Abstract

A blood pressure cuff is defined by a first sheet, having an opening, and a second sheet. The second sheet is attached to a bottom of the first sheet to form an interior inflatable portion between the first sheet and the second sheet, with the opening of the first sheet fluidly interconnecting the interior inflatable portion with an exterior of the cuff. The blood pressure cuff is made from a single type of material and can be recycled, biodegradable, or composted.

Claims

1. A blood pressure cuff, the cuff comprising:

a first sheet having an opening;

a second sheet, wherein the second sheet is attached to a bottom of the first sheet;

an interior-inflatable portion formed between the bottom of the first sheet and a top of the second sheet, wherein the opening of the first sheet fluidly interconnects the interior-inflatable portion with an exterior of the cuff, the first and second sheets being made from a fluid impermeable material;

a socket attached to said cuff through said opening and having a circumferential lip that directly and releasably engages one of a hose adapter and a gage housing, said socket fluidly interconnecting the exterior of said cuff with said interior-inflatable portion;

a slotted portion formed in a longitudinally extending section of said first sheet spaced apart from the interior-inflatable portion; and

fastener material disposed on the cuff proximate an end of the longitudinally extending section wherein the cuff is configured to wrap around a limb of a patient during blood pressure measurement such that the fastener material adheres to a top surface of the first sheet and the slotted portion receives the socket and wherein the length of slotted portion and positioning of the socket on the cuff are selected to limit the circumference of the cuff in the configuration during blood pressure measurement when the socket is received in the portion.

2. A cuff as recited in claim 1, wherein the cuff further comprises means for indicating that the cuff has already been used.

3. A cuff as recited in claim 2, wherein means for indicating that the cuff has already been used includes alteration of a color of a treated portion of the cuff after exposure to light.

4. A cuff as recited in claim 1, wherein the fastener material is a hook, made from the fluid impermeable material, attached to a bottom of the first sheet and spaced apart from the second sheet.

5. A cuff as recited in claim 4, wherein the hook is attached to an end portion of the first sheet and on a side of the first sheet including the slotted portion.

6. A cuff as recited in claim 4, wherein a top of the first sheet further comprises a loop fastener configured to engage the hook.

7. A cuff as recited in claim 6, wherein the top of the first sheet comprises a non-woven fibrous material.

8. A cuff as recited in claim 6, wherein the non-woven fibrous material has a weight of about 0.5 to 3.0 ounces per square yard.

9. A cuff as recited in claim 6, wherein a film is laminated to the bottom of the first sheet.

10. A cuff as recited in claim 9, wherein the film has a thickness of about 0.002 to 0.008 inches and a weight of about 1.0 to 7.0 ounces per square yard.

11. A cuff as recited in claim 9, wherein the first sheet has a creep elongation of less than about 0.0065 inches.

12. A cuff as recited in claim 6, wherein the bottom of the first sheet has a smooth texture.

13. A cuff as recited in claim 6, wherein the loop fasteners are degraded upon attachment and subsequent removal from the hook.

14. A cuff as recited in claim 1, wherein the top of the second sheet comprises a non-woven fibrous material configured to resist engagement of the fastener material.

15. A cuff as recited in claim 1, wherein the fluid impermeable material is a recyclable material selected from the group consisting of polypropylene, polyester, polyvinylchloride, and polyethylene.

16. A cuff as recited in claim 1, wherein a length of the first sheet is sized to allow the cuff to be wrapped around a limb at least two times.

17. A cuff as recited in claim 1, wherein the fastener material engages with a portion of the first sheet apart from the inflatable portion of the first sheet.

18. A cuff as recited in claim 1, wherein the cuff is entirely made from the same material.

19. A cuff as recited in claim 1, wherein the longitudinally extending portion is sized to fully overlap the inflatable portion when wrapped.

20. A blood pressure cuff comprising:

a first sheet and a second sheet, each of said first and second sheets having a first side and a second side;

an inflatable compartment defined over a portion of said cuff, said inflatable chamber being defined between the second side of said first sheet and the first side of said second sheet, said inflatable compartment being sized to be wrapped circumferentially about the limb of a patient;

a cylindrical portion extending outwardly from said cuff having an opening that fluidly interconnects with the interior of said inflatable compartment;

wherein at least one of said first and second sheets extends axially from said inflatable compartment defining a longitudinally extending section;

fastener material disposed on the cuff proximate an end of the longitudinally extending section and

a slotted portion formed in said at least one extending section and spaced apart from the inflatable compartment, wherein the cuff is configured to wrap around a limb of a patient during blood pressure measurement such that the fastener material adheres to a top surface of one of the first and second sheets and the slotted portion receives the cylindrical portion and wherein the length of the slotted portion and positioning of the cylindrical portion on the cuff are selected to limit the circumference of the cuff in the configuration during blood pressure measurement when the cylindrical portion is received in the slotted portion.

21. A cuff as recited in claim 20, wherein said slotted portion and said cylindrical portion are centrally aligned relative to a width dimension of said cuff.

22. A cuff as recited in claim 20, wherein said longitudinally extending section includes a hook fastener portion at an extending end thereof and in which said the opposite side of said first sheet includes the fastener material that enables adhesion to said hook fastener portion.

23. A cuff as recited in claim 22, wherein said material of said first sheet is configured to degrade based on detachment of said hook fastener portion from the fastener material, such that said cuff is incapable of being secured after a finite number of uses.

24. A cuff as recited in claim 20, wherein the first sheet comprises a non-woven fibrous material.

25. A cuff as recited in claim 20, wherein said first sheet has a creep elongation of less than about 0.0065 inches.

26. A cuff as recited in claim 20, wherein the entire cuff is commonly made from the same material.

27. A cuff as recited in claim 20, wherein the longitudinally extending portion is sized to fully overlap the inflatable compartment when wrapped.
