Description

Portable body equilibrium function tester

One, technical field:

This utility model relates to a kind of Medical Instruments, especially is applicable to the portable body equilibrium function measuring instrument that human body stance, sitting balance function quantitative are measured.

Two, background technology:

The measurement of body balance particularly relates to the aspects such as personnel's screening of clinical diagnosis, clinical rehabilitation, geriatrics, sports medical science and special trade of nerve injury aspect to some disease significant.Studies show that keeping of total balance of the body is a comprehensive neuromuscular process, body balance is subjected to tripartite face such as vision, somesthetic sensibility and vestibular sensations system and rings.At present, the measurement of body balance is mainly contained static method and dynamic method, dynamic method generally is to adopt observation method or scaling method to measure tested daily habituation action and it is analyzed, though have ease for operation, its precision is subjected to very big restriction; Static rule is that utilization monitoring human center of gravity is rocked the purpose that reaches the measurement body balance, because it has higher letter, validity, thereby this method is greatly promoted in clinical and experimentation.Up to now, the gauge of releasing at this method whether move according to the platform bottom and can be divided into static and dynamic two classes substantially again: static measurement can use calculated with mathematical model go out the centre-of gravity shift situation according to the stressed situation of change of mechanics sensor bottom the measuring table, can remove sense of vision factor influence, but owing to can not get rid of the interference to vestibular sensations of the proprioceptive information introduced by sole portion; Kinetic measurement can make it to get rid of the influence of somesthetic sensibility to vestibular sensations by the computer controlled measurement platform motion, can carry out independent measurement to three factors that influence equilibrium function, but the price height of this instrument and equipment has limited its scope of application.There is Crinis Carbonisatus to understand utilization billiard table elimination somesthetic sensibility recently, reach the balancing a survey instrument of measuring body balance by measuring people's body Pour angle, because the unstability of this instrument, cause tested injuring unexpectedly easily, this instrument can not be got rid of the influence of somesthetic sensibility fully because the range of movement of billiard table is limited simultaneously.

Three, utility model content:

The purpose of this utility model provides a kind of portable body equilibrium function tester that utilizes light-electricity and image processing techniques to measure human body stance, sitting balance function.

Concrete scheme of the present utility model is: a kind of portable body equilibrium function tester, comprise CCD photographic head, USB line, computer, sighting target, printer and total balance of the body analysis software, and it is characterized in that: the head sighting target is fixed on tested head central authorities; Be suspended on directly over the head sighting target and height can link to each other with computer by the USB line by freely regulated CCD photographic head, the computer installation total balance of the body analysis software of assembling printer.

Described installation total balance of the body analysis software on computers comprises image acquisition, image recognition, date processing, data print module and data base's five parts.

This programme is: can regard this principle of rigid body as according to human body, the sighting target and the gravity center of human body that are fixed on head central authorities will move in the same way, therefore can be used as the index point that total balance of the body is measured, and can use the ergonomics principle to be converted to the gravity center of human body.Image through CCD photographic head input computer only forms the sighting target luminous point through Flame Image Process, the gravity center of human body moves and also just is converted into the some motion of sighting target luminous point on two dimensional surface, by this movement locus on two dimensional surface being carried out just energy quantitative measurement body balance of software analysis, at last with data input database or printing reports.

Adopt the beneficial effect of such scheme to be: owing to this tester can freely be dismantled each several part, and the each several part volume is little, and light weight is easy to carry; Adopt electro-optical technique and image processing techniques quantitative measurement body balance, can measure respectively three factors that influence body balance effectively; The body balance measuring software system friendly interface of this instrument is measured quick, easy to operate; Cost is low, is of value to this instrument applying in each field.
