Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a reagent card incubation tray suitable for use in medical in vitro diagnostic equipment. Background Technology

[0002] An in vitro diagnostic analyzer is an instrument that performs quantitative or qualitative analysis on a patient's bodily fluid samples. This analyzer includes an incubation mechanism for incubating reagent cards during the diagnostic analysis process. The incubation mechanism includes an incubation tray. Traditional incubation trays have inaccurate positioning of the reagent card by the limiting devices on both sides of the incubation position. Specifically, some limiting devices have large contact surfaces and small gaps on both sides, resulting in high frictional resistance and hindering the reagent card from entering the incubation tray; others have gaps that are too large, leading to inaccurate positioning of the reagent card during incubation and making it difficult for the card to exit the incubation tray. Furthermore, traditional reagent card turntables and incubation are separate processes, resulting in poor incubation efficiency.

[0003] Chinese utility model patent CN202022339004.6 discloses a reagent card and a reagent card fixing device. This patent improves the structure of both traditional reagent cards and reagent card fixing devices. The improved positioning method uses the elastic deformation of an elastic sheet to generate continuous downward pressure, ensuring a tight fit between the reagent card and the bottom of the tank. However, after long-term use, the elastic sheet may experience elastic decay or plastic deformation, leading to a decrease in holding force and affecting the positioning effect. Therefore, existing reagent card incubation fixing devices still have certain shortcomings, and it is necessary to propose a new technical solution to solve the problems existing in the prior art. Utility Model Content

[0004] This application provides an incubation tray suitable for reagent cards, which enables smooth, low-resistance pushing and stable positioning of reagent cards.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] An incubation tray for reagent cards includes an incubation tray body. A plurality of incubation slots for placing reagent cards are evenly distributed along the lower edge of the incubation tray body. The length direction of each incubation slot is the same as the radial direction of the incubation tray body. A limiting boss is formed between any two adjacent incubation slots. Two limiting ball structures are spaced apart along the radial direction of the incubation tray body on the sidewall of each limiting boss, adjacent to the sidewall of the incubation slot. Each limiting ball structure includes a limiting ball hole formed on the sidewall of the limiting boss and a limiting ball disposed within the limiting ball hole. A limiting plate is provided on the bottom plane of each limiting boss. The two sides of the limiting plate extend to the bottom of two adjacent incubation slots. Any two adjacent limiting bosses limit the reagent card placed between them through the limiting ball and the limiting plate.

[0007] Furthermore, in the above technical solution, the lower surface of the incubation tray body forms an inner ring ejection groove for holding the ejection pin, and a plurality of incubation grooves are equally spaced around the inner ring ejection groove, and an ejection groove is formed between the inner ring ejection groove and the incubation groove to allow the ejection pin to pass through.

[0008] Furthermore, the incubation tank forms the reagent card inlet at one end of the edge of the incubation tray body. Two limiting balls on two adjacent limiting protrusions that are close to the inlet of the incubation tank constitute the first set of limiting balls, and two limiting balls on two adjacent limiting protrusions that are far from the inlet of the incubation tank constitute the second set of limiting balls. Each set of limiting balls can make point contact with both sides of the reagent card inserted into the incubation tank and roll to assist the reagent card in moving forward.

[0009] Furthermore, the size of the limiting ball is adapted to the size of the limiting ball hole, and the limiting ball can rotate relative to the limiting ball hole under the action of external force. The rolling clearance between the first set of limiting balls and the limiting ball hole is smaller than the rolling clearance between the second set of limiting balls and the limiting ball hole.

[0010] Furthermore, a heating film and a temperature sensor mounting slot are provided on the upper surface of the incubation tray body. A temperature measuring through hole is opened in the temperature sensor mounting slot. The temperature measuring through hole is located at the reagent incubation part of the reagent card. The temperature sensor placed in the temperature sensor mounting slot is used to detect the incubation temperature of the reagent card.

[0011] Furthermore, the lower surface of the incubation tray body has 24 incubation slots evenly distributed around its circumference.

[0012] Furthermore, the limiting boss has a chamfer at one end of its side wall adjacent to the incubation tank. The chamfer is located at the edge of the incubation tray body, and the chamfers on both sides of the incubation tank form the inlet of the incubation tank.

[0013] Compared with the prior art, this application has at least the following beneficial effects:

[0014] 1. This application places the incubation tank on the lower surface of the incubation tray body, which can prevent dust accumulation in the incubation tank and improve the smoothness of reagent card insertion. In addition, two limiting ball structures are arranged at intervals along the radial direction of the incubation tray body on both sides of the incubation tank, and the limiting plate on the limiting protrusion extends to the bottom of the two adjacent incubation tanks. The limiting plate and the limiting ball can limit the reagent card in the incubation tank. At the same time, the limiting ball structure can make point contact with the two sides of the reagent card during the insertion of the reagent card and roll to assist the reagent card to move forward. Therefore, this application can achieve low-resistance rolling assistance and limiting of the reagent card through the limiting ball, improving the smoothness of reagent card insertion. In addition, the limiting ball structure has a certain degree of fault tolerance. Even if the reagent card is slightly tilted during the insertion process, it can still be inserted smoothly. When the incubation tray rotates, it works with the limiting plate to stably position the reagent card to prevent the reagent card from falling out.

