Abstract

The present invention relates to a manual artificial respiration device that is capable of controlling the flow of exhaled air and the oxygen concentration of inhaled air. The present invention includes an air bag filled with oxygen gas supplied from an oxygen container, and an oxygen supply pipe for supplying the oxygen in the air bag to the respiratory tract of a patient by the compression of the air bag. One side of the oxygen supply pipe includes an oral connection pipe which is configured to be in close contact with the respiratory tract of the patient, and the other side, which has branched ducts, is branched into a first branch port leading to an exhalation pipe equipped with an exhalation valve, and a second branch port leading to an air bag connection pipe wherein the control valve for the air inhalation and exhalation duct is disposed at the position where the first branch port and the second branch port are branched. During the inhalation of air, the control valve for the air inhalation and exhalation duct opens the second branch port and closes the first branch port using pressure from the oxygen gas caused by the compression of the air bag. The lower valve of the air bag, which is connected to an oxygen container connection pipe, is provided at one end portion inside the air bag. During the inhalation of air, the lower valve of the air bag is closed by the pressure of the oxygen gas caused by the compression of the air bag so that the oxygen gas inside the air bag is discharged toward the oxygen supply pipe.

Various types of ventilators are being developed that can lead quickly.
도 1은 종래 병원의 응급실이나 구급차에 탑재된 일반적인 인공 호흡장치의 구성을 나타내는 개략도로서, 도면에 도시된 바와 같이, 산소 용기(1)로부터 배출되는 산소 가스가 출력구를 통해 배출되도록 하는 레귤레이터(2), 레귤레이터(2)와 접속되는 산소 공급관(3), 산소 공급관 상에 설치되어 산소 용기(1)로부터 공급되는 산소량을 단속하는 밸브(4), 산소 공급관(3)을 지나는 산소의 압력을 감지하기 위한 압력센서(5) 및 압력센서(5)에서 감지된 정보에 따라 밸브(4)의 온/오프 동작을 제어하는 제어부(6)를 구비한다.Figure 1 is a schematic diagram showing the configuration of a general ventilator mounted in an emergency room or an ambulance of a conventional hospital, as shown in the regulator, the oxygen gas discharged from the oxygen container 1 through the outlet ( 2), the oxygen supply pipe 3 connected to the regulator 2, the valve 4 provided on the oxygen supply pipe to control the amount of oxygen supplied from the oxygen container 1, and the pressure of oxygen passing through the oxygen supply pipe 3 And a control unit 6 for controlling the on / off operation of the valve 4 according to the pressure sensor 5 for sensing and the information sensed by the pressure sensor 5.
상기와 같은 일반적인 인공 호흡장치는 산소 공급관(3)에 설치된 압력 센서(5)로부터 제공된 정보에 따라 밸브(4)가 제어되어 상기 산소 용기(1)로부터 배출되어 출력구로 제공되는 산소량이 조절될 수 있도록 구성되기 때문에 혼합 가스 탱크의 압력을 일정하게 유지할 수 없어 무호흡 환자의 자발 호흡을 빠르게 유도할 수 없는 문제점이 있었다.In the general ventilator as described above, the valve 4 is controlled according to the information provided from the pressure sensor 5 installed in the oxygen supply pipe 3 so that the amount of oxygen discharged from the oxygen container 1 and provided to the output port can be adjusted. Since the pressure of the mixed gas tank cannot be kept constant, there is a problem in that spontaneous breathing of apnea patients cannot be induced quickly.
