Abstract
The present disclosure discusses systems and methods for controlling a hemorrhage. The hemorrhage control device can include a harness that is worn around an upper junctional area and a lower junctional area of a user. The hemorrhage control device can also include a compression device that is configured to reversibly couple with the harness. The compression device can include a compression puck and a handle. The handle can be coupled with the harness. When rotated the handle can constrict the harness around the upper junctional area or the lower junctional area. The constriction of the harness can also cause the compression puck to compress the upper junctional area or the lower junctional area.
Core Innovation
The invention relates to a hemorrhage control device designed to apply compressive and constrictive pressure to the upper and lower junctional areas of a user. It includes a harness configured to be worn around these junctional areas and a compression device that reversibly couples with the harness. The compression device consists of a compression puck and a handle. When the handle is rotated, it constricts the harness around the targeted junctional area, causing the compression puck to apply pressure to that area, thereby controlling hemorrhage.
The problem addressed is the need for effective and rapid control of bleeding, particularly at junctional areas where traditional tourniquets are challenging to apply. Conventional tourniquets apply pressure by encircling an extremity, but controlling blood flow at junctional areas is difficult, leading to delays in hemorrhage control. The disclosed device aims to provide a system that can be worn prior to injury and quickly activated to constrict blood flow at these critical junctional areas by simultaneously applying compressive and constrictive pressure.
Claims Coverage
The patent includes one independent claim that defines the core inventive features of the hemorrhage control device.
Harness configured for upper and lower junctional areas
A harness configured to be worn around both an upper junctional area and a lower junctional area of a user.
Compression device with compression puck and handle coupled to harness
A compression device comprising a compression puck and a handle extending from the puck, the device being positionable at the upper and lower junctional areas and configured to detachably couple with the harness.
Compression puck applying pressure to junctional areas
The compression puck is configured to apply pressure to at least one portion of the upper or lower junctional area of the user.
Handle constricting the harness around junctional area
The handle is configured to constrict the harness around the selected junctional area when rotated.
The independent claim covers a hemorrhage control device comprising a harness wearable around upper and lower junctional areas and a detachable compression device with a puck and handle, where the handle constricts the harness and the puck applies pressure to control hemorrhage.
Stated Advantages
The harness can be worn prior to injury, reducing time needed to control bleeding.
The compression device applies simultaneous compressive and constrictive pressure to occlude arteries and veins effectively.
The ratchet mechanism maintains constriction without continuous user input, ensuring sustained pressure.
Modular components such as detachable compression devices and MOLLE loop integration allow versatility and ease of use.
Documented Applications
Use by soldiers as part of everyday combat dress to rapidly control hemorrhage at upper and lower junctional areas during injury.
Application on upper junctional areas, including axillary and subclavian arteries, to control arterial bleeding.
Application on lower junctional areas, including femoral, iliac, and aortic arteries, for hemorrhage control.
