[0002] Coronary intervention via the radial artery is widely used clinically. The radial artery, located superficially between the distal radius and the flexor carpi radialis tendon, is an ideal site for palpation and puncture. During radial artery puncture, the patient's arm is typically supported by a support pad, currently primarily using cushions or pillows. Chinese utility application CN204192918U discloses a post-radial artery intervention positioning pad, comprising a sponge pad body with a 30° slope and an arc-shaped groove penetrating the pad body, the length of which is the same as the length of the slope.
