Abstract:
Objective To design a self-aid pressurized heating tourniquet to decrease the mortality and morbidity of post-traumatic hemorrhage of limbs in highland cold regions.Methods The tourniquet was in the form of long strip and consisted of a gas generating heating mechanism,an inflatable cuff,a decompression mechanism and a micro timer.The gas generating heating mechanism was composed of an inner cylinder and an outer cylinder,which were fixed with screws;the inflatable cuff had two variations for the upper limb and lower limb respectively,with fabric for fixing on the outer side and an airbag set on the inner side;the decompression mechanism had a pressurized valve as its main component;the electronic micro timer was secured to the slot on the gas generating heating mechanism by an insertion clasp.Results The tourniquet developed enabled self-aid hemostasis in 1 to 2 s for post-traumatic hemorrhage of limbs in highland cold regions,and could effectively prevent the affected limb from losing temperature.Conclusion The tourniquet developed gains advantages in easy operation,hemostasis,heat preservation and adjustable pressure,which is of significance for enhancing the self-aid ability for post-traumatic hemorrhage of limbs in highland cold regions.[Chinese Medical Equipment Journal,2024,45(3):111-114]
