Description

A kind of joint angles measuring device

Technical field

This utility model relates to medical measuring device, is specifically related to a kind of have voice unit output, the joint angles measuring device of angle that the joint exists under physiology or pathological state and range of activity.

Background technology

Clinical medical development requires increasingly highly to the data order of accuarcy, and check result directly influences clinical diagnosis and anaphase, so each item check result in clinical treatment and the rehabilitation should try one's best precision, standardization, digitized.

Existing joint angles measuring method mainly is that range estimation and angle block gauge are measured.Wherein, the error of ocular estimate is bigger, generally only is used for rough qualitative examination but not concrete clinical treatment and rehabilitation; The angle block gauge metering system is fixed, and can not satisfy the measurement demand of user individual, and the accuracy of reading is difficult to control; Existing electronics angle measurement unit is relatively heavier usually, is not suitable for the angular surveying in joint.

But in concrete medical practice process; The measurement inspection in various joints is indispensable; And the error that is wherein produced by artificial reading also is difficult to avoid, and therefore vast medical worker is devoted to study always and can personal error be reduced to minimum joint angles survey tool.

Summary of the invention

The subject matter that this utility model solved is; Overcome the defective that existing measuring device exists; And a kind of joint angles measuring device with voice unit output is provided; It can accurately be measured, so that reflect range of activity, physiology or the pathological state in various joints truly according to active characteristics of human synovial and clinical medical measuring principle to various joints.

For achieving the above object, the technical scheme of this utility model is:

A kind of joint angles measuring device; Comprise fixation measuring arm, movable gage beam, central shaft, angel measuring instrument and voice unit; Said angel measuring instrument is arranged at said central shaft; One end of said movable gage beam is provided with said voice unit, and the said movable gage beam other end is connected through said central shaft with an end of said fixation measuring arm.

Said movable gage beam and said fixation measuring arm adopt transparent material.

Said voice unit is connected said data wire and said movable gage beam keeping parallelism, the graticule of angle when being used to measure through data wire with said angel measuring instrument.

Said movable gage beam can be made 360 degree around said central shaft and measure rotation.

Said angel measuring instrument comprises angular transducer, analog-digital converter, data processor and coffret.

Said data processor comprises flash chip, can write down many group measurement data.

Said coffret adopts USB interface, Mini-USB interface, blue tooth interface or wireless lan interfaces.

Said coffret is arranged at the opposite side of said fixation measuring arm, and said coffret is connected said data wire and said fixation measuring arm keeping parallelism, the graticule of angle when being used to measure through data wire with said angel measuring instrument.

This utility model is simple in structure, easy to operate, not only can reflect measured's physiology or pathological state intuitively, has also avoided the artificial error that reads, has made measurement result more accurate.

This utility model comprisesfixation measuring arm 101, movable gage beam 102, central shaft 103, angelmeasuring instrument 104 and voice unit; Angel measuringinstrument 104 is arranged at central shaft 103; One end of movable gage beam 102 is provided withvoice unit 105, and movable gage beam 102 other ends are connected through central shaft 103 withfixation measuring arm 101 1 ends.The background of movable gage beam 102,fixation measuring arm 101 andvoice unit 105 adopts transparentmaterial.Voice unit 105 is connected withangel measuring instrument 104 throughdata wire 106,data wire 106 and movable gage beam 102 keeping parallelisms, the graticule of angle when being used to measure.Movable gage beam 102 can be made 360 degree around said central shaft 103 and measure rotation.

See also Fig. 2:

Angel measuringinstrument 104 comprises angular transducer, analog-digital converter, data processor and coffret 107.Data processor comprises flash chip, can write down many group measurement data.Coffret 107 adopts USB interface, Mini-USB interface, blue tooth interface or wireless lan interfaces.Coffret 107 is arranged at the opposite side offixation measuring arm 101, andcoffret 107 is connected withangel measuring instrument 104 throughdata wire 106,data wire 106 andfixation measuring arm 101 keeping parallelisms, the graticule of angle when being used to measure.

In the detailed process that joint angles is measured, the job step of this utility model is following:

At first, a fixed end is convenient in the joint,, is placedfixation measuring arm 101 1 sides like upper arm of kneed thigh, elbow joint etc.;

Then, rotary moveable gage beam 102 to be agreeing with an end of joint motion, like the underarm of kneed shank, elbow joint etc., forms the angle in joint;

At last, listen to the joint reading thatvoice unit 105 is quoted, the angle that utilizes thedata wire 106 of two gage beams to form is again simply estimated verifying this angle, and carries out record according to actual needs.
