即ち、本発明の携帯用人工呼吸器のバクテリアフィルター付き逆止弁1は、上側ケーシング2と下側ケーシング3と救助者側開口部フィルター4と排気穴フィルター5と通気用逆止弁6とから成るものである。 That is, from the portable ventilator bacterial filter with check valve 1 of the present invention, the upper casing 2 and lower casing 3 and the rescuer side opening filter 4 and the exhaust hole filter 5 and the ventilation check valve 6 which it is those made.

そして、上側ケーシング2は一端に後述する外気用逆止弁6と接続する円筒状に突出させた救助者側開口部2aを開口させ、他端にはフランジ状に膨出させた上側ケーシング段部2bと、更に、上側ケーシング段部2bの外周には上側ケーシング接続部2cを延設しており、該上側ケーシング接続部2cは後述する下側ケーシング接続部3dと螺合させるためのネジを螺設しているものである。 Then, the upper casing 2 is opened the rescuer side opening 2a which projects into a cylindrical shape to be connected to the outside air check valve 6 which will be described later on one end, the upper housing shoulder portion to the other end is bulged like a flange threadably 2b, further, the outer periphery of the upper housing shoulder portion 2b has extended the upper casing connection section 2c, the upper-side casing connecting portion 2c of the screw for screwing the lower casing connecting portion 3d, which will be described later it is those that are set.

次に、下側ケーシング3は一端に後述する被救助者用マスク9と接続する円筒状に突出させた被救助者側開口部3aを開口させ、他端にはフランジ状に下側ケーシング段部3bを膨出させ、下側ケーシング段部3bには排気穴3cを開口させており、更に、下側ケーシング段部3bの外周には下側ケーシング接続部3dを延設して前記上側ケーシング接続部2cと螺合させるネジを螺設しているものである。 Next, the lower casing 3 is opened to be rescuer side opening 3a which projects into a cylindrical shape to be connected to the rescuer mask 9 to be described later on one end, the lower housing shoulder portion in a flange shape at the other end 3b is bulged and the lower casing stepped portion 3b and is opened to exhaust holes 3c, further the upper casing connected to extend the lower casing connecting portion 3d on the outer periphery of the lower housing shoulder portion 3b the parts 2c and threaded screwing those that are screwed.

次いで、救助者側開口部バクテリアフィルター4は救助者側開口部2aを遮蔽するように上側ケーシング段部2bに更に段部を設けて取り付けており、下方からは係止部材で係止させており、救助者の呼気を濾過するものである。 Then the rescuer side opening bacterial filter 4 is mounted provided with a further stepped portion on the upper housing shoulder portion 2b to shield the rescuer side opening 2a, and is engaged with the locking member from below , it is intended to filter the breath of the rescuer.

更には、排気穴バクテリアフィルター5はドーナツ状に形成されており、排気穴3cを遮蔽するよう下側ケーシング段部3bに載置されるもので、被救助者の呼気を濾過するものである。 Furthermore, the exhaust hole bacterial filter 5 is formed in a donut shape, intended to be placed on the lower casing stepped portion 3b so as to shield the exhaust hole 3c, it is intended to filter exhaled of the rescuer.

更に、通気用逆止弁6は実施例では中央に谷状に窪むベローズ6bを形成し、該ベローズ6bの先端は線状に切込開口部6cを形成しており、ベローズ6bの基部はフランジ状に膨出させた下側ケーシング段部3cと接触又は離間を自在とする、つまり、下側ケーシング段部3bに開口させている排気穴3cを開閉させるフランジ状の通気用逆止弁鍔部6dを形成しており、更に、通気用逆止弁鍔部6dの外周には下側ケーシング接続部3dに沿って短円筒状に環状部6eを立ち上げ、更には、上側ケーシング接続部2cと下側ケーシング接続部3dとの間に挟持される外周縁部6aを一体に形成した軟質合成樹脂やゴム等で形成された膜状のものである。 Further, the vent check valve 6 to form a bellows 6b recessed in trough in the middle in the embodiment, the tip of the bellows 6b forms a notch opening 6c linearly, the base of the bellows 6b is and freely contact with or spaced from the lower casing stepped portion 3c which is bulged in a flange shape, that is, the check valve flange for flange-shaped vent opening and closing the exhaust holes 3c which is opened to the lower housing shoulder portion 3b It forms a part 6d, further up the annular portion 6e along the lower casing connecting portion 3d on the outer periphery of the vent check Bentsuba portion 6d into short cylindrical, furthermore, upper casing connecting portion 2c those of the lower casing connection section 3d and the like membrane that the outer peripheral edge portion 6a sandwiched formed of soft synthetic resin or rubber or the like formed integrally between.

