Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training, and in particular to an intelligent sports rehabilitation training device and method. Background Art

[0002] Modern rehabilitation medicine research has deeply revealed the key impact of individual differences in the rehabilitation process. The physical physiological functions, pathological characteristics of injuries and diseases, and psychological cognitive states of different patients are intertwined, which determines the high degree of personalization of their rehabilitation needs. For example, even among stroke patients, the manifestations and severity of limb movement disorders vary greatly due to the different areas and degree of brain damage.

[0003] Existing rehabilitation training devices can only support the patient's rehabilitation movements, but cannot promote the patient's rehabilitation efficiency to a certain extent; and the patient's degree of recovery can often only be felt by the patient himself and told to the doctor orally so that the doctor can know the patient's recovery status.

[0004] To this end, the present invention provides an intelligent sports rehabilitation training device and method to solve the above problems. Summary of the invention

[0005] The present invention continuously squeezes the air pressure inside the cylinder when the piston rod reciprocates, thereby causing the airbag to expand and squeeze the patient's legs, thereby promoting smoother blood flow in the blood vessels and avoiding local blood stasis to form hematomas. At the same time, appropriate pressure can stimulate cells in tissues such as the periosteum and bone marrow around the injury, prompting them to more actively participate in the formation of callus, thereby improving the rehabilitation effect.

The reciprocating screw is fixedly connected to one end of two groups of pulleys close to the front end, and there are two groups of them. Piston rods are arranged on the outside of the two groups of reciprocating screws, and the piston rods are connected to the reciprocating screw ball nut pair.

[0008] Preferably: the piston rod is arranged inside the cylinder, the outer diameter of the piston rod matches the inner diameter of the cylinder, a fixing ring is arranged on the outside of the cylinder, the upper end of the fixing ring is fixedly connected to the bracket, the cylinder is fixed by the fixing ring, one end of the cylinder is fixedly connected to a connecting pipe, and the other end of the connecting pipe is connected to the airbag.

[0010] Preferably, the airbag is fixedly connected to the inner side of the knee pad, the upper ends of the two groups of telescopic rods are provided with slide grooves, and the slide grooves are located on the inner wall of the bracket, and the armrests are provided with protrusions at both ends, and the armrests are fixed by connecting the protrusions at both ends to the slide grooves.

[0011] Preferably: the lower end of the protrusion close to one end of the winding groove is fixedly connected with a rack A, and the lower end of the rack A is a storage groove. The spring is fixedly connected to the lower end of the rack A, and the other end of the spring is connected to the bottom of the storage groove. Both ends of the gear are connected to the bracket, and the gear is meshed with the rack A.

[0012] Preferably: a rack B is connected to one side of the gear, and the rack B is meshed with the gear. The upper end of the rack B is fixedly connected to a schematic rod, and the upper end of the schematic rod extends through the bracket to the upper end.

[0014] A method for using an intelligent sports rehabilitation training device comprises the following steps: S1: The user lifts the patient up and fixes the patient with a fixation belt. After fixation, the user pulls the telescopic rod to adjust the position between the two sets of knee pads to fix the patient's legs, and also prevents the patient's legs from everting outward when walking; S2: When the patient lies on the upper end of the armrest, the armrest will move downward due to gravity, so that the rack A will drive the gear to rotate, and when the gear rotates, it will drive the reeling groove to rotate and automatically tighten the fixing belt, thereby further strengthening the protection of the patient; S3: When the device moves, the pulley rotates, which drives the reciprocating screw to rotate synchronously, thereby driving the piston rod to reciprocate. When the piston rod reciprocates, the air pressure is continuously input into the airbag through the connecting tube, so that the airbag expands and squeezes the patient's legs. Compared with the prior art, the present invention has the following beneficial effects: 1. The invention continuously squeezes the air pressure inside the cylinder when the piston rod reciprocates, so that the air pressure inside the cylinder enters the connecting tube. Since the connecting tube is connected to the airbag, the connecting tube inputs air into the airbag, so that the airbag expands and squeezes the patient's legs, thereby promoting smoother blood flow in the blood vessels and avoiding local blood stasis to form hematomas. At the same time, appropriate pressure can stimulate cells in tissues such as the periosteum and bone marrow around the injury, prompting them to more actively participate in the formation of callus, thereby improving the rehabilitation effect.

[0015] 2. The invention causes rack B to rise synchronously when the armrest drives the gear to rotate when the armrest is lowered, and causes the indicator rod to rise synchronously when rack B rises. At the same time, since the upper end of the indicator rod is a magnetic block, it can be adsorbed with the decoration when in use, thereby reducing the boredom of the patient when using it. Moreover, the equipment has been proved based on multiple tests that when used by patients with more serious conditions, the pressure on the armrest will increase due to unstable standing, so that the indicator rod rises a greater distance. When used by patients with milder conditions, the pressure on the armrest is less, so that the indicator rod rises a shorter distance. Therefore, medical staff can preliminarily judge the patient's recovery status according to the amount of rise of the indicator rod.

