The patient sits on the medical chair or lies on the medical bed on the side, so that the lungs on the back of the patient are attached to the housing 2; during operation, the lungs on the back of the patient are attached to the housing 2, and the medical staff controls the output speed of the motor 4 through the control panel of the beater, drives the main shaft 3 to rotate at a constant speed, drives the plurality of knocking cams 5 to rotate, and knocks on the back of the patient. Since the plurality of knocking cams 5 are evenly distributed in a spiral shape at an angle of 120° around the main shaft 3, the knocking cams 5 knock on the patient's back sequentially from the waist upwards, which is beneficial for the patient to discharge pulmonary secretions; effectively reduces the workload of nurses, reduces the physical energy consumption of nurses, and improves the work efficiency of nurses.

[0034] As Figure 1 and Figure 2 shown, a robotic arm 6 is bolted to the middle of the side of the mounting beam 1 away from the housing 2; the robotic arm 6 in this embodiment is a six-axis robotic arm, and the robotic arm 6 is driven by six servo motors to rotate six axes, with higher flexibility, which can make the robotic arm 6 move within a nearly spherical working range, so as to facilitate the medical staff to adjust the position of the knocking unit to adapt to different usage environments and different patients; during operation, the robotic arm 6 is installed on the bottom of the medical chair or the medical bed through bolts, and the medical staff controls the robotic arm 6 through the control panel to attach the knocking unit to the back of the patient, so that the beater can adapt to different usage environments and different patients.

[0035] As Figures 1 to 3As shown, adjustment slots 7 are provided at both ends of the mounting beam 1. In the middle of the side of the housing 2 close to the mounting beam 1, a mountain-shaped block 8 is fixedly connected. Bent buckles are fixedly connected to both the top side and the bottom side of the mountain-shaped block 8. The middle protrusion of the mountain-shaped block 8 is in sliding fit with the inner wall of the adjustment slot 7. The inner wall of the mountain-shaped block 8 is in sliding fit with the outer wall of the mounting beam 1. A clamping block 9 is bolted to the middle protrusion of the mountain-shaped block 8. The outer wall of the clamping block 9 is in sliding fit with the side of the mounting beam 1 away from the mountain-shaped block 8. In this embodiment, the cross-section of the mountain-shaped block 8 is mountain-shaped, and bent buckles are provided on both the top side and the bottom side of the mountain-shaped block 8, so that the mountain-shaped block 8 is slidably fixed on the outside of the mounting beam 1. The clamping block 9 is bolted to the middle of the mountain-shaped block 8 to clamp and fix the mounting beam 1, so as to fixedly install the percussion unit at both ends of the mounting beam 1. During operation, according to the body width of the patient, the positions of the percussion units at both ends are adjusted to facilitate better percussion of the patient's lungs, thereby improving the applicable range of the beater.

[0036] As Figure 3 shown, scale marks 10 are provided on both sides of the side of the mounting beam 1 away from the housing 2. Calibration ports 11 are provided at the center positions of both the top side and the bottom side of the mountain-shaped block 8. The calibration ports 11 are aligned with the scale marks of the scale 10. During operation, when adjusting the position of the percussion unit, the mountain-shaped block 8 is pushed to slide along the mounting beam 1. Medical staff control the percussion units at both ends to maintain a symmetrical state through the cooperation of the calibration ports 11 and the scale 10, so as to facilitate the accurate adjustment by the medical staff.

[0037] As Figures 4 to 6 shown, a silica gel ring 12 is fixedly connected to the outer ring of the opening of the housing 2. A ring groove 13 is provided in the middle of the side of the silica gel ring 12 away from the housing 2. A ring cavity 14 is provided inside the silica gel ring 12. During operation, when the patient's back leans against the opening of the housing 2, the patient's back presses against the silica gel ring 12, causing the ring cavity 14 inside the silica gel ring 12 to be compressed, reducing the impact force of the housing 2 on the patient's back and reducing the harm to the patient's back. At the same time, the side wall of the ring groove 13 of the silica gel ring 12 bends outward to generate negative pressure in cooperation with the patient's back, causing the housing 2 to adsorb on the patient's back and reducing the probability of the patient's back detaching from the housing 2.

