Parkinson disease (Parkinson ' s disease, PD) be a kind of nervous system degeneration disease that mainly occurs in disabling property above middle age.Static tremor is a kind of compound trembling, often be accompanied by alternative revolving before-motion of supination and flexion-extension, and can not occur with a kind of form merely, normally variable.Parkinson disease are early stage, and static tremor has undulatory property, alleviate when voluntary movement or disappearance temporarily, but occur again after the several seconds; Excited, anxiety or tremble when tired and increase the weight of, but when sleep or anesthesia, disappear.In addition, the Parkinsonian also show be slow in action, symptom such as festination.The amplitude of Parkinsonian's the behavior of trembling normally at random, frequency is fixed.The general Parkinsonian frequency of trembling mostly is 4-8Hz, and it is slow slightly generally to tremble than simple property, and amplitude is big slightly, and faster than the frequency of kinetic tremor, amplitude is smaller.Technology such as current domestic and international researcher utilizes electromyogram, electroencephalogram, the kinematic parameter that trembles are used for observing trembles and the equilibrated rhythm and pace of moving things of limbs and frequency, but normally the short time, the test mode of load is arranged.Because patient's nervous psychology, the characteristics such as fluctuation of trembling in early days, check result is prone to than large deviation, makes objective assessment patient's the behavior of trembling comprehensively of this class technology.Therefore at present, only observe the situation of trembling to the behavior of trembling is general during domestic and international department of neurology is clinical by the doctor, and the reason of its generation of subjective judgment and degree, do not set up objective quantitative recording means at the parkinsonian tremor behavior, can't provide quantitative infallible data for clinical diagnosis and treatment; And there is not a kind of sophisticated detection by quantitative device to be used for the tremble clinography of behavior of Parkinsonian yet.
This utility model has proposed a kind of parkinsonian tremor behavior continuous and quantitative recording equipment based on the three dimension acceleration sensor technology at Parkinsonian's tremble behavioral characteristic and the deficiencies in the prior art.
Summary of the invention
This utility model technical issues that need to address provide a kind of quantitative recording equipment of the behavior of can the continuous detecting Parkinsonian trembling, and realize that Parkinsonian's underload, long-term, quantitatively trembling of continuing detect and record.
The technical scheme that this utility model solves the problems of the technologies described above is: design a kind of Parkinsonian based on three dimension acceleration sensor technology behavior continuous and quantitative recording equipment that trembles.This recording equipment adopts three dimension acceleration sensor to detect the acceleration of Parkinsonian's limb tremor behavior, adopt the acceleration signal that trembles of Flash memorizer continuous record collection, simultaneously device can by serial communication or USB interface be connected to computer tremble signal download, analyze and processing.The described recording equipment of this utility model by the three-dimensional acceleration sensing module 1., filter amplification circuit 2., the Single-chip Controlling processor 3., memorizer 4., the usb communication circuit 5. and power supply 6. constitute.The three-dimensional acceleration sensing module is gathered the acceleration signal of Parkinsonian's limb tremor behavior, the input of filter amplification circuit connects the outfan of acceleration sensing module, receive acceleration signal, other noise signals of filtering, and be sent to Chip Microcomputer A/D interface input by outfan after amplifying, A/D modular converter in the single-chip microcomputer carries out A/D conversion to acceleration signal, and it is sampled and handles the back and send into by output port and carry out recording storage in the memorizer.
Kinesiology characteristics according to the behavior of Parkinsonian's limb tremor, this utility model adopts the three-dimensional acceleration sensing module to detect the three-dimensional acceleration signal that patient's limb tremor is produced, by Single-chip Controlling A/D conversion acceleration signal is sampled then, and carry out the pretreatment of signal, deposit the acceleration signal that trembles after handling in memorizer, realize continuous and quantitative record the behavior of patient's limb tremor.When the acceleration of behavior that the patient is trembled quantitatively writes down, can also the data of above-mentioned quantitative record be sent into computer by the usb communication circuit, record data are carried out analyzing and processing and download, for Parkinsonian clinical examination provides the objective quantitative behavior kinesiology data of trembling.
Because the undulatory property of parkinsonian tremor behavior, the patient who causes for fear of the testing process of trembling is nervous and tired, recording equipment described in the utility model adopts microminiaturized Wearable design, device can be designed to outward appearances such as Wristwatch-type, wrister type, make sufferer still normally take action and live when continuous and quantitative trembles behavior record carrying out.
The beneficial effects of the utility model at the randomness and the passivity of parkinsonian tremor behavior, provide objectively quantitatively recording equipment, for clinical diagnosis and treatment provide quantitative infallible data; And this recording equipment has, and compact conformation, volume are little, the advantage of underload, can realize that Parkinsonian's underload, long-term, quantitatively trembling of continuing detect and record.