[0015] 2. The lower surface of the incubation tray is provided with an inner ring card ejection groove for holding the ejection needle. The incubation tank is located outside the inner ring card ejection groove, which makes high space utilization. The design of the card ejection needle holding position and ejection groove on the incubation tray facilitates the ejection of the reagent card after the incubation is completed.

[0016] 3. The inlet of the incubation tank is located at the edge of the incubation tray body for easy sample addition.

[0017] 4. Two sets of limiting rollers are installed on the walls of the incubation tank. The first set of limiting rollers is close to the inlet, and the second set is far from the inlet. When the reagent card is pushed into the incubation tank, there is enough gap on both sides to ensure that the reagent card can enter the incubation tank. The sides of the incubation tank make point contact with the first set of limiting rollers. The limiting rollers roll the reagent card forward with very little resistance. At this time, although the front part of the reagent card has entered the incubation tank and is initially limited, the rear part of the reagent card is still in the slot of the upper card carriage. Even if the slot on the carriage is not completely aligned with the target incubation tank and the reagent card is slightly tilted to the left or right, it will not affect the loading of the reagent card. When the reagent card moves forward to the second set of limiting rollers, the rear part of the reagent card is completely disengaged from the slot of the upper card carriage. At the same time, the frictional resistance of the two sets of limiting rollers rolling the reagent card is very small, and the reagent card can smoothly enter the incubation tank. After the reagent card is in place, the limiting rollers on both sides hold the reagent card and cooperate with the limiting plate to achieve stable positioning of the reagent card and prevent the reagent card from falling off when the turntable rotates.

[0018] 5. The rolling clearance between the first set of limiting balls and the limiting ball holes is smaller than that between the second set of limiting balls and the limiting ball holes. That is, the second set of limiting balls in the incubation tank is slightly tighter than the first set of limiting balls. This ensures convenient card insertion and prevents reagent card displacement. In addition, the limiting balls on both sides of the incubation tank can be installed by limiting plates on both sides. The ball limiting structure is simple, the contact resistance at the rolling point is small, and its installation is easy.

[0019] 6. This application provides a heating film and a temperature sensor mounting slot on the upper surface of the incubation tray body. The heating film can provide a constant temperature environment for incubation. In order to detect the appropriate working temperature of the reagent card during incubation at all times, a temperature measuring hole is provided in the temperature sensor mounting slot. The temperature measuring hole is located at the reagent incubation part of the reagent card. The temperature sensor placed in the temperature sensor mounting slot can promptly and accurately reflect the incubation temperature of the reagent card.

[0020] 7. The incubation tray provided in this application has a simple structure and is easy to install and use. The needle removal card holder and needle removal groove designed on it not only facilitate the removal of reagent cards, but also reduce the weight of the incubation tray and the loss of incubation heat.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "including," "comprising," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0031] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to facilitate intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationships in the actual product. Changes in these relative positional relationships, without departing from the technical concept disclosed in this application, should also be considered within the scope of this application.

[0032] This application provides an incubation tray suitable for reagent cards, see [link to relevant documentation]. Figure 1 , 2 The incubation tray includes an incubation tray body 1. A plurality of incubation grooves 2 for placing reagent cards 7 are evenly distributed along the lower edge of the incubation tray body 1. The length direction of the incubation grooves 2 is the same as the radial direction of the incubation tray body 1. A limiting boss is formed between any two adjacent incubation grooves 2. Two limiting ball bearing structures are spaced back-to-back along the radial direction of the incubation tray body 1 on the side wall of the limiting boss, adjacent to the incubation groove 2. Figure 4 The limiting ball structure includes a limiting ball hole 6 formed on the side wall of the limiting boss and limiting balls disposed within the limiting ball hole 6. For example... Figure 2 , 5 Each limiting protrusion has a limiting plate 8 on its bottom plane. The two sides of the limiting plate 8 extend to the bottom of two adjacent incubation tanks 2 respectively. Any two adjacent limiting protrusions limit the reagent card 7 placed between them through the limiting ball and the limiting plate 8.

