Description

[Detailed Description of the Invention] This invention relates to an oxygen inhalation valve for a hyperbaric chamber used in a hyperbaric oxygen treatment room.

The purpose of this invention is to create an improved hyperbaric chamber oxygen system that allows the patient to insert a vacuum tube into the patient's airway to relieve sputum blockage while the patient is wearing a band mask and inhaling oxygen. The purpose is to provide an intake valve.

In other words, oxygen inhalation masks for patients receiving treatment in hyperbaric oxygen treatment rooms must be monitored from outside so that there is no risk of them falling off, and they must be worn as band masks so that they fit tightly against the face and must be taken on and taken off frequently. has an unsuitable configuration. On the other hand, many patients who are inhaling oxygen produce a lot of phlegm, which clogs their airways, so the use of vacuum tubes is essential.

However, conventional oxygen inhalation valves for hyperbaric chambers require the oxygen inhalation mask to be removed when using the vacuum tube, which is inconvenient and inadequate as an emergency measure against sputum blockage. It wasn't.

This invention overcomes the above-mentioned drawbacks of the prior art.
This was done for the purpose of solving a problem. The ultimate goal of this invention is to form the joint tube section for attaching the band mask or endotracheal intubation adapter in a direction approximately perpendicular to the main tube section, and to form the joint tube section in the direction of extension of the joint tube section. An object of the present invention is to provide an oxygen inhalation valve for a high pressure chamber, which has a tube insertion socket formed therein and a breathing safety valve unit detachably attached to the vacuum tube insertion socket.

Next, this invention will be explained with reference to illustrated embodiments.

FIG. 1 shows the entire oxygen suction valve for a high pressure chamber according to this invention. In the figure, 1 is an oxygen tube that introduces oxygen from an oxygen supply source, 2 is a reservoir bag located at one end of the oxygen inhalation device, and the oxygen tube 1 is connected to an adapter 3 of the reservoir bag. Reservoir bag 2 is made of ultra-thin polyethylene film, etc., which has a capacity of about 5 and is shaped into a spherical shape when expanded.It is extremely light and deforms in response to changes in breathing pressure. Therefore, it has the advantage that the patient's breathing condition can be easily grasped and understood by monitoring from outside the hyperbaric room through a pressure-resistant window or monitor television.

The adapter 3 of the reservoir bag 2 has a connector 4
The other end of the elbow 5 is connected to a cross pipe 7 via a connector 6, forming a series of pipes.
The joint pipe portion 7 is formed in a direction substantially perpendicular to the
An adapter 9 for a band mask 8 is inserted and attached to the adapter 9 at b. An endotracheal intubation tube (not shown) can be connected to this adapter 9 instead of the band master 8. Also, in the cross tube 7, a vacuum tube insertion socket 7c formed in the extension direction of the joint tube portion 7b has a socket portion 16 of a breathing safety valve unit 10 detachably attached thereto. Therefore, the band mask 8 is located at the other end of the oxygen inhalation valve, symmetrically to the safety valve unit 10.

FIG. 2 shows details of the configuration of the main parts. First, a suction valve 11 that opens only in the oxygen suction direction is installed at the end of the elbow 5 facing the cross pipe 7. In the figure, 12 is a stopper that defines the closed position of the suction valve 11. In the main pipe portion 7a of the cross pipe 7, a mesh filter 13 is provided at the end opposite to the elbow 5.
is installed, so that even if the suction valve 11 becomes detached, there is no risk of it entering the patient's airway. Also,
An exhalation valve 14 for discharging the patient's breath is installed at the other end of the main pipe portion 7a. 15 in the diagram
is a stopper that defines the closed position of the exhalation valve 14.

