The Handheld analysis that the present embodiment relates to, the collection of image uses imaging apparatus, what imaging apparatus adopted is high definition CMOS camera, pictures taken is clear, make the analysis of processing module more quick, movement images required time is short, obtains a result quicker, and the processing power of image is strong, makes the accuracy of testing result greatly improve.
The device interior cavity of the hand-held analysis that the present embodiment relates to is separated, and by parts such as cavity, each supports, reduces dust to the impact of device interior cleanliness factor.
The hand-held analysis that the present embodiment relates to, by the elastomeric element of the opening part of box body and the cooperation of baffle plate, form elastic opening, the stopping screens that the first handle that elastic opening and test card put and the surface of second handle form relative test paper cutting ferrule outstanding designs, guarantee that test card cover is inserted and secured on assigned address, equipment possesses certain anti-seismic performance, can mobile device in testing process.
The detection method of the Handheld analysis that the present embodiment relates to, does not need in testing process first to insert blank test strips at every turn.Two kinds of situations are only only had to need to read blank card: 1, in production of machinery process, need to read blank test strips, the illumination distribution curve storage detecting the machine makes reference; 2, the product of new batch, needs to read blank test strips, to distinguish the gray difference of different batches test strips substrate.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
