Abstract

The invention belongs to the field of devices for blood component separation, and relates to a centrifugal bag type blood component separator. The centrifugal bag type blood component separator comprises a double-layer flow path integration device, the double-layer flow path integration device communicates with an anticoagulant bag, a saline bag, a whole blood bag, a erythrocyte bag, a plasma bag, a blood platelet bag and a centrifugal bag; the double-layer flow path integration device comprises an upper cover plate, a middle integrated body and a lower cover plate, wherein the middle integrated body comprises an outer shell; the inner part of the outer shell is partitioned into an upper layer and a lower layer by a middle partition plate; an anti-coagulant pipe, a blood collection tube, a blood return tube, a centrifugal tube, a plasma tube, an erythrocyte tube, a PRP tube, a blood platelet tube, a whole blood vessel and a mixing tube are distributed on the upper layer and the lower layer; and the outer periphery of the outer shell is provided with a plurality of connectors distributed in two layers, and the connectors communicate with corresponding pipelines arranged in the upper layer and the lower layer. According to the centrifugal bag type blood component separator, the structure is simple, only one double-layer flow path integration device is needed, the number of electromagnets needing to be used in cooperation with the whole device is small, the safety is high, the damage rate is low, and the service life is long.

Description

technical field

[0001] The invention relates to a centrifugal bag type blood component separator, which belongs to the field of devices for separating blood components. Background technique

[0002] At present, the widely used platelet collection device in domestic blood banks is the disposable centrifugal bag blood separator produced by Fresenius. This product is used in conjunction with the equipment. Relatively high, the consumption is increasing year by year, and the annual consumption is more than one million sets. The main part of this product is the monitoring box (such as Figure 15 and as Figure 16 ) and the centrifuge bag, and the structure of the monitoring box is complex, the working principle of the monitoring box is:

[0003] (1) The monitoring box is an integrated channel, the shell is made of plexiglass, and the upper cover is made of plexiglass. The shell and the upper cover are assembled by ultrasonic welding. The soft PVC diaphragm is also welded togeth...
