Description
Technical field
This utility model relates to a kind of multipurpose medical treatment traction apparatus.
Background technology
The traction apparatus that is applied to the medical skill aspect at present mainly contains following several form and constitutes: taenidium rod-type, simple ratchet tight rope formula, spring are drawing etc., though they can both play certain draw, still have many shortcomings.Such as the traction apparatus of taenidium rod-type and simple ratchet tight rope formula, when drawing for physical activity position (as cervical vertebra, lumbar vertebra), nominal value of thrust usually can change significantly because of the biomechanics tensile force of human body and devalue; The drawing traction apparatus of spring equally also can obviously increase nominal value of thrust on foot because of the biomechanics tensile force change of human body or become zero.Therefore have influence on the traction therapeutic effect.
Summary of the invention
The purpose of this utility model provides a kind of improved multipurpose medical treatment traction apparatus, it can prevent to cause in the hauling distance limit imbalance of rated drawbar pull effectively, the size that can show rated drawbar pull again intuitively, can also in traction state, regulate pull strength on demand at any time by user oneself, and it is permanent steady to remain value of thrust.
The purpose of this utility model is achieved in that using Archimedes's lever principle organically combines into a kind of multipurpose medical treatment traction apparatus with ratchet-type tight rope device.This device external form is a bracket shell, and its inside is provided with ratchet-type euphroe, active type lever device, outlet turning fixed pulley and contact steel wire rope.
(1) bracket shell is at first fixing used for internal structure, and secondly bedplate is provided with preformed hole and inserts and carve side plate, conveniently with equipment combinations such as chair, bed, framves.
(2) the ratchet-type euphroe is to be equipped with handwheel, ratchet, bearing up pulley and corresponding check pawl in same rotating shaft successively.
(3) floating type leverage is provided with the combination arm of force, is provided with successively in a fixing sled point tip axle, portable fulcrum slide block, the slide block fulcrum movable pulley is housed, slide block connects with the readjustment handwheel that sled point is held, and the readjustment handwheel is provided with weight and identifies; The outer arm of force end inside of fulcrum is provided with chain wheel set, and chain wheel set is equipped with trimming hand wheel, chain drum, and chain, standard test weight are fixed on the chain, and the weight sign is arranged on the arm of force corresponding with counterweight.
(4) contact steel wire rope one end is fixed on the bearing up pulley, passes the fulcrum movable pulley in the arm of force end fulcrum slide block successively, passes the fixed pulley that turns to of bracket shell top front end then, stretches out with the traction object to connect.
Description of drawings
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is that the master according to a kind of multipurpose medical treatment traction apparatus that the utility model proposes looks sketch map.
Fig. 2 is the schematic top plan view according to a kind of multipurpose medical treatment traction apparatus that the utility model proposes.
The specific embodiment
Describe details and working condition in detail below in conjunction with accompanying drawing according to the concrete device that the utility model proposes:
A kind of multipurpose medical treatment traction apparatus as shown in Figure 1 and Figure 2 mainly comprises bracket shell (1), gusset piece (2), ratchet-type euphroe (3), floating type leverage (4) and contact steel wire rope formations such as (5).
As shown in Figure 1 and Figure 2, ratchet-type euphroe (3) is positioned at bracket shell (1) upper back, is equipped with handwheel (6), ratchet (7), bearing up pulley (8) and corresponding check pawl (9) in same rotating shaft successively; Floating type leverage (4) is positioned at bracket shell (1) middle and lower part, it is provided with the combination arm of force (10), is provided with successively to be equipped with in a fixing sled point tip axle (11), adjustable portable fulcrum slide block (12), the slide block (12) that fulcrum movable pulley (13), slide block connect readjustment handwheel (14), readjustment handwheel (14) dish is provided with the weight sign; The combination arm of force (10) other end is provided with the sprocket wheel combination, and chain wheel set attaches together be furnished with trimming hand wheel (15), chain drum (16), chain (17), is fixed with standard test weight (18) on the chain, and the combination arm of force (10) corresponding with counterweight (18) is provided with weight and identifies (19).
As shown in Figure 1 and Figure 2, contact steel wire rope (5) one ends are fastened on the bearing up pulley (8), pass the fulcrum movable pulley (13) in the combination arm of force (10) end fulcrum slide block (12) successively, that passes the preceding upper end of bracket shell (1) then turns to fixed pulley (20), stretches out and draws object and connect.
During use, at first this utility model level is connected on the equipment such as chair, bed, frame, will gets in touch steel wire rope (5) and connect with required traction object.When implementing first kind of scheme, counterweight (18) or readjustment handwheel (14) are transferred to predetermined indicated weight, compress check pawl (9) after, the handwheel (6) of rotating ratchet formula euphroe (3), make the combination arm of force (10) rise to level, promptly realized predetermined pull strength.When traction finishes, unclamp check pawl (9) and can remove traction state.
When implementing second kind of scheme, only need at (promptly in traction realization state) on the basis of implementing first kind of scheme, readjustment handwheel (14) or the trimming hand wheel (15) on the arm of force (10) made up in rotation respectively, counterweight (18) or fulcrum slide block (12) are moved forward and backward, promptly change (power X power arm two resistance X resistance arms) lever balance force rate, obtained new rated drawbar pull value on demand.If the traction object is telescopic variation slightly, the combination arm of force (10) can fluctuate in limit range, and the instantaneous acquisition dynamic compensation of pull strength is also kept permanent steady.The way of avoiding pull strength to transfinite is grasped the elasticity of tight rope handwheel (6) exactly, allows the combination arm of force (10) remain at level, notices that this point is not so difficult, because the combination arm of force (10) is very showy directly perceived.
This utility model has been used lever balance theories such as wheel shaft, pulley dexterously, so operate freely lightly, can extensively satisfy medical treatment traction and otherwise needs.
