Sample caching and handling system with emergency treatment and repetition measurement functions

Abstract

The invention discloses a sample caching and handling system with emergency treatment and repetition measurement functions. The sample caching and handling system with the emergency treatment and repetition measurement functions comprises a caching unit and a handling unit, wherein the caching unit comprises a caching area, a linking area and an emergency treatment area, wherein the emergency treatment area is provided with a sample frame emergency treatment tank; the handling unit comprises an X-axis installation plate; a first sliding block assembly is arranged on the X-axis installation plate; side plates are perpendicularly arranged on two sides of a Y-axis installation plate on the first sliding block assembly; two Y-axis guiding plates and a support plate on the top parts of the sideplates form a sample frame guiding tank for handling a sample frame; a second sliding block assembly is slidably arranged on the Y-axis installation plate; a pushing hand mechanism is arranged on thesecond sliding block assembly; a pushing hand of the pushing hand mechanism upwards extends out of the sample frame guiding tank. According to the sample caching and handling system with the emergency treatment and repetition measurement functions provided by the invention, the full-automatic sample feeding of an in vitro diagnosis analysis meter can be realized, the analysis meter can run efficiently, and the diagnosis efficiency is improved; the stability of samples during the handling process can be ensured, the cross contamination caused by liquid splashing is avoided, and the accuracy ofa sample result is ensured.

Description

technical field [0001] The invention relates to the field of in vitro diagnosis, in particular to a sample buffering and handling system with functions of emergency treatment and retesting. Background technique [0002] At present, there are two main sample transmission methods in automatic in vitro diagnostic analyzers (such as nucleic acid analyzers, automatic luminescence chemical immunoassay analyzers, etc.) and there are two types of sample tray injection and sample rack track injection. The sample can be transported to the right place by rotating the sample disc, which has a simple structure and low cost, so it is often used in low-end and mid-range models. However, the sample disk transmission method needs to place the sample before the test, and the sample cannot be placed or unloaded during the test, which cannot meet the continuous test requirements of the automatic in vitro diagnostic analyzer. In order to realize the continuous detection of samples, the existing...

Problems solved by technology

However, the above-mentioned technical solution has the following problems: First, the length of the support frame is long and takes up a large space, which increases the processing difficulty of the sample temporary storage bin. At the same time, there is a risk of motion interference between the support frame and the temporary storage bin; The stability is poor, and there is liquid splashing, which will cause cross-contamination and seriously affect the accuracy of the sample test results; the support frame is easy to swing during the transportation process, and when the support frame pushes the sample rack into the temporary storage bin, it is prone to jamming, increasing Second, the guiding effect of the temporary storage chamber is poor, and there is a risk of collision when the sample rack enters the temporary storage chamber, which requires high control precision of the drive motor; moreover, the cam follower moves along the arc-shaped cam groove to drive The support frame goes up and down, once the motor fails, the cam follower will be stuck in the cam groove, and the service life of the cam follower and the cam will be short
