Description

Technical Field

[0001] The present invention relates to the technical field of data acquisition, and in particular to a grip strength data acquisition method and system. Background Art

[0002] A handgrip dynamometer measures the force applied during gripping. Traditional handgrip dynamometers are calibrated and estimated by the manufacturer, and the grip force is expressed based on the deformation of a spring or tension spring, making it imprecise. Existing electronic handgrip dynamometers use sensors to measure grip force parameters, supplemented by a grip travel adjustment mechanism. These sensors can measure a wide range of grip force data and provide feedback to the user through digital displays. Electronic handgrip dynamometers are also widely used in rehabilitation training and other fields. For example, various vital signs of postoperative patients are measured to assess their recovery, and grip strength is a key piece of data.

[0003] However, current electronic handgrip dynamometer products are mostly for personal exercise purposes and lack relevant data statistics functions. When relevant institutions collect data and assess the status of a large number of patients, they can only perform handgrip strength tests and data registration on each patient one by one, and then manually enter the data into the analysis equipment. This process is time-consuming and labor-intensive, heavily dependent on manual labor, and errors are prone to occur during data registration. Summary of the Invention

The terms "including" and "having," as well as any variations thereof, in the embodiments of the present invention, are intended to cover non-exclusive inclusions.

[0049] Example 1

[0050] See also Figure 1 ,like Figure 1 As shown, a grip strength data collection method disclosed in an embodiment of the present invention includes the following steps:

[0051] 101. Decompose to trigger the collection state.

[0052] In this embodiment, the handgrip dynamometer is used in the form of a pair. When the two are stored, they are adsorbed and attached face to face under the action of the positioning magnet, and after being disassembled and separated, the collection state is triggered.

[0053] As an optional implementation, receiving a collection instruction and detecting whether the contact is disconnected;

[0054] If the contact is detected to be disconnected, the acquisition state is triggered.

[0055] Specifically, several contacts are set on the surface of the hand dynamometer, so that when the two are adsorbed and attached face to face, the contacts of the two touch each other and become conductive. Therefore, by detecting whether the contacts of the two are disconnected, it can be determined that the two hand dynamometers are disassembled and separated. At this time, the hand dynamometer powers on automatically, enters the collection state, and waits for the grip strength data to be measured.

[0056] 102. Based on the acquisition sequence, measure the grip strength data of the current user.

[0057] In this embodiment, after being disassembled and separated, the hand dynamometers independently enter a collection state, waiting for the user to grasp and apply force.

[0058] As an optional implementation, collecting cache grasp data;

[0059] Check whether the cached data is greater than the screening threshold;

[0060] If the initial grasping data in the cache is greater than the screening threshold, the grasping data in the cache is stored as the grasping force data.

[0061] Specifically, the user's grip strength measurement is not completed instantly, and usually lasts for several seconds. The grip strength value during the gripping process fluctuates greatly and does not change linearly. Usually, the maximum grip force exerted by the user is selected as the grip strength data for the current grip strength measurement.

[0062] Therefore, a screening threshold is set here. Only cached grip data that is greater than the screening threshold will be considered valid data to avoid external forces generated by actions such as handing, picking up, and bumping being mistakenly recorded as grip strength data.

[0063] As another optional implementation, monitoring is performed to determine whether cached grip data greater than the grip force data is collected;

[0064] If so, the cached grip data that is greater than the grip strength data is used to update the grip strength data.

[0065] It is understandable that different users have different force characteristics, and the curve characteristics of the grip strength data vary greatly. Here, the maximum grip strength applied by the user is used as the grip strength data for the current grip strength measurement. During the current cached grip process, whenever cached grip data that exceeds the current grip strength data appears, the current grip strength data will be updated to ensure that the maximum grip strength applied by the user is collected.

[0066] As another optional implementation, a clear instruction is received to clear the currently stored grip strength data.

[0067] Specifically, assuming that a severe external force such as a bump or fall occurs during the use of the hand dynamometer, or the user using the hand dynamometer is not the same as the user indicated by the collection sequence, then it is obvious that the grip strength measurement needs to be repeated. At this time, a clear command is input to the hand dynamometer to re-collect the grip strength data.

