The fluid line includes a liquid conduit (preferably a flexible, corrosion resistant conduit), a fluid switch, and a mouthpiece. The fluid mid-end device 2200 includes a fluid switch, a central common chamber, and an interface. The mid-fluid end device 2200 may store and dispense liquids. The fluid end devices 2300A-2300D include a plurality of interfaces, waste recovery holes 2304, and a plurality of manifolds to enable application of liquid, waste recovery, and air blowing operations. The carrier tray receiving tray 2401 may drive the carrier tray to rotate and translate. The temperature maintaining device can maintain the temperature in the dyeing device to be approximately constant, so as to realize the optimal dyeing effect. The frame holds the various sections.
The main dyeing process is as follows: the mid-fluid end device 2200 distributes externally inflowing liquid to the fluid end devices 2300A-2300D. Liquid is delivered by fluid end devices 2300A-2300D to slides of carrier tray 401 held by carrier tray receptacle 2401. After the task of this liquid is completed, this liquid is in turn recovered by the fluid end devices 2300A-2300D. The positions of the fluid lines, the fluid mid-end device 2200, and the fluid end devices 2300A-2300D are typically maintained stationary relative to the ground, and the carrier tray receptacle 2401 rotates the carrier tray 401 to effect the staining of specimens on each slide one by one. The carrier tray receiving tray 2401 may receive the carrier tray 401 when open and be in an operative state when closed. The temperature maintaining means maintains the temperature in the dyeing apparatus substantially constant.
In fig. 6, 2200 represents a fluid mid-end device and 2300A-2300D fluid end devices. The dyeing module can have a plurality of fluid pipelines, and each fluid pipeline can only have one liquid. A fluid switch, which may be a solenoid valve, is inserted into the fluid line and controls the flow of liquid into the fluid center device. The dyeing module can be provided with a fluid middle-end device, a plurality of fluid inlets are distributed on the device for receiving liquid from outside, and a fluid switch is arranged on the inlet and can be an electromagnetic valve; the device has at least one fluid outlet, which may be provided without a switch. The fluid end device may be considered a liquid transfer station. The fluid medium end device has a liquid storage chamber therein. The staining module has at least one fluid end device therein. The fluid end device is connected with the fluid middle end device through a fluid pipeline. The fluid end device and the fluid middle end device realize liquid communication. When a switch in the fluid line in which a certain liquid is present is opened, the liquid flows into the fluid medium end device, so that the storage cavity of the fluid medium end device is filled with the liquid. To allow the liquid to flow into the end-of-fluid device, the air pressure within the reservoir of the end-of-fluid device may be reduced in some way. This method may be to use the pump 2800E to draw air from the chamber. When the liquid quantity in the storage cavity reaches a certain standard, a switch in a fluid pipeline where the liquid exists is closed, and the liquid is stopped from entering. In order to prevent the fluid middle end device from sucking excessive liquid, a liquid overflow outlet is arranged in the fluid middle end device. In operation of the fluid end-device, liquid in the storage chamber flows from the outlet of the fluid end-device, through the fluid end-device and onto the slide carried by the carrier tray 401. In order to make the liquid have a certain power, a pump is arranged on a pipeline between the fluid middle end device and the fluid end device to apply power to the liquid. During this process, the air pressure in the liquid storage chamber of the fluid center device is maintained equal to the atmospheric pressure by a certain method. When the amount of liquid on the slide reaches a desired level, the fluid end device changes operating conditions to flow the fluid end device and the liquid in the fluid line between the fluid end device and the fluid center device into the storage chamber of the fluid center device. The liquid in the storage chamber is discharged by a tube. After a certain time, the fluid end device removes liquid from the slide carried by the carrier tray 401 and delivers it to a waste recovery site (e.g., a waste reservoir). The task of the liquid is finished, the liquid which completes the task is discharged from the storage chamber by the fluid middle-end device, and the liquid is discharged out of the dyeing module through the corresponding fluid pipeline.
