Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation chairs, in particular to a cardiopulmonary function rehabilitation chair for middle-aged and elderly people. Background Art

[0002] With the aging of the population, the cardiopulmonary health of the middle-aged and elderly population is receiving increasing attention. Due to physiological deterioration, the elderly often experience decreased cardiopulmonary function (such as weakened myocardial contractility and reduced lung ventilation), muscle atrophy, and impaired balance. These individuals often also suffer from chronic conditions (such as coronary heart disease, chronic obstructive pulmonary disease, and hypertension), leading to an urgent need for cardiopulmonary rehabilitation. Therefore, rehabilitation chairs can provide a safe, comfortable, and targeted platform for rehabilitation training for the elderly, effectively addressing shortcomings in age-friendly design and becoming a key technology product in meeting the cardiopulmonary rehabilitation needs of the elderly. From the perspective of rehabilitation training safety, rehabilitation chairs, through their specialized structural design, can create a safe exercise space for the elderly.

[0003] Current cardiopulmonary function rehabilitation chairs for middle-aged and elderly people usually have a pulse sensor installed on the chair to monitor the patient's heart rate. If the patient's heart rate exceeds the preset range, the buzzer will sound an alarm to remind the patient to stop exercising in time and take proper rest. However, the heart rate preset range on existing rehabilitation chairs is mostly fixed at the factory and cannot be dynamically adjusted according to the patient's recovery status. When the patient feels okay during exercise and has the ability to continue training, it is not convenient to modify the heart rate preset range in real time according to the actual situation. Frequent alarms may cause anxiety in the patient. At the same time, the patient is forced to interrupt training due to the fixed threshold and cannot make full use of the period when the physical condition is good to increase the amount of training.

[0004] In addition, due to their weak physical functions, cardiopulmonary rehabilitation patients usually need to lean forward to mobilize their core strength when getting up from the rehabilitation chair. When the patient leans forward and the center of gravity moves forward, the rehabilitation chair lacks sufficient forward support points, which can easily cause the rehabilitation chair and the patient to fall forward as a whole. It may also slide backward under pressure. The backward movement will disrupt the patient's body balance, causing the center of gravity to lean backward and fall. Moreover, after cardiopulmonary function rehabilitation exercises, patients often feel obviously tired due to physical exhaustion. At this time, the action of getting up from the rehabilitation chair requires overcoming their own gravity and the support resistance of the rehabilitation chair, and the process of getting up is more strenuous.

[0005] In view of the above problems, a cardiopulmonary function rehabilitation chair for middle-aged and elderly people is proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide a cardiopulmonary function rehabilitation chair for middle-aged and elderly people. The present device is used to work, thereby solving the problems in the above background that it is inconvenient to modify the preset heart rate range in real time according to the actual situation, frequent alarms may cause anxiety in patients, and the rehabilitation chair lacks sufficient forward support points, which can easily cause the rehabilitation chair and the patient to fall forward as a whole.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] In order to solve the technical problems of inconvenience in modifying the preset heart rate range in real time according to the actual situation, frequent alarms may cause patients to be anxious, and patients are forced to interrupt training due to fixed thresholds, such as Figure 1-Figure 2 As shown, the following preferred technical solutions are provided:

[0040] A cardiopulmonary function rehabilitation chair for middle-aged and elderly people is characterized by comprising a rehabilitation chair body 80, a pulse sensor 1, a controller 20, a buzzer 30, an adjustment module 40 and a control switch 60. The pulse sensor 1, the controller 20, the buzzer 30, the adjustment module 40 and the control switch 60 are all arranged on one side of the rehabilitation chair body 80, and the pulse sensor 1, the controller 20, the buzzer 30, the adjustment module 40 and the control switch 60 are electrically connected.

[0041] When the pulse sensor 1 emits a light beam of a certain wavelength to the skin, and the controller 20 receives and processes the information through transmission or reflection, the patient's heart rate can be monitored. If the patient's heart rate exceeds the preset range of the controller 20, the controller 20 will drive the buzzer 30 to sound an alarm, reminding the patient to stop exercising in time and take a proper rest. If the patient continues to exercise, the controller 20 will turn off the buzzer 30 after five to ten seconds until the patient finishes exercising. Then, the threshold data of the patient's newly added exercise time is written into the storage unit of the controller 20 through the adjustment module 40, thereby changing the triggering condition of the buzzer 30 alarm. Therefore, the preset range in the controller 20 can be modified in real time, which is convenient for real-time modification of the heart rate preset range according to actual conditions, and the training volume can be fully utilized during the period when the body is in good condition.

