Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a hand care exercise device for orthopedic injuries. Background Technology

[0002] Rehabilitation training is applicable to the post-traumatic care and treatment of bodily injuries caused by trauma. It uses appropriate, targeted, or specific physical movements to help the body or body parts return to a normal state. In orthopedics, after treatment for hand injuries, doctors often require patients to consciously exercise their hands appropriately to facilitate a faster recovery. However, in orthopedic patients with multiple finger fractures, multiple fingers often need to be bandaged together during treatment. Since the fingers are constantly in a closed position during treatment, it can lead to difficulty in opening the fingers after recovery. This can affect normal hand movement as the fingers gradually recover, thus impacting the patient's ability to use their hand normally after trauma recovery. In such cases, hand care and exercise devices are necessary.

[0003] However, most existing hand care exercise devices can only train patients' fingers to grasp. With only grasping training, the patient's hand recovery is slow. The wrist should be trained simultaneously. Moreover, the intensity of training for each finger is not precise enough, which cannot effectively help the subsequent recovery of patients with hand fractures, prolonging the recovery time and affecting the patient's normal life. Therefore, a hand care exercise device for orthopedic patients is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, which mostly only train the patient's fingers to grasp. This results in slow hand recovery due to grasping alone. The wrist should also be trained simultaneously. Furthermore, the intensity of training for each finger is not precisely adjusted, which fails to effectively aid the subsequent recovery of hand fracture patients, prolonging the recovery time and affecting their normal lives. Therefore, this invention proposes a hand care and exercise device for orthopedic patients.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A hand care exercise device for orthopedic injuries includes a support base. A mounting frame is fixedly connected to the top of the support base. Four adjusting seats are fixedly connected to the upper inner wall of the mounting frame. A threaded rod is rotatably connected inside each of the four adjusting seats. A movable seat is threadedly connected to the outer surface of each threaded rod. A first rotating connecting seat is fixedly connected to the bottom of the movable seat. A telescopic rod is fixedly connected to the bottom of the first rotating connecting seat. A training spring is sleeved on the outer surface of the telescopic rod. A second rotating seat is fixedly connected to the end of the telescopic rod away from the first rotating connecting seat. A connecting plate is fixedly connected to the bottom of the second rotating seat. A rotating seat is rotatably connected to the end of the connecting plate away from the second rotating connecting seat via a rotating rod. Finger sleeves are fixedly connected to the bottom of both the connecting plate and the rotating seat. A dual-axis motor is fixedly connected to the upper surface of the support seat. A shaft is fixedly connected to the output end of the dual-axis motor. A drive wheel is fixedly connected to the end of the shaft away from the dual-axis motor. A driven wheel is rotatably connected to the outer surface of the drive wheel via a belt. A drive shaft is fixedly connected to the outer wall of the driven wheel. A palm support plate is fixedly connected to the outer wall of the drive shaft. A control button is provided at the end of the palm support plate away from the drive shaft. A massage ball is fixedly installed on the top of the palm support plate.

[0006] Furthermore, the threaded rod extends through the inner wall of the adjusting seat to the outside at the end away from the mounting bracket and is fixedly connected to an adjusting knob.

[0007] Furthermore, each of the four adjustment seats has a moving groove on its lower surface. The moving seat is disposed inside the moving groove and is slidably connected to the adjustment seat. The moving groove guides the moving seat and limits its moving distance.

[0008] Furthermore, a rotating shaft is rotatably connected to the middle of the inner wall of the mounting bracket via a bearing. The rotating shaft passes through four rotating seats and is fixedly connected to the four rotating seats. The flexion and extension movement trajectory of the entire finger is guided by the rotating shaft and each rotating connecting seat.

[0009] Furthermore, both ends of the drive shaft pass through the inner wall of the mounting frame and are rotatably connected to the lower end of the inner wall of the mounting frame via bearings.

[0010] Furthermore, the top of the training spring is fixedly connected to the lower surface of the first rotating connecting seat, and the top of the training spring is fixedly connected to the upper surface of the second rotating connecting seat. Together with the telescopic rod 7, it creates resistance to the patient's fingers for grip training, and at the same time, the fingers are extended by the force of the training spring.

[0011] Furthermore, a fixed seat is fixedly connected to the outer wall of the support base on the side away from the palm support plate. An elastic band is fixedly installed on the outer wall of the fixed seat. The elastic band is designed to adapt to different arm circumferences, ensuring that the arm is stable and does not shift during training.

