International ClassA61M 001/00AbstractA medication dispenser (2, 120) is used to directly fill a syringe (8, 134) with measured amounts of one or more liquid medications, typically two different types of insulin, from containers, such as vials (4, 6) and cartridges (230, 232, 234) each having a septum at one end; each cartridge has a pierceable piston (256) at the other end. The septum of each container is pierced by hollow liquid spikes (54) while hollow gas spikes (56) pierce the septum of the vial and the piston of the cartridge. Liquid is pumped out of the container and air is replaced into the container through the liquid and gas spikes. Two of the cartridges can contain a diluent (231) and a lyophilized component (233) respectively; the diluent in the first cartridge can be pumped into the second cartridge through a one-way valve to create a mixed pharmaceutical which is then pumped into the syringe, with or without another pharmaceutical.Field of SearchFILLING OR REFILLING OF DISPENSERSBy operation of means causing or controlling dispensing Expansible chamber of fluid pressure applying or controlling means Dispenser carried expansible chamber pump Container with follower Closure type with manually controlled vent System fluid used in seal or in valve or lift operation MULTIPLE PASSAGE FILLING MEANS FOR DIVERSE MATERIALS OR FLOWS With air inlet to liquid supply Filling with exhausting the receiver PLURAL CONNECTED RECEIVERS FILLED BY SERIAL FLOW Selectively utilized sources With common discharge Dumping or draining With puncturing connecting means Mounted on receiver With support for removable supply container Means for intermixing liquid with solid or different liquid Septum pierced by conduit Means broken, cut, pierced or torn to permit mixing Septum piercing conduit separate from body entering conduit Having means for metering material flow to or from body Including means for controlling piston stroke length By rachet and pawl By detent By rotatable means (e.g., micrometer, etc.) Material reservoir (e.g., cartridge, etc.) removably mounted in syringe Means for metering amount of content drawn from container Having hollow needle or spike for piercing container or container clossure Conduit with hollow needle or spike at each end thereof Pointed at both ends Mounted on one container and used to pierce another container or closure Container with piercable closure Material impelled by spring Spring drives piston Material conduit forced into body by spring Material supply means pierced by conduit Having plural material reservoirs With discharge assistant for each source Single, operable on material from all sources Unitary reciprocating | |
