Apparatus and method for separating blood components
First Claim
1. An apparatus for separating blood components by means of sedimentation action due to gravitational force, comprising:
- a first empty space provided with an opening for a feed line of blood;
a component separation portion connected with said empty space, the inside of the separation portion forming a plurality of flat flow channels having a thickness of not more than 20 mm.; and
a second empty space provided with at least two openings for discharge lines of the separated blood components.

Abstract
An apparatus and method for effectively and efficiently separating blood components by means of sedimentation action due to gravitational force are disclosed. The blood to be separated is continuously passed through a blood flow channel comprising plural flat empty spaces each having a thickness of, for example, 20 mm or less, or a plurality of tubular empty spaces each having a sectional area of, for example, 3 cm or less. An opening for a feed line is provided in a first empty space of the apparatus and two or more openings for discharge lines of the separated blood components are provided in a second empty space. These empty spaces are connected with the blood flow channel.

9. A method for separating blood components by means of sedimentation action due to gravitational force, comprising the steps of:
-
continuously passing blood to be separated through a blood flow channel comprising at least two flat empty spaces having a thickness of not more than 20 mm, said blood containing an added water-soluble polymer, while the blood flow channel is filled up; separating the blood flow into multiple streams of the separated blood component layers; and collecting the desired blood component layer or layers. - View Dependent Claims (10)
