Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a heating device and an analyzer. Background Technology

[0002] The analyzer testing process includes a reagent addition step. After adding the substrate solution (a type of reagent), the sample-reagent mixture needs to be incubated at 37°C. Since the substrate solution is refrigerated or stored at room temperature before use, preheating the substrate solution can shorten the incubation time, facilitate the interaction of the substrate solution with the magnetic bead binding material, improve reactivity and stability, and reduce the influence of ambient temperature on the experiment.

[0003] Existing preheating solutions typically involve installing a heating device at the injection port. This device generally includes a base and a heating source located at the bottom of the base. Heat is transferred from the heating source through the bottom of the base to the injection pipe located on the base, thereby preheating the substrate liquid inside the injection pipe.

[0004] However, regarding the above preheating scheme, firstly, the reagent addition process generally uses plastic tubes for direct injection or a coated metal needle for injection. Direct use of metal needles is generally avoided to prevent the reagent components from reacting with the metal material and damaging the reagent composition. Plastic tubes are more commonly used because they are more economical; that is, the injection tubes are mostly made of plastic. However, plastic injection tubes have low thermal conductivity and are not suitable for direct heating by heating devices, which can easily lead to deformation and damage. Secondly, the above preheating scheme uses a heating source located at the bottom of the base to heat the injection tubes on the base. For high-throughput equipment with high reagent demand, this method has low heat exchange efficiency, making it difficult to inject the substrate liquid that meets the temperature requirements in a short time (tens of seconds or even a few seconds). To meet the needs of high-throughput equipment, the heat exchange area of ​​the base or the input power of the heating source must be increased, which leads to structural complexity, larger volume, and higher requirements for control precision due to the increased input power of the heating source. Utility Model Content

[0078] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0079] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0080] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0081] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0082] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0083] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0084] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0085] This application provides a heating device 100 and an analyzer using the heating device 100 for heating reagents inside the analyzer.

[0086] like Figures 1 to 9As shown, the heating device 100 provided in this application embodiment includes a housing 10 and a heating part located inside the housing 10. The heating part includes a heating base 20, a heating source disposed on opposite sides of the heating base 20 (such as the third side wall 23 and the fourth side wall 24 of the heating base 20), and a heating pipe 30 having an inlet 31 and an outlet 32. The top and bottom surfaces of the heating base 20 are provided with multiple channels, which can be multiple upper channels 251 and multiple lower channels 252, respectively. The heating pipe 30 is disposed in the multiple channels, and the inlet 31 and outlet 32 ​​of the heating pipe 30 extend out of the housing 10.

[0087] Compared with the prior art, the heating device 100 provided in this application embodiment allows the substrate liquid that needs to be preheated to enter the heating pipe 30 through the inlet 31 extending outside the housing 10. The heat from the heating source is transferred to the heating pipe 30 through the heating base 20 for heating, and then flows out through the outlet 32 ​​extending outside the housing 10, completing the heating process. This will not damage the injection pipe used in the system, thus ensuring the safe use of the injection pipe. Furthermore, the heating source (such as a heating film) provided in this application embodiment is disposed on opposite sides of the heating base 20 (such as the third side wall 23 and the fourth side wall 24 of the heating base 20), and the heating base 20... Multiple channels for placing heating pipes 30 are provided on both the top and bottom surfaces of the heating source. This side arrangement of the heating source and the arrangement of multiple channels on both the top and bottom surfaces of the heating base 20 greatly increases the heat exchange area between the heating pipes 30 and the heating base 20, further ensuring the heat exchange effect and meeting the needs of high-throughput equipment. Moreover, the overall structure is compact, without increasing the volume occupied or causing structural complexity. Furthermore, the two heating sources are symmetrically arranged on opposite sides of the heating base, which can further ensure the uniformity of the heating temperature of the heating base. At the same time, increasing the input power of the heating source does not require further improvement in the control precision of the heating source.

[0088] A further embodiment is, as follows: Figure 2 and Figures 5 to 9 As shown, the aforementioned heating pipe 30 may specifically include a bend section 34 and a straight pipe section 33 connected to the bend section 34. The two ends of the heating pipe 30 are an inlet 31 and an outlet 32, respectively. By using this heating pipe with multiple sections such as the bend section 34 and the straight pipe section 33 connected and arranged in a loop, the heating meandering path of the substrate liquid within the heating device 100 can be increased, the capacity of the substrate liquid that can be preheated simultaneously can be increased, further meeting the needs of high-flow equipment, increasing the heat exchange area, and improving preheating efficiency.

