Description

Technical Field

[0001] This utility model relates to the field of auxiliary chopsticks technology, and more specifically, to a training auxiliary chopstick. Background Technology

[0002] In the field of modern rehabilitation medicine, the rehabilitation treatment and quality of life improvement for hemiplegic patients have received much attention. For hemiplegic patients, achieving independent eating is not only the foundation for maintaining physiological needs, but also a crucial step in regaining confidence and promoting psychological rehabilitation. Currently, most chopstick assistive devices designed for hemiplegic patients rely on the patient's precise fingertip motor abilities, such as requiring the patient to achieve individual finger control or master complex lateral grasping movements. However, in the early rehabilitation stages of hemiplegic patients, fine motor functions of the hand are often severely impaired, making the aforementioned abilities difficult for them to achieve. This limits the practical use of existing assistive devices and fails to meet the needs of patients for independent eating and rehabilitation training.

[0003] Meanwhile, existing rehabilitation assistive devices typically separate eating from rehabilitation training, requiring patients to undergo specialized rehabilitation training at specific times and in specific environments, making it difficult to naturally integrate the rehabilitation process into daily life. This separate rehabilitation model not only increases the cost and time for patients but also reduces their motivation and persistence in rehabilitation training, hindering the recovery of hand function and the improvement of their quality of life.

[0004] Therefore, developing a chopsticks assistive device suitable for the early rehabilitation stage of hemiplegic patients, capable of utilizing the patient's remaining functional muscles, and convenient for rehabilitation training during daily meals has become an urgent problem to be solved. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model innovatively provides a training aid chopstick, which can solve the technical problem that the existing eating aids cannot meet the needs of hemiplegic patients.

[0006] To achieve the aforementioned technical objectives, this utility model discloses a training aid chopstick, comprising a first chopstick body, a second chopstick body, and a limiting member.

[0007] The limiting member includes a first limiting part, a second limiting part, and a third limiting part. The first limiting part and the second limiting part are connected through the third limiting part. The third limiting part is deformable, making the distance between the first limiting part and the second limiting part adjustable.

[0008] The first limiting part is fitted onto the first chopstick body, and the second limiting part is fitted onto the second chopstick body. The first limiting part and the second limiting part are located at the middle of the first chopstick body and the second chopstick body, biased towards the first end.

[0009] Furthermore, the third limiting part has a V-shaped structure, with its two ends connected to the first limiting part and the second limiting part, respectively.

[0010] Furthermore, the third limiting part is an elastic structure.

[0011] Furthermore, a finger sleeve is formed on the first limiting portion and / or the second limiting portion.

[0012] Furthermore, the first limiting part and the second limiting part are provided with limiting teeth, which are formed facing outwards of the first chopstick body and the second chopstick body, respectively.

[0013] Furthermore, the first limiting part and the second limiting part are curved, bending toward the first end of the first chopstick body and the second chopstick body.

[0014] Furthermore, the limiting member is detachably connected to the first chopstick body and the second chopstick body.

[0015] Furthermore, the training aid chopsticks also include a connector, which comprises a first connecting segment and a second connecting segment that are interconnected, and the first connecting segment and the second connecting segment are movable relative to each other.

[0016] The first connecting segment is connected to the first end of the first chopstick body, and the second connecting segment is connected to the first end of the second chopstick body.

[0017] Furthermore, the connector is a U-shaped or V-shaped integrated structure.

[0018] Furthermore, a first anti-slip block is formed at the second end of the first chopstick body, and a second anti-slip block is formed at the second end of the second chopstick body. Both the first and second anti-slip blocks are provided with anti-slip textures.

[0019] The first chopstick and the second chopstick use the first anti-slip block and the second anti-slip block to pick up food.

[0020] The beneficial effects of this utility model are as follows:

[0021] The training chopsticks provided by this utility model connect the first and second chopstick bodies via a limiting component. The first and second limiting parts of the limiting component form a limit with the fingers, and the third limiting part limits the area between the thumb and forefinger, preventing slippage during use. Suitable for use in the early rehabilitation stage of hemiplegic patients, this allows patients to receive rehabilitation training during daily meals, seamlessly integrating fine motor rehabilitation training into their daily lives. It not only improves the patients' quality of life but also enhances their self-esteem and reduces anxiety and depression. Attached Figure Description

[0029] The training aid chopsticks provided by this utility model will be explained and described in detail below with reference to the accompanying drawings.