[0016] 3. This invention drives the connecting shaft to rotate synchronously when the gear rotates, and drives the winding groove to reel synchronously when the connecting shaft rotates, thereby tightening the fixing belt to prevent patients with serious conditions from falling due to unstable standing during use.

A slide groove 11 is provided, and a handrail 12 is movably connected inside the slide groove 11. A rack A13 is fixedly connected to the lower end of the handrail 12, and a spring 14 is fixedly connected to the lower end of the rack A13. A gear 15 is provided at one end of the rack A13, and a rack B16 is provided on one side of the gear 15. A signal rod 17 is fixedly connected to the upper end of the rack B16, and a connecting shaft 18 is fixedly connected to one end of the gear 15, and a winding groove 19 is fixedly connected to one end of the connecting shaft 18. A fixing belt 20 is fixedly connected to the outer side of the bracket 1.

[0021] In an optional embodiment: four groups of pulleys 2 are arranged at the lower end of the bracket 1, and the four groups of pulleys 2 are all universally set. The reciprocating screw 3 is fixedly connected to one end of two groups of pulleys 2 near the front end, and there are two groups. Piston rods 4 are arranged on the outside of the two groups of reciprocating screws 3, and the piston rods 4 are connected to the reciprocating screw 3 ball nut pair. The universal setting of the pulley 2 is convenient for the patient to adjust the direction when using it, thereby reducing the burden on the patient. At the same time, because the reciprocating screw 3 is fixedly connected to the pulley 2, when the pulley 2 rotates, the reciprocating screw 3 will be driven to rotate synchronously, and when the reciprocating screw 3 rotates, the piston rod 4 will be driven to reciprocate.

[0022] In an optional embodiment: the piston rod 4 is arranged inside the cylinder 5, and the outer diameter of the piston rod 4 matches the inner diameter of the cylinder 5. A fixing ring is arranged on the outside of the cylinder 5, and the upper end of the fixing ring is fixedly connected to the bracket 1. The cylinder 5 is fixed by the fixing ring. A connecting tube 6 is fixedly connected to one end of the cylinder 5, and the other end of the connecting tube 6 is connected to the airbag 10. As described above, when the piston rod 4 reciprocates, it will continuously squeeze the air pressure inside the cylinder 5, so that the air pressure inside the cylinder 5 will enter the connecting tube 6. Since the connecting tube 6 is connected to the airbag 10, the connecting tube 6 will input air into the airbag 10, so that the airbag 10 expands and squeezes the patient's leg, thereby promoting the blood in the blood vessels to flow more smoothly, avoiding local blood stasis to form hematoma, and at the same time, appropriate pressure can stimulate cells in tissues such as periosteum and bone marrow around the injury, prompting them to more actively participate in the formation of callus, thereby improving the rehabilitation effect.

[0023] In an optional embodiment: two groups of telescopic rods 7 are fixedly connected to the inner side of the bracket 1, and the two groups of telescopic rods 7 have damping force. One end of the two groups of telescopic rods 7 is connected to a knee pad 8, and the outer side of the knee pad 8 is movably connected to a movable rod 9. The knee pad 8 is divided into two upper and lower groups, and the two groups are connected by the movable rod 9. The telescopic rods 7 can adjust the position of the knee pad 8 at will by telescoping, so that it is suitable for a variety of different patients when used, thereby reducing the cost of use.

[0024] In an optional embodiment: the airbag 10 is fixedly connected to the inner side of the knee pad 8, and a slide groove 11 is provided at the upper ends of the two sets of telescopic rods 7, and the slide groove 11 is located on the inner wall of the bracket 1. The armrests 12 have protrusions at both ends, and the armrests 12 are connected to the slide groove 11 by the protrusions at both ends for fixing. The slide groove 11 provides a guiding effect for the armrests 12 when they move, so as to prevent the armrests 12 from running off the track and causing them to get stuck, thereby affecting the use of the equipment. At the same time, the armrests 12 provide a support platform for patients to prevent patients with more serious conditions from being unable to stand independently and falling.

[0025] In an optional embodiment: a rack A13 is fixedly connected to the lower end of the protrusion near one end of the winding groove 19, and the lower end of the rack A13 is a storage groove. A spring 14 is fixedly connected to the lower end of the rack A13, and the other end of the spring 14 is connected to the bottom of the storage groove. Both ends of the gear 15 are connected to the bracket 1, and the gear 15 is meshed with the rack A13. As described above, when the armrest 12 descends, the rack A13 will be driven to descend synchronously, and when the rack A13 descends, the gear 15 will be driven to rotate. When the patient is not lying on the upper end of the armrest 12, the armrest 12 will automatically rebound through the rack A13 at the lower end.

