Embodiment Construction

[0045] The present invention will be described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can accurately understand the technical solution of the present invention.

[0046] Words such as first and second described herein are used to distinguish two or more components of the same or similar structure, or two or more structures of the same or similar structure, and do not represent a special limitation on the order.

[0047]The orientation in this article is defined with reference to the anti-collision cleaning device of the cuvette in use. The cuvettes required for in vitro diagnosis are usually carried on the reaction plate. The reaction plate is usually in the shape of a disc. The circumferential interval arrangement; the anti-collision cleaning device described in this paper is fixedly connected to the top of the reaction plate and is in the position corresponding to the reaction cup. To be precise, one cleaning needle or ...

Abstract

The invention provides an anti-collision cleaning device of a reaction cup. The device has the advantages that the structure is simple, the sensitivity is high, and the anti-collision reliability is improved. The anti-collision cleaning device comprises a mounting plate connected with a driving mechanism, two or more than two cleaning needles and at least one drying needle are arranged on the mounting plate, the cleaning needles and the drying needle are distributed alternatively in the arrangement direction of the reaction cup, the anti-collision cleaning device further comprises an inductionpiece used for indicating collision risk of the cleaning needles, the cleaning needles are fixed on the mounting plate, the drying needle is provided with a degree of freedom moving up and down relative to the mounting plate, and the tail end of the drying needle is lower than the tail ends of the cleaning needles by a first preset distance. According to the device, in the process of the mountingplate driving the cleaning needles and the drying needle to move downwards, the tail end of the drying needle is blocked to move upwards relative to the mounting plate, the when the moving amount exceeds a first preset safety distance, the induction piece is triggered, and the first preset safety distance is smaller than or equal to the first preset distance.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-collision cleaning device for cuvettes. Background technique [0002] In vitro diagnosis, namely IVD (In Vitro Diagnosis), refers to products and services that obtain clinical diagnostic information by testing human samples (blood, body fluids, tissues, etc.) outside the human body, and then determine diseases or body functions. One of the most commonly used diagnostic methods in the medical field. Cuvettes are the most frequently used containers for in vitro diagnostics. [0003] If the inner wall of the cuvette is not cleaned cleanly, it will cause cross-contamination of the sample and affect the accuracy of the test results. If the mechanism fails or is improperly operated, the cleaning needle will stick to the edge of the cuvette; if the mechanism does not stop the downward movement after the cleaning needle touches the bottom of the cuvette, the cleaning ne...
