Description
本発明は、酸素富化ガスを吸入する為の吸入用具に関する。更に詳細には、起床時および就寝時において、顔面部への圧迫なしに酸素富化ガス吸入を行うことを実現する酸素富化ガス供給用具に関するものである。 The present invention relates to an inhalation device for inhaling oxygen-enriched gas. More specifically, the present invention relates to an oxygen-enriched gas supply device that realizes inhalation of oxygen-enriched gas without being pressed on the face when waking up and at bedtime.
慢性呼吸器疾患患者などが在宅酸素吸入療法を行う場合には、吸着型酸素濃縮器や酸素ボンベから供給される酸素富化ガスを吸入する際には、多くの場合には供給用具として鼻孔カニューラが使用されている。かかる供給用具は、鼻孔カニューラの供給端部に設けられた鼻部分岐管やカニューラ先端部を直接患者の鼻腔内に挿入する方式が採用されている。鼻孔カニューラはシンプルな形状の酸素富化ガス投与具であり、使い易く安価であるなど、長期酸素療法に適した供給用具である。その一方で以下のような不利益な点を含んでいる。
１．酸素富化ガス供給チューブ固定による皮膚圧迫
２．就寝時における酸素富化ガス供給チューブの巻き付き，捩れ
When patients with chronic respiratory illness perform home oxygen inhalation therapy, when inhaling oxygen-enriched gas supplied from an adsorption-type oxygen concentrator or oxygen cylinder, in many cases, a nostril cannula is used as a supply device. Is used. Such a supply device employs a system in which a nasal branch tube provided at the supply end of the nostril cannula or the tip of the cannula is directly inserted into the nasal cavity of the patient. The nostril cannula is a simple-form oxygen-enriched gas administration device, and is a supply device suitable for long-term oxygen therapy because it is easy to use and inexpensive. On the other hand, it includes the following disadvantages.
1. 1. Skin compression by fixing oxygen-enriched gas supply tube Winding or twisting of oxygen-enriched gas supply tube at bedtime
上記の不利益を解決する態様例として、特表２００３−５３３２９６号公報には、ヘッドセット型の支持体により酸素富化ガス供給チューブを固定して酸素投与する供給用具が開示されている。この供給用具では、酸素富化ガス供給チューブを使用者の頬との接触無しに保持することが可能なことから、頬への圧迫による不快感は無く、かつ通気性が高いため、汗蒸れを起こさずに酸素投与が可能となる。しかしながら、ヘッドセット端から鼻口付近へ向かって伸びた酸素富化ガス供給チューブを固定するアーム部は頬近辺に位置し、就寝時に寝返りをうつなどして頭部を横に向けるとアーム部が頬を圧迫することになる。また酸素富化ガス供給チューブが身体付近を這うため、身体を動かした際に酸素富化ガス供給チューブが身体により押し潰され、あるいはチューブが引っ張られることによるヘッドセットの外れなどのリスクを伴う。 As an example of an embodiment that solves the above disadvantages, Japanese Patent Publication No. 2003-533296 discloses a supply device that administers oxygen by fixing an oxygen-enriched gas supply tube with a headset-type support. With this supply device, it is possible to hold the oxygen-enriched gas supply tube without contact with the user's cheek, so there is no discomfort due to pressure on the cheek and the breathability is high. Oxygen can be administered without causing it. However, the arm part that fixes the oxygen-enriched gas supply tube extending from the end of the headset toward the nostril is located near the cheeks. It will press the cheeks. In addition, since the oxygen-enriched gas supply tube crawls around the body, there is a risk that the oxygen-enriched gas supply tube is crushed by the body when the body is moved, or the headset is detached due to the tube being pulled.
また、就寝時における酸素富化ガス供給チューブの絡まりを解決する別の態様例として、特開２００４−３２１５８０号公報には、頭部取り付け用部材を備えた酸素投与手段が開示されている。この供給用具では、酸素富化ガス供給チューブは、頬の方向からではなく、頭部方向から両目の間を通すことで鼻孔まで酸素富化ガス供給チューブが導かれる。これにより、就寝時に使用者が身体を動かしたとしても酸素富化ガス供給チューブの捩れや巻き付きは生じない。また頭部を横に向けても、チューブが頬を圧迫する心配は無い。しかしながらこのシステムはチューブが使用者の視野を遮るため、昼間などの活動時の使用には適さない。 As another example of solving the entanglement of the oxygen-enriched gas supply tube at bedtime, Japanese Patent Application Laid-Open No. 2004-321580 discloses an oxygen administration means including a head mounting member. In this supply device, the oxygen-enriched gas supply tube is guided not from the cheek direction but between the eyes from the head direction to guide the oxygen-enriched gas supply tube to the nostril. Thereby, even if the user moves his / her body at bedtime, the oxygen-enriched gas supply tube is not twisted or wound. Even if the head is turned sideways, there is no worry that the tube will compress the cheek. However, this system is not suitable for use during activities such as daytime because the tube blocks the user's vision.
