Recyclable or biodegradable blood pressure cuff

1. A blood pressure cuff comprising:

a first sheet and a second sheet of a fluid impermeable material, said first sheet being longer than the second sheet;

an inflatable portion made up of the first and second sheets, which are sealed to one another at respective edges, wherein the inflatable portion is defined over a portion of the overall length of the cuff and sized to be wrapped circumferentially about the limb of a patient, wherein the inflatable portion includes an opening in the first sheet that permits the passage of a cylindrical socket that is mounted in fluid sealing relation to the first sheet and fluidly interconnects with an interior of the inflatable portion defined by the first and second sheets, the cylindrical socket extending outwardly and substantially perpendicularly from an outer surface of the inflatable portion within a plane defined by a length and width dimension of the cuff; and

a non-inflatable portion made from a portion of the first sheet extending from the inflatable portion having opposed surfaces and a slotted portion extending through the entire thickness of the non-inflatable portion, in which the inflatable portion is sized to be wrapped about the limb of a patient and the non-inflatable portion is sized to overlap the inflatable portion with the cylindrical socket of the inflatable portion extending through the slotted portion of the non-inflatable portion when the cuff is wrapped, wherein the fit between the cylindrical socket and the slotted portion limits the range of limb circumferences to which the cuff can be wrapped.

2. The cuff as recited in claim 1 , wherein the slotted portion and the cylindrical socket are centrally aligned relative to the width dimension of said cuff.

3. The cuff as recited in claim 1 , wherein the entire cuff, including the cylindrical socket, is commonly made from the same material.

4. The cuff as recited in claim 1 , wherein the entire cuff, including the cylindrical socket, is made from recyclable materials having the same recycle code.

5. The cuff as recited in claim 1 , wherein the slotted portion is defined by a major dimension that is parallel to the length dimension of the cuff and a minor dimension that is parallel to the width dimension of the cuff.

6. The cuff as recited in claim 5 , in which the minor dimension of the slotted portion is sized to receive the cylindrical portion and in which the major dimension and the cylindrical socket combine to define a limit of cuff circumferences to which the cuff can be attached.

7. The cuff as recited in claim 1 , wherein length of the slotted portion is significantly larger than the largest diameter of the cylindrical socket in order to enable a range of limb circumferences to which the cuff can be wrapped.

8. The cuff as recited in claim 3 , wherein the cuff is made entirely of polypropylene.

9. The cuff as recited in claim 1 , in which pneumatic means are attached to the cylindrical socket, the pneumatic means extending to a measuring apparatus.

10. The cuff as recited in claim 1 , further comprising at least one indicator that enables a patient or caregiver to recognize that the cuff has already been used.

11. The cuff as recited in claim 10 , wherein the at least one indicator comprises a removable tab covering at least one of an opening in the cylindrical socket or the slotted portion, wherein the removable tab must be removed prior to use of the cuff.

12. The cuff as recited in claim 10 , wherein the at least one indicator comprises an ink packet configured to break and discolor the cuff after use.

13. The cuff as recited in claim 10 , wherein the at least one indicator comprises a folded portion of the cuff sealingly attached to another portion of the cuff, wherein the folded portion must be released prior to use.
