drug reconstitution system

Abstract

The invention discloses a drug reconstitution device, which comprises a disposable liquid delivery unit (18) and a reusable control drive unit (16) removably connected with the liquid delivery unit, the liquid delivery unit comprising a housing body (26), a docking interface (30) configured to couple at least one of the first component container (2) and the second component container (4) with the housing (10), and configured to transfer liquid from the second component container A pump engine (28) and fluid flow system (36) delivering one ingredient container (2) to a second ingredient container (4). The control drive unit includes a pump drive (22) configured to drive the pump engine during a fluid pumping action, the pump drive including a transmission output coupling (34) that when the fluid delivery unit is connected to the control drive unit, the transmission output coupling Removably engages a drive input coupling (50) of a pump engine (28).

Description

technical field [0001] The present invention relates to a drug reconstitution system, particularly for reconstituting a drug from two components, where at least one of the components is a liquid. In particular, the other component may be in dry form, such as a lyophilized material. Background technique [0002] Some specific drugs are only available in lyophilized form, this is to increase the stability of the product for easier transport and storage. These products need to be dissolved before administering the product to a patient. There may also be other reasons for lyophilizing active substances or products rather than in liquid or solution form, such as lack of stability when in contact with oxygen or air. [0003] Typically, the lyophilized material is stored in a container, such as an ampoule or vial, and is sealed by a septum secured by a roll cap. In some cases, a separate container with the precise dose of diluent is shipped or sold together with the container co...