[0030] The training chopsticks provided by this utility model connect the first chopstick body and the second chopstick body through a limiting member. The first and second limiting parts of the limiting member form a limit with the fingers, and the third limiting part limits the area between the thumb and forefinger, which can prevent slippage during use. It is suitable for use in the early rehabilitation stage of hemiplegic patients to assist hemiplegic or physically disabled individuals in easily using chopsticks for meals. At the same time, it provides an earlier opportunity for hand rehabilitation training, allowing patients to maximize muscle strength activation during the golden period. This not only improves the patient's quality of life but also enhances their self-esteem and reduces anxiety and depression. The following is a detailed description of this utility model in conjunction with specific implementation details:

[0031] In some embodiments, the present invention provides a training aid chopstick, such as Figure 1 As shown, it includes a first chopstick body 1, a second chopstick body 2, and a limiting member 3. The limiting member 3 is connected to the first chopstick body 1 and the second chopstick body 2. The first chopstick body 1 and the second chopstick body 2 can rotate relative to each other to achieve the action of picking up food. The limiting member 3 forms multiple limiting with the hand, which can play a role in preventing slippage.

[0032] The limiting component 3 includes a first limiting part 31, a second limiting part 32, and a third limiting part 33. The first limiting part 31 and the second limiting part 32 are connected by the third limiting part 33. The third limiting part 33 can deform to adjust the distance between the first limiting part 31 and the second limiting part 32. The first limiting part 31 is fitted onto the first chopstick body 1, and the second limiting part 32 is fitted onto the second chopstick body 2. The first limiting part 31 and the second limiting part 32 limit the fingers, for example, the thumb and the index finger, respectively. The first limiting part 31 and the second limiting part 32 are located in the middle of the first chopstick body 1 and the second chopstick body 2, biased towards the first end. In use, the first limiting part 31 and the second limiting part 32 limit the thumb and the index finger, respectively, and the third limiting part 33 rests against the web of the thumb and forefinger, forming a limiting position. The deformation of the third limiting part 33 can move the second ends of the first chopstick body 1 and the second chopstick body 2 closer together or further apart to hold or release food.

[0033] In some embodiments, the third limiting part 33 has a V-shaped structure, with its two ends connected to the first limiting part 31 and the second limiting part 32 respectively. Optionally, the third limiting part 33 is an elastic structure. In its natural state, the third limiting part 33 is in an open state, that is, the second ends of the first chopstick body 1 and the second chopstick body 2 are separated. When in use, force needs to be applied to the third limiting part 33 to overcome the elastic force of the third limiting part 33 and close the third limiting part 33, so that the second ends of the first chopstick body 1 and the second chopstick body 2 come closer to each other to hold the food. Then, after the external force is removed, the second ends of the first chopstick body 1 and the second chopstick body 2 can automatically separate under the action of the elastic force of the third limiting part 33 itself, making the operation of picking up food simpler. Patients who do not have fine motor function of the hand can use chopsticks by using only one muscle, reducing the difficulty of early rehabilitation training for patients. In addition, a certain grip strength is required to complete the gripping action, which can play a good role in exercising the thenar muscles of patients.

[0034] Furthermore, the limiting member 3 is an integral structure, that is, the first limiting part 31, the second limiting part 32, and the third limiting part 33 are an integral structure. For example, it can be integrally injection molded from silicone material, so that the limiting member 3 as a whole has a certain elasticity, thereby improving the comfort of operation. In other embodiments, the third limiting part 33 can also be deformed by means of, for example, a hinge. In this case, the third limiting part 33 can only play a limiting role to prevent the first chopstick body 1 and the second chopstick body 2 from slipping off.

[0035] In some embodiments, such as Figure 2 , Figure 3 As shown, finger sleeves are formed on the first limiting portion 31 and / or the second limiting portion 32. Optionally, both the first limiting portion 31 and the second limiting portion 32 include finger sleeves, which can be worn on the thumb and index finger respectively. Further, the first limiting portion 31 and the second limiting portion 32 are configured as symmetrical structures, thus satisfying both left-hand and right-hand use simultaneously. In other embodiments, the first limiting portion 31 and the second limiting portion 32 can be configured with different structures. For example, the first limiting portion 31 includes a finger ring that can be worn on the thumb, and the second limiting portion 32 is a limiting block that can cooperate with the index finger for limiting, in which case it is suitable for right-hand use. When left-hand use is required, the structures of the first limiting portion 31 and the second limiting portion 32 can be interchanged.

