[0027] The present application provides a kind of leg edema relieving device for gestational hypertension patient.

[0028] Embodiment one:

[0029] As Figures 1-3As shown, it includes the base 1, one side of the top of the base 1 is slidably connected with the cushion 2, the other side of the top of the base 1 is fixedly connected with the gable-shaped protective shell 3, the inner wall of the gable-shaped protective shell 3 is fixedly connected with the pressure belt 31, the side of the gable-shaped protective shell 3 away from the cushion 2 is fixedly connected with the support 32, the inside of the support 32 is rotatably connected with the lead screw one 33, the bottom of the gable-shaped protective shell 3 is fixedly connected with the motor one 34, the output shaft end of the motor one 34 is fixedly connected with the end of the lead screw one 33, the motor one 34 can drive the lead screw one 33 to rotate, the outer surface of the lead screw one 33 is threadedly connected with the traction block 4, the two sides of the traction block 4 are fixedly connected with the cross beam 41, one end of the cross beam 41 away from the traction block 4 is fixedly connected with the guide rod 42, the bottom of one side of the gable-shaped protective shell 3 is fixedly connected with the guide groove 35, the guide rod 42 is slidably connected in the guide groove 35, the guide rod 42 guides and supports the traction block 4, the hinge between the guide rod 42 and the traction block 4 is limited by the limiting groove 5, the inside of the limiting groove 5 is rotatably connected with the lead screw two 51, the bottom of the limiting groove 5 is fixedly connected with the motor two 52, the output shaft end of the motor two 52 is fixedly connected with the bottom end of the lead screw two 51, the motor two 52 can drive the lead screw two 51 to rotate, the outer surface of the lead screw two 51 is threadedly connected with the pedal 53, the bottom of one side of the pedal 53 is fixedly connected with the foot rest 54, when the patient uses, the feet can be placed in the inside of the foot rest 54, the lead screw two 51 is driven by the motor two 52 to rotate in the pedal 53, so that the pedal 53 is raised or lowered, so as to lift or put down the leg of the patient, and the limiting groove 5 is hingedly connected with the traction block 4 and the guide rod 42, so when the patient moves the leg up and down, the limiting groove 5 will tilt towards the patient's body, so as to ensure that the ankle is always in a relatively relaxed state, and the comfort is improved.

[0030] Preferably, as Figure 3 As shown, one side of the pedal 53 is fixedly connected with the elastic belt 55, when the feet are placed on the pedal 53, the instep can be inserted into the elastic belt 55 first, and then the heel is placed in the foot rest 54, which can prevent the feet from slipping off the foot rest 54 when the pedal 53 rises or falls.

[0031] The working principle of the embodiment is as follows: in use, after the patient sits on the cushion 2 and puts the lower leg into the gable-shaped protective shell 3, the lower leg is massaged by the inflation and deflation of the pressure belt 31, when the leg needs to be lifted, the motor one 34 is started to drive the traction block 4 to approach the feet, and then the heel is placed on the foot rest 54, the motor two 52 is started to make the pedal 53 rise or fall, so as to lift or put down the feet of the patient, realize the operation of lifting and putting down the leg, move the leg, promote the blood circulation of the lower limbs, and thus help to improve the recovery efficiency of the patient.

[0032] Example two:

[0033] As Figure 2 and Figure 4As shown in Embodiment 1, the seat cushion 2 includes a seat plate 21 and a base plate 22. A positioning shaft 211 is fixedly connected to the bottom of the seat plate 21, and a bearing 221 is provided at the center of the base plate 22. The positioning shaft 211 is rotatably connected to the inside of the base plate 22 through the bearing 221. For pregnant patients, who have difficulty moving, the seat plate 21 is rotatably connected to the base plate 22. When using the cushion, pregnant patients can first sit on the seat plate 21 and then rotate the seat plate 21 so that their lower legs can be placed into the mountain-shaped protective shell 3. This makes it convenient for pregnant patients to use the cushion. A slide bar 222 is fixedly connected to the bottom of the base plate 22. A groove 11 is provided on one side of the top of the base 1. The base plate 22 is slidably connected to the inside of the groove 11 through the slide bar 222. For patients with different leg lengths, the distance between the seat plate 21 and the mountain-shaped protective shell 3 can be adjusted by sliding the base plate 22, thereby ensuring that the lower legs can be accurately placed into the inside of the mountain-shaped protective shell 3.

[0034] The working principle of this embodiment is as follows: When in use, for pregnant patients with mobility difficulties, the seat 21 can be rotated so that its front side faces the base 1. At this time, the pregnant patient can turn around and sit on the seat 21. Then, by turning around and rotating the seat 21, the legs can be placed inside the mountain-shaped protective shell 3. Thus, the pregnant patient does not need to straddle the mountain-shaped protective shell 3 and sit on the cushion 2, which makes it convenient for pregnant patients to use.

[0035] Example 3:

[0036] like Figure 4 As shown, based on Embodiment 2, a cushion 6 is hinged to the rear side of the seat plate 21. A mounting groove 212 is provided on the rear side of the seat plate 21. A drive shaft 213 is rotatably connected inside the mounting groove 212. A worm gear 214 is fixedly connected to the drive shaft 213. A worm wheel 61, meshing with the worm gear 214, is fixedly connected to the bottom of the cushion 6. By rotating the worm gear 214, the worm wheel 61 is driven to rotate, thereby adjusting the tilt angle of the cushion 6. Since the worm wheel 61 cannot drive the worm gear 214 to rotate, it has a self-locking function, ensuring the stability of the patient leaning against the cushion 6. A second worm wheel 215 is fixedly connected to the outer surface of the drive shaft 213. The mounting slot 212 is internally connected to a rotating shaft 216. A worm gear 217 that meshes with a worm wheel 215 is fixedly connected to the rotating shaft 216. The worm gear 217 drives the worm wheel 215 to rotate, thereby rotating the transmission shaft 213. One end of the rotating shaft 216 extends to one side of the seat plate 21, and a handwheel 218 is fixedly connected to the end of the rotating shaft 216. The patient can rotate the rotating shaft 216 through the handwheel 218, thereby driving the worm wheel 61 to rotate, thereby adjusting the tilt angle of the backrest 6. The structure of the worm gear driving the worm wheel has the functions of deceleration and increasing torque, so that the tilt angle of the backrest 6 can be adjusted with a smaller force.

[0037] The working principle of the embodiment is as follows: in use, after the patient sits on the cushion 2, the inclination angle of the back cushion 6 can be adjusted by rotating the hand wheel 218 to drive the worm gear one 61 to rotate, and after the adjustment is completed, the back cushion 6 can provide stable support for the patient after leaning on the back cushion 6, and the problem that the back cushion 6 is caused to fall down by rotating the worm one 214 driven by the worm gear one 61.
