Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a disc-type incubation device. Background Art

[0002] The test process of a fully automatic immunoassay analyzer includes steps such as loading the reaction cup, adding reagents, adding samples (dilution of the sample is required if necessary), incubation, washing, incubation, and interpretation. Incubation provides a stable temperature environment (such as 37°C) for the reaction solution to react. The temperature directly affects the reaction effect of the reaction solution, and the stability of the temperature determines the quality of the experiment. Therefore, an incubation device with a stable temperature that is not affected by external temperature directly determines the performance of the instrument.

[0003] Existing incubation devices have windows on the top cover for entering and exiting reagents, and a heating film and insulation board are installed at the lower end of the incubation tray and the lower surface of the top cover. When heating the incubation tray with this heating method, the heat from the heating film needs to be transferred to the incubation tray through the air. Because the thermal conductivity of air is low, the preheating time of this incubation device is relatively long. In addition, due to the windows on the top cover, the internal temperature of the incubation device is easily affected by external temperature fluctuations, resulting in significant fluctuations. The more windows there are, the greater the impact of external temperature. Utility Model Content

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0036] See also Figures 1 to 6 , this embodiment provides a disc-type incubation device, including an incubation seat assembly 1, an incubation disc assembly 2 and an incubation drive assembly 3.

[0037] The incubation seat assembly 1 includes an incubation seat 11 and an upper cover 12 arranged on the incubation seat 11 . The upper cover 12 is provided with a cup inlet and outlet window 121 , and the cup inlet and outlet window 121 is communicated with the interior of the incubation seat 11 .

[0038] The incubation tray assembly 2 is arranged in the incubation seat 11. The incubation tray assembly 2 includes an incubation tray 21, a turntable heating element 22 and a circuit board 23 arranged from bottom to top. A plurality of reaction cup placement holes 211 are provided on the incubation tray 21, and the plurality of reaction cup placement holes 211 are evenly arranged along the circumference of the incubation tray 21 to form a circle on the incubation tray 21, and the outer diameter of the circle is slightly smaller than the outer diameter of the incubation tray 21. The incubation tray 21 can rotate around its own axis, so that the plurality of reaction cup placement holes 211 can be arranged in correspondence with and connected to the cup entry and exit window 121 in sequence, so that the staff can conveniently put the reaction cup 4 into or take out the reaction cup placement hole 211 through the cup entry and exit window 121.

[0039] The turntable heater 22 is mounted on the top wall of the incubation tray 21 and engages with it for heat transfer. Specifically, the turntable heater 22 is positioned within the circle and fills the entire inner space, maximizing the area of the turntable heater 22 and, consequently, the contact area between the turntable heater 22 and the incubation tray 21. This increases the speed of heat transfer and shortens the preheating time of the incubation tray 21. Furthermore, the distance from the edge of the turntable heater 22 to each cuvette placement hole 211 is substantially equal, ensuring that the amount of heat transferred to each cuvette placement hole 211 is essentially consistent.

[0040] Since the cup access window 121 is always open, the heat inside the incubation seat 11 and the cold air outside the incubation seat 11 can be transferred through the cup access window 121, resulting in the temperature change outside the incubation seat 11 affecting the ambient temperature inside the incubation seat 11. Therefore, the turntable heating element 22 of this embodiment is arranged near the cup access window 121. Part of the heat emitted by the turntable heating element 22 is transferred to the incubation tray 21, and part is used to offset the impact of the external ambient temperature change, ensuring that the temperature of the incubation tray 21 can be stabilized within a first preset threshold value, which can be set according to actual needs.

[0041] The turntable heating element 22 is a component that can convert electrical energy into heat energy and dissipate it outwards, including a heating film, a heating wire, etc. In this embodiment, the heating film is preferably used.

[0042] The incubation drive assembly 3 is disposed outside the incubation seat 11. One end of the incubation drive assembly 3 extends into the incubation seat 11 and connects to the incubation tray assembly 2, driving the rotation of the incubation tray 21. The incubation tray 21 can rotate and stop at a preset rotation angle, so that each time it stops, the cup access window 121 can correspond to and communicate with one of the reaction cup placement holes 211, making it convenient to insert or remove the reaction cup 4.

