Automatic urine analyzer test strip screening mechanism

Abstract

A full-automatic urine analyzer test paper strip screening mechanism comprises a support main body, a test paper cylinder mechanism, a sorting mechanism, an overturning mechanism, a first-stage cabinopening mechanism and a second-stage cabin opening mechanism, wherein the test paper cylinder mechanism, the sorting mechanism, the overturning mechanism, the first-stage cabin opening mechanism and the second-stage cabin opening mechanism are fixed to the support main body. According to the full-automatic urine analyzer test paper strip screening mechanism, test paper sorting work is divided intothe two parts of sorting and overturning and two working mechanisms capable of independently and parallelly operating are arranged, each mechanism is provided with an independent test paper storage cabin, and a second-stage storage cabin of the overturning mechanism achieves a crucial buffering effect. The first step is that test paper is divided into single strips, and division is completed by the sorting mechanism; and the second step is that the test paper with the reagent surface facing down is overturned, and overturning is completed by the overturning mechanism. A test paper overturningmode is changed from the high-risk mode that originally the test paper penetrates through from the interior of an overturning shaft square hole (sudden seam) into the mode that the test paper reliably and safely falls into a roller groove to rotate forwards and backwards to determine the test paper direction. The full-automatic urine analyzer test paper strip screening mechanism is not liable toclamp paper and the sorting speed is high.

Description

technical field [0001] The invention relates to medical equipment, in particular to a screening mechanism for test strips of a fully automatic urine analyzer. Background technique [0002] The automatic urine analyzer adopts the classic multi-wavelength reflectance detection principle to test 10-12 components of urine. The automatic urine analyzer is easy to operate. The user only needs to put the test tube containing the sample into the special test tube rack, and the test result can be obtained in one minute. It is suitable for unattended continuous testing of batch samples. [0003] The structure of a fully automatic urine analyzer generally includes a test strip screening mechanism, a test strip conveying mechanism, a titration system mechanism, a detection and analysis mechanism, and a test tube transmission mechanism. Among them, the test strip screening mechanism will put the batch of test strips in the instrument, and sort any one of them into the subsequent detecti...

AI Technical Summary

Problems solved by technology

In the existing automatic urine analyzer, when the test paper slides along the guide strips, once the friction force between the guide strips is inconsistent and the test paper tilts, the test paper cannot be fully adjusted to the guide shaft, and paper jams will inevitably occur when the guide shaft turns over.

After the automatic urine analyzer has been used for a period of time, the test paper powder and dust accumulated during the sorting process will naturally cause the friction between the guide plates to be inconsistent, and the weight of the test paper itself will not be balanced. will appear from time to time

In addition, the existing test strip screening mechanism has a slow sorting speed and cannot adapt to the current testing volume of large hospitals
