Sample analyzer and its sample testing process

Abstract

The invention discloses a sample analyzer and a sample detection process thereof. The sample analyzer comprises: an automatic sample injection component, which automatically transports a sample tube toward a first sampling position along an automatic sample injection path in the X direction; an emergency sample injection component, along the X direction The manual sampling path in the X direction transports the emergency sample tube between the manual sample setting position outside the machine and the second sampling position inside the machine; the transport assembly, the transport path in the Y direction transports the sample between the receiving position and the sampling position The tube, the second sampling bit, the receiving bit and the sampling bit are sequentially arranged along the Y direction; the scheduling component includes a first path in the Y direction and a second path in the X direction, and the first path is provided with a first grab bit and a first Two grasping positions, the first grasping position is directly above the second sampling position, and the second grasping position is directly above the receiving position; and the sampling assembly, for sampling the sample tube in the sampling position, the present invention can activate the emergency at any time In detection mode, users do not need to wait, avoiding the risk of 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 sample 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, more and more analyzers adopt the automatic batch injection mode. The user places the test tubes on the tube rack, and the tube rack transports the test tubes to the sample port of the analyzer in batches. The sample port grabs the test tube for sampling and detection, which can effectively reduce the user's operation and speed up the detection speed. However, in the automatic batch injection mode, the test tubes can only be tested one by one in se...

Problems solved by technology

However, in the automatic batch sampling mode, the test tubes can only be tested one by one in order, which is not applicable to the emergency test tubes that need to be tested first

[0004] For this reason, some analyzers are also equipped with an open sampling mode. When there is a detection demand for emergency test tubes, the sampling needle protrudes out of the casing, and the user directly places the emergency test tube under the sampling needle for sampling, but this increases medical care. Risk of accidental stab wounds and increased risk of aerosol infection if patient samples carry the virus
