Abstract
A handpiece assembly is provided that is adapted for use with a medication infusion system that applies pressure to the handpiece assembly for delivering medication to a body. The handpiece assembly includes a cartridge holder that is configured for disposal of a medication cartridge. A tubing is provided having a first end, which is sealed with the cartridge holder such that the cartridge holder facilitates communication between the tubing and the medication cartridge. A handpiece is sealed with a needle and the second end of the tubing so that the tubing and the needle are in communication. One of the cartridge holder, the tubing, the needle or the handpiece is configured for a selective structural failure at a predetermined pressure threshold applied to the handpiece assembly from the medication infusion system. The cartridge holder may be designed to facilitate aspiration.