한편, 기존의 수동식 인공 호흡장치는 공기저장 주머니의 용량이 1500~1600 ml로서 그 크기가 상당히 크기 때문에 산소 사용량이 많아 비효율적일 뿐만 아니라 때때로 응급상황에서 산소가 부족하여 곤란한 경우도 종종 발생하게 되며, 공기저장 주머니의 크기가 커서 응급상황에서 반드시 두 손을 사용해야만 하는 사용상의 단점이 있고, 복원력에도 문제가 발생하게 되는 등의 여러 가지 단점이 있었다. 또한 이러한 수동식 인공 호흡장치를 손으로 조작하게 될 때 시술자의 경험과 느낌에 의존해서 용량을 조절하여야만 하므로 환자의 폐에 무리를 줄 수 있는 문제점이 있다.On the other hand, the conventional manual ventilator is 1500 ~ 1600 ml of air storage bag capacity is quite large because of its large amount of oxygen consumption is not only inefficient, but also sometimes in the emergency situation, it is often difficult to lack oxygen, The large size of the air storage bag has the disadvantages of using two hands must be used in an emergency, there are a number of disadvantages, such as problems in resilience. In addition, when the manual ventilation device is operated by hand, it is necessary to adjust the dose depending on the experience and feeling of the operator, so there is a problem that can give a burden to the lungs of the patient.
또한 이러한 기존의 수동식 인공 호흡장치는 흡기 밸브에 리저버백을 부착해서 사용하더라도 대기 공기가 유입될 경우 대기 공기와 혼합되어 원하는 수준의 산소 농도를 유지할 수 없는 구조로 되어 있으며, 특히 구급차 등에서 수동식 인공 호흡장치를 작동시키기 위해서는 1~2명의 시술자가 반드시 동승하여 시술하여야만 하는 사용상의 단점이 있다.In addition, even if the existing manual ventilator is attached to the intake valve by using a reservoir bag, when the atmospheric air flows in, it is mixed with the atmospheric air to maintain a desired level of oxygen concentration, especially in the ambulance, etc. In order to operate the device there is a disadvantage in use that must be carried out by one to two operators.
본 발명이 해결하고자 하는 기술적 과제는, 배기 공기의 유량 조절이 가능하고 흡기 공기의 산소 농도를 조절할 수 있으면서도 자동으로 작동 가능하도록 한 간단한 구조의 수동식 인공호흡장치를 제공하고자 하는 것이다.The technical problem to be solved by the present invention is to provide a manual ventilation device of a simple structure that can be adjusted automatically while the flow rate of the exhaust air can be adjusted and the oxygen concentration of the intake air.

도 2는 본 발명의 일 실시 형태에 의한 인공 호흡장치의 구성을 간략하게 예시한 구성도로서, 도면에 도시된 바와 같이 본 발명의 일 실시 형태에 따른 인공 호흡장치는, 공기 주머니(12), 개방식 산소 공급관(14), 흡배기 관로조절밸브(15), 압력 조절밸브(16)로 구성된다.2 is a configuration diagram briefly illustrating a configuration of a respirator according to an embodiment of the present invention. As shown in the drawing, a respirator according to an embodiment of the present invention includes an air bag 12; Open oxygen supply pipe 14, the intake and exhaust pipe line control valve 15, the pressure control valve (16).
