Abstract

The invention belongs to the field of devices for blood component separation, and relates to a double-layer-flow path integration device for a centrifugal bag type blood component separator. The integration device comprises an upper cover plate, a middle integration body and a lower cover plate from top to bottom, the middle integration body comprises an outer shell, the interior of the outer shell is partitioned into an upper layer and a lower layer by a middle partition plate, anticoagulant pipes, a brine pipe, a blood collection pipe, a blood return pipe, centrifugal pipes, plasma pipes, erythrocyte pipes, PRP pipes, blood platelet pipes, a whole blood pipe and mixing pipes are distributed on the upper layer and the lower layer, a plurality of connectors distributed in a two-layer mode are arranged on the periphery of the outer shell, and the connectors communicate with corresponding pipelines arranged in the upper layer and the lower layer. The integration device has the advantages that the structural design is reasonable, the pipeline structure is simple, in actual use, the number of parts which are required to be matched with the device for use is few, the safety is high, the damage rate is low, and the service life is long; and in the circulation process of blood, air is not prone to mixture, so that the damage probability of a blood donor is reduced.

Description

Technical field

[0001] The invention relates to a double-layer flow path integrated device for a centrifugal bag type blood component separator, which belongs to the field of devices for blood component separation. Background technique

[0002] At present, the most widely used platelet collection instrument in domestic blood stations is the disposable centrifugal bag blood separator produced by Fresenius. This product is used in conjunction with the equipment. Since it entered China in 2006, due to the collection efficiency and purity Relatively high, the usage is increasing year by year, and the annual usage is more than one million sets. The main component of the product is the monitoring box (such as Figure 14 And as Figure 15 ) And the centrifuge bag, and its monitoring box structure 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, the upper cover is made of plexiglass, the s...
