The invention aims to be realized by the following technical scheme: the utility model provides an automatic fill gassing tourniquet, is including the area body that contains the gasbag and for the inflatable aerating device of the area body, aerating device with connect through the trachea between the area body, still be equipped with pressure sensor in the area body, pressure sensor is through setting up electric wire and the aerating device electric connection in the trachea, aerating device includes the casing, be equipped with display screen, power button on the casing, start/stop the button, step up button, step down the button, be equipped with pressurization air pump, electromagnetism discharge valve and control module in the casing, control module includes singlechip, data acquisition module, keying module and display drive module.
In the scheme, the belt body is sleeved on the limb part of the patient needing hemostasis, and then the inflating device is started to inflate the air bag in the belt body, so that enough pressure is generated between the belt body and the limb of the patient to block the blood flow of the limb of the patient. The workload of medical staff is reduced, and the physical strength is saved. The pressure in the belt body detected by the pressure sensor in the belt body is displayed on the display screen, when the pressure reaches the set pressure, the pressurization air pump stops working, the control module starts delay timing, and after the delay time is up, the electromagnetic exhaust valve discharges the gas in the belt body, so that the limb of a patient is prevented from being necrotic due to forgetting to timely unbind the tourniquet. The pressure in the belt body can be adjusted by the pressure increasing button and the pressure reducing button on the inflating device to adapt to individual difference, the situation that the hemostatic effect of some people is not ideal is avoided, or the limb is uncomfortable due to too tight binding, and the gas pressure in the belt body can be properly reduced on the premise of not influencing the hemostatic effect.
Preferably, the data acquisition module is electrically connected with the pressurization air pump, the electromagnetic exhaust valve and the pressure sensor.
Preferably, the display screen is a liquid crystal display screen.
Preferably, the single chip microcomputer is an MC68HC908LJ12 or AT89S51 chip.
Preferably, the pressure sensor is an MPX5050 piezoresistive pressure sensor or an ASDX001 microstructure pressure sensor.
Preferably, a hair surface of the hook and loop fastener is arranged on one side of the belt body, and a hook surface of the hook and loop fastener is arranged on the other side of the belt body.
Preferably, a rechargeable battery is disposed in the housing.
Compared with the prior art, the utility model discloses following beneficial effect has: the utility model can automatically inflate the belt body to block the blood flow of the limbs of the patient, thereby reducing the workload and physical strength of medical staff; the air is automatically deflated after timing, so that the risk that the limbs are necrotized due to blood flow blockage for too long time is avoided; the pressure in the belt body is adjustable, and the belt is suitable for individual differences of various crowds.