[0033] First, this application provides two limiting ball structures spaced back and forth along the radial direction of the incubation tray body 1 on both sides of the incubation tank 2. The limiting plate 8 on the limiting protrusion extends to the bottom of the two adjacent incubation tanks 2 on both sides. The limiting plate 8 and the limiting ball structures can limit the reagent card 7 within the incubation tank 2. Second, the limiting ball structures can make point contact with both sides of the reagent card 7 during insertion and roll to assist the reagent card 7 in advancing. Therefore, this application can achieve low-resistance rolling assistance and limiting of the reagent card 7 through the limiting ball structures, improving the smoothness of reagent card insertion. Furthermore, the limiting ball structures have a certain degree of fault tolerance; even if the reagent card 7 is slightly tilted during insertion, it can still be inserted smoothly. When the incubation tray rotates, it works with the limiting plate 8 to stably position the reagent card 7 and prevent it from falling out. Moreover, this application places the incubation tank 2 on the lower surface of the incubation tray body 1, which can prevent dust accumulation in the incubation tank 2 and improve the smoothness of reagent card insertion.

[0034] In a preferred embodiment of this application, the incubation tank 2 forms an inlet 9 for the reagent card 7 at one end of the edge of the incubation tray body 1. Two limiting balls on two adjacent limiting protrusions near the inlet 9 of the incubation tank 2 constitute a first set of limiting balls 10. Two limiting balls on two adjacent limiting protrusions away from the inlet 9 of the incubation tank 2 constitute a second set of limiting balls 11. Each set of limiting balls can make point contact with both sides of the reagent card 7 inserted into the incubation tank 2 and roll to assist the reagent card 7 in advancing.

[0035] This application places the inlet 9 of the incubation tank 2 at the edge of the incubation tray body 1 for easy sample addition. Furthermore, the first set of limiting rollers 10 are close to the inlet 9, and the second set of limiting rollers 11 are far from the inlet 9. When the reagent card 7 is pushed into the incubation tank 2, there is sufficient gap on both sides to ensure that the reagent card 7 can enter the incubation tank 2. The two sides of the incubation tank 2 make point contact with the first set of limiting rollers 10, and the limiting rollers roll the reagent card 7 with very little resistance. At this time, although the front of the reagent card 7 has entered the incubation tank 2 for initial limiting, the rear of the reagent card 7 is still in the slot of the upper card carriage. Even if the slot on the carriage is not in contact with the target incubation tank 2... Even if the reagent card 7 is not fully aligned and is slightly tilted to the left or right, it will not affect the loading of the reagent card 7. When the reagent card 7 moves forward to the second set of limiting balls 11, the rear of the reagent card 7 is completely disengaged from the loading trolley slot. At the same time, the frictional resistance of the two sets of limiting balls rolling the reagent card 7 is very small, and the reagent card 7 can smoothly enter the incubation tank 2. After the reagent card 7 is in place, the limiting balls on both sides hold the reagent card 7 and work with the limiting plate 8 to achieve stable positioning of the reagent card 7, preventing the reagent card 7 from falling off when the turntable rotates.

[0036] In a preferred embodiment of this application, the size of the limiting ball is adapted to the size of the limiting ball hole 6, and the limiting ball can rotate relative to the limiting ball hole 6 under the action of external force. The rolling clearance between the first set of limiting balls 10 and the limiting ball hole 6 is smaller than the rolling clearance between the second set of limiting balls 11 and the limiting ball hole 6. That is, the second set of limiting balls 11 in the incubation tank 2 is slightly tighter than the first set of limiting balls 10, thus ensuring convenient card insertion and preventing reagent card 7 from shifting. Furthermore, the limiting balls on both sides of the incubation tank 2 can be fixed by the limiting plates 8 on both sides. This ball limiting structure is simple, has low contact resistance at the rolling point, and is easy to install.

[0037] In a preferred embodiment of this application, the lower surface of the incubation tray body 1 forms an inner ring card ejection groove for holding the ejection pin. A plurality of incubation grooves 2 are evenly distributed around the inner ring card ejection groove, and a ejection pin groove 5 is formed between the inner ring card ejection groove and the incubation grooves 2 to allow the ejection pin to pass through. Therefore, the incubation tray provided by this application facilitates the ejection of the reagent card 7 after incubation. Furthermore, by placing the incubation grooves 2 around the inner ring card ejection groove, space utilization is high.

[0038] In a preferred embodiment of this application, such as Figure 3 This application provides a heating film mounting surface 13 and a temperature sensor mounting slot 12 on the upper surface of the incubation tray body 1. The heating film provides a constant temperature environment for incubation. To continuously monitor the appropriate operating temperature of the reagent card 7 during incubation, a temperature measuring hole 3 is provided in the temperature sensor mounting slot 12. The temperature measuring hole 3 is located at the reagent incubation part of the reagent card 7, and the temperature sensor placed in the temperature sensor mounting slot 12 can promptly and accurately reflect the incubation temperature of the reagent card 7.

