Problems solved by technology

For example, when measuring platelets, the above-mentioned side lobes will be divided into platelet cells, resulting in high platelet measurement values ​​by optical methods
[0004] This problem can fundamentally remove sidelobe interference by changing optical devices, but the requirements for optical components are high, which will increase the cost; linear correction can also be used to compensate for the misidentification of high and low value samples and the number of missed identification cells. This method is relatively simple, but it does not solve the problem from the source, but only adjusts the final value, so the measured value is not accurate enough, and the measured value of some samples may appear obviously abnormal

Abstract

The invention provides a pulse recognition method and device, a storage medium, equipment and a blood cell analyzer. The pulse identification method comprises the following steps: acquiring a detection signal in a forward scattering direction and preliminarily identifying a pulse; determining whether there is a sidelobe pulse in the adjacent pulses based on whether the peak value time difference of the adjacent pulses, the amplitude difference between the peak value of the previous pulse and the end point or the amplitude difference between the peak value of the current pulse and the starting point, and the amplitude of the end point of the previous pulse satisfy a first preset condition; under the condition that the sidelobe pulses exist in the adjacent pulses, the sidelobe pulses are removed from the preliminarily recognized pulses, and a first pulse sequence is obtained. According to the invention, the influence of optical sidelobe on platelet counting can be removed from the pulse identification stage, and the cost does not need to be increased.

Description

technical field [0001] The present invention relates to the technical field of blood cell detection, in particular to a pulse identification method, device, storage medium, equipment and blood cell analyzer. Background technique [0002] There are two main methods for blood cell detection in the blood cell analyzer: one is the impedance method, and the other is the optical method. Most of the early blood analyzers used the impedance method to measure blood cells. The specific principle of the impedance method is Coulter's principle, which uses the change of impedance at both ends of the small hole when blood cells flow through the small hole for detection. With the advancement of cell detection technology, the optical method has emerged. Realize the detection of blood cells. Compared with the traditional impedance method, the optical method is more sensitive in detecting blood cells, less affected by the blood sample, and more accurate. Therefore, high-end blood cell anal...
