Abstract
An infusion apparatus for infusing liquid into a patient and having a housing adapted to receive a cassette with a flexible tube through which liquid may be pumped, a pump disposed within the housing and adapted to pump liquid through the flexible tube of the cassette, and a door, connected to the housing, which has an open position and a closed position. The apparatus includes latching means for maintaining the door in the closed position and first and second release means operatively coupled to the latching means. The first and second release means are independently operable so that the door is released by the latching means only upon actuation of both the first and second release means. As a result, inadvertent opening of the door due to jarring of the infusion apparatus is minimized or prevented. The latching means may comprise first and second latching means for maintaining the door in the closed position, wherein the first latching means is releasable only by the first release means and wherein the second latching means is releasable only by the second release means. The first latching means may be a slidable plate disposed in contact with the first release means, and the second latching means may be a second slidable plate disposed in contact with the second release means. The door may have a rod connected thereto, and the slidable plates may have latches connected thereto which engage the rod when the door is in the closed position.
