Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a reagent cold storage device. Background Technology

[0002] In vitro diagnostic testing equipment is used to detect specific chemical substances in reagents. With the rapid development of modern medical technology, in vitro diagnostic testing equipment plays an indispensable role in the early screening, accurate diagnosis and monitoring of treatment effects of diseases.

[0003] The storage environment of reagents can affect the accuracy of reagent test results. Therefore, existing reagents are preserved at low temperatures using reagent refrigeration storage devices. These devices typically have multiple storage chambers for reagent bottles. When testing reagents, an operating arm moves a suction needle above the storage chamber to aspirate the reagent from the bottle and add it to the testing equipment.

[0004] Because each storage chamber is located differently, the aspiration needle requires moving the operating arm horizontally and vertically to align with the storage chamber each time it draws reagent. This increases the difficulty of moving the operating arm, prolongs reagent aspiration time, and reduces detection efficiency. Furthermore, the reagent at the bottom of the reagent bottle is difficult to aspirate during aspiration, resulting in a significant amount of residual reagent and waste. Utility Model Content

[0005] The purpose of this invention is to provide a reagent refrigeration storage device that can reduce the difficulty of moving the operating arm, improve detection efficiency, and reduce reagent residue at the bottom of the reagent bottle.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A reagent cold storage device, comprising:

[0008] A reagent tray, wherein at least one reagent placement area is provided on one side of the reagent tray, the reagent placement areas are arranged in concentric circles with the center of the reagent tray as the center, and each reagent placement area is provided with a plurality of mounting parts for mounting reagent bottles, and each mounting part can be tilted at the same angle relative to the central axis of the reagent tray to mount the reagent bottle.

[0009] A driving mechanism is connected to the reagent tray and is capable of driving the reagent tray to rotate.

[0014] Optionally, the drive mechanism further includes a first cold conduction isolator, one side of which is fixedly connected to one end of the drive shaft facing the reagent tray, and the other side is fixedly connected to the reagent tray.

[0015] Optionally, the reagent refrigeration storage device further includes a cold conduction chassis, the reagent tray is disposed above the cold conduction chassis and is clearance-fitted with the cold conduction chassis, the refrigeration component is connected to the side of the cold conduction chassis facing away from the reagent tray, the cold conduction chassis is provided with mounting holes, the drive shaft passes through the mounting holes and is fixedly connected to the reagent tray.

[0016] Optionally, the reagent refrigeration storage device further includes a second cold conduction isolation element, the first end of which is connected to the side of the cold conduction chassis facing away from the reagent tray, and the second end of which is connected to the motor.

[0017] Optionally, the reagent refrigeration storage device further includes a heat insulation ring, which is installed in the mounting hole, and the drive shaft passes through the inner ring of the heat insulation ring and is rotatably connected to the heat insulation ring.

[0020] The beneficial effects of this utility model are:

[0021] This invention provides a reagent refrigeration storage device, comprising a reagent tray, a drive mechanism, and a refrigeration component. The reagent tray has at least one reagent placement area arranged concentrically around the center of the tray. Each reagent placement area has several mounting components for holding reagent bottles. The drive mechanism is connected to the reagent tray and can drive the tray to rotate. When aspirating reagent from a bottle, the drive mechanism simply rotates the reagent tray, aligning the mounting component containing the bottle to the corresponding position for the aspirator. The operating arm then moves vertically to complete the aspiration, reducing the difficulty and time required for arm movement and improving detection efficiency. Furthermore, rotating the reagent tray allows for convenient handling of reagent bottles in the same location. The presence of at least one reagent placement area with several mounting components allows the tray to hold a larger number of reagent bottles, increasing the utilization rate of the tray's space. Furthermore, each mounting component allows for the same angle of tilt relative to the central axis of the reagent tray when installing reagent bottles. This ensures that when each bottle is rotated to the corresponding position of the aspiration needle, the tilt direction is identical, guaranteeing that the needle can reach the bottom of each bottle. This minimizes reagent residue at the bottom of the bottle when aspirating, preventing waste. A cooling unit is located on the side of the reagent tray facing away from the reagent placement area. This unit cools the tray, maintaining a low-temperature environment beneficial for reagent preservation. Attached Figure Description

