Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to an upper limb chest expansion rehabilitation device. Background Technology

[0002] Patients who are bedridden for extended periods often experience limited upper limb movement, which can lead to muscle atrophy and negatively impact their daily lives after discharge. Therefore, once their condition stabilizes, appropriate, targeted, or specific physical exercises are necessary to help their bodies return to a normal state.

[0003] Chest expansion exercises are commonly used to strengthen patients' cardiopulmonary function, promote blood circulation in the heart, and help them recover their health as soon as possible.

However, currently available rehabilitation equipment has the following drawbacks:

[0047] like Figure 1-11 The upper limb chest expansion rehabilitation device shown includes:

[0048] The lifting device 1 includes a telescopic component and a motion component 14. The telescopic component includes a telescopic arm 11, a first motion arm 12, and a second motion arm 13. The first motion arm 12 and the second motion arm 13 are respectively disposed on both sides of the telescopic arm 11. The first motion arm 12 and the second motion arm 13 are rotatably connected to the telescopic arm 11. The motion component 14 is connected to the first motion arm 12 and the second motion arm 13 respectively, driving the first motion arm 12 and the second motion arm 13 to rotate on both sides of the telescopic arm 11, thereby driving the patient's arm movement to complete the chest expansion exercise.

[0049] Control component 2 includes a control unit (not shown in the figure) and a heart rate monitoring unit (not shown in the figure). The heart rate monitoring unit monitors the patient's heart rate. The control unit controls the movement frequency of the motion component 14 based on the measurement results of the heart rate monitoring unit. The control unit adjusts the lengths of the telescopic arm 11, the first motion arm 12, and the second motion arm 13 according to the patient's CT images to adapt to the patient's arm length and shoulder width, allowing the patient to perform rehabilitation training in a standard posture during exercise, fully exercising the patient's cardiopulmonary strength, promoting blood circulation in the heart, and helping the patient recover their health as soon as possible. The heart rate monitoring unit measures the patient's heart rate in real time and adjusts the speed of the motion component 14 according to the patient's heart rate, increasing the movement speed when the patient's heart rate is low and decreasing the movement speed when the patient's heart rate is high, ensuring the exercise effect while preventing the patient's heart rate from becoming too fast and causing danger.

[0050] The fixing component 4, the lifting device 1, and the control component 2 are all mounted on the bottom support 3. In some embodiments of this application, pulleys are provided at the bottom of the bottom support 3, and the number of pulleys is a natural number greater than 2. Optionally, the number of pulleys is 4.

[0051] Specifically, four casters are installed at the bottom of the bottom bracket 3, located at the corners of the bottom bracket 3.

[0052] Alternatively, two directional wheels and two omnidirectional wheels can be installed at the bottom of the bottom bracket 3.

[0053] The motion component 14 drives the first motion arm 12 and the second motion arm 13 to move, and the first motion arm 12 and the second motion arm 13 are connected to the patient's arms. Under the adjustment of the control unit, the lengths of the first motion arm 12 and the second motion arm 13 are the same as or similar to the length of the patient's arms, and the length of the telescopic arm 11 is the same as or similar to the length of the patient's shoulder, so that the patient's arms move synchronously with the first motion arm 12 and the second motion arm 13. When the first motion arm 12 and the second motion arm 13 are aligned, the patient's arms are open and level with their shoulders. When the first motion arm 12 and the second motion arm 13 are lowered, the patient's arms hang down and are close to their sides.

[0054] Specifically, the lifting device 1 also includes a motion support 15, and the telescopic arm 11, the first motion arm 12, and the second motion arm 13 are all located on the top of the motion support 15.

[0055] like Figure 1-9 As shown, the first moving arm 12 includes a first telescopic unit 121; the first telescopic unit 121 is connected to the control component 2, and the control component 2 adjusts the length of the first telescopic unit 121. By controlling and adjusting the length of the first telescopic unit 121, the overall length of the first moving arm 12 can be adjusted so that the length of the first moving arm 12 is the same as or similar to the length of the patient's left arm.

[0056] The first telescopic unit 121 includes a first telescopic motor A1 and a first telescopic rod A5; the first telescopic rod A5 is connected to the first telescopic motor A1, and the first telescopic motor A1 pushes the first telescopic rod A5 to perform reciprocating linear motion, so that the control component 2 adjusts the length of the first moving arm 12 through the first telescopic motor A1.