[0042] In order to solve the technical problem that when the patient leans forward and the center of gravity moves forward, he may slide backward under pressure, resulting in falling and difficulty in getting up, such as Figure 3-Figure 9 、 Figure 11-Figure 15 As shown, the following preferred technical solutions are provided:

[0043] The rehabilitation chair body 80 includes a wheelchair body 2 and moving wheels 3 rotating on both sides of the wheelchair body 2. A pushing member 5 is provided on one side of the wheelchair body 2. The pushing member 5 is electrically connected to the control switch 60. The pushing member 5 can be controlled by the control switch 60. Resistance members 6 are fixedly installed on both sides of the wheelchair body 2 near the moving wheels 3. The resistance members 6 can lock the moving wheels 3. Support members 7 are installed on both sides of the wheelchair body 2. The pushing member 5 is fixedly connected to the support member 7. The support member 7 can be pushed out of the wheelchair body 2 by the pushing member 5, and then the front end of the wheelchair body 2 can be supported by the support member 7. A drive seat 8 is fixedly installed on one side of the wheelchair body 2. The driving seat 8 is electrically connected to the control switch 60, and the driving seat 8 can be controlled by the control switch 60. A push plate 9 is rotatably connected to one side of the wheelchair body 2, and a lifting member 10 is installed on one side of the driving seat 8. One end of the lifting member 10 is hinged to the pushing plate 9. The lifting member 10 can be driven to move by the driving seat 8, and the pushing plate 9 can be lifted by the lifting member 10, thereby pushing the patient to stand up. An exercise member 70 is slidably connected to one side of the wheelchair body 2, and the exercise member 70 is electrically connected to the control switch 60, and the exercise member 70 is connected to the driving seat 8. The exercise member 70 can be controlled by the control switch 60, and the exercise member 70 can be used to exercise the patient's legs.

[0044] First, the exercise piece 70 can be controlled by the control switch 60. The exercise piece 70 can exercise the patient's legs, and leg exercise can directly promote cardiopulmonary function. When the patient needs to get up, the control switch 60 can be used to control the pushing member 5 to push the support member 7 out of the wheelchair body 2. Then, the support member 7 can support the front end of the wheelchair body 2. At the same time, the support member 7 can drive the resistance member 6 to lock the moving wheel 3. Therefore, when the patient leans forward and moves the center of gravity forward, the support member 7 provides sufficient forward support points for the wheelchair body 2, which can prevent the wheelchair body 2 and the patient from tipping forward as a whole. By locking the moving wheel 3, the patient can be prevented from losing his balance and falling due to the pressure on the moving wheel 3 moving backward, thereby improving safety. At the same time, the control switch 60 can control the driving seat 8 to drive the lifting member 10 to move, and the lifting member 10 can push the pushing plate 9 to lift, thereby pushing the patient to get up. Therefore, it can help the patient get up after exercise, greatly reducing the difficulty of the patient getting up.

[0045] A rotating shaft 31 is fixedly connected to one side of the moving wheel 3, and the rotating shaft 31 is rotatably connected to the wheelchair body 2. The rotating shaft 31 and the wheelchair body 2 can be connected so that the moving wheel 3 can move better.

[0046] The pushing member 5 includes an electric push rod 51 and a connecting plate 52 fixed on the surface of the electric push rod 51. The electric push rod 51 can play a driving role. The connecting plate 52 is fixedly connected to the driving seat 8. The output end of the electric push rod 51 is fixedly connected to a horizontal plate 53. The two ends of the horizontal plate 53 are fixedly connected to concave plates 54. The connecting plate 52 can be driven to move by the electric push rod 51. When the connecting plate 52 moves, it can drive the concave plates 54 at both ends to move. The concave plates 54 can drive the support member 7 to move.

[0047] The resistance member 6 includes an arc plate 61 and a first connecting tube 62 fixed on one side of the arc plate 61. The first connecting tube 62 is communicated with the arc plate 61, and one end of the first connecting tube 62 is fixedly connected to the second connecting tube 63. The first connecting tube 62 and the second connecting tube 63 are connected by welding to improve the stability of the connection between the two. The second connecting tube 63 is communicated with the first connecting tube 62. A sliding rod 64 is connected to one side of the arc plate 61, and the sliding rod 64 is slidably connected to the first connecting tube 62 and the second connecting tube 63. One end of the sliding rod 64 is an inclined surface, and a circular plate 65 is fixedly connected to the surface of the sliding rod 64. The circular plate 65 is slidably connected to the first connecting tube 62. A first spring 66 is fixedly installed on one side of the circular plate 65, and one end of the first spring 66 is fixedly connected to the first connecting tube 62, which can provide elastic force through the first spring 66. A brake pad 67 is fixedly installed on one end of the sliding rod 64.

