BODY FLUID FILTRATION DEVICE AND APPLICATION THEREOF

摘要

Device including a filter bag for separating a liquid phase from a suspended solid phase in a body fluid. In said filter bag, a sheet filter (5) defines an upstream (7a) and a downstream (7b) section connectable by suitable tubing to a source of said body fluid and to a container for receiving the filtrate. The filter (5) may be integrally rigidly mounted in the device, or subsequently stiffened, and the device can be used with the filter in a vertical position, with the source located above and the container under the filter bag, and the fluid is gravity-fed. The walls (6a) and (6b) of the filter bag, defining the upstream and downstream sections, are made of a flexible film. With this device, a cryoprecipitate, such as an autologous cryoprecipitate usable as a biological adhesive, can be easily and efficiently filtered without the risk of filter clogging.
