Description

Technical Field

[0001] This utility model belongs to the field of medical rehabilitation technology, specifically relating to a multifunctional elastic device for training. Background Technology

[0002] The rehabilitation period for patients with functional impairments is generally long, relying heavily on in-hospital rehabilitation. However, for various reasons, in-hospital rehabilitation treatment often fails to cover the entire treatment cycle. Furthermore, many patients experience poor recovery after discharge. This is because in-hospital rehabilitation is led by therapists who create customized, scientific, and detailed training plans, allowing patients to focus their rehabilitation efforts purposefully and specifically. Discharge disrupts these plans, and patients, separated from their therapists, often engage in aimless self-training. While therapists can develop home training plans for discharged patients, most struggle to follow them diligently. Furthermore, the lack of professional guidance often compromises the details of training movements, significantly reducing the effectiveness of home training. Another reason is that while in-hospital rehabilitation allows patients to utilize various professional rehabilitation devices, taught to use them by therapists, these devices are often expensive and have limited functionality. Consequently, many patients lack access to these devices after discharge and are forced to rely on manual exercises. However, manual exercises are often monotonous, lacking interactivity and entertainment, which can lead to negative psychological outcomes.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0019] To address the issues of monotonous and tedious home training programs for patients with functional impairments, especially those undergoing self-training and home rehabilitation, resulting in poor functional recovery after discharge, this application provides a multifunctional training device that combines initiative, entertainment, and affordability. Figure 1-2As shown, a multifunctional training elastic device includes an outer ball 1 and an inner ball 4, both made of rubber. The outer ball 1 can deform under external pressure and automatically return to its original shape after the pressure is released. The inner ball 4 is disposed inside the outer ball 1, with its outer wall tangentially fixed to the inner wall of the outer ball 1. The outer ball 1 and the inner ball 4 have a diameter difference, thus forming a crescent-shaped rebound area between the outer wall of the inner ball 4 away from the tangent point and the inner wall of the outer ball 1 when the inner ball 4 and the outer ball 1 are tangent. This crescent-shaped rebound area has a certain gap, which allows for the adjustment of the outer ball 4's shape after pressing. During the process, the air in the crescent-shaped rebound area is first squeezed. When the outer ball 1 and the inner ball 4 come into contact, the subsequent squeezing force acts on the inner ball 4, and the elasticity of the inner ball 4 provides feedback to the user, thereby achieving the purpose of multi-stage exercise. Furthermore, the outer ball 1 is equipped with an air whistle 5 corresponding to the crescent-shaped rebound area. The main body of the air whistle 5 is a plastic tube with a diameter of 5mm. It has a whistle inside. The outer ball 1 has a corresponding mounting hole for the air whistle 5. The length of the air whistle 5 is adapted to the thickness of the outer ball 1. One end of the air whistle 5 extends to the outer wall of the outer ball 1, and the other end extends to the crescent-shaped rebound area. When the outer ball 1 is squeezed, the crescent-shaped rebound area undergoes compressive deformation, the gas in the internal space is squeezed, the airflow is discharged through the air whistle 5, and the airflow drives the internal whistle to produce sound. This addresses the issue of self-training at home for patients with motor dysfunction and some patients with superficial and deep sensory impairments after discharge from the hospital. In particular, for patients with Brunnstrom stage III and above, it provides a training device that integrates entertainment and training, emphasizing high initiative, strong interactivity, and multifunctionality.

[0020] In one optional embodiment, the elastic sphere assembly can be divided into small, medium, and large sizes, with a diameter of 10-15cm. The diameter difference between the inner sphere 4 and the outer sphere 1 is 1-5cm, for example, the outer sphere 1 has a diameter of 10cm and the inner sphere 4 has a diameter of 7cm; the outer sphere 1 has a diameter of 10cm and the inner sphere 4 has a diameter of 9cm; the outer sphere 1 has a diameter of 10cm and the inner sphere 4 has a diameter of 5cm.

[0021] The outer ball 1 is made of elastic material, specifically using safe, non-toxic, environmentally friendly, and easily deformable TPR (thermoplastic rubber) or TPE (thermoplastic elastomer) material. An air valve 6 is provided at the connection between the inner ball 4 and the outer ball 1. The air valve 6 is a plastic valve with a diameter of 7mm. The air valve 6 is located on the outer wall of the gas rebound zone of the device, and its length is adapted to the sum of the wall thicknesses of the outer ball 1 and the inner ball 4. The air valve 6 passes through the outer ball 1 and connects with the inner ball 4. The air valve 6 has a self-closing sealing core inside. When inflation is needed, the ball needle passes through the air valve 6 and extends into the inner ball 4 to inflate the inner ball 4. For details, refer to the basketball inflation valve 6. The inner sphere 4 and outer sphere 1 are made of translucent or transparent material. Inside the inner sphere 4 is a lighting component 7, which includes multiple colored LEDs powered by a button battery. A vibration trigger mechanism is incorporated, which electrically connects the button battery and LEDs, causing the LEDs to flash red, yellow, and white alternately for 5 seconds before turning off, until the next vibration trigger. Furthermore, this lighting component 7 is located within an embedded hollow sphere and is not fixed in place.

