In addition, according to different changes of factors such as the structure and the space of the drug detector 100, the structural configuration of the driving module 33 may be modified appropriately, so that when the reagent card holding module 31 and the sample holding module 32 can be controlled to move in opposite directions by driving of the driving module 33, the reagent card held by the reagent card holding module 31 can pick up the sample held by the sample holding module 32, thereby realizing detection of the sample.
For example, the structural configuration of the driving module 33 may also be a structural form including a first swing arm, a second swing arm and a driving mechanism, wherein the first swing arm, the second swing arm is hinged to the housing 101, the reagent card holding module 31 is installed on the first swing arm, the sample holding module 32 is installed on the second swing arm, the driving mechanism drives the first swing arm, the second swing arm moves in opposite directions or back to back, and further the first swing arm and the second swing arm can intersect at a set position, e.g., along the direction of the first swing arm and the direction of the second swing arm moving in opposite directions, the reagent card holding module 31 and the sample holding module 32 are handed over each other, the joint is the set position, so that the reagent card held by the reagent card holding module 31 can be stained with a sample held by the sample holding module. Of course, the driving module 33 may be disposed in other structures, which are not listed here.
Drug detector second embodiment:
as shown in FIG. 10, the inventive concept of the first embodiment of the drug monitor is applied, and the second embodiment of the drug monitor is different from the first embodiment in that the camera module 230 of the second embodiment comprises a camera assembly 2301 and a telescopic assembly 2302, wherein the telescopic assembly 2302 is installed in the housing, the end of the telescopic assembly 2302 can extend out of the housing along the axial direction of the telescopic assembly 2302, and the camera assembly 2301 is arranged at the end of the telescopic assembly 2302.
When the camera module 230 is needed, the end of the telescopic assembly 2302 extends out of the housing, and then drives the camera assembly 2301 on the end to extend out of the housing. When needs carry the drug detector, the tip of flexible subassembly 2302 contracts from the casing outside in to the casing, and then drives the subassembly 2301 of making a video recording on the tip and retrieve to in the casing, when reducing the space that the drug detector occupied, protects subassembly 2301 of making a video recording.
In conclusion, the drug detector provided by the invention can avoid the problems of misjudgment during detection, untimely update of detection data, omission and deficiency of data registration, low detection efficiency, easiness in information misreading and packet dropping, low detection automation degree and the like in the traditional drug detection, and has the advantages of simplicity in use, high information entry speed, high detection precision and realization of automation of the detection process.
Finally, it should be emphasized that the above-described preferred embodiments of the present invention are merely examples of implementations, rather than limitations, and that many variations and modifications of the invention are possible to those skilled in the art, without departing from the spirit and scope of the invention.