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0041] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0043] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0044] like Figures 1-6 As shown, this embodiment provides a reagent refrigerated storage device, which includes a reagent tray 1, a driving mechanism 3, and a refrigeration component 4. At least one reagent placement area is provided on one side of the reagent tray 1. Each reagent placement area is arranged concentrically with the center of the reagent tray 1 as the center. Each reagent placement area is provided with several mounting parts 11 for mounting reagent bottles 2. The driving mechanism 3 is driven and connected to the reagent tray 1, and the driving mechanism 3 can drive the reagent tray 1 to rotate. When aspirating reagent from the reagent bottle 2, simply drive the reagent tray 1 to rotate via the driving mechanism 3, rotating the mounting part 11 containing the reagent bottle 2 to the position corresponding to the aspiration needle 100. The operating arm can then move vertically to insert into the corresponding reagent bottle 2 to complete the reagent aspiration, reducing the difficulty of moving the operating arm, reducing the time spent moving the operating arm, and improving detection efficiency. Simultaneously, when picking up or placing reagent bottles 2, rotating the reagent tray 1 allows for picking up or placing reagent bottles 2 in the same position, facilitating operation.

[0045] The reagent tray 1 has at least one reagent placement area, on which several mounting components 11 are provided. This allows the reagent tray 1 to hold a larger number of reagent bottles 2, increasing the utilization rate of the space on the reagent tray 1. Furthermore, each mounting component 11 can be installed with a reagent bottle 2 at the same angle relative to the central axis of the reagent tray 1. This ensures that when each reagent bottle 2 is rotated to the position corresponding to the aspiration needle 100, the tilt direction is the same, ensuring that the aspiration needle 100 can reach the bottom of each reagent bottle 2. When the aspiration needle 100 draws reagent from the reagent bottle 2, it can reduce the amount of reagent residue at the bottom of the reagent bottle 2, avoiding reagent waste. A cooling component 4 is located on the side of the reagent tray 1 facing away from the reagent placement area. The cooling component 4 can cool the reagent tray 1, keeping it in a low-temperature environment, which is beneficial for reagent preservation.

[0046] Specifically, such as Figure 2 and Figure 3 As shown, reagent tray 1 is a circular plate. The material of reagent tray 1 can be a metal or other material with high thermal conductivity, allowing the low temperature of the cooling component 4 to be effectively transferred to reagent tray 1. There are two reagent placement areas: one near the center of reagent tray 1 and the other away from the center. The reagent placement area near the center can have 4-10 mounting components 11, such as 4, 6, or 10. The reagent placement area away from the center can have 10-20 mounting components 11, such as 10, 14, or 20. In other embodiments, the number of reagent placement areas and mounting components 11 is determined according to the size of reagent tray 1.

[0047] Specifically, such as Figure 2 As shown, the refrigeration assembly 4 includes a cooling element 41, a water-cooled heat exchanger 42, and a mounting bracket 43. The cooling element 41 has a cooling surface and a heating surface. The cooling surface faces the reagent tray 1 and is used to cool the reagent tray 1. The heating surface is attached to the water-cooled heat exchanger 42, and the cooling element 41 can be fixed to the water-cooled heat exchanger 42 by means of screw connection or welding connection, so that the water-cooled heat exchanger 42 dissipates heat from the cooling element 41. The water-cooled heat exchanger 42 is mounted on the mounting bracket 43 by screws. There are two refrigeration assemblies 4 spaced apart in the horizontal direction. It should be noted that the number of refrigeration assemblies 4 can also be one, three, or more, depending on the specific situation.

[0048] Optionally, such as Figures 3-6 As shown, the mounting part 11 is provided with a placement groove, which is inclined relative to the central axis of the reagent tray 1 so that the reagent bottle 2 can be placed tilted in the placement groove.