공기 주머니(12)는 응급 상황에서 시술자가 한 손으로 압축 가능한 크기 및 부피의 공기 주머니로서, 1~1.2리터의 흡기 용량을 저장할 수 있는 내부 공간을 구비하는 공기 주머니로 이루어지며, 그 일측 단부에는 공기주머니 하단밸브(11)가 구비되어 산소 용기로부터 배출되어 직접 제공되거나 또는 레귤레이터를 통해 제공되는 산소(O2) 가스를 산소용기 연결관(37)를 통해 공급받고, 다른측 단부에는 개방식 산소 공급관(14)으로 산소 배출을 위한 관로인 공기주머니 연결관(35)이 연결되어 있어, 공기 주머니에 저장된 흡기 공기를 관로로 공급할 수 있도록 구성된다. 공기주머니 하단 밸브(11)는 산소용기로부터 제공되는 산소 가스가 들어올때만 공기 주머니(12) 쪽으로만 개방되는 단방향성 개방 밸브이다. 따라서, 공기주머니 하단 밸브(11)는 흡기 순간(시술자가 공기주머니를 압축한 때)에는 폐쇄되어 흡기시 공기 주머니의 공기가 개방식 산소 공급관(14) 쪽으로만 배출되되, 흡기시의 공기가 흡배기 관로조절밸브(15)를 밀어 올리도록 되어, 개방식 산소 공급관(14)을 통해 환자에게 제공되며, 흡기 직후에는 즉시 흡배기 관로조절밸브(15)도 아래로 내려오며, 동시에 공기주머니 하단 밸브(11)도 개방되어 산소 용기로부터 공기 주머니(12) 쪽으로 산소 가스가 공급될 수 있게 하며, 공기 주머니(12)에 일정량의 공기가 채워지면 자동으로 폐쇄된다.The air bag 12 is an air bag of a size and volume that the operator can compress with one hand in an emergency, and is made of an air bag having an internal space capable of storing an intake capacity of 1 to 1.2 liters. An air bag bottom valve 11 is provided to supply oxygen (O 2 ) gas, which is directly discharged from an oxygen container or provided through a regulator, through an oxygen container connecting pipe 37 and an open oxygen supply pipe at the other end. 14 is connected to the air bag connecting pipe 35 is a pipe for oxygen discharge, it is configured to supply the intake air stored in the air bag to the pipe. The air bag bottom valve 11 is a unidirectional opening valve that opens only toward the air bag 12 only when oxygen gas provided from the oxygen container enters. Therefore, the air bag bottom valve 11 is closed at the moment of intake (when the operator compresses the air bag) so that the air in the air bag is discharged only toward the open oxygen supply pipe 14 at the time of intake, and the air at the time of intake passes to the intake and exhaust pipe line. The control valve 15 is pushed up, which is provided to the patient through the open oxygen supply pipe 14, and immediately after the intake, the intake and exhaust pipe control valve 15 is also lowered, and at the same time, the air bag lower valve 11 is also provided. It is opened to allow oxygen gas to be supplied from the oxygen container toward the air bag 12 and is automatically closed when the air bag 12 is filled with a certain amount of air.
공기주머니 하단 밸브(11)는 산소용기 연결관(37)과 공기 주머니(12)의 사이에 위치되며, 공기 주머니(12)내에서 산소용기 연결관(37)의 입구의 일측에 공기주머니 하단 밸브(11)의 힌지부가 장착되어 있어, 산소용기 연결관(37)을 통해 들어오는 산소가스의 압력에 의해 열려지게되며, 그외의 경우에는 닫혀있다. The air bag bottom valve 11 is positioned between the oxygen container connector 37 and the air bag 12, and the air bag bottom valve is located at one side of the inlet of the oxygen container connector 37 in the air bag 12. The hinge part of (11) is mounted, and is opened by the pressure of the oxygen gas which enters through the oxygen container connecting pipe 37, and is closed in other cases.
여기서, 산소용기 연결관(37)은 산소 용기로부터 배출되어 직접 제공되거나 또는 레귤레이터를 통해 제공되는 산소(O2) 가스를, 공기주머니 하단 밸브(11)를 통해, 공기 주머니(12)에 넣기 위한 관이다.Here, the oxygen container connecting pipe 37 is discharged from the oxygen container is provided directly or through the regulator for the oxygen (O 2 ) gas, through the air bag bottom valve 11, for putting the air bag 12 It is a tube.
