Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of incubation bin assembly, in particular to an incubation bin liquid discharge device and an immunohistochemical device. BACKGROUND

[0002] The incubation bin is a bin body device capable of storing strains or carrying out biological culture, which is widely used in different fields such as medical health, medicine, biology, agriculture, scientific research units, etc., and has important technical effects such as test assay, pathological diagnosis, breeding development, etc. There are various types of incubation bins in the prior art, such as carbon dioxide incubation bin, constant temperature incubation bin, high humidity incubation bin, etc. Different types of incubation bins are suitable for different fields.

[0003] Among them, the incubation bin is usually a special equipment for immunohistochemical experiment, which is provided with a loading table, and a plurality of reaction stations are arranged on the loading table in a spaced manner, the reaction station is used for carrying an incubation sample or a slide of the sample, and then the sample or the slide is used for reaction, and the loading table is connected with a sealing cover plate, a liquid adding device, a liquid feeding pipeline and a liquid outlet pipeline and the like. During the reaction test of the sample or the slide, various doses of reagents need to be added, and during the incubation stage, the slide or the reaction sample added with the reagent needs to be heated to make the incubation proceed quickly. A large amount of waste liquid is generated during the incubation, and after the incubation is completed, the reaction station needs to be cooled immediately, and the waste liquid needs to be discharged in time. The lower part of the loading table of the incubation bin is connected with a waste liquid pipe through the liquid outlet pipeline, and is also provided with a venting port capable of venting. The waste liquid is gathered into the waste liquid pipe through the liquid outlet pipeline, the bottom of the waste liquid pipe is provided with a liquid outlet port, the waste liquid in the waste liquid pipe is discharged through the liquid outlet port, and the venting port can be ventilated to cool and cool.

[0004] However, the reagents used in each reaction station are different during actual reaction, so the waste liquid in the waste liquid pipe is easily mixed into a mixed state structure with different densities and layers, and is easily condensed into a relatively viscous paste structure after standing, which is relatively difficult to discharge from the liquid outlet port at the bottom of the waste liquid pipe. In order to solve this problem, the existing technology generally uses a vacuum pump for direct suction. The vacuum pumps on the market are usually divided into micro vacuum pumps and industrial vacuum pumps. Among them, the displacement of the micro vacuum pump is low, and it cannot be quickly sucked. The industrial vacuum pump is large in size and loud in noise, and is not suitable for the use environment of medical equipment such as incubation bin. There are also fans used as transfer components, which are large in displacement, small in size and low in noise. However, the fan has large displacement, and the suction force is not as good as that of the vacuum pump. If the fan is used for suction and liquid discharge throughout the process, the pipeline route is long, which is easy to cause pipeline blockage, cannot meet the purpose of discharging the waste liquid in the waste liquid pipe to quickly carry out the next test, needs to wait for a long time during suction, the efficiency is low, and it is not conducive to the timing of incubation and reaction operation and the timing of recording.

[0046] As shown in Figure 2 and Figure 3 , the liquid discharge channel 9 includes two front and rear interlocking housings 11, the rear housing 11 is fixed on the downwardly extending mounting plate 8, and the front housing 11 is detachably connected with the rear housing 11 through the fixing bolt 12, and the front and rear housings 11 are interlocked to form a sealed liquid discharge channel 9. Similarly, the driving air duct 10 also includes front and rear interlocking housings 11, and the front housing 11 of the driving air duct 10 is the shell of the negative pressure suction fan 13. It can be seen that the left liquid discharge channel 9 and the right driving air duct 10 are both connected in a split type structure, and the liquid discharge channel 9 and the driving air duct 10 are not connected and do not affect each other. In order to ensure the sealing of the negative pressure, the outer periphery of the housing 11 of the liquid discharge channel 9 and the driving air duct 10 is provided with an outwardly extending outer edge, and the outer edge is fastened and connected by the fixing bolt 12 after the front and rear housings 11 of each are butted.
