Technical Field

[0001] The utility model relates to the field of nursing supplies, in particular to a foot pillow for preventing deep vein thrombosis. Background Technique

[0002] Lower extremity venous thrombosis is a common disease, generally referring to the abnormal coagulation of blood in the lower extremity veins, forming a thrombus, hindering the return of venous blood. At this time, it is necessary to perform surgery to implant a lower extremity venous thrombus filter in the patient's lower extremity. In order to protect the patient before and after the surgery, a pillow is usually used to elevate the affected limb of the patient.

[0003] Most of the existing pillows support the patient's calf to achieve the effect of elevating the affected limb. However, the leg lengths and shapes of each patient are different. Using the same pillow for support may not effectively support the popliteal fossa of the patient. In this way, the patient's knee will be under greater pressure. After a long time of support, the patient's knee may be damaged, and the overall support effect of the device is poor. Therefore, a foot pillow for preventing deep vein thrombosis is proposed to solve the above problems. Content of the Utility Model

[0030] Next, in combination with the attached drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 、 Figure 2 and Figure 4 , an embodiment provided by the present utility model: A foot pad and pillow for preventing deep vein thrombosis includes a bottom plate 1 for supporting the overall device. The top end of the bottom plate 1 is hinged with a foot pad 2 for supporting the calf part of the patient. At the front end of the foot pad 2, there is a support assembly 3 for supporting the popliteal fossa part of the patient. The support assembly 3 includes a rotating shaft 31 for supporting the rotation of the support assembly 3. The rotating shaft 31 is fixedly connected to the front end of the foot pad 2. The outer wall of the rotating shaft 31 is rotationally connected with a rotating frame 33 for driving the sponge pad 36 to move. The outer wall of the rotating frame 33 is fixedly connected with a sponge pad 36 for directly contacting the patient's skin. By driving the sponge pad 36 with the rotating frame 33 to support the popliteal fossa of the patient, the pressure on the patient's knee can be reduced, and at the same time, the patient's leg can be prevented from bending. The top end of the bottom plate 1 is provided with an adjusting assembly 4 for adjusting the support angle of the foot pad 2. The adjusting assembly 4 includes a fixed plate 41 for supporting the threaded rod 45. The bottom end of the fixed plate 41 is fixedly connected to the top end of the bottom plate 1.

[0032] Refer to Figure 1 、 Figure 4 and Figure 5The adjusting assembly 4 also includes a threaded rod 45 for driving the slide plate 42 to move. The threaded rod 45 is rotatably connected to the left end of the fixed plate 41. The outer wall of the threaded rod 45 is threadedly connected to the slide plate 42 for squeezing the hinged plate 43. The slide plate 42 can be driven to move left and right by rotating the threaded rod 45. The top of the slide plate 42 is hinged with a hinged plate 43 for transmitting motion. The top of the hinged plate 43 is hinged with a connecting plate 44 for pushing the foot pad 2. The bottom end of the connecting plate 44 is fixedly connected to the bottom end of the foot pad 2. When the slide plate 42 moves to the left, it will squeeze the foot pad 2. The hinged plate 43 is pressed to move it to the left and rotate it. The hinged plate 43 will force the foot pad 2 to rotate upward by pushing the connecting plate 44. The outer wall of the threaded rod 45 is slidably connected to a knob 46 near the left end for facilitating the operator to rotate the threaded rod 45. The top of the base plate 1 is fixedly connected to a rubber block 47 near the left end for fixing the knob 46. The rubber block 47 and the knob 46 are adapted to each other. The knob 46 can be moved to the right to fit with the rubber block 47 by pushing it. When the knob 46 fits with the rubber block 47, the knob 46 will be fixed and cannot rotate.

[0033] Reference Figure 1 - Figure 3 The support assembly 3 also includes a fixing block 34 for fixing the rotating frame 33. The fixing block 34 passes through and is slidably connected to the left end of the rotating frame 33. The top of the fixing block 34 is provided with an inclined surface. When the inclined surface is squeezed, the fixing block 34 will be forced to move to the right. The outer wall of the rotating shaft 31 is provided with a fixing groove 32 for accommodating the fixing block 34. The fixing groove 32 and the fixing block 34 are adapted. When the fixing block 34 is inserted into the fixing groove 32, the rotating frame 33 will be fixed and cannot rotate downward. The right end of the fixing block 34 is fixedly connected to a fixing spring 35 for pushing the fixing block 34. The right end of the fixing spring 35 is fixedly connected to the inner wall of the rotating frame 33. The fixing spring 35 will always push the fixing block 34 to the left. The fixing block 34 is configured to be able to be quickly inserted into the interior of the fixing groove 32. The fixing block 34 is configured to be L-shaped. The front end of the fixing block 34 passes through and is slidably connected to the front end of the rotating frame 33. The fixing block 34 can be driven to move left and right by moving the L-shaped front end of the fixing block 34. The front end of the foot pad 2 is rotatably connected to a buckle 37 for fixing the fixing block 34. The buckle 37 is made of rubber material and has a certain elastic deformation ability. The buckle 37 is configured to be concave in shape. The buckle 37 and the fixing block 34 are adapted. The buckle 37 can be rotated to be sleeved on the outer wall of the fixing block 34, so that the fixing block 34 will not be able to move left and right. This can prevent the patient from accidentally touching the fixing block 34 and causing the rotating frame 33 to fall.

[0034] Working principle: When it is necessary to use the overall device to support the patient's leg, the patient's leg can be first placed on the top of the foot pad 2, and then the knob 46 can be rotated to drive the threaded rod 45 to rotate. The rotation of the threaded rod 45 will drive the slide plate 42 to move left and right. The left and right movement of the slide plate 42 will squeeze the hinge plate 43 to make it move left and rotate. The left movement of the hinge plate 43 will squeeze the connecting plate 44 to make it move upward. The connecting plate 44 will push the foot pad 2 to make it rotate upward. In this way, the support angle of the overall device can be adjusted.

[0035] After the angle adjustment is completed, the rotating frame 33 can be toggled upward to drive the sponge pad 36 to rotate. When the outer wall of the sponge pad 36 squeezes the patient to straighten the leg, the rotating frame 33 can be slowly released. The fixing block 34 will be pushed by the fixing spring 35 and snap into the inside of the fixing groove 32. At this time, the rotating frame 33 will be fixed and cannot rotate. Then the buckle 37 can be rotated to sleeved on the outer wall of the fixing block 34. In this way, the fixing of the rotating frame 33 is realized.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
