Description

Technical Field

[0001] This utility model belongs to the field of rehabilitation equipment technology, and in particular relates to a grip strength training device. Background Technology

[0002] Postoperative conditions in cardiology patients, such as after heart surgery, may include stiffness in the shoulder joint and surrounding tissues. Clinically, patients are usually required to perform upper limb exercises to promote blood circulation in the upper limbs, reduce numbness in the arm, and enhance myocardial contractility. Similarly, after coronary intervention, patients may experience swelling in the upper limbs. Clinically, patients are usually required to perform finger exercises, such as the commonly used "finger exercises," to promote local blood circulation and metabolism, improve tissue edema, and reduce swelling.

[0003] While finger exercises can train the fingers, they lack appeal and are difficult for patients to maintain. Furthermore, the intensity of finger exercises is limited, and as patients progress through rehabilitation, they can no longer meet the required training intensity. Therefore, it is necessary to propose a grip strength trainer for finger training to enhance its appeal and meet the demands of finger training intensity. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a grip strength trainer that enhances the fun of finger training and meets the intensity requirements of finger training.

[0005] This utility model is achieved through the following technical solution:

[0006] A grip strength trainer includes a three-way tube, specifically, the three-way tube is a T-shaped three-way tube; both the left and right ends of the three-way tube are provided with connectors, and each connector is provided with a flow channel hole that runs through from left to right;

[0007] Each connector has a grip sleeve at the end furthest from the tee tube. The grip sleeve is hollow, and the end furthest from the connector is closed. The inside of the grip sleeve is connected to the inside of the tee tube through a flow channel hole. The grip sleeve is made of soft rubber material and can deform under force. When filling liquid is injected into the tee tube from the top interface, the filling liquid flows into the grip sleeve through the flow channel hole to fill the grip sleeve. When the grip sleeve is squeezed, the filling liquid inside the grip sleeve can be squeezed out through the flow channel hole.

[0008] The top end of the T-tube is threaded with a sealing cap. After filling the T-tube and the two grip sleeves with filling liquid, the sealing cap can be used to seal the top end of the T-tube to prevent the filling liquid from leaking out. If the T-tube is not filled with filling liquid, a closed space is formed inside the T-tube. When you squeeze the grip sleeve with your hand, you need to apply a certain amount of force to squeeze out the filling liquid inside the grip sleeve, thereby achieving the purpose of finger training.

[0009] Each connector has a mounting hole on its outer side wall, which intersects the flow channel hole in a cross shape. The central axis of the mounting hole is coplanar with the central axis of the flow channel hole. The inner side wall of the mounting hole has an internal thread, and a screw is connected to the internal thread of the mounting hole. The screw can be used to adjust the flow area of ​​the flow channel hole, thereby adjusting the grip strength. When the flow area of ​​the flow channel hole is small, it requires greater resistance to squeeze the grip sleeve to expel the filling liquid from the flow channel hole. When the flow area of ​​the flow channel hole is large, it is relatively easier to squeeze the grip sleeve to expel the filling liquid from the flow channel hole.

[0010] Furthermore, the grip sleeve includes a connecting tube, an end, and a soft rubber sleeve disposed between the connecting tube and the end. The soft rubber sleeve is made of soft rubber material, including silicone, rubber, TPU, TPE, or soft PVC, etc. One end of the soft rubber sleeve is fixedly connected to the connecting tube, and the other end is fixedly connected to the end. It can be bonded or injection molded. The connecting tube has a hollow structure, and the interior of the connecting tube communicates with the interior of the soft rubber sleeve. The end seals one end of the soft rubber sleeve.

[0011] Furthermore, the outer wall of the soft rubber sleeve is provided with several anti-slip protrusions, which provide an anti-slip function when the patient holds the soft rubber sleeve with their hand.

