Description

A kind of hand-held fast detector

technical field:

The utility model relates to a kind of detector, and particularly a kind of hand-held fast detector, can carry out photochemistry, and then obtains the blood constituent content of being correlated with intuitively.

background technology:

Along with scientific and technological progressive medical and health care system modernization day by day, particularly various detecting instruments are more and more complete, more and more advanced, biological chemistry detector is exactly one of them, in clinical medicine, act on great, can make accurate measurement to the content of certain composition in blood, and supply on this basis clinical diagnosis reference, significant, but this detector generally is desk-top, involve great expense, fixed placement is at control laboratory, lack mobile dirigibility, for the community that does not configure this detector, clinic, families etc. among a small circle demand still cannot meet, still await technological innovation miniaturization, portability, make its popularity rate higher, be applied to wider scope.

utility model content:

In order to address the above problem, the utility model provides a kind of hand-held fast detector, and small and exquisite portable community, clinic, the family of being applicable to, carries out fast detecting.

The technical solution adopted in the utility model is: a kind of hand-held fast detector, mainly comprise master controller, bar-code identification module, optical sampling module, control module, display module, data transmission module, RS232 communication interface and power supply, it is characterized in that: master controller is connected with bar-code identification module, optical sampling module, control module, display module, data transmission module, RS232 communication interface and power supply respectively.

Described master controller main circuit is built and is formed by microcontroller LM3S1958, nonvolatile memory FM25265 or AT25128, clock chip SD2405AP, RS232 level transferring chip SP3232E.

Described electric power main circuit is made up of battery, DC/DC switching mode step-down controller TPS5410 and linear DC voltage stabilizer REG1117-3.3, provides respectively 5V and 3.3V two groups of working powers; Backlight electric power adopts micro-power supply booster type voltage stabilizer SP6690, and its on off state is controlled by microcontroller LM3S1958 management.
