Description

Technical Field

[0001] The utility model belongs to the technical field of cardiovascular nursing and relates to an auxiliary walking device for cardiovascular internal medicine rehabilitation. Background Art

[0002] Cardiovascular and cerebrovascular diseases are a general term for cardiovascular and cerebrovascular diseases, and generally refer to ischemic or hemorrhagic diseases of the heart, brain and systemic tissues caused by hyperlipidemia, blood viscosity, atherosclerosis, hypertension, etc. Since cardiovascular and cerebrovascular diseases cause serious damage to the body's functions, rehabilitation treatment is particularly important in the later stages of treatment. After the patient's condition stabilizes, start with simple passive exercises and gradually do active exercises to eventually achieve the goal of self-care.

[0003] In a Chinese patent with announcement number CN213666599U, a rehabilitation auxiliary walking device for cardiovascular care is disclosed, and its technical solution is as follows: it includes a first U-shaped frame and a second U-shaped frame, the first U-shaped frame and the second U-shaped frame are symmetrically arranged, the left and right sides of the lower ends of the first U-shaped frame and the second U-shaped frame are fixedly connected by connecting rods, the left and right sides and the rear side of the upper end of the second U-shaped frame are provided with through holes for the second support column to pass through, the upper ends of the three groups of second support columns are commonly fixedly connected to the seat plate, the outer side of the second support column is fixedly connected to the boss, the second support column is sleeved with a spring, and the lower end of the second support column is fixedly connected to a positioning plate. Two sets of universal wheels are fixedly installed on the lower end surfaces of the first U-shaped frame and the second U-shaped frame. However, there are still the following disadvantages: during the use of the patient, since the seat plate cannot be folded, the space on the device becomes smaller, thereby affecting the rehabilitation effect.

[0004] In a Chinese patent with announcement number CN213553486U, a rehabilitation walking vehicle for cardiovascular care is disclosed, and its technical solution is as follows: it includes a support beam and a seat plate, there are two support beams, and the upper surfaces of one ends of the two support beams are fixedly connected with first support columns, and a first cross beam is fixedly connected between the first support columns, and one side of the first cross beam is fixedly connected with two first pins, and the two first pins are hinged with first connecting columns, and the other ends of the two first connecting columns are fixedly connected with electric push rods, and the sides of the two first support columns close to each other are fixedly connected with sleeves, and both sides of the seat plate are fixedly connected with sliding rods, and the surface of the sliding rod is located in the sleeve, and the lower surface of the seat plate is fixedly connected with two second pins, and the two second pins are hinged with second connecting columns, and the other ends of the electric push rods are respectively fixedly connected to the other ends of the two second connecting columns. However, the following disadvantages still exist: when the electric push rod is extended, the seat plate will rotate around the central axis of the slide rod and gradually tend to a horizontal state, but when the electric push rod is contracted, the seat plate will not be completely retracted to a vertical state, thereby reducing the room for the patient's legs to move and affecting the rehabilitation effect.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1-Figure 3 As shown, the technical solution adopted by the utility model is as follows: an auxiliary walking device for cardiovascular rehabilitation, comprising a support frame 1, the support frame 1 is a square frame structure. Two first support rods 2 are symmetrically fixedly connected to the top surface of the support frame 1, the upper ends of the two first support rods 2 are fixedly connected to a support platform 5, and the top surface of the support platform 5 is fixedly connected to two handrails 3.

[0027] The top surface of the support frame 1 is also symmetrically fixedly connected to two second support rods 7, a backrest 6 is fixedly connected between the two second support rods 7, and a sponge pad is fixedly connected to the side of the backrest 6 close to the support platform 5, and the sponge pad fits the patient's back, thereby improving the patient's comfort. A rotating shaft 9 is also rotatably connected between the two second support rods 7, and a seat plate 8 is fixedly connected to the rotating shaft 9. When a person uses the device for rehabilitation training, the seat plate 8 is in a vertical state, thereby providing more space for the patient's legs. A groove is provided on the side of the support platform 5 close to the seat plate 8 to further increase the patient's exercise space.

