Description
Technical field
The utility model is related to medical measuring apparatus technical field, particularly relates to a kind of forearm rotation angle measurement
Device.
Background technology
Performance of the forearm anglec of rotation to hand function has important effect.Before forearm rotation during obstacle, though can be with shoulder joint
The abduction of section does the compensatory of part, but it is write, and detains button, and twisting a towel, it is influenced to different extents to wait action；Forearm revolves
Afterwards during obstacle, shoulder joint can not be compensatory, and the action that food is sent into the medium forearm supinated of mouth will be affected.How accurately to survey
Amount forearm spinfunction is particularly important.In clinical at present, the method for forearm wheel measuring is more, but the subjectivity of doctor
Stronger, different doctors often have differences to the result that same patient measures.Research and development one kind is simple in construction, can directly read
The measuring appliance of patient forearm's anglec of rotation is the task that the art needs to complete.
The content of the invention
The purpose of this utility model is to provide a kind of simple in construction, easy to use, can directly read patient forearm's rotation
The measuring appliance of angle.
In order to achieve the above object, this practicality is new uses following structural principle：A kind of forearm rotation angle measurement device,
By bottom plate, restraint strap, handle, locating piece, L-shaped axle, bearing block, swing rod, riser, rivet, sliding block pointer, spiral shell mesh, screw, nylon
Hasp and pressing plate composition, its feature are：Rectangular base plate plane longitudinal direction one end passes through pressing plate rivet fixed constraint band, restraint strap top
Portion is fixed with velcro, and other end transverse direction fixed board, riser in-plane has arc-shaped slot, and curved scale is arranged at groove top
Line, graduation mark side riser inner plane correspondence restraint strap, screw through arc-shaped slot screw in nut by two sliding block pointers simultaneously
Row, which are slidably matched, to be fixed in riser inner side plane, is had the needle point on down suction, sliding block pointer to point between two sliding blocks and is carved
Line is spent, base plate plane middle part is longitudinally spaced to fix two bearing blocks, and L-shaped axial length end is pointed under riser center parallel across bearing block
Plane, L-shaped axial length end termination is provided with vertical groove, founds tight fit in groove and inserts vertical swing rod, the swing rod other end insert two sliding blocks it
Between down suction, L-shaped axle short end is inserted in elliptical cylinder-shape handle vertically upward, and there is cooperation insertion bottom plate L-shaped axle right angle both sides
Locating piece positioning in plane, constitutes forearm rotation angle measurement device.
Locating piece positioning L-shaped axle short end handle described above is vertically upward.
Vertical swing rod described above has gap with riser inner plane.
The utility model is pasted restraint strap two ends in use, the forearm of measured is placed on bottom plate, with velcro and entered
Row constraint is fixed, the tight handle of holding of measured, keeps handle vertical, when carrying out the measurement of the preceding side of forearm rotation, extracts forearm
The locating piece of preceding side is revolved, measured is rotatable handles, a sliding block pointer is stirred in arc by L-shaped axle rotational band driven fork
Slided in shape groove to transmission direction, the position for pointing to graduation mark by sliding block pointer needle point can read rotational angle.Forearm revolves
Before be measured after, hold swing rod and return to upright position, and then frictionally rests on measured position to sliding block pointer, record is surveyed
After angular values, manual sliding block pointer returns arc central point, and the locating piece that forearm revolves preceding side is inserted into situ, forearm is extracted
The locating piece of supination side, you can the measurement of forearm supinated angle is measured by same step.
The utility model is simple in construction, easy to use, convenient directly to read and record patient forearm's anglec of rotation in real time
Measured value, has reached goal of the invention.