[0026] In an optional embodiment: a rack B16 is connected to one side of the gear 15, and the rack B16 is meshed with the gear 15. The upper end of the rack B16 is fixedly connected to the indicator rod 17, and the upper end of the indicator rod 17 extends through the bracket 1 to the upper end. The upper end of the indicator rod 17 is connected to a magnetic seat, and the magnetic seat is larger than the through hole. As mentioned above, when the armrest 12 descends and drives the gear 15 to rotate, it will drive the rack B16 to rise synchronously, and when the rack B16 rises, it will drive the indicator rod 17 to rise synchronously. At the same time, because the upper end of the indicator rod 17 is a magnetic block, it can be adsorbed with the decoration when used, thereby reducing the boredom of the patient when using it. The equipment has been proved based on multiple tests that when patients with severe conditions use it, the pressure on the armrest 12 will increase due to unstable standing, so that the indicator rod 17 rises a greater distance. When patients with milder conditions use it, the squeezing of the armrest 12 is less, so that the indicator rod 17 rises a smaller distance, so that medical staff can preliminarily judge the patient's recovery based on the amount of rise of the indicator rod 17.

[0027] In an optional embodiment: the connecting shaft 18 is fixedly connected to one end of the gear 15, and the connecting shaft 18 extends through the bracket 1 to the outer end, and the winding groove 19 is connected to the connecting shaft 18, and the winding groove 19 rotates through the rotation of the connecting shaft 18. As described above, when the gear 15 rotates, it will synchronously drive the connecting shaft 18 to rotate, and when the connecting shaft 18 rotates, it will drive the winding groove 19 to wind synchronously, thereby tightening the fixing belt 20 to prevent patients with more serious conditions from falling due to unstable standing during use.

[0028] In an optional embodiment: the fixing belt 20 is fixedly connected to one side of the bracket 1, and the other end thereof is connected to the winding groove 19. The lower end of the fixing belt 20 is movably connected to a heat preservation cover 21, and the heat preservation cover 21 is detachable. Since the patient's resistance is relatively weak, the heat preservation cover 21 can be used according to actual conditions during use, thereby protecting the patient's condition from further deterioration.

[0029] This embodiment also discloses a method for using the intelligent sports rehabilitation training device, comprising the following steps: Step 1: The user lifts up the patient and fixes the patient with the fixing belt 20. After fixation, the position between the two sets of knee pads 8 is adjusted by pulling the telescopic rod 7 to fix the patient's legs, and at the same time, the patient's legs are prevented from everting outward when walking; Step 2: When the patient lies on the upper end of the armrest 12, the armrest 12 will move downward due to the effect of gravity, so that the rack A13 will drive the gear 15 to rotate, and when the gear 15 rotates, it will drive the winding groove 19 to rotate to automatically tighten the fixing belt 20, thereby further strengthening the protection of the patient; Step 3: When the device moves, the rotation of the pulley 2 will drive the reciprocating screw 3 to rotate synchronously, thereby driving the piston rod 4 to reciprocate. When the piston rod 4 reciprocates, the air pressure will be continuously input into the airbag 10 through the connecting tube 6, so that the airbag 10 will expand and squeeze the patient's legs.

[0030] Working principle: when using the device, the user lifts up the patient and fixes the patient with the fixing belt 20. After the fixation is completed, the position between the two sets of knee pads 8 is adjusted by pulling the telescopic rod 7 to fix the patient's legs. When the patient is not lying on the upper end of the armrest 12, the patient with a more serious condition will increase the pressure on the armrest 12 due to unstable standing, so that the distance the indicator rod 17 rises is larger. When the patient with a milder condition uses it, the pressure on the armrest 12 is smaller, so that the distance the indicator rod 17 rises is smaller, so that the medical staff can preliminarily judge the patient's condition according to the amount of the indicator rod 17 rising. The patient's recovery condition is determined by the armrest 12. When the patient is not lying on the upper end of the armrest 12, the armrest 12 will automatically rebound through the rack A13 at the lower end. When the pulley 2 rotates, the reciprocating screw 3 will be driven to rotate synchronously. When the reciprocating screw 3 rotates, the piston rod 4 will be driven to reciprocate. When the piston rod 4 reciprocates, the air pressure inside the cylinder 5 will be continuously squeezed, so that the air pressure inside the cylinder 5 will enter the connecting tube 6. The connecting tube 6 will input air into the airbag 10, so that the airbag 10 will expand and squeeze the patient's legs, thereby promoting the blood in the blood vessels to flow more smoothly and avoiding local stasis of blood to form hematoma.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
