Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.

[0044] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0045] As shown in Figures 1 to 3 According to the first aspect of the present application, the present application provides a blood culture instrument, which comprises a cabinet 10, an incubation assembly 20 and a heat dissipation assembly 30, and the incubation assembly 20 and the heat dissipation assembly 30 are both arranged in the cabinet 10. The incubation assembly 20 is used for placing a sample container to incubate a sample in the sample container, and the heat dissipation assembly 30 is used at least for exchanging the gas in the cabinet 10 with the gas outside the cabinet 10, so that the incubation temperature in the cabinet 10 can be maintained within a suitable range to provide suitable incubation conditions for the growth of microorganisms, solve the problem that the blood culture instrument is prone to high-temperature out-of-control during use, and avoid the blood culture instrument being not conducive to the growth of microorganisms due to high-temperature out-of-control, so that medical experiments cannot be carried out, and even cause certain losses.

[0046] In an optional embodiment, the cabinet 10 is formed with a heat dissipation area and an incubation area, the incubation assembly 20 is arranged in the incubation area, and the heat dissipation assembly 30 is arranged in the heat dissipation area, so that the heat dissipation assembly 30 can be used to discharge the gas in the cabinet 10 from the heat dissipation area to the outside of the cabinet 10 and introduce the gas outside the cabinet 10 into the heat dissipation area, so as to exchange the gas in the cabinet 10 with the gas outside the cabinet 10, solve the problem that the heat in the cabinet 10 cannot be dissipated in time, and maintain the gas in the cabinet 10 at a suitable temperature.

[0047] After the above technical scheme, since the cabinet 10 is provided with the component 40, the component 40 and the incubation assembly 20 generate a large amount of heat during operation. When the high-temperature gas in the cabinet 10 cannot be discharged, the high-temperature gas easily transfers heat to the incubation assembly 20 by heat radiation, heat convection and / or heat conduction, so that the temperature of the incubation assembly 20 is increased, resulting in high-temperature runaway, which is not conducive to the growth of microorganisms. Therefore, the application can discharge the high-temperature gas in the cabinet 10 from the heat dissipation area to the outside of the cabinet and introduce the gas outside the cabinet 10 into the heat dissipation area by arranging the heat dissipation assembly 30 in the heat dissipation area, so that the temperature in the cabinet 10 can always be kept in dynamic balance, effectively prevent the high-temperature gas in the cabinet 10 from transferring heat to the incubation assembly 20, avoid high-temperature runaway of the incubation assembly 20, which is not conducive to the growth of microorganisms, and solve the problem of insufficient heat dissipation capacity of the blood culture instrument.

[0048] It should be noted that the heat dissipation area and the incubation area can be two independent areas in the cabinet 10, or different positions of one area, which is not limited by the application. The main area is formed by the installation position of the incubation assembly 20 and the heat dissipation assembly 30, that is, the area in the cabinet 10 for installing the incubation assembly 20 is the incubation area, and the area in the cabinet 10 for installing the heat dissipation assembly 30 is the heat dissipation area.

[0049] In an optional embodiment, the cabinet 10 includes a cabinet door 12, a back plate 11a, a side plate 11b, a bottom plate 11c and a top plate 11d, which cooperate to form a cabinet body 11 with a heat dissipation area and an incubation area. The incubation assembly 20 is arranged in the cabinet body 11 and located in the incubation area, and the heat dissipation assembly 30 and the component 40 are arranged in the cabinet body 11 and located in the heat dissipation area. The cabinet body 11 has an open state or a closed state, and the cabinet door 12 is used to open or close the cabinet. When the cabinet body 11 is in the open state, the operator or the operating robot can perform the operation of putting the sample container into the incubation assembly 20 and the operation of taking out the sample container. When the cabinet body 11 is in the closed state, the incubation assembly 20 can provide an incubation environment for the growth of microorganisms, and the temperature is generally maintained in the range of 30-40℃. The component 40 includes but is not limited to a power supply and a central control assembly such as a board card arranged in the cabinet 10.

[0050] In an optional embodiment, the incubation assembly 20 comprises a heating element and at least one incubation block 21 for accommodating the sample container, the incubation block 21 is arranged in the incubation area, and the heating element is used to heat the incubation block to heat the sample in the sample container, so as to ensure better growth of the microorganism in the sample container.

[0051] In an optional embodiment, the heating element is in contact with the incubation block 21, which facilitates the rapid transmission of heat generated by the heating element to the sample container through the incubation block 21, and better temperature control can be achieved, so that the sample in the sample container is maintained within a preset temperature range.