[0028] The support frame 1 is provided with a driving assembly for driving the seat plate 8 to rotate around the central axis of the rotating shaft 9. The driving assembly includes a motor 12, and the motor 12 is fixedly connected to the support frame 1. Two first slide grooves 16 are symmetrically provided on the support frame 1. The output shaft of the motor 12 extends into the first slide groove 16 on the same side and is fixedly connected with a screw rod 18, the other end of the screw rod 18 is rotatably connected to the inner wall of the corresponding first slide groove 16, and a guide rod 20 is fixedly connected to the other first slide groove 16. Slide blocks 19 are slidably connected in both first slide grooves 16, and the screw rod 20 is threadedly connected to the corresponding slide block 19, and the guide rod 20 is slidably connected to the corresponding slide block 19. The two slide blocks 19 are both hinged to one end of the connecting rod 10, and the other ends of the two connecting rods 10 are both hinged to a fixed seat 11, and the two fixed seats 11 are both fixedly connected to the side of the seat plate 8 close to the motor 12.

[0029] A button 4 is provided on the top surface of the support platform 5 , and the button 4 is electrically connected to the motor 12 .

[0030] Four wheels are installed on the bottom surface of the support frame 1. The four wheels are specifically two universal wheels 13 and two brake wheels 14, and a linkage assembly is arranged between the two brake wheels 14 and the corresponding sliders 19. Each linkage assembly includes a limit plate 15, a slide bar 17 and a first spring 21. Two second slide grooves 22 are provided on the support frame 1, and the upper end of the limit plate 15 is slidably connected in the second slide groove 22. The first spring 21 is located in the second slide groove 22, and one end is fixedly connected to the inner wall of the second slide groove 22, and the other end is fixedly connected to the limit plate 15. One end of the slide bar 17 is fixedly connected to the side of the limit plate 15 away from the first spring 21, and the other end passes through the support frame 1 and extends into the first slide groove 16 and cooperates with the slider 19, and the slide bar 17 is slidably connected to the support frame 1. The outer surfaces of the two brake wheels 14 are serrated, and the two limit plates 15 are L-shaped. The lower ends of the limit plates 15 cooperate with the corresponding brake wheels 14, so that when the patient sits on the seat plate 8 to rest, the brake wheels 14 can be prevented from rotating, thereby ensuring the overall stability of the device.

[0031] Working principle: In summary, in the initial state, the slider 19 is located on the side of the first slide slot 16 close to the motor 12 .

[0032] When using the device, a person helps the patient into the support frame 1 so that the patient is located between the support platform 5 and the backrest 6. The patient holds the handrails 3 with both hands and then walks forward slowly, thereby achieving the purpose of assisting rehabilitation exercise.

[0033] When the patient needs to rest, the patient presses the button 4, which starts the motor 12. The output shaft of the motor 12 drives the screw 18 to rotate, and the screw 18 drives the slider 19 to move to the side away from the motor 12. At the same time, the slider 19 drives the seat plate 8 and the rotating shaft 9 to rotate around the central axis of the rotating shaft 9 through the connecting rod 10 and the fixed seat 11. When the seat plate 8 rotates to a horizontal state, the slider 19 slides to the end of the first slide groove 16 away from the motor 12, and the motor 12 is turned off.

[0034] The patient then sits on the seat plate 8 to rest, or can lean his back against the backrest 6. Since the backrest 6 is provided with a sponge pad, the patient's comfort can be improved.

[0035] During the sliding process, the slider 19 gradually approaches the slide bar 17. After the slider 19 and the slide bar 17 are matched, the slider 19 pushes the slide bar 17 to move, and the slide bar 17 pushes the limit plate 15 to move, and at the same time compresses the first spring 21. When the lower end of the limit plate 15 is inserted between two adjacent serrations on the outer surface of the brake wheel 14, the slide bar 17 stops moving. At this time, the brake wheel 14 is limited and cannot rotate, so that the entire device cannot move, preventing the device from moving accidentally when the patient is resting.

[0036] Example 2

[0037] like Figure 4-Figure 6 As shown, an auxiliary walking device for cardiovascular rehabilitation includes a support frame 1, which is a square frame structure. Two first support rods 2 are symmetrically fixedly connected to the top surface of the support frame 1, and the upper ends of the two first support rods 2 are fixedly connected to a support platform 5. The top surface of the support platform 5 is fixedly connected to two armrests 3.

