Abstract:
A new adaptive pneumatic tourniquet was developed for limb operation and first-aid. The crucial hardware circuits of the adaptive pneumatic tourniquet were designed based on the microprocessor C8051F340 and blood pressure module CSN602, software was programmed and an experiment was carried out for verifying the system. Results showed that the prototype could measure accurately systolic blood pressure, heart rate and other relative parameters and the designed device could adjust tourniquet cuff's pressure through inflation and deflation according to systolic blood pressure and limb circumference. This designed system integrated the advantages of the adaptive pneumatic tourniquet, and could be used for controlling life-threatening extremity hemorrhage operation and maintaining a bloodless opeation field.
