Abstract
Official abstract text for this publication.
Systems and methods are provided for a valve shut-off system of a medical device. In one embodiment, the valve shut-off system of the medical device includes a first pin movable between a first position where a valve is opened and a second position where the valve is closed, the first pin including a slot, and a second pin having a mating geometry with the slot of the first pin, the second pin adjustable between a locked position that holds the first pin in the first position and an unlocked position that enables movement of the first pin between the first position and the second position.
First claim
Opening claim text (preview).
I claim: 1. A valve shut-off system for a medical device, comprising: a first pin movable between a first position where a valve is opened and a second position where the valve is closed, the first pin including a slot; and a second pin having a mating geometry with the slot of the first pin, the second pin adjustable between a locked position that holds the first pin in the first position and an unlocked position that enables movement of the first pin between the first position and the second position. 2. The valve shut-off system of claim 1 , further comprising an actuator mechanically coupled to the second pin, wherein the actuator adjusts the second pin between the locked position and the unlocked position. 3. The valve shut-off system of claim 2 , wherein the actuator includes a float positioned within a reservoir of the medical device, and wherein the actuator adjusts the second pin from the locked position to the unlocked position responsive to the float reaching a threshold level within the reservoir. 4. The valve shut-off system of claim 2 , wherein the actuator includes a mechanical timer, and wherein the actuator adjusts the second pin from the locked position to the unlocked position responsive to the mechanical timer elapsing. 5. The valve shut-off system of claim 2 , wherein the actuator includes a solenoid, and wherein the actuator adjusts the second pin from the locked position to the unlocked position responsive to a change in an energization state of the solenoid. 6. The valve shut-off system of claim 5 , wherein the change in the energization state of the solenoid is responsive to one of a set timer elapsing and a medical agent level in a reservoir reaching a threshold level. 7. The valve shut-off system of claim 1 , wherein the slot of the first pin includes a locking geometry that engages with the second pin only when the second pin is in the locked position and a sliding geometry that engages with the second pin only when the second pin is in the unlocked position. 8. The valve shut-off system of claim 1 , wherein the first pin and the second pin are positioned in a fill assembly of a reservoir of the medical device, and the valve is positioned in a neck of a refill bottle.
