Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an arm puncture auxiliary device. Background Art

[0002] Radial artery puncture is a procedure between internal medicine and surgery, and is an interventional treatment like femoral artery puncture and carotid artery puncture. Under the guidance of the interventional imaging system DSA, the therapeutic drugs and equipment are directly applied to the lesion site, which has the advantages of safety, minimally invasive, few side effects, low treatment costs, and fast postoperative recovery. However, the diameter of the distal radial artery is relatively small, and the puncture is difficult. The doctor's learning curve for distal radial puncture is long. During the puncture, the patient needs to cooperate with the position and angle of the hand. During the operation, the patient needs to keep the hand position constant for a long time, which often causes abnormal fatigue of the patient's hand muscles and causes the hand position to move or the angle to change.

[0003] For example, a Chinese utility model patent with authorization announcement number CN206641922U discloses a pediatric radial artery puncture and indwelling fixation handstand, which is composed of an intermediate layer, a hard bottom layer, a hand grip sponge, and a wrist pad sponge; the intermediate layer is composed of an intermediate layer body, a hand grip strap, and an arm strap; a hand grip strap is provided on each side of the intermediate layer body near the head end, and the right end of the right hand grip strap is connected to a nylon hook strap; a hand grip strap is provided on each side of the intermediate layer body near the tail end, and the right end of the right arm strap is connected to a nylon hook strap; nylon velvet straps are provided on the hand grip strap, arm strap, and intermediate layer body; the hard bottom layer is provided with ventilation holes; nylon hook straps are provided at the bottom of the hand grip sponge and wrist pad sponge, and the front and rear heights of the wrist pad sponge are different. Its advantages are: specially designed for radial artery puncture and indwelling in children; the hand holder is more stable when puncturing, which helps to improve the accuracy and success rate of puncture operation; the physiological structure of children's hands, wrists and forearms is fully considered during indwelling, and the fixation is safe, which reduces the displacement and folding of the indwelling needle and improves the safety of indwelling.

[0004] When performing distal radial puncture, the patient needs to maintain a fist-clenched posture. Therefore, we propose an arm puncture auxiliary device to solve the above problem. Utility Model Content
