ABSTRACT:
A membrane device having particular utility as a blood oxygenator is disclosed. The device comprises a housing having an oxygen inlet and outlet, a blood inlet and outlet, and a water inlet and outlet. A plurality of blood modules and water modules are arranged in a predetermined configuration in the housing. Each of the blood modules is in flow communication with the blood inlet and outlet on the housing and defines a flow path for the blood through the housing and across each of the blood modules. The water modules are in flow communication with the water inlet and outlet on the housing and define a flow path for the water through the housing and across each of the water modules. The blood modules and water modules are arranged and configured in a specific and predetermined configuration so as to form a pathway for introducing oxygen between adjacent modules. By the use of the membrane device of the present invention, problems of accidental rupture of either a blood module or a water module is substantially reduced. In addition, should such an accidental rupture take place, the flow path of the leakage through the device is such that it is extremely unlikely for water and blood to mix.
