Notably, the cross section of the chute is T-shaped; a bearing is arranged between the central shaft of the first bevel gear 3 and the side wall of the shell 2, and a bearing is arranged between the rotating shaft and the side wall of the shell 2; in order to ensure that the screw 5 does not rotate reversely, a one-way clutch can be arranged between the screw 5 and the lower end of the shell 2, when the rotating shaft drives the screw 5 to rotate, the one-way clutch between the screw 5 and the shell 2 idles, and when the rotating shaft and the screw 5 idles, the one-way clutch between the shell 2 and the screw 5 enables the screw 5 not to rotate reversely; in order to prevent the vertical rods 9 from being damaged, the upper ends of the plurality of vertical rods 9 are fixed together through an annular connecting plate, and the front end of the connecting plate is provided with an opening, so that legs can conveniently enter the opening; of course, the small balls 15 or rollers 17 in the massage heads are kept in contact with the leg portions under the action of the pressure spring; the side wall of the arc rod 7 is hinged with a plurality of steel balls in a spherical way, so that the friction between the arc rod 7 and the arc plate 6 is reduced.

For convenience of explanation, and also for reducing resistance when the legs are lifted upwards, it is assumed herein that when the second bevel gear 4 rolls upwards along the first bevel gear 3, the rotating shaft on the second bevel gear 4 and the lead screw 5 idle; when the foot rotates clockwise, the pedal 21 can drive the planet carrier 12 to rotate, and when the foot rotates counterclockwise, the pedal 21 and the planet carrier 12 idle.

When the device is used, a patient places thighs in the U-shaped plate 1, the knees are located between the two shells 2, feet are placed on the pedals 21 and bound by a binding belt, then the feet are lifted upwards, the second bevel gear 4 rolls upwards along the first bevel gear 3, and the second bevel gear 4 idles; when the shank falls downwards, second bevel gear 4 rolls downwards along first bevel gear 3, second bevel gear 4 drives the pivot and rotates, the pivot drives lead screw 5 that corresponds rather than through the one-way clutch on it and rotates, lead screw 5 rotates and drives the slide cartridge on it and reciprocate, two slide cartridges drive arc 6 through arc pole 7 about and reciprocate, a plurality of massage heads move along shank axis direction when arc 6 reciprocates, so reciprocal, slide cartridge reciprocates along reciprocating lead screw 5's axial, realize the vertical massage to the shank.

When massage area needs to be adjusted, the bottom plate 20 is stably arranged on the bottom surface, then the legs are kept still, the foot soles are swung left and right, the pedal 21 swings left and right, the pedal 21 drives the planet carrier 12 to rotate through the one-way clutch on the pedal, the planet carrier 12 drives the gear ring 22 to rotate, the gear ring 22 drives the annular plate 8 to rotate through the support rods 11, the vertical rods 9 rotate along the annular plate 8, the vertical rods 9 drive the arc plate 6 to rotate along the arc rod 7 through the massage heads, circumferential rotation of the massage heads on the legs is achieved, adjustment of abnormal massage is achieved, then leg lifting and falling actions are repeated, and timely massage is conducted on muscles while resistance movement is achieved.

For a patient who cannot get out of bed, passive movement is adopted, manual operation is needed by medical staff, when the device is used specifically, the patient takes a lying position, thighs of the patient are placed in a U-shaped plate 1 in the device, feet of the patient are placed on a pedal 21, the feet of the patient are fastened by a binding belt, then the medical staff holds the U-shaped plate 1 with one hand and supports the U-shaped plate upwards to a proper position and keeps the U-shaped plate still, the feet or a gear ring 22 or a circular plate 19 or a bottom plate 20 are dragged by the other hand, the shanks swing up and down, and the second bevel gears 4 roll on the first bevel gears 3, so that massage is finally realized; when the massage area needs to be adjusted, the lower legs of the patient are completely suspended, then the circular plate 19 is held by one hand, the bottom plate 20 is rotated by the other hand, the bottom plate 20 rotates to drive the gear ring 22 to rotate through the sun gear 10, the gear ring 22 rotates to drive the plurality of massage heads to rotate along the circumferential direction of the legs through the vertical rods 9, so that the adjustment of the massage area is realized, and under the state, the bottom plate 20 is rotated all the time, and the circumferential massage of the plurality of massage heads on the legs can be realized.

The invention has the outstanding advantages and remarkable progress that:

1. compared with the prior art, the leg nursing massage device has the advantages that the legs, particularly the crus, of a patient can be massaged timely while the joints of the lower limbs of the patient are moved, and the treatment and the efficiency of leg nursing of the patient are greatly improved.

2. The invention combines the actual situation, adopts a full mechanical form, particularly adopts a reciprocating screw rod 5 mechanism, can adapt to the appearance characteristic of the slender leg, can scrape and rub the outer surface of the shank back and forth in the vertical direction as much as possible, has the bionic characteristic, can press blood, promotes the blood flow of the leg and prevents the formation of thrombus.

3. When the leg-lifting massage device is used, a patient lifts the leg upwards, the one-way clutch between the rotating shaft and the lead screw 5 idles, the burden of the patient when the patient lifts the leg can be effectively relieved, particularly the patient who can just go down, when the leg descends, the rotating shaft can drive the lead screw 5 to rotate by utilizing the self-weight of the leg-lifting massage device and the leg, and the massage head presses the surface of the leg and moves up and down along the leg, so that the blood circulation of the leg is promoted.

4, the invention has diversified using modes and diversified applicable environments, can realize resistance training of patients, can also meet the use requirement of severe patients on beds, and can also be used as a common massage tool to meet the massage requirement on the legs of the patients.

5. The invention is convenient to use, the patient can select the degree of lifting the leg upwards according to the self condition, no matter how high the leg is lifted, the massage distance of the massage head in the vertical direction is not influenced from the upper time, the massage head can always massage the lower part of the leg from the upper part of the leg, and then massage the upper part of the leg from the lower part of the leg, thereby being convenient to use.

6. According to the invention, the one-way clutch is arranged between the pedal plate 21 and the planet carrier 12, so that the massage heads can massage the periphery of the leg at any angle, the circumferential movement of the massage heads is realized, the massage area is convenient to adjust, and the circumferential massage on the leg can be realized when the joint of the foot is moved.

7. When the massage device is specifically implemented, the massage head has various forms, the most suitable two forms are listed in the scheme, one form is that the small ball 15 installed by adopting a spherical hinge is contacted with the leg, the massage device is simple and easy to use, the small ball 15 is approximately in point contact with the leg, the resistance is small, the contact area is small, and the massage device is flexible in specific application; the other is that a roller 17 which can roll on the leg is adopted, and small wheels are arranged on the roller 17, so that the friction of the roller 17 on the circumference of the leg during massage is reduced, the structure is slightly complicated, the roller 17 is in line contact with the leg, the contact area is large, the resistance is correspondingly large, but the massage efficiency is high. In conclusion, the two ways are different in autumn, and can be selected according to practical situations.
