Description

Technical Field

[0001] The invention relates to the technical field of coccyx-sacral pressure sore care, and in particular to a pressure relief pad used for coccyx-sacral pressure sore care. Background Art

[0002] Pressure sores are caused by long-term pressure on the body part, which hinders blood circulation and causes tissue necrosis due to lack of nutrition. Pressure sores are most likely to develop from the sacrum to the perineum of patients who have been bedridden for a long time. Once a pressure sore occurs, it will increase the pain of the patient, so active treatment measures should be taken.

[0003] For example, a protective pad suitable for coccyx pressure sores with publication number CN219332129U can adjust the size of the pressure sore hole according to the size of the coccyx pressure sore. Since the wrapping pad does not cover the coccyx pressure sore, it can better change the dressing, and the breathability is more conducive to the treatment of coccyx pressure sores. The wrapping pad has the advantages of no skin allergy, easy use and dressing change, good treatment and rehabilitation effects on pressure sores, etc., and can be used for patients with paralysis, coma, after major surgery, fracture traction, severe burns (frostbite), etc., and is suitable for use in hospitals, nursing homes and home beds. However, in actual use, when changing the dressing on the patient's pressure sore area, it is still necessary to turn the patient over and leave the protective pad as a whole. For example, some patients with fractures are more painful during the movement, and the movement process is more inconvenient, and it is also more inconvenient for nursing staff during the dressing change process. There are certain usage defects.

[0004] Therefore, we propose a decompression pad for coccyx pressure ulcer care to solve the above problems. Summary of the invention

Support components are symmetrically arranged on both sides of the inner part of the pad body. The pad body is supported by a high-density sponge as a whole, which has good elasticity and support. When changing the dressing on the patient's pressure sore area, the knob can be turned to drive the threaded rod to rotate. After the threaded rod is rotated, it can be moved through the threaded connection with the threaded sleeve, so that the circular frame can be driven to slide on the positioning plate. The positioning plate can be positioned by the cooperation of the positioning bar and the positioning groove. After the circular frame moves, it drives the movable rod to move. When the movable rod moves, it drives the movable sleeve to move, and the movable sleeve can compress the telescopic spring, thereby making the connecting rod rotate, so that the connecting rod can push the support plate to move. The support plate is limited by the cooperation of the limit bar and the limit groove, so that the through groove can be propped up, so that the upper support The plate can bear the patient's own gravity, so that the top of the pad body can be lifted up to support the patient's coccyx, the nursing pad is separated from the patient's pressure sore, the nursing pad can be pulled out from the connecting groove, and the dressing can be changed. When placing the nursing pad, the nursing pad is inserted into the connecting groove, and the knob is rotated in the opposite direction to make the two supporting plates close to each other. The pad body is compressed and deformed under the patient's own gravity, so that the top of the pad body moves downward. The position of the two supporting plates is adjusted so that the patient's coccyx contacts the nursing pad, and the rotation of the knob can be stopped, so that the medicine application part on the nursing pad applies medicine to the patient's pressure sore part. The pad body can be supported by the supporting component to avoid the nursing pad being unable to be pulled out of the pad body when changing the dressing, thereby improving practicality. 2. When the right side of the back frame is supported, the movement of the fixing bar can drive the movement of the fixing bar, and the fixing bar can move in close contact with the oblique bar. Since the back frame is limited on the positioning plate, the movement of the fixing bar can exert pressure on the oblique bar, and then exert pressure on the top side of the right lower support plate, which can prevent the pad body from being squeezed by the patient's pressure at one end of the inner connecting groove to deform the connecting groove, and avoid pressing one end of the nursing pad. The back frames on both sides can drive the installation rod to move while moving, and the installation rod can push the U-shaped frame to slide on the installation plate while moving, so that the bottom of the support bar fits with the nursing bed, so that part of the pressure on the pad body can be transferred to the U-shaped frame and the support bar, further preventing the nursing pad from being pressed by the pad body, and avoiding affecting the replacement of the nursing pad. 3. A fixing assembly is provided at one end of the two sets of straps away from the pad body. When fixing the pad body, the overall length of the strap is adjusted so that the suction cups are placed on both sides of the nursing bed, and the connecting block is pulled to drive the sliding rod to move. The reset spring is stretched while the sliding rod moves, and the rotating rod on the rotating support frame drives the horizontal bar to rotate, so that the two ends of the horizontal bar are respectively fitted with the connecting block and the shell, and then the connecting block can be supported and limited, so that the sliding rod is limited, and the movement of the sliding rod drives the piston to move, and the inside of the shell can be evacuated. The air is discharged from the shell through the exhaust hole, so that the suction cup can be closely fitted with the nursing bed under the action of atmospheric pressure. The fixing assembly is convenient for nursing staff to fix the pad body to avoid displacement of the pad body when the patient moves. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Embodiment 1: Figure 1-4As shown, support components 2 are symmetrically arranged on both sides of the interior of the pad body 1. The pad body 1 is supported by a high-density sponge as a whole, and has good elasticity and support. When changing the dressing on the patient's pressure sore area, the knob 216 can be turned to drive the threaded rod 215 to rotate. After the threaded rod 215 is rotated, it can be moved through the threaded connection with the threaded sleeve 214, so that the circular frame 213 can be driven to slide on the positioning plate 202. The positioning plate 202 can be positioned by the cooperation of the positioning bar 203 and the positioning groove 204. After the circular frame 213 moves, it drives the movable rod 205 to move.
