の問題点があった。2. Description of the Related Art Conventionally, there are several types of blood chambers, and chambers having a structure for separating blood from physiological saline have been tried. However, when the air enters, there is a problem that the separated physiological saline and blood are mixed.

る。In the chamber of the present invention, by providing an upper filter on the chamber, physiological saline filled in the chamber above the upper filter is not agitated by circulating blood and air is flowed from the lower chamber to the upper chamber. It can be floated and can keep the separated state.

ため血液の分離状態を５時間保つことができた。EXAMPLE Actually, the same blood separation chamber as that of FIG. 1 was created, and physiological saline was filled into the upper chamber, and then blood was circulated at 200 ml / min using a blood pump.
By providing a filter (2) on the lower upper part on the lower chamber (1), when air flows in from the blood inlet (6), it was separated from the physiological saline in the lower chamber (1). The blood is agitated by the inflow of air, but the air stops at the lower upper filter (2) and gradually floats to the middle chamber (3), and the blood and air float to the middle chamber (3). Even so, because of the presence of the middle upper filter (4), the air again stops at the middle upper filter (4), and the air gradually rises to the upper chamber (5), so it is filled with saline. Blood hardly floated in the upper chamber (5), and the air floated with almost no effect on the stirring, so that the blood separation state could be maintained for 5 hours.

療上有効である。Most of the blood coagulation in the blood chamber is due to the direct contact between the air in the chamber and the circulating blood. According to the above experimental results, the air in the chamber is provided by installing a filter above the blood inlet. Slowly rises to the upper chamber, and the upper chamber is kept in a separated state with almost no contact with blood, so that blood coagulation can be prevented beforehand. If blood coagulation is difficult, the amount of anticoagulant required for extracorporeal circulation can be reduced, which is therapeutically effective.
