Preferably, the front surface of the binding belt body is provided with a clamping groove. The draw-in groove can be used to place the card, records patient's dialysis number and name, can avoid obscuring.

Preferably, the alarm is a small horn or a flashing lamp.

Preferably, it also includes a communication module, which may be a wireless communication interface with near-field wireless communication (such as bluetooth or WIFI) for sending an alarm command to a mobile terminal (such as a mobile phone or a dedicated monitor) of a surrounding medical staff, so as to perform real-time monitoring on the wound bleeding condition of the patient.

Preferably, buttons are arranged at two ends of the binding belt body. Further, the button can set up one row or multirow, it is fixed that the bandage body passes through the button, and can adjust the elasticity according to patient's arm, compares in the magic subsides, and the connected mode of button is more firm, is difficult for splitting.

The utility model has the advantages that:

the utility model discloses be provided with micro-device such as humidity transducer, microcontroller, alarm and battery on traditional bandage, can detect the oozing blood condition of patient's bandage the inside wound in real time when using, when sensing inside white gauze cotton ball moist and red liquid appear, can report to the police immediately, both can remind the patient very first time to discover the condition of bleeding, can in time indicate medical personnel to nurse again.

The utility model discloses in, detachable monitoring module that humidity transducer, microcontroller, alarm and battery can be integrated to this repeatedly usable, reduce cost.
