Urine analyzers are instruments for measuring chemical components in urine and have important roles in the field of medical diagnosis. A typical urine analyzer needs to place a test strip or a test card immersed in urine on a carrier, and transport the test strip or the test card to a detection site for detection. When two kinds of test devices, i.e. a test strip and a test card, can be used in the same instrument, there are generally three kinds of implementation schemes.

The first solution is to put the test strips or cards on their respective carriers, and then place the carriers on a common carrier. Like the solution disclosed in the urine analyzer of us.pat. No.7118713b2, when an operator replaces a test strip or a test card with a test card or a test strip, the operator needs to replace the carriage at the same time, and a dead angle for cleaning is formed due to the placement position of the carriage on the stage.

The second solution is to provide a test card placement location on the carrier, and perform dimension processing on the test strip carrier, so that the test strip carrier can also be placed in the test card placement location, such as the solution disclosed in the urine analyzer of us.pat. No. 6239445b1. This solution, while using a smaller test card carrier than the first solution, still requires repeated replacement of the carrier during use.

The third scheme is to make a carrier into a double-sided design, wherein the carrier usually needs a larger volume, one side is provided with a test strip placing position, and the other side is provided with a test card placing position. When replacing the test strip or the test card with the test card or the test strip, an operator needs to clean and dry the used surface of the carrier, and then connect the used surface with the instrument, and the unused surface is used for placing the test card or the test strip.

Detailed Description

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. We do not exclude that the present invention can also be implemented with other embodiments and that the structure of the present invention can be changed without violating the scope of the present invention.

As shown in fig. 1-14, the objective table for biological sample analyzer of the present invention can place both the detection board and the test paper strip on the same surface. The operator selects the detection plate or the test strip respectively according to the needs of the test items, and places the detection plate or the test strip on the objective table, completes information detection and analysis on the detection plate and the test strip, avoids frequently taking out or overturning the objective table from the biological sample analyzer, thereby effectively avoiding operation errors caused by complex operation of operators while improving the detection efficiency. Therefore, the detection plate limiting structure is arranged on the same surface, such as the front surface, of the object stage for bearing the test strip. This pick-up plate limit structure makes the pick-up plate be injectd in the suitable position of objective table to make the objective table get into biological sample analysis appearance after, the testing result on the pick-up plate just in time is located the light source detection zone.

In some embodiments, the detection plate limiting structure is a boss matched with the detection plate, or a concave hole matched with the detection plate, or a groove for accommodating the detection plate, or a combination of the boss and the groove, or a combination of the concave hole and the groove.

In the embodiment shown in fig. 1 to 10, the stage 100 is provided with a boss 111. This boss 111 is as pick-up plate limit structure, and when placing pick-up plate 200 on the objective table, the boss is used for spacing pick-up plate 200 as limit structure and pick-up plate cooperation, plays the detection position of locating the pick-up plate at the objective table. Meanwhile, when the test strip is positioned on the objective table, the boss 111 also limits the position of the test strip on the objective table, so that the detection results of the detection plate and the test strip are just positioned in a proper light source detection area of the biological sample analyzer, and the detection results of the detection plate and the test strip are accurately read by the biological sample analyzer. The raised platform also serves as a support structure for cooperating with the test strip to support the test strip 300 such that the test strip on the stage is in a substantially uniform plane.

In a further optimized design scheme, the height of the boss on the objective table is designed to ensure that the detection height of the test strip on the boss is the same as the detection height of the test strip in the detection plate on the boss. Therefore, no matter the detection plate or the test strip is positioned on the lug boss for detection, the detection plate or the test strip can be positioned in a proper light source detection area of the biological sample analyzer, and the detection results of the detection plate and the test strip are accurately read.

The sensing plate 200, in the embodiment shown in fig. 5, includes a base plate 210 and a cover plate 220. The test strip for detection is attached to the base plate 210, and the cover plate 220 covers the base plate 210 and the test strip, thereby forming the detection plate 200. The bottom plate 210 of the detection plate is provided with a concave hole 211 corresponding to the boss 111 on the back surface, and the concave hole is a limiting structure on the detection plate. In an optimized design, the concave holes 211 on the detection plate are equal in size and position and correspond to the bosses 11 on the object stage. After the detection plate 200 is positioned on the stage 100, the concave hole 211 is engaged with the boss 111 on the stage.

