Description

산소 호흡기Oxygen respirator

제1도는 본 고안의 사시도1 is a perspective view of the present invention

제2도는 본 고안의 종단면도2 is a longitudinal cross-sectional view of the present invention

제3도는 본 고안의 요부인 오버밸브의 작동상태를 나타낸 발췌 단면도3 is a cross-sectional view showing the operating state of the over valve, which is the main part of the present invention

본 고안은 비상시나 화재진화 작업시에 사용하는 산소 호흡기에 관한 것으로, 산소주머니에 오버밸브를 형성하여 안전을 도모할 수 있도록 한 것이다.The present invention relates to an oxygen respirator for use in an emergency or fire extinguishing operation, and is intended to provide safety by forming an overvalve in an oxygen bag.

지금까지 사용되어온 산소 호흡기로는 액체 산소를 저장하여 산소를 공급하도록 구성된 것과 과산화나트륨이 주성분인 고체산소를 기화한 다음 산소주머니에 저장하여 산소를 공급하도록 구성된 것이 있는데, 액체산소를 사용하는 전자의 산소호흡기는 통상적으로 안전밸브가 부착되어 있으나 고체산소와 산소주머니를 이용하는 후자의 산소호흡기는 안전밸브가 없이 사용되어 왔다.Oxygen respirators that have been used up to now are configured to store liquid oxygen to supply oxygen and to vaporize solid oxygen mainly composed of sodium peroxide and to store oxygen in an oxygen bag to supply oxygen. Oxygen respirators are usually equipped with safety valves, but the latter oxygen respirators using solid oxygen and oxygen bags have been used without safety valves.

그런데 전자의 것은 구조가 복잡하고 제작비가 무척 비싼 단점이 있으며, 후자의 것은 산소주머니의 압력이 알맞지 않으면 사용자가 자연스런 호흡을 할 수 없는데 이 산소주머니의 내압을 자동 조절하는 장치가 없는것이 큰 단점이었다.However, the former has a disadvantage in that the structure is complicated and the manufacturing cost is very expensive. In the latter, the user cannot breathe naturally if the pressure of the oxygen bag is not appropriate, but there is no device for automatically adjusting the internal pressure of the oxygen bag. .

본 고안은 이러한 점을 감안하여 값이싸고 구조가 간단한 후자의 산소호흡기의 단점인 산소주머니의 부적당한 내압을 호흡하기에 가장 절절한 압력으로 유지되도록 안출한 것으로, 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been designed to maintain the most appropriate pressure to breathe the improper internal pressure of the oxygen bag, which is a disadvantage of the latter oxygen inhaler, which is inexpensive and simple in structure. As follows.

즉 흡기구(1)와 배기구(2)를 형성하고 산소주머니(3)를 보호통(4)에 내장한 통상이 산소호흡기에 있어서, 산소주머니(3)의 일 측면에 통기공(5)과 관통공(6)을 천공하여 관통공(6)에 H형의 개폐판(7)을 스프링(8)으로 탄설하여 개폐판(7)의 좌단은 통기공(5)을 개폐토록 하고 우단은 보호통(4)의 내측면에 접리되도록 구성한 것으로, 미설명부호 9는 고체산소이고 10은 고체산소의 조임구, 11은 별도의 마스크와 연결되는 고무호스이다.That is, in the oxygen respirator, in which the inlet port 1 and the exhaust port 2 are formed and the oxygen bag 3 is incorporated in the protective container 4, the vent hole 5 and the through hole are provided on one side of the oxygen bag 3. (6) bores the through hole (6) H-shaped opening plate (7) with a spring (8), the left end of the opening and closing plate (7) to open and close the vent hole (5) and the right end is a protective tube (4 The reference numeral 9 denotes a solid oxygen, 10 denotes a fastener for solid oxygen, and 11 denotes a rubber hose connected to a separate mask.

이와 같이 구성된 본 고안은 일단 산소주머니(3)에 고체산소(9)에서 용해된 적당량의 기체산소를 유입한 다음 별도의 마스크와 연결된 고무호스(11)를 흡기구(1)와 배기구(2)에 연결하여 사용하는 것으로 산소주머니(3)에 유입된 산소량이 과다하여 호흡에 지장을 초래할 염려가 있을 경우에는 탄서의 산소주머니(3)가 팽대되면서 제3b도와 같이 보호통(4)의 내벽에 가까와지면 개폐판(7)의 우단이 보호통(4)의 내벽에 걸려 더 이상 나아가지 못하는 한편 산소주머니(3)는 계속 스프링(8)을 이기고 내압(P)에 의해 화살표 방향으로 이동하기 때문에 개폐판(7)의 좌단에 의해 막혀있던 통기공(5)이 열려 산소주머니(3)내의 산소는 통기공(5)을 통해 배기되므로 산소주머니(3)의 내압이 떨어지며 산소주머니(3)의 내압이 호흡에 적당하게 되면 산소주머니(3)가 다시 보호통(4)내벽으로 부터 떨어져 나오므로 스프링(8)의 탄력에 의해 개폐판(7)의 좌단이 제3a도와 같이 통기공(5)을 막아주어 정상 작동하게 되는 것이다.According to the present invention, the oxygen bag 3 is introduced with an appropriate amount of gaseous oxygen dissolved in solid oxygen (9), and then a rubber hose (11) connected to a separate mask is connected to the inlet port (1) and the exhaust port (2). If there is a risk of excessive oxygen flow into the oxygen bag (3) and cause respiratory problems, the oxygen bag (3) of the tancer expands and approaches the inner wall of the protective container (4) as shown in FIG. While the right end of the opening and closing plate 7 is caught by the inner wall of the protective container 4 and can no longer proceed, the oxygen bag 3 continues to overcome the spring 8 and moves in the direction of the arrow by the internal pressure P. The vent hole 5 blocked by the left end of 7) is opened and the oxygen in the oxygen bag 3 is exhausted through the vent hole 5 so that the internal pressure of the oxygen bag 3 drops and the internal pressure of the oxygen bag 3 is respirated. Oxygen bag (3) is protected again Since the cylinder 4 is separated from the inner wall, the left end of the opening and closing plate 7 blocks the vent hole 5 by the elasticity of the spring 8 to operate normally.

이와 같이 작동하는 본 고안은 스프링(8)의 탄력만 잘 조정하면 산소주머니(3)의 내압이 항시 자동조절되기 때문에 구조가 간단하면서도 사용상 매우 편리한 특징을 지닌 것이다.The present invention works as described above, because the internal pressure of the oxygen bag (3) is always automatically adjusted if only the elasticity of the spring (8) is adjusted, the structure is simple but very convenient in use.