[0043] See also Figures 5 to 7Three first temperature sensors 24 are provided on the incubation tray 21. The three first temperature sensors 24 are evenly distributed along the circumference of the incubation tray 21 and are locked to the lower part of the incubation tray 21 by a sealing plate 25. The reaction cup placement hole 211 can be a perforation or a blind hole. In this embodiment, a blind hole is used as an example. The first temperature sensor 24 is provided near the bottom of the reaction cup placement hole 211. When the reaction cup 4 containing the reaction solution is placed in the reaction cup placement hole 211, the reaction solution can be close to the first temperature sensor 24, which facilitates the first temperature sensor 24 to accurately detect the temperature at the location of the reaction solution, thereby improving the accuracy and stability of the experimental data.

[0044] The circuit board 23 is arranged on the upper surface of the turntable heating element 22. The circuit board 23 and the turntable heating element 22 rotate together with the incubation tray 21. A first control module (not shown in the figure) is provided on the circuit board 23. The first control module is electrically connected to the first temperature sensor 24 and the turntable heating element 22 respectively. After receiving the temperature from the first temperature sensor 24, the first control module automatically adjusts the heating value of the turntable heating element 22, thereby ensuring that the temperature of the incubation tray 21 is basically maintained within a first preset threshold value. The first preset threshold value can be a single value or a range of values.

[0045] See also Figure 8 and Figure 9 The incubation seat assembly 1 further includes a bottom plate 13 and a support 14, and the incubation seat 11 is mounted on the bottom plate 13 through the support 14. The incubation seat 11 includes a bottom wall 111 and a side wall 112, the bottom wall 111 is circular, and the side wall 112 extends along the circumference of the bottom wall 111.

[0046] A first heating element 15 and a first heat-insulating element 16 are provided on the side walls 112 and / or the bottom wall 111 of the incubation seat 11. The first heat-insulating element 16 is provided on the outside or bottom side of the first heating element 15. In this embodiment, the first heating element 15 and the first heat-insulating element 16 are preferably provided on both the side walls 112 and the bottom wall 111 of the incubation seat 11, so that a heating and heat-insulating cavity is formed inside the incubation seat 11, and the bottom wall 111 and the side walls 112 of the heating and heat-insulating cavity both have heating and heat-insulating functions.

[0047] The first heating element 15 on the side wall 112 can be disposed on the inner or outer surface of the side wall 112. Accordingly, the first heat-insulating element 16 is disposed outside the first heating element 15 to prevent heat from dissipating outward. The first heating element 15 on the bottom wall 111 can be disposed on the upper or lower surface of the bottom wall 111. Accordingly, the first heat-insulating element 16 is disposed below the first heating element 15 to prevent heat from dissipating outward.

[0048] The incubation seat assembly 1 also includes a second temperature sensor 17. A second control module (not shown) is further provided on the circuit board 23. The second temperature sensor 17 is provided on the bottom wall 111 and / or the side wall 112 of the incubation seat 11. The second temperature sensor 17 is used to detect the ambient temperature inside the incubation seat 11. The second control module is electrically connected to the second temperature sensor 17 and the first heating element 15, respectively. After the second control module receives the temperature from the second temperature sensor 17, it automatically adjusts the calorific value of the first heating element 15, thereby ensuring that the temperature inside the incubation seat 11 is basically maintained within the second preset threshold. The second preset threshold is equal to the first preset threshold, or the second preset threshold may not be equal to the first preset threshold.

[0049] The upper cover 12 is provided with a second heating element 18 and a second heat-insulating element 19. The second heating element 18 can be provided on the top wall or the bottom wall of the upper cover 12, and the second heat-insulating element 19 is provided above the second heating element 18 to prevent heat from being dissipated outward.

[0050] The first heating element 15 and the second heating element 18 are both components that can convert electrical energy into heat energy and dissipate it outward, including heating films, heating wires, etc. In this embodiment, heating films are preferably used.

[0051] The first heat-insulating member 16 and the second heat-insulating member 19 are both made of heat-insulating materials, and in this embodiment, heat-insulating cotton is preferably used.

