[0038] The rear end of the cylinder wall 4 is provided with a battery slot and a transformer seat 7, and the rear end surfaces of the battery slot and the transformer seat 7 are provided with a switch A and a capacity setting device 8. A slider 5 is provided inside the cylinder wall 4, and the rear end of the slider 5 is connected to a connecting rod 17, and the rear end of the connecting rod 17 is provided with a grip and a resistive displacement sensor 9, and the rear end surfaces of the grip and the resistive displacement sensor 9 are provided with a button 10 including switches B and C;

[0039] The cylinder wall 4 is divided into two layers, an inner layer and an outer layer, and the outer layer and the outer layer are symmetrically provided with external coils 18 , and the inner layer and the inner layer are provided with internal coils 19 .

[0040] Preferably: the slider 5 is slidably connected to the cylinder wall 4, the slider 5 is connected to the connecting rod 17 by a thread, the internal coil 19 is embedded in the slider 5, and the slider 5 is used to cooperate with the cylinder wall 4 to extract a certain amount of gas; the scale line 6 is integrally formed on the cylinder wall 4, the front end base 3 is connected to the cylinder wall 4 by a thread, the scale line 6 is used for indication, and the front end base 3 is threaded to ensure sealing; the inlet check valve 1 and the outlet check valve 2 are threadedly connected to the front end base 3, the inlet pipe 11 and the outlet check valve 2 are interference fit, the inlet check valve 1 and the outlet check valve 2 are The valve 2 is used for one-way flow of gas; the air inlet pipe 11, the 120-degree elbow 12, the connecting seat 13, and the exhalation hole 15 are integrally formed, and a vertical downward component of force can be generated through the 120° angle of the 120-degree elbow 12 during advancement, which is helpful in assisting the other hand to fix the patient mask 16; the battery slot and the transformer seat 7 are connected to the cylinder wall 4 through threads, and batteries and transformers are installed inside the battery slot and the transformer seat 7, and the battery slot and the transformer seat 7 are used for power supply; a power cord is built into the connecting rod 17, and the connecting rod 17 is used for conduction.

[0041] Working principle: First, electromagnetic drive automatic reset: when power is turned on, the two sets of external coils 18 generate the same direction of magnetic field, and the electromagnetic force cooperates with the slider 5. There are many parallel and parallel internal coils 19 dispersed inside, which amplify the electromagnetic force when it acts. After power is turned on, it is subjected to the Lorentz force in the magnetic field, thereby achieving automatic reset.

[0042] Second, capacity control: before use, BC on the button 10 containing switches B and C is closed and switch A and A on the capacity setter 8 are disconnected. After setting the target volume, A is closed, and current is generated in the circuit. According to the electromagnetic cooperation between the external coil 18 and the internal coil 19, the slider 5 moves downward. Whether the set volume is reached needs to be judged by the resistive displacement sensor on the grip and the resistive displacement sensor 9. The sensor is divided into a sliding rheostat and a sensor. When the slider 5 moves downward, the resistance connected to the control circuit gradually decreases, and the current gradually increases. The sensor converts the set target volume into the current threshold of the control circuit through calculation. When the current increases to reach the threshold, the sensor controls C to disconnect, and there is no current in the drive circuit. At this point, the automatic recovery is completed. Subsequently, when manually advancing, the button 10 containing switches B and C is pressed at the same time, B changes from closed to disconnected, and C is closed again from disconnected, but there is still no current in the drive circuit. At this time, the gas in the cylinder wall 4 can be pushed out to the bottom without resistance. After releasing the hand, B returns to the closed state, and C remains closed, returning to the initial state. There are three reasons why manual advancement is used instead of manual pullback: 1. The rough ventilation flow rate can be controlled manually; 2. The patient's lung condition can be preliminarily judged by the resistance felt during advancement; 3. The downward force during advancement helps to fix the patient's mask 16;

[0043] The specific usage process is: by controlling the A, B, and C buttons, the internal coil 19 inside the control slider 5 is energized, and the magnetic force is used to move the slider 5 backward. At this time, a certain amount of gas is input into the cylinder wall 4 through the air inlet one-way valve 1. When the handle and the resistive displacement sensor 9 detect that the capacity is sufficient, the reverse direction is manually pushed. At this time, the air outlet one-way valve 2 is opened and the air inlet one-way valve 1 is closed, so that the gas supply inlet pipe 11 and the patient mask 16 reach the patient.
