Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an auxiliary device for passive cardiopulmonary rehabilitation training. Background Technology

[0002] Cardiopulmonary rehabilitation refers to the process of restoring cardiopulmonary function through a series of rehabilitation training programs targeting the cardiopulmonary system. Cardiopulmonary rehabilitation is suitable for patients with cardiopulmonary diseases, post-operative rehabilitation, and athletes. Training methods include aerobic exercise, strength training, and flexibility training. Aerobic exercise refers to prolonged exercise at low to moderate intensity, such as walking, jogging, and swimming. This type of training can improve the endurance and function of the cardiopulmonary system, lower heart rate and blood pressure, and reduce the incidence of cardiopulmonary diseases. Strength training can enhance muscle strength, improve physical function, and prevent the occurrence of cardiopulmonary diseases. Flexibility training can increase body flexibility, improve coordination and balance, and reduce the occurrence of sports injuries. Currently, some middle-aged and elderly patients, due to poor physical condition, generally find it difficult to undergo active cardiopulmonary rehabilitation training. They usually require caregivers to lead them in chest expansion exercises, passively assisting with rehabilitation training. However, this method is very time-consuming and energy-intensive for caregivers, and prolonged training can easily lead to fatigue, resulting in poorer rehabilitation effects. Summary of the Invention

[0003] To address the shortcomings of existing methods, this invention provides an auxiliary device for passive cardiopulmonary rehabilitation training. This device solves the problems that passively assisting patients with rehabilitation training is very time-consuming and energy-intensive for nursing staff, and that prolonged training can easily lead to fatigue among nursing staff, resulting in a decrease in the effectiveness of rehabilitation training.

[0004] To solve the above problems, the present invention provides the following technical solution: an auxiliary device for passive cardiopulmonary function rehabilitation training, comprising a base, a first telescopic rod fixedly connected to the middle of the upper surface of the base, a first mattress fixedly connected to the top of the first telescopic rod, a stabilizing device fixedly connected to the lower surface of the first mattress, the bottom of the stabilizing device fixedly connected to the upper surface of the base, the stabilizing devices being symmetrically arranged on both sides of the first telescopic rod, a second mattress rotatably connected to the side of the outer surface of the first mattress, a training device fixedly connected to the side of the outer surface of the second mattress, a support device being provided at the bottom of the second mattress, a connecting screw rotatably connected to the side of the first mattress away from the second mattress, a third mattress fixedly connected to the outer surface of the connecting screw, the outer surface of the connecting screw penetrating the first mattress, an adjusting turntable fixedly connected to the output end of the connecting screw, a through hole being provided inside the adjusting turntable, the through holes being arranged in a ring along the outer surface of the adjusting turntable, a limiting rod being inserted into the through hole, the outer surface of the limiting rod being pressed and fitted with a groove on the outer surface of the first mattress.

[0005] The working principle of the above technical solution is as follows:

[0006] During use, the patient lies flat on the first, second, and third mattresses, holding the training device with both hands. Activating the device encourages the patient to perform chest-expanding exercises, enhancing cardiopulmonary function and promoting recovery. The drive mechanism then lifts the second mattress upwards until it is vertical. The limiting rod is then removed, and the adjustment dial is rotated to lower the third mattress to a vertical position. The limiting rod is then inserted into the through-hole aligned with the groove on the first mattress, fixing the adjustment dial in its current position and maintaining the third mattress in its current state. The patient sits on the first mattress, and the first telescopic rod is remotely extended or retracted according to their height and leg length, allowing their feet to contact the ground for support. Simultaneously, the stabilizing device extends or retracts, providing support to the first mattress and preventing damage after prolonged use. The patient, sitting on the first mattress with their back against the vertical second mattress and holding the training device with both hands, performs chest-expanding exercises in a seated position. This increases the device's flexibility, allowing the patient to choose between lying or seated positions based on their individual comfort level.