[0052] This embodiment mainly uses a turntable heating element 22 to directly heat the incubation tray 21 through contact heat transfer, and uses the first heating element 15 and the second heating element 18 on the incubation seat 11 to assist in heating the incubation tray 21. A first heat preservation element 16 is provided on the bottom wall 111 and the side wall 112 of the incubation seat 11, and a second heat preservation element 19 is provided on the upper cover 12. This can shorten the time for the incubation tray 21 to reach the target temperature, and at the same time provide a more stable ambient temperature for the inside of the incubation device. Even if the incubation device is in a situation where the external ambient temperature fluctuates greatly, the temperature stability of the incubation tray 21 can be maintained, thereby ensuring the consistency of incubation.

[0053] Combine Figure 1 and Figure 10The incubation drive assembly 3 includes a drive device 31, a transmission assembly 32 and a rotating shaft 33. The upper end of the rotating shaft 33 passes through the bottom wall 111 of the incubation seat 11 and extends into the interior of the incubation seat 11 and is connected to the incubation tray 21; the rotating shaft 33 is rotatably connected to the bottom wall 111 of the incubation seat 11; the lower end of the rotating shaft 33 is connected to the drive device 31 through the transmission assembly 32, and the transmission assembly 32 can be a belt transmission assembly or a chain transmission assembly. In this embodiment, the belt transmission assembly 32 is preferably provided. Specifically, the lower end of the rotating shaft 33 is provided with a driven pulley 321, the drive device 31 is preferably a motor, and a driving pulley 322 is provided on the drive shaft of the drive device 31, and a belt 323 is connected between the driving pulley 322 and the driven pulley 321.

[0054] The driving device 31 drives the rotating shaft 33 to rotate around its own axis through the transmission assembly 32, thereby driving the incubation tray 21 to rotate relative to the incubation seat 11.

[0055] The rotating shaft 33 is rotatably connected to the bottom wall 111 of the incubation seat 11. Specifically, an opening is provided on the bottom wall 111 of the incubation seat 11; a sleeve 34 and a bearing 35 are sleeved in the middle of the rotating shaft 33, the sleeve 34 being disposed in the opening, and the bearing 35 being disposed between the sleeve 34 and the rotating shaft 33, so that the rotating shaft 33 can rotate relative to the sleeve 34 and the incubation seat 11.

[0056] In other embodiments, a bearing may be directly disposed in the opening of the bottom wall 111 of the incubation seat 11 , and the rotating shaft 33 may be inserted into the bearing so that the rotating shaft 33 can rotate relative to the incubation seat 11 .

[0057] In this embodiment, a through hole 331 is provided in the middle of the rotating shaft 33. Through hole 331 extends through both ends of the rotating shaft 33. Preferably, through hole 331 extends axially through the rotating shaft 33. A slip ring 36 is provided at the lower end of through hole 331. The lead wires of slip ring 36 pass upward through through hole 331 and are electrically connected to the circuit board 23, preventing the lead wires from becoming entangled when the incubation tray 21 rotates. Slip ring 36 is an electrical component that connects the rotating body and transmits energy and signals. Its structure is conventional and will not be described in detail here.

[0058] To achieve the alternate rotation and stop of the incubation tray 21, a code disk 37 and a photoelectric detection device 38 are also provided below the rotating shaft 33. The code disk 37 is mounted on the rotating shaft 33 and is provided with rectangular holes spaced evenly around its circumference. The transmitting and receiving ends of the photoelectric detection device 38 are respectively located on the upper and lower sides of the code disk 37. The photoelectric detection device 38 and the drive device 31 are both connected to an external controller. The controller controls the drive device 31 to rotate and stop according to a preset rotation angle by receiving signals from the photoelectric detection device 38.

[0059] In summary, it can be seen that the utility model sets the turntable heating element 22 to contact the incubation tray 21 for heat transfer, so that the turntable heating element 22 can directly transfer heat to the incubation tray 21. Compared with the heat transfer through air in the prior art, it has the advantage of fast heat transfer, which is beneficial to shortening the preheating time; by setting the turntable heating element 22 close to the cup inlet and outlet window 121, it is beneficial to reduce the impact of external temperature fluctuations on the internal temperature of the incubation seat 11, and provide a relatively stable temperature environment for the inside of the incubation seat 11, thereby ensuring the consistency of incubation.
