Sample analysis system

The first imaging device in the sample analysis system takes an image of the blood sample container, and determines whether there is clot in the intermediate layer liquid, which solves the problem of premature coagulation and leakage detection in the prior art, and improves the accuracy of the blood sample measurement results.

AI Technical Summary

Technical Problem

It is difficult for the prior art to accurately determine whether there is clot in blood samples before aspiration, resulting in missed detection of premature coagulation, affecting the accuracy of blood sample measurement results.

Method used

A sample analysis system is adopted, which includes a sample storage device, a sample measuring device, a sample container transmission device, a first imaging device and a control device. The first imaging device photographs the sample container loaded with the blood sample, obtains an image of the junction liquid level or the junction liquid layer between the intermediate layer liquid and the upper layer liquid, and judges whether there are clots in the intermediate layer liquid and the degree to which the blood sample coagulates based on the image.

Benefits of technology

It improves the accuracy of judging whether a blood sample produces clots before aspiration, reduces the probability of premature coagulation and ensures the accuracy of blood sample measurement results.

Abstract

A sample analysis system (10), comprising a sample storage apparatus (100), a sample measurement apparatus (200), a sample container transfer apparatus (300), a first photographic apparatus (400) and a control apparatus (500). The control apparatus (500) is configured to obtain a first target image on the basis of an image captured by means of the first photographic apparatus (400) executing a first photographing action, and to output at least one of the following pieces of information: the first target image, a determination result for indicating whether there are clots in an intermediate layer liquid (32), and a determination result for indicating the degree of coagulation in a blood sample (30), wherein the first target image at least includes an image showing an interface liquid surface (321) or an interface liquid layer in a two-dimensional form and / or a three-dimensional form for use as a basis for determining whether there are clots in the intermediate layer liquid (32) and / or as a basis for determining the degree of coagulation in the blood sample (30). The probability of missed detection of early coagulation in the blood sample (30) is reduced, and the accuracy of determining whether clots have formed in the blood sample (30) before aspiration is improved.
