Embodiments of this application provide a code scanning method and an electronic device. The method is applicable to the electronic device. The electronic device includes a camera. The method includes: The electronic device displays a code scanning interface, and then obtains an identification frame image and a preview frame image, where the identification frame image and the preview frame image are obtained by processing a code scanning image collected by the camera. The electronic device displays the preview frame image in the code scanning interface. The electronic device conducts, in a case that ambient light brightness of the identification frame image is greater than or equal to a threshold, code scanning identification on the identification frame image, and determines a code scanning identification result. According to the method, an invalid identification frame image is deleted, to improve code scanning efficiency.

Code scanning method and electronic device

A smear staining machine and a smearing control method and device thereof. The viscosity of the test sample is used for guiding the configuration of at least on smearing parameter. Since the viscosity of the test sample presents multiple influences of many effecting parameters, it is more suitable for presenting the characteristics of the test sample. Therefore, better smearing effect could be acquired by referring the viscosity of the test sample to get the smearing parameter.

Smear staining machine

The present disclosure provides a particle analyzer and a particle test control method and device thereof. A method comprises, acquiring a blood sample in a test location; preparing a diluted sample by the acquired sample; after acquiring a diluted sample, monitoring whether a pore blocking event occurs during a counting process; when the pore blocking event occurs, suspending the test of the sample, and performing an unblocking operation; and after the unblocking operation is completed, re-counting the same diluted sample without re-acquiring and re-diluting the blood sample by the impedance method after the unblocking operation.

Particle analyzers and particle test control methods and devices thereof

A method and particle analyzer for measuring a low concentration particles sample disclosed.

Method and particle analyzer for measuring a low concentration particle sample

The present disclosure provides a particle analyzer and a particle test control method and device thereof. A method comprises, after acquiring a diluted sample, preserving a part of the diluted sample, and monitoring whether a pore blocking event occurs during a counting process; when the pore blocking event occurs, suspending the test of the sample, and performing an unblocking operation; and after the unblocking operation is completed, controlling a liquid addition system to again acquire the preserved part of the sample from a reaction cell or a tube of the liquid addition system and inject it into a counting cell, and then re-counting the sample in the counting cell by an impedance method. The method makes full use of the residual diluted sample for a second test to eliminate the impact of pore blocking that occurs in the first measurement of the sample on the test result, and there is no need to be place the sample tube again at test position for re-acquisition and re-dilution, thereby reducing the probability of pore blocking.

A smear staining machine and a smearing control method and device thereof. The viscosity of the test sample is used for guiding the configuration of at least one smearing parameter. Because the viscosity of the test sample presents multiple influences of many effecting parameters, it is more suitable for presenting the characteristics of the test sample. Therefore, a better smearing effect could be acquired by referring the viscosity of the test sample to get the smearing parameter.
