Container Handling Systems, Container Rotation Handling Systems, and Sample Analyzers

Abstract

The invention discloses a container treatment system, a container rotating treatment system and a sample analyzer. The container treatment system comprises a sample suction device, a container seat, acontainer catching device, an information reading device, a container locating module, and a limiting plate for limiting separation of a container from the container seat, wherein the limiting plateis movably arranged on a substrate; when moving to a preset position, the limiting plate relieves limitation to the container; the container treatment system further comprises a rotating device for driving the container to rotate and the container seat for placing the container; the bottom of the container seat is connected with a negative pressure source for supplying negative pressure to the container; information reading and sample suction are both integrated at the same position; furthermore, in an information reading process, in order to guarantee successful rotation of the container, thenegative pressure source is added, so that the container can rotate in the container seat more stably; meanwhile, by the arrangement of the limiting plate, a catching module can catch and release thecontainer.

Description

technical field [0001] The invention relates to the technical field of in vitro diagnosis, and more specifically relates to a container processing system, a container rotating processing system and a sample analyzer. Background technique [0002] Blood count is one of the most common blood tests performed in medicine. Because the cells (such as white blood cells, red blood cells, and platelets) circulating in the human bloodstream can provide an overview of the patient's overall health, medical professionals Certain disease states can be identified based on the increase or decrease of a particular type of cell in the bloodstream. Initially, medical professionals counted blood cells by hand: observing a blood smear (also known as a blood film or peripheral blood smear) made of a patient's blood sample under a microscope. With the development of technology, now This process is usually done with the help of a hematology analyzer (also known as: blood cell analyzer). [0003] ...

Problems solved by technology

[0007] When injecting samples into the conventional containers of the hemocytometer, the information input operation is usually performed on the container rack, but for the priority processing containers, the information input is performed on the container holder. Station and the sample suction station move back and forth, the priority is to process the container between the sample setting station and the sample suction station for information input operations. During the information input process, the container needs to be clamped, positioned and rotated; In the sample suction station, the container is usually punctured and sampled. During the puncture sampling process, the container needs to be positioned. In the previous technical solution, the sample suction station needs to be positioned, and in the process of information input Positioning is also required, so it is necessary to repeatedly set two parts that can hold the test tube, resulting in a complicated structure
