The metal plate 8 is locked inside the locking mechanism 10, and then the second fixing unit 2 is fixed on the bedside or bedside of the patient with a special wrench. Pay attention to the installation position of the second fixing unit 2 to ensure that the patient's hand cannot Touching the cannula on his body, when unlocking, press the control button 34, and then scan the QR code or barcode equipped by the medical staff with the camera 14, and the camera 14 converts the scanned QR code or barcode into a The electrical signal is uploaded to the controller 23. After the controller 23 analyzes and processes the received electrical signal, the motor 25 is controlled to drive the elliptical locking piece 26 to leave the locking hole 27. At this time, the locking piece 28 has elastic expansion and contraction performance. The elastic metal plate 8 can be twitched to realize unlocking, and at the same time, the elasticity of the elastic metal plate 8 can be adjusted, and the first fixing unit can be removed from the patient's wrist.
