Description

Technical Field

[0001] This utility model relates to medical devices, specifically a grip strength trainer for preschool children. Background Technology

[0002] The recovery rate of upper limb fractures in preschool children is relatively fast. When evaluating the rehabilitation effect at each stage, it is mainly based on visual inspection and questioning, lacking clear assessment data. Collecting grip strength data can objectively and accurately evaluate the rehabilitation effect of upper limb fractures in preschool children. However, preschool children have small grip strength and limited cognitive abilities, and there are currently no grip strength devices suitable for preschool children on the market. Utility Model Content

[0003] In response to the problems pointed out in the background art, the purpose of this utility model is to provide a grip strength device for preschool children, which solves the problem of rehabilitation evaluation after upper limb fractures in preschool children, and can also be used as a rehabilitation exercise for preschool children to improve rehabilitation effects.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A preschool child grip strength trainer includes a head, a grip bar, and a pressure sensor. The head has a built-in controller connected to a power source, a counting display, and a voice module. The upper end of the grip bar is connected to the head, and the pressure sensor is disposed on the side surface of the grip bar and connected to the controller. The head is covered with a first flexible outer cover, and the grip bar and pressure sensor are covered with a second flexible outer cover. The first and second flexible outer covers are integrated to form a cartoon-style outer cover.

[0006] The controller is connected to a reset switch, which is located on the meter head.

[0007] The lower end of the grip is connected to a battery box, the power supply is built into the battery box, and a third flexible outer cover is fitted over the battery box. The third flexible outer cover is integrated with the second flexible outer cover.

[0008] The third flexible outer cover has a protrusion on its side.

[0009] The grip is a hollow tube structure, and the battery box is a cylindrical shell structure. The battery box is threadedly connected to the grip.

[0010] The meter head is a circular shell structure, with the counting display screen embedded on the surface of the meter head and the voice module located inside the meter head; a window is provided on the first flexible outer cover, and the window corresponds to the position of the counting display screen.

[0011] The lower part of the second flexible outer cover has a flexible annular boss.

[0012] The beneficial effects of this invention are as follows: This invention adopts a single-bar structure, suitable for preschool children to grasp. The flexible outer cover with a cartoon design increases gripping comfort and attracts children's attention. It displays and accurately counts the corresponding grip strength value each time the child grasps the grip, while the voice module plays encouraging voice messages, making the grip strengthener more fun for children. This invention can provide objective data for the rehabilitation evaluation of preschool children with upper limb fractures and can be used as a rehabilitation exercise tool to improve rehabilitation outcomes.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-3 As shown, this utility model provides a grip strength trainer for preschool children, including a head unit 1, a grip bar 2, and a pressure sensor 3. The head unit has a built-in controller 4, which is connected to a power supply 5, a counting display screen 6, and a voice module 7. The upper end of the grip bar 2 is connected to the head unit 1, and the pressure sensor 3 is disposed on the side surface of the grip bar 2 and connected to the controller 4. The head unit 1 is covered with a first flexible outer cover 8, and the grip bar 2 and the pressure sensor 3 are covered with a second flexible outer cover 9. The first flexible outer cover 8 and the second flexible outer cover 9 are integrated to form a cartoon-style outer cover. In the above structure, the controller 4 is powered by the power supply 5, and the counting display screen 6 and the voice module 7 are both powered and controlled by the controller 4. The structure, connection, and control architecture of the controller 4, the counting display screen 6, and the voice module 7 are all existing technologies. The controller 4 can be a micro-programmable controller or a microcontroller.

[0020] Specifically, since preschool children have small hands and their grip strength is limited to no more than 10 kg, this invention adopts a single-bar structure to facilitate their grasping. The pressure sensor 3 is a rectangular plate-shaped pressure sensor with dimensions of 75×12.7 mm and a maximum load capacity of 10 kg. The structure of the pressure sensor 3 is based on existing technology, with its base fixedly attached to the side surface of the grip bar 2, and the working surface (or multiple measuring points) facing outwards. This structural design solves the problem of grip strength testing for preschool children. The cartoon cover is made of single or multiple layers of flexible material in a cartoon shape. In one embodiment of this invention, the outermost layer of the cartoon cover is made of removable and washable cartoon cotton fabric to improve grip comfort. The cartoon shape attracts children's attention and increases interactive fun.

[0021] The controller 4 is connected to a reset switch 10, which is mounted on the meter head 1. Correspondingly, a first window is provided on the first flexible outer cover 8, and a second window corresponds to the position of the reset switch 10, exposing the reset switch. Specifically, the controller 4 has a built-in reset circuit or reset module, and the reset switch is connected to the reset circuit or reset module of the controller 4. When the reset switch switches, the controller 4 performs reset control according to the current or voltage variable. This part of the control principle is also existing technology and will not be described in detail.

[0022] The lower end of the grip 2 is connected to a battery box 11, the power supply 5 is built into the battery box 11, and a third flexible cover 12 is fitted on the outside of the battery box 11. The third flexible cover 12 is integrated with the second flexible cover 9.

[0023] The third flexible outer cover 12 has a flexible protrusion 13 on its side. The flexible protrusion 13 is not easy for young children to grasp, so that the grasping target of young children is concentrated on the grip bar 2.

[0024] The grip 2 is a hollow tube structure, and the battery box 11 is a cylindrical shell structure. The battery box 11 is threadedly connected to the grip 2. Specifically, the power supply 5 and the controller 4 are electrically connected via wires, which are guided through the axial inner hole of the grip 2.

[0025] The meter head 1 is a circular shell structure, with the counting display screen 6 embedded on its surface and the voice module 7 located inside. A second window is provided on the first flexible outer cover 8, corresponding to the position of the counting display screen 6. Correspondingly, multiple small holes (not shown) are provided on the meter head 1 at the position corresponding to the voice module to prevent unclear speech when the voice module plays audio.

[0026] The second flexible outer cover 9 has a flexible annular protrusion 14 at the bottom. The flexible annular protrusion 14 is also not easy for young children to grasp, so that the young children's grasping target is concentrated on the part of the grip 2 where the pressure sensor 3 is installed.

[0027] The control principle of this utility model is as follows: Figure 4 As shown, each time a child grasps, pressure sensor 3 collects pressure data and transmits it to controller 4. Controller 4 receives the pressure data and controls the counting display screen 6 to display the corresponding grip strength value and number of times. Simultaneously, controller 4 also controls voice module 7 to announce the number of times or to provide encouraging words such as "Go baby, you're great!" to increase interaction with the child. The reset switch 10 on the meter 1 is a button. When the data from pressure sensor 2 is unstable, the controller can be reset via reset switch 10. At this time, the counting display screen 6 and voice module 7 will reset to zero and recalculate the count.

[0028] The parts of this utility model not described in detail are existing technologies.
