Working principle: when a patient experiences shock or symptoms that result in dyspnea, a secondary breath is required to allow the patient to resume breathing.

When the patient is assisted in breathing, the upper end of the elastic hook 407 is pulled to a side far from the central axis of the fixing post 406, so that the flexible tube 403 is removed from the elastic hook 407, and then the mask 404 to which the flexible tube 403 is connected is fixed to the face of the patient. Since the elastic hook 407 has elasticity, even if the elastic hook 407 is pulled, the elastic hook 407 is not broken, and the elastic hook 407 can clamp the flexible tube 403 in a natural state, so that the mask 404 and the flexible tube 403 are fixed.

After the mask 404 is fixed on the face of the patient, the oxygen bottle 301 is started, so that the gas in the oxygen bottle 301 for the patient to breathe enters the temperature regulating box 303 through the gas pipe 302, then enters the connecting pipe 402 through the gas pipe II 405 connected with the temperature regulating box 303, then enters the flexible pipe 403 through the connecting pipe 402, finally, the gas enters the patient through the flexible pipe 403 and the mask 404, and the breathing of the patient is assisted.

When the temperature of the gas coming out of the oxygen bottle 301 needs to be raised, the heating wire inside the temperature adjusting box 303 can be started, and other gases can be heated through the heating wire. Of course, heating by means of heating wires is known in the art and can be achieved by a person skilled in the art.

When the flow rate of the gas passing through the gas pipe 302 needs to be regulated, according to the requirement of actually controlling the flow rate, the first regulating rod 306 or the second regulating rod 307 can be pressed downwards, that is, the pressing head 319 fixedly mounted on the first regulating rod 304 is pressed, and the first regulating rod 306 and the second regulating rod 307 have the same working principle, and the first regulating rod 306 is used for limiting the flow rate of the gas for illustration.

Pressing the pressing head 319 to enable the pressing rod 304 fixed below the pressing head 319 to push the first adjusting rod 306 to slide downwards along the U-shaped frame 305 (as shown in fig. 11), the pressing rod 304 slides downwards along the box body 1, a reset spring six between the pressing rod 304 and the inside of the box body 1 is stretched, the reset spring six is used for assisting in resetting of the pressing rod 304, the outer diameter of the first adjusting rod 306 is equal to the inner diameter of the first round hole 315, in an initial state, the lower end of the first adjusting rod 306 is tightly attached to the first round hole 315, namely, only three thin rods 310 are positioned in the inside of the gas pipe 302 in the initial state, the first round hole 315 is plugged in the initial state of the first adjusting rod 306, and other leakage is prevented; when the first adjusting rod 306 slides downward, the first adjusting rod 306 slides downward along the first circular hole 315, the first adjusting rod 306 enters the air pipe 302, and the diameter of the first adjusting rod 306 is larger than that of the thin rod 310, so that when the air flows in the air pipe 302, the air encounters a larger barrier than the thin rod 310, thereby reducing the air flow, and the air entering the flexible pipe 403 is reduced. When the first adjusting rod 306 slides downwards, the thin rod 310 also slides downwards along the fourth round hole 318, in this process, the fourth return spring 309 is stretched, the fourth return spring 309 is used to assist in resetting the thin rod 310, and the outer diameter of the thin rod 310 is equal to the inner diameter of the fourth round hole 318, so that the lower end of the air pipe 302 cannot leak air.

When the first adjusting lever 306 slides downward, the short lever 320 fixedly mounted on the first adjusting lever 306 slides along the sliding groove 312 on the plate 311, the short lever 320 slides over the inclined surface above the sliding groove 312 (as shown in fig. 13), then the short lever 320 slides over the vertical portion of the sliding groove 312, during this process, the plate 311 slides leftward along the U-shaped frame 305 (based on the direction of fig. 13), and the sliding groove 312 opposite to the first adjusting lever 306 is provided with the boss 313, so that the short lever 320 is clamped by the plane below the boss 313, after the short lever 320 is clamped, the first adjusting lever 306 is also clamped, and at this time, the pressing head 319 is released, thereby maintaining the current-limiting function of the first adjusting lever 306, and the function of the fifth return spring 314 is to assist in resetting the plate 311. It should be noted that the U-shaped frame 305 is provided with a groove identical to the sliding groove 312, and the short rod 320 is slidably engaged with the groove on the U-shaped frame 305 while passing through the sliding groove 312.

When the restriction state of the first regulating rod 306 needs to be released, the reset rod 308 moves downward, specifically, the pressing head 319 above the reset rod 308 is pressed downward, so that the pressing head 319 drives the pressing rod 304 and the reset rod 308 to move downward, the reset rod 308 slides downward along the U-shaped frame 305 and the round hole three 317 on the air delivery pipe 302, the short rod 320 fixedly connected to the reset rod 308 slides downward, at this time, the short rod 320 on the reset rod 308 passes through the inclined surface above the sliding groove 312 and then slides through the vertical part on the sliding groove 312 via the short rod 320, the plate 311 slides leftward (based on the direction of fig. 13) along the U-shaped frame 305, after the plate 311 moves leftward, the sliding groove 312 opposite to the first regulating rod 306 also moves leftward, so that the short rod 320 on the first regulating rod 306 leaves the boss 313, i.e. the short rod 320 is no longer blocked by the boss 313, and the opposite sliding groove 312 on the reset rod 308 is not provided with the boss 313, at this time, the pressing head 319 is released, the reset rod 308 and the first regulating rod 306 moves upward, and the first regulating rod 306 stretches into the inner part of the air delivery pipe 302 to contact the air delivery pipe 302.

When the patient is required to be administered while breathing, such as narcotics, pain relieving drugs, etc., the administration of the drug is required through the drug delivery mechanism 2.

The amount of the medicine to be introduced into the first air tube 401 can be flexibly selected according to the amount of the medicine to be supplied when the medicine is supplied by the medicine supplying mechanism 2.

When selecting the amount of drug to be administered, the hand wheel 226 is first turned so that the pointer on the hand wheel 226 points to the scale on the dial 225, with different scales representing different drug delivery capacities. When the hand wheel 226 is rotated, the rotating rod 220 fixedly connected with the hand wheel 226 rotates in the box 1, when the rotating rod 220 rotates, the two symmetrically arranged cylinders 219 fixedly arranged on the rotating rod 220 rotate, and the horizontal grooves 221 and the convex grooves 222 are arranged on the cylinders 219, so that when the cylinders 219 rotate, the horizontal grooves 221 and the convex grooves 222 on the convex grooves 222 intermittently pass through the guide rods 218, when the horizontal grooves 221 and the guide rods 218 slide relatively, the guide rods 218 can keep unchanged in height, and when the convex grooves 222 rotate to be in contact with the guide rods 218 and slide relatively, the height of the guide rods 218 changes, and the guide rods 218 between the driven gears 208 and the driven gears 209 are taken as an example.