[0038] The top surface of the support frame 1 is also symmetrically fixedly connected to two second support rods 7, a backrest 6 is fixedly connected between the two second support rods 7, and a sponge pad is fixedly connected to the side of the backrest 6 close to the support platform 5, and the sponge pad fits the patient's back, thereby improving the patient's comfort. A rotating shaft 9 is also rotatably connected between the two second support rods 7, and a seat plate 8 is fixedly connected to the rotating shaft 9. When a person uses the device for rehabilitation training, the seat plate 8 is in a vertical state, thereby providing more space for the patient's legs. A groove is provided on the side of the support platform 5 close to the seat plate 8 to further increase the patient's exercise space.

[0039] The support frame 1 is provided with a driving assembly for driving the seat plate 8 to rotate around the central axis of the rotating shaft 9. The driving assembly includes a motor 12, which is fixedly connected to the support frame 1. Two first slide grooves 16 are symmetrically provided on the support frame 1. The output shaft of the motor 12 extends into the first slide groove 16 on the same side and is fixedly connected with a screw rod 18, the other end of the screw rod 18 is rotatably connected to the inner wall of the corresponding first slide groove 16, and a guide rod 20 is fixedly connected to the other first slide groove 16. Slide blocks 19 are slidably connected in both first slide grooves 16, the screw rod 18 is threadedly connected to the corresponding slide block 19, the guide rod 20 is slidably connected to the corresponding slide block 19, both slide blocks 19 are hinged to one end of the connecting rod 10, and the other ends of the two connecting rods 10 are hinged to a fixed seat 11, and both fixed seats 11 are fixedly connected to the side of the seat plate 8 close to the motor 12.

[0040] A button 4 is provided on the top surface of the support platform 5 , and the button 4 is electrically connected to the motor 12 .

[0041] Four wheels are installed on the bottom surface of the support frame 1. The four wheels are specifically four universal wheels 13.

[0042] Two guide posts 24 are fixedly connected to the bottom surface of the support frame 1, and a brake plate 25 is also provided below the support frame 1 for upward and downward movement, and the brake plate 25 is slidably connected to the two guide posts 24. Second springs 23 are sleeved on the two guide posts 24, and the upper ends of the two second springs 23 are fixedly connected to the support frame 1, and the lower ends are fixedly connected to the brake plates 25. Both ends of the rotating shaft 9 pass through the corresponding second support rods 7 and are fixedly sleeved with winding wheels 26, and the outer circumferential surfaces of the two winding wheels 26 are both concave arc-shaped and fixedly connected with ropes 27, which are wound around the corresponding winding wheels 26, and the lower ends of the two ropes 27 are fixedly connected to the brake plates 25.

[0043] Working principle: In summary, in the initial state, the sliders 19 are located on the side of the first slide slot 16 close to the motor 12, and the two second springs 23 are in a compressed state.

[0044] When using the device, a person helps the patient into the support frame 1 so that the patient is located between the support platform 5 and the backrest 6. The patient holds the handrails 3 with both hands and then walks forward slowly, thereby achieving the purpose of assisting rehabilitation exercise.

[0045] When the patient needs to rest, the patient presses the button 4, which starts the motor 12. The output shaft of the motor 12 drives the screw 18 to rotate, and the screw 18 drives the slider 19 to move to the side away from the motor 12. At the same time, the slider 19 drives the seat plate 8 and the rotating shaft 9 to rotate around the central axis of the rotating shaft 9 through the connecting rod 10 and the fixed seat 11. When the seat plate 8 rotates to a horizontal state, the slider 19 slides to the end of the first slide groove 16 away from the motor 12, and the motor 12 is turned off.

[0046] The patient then sits on the seat plate 8 to rest, or can lean his back against the backrest 6. Since the backrest 6 is provided with a sponge pad, the patient's comfort can be improved.

[0047] During the rotation of the rotating shaft 9, the two winding wheels 26 are driven to rotate, and the two winding wheels 26 lower the rope 27 wound around their outer surfaces. At the same time, the two second springs 23 release the stored elastic potential energy, pushing the brake plate 25 to move downward along the central axis of the guide column 24. After the winding wheels 26 completely release the rope 27, the rotating shaft 9 stops rotating. The brake plate 25 is in contact with the ground, and the rope 27 is in a relaxed state, and the two second springs 23 are still in a compressed state. The two second springs 23 apply a downward force to the brake plate 25, increasing the friction between the brake plate 25 and the ground.

[0048] The brake plate 25 is in contact with the ground, which can effectively prevent the wheels from continuing to roll when the patient is resting, thereby preventing accidents from occurring.

[0049] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