[0038] As Figures 4 to 6 shown, a silica gel sheet 15 is fixedly connected to the inner ring of the silica gel ring 12. The outer ring of the percussion cam 5 is in sliding fit with the outer wall of the silica gel sheet 15. By providing the silica gel sheet 15, the percussion cam 5 is isolated, reducing the direct impact of the percussion cam 5 on the patient's back and reducing the harm to the patient's back.

[0039] As Figures 4 to 6As shown, chutes 16 are provided at both ends of the housing 2. Sliders 17 are slidably installed inside the chutes 16. Both ends of the main shaft 3 rotatably penetrate through the sliders 17 on both sides. The motor 4 is fixedly connected to the slider 17 on one side. A screw rod 18 is rotatably installed at the top of the slider 17. The screw rod 18 rotatably penetrates through the outer wall of the housing 2, and the screw rod 18 is in threaded cooperation with the housing 2. A locking nut 19 is threadedly installed at one end of the screw rod 18 away from the slider 17. During operation, according to the obesity degree and the bearing strength of the patient's back, the percussion force of the percussion cam 5 on the patient's back is controlled. When the patient is relatively obese and can withstand a higher force, rotate the screw rod 18 to push the slider 17 to slide downward along the chute 16, push the main shaft 3 to slide towards the opening of the housing 2, drive the percussion cam 5 to move towards the opening of the housing 2, and rotate the locking nut 19 along the screw rod 18 so that the locking nut 19 contacts the outer wall of the housing 2 to fix the screw rod 18, reducing the probability of displacement of the slider 17, thereby increasing the percussion degree of the percussion cam 5 on the patient's back. When the patient is relatively thin and can withstand a lower force, rotate the screw rod 18 to drive the slider 17 to slide upward along the chute 16, drive the main shaft 3 to slide towards the inside of the housing 2, drive the percussion cam 5 to move towards the inside of the housing 2, and rotate the locking nut 19 along the screw rod 18 so that the locking nut 19 contacts the outer wall of the housing 2 to fix the screw rod 18, reducing the probability of displacement of the slider 17, thereby reducing the percussion degree of the percussion cam 5 on the patient's back.

[0040] As Figures 7 to 8 shown, a groove 20 is provided on the side of the percussion cam 5 away from the main shaft 3. An air cushion 21 is fixedly connected inside the groove 20. Through the elasticity and buffering of the air cushion 21, the direct impact of the percussion cam 5 on the patient's back is reduced, reducing the harm to the patient's back. At the same time, the comfort level of the patient is improved.

[0041] As Figures 7 to 8As shown, a slide bar 22 is fixedly connected to the middle of the percussion cam 5. A supplementary airbag 23 is fixedly connected to the middle of the percussion cam 5 near the bottom surface of the groove 20. The inner ring of the supplementary airbag 23 is sleeved on the outer ring of the slide bar 22. A counterweight 24 is slidably mounted on the outer ring of the slide bar 22. A plurality of air pipes 25 are connected between the supplementary airbag 23 and the air cushion 21, and the air pipes 25 penetrate through the outer wall of the percussion cam 5. During operation, when the percussion cam 5 rotates, under the action of gravity and centrifugal force, the counterweight 24 slides along the slide bar 22, so that the counterweight 24 impacts the supplementary airbag 23, and the gas inside the supplementary airbag 23 is flushed into the air cushion 21 through the air pipes 25, causing the air cushion 21 to expand. After the air cushion 21 impacts the patient's back along with the percussion cam 5, the air cushion 21 compresses and absorbs shock, and the gas inside the air cushion 21 is discharged back into the supplementary airbag 23, causing the supplementary airbag 23 to expand and push out the counterweight 24. After the counterweight 24 slides out, it slides back again under the action of gravity and centrifugal force to impact the supplementary airbag 23, improving the protection of the patient's back and the comfort of the patient.

