Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to an upper limb rehabilitation and nursing device for stroke patients. Background Technology

[0002] Stroke, also known as apoplexy, is an acute cerebrovascular disease. In the early treatment of stroke, it is very important to help patients with upper limb rehabilitation care. This is mainly because stroke can lead to a decline in the function of the upper limbs and hands. Rehabilitation training can help restore these functions and reduce sequelae.

[0003] Currently, there are devices on the market that can help patients with upper limb rehabilitation training. For example, the Chinese utility model patent disclosed in announcement number CN215231953U discloses an upper limb rehabilitation training device for stroke patients. By setting up a training mechanism to help patients perform hand rehabilitation exercises, it can train patients to treat hand tremors. Although existing rehabilitation equipment can complete rehabilitation training for patients with hand tremors, patients in the early stages of stroke not only experience decreased hand muscle function, but also joint stiffness and upper limb muscle atrophy. Such rehabilitation equipment for the hand cannot help patients with joint and muscle rehabilitation training. Utility Model Content

[0004] The purpose of this application is to provide an upper limb rehabilitation and nursing device for stroke patients to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: an upper limb rehabilitation and nursing device for stroke patients, including a seat, an axially movable part fixed to the outside of the seat, a bracket fixed to the movable end of the axially movable part, two traction units connected to one side of the bracket, two sleeve parts located on the upper part of the seat and used to be sleeved on the outside of the upper limb, and two sets of traction lines respectively connecting the two sleeve parts to the two traction units.

[0006] In one embodiment, the sleeve includes a housing with a hollow groove inside, two support rods rotatably connected to the outside of the housing, and two traction holes opened inside the two support rods. The number of traction lines in a set is two, and one end of each traction line is tied to the traction hole inside the two support rods.

[0007] In one embodiment, an airbag is fixed to the inner wall of the hollow groove, and two air supply parts for supplying gas to the airbag are symmetrically fixed to both sides of the seat.

[0008] In one embodiment, the traction unit includes a housing fixed to one side of the bracket, two traction rods and two shafts rotatably connected inside the housing, two gears fixed to the outside of the two traction rods, two gears fixed to one end of the two shafts and meshing with the gears, and two servo motors fixed to one side of the housing. The other ends of the two shafts are rotatably connected to the inner wall of the housing. The output shafts of the two servo motors pass through the housing and are fixed to the two gears. The other end of the traction line passes inside the housing and is wound around the outside of the traction rods.

[0009] In one embodiment, two positioning gears are fixedly connected to the outside of the two shafts respectively, and two positioning sockets are slidably connected inside the housing. Two electric push rods are fixedly connected to both sides of the housing, and the telescopic ends of the two electric push rods penetrate into the inside of the housing and are fixedly connected to one end of the two positioning sockets respectively. The other end of the positioning socket is used to insert into two adjacent teeth on the outside of the positioning gear to restrict the rotation of the positioning gear.

[0010] In one embodiment, the axially movable part includes two bases fixed to both sides of the seat, movable grooves opened inside the two bases, two slides respectively slidably connected in the two movable grooves, a guide rod fixed in one of the movable grooves and movably inserted in one of the slides, a lead screw rotatably connected to the inner wall of the other movable groove and screwed into the other slide, and a drive part fixed to one side of one of the bases, wherein the output shaft of the drive part passes through the base and is fixedly connected to one end of the lead screw, and the upper ends of the two slides are fixedly connected to the lower end of the bracket.

[0011] Compared with the prior art, the beneficial effects of this application are:

[0012] 1) This application is equipped with a traction unit. Through the cooperation of the traction unit and the axial movement part, the sleeve part can be moved in parallel and the height of the sleeve part can be adjusted. When the sleeve part is sleeved on the patient's upper limb arm, the traction unit and the axial movement part can realize the active traction movement of the patient's upper limb arm, help the patient's upper limb arm to perform upper limb elevation rehabilitation training and upper limb horizontal extension rehabilitation training, reduce the degree of sequelae and other neurological deficits, improve the patient's self-care ability, promote the functional recovery of shoulder joint and arm muscles, improve the patient's self-care ability in daily life, help restore the range of motion and strength of shoulder joint, and prevent joint stiffness and muscle atrophy.

[0013] 2) This application has an airbag inside the sleeve. The volume of the airbag can be adjusted by the air supply unit (inflating the airbag to make the volume of the airbag larger or smaller). The change in the volume of the airbag can massage the patient's arm, which can further promote blood circulation, relieve muscle tension and pain, and improve the patient's comfort.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0021] Example:

[0022] Please see Figure 1-4 This application provides a technical solution: an upper limb rehabilitation nursing device for stroke patients, including a seat 1, an axially movable part 2 fixed to the outside of the seat 1, a bracket 3 fixed to the movable end of the axially movable part 2, two traction units 4 connected to one side of the bracket 3, two sleeve parts 6 located on the upper part of the seat 1 and used to be sleeved on the outside of the upper limb, and two sets of traction lines 5 respectively connecting the two sleeve parts 6 to the two traction units 4.

