Abstract

Bleeding from blood vessels located in difficult-to-compress regions of the body (especially the abdomen, pelvic or groin region) is controlled by the use of a portable, small-footprint belt-like device that contains multiple inflatable bladders. The inflatable bladders are selectively positioned and inflated over exsanguinating blood vessels, thereby exerting pressure to stop the bleeding. The device may also be used to provide perfusion support in low flow disease states such as hemorrhagic shock and cardiac arrest.

Claims (37)

1. A medical compress device comprising:

a support member circumferentially securable to any area of a body of a patient, said support member having at least two ends separated by a length dimension;

one or more inflatable bladders attached to said support member, said inflatable bladders being selectively inflatable and deflatable, each of said one or more inflatable bladders being positionable at multiple locations from one of said at least two ends to the other of said at least two ends along said length of said support member,

whereby when said at least two ends of said support member are joined together to attach said support member to said patient and said one or more inflatable bladders are positioned at one or more selected locations of said multiple locations along said length of said support member and are inflated, a compressive force is exerted on at least one specific area on said patient and said one or more inflatable bladders remain adjustable along the length dimension during exertion of the compression force and after said support member is attached to said patient; and

at least one tightening member associated with at least a portion of said support member for tightening said support member on said patient after said at least two ends of said support member are joined together,

wherein said support member is comprised of one or more belts,

wherein said support member includes a channel formed in said one or more belts which extends from one of said at least two ends to the other of said at two ends along said length of said support member, and wherein said one or more inflatable bladders includes an attachment knob which includes a portion which fits within said channel.

2. The medical compress device of claim 1 wherein said one or more bladders have length and width dimensions which are different from each other, and wherein said one or more bladders are rotatable about said attachment knob relative to said one or more belts.

3. The medical compress device of claim 1 , wherein said channel forms a grid.

4. A medical compress device, comprising:

a support member circumferentially securable to any area of a body of a patient, said support member having at least two ends separated by a length dimension;

one or more inflatable bladders attached to said support member, said inflatable bladders being selectively inflatable and deflatable, each of said one or more inflatable bladders being positionable at multiple locations from one of said at least two ends to the other of said at least two ends along said length of said support member,

whereby when said at least two ends of said support member are joined together to attach said support member to said patient and said one or more inflatable bladders are positioned at one or more selected locations of said multiple locations along said length of said support member and are inflated, a compressive force that directs pressure into into a groin or pelvic cavity is exerted on at least one specific area on said patient and said one or more inflatable bladders remain adjustable along the length dimension during exertion of the compression force and after said support member is attached to said patient; and

at least one tightening member associated with at least a portion of said support member for tightening said support member on said patient after said at least two ends of said support member are joined together; and

wherein the compressive force compresses blood vessels in the at least one specific area on said patient to reduce uncontrolled bleeding,

wherein said support member is comprised of one or more belts, and

wherein said support member includes a channel forming member attached to said one or more belts which extends from one of said at least two ends to the other of said at two ends along said length of said support member, and wherein said one or more inflatable bladders includes an attachment knob which includes a portion which fits within said channel forming member.

5. The medical compress device of claim 4 wherein said one or more bladders have length and width dimensions which are different from each other, and wherein said one or more bladders are rotatable about said attachment knob relative to said one or more belts.

6. The medical compress device of claim 4 , wherein said channel forming member forms a grid.

7. A method for exerting a compressive force at least one specific area on a patient in need thereof, comprising the steps of

i) circumferentially attaching to any area of a body of said patient a medical compress device, comprising:

a support member, said support member having at least two ends separated by a length dimension;

one or more inflatable bladders attached to said support member, said inflatable bladders being selectively inflatable and deflatable, each of said one or more inflatable bladders being positionable at multiple locations from one of said at least two ends to the other of said at least two ends along said length of said support member; and

at least one tightening member associated with at least a portion of said support member;

wherein said step of attaching includes a step of joining together said at least two ends of said support member;

ii) positioning said one or more inflatable bladders at one or more selected locations of said multiple locations along said length of said support member, wherein said one or more selected locations at least partially covers said at least one specific area on said patient;

iii) inflating said one or more inflatable bladders at one or more selected locations, whereby said step of inflating causes a compressive force to be exerted at said at least one specific area on said patient, said compressive force maintaining a pressure of at least 180 mmHg, and wherein the at least one tightening member is adjustable during application of the compressive force; and

iv) adjusting said at least one tightening member for tightening said support member on said patient after said two ends of said support member are joined together,

wherein said method is used to control hemorrhage.

8. The method of claim 7 , wherein said method is used as an adjunct to cardiopulmonary resuscitation (CPR).

9. The method of claim 7 , wherein at least one of said one or more inflatable bladders is automatically inflated or deflated based on vital signs for said patient, said vital sign being one of heart rate and pulse.

10. The method of claim 7 , wherein the method is used to simultaneously provide compression to control bleeding within a pelvic cavity and to stabilize a fractured pelvis.

11. A medical compress device, comprising:

a support member circumferentially securable to any area of a body of a patient, said support member having at least two ends separated by a length dimension;

one or more inflatable bladders attached to said support member, said one or more inflatable bladders being selectively inflatable and deflatable, each of said one or more inflatable

bladders being positionable at multiple locations along a channel which extends from one of said at least two ends to the other of said at two ends along said length of said support member, wherein said one or more inflatable bladders includes an attachment knob which includes a portion which fits within said channel,

whereby when said at least two ends of said support member are joined together to attach said support member to said patient and said one or more inflatable bladders are positioned at one or more selected locations of said multiple locations along said length of said support member and are inflated, a compressive force is exerted on said patient at least one specific area on said patient and said one or more inflatable bladders remain adjustable along the length dimension during exertion of the compression force and after said support member is attached to said patient.