개방식 산소 공급관(14)은, 유체가 흐를 수 있는 하나의 관로가 내부에 형성되며, 'ㄱ'자형태로 이루어지며, 관로의 일측 단부는 환자의 기도에 밀착될 수 있도록 구성된 구강연결 관(39)을 구비하고, 다른측 단부는 내부 관로가 분기되어, 일측은 배기 밸브(13)가 장착된 배출관(30)으로 이어지며, 다른 일측은 공기 주머니(12)와 연결된 공기주머니 연결관(35)로 이어지는, 두 분기구가 형성되며, 그 분기 지점에는 흡배기 관로조절밸브(15)가 설치되어 있다. 두 분기구는 흡배기 관로조절밸브(15)에 의해 각 분기구가 상대적으로 개폐되도록 구성된다. 즉 흡배기 관로조절밸브(15)는 흡기 때는 공기주머니 연결관(35)은 개방하면서 배출관(30)은 폐쇄하고, 반대로 호기(배기) 때는 배출관(30)을 개방하면서 공기주머니 연결관(35)을 폐쇄하도록 구성된다. 또한 배기 밸브(13)는 흡기 때는 폐쇄되고 호기(배기) 때는 개방되도록 구성되므로 이러한 개방식 산소 공급관(14)의 내부 관로에는 흡기 때는 공기 주머니(12)의 흡기 공기가 관로를 통해 환자 쪽으로 공급될 수 있게 되며, 호기 때는 환자로부터의 호기 가스가 배기 밸브(13)를 통해 외부로 방출될 수 있게 된다.The open oxygen supply pipe 14 has a single flow passage through which a fluid can flow, and is formed in a '-' shape, and one end of the flow passage is configured to be in close contact with the patient's airway. ), The other end of which is branched into an inner conduit, one side of which leads to an exhaust pipe (30) equipped with an exhaust valve (13), and the other side of the air bag connector (35) connected to the air bag (12). Two branching ports are formed, leading to the intake and exhaust pipe line control valve 15. The two branches are configured such that each branch is opened and closed relatively by the intake and exhaust pipe line control valve 15. That is, the intake and exhaust pipe line control valve 15 opens the air bag connecting pipe 35 while intake, while closing the discharge pipe 30, and on the contrary, during the exhalation (exhaust), the air bag connecting pipe 35 is opened while opening the discharge pipe 30. Configured to close. In addition, since the exhaust valve 13 is configured to be closed at intake and open at exhalation (exhaust), the inlet air of the open oxygen supply pipe 14 may be supplied to the patient through the conduit to the intake air of the air bag 12. In the exhalation, the exhalation gas from the patient can be released to the outside through the exhaust valve (13).
흡배기 관로조절밸브(15)는 개방식 산소 공급관(14)의 두 분기구 중간 지점에 설치되어 흡기와 배기 동작에 의해 자동으로 구동되어 흡기시와 배기시 산소 공급관(14) 내부에서 분기구에 의해 형성되는 유체의 관로를 선택적으로 개방하거나 폐쇄한다. 흡배기 관로조절밸브(15)는 일측에 힌지부와 연결되어, 위아래로 여닫이가 가능하도록 이루진다. 즉, 흡배기 관로조절밸브(15)는 배출관(30)의 입구의 좌우 일측중에, 공기 주머니(12)까지의 거리가 가까운 측에 힌지부가 장착된다. The intake / exhaust pipe control valve 15 is installed at an intermediate point between the two branch openings of the open oxygen supply pipe 14 and is automatically driven by the intake and exhaust operations, and is formed by the branch inside the oxygen supply pipe 14 during intake and exhaust. Selectively open or close the conduit of fluid to be made. Intake and exhaust pipe control valve 15 is connected to the hinge portion on one side, it is made to open and close up and down. That is, the intake and exhaust pipe line control valve 15 is mounted on the side of the left and right sides of the inlet of the discharge pipe 30, the side closer to the air bag 12, the hinge portion.