[0012] Furthermore, one end of the connector is threaded to the interface of the tee pipe, and the other end of the connector is threaded to the connecting pipe; the threaded connection between the connector and the tee pipe and between the connector and the connecting pipe facilitates disassembly and assembly, and facilitates cleaning and maintenance of each component after disassembly. If a component is damaged, it can also be replaced individually, saving costs.

[0013] Furthermore, a support rod is inserted inside the soft rubber sleeve, and a bracket for fixing the support rod is provided inside the connecting tube. One end of the support rod is fixedly connected to the bracket, and the other end is fixedly connected to the end. The connecting tube, the end, and the support rod are coaxial. The support rod connects the end to the connecting tube together, which helps to maintain the shape of the grip sleeve and makes it easier for the patient to grip the soft rubber sleeve with their hand.

[0014] Furthermore, the tee, connector, and connecting pipe are all made of transparent materials, such as transparent plastic or transparent glass, which facilitates observation of the internal filling liquid.

[0015] Furthermore, the diameter of the mounting hole is not less than the diameter of the flow channel hole, so that the screw installed in the mounting hole can completely block the flow channel hole.

[0016] Furthermore, the screw includes a threaded shaft and a cylindrical nut, the outer wall of which is provided with anti-slip grooves to facilitate screwing.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] Postoperative cardiology patients can use this grip strength trainer for upper limb training to promote blood circulation in the upper limbs, enhance myocardial contractility, improve upper limb tissue edema, reduce swelling, and promote patient recovery. When using the grip strength trainer for finger grip strength training, turn the screw to maximize the flow area of ​​the flow channel orifice. Filling fluid is then injected into the three-way tube through the top interface. The filling fluid in the three-way tube flows into the grip sleeves through the flow channel orifice on the connector. Both grip sleeves are filled with filling fluid, and the three-way tube is also filled with filling fluid. Fill the tube completely, and install a sealing cap at the top of the T-connector to seal it, creating a closed space inside the T-connector. Adjust the flow area of ​​the flow channel hole by turning the screw. When patients use the grip strength trainer for upper limb training, they hold two grip sleeves with each hand and squeeze them alternately. Because the flow area of ​​the flow channel hole is small, there is some resistance when squeezing the grip sleeves, thus achieving the purpose of finger training. Using this grip strength trainer can enhance the fun of finger training, adjust the intensity of finger training, and meet the needs of finger training intensity. Attached Figure Description

[0023] A grip strength trainer, such as Figure 1 As shown, the device includes a T-shaped tee pipe 1. Specifically, the tee pipe 1 is a T-shaped tee pipe. Both the left and right ends of the tee pipe 1 are provided with connectors 2. Each connector 2 has a through-hole 9. The outer side wall of each connector 2 has a mounting hole 10. The mounting hole 10 and the through-hole 9 are arranged in a cross shape. The central axis of the mounting hole 10 is coplanar with the central axis of the through-hole 9. The inner side wall of the mounting hole 10 has an internal thread. A screw 4 is connected to the internal thread of the mounting hole 10. The screw 4 can be used to adjust the flow area of ​​the through-hole 9. The diameter of the mounting hole 10 is not less than the diameter of the through-hole 9, so that the screw 4 installed in the mounting hole 10 can completely block the through-hole 9.

[0024] Each connector 2 has a gripping sleeve 3 at the end furthest from the tee tube 1. The gripping sleeve 3 includes a connecting tube 3.1, an end 3.3, and a soft rubber sleeve 3.2 positioned between the connecting tube 3.1 and the end 3.3. The soft rubber sleeve 3.2 is made of soft rubber material, such as silicone, rubber, TPU, TPE, or soft PVC. The soft rubber sleeve 3.2 can deform under stress. One end of the soft rubber sleeve 3.2 is fixedly connected to the connecting tube 3.1, and the other end is fixedly connected to the end 3.3. It can be bonded or injection molded. The connecting tube 3.1 has a hollow structure. The interior of the connector 3.1 is connected to the interior of the soft rubber sleeve 3.2, and the interior of the connecting pipe 3.1 is connected to the interior of the tee pipe 1 through the flow channel hole 9. The end 3.3 seals one end of the soft rubber sleeve 3.2, making the grip sleeve 3 a hollow structure with one end closed. When the filling liquid 11 is injected into the interior of the tee pipe 1 from the top interface, the filling liquid 11 flows into the grip sleeve 3 through the flow channel hole 9 in the tee pipe 1 to fill the grip sleeve 3. When the soft rubber sleeve 3.2 is squeezed, some of the filling liquid 11 in the grip sleeve 3 can be squeezed out from the flow channel hole 9.

