Abstract
Disclosed in the present invention is a blood sample analyzer, including a sample conveying device, a first agitating device, a second agitating device and a controller, etc. When the first agitating device drives a sample container placed in a sample container accommodating hole to agitate a blood sample, a bottom of the sample container is kept lower than an opening of the sample container. In addition, the present invention further discloses a blood sample agitating device, a blood sample analysis method, a blood sample agitating method, and a computer storage medium.
Claims18
A blood sample analyzer, comprising:
- a sample conveying device for conveying a sample rack loaded with a first sample container and/or a second sample container;
- a carrying device, wherein when the sample conveying device conveys the sample rack to a predetermined position, the carrying device is configured to carry the first sample container on the sample rack from the predetermined position to an accommodating hole of a first agitating device;
- the first agitating device having the accommodating hole for placing the first sample container, the first agitating device being capable of driving the first sample container containing a small-volume blood sample and placed in the accommodating hole to agitate the small-volume blood sample;
- a second agitating device capable of picking up the sample rack or the second sample container on the sample rack, and driving the second sample container containing a common-volume blood sample to agitate the common-volume blood sample;
- and
- a controller configured to communicate with the sample conveying device, the first agitating device and the second agitating device, and control the sample conveying device, the first agitating device and the second agitating device;
- wherein when the first agitating device drives the first sample container placed in the accommodating hole to agitate the small-volume blood sample, a bottom of the first sample container is kept lower than an opening of the first sample container,
- wherein the first agitating device further comprises:
- an accommodating seat, a top part of which is provided with the accommodating hole;
- and
- a driving device for driving the accommodating seat to rotate, thereby driving the first sample container in the accommodating hole to rotate, so as to agitate the small-volume blood sample,
- wherein the accommodating hole is arranged eccentrically relative to the accommodating seat, so that the first sample container in the accommodating hole is capable of being rotated eccentrically.
9 more elements
A blood sample analysis method, comprising:
- providing a blood sample analyzer including a first agitating device, a second agitating device, an aspirator, a tester and a controller;
- the method further comprises:
- measurement mode determination step:
- determining whether a current measurement mode is a first measurement mode or a second measurement mode by the controller;
- first test sample preparation step:
- when the current measurement mode is determined to be the first measurement mode, agitating a blood sample in a sample container by the first agitating device, and aspirating, by the aspirator, a first sampling amount of the agitated blood sample to prepare a first test sample;
- second test sample preparation step:
- when the current measurement mode is determined to be the second measurement mode, agitating the blood sample in the sample container by the second agitating device, and aspirating, by the aspirator, a second sampling amount of the agitated blood sample to prepare a second test sample;
- and
- test step:
- testing the first test sample or the second test sample by the tester;
- wherein, while the blood sample is agitated, a sampling needle does not touch the blood sample in the sample container,
- wherein the first agitating device comprises:
- an accommodating hole for placing the sample container:
- an accommodating seat, a top part of which is provided with the accommodating hole;
- and
- a driving device for driving the accommodating seat to rotate, thereby driving the sample container in the accommodating hole to rotate,
- wherein the accommodating hole is arranged eccentrically relative to the accommodating seat, so that the sample container in the accommodating hole is capable of being rotated eccentrically.
