Description

Gas pressure supply system and method, biochemical substance analysis device TECHNICAL FIELD

[0001] The present application relates to pressure control, in particular to a gas pressure supply system, a gas pressure supply method and a biochemical substance analysis device. BACKGROUND

[0002] In the related art, a negative pressure generated by a vacuum pump of a gas circuit system is required to perform a desired operation on a target object, for example, in the field of biochemistry or medicine, a target slide can be placed on a support platform and the vacuum pump is connected to the support platform, so that the target slide is adsorbed on the support platform.

[0003] However, such a gas circuit system can only output a negative pressure to the target object, and the function is single. If a positive pressure is also required, such as a positive pressure to drive a fluid into the target object for biochemical reaction, a pressure pump capable of outputting a positive pressure also needs to be additionally configured in the liquid circuit system, which undoubtedly reduces the utilization rate of the entire system.

The first power source is configured to generate a first pressure. The second power source is configured to generate a second pressure, one of the first pressure and the second pressure is higher than the atmospheric pressure, and the other is lower than the atmospheric pressure. The first primary transmission assembly is connected to the first power source. The second primary transmission assembly is connected to the second power source. The first secondary transmission assembly is connected to the first primary transmission assembly and the second primary transmission assembly, and selectively communicates at least one of the first primary transmission assembly and the second primary transmission assembly.

The second output end is connected to the second secondary transmission assembly. The second output end is configured to output the second pressure transmitted from the second power source, the second primary transmission assembly and the second secondary transmission assembly.

[0007] The second aspect of the present application provides a gas pressure supply method, comprising: starting a first power source, the first power source outputting a first pressure to a first output end through a first primary transmission assembly and a first secondary transmission assembly; starting a second power source, the second power source outputting a second pressure through a second primary transmission assembly and a second secondary transmission assembly, one of the first pressure and the second pressure being higher than the atmospheric pressure, and the other being lower than the atmospheric pressure; the first secondary transmission assembly being connected to the second primary transmission assembly; and the second power source outputting the second pressure to the first output end through the second primary transmission assembly and the first secondary transmission assembly.

[0008] The third aspect of the present application provides a biochemical substance analysis device, comprising the above gas pressure supply system, a first liquid path system and a second liquid path system. The first liquid path system is configured to supply a first fluid to a first target slide. The first liquid path system is connected to the first output end of the gas pressure supply system. The second liquid path system is configured to supply a second fluid to a second target slide, the first fluid being the same as or different from the second fluid.

[0022] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments.

[0023] It should be noted that when a component is referred to as being "on" or "connected to" another component, it can be directly on or connected to the other component, or intervening components can also be present. When a component is referred to as being "disposed on" another component, it can be directly disposed on the other component, or intervening components can also be present. The term "and / or" as used herein includes all possible combinations of one or more of the associated listed items.

[0024] It should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described can be performed in an order different from that in the flowchart. The methods disclosed in the embodiments of the present application include one or more steps or actions for implementing the methods. The method steps and / or actions can be interchanged with each other without departing from the scope of the claims. Unless a specific order of steps or actions is specified, the order and / or use of specific steps and / or actions can be modified without departing from the scope of the claims.

[0025] Referring to FIG. 1, an embodiment of the present application provides a gas pressure supply system 100 for outputting a first pressure P1 and a second pressure P2. One of the first pressure P1 and the second pressure P2 is higher than the atmospheric pressure, and the other is lower than the atmospheric pressure. In some embodiments, the first pressure P1 is positive pressure, and the second pressure P2 is negative pressure. In other embodiments, the first pressure P1 can also be negative pressure, and the second pressure P2 can also be positive pressure. The gas pressure supply system 100 includes a first power source 10, a second power source 12, a first primary transmission assembly 20, a second primary transmission assembly 22, a first secondary transmission assembly 30, a second secondary transmission assembly 32, a first output end 40, and a second output end 42.

