Description

Measurer of cervix-trunk flexibility

This utility model is a kind of measurement human body neck-trunk pliability measuring instrument.

The method of measuring is at present: adopt the method for " the prostrate back of the body is stretched " to measure the total length of the method amount of being experimenter's neck and trunk in the U.S..Be the experimenter prostrate both hands place lower back on pad, lift trunk on as far as possible, then with flexometer amount experimenter's nose and ground level, deducting nose with trunk and the high length overall of neck is the measurement achievement to the difference of ground level, difference is more little, achievement is good more.

The major defect of this method is: 1. degree of raising is influenced by muscle of back strength size on the trunk, and degree of raising is low on the people of muscle strength difference, and difference is big, but his pliability (degree varies that is spine bends backward is fixed poor) is poor.The pliability that therefore can not correctly reflect spinal column; 2. because trunk ratio difference, institute subtracts difference and proportional error also can occur, and identical if any the recurvate degree of two people, people's trunk is high 50 centimetres, on 40 centimetres of degree of raising, 10 centimetres of differences, another person's trunk is high 40 centimetres, on 32 centimetres of degree of raising, 8 centimetres of differences, on them degree of raising be similarly trunk high 4/5, but the short people of trunk obtained estimating preferably, and therefore measurement error has taken place; If 3. to trained player and acrobat, then the method more can not be used, because the spinal column dorsiflex is when surpassing 90 °, then difference can strengthen on the contrary.Pliability that for this reason can not the correct response spinal column.

This utility model replaces original measuring method with neck-trunk pliability measuring instrument exactly, reaches science, accuracy, the reliability of measurement.

This utility model is finished with following most preferred embodiment.

Fig. 1,2 is measuring instrument (abbreviation) axonometric drawing.

Partly form by three with reference to Fig. 1,2 measuring instruments: the handrail column that height-adjustable measurement chair and measurement chair are connected; Half garden angel measuring instrument of adjustable-height and longitudinal separation constitutes.

Height-adjustable measurement chair is by seat 5, seat axle 8, and support 9 constitutes, be welded with backing plate 18 in the side of seat board 5, side lever 13 is welded on the backing plate 18 by side lever cover 16, and column cover 4 is welded in seat board 5 belows by seat board 5, and seat board 5 can move up and down and rotate by seat axle 8.

With measuring handrail column that chair is connected is by vertical rod 1, sliding sleeve 2, bar 3, column cover 4 constitutes, and bar 3 is welded on the sliding sleeve 2, and vertical rod 1 can be overlapped in 4 at column and be moved up and down, use the jackscrew fixed position then, sliding sleeve 2 can move up and down in vertical rod 1, uses the jackscrew fixed position then.Be vertical rod 1, bar 3 all can be according to its height of altitude mixture control of human body.

Half garden angel measuring instrument of adjustable-height and longitudinal separation is by rotating shaft 7, driving lever 6, bull stick 21, rotating shaft cover 20, jackscrew 19, pointer 12, inclinometer 14 bars 15 that crouch, and the bar axle 17 that crouches, side lever cover 16, side lever 13, motion bar 10, stick 11 constitutes.Its rotating shaft cover 20 is welded on the bar 15 that crouches, and the bar 15 that crouches is welded on the side lever cover 16, and stick 11 is welded in the rotating shaft 7, driving lever 6, and bull stick 21, pointer 12, inclinometer 14 links with rotating shaft 7.Such structure can realize regulating the requirement of height and longitudinal separation.

As regulate height: motion bar 10 can move up and down at stick 11, rotating shaft 7 bars 15 for sleeping in, and side lever cover 16 can move up and down along side lever 13, and jackscrew is fixed its position then.

Regulate longitudinal separation: rotating shaft 7 can be overlapped 20 move left and right by rotating shaft, uses jackscrew 19 with its fixed-site then, and rotating shaft 7 can also overlap 20 by rotating shaft, and the bar 15 that crouches moves forward and backward along the bar axle 7 that crouches, and fixes its position with the jackscrew among the figure then.Rotating shaft 7 itself also is subjected to the effect of stick 11 to drive driving lever 6, bull stick 21, and pointer 12 rotates." half garden inclinometer just can be realized the adjusting of top to bottom, left and right, front and rear distance, reaches the accuracy of measurement like this.

During measurement, the experimenter is in the face of vertical rod 1, hand steered bar 3, be seated on the seat 5 of measuring chair, regulate the height of vertical rod 1, make nose be close to vertical rod 1, the tester is at this moment with the 3rd part: half garden angel measuring instrument of adjustable-height and longitudinal separation is transferred to concordant with experimenter's umbilicus height, make stick 11, motion bar 10 is close to the spinal column of human body, and be higher than the back side of head, and put the side of half garden angel measuring instrument at human body, make pointer 12 be positioned at zero-bit on the inclinometer 14, with belt column is overlapped 4 then, with people's buttocks position tighten, the experimenter does the backward wing of coming out boldly at this moment as far as possible, and the back side of head portion of head promotes motion bar 10 → stick 11 → driving lever 6 → bull stick 21 → rotating shaft 7 → pointer 12 and is synchronized with the movement, make pointer 12 turn over certain angle by 0 °, demonstrate measurement result on inclinometer 14, angle is big more, and achievement is good more.

Measuring instrument disclosed in the utility model and former method compare: the people gets seat during owing to measurement, backbone is in the dissection neutral position, when coming out boldly layback, centre of body weight is offset backward, trunk weight is owing to centrifugal force is backward lower, then power and the come out boldly backward wing of trunk weight under backward is consistent, can get rid of owing to muscular strength is weak affects the factor that action is finished, and its pliability is measured in the backward motion that makes backbone do amplitude peak, and the prostrate back of the body of former method is stretched, human body is in the prone position, lift trunk and do the back of the body and stretch action, must overcome the earth's core to the gravitation of trunk, because gravity relation, lift the size of the full backrest muscular strength of trunk amount and come execution, strength is big, and raising height is just high, otherwise just low, backbone can not be done the rear very back of the body of amplitude peak and stretch action, thereby pliability that can not the correct response backbone.

This measuring instrument manufactures conveniently, and is cheap, can make of waste material, and it is applied to the measurement of human body pliability quality, and the sportsman selects, convalescent home, and urgent disorder in orthopaedics hospitals etc. check the recovery extent of function of joint, are a kind of novel survey tools.
