Description

[Detailed Description of the Invention] Purpose of the Invention The present invention relates to an emergency respirator for resuscitating a drowning person or other suffocating person. The purpose is to enable artificial respiration in a clean and hygienic manner.

Conventional technology Currently, as an emergency method of artificial respiration, the operator either blows air directly from mouth to mouth, or inserts a pipe with a mouth-occluding cover into the mouth of the suffocating person and sends air through the pipe. It is.

However, with this type of system, the air pressure injected causes the filth in the stomach of the suffocated person to flow backwards, and this vomit causes discomfort to the person administering artificial respiration, and can also cause infection if the suffocated person is a carrier. There is a flaw that it is extremely unsanitary and there is a risk that it will cause damage.

Structure of the Invention The present invention is an attempt to improve such defects in the conventional art with an extremely simple structure. The lower end of the pipe is connected to the blowing pipe through a liquid storage chamber, and within the above-mentioned upper and lower branch pipes is a moving switching valve that normally falls by gravity to close the lower end and rises by the blowing force to close the upper end. The gist is that it is provided so that it can be moved up and down.

An embodiment of the present invention will be described with reference to the drawings. A central portion of an upper and lower branch pipe 3 is connected to a bent portion at the upper end of an insertion pipe 2 which has a mouth-occluding cover 1 and whose lower part is curved so as to be easily inserted into the mouth. At the same time, the upper end of the upper and lower branch pipes 3 is connected to a small-diameter exhaust pipe 4, and the lower end is rotatable via a small-diameter connecting pipe 5 and has a liquid reservoir chamber 7 having a minute liquid drain hole 6.
The liquid reservoir chamber 7 is further connected to a blow pipe 8 extending upward.

The inside of the upper and lower branch pipes 3 is normally locked by gravity to the small-diameter connecting pipe 5 to close the lower end, and is blown upward by the blowing force of the blowing pipe 8 into the exhaust pipe 5. A spherical movable switching valve 9, which is engaged with and closes the upper end portion, is enclosed so as to be vertically movable.

Since the embodiment of the present invention is constructed as described above, the lower end of the insertion pipe 2 is inserted into the mouth of a suffocating person, the mouth is closed with the mouth closing cover 1, and the blowing pipe 8 is
When the person administering artificial respiration blows in air from the upper end, the air passes through the liquid reservoir chamber 7 and pushes up the moving switching valve 9 of the upper and lower branch pipe 3 to the upper end of the upper and lower branch pipe 3, closing it and at the same time, the insertion pipe 2 and is sent to the lungs of the suffocated person, and when the air has finished being blown, the movable switching valve 9 falls to the bottom due to gravity and is locked to the connecting pipe 5, closing the lower end of the branch pipe 3. Therefore, the exhaust air and vomit from the lungs are discharged from the insertion pipe 2 through the upper and lower branch pipes 3 to the exhaust pipe 4, and the saliva of the patient and some of the vomit of the suffocated person are discharged to the lower end of the upper and lower branch pipes 3. Even if the liquid gets into the liquid storage chamber 7, it will be discharged from the liquid drainage hole 6.

However, in the case of levering, if the blowing pipe 8 is made rotatable by the connecting pipe 5 as in the embodiment, it is convenient because the operator can freely move left and right even in a narrow space such as inside a ship.

In the embodiment described above, the upper and lower branch pipes 3 are closed using the exhaust pipe 4 and the connecting pipe 5, each having a small diameter, but they may be closed by separately providing a locking valve seat.

Effects of the Invention The present invention provides an upper and lower branch pipe connected to the upper end of the insertion pipe, connects the lower end of the upper and lower branch pipe to the blowing pipe via a liquid reservoir chamber, and closes the lower end part within the upper and lower branch pipe by gravity. A movable switching valve that closes the upper end with a blowing action is enclosed, so the exhaust air and vomit of a suffocated person are discharged from the upper end of the upper and lower branch pipes into the exhaust pipe, and some of the filth and saliva of the operator are also removed. Since the liquid is stored in the liquid storage chamber and discharged, the person performing artificial respiration can perform artificial respiration without being contaminated by the vomit of a suffocated person, causing discomfort or unsanitary conditions. Its structure is also extremely simple and has the excellent features of being conveniently portable.

Claims (1)

[Claims] 1. Connect the upper end of the insertion pipe with the port closing cover to the center of the upper and lower branch pipes, and connect the lower ends of the upper and lower branch pipes to the blowing pipe via the liquid reservoir chamber, and the gravity inside the upper and lower branch pipes is normally maintained. This emergency respirator is equipped with a movable switching valve that can be moved up and down, which closes the lower end when it falls and closes the upper end when it rises due to the blowing force.
