Sample analyzer and its detection process

Abstract

The invention discloses a sample analyzer and its detection process. The sample analyzer includes: an automatic sampling assembly, which transfers a test tube rack loaded with conventional test tubes to the center along the automatic sampling path in the X direction; manual sample injection Components, including the first test tube holder for placing the priority test tube, the first test tube holder moves between the initial position, the intermediate position and the manual placement position; the transfer assembly, including the second test tube holder for placing the test tube, the second The test tube holder moves between the transfer position and the sample suction position along the transfer path in the Y direction. The first test tube holder is biased to one side of the transfer path in the initial position; Sample collection; and a detection component, which detects the samples collected by the sampling component. The present invention receives the emergency test tube through the manual sampling component, and realizes the closed suction of the emergency sample in the machine, avoiding the risk of contamination of the emergency sample, and at the same time reducing The risk of medical staff being infected.

Description

technical field [0001] The invention relates to the technical field of sample analysis, in particular to a sample analyzer and a detection process thereof. Background technique [0002] The sample analyzer is the most commonly used blood cell analyzer, which uses reagents to perform statistical analysis on various cells in blood samples, such as red blood cells, white blood cells, platelets, hemoglobin, etc., to provide a basis for the diagnosis and treatment of diseases. [0003] With the increasing degree of automation of sample analyzers, more and more analyzers adopt the automatic batch injection mode. The user places multiple test tubes on the test tube rack, and the test tube rack transports the test tubes to the sample setting position of the analyzer in batches. , which can effectively reduce user operations and speed up detection. However, in the automatic batch injection mode, the sample tubes can only be tested one by one in sequence, which is not applicable to s...

AI Technical Summary

Problems solved by technology

However, in the automatic batch sampling mode, the sample tubes can only be tested one by one in order, which is not suitable for some emergency test tubes that need to be tested first. Therefore, some sample analyzers are also equipped with a manual sampling mode. The user can manually place the emergency test tube in the sample setting position

[0004] However, in actual operation, when placing the emergency test tube manually, the sample setting position is often occupied by the test tube being tested, and the user needs to wait for the entire detection process of the test tube to be completed before putting in the emergency test tube, which not only wastes time, but also increases emergency response time. Risk of tube contamination

In addition, the existing products also have open sampling, which requires the sampling needle to extend out of the casing, and the user manually places the emergency sample under the sampling needle for sampling, which not only increases the risk of accidental stabbing for medical staff, but also if the patient The samples carried the virus, which undoubtedly increased the risk of aerosol infection
