[0026] In order to improve the patient's use comfort, in the use process, a soft pad 5 is laid on the lying plate 1, which is designed to provide a more comfortable experience for the patient. The patient's feet, shins and thighs will be placed on three independent air bags 3 respectively. In order to ensure the best use experience, first of all, the three-way valve 41 needs to be opened, and then the air pump 4 is started. The air pump 4 will supply air to each connecting pipe 42 through the three-way valve 41, and the gas will flow into each air bag 3, making it expand to properly support different parts of the patient's lower limbs. These soft air bags 3 can effectively reduce the direct contact between the patient's lower limbs and the lying plate 1, thereby providing a more comfortable support environment. In order to accurately control the inflation degree of each air bag 3, the inflation state of the air bag 3 can be monitored by checking the scale 13, and the identification block 18 moves in real time with the filling state of the air bag 3. By checking the index position of each identification block 18 pointing to the corresponding scale 13, the inflation amount of the air bag 3 can be determined. When the air bag 3 is inflated to the desired state, the three-way valve 41 and the air pump 4 should be closed to stop inflation. For patients who need different support forces, the valve port of the corresponding position on the three-way valve 41 can be closed individually after the air bag 3 reaches the required inflation state, so that the continuous inflation of other air bags 3 is not affected, so that each air bag 3 can maintain different inflation levels according to the specific needs of the patient, thereby achieving the effect of controlling the lifting angle of the lower limbs, providing personalized support angle for the patient's lower limbs, and effectively relieving the pressure of the specific area. In addition, in order to further adjust the position of the patient's lower limbs, the coaxial double-output motor 10 can be started to drive the threaded rod 9 to rotate, which will make the two limit racks 8 on both sides approach each other along the threads of the threaded rod 9, so as to fold the patient's expanded lower limbs. At the same time, the position of the adjusting plate 15 supporting the feet can also be adjusted manually, and the position of the adjusting plate 15 is fixed by inserting the insertion rod 17 into the corresponding insertion hole 16, so as to ensure that the patient's feet are stably supported. After the above adjustment, the position of the patient's lower limbs will be optimized, thereby obtaining a more comfortable and stable support effect.