Next, the breathing safety valve unit 10 has an exhaust port 102 in the top wall of the case 101 forming the valve chamber.
An exhalation valve plate 103 that opens and closes this is installed on the outer surface of the top wall. In addition, a suction valve plate 105 is attached to the lower end of the cylindrical portion 104 that is formed to hang inward from the top wall.
is installed. A valve stem 108 is passed through a bearing 107 supported by an arm 106 at the center of the cylindrical part 104, and spring bearings 10 are attached to the upper and lower ends of the valve stem 108.
A push spring 100 is provided between the spring receiver 109 and the exhalation valve plate 103 and the suction valve plate 105.
is installed. The exhalation valve plate 103 also has a relatively large diameter shaft hole 11 through which the valve stem 108 passes.
0 is formed, allowing outside air to flow into the cylindrical portion 104. The lower end of this cylindrical portion 104 forms an inlet 111 .

The strength of the push spring 100 is slightly greater than the opening/closing resistance of the inhalation valve 11 and exhalation valve 14. The case 101 is integrally formed with a socket portion 16 which is detachably attached to the vacuum tube insertion socket 7c.

Therefore, under normal conditions, the breathing safety valve unit does not work. However, when the opening and closing operations of the inhalation valve 11 and exhalation valve 14 are malfunctioning and the patient's breathing resistance increases, or when the oxygen supply is insufficient due to a sudden change in the high pressure room pressure, or when the If it is disconnected, the intake valve plate 105 or exhalation valve plate 103 of the respiratory safety valve unit 10, the exhaust port 102 or the intake port 111
opens and closes to allow the patient to breathe easily,
This prevents suffocation and ensures safety. That is, when the pressure in the high-pressure chamber increases rapidly and the reservoir bag 2 is compressed and a large amount of oxygen flows into the cross tube 7, the pressure inside the case 101 becomes high and the exhalation valve plate 103 is pressed against the elasticity of the spring 100. The oxygen in the cross tube 7 flows out from the exhaust port 102. This is particularly effective when the exhalation valve 14 does not open sufficiently due to a malfunction or the like.

Further, when the pressure in the high pressure chamber suddenly decreases, the pressure in the reservoir bag 2 decreases, and when oxygen is no longer supplied sufficiently, the inside of the case 101 becomes negative pressure, and the suction valve plate 105 opens against the push spring 100. Air in the high pressure chamber flows in through the suction port 111 and the shaft hole 110, allowing the patient to breathe.
The same effect occurs when the suction valve 11 does not open normally.

In addition, the relative positional relationship between the elbow 5 and the reservoir bag 2 with respect to the manner of use of the band mask 8 is as follows.
Adjustment can be made over a wide range by adjusting the rotation angle during connection using the connectors 4 and 6.

This oxygen inhalation valve is the third valve for the patient.
It is used in the manner shown in the figure. If, during use, the patient exhibits symptoms such as clogging of the respiratory tract with phlegm or saliva, leave the band mask 8 in place and quickly remove the respiratory safety valve unit 10 and insert the vacuum tube insertion socket 7c that has been opened. Vacuum tube 18 is inserted into the patient's mouth or airway through the joint tube portion 7b.
can be inserted to cleanly remove obstructive phlegm or saliva.

Note that in the above description, the band mask is attached to the patient's face, but this is not the case.

That is, the same effects can be expected even when the tube is configured as a tracheostomy tube applied to oxygen inhalation through tracheotomy.

Since this invention is based on the oxygen suction valve for a high pressure chamber having the configuration described above, it has the following effects.

In other words, when a patient wearing a band mask and breathing in oxygen exhibits symptoms of airway obstruction due to phlegm or saliva, the vacuum tube can be used immediately by simply removing the respiratory safety valve unit. It can relieve airway blockage caused by phlegm and saliva and prevent suffocation.
In case of oxygen supply problems caused by sudden changes in atmospheric pressure (pressure) in the hyperbaric chamber, the exhalation valve plate or inhalation valve plate of the respiratory safety unit opens and air from the hyperbaric chamber flows in, preventing the patient from suffocating.