[0042] Embodiment 2

[0043] As Figure 9 shown, compared with Embodiment 1, another implementation manner of the present invention is as follows: A fixing seat 26 is bolted to the middle of the side of the mounting beam 1 close to the housing 2. A hollow cushion 27 is fixedly connected to the middle of the fixing seat 26. The hollow cushion 27 is made of silica gel. An air pump is arranged on the side of the fixing seat 26 away from the hollow cushion 27, and the air pump is communicated with the hollow cushion 27. During operation, when the lungs of the patient's back are attached to the housing 2, the spine of the patient is attached to the hollow cushion 27. By adjusting the gas inside the hollow cushion 27 through the air pump, the hollow cushion 27 deforms as the patient's back changes, and the hollow cushion 27 wraps the patient's back, improving the protection of the patient's spine and the comfort of the patient.

[0044] Working principle: The patient sits on a medical chair or lies on a medical bed on the side. The medical staff uses a tape measure to measure the width of the patient's back. According to the body width of the patient, adjust the positions of the percussion units at both ends, push the mountain-shaped block 8 to move along the adjustment groove 7. At the same time, observe the scale 10 through the calibration port 11. After moving the mountain-shaped block 8 to a suitable position, lock the clamping block 9 with a bolt to clamp and fix the mounting beam 1, and fixedly install the percussion units at both ends of the mounting beam 1.

[0045] The tapping force of the tapping cam 5 on the patient's back is controlled according to the degree of obesity and the degree of force the patient's back can withstand. When the patient is obese and can withstand a higher force, the screw 18 is rotated to push the slider 17 to slide downward along the slide groove 16, and the main shaft 3 is pushed toward the opening of the shell 2, driving the tapping cam 5 to move toward the opening of the shell 2, and the locking nut 19 is rotated along the screw 18 so that the locking nut 19 contacts the outer wall of the shell 2, fixing the screw 18, reducing the probability of displacement of the slider 17, thereby increasing the tapping degree of the tapping cam 5 on the patient's back; when the patient is thin and can withstand a lower force, the screw 18 is rotated to drive the slider 17 to slide upward along the slide groove 16, driving the main shaft 3 to slide toward the inside of the shell 2, driving the tapping cam 5 to move toward the inside of the shell 2, and rotating the locking nut 19 along the screw 18 so that the locking nut 19 contacts the outer wall of the shell 2, fixing the screw 18, reducing the probability of displacement of the slider 17, thereby reducing the tapping degree of the tapping cam 5 on the patient's back;

[0046] Medical personnel control the robotic arm 6 through the control panel to fit the shell 2 to the patient's back. The patient's back presses against the silicone ring 12, compressing the annular cavity 14 inside the silicone ring 12, reducing the impact force of the shell 2 on the patient's back and reducing damage to the patient's back. At the same time, the side wall of the annular groove 13 of the silicone ring 12 bends outward, generating negative pressure on the patient's back, so that the shell 2 is adsorbed on the patient's back, reducing the probability of the patient's back detaching from the shell 2.

[0047] Medical personnel control the output speed of the motor 4 through the control panel of the flapper, drive the main shaft 3 to rotate at a constant speed, drive the multiple tapping cams 5 to rotate, and tap the patient's back. When the tapping cam 5 rotates, the counterweight 24 slides along the slide bar 22 under the action of gravity and centrifugal force, causing the counterweight 24 to impact the supplementary air bag 23, and the gas inside the supplementary air bag 23 is rushed into the interior of the air cushion 21 through the trachea 25, causing the air cushion 21 to expand. After the air cushion 21 is hit on the patient's back along with the tapping cam 5, the air cushion 21 is Compression shock absorption causes the gas inside the air cushion 21 to be discharged back into the interior of the supplementary air bag 23, causing the supplementary air bag 23 to expand and push out the counterweight 24; after the counterweight 24 slides out, it slides back again under the action of gravity and centrifugal force to impact the supplementary air bag 23; since the multiple tapping cams 5 are evenly distributed in a spiral shape at an angle of 120° around the main axis 3, the tapping cams 5 tap in sequence from the patient's waist upwards, which is beneficial for the patient to discharge lung secretions; it effectively reduces the workload of nurses, reduces the physical energy consumption of nurses, and improves the work efficiency of nurses.
