Abstract
【課題】吸気側の高濃度酸素と呼気側の二酸化炭素の混合をなくし、呼吸時に供給される高濃度の酸素を有効的に吸気できるようにした酸素濃縮器用酸素マスクを提供する。
【解決手段】マスク本体１の内側に、鼻を覆う部位と口を覆う部位の間に仕切り板２を設けて吸気室３と呼気室４に分け、吸気室に接続コネクタ６を介して供給される高濃度酸素は鼻からの吸気を自在とするとともに、呼気室に排出される呼気を呼気排出口５からマスク本体の外部に排出自在にした。
【選択図】図５To provide an oxygen mask for an oxygen concentrator in which mixing of high-concentration oxygen on the inhalation side and carbon dioxide on the expiratory side is eliminated, and high-concentration oxygen supplied during breathing can be effectively inhaled.
A partition plate 2 is provided inside a mask body 1 between a portion covering a nose and a portion covering a mouth to divide into an intake chamber 3 and an expiratory chamber 4 and supplied to the intake chamber via a connector 6. The high concentration oxygen allows inhalation through the nose and exhalation into the expiration chamber through the exhalation outlet 5 to the outside of the mask body.

Description
酸素濃縮器（酸素ボンベ等を含む。）より、高濃度の酸素を酸素吸入者に供給するための酸素マスクに関する。 The present invention relates to an oxygen mask for supplying high concentration oxygen to an oxygen inhaler from an oxygen concentrator (including an oxygen cylinder and the like).
従来この種の酸素マスクは図１、図２に示すように、酸素吸入(吸気)と、体内からの二酸化炭素の排出(呼気)を、吸気側と呼気側が一体のマスク内に行うため、マスク内で酸素濃縮器から供給された高濃度酸素と呼気が酸素マスク内に貯留・混合し、そのためマスク内では酸素濃度が低下することになり、濃度の低下した酸素を吸気していた。
また、呼気排出口が鼻の高さの位置にあるため、高濃度酸素は、鼻から吸気される前に、呼気排出口から排出されて無駄となる恐れがあった。
Conventionally, as shown in FIGS. 1 and 2, since this type of oxygen mask performs oxygen inhalation (inhalation) and discharge of carbon dioxide from the body (expiration) in the integrated mask on the inspiration side and exhalation side, The high-concentration oxygen and the exhaled air supplied from the oxygen concentrator in the inside are stored and mixed in the oxygen mask, so that the oxygen concentration is reduced in the mask, and the oxygen whose concentration has been reduced is inhaled.
In addition, since the exhalation outlet is located at the height of the nose, there is a possibility that the high concentration oxygen is discharged from the exhalation outlet before being inhaled from the nose and is wasted.
そこで本考案では、マスク本体の鼻を覆う部分と口を覆う部分の間に、仕切り板を入れて、吸気時は鼻から吸気し、口からの呼気を排出自在として、マスク内に排出された呼気は、マスクの口を覆う部分に設けた呼気排出口より外部に排出されるようにし、吸気側の高濃度酸素と呼気側の二酸化炭素の混合をなくし、呼吸時に酸素濃縮器から供給される高濃度の酸素を有効的に吸気することができるようにしようとするものである。 Therefore, in the present invention, a partition plate is inserted between the part of the mask body covering the nose and the part covering the mouth, and when inhaling, the air is inhaled from the nose and the exhaled air is freely discharged into the mask. The exhaled air is exhausted to the outside through an exhalation exhaust port provided in a portion covering the mouth of the mask, eliminating mixing of high-concentration oxygen on the inspiration side and carbon dioxide on the exhalation side, and supplied from the oxygen concentrator during breathing It is intended to make it possible to effectively inhale a high concentration of oxygen.
本考案は、マスク本体の内側に、鼻を覆う部位と口を覆う部位の間に仕切り板を設けて吸気室と呼気室に分け、吸気室に供給される高濃度酸素は鼻からの吸気を自在とするとともに、呼気室に排出される呼気をマスク本体の外部に排出自在した酸素濃縮器用酸素マスクである。 In the present invention, a partition plate is provided on the inner side of the mask body between the part covering the nose and the part covering the mouth to divide into an inspiratory chamber and an expiratory chamber, and the high-concentration oxygen supplied to the inspiratory chamber absorbs inhalation from the nose. An oxygen mask for an oxygen concentrator in which the exhaled air discharged into the exhalation chamber can be freely discharged to the outside of the mask body.
こうすることによりマスク本体の呼気室側に排出された呼気は、仕切り板があるため、吸気室側に侵入したり貯留することなく（或いは可及的に少なくなる。）、呼気室側の側部に設けたに設けた呼気排出口より外部に排出され、吸気室側の高濃度酸素と呼気室側の二酸化炭素が混合することはなくなり、呼吸時は酸素濃縮器から供給される高濃度の酸素を吸気し続けることができ、酸素の吸気に必要な高濃度酸素の供給量も従来より少量ですむ。 In this way, the exhaled air exhausted to the exhalation chamber side of the mask main body has a partition plate, so that it does not enter or accumulate (or is reduced as much as possible) on the inhalation chamber side. The high-concentration oxygen on the inspiratory chamber side and the carbon dioxide on the expiratory chamber side are not mixed, and the high-concentration supplied from the oxygen concentrator during breathing is eliminated. Oxygen can be continuously inhaled, and the supply amount of high-concentration oxygen necessary for inhaling oxygen is smaller than before.
マスク本体１の内側に、鼻を覆う部位と口を覆う部位の間に仕切り板２を設けて吸気室３と呼気室４に分け、吸気室３に供給される高濃度酸素は鼻からの吸気を自在とするとともに、呼気室４に排出される呼気を該呼気室４の側部に設けた呼気排出口５より外部に排出自在したしたものである。 A partition plate 2 is provided inside the mask main body 1 between a portion covering the nose and a portion covering the mouth, and is divided into an inspiratory chamber 3 and an expiratory chamber 4, and high-concentration oxygen supplied to the inspiratory chamber 3 is inhaled from the nose. The exhaled air discharged into the exhalation chamber 4 can be discharged outside through an exhalation discharge port 5 provided on the side of the exhalation chamber 4.
呼気排出口５は図６のように呼気室４の下方を解放して設け、下部外方に呼気を排出するようにしてもよい。その他呼気の排出手段としては汎用の手段でもよく、また弁などを併用してもよい。 The expiratory outlet 5 may be provided so as to open below the expiratory chamber 4 as shown in FIG. Other expiratory discharge means may be general-purpose means, or a valve may be used in combination.
図中６は接続コネクタで図示しない酸素濃縮器や酸素ボンベからの酸素チューブを接続するものである。 In the figure, reference numeral 6 denotes a connection connector for connecting an oxygen concentrator and an oxygen tube from an oxygen cylinder (not shown).
呼気排出口５は呼気室４の下方を解放して下部外方に呼気を排出するようにしてもよい。その他呼気の排出手段としては汎用の手段でもよく、また弁などを併用してもよい。 The exhalation discharge port 5 may release the lower part of the exhalation chamber 4 to discharge exhalation to the lower outside. Other expiratory discharge means may be general-purpose means, or a valve may be used in combination.
