Detailed implementation manners

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] The present invention will be further described below in conjunction with embodiments.

[0036] The "left", "right", "front", "rear", "upper", and "lower" mentioned in the following description are oriented in the viewing direction of the front view.

[0037] Example 1: In some embodiments, refer to Figures 1 - 10 , a pulmonary rehabilitation training device, including a main bracket 1, and further including: an adjustable blowing device 2, a clamping device 3, a leg exercise device 4, and a hand exercise device 5. The main bracket 1 is fixedly installed on the bed frame. The adjustable blowing device 2 is installed on the main bracket 1. The clamping device 3 is arranged on the left side of the main bracket 1. Two leg exercise devices 4 are installed on the clamping device 3. The hand exercise device 5 is installed on the leg exercise device 4. The adjustable blowing device 2 includes: an air pipe 21, a piston 22, a push rod 23, a spring 24, and a hose 25. The air pipe 21 is fixedly installed on the upper side of the main bracket 1. The piston 22 is slidably connected inside the air pipe 21. The lower side of the push rod 23 is fixedly installed on the upper side of the piston 22. The upper side of the push rod 23 is slidably connected to the upper side of the air pipe 21. The spring 24 is arranged on the push rod 23. The upper side of the spring 24 is closely attached to the air pipe 21. The lower side of the spring 24 is closely attached to the piston 22. One end of the hose 25 is fixedly connected to the lower side of the air pipe 21. The adjustable blowing device 2 further includes: a reminder mechanism, and the reminder mechanism is installed on the upper side of the air pipe 21.

[0038] As Figure 1 , Figure 2 , Figure 3 shown, the adjustable blowing device 2 can adjust the blowing force according to the different conditions of different patients, which helps to adapt to the lung exercises of different patients. The clamping device 3 is used to clamp the bed frame, so that the device can be quickly fixed on the bed frame, and the device can be adjusted left and right without unlocking the device from the bed frame, so that the device can adapt to the patient, which helps for patients who are bedridden for a long time. After the device is fixed, there is no need to repeatedly adjust the patient's position, which helps the patient to use it comfortably. The leg exercise device 4 can be adjusted according to the leg spacing when the patient's legs move. The hand exercise device 5 can perform multi-angle exercises and drive the leg exercise device 4 to move at the same time.

[0039] As Figure 1 , Figure 4 , Figure 5 shown, the hose 25 of the adjustable blowing device 2 is inserted into the patient's mouth. The patient blows air through the hose 25 into the air pipe 21, so that the piston 22 moves upward. The upward movement of the piston 22 drives the push rod 23 to move upward, so that the spring 24 undergoes elastic deformation. The push rod 23 contacts the reminder mechanism, and the reminder mechanism is triggered to remind the patient that the blowing this time has reached the training volume. The elastic deformed spring 24 restores to push the push rod 23 back to the initial position. The push rod 23 returns to the initial position to drive the piston 22 back to the initial position, waiting for the patient's next blow to trigger.

[0040] The reminder mechanism includes: an upper side frame 26, a cross bar 27, a first adjusting screw 28, and a bell 29. The upper side frame 26 is fixedly installed on the upper side of the ventilation pipe 21. The cross bar 27 is arranged inside the upper side frame 26. A plurality of first strip-shaped openings 210 are formed in the upper side frame 26. The first adjusting screw 28 passes through the first strip-shaped opening 210 and is threadedly connected to the cross bar 27. The bell 29 is connected to the middle side of the cross bar 27 through a knot.

[0041] Loosen the first adjusting screws 28 at both ends of the cross bar 27 of the reminder mechanism, move the cross bar 27 up and down to a suitable position, and tighten the first adjusting screws 28 to fix the cross bar 27. The ejector rod 23 moves upward and touches the bell 29, and the bell 29 makes a sound to remind the patient that the blowing volume has reached the training volume this time. By adjusting the height of the bell 29, the effect of adjusting the blowing force can be achieved, which is beneficial to meeting the lung exercise requirements of different patients.

[0042] Embodiment 2: In some embodiments, as Figures 1 - 10 shown, as a preferred embodiment of the present invention, the clamping device 3 includes: a sub-bracket 31, a first threaded rod 32, and a rotating block 33. The two sub-brackets 31 are symmetrically arranged front and back on the bed frame. Two first grooves 34 are formed in the lower side of the sub-bracket 31. Two first threaded rods 32 are hinged in the first groove 34 of the rear sub-bracket 31. One end of the first threaded rod 32 away from the rear sub-bracket 31 is arranged in the first groove 34 of the front sub-bracket 31. The rotating block 33 is threadedly connected to the front side of the first threaded rod 32. The rotating block 33 is located on the front side wall of the front sub-bracket 31.