The number of the bosses 111 is not limited, as long as the bosses can be matched with the concave holes of the detection plate, so that the detection plate can be placed at the correct detection position of the objective table. The number of the bosses 111 may be one or more. Specifically, the number of the bosses 111 is 1 to 5; in one specific embodiment, there are 3 bosses 111. The number of detection plate recesses 211 may be the same as or different from the number of bosses 111 on the stage. The number of the concave holes 211 is the same as that of the bosses 111, for example, when the number of the bosses 111 is three, the number of the concave holes 211 is also three. The number of the concave holes 211 is different from the number of the convex blocks 111, for example, when the number of the convex blocks 111 is three, the number of the concave holes 211 is four, wherein three concave holes correspond to the convex blocks, and the rest one concave hole can be used for other purposes or is idle when being matched with the objective table.

The bosses on the object stage can be uniformly distributed and arranged. In another preferred embodiment, the uneven arrangement of the bosses 111 is used to identify and define the orientation of the inspection board 200 on the stage 100, so as to ensure that the orientation of the inspection board 200 on the stage 100 is not wrong. The inaccurate or undetectable detection result caused by the reversal of the direction of the detection board 200 or the deviation of the detection board from the light source detection area of the biological sample analyzer is avoided. In the case where the bosses 111 are not uniformly arranged on the stage 100, specific ways include, but are not limited to: the bosses 111 are not arranged on the same straight line; alternatively, the pitches between the bosses 111 are different. For example, when there are two bosses 111, the central connecting line of the two bosses is not parallel to the horizontal central axis or the vertical central axis of the detection plate; for another example, when the number of the convex strips 111 is three or more, the distance between two adjacent convex strips 111 is different; or three or more bosses 111 are not provided in a straight line.

The arrangement of the concave holes 211 on the back surface of the detection plate base plate 210 is the same as the arrangement of the bosses 111 on the object stage 100. For example, when the bosses 111 are arranged in a straight line and have different pitches, the concave holes 211 are arranged in a straight line and have different pitches, and the pitches of the concave holes 211 are the same as the pitches of the bosses 111 in a one-to-one correspondence. When the projection 111 is located on the center line of the stage 100, the recess hole 211 is arranged on the center line of the base plate 210.

The recesses 211 may or may not penetrate the entire base plate 210 on the back of the base plate 210. When the boss on the objective table is assembled with the concave hole on the detection plate in a matching manner, the boss cannot influence the detection of the test paper strip in the detection plate.

In the embodiment shown in fig. 1-10, the area of the stage 100 in which the detector plate is stored is provided with a recess 110, the recess 110 of the stage being adapted to receive and retain the detector plate, and in some embodiments, a boss 111 is provided within the recess 110. The lug boss and the groove are combined to limit the detection plate. In addition, since the groove forms a large urine containing space, urine overflowing from the test strip 300 or the detection plate 200 can be contained. On the one hand, collect the urine in the recess and can not flow out the objective table and cause the pollution to the environment, on the other hand, because the recess bottom has certain distance with test paper strip or pick-up plate put on the boss, collect and can't contact test paper strip or pick-up plate in the urine that overflows of recess bottom to avoid different urine samples to pollute test paper strip or pick-up plate that are detecting. In a further optimized design, two side walls of the groove 110 are provided with raised strips 112 protruding from the side walls; the ribs 112 are positioned adjacent the ends of the grooves 110; the distance between the ribs 112 of the two side walls is equal to the width of the detection plate 200. The convex strips 112 on the two side walls are contacted and clamped with the side walls of the detection plate 200, so that the detection plate 200 is better fixed in the groove 110. One or more ribs 112 are provided on both sidewalls near both ends of the groove 110. The protrusions 112 respectively arranged on the two sidewalls of the groove 110 are symmetrical.

To facilitate access of the detector plate 200 to the stage 100, particularly from the recess, a depression 230, such as a symmetrically designed depression 230, is provided in the detector plate intermediate the two side walls of the base plate 210 and cover plate 220. When the detection plate is taken out from the groove, the space formed by the concave part can facilitate the fingers of an operator or the gripping clips of the mechanical arm to extend into the concave part to grip the detection plate.

