Patent ID: 7441714

Claim:
A liquid warming system comprising: a removable basin having a bottom, a set of at least one side wall connected to the bottom of the removable basin so that the set of at least one side wall forms a walled perimeter around the bottom of the removable basin to form a container suitable for holding a fluid, and having an exterior of the removable basin, the basin including a rim; a liquid warming device comprising: a cavity in a top surface of the liquid warming device, the cavity having a bottom, the cavity adapted to receive a portion of the removable basin; a heater adapted to provide heat via a heated surface to at least a portion of the exterior of the removable basin; and a surgical drape for covering at least a portion of the top surface of the liquid warming device, the surgical drape having an opening of sufficient size so that at least a portion of the removable basin can be inserted through the opening in the surgical drape towards the cavity such that a removable basin inserted through the opening in the surgical drape and inserted into the cavity has a least a portion of the exterior of the removable basin adjacent to the heated surface so that thermal energy can pass from the heated surface to at least the portion of the exterior of the removable basin without passing through the surgical drape; the opening of the surgical drape being smaller than an outer perimeter of the basin rim so that the combination of the basin rim and drape form a sterile barrier.