[0026] The first power source 10 can generate a first pressure P1. The second power source 12 can generate a second pressure P2. For example, the first pressure P1 is positive pressure, the first power source 10 can drive the gas to move in a positive direction, which means the direction of driving the gas to flow from the first power source 10 to the first primary transfer assembly 20; the second pressure P2 is negative pressure, the second power source 12 can drive the gas to move in a reverse direction, which means the direction of extracting the gas to flow from the second primary transfer assembly 22 to the second power source 12. The first power source 10 and the second power source 12 can work independently. In some embodiments, the first power source 10 and the second power source 12 can work in sequence or in parallel. "Parallel work" means that the working time of the first power source 10 and the second power source 12 completely overlaps or at least partially overlaps on the time axis. The first power source 10 and the second power source 12 can be various types of pumps that can drive the gas to move, such as plunger pump, diaphragm pump, gear pump, peristaltic pump, vane pump or screw pump, etc.

[0027] The first primary transfer assembly 20 is connected to the first power source 10. The second primary transfer assembly 22 is connected to the second power source 12. Wherein, the "connection" in the present application means that the modules are connected to each other through pipes or other suitable components. The first primary transfer assembly 20 and the second primary transfer assembly 22 can be various types of electromagnetic valves, selector valves (such as rotary valves) or combinations thereof. The first primary transfer assembly 20 and the second primary transfer assembly 22 can also be a combination of the above-mentioned valves and multi-way joints.

[0028] The first secondary transmission component 30 is connected to the first primary transmission component 20 and the second primary transmission component 22, and selectively communicates at least one of the first primary transmission component 20 and the second primary transmission component 22. The second secondary transmission component 32 is connected to the second primary transmission component 22. Thus, the second primary transmission component 22 has a shunt effect. When the first secondary transmission component 30 communicates the first primary transmission component 20, the first primary transmission component 20 can transmit the first pressure PI generated by the first power source 10 to the first secondary transmission component 30; when the first secondary transmission component 30 communicates the second primary transmission component 22, the second primary transmission component 22 can transmit the second pressure P2 generated by the second power source 12 to the first secondary transmission component 30; when the first secondary transmission component 30 communicates both the first primary transmission component 20 and the second primary transmission component 22, the first primary transmission component 20 can transmit the first pressure PI generated by the first power source 10 to the first secondary transmission component 30, and the second primary transmission component 22 can transmit the second pressure P2 generated by the first power source 10 to the first secondary transmission component 30, and the first secondary transmission component 30 outputs the first pressure PI and the second pressure P2 after combining them. In some embodiments, the second secondary transmission component 32 is also connected to the first primary transmission component 20, and selectively communicates at least one of the second primary transmission component 22 and the first primary transmission component 20. At this time, the first primary transmission component 20 also has a shunt effect. When the second secondary transmission component 32 communicates the second primary transmission component 22, the second primary transmission component 22 can transmit the second pressure P2 generated by the second power source 12 to the second secondary transmission component 32; when the second secondary transmission component 32 communicates the first primary transmission component 20, the first primary transmission component 20 can transmit the first pressure PI generated by the first power source 10 to the second secondary transmission component 32; when the second secondary transmission component 32 communicates both the first primary transmission component 20 and the second primary transmission component 22, the second primary transmission component 22 can transmit the second pressure P2 generated by the second power source 12 to the second secondary transmission component 32, and the first primary transmission component 20 can transmit the first pressure PI generated by the first power source 10 to the second secondary transmission component 32, and the second secondary transmission component 32 outputs the first pressure PI and the second pressure P2 after combining them. The first secondary transmission component 30 and the second secondary transmission component 32 can be various types of electromagnetic valves, selector valves (such as rotary valves), or combinations thereof. The first secondary transmission component 30 and the second secondary transmission component 32 can also be combinations of the above valves and multi-way junctions.

[0029] The first output end 40 is connected to the first secondary transmission component 30. The first output end 40 can output the first pressure P1 transmitted from the first power source 10, the first primary transmission component 20 and the first secondary transmission component 30. Due to the shunting effect of the second primary transmission component 22, the first output end 40 can also output the second pressure P2 transmitted from the second power source 12, the second primary transmission component 22 and the first secondary transmission component 30. The second output end 42 is connected to the second secondary transmission component 32. The second output end 42 can output the second pressure P2 transmitted from the second power source 12, the second primary transmission component 22 and the second secondary transmission component 32. In some embodiments, when the second secondary transmission component 32 is also connected to the first primary transmission component 20, due to the shunting effect of the first primary transmission component 20, the second output end 42 can also output the first pressure P1 transmitted from the first power source 10, the first primary transmission component 20 and the second secondary transmission component 32.

