Abstract
A pump cassette is configured for coupling with a pump device. The pump cassette may include a fluid lumen adapted for passage and propulsion of an infusion fluid toward a patient; a valve assembly that can be actuated to regulate fluid flow through the fluid lumen; and a frame coupled to the fluid lumen and the valve assembly. The frame is adapted to be inserted into a seat of a pump device. The frame is configured to be inserted into the seat only when aligned in a predetermined orientation relative to the seat.
Claims32
A pump cassette for coupling with a pump device, the pump cassette comprising:
- a fluid lumen adapted for passage and propulsion of an infusion fluid toward a patient;
- a valve assembly that can be actuated to regulate fluid flow through the fluid lumen;
- and
- a frame coupled to the fluid lumen and the valve assembly, the frame adapted to be inserted into a seat of a pump device, the frame configured to be inserted into the seat only when aligned in a predetermined orientation relative to the seat.
A pump cassette as in claim 20, wherein the connector is bonded to the fluid lumen.
A pump device, comprising:
- a pumping mechanism;
- a housing defining a seat configured to receive a pump cassette having a fluid lumen that can be acted upon by the pumping mechanism so as to pump fluid through the fluid lumen of the pump cassette, wherein the valve assembly transitions between a flow state that permits fluid flow through the fluid lumen and a non-flow state that blocks fluid flow through the fluid lumen, the seat shaped to receive a pump cassette only when the pump cassette is aligned in a predetermined orientation relative to the seat;
- a door attached to the housing and configured to be transitioned between an open position wherein the seat is exposed for receipt of a pump cassette and a closed position wherein the door secures a pump cassette within the seat;
- a door actuator configured to transition to a locked state that locks the door in the closed position, wherein the door actuator is configured to automatically transition the valve assembly to the open state when the door actuator is transitioned to the locked state.
A method for coupling a pump cassette with an infusion pump, the method comprising:
- aligning a pump cassette in a predetermined orientation relative to the infusion pump, wherein the pump cassette can only be coupled to the infusion pump when the pump cassette is aligned in the predetermined orientation relative to the infusion pump;
- inserting at least a portion of the pump cassette into the infusion pump.
