[0005] To achieve the above objectives, this utility model provides a postoperative hand training pressure ball, comprising an ellipsoid, the ellipsoid being a hollow ellipsoidal structure. A four-point positioning plate and a thumb positioning plate are mounted on the outer side of the ellipsoid. The four-point positioning plate has four positioning holes, and the thumb positioning plate has one positioning hole. A finger sleeve is installed in each positioning hole. A fixing plate is installed inside the ellipsoid. A battery compartment is installed on the side of the fixing plate. Four fixing cylinders are installed on the top of the fixing plate. Springs are installed inside each of the four fixing cylinders. The top end of each spring extends to the outer side of the top of the fixing cylinder and connects to the inner wall of the top of the ellipsoid. A pressure sensor is installed at the bottom end of each spring.
[0006] Preferably, the ellipsoid is made of silicone material, and the finger sleeve is made of silicone material.
[0007] Preferably, the outer wall of the ellipsoid is provided with anti-slip texture.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] This invention provides a postoperative hand training pressure ball, such as... Figures 1-3 As shown, the device includes an ellipsoid 1, which is a hollow ellipsoidal structure. A four-point positioning plate 2 and a thumb positioning plate 3 are installed on the outer side of the ellipsoid 1. The four-point positioning plate 2 has four positioning holes, and the thumb positioning plate 3 has one positioning hole. A finger sleeve 4 is installed in each positioning hole. A fixing plate 11 is installed inside the ellipsoid 1. A battery compartment 17 is installed on the side of the fixing plate 11 to provide power to the sensor. Four fixing cylinders 12 are installed on the top of the fixing plate 11. A spring 13 is installed inside each of the four fixing cylinders 12. The top end of each spring 13 extends to the outer side of the top of the fixing cylinder 12 and is connected to the inner wall of the top of the ellipsoid 1. A pressure sensor 18 is installed at the bottom end of each spring 13.
[0025] In use, the ellipsoid 1 has a hollow internal structure, providing a suitable grip shape for training. A four-finger positioning plate 2 and a thumb positioning plate 3 are mounted on the outer side of the ellipsoid 1. The four-finger positioning plate 2 has four positioning holes, and the thumb positioning plate 3 has one positioning hole. This design ensures that the user's fingers can be accurately and stably positioned on the corresponding finger sleeves during training, thereby improving the targeting and effectiveness of the training. Furthermore, the design of the spring 13 and the pressure sensor 18 constitutes an adjustable pressure training mechanism. When the user squeezes the ellipsoid 1, the spring 13 is compressed, generating a reaction force to provide appropriate training resistance. Simultaneously, the pressure sensor 18 can sense and measure the pressure applied by the user in real time, providing objective data support for evaluating the training effect. This digitally labeled structural design not only makes hand training more scientific and reasonable but also allows for personalized training by adjusting the stiffness of the spring 13 or the setting of the pressure sensor 18 according to the user's rehabilitation status and training needs, helping to promote postoperative hand functional recovery.
[0026] In this embodiment, both the ellipsoid 1 and the finger sleeve 4 are made of silicone. Silicone material possesses excellent flexibility and durability, allowing the ellipsoid 1 and finger sleeve 4 to comfortably conform to the user's hand during use, while also being less prone to breakage. This material choice enhances the comfort and lifespan of the trainer.
[0027] Specifically, the outer wall of the ellipsoid 1 is fitted with anti-slip texture 6. The design of the anti-slip texture 6 increases the friction of the outer wall of the ellipsoid 1, making it more stable for the user to hold and squeeze the ellipsoid 1, and less prone to slipping. This improves safety and stability during training.
[0028] Furthermore, a zipper 5 is installed on one side of the ellipsoid 1. The zipper 5 allows the internal structure of the ellipsoid 1 to be easily opened and closed, facilitating the replacement or repair of internal components such as the fixing plate 11 and spring 13. This design improves the maintainability and practicality of the trainer.
