Problems solved by technology

[0005] The existing finger pulse transducer has a simple structure and is not beautiful. It lacks a structure for fixing to the experimental platform, lacks a structure for properly supporting the hand, and has poor comfort. Involuntary movements of the human body may occur during the detection process "Pseudo-neural fatigue" and other disturbances, resulting in inaccurate measurement results

Embodiment 1

[0035] A finger force sensor, including a bracket 1, a sphere 2 and an adjustment device 3. The two ends of the bracket 1 are connecting parts 4, and the middle part is a receiving part 5, wherein the connecting part 4 is used to connect with the experimental platform, and the receiving part 5 is an arch Shaped gantry structure, used to accommodate the sphere 2 and the subject's hand; the adjustment device 3 includes a guide post 6, a guide sleeve 8 and a locking piece 7, wherein the guide post 6 passes through the receiving part 5 and is connected directly above the sphere 2, A guide sleeve 8 is provided on the outside of the guide column 6, and the guide column 6 can rotate and slide in the guide sleeve 8; as a preferred method, the guide sleeve 8 includes a sleeve body 11 and a claw 12, wherein the sleeve body 11 is sleeved on the Outside the guide column 6, the sleeve body 11 and the receiving part 5 are detachably fixedly connected by means of bolts, buckles, etc., and the...

Embodiment 2

[0042] A muscle response monitoring system, including the finger force sensor in embodiment 1, a stimulator for electrically stimulating the forearm nerve, a collector for data collection and a user terminal for receiving data, the finger force sensor The tension and pressure sensor 20 is connected in communication with the collector, and the collector is respectively connected in communication with the stimulator and the user terminal, wherein the model of the collector is BL-420N, and the user terminal can be a computer.

[0043] Specifically, the subject puts the finger to be tested lightly on the button 9 of the sphere 2 as in the method of Example 1, and the other fingers and palms naturally hold the sphere 2, and the stimulator is bound to the wrist along the long axis of the arm. And ensure that the two stimulating electrodes are completely attached to the skin. Since the finger force sensor provided by the present invention is used with the palm of the subject facing up...

Abstract

The invention discloses a finger force sensor and a muscle response monitoring system containing the sensor, and relates to the field of human muscle reaction experiments. The finger force sensor includes a support, a sphere and an adjustment device; the support adopts an arched gantry structure, the two ends are connection parts, the middle part is an accommodating part, the connection parts areused for being connected with an experimental platform, and the accommodating part is used for accommodating the sphere and a hand of a subject; the sphere is provided with a button, and the button isprovided with a pull-press sensor for receiving finger response; and the adjustment device is used not only to drive the sphere to lift and rotate, but also to fix the position of the sphere. The finger force sensor provided by the invention can provide a better support for the hand of the subject, prevent the interference of ''pseudo-nerve fatigue'' caused by involuntary movement of a human bodyin the detection process, improve the accuracy of the measurement results, and has better comfort level of use.

Description

technical field [0001] The invention relates to the field of human muscle response experiments, in particular to a finger force sensor and a muscle response monitoring system including the sensor. Background technique [0002] Skeletal muscle fibers are controlled by motor nerve fibers. After the nerve fibers are stimulated, the excitation of the nerve fibers is transmitted to the corresponding muscle fibers in the form of action potentials, and the muscle fibers are caused to contract or relax through excitation-contraction coupling. The excitation of nerve fibers is manifested in the bioelectricity on the cell membrane—the generation and conduction of action potentials. Subsequently, muscle cells contract, which is reflected in changes in tension and length. The mechanisms and forms of expression of the two are different. [0003] By electrically stimulating the forearm nerve and observing the muscle's response to the change in the stimulation intensity, we can understand ...
