Description

Technical Field

[0001] The present invention relates to the technical field of reagent testing, in particular to a special reagent testing device for medical laboratory. Background Art

[0002] Medical laboratory departments are specialized departments within medical institutions responsible for conducting biological, microbiological, immunological, biochemical, and genetic tests and analyses on human specimens to provide medical information for disease diagnosis, treatment monitoring, and health assessment. Laboratory departments test a wide range of reagents daily, including blood and urine. Urine testing utilizes specialized urine analyzers.

[0003] Before the urine tester performs a urine sample, the patient first needs to use a test tube to collect a sample. The tester then opens the test tube and inserts a test strip into the tube to dip it in urine. The test strip is then removed and gently wiped with a paper towel to remove any excess urine adhering to the surface of the test strip to prevent dripping urine from contaminating the work surface and affecting the accuracy of the test results. Finally, the test strip is placed on the urine tester's mobile bracket, which transports the test strip into the urine tester. The urine tester then tests the urine on the test strip and displays the relevant data on the control screen.

[0004] However, when the test strip uses a paper towel to gently absorb excess urine adhering to the surface of the test strip, due to the porous structure of the paper towel, the urine absorbed by the paper towel will slowly, locally, and continuously spread on the paper towel under the action of capillary effect, and the range of the urine trace on the paper will become larger. If the same paper towel is used to wipe multiple test strips, the tester may easily cause cross-infection due to inattention and misoperation, which will affect the urine test results of the urine tester. If multiple paper towels are used to wipe multiple test strips separately or each paper only wipes a small amount of test strips, it will be more wasteful of paper. At the same time, when the tester inserts the test strip into the test tube to dip the urine, the hand may accidentally touch the test tube mouth. When the patient uses the test tube to take a sample, the test tube mouth is also likely to come into contact with urine. Even if the tester wears gloves, if the gloves touch the test tube mouth and then touch other test strips again during subsequent operations, it will cause cross-contamination between different samples, which will also affect the urine test results of the urine tester.

The upper end of the cross bar 17 is fixedly connected to a trapezoidal block 20 , which corresponds to one of the V-shaped grooves 21 .

[0029] Working principle: When testing urine, first, place the test tube 8 containing urine on the inner side of the tube rack 7, then pull out a limit plate 35, the limit plate 35 will drive the connecting column 39 to slide in the concave frame 36, and the connecting column 39 will drive the clamping block 38 to move away from the concave frame 36, and the connecting column 39 will also drive another limit plate 35 to squeeze the spring three 37, then place the upper edge of the test strip 2 between the clamping block 38 and the concave frame 36, and make the test strip 2 correspond to the center of the test tube 8 as much as possible, then release the limit plate 35, and under the action of the spring three 37, the clamping block 38 will be reset and clamp the test strip 2 between the clamping block 38 and the concave frame 36, otherwise the test strip 2 can be taken out from between the clamping block 38 and the concave frame 36, at this time, the preparation of the test tube 8 and the test strip 2 is completed.

[0030] Next, the electric push rod 2 11 is started to drive the motor 2 12, the annular frame 13 and the concave frame 36 to move downward together, and the test strip 2 will be moved downward together until the test strip 2 extends downward to a suitable depth inside the test tube 8. Then, the electric push rod 2 11 is used to drive the test strip 2 to move back to its original position. Then, the two electric push rods 1 4 are started again. Each electric push rod 1 4 will drive the mobile frame 5 connected to it to move toward the test strip 2 on the upper end of the base 40 through the spring 19. The two movable frames 5 can move together with the two motors 1 6, the absorbent paper roll 3, the winding drum 9, the cross bar 17, the concave plate 32, the clamping plate 1 31, the guide column 30, the clamping plate 2 16, the disc 29, the spring 28, the rotating shaft 33, the baffle 25, the two pulleys 26, the belt 27, the multiple arc-shaped blocks 34, the limit block 1 22, the splicing plate 24 and the limit block 2 15 until the extended portion of the absorbent paper roll 3 gently contacts one side of the test strip 2 and absorbs excess urine.

