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.

Summary of the invention
The Lower limb bone that the present invention is intended to help medical personnel or research worker to detect better, more easily the patient and the joint of the lower extremity biological respinse under certain compressive stress condition provides a kind of lower limb compressive stress charger.
Lower limb compressive stress charger is provided with the drawing mechanism of the bandage base plate slip relative to the pulling step tread of base plate, step tread, fixing human.The bandage of fixing human can be set to various structures, is mainly used to the health of immobilized patients.Step tread and base plate are slidingly connected, and step tread and base plate can adopt the multiple mode that is slidingly connected, and the present invention adopts and is provided with the twice chute at base plate, and the step tread lower end is provided with the mode that is slidingly connected of slide block.The drawing mechanism that the relative base plate of pulling step tread slides can adopt various structures, adopts pulling force rope and hoist engine structure here, and an end of pulling force rope is connected with step tread, and the other end links to each other with hoist engine.In described pulling force rope, also be provided with a strain gauge measuring device.The handle of medical personnel or the rotatable hoist engine of research worker drives step tread by pulling force rope, and with the direction pulling of step tread to head, the dynamics size of pulling step tread all can be controlled with the time.The large I of compressive stress that lower limb are applied directly reads by the strain gauge measuring device, and the large I of compressive stress is controlled by rotating hoist engine.
The step tread of lower limb compressive stress charger is connected the drawing mechanism that connection and the relative base plate of pulling step tread slide and can also is with base plate: be provided with the twice chute at the base plate middle part, the twice chute is the dovetail structure, be provided with one slide-plate in twice dove-tail form chute, step tread is slidingly connected by slide plate and base plate; The drawing mechanism that the relative base plate of described pulling step tread slides is comprised of screw mandrel, screw handle, screw mandrel support, strain gauge measuring device, quantifier suspension ring, pulling force rope and pulley.Screw handle and screw mandrel are fixed on base plate one end by the screw mandrel support, and screw mandrel is connected with the strain gauge measuring device by the quantifier suspension ring; The middle part of base plate is provided with two fixed pulleys, and the base plate beginning is provided with a fixed pulley, strain gauge measuring device lower end with pulling force rope walk around fixed pulley and be connected with step tread.The rotary screw rod handle drives step tread by pulling force rope and spurs to cephalad direction, and the dynamics size of pulling step tread all can be controlled with time length.The large I of compressive stress that lower limb are applied directly reads by the strain gauge measuring device, and the large I of compressive stress is controlled by promoting screw mandrel.
The invention has the beneficial effects as follows: by quantitatively applying compressive stress to patient's single lower limb, make lower limb be in a constant compressive stress environment, thereby make things convenient for medical personnel or research worker further to detect Lower limb bone and the biological respinse of joint of the lower extremity under certain compressive stress condition, such as articular cartilage strain and viscoelasticity change, union of fracture state etc., make things convenient for medical personnel to the timely diagnosis and treatment of patient.

Specific embodiment
The present invention will be further described below in conjunction with accompanying drawing.
Embodiment 1:
As shown in Figure 1, a kind of lower limb compressive stress charger is provided with bandage 4, pulling force rope 2, strain gauge measuring device 3 and the hoist engine 7 of base plate 6, step tread 1, fixing human.Be provided with twice chute 5 in the front of base plate, the below of step tread is provided with two slide blocks, and slide block embeds chute, so that base plate and step tread are slidingly connected.One end of pulling force rope is connected with step tread, and the other end is connected with hoist engine, and the place also is provided with the strain gauge measuring device in the middle of described pulling force rope.
During use, the patient lies low, and foot is placed on the step tread, and sole and step tread fit tightly, and the bandage of fixing human is tied up in loins, fixes patient's the lower part of the body, makes base plate be stabilized in patient's shank, prevents that base plate from sliding.Rotate the hoist engine handle, by pulling force rope pulling step tread, step tread is spurred to cephalad direction, patient's single lower limb is carried out load on.The large I of compressive stress that patient's lower limb are applied directly reads by the strain gauge measuring device, and controls the compressive stress size that the patient is applied by rotating hoist engine.
Embodiment 2:
As shown in Figure 2, a kind of lower limb compressive stress charger is provided with bandage 11, screw mandrel 12, screw handle 9, screw mandrel support 8, strain gauge measuring device 10, quantifier suspension ring 13, pulling force rope 7 and the pulley 4(5 of base plate 1, step tread 2, fixing human, 6).Be provided with the twice chute at the base plate middle part, the twice chute is the dovetail structure, is provided with one slide-plate in twice dove-tail form chute, and step tread is slidingly connected by slide plate and base plate.Screw handle and screw mandrel are fixed on base plate one end by the screw mandrel support, screw mandrel is connected with the strain gauge measuring device by the quantifier suspension ring, the middle part of base plate is provided with two fixed pulley 4(5), the base plate beginning is provided with a fixed pulley 6, strain gauge measuring device lower end with pulling force rope walk around fixed pulley and be connected with step tread.
