[0026] In the above embodiment, it should be noted that the counting scale 110 contains numbers from 0 to 60, and a maximum of 60 times can be recorded. The first spring 50 plays an elastic pulling role, which can increase the resistance of the piston plate 40 when it moves, thereby improving the breathing exercise effect;

[0027] The technical effect achieved by the above embodiment is: by blowing air into the long tube 10, the piston plate 40 will be pushed by the gas, which can have a good exercise effect on the patient's heart, chest and breathing, thereby playing a nursing role.

[0028] Example 2

[0029] like Figures 1 to 6 As shown, a cardiothoracic surgical respiratory exercise nursing device includes all the contents of Example 1, wherein the driving pointer 80 includes a ratchet 801, the front of the ratchet 801 is fixedly connected to a first bevel gear 802, the other end of the first bevel gear 802 is meshedly connected to a second bevel gear 803, one end of the circular groove 100 is rotatably connected to a pointer 804, the pointer 804 is fixedly connected to the shaft of the second bevel gear 803, the bottom end of the ratchet 801 is meshedly connected to a braking pawl 805, one side of the braking pawl 805 is affixed to a leaf spring 806, and the first circular cover 60 is provided with a plurality of protruding teeth. A rocker 807 is movably connected to the rear interior, and a driving pawl 808 is movably connected to the front of the rocker 807. The driving pawl 808 is meshed with the ratchet 801. A second spring 809 is fixedly connected between the rocker 807 and the first round cover 60. The front of the first bevel gear 802 is rotatably connected to the front inner wall of the cylinder 70. The front of the braking pawl 805 is rotatably connected to the front inner wall of the cylinder 70. The bottom end of the leaf spring 806 is fixedly connected to the support rod 120. The front end of the support rod 120 is fixedly connected to the front inner wall of the cylinder 70.

[0030] In the above embodiment, it should be noted that the pointer 804 is used in conjunction with the counting scale 110, and the push rod 90 is aligned with the rocker 807, so that when the push rod 90 moves to a suitable position, it can push the rocker 807 to swing;

[0031] The technical effect achieved by the above embodiment is: it has an automatic counting function, so that the patient can easily grasp the number of exercises, and there is no need for power supply, so there is no need to worry about insufficient power.

[0032] Example 3

[0033] like Figures 1 to 6 As shown, a cardiothoracic surgical respiratory exercise nursing device includes all the contents of Example 2. In addition, ventilation holes 130 are opened at the upper and lower ends of the long tube 10, and the piston piece 40 will not pass through the ventilation holes 130;

[0034] In the above embodiment, it should be noted that since the air hole 130 is close to the first round cover 60 and the inner wall of the long tube 10 is integrally connected with a retaining ring, the piston plate 40 will not pass through the air hole 130 and will not interfere with the patient's breathing exercise.

[0035] The technical effect achieved by the above embodiment is: good ventilation effect.

[0036] Example 4

[0037] like Figures 1 to 6 As shown, a cardiothoracic surgical respiratory exercise nursing device includes all the contents of Example 3. In addition, an exhalation exercise blowing nozzle 20 for cardiothoracic surgery includes a second circular cover 21 threadedly connected to one end of the long tube 10, one end of the second circular cover 21 is fixedly connected to an air outlet 22, one end of the second circular cover 21 is rotatably connected to three circumferentially distributed knobs 23, the other end of the second circular cover 21 is rotatably connected to two movable pieces 24, the movable pieces 24 are fixedly connected to the axis of the knob 23, the other end of the second circular cover 21 is fixedly connected to three circumferentially distributed first magnet strips 25 and second magnets 26, the movable pieces 24 are made of magnet material, the second circular cover 21 is made of plastic material, and the outer surface of the air outlet 22 is wrapped with a rubber sleeve;

[0038] In the above embodiment, it should be noted that when the movable sheet 24 is magnetically attached to the first magnet 25, the movable sheet 24 blocks the air outlet 22, and when the movable sheet 24 is magnetically attached to the second magnet sheet 26, the movable sheet 24 is staggered from the air outlet 22.

[0039] The technical effect achieved by the above embodiment is: rotating the knob 23 can drive the movable piece 24 to swing, and by controlling the amount of the air outlet 22 blocked by the movable piece 24, the size of the air outlet 22 can be adjusted, thereby adjusting the resistance to air blowing to meet the actual different needs of patients. The setting of the rubber sleeve can increase the softness of the outer surface of the air outlet 22, making it comfortable to use.

[0040] Working principle: put the air blowing port 22 into the mouth of a patient in cardiothoracic surgery and blow air. At this time, gas enters the long cylinder 10, and the piston plate 40 is pushed by the gas to move. The first spring 50 is elastically stretched, and the push rod 90 moves accordingly. After moving to an appropriate position, the push rod 90 will push the rocker 807 to swing. At this time, the rocker 807 drives the ratchet 801 to rotate slightly by driving the pawl 808, and the ratchet 801 drives the first bevel gear 802 to rotate, and the first bevel gear 802 drives the second bevel gear 803 to rotate, and the second bevel gear 803 drives the pointer 804 to rotate. Release the air blowing port 22. Under the elastic force of the first spring 50, the piston plate 40 loses the push of the gas and automatically resets. The push rod 90 separates from the rocker 807, and the braking pawl 805 cooperates with the leaf spring 806 to limit the rotation of the ratchet 801, so that the pointer 804 can rotate one grid stably, thereby having the function of automatic counting.
