Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a sample analyzer and reagent tray. Background Technology

[0002] Sample analyzers are widely used testing instruments in the field of in vitro diagnostic technology. They can obtain clinical diagnostic information by testing human blood and body fluid samples, providing a basis for disease diagnosis and assessment of bodily functions.

[0003] The reagent tray is an integral part of the sample analyzer, used to store the reagents required for testing. Since most reagents need to be refrigerated in the reagent tray, the temperature difference between the reagent tray and the external environment can easily cause condensation to form on the surface of the reagent tray when the reagent bottles are replaced. This keeps the reagent tray in a humid environment for a long time, which can easily lead to mold growth and affect the instrument's detection effect. In addition, most existing reagent trays are one-piece molded structures, making it impossible for operators to clean and replace the reagent tray in a timely manner. Summary of the Invention

[0004] This utility model discloses a sample analyzer and reagent tray to solve the problem in the prior art where condensation easily forms on the surface of the reagent tray, making it impossible to clean and replace it in a timely manner.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A reagent tray includes an annular base plate, with multiple reagent bottle holders snapped onto the circumference of the annular base plate; the upper surface of the reagent bottle holders is inclined outward and is inclined relative to the annular base plate.

[0006] Furthermore, the reagent bottle holder includes a tray and a reagent platform disposed on the tray; the reagent platform is recessed downward to form an inner ring receiving groove and an outer ring receiving groove; multiple inner ring receiving grooves and multiple outer ring receiving grooves are provided; the multiple inner ring receiving grooves and outer ring receiving grooves are arranged alternately.

[0007] Furthermore, an arc-shaped protrusion is provided on one side of the tray corresponding to the outer ring receiving groove; an arc-shaped groove is provided on the tray on the side opposite to the arc-shaped protrusion; both the arc-shaped protrusion and the groove are smoothly connected to the tray.

[0008] Furthermore, both the inner and outer ring receiving grooves are provided with inclined placement platforms for placing reagent bottles.

[0009] Furthermore, the angle α between the upper surface of the inclined placement platform and the horizontal plane is 5-15°.

[0010] Furthermore, an adapter seat is provided on the placement platform; the adapter seat is provided with an opening.

[0011] Furthermore, a recessed area is provided on the inner side of the adapter corresponding to the opening on the adapter.

[0012] Furthermore, multiple reagent bottle holders are snapped together to form a circular inner ring receiving groove and an outer ring receiving groove; each of the outer ring receiving grooves is provided with a first scanning port on the side away from the center; each of the outer ring receiving grooves is provided with a second scanning port, and the second scanning port is connected to the inner ring receiving groove.

[0013] Furthermore, the inner side of the annular base plate extends upward to form a support plate; reinforcing ribs are provided on the support plates on both sides of the reagent bottle holder; a positioning post is provided on the annular base plate between the reinforcing ribs on both sides; and a positioning hole is provided on the reagent bottle holder corresponding to the positioning post.

[0014] A sample analyzer includes the reagent tray described above.

[0015] This utility model adopts the above technical solution and has the following advantages: This invention utilizes a tilted reagent bottle holder. During sample analyzer operation, condensate formed inside the reagent tray can slide down the slope to the bottom of the tray and be drained to the outside by a conduit located at the bottom of the tray, preventing condensate from accumulating on the surface of the reagent bottle holder for extended periods.

Detailed Implementation

[0018] The technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 , 2 As shown, a reagent tray includes an annular base plate 1, and a plurality of reagent bottle holders 2 are snapped together around the annular base plate 1; the upper surface of the reagent bottle holders 2 is inclined outward and is inclined relative to the annular base plate 1.

[0020] This invention utilizes a tilted reagent bottle holder 2. During sample analyzer operation, condensate formed inside the reagent tray can slide down the slope to the bottom of the tray and be drained to the outside by a conduit located at the bottom of the tray, preventing condensate from accumulating on the surface of the reagent bottle holder 2 for extended periods. Furthermore, if mold forms on the surface of the reagent tray due to alternating hot and cold environments after prolonged use, the snap-fit ​​reagent bottle holder 2 allows operators to easily remove the bottle for replacement or cleaning, preventing mold from affecting the instrument's detection accuracy.

[0021] like Figure 3 , Figure 4 As shown, the reagent bottle holder 2 includes a tray 3 and a reagent platform 4 disposed on the tray 3; the reagent platform 4 is recessed downward to form an inner ring receiving groove 5 and an outer ring receiving groove 6; multiple inner ring receiving grooves 5 and multiple outer ring receiving grooves 6 are provided; multiple inner ring receiving grooves 5 and multiple outer ring receiving grooves 6 are arranged alternately.