In the embodiment shown in fig. 12-13, the position limiting structure of the detection plate on the stage is a concave hole 111', and the arrangement mode refer to the arrangement and the arrangement of the boss 111. Correspondingly, be equipped with on the back of pick-up plate 200 ' bottom plate with objective table shrinkage pool 111 ' complex pick-up plate arch 211 ', this pick-up plate arch 211 ' quantity and mode of arrangement all with objective table shrinkage pool 111 ' one-to-one, when pick-up plate 200 ' was located objective table 100 ', pick-up plate arch 211 ' one-to-one on the pick-up plate 200 ' inserted in the objective table shrinkage pool 111 ' on the objective table 100 ', made pick-up plate 200 ' by injecing on objective table 100 '.

The cross section of the boss or the concave hole of the limiting structure can be different in shape. For example, when there are 3 bosses, two of the bosses may be square and the third boss may be circular. Correspondingly, the concave holes on the detection plate matched with the detection plate are also respectively square and round.

The test strip 300 of the embodiment shown in fig. 8 includes a substrate 301 to which a test strip 302 is attached. The test paper may be urine joint test paper, lateral flow test paper, or the like.

The object stage is provided with a test strip positioning structure. For example, the positioning structure for positioning the test strip on the object stage is a slot or a convex pin. When the positioning structure is a convex nail, the convex nail is matched with the positioning structure, and the test strip is provided with a test strip hole. The test strip is clamped and positioned by the slot, or the test strip hole is matched with the convex pin on the objective table to position the test strip.

In the embodiment shown in fig. 1-10, the test strip positioning structure on the stage of the object carrier 100 is two slots, i.e., a first slot 120 and a second slot 130, corresponding to two ends of the test strip. The first slot 120 and the second slot 130 are respectively disposed at two ends of the groove 110, and position and support the test strip 300. In some embodiments, the first slot 120 is located at an end of the object stage 100 to facilitate insertion of the test strip 300 into the object stage 100 from the end of the object stage 100. When a liquid sample is added to the entire elongated test strip 300, the weight of the liquid will cause the middle of the test strip to sag, and when the sag prone middle is supported by the raised platform, it is ensured that the entire test strip is in nearly the same plane at the test site. Therefore, to ensure better support for the test strip 300, the center of the boss 111 is aligned with the center of the first slot 120 and the center of the second slot 130. That is, when the test strip 300 is located on the object stage 100, the two ends of the test strip 300 are respectively located in the first slot 120 and the second slot 130, and the boss 111 is located right below the test strip 300. The detection board 200 is placed in the area of the groove 110, the two ends of the test strip are placed in the clamping

grooves

120 and 130, and the thickness of the detection board 200 is larger than that of the test strip 300, so that in an optimal design, the depth of the groove 110 is larger than that of the first clamping groove 120 and the second clamping groove 130, and therefore after the test strip and the detection board are placed on the objective table, the detection result areas on the test strip and the detection board can be located at the same height and in a proper light source area. In a more specific embodiment, in order to ensure that the test strips are located at the same horizontal height, the height of the boss 111 in the groove 110 is the same as the height of the first slot 120 and the second slot 130 higher than the groove 110; or, the depth of the groove 110 is the same as that of the clamping

grooves

120 and 130, so that the test strip 300 is conveniently manufactured and integrally formed, meanwhile, the first clamping groove 120 and the second clamping groove 130 are both provided with the protruding blocks 122 and 132, and the heights of the protruding blocks 122 and 132 are the same as that of the bosses 111 in the groove, so that the test strip 300 in the clamping grooves and the groove is ensured to be in a horizontal state. The widths of the first clamping groove 120 and the second clamping groove 130 are the same as the width of the test strip 300, so that the clamping grooves can better clamp and position the test strip. Alternatively, two ends of the first card slot 120 are provided with openings 121; the width of the opening 121 is the same as the width of the test strip 300. That is, the side wall of the test strip 300 is engaged with the opening 121 of the first card slot, so that the first card slot 120 is fixed to one end of the test strip 300. Meanwhile, one end of the second card slot 130 is opened 131; symmetrical protrusions 133 are arranged at the opening 131. And, two side walls of the end of the second slot 130 are provided with symmetrical protrusions 133.
