FREEZE-DRY POWDER INJECTOR RESTORING DEVICE

Abstract: a freeze-dry powder injector restoring device includes a container, a piston, and a top cover. the container has a lower connecting portion, a cup body, and a tube portion. the tube portion is mounted in the cup body. the tube portion has a tube opening. the piston has a separating board and a connecting sleeve. the piston is slidably mounted on the tube portion and divides the inner space into a first chamber and a second chamber. multiple communicating channels are formed between the first chamber and the second chamber. when the tube opening is closed, the communicating channels are closed, and when the tube opening is open, the second chamber fluidly communicates with the first chamber. the top cover covers on the cup body. the freeze-dry powder injector restoring device meets a requirement of freeze-drying locally in the original container and assembling on the production line.