[0022] This utility model provides multiple inner and outer ring receiving grooves on each reagent bottle holder 2, so that when multiple reagent bottle holders 2 are spliced ​​together, an inner and outer ring receiving groove structure can be formed on the circumference of the annular base plate 1; and the reagent bottle holder 2 structure including multiple inner and outer ring receiving grooves can facilitate the sequential arrangement of multiple reagent bottle holders 2 on the circumference of the annular base plate 1.

[0023] Multiple reagent bottle holders 2 are snapped together to form an inner ring receiving groove 5 and an outer ring receiving groove 6; the inner ring receiving groove 5 and the outer ring receiving groove 6 are staggered; each outer ring receiving groove 6 is provided with a first barcode scanning port 7 on the side away from the center, for scanning the outer ring receiving groove 6 and the reagent bottles; each outer ring receiving groove 6 is provided with a second barcode scanning port 8, which is connected to the inner ring receiving groove 5, for scanning the inner ring receiving groove 5 and the reagent bottles.

[0024] This invention arranges the inner and outer ring receiving grooves alternately, so that an inner ring receiving groove 5 is formed between every two outer ring receiving grooves 6. The space between two outer ring receiving grooves 6 can be used to set a second scanning port 8 so that the scanning mechanism can scan and identify the inner ring receiving groove 5 and the reagent bottle.

[0025] An arc-shaped protrusion 9 is provided on one side of the support plate 3 corresponding to the outer ring receiving groove 6; an arc-shaped groove 10 is provided on the support plate 3 on the opposite side of the arc-shaped protrusion 9; both the arc-shaped protrusion 9 and the arc-shaped groove 10 are smoothly connected to the support plate 3.

[0026] When multiple reagent bottle holders 2 are arranged circumferentially on the annular base plate 1, the arc-shaped protrusions 9 and arc-shaped grooves 10 between adjacent reagent tray holders 2 are adapted to better engage between adjacent reagent bottle holders 2 and avoid relative sliding between reagent tray holders 2.

[0027] Furthermore, each accommodating slot is provided with an inclined placement platform 11; the placement platform 11 is inclined outward for placing reagent bottles.

[0028] When the reagent bottle is placed on the tilted platform 11, the bottom of the reagent bottle is tilted, and the reagent inside gathers to the tilted side. When the reagent in the reagent bottle becomes less, it is easier for the reagent needle to draw up the reagent at the bottom.

[0029] like Figure 5 As shown, the angle α between the upper surface of the inclined placement platform 11 and the horizontal plane is 5-15°.

[0030] The angle setting of this utility model can avoid interference between the reagent needle and the mouth of the reagent bottle when the angle is too large.

[0031] like Figure 3-5 As shown, a detachable adapter seat 12 is provided on the placement platform 11 for placing reagent bottles of different sizes. Each adapter seat 12 has an opening 13 on the side facing the barcode scanner for the barcode scanner to scan the adapter seat 12 and the reagent bottle.

[0032] The detachable adapter 12 can be replaced at any time according to the size of the reagent bottle, making it convenient to place the reagent bottle.

[0033] A recessed area 14 is provided on the inner side of the adapter 12 corresponding to the opening 13 on the adapter 12, for attaching an identifiable label. The recessed area 14 prevents the label from being directly attached to the surface of the adapter 12, thus avoiding damage to the label due to long-term wear and tear from the reagent bottle. Here, the identifiable label can be used to identify whether a reagent bottle is present in the adapter 12. When the scanning mechanism can scan the label, it indicates that no reagent bottle is present in that location.

[0034] A spring piece 15 is provided along the periphery of the adapter seat 12. When the reagent bottle is placed in the adapter seat 12, it can abut against the spring piece 15, providing an inward holding force for the reagent bottle and achieving reliable positioning of the reagent bottle; during the transportation of the reagent bottle tray, the reagent bottle is prevented from slipping or tipping over.

[0035] like Figure 6 As shown, the inner side of the annular base plate 1 extends upward to form a support plate 16; the support plates 16 on both sides of the reagent bottle holder 2 are provided with reinforcing ribs 17; the annular base plate 1 between the two reinforcing ribs 17 is provided with a positioning post 18; the reagent bottle holder 2 corresponding to the positioning post 18 is provided with a positioning hole 19.

[0036] When the operator installs the reagent bottle holder 2 onto the annular base plate 1, the reagent bottle holder 2 can be placed downwards along the reinforcing ribs 17 on both sides to prevent the reagent bottle holder 2 from tilting and affecting the placement of other reagent bottles. At the same time, combined with the setting of the positioning column 18, the entire reagent bottle holder 2 can be stabilized to prevent shaking and interference with the placement of other reagent bottle holders.

[0037] This utility model also discloses a sample analyzer, including the reagent tray described above.

[0038] The above are merely embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model shall be included within the scope of the claims of this utility model pending approval.