[0007] Preferably, the stabilizing device includes a first connector, the bottom of which is fixedly connected to the upper surface of the base, a rotating sleeve is rotatably connected inside the first connector, and a connecting rod is slidably connected to the inner surface of the rotating sleeve.

[0008] The connecting rod provides support for the first mattress and distributes the pressure on the first telescopic rod, thereby improving the stability of the device and preventing the first telescopic rod from suffering excessive wear.

[0009] Preferably, the outer surface of the connecting rod penetrates the rotating sleeve and extends to the outside, the output end of the connecting rod is rotatably connected to a fixing member, the outer surface of the fixing member is fixedly connected to the lower surface of the first mattress, the end of the connecting rod away from the fixing member is fixedly connected to a telescopic spring, and the end of the telescopic spring away from the connecting rod is fixedly connected to the bottom of the inner surface of the rotating sleeve.

[0010] With the included telescopic spring, the elasticity of the spring provides cushioning during the lifting and lowering of the first mattress, further extending the service life of the first telescopic rod.

[0011] Preferably, the training device includes a fixed frame, the outer surface of which is fixedly connected to the side of the outer surface of the second mattress, a forward and reverse motor is fixedly connected to the top of the fixed frame, a worm gear is fixedly connected to the output end of the forward and reverse motor, and a connecting rod is rotatably connected to the outer surface of the fixed frame.

[0012] The worm gear is equipped with two worm wheels that mesh with it, causing the worm wheels to rotate and drive the two bent rods to rotate, making it easier for the patient to perform chest expansion exercises.

[0013] Preferably, a worm gear is fixedly connected to the outer surface of the connecting rod, the connecting rod and the worm gear are symmetrically arranged on both sides of the worm, the outer surface of the worm gear meshes with the outer surface of the worm, a bent rod is fixedly connected to the output end of the connecting rod, and a second telescopic rod is fixedly connected to the outer surface of the bent rod.

[0014] The second telescopic rod can be remotely driven to extend or retract according to the patient's needs, making it easier for the patient to prepare for appropriate chest expansion exercises. It can also be adjusted appropriately for different patients.

[0015] Preferably, a rubber sleeve is fixedly connected to the output end of the second telescopic rod, a fixed grip is fixedly connected to the inner surface of the rubber sleeve, and an infrared sensor is fixedly connected to the inner surface of the rubber sleeve.

[0016] With the addition of infrared sensors, when the patient's hands are removed from the rubber sleeves, the infrared sensors transmit signals to the forward and reverse motors, causing them to stop running, thus improving safety during the training process.

[0017] Preferably, the support device includes an internal groove, which is formed on the lower surface of the second mattress. A stepper motor is fixedly connected to the inner surface of the internal groove. A screw is fixedly connected to the output end of the stepper motor. A slider is threadedly connected to the outer surface of the screw. A second connector is fixedly connected to the outer surface of the slider.

[0018] The stepper motor is activated to rotate the screw, and the slider moves along the outer surface of the screw, thus providing a driving function.

[0019] Preferably, a third telescopic rod is rotatably connected inside the second connector, and a support rod is rotatably connected to the end of the third telescopic rod away from the second connector. A vacuum suction cup is fixedly connected to the bottom end of the support rod.

[0020] The vacuum suction cups ensure that the entire support device remains firmly attached to the ground, and the suction force of the vacuum suction cups improves the stability of the device.

