Description

Technical Field

[0001] The present invention relates to the technical field of cardiopulmonary exercise therapy rehabilitation equipment, and in particular to a cardiopulmonary exercise rehabilitation training equipment for patients. Background Art

[0002] Before cardiopulmonary surgery, patients need to avoid strenuous exercise and usually need to lie in bed for a long time to cooperate with the doctor's monitoring of their cardiopulmonary condition. After the operation, they need to perform certain cardiopulmonary exercises to ensure the speed of recovery. Usually, the way to exercise cardiopulmonary function after surgery is walking training. Walking training can not only restore one's own cardiopulmonary function, but also exercise one's own lower limb muscles, thereby offsetting the negative effects of lower limb weakness caused by long-term bed rest.

[0003] Existing walking training methods usually require the accompaniment of medical staff. Medical staff can help patients walk to avoid the risk of falling, and can also accurately grasp the patient's exercise volume, so as to facilitate the recording of the patient's physical recovery. However, this method requires long-term companionship of medical staff, which increases the workload of medical staff. Therefore, it is gradually assisted by special walking rehabilitation equipment. The walking rehabilitation equipment in the existing technology has a simple structure and a single function. It does not have the function of recording the patient's exercise volume and also lacks a certain stability.

[0004] In order to solve the above problems, a rehabilitation training device that can record the patient's exercise volume and is sufficiently stable is proposed. Summary of the invention

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] refer to Figures 1 to 12 , a patient cardiopulmonary exercise rehabilitation training device, comprising a U-shaped support plate 1, a first connecting rod 101, a fixed armrest 2, a first L-shaped rod 21, a second connecting rod 29, a roller 9, a backrest 6, a seat plate 28, a first horizontal mounting plate 15, a second horizontal mounting plate 22, a counting plate 14, an operating mechanism, a flipping mechanism, a braking mechanism, and an exercise volume recording mechanism; Two fixed armrests 2 are respectively installed on the upper end of the horizontal plate of the U-shaped support plate 1, and operating mechanisms are respectively slidably installed behind the two fixed armrests 2. The U-shaped structure of the U-shaped support plate 1 is convenient for the patient to put his arms on it and fix the device by holding the armrests 2; The two operating mechanisms are respectively slidably mounted on the two vertical plates of the U-shaped support plate 1; The lower ends of the two vertical plates of the U-shaped support plate 1 are respectively fixed with the cross bar of the first L-shaped rod 21 through two first connecting rods 101; The front walls of the lower ends of the vertical rods of the two first L-shaped rods 21 are respectively fixedly mounted with the first ends of the second horizontal mounting plates 22; The first ends of the second connecting rods 29 are respectively fixedly mounted on the upper parts of the second ends of the two second horizontal mounting plates 22, and the second ends of the two second connecting rods 29 are respectively fixedly connected to the front ends of the cross bars of the first L-shaped rods 21 adjacent thereto; A same backrest 6 is fixedly installed between the front ends of the cross bars of the two first L-shaped bars 21, and the backrest 6 is installed below the cross plate of the U-shaped support plate 1, and the backrest 6 is installed on the front side of the two first connecting bars 101 close to the cross plate of the U-shaped support plate 1; A seat plate 28 is movably mounted on the rear wall of the backrest 6. The seat plate 28 is driven to flip by a flip mechanism. The flip mechanism is driven to work by an operating mechanism. The seat plate 28 can flip downward from the rear of the backrest 6 under the drive of the flip mechanism, so that the patient can rest conveniently. Rollers 9 are rotatably mounted on the outer walls of both ends of the two second horizontal mounting plates 22, and brake mechanisms are movably mounted above the two rollers 9 at the rear end, and the two brake mechanisms are movably mounted on the outer walls of the vertical rods of the first L-shaped rod 21 adjacent thereto; Both brake mechanisms are driven by the flipping mechanism. The flipping mechanism drives the seat plate 28 to flip downward and drives the brake mechanism at the same time, so that the two brake mechanisms restrict the rolling of the roller 9, thereby increasing the stability of the equipment. The same first horizontal mounting plate 15 is fixedly mounted between the front ends of the two second horizontal mounting plates 22, and a counting plate 14 is mounted on the upper end of the horizontal mounting plate 15. The counting plate 14 is used to count the specific data of the user after using the device. When the patient uses the device without the accompaniment of medical staff, the medical staff only needs to use the counting plate 14 to know the specific amount of movement of the patient; An exercise volume recording mechanism is installed on the front wall of the counting board 14. The two rollers 9 located at the front end drive the exercise volume recording mechanism to work by rotation. The forward movement of the device is mainly driven by the patient's own walking, and the rollers 9 can reflect the patient's walking data when driving the device forward.