[0012] Furthermore, a protective pad is provided on the upper surface of the fixing base. Both the protective pad and the massage ball are made of silicone. The silicone protective pad on the upper surface of the fixing base effectively increases comfort and avoids compression of nerves and blood vessels.

[0013] Furthermore, a pressure sensor is provided on the inner wall of the finger sleeve, and a display is embedded and fixedly installed on the outer wall of the fixing base. The internal wiring connection and working principle of the pressure sensor and the display are existing technologies and will not be described in detail here.

[0014] Furthermore, the pressure sensor is electrically connected to the display, and the dual-axis motor is electrically connected to the control button. The control button controls the opening and closing of the dual-axis motor, causing the palm support plate to flip, while simultaneously lifting the patient's palm for wrist-flipping training.

[0015] The present invention has the following beneficial effects: 1. In this invention, the first rotating connecting seat, telescopic rod, training spring, second rotating connecting seat, rotating shaft, connecting plate, rotating seat and finger sleeve are used in combination to enable the patient to actively perform flexion and extension movements of the fingers. When the patient is performing grasping training, the patient can press the control button with their finger to rotate the dual-axis motor, shaft, active rotating wheel, driven rotating wheel, transmission shaft and palm support plate at a positive angle, dragging the patient's palm to perform wrist joint extension training, realizing the coordinated training of the patient's fingers and wrist, promoting the recovery of the patient's hand function and improving the training effect of the patient's hand.

[0016] 2. In this invention, the position of the first rotating connecting seat is adjusted by using the adjusting seat, adjusting knob, threaded rod and moving seat together, changing the direction of the telescopic rod and the pre-compression of the training spring. This allows the therapist to independently adjust the training intensity for each finger, precisely adjust the training intensity, and observe the grip strength of each finger in real time with the pressure sensor and display for adjustment. This avoids overtraining or undertraining of the fingers and greatly improves the scientificity and precision of hand rehabilitation training. Attached Figure Description

Detailed Implementation

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

[0020] Example 1 like Figure 1 - Figure 6 As shown, the present invention proposes a hand care exercise device for orthopedic trauma, comprising a support base 1, a mounting frame 2 fixedly connected to the top of the support base 1, four adjusting seats 3 fixedly connected to the upper inner wall of the mounting frame 2, threaded rods 4 rotatably connected inside the four adjusting seats 3, movable seats 5 threadedly connected to the outer surface of the threaded rods 4, a first rotating connecting seat 6 fixedly connected to the bottom of the movable seat 5, a telescopic rod 7 fixedly connected to the bottom of the first rotating connecting seat 6, a training spring 8 sleeved on the outer surface of the telescopic rod 7, a second rotating connecting seat 9 fixedly connected to the end of the telescopic rod 7 away from the first rotating connecting seat 6, a connecting plate 10 fixedly connected to the bottom of the second rotating connecting seat 9, and the connecting plate 10 being located away from the first rotating connecting seat 6. A rotating seat 11 is rotatably connected to one end of the rotating connecting seat 9 via a rotating rod. Finger sleeves 12 are fixedly connected to the bottom of both the connecting plate 10 and the rotating seat 11. A dual-axis motor 13 is fixedly connected to the upper surface of the support seat 1. A shaft 14 is fixedly connected to the output end of the dual-axis motor 13. An active rotating wheel 15 is fixedly connected to the end of the shaft 14 away from the dual-axis motor 13. A driven rotating wheel 16 is rotatably connected to the outer surface of the active rotating wheel 15 via a belt. A transmission shaft 17 is fixedly connected to the outer wall of the driven rotating wheel 16. A palm support plate 18 is fixedly connected to the outer wall of the transmission shaft 17. A control button 19 is provided at the end of the palm support plate 18 away from the transmission shaft 17. A massage ball 20 is fixedly installed on the top of the palm support plate 18.

[0021] The inner wall of the mounting bracket 2 is rotatably connected to a rotating shaft 22 via a bearing at the middle end. The rotating shaft 22 passes through four rotating seats 11 and is fixedly connected to the four rotating seats 11.

[0022] The two ends of the drive shaft 17 pass through the inner wall of the mounting bracket 2 and are rotatably connected to the lower end of the inner wall of the mounting bracket 2 via bearings.

[0023] The top of the training spring 8 is fixedly connected to the lower surface of the first rotating connecting seat 6, and the top of the training spring 8 is fixedly connected to the upper surface of the second rotating connecting seat 9.

[0024] A fixed seat 23 is fixedly connected to the outer wall of the support base 1 on the side away from the palm support plate 18, and an elastic band 24 is fixedly installed on the outer wall of the fixed seat 23.

