DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0022] As Figures 1 to 5 shown, the utility model provides a multifunctional handgrip for hemodialysis patients, including device housing 1, the front of device housing 1 is installed with closure plate 11, the inside middle of device housing 1 is fixedly connected with fixed frame 3, the middle of the top of fixed frame 3 is installed with counter 301, the top of the right side of device housing 1 is installed with display panel 2, the middle of the bottom of fixed frame 3 is movably sleeved with threaded column 302, the outside of threaded column 302 is screwedly sleeved with threaded pipe 303, the bottom of threaded pipe 303 is fixedly connected with bottom plate 104, the both sides of the top of bottom plate 104 are fixedly connected with positioning rod 305, positioning rod 305 is movably sleeved with device housing 1, the top of the outside of threaded column 302 is fixedly connected with handle rod 304, the bottom of the front of closure plate 11 is fixedly connected with thumb ring 105, thumb ring 105 is rubber material, the both sides of the top of device housing 1 are movably sleeved with movable rod 101, the top of movable rod 101 is fixedly connected with pressing plate 102, the top of pressing plate 102 is fixedly connected with finger ring 103, finger ring 103 is rubber material.
[0023] In the embodiment of the present application, the distance between the pressing plate 102 and the bottom plate 104 can be adjusted according to the size of the user's palm. When the handle rod 304 is rotated clockwise, the threaded tube 303 moves downward along the outside of the threaded column 302 under the threaded thrust of the threaded column 302, thereby pushing the bottom plate 104 to move downward, and then the distance between the pressing plate 102 and the bottom plate 104 becomes larger, so that the device is suitable for use by people with larger palms. When the handle rod 304 is rotated counterclockwise, the bottom plate 104 is moved upward by the threaded tube 303, so that the distance between the pressing plate 102 and the bottom plate 104 becomes smaller, so that the device is suitable for use by people with smaller palms.
[0024] The spring force of the device can be adjusted according to the size of the user's palm force. The limiting block 107 can position the pressing plate 102. In the absence of external force, the distance between the pressing plate 102 and the bottom plate 104 remains unchanged. When the threaded block 108 is rotated clockwise, the threaded block 108 moves downward along the outside of the movable rod 101, and then the spring 109 is compressed, thereby increasing the grip force required by the user when pressing. When the threaded block 108 is rotated counterclockwise, the spring 109 is elongated, thereby reducing the grip force required by the user when pressing.
[0025] When using the device, the thumb passes through the thumb ring 105 and the four fingers pass through the finger ring 103 to prevent the device from falling out of the hand. When pressing, the pressing plate 102 pushes the pressing rod 106 to move to the inside of the device housing 1 and contacts the counter 301. Each contact increases the value on the electronic display screen 201, thereby counting the number of presses and better planning according to the user's condition.
[0026] The bottom right side of the display panel 2 is provided with an electronic display screen 201, and the bottom right side of the display panel 2 is provided with a zero reset button 202. The display panel 2 and the counter 301 are electrically connected through wires.
[0027] The electronic display screen 201 can count the number of times the pressing rod 106 contacts the counter 301, thereby counting the number of presses by the user and facilitating the development of a pressing plan according to the user's physical condition. The zero reset button 202 can clear the numbers on the electronic display screen 201.
[0028] The outside of the movable rod 101 is fixedly sleeved with a limiting block 107, the outside of the movable rod 101 is threadedly sleeved with a threaded block 108, the outside of the movable rod 101 is provided with a spring 109, the movable rod 101 is movably sleeved with the top of the fixed frame 3, and the spring 109 is located between the threaded block 108 and the top of the fixed frame 3.
[0029] By rotating the threaded block 108, the distance between the threaded block 108 and the top of the fixed frame 3 can be adjusted, thereby adjusting the amount of compression of the spring 109, and then adjusting the required grip strength for pressing.
[0030] The middle of the bottom of the pressing plate 102 is fixedly connected with a pressing rod 106, and the pressing rod 106 is located in the same vertical direction as the counter 301.
[0031] After the user presses to the position, the pressing rod 106 contacts the top of the counter 301, and after the contact, the counter 301 sends a signal to the display panel 2, and the value of the electronic display screen 201 is increased by one, so that the number of times of pressing of the patient is counted.
[0032] The working principle and use process of the utility model are as follows:
[0033] According to the size of the palm of the user, the distance between the pressing plate 102 and the bottom plate 104 can be adjusted, the handle rod 304 is rotated clockwise, under the threaded thrust of the threaded column 302, the threaded pipe 303 moves downwards along the outside of the threaded column 302, thereby pushing the bottom plate 104 to move downwards, and then the distance between the pressing plate 102 and the bottom plate 104 is increased, so that the device is suitable for use by people with larger palms, and the handle rod 304 is rotated counterclockwise, so that the bottom plate 104 is driven upwards by the threaded pipe 303, and the distance between the pressing plate 102 and the bottom plate 104 is reduced, so that the device is suitable for use by people with smaller palms.
[0034] According to the size of the palm strength of the user, the elasticity of the device can be adjusted, the limiting block 107 can play a positioning role on the pressing plate 102, and in the absence of external force, the distance between the pressing plate 102 and the bottom plate 104 remains unchanged, the threaded block 108 is rotated clockwise, the threaded block 108 moves downwards along the outside of the movable rod 101, and then the spring 109 is compressed, thereby increasing the required grip strength when the user presses, and the threaded block 108 is rotated counterclockwise, and then the spring 109 is elongated, thereby reducing the required grip strength when the user presses.
[0035] When using the device, the thumb passes through the thumb ring 105, and the four fingers pass through the finger ring 103, so that the device is prevented from falling off the hand, when pressing, the pressing plate 102 pushes the pressing rod 106 to move to the inside of the device shell 1 and contacts the counter 301, and the value on the electronic display screen 201 is increased by one each time, so that the number of times of pressing is counted, and the user's condition can be better formulated.
