A method of preparing a pharmaceutical product in a single multiple chamber flexible bag. A pharmaceutical product is introduced in a liquid state into a first chamber of the flexible bag through a first port. The pharmaceutical product is lyophilized within the first chamber of the flexible bag to provide a lyophilized pharmaceutical product. The flexible bag has a second chamber and the first chamber and the second chamber are separated by a breakable seal. The second chamber further includes a reconstituting solution for reconstituting the lyophilized pharmaceutical product in the first chamber. A user may apply pressure to the flexible bag to break the seal and mix the lyophilized pharmaceutical product and the reconstituting solution to order to administer the pharmaceutical product to a patient.

A kit for flushing internal channels of an endoscope includes a sealing plug for engagement with an air/water cylinder of an endoscope, a detergent delivery assembly for connection to a water bottle connector of the endoscope, and a cleaning apparatus with a bag holding liquid. The sealing plug seals an air inlet of the air/water cylinder and to permit fluid flow between a water inlet of the air/water cylinder and both an air outlet and a water outlet of the air/water cylinder simultaneously. The detergent delivery assembly includes a bag holding liquid, a first fluid conduit extending out of the bag for connection to the water bottle connector, and a second fluid conduit extending out of the bag for connection to the water bottle connector. The bag of the cleaning apparatus has a neck portion for insertion of the endoscope into the bag.

A flexible pharmaceutical bag includes a first chamber holding a lyophilized pharmaceutical product, a second chamber separated from the first chamber, and a third chamber separated from one of the first and second chambers. The second chamber holds a reconstituting solution for reconstituting the lyophilized pharmaceutical product in the first chamber. The third chamber holds a solution. The flexible pharmaceutical bag includes a seal disposed between the first chamber and the second chamber. The seal separates and seals the first chamber from the second chamber. The flexible pharmaceutical bag includes a first port attached to the first chamber. The first port introduces a pharmaceutical product into the first chamber and allows passage of water vapor from the pharmaceutical product during lyophilization of the pharmaceutical product. The third chamber is separated from one of the first and second chambers by a valve.

A bag for producing a foam-in-bag dunnage material comprises a closed edge portion and, in a non-sealed state of the bag, an open edge portion, the closed and open edge portions delimiting an inner bag volume. The invention proposes that a bag structure of the bag comprises a mixing chamber which is adapted to receive foam precursor substances, which is arranged within the inner bag volume, which is at least partially and initially delimited against the remainder of the inner bag volume, and which in the non-sealed state of the bag is connected to the open edge portion.

A multiple chamber flexible pharmaceutical bag includes a front film and a back film joined to the front film around a perimeter of the pharmaceutical bag to define a first chamber holding a lyophilized pharmaceutical product and a second chamber holding a reconstituting solution for reconstituting the lyophilized pharmaceutical product held in the first chamber. The pharmaceutical bag includes a seal disposed between the first chamber and the second chamber and defining a connection between the front film of the pharmaceutical bag and the back film of the pharmaceutical bag. The seal breaks when a predetermined amount of force is applied to the pharmaceutical bag such that the connection between the front surface and the back surface of the pharmaceutical bag is torn apart to fluidly connect the second chamber to the first chamber. The front film, the back film, and the seal are comprised of the same material.