[0057] Specifically, such as Figure 10 As shown, the first telescopic unit 121 also includes a first driving wheel A2, a first driven wheel A3, a first rotating cavity A4, and a second telescopic cavity A6; the first telescopic motor A1, the first driving wheel A2, the first driven wheel A3, and the first rotating cavity A4 are all disposed inside the second telescopic cavity A6; the first driving wheel A2 is fixedly connected to the first telescopic motor A1, and the first driven wheel A3 is fixedly connected to the first rotating cavity A4; the first telescopic motor A1 drives the first rotating cavity A4 to rotate through the first driving wheel A2 and the first driven wheel A3; the first telescopic rod A5 is inserted into the second telescopic cavity A6 and then threadedly connected to the first rotating cavity A4.

[0058] The first driving wheel A2 is connected to the first driven wheel A3 via a belt, which enables the first telescopic motor A1 to drive the first rotating cavity A4 to rotate, so that the first telescopic rod A5 enters the first rotating cavity A4 or extends out of the first rotating cavity A4, thereby realizing the shortening and lengthening of the first telescopic unit 121.

[0059] A first directional structure (not shown in the figure) is provided on the inner wall of the second telescopic cavity A6, and a first directional groove is provided on the outer side wall of the first telescopic rod A5; the first directional structure engages with the first directional groove to prevent the first telescopic rod A5 from rotating synchronously with the first rotating cavity A4, so that the first telescopic rod A5 cannot perform the telescopic function.

[0060] In some embodiments of this application, the first telescopic unit 121 includes a first hydraulic cylinder (not shown in the figure), a first hydraulic pump (not shown in the figure), and a first liquid chamber (not shown in the figure); one end of the first hydraulic pump is connected to the first hydraulic cylinder through a conduit, and the other end is connected to the first liquid chamber. When the first hydraulic pump rotates forward, it pushes the liquid inside the first liquid chamber into the first hydraulic cylinder, causing the first hydraulic cylinder to extend, thereby extending the first moving arm 12. When the first hydraulic pump rotates in reverse, it pushes the liquid inside the first hydraulic cylinder into the first liquid chamber, causing the first hydraulic cylinder to contract, thereby shortening the first moving arm 12.

[0061] The control component 2 is connected to the first hydraulic pump via a wire; the control component 2 controls the operation of the first hydraulic pump, thereby enabling the control component 2 to adjust the length of the first moving arm 12.

[0062] like Figure 1-9 As shown, the first moving arm 12 also includes a first connecting structure 122, a first traction structure 123 and a first binding structure 124; one end of the first telescopic unit 121 is fixedly connected to the first connecting structure 122, and the other end is connected to the first binding structure 124 through the first traction structure 123; the side of the first connecting structure 122 away from the first telescopic unit 121 is rotatably connected to the telescopic arm 11, and the top of the first connecting structure 122 is connected to the moving component 14.

[0063] When in use, the first binding structure 124 is bound to the patient's left wrist. Under the control of the control component 2, the first moving arm 12 is the same or similar in length to the patient's left arm, so that the patient's left arm and the first moving arm 12 move synchronously.

[0064] The first moving arm 12 moves under the traction of the motion component 14. When the first moving arm 12 is horizontal, the patient's left arm is raised and level with the shoulder. When the first moving arm 12 is lowered, the patient's left arm hangs down and is close to the left side of the body.

[0065] like Figure 1-9 As shown, the second moving arm 13 includes a second telescopic unit 131; the second telescopic unit 131 is connected to the control component 2, and the control component 2 adjusts the length of the second telescopic unit 131. By controlling and adjusting the length of the second telescopic unit 131, the overall length of the second moving arm 13 can be adjusted so that the length of the second moving arm 13 is the same as or similar to the length of the patient's right arm.

[0066] The second telescopic unit 131 includes a second telescopic motor and a second telescopic rod; the second telescopic rod is connected to the second telescopic motor, and the second telescopic motor pushes the second telescopic rod to perform reciprocating linear motion, so that the control component 2 adjusts the length of the second moving arm 13 through the second telescopic motor.

