Analysis device and method for cell count in the analysis device

Abstract

It is possible to optimally control window movement by storing in a window memory the information indicating that movement has been performed by a distance in accordance with the window size, thereby preventing duplicate detection of the same cell. There is no need of acquiring data each time the window size is modified. Thus, it is possible to provide a cell analysis device capable of obtaining a desired number of cells by one data acquisition and performing a highly-accurate analysis in a short time.

Description

technical field [0001] The present invention also belongs to the technique of analyzing cells in the field of medical equipment, and relates to an analysis device and a cell counting method in the analysis device. It injects samples containing cells of various sizes on a disk, and irradiates the disk with light. According to its light reflection or transmission light, the cells in the test are discriminated and counted according to the cell size. Background technique [0002] In the field of medical equipment, as the prior art 1 of an analysis device for discriminating and counting cells in a sample, an analysis device using an optical disc is used. In this analysis device, the light source tracks the position of the disc. On the track, light is irradiated on a sample injected into the disk, and the detector detects its reflected light or transmitted light. The detected signal passes through the AD converter and is stored in the buffer memory. There is a calibration mark i...

Problems solved by technology

However, the problem with that is that it not only doubles the analysis time, but also expands the analysis error due to the different analysis conditions.

[0022] Therefore, in the conventional cell counting method, by converting "1" into "0" for the part detected and once counted by the window, it cannot be repeatedly read as "1". However, when switching the size of the window When performing detection, it is necessary to perform window scanning on all rows again to re-determine whether there are cells on the track. The problem is that the measurement takes more time

[0023] In addition, in the method of prior art 3, since the window 314 with a fixed size for the target cell is used, the memory is rewritten to "0" every time a cell is detected, so for a cell with a large size, as Figure 18 As shown, the window size must be changed to window 315. At this time, because the memory cannot be reused, it is necessary to resample

Therefore, there is a problem that due to different measurement conditions, the counting error may be enlarged, and it will take more measurement time.
