ABSTRACT:
An apparatus for handling blood or other material between the time a sample thereof is removed from the patient and the time the sample is presented to the laboratory for placement on a slide or in other test structure for analysis. More specifically, a blood handling container basically cylindrical in shape and rigid enough in construction to be evacuated and with a mid-section that is flexible after filling the container with blood. The flexible section may be chemically different from the end portions or having structurally different shapes such as ribbed support members. Said device being air tight so as to be capable of maintaining a vacuum therein. One or both the ends of said device being composed of a stopper such as rubber or other useful material that is easily pierceable by a hollow needle for filling or discharging. The device is utilized by having the hollow needle placed within but not through the rubber end and then placing the opposite end of the needle in a vein or artery and then forcing the needle through the stopper. The vacuum within the container causes the blood to flow quickly from the vein to the device. The container is then centrifuged separating the blood into two or more components and a specially designed separation means such as a clip is placed on the flexible mid-section of the container to prevent the components from reacting or remixing during transportation.
