Description

Technical Field

[0001] This utility model relates to the field of postoperative rehabilitation assistive devices, specifically a grip ball. Background Technology

[0002] A grip ball is a medical rehabilitation device (such as...) Figure 4 As shown in the image, breast cancer patients often need to use a grip ball for postoperative rehabilitation. Appropriate grip ball exercises can improve venous blood circulation in the affected upper limb, prevent venous thrombosis, reduce soreness and pain in the affected limb, promote the recovery of limb function, and accelerate the overall recovery process. In addition, grip ball exercises can also promote lymphatic drainage, preventing or reducing complications such as lymphedema and axillary network syndrome.

[0003] Grip ball exercises are not only suitable for functional training of breast cancer patients after surgery, but also for reducing upper limb swelling in other areas. Although grip balls are widely used, the grip strength of traditional grip balls cannot be set specifically for them. Patients have difficulty consciously controlling their grip strength when gripping the ball. If too much force is used, it can easily lead to fatigue or soreness in the affected limb, increasing the risk of complications. If too little force is used, effective rehabilitation will not be achieved. Utility Model Content

[0004] The purpose of this invention is to provide a grip ball that solves the aforementioned problems in the prior art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A grip ball includes a sphere, with mounting plates sealed and fixedly installed on both sides of the sphere, and a mounting tube fixedly installed between the two mounting plates. One of the mounting plates has a through hole. It also includes a rotating shaft that extends through the through hole into the mounting tube and is rotatably connected to the end of the mounting tube away from the through hole. The rotating shaft has two external threads with opposite directions located in the middle of the mounting tube, and each thread has a movable block threaded onto it. Connecting rods are hinged to the top and bottom of the two movable blocks. The two upper connecting rods and the two lower connecting rods pass through holes in the upper and lower side walls of the mounting tube and are respectively hinged to I-shaped plates. The ends of the two I-shaped plates away from the connecting rods are arc-shaped. Support plates are fixedly installed on the inner top and bottom walls of the sphere. T-shaped extrusion plates are fixedly installed on opposite sides of the two support plates, and the sides of the two extrusion plates facing the I-shaped plates are arc-shaped to match the I-shaped plates.

[0007] The beneficial effects of this invention are as follows: This method ensures that when the patient presses the ball, the inward deformation distance is uniform, making it easier to control the patient's pressure and preventing excessive force. Simultaneously, medical staff can adjust the positions of the two I-beams to set different grip pressure intensities according to the rehabilitation needs of different stages of the disease, allowing for gradual increases in grip strength to meet the rehabilitation requirements at different stages.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, multiple rings are fixedly installed on the outside of the sphere corresponding to the support plate.

[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: When in use, the patient's fingers can be inserted into the corresponding finger rings to ensure that the patient applies force to the ball from both sides of the two support plates; at the same time, the fingers can be effectively fixed on the ball, avoiding the ball from slipping off the patient's palm due to excessive hand sweat; and the finger rings on the ball make the ball an irregular shape, which can prevent the ball from rolling and slipping off when placed on the bed.

[0011] Furthermore, a pressure sensor is fixedly installed on the side surface of the extrusion plate facing the I-beam plate, and a display screen is embedded on the outer surface of another mounting plate. The display screen integrates a controller, and the pressure sensor is electrically connected to the controller.

[0012] The beneficial effects of adopting the above-mentioned further solution are as follows: when the I-shaped plate contacts the extrusion plate, it indicates that the gripping pressure has been successfully applied once. At this time, the pressure sensor is triggered, the controller collects the number of times the pressure sensor is triggered, and displays the number on the display screen. This is used to automatically record the number of times the patient grips the pressure, so as to remind the patient whether the frequency of each rehabilitation exercise has met the standard.

[0013] Furthermore, multiple light-emitting modules are fixedly mounted on the surface of the mounting tube, and the light-emitting modules are electrically connected to the controller.

[0014] The beneficial effect of adopting the above-mentioned further solution is that when the grip pressure is successfully applied, the controller drives the light-emitting module to light up, reminding the patient and medical staff that the grip pressure is appropriate and the grip pressure is up to standard.