[0025] One end of connector 2 is threaded to the interface of tee pipe 1, and the other end of connector 2 is threaded to connecting pipe 3.1. Specifically, the outer side walls of the left and right interfaces of tee pipe 1 and the outer side wall of one end of connecting pipe 3.1 are all provided with external threads, and both ends of connector 2 are provided with internal threaded holes. The threaded connection between connector 2 and tee pipe 1 and between connector 2 and connecting pipe 3.1 facilitates disassembly and assembly. After disassembly, it is easy to clean and maintain each component. If a component is damaged, it can be replaced individually, saving costs.

[0026] The soft rubber sleeve 3.2 has a support rod 7 installed inside. The connecting tube 3.1 has a bracket 6 for fixing the support rod 7 inside. One end of the support rod 7 is fixedly connected to the bracket 6, and the other end is fixedly connected to the end 3.3. Specifically, the support rod 7 and the bracket 6, as well as the support rod 7 and the end 3.3, can be welded or threaded. The connecting tube 3.1, the end 3.3, and the support rod 7 are coaxial. The support rod 7 connects the end 3.3 and the connecting tube 3.1 together, which helps to maintain the shape of the grip sleeve 3 and makes it easier for the patient to grip the soft rubber sleeve 3.2. Specifically, the bracket 6 is in the shape of a circular steering wheel. The bracket 6 has an inner ring and an outer ring. The inner ring and the outer ring are connected by multiple connecting rods. The outer ring is fixed to the inner wall of the connecting tube 3.1. The support rod 7 is fixedly connected to the inner ring. There is a flow channel between the outer ring and the inner ring for the filling liquid 11 to flow through. The connection structure between the support rod 7 and the bracket 6 is like the connection structure between a car steering column and a circular steering wheel.

[0027] A sealing cap 5 is threaded onto the top interface of the three-way tube 1. After filling liquid 11 into the three-way tube 1 and the two grip sleeves 3, the sealing cap 5 can be used to seal the top interface of the three-way tube 1 to prevent leakage of the filling liquid 11. If the three-way tube 1 is not filled with filling liquid 11, a closed space is formed inside the three-way tube 1. When you squeeze the grip sleeve 3 with your hand, you need to apply a certain amount of force to squeeze out the filling liquid 11 inside the grip sleeve 3, thereby achieving the purpose of finger training.

[0028] Preferably, in this embodiment, such as Figure 1 As shown, the outer wall of the soft rubber sleeve 3.2 is provided with several anti-slip protrusions 8. When the patient holds the soft rubber sleeve 3.2 with his / her hand, the anti-slip protrusions 8 have an anti-slip function.

[0029] Preferably, in this embodiment, the three-way pipe 1, the connector 2, and the connecting pipe 3.1 are all made of transparent materials, such as transparent plastic or transparent glass, which facilitates observation of the internal filling liquid 11.

[0030] Preferably, in this embodiment, such as Figure 1 As shown, the screw 4 includes a threaded shaft and a columnar nut. The outer wall of the columnar nut has anti-slip grooves to facilitate the turning of the screw 4.