[0067] Specifically, the second telescopic unit 131 has a similar structure to the first telescopic unit 121, as shown in the reference. Figure 10 As shown in the first telescopic unit 121, the second telescopic unit 131 further includes a second driving wheel (not shown in the figure), a second driven wheel (not shown in the figure), a second rotating cavity A4 (not shown in the figure), and a third telescopic cavity (not shown in the figure); the second telescopic motor, the second driving wheel, the second driven wheel, and the second rotating cavity A4 are all located inside the third telescopic cavity; the second driving wheel is fixedly connected to the second telescopic motor, and the second driven wheel is fixedly connected to the second rotating cavity A4; the second telescopic motor drives the second rotating cavity A4 to rotate through the second driving wheel and the second driven wheel; the second telescopic rod is inserted into the third telescopic cavity and then threadedly connected to the second rotating cavity A4.

[0068] The second driving wheel is connected to the second driven wheel via a belt, which enables the second telescopic motor to drive the second rotating cavity A4 to rotate, so that the second telescopic rod enters the second rotating cavity A4 or extends out of the second rotating cavity A4, thereby realizing the shortening and lengthening of the second telescopic unit 131.

[0069] A second directional structure (not shown in the figure) is provided on the inner wall of the third telescopic cavity, and a second directional groove is provided on the outer wall of the second telescopic rod; the second directional structure engages with the second directional groove to prevent the second telescopic rod from rotating synchronously with the second rotating cavity A4, thus preventing the second telescopic rod from performing its telescopic function.

[0070] In some embodiments of this application, the second telescopic unit 131 includes a second hydraulic cylinder (not shown in the figure), a second hydraulic pump (not shown in the figure), and a second liquid chamber (not shown in the figure); one end of the second hydraulic pump is connected to the second hydraulic cylinder through a conduit, and the other end is connected to the second liquid chamber. When the second hydraulic pump rotates forward, it pushes the liquid inside the second liquid chamber into the second hydraulic cylinder, causing the second hydraulic cylinder to extend, thereby extending the second moving arm 13. When the second hydraulic pump rotates in reverse, it pushes the liquid inside the second hydraulic cylinder into the second liquid chamber, causing the second hydraulic cylinder to contract, thereby shortening the second moving arm 13.

[0071] The control component 2 is connected to the second hydraulic pump via a wire; the control component 2 controls the operation of the second hydraulic pump, thereby enabling the control component 2 to adjust the length of the second moving arm 13.

[0072] like Figure 1-9As shown, the second motion arm 13 also includes a second connecting structure 132, a second traction structure 133 and a second binding structure 134; one end of the second telescopic unit 131 is fixedly connected to the second connecting structure 132, and the other end is connected to the second binding structure 134 through the second traction structure 133; the side of the second connecting structure 132 away from the second telescopic unit 131 is rotatably connected to the telescopic arm 11, and the top of the second connecting structure 132 is connected to the motion component 14.

[0073] When in use, the second binding structure 134 is bound to the patient's right wrist. Under the control of the control component 2, the second motion arm 13 is the same or similar in length to the patient's right arm, so that the patient's right arm and the second motion arm 13 move synchronously.

[0074] The second moving arm 13 moves under the traction of the motion component 14. When the second moving arm 13 is horizontal, the patient's right arm is raised and level with the shoulder. When the second moving arm 13 is lowered, the patient's right arm hangs down and rests against the right side of the body.

[0075] like Figure 1-9 As shown, the telescopic arm 11 includes a first telescopic cavity 111, a first telescopic column 112, and a second telescopic column 113; the first telescopic column 112 and the second telescopic column 113 are respectively inserted into the first telescopic cavity 111 from both sides; the first telescopic cavity 111 is connected to the pressure chamber 115 through a first conduit 114, and the side of the pressure chamber 115 away from the first conduit 114 is connected to the storage chamber 17 through a second conduit 116; one end of the telescopic motor is inserted into the interior of the pressure chamber;

[0076] The telescopic motor is connected to the control unit via wires, and the control unit controls the rotation of the telescopic motor. When the telescopic motor rotates forward, it pushes the liquid inside the storage chamber 17 into the first telescopic cavity 111 through the second conduit 116 and the first conduit 114, causing the first telescopic column 112 and the second telescopic column 113 to extend from the first telescopic cavity 111, thus extending the telescopic arm 11. When the telescopic motor rotates in reverse, it pushes the liquid inside the first telescopic cavity 111 into the storage chamber 17 through the first conduit 114 and the second conduit 116, causing the first telescopic column 112 and the second telescopic column 113 to retract into the first telescopic cavity 111, thus shortening the telescopic arm 11.

