Strip screening mechanism for urine analyzer

Abstract

The invention discloses a strip screening mechanism for a urine analyzer. The strip screening mechanism comprises a strip screening rolling shaft, a stirring piece, a stirring motor, strip dischargingdetection sensors, a drying frame, a test strip storage bin, a test strip push plate, a limiting body, a support piece, side plates, a strip screening roller motor, a test strip reversing roller, a reversing roller motor and a test strip falling plate; the strip discharging detection sensors are arranged above the test strip falling plate, a strip screening groove is formed in the strip screeningrolling shaft in the direction of a rolling shaft, and an inclined angle is formed at the portion, the height of which is larger than the thickness of test strips, of the rear side of the strip screening groove; a strip arranging groove is further formed in the strip screening rolling shaft, the limiting body is fixedly provided with the stirring piece and the stirring motor, the stirring piece is fixed to an extension shaft of the stirring motor, and an opening groove providing convenience for the rotation of the stirring piece is formed in the portion, corresponding to the stirring piece, of the limiting body. By means of the strip screening mechanism, the speed of screening the test strips is increased, the damage, misjudgment and sticking problems in the process of screening the teststrips are solved, and the screening efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a strip selection mechanism for a urine analyzer. Background technique [0002] The strip selection mechanism of the current existing urine analyzer is driven by the strip selection roller motor 13 to rotate the strip selection rolling shaft 1, and the test strips 14 are individually selected through the strip selection groove 102 on the strip selection scroll shaft 1. The existing problems and shortcomings of this technology: 1. The test strip 14 is stuck during the screening process, and the screening speed is slow; 2. The screening damages the test strip greatly. The test strip 14 is easily damaged and warped by hard extrusion; three, the state of whether the test strip 14 has been screened out is not confirmed, and it is easy to misjudge and cause the test strip reversing roller 12 to be stuck, thereby causing serious mechanical problems. Fault; 4. The ...

The existing problems and shortcomings of this technology: 1. The test strip 14 is stuck during the screening process, and the screening speed is slow; 2. The screening damages the test strip 14 greatly. The test strip 14 is easily damaged and warped by hard extrusion; three, the state of whether the test strip 14 has been screened out is not confirmed, and it is easy to misjudge and cause the sticking of the test strip reversing roller 12, thereby causing serious mechanical damage. Fault; 4. The test strip 14 forms a struggle in the test strip storage compartment 6 (because the test strip is in a disordered state in the test strip compartment on a daily basis), even if the overall large reversal of the strip selection mechanism is controlled by the program or other measures, it still cannot Solve the problem that the test strip 14 cannot be screened for a long time
