In a blood reservoir comprising a hollow housing and filtration/defoaming and blood collecting sections therein; the blood collecting section is located below and separated from the filtration/defoaming section receiving bubbled blood and has a sufficient capacity, typically 500 to 2,500 ml, to keep blood collected therein out of contact with the filtration/defoaming section; guide means in the form of a cone-shaped deflector is disposed between the filtration/defoaming section and the base of the housing to lead along its inner surface defoamed blood from the filtration/defoaming section to the collecting section without dripping. The filtration/defoaming section includes a concentric assembly of a pleated filter, a tubular member inwardly spaced apart from the filter to define a blood channel inside and to define a space outside for allowing bubbles to separate from the blood, a defoaming member about the filter, and a cylindrical distributor member inside the filter and extending through the tubular member, the tubular member protecting the upper portion of the filter from being wetted with blood.

A device for receiving and treating blood, comprising a hollow housing having a top, a base, inlet means and an outlet, said inlet means being opened at the housing top for introducing blood into the housing and said outlet being opened at the housing base for discharging blood out of the housing, an upper filtration/defoaming section disposed in said housing for filtering and defoaming blood from said inlet means, said filtration/defoaming section including: a tubular filter, a tubular member defining a blood channel in communication with the blood inlet at the housing top and disposed inside said tubular filter to extend a part of the axial length of said tubular filter for protecting the upper portion of said tubular filter from being wetted with blood, said tubular member being spaced apart from said tubular filter to define a space for allowing bubbles to separate from the blood, and a defoaming member disposed about said tubular filter, a lower blood collecting section defined in said housing adjacent to its base for collecting blood, the blood in said collecting section discharging out of the housing through the outlet, and guide means extending between said filtration/defoaming section and the housing base and shaped to converge from said filtration/defoaming section toward the center of said housing base, said guide means including a convergent inner surface for continuously leading blood that has been filtered and defoamed in said filtration/defoaming section to the housing base along the inner surface without dripping.