[0022] The brake mechanism comprises a semicircular ring 27, a first rectangular slider 23, a second rectangular slider 25, and a first connecting rod 24; The vertical rods of the two first L-shaped rods 21 are respectively provided with first rectangular through slots 2101, and first rectangular sliding blocks 23 are respectively slidably installed in the two first rectangular through slots 2101; Semicircular rings 27 are fixedly mounted on the outer walls of the two first rectangular sliders 23 through connecting pieces, and the inner diameters of the two semicircular rings 27 are respectively equal to the outer diameters of the two rollers 9 located at the rear end; The two semicircular rings 27 are in detachable contact with the rollers 9 adjacent thereto; Rubber rings for increasing friction are installed on the inner walls of the two semicircular rings 27; The first connecting shafts are fixedly mounted on the inner walls of the two first rectangular sliding blocks 23, and the first ends of the first connecting rods 24 are rotatably mounted on the two first connecting shafts. The two second horizontal mounting plates 22 are respectively provided with second rectangular through grooves 2201, in which second rectangular sliders 25 are respectively slidably mounted, and second connecting shafts are respectively fixedly mounted on the inner walls of the two second rectangular sliders 25; The second ends of the two first connecting rods 24 are respectively rotatably sleeved on the second connecting shafts close thereto; The two second rectangular slide blocks 25 are driven to slide by the flipping mechanism. Figure 4 The two second rectangular sliders 25 start to slide under the drive of the flipping mechanism, and during the sliding process, they drive the first connecting rods 24 on both sides to start to deflect. During the deflection process, the first connecting rods 24 on both sides respectively drive the first rectangular sliders 23 matched therewith to start to slide up and down along the first rectangular through grooves 2101 on both sides. When the first rectangular sliders 23 on both sides slide downward, the semicircular rings 27 fixed thereto also slide downward synchronously, and gradually contact the roller 9 close thereto during the downward sliding process. After contacting the roller 9, the rubber ring at its lower end starts to resist the roller 9 to prevent the roller 9 from continuing to roll, thereby achieving braking.

[0023] The turning mechanism comprises a first disc 20 and a second connecting rod 19; A cavity is installed at the rear end of the backrest 6, and both sides of the lower end of the seat plate 28 are respectively installed on the side walls of the cavity by rotating through the main shaft; The outer ends of the two main shafts rotate and penetrate the two side walls of the cavity respectively, and the first disc 20 is fixedly installed; A third connecting shaft is fixedly mounted at the eccentric position of the two first discs 20, and the first end of the second connecting rod 19 is rotatably mounted on the two third connecting shafts. Fourth connecting shafts are fixedly mounted on the outer walls of the two second rectangular sliding blocks 25 respectively; The second ends of the two second connecting rods 19 are respectively rotatably sleeved on the outer wall of the fourth connecting shaft close thereto; The two first disks 20 are driven to rotate by the operating mechanism. Figure 5 When the two first discs 20 start to rotate driven by the operating mechanism, the third connecting shaft located at the eccentric position of the outer wall also starts to rotate with the first disc 20, and while rotating, it drives the second connecting rods 19 on both sides to start reciprocating deflection. When the second connecting rods 19 on both sides are in the process of reciprocating deflection, they can respectively drive the second rectangular sliding blocks 25 matched therewith to start reciprocating sliding along the second rectangular through grooves 2201 on both sides.

[0024] The operating mechanism includes a movable armrest 17, an n-shaped slider 16, and a third connecting rod 18; The two vertical plates of the U-shaped support plate 1 are respectively slidably connected with an n-shaped slider 16, and the n-shaped slider 16 is movably installed between two first connecting rods 101 close thereto; The upper ends of the horizontal plates of the two n-shaped sliders 16 are respectively fixed with movable armrests 17, and the two movable armrests 17 are respectively movably mounted on the rear side of the fixed handle 2 close thereto; A fifth connecting shaft is fixedly mounted on the outer vertical plates of the two n-shaped sliders 16; The first ends of the third connecting rods 18 are respectively mounted on the outer walls of the two fifth connecting shafts. The second ends of the two third connecting rods 18 are respectively rotatably sleeved on the outer ends of the third connecting shafts close thereto; The two third connecting rods 18 are movably mounted on the outer sides of the second connecting rods 19 close thereto. Fig.10 The user pushes the movable armrests 17 on both sides to slide toward the fixed armrests 2 on both sides, and finally pinches the movable armrests 17 and the fixed armrests 2. In this process, the n-shaped sliders 16 on both sides also slide forward with the movable armrests 17 on both sides, and drive the third connecting rods 18 on both sides to start deflecting during the sliding process. The third connecting rods 18 on both sides start to drive the first discs 20 on both sides to start rotating during the deflection process, thereby driving the above-mentioned second connecting rod 19 to deflect.

