Abstract:
1. A drug delivery and monitoring system for a ventilator, comprising: a delivery unit; a gas conduit held by the delivery unit that is attached to ventilator tubing of a ventilator tubing circuit of the ventilator; a plurality of metered dose inhaler (“MDI”) canisters that are concurrently attached to the delivery unit and are configured to selectively communicate with said gas conduit; at least one actuator held by the delivery unit that selectively actuates to cause at least one of said plurality of MDI canisters to dispense medicine into said gas conduit; a control unit in communication with the at least one actuator that causes said at least one actuator to automatically actuate to cause each of said plurality of MDI canisters to dispense medicine into said gas conduit in a defined sequence at defined intervals, wherein the control unit is configured to automatically direct the at least one actuator to cause one or more of the canisters to dispense (i) at a different dose amount from a prior amount, (ii) at an adjusted dose frequency or (iii) at a different dose amount and frequency from a prior amount and frequency; and a display in communication with the control unit that provides an operator interface and presents, for a respective MDI canister, a number of doses remaining, time to next actuation, frequency of delivery and delivery status, wherein said plurality of MDI canisters are circumferentially spaced apart and engage an index table, wherein said index table rotates at defined intervals as signaled by said control unit, and wherein the MDI canisters are concurrently held by the index table so as to be substantially orthogonal and adjacent to said gas conduit at a medicine dispensing location, wherein at least one of the canisters has a different medicine than another one of the canisters.
