Description
The present invention relates to a kind of instrument of Measurement and analysis gravity center of human body's stability, particularly adopt the stand instrument of attitude center of gravity swinging track of microcomputer Measurement and analysis human body.
The present invention is with reference to Japan
The G4301S type stasiofax that ィ マ Co., Ltd. produces.This instrument is made up of measuring table and main frame two parts, its technical scheme is by stand measuring table and body weight, center of gravity swinging distance (total length of center of gravity swing), center of gravity hunting range (area) are carried out measurements and calculations by analogue computer of three human bodies that load sensor supported, drive the XY monitor and draw center of gravity swing state figure, and convert digital signal to and show in real time.But the shown above-mentioned three kinds of numerals of this instrument will be leaned on manual record, and the function that does not write down automatically, preserves and repeat to export is not set up health record management system yet.This instrument adopts analog circuit and XY monitor, and measured upper frequency is partly filtered, and frequency resolution is lower, and particularly the analogue technique scheme can not be carried out the spectrum analysis of center of gravity swing state.Secondly load sensor is had only hand reset, need often to adjust gravity center of human body's zero-bit.
Task of the present invention is in the instrument of measuring gravity center of human body's swing state, improve frequency resolution, carry out spectrum analysis, draw amplitude-frequency characteristic and phase-frequency characteristic figure, can write down automatically, preserve, retrieve, revise also and can repeat output information and drawing, and then set up health record management system, load sensor is added the automatic zero set function.
The invention is characterized in that what be connected with preamplifier is an A/D changer, and being connected to computer as computer interface, computer also is furnished with floppy disk and hard disk drive keyboard, display, printer and drawing apparatus are formed computer measurement and analytical system.And be the exploitation under Chinese and English operating system is supported of the supporting dedicated computer software of this hardware system.This cover special-purpose software comprises: 1. signals collecting and control
2. date processing and storage
3. dynamic spectrum analysis
4. platform adjustment and verification
5. medical record analysis
6. medical record retrieval and modification
7. medical record is printed
8. amplitude-frequency characteristic and phase-frequency characteristic are drawn
9. the center of gravity swing state is drawn
This modular organization programming has not only increased the reliability and the transparency of software, and is convenient to revise and expand.
The present invention has realized following function under the cooperation of above-mentioned hardware and software:
Whole operation use of the present invention is to carry out catechetical human computer conversation on indicator screen, and shows various states and result of calculation.Can import, show, Chinese and English prints.Therefore can measure by specification step of having set and time, and can carry out the medical record analysis.If exceed the scope of set standard in using, computer can be protected and screen prompt automatically.
Signals collecting and control software (1):
At first whether check measurement platform sensor zero point was in normal range, reported to the police during the overshoot scope, and indicated and should adjust measuring table, returned the main menu state then.If system is normal zero point, then preserve the state at zero point, so that realize the automatic zero set function, receive subsequently from the information of the measured's of keyboard input medical record number, name, age, sex, occupation, first visit or further consultation, and generate the initial value of sequence number automatically as medical record management.When measuring, at first calculate body weight.Then both feet, left and right stand on one leg and the open and close eye is combined under six kinds of metering systems these information of preservation, and obtain the center of gravity swing information with certain sampling time.Because gravity center of human body's hunting frequency is generally at 0.2-0.3Hz, highest frequency is 2-3Hz.As long as selecting cut-off frequency is 15Hz, sampling time interval is not more than 32 milliseconds, when hits was chosen to be at 512, its frequency resolution can reach 0.06Hz, and is therefore meticulous and true than the figure of drawing on the XY monitor at the center of gravity swing state figure that marks with digital quantity on the drawing apparatus.
Date processing and storage software (2) mainly are that the data under six kinds of metering systems in the software (1) are calculated so that obtain coordinate figure and calculate the length and the hunting range of center of gravity swinging track, send on the floppy disc in the lump together with the initial value of human body weight and medical record management and preserve.Center of gravity swing state software for drawing (9) can be drawn its figure on drawing apparatus, dynamic spectrum analysis software (3) is the coordinate values that is drawn according to software (2), calculate the value of amplitude-frequency characteristic and phase-frequency characteristic with sad analytical method in the quick richness, amplitude-frequency characteristic and phase-frequency characteristic software for drawing (8) can be drawn its figure on drawing apparatus.
The relevant medical record data of medical record retrieval and the in store artificial input of modification software (6) and the data of being calculated can be retrieved by name, medical record number, sequence number, the data of artificial input can be revised, error correction is arranged, and the data of calculating are inaccurate to be revised, and the function that shows and print is arranged.Medical record analysis software (5) is preserved the initial value of medical record management, can import the graphic feature of center of gravity swing state.Can import doctor's first visit impression and first visit suggestion.Can import the situation of making a definite diagnosis of medical outcome.Type, left right model, multicenter type before and after in software, the shape facility of center of gravity swing state figure being decided to be approximately, ask heart type, diffuse type, fan type, bias type and other eight kinds of shape facilities, made things convenient for the feature analysis of doctor disease.The zeroing of load sensor is that the error measure calibration of measuring table is used by platform adjustment and verification software (4).Measure the zero point to three pick offs of platform before its another function is to use in advance, and its error surpass to adjust in limited time, display then transfers the digital quantity of out-of-limit its each pick off of demonstration to, so that selectively carry out hand reset, mixes up the back and recovers normal condition automatically.
The present invention help department of neurology, clinical Medicine and Surgery, department of eye,, early diagnosis such as gynecological, kinesiology, anti-motion medicine, occupation disease.
It is example that the present invention only lifts three kinds of diseases for state of an illness diagnosis effect:
Cervical vertigo is the umbrella shape feature in the center of gravity swing state figure biped cube formula of closing one's eyes, and the spectral characteristic midband is widened, and frequency obviously increases.
Neurologic vertigo or drug intoxication patient, center of gravity swinging track length is significantly increased, and the amplitude-frequency characteristic intermediate frequency spectrum is distributed in the whole frequency domain.
Vascular vertigo person's center of gravity swinging track figure forms the feature of oblique line shape.