[0030] In the above embodiments, when the pneumatic supply system 100 includes the first power source 10 and the second power source 12, the number of output ends is taken as two for example. Referring to FIG. 2, in other embodiments, when the pneumatic supply system 100 includes the first power source 10 and the second power source 12, the number of output ends can also be increased. For example, the number of the first secondary transmission components 30 and the first output ends 40 can be both two and connected one by one, and each first secondary transmission component 30 is connected to the first primary transmission component 20 and the second primary transmission component 22. At this time, when the pneumatic supply system 100 includes the first power source 10 and the second power source 12, pressure output can be performed through three output ends without increasing the total number of power sources, and each output end can act on a target object, thereby further improving the utilization rate of the pneumatic supply system 100. In some embodiments, the number of the second secondary transmission components 32 and the second output ends 42 can also be both two and connected one by one, and each second secondary transmission component 32 is connected to the first primary transmission component 20 and the second primary transmission component 22. At this time, when the pneumatic supply system 100 includes the first power source 10 and the second power source 12, pressure output can be performed through four output ends without increasing the total number of power sources, and each output end can act on a target object, thereby further improving the utilization rate of the pneumatic supply system 100. In other embodiments, the number of output ends can also be changed as needed.

[0031] In the related art, two pressure pumps are needed to output positive pressure and negative pressure respectively, one of which can only output positive pressure and the other can only output negative pressure, so the air pressure supply system is single in function. Moreover, two pressure pumps are set to perform different operations on the same target object, such as adsorption and fluid loading of the target object respectively, which reduces the utilization rate of the air pressure supply system. The first power source 10 and the second power source 12 are set to output pressure through at least two output ends. Due to the shunt effect of the second primary transmission assembly 22, the second power source 12 can output the second pressure P2 to the first output end 40 and the second output end 42 respectively, so that the first output end 40 is not limited to output the first pressure P1, that is, the first output end 40 can independently output the first pressure P1 and the second pressure P2. For example, by setting two power sources, if a target object is arranged downstream of the first output end 40 (not shown in the figure), not only the negative pressure output by the first output end 40 can be used to adsorb and fix the target object, but also the positive pressure output by the first output end 40 can be used to realize fluid loading. That is, the first output end 40 can independently output the first pressure P1 and the second pressure P2 to realize the adsorption and fluid loading of the target object; the second output end 42 can also output the second pressure P2 to realize the adsorption and fluid loading of another target object. Therefore, the utilization rate of the air pressure supply system 100 can be improved.

[0032] Similarly, when the second secondary transmission assembly 32 is also connected to the first primary transmission assembly 20, due to the shunt effect of the first primary transmission assembly 20, the first power source 10 can output the first pressure P1 to the first output end 40 and the second output end 42 respectively, so that the second output end 42 is not limited to output the second pressure P2, that is, the second output end 42 can independently output the first pressure P1 and the second pressure P2. At this time, the first output end 40 can independently output the first pressure P1 and the second pressure P2, and the second output end 42 can also independently output the first pressure P1 and the second pressure P2, thereby further improving the utilization rate of the air pressure supply system 100.

[0033] More specifically, as shown in FIG. 1 and FIG. 2, in some embodiments, the outputs of the first output end 40 and the second output end 42 can include the following cases: first, when the first secondary transmission component 30 is connected to the first primary transmission component 20 and the second secondary transmission component 32 is connected to the second primary transmission component 22, the first output end 40 outputs the first pressure P1 and the second output end 42 outputs the second pressure P2; second, when the first secondary transmission component 30 and the second secondary transmission component 32 are both connected to the second primary transmission component 22, the first output end 40 outputs the second pressure P2 and the second output end 42 outputs the second pressure P2; third, when the first secondary transmission component 30 and the second secondary transmission component 32 are both connected to the first primary transmission component 20, the first output end 40 outputs the first pressure P1 and the second output end 42 outputs the first pressure P1; fourth, when the first secondary transmission component 30 is connected to the second primary transmission component 22 and the second secondary transmission component 32 is connected to the first primary transmission component 20, the first output end 40 outputs the second pressure P2 and the second output end 42 outputs the first pressure P1.