[0021] This invention provides an auxiliary device for passive cardiopulmonary rehabilitation training. It has the following beneficial effects:

[0022] I. This passive cardiopulmonary rehabilitation training auxiliary device, through the first telescopic rod and stabilizing device, improves the stability of the device while avoiding excessive wear on the first telescopic rod, thus extending its service life.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0034] Example 1:

[0035] like Figures 1-7As shown, an auxiliary device for passive cardiopulmonary rehabilitation training includes a base 1. A first telescopic rod 2 is fixedly connected to the middle of the upper surface of the base 1. A first mattress 3 is fixedly connected to the top of the first telescopic rod 2. A stabilizing device 4 is fixedly connected to the lower surface of the first mattress 3. The bottom of the stabilizing device 4 is fixedly connected to the upper surface of the base 1. The stabilizing devices 4 are symmetrically arranged on both sides of the first telescopic rod 2. A second mattress 5 is rotatably connected to the side of the outer surface of the first mattress 3. A training device 6 is fixedly connected to the side of the outer surface of the second mattress 5. A support device 7 is provided at the bottom of the mattress 5. A connecting screw 8 is rotatably connected to the side of the first mattress 3 away from the second mattress 5. A third mattress 9 is fixedly connected to the outer surface of the connecting screw 8. The outer surface of the connecting screw 8 penetrates the first mattress 3. An adjusting turntable 10 is fixedly connected to the output end of the connecting screw 8. A through hole 11 is opened inside the adjusting turntable 10. The through holes 11 are arranged in a ring along the outer surface of the adjusting turntable 10. A limiting rod 12 is inserted into the through hole 11. The outer surface of the limiting rod 12 is squeezed and adapted to the groove on the outer surface of the first mattress 3.

[0036] The working principle of the above technical solution is as follows:

[0037] During use, the patient lies flat on the first mattress 3, the second mattress 5, and the third mattress 9, with both hands gripping the training device 6. Activating the training device 6 causes the patient's arms to perform chest-expanding exercises, thereby enhancing cardiopulmonary function and promoting rehabilitation. The driving support device 7 lifts the second mattress 5 upwards until it is in a vertical position. The limiting rod 12 is then pulled out, and the adjusting dial 10 is rotated to lower the third mattress 9 to a vertical position. The limiting rod 12 is then inserted into the through hole 11 aligned with the groove on the first mattress 3, thus fixing the adjusting dial 10 in its current position and maintaining the third mattress 9 in a vertical position. In the current state, the patient sits on the first mattress 3. The first telescopic rod 2 is remotely operated to extend or retract according to the patient's height and leg length, allowing the patient's feet to touch the ground and providing support. While adjusting the first telescopic rod 2, the stabilizing device 4 extends or retracts accordingly, providing support to the first mattress 3 and preventing damage to the first telescopic rod 2 after prolonged use. The patient sits on the first mattress 3, with their back against the vertical second mattress 5, and their hands on the training device 6, performing chest expansion exercises in a seated position. This improves the flexibility of the device, allowing the patient to choose between lying down or sitting positions for chest expansion exercises based on their own physical condition.

[0038] Example 2:

[0039] The other structures of this embodiment 2 are the same as those of embodiment 1. The difference is that the stabilizing device 4 includes a first connecting member 41. The bottom of the first connecting member 41 is fixedly connected to the upper surface of the base 1. A rotating sleeve 42 is rotatably connected inside the first connecting member 41. A connecting rod 43 is slidably connected to the inner surface of the rotating sleeve 42.

[0040] The outer surface of the connecting rod 43 passes through the rotating sleeve 42 and extends to the outside. The output end of the connecting rod 43 is rotatably connected to the fixing member 45. The outer surface of the fixing member 45 is fixedly connected to the lower surface of the first mattress 3. The end of the connecting rod 43 away from the fixing member 45 is fixedly connected to the telescopic spring 44. The end of the telescopic spring 44 away from the connecting rod 43 is fixedly connected to the bottom of the inner surface of the rotating sleeve 42.

[0041] The training device 6 includes a fixed frame 601. The outer surface of the fixed frame 601 is fixedly connected to the side of the outer surface of the second mattress 5. A forward and reverse motor 602 is fixedly connected to the top of the fixed frame 601. A worm gear 603 is fixedly connected to the output end of the forward and reverse motor 602. A connecting rod 604 is rotatably connected to the outer surface of the fixed frame 601.

