The first actuator arm (132a) has a first protrusion (150a) depending therefrom and the second actuator arm (132b) has a second protrusion (150b) depending therefrom. The first actuator arm (132a) and the second actuator arm (132b) are pivotable from the first position towards one another to a second position, or actuating position, that is configured such that the first protrusion (150a) engages the outer container (14) and the second protrusion (150b) engages the outer container (14) to crush the glass ampoule (12) wherein the flowable material (M) is configured to be dispensed from the glass ampoule assembly (10).
Apparatus and method for monitoring and controlling the removal of a cover from a sealed tube in an aseptic environment
A system is presented for monitoring and controlling in a sterilizable environment the peeling of a cover from a tub sealed by the cover. The system employs a platform having a fiducial source locating structure for holding the tub, a cover removal station disposed to engage with the cover and to peel the cover from the tub, a light source disposed to illuminate a portion of the platform proximate the cover removal station, a light sensor sensitive to light from the light source and disposed to preferentially collect and measure light diffusely reflected from the illuminated portion of the platform, and a controller with software to operate the system. An associated method for monitoring and controlling the peeling of the cover involves moving a peeled portion of the cover into a predetermined peeling monitor zone within the illuminated portion of the platform, and measuring an intensity of light from the light source diffusely reflected specifically from the peeling monitor zone. The positioning of the elements of the system and the peeling monitor zone allow measured light intensity to be employed as a control measure for the peeling process.
Method of mixing a pharmaceutical solution and mixing system
A method of mixing a pharmaceutical solution including adding a gas into an interior compartment of a mix bag to form a headspace. The interior compartment of the mix bag includes a top portion and a bottom portion. The headspace adjacent to the top portion contains gas. The method includes adding a solvent into the mix bag, and establishing a bubble column in the interior compartment by activating a recirculation assembly. The recirculation assembly includes a connecting pathway operably coupled to a recirculation pump. A first end of the connecting pathway is coupled to a top gas recirculation port and a second end is coupled to a bottom gas recirculation port of the mix bag such that the recirculation pump draws the gas from the headspace and delivers the gas to the interior compartment via the bottom gas recirculation port. The method includes adding a solute into the mix bag.
SYSTEM FOR DETERMINING ACCURACY OF SERIALLY-CONNECTED DRUG MODULES IN A COMBINATORIAL DRUG DELIVERY DEVICE USING VOLTAGE
A combinatorial drug delivery device is provided herein including: a plurality of serially connectable modules, each including at least one drug component; and, a master controller. Each of the modules includes: a power line; a ground line; a multiplexer having a plurality of identified input channels, at least a subset of the input channels being selectively connected to one of the power and ground lines; a first digital logic line configured to select the input channels; a voltage reference line having a first resistor in line with an output of the multiplexer; a branch line connected to the voltage reference line having a normally closed switch thereon to connect the branch line to the ground line, the switch being opened with connection to a further module. The master controller selects, in sequence, the same identified input channels across all of the modules with measuring a reference voltage thereacross.
Connector
There is provided a connector, for introducing or extracting a material to or from at least one receptacle, comprising a housing extending between a distal end and a proximal end, the housing comprising, at least at one end, a pierceable seal; a hollow needle mounted, at least partially, within the housing between the distal end and the proximal end of the housing, a first end of the hollow needle being connected or connectable to a first corresponding receptacle, and a second end of the hollow needle facing the pierceable seal at an end of the housing; and an actuating mechanism acting on the housing or the hollow needle to enable the hollow needle to pierce the pierceable seal thereby forming a communication through the pierceable seal, such that material is able to transfer through the connector.
Drug delivery device
A drug delivery device comprising a delivery unit (2) including an internal reservoir (8), a subcutaneous delivery mechanism (6), a pump for pumping liquid from the internal reservoir to the subcutaneous delivery system, and a liquid filling mechanism (12) configured for injecting liquid from an external vial (16) or reservoir into the internal reservoir.

The valve mechanism comprises a valve housing (48) fixedly mounted in relation to a housing of the drug delivery device and a valve stem (50) rotatably received within the valve housing, whereby the first fluid path and the second fluid path are selectively operated by the rotational position of the valve stem in relation to the valve housing, such that when the valve stem is in a first position, the first fluid path is open while the second fluid path is closed, and when the valve stem is in a second position, the second fluid path is open while the first fluid path is closed.
Filtration system for preparation of fluids for medical applications
A system for filling multiple sterile containers includes a filter with an inlet port and multiple outlet ports, the outlet ports being pre-attached to sterile containers by respective filling lines of each container. Each container has an interior and each of the respective filling lines are connected to a respective container interior. The respective filling lines are sealed to the outlet ports and the containers such that the container interiors are isolated from an external environment except the inlet port, via the filter, forming a combined interior volume which is sterile. A container that is connectable to an outlet port the system has a bladder, a first tube and a second tube connected to the bladder, and a sterilizing filter. The container, the first tube and the second tube, and the sterilizing filter are sterile before water is flowed through the sterilizing filter into the bladder.