[0052] In a specific application, when the box door 12 is in an open state, the operator or the operating robot can perform the operation of placing the sample container in the incubation block 21 and the operation of taking out the sample container. When the box door 12 is in a closed state, the incubation block 21 can provide an incubation environment for the growth of the microorganism. The cabinet 10 is provided with a heat preservation layer, which is used to maintain the temperature in the cabinet 10 and reduce the energy consumption of the blood culture instrument, and prevent the sample from being pretreated unsuccessfully due to the sudden change of the temperature in the cabinet 10 when power failure occurs.

[0053] In an optional embodiment, the detection assembly is arranged in the incubation area to detect the growth of the microorganism in the sample container.

[0054] In an optional embodiment, the heat dissipation assembly 30 comprises a heat dissipation fan 31, an air inlet 32 and an air outlet 33, the heat dissipation fan 31 is used to at least discharge the gas in the heat dissipation area from the air outlet 33 to the outside of the cabinet and introduce the gas outside the cabinet into the heat dissipation area from the air inlet 32, so that the gas in the cabinet 10 can be exchanged with the gas outside the cabinet. The temperature of the gas in the heat dissipation area is higher than that of the gas outside the cabinet, so that the high-temperature gas in the heat dissipation area can be effectively discharged from the air outlet 33, and the low-temperature gas outside the cabinet can be introduced into the heat dissipation area through the air inlet 32, so that the temperature of the gas in the heat dissipation area can always remain in dynamic balance, effectively preventing the high-temperature gas in the heat dissipation area from transferring heat to the incubation assembly 20, avoiding the temperature of the incubation assembly 20 being too high, and solving the problem of insufficient heat dissipation capacity of the blood culture instrument.

[0055] It should be noted that the application introduces the gas outside the cabinet 10 from the air inlet 32 into the heat dissipation area through the heat dissipation fan 31, and discharges the gas in the heat dissipation area from the air outlet 33 outside the cabinet 10. Through the continuous circulation of gas introduction and discharge, the temperature of the gas in the heat dissipation area can always maintain dynamic balance. Among them, the heat dissipation fan 31 mainly provides power for the introduction and discharge of the gas, so that the exchange of the gas in the cabinet 10 and the gas outside the cabinet can be faster, and the high-temperature gas can be discharged better; when the temperature of the gas in the cabinet 10 and the temperature of the gas outside the cabinet 10 are not much different, the heat dissipation fan 31 can be selected to be closed, so that the gas in the cabinet 10 can be discharged from the air outlet 33, and the gas outside the cabinet 10 can enter from the air inlet 32. Of course, the heat dissipation fan 31 can also be selected to be turned on, which is not limited by the application.

[0056] In an optional embodiment, the heat dissipation fan 31 is arranged at a position closer to the air outlet 33 among the air outlet 33 and the air inlet 32, so as to discharge the gas in the heat dissipation area from the air outlet 33 outside the cabinet 10, so that the high-temperature gas in the cabinet 10 can be quickly guided to the outside of the cabinet 10, effectively reducing the influence of the high-temperature gas discharged by the heat dissipation fan 31 on the incubation assembly 20 in the incubation area; at the same time, after the high-temperature gas in the cabinet 10 is discharged, a negative pressure is generated in the cabinet 10, so that the gas outside the cabinet can be introduced into the cabinet 10 through the air inlet 32, so as to realize the exchange of the gas in the cabinet 10 and the gas outside the cabinet, so as to reduce the temperature of the gas in the cabinet 10, thereby effectively reducing the temperature rise of the components 40 and the detection assembly in the working process, maintaining the temperature of the gas in the cabinet 10 within a certain temperature range, avoiding the influence of the temperature of the incubation assembly 20, and solving the problem of insufficient heat dissipation capacity of the blood culture instrument.

[0057] In an optional embodiment, the heat dissipation fan 31 is arranged at the air outlet 33, so as to discharge the gas in the heat dissipation area from the air outlet 33 outside the cabinet 10, so that the high-temperature gas in the cabinet 10 can be quickly guided to the outside of the cabinet 10, effectively reducing the influence of the high-temperature gas discharged by the heat dissipation fan 31 on the incubation assembly 20 in the incubation area.

[0058] In an optional embodiment, the gas flow path formed between the air inlet 32 and the heat dissipation fan 31 and the air outlet 33 passes through the heating area of the heat dissipation area, so that the gas in the cabinet 10 can directly contact the components 40 in the heating area, thereby greatly enhancing the heat dissipation effect of the blood culture instrument and effectively improving the working temperature of the components 40, avoiding the influence of the temperature of the incubation assembly 20.