現在使用している鼻孔カニューラでは、固定するために酸素富化ガス供給チューブが頬や耳を強く圧迫し、使用者に不快感，汗群れ，潰瘍を生じさせる場合がある。特許文献１の方法では、就寝時にアーム部が頬を強く圧迫することが問題となる。また特許文献２の方法では、酸素富化ガス供給チューブが使用者の視野の邪魔になり供給用具の使用が夜間に限定される。
In presently used nostril cannula, the oxygen-enriched gas supply tube may strongly press the cheeks and ears for fixation, causing discomfort, sweating, and ulcers to the user. In the method of

Embodiment examples of the oxygen-enriched gas supply device of the present invention will be described below.
FIG. 1 shows a schematic diagram of a headset-type oxygen-enriched gas supply tool having an arm portion for holding an oxygen-enriched gas supply tube. In such a supply device, the arm (2) extends from the headset (1), which is a curved U-shaped support placed on the user's head, to the vicinity of the nose and mouth. A means for fixing the oxygen-enriched gas supply tube (4) connected to an oxygen gas supply source (3) such as a cylinder is provided to guide oxygen to the vicinity of the nostril. The arm (2) and the oxygen-enriched gas supply tube (4) are fixed by providing a connection nozzle at the end of the arm and connecting it to the tube, and oxygen enrichment via a hollow conduit provided in the arm. A method of supplying gas to the nostril, which is the other end, and a method of guiding the oxygen-enriched gas supply tube to the nostril along the arm by providing a tube fixing means with a U-shaped groove structure on the arm (2) can do.
アーム(2)は、ヘッドセット(1)の上を移動する可動支持体であるスライダ(5)に接続され、ヘッドセット(1)に沿ってアーム(2)を移動させることができる。アーム(2)は、使用者の耳付近に相当するヘッドセットの端(6)や頭頂部に相当するヘッドセットの中央部(7)に移動させることが出来、複数の場所、少なくとも前記2箇所で固定することができる。 The arm (2) is connected to a slider (5) that is a movable support that moves on the headset (1), and the arm (2) can be moved along the headset (1). The arm (2) can be moved to the end (6) of the headset corresponding to the vicinity of the user's ear and the center (7) of the headset corresponding to the top of the head, and can be moved to a plurality of locations, at least the two locations. It can be fixed with.
昼間使用時には、図２に示すように、アーム(8)をヘッドセット端(9)に固定すると、アーム(8)は使用者の視野に入らず、日常活動に支障が少ない状態で酸素富化ガスを供給することができる。また、夜間使用時には、図３に示すように、アーム(10)をヘッドセット中央部(11)に固定すると、頭部を動かしてもアーム(10)が使用者の頬を圧迫することがなく、かつ、酸素富化ガス供給用チューブが折れたり、捩れたりすることもなく酸素供給を実現することができる。 During daytime use, as shown in Fig. 2, when the arm (8) is fixed to the headset end (9), the arm (8) does not enter the user's field of view and is enriched with oxygen with little hindrance to daily activities. Gas can be supplied. In addition, when using at night, as shown in FIG. 3, when the arm (10) is fixed to the center of the headset (11), the arm (10) does not press the user's cheek even if the head is moved. In addition, oxygen supply can be realized without breaking or twisting the oxygen-enriched gas supply tube.