[0089] Furthermore, the heating pipe 30 provided in this embodiment does not use the plastic material commonly used in traditional injection pipes, because plastic material has a low thermal conductivity and is not suitable for direct addition, which can easily lead to pipe deformation and damage during heating. The heating pipe 30 provided in this embodiment uses a heat-resistant and thermally conductive non-metallic pipe. Specifically, the straight pipe section 33 can use a rigid non-metallic pipe with a high thermal conductivity, such as a glass pipe, while the bent pipe section 34 can use a soft non-metallic pipe.

[0090] This design offers several advantages: First, it not only provides heat resistance but also boasts high thermal conductivity, resulting in excellent heating performance and rapid heating speed. Second, the use of non-metallic materials prevents the substrate liquid from reacting with metallic materials and damaging the reagent components, thus ensuring the integrity of the substrate liquid. Third, the flexible non-metallic material of the bent tube section 34 facilitates bending and connection, saves internal space, creates a more compact structure, and enhances heat exchange efficiency.

[0091] In a preferred embodiment, the aforementioned heating base 20 can be a metal heating base 20. Metal conducts heat quickly, and using a metal heating base to directly heat the heating pipe 30 greatly enhances the heat exchange efficiency. It can preheat the substrate liquid that meets the temperature requirements in a short time (tens of seconds or even a few seconds), which greatly satisfies the heat exchange needs.

[0092] Another preferred embodiment is that, in order to improve the utilization rate of the internal heating space of the heating seat 20 and improve the heating efficiency, the channel of the heating seat can be divided into two layers, the top and the bottom.

[0093] Specifically, such as Figures 2 to 5 As shown, the heating base 20 may include a heating base body 25 and a first pipe passage space 261 and a second pipe passage space 262 located on opposite sides of the heating base body 25. The first pipe passage space 261 and the second pipe passage space 262 are used to house the aforementioned heating pipe 30 bent pipe sections 34. The top and bottom surfaces of the heating base body 25 may each have multiple bends along the... Figure 3 The upper channel 251 and lower channel 252, extending in the first direction a and arranged parallel to each other, are used to place the straight pipe sections 33 of the aforementioned heating pipes 30 one-to-one. The heating base 20 has heating sources attached to its opposite sides (third sidewall 23 and fourth sidewall 24) along a second direction b perpendicular to the first direction a. Specifically, these heating sources can be heating films, namely a first heating film 231 and a second heating film 241. Such heating sources are easy to control and the overall module setup is simple. This configuration improves the utilization rate of the internal heating space of the heating base 20 and increases heating efficiency. Furthermore, when the input power of the heating source is increased, due to the increased transmission distance between the heating source and the heating pipes 30 and the large heat capacity of the heating base 20, there is no need to further improve the control precision of the heating source.

[0094] Furthermore, such as Figures 3 to 5As shown, both the upper channel 251 and the lower channel 252 can be concave structures, such as the upper channel 251 which is concave downwards and the lower channel 252 which is concave upwards. They can also be tubular hole structures set in the main body of the heating base 20. The straight pipe section 33 can be placed in it or embedded in it, as long as the straight pipe section 33 can be set on the heating base 20 and can be connected to the bent pipe section 34.

[0095] Specifically, the heating seat 20 has a first sidewall 21 and a second sidewall 22 on opposite sides along the first direction a, and a third sidewall 23 and a fourth sidewall 24 on opposite sides along the second direction b. The first passage space 261 has a first main sidewall of the heating seat body 25 and a first sidewall 21 of the heating seat 20 on opposite sides along the first direction a; the second passage space 262 has a second main sidewall of the heating seat body 25 and a second sidewall 22 of the heating seat 20 on opposite sides along the first direction a; the first sidewall 21 and the second sidewall 22 of the heating seat 20 are respectively provided with an inlet and an outlet, which are respectively provided with the liquid inlet 31 and the liquid outlet 32 ​​of the heating pipe 30.

[0096] In one specific embodiment, two heating pipes 30 may be provided, namely a first heating pipe 35 and a second heating pipe 36. The top and bottom of the first side wall 21 of the heating base 20 near the third side wall 23 may be provided with an upper inlet 211 and a lower inlet 212, respectively, corresponding to the first liquid inlet 311 and the second liquid inlet 312 of the two heating pipes 30 (the first heating pipe 35 and the second heating pipe 36). The top and bottom of the second side wall 22 of the heating base 20 near the fourth side wall 24 may be provided with an upper outlet 221 and a lower outlet 222, respectively, corresponding to the first liquid outlet 321 and the second liquid outlet 322 of the two heating pipes 30 (the first heating pipe 35 and the second heating pipe 36).

[0097] In one optional embodiment, the two heating pipes 30 are respectively located on the top and bottom surfaces of the heating base 20, i.e., they are set separately, with one heating pipe 30 on the upper side of the heating base 20 and the other heating pipe 30 on the lower side of the heating base 20.

