Description

Technical Field

[0001] This utility model relates to the field of positioning pads, and in particular to an adjustable waist and leg integrated positioning pad. Background Technology

[0002] With the development of clinical medicine and rehabilitation techniques, body positioning devices are increasingly widely used in surgical positioning management, trauma immobilization, and rehabilitation physiotherapy. In spinal diseases, such as lumbar disc herniation, which is often accompanied by radiating pain in the lower back and legs, a lumbar support pillow can maintain the physiological curvature of the lumbar spine, relax the lumbar muscles, and relieve lower back pain. Simultaneously, a leg support pillow can maintain both lower limbs in a 90-degree knee and hip flexion position or a 30-degree knee flexion position, which can relax compressed nerves and relieve radiating pain in the lower limbs. In patients with thoracic and lumbar fractures, using a thoracic and lumbar support pillow can achieve closed reduction through body weight and can also... During the fracture healing process, it plays a stabilizing role, preventing the fracture ends from shifting again and promoting callus formation. At the same time, the leg support pillow helps relieve muscle tension in the chest, waist, and legs, alleviates pain, and improves patient comfort. Traditional positioning cushions mostly adopt a separate fixed design, which has defects such as poor adjustment flexibility, inability to adapt to the needs of patients with different body types, and uneven local pressure distribution, which can easily lead to position-related pressure sores and nerve damage, especially in the context of combined lumbar and leg treatment. Therefore, there is an urgent need to develop an adjustable lumbar and leg positioning cushion that is easy to operate and can flexibly adjust the support position according to the patient, so as to achieve independent and precise adjustment of lumbar and leg support.

[0035] Working principle:

[0036] When using the first adjustment mechanism 4, the first motor 47 is started, and the first motor 47 drives the first transmission rod 43 to rotate. Through the meshing of the first driving bevel gear 44 and the first driven bevel gear 45, the first transmission rod 43 drives the first lead screw 42 to rotate. The rotation of the first lead screw 42 causes the meshing first moving block 46 to move horizontally along the axis of the first lead screw 42. Then, through the first connecting post 23 inserted into the mounting hole of the first moving block 46, the waist support pad 2 is pushed to slide laterally on the surface of the base pad 1. By controlling the forward and reverse rotation of the first motor 47, the position of the waist support pad 2 can be precisely adjusted forward and backward.

[0037] When using the second adjustment mechanism 5, the second motor 57 is started, and the second motor 57 drives the second transmission rod 53 to rotate. Through the meshing of the second active bevel gear 54 and the second driven bevel gear 55, the second transmission rod 53 drives the second lead screw 52 to rotate. The rotation of the second lead screw 52 causes the meshing second moving block 56 to move horizontally along the axis of the second lead screw 52. Then, through the second connecting post 33 inserted into the mounting hole of the second moving block 56, the leg support pad 3 is pushed to slide laterally on the surface of the base pad 1. By controlling the forward and reverse rotation of the second motor 57, the position of the leg support pad 3 can be precisely adjusted forward and backward. At the same time, the second adjustment mechanism 5 is provided with two second lead screws 52 and second moving blocks 56 located on different sides. Depending on the injured limb of the patient, the leg support pad 3 can be inserted into the second moving block 56 on the corresponding side, improving the practical effect.

[0038] When the first motor 47 and the second motor 57 stop working, the first lead screw 42 and the second lead rod automatically lock the positions of the first moving block 46 and the second moving block 56 through the friction of the threads. Even under external force, the waist support pad 2 and the leg support pad 3 will not be displaced, ensuring body stability; at the same time, the first connecting post 23 and the second connecting post 33 are fitted with the mounting holes of the first moving block 46 and the second moving block 56, which not only ensures reliable connection during adjustment, but also allows for quick separation by vertically lifting the waist support pad 2 and the leg support pad 3, facilitating cleaning or replacement of support modules of different shapes.

[0039] Simultaneously, when the height of the lumbar support pad 2 and the leg support pad 3 needs to be adjusted, the first lifting mechanism 24 inside the mounting cavity of the first support body 21 and the second lifting mechanism 34 inside the mounting cavity of the second support body 31 can be controlled. The first lifting mechanism 24 and the second lifting mechanism 34 are electric scissor-type lifting mechanisms, which are common lifting mechanisms in the prior art. The first lifting mechanism 24 and the second lifting mechanism 34 are used to control the lifting of the first support body 21 and the second support body 31, thereby controlling the height adjustment of the lumbar support pad 2 and the leg support pad 3. At the same time, when it is necessary to maintain a 30-degree knee flexion, the end of the second support body 31 with an inclined angle is set towards the lumbar support pad 2. When it is necessary to maintain a 90-degree knee and hip flexion, the right-angle end of the second support body 31 is set towards the lumbar support pad 2. When the patient's legs are in different positions, the second support body 31 can fit closely to the patient's legs, improving comfort.

[0040] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0041] Although this disclosure has been described in detail with reference to exemplary embodiments, it is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of this disclosure.
