摘要:
A disposable urine bag having sealed cavity members where one cavity stores an extendable catheter and also acts as a urine storage reservoir. A second sealed and peel-away cavity includes a catheter advancement mechanism which provides for lubricated catheter advancement without actual contact of the catheter by the human hand. An absorption member is provided to semi-solidify urine stored in the urine storage reservoir.

A versatile compartmentalized cell culture device, with a selectively permeable membrane separating the compartments, provides many attributes relative to traditional devices. It can be configured for high-density cell culture, co-culture, and sample dialysis while rolling or standing still. It can also be configured for continuous movement of liquid between compartments. The wide combination of attributes not found in other membrane based cell culture and bioprocessing devices includes more cell capacity, more cell secreted product capacity, higher cell and product density, increased medium capacity, minimized use of exogenous growth factors, compatibility with standard cell culture equipment and protocols, increased scale up efficiency, capacity to function when rolling or standing still, capacity for perfusion without the need for pumps, and more efficient sample dialysis.
摘要:
This invention relates to methods and devices that improve the process of culturing cells and/or shipping cells from one location to another. They have the capacity to reduce the risk of contamination, regulate pressure in the medium surrounding cells, and maintain cells in a uniform distribution throughout transit. This leads to an improved level of process control relative to current methods.
摘要:
Gas permeable devices and methods are disclosed for cell culture, including cell culture devices and methods that contain medium at heights, and certain gas permeable surface area to medium volume ratios. These devices and methods allow improvements in cell culture efficiency and scale up efficiency.
摘要:
An internal ring releasing device including a housing, a cylindrical adaptor at one end, piston within the housing and a primary insert in the other end of the housing. The piston includes a constriction ring groove for holding a constriction ring. The piston is caused to move from a load position with a constriction ring to an unload position where the constriction ring slides off around the base of an erect penis.

A quick connect coupling (20) for fluid tight connection to a threaded fluid port (22). A body (26) of the quick connect coupling (20) having a cylindrical, externally threaded first end (28) defining an axially extending passage (29) into the coupling body (26). Axially slidable sleeve (42) being mounted on the outside of the coupling body (26) for slidable motion between a seal unassisted position and a seal assisted position, the axially slidable sleeve (42) forcing against an elastomeric seal (30) in the seal assisted position so as to provide a fluid tight seal between an end of the fluid port (22) and the coupling (20).