[0059] In an alternative embodiment, the air inlet 32 is arranged on or near the bottom plate 11c, and the air outlet 33 is arranged on or near the top plate 11d, so that the hot air in the cabinet 10 can be quickly discharged from the air outlet 33 based on the principle of hot air rising, and the cold air outside the cabinet 10 can enter the cabinet 10 from the air inlet 32 to form a gas flow path, so that the gas in the heat dissipation area with a higher temperature can be exchanged with the gas outside the cabinet 10 with a lower temperature; at the same time, the air inlet temperature of the heat dissipation area can also be effectively guaranteed, and the high-temperature gas in the heat dissipation area can be prevented from entering the cabinet 10 again from the air inlet 32.

[0060] In an alternative embodiment, the air outlet 33 is arranged on the back plate 11a near the top plate 11d, so that when the heat dissipation fan 31 is working, the high-temperature gas in the heat dissipation area can be discharged to the back of the blood culture instrument through the air outlet 33, and the gas discharged from the air outlet 33 can rise along the height direction of the back plate 11a, without affecting the operator or the appearance of the product.

[0061] In an alternative embodiment, the air inlet 32 is arranged on the bottom plate 11c or the back plate 11a near the bottom plate 11c, so that the gas outside the cabinet 10 can enter the heat dissipation area from the air inlet 32 at a lower position, and the high-temperature gas in the heat dissipation area can be discharged to the outside through the air outlet 33 near the top plate 11d, thereby effectively guaranteeing the air inlet temperature of the heat dissipation area and preventing the high-temperature gas in the heat dissipation area from entering the cabinet 10 again from the air inlet 32. In an alternative embodiment, as shown in Figures 1 to 3 the cabinet 11 is provided with a first partition plate 11e, and the first partition plate 11e is used to divide the cabinet 11 into an incubation area and a heat dissipation area, and the incubation assembly 20 is arranged in the incubation area, which is simple in structure and convenient to use.

[0062] In an alternative embodiment, the first partition plate 11e is formed on the incubation assembly 20 to divide the cabinet 11 into an incubation area and a heat dissipation area.

[0063] In an alternative embodiment, as shown in Figures 4 to 7 the cabinet 10 is provided with at least one drawer 13 for carrying the incubation assembly 20, and the drawer 13 is movably installed in the cabinet 11 of the cabinet 10 to drive the incubation assembly 20 to move between an open position and a closed position; in the open position, the incubation assembly 20 is at least partially exposed outside the cabinet 11, and in the closed position, the incubation assembly 20 is accommodated in the cabinet 11 to incubate the sample in the sample container, and when the incubation assembly 20 is in the closed position, the drawer 13 divides the cabinet 11 into the above-mentioned incubation area and the above-mentioned heat dissipation area.

[0064] Exemplarily, the plurality of drawers 13 are movably installed in the cabinet 11. Each drawer 13 includes a drawer main body 131 and a drawer panel 132, the drawer main body 131 is a main supporting structure of the incubation assembly 20, and the drawer panel 132 is fixedly connected to the drawer main body 131 to drive the incubation assembly 20 to move between the open position and the closed position under the action of an external force.

[0065] Exemplarily, the incubation assembly 20 is driven to be positioned at the closed position when the panel is closed, and is driven to be positioned at the open position when the panel is opened, facilitating the placement and removal of the sample container.

[0066] It should be noted that the incubation assembly 20 is arranged in the drawer main body 131 to form an incubation area, and the drawer main body 131 is movably installed in the cabinet 11, that is, the incubation area is at least partially located outside the cabinet 11 in the open position and is located outside the cabinet 11 in the closed position, and the heat dissipation area can be other areas in the cabinet 10 except the drawer main body 131, which is not limited in the present application.

[0067] In an optional embodiment, the cabinet 11 is provided with a second partition plate 11f, the second partition plate 11f is used to divide the cabinet 10 into a plurality of chambers 112 that are in communication with each other, and the drawer main body 131 is movably installed in each chamber 112, so that the sample container can be placed and removed when the drawer main body 131 is in the open position.

[0068] In an optional embodiment, the second partition plate 11f has a vent hole 111, and adjacent two chambers 112 are in communication with each other through the vent hole 111, so that the gas in each chamber 112 can be exchanged through the vent hole 111 and then discharged through the air outlet 33, and the gas outside the cabinet 10 is introduced through the air inlet 32 to form a gas flow path, so as to exchange the gas in each chamber 112 with the gas outside the cabinet 10.

[0069] It should be noted that the cabinet 11 can also have only one chamber 112, and the plurality of drawer main bodies 131 can be installed in a single chamber 112 through a slide rail assembly, which is not limited in the present application.

