Description
Technical field
The present invention relates to medical treatment to detect assistive device field, in particular to test tube end face two-dimensional barcode information identifier.
Background technique
Blood test tube be mainly used for taking a blood sample blood of human body when storage utensil as a blood, need after blood sampling in blood
Test tube marked thereon is by the relevant information of blood sampling people, in order to which the testing staff of hospital effectively can quickly and effectively detect quilt
The associated blood sample information of blood sampling people, while entering relevant information into computer system；And it needs first to understand before blood sampling
By the information of blood sampling people, the information for the people that takes a blood sample then is generated into bar code or two dimensional code, but due to the cover of blood test tube ratio
It is smaller, two dimensional code can only be used, and two dimensional code is also comparatively small, when testing staff carries out barcode scanning, barcode scanning gun is also difficult to induce
Carry out the information in two dimensional code, cause waste of time, delays the efficiency of detection.How quickly, clearly with barcode scanning gun to blood
Two dimensional code on liquid test tube carries out barcode scanning, is one and needs urgent problem to be solved.
Publication number CN201721562045.3 amplifies optical projection system, the scheme of the utility model convenient for the two dimensional code of barcode scanning
In, amplify optical projection system, including meeting-place dais using convenient for the two dimensional code of barcode scanning, further includes that two dimensional code is installed on the dais of meeting-place
Acquisition device, the two dimensional code acquisition device include the rectangle transverse slat for being parallel to dais table top and one perpendicular to rectangular
The rectangle straight panel of shape transverse slat long side, one end that another straight flange and straight panel of the transverse slat are not connect with transverse slat are additionally provided with
Glass plate is additionally provided with the two dimensional code acquisition system connecting with projection device in the two dimensional code acquisition device.Using above-mentioned system
System, the people that meeting-place needs to share oneself two dimensional code only need to be placed in mobile phone under two dimensional code acquisition device, open the social activity of oneself
The projection to two dimensional code can be realized in two dimensional code, system, solves since meeting-place area is larger, the people of heel row can not closely sweep
Retouch the two dimensional code on mobile phone, it is necessary to it tries every possible means the two dimensional code on mobile phone to project, and some two dimensional codes are real-time changes
, it can not be prefabricated in PPT, the prior art is difficult to the problem of being projected.Be additionally provided on the table top at the dais with it is described
The matched protrusion of transverse slat projecting edge.By above structure, protrusion encloses rectangular border, and user only needs to set mobile phone
In scanning in rectangular border, can be completed, the two dimensional code on mobile phone screen is placed in two dimensional code acquisition dress convenient for operator
In the acquisition range set.
Existing technology is on the screen at the dais that the two dimensional code on direct scanning cell phone screen projects to meeting-place, therein
Two dimensional code be not it is too small, will not influence the identification of normal two dimensional code, high-visible as long as the information of the inside directly scans, not shadow
Ring normal barcode scanning.And its projection is also normal projection pattern, principle and reality with this programme two-dimensional barcode information identifier
There is also biggish different in existing means.
Summary of the invention
In view of above content, it is necessary to test tube end two-dimensional barcode information identifier is provided, the identifier by magnifying glass and
Barcode scanning gun shares, while using automatic regulation function, amplifies the information of two dimensional code, synchronous to use scanning recognition or skill of taking pictures
Art transmits two-dimensional barcode information, is finally reached the effect of acquisition test tube corresponding data.
