Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary products, and particularly relates to a pillow for raising lower limb edema. Background Art

[0002] Patients who are bedridden for a long time are prone to deep vein thrombosis. Patients who are bedridden for a long time are prone to deep vein thrombosis, which leads to poor deep vein return. Patients will experience symptoms of lower limb edema. Long-term bed rest will cause edema of the feet. Generally, medical staff will place elevated pillows on the lower limbs to prevent lower limb edema in patients who are bedridden for a long time.

[0003] At present, the existing lifting pillow is not convenient to adjust the lifting height according to the needs of the patient during use, and has poor applicability. Moreover, after long-term use, the lower limbs sweat and the sweat soaks into the pillow, which can easily cause lower limb eczema in patients. Therefore, we propose a lower limb edema lifting pillow. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3 The utility model provides a technical solution for raising the pillow for lower limb edema: it includes a bottom box 1, a pillow pad 4 and a top rod 9. The top end of the bottom box 1 is slidably connected to the top block 3, and the top of the top block 3 is fixedly provided with a pillow pad 4. The two sides of the interior of the bottom box 1 are movably connected with a bidirectional screw 6 through a bearing. Both ends of the bidirectional screw 6 are sleeved with a threaded sleeve 8, and the top of the threaded sleeve 8 is movably connected to the top rod 9. The two ends of the top rod 9 are respectively fixedly connected to the threaded sleeve 8 and the top block 3 through a movable connecting seat 10. One end of the bidirectional screw 6 is fixedly provided with a transmission gear 7, and the end of the bottom box 1 near the knob 12 is provided with a driving gear 11, which is meshed with the transmission gears 7 on both sides.

[0021] Specifically, the outer cover of the pillow pad 4 is provided with a waterproof cloth cover 5 , and the waterproof cloth cover 5 is fixedly covered on the outer periphery of the pillow pad 4 . The surfaces of the pillow pad 4 and the waterproof cloth cover 5 are both provided with arc grooves.
