Abstract

A blood pressure cuff having a pair of flexible gas-impermeable sheets wherein each of the sheets has an inner and an outer side and wherein the inner sides are placed in contact and the edges of the sheets are fused along a periphery thereof to form an interior chamber. At least one hook fastener portion is disposed on one outer side of one of the sheets and at least one loop portion is disposed on an outer side of the other of the sheets. A conduit means is attached to one of the flexible sheets for connecting to a source of pressurized fluid for allowing inflation and deflation of the interior chamber. The sheets are fused together by RF welding along a perimeter of one outer side of one of the sheets. The hook fastener portion, the loop portion, and the conduit means are each RF welded to an outer side of one of said sheets.

Claims

1. An inflatable blood pressure cuff comprising:

a pair of flexible gas-impermeable sheets, each of said sheets having an inner and an outer side, wherein said inner sides are placed in contact and the edges of said sheets are fused along a periphery thereof to form an interior chamber;

at least one hook fastener portion disposed on one outer side of one of said sheets and at least one loop portion disposed on an outer side of the other of said sheets; and

conduit means attached to one of said flexible sheets for connecting to a source of pressurized fluid for allowing inflation and deflation of said interior chamber, wherein said sheets are fused together by RF welding along a perimeter of one outer side of one of said sheets,

and further wherein said at least one hook fastener portion, said at least one loop portion, and said conduit means are each RF welded to an outer side of one of said sheets.

2. The inflatable blood pressure cuff according to claim 1, wherein said flexible sheets comprise a fabric material.

3. The inflatable blood pressure cuff according to claim 2, wherein said fabric material is nylon.

4. The inflatable blood pressure cuff according to claim 2, wherein said fabric material has a coating, said coating comprising urethane.

5. The inflatable blood pressure cuff according to claim 4, wherein the outer side of each of said flexible sheets includes a urethane coating, said coating of the outer side having a thickness less than 0.001 inches.

6. The inflatable blood pressure cuff according to claim 5, wherein said coating further comprises an antimicrobial agent.

7. The inflatable blood pressure cuff according to claim 1, wherein said conduit means includes a port fitting attached to an outer side of one of said opposed sheets, wherein said port fitting is RF welded to the inner side of the flexible sheet.

8. The inflatable blood pressure cuff according to claim 1, including a cleat portion disposed on one outer side of one of said sheets.

9. The inflatable blood pressure cuff according to claim 1, including a cleat portion, wherein said cleat portion is RF welded to an outer side of one of said flexible sheets.

10. The inflatable blood pressure cuff according to claim 1, including a plurality of range markings disposed on one outer side of one of said sheets.
