    摘要： A method and apparatus for controlling the washing step in a blood centrifugation cell in which washing solution is introduced into the blood centrifugation cell and the cell contains compacted red cells and supernatant at the beginning of the washing step. The apparatus can comprise various sensors and a computer. The sensors sense and transmit to the computer three inputs. The first input is indicative of the total volume of blood that enters the cell during the filling step and the total amount of washing solution that enters the cell during the washing step. The second input is indicative of the hematocrit value of the blood introduced during the filling step. The third input is indicative of the geometric characteristics of the cell. Based on the inputs, the computer executes an algorithm that produces a first output that is the concentration of the supernatant in the supernatant-washing solution mixture.

    摘要： The invention is directed to a blood bag system, comprising a closed, sterile bag of substantially transparent, bio-compatible material, defining upper and lower ends; an infusion port at the upper end of the bag; an outlet port at the lower end of the bag; an inlet port at the lower end of the bag; a hemo-concentrator having an inlet port and an outlet port; a pair of inlet tubes fluidly connected to the hemo-concentrator inlet port; and a pair of outlet tubes fluidly connected to the hemo-concentrator outlet port. One of the inlet tubes is fluidly connected to the outlet port of the bag, and one of the outlet tubes fluidly connected to the inlet port of the bag. The other of the inlet tubes and the other of the outlet tubes are temporarily sealed (e.g., clamped) to prevent flow therethrough. The bag, the one outlet tube, the hemo-concentrator, and the one inlet tube thus form a closed fluid circulation circuit by which a pump can recycle the blood through the hemo-concentrator. One aspect of the invention includes a hemo-concentrator system and a specially adapted tubing set, for easily and quickly converting the hemo-concentrator from conventional use to use in the blood recovery method. Other aspects of the invention are directed to the combination of tubing set with hemo-concentrator, and to the tubing set itself.

    摘要： Red blood cell sensing systems and methods rely upon straightforward measurement geometries. The systems and methods comprise an incident light source, an optical sensor, and a blood collection tube. The systems and methods hold the blood collection tube a predetermined radial distance from the incident light source where a linear relationship exists between sensed reflected light measured by the optical sensor and red blood cell hematocrit in a range of at least 10 to 90. The systems and methods make possible accurate red blood sensing without use of special optical cuvettes, mirrors, or focusing lenses. The systems and methods also make possible the use of standard transparent plastic tubing, without reliance upon special optical cuvettes.

    摘要： A method and blood bag, whereby a substantial volume of concentrated whole blood can be quickly and easily recovered from the cardiopulmonary bypass (CPB) circuit of a patient immediately following cardiac or thoracic vascular surgery. This is achieved in an operating room, by transferring most of the blood in the CPB circuit into a sterile bag located in the surgical field, removing the bag with blood from the surgical field, and outside the surgical field, but preferably in the operating room, hemo-concentrating the blood in the bag, while the bag is fluidly connected to the bypass system hardware. A novel blood bag (or hemo-bag) system is especially adapted for use with the method of the present invention. The new hemo-bag system comprises a closed, sterile bag of substantially transparent, bio-compatible material, defining upper and lower ends. An infusion port is located at the upper end of the bag. An outlet port, an inlet port, and an IV line are situated at the lower end of the bag. A baffle is preferably located inside the bag, for directing upward flow entering the bag through the inlet port, away from the outlet port. Each of the ports and line terminate in connector structure, and can be opened or closed by way of conventional clips and caps.
