Abstract:
Provided is a hemodialysis needle with a swing brake pad, comprising an indwelling catheter assembly (1) and a puncture needle tube assembly (2). The indwelling catheter assembly (1) comprises a hose (1.1), a catheter base (1.2), an elastic short tube (1.3), a connecting base (1.4), a swing brake pad (1.5), and a sealing plug (1.6). One end of the hose (1.1) is conical, and the other end of the hose (1.1) is connected to one end of the catheter base (1.2); both ends of the elastic short tube (1.3) are in a sealed connection with the catheter base (1.2) and the connecting base (1.4), respectively, and the elastic short tube (1.3) is located in an inner cavity of the catheter base (1.2) and the connecting base (1.4); one end of the connecting base (1.4) is connected to the catheter base (1.2), and the sealing plug (1.6) is arranged at the other end of the connecting base (1.4); the swing brake pad (1.5) is hinged to an outer surface of the connecting base (1.4), and the swing brake pad (1.5) can swing front and back in an axis direction of the connecting base (1.4).