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] Example 1

[0023] like Figure 1 and Figure 2 As shown, a grip ball includes a ball 1, with mounting plates 2 sealed and fixedly installed on both sides of the ball 1, and a mounting tube 3 fixedly installed between the two mounting plates 2. One mounting plate 2 has a through hole 201. It also includes a rotating shaft 4, which extends through the through hole 201 into the mounting tube 3 and is rotatably connected to the end of the mounting tube 3 away from the through hole 201. The rotating shaft 4 is provided with two external threads with opposite thread directions in the middle of the interior of the mounting tube 3, and each is threaded with a moving block 6. The top and bottom of the two moving blocks 6 are hinged with connecting rods 7. The two upper connecting rods 7 and the two lower connecting rods 7 respectively pass through the through holes on the upper and lower side walls of the mounting tube 3 and are respectively hinged with I-shaped plates 8. The ends of the two I-shaped plates 8 away from the connecting rods 7 are arc-shaped. Support plates 9 are fixedly installed on the inner top wall and inner bottom wall of the ball 1. T-shaped extrusion plates 10 are fixedly installed on the opposite side surface of the two support plates 9. The side of the two extrusion plates 10 facing the I-shaped plates 8 is arc-shaped and matches the I-shaped plates 8.

[0024] When patients use this device in the early stages of rehabilitation, medical staff rotate the shaft 4, causing the two moving blocks 6 to move towards each other. This, in turn, moves the two I-shaped plates 8 away from the mounting tube 3 via the connecting rod 7, adjusting the distance between the I-shaped plates 8 and the compression plate 10. When the patient grips the ball 1, the ball 1 moves the compression plate 10 downwards via the support plate 9. When the compression plate 10 and the I-shaped plate 8 come into contact, the patient senses that the ball 1 cannot be pressed further and stops pressing. This method ensures that the distance the ball 1 deforms inwards is consistent, facilitating control of the patient's pressure and preventing excessive force. Furthermore, medical staff can adjust the position of the two I-shaped plates 8 to set different grip pressure levels according to the rehabilitation needs of different stages of the disease, allowing for gradual increases in grip strength to meet the rehabilitation requirements at each stage.

[0025] In practice, a rocker arm 5 is provided at one end of the rotating shaft 4 located outside the sphere 1; and the support plate 9 is made of polypropylene, which gives the support plate 9 a certain deformation capability.

[0026] Example 2

[0027] like Figure 2 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0028] Sliding grooves are provided on the inner walls of both sides of the mounting tube 3. A slider 601 is fixedly installed on both sides of the two moving blocks 6, with one end extending into the inside of the sliding groove and slidingly connected to the inner wall of the sliding groove. The slider 601 and the sliding groove limit the movement of the moving blocks 6, ensuring the stability of the two moving blocks 6 during lateral movement.

[0029] Example 3

[0030] like Figure 1 and Figure 2 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0031] Multiple finger rings 14 are fixedly installed on the outside of the sphere 1 corresponding to the support plate 9. In use, the patient's fingers can be inserted into the corresponding finger rings 14 to ensure that the patient applies force to the sphere from both sides of the two support plates 9. At the same time, it can effectively fix the fingers on the sphere 1, preventing the sphere 1 from detaching from the patient's palm due to excessive hand sweat. Furthermore, the finger rings 14 on the sphere 1 make the sphere an irregular shape, which can prevent the sphere 1 from rolling and slipping off when placed on the bed.

[0032] Example 4

[0033] like Figure 2 and Figure 2 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0034] A pressure sensor 11 is fixedly mounted on the surface of the compression plate 10 facing the I-shaped plate 8. A display screen 12 is embedded on the outer surface of another mounting plate 2, and the display screen 12 integrates a controller. The pressure sensor 11 is electrically connected to the controller. When the I-shaped plate 8 contacts the compression plate 10, it indicates a successful grip. At this time, the pressure sensor 11 is triggered. The controller collects the number of times the pressure sensor 11 is triggered and displays the number on the display screen 12 to automatically record the number of grips by the patient, so as to remind the patient whether the frequency of each rehabilitation exercise has reached the standard. In specific implementation, pressure sensors 11 are set on both the upper and lower compression plates 10. When both pressure sensors 11 are triggered at the same time, it indicates a successful grip, and the count on the display screen 12 increases by one. Multiple light-emitting modules 13 are fixedly mounted on the surface of the mounting tube 3, and the light-emitting modules 13 are electrically connected to the controller. When a successful grip is achieved, the controller drives the light-emitting modules 13 to light up, reminding the patient and medical staff that the grip pressure is appropriate and the grip pressure has reached the standard. In the specific setup, the mounting tube 3 contains a storage battery (not shown in the attached diagram) to provide power to the display screen 12 and the light-emitting module 13. At the same time, a charging interface is provided on the mounting plate 2, which is away from the crank handle 5, to facilitate charging of the storage battery.

[0035] The sphere 1 is made of thermoplastic copolyester. This not only gives the sphere 1 high elasticity, enabling it to move the support plate 9 and the extrusion plate 10 back to their original positions, but also gives the sphere 1 a certain degree of light transmittance, allowing the light emitted by the light-emitting module 13 to pass through the sphere 1.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