[0031] The method of using the grip strength trainer and its technical effects in this embodiment are as follows:

[0032] This grip strength trainer is an assembled structure. When assembling and using it, such as... Figure 1 As shown, a connecting pipe 3.1 is threaded to both the left and right ends of the tee pipe 1, making it easy to disassemble and assemble. After disassembly, it is convenient to clean and maintain each component. If a component is damaged, it can be replaced individually, saving costs.

[0033] After assembly, turn screw 4 to adjust the flow area of ​​flow channel hole 9 to the maximum. Fill the T-tube 1 with filling liquid 11 through the top interface of T-tube 1. Tap water can be used as filling liquid 11. The filling liquid 11 in T-tube 1 flows into grip sleeve 3 through flow channel hole 9 on connector 2. Both grip sleeves 3 are filled with filling liquid 11. T-tube 1 is filled with filling liquid 11 but not completely filled. Install sealing cap 5 at the top interface of T-tube 1 to seal it, so that a closed space is formed inside T-tube 1.

[0034] The assembly process of the grip strength trainer is completed by medical staff or family members and then used by the patient. Medical staff or family members can adjust the flow area of ​​the flow channel hole 9 by turning the screw 4 to adjust the resistance when squeezing the filling liquid 11 in the grip sleeve 3. The patient can use the grip strength trainer to train the upper limbs while lying in bed or sitting on a stool, which is quite convenient.

[0035] The initial state of the grip strength trainer before use is as follows Figure 2As shown, when the patient uses the grip strength trainer for upper limb training, each of their two hands holds one of the two soft rubber sleeves 3.2, and one hand squeezes one of the soft rubber sleeves 3.2. Figure 3 As shown, the soft rubber sleeve 3.2 deforms, and the filling liquid 11 inside the grip sleeve 3 is squeezed from the flow channel hole 9 into the three-way tube 1. Because the screw 4 blocks the flow channel hole 9, the flow area of ​​the flow channel hole 9 is small, so there is a certain resistance when squeezing the soft rubber sleeve 3.2, thus achieving the purpose of training the fingers of the hand. After the patient releases one hand, their other hand squeezes another soft rubber sleeve 3.2, which deforms, and the filling liquid 11 inside the grip sleeve 3 is squeezed from the flow channel hole 9 into the three-way tube 1. It can also help the other grip sleeve 3 that was previously squeezed to refill with the filling liquid 11. Similarly, because the screw 4 blocks the flow channel hole 9, there is a certain resistance when squeezing the soft rubber sleeve 3. The flow area of ​​the flow channel hole 9 is relatively small, so there is a certain resistance when squeezing the soft rubber sleeve 3.2, which achieves the purpose of training the fingers of the hand. The two hands are trained alternately. The patient can also turn the screw 4 to adjust the flow area of ​​the flow channel hole 9. When the flow area of ​​the flow channel hole 9 is small, it requires greater resistance to squeeze the grip sleeve 3 to squeeze the filling liquid 11 inside the grip sleeve 3 out of the flow channel hole 9. When the flow area of ​​the flow channel hole 9 is large, it is relatively easier to squeeze the filling liquid 11 inside the grip sleeve 3 out of the flow channel hole 9. This can be used to adjust the resistance and training intensity during grip training.

[0036] Finger training is performed by squeezing water out of the grip sleeve 3. The structure consisting of the grip sleeve 3 and the connector 2 is similar to filling a mineral water bottle with water and making a hole in the cap. When you squeeze the bottle body with your hand, the water inside the bottle can be squeezed out through the hole in the cap. Because the hole is small, there is resistance when squeezing the bottle body. The greater the force, the faster the water is squeezed out. The larger the hole in the cap, the easier it is to squeeze water out.

[0037] Postoperative use of this grip strength trainer for upper limb training in cardiology patients can promote blood circulation in the upper limbs, enhance myocardial contractility, improve upper limb tissue edema, reduce swelling, and promote patient recovery. Using this grip strength trainer can enhance the fun of finger training, adjust the intensity of finger training, and meet the needs of finger training intensity.