[0023] Please see Figure 1 and Figure 3 The sleeve part 6 includes a housing 61 with a hollow groove inside, two support rods 62 rotatably connected to the outside of the housing 61, and two traction holes 63 inside the two support rods 62. A set of traction lines 5 consists of two wires, one end of which is respectively attached to the traction holes 63 inside the two support rods 62. The housing 61 is used to sleeve the outside of the arm. When the axial moving part 2 drives the support 3 and the traction unit 4 to move axially, the traction unit 4 can drive the sleeve part 6 to move through the traction lines 5, thereby moving the arm resting on the armrest of the seat 1 and separating the arm from the armrest. During this process, the traction unit 4 can also retract the traction lines 5, thereby adjusting the height of the sleeve part 6. When both the X-axis position (horizontal position) and Z-axis position (height) of the sleeve part 6 change, the patient's arm can be moved to a horizontal position. If the patient's arm is to be moved and the upper limb is to be raised, each traction unit 4 needs to be... The two traction lines 5 on the housing 61 are pulled separately. First, the traction unit 4 pulls and coils the traction line 5 closer to the palm, and coils it more tightly. Then, the traction line 5 closer to the biceps brachii is coiled less tightly. That is, the length of the traction line 5 closer to the biceps brachii is greater than the length of the traction line 5 closer to the palm. This will cause the housing 61 to tilt. During the adjustment of the traction lines 5, the axial moving part 2 drives the support 3 to move, thereby enabling the patient's upper limb arm to move and change the upper limb arm from a horizontal position to an raised position. This helps to perform upper limb elevation rehabilitation training and upper limb horizontal extension rehabilitation training, reducing the degree of sequelae and other neurological deficits, improving the patient's self-care ability, promoting the functional recovery of the shoulder joint and arm muscles, improving the patient's daily living ability, helping to restore the range of motion and strength of the shoulder joint, and preventing joint stiffness and muscle atrophy.

[0024] Please see Figure 1 and Figure 3 An airbag 7 is fixedly attached to the inner wall of the hollow groove. Two air supply parts 8 for supplying gas to the airbag 7 are symmetrically fixed to both sides of the seat 1. The air supply part 8 is an air pump, which is connected to the airbag 7 through a pipe (the pipe connecting the air pump and the airbag 7 is not shown in the accompanying drawings of this application). Since the air pump, the pipe, and the inflation and deflation of the airbag 7 are all mature existing technologies, they will not be described in detail here. The two air supply parts 8 can respectively inflate and deflate the airbag 7 in the two housings 61, so that the volume of the airbag 7 changes, thereby massaging the patient's arm, which can further promote blood circulation, relieve muscle tension and pain, and improve the patient's comfort.

[0025] like Figure 1 as well as Figure 4 As shown, the traction unit 4 includes a housing 41 fixed to one side of the bracket 3, two traction rods 44 and two shafts 47 rotatably connected inside the housing 41, two gears 45 fixed to the outside of the two traction rods 44, two gears 46 fixed to one end of the two shafts 47 and meshing with the gears 45, and two servo motors 43 fixed to one side of the housing 41. The other ends of the two shafts 47 are rotatably connected to the inner wall of the housing 41. The output shafts of the two servo motors 43 pass through the housing 41 and are fixed to the gears 46. The other end of the traction line 5 passes inside the housing 41 and is wound around the outside of the traction rods 44. The two servo motors 43 can drive the gears 46 and the shafts 47 to rotate. The rotation of the gears 46 drives the two traction rods 44 to rotate through the gears 45. The rotation of the two traction rods 44 realizes the winding and unwinding of the traction line 5, thereby realizing the adjustment of the height and tilt of the housing 41.

[0026] like Figure 1 as well as Figure 4 As shown, two positioning gears 48 are fixedly connected to the outside of the two shafts 47, and two positioning sockets 49 are slidably connected inside the housing 41. Two electric push rods 42 are fixedly connected to both sides of the housing 41, and the telescopic ends of the two electric push rods 42 penetrate into the inside of the housing 41 and are fixedly connected to one end of the two positioning sockets 49 respectively. The other end of the positioning socket 49 is used to insert into two adjacent teeth on the outside of the positioning gear 48 to restrict the rotation of the positioning gear 48. When the electric push rod 42 extends and drives the positioning socket 49 to move, the positioning socket 49 can be inserted between two adjacent teeth on the outside of the positioning gear 48, thereby limiting the positioning gear 48 and the shafts 47, so that the shafts 47, the second gear 46, the first gear 45 and the traction rod 44 cannot rotate. This achieves the positioning of the traction line 5, which can help the patient perform long-term horizontal forward extension or upper limb lifting rehabilitation exercises.

[0027] like Figure 2As shown, the axial moving part 2 includes two bases 21 fixed to both sides of the seat 1, movable grooves 22 opened inside the two bases 21, two slides 31 respectively slidably connected in the two movable grooves 22, a guide rod 25 fixed in one of the movable grooves 22 and movably inserted in one of the slides 31, a lead screw 23 rotatably connected to the inner wall of the other movable groove 22 and screwed into the other slide 31, and a drive part 24 fixed to one side of one of the bases 21. The output shaft of the drive part 24 passes through the base 21 and is fixedly connected to one end of the lead screw 23. The upper ends of the two slides 31 are fixedly connected to the lower end of the bracket 3. The drive part 24 (a power drive unit composed of a motor, reducer, etc., which is mature existing technology and will not be described in detail here) drives the lead screw 23 to rotate. The rotation of the lead screw 23 can drive one of the slides 31 to move in the movable groove 22. The movement of one slide 31 drives the bracket 3 and the other slide 31 to move, thereby realizing the adjustment of the axial position of the bracket 3 and the sleeve part 6.