[0049] Specifically, the mounting component 11 is generally cylindrical. The shape and size of the placement groove are set according to the shape and size of the reagent bottle 2, so that the outer wall of the reagent bottle 2 can fit against the inner wall of the mounting groove, allowing the reagent bottle 2 to be inserted at an angle onto the mounting component 11. The inclination angle of the inner wall of the mounting component 11 is set according to specific circumstances, and this embodiment does not limit it. In other embodiments, the mounting component 11 may also be a clamp that is inclined relative to the vertical direction, with the reagent bottle 2 snapped and fixed to the clamp, so that the reagent bottle 2 is inclined relative to the central axis of the reagent tray 1.

[0050] Optionally, such as Figure 2 and Figure 4 As shown, the mounting component 11 is detachably connected to the reagent tray 1, which facilitates the installation and removal of the mounting component 11. At the same time, mounting components 11 of different sizes can be installed on the reagent tray 1, so that the reagent tray 1 can hold reagent bottles 2 of different sizes.

[0051] Specifically, the bottom of the mounting component 11 has two positioning holes spaced horizontally, and the reagent tray 1 has threaded holes at positions corresponding to the positioning holes. Fastening screws pass through the positioning holes and are threaded into the threaded holes to fix the mounting component 11 onto the reagent tray 1. In other embodiments, the mounting component 11 can also be snapped onto the reagent tray 1; the specific snapping method is described in the prior art and will not be elaborated here.

[0052] In another embodiment, the placement groove is larger than the reagent bottle 2. An arc-shaped positioning block is detachably connected to the inner wall of the placement groove. Part of the outer wall of the reagent bottle 2 fits against the inner wall of the placement groove, and part fits against the positioning block, allowing the reagent bottle 2 to be inserted at an angle onto the mounting component 11. Positioning blocks of different thicknesses can be replaced according to the size of the reagent bottle 2, enabling the mounting component 11 to accommodate reagent bottles 2 of different sizes.

[0053] Optionally, such as Figure 1 and Figure 2 As shown, the drive mechanism 3 includes a motor 31 and a transmission shaft 32. The motor 31 is driven to one end of the transmission shaft 32, and the other end of the transmission shaft 32 is fixedly connected to the side of the reagent tray 1 facing away from the reagent placement area. The motor 31 drives the transmission shaft 32 to rotate, thereby driving the reagent tray 1 to rotate. The transmission shaft 32 is connected to the reagent tray 1. The contact area between the transmission shaft 32 and the reagent tray 1 is small, which avoids excessive low temperature transfer from the reagent tray 1 to the drive mechanism 3. Moreover, this transmission method has a simple and compact structure.

[0054] Specifically, the drive mechanism 3 also includes a motor mounting base 34, a synchronous belt 35, and a synchronous pulley 36. The motor 31 is fixed to the motor mounting base 34 with screws. The synchronous pulley 36 is fixed to the end of the drive shaft 32 away from the reagent tray 1. The synchronous belt 35 connects the output shaft of the motor 31 and the synchronous pulley 36. Through the transmission via the synchronous belt 35 and the synchronous pulley 36, the drive shaft 32 can have a suitable rotational speed. In other embodiments, it can also be driven by the motor 31 and two gears. One gear is installed on the side of the reagent tray 1 facing away from the reagent placement area, and the motor 31 drives the other gear to rotate. The two gears mesh to drive the reagent tray 1 to rotate.

[0055] Furthermore, the drive mechanism 3 also includes a first cold conduction isolation member 33. One side of the first cold conduction isolation member 33 is fixedly connected to one end of the drive shaft 32 facing the reagent tray 1, and the other side is fixedly connected to the reagent tray 1. The first cold conduction isolation member 33 can prevent the low temperature of the reagent tray 1 from being transferred to the drive shaft 32, causing the temperature of the reagent tray 1 to rise. At the same time, it can prevent the low temperature of the drive shaft 32 from generating condensation.