なお、頭部の大きさ、顔面形状の個体差は大きく、必要なヘッドセットの長さ、ヘッドセット端から鼻口付近までの距離は、装着者の頭部形状により異なるが、ヘッドセットやアームに長さの調節手段を持たせることで、個体差を調整し適切に装着することが可能となる。同様に、ヘッドセット側端から鼻・口付近への距離と、ヘッドセット中央部から鼻口付近への距離も若干異なるが、アーム部の長さの調整手段により、距離、角度の微調整が可能となり、適切に装着することが可能となる。一方、ヘッドセット側端から鼻・口付近へ導くアームの角度と、ヘッドセット中央部から鼻口付近へ導くアームの角度はほぼ同じであり、アーム自体の角度調整手段はあってもなくても良い。長さ調整手段としてはアームあるいはヘッドセットが可動支持体及びそれと勘合するスリーブから構成し、両者をスライドさせることで長さ調整を行うことができる。
アーム先端に酸素富化ガス供給用チューブに接続されるマスク等を設けることで、供給された酸素富化ガスは鼻孔付近に集中的に供給することが出来る。
The individual differences in head size and face shape are large, and the required length of the headset and the distance from the end of the headset to the vicinity of the nostril vary depending on the shape of the head of the wearer. By providing a length adjusting means, it is possible to adjust individual differences and to attach appropriately. Similarly, the distance from the side of the headset to the nose / mouth and the distance from the center of the headset to the vicinity of the nose are slightly different, but the adjustment of the length of the arm allows fine adjustment of the distance and angle. It becomes possible, and it becomes possible to attach appropriately. On the other hand, the angle of the arm leading from the headset side end to the vicinity of the nose and mouth is almost the same as the angle of the arm leading from the center of the headset to the vicinity of the nostril, with or without the angle adjustment means of the arm itself good. As the length adjusting means, an arm or a headset is composed of a movable support and a sleeve to be fitted with it, and the length can be adjusted by sliding both.
By providing a mask or the like connected to the oxygen-enriched gas supply tube at the end of the arm, the supplied oxygen-enriched gas can be concentratedly supplied near the nostril.
別の態様としては、図４に示すようにスライダ(12)には鼻口付近まで伸びるアームではなく、酸素富化ガス供給用チューブ(13)を直接接続する固定具(14)を設けてもよい。この固定方法を用いる際には、固定具(14)から鼻・口付近へ伸びるチューブ(13)にはチューブ内壁に針金などを組み込むことで、チューブ強度を確保しつつ、長さ角度など供給位置の調節が容易となる。 As another embodiment, as shown in FIG. 4, the slider (12) may be provided with a fixture (14) for directly connecting the oxygen-enriched gas supply tube (13) instead of the arm extending to the vicinity of the nostril. Good. When using this fixing method, the tube (13) extending from the fixture (14) to the vicinity of the nose and mouth is incorporated with a wire etc. on the inner wall of the tube, ensuring the strength of the tube while maintaining the supply position such as the length angle. It becomes easy to adjust.
また、スライダを用いてアーム(15)がヘッドセット上を移動する構造ではなく、図５に示すように、ヘッドセット端、及びヘッドセット中央部に、ネジ止め等の取り外し可能な接続機構(16),(17)を設けることにより、かかる課題を解決できる。また図６に示すように、ヘッドセット端(18)及びヘッドセット中央部(19)に酸素富化ガス供給用チューブの固定具、あるいは簡便には固定可能な穴を設けてもよい。 Further, the arm (15) is not structured to move on the headset using a slider, but as shown in FIG. 5, a removable connection mechanism (16) such as screwing is provided at the headset end and the center of the headset. ) And (17) can solve this problem. As shown in FIG. 6, a fixture for an oxygen-enriched gas supply tube or a hole that can be simply fixed may be provided at the headset end (18) and the center of the headset (19).
なお、夜間使用時に、頭部に載せるヘッドセットのみでは不安定で、頭部を動かした際に外れる危険性があるため、図７に示すように、頭部上部から頭部後付近へ伸びるバンド(20)や頭部側面から後頭部付近を横切るバンド(21)などの補強具を取り付け、安全性を高めることも可能である。 Note that the band that extends from the upper part of the head to the vicinity of the back of the head as shown in FIG. It is also possible to enhance safety by attaching a reinforcing tool such as (20) or a band (21) that crosses the back of the head from the side of the head.
本発明の酸素富化ガス供給用具は、酸素富化ガス、酸素ガス以外にも、噴霧薬、水蒸気、匂い物質などを投与する際にも適用可能である。 The oxygen-enriched gas supply device of the present invention can be applied to administration of sprays, water vapor, odorous substances, etc. in addition to oxygen-enriched gas and oxygen gas.