[0025] The motion volume recording mechanism comprises a reciprocating screw rod 13, a threaded slider 12, a first T-shaped slider 1201, a second T-shaped slider 25, a spring telescopic rod 2501, and a return spring 26; A first T-shaped slide groove 1501 is provided at the upper end of the first horizontal mounting plate 15, and a horizontal plate of the first T-shaped slider 1201 is slidably mounted in the first T-shaped slide groove 1501; A threaded slider 12 is fixedly mounted on the upper end of the vertical plate of the first T-shaped slider 1201, and the threaded slider 12 is movably mounted on the front side of the counting plate 14; The internal thread of the threaded slider 12 is penetrated by a reciprocating screw rod 13, and the two ends of the reciprocating screw rod 13 are respectively rotated to penetrate the second connecting rod 29 close thereto and are fixedly connected to the two rollers 9 at the front end; A second T-shaped slide groove 1202 is provided on the rear wall of the threaded slide block 12, and a cross plate of the second T-shaped slide block 25 is slidably installed in the second T-shaped slide groove 1202; The lower end of the horizontal plate of the second T-shaped sliding block 25 is connected to the bottom wall of the second T-shaped sliding groove 1202 via a return spring 26; A spring telescopic rod 2501 is installed on the outer wall of the vertical plate of the second T-shaped slider 25; The counting plate 14 is provided with a plurality of horizontal grooves 1401 distributed at equal intervals, and the heads and tails of two adjacent horizontal grooves 1401 are connected by a vertical groove; The upper ends of the plurality of transverse grooves 1401 are all provided with counting scale lines, and the outer sides of the two ends of the plurality of transverse grooves 1401 are respectively provided with statistical scale lines; The spring telescopic rod 2501 can be detachably slidably installed in one of the horizontal grooves 1401 or one of the vertical grooves, Figure 8Before the device moves, the spring telescopic rod 2501 is located at the leftmost end of the lowest horizontal groove 1401. As the device moves, the roller 9 starts to drive the reciprocating screw rod 13 to start rotating, and during the rotation, it drives the threaded slider 12 that is threadedly penetrated therewith to start reciprocating sliding. The cooperation between the first T-shaped slider 1201 at the lower end of the threaded slider 12 and the first T-shaped slide groove 1501 at the upper end of the first horizontal mounting plate 15 defines the sliding trajectory of the threaded slider 12 and ensures that it will not deviate during the sliding process. During the horizontal reciprocating sliding process, the threaded slider 12 also drives the spring telescopic rod 2501 to start sliding horizontally, and slides along the lowest horizontal groove 1401 during the sliding process. As the spring telescopic rod 2501 slides to the rightmost end of the lowest horizontal groove 1401, the spring telescopic rod 2501 will slide along the vertical groove into the second horizontal groove 1401. At this time, the threaded slider 12 is just at the time when one stroke is completed and the reverse sliding begins. As the threaded slider 12 slides in the reverse direction, the spring telescopic rod 2501 also starts The spring telescopic rod 2501 slides to the left in the second transverse groove 1401. As the device continues to operate, the threaded slider 12 slides back and forth and finally slides the spring telescopic rod 2501 to the leftmost end of the uppermost transverse groove 1401. At this time, the amount of exercise reaches the maximum. After the patient uses the device, the medical staff can judge the specific amount of exercise of the patient by observing the specific position of the spring telescopic rod 2501 on the transverse groove. For example, after the patient has finished using the device, the spring telescopic rod 2501 is in the middle position of the third transverse groove 1401. If the third horizontal groove is 1000 steps, the spring telescopic rod 2501 being in the third horizontal groove 1401 means that the patient has walked 3000 steps. According to the scale line on the third horizontal groove 1401 being in the middle position of 500 steps, the specific number of steps of the patient is calculated to be 3500 steps. When the device needs to be reset, just move the device so that the threaded slider 12 is at the far left end, press the spring telescopic rod 2501 to make the second T-shaped slider 25 fall off to the lower end of the second T-shaped slide groove 1202, and then start counting again.