[0048] When the slide bar 64 is pressed down, the circular plate 65 can be driven to move downward, and then the circular plate 65 can squeeze the first spring 66. At this time, the slide bar 64 can drive the brake pad 67 to move downward, and the brake pad 67 contacts the rotating shaft 31. The friction between the brake pad 67 and the rotating shaft 31 is increased by the brake pad 67, which can prevent the moving wheel 3 from rotating, thereby improving the stability of the moving wheel 3 and preventing the patient from losing his balance and falling due to the backward rotation of the moving wheel 3 due to the pressure, thereby improving safety. When the downward pressure of the slide bar 64 disappears, the elastic force of the first spring 66 can push the circular plate 65 and the slide bar 64 to move upward, thereby driving the brake pad 67 to return to the initial position, so that the moving wheel 3 can continue to rotate.

[0049] The support 7 comprises a frame plate 71 and a moving block 72 slidably connected inside the frame plate 71, the moving block 72 is fixedly connected with the concave plate 54, when the concave plate 54 moves, the moving block 72 can be driven to move, an extension plate 73 is slidably clamped inside the frame plate 71, the extension plate 73 can be extended inside the frame plate 71 through movement, a first connecting plate 74 is fixedly installed on one side of the moving block 72, the first connecting plate 74 is slidably clamped with the extension plate 73, a second connecting plate 75 is rotatably connected at one end of the first connecting plate 74, the second connecting plate 75 is slidably connected with the extension plate 73, a third connecting plate 76 is rotatably connected at one end of the second connecting plate 75, the third connecting plate 76 is slidably connected with the extension plate 73, a supporting leg 77 is rotatably connected on one side of the extension plate 73, the supporting leg 77 can support the front end of the wheelchair body 2, the third connecting plate 76 is rotatably connected with the supporting leg 77.

[0050] The connecting plate 52 can be driven to move by the electric push rod 51, when the connecting plate 52 moves, the two concave plates 54 at both ends can be driven to move, the moving block 72 can be driven to move inside the frame plate 71 through the concave plate 54, since the first connecting plate 74 is slidably clamped with the extension plate 73, at this time, the extension plate 73 will be pushed to move first, and the extension plate 73 can be extended inside the frame plate 71, when the extension plate 73 moves to the top of the frame plate 71, since the frame plate 71 is limited, at this time, the extension plate 73 cannot move, since the moving block 72 continuously moves, the first connecting plate 74 and the extension plate 73 will be unclamped, therefore, the moving block 72 moves can drive the first connecting plate 74 and the second connecting plate 75 to move, the supporting leg 77 can be flipped and contacted with the ground through the pushing force of the first connecting plate 74, the second connecting plate 75 and the third connecting plate 76, the supporting leg 77 can provide sufficient forward support point for the wheelchair body 2 through the support of the supporting leg 77, which can prevent the wheelchair body 2 and the patient from being overturned forward as a whole.

[0051] Two rectangular grooves 711 are formed in one end of the frame plate 71, an L-shaped plate 721 is fixedly installed on one side of the moving block 72, the L-shaped plate 721 is slidably connected with the frame plate 71, a protrusion 722 is fixedly installed on one side of the L-shaped plate 721, the protrusion 722 is slidably connected with the wheelchair body 2, an insertion rod 723 is fixedly installed at one end of the L-shaped plate 721, the insertion rod 723 is slidably connected with the second connecting barrel 63, and the insertion rod 723 is in contact with the sliding rod 64, when the moving block 72 moves, the L-shaped plate 721 and the insertion rod 723 can be driven to move, and the movement of the L-shaped plate 721 can be limited by the protrusion 722, when the insertion rod 723 moves to the inside of the second connecting barrel 63 and continuously moves, the sliding rod 64 can be pressed down by the insertion rod 723.

[0052] When the locking cam 731 is in the closed position, the locking cam 732 is locked and the locking cam 733 is locked, so that the master latch 7 is locked and the master latch 7 is locked.

[0053] When the first connecting plate 74 moves, the elastic force of the second spring 732 can push the arc block 733 to engage with the first connecting plate 74. Therefore, when the first connecting plate 74 moves, it will first push the extension plate 73 to move. When the limit bar 731 contacts the end of the frame plate 71, the continuous pushing force will squeeze the arc block 733 and the second spring 732, so that the arc block 733 and the first connecting plate 74 are no longer engaged. Therefore, after the first connecting plate 74 moves, it can push the support leg 77 to flip over. When the support leg 77 is separated from the L-shaped clamping plate 735, the elastic force of the third spring 736 can push the L-shaped clamping plate 735 to insert into the rectangular groove 711, so as to limit the extension plate 73.