[0056] Specifically, the first cold conduction isolator 33 has a cylindrical structure. The first cold conduction isolator 33 is fixedly connected to the reagent tray 1 and the drive shaft 32 by screws. The material of the first cold conduction isolator 33 can be a material with low thermal conductivity such as plastic or ceramic, and this embodiment does not limit this.

[0057] Optionally, the reagent refrigeration storage device also includes a cold conduction base 5, with the reagent tray 1 positioned above and in clearance fit with the cold conduction base 5, allowing the reagent tray 1 to rotate relative to the cold conduction base 5. A refrigeration component 4 is connected to the side of the cold conduction base 5 facing away from the reagent tray 1. The cold conduction base 5 has mounting holes, through which a drive shaft 32 passes and is fixedly connected to the reagent tray 1. The coldness of the refrigeration component 4 is transferred to the reagent tray 1 via the cold conduction base 5, resulting in a more uniform distribution of coldness to the reagent tray 1, thereby ensuring that each reagent bottle 2 on the reagent tray 1 has a lower temperature.

[0058] Specifically, the cold conduction base 5 is disc-shaped, and its diameter is greater than or equal to that of the reagent tray 1, so that the cold conduction base 5 can cover the bottom of the reagent tray 1 and ensure that the cooling of the reagent tray 1 is more uniform. The fixing bracket 43 is fixed to the side of the cold conduction base 5 facing away from the reagent tray 1 by screws, and the cooling surface of the cooling chip 41 is in contact with the cold conduction base 5.

[0059] Optionally, the reagent refrigeration storage device also includes a sidewall cylinder 10. The sidewall cylinder 10 is cylindrical. It is fitted over the reagent tray 1 and connected to the edge of the cold conduction base 5 by screws. The sidewall cylinder 10 serves to protect the reagent tray 1. The sidewall cylinder 10 is made of metal, giving it a certain strength. A barcode scanning window 101 is provided on the sidewall of the sidewall cylinder 10, allowing the barcode on the reagent bottle 2 inside the sidewall cylinder 10 to be scanned and its information recorded.

[0060] Optionally, the reagent refrigeration storage device further includes a second cold conduction isolation element 6. The first end of the second cold conduction isolation element 6 is connected to the side of the cold conduction chassis 5 facing away from the reagent tray 1, and the second end of the second cold conduction isolation element 6 is connected to the motor 31. The second cold conduction isolation element 6 can prevent the coldness of the cold conduction chassis 5 from being transferred to the motor 31, resulting in less coldness being transferred to the reagent tray 1. At the same time, it can prevent the motor 31 from generating condensate due to its low temperature.

[0061] Specifically, the second cold conduction isolator 6 has a cylindrical structure. Four second cold conduction isolators 6 are provided and extend vertically, arranged in a ring around the output shaft of the motor 31 at intervals. The second end of each second cold conduction isolator 6 is connected to the motor mounting base 34 via a screw, and the first end of each second cold conduction isolator 6 is connected to the side of the cold conduction base 5 facing away from the reagent tray 1 via a screw. The material of the second cold conduction isolator 6 can be a low thermal conductivity material such as plastic or ceramic; this embodiment does not limit this. The number of second cold conduction isolators 6 can also be set according to specific circumstances.

[0062] The reagent cold storage device also includes a heat insulation ring 7, which is installed in the mounting hole. The drive shaft 32 passes through the inner ring of the heat insulation ring 7 and is rotatably connected to the heat insulation ring 7. The heat insulation ring 7 can prevent the cold of the cold conduction chassis 5 from being transferred to the drive shaft 32, resulting in less cold being transferred to the reagent tray 1. At the same time, it can prevent the low temperature of the drive shaft 32 from causing condensation.

