Description

Technical Field

[0001] The utility model relates to the technical field of medical cushions, and particularly relates to an adjustable double lower limb elevation pillow. Background Technique

[0002] For patients with lower limb thrombosis, it is easy to cause high pressure in the lower limb veins and block the blood circulation and return. Due to the blocked blood return, the formation of thrombosis is slow. Hypercoagulable states of blood, such as trauma, after surgery, extensive burns, pregnancy, postpartum, etc., can all increase platelets, enhance adhesiveness, and trigger the formation of lower limb venous thrombosis. Therefore, patients with deep vein thrombosis in the lower limbs should elevate the affected limb to promote blood return. Elevating the lower limbs is beneficial to the blood return of the distal end and can relieve the symptoms of limb edema. Therefore, it is necessary to elevate the affected limb when venous thrombosis occurs.

[0003] Currently, for the way of propping up the legs of patients with leg edema, a W-shaped pillow with a curved bottom is often selected. By placing the legs in the two side grooves of the W-shaped pillow, the purpose of raising the legs is achieved. However, the structure of the current pillows on the market is relatively single, and the distance and height of the two side grooves are not adjustable. Therefore, for patients with different leg shapes, different leg lengths, and different degrees of leg bending limitation, it is impossible to well adapt to the needs of different patients, resulting in discomfort for patients when propping up the legs, which has limitations.

Detailed implementation manners

[0022] To make the objectives, technical solutions and advantages of the utility model clearer, the technical solutions of the utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the scope protected by the utility model.

[0023] Refer to Figures 1 - 3 As shown, the utility model provides an adjustable double-leg elevation pillow, which includes two symmetric sector blocks 1. A rotating connection structure is provided at the lower ends of the two sector blocks 1. A connecting and fixing member 3 for adjusting the included angle between the two is provided on the surfaces of the two sector blocks 1. An inner frame 2 is provided inside each sector block 1. A sponge pad 5 is fixedly connected to the outside of the inner frame 2, and the inner frame 2 and the sponge pad 5 cooperate to form the sector block 1. A mounting plate 11 is provided on the upper side of the sector block 1. A middle plate 7 is fixedly connected to the inside of the inner frame 2. A tension structure for driving the mounting plate 11 to approach the surface of the sector block 1 is provided on the middle plate 7. A supporting structure for driving the mounting plate 11 away from the surface of the sector block 1 is provided on the inner bottom of the inner frame 2. U-shaped pads 14 are fixedly connected to both mounting plates 11.

[0024] Specifically, the rotating connection structure includes a connecting belt 6. The two ends of the connecting belt 6 are respectively connected to the lower ends of the two sector blocks 1, and the connecting belt 6 is made of nylon material, so that the angle between the two sector blocks 1 can be adjusted, thereby realizing the adjustable distance between the two U-shaped pads 14.

[0025] Refer to Figure 2As shown in the figure, the connecting fixture 3 includes a connecting plate 3a. Both ends of the connecting plate 3a are rotatably connected with bolts 3b. A plurality of bolt holes 3c that are threadedly connected with the bolts 3b are formed on the surface of the inner frame 2, and the plurality of bolt holes 3c are arranged linearly and obliquely. When the two sector blocks 1 are rotated to an appropriate distance, the two bolts 3b are simultaneously screwed into the two bolt holes 3c. Since the bolt holes 3c on the two sector blocks 1 are both arranged obliquely, the angle fixation of the two sector blocks 1 can be completed.

[0026] As an optional implementation manner, the tension structure includes two slide rod holes 8 formed on the upper side of the inner frame 2. Slide rods 9 are slidably connected in the two slide rod holes 8. A spring 10 is connected between the lower end of the slide rod 9 and the middle plate 7, and the upper ends of the two slide rods 9 are fixedly connected to the bottom surface of the mounting plate 11. When the slope top block 4b does not contact the rectangular block 13, the mounting plate 11 moves downward under the pulling force of the spring 10, and at the same time, the slide rod 9 slides in the slide rod hole 8.

[0027] Refer to Figure 3 As shown in the figure, the supporting structure includes a rectangular groove 12 formed in the middle of the upper side of the inner frame 2. A rectangular block 13 is sleeved in the rectangular groove 12, and the upper end of the rectangular block 13 is fixedly connected to the mounting plate 11. An adjusting assembly 4 for driving the rectangular block 13 to move upward is provided on the inner bottom of the inner frame 2. Through the movement of the slope top block 4b, it contacts the lower end of the rectangular block 13, and drives the rectangular block 13 to rise in the rectangular groove 12 through wedge fit, so as to realize the adjustment of the height position of the upper mounting plate 11 and the U-shaped pad 14.

[0028] As an optional implementation manner, the adjusting assembly 4 includes a slope top block 4b located on the middle plate 7, and the slope top block 4b is in wedge fit with the lower end of the rectangular block 13. A threaded rod 4a is rotatably connected to the inner bottom of the inner frame 2. A threaded hole 4c that is threadedly connected with the threaded rod 4a is formed on the slope top block 4b. By rotating the threaded rod 4a, the slope top block 4b threadedly connected with it is driven to move and contact the lower end of the rectangular block 13.

[0029] Specifically, the surface of the slope top block 4b is in clearance fit with the middle plate 7, and the lower end of the rectangular block 13 is designed to be arc-shaped, which can make the slope top block 4c move more stably on the surface of the middle plate 7, and at the same time avoid the rotation of the slope top block 4b, so that it stably contacts the lower end of the rectangular frame 13. At the same time, the arc-shaped design of the rectangular block 13 can avoid wear when contacting the slope top block 4b.

[0030] With the above structure, during use, adjust the included angle between the two sector blocks 1 according to the rotational connection structure and fix it through the connecting and fixing member 3. At this time, the distance between the two upper U-shaped pads 14 is also adjusted accordingly. Then, drive the mounting plate 11 away from the surface of the sector block 1 through the supporting structure to drive the upper U-shaped pad 14 to adjust its height. Subsequently, place the two upper U-shaped pads 14 at the knees of both legs for support.

[0031] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