[0034] Referring to FIG. 3, in some embodiments, the pneumatic supply system 100 can further include a first gas storage 50 connected between the first power source 10 and the first primary transmission component 20, and the first power source 10 can generate the first pressure P1 in the first gas storage 50. Compared with directly connecting the first power source 10 and the first primary transmission component 20 through a pipeline (the inner volume of the pipeline is generally only in the order of milliliters, and when the first power source 10 is turned off, the first pressure P1 output by the first primary transmission component 20 drops quickly, in order to avoid the drop of the first pressure P1, the first power source 10 needs to work all the time), by introducing the first gas storage 50 with a larger volume, even if the first power source 10 is turned off, the first pressure P1 output by the first primary transmission component 20 changes slowly, so that the first primary transmission component 20 can continuously and stably output the first pressure P1, and the first power source 10 does not need to work all the time, which is also conducive to improving the service life of the first power source 10.

[0035] Further, the pneumatic supply system 100 can further include a second gas storage 52 connected between the second power source 12 and the second primary transmission component 22, and the second power source 12 can generate the second pressure P2 in the second gas storage 52. Compared with directly connecting the second power source 12 and the second primary transmission component 22 through a pipeline, by introducing the second gas storage 52 with a larger volume, even if the second power source 12 is turned off, the second pressure P2 output by the second primary transmission component 22 changes slowly, so that the second primary transmission component 22 can continuously and stably output the second pressure P2, and the second power source 12 does not need to work all the time, which is also conducive to improving the service life of the second power source 12. The first gas storage 50 and the second gas storage 52 can be containers suitable for storing gas, such as gas tanks.

[0036] Referring to FIG. 4, in some embodiments, the first primary transfer assembly 20 is also connected to the atmospheric environment E, and the first primary transfer assembly 20 selectively communicates the first gas storage 50 with the first secondary transfer assembly 30, the second secondary transfer assembly 32, or the atmospheric environment E. When the first primary transfer assembly 20 communicates the first gas storage 50 with the first secondary transfer assembly 30, the first primary transfer assembly 20 outputs the first pressure PI to the first secondary transfer assembly 30; when the first primary transfer assembly 20 communicates the first gas storage 50 with the second secondary transfer assembly 32, the first primary transfer assembly 20 outputs the first pressure PI to the second secondary transfer assembly 32; when the first primary transfer assembly 20 communicates the first gas storage 50 with the atmospheric environment E, the first pressure PI in the first gas storage 50 can be released into the atmospheric environment E. For example, when the first pressure PI in the first gas storage 50 is too high, the first pressure PI in the first gas storage 50 can be partially released by communicating the first gas storage 50 with the atmospheric environment E. In some embodiments, the gas pressure supply system 100 can further include a first gas pressure sensing device 60. The first gas pressure sensing device 60 can sense the pressure value of the first pressure PI in the first gas storage 50. When the sensed pressure value is greater than or equal to a first preset value, the first primary transfer assembly 20 communicates the first gas storage 50 with the atmospheric environment E, thereby partially releasing the first pressure PI in the first gas storage 50. It can be understood that the first pressure PI in the first gas storage 50 can be accurately adjusted by controlling the time length of the communication between the first gas storage 50 and the atmospheric environment E. In addition, the sensed pressure value of the first gas storage 50 can also be used to control the first power source 10 to work or stop working. For example, when the sensed pressure value is less than a second preset value, it indicates that the pressure value of the first pressure PI in the first gas storage 50 is insufficient, at which time the first power source 10 can continue to work to increase the pressure value of the first pressure PI.

[0037] Further, the second primary transfer component 22 is also connected to the atmospheric environment E. The second primary transfer component 22 selectively communicates the second gas storage component 52 with the second secondary transfer component 32, the first secondary transfer component 30, or the atmospheric environment E. When the second primary transfer component 22 communicates the second gas storage component 52 with the second secondary transfer component 32, the second primary transfer component 22 outputs the second pressure P2 to the second secondary transfer component 32; when the second primary transfer component 22 communicates the second gas storage component 52 with the first secondary transfer component 30, the second primary transfer component 22 outputs the second pressure P2 to the first secondary transfer component 30; when the second primary transfer component 22 communicates the second gas storage component 52 with the atmospheric environment E, the second pressure P2 in the second gas storage component 52 can be released to the atmospheric environment E. For example, when the absolute value of the pressure value of the second pressure P2 in the second gas storage component 52 is too high, the second gas storage component 52 can be partially released by communicating the second gas storage component 52 with the atmospheric environment E. In some embodiments, the gas supply system can further include a second gas pressure sensing device 62. The second gas pressure sensing device 62 can sense the pressure value of the second pressure P2 in the second gas storage component 52, so that the second primary transfer component 22 can be controlled to communicate the second gas storage component 52 with the atmospheric environment E based on the sensed pressure value. In addition, the pressure value sensed by the second gas pressure sensing device 62 can also be used to control the second power source 12 to work or stop working. The first gas pressure sensing device 60 and the second gas pressure sensing device 62 can be pressure sensors.