[0029] Furthermore, limit rings 41 are installed at both ends of the finger sleeve 4, with the two limit rings 41 located on the outer sides of the positioning hole respectively. The design of the limit rings 41 can prevent the finger sleeve 4 from coming out of the positioning hole during long-term use, ensuring the stability and reliability of the finger sleeve 4, which improves the user experience and durability of the trainer.
[0030] Furthermore, brackets 14 are installed on both sides of the bottom of the fixing plate 11, and the bottom ends of the two brackets 14 are respectively connected and fixed to the inner walls of the bottom sides of the ellipsoid 1. The design of the brackets 14 provides stable support for the fixing plate 11, ensuring that the fixing plate 11 is firmly installed inside the ellipsoid 1. This structure improves the overall stability and durability of the trainer.
[0031] Furthermore, a water reservoir 15 is installed at the bottom of the fixing plate 11, and an inflation head 16 is installed at the bottom of the water reservoir 15. The bottom of the inflation head 16 extends through to the outer bottom of the ellipsoid 1. The design of the water reservoir 15 and the inflation head 16 allows the trainer to adjust its weight or stiffness as needed. By filling or defilling the water reservoir 15 with water, the overall feel of the ellipsoid 1 can be changed. This design increases the versatility and adaptability of the trainer.
[0032] Furthermore, a wireless transmission module 19 is installed on the outside of the bracket 14. The wireless transmission module 19 is electrically connected to the pressure sensor 18 via a line, and is used for wireless connection with external devices. The design of the wireless transmission module 19 allows the data measured by the pressure sensor 18 to be wirelessly transmitted to external devices, such as mobile phones or computers, in real time, making it convenient for users to view and analyze the training effect at any time. This design improves the intelligence and convenience of the trainer.
[0033] When using this postoperative hand training pressure ball, the user first inserts their thumb through the positioning hole of the thumb positioning plate 3 and their four fingers through the four positioning holes of the four-finger positioning plate 2. Each positioning hole is fitted with a finger sleeve 4 to ensure accurate and stable positioning of the fingers on the corresponding finger sleeve. The ellipsoid 1 and finger sleeves 4, made of silicone material, have good flexibility and durability, comfortably conforming to the user's hand and improving training comfort.
[0034] When the user squeezes the ellipsoid 1, the ellipsoid 1 deforms, the spring 13 is compressed, and a reaction force is generated, providing the user with appropriate training resistance. The stiffness of the spring 13 can be adjusted according to the user's rehabilitation progress and training needs to adapt to different stages of training.
[0035] The pressure sensor 18 at the bottom of the spring 13 can sense and measure the pressure applied by the user in real time. The wireless transmission module 19 mounted on the outside of the bracket 14 is electrically connected to the pressure sensor 18, and transmits the measured data wirelessly to external devices, such as mobile phones or computers, in real time.
[0036] Operating Procedure: The user places their finger into the corresponding finger sleeve 4, ensuring the finger is stably positioned on the trainer. The user then begins to squeeze the ellipsoid 1, causing it to deform and compressing the internal spring 13, generating a reaction force. The user can gradually increase or decrease the squeezing force according to training needs at different stages. The pressure sensor 18 senses and measures the pressure applied by the user in real time. The wireless transmission module 19 transmits the measured data to an external device in real time, allowing the user to view and analyze the training effect at any time.
[0037] Users can personalize their training by adjusting the stiffness of spring 13 or the settings of pressure sensor 18 according to their rehabilitation progress and training needs. By filling or emptying water into the water reservoir 15, users can also adjust the weight or stiffness of the trainer, change the overall feel of the ellipsoid 1, and increase the diversity and adaptability of training.
[0038] Finally, it should be noted that the electronic components in the wireless transmission module 19 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires. The specific connection method should refer to the working order between each electrical component in the above working principle to complete the electrical connection. All of these are technologies known in the art.