[0025] The upper surface of the fixed base 23 is provided with a protective pad 25, and both the protective pad 25 and the massage ball 20 are made of silicone.

[0026] In this embodiment, the patient sits or stands and places their forearm on the fixation seat 23. The elastic band 24 on the outer wall of the fixation seat 23 is then used to secure the patient's forearm. The patient extends their fixed arm naturally forward, palm down, fingers naturally spread. The index, middle, ring, and little fingers are then passed through the finger sleeves 12 at the bottom of the connecting plate 10 and the rotating seat 11, respectively. When the patient exerts force with their fingers, they actively flex and extend their fingers. During finger flexion, the rotating shaft 22 drives the connecting plate 10 and the rotating seat 11 to rotate, causing the connecting plate 10 and the rotating seat 11 to move the finger sleeves 12 to grip, overcoming the resistance of the telescopic rod 7 and the training spring 8, thereby effectively exercising the strength and endurance of the finger flexor muscles. During finger extension, the training… The spring 8's rebound force assists in finger extension while simultaneously training the finger extensor muscles through eccentric contraction. While the patient is performing grasping exercises, pressing the control button 19 on the palm support plate 18 activates the dual-axis motor 13. The motor 13 outputs power to drive the shaft 14, which in turn rotates the active rotating wheel 15. This, via belt drive, causes the driven rotating wheel 16 and the drive shaft 17 to rotate, allowing the palm support plate 18, fixed to the drive shaft 17, to rotate and remain at any angle within the 0-90° range. This allows the palm support plate 18 to support the patient's palm, promoting wrist extension training and achieving comprehensive training of the coordinated range of motion of the finger and wrist joints. This efficiently promotes the recovery of the patient's hand function and enhances the effectiveness of hand exercises.

[0027] Example 2 like Figure 1 - Figure 6 As shown, based on Embodiment 1, the threaded rod 4 extends through the inner wall of the adjusting seat 3 to the outside and is fixedly connected to the adjusting knob 21 at the end away from the mounting bracket 2.

[0028] The lower surfaces of the four adjustment seats 3 are provided with moving grooves, and the moving seats 5 are set inside the moving grooves and slidably connected to the adjustment seats 3.

[0029] A pressure sensor 26 is provided on the inner wall of the finger sleeve 12, and a display 27 is embedded and fixedly installed on the outer wall of the fixing seat 23.

[0030] Pressure sensor 26 is electrically connected to display 27, and dual-axis motor 13 is electrically connected to control button 19.

[0031] In this embodiment, for patients at different rehabilitation stages, the therapist can independently adjust the training intensity of each finger by rotating four adjustment knobs 21. Rotating the adjustment knobs 21 drives the threaded rod 4 to rotate, causing the moving seat 5 to slide horizontally in the moving groove of the adjustment seat 3, thereby changing the initial position of the first rotating connecting seat 6, changing the direction of the telescopic rod 7 and the pre-compression of the training spring 8. The greater the pre-compression, the greater the spring resistance that the patient needs to overcome when flexing their fingers, and the higher the training intensity. In conjunction with the pressure sensor 26 inside the finger sleeve 12, the therapist can monitor and provide feedback on the patient's finger grip strength in real time through the display 27. The therapist can then customize the resistance for each finger to match its rehabilitation stage, accurately adjust the training intensity, avoid overtraining or undertraining, and greatly improve the scientific and precise nature of hand rehabilitation training. During the patient's rest period, the fingers can be actively rolled and massaged or squeezed on the silicone massage ball 20 on the top of the palm support plate 18 to relax them. The massage ball 20 can stimulate acupoints on the palm, promote local blood circulation, relieve muscle fatigue, and help restore proprioception and tactile sensation in the hand.

[0032] Working principle: The patient places their palm down and passes their fingers through the corresponding finger sleeves 12. The patient's forearm is then fixed to the fixing base 23 by the elastic band 24. The patient actively exerts force to flex their fingers, overcoming the resistance of the telescopic rod 7 and the training spring 8, to perform grasping training. The therapist observes the patient's finger grip strength feedback on the monitor 27 and adjusts the training intensity of each finger by rotating the adjustment knob 21. After completing one grasping training session, the patient presses the control button 19 with their finger to move the palm support plate 18 to perform wrist joint extension training. The patient's fingers and wrist joints are trained alternately. Finally, during the rest period after training, the patient can promote local blood circulation and relieve muscle fatigue by rolling or squeezing the massage ball 20.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
