Micro-column gel card puncture device and full-automatic blood type analyzer

Abstract

The microcolumn gel card puncturing device comprises a driving mechanism, a mounting plate, a gear assembly, a guide rail assembly and a puncturing mechanism, the driving mechanism comprises a first motor and a second motor, and output shafts of the first motor and the second motor penetrate through the mounting plate and the gear assembly correspondingly; comprising a first gear arranged on an output shaft of a first motor, a second gear arranged on an output shaft of a second motor, a guide rail assembly, a first guide rail, a second guide rail, a third guide rail, sliding blocks arranged on the guide rails in a sleeving mode, a puncturing mechanism, a first puncturing base, a second puncturing base and a third puncturing base, and the puncturing mechanism is fixedly connected with the sliding blocks on the guide rails. The puncture mechanism can move up and down along the guide rail, and a rack matched with the gear assembly is arranged on the side face of the puncture mechanism. The micro-column gel card puncture device can respectively complete puncture actions of three groups of samples of a nine-hole-site micro-column gel card, is high in puncture efficiency, high in accuracy, good in stability and small in occupied space, and well meets clinical detection requirements.

Description

technical field [0001] The invention relates to the field of in vitro diagnostic medical devices, in particular to a microcolumn gel card puncture device and an automatic blood type analyzer. Background technique [0002] The automatic blood type analyzer is based on micro-column gel technology, which can be used for ABO positive and negative typing, Rh antigen detection, irregular antibody screening and cross-matching blood tests, etc. The automatic blood type analyzer is mainly composed of a sample adding module, a mechanical gripper module, a centrifuge module, a test tube rack scanning module, a puncture module and an interpretation module, etc., which can automatically complete the sample distribution, barcode reading, sample addition, reagent Mix, incubate, puncture, centrifuge, read and analyze until the transmission of printed results. [0003] The micro-column gel card is generally sealed by aluminum foil. When testing, it is necessary to puncture the sealed alumin...

AI Technical Summary

Problems solved by technology

[0004] In this technical field, three groups of motors are generally used to control the puncture of three groups of holes respectively, but this method increases the occupied space of the puncture mechanism and the cost is relatively high

In the CN204086285U utility model patent previously applied by the applicant, the eccentric wheel mechanism is adopted, but the eccentric wheel is easy to slip during the puncturing movement, resulting in low stability of the puncturing device
