Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with specific embodiments.

[0011] refer to Figure 1 to Figure 3 , the invention provides a hand-held nerve function evaluation instrument. Including host 1, sleeve 2 (sleeve 2 with Velcro 3), hard template ( figure 2 shown). Host 1 contains LCD screen, accelerometer, gyroscope and processing circuit; cuff 1 fixes host 1 to the far end of the arm; there is a helical thread on the hard template. With the arm hanging, the patient touches the hard template with one finger, and rotates once from inside to outside along the track; then rotates once from outside to inside. The trajectory of the arm movement is calculated by the accelerometer and gyroscope, and the power spectrum analysis is performed on the trajectory of the arm movement by the data processing circuit, and the degree of tremor is reported through the LCD screen; thus the degree of tremor is judged. It can judge the tremor in two mai...

Abstract

The invention discloses a handheld neurologic function evaluation device. The device comprises a host, a sleeve and a hard template, wherein the host comprises a liquid crystal screen, an accelerometer, a gyroscope and a data processing circuit; the host is fixedly bound on the far end of an arm by virtue of the sleeve; the hard template is provided with a spiral line. When the device is used, the hard template is put on a table flatwise, and arms of a patient are suspended; a single finger of the patient touches the hard template and rotates once from the inside to the outside along a track, and then rotates once from the outside to the inside; the track of arm movement is obtained by calculation of the accelerometer and the gyroscope; and the data processing circuit performs power spectrum analysis to the track of arm movement, and sends out a report of the degree of tremor through the liquid crystal screen, so that the degree of tremor is judged. The handheld neurologic function evaluation device can be used as a portable noninvasive digital instrument for evaluating movement function abnormality (such as Parkinson's disease and the like) and is convenient to use, operate and carry.

Description

technical field [0001] The invention relates to a hand-held nerve function evaluation instrument, which belongs to the technical field of medical devices. Background technique [0002] Parkinson's disease (PD) is clinically characterized by slowness of movement, resting tremor, rigidity, and postural reflexes. The Unified Parkinson's Disease Rating Scale (UPDRS) is a widely accepted subjective evaluation method for the severity of Parkinson's disease in clinical practice. In order to overcome the shortcomings of strong subjectivity, the usual practice is to digitally collect the patient's arm movement signals and input them into the computer for programming and processing. The process is more complicated and not easy to carry. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hand-held nerve function evaluation instrument for the deficiencies in the prior art, and the technical scheme is as follows: [0004] H...