そして、通気用逆止弁6は上側ケーシング2と下側ケーシング3とを仕切るように配設され、上側ケーシング2が加圧、つまり、救助者側が呼気を行うと救助者側開口部2aと被救助者側開口部3aが連通状態となり、救助者側から被救助者側に空気を送られるものであり、この状態では、通気用逆止弁6の通気用逆止弁鍔部6dには上から圧力が加わり排気穴3cは閉鎖されているものである。 And, the vent check valve 6 is disposed so as to separate the upper casing 2 and lower casing 3, the upper casing 2 is pressurized, that is, the rescuer side performs exhalation and rescuers side opening 2a the rescuer side opening 3a is a communicating state, and from the rescuer's side intended to be directed air to the rescuer's side, in this state, above the vent check Bentsuba portion 6d of the ventilation check valve 6 pressure is applied from the exhaust hole 3c is what is closed.

次いで、上側ケーシング2が負圧になると、つまり、救助者が吸気を行うと通気用逆止弁6により救助者側開口部2aと被救助者側開口部3aが閉鎖状態となると共に、救助者側開口部2aに外気用逆止弁7を接続していることにより、外気が外気用逆止弁7から流入し、救助者は新鮮な外気を吸引するものである。 Then, when the upper casing 2 is a negative pressure, that is, with rescuer side opening 2a and the rescuer side opening 3a is closed by the ventilation check valve 6 when the rescuer performing intake, rescuer by connecting the ambient air check valve 7 to the side opening 2a, the outside air flows from the ambient air check valve 7, the rescuer is to sucking fresh outdoor air.

次に、下側ケーシング3が加圧になる、つまり、被救助者が呼気を行うと救助者側開口部2aと被救助者側開口部3aが閉鎖状態となると共に、通気用逆止弁6が下方から上方に持ち上げられ被救助者側の呼気は排気穴3cから排気され雰囲気中の外気に放出されるものである。 Next, the lower casing 3 becomes pressurized, that is, with rescuer side opening 2a and the rescuer side opening 3a and the rescuer performs exhalation is closed, the check valves for ventilation 6 There the rescuer side exhalation lifted from below to above is intended to be released into the ambient air in the atmosphere is exhausted from the exhaust hole 3c.

更に、外気用逆止弁7はバクテリアフィルター付き逆止弁1の救助者側開口部2aに接続され外気を取り入れるものであり、つまり、救助者が呼気を行う時には閉鎖されており、救助者が吸気を行う時には開口されるもので、救助者は被救助者の呼気を吸引することはなく新鮮な外気を吸引できるものである。 Moreover, ambient air check valve 7 is intended to introduce the outside air is connected to the rescuer's side opening 2a of the bacterial filter with check valve 1, that is, rescuers are closed when performing the breath, rescuer when performing an intake intended to be opened, the rescuer is one capable of sucking fresh outdoor air rather than aspirating the expiration of the rescuer.

更には、蛇腹管8は可撓性部材の合成樹脂等で伸縮自在に形成され、外気用逆止弁7に接続させているもので、各段の折曲部位は短縮されたときに皿状に積層された状態でコンパクトに保持でき、湾曲及び伸縮が自在なものであり、延伸状態で使用することも、短縮状態で使用することも可能であり、先端には救助者が口に銜えるマウスピース8aを取着しているものである。 Furthermore, dish-shaped when the bellows tube 8 is freely formed elastic synthetic resin or the like of the flexible member, one that has to be connected to the outside air check valve 7, the bending portion of each stage was shortened can be held compactly in a state of being stacked in are those freely curved and stretchable, also be used in oriented state, it is also possible to use in a shortened state, the tip Carrying in mouth rescuer mouth those that attach the mouthpiece 8a.

上記の構成により、救助者が吸気を行うと、外気が外気用逆止弁7より蛇腹管8を経由して吸込まれるので、吸気の終わりには、蛇腹管8の中は外気(酸素21%、炭酸ガス0%)で満たされるものであり、次いで、救助者が被救助者に呼気を吹き込むと、蛇腹管8に満たされている酸素濃度が高く炭酸ガス濃度の低いガスが吹き込まれるものである。 With the above configuration, the rescuer performing intake, since outside air is sucked through the bellows tube 8 from the outside air check valve 7, at the end of inspiration, the outside air in the bellows tube 8 (oxygen 21 %, which is filled with carbon dioxide 0%), then the rescuer blowing breath into the rescuer, which low oxygen concentration which is filled in the bellows tube 8 has a high carbon dioxide concentration gas is blown it is.

そして、バクテリアフィルター付き逆止弁1の被救助者側開口部3aは被救助者用マウス9の上方の斜め位置に接続させたものであり、救助者の姿勢が楽になり他の心臓マッサージ等の施術が同時に行うことができ、更には、目線でも的確に被救助者の顔を捕らえること容易とするものである。 Then, the rescuer side opening 3a of the bacterial filter with non-return valve 1 is one obtained by connecting the upper oblique position of the rescuer's mouse 9, rescuer postures such as other cardiac massage easier treatment is can be done at the same time, further, it is an easy to capture the face precisely the rescuer in eyes.
