[0030] Example 1: Figure 1-Figure 6As shown, an adjustable training device for lung recovery of patients undergoing cardiothoracic surgery includes a supporting base plate 1, a piston cylinder body 2, a piston block 3, a first spring 4, an exhaust solenoid valve 6, an air guide tube 7, a first non-return valve 8, an air guide hose 9, a cylindrical box body 10, an air suction pump 11, an air intake pipe 12, a second non-return valve 13, a limiting ring 14, an activated carbon plate 15 and an adjusting mechanism. The right part of the supporting base plate 1 is connected to the piston cylinder body 2, the piston cylinder body 2 is vertically arranged, the piston block 3 is slidingly and sealingly connected to the piston cylinder body 2, the piston block 3 can slide up and down in the piston cylinder body 2, a first spring 4 is connected between the bottom of the piston block 3 and the bottom of the piston cylinder body 2, a first air outlet 5 is opened at the bottom of the piston cylinder body 2, an exhaust solenoid valve 6 is installed on the upper rear side of the piston cylinder body 2, the exhaust solenoid valve 6 is located above the piston block 3, and the middle of the top of the piston cylinder body 2 An air guide rigid tube 7 is connected, a first one-way valve 8 is installed at the lower part of the air guide rigid tube 7, an air guide hose 9 is connected to the upper end of the air guide rigid tube 7, a detachable breathing nozzle is provided at the front end of the air guide hose 9, a cylindrical box 10 is connected to the left side of the top of the supporting base plate 1, the bottom of the cylindrical box 10 is open, an air suction pump 11 is installed in the middle part of the cylindrical box 10, an air intake pipe 12 is connected to the middle of the top of the cylindrical box 10, the air outlet end of the air suction pump 11 is connected to the lower end of the air intake pipe 12, the right end of the air intake pipe 12 is connected to the left side of the air guide rigid tube 7, a second one-way valve 13 is installed on the right part of the air intake pipe 12, two limit rings 14 are connected to the lower part of the cylindrical box 10, an activated carbon plate 15 is placed between the two limit rings 14, an inlet and outlet 16 is provided at the lower front part of the cylindrical box 10, and an adjusting mechanism for adjusting the opening degree of the first air outlet 5 is provided on the piston cylinder 2.

[0031] like Figure 6 As shown, the adjustment mechanism includes a mounting ring 171 and an adjustment block 172. The mounting ring 171 is connected to the bottom of the piston cylinder 2, and the adjustment block 172 is rotatably connected inside the mounting ring 171. The adjustment block 172 is provided with a second air outlet 173 with the same shape as the first air outlet 5.

[0032] like Figure 1 As shown, a breathing mask 30 is also included, and the air guide hose 9 is connected to the breathing mask 30.

[0033] like Figure 1 As shown, a placement rack 31 is also included. The placement rack 31 is connected to the right front side of the top of the support base plate 1. The top of the placement rack 31 has a placement groove for convenient placement of the air guide hose 9.

[0034] The nurse puts the breathing mask 30 on the patient's face, and the patient holds the breathing mouthpiece at the front end of the air guide hose 9. The breathing mouthpiece can be replaced to avoid cross infection, and then inhales. The suction pump 11 sucks the outside air into the air intake pipe 12, and the air flows into the air guide hard tube 7. Then the air will enter the patient's body through the air guide hose 9 to assist the patient in inhaling. The activated carbon plate 15 can filter the dust in the air and purify the air to prevent the dust from being inhaled into the air intake pipe 12 and causing the patient to feel uncomfortable. Then the patient exhales into the air guide hose 9, and the air flows into the air guide hard tube 7 through the air guide hose 9. Under the action of the second one-way valve 13, the air in the air guide hard tube 7 will not flow into the cylindrical box 10, so the air will flow into the piston cylinder 2, and the air pushes the piston block 3 to move downward. The first spring 4 is compressed, and the piston block 3 pushes the air in the piston cylinder 2. The air in the piston cylinder 2 is discharged through the first air outlet 5 and the second air outlet 173 to control the exhaust solenoid valve 6 is opened, and the air in the piston cylinder 2 is discharged through the exhaust solenoid valve 6. Under the action of the first spring 4, the piston block 3 moves upward and resets. Under the action of the first one-way valve 8, the air in the piston cylinder 2 will not flow into the air guide tube 7. This reciprocating process can be used to perform lung recovery training on the patient. The nurse can rotate the adjustment block 172 to adjust the overlap degree of the second air outlet 173 and the first air outlet 5, thereby adjusting the opening degree of the first air outlet 5. The greater the opening degree of the first air outlet 5, the higher the air outlet efficiency of the piston cylinder 2. Conversely, the lower the air outlet efficiency of the piston cylinder 2. If the patient recovers well, the opening degree of the first air outlet 5 can be appropriately reduced. Conversely, the opening degree of the first air outlet 5 can be appropriately increased. The training intensity can be adjusted according to the patient's recovery degree so as to adapt to patients in different situations. When training is not needed, the air guide hose 9 can be placed in the placement groove on the placement rack 31 to make the air guide hose 9 more tidy.