[0038] In some embodiments, the first secondary transfer component 30 can also communicate with the atmospheric environment E, and the first secondary transfer component 30 selectively communicates the first output end 40 with the first primary transfer component 20, the second primary transfer component 22, or the atmospheric environment E. When the first secondary transfer component 30 communicates the first output end 40 with the first primary transfer component 20, the first primary transfer component 20 outputs the first pressure PI to the first output end 40; when the first secondary transfer component 30 communicates the first output end 40 with the second primary transfer component 22, the second primary transfer component 22 outputs the second pressure P2 to the first output end 40; when the first secondary transfer component 30 communicates the first output end 40 with the atmospheric environment E, the first output end 40 outputs a third pressure, which is the atmospheric pressure. For example, the first output end 40 outputs the first pressure PI to complete the fluid loading of the target object, and subsequently the first output end 40 can output the third pressure to stop the fluid loading. For another example, the first output end 40 outputs the second pressure P2 to complete the adsorption fixation of the target object, and after the detection of the target object is completed, the first output end 40 can output the third pressure to stop the adsorption of the target object, so that the target object can be detached.

[0039] Further, the second secondary transmission component 32 is also in communication with the atmospheric environment E, and the second secondary transmission component 32 selectively communicates the second output end 42 with the second primary transmission component 22, the first primary transmission component 20 or the atmospheric environment E. When the second secondary transmission component 32 communicates the second output end 42 with the second primary transmission component 22, the second primary transmission component 22 outputs the second pressure P2 to the second output end 42; when the second secondary transmission component 32 communicates the second output end 42 with the first primary transmission component 20, the first primary transmission component 20 outputs the first pressure PI to the second output end 42; when the second secondary transmission component 32 communicates the second output end 42 with the atmospheric environment E, the second output end 42 outputs a third pressure, which is the atmospheric pressure. For example, after the second output end 42 outputs the first pressure PI to complete the fluid loading of the target object, the second output end 42 can output the third pressure to stop the fluid loading.

[0040] When the first secondary transmission component 30 and the second secondary transmission component 32 are also in communication with the atmospheric environment E, the outputs of the first output end 40 and the second output end 42 can also include the following cases: fifth, when the first secondary transmission component 30 communicates with the first primary transmission component 20 and the second secondary transmission component 32 communicates with the atmospheric environment E, the first output end 40 outputs the first pressure PI and the second output end 42 outputs the third pressure; sixth, when the first secondary transmission component 30 communicates with the atmospheric environment E and the second secondary transmission component 32 communicates with the second primary transmission component 22, the first output end 40 outputs the third pressure and the second output end 42 outputs the second pressure P2; seventh, when the first secondary transmission component 30 communicates with the second primary transmission component 22 and the second secondary transmission component 32 communicates with the atmospheric environment E, the first output end 40 outputs the second pressure P2 and the second output end 42 outputs the third pressure; eighth, when the first secondary transmission component 30 communicates with the atmospheric environment E and the second secondary transmission component 32 communicates with the first primary transmission component 20, the first output end 40 outputs the third pressure and the second output end 42 outputs the first pressure PI; ninth, when the first secondary transmission component 30 and the second secondary transmission component 32 both communicate with the atmospheric environment E, the first output end 40 outputs the third pressure and the second output end 42 outputs the third pressure. That is, the outputs of the first output end 40 and the second output end 42 can be divided into nine cases.

[0041] An embodiment of the present application further provides a gas supply method, which can be applied to the above-mentioned gas supply device. The sequence of steps of the above-mentioned method can be changed according to different needs, and some steps can be omitted or combined. The above-mentioned gas supply method comprises the following steps:

[0042] Step S1, start the first power source 10, and the first power source 10 outputs the first pressure PI to the first output end 40 through the first primary transmission component 20 and the first secondary transmission component 30.

