Embodiment 1

[0011] Such as figure 1 As shown, a lower limb compressive stress loading device is provided with a base plate 6, a pedal 1, a strap 4 for fixing the human body, a tension rope 2, a tension gauge 3 and a hoist 7. The front of base plate is provided with two chute 5, and the bottom of pedal is provided with two slide blocks, and slide block is embedded in chute, makes base plate and pedal slide connection. One end of the tension rope is connected with the pedal, and the other end is connected with the winch, and a tension meter is also arranged in the middle of the tension rope.

[0012] When in use, the patient lies down, puts the feet on the pedals, the soles of the feet are closely attached to the pedals, and the straps that fix the human body are tied around the waist to fix the lower body of the patient so that the bottom plate is firmly on the patient's legs , to prevent the bottom plate from sliding. Turn the handle of the hoist, pull the pedal pedal through the tensio...

Embodiment 2

[0014] Such as figure 2 As shown, a lower limb compressive stress loading device is provided with a bottom plate 1, a pedal 2, a strap 11 for fixing the human body, a screw rod 12, a screw rod handle 9, a screw rod bracket 8, a tension gauge 10, and a gauge ring 13. Tension rope 7 and pulley 4 (5,6). There are two chute in the middle of the bottom plate, the two chute are dovetail structure, a slide plate is arranged in the two dovetail chute, the pedal is slidingly connected with the bottom plate through the slide plate. The screw handle and the screw are fixed on one end of the bottom plate through the screw bracket, and the screw is connected with the tension gauge through the gauge ring. There are two fixed pulleys 4 (5) in the middle of the bottom plate, and a fixed pulley 6 at the beginning of the bottom plate. The tension rope that the tension meter lower end has is connected with the foot pedal by going around the fixed pulley.

[0015] During use, the patient lies ...

Abstract

The invention discloses a compressive stress loading device for lower limbs. The compressive stress loading device for lower limbs is provided with a bottom board, a foot board, a strap for fixing a human body, and a tensile mechanism for pulling the foot board to slide relative to the bottom board. The tensile mechanism for pulling the foot board to slide relative to the bottom board is provided with a tension meter. The compressive stress loading device for lower limbs mainly functions in applying certain compressive stress to lower limb bones and lower limb joints of a patient to maintain the lower limbs under constant compressive stress, so that medical workers or scientific researchers can further conveniently test biological responses of the lower limb bones and lower limb joints under the certain compressive stress, such as change in joint cartilage stress and viscoelasticity, fracture healing state and the like. Magnitude and duration of the compressive stress are controllable, the magnitude of the applied compressive stress can be directly read through the tension meter, and the magnitude of the compressive stress can be controlled through the tensile mechanism.

Description

technical field [0001] The invention relates to a biomedical scientific research equipment, in particular to a compressive stress loading device for lower limbs. Background technique [0002] In the treatment of medical treatment, mastering the biological response of the bones and joints of the lower limbs of the human body under certain compressive stress conditions plays an important role in the treatment of some diseases. Existing medical instruments cannot easily help medical personnel or researchers detect the biological responses of patients' lower limb bones and lower limb joints under certain compressive stress conditions, such as articular cartilage strain and viscoelastic changes, fracture healing status, etc. Contents of the invention [0003] The invention aims to help medical personnel or researchers to better and more conveniently detect the biological response of patients' lower limb bones and lower limb joints under certain compressive stress conditions, an...