[0026] Horizontal rods 7 are respectively vertically mounted on the outer walls of the upper ends of the vertical rods of the two first L-shaped rods 21, and two expansion rods 8 are respectively fixedly mounted on the outer ends of the two horizontal rods 7; The two expansion rods 8 on the same side are arranged at an obtuse angle; Auxiliary wheels 10 are rotatably mounted on the outer walls of the lower ends of the four expansion rods 8 , and the expansion rods 8 arranged at obtuse angles on both sides increase the horizontal stability of the device and can effectively prevent the device from tipping over.

[0027] Storage boxes 11 for storing equipment are respectively installed at the lower ends of the two horizontal rods 7. The two storage boxes 11 are respectively installed on the inner sides of the two expansion rods 8 close thereto. Monitoring equipment for monitoring the patient's cardiopulmonary data can be stored in the storage boxes 11, which facilitates doctors to timely control the patient's physical condition.

[0028] A crossbar of a second L-shaped rod 3 is vertically mounted on the outer wall of one of the vertical plates of the U-shaped support plate 1; A second disc 4 is rotatably mounted on the upper end of the vertical rod of the second L-shaped rod 3; A plurality of hooks 5 for hanging hanging bottles are installed at equal angles at the eccentric position of the lower end of the second disc 4, so as to facilitate the patient to carry out rehabilitation training during the infusion process if the patient's body permits.

[0029] Implementation method of the present invention: When the device is in the initial state, the threaded slider 12 is located at one end of the first horizontal mounting plate 15, the seat plate 28 is in a downward flipped state, the semicircular rings 27 on both sides are against the rollers 9 on both sides, and the device is in a braking state. When the patient needs to use the device to walk, the movable armrests 17 on both sides are pushed to make them close to the fixed armrests 2 on both sides. In this process, the semicircular rings 27 on both sides gradually separate from the rollers 9, that is, the rolling restriction on the rollers 9 is released; When the semicircular rings 27 on both sides are lifted up, the seat plate 28 is lifted up and put into the cavity behind the backrest. At this time, the user can hold the movable armrest 17 and the fixed armrest 2 on the same side with both hands to start walking and drive the device to move. When the device is moving, the two rollers 9 at the front end start to rotate and drive the reciprocating screw 13 to rotate during the rotation. The threaded slider 12 that cooperates with the reciprocating screw 13 also starts to slide back and forth at this time, and drives the spring telescopic rod 2501 to slide back and forth during the sliding process. The sliding trajectory of the spring telescopic rod 2501 is respectively limited by a number of connected horizontal grooves 1401 and vertical grooves. Therefore, the spring telescopic rod 2501 can always slide along the horizontal grooves and vertical grooves as the threaded slider 12 slides. When the device stops, the medical staff can know how many circles the roller 9 has rotated by observing the specific position of the spring telescopic rod 2501. This data directly reflects the travel distance of the device and indirectly reflects the number of steps the patient has walked. Since some patients still need nutritional supplements after surgery, usually they need infusion to supplement, and if the physical condition allows, the patient can hang the infusion bottle on the hook 5, and perform walking and moving training while receiving infusion, which is more convenient to use; When the patient needs to sit or stand for a rest during training, the movable armrests 17 on both sides are released. At this time, the movable armrests 17 on both sides will separate as the semicircular rings 27 on both sides fall off. As the semicircular rings 27 on both sides fall off due to gravity and again touch the two rollers 9 at the rear end, the device is braked and the seat plate 28 is flipped down again. At this time, the patient can sit on the seat plate 28 to rest. Since the device is in a braked state at this time, the device is extremely stable when sitting or standing for a rest, and with the support of the expansion rods 8 set at obtuse angles on both sides, it will not easily roll over, and has strong safety.

[0030] The seat plate of the present invention can drive the brake mechanism at the same time when it is flipped downward, so that the roller is locked by the brake mechanism when the seat plate is lowered, thereby increasing the stability of the equipment. The operating mechanism of the present invention can release the brake mechanism only when the user holds the movable armrest and the fixed armrest at the same time, thereby removing the movement restriction of the equipment and having strong safety. The exercise volume recording mechanism of the present invention can count the exercise volume of the patient user, thereby avoiding the disadvantage of labor-intensive manual recording and observation.
