If the reagent strip 5 is judged to enter the two channels 8, the card feeding assembly motor 341 drives the card feeding assembly 34 to transport the reagent strip 5 to the entrance position of the two channels 8 through the card feeding assembly belt 342, and the two-channel pushing assembly motor 331 drives the two-channel pushing assembly 33 to push the reagent strip 5 into the two channels 8 through the two-channel pushing assembly belt 332. After the reagent strip 5 is incubated in the first channel 7 and the second channel 8 for a certain period of time, if the reagent strip 5 in the first channel 7 needs to be tested, the detection component motor 361 conveys the detection component 36 to the outlet position of the first channel 7 through the detection component belt 362, the channel pushing component motor 321 drives the channel pushing component 32 through the channel pushing component belt 322 to push the reagent strip 5 onto the detection component 36, the detection component motor 361 drives the detection component 36 through the detection component belt 362 to convey the reagent strip 5 to the lower part of the light path detection module 31, the LED signal flicker and the photoelectric conversion in the light path detection module 31 are matched to complete one-time detection, the fluorescence signal intensity of different positions of a certain detection position on the reagent strip 5 is tested, and the test is completed. After the test is completed, detecting element 36 transports reagent strip 5 to losing bayonet 6, loses a calorie of subassembly motor 351 and drives through the lead screw and lose a calorie of subassembly 35 and return, and reagent strip 5 falls into in the waste bin 9 from losing bayonet 6. If the reagent strip 5 in the two channels 8 needs to be tested, the detection component motor 361 conveys the detection component 36 to the outlet position of the two channels 8 through the detection component belt 362, the two-channel pushing component motor 331 drives the two-channel pushing component 33 through the two-channel pushing component belt 332, the reagent strip 5 is pushed to the detection component 36, the detection component motor 361 drives the detection component 36 through the detection component belt 362 to convey the reagent strip 5 to the lower part of the light path detection module 31, the detection is completed for one time by matching with LED signal flicker and photoelectric conversion in the light path detection module 31, the fluorescence signal intensity of different positions of a certain detection position on the reagent strip 5 is tested, and the test is completed. After the test is completed, detecting element 36 transports reagent strip 5 to losing bayonet 6, loses a calorie of subassembly motor 351 and drives through the lead screw and lose a calorie of subassembly 35 and return, and reagent strip 5 falls into in the waste bin 9 from losing bayonet 6.
Mirror reflection type photoelectric switches are arranged at the upper edge of the waste bin 9 to detect whether reagent strips in the waste bin 9 are filled, and diffuse reflection photoelectric switches are arranged on the side faces of the waste bin 9 to detect whether the reagent strips are put into the waste bin 9.
The upper heating plate 38 is provided with a diffuse reflection photoelectric switch corresponding to the vicinity of the card insertion opening 4, and detects whether the reagent strip 5 is inserted in place.
The working process of the push handle assembly is as follows:
the handle assembly is composed of a channel handle assembly 32 and a two-channel handle assembly 33, and the channel handle assembly 32 and the two-channel handle assembly 33 are composed of identical parts, so parts of the two-channel handle assembly 33 are not labeled in the fifth drawing. Four pusher assembly guide shafts 323 of the pusher assembly are fixed to the upper heating plate 38. When the reagent strip 5 is located at the entrance position of a channel 7, the pushing finger 327 of a channel pushing assembly 32 in the reset position pushes the reagent strip 5 into a channel 7, and then retracts to the reset position, and the reagent strip 5 is incubated in a channel 7 for a certain period of time. When the reagent strip 5 is located at the entrance position of the two-channel 8, the pushing finger 327 of the two-channel pushing assembly 33 in the reset position pushes the reagent strip 5 into the two-channel 8, and then retracts to the reset position, and the reagent strip 5 is incubated in the two-channel 7 for a certain period of time. If the system needs to test a reagent strip 5 in a channel 7, the pusher finger 327 of a channel pusher assembly 32 pushes the reagent strip 5 onto the detecting assembly 36 waiting at the exit position of a channel 7, and then returns to the reset position. If the system needs to test a reagent strip 5 in the two-channel 8, the pusher finger 327 of the two-channel pusher assembly 33 pushes the reagent strip 5 onto the detecting assembly 36 waiting at the exit position of the two-channel 8, and then returns to the reset position.
Four pushing handle slotted holes 10 are formed in the upper heating plate 38, the pushing handle bottom plate 326 can extend into the first channel 7 and the second channel 8 through the four pushing handle slotted holes 10, and the width of the pushing handle slotted hole 10 is correspondingly small due to the fact that the pushing handle bottom plate 326 is a sheet metal bending part with small thickness, and therefore excessive dissipation of heat in the first channel 7 and the second channel 8 can be prevented.
A handle spring 328 is mounted to the rear end of the handle finger 327. The advantage of this structure is, can play about buffering when promoting reagent strip 5 for the action that promotes to go forward is more steady.
It should be noted that the touch display panel 1, the thermal printing module 2, the movement 3, the upper heating plate 38, the lower heating plate 39 and other components are not the main innovation point of the present invention, and therefore, the structure and the operation principle thereof are not further described.
