GLASS DRUG CHAMBER FOR AUTOMATED OPHTHALMIC INJECTION DEVICE

摘要

A dispensing assembly has a glass tube assembly, a chamber housing, a needle, and a temperature control device. The glass tube assembly includes a glass tube with inner and outer surfaces and distal and proximal ends. A plunger is fluidly sealed to the inner surface of the glass tube at the proximal end, and a seal is located at the distal end of the glass tube. The chamber housing has an inner surface and an outer surface. The inner surface partially defines a chamber for receiving the glass tube assembly. The needle has sharp distal and proximal ends, traverses the chamber housing, and is fluidly coupled to the chamber. The temperature control device at least partially surrounds the chamber housing. The proximal end of the needle is arranged to puncture the seal when the glass tube assembly is pressed against the proximal end of the needle.
