A system for delivering drug is provided. The system includes an adapter and a device. The adapter is configured to establish fluid communication with a gas conduit of a ventilator circuit. The device includes an actuation member and an actuator. The actuation member is configured to pivot. A canister containing drug is disposed between the adapter and the actuation member. The actuator is engaged to the actuation member such that the actuator selectively causes pivotal movement of the actuation member, causing the actuation member to apply pressure over the canister, thereby causing the canister to deliver drug into the adapter.

1. A system for delivering drug, comprising: an adapter configured to establish fluid communication with a gas conduit of a ventilator circuit, wherein the adapter comprises a first end and an opposite second end, the first end configured to engage a first tube of the gas conduit and the second end
1. A system for delivering drug, comprising: an adapter configured to establish fluid communication with a gas conduit of a ventilator circuit, wherein the adapter comprises a first end and an opposite second end, the first end configured to engage a first tube of the gas conduit and the second end configured to engage a second tube of the gas conduit such that the adapter is in-line with the first and second tubes; anda device comprising: an actuation member, wherein the actuation member is configured to pivot, and wherein a canister containing a drug is disposed between the adapter and the actuation member; andan actuator engaged to the actuation member such that the actuator is configured to selectively cause pivotal movement of the actuation member, causing the actuation member to apply pressure over the canister, thereby causing the canister to deliver the drug directly into the adapter;wherein the actuation member comprises a contact member configured to interface with the canister, the system further comprising a height adjustment member comprising a rotatable member at a bottom portion of the device that is operatively connected to the actuation member, wherein the rotatable member is configured to be rotated in a first direction to move the actuation member in a first direction such that the contact member contacts the canister and in a second, opposite direction to move the actuation member in a second direction such that the contact member is spaced apart from the canister. 2. The system of claim 1, further comprising a housing, wherein the housing is configured to at least partially encase the actuation member, and wherein the housing is configured to be engaged to the adapter. 3. The system of claim 2, wherein the adapter comprises a housing engagement feature and the housing comprises an adapter receiving feature, and wherein the housing engagement feature is configured to engage the adapter receiving feature such that the adapter is releasably engaged with the housing. 4. The system of claim 1, wherein the actuation member comprises: a housing;anda sensing member between the housing and the contact member, the sensing member configured to sense an amount of force exerted on the canister. 5. The system of claim 4, wherein the contact member is configured to apply pressure over the sensing member as a result of pivotal movement of the actuation member that causes the actuation member to apply the pressure over the canister. 6. The system of claim 4, wherein the contact member is configured to traverse towards the sensing member when the contact member is pressed against the canister. 7. The system of claim 6, wherein the actuation member further comprises an intermediate member, wherein the intermediate member is disposed between the sensing member and the contact member, wherein movement of the contact member towards the sensing member is limited by the intermediate member. 8. The system of claim 1, wherein the actuation member is configured to pivot away from the adapter at least when the actuation member is not interfacing the canister. 9. The system of claim 1, wherein the actuation member is configured to pivot about a pivot shaft, and a portion of the actuation member disposed towards the actuator from the pivot shaft is heavier than a portion of the actuation member disposed towards the canister from the pivot shaft. 10. The system of claim 1, wherein the actuation member and the adapter are configured such that distance between the actuation member and the adapter is operatively altered. 11. The system of claim 10, wherein the actuation member and the adapter are configured such that reduction of distance between the actuation member and the adapter is prevented once a force applied on the canister reaches a predefined threshold. 12. The system of claim 1, further comprising a controller that is configured to: (i) receive input from a gas flow sensor disposed in the gas conduit and/or the ventilator circuit; and (ii) direct the actuator to cause pivotal movement of the actuation member in response to receiving input from the gas flow sensor. 13. The system of claim 1, wherein the adapter defines a longitudinal axis between the first and second ends of the adapter, and wherein the adapter longitudinal axis is parallel to a pivot axis of the actuation member. 14. The system of claim 1, further comprising a support member engaging the actuation member, wherein the rotatable member comprises a knob, and wherein the height adjustment member comprises a screw coupled to the knob and engaging the support member. 15. The system of claim 1, wherein the actuation member comprises: a first end adjacent the canister;a second end adjacent the actuator;a pivot shaft between the first and second ends; andat least one weight increasing member between the second end and the pivot shaft. 16. A system for delivering drug, comprising: an adapter configured to establish fluid communication with a gas conduit of a ventilator circuit; anda device comprising: an actuation member, wherein the actuation member is configured to pivot, and wherein a canister containing a drug is disposed between the adapter and the actuation member; andan actuator engaged to the actuation member such that the actuator is configured to selectively cause pivotal movement of the actuation member, causing the actuation member to apply pressure over the canister, thereby causing the canister to deliver the drug into the adapter,wherein the actuation member and the adapter are configured such that distance between the actuation member and the adapter is operatively altered,wherein the actuation member and the adapter are configured such that reduction of distance between the actuation member and the adapter is prevented once a force applied on the canister reaches a predefined threshold,the system further comprising:a support member, wherein the actuation member is engaged with the support member, and wherein the support member defines a threaded hole; anda height adjustment member, wherein the height adjustment member comprises: a screw comprising a shaft and a head, wherein at least a part of the shaft defines a threaded portion configured to mate with the threaded hole of the support member; anda knob, wherein one of the head and the knob comprises at least one engagement arm, and the other defines at least one engagement notch, wherein the engagement arm is received by the engagement notch such that: the engagement arm is engaged in the engagement notch, irrespective of the torque required for rotating the screw, when the knob is rotated in a first direction resulting in increasing of the distance between the actuation member and the adapter; andthe engagement arm is engaged in the engagement notch only until a particular limit of torque is applied to the head, and thereafter the engagement arm starts slipping with respect to the knob when the knob is rotated in a second direction resulting in decreasing of the distance between the actuation member and the adapter.