[0022] In an optional embodiment, the outer sphere 1 is provided with a connecting groove 8, which is used to detachably connect to the connecting rope 2. One end of the connecting rope 2 is detachably connected to the groove 8 via a plug, and the other end is connected to the annular elastic wristband 3. The connecting rope 2 is 1.5m long, made of elastic material, and can be stretched up to 2m. The plug is shaped like a cone with a height of 10mm and a diameter of 7mm. There is a semi-circular vertical ring with a diameter of 5mm on the bottom surface of the cone. The connecting rope 2 is connected to the semi-circular vertical ring by a knot connection.

[0023] A gasket is provided on the inner side of the outer ball 1 to locally thicken the area. The gasket is fixed by adhesive or integrally formed with the outer ball 1. This is used to set the connecting groove 8 to avoid insufficient wall thickness of the outer ball 1 due to the setting of the connecting groove 8. Specifically, the gasket is made of elastic rubber of the same material as the outer ball 1. The connecting groove 8 is opened at the corresponding position on the outer ball 1. The inner cavity of the connecting groove 8 corresponds to the plug. The opening of the groove is reduced to half the diameter of the plug to limit the position after the plug is inserted. The plug is made of the same material as the outer ball 1 and the gasket. The plug is inserted into the ball rope connection point groove of the device. Pressing it inward will embed it into the groove, and pulling it outward will remove the plug.

[0024] The circular elastic wristband 3 is made of the same material as the connecting rope 2, and has a circular structure with a diameter of 7cm and a width of 5cm.

[0025] In an optional embodiment, the outer ball 1 and the inner ball 4 are fixed by adhesive bonding. The fixed contact surface of the outer ball 1 and the inner ball 4 is a circle concentric with the air nozzle 6, and the diameter of the contact area of ​​the circle is larger than the diameter of the air nozzle 6, thereby ensuring the stable installation of the air nozzle 6.

[0026] The outer sphere 1 has multiple equally divided areas on its outer wall. The outer hollow sphere is a random color among red, yellow, and blue. The surface is divided into 8 areas. In any two adjacent areas, one area is provided with uniformly distributed frosted particles 101, and the other area is provided with uniformly distributed dot-shaped protrusions 102, so that different areas of the outer sphere 1 have different tactile sensations.

[0027] Furthermore, the outer wall of the outer ball 1 is provided with a concave area 9 that fits the palm. The concave area 9 is hand-shaped and located on the side away from the connection of the inner ball 4, so that the crescent-shaped rebound area inside can be fully squeezed during the pressing process, ensuring that the internal gas is discharged through the air whistle 5.

[0028] This device can be used for sensory training, grasping training, balance training, coordination training, and agility training. Examples of training programs are given below.

[0029] Sensory training: This training program is suitable for patients with sensory dysfunction. The device is placed close to the skin of the affected area and rolled or brushed with pressure.

[0030] Grasping training: This training program is suitable for strengthening hand gripping strength. The affected hand is placed in the hand-shaped indentation on the surface of the device, and the patient grips it forcefully. This causes deformation in the gas rebound area of ​​the device, and the gas in the crescent-shaped space inside the device is compressed, producing a sound through the whistle 5. The goal of the training is for the patient to make the device produce a sound with each movement, thereby increasing the fun of the grasping training.

[0031] Passing training is a training program suitable for patients with balance disorders. The patient sits or stands, and the assistant stands in front of the patient and passes the device to the patient from different directions, so that the patient can actively shift their center of gravity and catch the device.

[0032] The ball-throwing and catching training program is suitable for patients with coordination disorders. The patient sits or stands, and the assistant throws the device to the patient from different directions. The patient actively catches the device. The difficulty of the training increases with the distance of the throw.

[0033] Dodgeball training is a training program mainly used for agility training. The patient sits or stands, and the assistant throws the device at the patient, who is asked to dodge it. The assistant can retrieve the device using the connecting rope 2. The training difficulty increases with the speed of the ball being thrown.

[0034] 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 shall be within the scope of protection of the pending claims of the present utility model.