[0036] In some embodiments, such as Figure 4 , Figure 5 As shown, the first limiting part 31 and the second limiting part 32 are provided with limiting teeth, which are formed towards the outer side of the first chopstick body 1 and the second chopstick body 2, respectively. In this embodiment, the first limiting part 31 and the second limiting part 32 can be located under the thumb and index finger, respectively, which can restrict the first chopstick body 1 and the second chopstick body 2 from sliding up and down. Optionally, the first limiting part 31 and the second limiting part 32 are curved, curving towards the first end of the first chopstick body 1 and the second chopstick body 2, and a part of the thumb and index finger can be inserted into the concave structure formed by the curvature of the limiting teeth, which facilitates manual operation of opening the first chopstick body 1 and the second chopstick body 2. Optionally, in this embodiment, the limiting member 3 is made of elastic silicone material, preferably food-grade silicone material.

[0037] In some embodiments, the limiting member 3 is detachably connected to the first chopstick body 1 and the second chopstick body 2. Optionally, both the first limiting part 31 and the second limiting part 32 have through holes, and the first chopstick body 1 and the second chopstick body 2 pass through the through holes. Alternatively, slots are formed on the side walls of the first limiting part 31 and the second limiting part 32, and the first chopstick body 1 and the second chopstick body 2 are engaged in the slots. Alternatively, other detachable methods can be used to connect the first chopstick body 1 and the second chopstick body 2 to the limiting member 3. The detachable design of the limiting member 3 facilitates the replacement of the first chopstick body 1 and the second chopstick body 2 to suit different users, or it can be made suitable for children by replacing the first chopstick body 1 and the second chopstick body 2.

[0038] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the training aid chopsticks also include a connector 4. The connector 4 includes a first connecting segment 41 and a second connecting segment 42 that are connected to each other. The first connecting segment 41 and the second connecting segment 42 are movable relative to each other. The first connecting segment 41 is connected to the first end of the first chopstick body 1, and the second connecting segment 42 is connected to the first end of the second chopstick body 2. The connector 4 prevents the first chopstick body 1 and the second chopstick body 2 from sliding, which would cause the second ends of the first chopstick body 1 and the second chopstick body 2 to become misaligned and unable to properly pick up food.

[0039] In some embodiments, the connector 4 is a U-shaped or V-shaped integrated structure, that is, the first connecting segment 41 and the second connecting segment 42 are an integrated structure, and the two move relative to each other through elastic deformation. For example, it can be integrally injection molded from silicone and has a certain elasticity. It can cooperate with the third limiting part 33 of the limiting member 3 to provide elastic force, making the food gripping more stable. When in use, the first chopstick body 1 and the second chopstick body 2 will not cross. After gripping, it has an automatic rebound function. Even if the patient does not have fine motor function of the hand, he can easily use chopsticks by using only one muscle. In other embodiments, the first connecting segment 41 and the second connecting segment 42 of the connector 4 are hinged. In this case, it can only serve a connecting function. Alternatively, a torsion spring can be set at the hinge to provide elastic force.

[0040] The joint action of connector 4 and third limiting part 33 can also make the action of picking up food require greater force, so that connector 4 and third limiting part 33 can work together to adjust the grip force. For example, connector 4 can be omitted in early rehabilitation training. As the training time increases, connector 4 can be added to increase the grip force required to pick up food, forming gradient training.

[0041] In some embodiments, early rehabilitation training uses both connector 4 and limiter 3 to provide sufficient stability so that it can be used easily without any fine motor function of the hand muscles, allowing the patient to control the chopsticks with only one major muscle without worrying about the chopsticks falling off due to muscle weakness or hand tremors.

[0042] In the later stages of rehabilitation training, the limiting piece 3 can be removed while the connecting piece 4 is retained, increasing the difficulty of the training. The purpose is to train the fine motor function of the hand, as well as the muscle function of the fingertips, the control function of a single finger, and the grasping ability, until full recovery.

[0043] In some embodiments, such as Figure 2As shown, a first anti-slip block 11 is formed at the second end of the first chopstick body 1, and a second anti-slip block 21 is formed at the second end of the second chopstick body 2. Both the first anti-slip block 11 and the second anti-slip block 21 are provided with anti-slip textures to increase the contact area with food and make it easier to grip the food. The first chopstick body 1 and the second chopstick body 2 use the first anti-slip block 11 and the second anti-slip block 21 to grip the food. Optionally, the first anti-slip block 11 and the first chopstick body 1 are an integral structure, and the second anti-slip block 21 and the second chopstick body 2 are an integral structure. In other embodiments, the first anti-slip block 11 and the first chopstick body 1 are detachably connected, and the second anti-slip block 21 and the second chopstick body 2 are detachably connected, allowing for use with ordinary chopsticks. Further, the first anti-slip block 11 and the second anti-slip block 21 are made of food-grade silicone material, or use the same material as the first chopstick body 1 and the second chopstick body 2.