[0054] When the support leg 77 needs to be stored, the pulling force of the moving block 72 will drive the first connecting plate 74, the second connecting plate 75 and the third connecting plate 76 to move. Since the L-shaped card plate 735 inserted into the rectangular groove 711 can limit the extension plate 73, the extension plate 73 will not move toward the inside of the frame plate 71, so that the support leg 77 can be driven to flip over first until the support leg 77 pushes the L-shaped card plate 735 to move upward and separate from the rectangular groove 711. Then, the continuous pulling force of the first connecting plate 74, the second connecting plate 75 and the third connecting plate 76 can drive the extension plate 73 to move toward the inside of the frame plate 71, which can prevent the support leg 77 from not flipping over and causing the pulling force to rub against the ground, making it difficult to store the support leg 77.

[0055] The driving seat 8 comprises a support plate 81 and a first fixing frame 82 fixed at one end of the support plate 81, and a first motor 83 is fixedly installed on one side of the first fixing frame 82, and the first fixing frame 82 can support the first motor 83, and the support plate 81 is rotatably connected with a bidirectional screw rod 84, and the output end of the first motor 83 is fixedly connected with the bidirectional screw rod 84, and two positioning plates 85 are fixedly installed on one side of the support plate 81, and the first motor 83 can drive the bidirectional screw rod 84 to rotate, and the bidirectional screw rod 84 can drive the lifting piece 10 and the exercise piece 70 to relatively move.

[0056] The lifting piece 10 comprises a concave frame 101 and inclined grooves 102 provided through the concave frame 101 on both sides, the concave frame 101 is threadedly connected with the bidirectional screw rod 84, the concave frame 101 is slidably connected with the support plate 81, two vertical plates 103 are slidably connected in the concave frame 101, the two vertical plates 103 are hingedly connected with one side of the pushing plate 9, cylindrical columns 104 are fixedly installed on both sides of the vertical plate 103, the cylindrical columns 104 are slidably connected with the inclined grooves 102 and the positioning plates 85, when the first motor 83 drives the bidirectional screw rod 84 to rotate, the concave frame 101 is driven to move, and when the concave frame 101 moves, the two vertical plates 103 are driven to move upward by the limiting of the inclined grooves 102 and the positioning plates 85, so that one end of the pushing plate 9 is tilted upward, and the pushing plate 9 can push the patient to stand up, so that the patient can be assisted to stand up after exercise.

[0057] In order to solve the technical problem that the heart and lung rehabilitation patients are often in a state of muscle fatigue and decreased balance ability after leg exercise due to body function decline, and the forward inclination or the extended rotary rod 706 and the fixed foot pedal 707 significantly increase the risk of stumbling, Figure 4 and Figure 10 The following preferred technical solutions are provided:

[0058] The exercise piece 70 comprises a moving frame 701 and sliding blocks 702 fixed at both ends of the moving frame 701, the moving frame 701 is threadedly connected with the bidirectional screw rod 84, the moving frame 701 is slidably connected with the support plate 81, the sliding blocks 702 are slidably connected with the wheelchair body 2, a second fixing frame 703 is fixedly installed on one side of the sliding block 702, a second motor 704 is fixedly installed on one side of the second fixing frame 703, a rotating shaft 705 is fixedly installed at the output end of the second motor 704, the rotating shaft 705 is rotatably connected with the sliding block 702, a rotary rod 706 is fixedly installed at one end of the rotating shaft 705, and a fixed foot pedal 707 is rotatably connected on one side of the rotary rod 706.

[0059] The second motor 704 can drive the rotating shaft 705 to rotate, and the rotation of the rotating shaft 705 can drive the rotating rod 706 to swing up and down. The patient's feet can be fixed by the fixed footrest 707, so that the patient can be driven to perform end training. When the training is completed, the rotating rod 706 is in a vertical state. At this time, the first motor 83 can drive the bidirectional screw 84 to rotate, thereby driving the movable frame 701 to move into the wheelchair body 2, thereby driving the rotating rod 706 and the fixed footrest 707 to move into the wheelchair body 2 for storage. Since cardiopulmonary rehabilitation patients are often in a state of muscle fatigue and decreased balance ability after leg exercise due to the decline in physical function, the forward-leaning or extended rotating rod 706 and the fixed footrest 707 will significantly increase the risk of tripping. Therefore, moving them into the wheelchair body 2 can prevent the patient from tripping.
