Transfer system for forming a drug solution from a lyophilized drug
A transfer system ( 100, 100′, 100 ″) adapted to allow first contents of a first container ( 20 ) and second contents of a second container ( 30 ) to mix to form a material. The mixed material is retrieved to a syringe ( 40 ). The transfer system ( 100, 100′, 100 ″) comprises first ( 17 ) and second ( 18 ) flow control members for controlling fluid flow between the containers ( 20, 30 ) and the syringe ( 40 ). The invention further relates to a drug mixing kit comprising a container unit containing first and second containers, and a transfer unit comprising ports for receiving the containers and a syringe and a number of flow channels. The container unit and the transfer unit are adapted to be coupled together to form a drug mixing kit.
1. A drug mixing kit comprising:
a container unit comprising:
a first container, said first container containing first contents, and
a second container, said second container containing second contents to be mixed with the first contents to form a material, and
a transfer unit comprising:
first and second ports adapted to receive first and second containers of a container unit, and
a third port for coupling to a syringe, the transfer unit further comprising a number of flow channels, at least some of the flow channels pair-wise interconnecting two of the first port, the second port and the third port,
a flow control member enabling one-way fluid flow through a flow channel from the second port to the third port, and
a flow control member enabling one-way fluid flow through a flow channel from the third port to the first port,
wherein the container unit and the transfer unit are adapted to be coupled together to form a drug mixing kit.
2. A drug mixing kit according to claim 1 , wherein the container unit and the transfer unit are shaped in such a manner that they can only be coupled together when being positioned at a predetermined mutual orientation.