[0070] In an optional embodiment, the vent hole 111 includes a first vent hole 1111 and a second vent hole 1112, the first vent hole 1111 is arranged in a direction perpendicular to the movement direction of the drawer main body 131, and the second vent hole 1112 is arranged in a direction parallel to the movement direction of the drawer main body 131, to ensure that the gas in each chamber 112 can be quickly exchanged.

[0071] In an optional embodiment, the air inlet 32 and the number of air outlets 33 are one or more, one or more air inlets 32 are arranged at the bottom or near the bottom of the cabinet 10, and one or more air outlets 33 are arranged at the top or near the top of the cabinet 10, which effectively ensures the air inlet temperature of the heat dissipation area and avoids the high-temperature gas in the heat dissipation area from entering the cabinet 10 again through the air inlet 32.

[0072] In an optional embodiment, the components 40 include a display assembly and an information acquisition assembly, and the display assembly and the information acquisition assembly are arranged on the cabinet. The display assembly is used for display and / or interactive operation, and the information acquisition assembly is used for acquiring information of samples and sample containers.

[0073] For example, the cabinet 10 has a first area and a second area, a plurality of drawers 13 are arranged in the first area along the height direction of the cabinet 10, and the display assembly and the information acquisition assembly are arranged in the second area. When the heat dissipation realizes the exchange of air inside and outside the cabinet 10, the display assembly and the information acquisition assembly can also be cooled, avoiding the influence of heat generated by the display assembly and the information acquisition assembly on the incubation assembly 20 during operation.

[0074] In an optional embodiment, the blood culture instrument includes a temperature sensor arranged in the cabinet 10, which is used to detect the temperature of the incubation area and / or the incubation assembly 20, so as to realize real-time monitoring of the temperature of the incubation area and / or the incubation assembly 20, prevent the high-temperature gas in the heat dissipation area from affecting the temperature of the incubation area, and make the heat dissipation assembly 30 start working after the temperature in the incubation area reaches the preset temperature, so as to minimize the influence of temperature change in the incubation area, which is conducive to the growth of microorganisms.

[0075] In an optional embodiment, the blood culture instrument includes a controller, which is communicatively connected with the temperature sensor, the incubation assembly 20 and the heat dissipation fan 31, so that the controller can control the driving signal of the heat dissipation fan 31 according to the temperature detected by the temperature sensor, so as to maintain the temperature in the cabinet 10 within the preset temperature range.

[0076] For example, the controller outputs different pulse width modulation signals according to the temperature detected by the temperature sensor, and converts the pulse width modulation signals into driving signals for controlling the working of the heat dissipation fan 31, which is used to drive the heat dissipation fan 31 to rotate, so as to maintain the temperature in the cabinet 10 within the preset temperature range.

[0077] Specifically, when the temperature sensor transmits the collected gas temperature to the controller, the controller controls the heat dissipation fan 31 to discharge the gas in the heat dissipation area. Wherein, when the temperature collected by the temperature sensor is higher than the temperature threshold, the controller outputs a drive signal with an increased duty cycle to the heat dissipation fan 31, so that the rotation speed of the heat dissipation fan 31 can be adjusted according to the temperature of the incubation area, which is conducive to ensuring the exchange of gas in the cabinet 10 and the gas outside the cabinet, and also can reduce energy consumption.

[0078] Wherein, when the temperature T0 in the incubation area is lower than the first temperature threshold T1, the duty cycle of the drive signal is 0, at this time the heat dissipation fan 31 does not work; when the temperature T0 in the incubation area is higher than the second temperature threshold T2, the duty cycle of the drive signal is 1, at this time the heat dissipation fan 31 works at full power; when the temperature T0 in the incubation area is between the first temperature threshold T1 and the second temperature threshold T2, the duty cycle of the drive signal is (T0-T1) / (T2-T1), so that the heat dissipation fan 31 can work according to different duty cycles, so that the temperature in the cabinet 10 can be maintained within the preset temperature range.

[0079] As shown in Figures 1 to 7 According to the second aspect of the present application, the present application provides a blood culture instrument, which comprises a cabinet 10, an incubation assembly 20, a heat dissipation assembly 30, a temperature sensor and a controller. The incubation assembly 20 is arranged in the cabinet 10 and is used for placing a sample container to incubate a sample in the sample container. The heat dissipation assembly 30 comprises a heat dissipation fan 31, an air inlet 32 and an air outlet 33. The heat dissipation fan 31 is used for discharging the gas in the cabinet 10 out of the cabinet 10 through the air outlet 33, and introducing the gas outside the cabinet into the cabinet 10 from the air inlet 32, so that the gas in the cabinet 10 can exchange with the gas outside the cabinet, wherein the temperature of the gas in the cabinet 10 is higher than the temperature of the gas outside the cabinet.
