Description

Technical Field

[0001] The embodiments of the utility model belong to the technical field of blood centrifugal mass balancing, and more specifically, relate to a stepped blood mass balancing device. Background Art

[0002] The blood collected by blood stations plays an indispensable and important role in medical treatment. With the development of the transfusion medicine industry, the whole blood collected from blood donors needs to be separated and prepared into different blood products according to the characteristics of various blood components. Centrifugation is a necessary step before separation and preparation. According to the difference in the specific gravity of red blood cells and plasma, they are centrifuged in a large-capacity low-temperature centrifuge to separate the two layers, and then separated and prepared with the help of corresponding equipment. The centrifugation effect of blood is an important factor in determining the separation quality. In addition to the performance of the centrifuge, the balance is very important. Unbalanced centrifugation is not only difficult to achieve the ideal centrifugation effect, but also easy to cause damage to the centrifuge. The centrifugation process needs to withstand a centrifugal force of about 4600G. Usually, the weight of a single centrifuge cup containing blood is about 1500g, and the balance error needs to be controlled within the range of ±5g.

[0003] There are dedicated blood balancers on the market. Although they can meet basic work needs, they still have the following technical problems: (1) The balancing reminder function is not convenient. Specifically, the front and rear rows of holes on the balancer are on the same plane. After the centrifuge cups are placed in each hole, the light is blocked, making it difficult to observe the light reminder function; the weight display panel is separated from the holes and cannot be effectively matched intuitively; (2) When the weight of a pair of centrifuge cups is unbalanced, a certain weight of balancing bar needs to be manually added to balance the weight. The process of adding requires continuous calculation of the weight and re-weighing and comparison, which is inefficient.

[0004] Therefore, designing an intelligent blood balancer that is easy to observe and operate and can automatically adjust the weight to achieve automatic balancing will help improve the convenience of operation and improve work efficiency. Utility Model Content
