Embodiment 1

[0028] Please refer to figure 2 This embodiment provides a blood tester, which includes a sample feeding module 10, a measurement module 30, a sample collection and distribution module 20, a liquid path support module, and a control module.

[0029] The sample feeding module 10 is used for loading samples to be tested.

[0030] There are a plurality of measuring modules 30, and each measuring module 30 is used to measure the dispensed liquid sample for the purpose of obtaining different parameters. In specific embodiments, such as figure 2 As shown, the measurement module 30 may include a WBC classification measurement module 301, a CRP measurement module 302, and a blood routine count measurement module 303. The liquid sample may be a whole blood sample.

[0031] The sample collection and distribution module 20 is used to collect samples and distribute the collected samples to each measurement module 30.

[0032] The liquid path support module (not shown in the figure) provides li...

Embodiment 2

[0053] Based on the blood tester provided in the first embodiment above, this embodiment correspondingly provides a sample collection and distribution method of the blood tester, including: the sample collection and distribution module of the blood tester collects the sample to be tested once, and then collects the sample The samples are allocated to each measurement module in a predetermined order.

[0054] Preferably, the sample collection and distribution module distributes the sample to the measurement module, specifically: the sample collection and distribution module first extends the needle hole of the sampling needle under the liquid level of the bottom liquid of the measurement module, and then injects the sample into the measurement module. The bottom liquid in the measurement module can be a hemolytic agent.

[0055] After the sample collection and distribution module performs one sample collection, it needs to continuously perform quantitative distribution among multipl...

Abstract

A sample analyzer and a sample collection and distribution method thereof are provided. A sample collection and distribution module conducts a first collection on a sample to be tested; and then the collected sample is assigned to a plurality of measurement modules according to a predetermined sequence. Compared to a way of multiple sample collection and multiple sample distribution, the method provided by the invention simplifies the steps of sample collection and distribution, improves the test efficiency of liquid samples, and avoids the risk of sample contamination caused by a plurality of sample collections.

Description

Technical field [0001] This application relates to the field of liquid sample detection, in particular to a sample analyzer and a sample collection and distribution method. Background technique [0002] In clinical practice, it is often necessary to use a blood sample to detect various hematology parameters, such as blood routine parameters and CRP (C-Reactive Protein, C-reactive protein) parameters. [0003] On the one hand, because blood cell count, classification and CRP detection are performed on different blood analysis instruments using different types of samples. Therefore, it is common to use whole blood samples for blood cell count and classification on a blood cell analyzer, and use serum to measure CRP on a biochemical analysis or special protein analyzer. However, blood routine parameters and CRP are often used in combination in clinical practice. Medical staff need to collect two samples from patients and test them on different machines. For patients, the pain caused...