[0098] Another alternative embodiment is that the straight pipe sections 33 and the bend sections 34 of the two heating pipes 30 are arranged in an alternating manner, such as... Figures 3 to 9 As shown, this application uses this optional embodiment as an example for illustration. Because the distance between the straight pipe sections 33 in the upper and lower layers is small, it is necessary to avoid the problem of pipe bending caused by the small turning radius of the bend pipe section 34. This staggered connection method between the upper and lower layers and the cross arrangement of the two heating pipes 30 are adopted to ensure that the pipes do not bend due to the distance.

[0099] Specifically, each upper channel 251 is arranged at intervals along the second direction b, and multiple first upper straight pipe sections 351 of the first heating pipe 35 and multiple second upper straight pipe sections 361 of the second heating pipe 36 are arranged alternately in each upper channel 251; each lower channel 252 is arranged at intervals along the second direction b, and multiple second lower straight pipe sections 362 of the second heating pipe 36 and multiple first lower straight pipe sections 352 of the first heating pipe 35 are arranged alternately in each lower channel 252.

[0100] Furthermore, the upper and lower channels 251 and 252 on the same longitudinal direction c are equipped with straight pipe sections 33 of different heating pipes 30. For example, if the upper channel 251 on the same longitudinal direction c is equipped with the first upper straight pipe section 351, then the lower channel 252 below is equipped with the second lower straight pipe section 362. If the upper channel 251 on the same longitudinal direction c is equipped with the second upper straight pipe section 361, then the lower channel 252 below is equipped with the first lower straight pipe section 352.

[0101] Furthermore, each bend 34 of the same heating pipe 30 sequentially connects the ends of the upper and lower straight pipe sections 33 of two adjacent heating pipes 30 along the second direction b. The two adjacent bend 34 on the same side are arranged in a staggered manner. For example, if one end of a bend 34 is connected to the first upper straight pipe section 351, then its other end is connected to the first lower straight pipe section 352. If one end of a bend 34 is connected to the second upper straight pipe section 361, then its other end is connected to the second lower straight pipe section 362.

[0102] An alternative embodiment is, as in 3 and Figure 4 As shown, both the aforementioned first pipe passage space 261 and second pipe passage space 262 can include a clearance cavity 27. The top of the clearance cavity 27 is lower than the bottom of the upper channel 251, and the bottom of the clearance cavity 27 is higher than the top of the lower channel 252. The lateral width of both the first pipe passage space 261 and the second pipe passage space 262 along the first direction a is less than or equal to twice the diameter of the bend section 34. This ensures both installation and contact between the bend section 34 and the heating base body 25.

[0103] A further embodiment is, as Figure 2 and Figure 5 As shown, the top and bottom of the heating base 20 may be provided with an upper sealing plate 41 and a lower sealing plate 42, respectively, to press down the heating pipes 30 arranged in the channels on the top and bottom surfaces of the heating base 20. Specifically, the upper sealing plate 41 may be a metal sealing plate made of metal material. Considering that the heating device 100 needs to be installed and fixed with external parts, in order to prevent the heat inside the heating device 100 from being conducted from the mounting ear 14 to other metal parts or the air, the lower sealing plate 42 is preferably made of plastic material, which can both ensure structural rigidity and reduce external heat conduction.

[0104] Another further embodiment is, as follows: Figure 2 and Figure 5 As shown, the housing 10 may include an upper insulation cotton 11 at the top, a lower insulation cotton 12 at the bottom, and side insulation cotton 13 arranged around the sides. The upper insulation cotton 11, side insulation cotton 13, and lower insulation cotton 12 wrap the entire heating element to form an insulation layer, preventing the heating element from exchanging heat with the outside environment.

[0105] An alternative embodiment is, as follows: Figures 2 to 4 As shown, a temperature sensor 51 can be embedded in the third side wall 23 or the fourth side wall 24 of the heating base 20. The temperature sensor 51 is electrically connected to the host computer, and the host computer is electrically connected to the heating source for control. Furthermore, a temperature fuse 61 can be embedded in the same side wall of the heating base 20 as the one with the temperature sensor 51. The temperature fuse 61 is in contact with the heating source. When the temperature of the heating source is too high, exceeding the preset high temperature value, the temperature fuse 61 automatically disconnects to cut off the power supply. Correspondingly, a sensor mounting hole 52 and a fuse box mounting groove 62 are also provided at the corresponding positions of the third side wall 23 or the fourth side wall 24 of the heating base 20. In addition, as... Figure 1 As shown, the enclosure 10 may also include a power cord 15, a communication cable, mounting ears 14, etc.

[0106] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
