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; and
a 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; and
an 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.

Abstract
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.

16. A system for delivering drug, comprising:
-
an adapter configured to establish fluid communication with a gas conduit of a ventilator circuit; and a 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; and an 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; and a 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; and a 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; and the 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.
