Point-pressure application system
An apparatus for applying point-pressure to a wound site that helps occlude open blood vessels includes a pressure applicator, a mounting plate, articulating strap attachment points, and counter-pressure cavities. The articulating strap attachment points attach to straps around a patient's body so that the apparatus is stabilized over a patient's wound. Moreover, the counter-pressure cavities permit a user to apply leverage caused by counter-force mechanism (while also applying a downward force on the pressure applicator). These features enable a user to quickly and easily apply point pressure to a wound site.
1. An auto-locking apparatus for controlling hemorrhage, the apparatus enabling a user to apply point pressure extremely rapidly with a single hand, the apparatus comprising:
a mounting plate for mounting the apparatus over a wound site, the mounting plate comprising a top surface and a bottom surface;
an articulating strap attachment point extending from the mounting plate, the articulating strap attachment point connecting to a buckle on a strap that secures the apparatus over the wound site,
the mounting plate and the buckle configured to freely rotate around each other when the mounting plate and the buckle are connected to the articulating strap attachment point, the articulating strap attachment point thus ensuring that the mounting plate remains parallel to the wound site when the apparatus is secured to a patient;
a pressure applicator for applying point pressure to the wound site, the pressure applicator extending through the mounting plate and being stabilized in a lateral direction by the mounting plate;
an auto-locking mechanism enabling the pressure applicator to travel, upon application of downward force, towards the wound site when the apparatus is placed over the wound site, the auto-locking mechanism preventing the pressure applicator from travelling away from the wound site when downward pressure is removed from the pressure applicator, the auto-locking mechanism comprising a locking tab; and
a finger hold disposed on the mounting plate, the finger hold enabling a user to apply counter-force in a generally opposite direction to the downward force that may be applied to the pressure applicator, the counter-force enabling a user to apply leverage when applying downward force to the pressure applicator.
2. The apparatus of claim 1 , wherein the mounting plate is further comprised of an aperture or opening that extends from the top surface of the mounting plate to the bottom surface of the mounting plate.
3. The apparatus of claim 2 , wherein the pressure applicator travels through the aperture or opening in the mounting plate.
4. The apparatus of claim 1 , wherein the pressure applicator is further comprised of a gripper that is disposed on the distal end of the pressure applicator, the gripper comprised of a compressible material.
5. The apparatus of claim 1 , wherein the pressure applicator is further comprised of a hemorrhage stopper that is disposed on the proximal end of the pressure applicator, the hemorrhage stopper stopping hemorrhage at the wound site upon application of force.
6. The apparatus of claim 1 wherein the locking tab of the auto-locking mechanism is further comprised of an aperture or opening.
7. The apparatus of claim 6 , wherein the pressure applicator travels through the aperture or opening in the locking tab.
8. The apparatus of claim 7 , wherein the locking tab extends at an angle at a resting position, the angle enabling the locking tab to apply friction to the pressure applicator and prevent it from moving longitudinally through the locking tab's aperture or opening.
9. The apparatus of claim 8 , wherein the friction applied on the pressure applicator by the locking tab may be removed by applying downward pressure on the locking tab, which places the locking tab on a plane that is orthogonal to the pressure applicator.
10. The apparatus of claim 6 , wherein the locking tab extends from a tab holder, wherein the tab holder is connected to one end of the locking tab.
11. The apparatus of claim 10 , wherein the tab holder extends from the mounting plate, the tab holder designed to hold the locking tab, by default, at an offset angle, which enables the locking tab to apply friction on the pressure applicator.
12. The apparatus of claim 11 , wherein the tab holder is further comprised of vertical headroom, which permits the locking tab to be depressed at an end that is not connected to the tab holder, thereby placing the locking tab in a plane that is substantially orthogonal to the pressure applicator.
13. The apparatus of claim 1 , wherein the finger hold is molded into the mounting plate.
14. The apparatus of claim 1 , wherein the finger hold is comprised of an aperture or opening, wherein the pressure applicator travels through the aperture or opening in the mounting plate and the aperture or opening in the finger hold.
15. The apparatus of claim 1 , wherein the apparatus is comprised of four articulating strap attachment points.
16. The apparatus of claim 15 , wherein each articulating strap attachment point connects to a buckle, each buckle being connected to a strap.
17. The apparatus of claim 16 , wherein the straps connect together around a patient to secure the apparatus over a wound site.
18. The apparatus of claim 17 , wherein, when the straps are secured around the patient, the articulating strap attachment points permit rotation to ensure that the apparatus remains substantially parallel to the surface of the wound site.