[0039] In a preferred embodiment of this application, 24 incubation grooves 2 are evenly distributed around the lower surface of the incubation tray body 1, and a heating film mounting surface 13 is formed on the upper surface of the incubation tray body 1. Therefore, the incubation tray can incubate at the top and limit the sample addition at the bottom, and can perform direct incubation while the incubation tray is rotating, which greatly improves the incubation efficiency.

[0040] In a preferred embodiment of this application, a chamfer is provided at one end of the limiting boss close to the side wall of the incubation tank 2. The chamfer is located at the edge of the incubation tray body 1. The chamfers on both sides of the incubation tank 2 form the inlet 9 of the incubation tank 2. The inlet 9 is funnel-shaped to facilitate the entry of the reagent card 7.

[0041] This application features 24 incubation slots 2 evenly distributed around the circumference of the lower surface of the incubation tray, significantly improving incubation efficiency. The use of a bottom-mounted and retractable card design saves space, resulting in a more rational and compact structure. The incubation slots 2 are designed on the lower surface of the incubation tray, with the upper surface forming a heating film mounting surface. The heating film mounting surface, covered with a heating film, directly provides a constant temperature environment for incubation. A temperature sensor is also installed on the upper surface, directly detecting the temperature of the reagent incubation area of ​​the reagent card through a temperature sensing through-hole. The reagent card 7 is positioned on both sides by two limiting ball holes 6 located on both sides of the incubation slot 2 and limiting balls installed within these holes 6. Figure 4 The diagram shows the first set of limiting balls 10 and the second set of limiting balls 11. When the reagent card 7 enters the incubation tank 2, the incubation tank entrance is designed with a chamfer, which forms an inlet 9. The design of the inlet 9 facilitates the introduction of the reagent card into the incubation tank 2. In a specific application example, sufficient gaps are left on both sides of the incubation tank 2 to ensure the entry of the reagent card 7. The two sides of the incubation tank 2 are in point contact with the balls on both sides of the first set of limiting balls 10. The resistance to the forward movement of the reagent card 7 is very small. At this time, although the front part of the reagent card 7 has entered the incubation tank 2 and is initially limited, the rear part of the reagent card 7 is still in the slot of the upper card carriage. Even if the slot of the carriage and the target incubation tank are not completely aligned, and the reagent card 7 is slightly tilted to the left and right, it will not affect the reagent card 7 from continuing to enter the incubation tank 2.

[0042] When reagent card 7 moves forward to the balls on both sides of the second set of limiting balls 11, the rear of reagent card 7 is completely disengaged from the upper card tray slot. The rolling of the first set of limiting balls 10 and the second set of limiting balls 11 reduces frictional resistance, allowing reagent card 7 to smoothly enter the incubation tank 2. Then, the first set of limiting balls 10 and the second set of limiting balls 11 hold reagent card 7 in place, preventing it from falling off when the incubation tray rotates. The rolling gap (or rolling friction) of the second set of limiting balls 11 is slightly smaller than that of the first set of limiting balls 10, which ensures that reagent card 7 can easily enter the incubation tank 2 while preventing it from shifting.

[0043] In this application, the first set of limiting balls 10 and the second set of limiting balls 11 in the incubation tank 2 can be installed by limiting plates 8 on both sides. The rolling ball limiting structure is simple, with low contact resistance at the rolling point, making it easy to install. Meanwhile, the incubation tray is designed with a card ejection pin stop 4 and a card ejection groove 5, which facilitates the ejection of the reagent card 7 after incubation. Furthermore, the incubation tray provided in this application has a reasonable overall structural layout, employing direct heating from the top of the incubation tray, which is beneficial to the incubation environment of the reagent card 7. When the incubation tray is working, it can provide 24 incubation positions simultaneously, significantly improving incubation efficiency.

[0044] In summary, this application provides an incubation tray suitable for reagent cards. The incubation tray has 24 incubation slots evenly distributed around its circumference. These slots are located on the lower surface of the tray, while the upper surface is covered with a heating film to provide a constant temperature environment for incubation. A temperature sensor mounting slot is designed on the top of the incubation tray, with a through hole at one end of the slot. This through hole is precisely located at the reagent incubation area of ​​the reagent card, allowing the temperature sensor to accurately and promptly reflect the incubation temperature. The reagent card is controlled by two rolling ball bearings on either side of the incubation slots, divided into a first group and a second group. The ball bearings make point contact with the reagent card, and their rolling motion minimizes frictional resistance as the reagent card moves forward. The ball bearings on both sides of the incubation slots are further controlled by limiting plates on both sides. The overall structure of the incubation tray is simple, easy to install and use, and the ball bearing limiting structure enables smooth, low-resistance pushing and stable positioning of the reagent card.

[0045] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0046] The present application has been described in a relatively specific and detailed manner above through general descriptions and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
