The present invention falls within the field of medical apparatuses. Disclosed are a method and a device for identifying platelet aggregation, and a flow cytometer, which are used for accurately giving an alarm about a platelet aggregation during blood cell analysis. The method comprises: detecting a pre-treated blood sample by using a flow cytometry technique so as to acquire scattered light signals and fluorescent light signals of the blood sample, wherein the scattered light signals are forward scattered light signals or side scattered light signals; differentiating between ghost particles and white blood cells by using a fluorescence-scattered light diagram generated by the scattered light signals and the fluorescent light signals of the blood sample; and counting a number of particles in a ghost characteristic region in the fluorescence-scattered light diagram of the blood sample and determining whether the number of particles exceeds a threshold value, and outputting a warning of platelet aggregation if the number of particles exceeds the threshold value.

Method and device for identifying platelet aggregation and cell analyzer

A cell analyzer and a sorting method for the cell analyzer are disclosed. Multiple optical signals generated by each of particles irradiated with light in a blood sample in a detection region are collected. The particles includes a first category of particles and a second category of particles. For each of the particles, Intensities of a first group of optical signals, which includes at least two optical signals selected from the multiple optical signals, and a pulse width of a second group of optical signals, which includes at least one optical signal selected from the multiple optical signals are acquired. For each of the particles, one or more reinforcement signals related to the particle are calculated based on an intensity of a first optical signal selected from the first group of optical signals and a pulse width of a second optical signal selected from the second group of optical signals, where the first optical signal is as same as or different from the second optical signal. The first category of particles and the second category of particles are distinguished from each other based at least partially on the one or more reinforcement signals related to each of the particles.

Cell analyzer and sorting method therefor

A cell analyzer and a particle sorting method and device are disclosed. The method comprises: acquiring a pulse width of at least one optical signal according to a detected optical signal, selecting at least one optical signal as a combined optical signal, and respectively calculating a signal intensity of the combined optical signal with the pulse width in a combinatorial way to obtain at least one reinforcement signal, where a difference between a first category of particles and a second categories of particles in the reinforcement signal is increased relative to a difference therebetween in the combined optical signal; and on the basis of the reinforcement signal and at least another signal, forming a new scatter diagram, where the at least another signal is one of other reinforcement signals and the optical signal, distinguishing the first category of particles from the second category of particles according to the new scatter diagram.
