A cell suspension dispensing device

Abstract

The present invention relates to the technical field of cell suspension, in particular to a cell suspension dispensing device, including a detection mechanism and a support mechanism; the detection mechanism includes a light source capable of emitting light without damaging cells and a photosensitive detection element for receiving the detection light source , one side of the housing is also connected to an operation console, and an indicator light for indicating whether the transparent dispensing tube package is qualified is installed side by side on the upper part of one side of the housing, and the indicator light is controlled by the operation console and It can change the color of red and green to indicate whether the cell suspension after subpackaging is qualified or not; the present invention shortens the subpackaging time and reduces the contact time between the inside of the sample and the air by using the batch detection method of the subpackaging and testing mechanism of the subpackaging plate , and easy to operate; it can accurately exclude unqualified samples, change the error of traditional color judgment directly by naked eyes, reduce the discarding rate of qualified products, prevent unqualified products from occupying resources for cryopreservation, and improve efficiency.

Description

technical field [0001] The invention relates to the technical field of cell suspension, more specifically, it relates to a cell suspension dispensing device. Background technique [0002] Red blood cell suspension, also known as suspended red blood cells, referred to as red suspension, is prepared by collecting whole blood in a triple bag, removing most of the plasma by centrifugation, and adding red blood cell preservation solution. The storage period of suspended erythrocytes varies with the added preservation solution, and generally can be stored for 35 days at 2-6°C. Suspended red blood cells can reduce plasma-induced side effects because most of the plasma is removed. Due to the addition of the preservation solution, not only can the red blood cells be better preserved, but also has a dilution effect, making the infusion smoother. Patients with chronic anemia can be transfused with suspended red blood cells in order to improve the symptoms directly caused by hypoxia w...

Problems solved by technology

[0003] The cell suspension needs to be subpackaged and stored, and during the process of cell suspension subpackaged and stored, due to contact with air or other reasons, it is inevitable that the sample of the cell suspension subpackaged will be unqualified; When subpackaging, the operator often discards the lighter-colored samples and debugs the darker-colored samples through comparison with the naked eye after subpackaging. It is impossible to accurately obtain more information, and the debugging takes a long time

Moreover, due to the limitation of the naked eye during the comparison process, it is easy to cause qualified samples to be discarded and unqualified samples to occupy storage space.

[0004] For example, the patent application number CN201920369072.1 and the authorized patent application number CN201920024745.X do not disclose how to deal with the samples after subpackaging. General operators can only slightly adjust the darker color in the later stage of subpackaging. Discard samples with lighter colors, resulting in a waste of resources and a long time-consuming operation