[0035] Embodiment 2: Based on embodiment 1, Figure 7 and Figure 8 As shown, it also includes a sealing shell 18, a sealing plate 19, a vertical guide rod 20, a sliding plate 21 and a second spring 22. The sealing shell 18 is connected to the top of the intake pipe 12, and the sealing plate 19 is slidably connected in the sealing shell 18. A through hole is opened at the top of the intake pipe 12, and the sealing plate 19 can be inserted into the intake pipe 12 through the through hole. A vertical guide rod 20 is connected to the left side of the top of the piston cylinder 2, and a sliding plate 21 is slidably connected on the vertical guide rod 20. The sliding plate 21 slides through the top of the piston cylinder 2, and the bottom of the sliding plate 21 contacts the top of the piston block 3. The top of the sliding plate 21 is connected to the bottom of the sealing plate 19. A second spring 22 is sleeved on the vertical guide rod 20, and the two ends of the second spring 22 are respectively connected to the vertical guide rod 20 and the sliding plate 21.

[0036] Initially, the second spring 22 is in a stretched state. When the piston block 3 moves downward, under the action of the second spring 22, the sliding plate 21 will move downward, and the sliding plate 21 drives the blocking plate 19 to move downward. The blocking plate 19 is inserted into the air intake pipe 12 through the through-hole and blocks the air intake pipe 12 to prevent the air in the air intake pipe 12 from flowing into the air guide tube 7, and prevents the newly inhaled air of the suction pump 11 from mixing with the gas exhaled by the patient, so as to maintain the independence of the gas flow direction, thereby avoiding the patient from feeling uncomfortable. When the piston block 3 moves upward, the piston block 3 pushes the sliding plate 21 to move upward, the second spring 22 is stretched, and the sliding plate 21 drives the blocking plate 19 to move upward, and the blocking plate 19 is moved out of the air intake pipe 12 to open the air intake pipe 12.

[0037] like Fig. 9 and Fig.10 As shown, it also includes a horizontal guide rod 23, an arc plate 24, a third spring 25 and a push-out frame 26. Two horizontal guide rods 23 are connected to the top of the support base plate 1. The two horizontal guide rods 23 are symmetrically arranged. The two horizontal guide rods 23 are slidably connected to the arc plate 24. The arc plate 24 is located in the inlet and outlet 16. The horizontal guide rods 23 are sleeved with a third spring 25. The two ends of the third spring 25 are respectively connected to the horizontal guide rod 23 and the arc plate 24. The rear side of the arc plate 24 is connected to the push-out frame 26, and the push-out frame 26 slides through the rear side of the cylindrical box 10.

[0038] like Fig.11 As shown, it also includes a guide connection block 27 and a blocking block 28. The lower front part of the cylindrical box body 10 is connected to the guide connection block 27, and the blocking block 28 is slidably connected to the guide connection block 27.

[0039] like Fig. 9 As shown, a placement plate 29 is also included, and the placement plate 29 is connected to the left front side of the top of the supporting base plate 1.

[0040] The blocking block 28 blocks the curved plate 24, and the third spring 25 is in a stretched state. When the activated carbon board 15 needs to be replaced, the nurse pulls the blocking block 28 upward so that the blocking block 28 no longer blocks the curved plate 24. Under the action of the third spring 25, the curved plate 24 moves forward, and the curved plate 24 drives the ejection rack 26 to move forward. The ejection rack 26 pushes the activated carbon board 15 forward, so that the activated carbon board 15 is removed from the inlet and outlet 16, and the activated carbon board 15 is moved to the placement plate 29, which is convenient for replacing the activated carbon board 15. Then the nurse The old activated carbon plate 15 is taken out from the placement plate 29, and the new activated carbon plate 15 is placed on the placement plate 29, and then the push-out rack 26 is pulled backward, the push-out rack 26 drives the arc plate 24 to move backward, the third spring 25 is stretched, the arc plate 24 pushes the new activated carbon plate 15 to move backward, and the new activated carbon plate 15 enters the cylindrical box 10 through the inlet and outlet 16, completing the replacement of the activated carbon plate 15, and releasing the blocking block 28, the blocking block 28 moves downward under the action of its own gravity, and the blocking block 28 blocks the arc plate 24 again.