[0043] As Figure 9 、 Figure 10 shown, the sub-brackets 31 of the clamping device 3 are placed on both sides of the bed frame. Rotate the first threaded rod 32 into the first groove 34 of the sub-bracket 31, and tighten the rotating block 33. The rotating block 33 presses against the sub-bracket 31 to lock the first threaded rod 32, which is beneficial to quickly locking the two sub-brackets 31.

[0044] The clamping device 3 further includes: a lifting mechanism. The lifting mechanism is installed at both the left and right ends of each sub-bracket 31. The lifting mechanism includes: a special-shaped sliding block 35, a guide wheel 36, and a second threaded rod 37. The two special-shaped sliding blocks 35 are slidably connected to the sub-bracket 31. The guide wheel 36 is rotatably connected to one end of the special-shaped sliding block 35 close to the bed frame through a rotating shaft. The second threaded rod 37 is threadedly connected to one end of the special-shaped sliding block 35 away from the bed frame.

[0045] The lifting mechanism further includes: a synchronization component, which is installed on the auxiliary bracket 31. The synchronization component includes: a gear 38 and a knob 39. The two gears 38 are rotatably connected to the auxiliary bracket 31 through a rotating shaft. The gears 38 and the second threaded rod 37 are in one-to-one correspondence. One end of the second threaded rod 37 away from the special-shaped sliding block 35 is fixedly connected to the rotating shaft of the gear 38. The two gears 38 are meshed with each other. The knob 39 is fixedly installed on the rotating shaft of one of the gears 38.

[0046] When the knob 39 of the synchronization component of the lifting mechanism rotates, it drives the gear 38 to rotate. The rotation of the gear 38 drives the second threaded rod 37 to rotate. The rotation of the second threaded rod 37 causes the special-shaped sliding block 35 to move on the auxiliary bracket 31. The special-shaped sliding block 35 moves towards the bed frame. The movement of the special-shaped sliding block 35 towards the bed frame drives the guide wheel 36 to move towards the bed frame, causing the auxiliary bracket 31 to leave the bed frame. At this time, multiple guide wheels 36 support between the auxiliary bracket 31 and the bed frame. Move the auxiliary bracket 31 left and right to a suitable position, and rotate the knob 39 to move the special-shaped sliding block 35 and the guide wheel 36 to the initial position, which is beneficial to adjusting the left and right orientation of the clamping device 3 in the clamping state and avoiding repeatedly moving the patient's position to adapt to the device after the patient lies down.

[0047] Embodiment 3: In some embodiments, as Figures 1 - 10 shown, as a preferred embodiment of the present invention, the leg exercise device 4 includes: a leg support plate 41, a sliding plate 42 and a second adjusting screw 43. The leg support plate 41 is fixedly installed on the auxiliary bracket 31. The sliding plate 42 is slidably connected to the leg support plate 41. Second strip-shaped openings 44 are provided on both the left and right sides of the leg support plate 41. The second adjusting screw 43 passes through the second strip-shaped opening 44 and is threadedly connected to the sliding plate 42.

[0048] As Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 shown, loosen the second adjusting screw 43 of the leg exercise device 4, move the sliding plate 42 back and forth to a suitable position, and tighten the second adjusting screw 43 to fix the sliding plate 42 on the leg support plate 41, which is beneficial to adjusting the sliding plate 42 to adapt to the leg spacing between the legs of different patients.

[0049] The leg exercise device 4 further includes: a first rotating plate 45, a second rotating plate 46, a vertical plate 47, a special-shaped support block 48, and a first tension spring 49. The left side of the first rotating plate 45 is slidably connected to the left side of the sliding plate 42. The right side of the second rotating plate 46 is hinged to the right side of the sliding plate 42. The left side of the second rotating plate 46 is hinged to the right side of the first rotating plate 45. The vertical plate 47 is fixedly installed on the left side of the first rotating plate 45. The special-shaped support block 48 is fixedly installed in the middle of the sliding plate 42. The lower right side of the first rotating plate 45 is in close contact with the upper left side of the special-shaped support block 48. The lower left side of the second rotating plate 46 is in close contact with the upper right side of the special-shaped support block 48. One end of the first tension spring 49 is fixedly connected to the right side of the first rotating plate 45, and the other end of the first tension spring 49 is fixedly connected to the sliding plate 42.

