User-Friendly Junctional Tourniquet Device

A tourniquet device for restricting flow of blood in a junctional location of a patient, said tourniquet device comprising:

• a strap for wrapping around the body of a patient proximate to said junctional location, said strap having a first end and a second end, said first end being fixed to a buckle end and said second end being fixed to a spool, said spool configured for winding and unwinding said strap by rotating about its longitudinal axis;
• a base plate having a patient side and a user side for coupling said first end to said second end to form a loop around the body of a patient, said base plate configured for attachment of said buckle end and said spool;
• at least one ratchet gear and ratchet pawl configured in a resting state to be engaged to prevent said strap from unwinding from said spool;
• at least one pawl release lever configured to disengage said at least one ratchet gear and ratchet pawl to allow said strap to unwind from said spool;
• a collar pivotably and translatably attached to said base plate to mechanically engage with a threaded shaft, said threaded shaft configured to mechanically engage with a pressure pad to apply pressure to a patient as said threaded shaft is rotated about its longitudinal axis, said pressure pad being rotationally and releasably mounted to said patient side of said base plate;
• a load transfer element configured to engage and translate with said threaded shaft relative to said base plate;
• a spring element acting between said base plate and said load transfer element and configured to control translation of said threaded shaft relative to said base plate in response to pressure being applied to a patient;
• and
• a user feedback mechanism movably coupled to said load transfer mechanism and configured to provide a real-time indication to a user of pressure applied to a patient.
