  However, in the conventional lifesaving device, since the on / off valve 51 is fixed to the pressure regulator 50, it is necessary to have the pressure regulator 50 and the on / off valve 51 together, which is heavy and difficult to use. .

  In addition, there is a problem that it is difficult to place the pressure regulator 50 and the on / off valve 51.

  If the secondary pressure is excessively increased, it is necessary to release the oxygen gas in the secondary chamber of the pressure regulator 50 by loosening the pressure adjustment handle 50b and pressing the push button 51a of the on / off valve 51. At that time, since the oxygen gas is released through the tube 53 and the injection needle, the tube 53 and the injection needle jump by the force of the oxygen gas, which is dangerous.

  Therefore, the main purpose of this invention is to provide an easy-to-use and safe life-saving device.

  Also preferably, a tube having one end connected to the second gas outlet, a base end connected to the other end of the tube, and a distal end punctured into the trachea of the patient, A needle for supplying the respiratory gas provided through the part into the trachea of the patient.

  In the lifesaving device according to the present invention, the first gas inlet of the pressure regulator is fixed to the socket of the pipe terminal via the gas plug, and the first gas outlet of the pressure regulator is connected to the second on / off valve via the hose. A respiratory gas is supplied into the patient's trachea from the second gas outlet of the on / off valve, which is connected to the gas inlet. Therefore, since the user only needs to hold the ON / OFF valve, it is light and easy to use, and there is no trouble in storing the pressure regulator.

  When the pressure regulator releases the respiratory gas in the secondary chamber to the outside in response to the release of the pressure adjusting handle, even if the pressure of the respiratory gas in the secondary chamber is excessively increased. Second, the respiratory gas in the secondary room can be easily and safely released.

  Further, when a tube and an injection needle are further provided, even when tracheal intubation is difficult, respiratory gas can be supplied into the patient's trachea.

The proper use range (0.14 MPa to 0.35 MPa) of the dial is given a predetermined color.

  A primary chamber A communicating with the gas inlet and partitioned by the valve seat 17 and a secondary chamber B communicating with the gas outlet and the pressure gauge 1a and covered with the diaphragm 18 are formed inside the regulator body 15. ing. An adjustment valve 19 is arranged in the primary chamber A. The adjustment valve 19 is urged toward the valve seat 17 by a buffer spring 20 and closes a valve hole at the center of the valve seat 17. A relief valve 21 is disposed in the secondary chamber B. An adjustment valve guide rod 22 is movably provided in the valve hole of the valve seat 17. One end of the adjustment valve guide rod 22 is fixed to the adjustment valve 19, and the other end is fixed to the relief valve 21. The relief valve 21 is urged toward the diaphragm 18 by the buffer spring 20 via the adjustment valve 19 and the adjustment valve guide rod 22, and closes a relief hole at the center of the diaphragm 18.

  An adjuster cover 23 is provided so as to cover the diaphragm 18. The adjuster cover 23 is formed with a relief hole 23a. In the adjuster cover 23, a diaphragm receiver 24 which is in contact with the back surface of the diaphragm 18 and a pressure adjusting spring 27 sandwiched between two spring receivers 25 and 26 are accommodated. A push screw 28 is screwed to an end of the adjuster cover 23, and a distal end of the push screw 28 abuts against the back surface of the spring receiver 26, and a base end of the push screw 28 is located at the center of the pressure adjusting handle 1b. Fixed.

  Next, the operation of the pressure regulator 1 will be described. When the gas plug 2 is inserted into the socket 4, the gas plug 2 is locked by the socket 4, and oxygen gas is supplied to the gas inlet of the pressure regulator 1 via the gas plug 2. At this time, since the regulating valve 19 is urged to the valve seat 17 by the buffer spring 20, the oxygen gas fills the primary chamber A as shown in FIG.

  When the pressure adjustment handle 1b is turned clockwise with the on / off valve 6 closed, the pressure adjustment spring 27 is compressed and the diaphragm 18 is pushed down as shown in FIG. 5B. In response to the movement of the diaphragm 18, the relief valve 21 and the regulating valve 19 are pushed down in conjunction with each other, so that a gap is formed between the regulating valve 19 and the valve seat 21, and oxygen gas enters the secondary chamber B.

  At the next moment, the pressure in the secondary chamber B increases, and as shown in FIG. 5C, the diaphragm 18 is pushed up and the adjustment valve 19 is closed. When the on / off valve 6 is opened to supply oxygen gas, the operations in FIGS. 5B and 5C are repeated. In the state shown in FIG. 5C, a state in which the force of pressing down the pressure adjusting spring 27, the pressure of the secondary chamber B, the pressure of the primary chamber A, and the force of the buffer spring 20 are maintained through the diaphragm 18. It has become. Therefore, the pressure of the secondary chamber B can be adjusted to a desired value by adjusting the degree of tightening of the pressure adjustment handle 1b.

  Here, when the pressure adjustment handle 1b is turned in the counterclockwise direction, the force of the pressure adjustment spring 27 is weakened, and the balance of the right and left forces via the diaphragm 18 is lost. As shown in FIG. It is pushed up by the pressure of the secondary chamber B. Since the regulating valve 19 is in contact with the valve seat 17, a gap is formed between the relief valve 21 and the diaphragm 18, and oxygen gas in the secondary chamber B is supplied to the outside through the relief hole of the diaphragm 18 and the relief hole 23 a of the regulator cover 23. Will be released. Since the oxygen gas is released, the pressure in the secondary chamber B decreases, and as shown in FIG. 5E, the diaphragm 18 is pushed by the force of the pressure adjusting spring 27, and the relief valve 21 is closed.

  Therefore, by using the pressure regulator 1, even if the pressure in the secondary chamber B is excessively increased, the pressure in the secondary chamber B can be reduced and readjusted with the on / off valve 6 closed. Therefore, there is no need to release the oxygen gas in the secondary chamber B via the tube 7 and the injection needle 8, so that the tube 7 and the injection needle 8 do not bounce with the force of the oxygen gas and are safe.

  FIGS. 6A and 6B are views showing the appearance of the on / off valve 6, and FIG. 7 is a sectional view showing the configuration of the on / off valve 6. Referring to FIGS. 6A and 6B and FIG. 7, the on / off valve 6 includes a valve body 30 formed by processing a cylindrical metal piece. A concave portion 31 having a predetermined dimension is formed on the upper surface of the valve body 30, and a gas inlet and a gas outlet are formed on both side surfaces of the valve body 30, respectively.
