Detailed ways

In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be introduced in further detail below with reference to the accompanying drawings.

The embodiment of the utility model discloses an adjustable respiratory function training device.

The utility model provides an adjustable respiratory function trainer as shown in Figures 1, 3, 4 and 5, which includes an air chamber 1, an exhalation nozzle 2 installed in the air chamber 1, an observation box 3, and an opening of the air chamber 1. The gas delivery bin 4, as well as the restriction tube 5 and valve 6 installed in the gas delivery bin 4, the restriction tube 5 is provided with a ventilation bin 7, and a restriction component is installed inside the ventilation bin 7. The restriction component includes a ventilation ring 8, and the ventilation ring 8 is fixedly installed. Inside the ventilation chamber 7, a dust-proof shell 9 is fixedly installed on the side of the ventilation ring 8 close to the exhalation nozzle 2. A spring 10 is provided inside the dust-proof shell 9, and a push rod 11 is fixedly connected to the inner side of the spring 10. A ventilator 12 is fixedly connected to the outside of 11, and a cone head 13 is fixedly connected to the side of the ventilator 12 away from the ventilator ring 8. Compared with the traditional method, it can effectively prevent the inhalation of breathed air, reduce errors, and ensure accurate data display.

When in use, insert the exhalation nozzle 2 into the restriction cylinder 5 in the air delivery chamber 4. After confirming that the connection is completed, open the valve 6, open the device, align the exhalation nozzle 2 and exhale, and the gas will enter through the exhalation nozzle 2. In the ventilation chamber 7 opened by the restricting tube 5 in the air delivery chamber 4, the cone head 13 is pressed, pushing the push rod 11 in the dust cover 9 to move toward the ventilation ring 8, the extension length of the spring 10 is shortened, and the cone head 13 is in contact with the ventilation ring 8. The ventilation chamber 7 is separated, and the air enters the air delivery chamber 4 through the ventilation chamber 7 and is transported to the observation box 3 through the air delivery chamber 4. When the air blowing is stopped, the cone head 13 loses pressure, the spring 10 gradually stretches, and pushes the push rod 11 Move toward one side of the exhalation nozzle 2, and block the ventilation chamber 7 through the cone 13, so that the breathed-in air remains inside the device.

In order to generate resistance, as shown in Figures 4 and 5, a chute 14 is provided inside the vent tube 12. The inside of the chute 14 is movably connected to the outside of the push rod 11. A breathable groove 15 is set up outside the vent tube 12. The breathable groove is 15 is internally connected with the ventilation chamber 7 .

When exhaling, the cone 13 is separated from the ventilation chamber 7. After the air enters the ventilation chamber 7 through the exhalation nozzle 2, it can enter the air delivery chamber 4 through the ventilation slot 15 on the ventilator 12. Therefore, when the valve 6 remains open, When the patient exhales, there is still a certain resistance.

In order to adjust the flow rate, as shown in Figures 1 and 3, a knob 16 is fixedly connected to the bottom of the valve 6, and a scale bar 17 is movably connected to one side of the knob 16. The knob 16 and the auxiliary scale 18 are adapted to each other, and the bottom of the scale bar 17 And an auxiliary scale 18 is fixedly installed on the top of the air cabin 1 .

When in use, turn the knob 16 clockwise, the valve 6 will deflect, so that the air delivery chamber 4 is unobstructed, and the scale bar 17 will extend. Observe that the value of the scale bar 17 on the secondary scale 18 corresponds to the deflection angle of the valve 6 connected to the knob 16. At the same time, because there is a certain friction between the knob 16 and the scale bar 17, when the air passes through the valve 6, the angle of the valve 6 is not easy to change.

In order to reduce the error, as shown in Figure 3, a chute 14 is provided inside the vent tube 12. The inside of the chute 14 is movably connected to the outside of the push rod 11. A ventilation groove 15 is provided on the outside of the vent tube 12. The ventilation groove 15 is internally connected with the ventilation chamber 7 .

When in use, due to the separation of the cone head 13 and the ventilation chamber 7, the exhalation nozzle 2, the observation box 3, the air delivery chamber 4, and the ventilation chamber 7 remain unobstructed. When the cone head 13 contacts the ventilation chamber 7, the ventilation chamber 7 is blocked, and the channel connecting the air delivery chamber 4 and the exhalation nozzle 2 is disconnected, causing the internal air to stop flowing.

Finally, in order to observe data, as shown in Figures 1 and 2, the main scale 19 is fixedly installed on the surface of the observation box 3, and a pressure chamber 20 and an indication chamber 21 are provided inside the observation box 3. The pressure chamber 20 and the indication chamber 21 are internally connected. , the observation box 3 is also equipped with a water injection port 23, the pressure chamber 20 and the indication chamber 21 are both equipped with partitions 22 inside, and the surface of the observation box 3 is also equipped with a pressure reduction port 24 and a water delivery port 25.

When in use, liquid is injected into the indicating chamber 21 through the water injection port 23, and the inhaled air enters the pressure chamber 20 through the air delivery chamber 4, so that the pressure in the indicating chamber 21 increases, forcing the liquid in the indicating chamber 21 to rise, and observe the liquid in the indicating chamber 21. Observe the position of the main scale 19 on the box 3 to obtain the amount of exhaled gas. When it is necessary to measure again, you can unplug the pressure reducing port 24 to release the air in the pressure chamber 20 and restore the pressure in the indication chamber 21. After use, Unplug the water delivery port 25 and release the liquid.

Certain exemplary embodiments of the present invention have been described above only by way of illustration. Needless to say, those of ordinary skill in the art can use various different embodiments without departing from the spirit and scope of the present invention. Modifications to the described embodiments are made. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
