Anti-falling alarm device for arteriovenous puncture needle for hemodialysis

Abstract

The invention provides an anti-falling alarm device for an arteriovenous puncture needle for hemodialysis. The anti-falling alarm device comprises a fixing plate; the moving device is arranged at the top of the fixed plate and comprises a connecting plate, a moving groove, a servo motor and a reciprocating screw rod; the hemostasis device is in threaded engagement with the surface of the moving device. According to the anti-falling alarm device for the arteriovenous puncture needle for hemodialysis, the alarm gives an alarm, the servo motor is started through the signal receiving controller, the output shaft of the servo motor rotates and is in threaded engagement with the hemostasis device to move downwards, so that the hemostasis cotton cloth is attached to the surface of the arm of a patient, and the bleeding position is pressed for hemostasis; the device is simple in structure and high in practicability, when a puncture needle falling alarm is given out, the hemostasis device can descend, the hemostasis cotton cloth is pressed on the bleeding surface of a patient, hemostasis is conducted on the wound of the patient, the bleeding amount of the patient is reduced, serious blood loss accidents are avoided, and the practicability of the device is improved.