[0042] A worm gear 605 is fixedly connected to the outer surface of the connecting rod 604. The connecting rod 604 and the worm gear 605 are symmetrically arranged on both sides of the worm 603. The outer surface of the worm gear 605 meshes with the outer surface of the worm 603. A bent rod 606 is fixedly connected to the output end of the connecting rod 604. A second telescopic rod 607 is fixedly connected to the outer surface of the bent rod 606.

[0043] A rubber sleeve 608 is fixedly connected to the output end of the second telescopic rod 607. A fixed grip rod 609 is fixedly connected to the inner surface of the rubber sleeve 608. An infrared sensor 610 is fixedly connected to the inner surface of the rubber sleeve 608.

[0044] With the stabilizing device 4, when the first telescopic rod 2 extends or retracts, the rotating sleeve 42 and the connecting rod 43 rotate under force, and the connecting rod 43 slides along the inner surface of the rotating sleeve 42, causing the telescopic spring 44 to extend or retract. On the one hand, the rotating sleeve 42 and the connecting rod 43 can provide support for the first mattress 3 and distribute the pressure on the first telescopic rod 2. While improving the stability of the device, it can also prevent the first telescopic rod 2 from suffering greater wear. On the other hand, during the lifting and lowering of the first mattress 3, the elasticity of the telescopic spring 44 can provide cushioning, further extending the service life of the first telescopic rod 2.

[0045] Through the training device 6, the patient's hands grip the fixed handle 609. The second telescopic rod 607 is remotely driven to extend or retract according to the patient's needs, facilitating a proper preparatory posture for chest expansion exercises. The device can be adjusted to suit different patients, improving its adaptability. Activating the forward / reverse motor 602 causes the worm gear 603 to rotate. Since the two worm wheels 605 mesh with the worm gear 603, the worm wheels 605 rotate, causing the two bent rods 606 to rotate in opposite directions, thus inducing the patient's arms to perform a chest expansion movement. Based on pre-set data, the forward / reverse motor 602 rotates in the opposite direction, bringing the patient's outstretched arms back to the chest, completing one chest expansion exercise. Repeating this process enhances the patient's cardiopulmonary function. When the patient's hands leave the rubber sleeve 608, the infrared sensor 610 transmits a signal to the forward / reverse motor 602 to stop its operation, improving safety during training.

[0046] Example 3:

[0047] The other structures of this embodiment 3 are the same as those of embodiments 1 and 2, except that the support device 7 includes an inner groove 71, which is opened on the lower surface of the second mattress 5. A stepper motor 72 is fixedly connected to the inner surface of the inner groove 71, and a screw 73 is fixedly connected to the output end of the stepper motor 72. A slider 74 is threadedly connected to the outer surface of the screw 73, and a second connector 75 is fixedly connected to the outer surface of the slider 74.

[0048] The second connector 75 is rotatably connected to a third telescopic rod 76. The end of the third telescopic rod 76 away from the second connector 75 is rotatably connected to a support rod 77. The bottom end of the support rod 77 is fixedly connected to a vacuum suction cup 78.

[0049] The support device 7 and vacuum suction cup 78 keep the entire support device 7 firmly attached to the ground. When the second mattress 5 needs to be adjusted, the stepper motor 72 and the third telescopic rod 76 are activated simultaneously, causing the screw 73 to rotate, the slider 74 to move along the outer surface of the screw 73, and the third telescopic rod 76 to extend until it reaches its maximum extension. At this time, the second mattress 5 rotates from a horizontal state to a vertical state, and the third telescopic rod 76 provides support for the second mattress 5. By adjusting the support device 7, the state of the second mattress 5 can be changed, allowing the patient to choose to perform chest expansion exercises in a lying or sitting position as needed. The adjustment method is simple and convenient, improving the flexibility of the device.

[0050] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
