Side loading ratchet to stop arterial bleeding during combat trauma and the like
Described embodiments provide systems and methods for a tourniquet system compression device. The compression device includes a spooling mechanism, a ratchet release, a safety release, and a profile surface. The spooling mechanism includes a first side loading configured to receive a first tourniquet strap, and a second side loading slot configured to receive a second tourniquet strap. The ratchet release disengages a ratchet gear from a pawl. The safety release prevents the ratchet gear from disengaging with the pawl when the safety release is active. The profile surface generates a pressure profile against a subject. The compression device includes a fixed end of webbing. The compression device is coupled to the webbing. The spooling mechanism is configured to gather the webbing. The compression device includes a preset pressure profile. The compression device includes a fixed end fitting. The compression device is configured for side entry loading of the webbing.
1. A tourniquet system comprising:
a compression device comprising:
a spooling mechanism comprising:
a barrel configured to rotate to twist at least one tourniquet strap at least partially around the barrel, the barrel comprising:
a first side loading slot and a second side loading slot configured to receive a first tourniquet strap; and
a third side loading slot and a fourth side loading slot configured to receive a second tourniquet strap;
a ratchet release to disengage a ratchet gear from a pawl;
a safety release to prevent the ratchet gear from disengaging with the pawl when the safety release is active; and
a profile surface to generate a pressure against a subject.
2. The tourniquet system of claim 1 , wherein the compression device further comprises a fixed end of webbing.
3. The tourniquet system of claim 2 , wherein the spooling mechanism is configured to gather the webbing.
4. The tourniquet system of claim 3 , wherein the compression device includes a preset pressure profile.
5. The tourniquet system of claim 1 , wherein the compression device further comprises a fixed end fitting.
6. The tourniquet system of claim 1 , wherein the compression device is configured for side entry loading of at least one of the first tourniquet strap or the second tourniquet strap, wherein the at least one of the first tourniquet strap of the second tourniquet strap is inserted into the compression device using a side of the first or second tourniquet strap rather than an end of the first or second tourniquet strap.
7. The tourniquet system of claim 1 , wherein the first tourniquet strap and the second tourniquet strap are configured to press into the subject.
8. The tourniquet system of claim 1 , further comprising a button to actuate the ratchet release.
9. The tourniquet system of claim 8 , wherein the button moves the ratchet gear from the pawl.
10. A tourniquet system comprising:
a compression device comprising:
a spooling mechanism having a barrel comprising a first side loading slot and a second side loading slot configured to receive a tourniquet strap;
a ratchet release disengaging a pawl from a ratchet gear;
a safety release to prevent the pawl from disengaging with the ratchet gear when the safety release is active; and
a profile surface to generate a pressure profile against a subject.
11. The tourniquet system of claim 10 , wherein rotation of the barrel pulls a first part of the tourniquet strap in a first direction and pulls a second part of the tourniquet strap in a second direction.
12. The tourniquet system of claim 10 , wherein the tourniquet strap extends across the profile surface from a first end of the profile surface to a second end of the profile surface, and the barrel is disposed between the first end and the second end.