[0068] Here, the clearing instruction can be input in various ways. For example, it can be set that when the hand dynamometer is gripped continuously for more than ten seconds, it is regarded as a clearing instruction being input to the hand dynamometer.

[0069] Therefore, the handgrip dynamometer can accurately and efficiently collect grip strength data of users in the collection sequence in sequence.

[0070] 103. Docking to trigger the transmission state.

[0071] In this embodiment, when both handgrip dynamometers record grip strength data and the two handgrip dynamometers are reattached and adsorbed after being disassembled and separated, they enter the transmission state and the collected grip strength data is automatically uploaded.

[0072] As an optional implementation, detecting whether the contact is conductive;

[0073] If the contact is found to be conductive, it is then checked whether the two grip force data are collected;

[0074] If two grip strength data are measured, the transmission state is triggered and communication is connected to the upper device.

[0075] Specifically, after the grip strength data is collected and the two dynamometers are attached and adsorbed, they will establish a communication connection with the upper-level device.

[0076] Here, the upper-level device may be a cloud server or a portable smart terminal device, which is used to collect the grip strength data collected by the hand dynamometer or to perform wireless control on the hand dynamometer.

[0077] 104. Upload the current user's grip strength data.

[0078] In this embodiment, for the hand grip dynamometer that has established a communication connection with the upper level device, the hand grip data is uploaded.

[0079] As an optional embodiment, the database of the superior device stores the acquisition sequence, and the data items of the acquisition sequence include at least sequentially encoded user IDs and measurement data corresponding to each user ID;

[0080] In the database of the upper-level device, the two grip strength data are used to update the measurement data of the two user IDs corresponding to the current collection node.

[0081] Here, a database is provided on the upper-level device side to record and update the grip strength data of each user.

[0082] As an optional implementation, based on the sequential coding of the acquisition sequence, two user IDs corresponding to the next acquisition node are read and output.

[0083] Specifically, after the grip strength data is updated to the corresponding user ID entries in the database in sequence, the superior device reads the two user IDs for which grip strength data should be collected according to the collection sequence and outputs them to inform the outside world which two users need to collect grip strength data next.

[0084] Taking a hospital ward as an example, assume that all patients on this floor are undergoing rehabilitation assessments. The user IDs of each patient are sorted in ascending order based on the ward number and bed number. Medical staff can then select two patients at a time in the order of ward number and bed number, disassemble the handgrip dynamometer, and measure the handgrip strength data.

[0085] For example, assuming that the two handgrip dynamometers are handgrip dynamometer No. 1 and handgrip dynamometer No. 2, handgrip dynamometer No. 1 is provided to patient No. 1 for handgrip strength measurement, and handgrip dynamometer No. 2 is provided to patient No. 2 for handgrip strength measurement. After both patient No. 1 and patient No. 2 complete the handgrip strength measurement, the medical staff adsorbs and fits handgrip dynamometer No. 1 and handgrip dynamometer No. 2, triggering the upload of handgrip strength data. The handgrip strength data of patient No. 1 is uploaded and updated to the measurement data corresponding to its user ID in the database, and the handgrip strength data of patient No. 2 is uploaded and updated to the measurement data corresponding to its user ID in the database. At this point, the handgrip strength data of patient No. 1 and patient No. 2 are collected.

[0086] Then, the medical staff provides handgrip dynamometer No. 1 to patient No. 3 for grip strength measurement, and provides handgrip dynamometer No. 2 to patient No. 4 for grip strength measurement, and so on. Without the need for manual recording and manual entry, the grip strength data upload process can be completed efficiently by performing the adsorption and bonding action on the two handgrips, and there will be no data registration errors.

[0087] In summary, after the two handgrip dynamometers are separated, they can detect and record the grip strength data separately. After recording the grip strength data and adhering to it, the grip strength data can be uploaded. There is no need for manual data recording during the process, which greatly improves the efficiency of the collection work and does not cause data errors due to manual operations.
