Sample analyzer and its manual injection method

Abstract

The invention discloses a sample analyzer and a manual sample injection method thereof. The sample analyzer comprises: an automatic sample introduction component, which automatically transports a tube to be tested to a grasping position along the automatic sample introduction path in the X direction; the manual sample introduction component , including the priority sample holder. The priority sample holder includes two test tube holes. When in the storage state, the center line of the two test tube holes extends along the X direction; in the open state, the center of the two test tube holes is connected. The line extends along the Y direction; the sample setting seat moves between the exposed position and the transfer position along the manual injection path, the exposed position is outside the casing, and the transfer position is above the grab position; when the automatic sample injection module is working, the sample setting is given priority. The seat is in the storage state; when the manual injection assembly is working, the priority sample seat is switched to the open state and moves along the manual injection path, and the manually placed test tube is received in the exposed position and transported to the transfer position. The user can start the manual operation at any time. The injection component is used for emergency injection to avoid contamination of emergency samples.

Description

technical field [0001] The invention relates to the technical field of sample detection, in particular to a sample analyzer and a manual sample injection method 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, more and more analyzers adopt the automatic batch injection mode. The user places the 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. The sample position grabs the test tube for detection, which can effectively reduce the user's operation and speed up the detection speed. However, in the automatic batch sampling mode, the sample tubes can only be tes...

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 tubes that need to be treated first. Therefore, some analyzers are also equipped with a manual sampling mode. The test tube is manually placed in the sample setting position

[0004] However, in actual operation, when placing the emergency test tube manually, the test tube holder 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 RISK OF CONTAMINATION OF ED SAMPLES
