The children grip strength detector that this embodiment provided is including holding a section of thick bamboo 2, gasbag 3, baroceptor (not shown in the figure) and main control board 7, and wherein, baroceptor is used for detecting the gas pressure in the gasbag 3, and gasbag 3 is located and holds a section of thick bamboo 2, holds a section of thick bamboo 2 and is made by soft material, and the barrel of holding a section of thick bamboo 2 is provided with the flexible pressure sensor (not shown in the figure) that is used for detecting finger force, and flexible pressure sensor and baroceptor all are connected with main control board 7 electricity.

The working principle of the child gripping force detector provided by the utility model is that a child puts the area of a finger to be detected corresponding to the flexible pressure sensor on the surface of the holding cylinder 2, then the child grips the holding cylinder 2, the air bag 3 in the holding cylinder 2 can be compressed and deformed due to the fact that the holding cylinder 2 is made of soft materials, the air pressure in the air bag 3 is increased, the flexible pressure sensor arranged in the cylinder body can be strained due to the deformation of the holding cylinder 2, the main control board 7 captures the change of the air pressure in the air bag 3 through the air pressure sensor, the whole gripping force value of the hand of the child is detected, and meanwhile, the main control board 7 detects the gripping force of a single finger of the child through the strain value of the flexible pressure sensor.

According to the working principle, the child grip strength detector provided by the utility model can be used for simultaneously detecting the whole grip strength of the hand of a child and the grip strength of a single finger, so that more comprehensive data can be provided for evaluating the rehabilitation effect and making a subsequent rehabilitation treatment plan. The child grip strength detector is suitable for pediatrics, families and individuals in hospitals, for example, is used for detecting the hand grip strength of children with hand injury symptoms, calibrating the hand strength grade of children, assisting doctors in judging the conditions, the rehabilitation state, the training effect and the like of patients, and performing the hand rehabilitation training of the children.

As shown in fig. 3 and 4, one end of the holding cylinder 2 is connected with the mounting frame 5, the mounting frame 5 is in a cup shape, the control unit 4 is mounted in the mounting frame, the control unit 4 comprises a main control board 7, a wireless transceiver module 8 and a battery 9, and the wireless transceiver module 8 and the battery 9 are both electrically connected with the main control board 7.

The length of the holding cylinder 2 is generally 10-15 cm, the outer diameter is generally 3-4 cm, and PU or silica gel can be selected as the material of the holding cylinder 2. The flexible pressure sensor is usually disposed on the inner surface of the holding tube 2, and in order to guide the child to place the finger on the corresponding region where the flexible pressure sensor is located, a pattern may be printed on the outer surface of the holding tube 2 to indicate that the child grasps the grasping region with the finger. In the present embodiment, as shown in fig. 1 and fig. 2, five finger accommodating grooves are formed on the outer surface of the grasping barrel 2, which correspond to four fingers and a thumb respectively in a fist state, so that the finger accommodating grooves can ensure that a child puts fingers at correct positions. It should be noted that, in the present embodiment, the plurality of flexible pressure sensors are distributed in five regions corresponding to four fingers and a thumb respectively in a fist state, but in other embodiments, the flexible pressure sensors may be selectively disposed in regions corresponding to some fingers, for example, the flexible pressure sensors are disposed only in regions corresponding to an index finger, which is not limited in the present invention.

In specific practical application, the main control board 7 may be provided with a self-checking module to realize power-on self-checking and reset self-checking functions, and may be further provided with an alarm to realize functions of alarming for abnormal air pressure, alarming for abnormal surface pressure, alarming for insufficient electric quantity, and the like.
