Embodiment Construction

[0021] Such as figure 1 As shown, the centrifuge shaft 1 of the centrifuge 16 of the preparation device is cylindrical and segmented, and is screwed into the whole shaft 1 by the joint screw rod 2 and the joint screw hole 2'; the upper end of each joint shaft 1 has a section The regular quadrilateral axis is inscribed in the circle, and the length of the regular quadrilateral axis of the bottom section axis 1 is equal to the depth of the regular quadrilateral hole in the center of the blood collection bag tray 14; ; Except for the uppermost shaft, there is a section of joint screw rod 2 on the plane of the upper end of the regular quadrilateral shaft 1 of other joint shafts 1; The height should be greater than the depth of the regular quadrilateral hole in the center of the collection bag tray. Except for the lowermost joint shaft 1, the lower ends of the other joint shafts 1 have joint screw holes 2' that match the joint screw rod 2 of the previous joint shaft 1.

Abstract

The invention discloses a blood component preparation method and a preparation device thereof. A blood gathering bag tray with a pressing mechanism and a collecting bag tray are installed on a centrifuge shaft, and a blood collecting trigeminy bag is arranged on the tray. Blood centrifugation and separation and blood component collection are automatically and synchronistically accomplished, and the operation process of the centrifuge, the tray and a blood bag control clamp are manually controlled during the preparation process. The centrifuge is started to ensure the whole blood in the blood gathering bag to be centrifuged at high speed, after delamination appears, an air cell expands to press an elastic tray and the blood gathering bag, blood plasma and blood platelet in the upper layer are pressed into the collecting bag, then the pressing is stopped and the centrifuge is stopped when a set quantify is achieved; and red corpuscle preservative fluid is added into the blood gathering bag. The high purity separation of the blood component is realized, the system is completely closed and pollution free, and the quality of the blood component is high; the separation efficiency of thewhole blood is high, and thereby the large scale multi-bag separation and the collecting operation are convenient; the key process is mechanized, the auxiliary process is artificial, and the working strength is small.

Description

technical field [0001] The invention belongs to the field of a blood component preparation device and a preparation method, and in particular relates to a blood component preparation device and a preparation method. Background technique [0002] Blood stations need to prepare whole blood into blood components whether they are storing blood (the storage conditions of blood components are different) or transfusion of patients, which greatly improves the utilization of precious blood resources. The whole blood collected by the blood bank is mainly composed of plasma, red blood cells, platelets and white blood cells. [0003] At present, centrifuges and blood component separators are mostly used for the separation and preparation of large quantities of blood components. However, centrifuges and blood component separators are independent equipment. Blood centrifugation and blood component collection cannot be completed simultaneously. Usually, the whole blood is centrifuged first...