Fig. 7A is an isometric view of the mid-fluid end device and fig. 7B is a top view of the mid-fluid end device. 2201A-2201L are fluid switches, which may be solenoid valves. 2202 are central common chambers. The central common chamber has one or more inlets and one or more outlets through which a number of branch passages may be connected. The fluid switch is connected with each fluid pipeline and/or a negative pressure generating device (which can be a vacuum pump) and/or atmospheric pressure.
Figure 7C is an isometric view of a central common chamber. The central common chamber may be composed of a top, a waist and a bottom, each of which performs a different function. The central common chamber has a bottom and a waist, but may have one or more waists. The central common chamber has a top, a waist, and a bottom. The top has 5 openings, four of which are connected to the fluid switch and one of which is connected to the waist. The waist has 6 openings, four of which are connected to the fluid switch, and the other two of which are connected to the top, waist or bottom. The bottom may have 5-sided openings or 9-sided openings, of which 4-sided openings are the fluid outlets and one-sided openings are necessary to connect the waist. In this example, 2203 is the top of the central common chamber, 2204 is the waist of the central common chamber, and 2205 is the bottom of the central common chamber. 2206A are liquid outlets on the bottom 2205 of the central common chamber that connect to fluid lines leading to fluid end devices. The central common chamber top 2205 has two ports for connection to a negative pressure generating device, and one may be a liquid overflow and one may need to be connected to the atmosphere. The central common chamber waist 2204 is generally connected to a fluid line for liquids. When a certain liquid is needed, a fluid switch on a fluid pipeline of the liquid is turned on, and a switch connected with negative pressure is also turned on, so that the liquid enters the central public chamber. If the liquid enters too much, the liquid flows out from the liquid overflow outlet. When it is desired to deliver liquid from the central common chamber to the fluid end device, the switch to the atmospheric port is opened and the pump is started and liquid flows out of the central common chamber 2202.
Fig. 7D is a top view of the central common chamber. Fig. 7E is a B-B cross-sectional view of the central common chamber. 2207 is a conduit that is part of the top of the central common chamber. One end of the pipe is connected to the top and its length is such that its other end is just able to reach the bottom of the central common chamber. The tubing is connected through the top of the central common chamber to an external gas pressure controller, which may be a vacuum pump. The fluid medium end device changes the gas pressure in the liquid storage chamber through the pipeline. Meanwhile, the fluid middle-end device can also drain the liquid in the storage cavity for completing the task out of the storage cavity through the pipeline. When it is desired to drain the liquid in the central common chamber, a negative pressure is created in conduit 2207 and the switch to the atmosphere is opened and the liquid in the central common chamber can be drained from the fluid center device.
Fig. 7F is an isometric view of a fluid end device. Fig. 7G is a bottom view of the fluid end device. Fig. 7H is a front view of the fluid end device. Fig. 7I is a stepped cross-sectional view of G-G in a front view of the fluid end device. Fig. 7J is a cross-sectional view at the center of the fluid end device. 2301 is a fluid inlet head of a fluid end device, the fluid inlet head 2301 being connected to a fluid mid-end device by a fluid line. When a switch in the fluid line in which a certain liquid is present is opened, the liquid flows into the fluid medium end device, so that the storage cavity of the fluid medium end device is filled with the liquid. When the liquid quantity in the storage cavity reaches a certain standard, a switch in a fluid pipeline where the liquid exists is closed, and the liquid is stopped from entering. Subsequently, the fluid end device is activated and liquid in the storage chamber flows out of the outlet of the fluid middle end device through the fluid line to the fluid end device inlet head 2301 into the fluid end device. Reagent sequentially enters the common manifold 2308 and the lower tube via the inlet head 2301, accumulates a certain amount of liquid in the lower lumen for bubble prevention, and then flows out of the outlet 809 of the lower tube. 2302 is a waste outlet head of a fluid end device. The task-accomplishing liquid recovered from the slide eventually exits the fluid end device through the waste outlet head 2302 of the fluid end device. 