Description

Technical Field

[0001] The embodiments of the utility model belong to the technical field of blood preparation, and more specifically, relate to a pump-in type blood bag transfer and filling device. Background Art

[0002] Blood has various specifications, and is usually prepared into blood products of the same specifications according to the specifications of the collected blood. However, for patients such as infants and children who have a small amount of single blood transfusion, even if the smallest specification of blood is used, it is still excessive, which can easily cause blood waste and increase the economic burden on patients. Therefore, for this type of patient group, there has always been a demand for the use of small-specification blood. Since whole blood collection does not have small specifications, it is necessary to use conventional specifications of blood products by weight and divide them equally by transferring bags, but there is currently no dedicated blood component packaging equipment. Therefore, a small-specification blood packaging auxiliary equipment is proposed, which is of great significance for improving the workflow and standardizing the preparation of small-specification blood, as well as maximizing the optimization of blood resources.

[0003] In order to solve the above technical problems, the conventional operation method currently relies on manual operation by staff. The specific operation requires manual mixing and squeezing of blood from the mother bag into the connecting bag, repeated weighing to make the weight of each bag of blood equal, and then disconnecting by heat sealing to achieve the requirement of equal division.

[0004] Although the above method realizes the packaging operation, the following technical problems still exist: (1) Manual operation is difficult to standardize, and because the blood bag has a long blood braid, the weighing process is inaccurate, which increases the distribution error and the quality uniformity of the obtained blood product is poor; (2) Automated equipment is not widely used, and manual operation not only increases the workload, but also lacks efficiency; (3) The existing technology fails to realize the automated operation of precise packaging, automatic heat sealing, and disconnection processes in one machine, so it is possible to consider integrating multi-process auxiliary functions to achieve a significant improvement in work efficiency.
