John M. Croushorn has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10751067
    Abstract: A self-stabilizing pneumatic abdominal aortic tourniquet that utilizes a semi-ridge retaining strap, a ratcheting retaining buckle, and an elastic guide cord on the lower penetrating end of a wedge-shaped bladder. A rigid baseplate is supported by a waist belt having a width identical with the waist belt so that the baseplate provides a stable base for positioning the bladder over a selected area of the patient's abdomen. The air bladder is affixed to the underside of the baseplate, which is initially kept in a deflated condition collapsed against the baseplate, and includes an elastic cord, such as a shock cord, configured to bias the tip of the wedge or “V” shaped bladder in the middle of the baseplate. An air source connected to the air bladder causes inflation and penetration of the lower edge of the bladder into the patient's abdomen thereby causing aorta occlusion.

  • Patent number: 10555741
    Abstract: A device to increase intra-pelvic compartment pressure for the controlling of internal hemorrhages is presented. The device controls internal hemorrhaging by supplementing the occlusion effectiveness of a pneumatic tourniquet with a shaped device that increases the overall internal pressure in a human compartment, such as the inguinal area, to assist in the cessation of bleeding in that region. One side of the device includes a flat base that is adapted to be placed against a patient at the targeted body site. The other side has a generally corrugated shape that is sized to receive an inflatable, wedge-shaped bladder from the pneumatic tourniquet. The overall shape of the invention includes a tapered end that corresponds with the inferior angle of the pubic rami and pelvic area generally so that when pressed against the patient by the pneumatic tourniquet bladder a uniform distribution of pressure occurs over the inguinal area.

  • Patent number: 10555740
    Abstract: A device to increase intra-abdominal compartment pressure for the controlling of internal hemorrhages is presented. The device controls internal hemorrhaging by supplementing the occlusion effectiveness of a pneumatic tourniquet with a shaped device that increases the overall internal pressure in a human compartment, such as the upper abdomen, to assist in the cessation of bleeding in that region. One side of the device includes a flat base that is adapted to be placed against a patient at the targeted body site. The other side has a generally corrugated shape that is sized to receive an inflatable, wedge-shaped bladder from the pneumatic tourniquet. The overall shape of the invention includes a tapered upper end that corresponds with the inferior angle of the lower ribs in a human torso so that when pressed against the patient by the pneumatic tourniquet bladder a uniform distribution of pressure occurs over the upper abdomen region.

  • Patent number: 9149280
    Abstract: A portable pneumatic abdominal aortic tourniquet for occlusion of the abdominal descending aorta to restrict blood supply to a non-compressible arterial hemorrhage in or below the inguinal region is presented. The tourniquet includes an adjustable waist strap for securing it around the abdomen of a patient and a windlass rod connected to the waist strap to selectively tighten the strap as needed to tightly secure it to patient. A directed air bladder is mounted to the waist strap having a generally “V” shaped construction and is expanded for exerting directed pressure against the abdomen. Upon inflation of the air bladder and adjustment of the windlass, occlusion or restriction of blood flow through the abdominal descending aorta will occur which will achieve cessation of hemorrhage in or below the inguinal area or achieve other therapeutic effects like elevated blood pressure to enhance CPR or blood flow control to the lower extremities.

  • Publication number: 20130310872
    Abstract: A portable pneumatic abdominal aortic tourniquet for occlusion of the abdominal descending aorta to restrict blood supply to a non-compressible arterial hemorrhage in the abdominal region. The tourniquet comprising an adjustable waist strap for securing around an abdomen; a directed air bladder mounted to the waist strap having a generally “V” shaped construction operable between a deflated condition wherein the directed air bladder is collapsed, and an inflated condition wherein the directed air bladder is expanded for exerting pressure against the abdomen; and, an air source connected to the directed air bladder for operating the directed air bladder between the deflated condition and the inflated condition.
