Insufflation apparatus and methods

1. A dry powder drug delivery system, comprising:

a single platform structurally configured for receiving an anesthetized animal and mounted on a stand comprising a base and support beams adapted with a hinge configured to hold said single platform, and a shaft configured to hold and support an air pump comprising: said air pump

adapted with a linear solenoid, and a powder reservoir; wherein said linear solenoid is actuated by an onboard relay output system to pressurize a syringe pump at a predetermined interval during an inhalation to release a powder plume from the powder reservoir;

a drug delivery device adapted to said air pump and comprising a cannula for positioning in a mouth and a chamber for containing a dry powder drug composition;

an adjustable strap comprising one or more sensors for detecting breathing cycles of the anesthetized animal, wherein at least one of the one or more sensors is an accelerometer, a microphone, a thermistor, and/or a transducer;

a data acquisition board comprising an executable algorithm for analyzing and transmitting signals from said one or more sensors and determining and displaying the anesthetized animal's breathing pattern, wherein said executable algorithm contains instructions to actuate said linear solenoid at a predetermined interval of a breathing cycle of said anesthetized animal and delivers an aerosolized dry powder composition to the anesthetized animal during an inhalation; and

wherein said single platform comprises a hanging wire, neck support posts, and said adjustable strap to position said anesthetized animal on said single platform.

2. The system of claim 1 , including a second sensor configured to detect the anesthetized animal's breathing.

3. An apparatus, comprising:

a first device comprising a single platform comprising an animal positioning area comprising a hanging wire and neck support posts to support and align a neck of an anesthetized animal and an adjustable strap including one or more sensors which detect distention of said anesthetized animal's abdomen and/or thorax due to breathing, generates an input signal and communicates the input signal to a microprocessor for analysis wherein at least one of the one or more sensors is an accelerometer, a microphone, a thermistor, and/or a transducer wherein said adjustable strap is positioned over a diaphragm of said anesthetized animal; and

a second device comprising a linear solenoid, a syringe pump and a drug delivery device adapted to an air pump and comprising a cannula for positioning in a mouth and a chamber for containing a dry powder drug composition;

wherein said linear solenoid is actuated by an onboard relay output system to pressurize the syringe pump;

wherein said second device further comprises a computer interface comprising a programmable algorithm which detects, analyzes and sends instructions of the anesthetized animal's breathing pattern and actuates said linear solenoid to pressurize the syringe pump at a predetermined interval during an inhalation to release a powder plume from the chamber

wherein said single platform is mounted on a stand comprising a base and support beams adapted with a hinge configured to hold said single platform, and a shaft configured to hold and support said air pump.

4. The apparatus of claim 3 , further comprising a mount to secure said single platform.

5. The apparatus of claim 3 , wherein said first device further comprises a second sensor, which is configured to detect the anesthetized animal's breathing.

6. An insufflation method comprising:

positioning an anesthetized animal on a single platform of an insufflation apparatus comprising an automated air pump syringe adapted with a linear solenoid and a drug delivery device comprising a cannula for positioning in a mouth and a chamber for containing a dry powder drug composition wherein said single platform includes a hanging wire and neck support posts to support and align a neck of said anesthetized animal, and an adjustable strap, and is mounted on a stand comprising a base and support beams adapted with a hinge configured to hold said single platform, and a shaft configured to hold and support said air pump syringe;

placing said adjustable strap comprising one or more sensors on or near the anesthetized animal to detect breathing signals of said anesthetized animal, wherein the sensors are configured to detect and transmit the breathing signals and communicate with a data acquisition board, and wherein at least one of the one or more sensors is an accelerometer, a microphone, a thermistor, or a transducer wherein said adjustable strap is positioned over a diaphragm of said anesthetized animal; and

analyzing the breathing signals from the anesthetized animal's breathing cycles to determine and analyze the anesthetized animal's breathing rate and cycles in real-time using a microprocessor with an executable algorithm, and administering a dose of the dry powder drug composition at an inhalation interval by actuating the linear solenoid to generate a predetermined force at a predetermined interval of an inhalation of the anesthetized animal's breathing cycle.

7. The method of claim 6 , wherein actuating the linear solenoid is carried out from signals from a computer interface comprising a programmable algorithm.

8. The method of claim 6 , wherein actuating the linear solenoid generates air pressure in the air pump syringe which discharges the dose of a test composition.

9. The method of claim 6 , further comprising intubating the anesthetized animal with the cannula from the insufflation device.

10. The method of claim 6 , wherein placing of the one or more sensors on or near the anesthetized animal is automated.
