Drug delivery devices with a spinning nozzle
Various exemplary drug delivery devices with a spinning nozzle, drug products utilizing the same, and methods of using drug delivery devices with a spinning nozzle are provided. In general, a nasal drug delivery device configured to dispense a drug therefrom includes a spinning nozzle configured to facilitate the drug's ejection into a patient's nose. The spinning nozzle is located between a drug holder containing the drug to be dispensed and an opening of the drug delivery device through which the drug exits the drug delivery device. The spinning nozzle is configured to spin during the drug's delivery as the drug travels from the drug holder and out of the drug delivery device. The spinning nozzle includes a plurality of perforations therein through which the drug as a liquid is configured to pass. The spinning of the spinning nozzle causes the drug to exit the drug delivery device as a fine mist.

12 . A drug delivery device, comprising:
a tip configured to be positioned in a nose of a patient, the tip having an opening therein;
an air chamber containing air therein;
a nozzle located distal to the opening and proximal to the air chamber, the nozzle including a plurality of perforations therethrough;
a first seal member located between the air chamber and the opening and providing a seal therebetween;
a drug chamber containing a drug therein and located distal to the air chamber;
a second seal member located between the air chamber and the drug chamber and providing a seal therebetween; and
an actuator configured to be actuated to cause the first seal member to break and subsequently cause the second seal member to break;
wherein the breaking of the first seal member is configured to cause the air to flow proximally and thereby cause the nozzle to spin; and
the breaking of the second seal member is configured to cause the drug to be drawn proximally and pass through the plurality of perforations and then out of the opening.
13 . The device of claim 12 , further comprising a piercing element in fluid communication with the opening and configured to, in response to the actuation of the actuator, break the first seal member and to subsequently break the second seal member.
14 . The device of claim 13 , wherein the piercing element comprises a tubular needle.
15 . The device of claim 14 , wherein the nozzle is located in a hollow interior of the tubular needle.
16 . The device of claim 13 , wherein the nozzle is located proximal to the piercing element and distal to the opening.
17 . The device of claim 12 , further comprising a dispensing head that includes the tip; wherein the actuator includes a body that is seated in a socket of the dispensing head.
18 . The device of claim 12 , wherein the nozzle includes a plurality of vanes extending radially outward from a center point of the nozzle, the plurality of perforations are formed in the plurality of vanes, and the nozzle is configured to spin about the center point.
19 . The device of claim 12 , wherein the drug is one of ketamine, esketamine, naloxone, and sumatriptan.
20 . A drug delivery method, comprising:
breaking a first seal member of a nasal drug delivery device and thereby causing air located in the drug delivery device to flow proximally, the proximal flow of the air causing a turbine of the drug delivery device to spin; and
after breaking the first seal member and after the turbine has begun to spin, breaking a second seal member of the drug delivery device and thereby causing a drug to be drawn proximally by the proximal flow of the air, to then pass through the spinning turbine, and to then exit the drug delivery device through an opening in the drug delivery device.
21 . The method of claim 20 , wherein a drug holder includes an air chamber located distal to the first seal member and proximal to the second seal member such that breaking the first seal member allows air in the air chamber to flow proximally, and the drug holder includes a drug chamber located distal to the second seal member such that breaking the second seal member allows drug in the drug chamber to be drawn proximally.