[0050] When the first rotating plate 45 moves to the right, it drives the second rotating plate 46 to rotate. At the same time, the first rotating plate 45 rotates, so that the first rotating plate 45 and the second rotating plate 46 form an inverted V shape. The first tension spring 49 undergoes elastic deformation. The first rotating plate 45 and the second rotating plate 46 form an inverted V shape to support the patient's leg, so as to achieve the effect of leg movement. The first tension spring 49 that has undergone elastic deformation restores to pull the first rotating plate 45 and the second rotating plate 46 back to the initial position, which is beneficial to supporting the patient's leg for movement.

[0051] The leg exercise device 4 further includes: an elastic mechanism. Elastic mechanisms are installed on both the left and right sides of each leg support plate 41. The elastic mechanism includes: a fixed plate 410, a connecting rod 411, and a second tension spring 412. The fixed plate 410 is fixedly installed on both the left and right sides of the leg support plate 41. The connecting rod 411 is slidably connected to the fixed plate 410. One end of the second tension spring 412 is fixedly connected to the connecting rod 411, and the other end of the second tension spring 412 is fixedly connected to the fixed plate 410. The connecting rods 411 of adjacent elastic mechanisms are fixedly connected to each other.

[0052] The auxiliary bracket 31 of the clamping device 3 moves back and forth to adapt to bed frames of different widths. The back-and-forth movement of the auxiliary bracket 31 drives the fixed plate 410 of the elastic mechanism to move back and forth, so that the connecting rod 411 between the fixed plates 410 moves back and forth. The second tension spring 412 undergoes elastic deformation to provide a clamping force for the upper side of the auxiliary bracket 31 to clamp on the bed frame. The lower side of the auxiliary bracket 31 provides a clamping force through the first threaded rod 32 and the rotating block 33.

[0053] Such as Figure 8As shown, the hand exercise device 5 includes: a fixed pulley 51, a guide rod 52, and a connecting rope 53. The fixed pulley 51 is rotatably connected to the right side of the sliding plate 42 through a rotating shaft. The guide rod 52 is rotatably connected to the right side of the sliding plate 42 through a rotating shaft. The guide rod 52 is located on the left side of the fixed pulley 51. A second groove 54 is formed in the middle of the sliding plate 42. The left side of the connecting rope 53 is fixedly connected to the left side of the first rotating plate 45. The middle side of the connecting rope 53 is arranged in the second groove 54. The right side of the connecting rope 53 passes through the fixed pulley 51.

[0054] The hand exercise device 5 further includes: a support bracket 55, a movable pulley 56, a third adjustment screw 57, and a pull plate 58. Two support brackets 55 are slidably connected to the right side of each leg support plate 41. The movable pulley 56 is hinged to the support bracket 55. A plurality of third strip-shaped openings 59 are formed in the right side of the leg support plate 41. The two third adjustment screws 57 pass through the third strip-shaped openings 59 and are threadedly connected to the support bracket 55. The pull plate 58 is arranged on the right side of the leg support plate 41. The right side of the connecting rope 53 passes through the fixed pulley 51 and then passes through the two movable pulleys 56 and is fixedly connected to the left side of the pull plate 58.

[0055] Loosen the third adjustment screw 57 of the hand exercise device 5, move the support bracket 55 back and forth. The forward and backward movement of the support bracket 55 drives the movable pulley 56 to move back and forth. The forward and backward movement of the movable pulley 56 drives the connecting rope 53 to extend or shorten, so as to adjust the length of the connecting rope 53. Tighten the third adjustment screw 57 to fix the support bracket 55, which is beneficial to quickly adjust the length of the connecting rope 53 to adapt to the arm lengths of different patients.

[0056] At the same time, through the pull plate 58 and the connecting rope 53, the range of hand movement is not restricted, and the hand can be stretched or bent at multiple angles during hand exercise.

[0057] The patient holds the pull plate 58 with both hands and pulls. The movement of the pull plate 58 away from the leg support plate 41 drives the connecting rope 53 to move to the right. Guided by the movable pulley 56 and the fixed pulley 51, the rightward movement of the connecting rope 53 drives the first rotating plate 45 to move to the right. The rightward movement of the first rotating plate 45 drives the second rotating plate 46 to rotate. At the same time, the first rotating plate 45 rotates, so that the first rotating plate 45 and the second rotating plate 46 form an inverted V shape. The first tension spring 49 undergoes elastic deformation. The formation of an inverted V shape by the first rotating plate 45 and the second rotating plate 46 supports the patient's legs, so as to achieve the effect of leg movement. The elastic deformation of the first tension spring 49 is restored to pull the first rotating plate 45 and the second rotating plate 46 back to the initial position, which is beneficial to supporting the patient's legs for movement.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