[0031] Then, the two motors 6 are started. The output shaft of the motor 6 located below the absorbent paper roll 3 rotates clockwise, while the output shaft of the motor 6 located below the take-up drum 9 rotates counterclockwise. The absorbent paper roll 3 rotates clockwise, while the take-up drum 9 rotates counterclockwise and drives the paper 23 to be stored outside the take-up drum 9 (it should be noted that the paper 23 can be unused waste paper to avoid waste). The paper 23 will also drive the protruding part of the absorbent paper roll 3 to move together, and the paper of the absorbent paper roll 3 will be released outward. When the motor 6 located below the absorbent paper roll 3 is running, it will drive the pulley 26 outside it to rotate. The pulley 26 can drive another pulley 26 to rotate through the belt 27. The other pulley 26 will drive the rotating shaft 33 to rotate on the cross bar 17. The rotating shaft 33 will drive multiple arc blocks 34 to rotate together, and rotate clockwise. The rotation of the arc block 34 close to the baffle 25 will The baffle 25 is pushed and driven to move away from the clamping plate 1 31 (in the process, the clamping plate 1 31 will also slide outside the guide post 30 and squeeze the spring 28 connected to the disc 29), then the clamping plate 2 16 connected to the baffle 25 will also move away from the clamping plate 1 31, thereby loosening the extended portion of the absorbent paper roll 3, so that the paper 23 will not be hindered by friction when driving the extended portion of the absorbent paper roll 3 to move until the arc block 34 close to the baffle 25 rotates away from the baffle 25 (it should be noted that after the arc block 34 rotates away from the baffle 25, the next arc block 34 will rotate to contact the baffle 25, and so on). At this time, under the action of the spring 28, the clamping plate 2 16 will be reset and clamp the extended portion of the absorbent paper roll 3 between the clamping plate 1 31 and the clamping plate 2 16. At this time, the extended portion of the absorbent paper roll 3 that is not contaminated by urine will be aligned with the test strip 2, and the two motors 1 6 will be turned off.

[0032] It should be noted that when the cross bar 17 moves close to the test strip 2, it will also drive the L-shaped rod 14 and the trapezoidal block 20 to move together. When the cross bar 17 moves close to the test strip 2, the trapezoidal block 20 will be inserted into a V-shaped groove 21 outside the annular frame 13. When it is necessary to absorb excess urine on the other side of the test strip 2, the motor 2 12 is started to drive the annular frame 13, the concave frame 36, the clamping block 38 and the test strip 2 to rotate counterclockwise. The annular frame 13 will drive the two V-shaped grooves 21 to rotate counterclockwise together, and the V-shaped groove 21 that cooperates with the trapezoidal block 20, combined with the Figure 4From the perspective of the embodiment, the V-shaped groove 21 pushes the inclined surface of the trapezoidal block 20 and drives the trapezoidal block 20 to move away from the annular frame 13. The trapezoidal block 20 drives the cross bar 17 to move together through the L-shaped rod 14. The cross bar 17 drives the two moving frames 5 to respectively squeeze the spring 19 connected to the two electric push rods 14. Then, the absorbent paper roll 3, the winding drum 9 and the paper 23 will also move away from the test strip 2. That is, the rotation of the test strip 2 is not hindered by the protruding part of the absorbent paper roll 3. When the annular frame 13 and the test strip are After the test strip 2 is rotated 180 degrees counterclockwise, the test strip 2 is turned over, and another V-shaped groove 21 on the annular frame 13 cooperates with the trapezoidal block 20. Under the action of spring 19, the L-shaped rod 14 and the cross bar 17 move together, and the two movable frames 5, the absorbent paper roll 3, the winding drum 9 and the paper 23 are also reset. Then, the extended portion of the absorbent paper roll 3 contacts the other side of the test strip 2, thereby absorbing excess urine on the other side of the test strip 2.

[0033] Finally, two electric push rods 14 control the absorbent paper roll 3, the reel 9, and the paper 23 to move away from the test strip 2. At this point, the test strip 2 can be removed. The test strip 2 is then placed on the movable bracket of the urine test instrument body 10, and the movable bracket sends the test strip 2 into the inspection area inside the urine test instrument body 10 to obtain the relevant test results. The urine test instrument body 10 is well known in the art and will not be described in detail.

[0034] It should be noted that each time the splint 1 31 and the splint 2 16 clamp the protruding part of the absorbent paper roll 3, they can compress the pores of the protruding part of the absorbent paper roll 3, and the clamped part each time is the position of the protruding part of the absorbent paper roll 3 close to the position where urine is adsorbed, thereby suppressing the urine from continuously diffusing to the uncontaminated protruding part under the action of capillary effect, and the splint 1 31 and the splint 2 16 can cooperate with the operation of the motor 1 6 to intermittently loosen and clamp the protruding part of the absorbent paper roll 3, and when loosened, the protruding part of the absorbent paper roll 3 can be prevented from being hindered by friction when moving toward the winding drum 9, thereby avoiding the cross-infection caused by careless misoperation when removing excess urine from the test strip 2 due to the capillary effect. At the same time, the protruding part of the absorbent paper roll 3 moves a small distance suitable for the width of the test strip 2 each time, avoiding paper waste.

[0035] It should be noted that the test strip 2 can accurately control the depth of the test strip 2 inserted into the test tube 8 through the cooperation of the electric push rod 2 11, the motor 2 12, the annular frame 13, the concave frame 36 and the clamping block 38, without the need for the inspection personnel to operate, thereby avoiding the staff's gloves from touching the tube mouth of the test tube 8 and easily causing cross-contamination when taking a new test strip 2 subsequently, and the test strip 2 can be quickly turned over to quickly absorb the excess urine on both sides of the test strip 2, which is easy to operate.

[0036] It should be noted that, under the limiting action of the first limiting block 22 and the second limiting block 15 , it can be ensured that the position of the extended portion of the absorbent paper roll 3 corresponding to the test strip 2 is always parallel to the test strip 2 .

[0037] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