[0063] Specifically, the outer wall of the heat insulation ring 7 fits snugly against the mounting hole, and a positioning edge is provided on the side of the heat insulation ring 7 facing the reagent tray 1. The positioning edge is fixed to the cold conduction base 5 by screws. The drive mechanism 3 also includes a bearing 37 and a bearing mounting seat 38. The outer ring of the bearing 37 is mounted on the bearing mounting seat 38. The inner ring of the bearing 37 is interference-fitted onto the drive shaft 32, and the bearing mounting seat 38 is mounted on the inner ring of the heat insulation ring 7. The bearing 37 and the bearing mounting seat 38 enable the rotational connection between the drive shaft 32 and the heat insulation ring 7, while preventing the low temperature of the reagent tray 1 from leaking out through gaps between the heat insulation ring 7 and the drive shaft 32. The material of the heat insulation ring 7 can be a low thermal conductivity material such as plastic or ceramic, which is not limited in this embodiment.

[0064] Optionally, the reagent refrigeration storage device further includes a support assembly 8, which includes a third cold conduction isolator 81 and a support component 82. The first end of the third cold conduction isolator 81 is connected to the side of the cold conduction chassis 5 facing away from the reagent tray 1, and the second end of the third cold conduction isolator 81 is connected to the support component 82. The support component 82 can stably support the cold conduction chassis 5 on the workbench. The third cold conduction isolator 81 can prevent the coldness of the cold conduction chassis 5 from being transferred to the support component 82, resulting in less coldness being transferred to the reagent tray 1. At the same time, it can prevent the support component 82 from having a low temperature and generating condensation.

[0065] Specifically, the support component 82 includes support columns 821 and a base plate 822. Four support columns 821 are provided, all extending vertically, and are arranged in a ring with a central gap relative to the cold conduction chassis 5. One end of each support column 821 is connected to the base plate 822 by screws, and the other end is connected to the side of the cold conduction chassis 5 facing away from the reagent tray 1. The base plate 822 increases the contact area between the reagent refrigeration storage device and the workbench, improving the stability of the reagent refrigeration storage device. The connection between the support columns 821 and the cold conduction chassis 5 reduces the contact area, preventing excessive transfer of cold from the cold conduction chassis 5 to the support component 8, ensuring that more coldness from the cold conduction chassis 5 is transferred to the reagent tray 1. It also prevents the support columns 821 from becoming too cold and generating condensation. Furthermore, it creates an installation space below the cold conduction chassis 5 for mounting the refrigeration component 4 and the motor 31. In other embodiments, the support columns 821 can also be spaced-apart support plates. Both the support column 821 and the base plate 822 are made of metal, which provides good support strength.

[0066] Specifically, the third cold conduction isolator 81 is a cylindrical structure. Multiple third cold conduction isolators 81 extend vertically, and each third cold conduction isolator 81 corresponds to a support column 821. The second end of each third cold conduction isolator 81 is connected to the end of the support column 821 facing the cold conduction base 5 via a screw. The first end of each third cold conduction isolator 81 is connected to the side of the cold conduction base 5 facing away from the reagent tray 1 via a screw. The material of the third cold conduction isolator 81 can be a low thermal conductivity material such as plastic or ceramic; this embodiment does not limit this.

[0067] Optionally, the reagent cold storage device also includes a heat preservation component 9, which is disposed on the side and bottom of the reagent tray 1. The heat preservation component 9 can keep the reagent tray 1 warm, so that the reagent tray 1 can maintain a low temperature, while preventing the reagent tray 1 from coming into contact with high external temperatures and generating condensation.

[0068] Specifically, the insulation component 9 includes a first insulation element 91 and a second insulation element 92. The first insulation element 91 is cylindrical, fitted onto the outside of the sidewall cylinder 10, and bonded to the sidewall cylinder 10. The second insulation element 92 is a circular sheet structure, the same size as the cold conduction base 5, and bonded to the side of the cold conduction base 5 facing away from the reagent tray 1. The second insulation element 92 can simultaneously insulate both the reagent tray 1 and the cold conduction base 5. The second insulation element 92 is provided with multiple clearance holes to avoid the refrigeration component 4, the second cold conduction isolation element 6, and the third cold conduction isolation element 81. The first insulation element 91 and the second insulation element 92 can be made of insulation cotton. In this embodiment, both the first insulation element 91 and the second insulation element 92 are made of double-layer EVA insulation cotton, which has a better insulation effect.

[0069] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
