Abstract: The nasal sprayer utilizes a piston that fires automatically upon full depression of the firing cap. The drive spring does not fire the piston until fully compressed because the force required to break a puncturable medicine container is greater than to compress the spring. The piston height is greater than the firing cap and central member height combined so that after the spring is fully compressed, the piston punctures the medicine container. The spring then releases, pushing the piston toward the nozzle. A user procures medicine from the device by (i) unlocking a child resistant lock; (ii) applying compressive force against the firing cap to compress the spring and to push the piston to puncture the medicine container, then the spring causes the distal end of the piston to drive medicine through the spray nozzle independent of the user as to dosage amount and speed of delivery.
