The invention is further described below with reference to the figures and examples:

FIG. 1 is a schematic diagram of the overall structure of the present invention.

FIG. 2 is a schematic structural diagram of parts in a chest cavity of a model of the invention.

Fig. 3 is a schematic diagram of a control circuit of the present invention.

In the control circuit schematic diagram of the invention: a is a keyboard of a microcomputer controller; b is a rectification power supply; c, microcomputer chip: d is a driving circuit; e is a driving device; the IC is a microcomputer voice module; y is a loudspeaker; k is a switch; f is an electromagnetic valve.

The skin of the simulated human body model is molded and manufactured by a silica gel or vinyl mold, the subcutaneous tissue layer is manufactured by sponge, the model framework is manufactured by resin or plastic, the simulated lung/bronchial purulent sputum cavity is manufactured by plastic or silicone rubber, the simulated purulent sputum is manufactured by detergent and proper amount of yellow dye, other parts are sold in the market, and various parts are prepared, assembled and debugged according to the attached drawings and then can be used. When in use, the simulated purulent sputum is injected into the sputum storage tank from the sputum injection tube outside the high-simulation human body model by the large injector. Because this pipe is equipped with the simulation purulent sputum that one-way check valve so injected can not flow out, along with annotating the increase of phlegm volume, store the gradual rise of sputum flask liquid level, the air in the bottle is discharged through leading to the overflow pipe outside the model, indicates to have filled when the overflow pipe has the simulation purulent sputum to spill over, can stop to pour into the simulation purulent sputum this moment into. When the body position is drained, a power supply is connected, a power switch on a panel of a microcomputer controller is turned on, a voice module is automatically switched on to enable a loudspeaker to send out a voice prompt of 'please select a drainage position', according to teaching requirements, a drainage position key is selectively pressed in 'upper left', 'middle left', 'lower left', 'upper right', 'middle right' and 'lower right' position keys arranged on the panel, the voice module is automatically switched on to enable the loudspeaker to send out the voice prompt of 'setting the drainage position and please wait', a driving circuit controlled by a microcomputer chip is used for switching on an electromagnetic valve connected with a lung/bronchus purulent cavity of the selected drainage position, a micro air pump and a micro water pump power supply arranged on the abdomen of a model are simultaneously switched on, the micro air pump automatically injects air into an air storage tank and injects simulated purulent liquid into the cavity, when the air pressure in the air storage tank reaches the rated pressure, a tank pressure sensor trigger signal is transmitted to the microcomputer, the micro air pump is controlled by a driving circuit after being processed by a microcomputer chip, so that the micro air pump is powered off and stopped; the simulation pus sputum injection simulation pus sputum chamber in the sputum flask is stored in automatic extraction of miniature pump, the air of this intracavity passes through total exhaust pipe through the blast pipe and discharges, when simulation pus sputum in the pus sputum chamber is annotated fully, the magnetic sheet at this simulation pus intracavity floats the box top along with the pus sputum liquid level come-up gradually, when the magnetic sheet is close the hall sensor that the cavity highest point outside set up, triggering signal handles through the microcomputer chip promptly, the solenoid valve outage that makes this pus sputum chamber connect is closed, make the injection simulation pus sputum miniature pump outage stoppage in transit simultaneously, and put through voice module automatically and make the speaker send "drainage position and set up and finish, ask for the voice prompt of position drainage". Because the micro air pump and the micro water pump are both connected with the one-way check valve, the phenomenon of reverse flow during sputum or gas injection can be effectively prevented. If the operator operates the body position drainage body position correctly, the position sensor switch of the purulent sputum cavity automatically switches on the power supply of the electromagnetic valve through a driving circuit controlled by a microcomputer to open the electromagnetic valve, the simulated purulent sputum in the purulent sputum cavity enters the side simulated bronchus through the electromagnetic valve and a catheter connected with a liquid outlet under the action of gravity, and then is drained into the simulated trachea, when the simulated trachea is filled with the simulated purulent sputum, because the yellow purulent sputum is not transparent, a triggering signal of the optical coupler sensor on the outer wall of the trachea is processed through the microcomputer chip, namely, the voice module for simulating cough sound is automatically switched on, so that a loudspeaker at the pharyngeal portion sends out cough sound, then when the cough is delayed for several seconds, the large electromagnetic valve for simulating the throat and the electromagnetic valve for a gas storage tank communicated with the simulated trachea are automatically switched on, when the two valves are simultaneously opened, the high-pressure air in the tank enables the, the simulated scene is very vivid after being sprayed out of the model port of the high-simulation human body. If the drainage body position is incorrect during operation, no purulent sputum is drained into the trachea, and no cough sound or purulent sputum is coughed out. The body position drainage training and examining device is used for training and examining body position drainage skills of medical students and medical staff in work in medical colleges and hospitals, and can obviously improve the teaching quality.
