にリングを設け、各リングにカニューラと支持部材を通す構造をとることで位置を規定すると共に、カニューラ潰れを防止しすると共にカニューラ長を微調整することが出来る。また樹脂製、或いはゴム製とすることにより、カニューラのすべりを防止し、距離の変動を抑えることが出来る。 When the cannula is mounted, it is necessary to finely adjust the cannula length to the support member and the nostril. For this purpose, a grip (9) is provided between the annular portion (5) of the cannula and the support member (6) as shown in FIG. Rings are provided at both ends, and the position can be defined by passing the cannula and the support member through each ring, and cannula crushing can be prevented and the cannula length can be finely adjusted. In addition, by using resin or rubber, cannula slip can be prevented and variation in distance can be suppressed.
