Abstract
The utility model discloses a test tube bar code reader of a blood cell analyzer, comprising an installation support. The installation support is provided with a test tube rotating mechanism, an elevating and limiting mechanism and a bar code reader. With the cooperation among the abovementioned mechanisms, rotation of a test tube in a test tube support is realized, and thus the bar code reader is facilitated to read bar code information on the test tube reliably. As a result, an operator can rotate the test tube in the test tube support at will without considering the orientation of the bar code when using the blood cell analyzer, thereby greatly raising usage convenience for the operator. In addition, even phenomena that the bar code is pasted slantly, the test tube rotates in the test tube support during the conveying process, etc., occur, the bar code reader can read the bar code information on the test tube reliably because the test tube can rotate in the test tube support.
Description
Technical field
The utility model relates to cellanalyzer, is specifically related to the test tube apparatus for reading of bar code of cellanalyzer.
Background technology
In the medical institutions of hospital's one class, the blood that gathers from the experimenter is contained in vitro, related tests person's personal data comprise that name, sex and age etc. are printed on the bar coded sticker with the form of bar code, bar coded sticker then is attached on the test tube that the blood that gathers from the experimenter is housed, and these test tubes with bar coded sticker are sent to the detection of carrying out relevant item in the control laboratory.
Cellanalyzer need to read the bar code information on the test tube equally when detecting.Existing cellanalyzer is when detecting, being used for placing the test tube that blood sample is housed that posts bar coded sticker is in the test tube flat that is placed on the test tube rack, one longitudinal grooved (being that bar code reads window) all arranged on each test tube flat on the test tube rack, this fluting is right against the induction window of barcode reader, at this moment, only have when the bar coded sticker on the test tube just is being revealed in longitudinal grooved on the test tube flat, barcode reader could read bar code reliably.Therefore, operating personnel when holding test tubes, must be noted that bar code on the test tube towards, otherwise then read less than bar code information, this has increased operating personnel's workload undoubtedly.In addition, if bar coded sticker phenomenon bar such as run-off the straight when pasting on the test tube, if the longitudinal grooved that the bar code on this moment test tube just in time is revealed on the test tube flat also might read less than bar code information; Moreover, even being about to bar coded sticker when holding test tubes is positioned on the longitudinal grooved on the test tube flat, because the test tube in the test tube rack may rotate in course of conveying, thereby make the longitudinal grooved on the bar coded sticker skew test tube flat, therefore the same situation about reading less than bar code information that exists.
For overcoming defects, also have in the prior art test tube is taken out from test tube rack, before the scanning reader, rotate to an angle and read the apparatus for reading of bar code of bar code information, be the utility model patent of CN1667419 such as publication number, disclose and a kind ofly had the bar-code reading device of test tube from the mechanism that support pulls up, have container, support and barcode reader, container has an outer peripheral face that bar code is set on it; Support remains on stand up position with described container, and barcode reader reads bar code from container; This reading device comprises that also one pulls up mechanism, and when barcode reader read described bar code, the described mechanism that pulls up pulled up container from support, until bar code exposes fully.But the apparatus for reading of bar code structure of this structure is comparatively complicated, has the many hidden danger in trouble spot.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, and can read reliably the test tube apparatus for reading of bar code of the cellanalyzer of bar code information.
