Surgical tourniquet cuff system
First Claim
1. A tourniquet cuff apparatus comprising:
- a cuff having an inflatable portion having a length sufficient to encircle a limb of a patient at a desired location;
a cuff port communicating pneumatically with the inflatable portion;
a cuff connector communicating pneumatically with the cuff port and adapted for releasably connecting to a tourniquet instrument connector to establish a pneumatic passageway between the cuff connector and the instrument connector; and
a cuff sheath forming a flexible conduit sized to allow an operator to connect the cuff connector to the tourniquet instrument connector within the sheath conduit.

Abstract
A surgical tourniquet cuff system includes a tourniquet cuff with a cuff connector for communicating pneumatically with the cuff and for releasably connecting to a tourniquet instrument connector to establish a pneumatic passageway between the cuff connector and the tourniquet instrument connector. A tourniquet instrument supplies pressurized gas through the pneumatic passageway to the cuff. The tourniquet instrument connector includes a cuff pressure transducer for producing a cuff pressure signal indicative of the pressure of gas within the gas passageway near the connection. The cuff may include a cuff usage register for containing a cuff usage record and the tourniquet instrument connector may include a cuff usage register interface for reading the record. The tourniquet cuff may further include a cuff sheath forming a flexible conduit containing the cuff connector and sized to allow the connection of the cuff connector to the tourniquet instrument connector within the sheath.

10. A surgical tourniquet cuff system, comprising:
-
a tourniquet cuff having an inflatable portion of sufficient length to encircle a limb at a desired location, wherein the cuff includes cuff connector communicating pneumatically with the inflatable portion and adapted for releasably connecting to a tourniquet instrument connector to establish a pneumatic passageway between the cuff connector and the tourniquet instrument connector;
tourniquet instrument including the tourniquet instrument connector and further including tourniquet instrument tubing forming a flexible pneumatic conduit attached to the tourniquet instrument connector, wherein the tourniquet instrument supplies pressurized gas through the pneumatic passageway established by the connection of the tourniquet instrument connector to the cuff connector to the inflatable portion of the cuff, and wherein the tourniquet instrument connector includes a cuff pressure transducer for producing a cuff pressure signal indicative of the pressure of gas within the gas passageway near the connection. - View Dependent Claims (11, 12, 13, 14)

- 15. A sterile sheath adapted for containing a cuff connector of a tourniquet cuff, the cuff connector communicating pneumatically with an inflatable portion of the cuff, wherein the sheath containing the cuff connector is formed of a flexible material that is impervious to micro-organisms, and wherein the sheath containing the cuff connector further forms a barrier to micro-organisms surrounding the port at a port location between the connector and the inflatable portion of the cuff.
-
17. The apparatus as described in 16, wherein the cuff is formed of materials having physical properties that are substantially unchanged by sterilization with autoclaving.
