Abstract

A device for delivering medication is presented. The device has a conduit with an upstream end and a downstream end. The downstream end of the conduit delivers the medication. The device has a housing with an open end and an end forming a flat substrate. The housing receives a vial containing a liquid and having a stopper. The device also has a valve for releasing the liquid from the vial into the conduit. The valve can be opened and closed by a user of the device. To release the liquid a piston is utilized to exert pressure on the stopper of the vial and the liquid is dispensed through a needle into the conduit.

Claims

1. A medication delivery device, said device comprising:

a conduit with an upstream end and a downstream end, wherein the downstream end is designed to deliver medication;

a housing with a first end and a second end, wherein the first end is open and the second end forms a flat substrate and wherein the housing receives a vial, said vial containing a liquid and having a stopper;

a valve for releasing the liquid into the upstream end of the conduit, the valve being an intermediate between the flat substrate and the upstream end of the conduit, wherein the valve is biased closed until actuated and wherein the valve is located downstream of the housing;

a second substrate, wherein the second substrate is communicably coupled to the valve to effect a bias on the valve;

a piston, wherein the piston exerts pressure on the stopper; and

a needle that is inserted through the stopper and provides fluid communication between the vial and the upstream end of the conduit through the flat substrate and the valve such that the needle defines a channel through the piston.

2. The device of claim 1, further comprising a nozzle, wherein a substantial portion of the conduit is enclosed in an endotracheal tube defining a proximal end and a distal end and wherein the nozzle extends past the distal end of the endotracheal tube;

and the conduit is malleable such that it forms a shape that facilitates intubation.

3. The device of claim 1, further comprising:

a luer connection in fluid communication with the channel defined by the needle; and

a flow regulator in fluid communication with the luer connection, wherein the flow regulator is designed to receive an intravenous conduit.

4. The device of claim 3, wherein the flow regulator is a pressure-independent regulator.

5. The device of claim 1, wherein the piston extends from the flat substrate.

6. The device of claim 1, wherein the piston is slidably received by the housing such that a compression chamber is formed between the base of the piston and the flat substrate and wherein the flat substrate has a through channel in fluid communication with the valve.

7. The device of claim 1, wherein the piston is a spring contained within the vial and positioned downstream of the stopper.

8. The device of claim 1, wherein the piston is a spring interspaced between the flat substrate and the stopper.

9. The device of claim 1, wherein the piston is a stationary ram extending from the housing, wherein a one way valve is disposed within the ram and upstream from the valve, and wherein a second one way valve is disposed between the valve and the conduit.

10. The device of claim 1, wherein a length of flexible tube separates the housing and the valve and wherein the conduit is in a second needle, wherein the second needle having a beveled edge for piercing a surface.

11. The device of claim 1, further comprising:

a solenoid valve, the solenoid valve communicably coupled to the valve, wherein when the solenoid valve is actuated the valve is biased open to allow the liquid to flow from within the housing through the valve into the conduit for delivery of the medication; and

a button, the button communicably coupled to the solenoid valve, said button producing a wireless communication that actuates the solenoid valve.

12. The device of claim 1, further comprising:

a handle;

the handle having a proximal end and a distal end;

the proximal end of the handle coupled communicably to the valve, wherein when pressure is applied to the distal end of the handle the valve is biased open to allow the liquid to flow from within the housing through the valve into the conduit for delivery of the medication.
