Description

Technical Field

[0001] The utility model relates to the technical field of postoperative nursing equipment, in particular to an auxiliary rehabilitation device after femoral artery puncture. Background Art

[0002] The femoral artery puncture site is often located on the inner side below the inguinal ligament. Compression and hemostasis of the puncture site after femoral artery puncture can effectively avoid postoperative bleeding. Compression and hemostasis of the puncture site after femoral artery puncture is an effective means to prevent postoperative complications (such as hematoma or pseudoaneurysm, etc.). In order to avoid local bleeding after femoral artery puncture, it is routinely used clinically to compress the puncture site with a sandbag for 6 hours, and then use multiple layers of gauze or bandages to compress and bandage the femoral artery puncture site for 24 hours; the lower limb on the surgical side is kept in a forced straight state for a long time, even for several days.

[0003] In addition, to prevent postoperative complications or bleeding, the lower limb on the surgical side needs to be forced to stay straight for a long time or even for several days. The recovery and healing time after femoral artery puncture is generally 3-7 days. Most patients need to be accompanied by a caregiver, which makes the caregiver tired. Although some patients have strong self-control and can keep their lower limbs straight for a long time when awake, they will inevitably bend their knees in a daze when they are asleep in the middle of the night, which may cause postoperative complications such as local hematoma or bleeding.

[0004] Some patients use fixed braces to fix their lower limbs to prevent them from bending their knees in a confused state; different patients have different ages and great differences in height and body length, but the length of existing fixed braces is relatively uniform, and the length of the fixed braces cannot be adjusted according to the different lengths of the lower limbs of different patients; in addition, existing fixed braces are often straight rods that cannot be bent, and the forced extension of the lower limbs for several days causes problems such as stiffness and pain in the patient's lower limbs; existing fixed braces cannot slightly bend the patient's lower limbs according to the patient's recovery progress to improve the patient's lower limb stiffness and pain and other problems, and the existing fixed braces are not firmly fixed and are not very comfortable to use.

[0005] In addition, if the lower limb on the operated side is forced to be straight for a long time, the blood circulation in the lower limb will be slow, which may easily lead to the formation of lower limb venous thrombosis. If the patient uses a fixed support to keep the lower limb straight, the lower limb on the operated side can be made to perform ankle pump exercise, which can promote blood circulation in the lower limb on the operated side and reduce the probability of thrombosis. Therefore, there is an urgent need for an auxiliary rehabilitation device after femoral artery puncture that can adjust the relative position of the device according to the different lengths of the patient's lower limbs, gradually change the flexion angle of the rehabilitation device according to the patient's rehabilitation progress, and keep the lower limbs straight while prompting the foot to perform ankle pump exercise.