[0043] In some embodiments, the first power source 10 is provided with a first gas storage member 50. The first power source 10 generates a first pressure P1 in the first gas storage member 50, and the first gas storage member 50 outputs the first pressure P1 to the first output 40 via the first primary transmission assembly 20 and the first secondary transmission assembly 30.

[0044] Step S2, the second power source 12 is started, and the second power source 12 outputs a second pressure P2 via the second primary transmission assembly 22 and the second secondary transmission assembly 32.

[0045] In some embodiments, the second power source 12 is provided with a second gas storage member 52.

The first valve port 2011 is connected to the first power source 10, the second valve port 2012 is connected to the first interface 2021, the third valve port 2013 is connected to the atmospheric environment E, and the first valve port 2011 selectively communicates with the second valve port 2012 or the third valve port 2013. The first interface 2021 is connected to the second valve port 2012, the second interface 2022 is connected to the first secondary transmission assembly 30, and the third interface 2023 is connected to the second secondary transmission assembly 32.

[0060] The first secondary transmission assembly 30 comprises a second three-way valve 301 and a third three-way valve 302, and the second three-way valve 301 is connected between the first primary transmission assembly 20 and the third three-way valve 302.

[0062] The first fluid storage module 1011 includes a first fluid storage member 1012 and a first fluid transfer member 1013.

The second two-way valve 1018 is arranged between the second reagent container 1013A and the first target slide C1. In some embodiments, when the first output pipeline 40A outputs the second pressure P2, i.e., negative pressure, the first two-way valve 1017 is opened to connect the first reagent container 1012A and the second reagent container 1013A, so that the reagent in the first reagent container 1012A is transferred to the second reagent container 1013A under the action of negative pressure through the first two-way valve 1017. The volume of the reagent transferred to the second reagent container 1013A can be adjusted by controlling the opening time of the first two-way valve 1017.

[0063] The structure of the second fluid path system 102 is the same as that of the first fluid path system 101. The process of controlling the loading of reagent to the second target slide C2 by negative pressure and positive pressure in sequence is the same as the process of controlling the loading of reagent to the first target slide C1, which is not described herein.

[0064] Since the first output pipeline 40A and the second output pipeline 42A have three output states respectively, the entire gas pressure supply system 100 has a total of 3 2 i.e., nine output states.

[0065] Example 2

[0066] Please refer to FIG. 8, which omits the first liquid path system 101 and the second liquid path system 102. The difference between the embodiment 1 and the embodiment 2 is that the number of the first secondary transmission components 30 and the first output pipelines 40A is two respectively and they are connected one by one. The first joint 202 of the first secondary transmission component 30 is a five-way joint, and the number of the second interfaces 2022 is two.

The first joint 202 of the second secondary transmission component 32 is a five-way joint, and the number of the second interfaces 2022 is two. The two second interfaces 2022 are connected to the two second secondary transmission components 32 respectively.

[0067] Therefore, the embodiment outputs pressure through four output ends. Since each first output pipeline 40A and each second output pipeline 42A has three output states respectively, the whole gas pressure supply system 100 has 3 4 That is, eighty-one output states.

[0068] Embodiment 3

[0069] Please refer to FIG. 9. The difference between the embodiment 1 and the embodiment 2 is that the first primary transmission component 20 and the second primary transmission component 22 are both single three-way valves.

The first fluid path system 101 further includes a first fluid selection member 1015, which is a rotary valve 1015A, and a first suction member 1016, which is a slide platform 1016A. The first fluid path system 101 further includes a fourth three-way valve 1019, which selectively communicates the first output pipeline 40A with the first reagent container 1012A or the slide platform 1016A. When the fourth three-way valve 1019 communicates the first output pipeline 40A with the first reagent container 1012A, the rotary valve 1015A is selectively rotated to connect the reagent in a selected first fluid storage member 1012 with the first target slide C1, so that the first pressure P1 output by the first output pipeline 40A, i.e. positive pressure, can drive the selected reagent to be loaded to the first target slide C1, so that the reagent can be subjected to biochemical reaction in the first target slide C1. When the fourth three-way valve 1019 communicates the first output pipeline 40A with the slide platform 1016A, the second pressure P2 output by the first output pipeline 40A, i.e. negative pressure, can suck the first target slide C1 to the slide platform 1016A.
