Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary devices, specifically relating to a postoperative pressure relief device. Background Technology

[0002] Following liver and gallbladder surgery, patients often experience pain at the surgical site and discomfort during the recovery process, especially during the postoperative bed rest period. Therefore, pressure-avoidance care of the wound area is crucial. Liver and gallbladder surgery typically involves vital internal organs, resulting in large surgical wounds and a relatively slow recovery process. During recovery, patients need to remain in bed for extended periods, maintaining a specific posture.

[0003] Post-operatively, patients often cannot effectively prevent blankets from applying excessive pressure to the incision. Furthermore, many traditional post-operative pressure relief devices involve binding protective shields or pads around the incision to avoid pressure. However, these shields are often fixed and cannot be flexibly adjusted according to the patient's body size or the location of the incision, easily leading to pressure sores and other skin injuries.

[0004] Therefore, this invention provides a postoperative pressure relief device. Utility Model Content

[0037] Example 2

[0038] The operating principle of this utility model:

[0039] When using this device to protect the surgical incision of a patient after hepatobiliary surgery from pressure, first move the device to the patient's bedside. Medical staff press the limiting rod 32 at the first rotating rod 14. At this time, the spring 33 is compressed, and the front end of the limiting rod 32 disengages from the limiting groove 311, releasing the limitation on the first rotating rod 14. Rotating the first rotating rod 14 forward and backward causes the lifting screw 133 to rotate up and down along the sliding sleeve 131 through the meshing transmission between the two bevel gears, causing the fixed block 132 and the connected lifting rod 122 to move up and down. The height of the lifting rod 122 can be adjusted according to the patient's size and needs. After the height adjustment is complete, release the limiting rod 32. Under the rebound action of the spring 33, the front end of the limiting rod 32 inserts into the limiting groove 311, fixing the first rotating rod 14 and ensuring the stability of the lifting rod 122.

[0040] Next, the medical staff releases the limit of the second rotating rod 23 according to the above operation, and rotates the second rotating rod 23 to make the forward and reverse threaded rod 222 start to rotate. The rotation of the forward and reverse threaded rod 222 drives the sliders 223 on both sides to slide synchronously. As the sliders 223 move synchronously, the connecting frame 224 also opens or closes, while the sliding plate 221 slides up and down along the suspension 212. This process directly adjusts the distance between the gripper pieces 24, thereby changing the size of the internal space after the quilt is clamped to adapt to the patient's body shape and incision position.

[0041] After the spacing is adjusted, the medical staff repositions the second rotating rod 23 to ensure that the gripper 24 is fixed in place. Next, the gripper 24 will clamp and lift the blanket, creating appropriate space inside the blanket. By adjusting the spacing between the grippers 24, the size of the space inside the blanket can be effectively adjusted, ensuring that the blanket does not exert excessive pressure on the patient's incision, thus providing effective postoperative pressure protection.
