Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a hand lifting fixer. Background Art
[0002] In clinical practice, coronary angiography is a common and effective method for diagnosing coronary heart disease. By injecting contrast agents, the coronary arteries are visualized, thereby clarifying the location, range, and degree of the lesions. After surgery, the patient's upper limbs need to be raised to observe the puncture site of the patient's limbs, which is also conducive to blood return and promotes recovery. At present, many hospitals do not have special tools for raising the patient's limbs. In clinical practice, pillows are often used to raise the upper limbs, but the height of the pillows cannot be adjusted to meet different height requirements.
[0003] Patent No. CN214909608U discloses a post-coronary angiography upper limb raising device, comprising a hand-holding slot, which is a U-shaped structure with a concave surface facing upward, one side of which is fixedly connected to the upper surface of the second support rod, and the other side of which is symmetrically provided with a pair of fixing belts, and the patient puts the upper limb into the hand-holding slot, and then adjusts the height and angle of the hand-holding slot. As is known to all, the upper limb is divided into the forearm and the upper arm. If the forearm is put into the hand-holding slot, the upper limb will slide down. If the upper arm is put into the hand-holding slot, in order to maintain the oblique upward angle of the forearm, the patient needs to support the forearm with all his strength, which cannot last long.