2303 is a high pressure gas fitting of a fluid end device through which high pressure gas enters. The piping of the inlet header 2301 and the piping of the high pressure gas fitting 2303 merge into one common manifold 2308. Attached to the end of the common manifold is a drip needle 2305. In fig. 7G, 2304 is a waste liquid recovery hole. Waste liquid recovery holes 2304 are distributed in rows on both sides of a drip needle 2305. The number of the recovery holes of each waste liquid is between 5 and 15. The waste liquid recovery hole is connected with the negative pressure chamber. The negative pressure chamber is connected to a negative pressure source through a waste outlet head 2302, which can draw negative pressure through tubing to draw liquid out of the negative pressure chamber. When liquid is distributed, the waste liquid recovery hole 2304 and the high-pressure gas joint 2303 are in a non-working state, and the liquid passes through the liquid inlet head 2301 and the common manifold 2308 and finally goes out of the liquid dropping needle 2305 to the glass slide. When the liquid has completed the coloring task, the waste liquid recovery hole 2304 and the high-pressure gas joint 2303 start to operate. The high pressure gas enters the common manifold 2308 from the high pressure gas fitting 2303 and then travels in both directions. Upward flow, draining liquid in the conduit from the liquid inlet head 2301 out of the fluid end device to the fluid middle end device. Flows downward, out of the common manifold 2308 to the drip needles 2305 and blows liquid onto the slides. The high air pressure forces the liquid on the slide to spread from the center to both sides of the waste liquid recovery hole. Meanwhile, the low air pressure in the waste liquid recovery hole sucks the liquid into the negative pressure chamber, thereby completing the waste liquid removal work.
When the fluid end device dispenses reagent liquid onto the surface of the slide 402, the two-dimensional code 403 provided on the slide 402 can be identified by the identification device, labeled and the information is transmitted to the human-machine interaction system.

After the completion of a staining procedure, carrier tray receptacle 2401 rotates carrier tray 401 through an angle such that the next slide adjacent to the slide that completed the staining procedure is properly aligned with fluid end devices 2300A-2300D. The carrier tray 401 is coupled to the carrier tray receiving tray in a manner that maintains a relative position unchanged. 2401 of fig. 8B shows a carrier tray receiving tray. The carrier tray receptacle 2401 also has raised spatial geometries thereon, and these raised spatial geometries may be exactly combined with the pattern-drawing features on the bottom surface of the carrier tray. In one embodiment, a circular aperture 404 is provided in the carrier tray 401 that is coupled to a raised structure on the carrier tray receptacle 2401. The power device has a carrier rotation drive mechanism 2400 that drives the carrier tray carrier 2401 to rotate. The receiving receptacle rotational drive mechanism 2400 may be an electric motor. The carrier tray rotational drive mechanism 2400 and the carrier tray carrier 2401 may be connected to each other by a timing belt. The carrier tray lifting mechanism 2500 and the carrier tray carrying tray 2401 can be connected by a screw rod to realize the lifting linear motion of the carrier tray carrying tray 2401.
In fig. 8C 2400 shows a carrier tray receiving tray, 2500 shows a receiving tray lifting mechanism, and 2600 shows a frame of a dyeing apparatus. The carrier tray supports at least a lifting linear movement relative to the frame of the dyeing device and a circular movement relative to the frame of the dyeing device. The carrier tray receiving tray has two states of open and working. In the open state, the carrier tray receiving tray does not perform a circular motion. The carrier tray receiving tray only moves linearly during opening and during returning. In the working state, the carrier tray carrying tray only performs circular motion. In fig. 6, the carrier tray receiving tray is in an operative state. In the operational state, the carrier tray receiving tray can enable at least one slide on the carrier tray to face the fluid end device after each circular movement is stopped. Meanwhile, a device for detecting whether the position of the carrier tray for carrying the carrier is accurate or not is also arranged on the rack of the dyeing device. The power device provides power for the carrier tray bearing support. In fig. 8C, the carrier tray receiving tray is in an open state.
The foregoing is a further detailed description of the invention in connection with specific/preferred embodiments, and it is not intended that the invention be limited to such description. It will be apparent to those skilled in the art that several alternatives or modifications can be made to the described embodiments without departing from the spirit of the invention, and these alternatives or modifications should be considered to be within the scope of the invention.
