Specific embodiment

Specific embodiment of the present utility model is further illustrated with reference to the accompanying drawing:

A kind of hospital bed alarm system, in which: including proximity sensor 1, controller 2, call for help switch 3, wireless telecommunications mould Block 4, gsm module 5, combined aural and visual alarm 6, infusion test module 7, bed-wetting detection module 8 and temperature check module 9, described connects Nearly sensor 1 and calling for help switch 3 are all connect with controller 2, and the proximity sensor 1 is mounted in bed body, and described is wireless Communication module 4 and gsm module 5 are all connected with controller 2, and the combined aural and visual alarm 6 is mounted on the head of a bed and combined aural and visual alarm 6 It is connect with controller 2, the infusion test module 7, bed-wetting detection module 8 and temperature check module 9 all connect with controller 2 It connects, is equipped in the controller 2 in single-chip microcontroller and controller 2 and embedded OS is installed.

In embodiment, HX711 analog-to-digital conversion module and 4 piezoresistive composition full-bridges are installed in infusion test module 7 Formula detection circuit.Infusion test detects the pressure of transfusion suspender using high-precision weighing sensor.Sensor probe upper and lower surface Respectively there is a foil gauge, there are 2 piezoresistives in each foil gauge.4 piezoresistives form a full-bridge type detection circuit.? When electric bridge imbalance, export analog voltage signal and give HX711 analog-to-digital conversion module, HX711 module by the digital quantity after conversion with The mode of serial communication exports.Detection threshold value is first set, the pressure that detection infusion bottle applies transfusion suspender judges feelings of being infused Condition issues alarm signal when medicine bottle weight is less than given threshold, and caregiver is notified to stop infusion or dressing.
