Furthermore, in the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.
Referring to fig. 1-4, the present invention provides a technical solution:
the utility model provides a knee joint postoperative function exercise device, including the twice slide 1 that sets up side by side, be equipped with spout 11 on the slide 1, all be equipped with the spacing slide rail 12 in side on the both sides inside wall about spout 11, the rule is equipped with a plurality of groovess holes 13 on the tank bottom surface central line of spout 11, it has bracing piece 2 to be close to front end department between the twice slide 1 through the bolt fastening, be equipped with footboard post 3 directly over the spout 11 inboard, the bottom of footboard post 3 is rotated through shaft 41 and is connected with pulley 4, it has connecting rod 5 through the bolt fastening to be close to upper end department between two footboard posts 3, the rear end of connecting rod 5 is equipped with stretching strap 6, one side that connecting rod 5 was kept away from to footboard post 3 is rotated through pivot 72 and is connected with sole pedal 7.
In this embodiment, the width of the notch of the side limiting slide rail 12 is equal to the outer diameter of the wheel axle 41, so that the wheel axle 41 can be just clamped in the side limiting slide rail 12 to slide back and forth.
Furthermore, a plurality of limiting recesses 121 are regularly arranged on the inner side wall of the bottom surface of the side limiting slide rail 12, and the inner diameter of the arc of the limiting recess 121 is matched with the outer diameter of the axle 41, so that the axle 41 can slide downwards into the limiting recesses 121 when sliding to the limiting recesses 121.
Specifically, both ends of the limiting recess 121 are smooth circular arcs, so that the wheel shaft 41 can slide in and out conveniently.
Furthermore, the number of the limiting recesses 121 is equal to that of the slot holes 13, and the positions of the limiting recesses 121 correspond to those of the slot holes 13 one by one, so that when the pulley 4 is temporarily clamped at the slot holes 13, the two ends of the wheel shaft 41 are just clamped into the limiting recesses 121 corresponding to the positions.
In this embodiment, a plurality of angle marks 131 are regularly arranged on the outer side wall of one side of the slideway 1 far away from the support rod 2.
Further, the angle marks 131 are equal in number and in one-to-one correspondence with the positions of the slot holes 13.
Specifically, one of the angle marks 131 is 90 °, and when the patient exercises, the pulley 4 is stopped at the slot hole 13 corresponding to the 90 ° mark, the patient keeps a sitting posture, the legs are bent to 90 °, and the lower legs are vertically placed on the two sole pedals 7.
The distance between the front slotted holes 13 from back to front is increased in sequence at the slotted holes 13 corresponding to the 90-degree mark, and the distance between the rear slotted holes 13 from front to back is increased in sequence.
Specifically, when the lower leg of the patient is perpendicular to the slotted hole 13 corresponding to the angle mark 131 of 90 degrees, the height of the knee of the normal adult is 40-50 cm, and the angle between the straight lines from the two adjacent slotted holes 13 to the knee is 10 degrees, so that the knee bending exercise angle of the patient can be intuitively judged through each angle mark 131.
In this embodiment, the bottom surface of the slideway 1 is fixed with a plurality of anti-slip strips 14 at equal intervals by screws, so that the anti-slip strips 14 are firm and stable, and the device is not easy to slide or shift when placed on the ground.
Specifically, the cleats 14 are preferably made of high-quality silicone rubber.
In this embodiment, two mounting blocks 31 are welded and fixed to the bottom end of the pedal post 3 side by side.
Further, the axle 41 is fixedly inserted in the middle of the pulley 4, so that the axle 41 is firmly and stably connected with the pulley 4, and the axle 41 can roll along with the pulley 4.
Furthermore, two ends of the wheel shaft 41 respectively penetrate through the two mounting blocks 31 and extend into the side limiting slide rails 12 on the two sides, so that the wheel shaft 41 is rotatably connected between the two mounting blocks 31 to facilitate rolling, and the wheel shaft 41 moves back and forth along the side limiting slide rails 12.
Specifically, the length of the axle 41 is less than or equal to the distance between the bottom surfaces of the two side limiting sliding rails 12 corresponding to the position, so that the axle 41 can be clamped between the two side limiting sliding rails 12 and cannot be easily loosened.
Further, the outer diameter of the pulley 4 is larger than the aperture of the top surface of the groove hole 13, so that the situation that the pulley 4 is clamped into the groove hole 13 too much to be separated easily due to the fact that the aperture of the groove hole 13 is too large is avoided.
In this embodiment, the both ends of stretching strap 6 are respectively through the fix with screw at the rear wall of connecting rod 5, make stretching strap 6 durable firm, and the patient holds stretching strap 6 with both hands, is convenient for pull back the connecting rod 5 that pushes away the front end to the side of the body.
In this embodiment, the middle of the sole pedal 7 is provided with a groove 71, and the width of the groove 71 is matched with the width of a sole of an adult male, so that the sole of a patient can conveniently pedal.
Furthermore, the inner bottom surface of the groove 71 is provided with a plurality of raised strips 711 at equal intervals, so that the friction between the bottom surface of the groove 71 and the sole of a patient can be effectively increased, and the foot slippage during use can be avoided.
Specifically, the foot sole pedal 7 is rotatably connected, so that the foot sole can drive the foot sole pedal 7 to rotate according to the extension direction of the lower leg in the knee bending exercise process of the patient, the position of the foot sole is comfortable, and the ankle of the patient can be prevented from being sprained in the exercise process.
When the knee joint postoperative function exercising device of the utility model is used, firstly, the device is placed at the front side of a seat which is highly suitable for the height of a patient, the patient is ordered to sit upright, the thigh is kept horizontal, the shank is vertical, the patient treads two soles on two sole treading plates 7 respectively, and both hands hold a drawstring 6, the patient treads the sole treading plates 7 to push sliding 4 to slide back and forth, each time when a pulley 4 rolls to a groove hole 13, the pulley needs to stay for several seconds, the patient is ordered to feel the feeling of the knee, if the patient is uncomfortable, the pulley does not extend forwards or bend backwards, if the patient is not uncomfortable, a slight force is applied to make the pulley 4 deviate from the device to continue the back and forth movement, the angle of the bent knee is recorded every time, when the pulley 4 rolls to the front end of the device and the legs of the patient are powerless to take the pulley 4 back to the original position, the pulley 4 can be pulled back to the body side through the drawstring 6, when the exercising degree of the bent knee of the patient can reach 90-100 degrees, it is judged that it can meet the discharge standard.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. The technical personnel of this trade should understand, the utility model does not receive the restriction of above-mentioned utility model, and what describe in above-mentioned utility model and the description only does the preferred example of the utility model to need not restrict the utility model, under the prerequisite that does not deviate from the spirit and scope of the utility model, the utility model discloses still can have various changes and improvement, these changes and improvement all fall into the scope of the utility model that claims.