흡배기 관로조절밸브(15)는, 시술자가 공기 주머니(12)에 압력을 가하는 흡기시에는, 공기 주머니(12)로부터 들어오는 공기(즉, 산소가스)의 압력에 의해 흡배기 관로조절밸브(15)를 위로 들어 올려서, 배출관(30)를 차단(결과적으로 배기밸브(13)을 차단)하며, 공기주머니 연결관(35)을 개방하게 되어, 환자에게 공기(즉, 산소가스)를 공급한다. 반면, 흡배기 관로조절밸브(15)는, 공기 주머니(12)로부터 들어오는 공기(즉, 산소가스)의 압력이 가해지지 않는 상태에서는, 흡배기 관로조절밸브(15)는 아래로 내려와 공기주머니 연결관(35)을 차단하고, 배출관(30)을 개방(결과적으로 배기밸브(13)도 개방)하여, 환자가 내뿜는 가스(즉 이산화탄소)가 외부로 배출되게 한다. 즉, 흡배기 관로조절밸브(15)는, 공기 주머니(12)로 연결되는 분기구를 개방하면서 배기 밸브(13)로 연결된 분기구를 폐쇄하고, 반대로 배기시 배기 밸브(13)로 연결되는 분기구는 개방하면서 공기 주머니(12)로 연결된 분기구는 폐쇄하는 양방향성 밸브로 구성된다.The intake / exhaust pipe control valve 15 controls the intake / exhaust pipe control valve 15 by the pressure of air (that is, oxygen gas) coming from the air bag 12 when the operator applies pressure to the air bag 12. By lifting up, the exhaust pipe 30 is blocked (as a result, the exhaust valve 13 is blocked), and the air bag connecting pipe 35 is opened to supply air (ie, oxygen gas) to the patient. On the other hand, the intake and exhaust pipe control valve 15, while the pressure of the air (that is, oxygen gas) coming from the air bag 12 is not applied, the intake and exhaust pipe control valve 15 is lowered to the air bag connecting pipe ( 35) and the discharge pipe 30 is opened (as a result, the exhaust valve 13 is also opened), so that the gas exhaled by the patient (ie carbon dioxide) is discharged to the outside. That is, the intake and exhaust pipe line control valve 15 closes the branch connected to the exhaust valve 13 while opening the branch connected to the air bag 12, and conversely, the branch connected to the exhaust valve 13 when exhausting. The bifurcation valve is connected to the air pocket 12 while opening, and is composed of a bidirectional valve.
압력 조절밸브(16)는 개방식 산소 공급관(14) 상에 설치되어 산소 용기로부터 공급되는 산소의 압력을 조절하여 관로 내의 산소 압력을 조절한다. 압력 조절밸브(16)는, 평상시는 닫혀 있다가, 개방식 산소 공급관(14) 내의 압력이 높으면 자동 개방되도록 이루어질 수 있다. The pressure regulating valve 16 is installed on the open oxygen supply pipe 14 to regulate the pressure of oxygen supplied from the oxygen container to regulate the oxygen pressure in the conduit. The pressure regulating valve 16 may be normally closed but automatically opened when the pressure in the open oxygen supply pipe 14 is high.
배기 밸브(13)는 배출관(30)의 단부에 장착되어, 배출관(30)에 공기(즉, 환자가 배출한 이산화탄소)가 들어오면, 배기 밸브(13)를 밀어올려 외부로 배출하게 한다.The exhaust valve 13 is mounted at the end of the discharge pipe 30, when the air (that is, carbon dioxide discharged by the patient) enters the discharge pipe 30, the exhaust valve 13 is pushed up to discharge to the outside.
이와 같이 구성된 본 발명의 일 실시 형태에 따른 인공 호흡장치의 사용 방법을 살펴보면 다음과 같다.Looking at the use of the respirator according to an embodiment of the present invention configured as described above are as follows.