[0077] Specifically, a partition plate 101 is provided inside the first telescopic cavity 111, and the two are fixedly connected; the partition plate 101 divides the first telescopic cavity 111 into two equal parts. This allows the first telescopic column 112 and the second telescopic column 113 to extend or retract synchronously from the first telescopic cavity 111. This prevents the first moving arm 12 and the second moving arm 13 from not being able to maintain alignment when raised due to the first telescopic column 112 and the second telescopic column 113 not extending to the same length, thus preventing one of the patient's arms from being higher than the other.

[0078] In some embodiments of this application, the telescopic arm 11 includes a third telescopic unit (not shown in the figure) and a fourth telescopic unit (not shown in the figure); the third telescopic unit and the fourth telescopic unit are fixedly connected; the end of the third telescopic unit away from the fourth telescopic unit is rotatably connected to the first moving arm 12; and the end of the fourth telescopic unit away from the third telescopic unit is rotatably connected to the second moving arm 13.

[0079] The third and fourth telescopic units extend or shorten synchronously under the control of the control component 2, so that the first telescopic column 112 and the second telescopic column 113 extend to the same length at the same time.

[0080] Specifically, the third telescopic unit includes a third telescopic motor and a third telescopic rod; the third telescopic rod is connected to the third telescopic motor, and the third telescopic motor drives the third telescopic rod to perform reciprocating linear motion, so that the control component 2 adjusts the length of the third telescopic unit through the third telescopic motor.

[0081] Specifically, the third telescopic unit is structurally similar to the first telescopic unit 121, as shown in the reference. Figure 10 As shown in the first telescopic unit 121, the third telescopic unit also includes a third driving wheel (not shown in the figure), a third driven wheel (not shown in the figure), a third rotating cavity A4 (not shown in the figure), and a fourth telescopic cavity (not shown in the figure); the third telescopic motor, the third driving wheel, the third driven wheel, and the third rotating cavity A4 are all located inside the fourth telescopic cavity; the third driving wheel is fixedly connected to the third telescopic motor, and the third driven wheel is fixedly connected to the third rotating cavity A4; the third telescopic motor drives the third rotating cavity A4 to rotate through the third driving wheel and the third driven wheel; the third telescopic rod is inserted into the fourth telescopic cavity and then threadedly connected to the third rotating cavity A4.

[0082] The third driving wheel is connected to the third driven wheel via a belt, which enables the third telescopic motor to drive the third rotating cavity A4 to rotate, so that the third telescopic rod enters the third rotating cavity A4 or extends out of the third rotating cavity A4, thereby realizing the shortening and lengthening of the third telescopic unit.

[0083] A third directional structure (not shown in the figure) is provided on the inner wall of the fourth telescopic cavity, and a third directional groove is provided on the outer side wall of the third telescopic rod; the third directional structure engages with the third directional groove to prevent the third telescopic rod from rotating synchronously with the third rotating cavity A4, thus preventing the third telescopic rod from performing its telescopic function.

[0084] The fourth telescopic unit includes a fourth telescopic motor and a fourth telescopic rod; the fourth telescopic rod is connected to the fourth telescopic motor, and the fourth telescopic motor pushes the fourth telescopic rod to perform reciprocating linear motion, so that the control component 2 adjusts the length of the fourth telescopic unit through the fourth telescopic motor.

[0085] Specifically, the fourth telescopic unit is structurally similar to the first telescopic unit 121, as shown in the reference. Figure 10 As shown in the first telescopic unit 121, the fourth telescopic unit also includes a fourth driving wheel (not shown in the figure), a fourth driven wheel (not shown in the figure), a fourth rotating cavity A4 (not shown in the figure), and a fifth telescopic cavity (not shown in the figure); the fourth telescopic motor, the fourth driving wheel, the fourth driven wheel, and the fourth rotating cavity A4 are all located inside the fifth telescopic cavity; the fourth driving wheel is fixedly connected to the fourth telescopic motor, and the fourth driven wheel is fixedly connected to the fourth rotating cavity A4; the fourth telescopic motor drives the fourth rotating cavity A4 to rotate through the fourth driving wheel and the fourth driven wheel; the fourth telescopic rod is inserted into the fifth telescopic cavity and then threadedly connected to the fourth rotating cavity A4.
