Description

The multifunction traction device

This utility model belongs to a kind of medical treatment and human body recovery apparatus, particularly a kind of multifunction traction device that is used for intervertebral disk hernia, cervical vertebra, orthopaedics and beauty parlor's cervical traction.Especially being fit to patient or patient uses in family therapy and rehabilitation.

At present, because the intervertebral disk hernia patient is in continuous increase, the especially intervertebral disk hernia that causes because of professional reason, women's childbirth, lumbar muscle strain or other many reason, cervical spondylosis and need the people of beauty treatment cervical vertebras (neck) more and more.These patients and part orthopaedics patient often all need carry out traction therapeutic, and all must carry out general every day, and need to continue more than half a year.Its therapeutic modality one is that hospital or beauty parlor utilize extension table to carry out traction therapeutic; The 2nd, adopt domestic suspended block formula traction apparatus in family therapy.Though the former treatment and rehabilitation efficacy are all better, the extension table complex structure is purchased and the cost of use height, and expending of time also is difficult to bear concerning on-the-job personnel grade; Though and latter's acquisition cost is relatively low, also being fit to family uses, but exist traction apparatus more intense to the selectivity of bed, generally being only limited to spring bed could use, and relying on suspended block or counterweight to produce pull strength, its dynamics is difficult to control, adjusts also extremely inconvenient, traction effect is poor, thereby also directly has influence on patient's treatment and rehabilitation.

The purpose of this utility model is a kind of multifunction traction device of design, to overcome that background technology exists or complex structure, to purchase and the use cost height, is not suitable for family and uses; Or disadvantages such as the adjusting of use and pull strength, control inconvenience, traction and therapeutic effect difference; To reach simple in structure, adaptability is strong, and pull strength is easy to adjust, reliable, and therapeutic effect is better, and is easy to use, reduces purposes such as production and use cost.

Solution of the present utility model is that traction apparatus is designed to relatively independent traction frame and fixed mount two parts, adopts screw rod, nut sleeve as force application mechanism; Pull rope is directly fixed on nut sleeve or is fixed on the traction cross bar that links into an integrated entity with nut sleeve, screw rod is fixed on the main cross bar by its fixed bar and cramp bar activity, on main cross bar, also establish pulley yoke, traction frame by connecting rod be located at uses that link into an integrated entity of adapter sleeve and fixed mount on the fixed mount, also be provided with the mouth of growing that is connected with bed head frame (plate) on the fixed mount and reach fixedly hook; Whole traction apparatus is connected use by pull rope with hook on all kinds of traction belts that are fixed in human body.Therefore, this utility model comprises traction apparatus body and force application mechanism thereof, pull rope; Key is that this traction apparatus body comprises traction frame and fixed mount thereof; Wherein traction frame comprises main cross bar, is located at the pulley yoke of screw rod on the main cross bar and rocking arm thereof, cramp bar, connecting rod, band pulley and the screw rod fixed bar that cramp bar and screw rod are fused, the traction cross bar of band traction hook, nut sleeve; Traction cross bar and nut sleeve are tightened to one and flexibly connect by sliding sleeve and cramp bar, cramp bar, connecting rod and pulley yoke all are tightened to one with main cross bar, screw rod then is connected (only rotatable) respectively with main cross bar and screw rod fixed bar axial restraint, the screw rod fixed bar then is tightened to one with cramp bar; Fixed mount then comprises bayonet socket, hook and hook regulating handle, is anchored on adapter sleeve and hook regulating handle cover on the fixed mount; Hook is connected by soft band or rope with its regulating handle, and whole traction frame then is integral by being fastenedly connected with it behind the adapter sleeve on the connecting rod insertion fixed mount, and pull rope then is hung in the hook of traction cross bar.Orthogonal two cover adapter sleeves are established in the vertical or horizontal use of traction frame for convenience on fixed mount.And described cramp bar both can be symmetrical arranged two with screw rod, also can only be provided with one in screw rod one side; When a cramp bar only was set, the both sides pull rope can directly be hung on and save the traction cross bar on the nut sleeve.And described pulley is divided into main cross bar both sides, and every side both can be single-sheaved block, also can be assembly pulley.And described pull rope also can be set up one (spring) strain gauge respectively at two traction ends, so that accurately control and regulate its pull strength.

It is easy to adjust, accurate to the utlity model has pull strength, and can carry out step-less adjustment to required pull strength according to different patients' concrete condition and same conditions of patients situation of change; Simple in structure, installation, easy to use, reliable that traction apparatus itself has again both had been suitable for spring bed and had used, and also was suitable for the yoke bed of bed head frame; Both can erect use, but the also horizontal use of level, and also production and use cost are low.Therefore, the utlity model has simple in structurely, easy to install, reliable, pull strength is easy to adjust, accurate, produce and use cost low, adaptability is strong, especially is fit to characteristics such as family's use.