먼저 시술자에 의해 공기 주머니(12)가 압축되어 흡기 동작이 있게 되면 개방식 산소 공급관(14)의 분기 지점에 설치된 흡배기 관로조절밸브(15)는 흡기 동작에 의해 구동되어 공기주머니 연결관(35)(즉, 공기 주머니(12) 쪽으로 연결된 분기구)를 개방하면서, 배출관(30)(즉, 배기 밸브(13) 쪽으로 연결되는 분기구)를 폐쇄하게 되고, 따라서 배기 밸브(13)로 이어지는 호기 관로는 차단되고 공기 주머니(12)로 이어지는 흡기 관로는 개방될 수 있게 된다. 이러한 동작이 이루어지고 나면 공기 주머니(12)에 설치된 공기주머니 하단 밸브(11) 또한 즉시 공기 주머니 쪽으로 개방되므로 산소 용기에서 다시 산소가 공기 주머니 쪽으로 유입될 수 있으며, 일정량의 공기가 채워지게 되면 공기주머니 하단 밸브(11)는 다시 폐쇄된다.First, when the air bag 12 is compressed by the operator and the intake operation is performed, the intake / exhaust pipe control valve 15 installed at the branch point of the open oxygen supply pipe 14 is driven by the intake operation so that the air bag connecting pipe 35 ( That is, while opening the branch connected to the air bag 12, the exhaust pipe 30 (i.e., the branch connected to the exhaust valve 13) is closed, so that the exhalation pipe leading to the exhaust valve 13 The intake duct, which is blocked and leads to the air pocket 12, can be opened. After this operation, the air bag bottom valve 11 installed in the air bag 12 is also immediately opened to the air bag, so oxygen can flow back into the air bag from the oxygen container, and when a certain amount of air is filled, the air bag The bottom valve 11 is closed again.
반대로 배기 동작이 있게 되면 개방식 산소 공급관(14)의 분기 지점에 설치된 흡배기 관로조절밸브(15)는 호기 동작에 의해 흡기시와는 반대로 구동되어 배기 밸브(13)와 연결된 배출관(30)을 개방하면서 공기주머니 연결관(35)을 폐쇄하게 되고, 따라서 배기 밸브(13)로 이어지는 호기 관로는 개방되고 공기 주머니(12) 쪽으로 이어지는 흡기 관로는 폐쇄된다. 이러한 상태에서는 호기 가스가 배기 밸브(13)를 통해 외부로 방출될 수 있게 된다.On the contrary, when there is an exhaust operation, the intake and exhaust pipe line control valve 15 installed at the branch point of the open oxygen supply pipe 14 is driven opposite to the intake air by the exhalation operation to open the discharge pipe 30 connected to the exhaust valve 13. The air bag connection pipe 35 is closed, and thus the exhalation pipe line leading to the exhaust valve 13 is opened and the intake pipe line leading to the air bag 12 is closed. In this state, the exhalation gas can be discharged to the outside through the exhaust valve (13).

이와 같이 구성된 본 발명의 다른 실시 형태에 따른 인공 호흡장치의 사용 방법을 살펴보면 다음과 같다.Looking at the use of the respirator according to another embodiment of the present invention configured as described above are as follows.
먼저 시술자에 의해 공기 주머니(12)가 압축되어 흡기 동작이 있게 되면 순환식 산소 공급관(24)의 흡기 관로(24a) 상에 설치된 흡기 관로 조절밸브(25a)는 흡기 동작에 의해 개방되고 아울러 이때 배기 관로(24b) 상에 설치된 배기 관로 조절밸브(25b)와 배기 밸브(13)는 흡기 동작에 의해 폐쇄된 상태로 있게 되므로, 따라서 공기 주머니(12) 쪽에서 순환식 산소 공급관(24)으로 공급되는 산소 가스는 흡기 관로(24a)와 구강연결 관로(39)를 차례로 거쳐 환자 쪽으로 공급될 수 있게 된다. 특히 본 발명에 의한 인공 호흡장치를 소아 등에게 사용하는 경우, 흡기 관로(24a) 상에 설치된 대기 유입구(28)를 이용하여 소량의 대기 공기가 관로의 내부로 유입될 수 있도록 함으로써 흡기되는 산소의 농도를 조절하여 과도한 주입을 방지할 수 있게 된다.First, when the air bag 12 is compressed by the operator to perform the intake operation, the intake pipe control valve 25a installed on the intake pipe 24a of the circulating oxygen supply pipe 24 is opened by the intake air. Since the exhaust pipeline control valve 25b and the exhaust valve 13 provided on the pipeline 24b remain closed by the intake operation, the oxygen supplied to the circulating oxygen supply pipe 24 from the air bag 12 side is therefore provided. The gas can be supplied to the patient through the intake conduit 24a and the oral cavity conduit 39 in turn. In particular, when the ventilator according to the present invention is used in children, etc., a small amount of atmospheric air can be introduced into the conduit by using an air inlet 28 installed on the intake conduit 24a. The concentration can be adjusted to prevent excessive infusion.
이러한 동작이 이루어지고 나면 공기 주머니(12)의 선단부에 설치된 공기주머니 하단 밸브(11) 또한 즉시 공기 주머니 쪽으로 개방되므로 산소 용기에서 다시 산소가 공기 주머니 쪽으로 유입될 수 있으며, 일정량의 공기가 채워지게 되면 공기주머니 하단 밸브(11)는 다시 폐쇄된다.After this operation, the air bag bottom valve 11 installed at the front end of the air bag 12 is also immediately opened to the air bag, so oxygen can flow back into the air bag from the oxygen container, and when a certain amount of air is filled The air bag bottom valve 11 is closed again.
반대로 호기 동작이 있게 되면 순환식 산소 공급관(24)의 배기 관로(24b)에 설치된 배기 관로 조절밸브(25b)는 호기 동작에 의해 배기 밸브(13) 쪽으로 개방되고, 흡기 관로(24a) 상에 설치된 흡기 관로 조절밸브(25a)는 호기 동작에 의해 폐쇄된 상태로 있게 되므로, 따라서 환자와 구강연결 관로(39)와 배기 관로(24b)와 이산화탄소 흡수장치(27) 및 배기 밸브(13)로 이어지는 호기 관로가 개방되며, 이러한 상태에서 이산화탄소가 제거된 호기 가스는 필요에 따라 폐쇄 관로를 순환할 수 있게 되거나 또는 배기 밸브(13)를 통해 외부로 방출될 수 있게 된다.On the contrary, when there is an exhalation operation, the exhaust line control valve 25b installed in the exhaust line 24b of the circulating oxygen supply pipe 24 is opened toward the exhaust valve 13 by the exhalation action, and is installed on the intake line 24a. Since the intake pipeline control valve 25a is kept closed by exhalation operation, the exhalation leading to the patient and the oral cavity passage 39, the exhaust passage 24b, the carbon dioxide absorbing device 27 and the exhaust valve 13 is therefore performed. The conduit is opened, and in this state, the exhaled gas from which carbon dioxide has been removed can be circulated in the closed conduit as necessary or can be discharged to the outside through the exhaust valve 13.
이상과 같이 구성되는 본 발명에 의한 인공 호흡장치는 공기 주머니(앰브백)의 크기가 한 손으로 압축할 수 있는 정도의 크기이면서 적당한 양의 흡기 용량(예를 들면 1000 내지 1200 cc 정도)을 저장할 수 있게 되므로, 인공 호흡에 필요한 충분한 량의 흡기 용량의 조절이 가능하게 되며, 순환식 산소 공급관을 이용하여 산소의 효율적인 사용을 가능하게 하므로 산소의 소비량을 줄일 수 있고, 공기 주머니의 크기를 줄임으로써 복원력에 의한 에러도 줄일 수 있게 된다.The respirator according to the present invention constituted as described above is capable of compressing with one hand the size of an air bag (ambbag) and stores an appropriate amount of intake capacity (for example, about 1000 to 1200 cc). It is possible to adjust the intake capacity of the sufficient amount required for the artificial respiration, it is possible to reduce the consumption of oxygen and reduce the size of the air bag by enabling the efficient use of oxygen using the circulating oxygen supply pipe Errors due to resilience can also be reduced.
또한 본 발명에 의한 인공 호흡장치는 대기 유입구를 이용하여 대기공기의 유입량을 조절하여 환자에게 공급되는 산소를 원하는 농도로 조절할 수 있게 되므로 특히 소아 등에게 과도하게 주입되는 문제를 해결할 수 있게 된다.In addition, the ventilator according to the present invention can solve the problem of being excessively injected into children, because it is possible to control the oxygen supplied to the patient to the desired concentration by controlling the inflow of atmospheric air using the air inlet.
