The first and second liftout portions 72 will be described in detail in fig. 2.
FIG. 2 is a schematic view of a sample testing device including a housing. As shown in FIG. 2, optionally, the sample testing device further includes a housing 90, which may be made of plastic, and for clarity, the components of the housing shown in FIG. 2 are marked with thicker lines. The housing 90 comprises a sample inlet 91 corresponding to the opening of the sample chamber 10 for injecting a sample liquid. The sample liquid may fill the sample processing chamber 20 from below up the first conduit 51 shown in fig. 2. In addition, the housing 90 further has a first pressing portion 92 and a second pressing portion 93, and the first pressing portion 92 is linked with the first ejecting portion 71 to pierce the first container 41. The second pressing portion 93 is linked with the second ejecting portion 72 for piercing the second container 42. The first pressing portion 92 and the first ejecting portion 71 may be integrally formed or assembled, and the second pressing portion 93 and the second ejecting portion 72 may be integrally formed or assembled.

Specifically, the reaction solution may be a reaction buffer solution or a reaction reagent, wherein the reaction buffer solution needs to be combined with the lyophilized pellet to dissolve the lyophilized pellet, and is mixed with the first mixed solution to react. For example, after the tester punctures the second container 42 by hand or by machine, the reaction buffer solution in the second container enters the reaction chamber 30 along the fourth pipeline 54, and is mixed with the lyophilized pellet, so that the lyophilized pellet is dissolved. For another example, in other cases, the second container 42 stores the reaction reagent, and the reaction reagent in the second container 42 is directly extruded into the reaction chamber 30 without the lyophilized powder pellets in the reaction chamber 30. Optionally, the sample chamber 10 is tapered, and a cover for sealing the sample chamber 10 is disposed at the top of the sample chamber 10, so that the sample liquid in the sample chamber 10 in the sealed state cannot flow along the first pipeline 51.

Optionally, in the use state, the position where the second pipeline 52 is communicated with the sample processing chamber 20 is higher than the position where the first pipeline 51 is communicated with the sample processing chamber 20. That is, the second pipe 52 communicates with the sample treatment chamber 20 at a position closer to the air hole of the reaction chamber 20 than the first pipe 51 communicates with the sample treatment chamber 20.
Optionally, the sample detection device further comprises an air hole blocking device for blocking at least one of the first air hole and the second air hole. The number of the plugging means is two, for example, for plugging the first air hole 61 and the second air hole 62, respectively.

In the embodiment of the invention, a mode of integrating sample processing, sample mixing and sample detection is adopted, and the control of the pressure device and the conveying pipeline is utilized to achieve the purposes of fully mixing and processing samples and efficiently and accurately detecting the samples, so that the technical problems that in the prior art, sample storage, sample processing and detection cannot be uniformly carried out, and the detection efficiency is low are solved.
Example two
According to another aspect of the embodiments of the present invention, there is also provided a sample detection method, including: injecting the sample processing liquid into the sample processing chamber 20; mixing the sample treatment solution with a sample to obtain a first mixed solution; injecting the first mixed solution into a sample reaction bin 30; mixing the first mixed solution with a reaction solution to obtain a second mixed solution; and generating a detection result according to the second mixed solution.
Fig. 3 is a flow chart of a sample testing method according to an embodiment of the present invention, as shown in fig. 3, including:
in step S301, the sample processing liquid is injected into the sample processing chamber 20.
Specifically, the embodiment of the present invention aims to realize processes of storing a sample and analyzing the sample after the sample is collected from a case or a sample source, so that in order to perform a preliminary sample liquid treatment on the collected sample liquid, a sample treatment liquid needs to be mixed with the sample to achieve a purpose of subsequently treating the sample.
As shown in fig. 1, the air hole of the reaction chamber 30 is kept closed, the air hole of the sample processing chamber 20 is opened, the first container is pressed, the first ejector pierces the first container, and the sample processing liquid in the first container, which is required to be mixed with the collected sample and analyzed, enters the sample processing chamber 20 through the second pipe 52, and the air hole is opened in order to inject the sample processing liquid into the processing chamber by using the atmospheric pressure in the pipe.
Optionally, the injecting the sample processing liquid into the sample processing bin 20 includes: opening the first air vent 61 of the sample processing cartridge 20; the sample processing liquid is injected from the sample processing liquid container to the sample processing chamber 20.
It should be noted that the container in which the sample processing solution is located may be an aluminum foil bag, and the aluminum foil facilitates penetration of a push-out portion (e.g., a broken needle) to form a vacuum to release the sample processing solution loaded in the aluminum foil bag.
Step S302, mixing the sample treatment fluid with a sample to obtain a first mixed solution.
As shown in fig. 3, the sample chamber 10 is inflated by pressing the pressure supply portion 80, so that the sample enters the sample processing chamber 20 through the first pipe 51, and fills the sample processing chamber 20 from bottom to top, but does not overflow through the opening of the second pipe 52. At this time, the air holes of the first container and the second container are closed, and the sample processing liquid does not flow down along the third pipe 53.
Optionally, before mixing the sample treatment solution with the sample to obtain a first mixed solution, the method further includes: the sample is added to the sample bin 10.
Specifically, the sample chamber 10 may be a conical structure, which is convenient for the inspector to put the collected sample liquid into the sample chamber 10.
Step S303, the first mixed liquid is injected into the sample reaction chamber 30.
Specifically, as shown in fig. 1, the first air hole of the sample processing chamber 20 is closed, and the second air hole of the reaction chamber 30 is opened, so that the liquid in the sample processing chamber 20 enters the reaction chamber 30 due to the air pressure, wherein the liquid in the sample processing chamber 20 is the first mixed liquid, that is, the first mixed liquid is injected into the reaction chamber 30 to wait for further reaction and detection through the control manner of the air pressure of the air holes.
Step S304, mixing the first mixed solution with a reaction liquid to obtain a second mixed solution.
Specifically, after the first mixed liquid enters the reaction chamber 30, the reaction liquid also needs to be injected into the reaction chamber 30 to react with the first mixed liquid, so as to obtain the detection result. The container in which the reaction solution is located may be a second container, such as an aluminum foil bag, and the aluminum foil is punctured by the same needling method as the sample processing solution, so that the reaction solution is pneumatically transferred into the reaction chamber 30.
Specifically, as shown in fig. 1, by pressing the pressure supply part 80 multiple times while the first air hole in the sample processing chamber 20 is closed, the air can enter the reaction chamber 30 only through the first and third pipes 51 and 53, so that the sample processing solution and the reaction reagent are sufficiently mixed. In this process, the first container 41 and the second container 42 are kept stationary after the liquid is punctured and pressed out, and the air pressure closes the liquid discharge pipes of the first container 41 and the second container 42, so that the liquid is prevented from flowing back.
Optionally, when the reaction solution is the reaction buffer solution, the method further includes: the reaction buffer was mixed with the lyophilized pellet and dissolved.
Specifically, the reaction solution may be a reaction buffer or a reaction reagent, wherein the reaction buffer needs to be combined with the lyophilized pellet and mixed with the first mixture. For example, after the inspector punctures the second container 42, the reaction buffer solution in the second container enters the reaction chamber 30 along the fourth pipeline 54 and is mixed with the lyophilized pellet to dissolve the lyophilized pellet. For another example, in other cases, the second container 42 stores the reaction reagent, and the reaction reagent in the second container 42 is directly extruded into the reaction chamber 30 without the lyophilized powder pellets in the reaction chamber 30.
Step S305, generating a detection result according to the second mixed solution.
Specifically, a detection module may be disposed in the reaction bin 30, and colorimetric detection or turbidity detection is performed on a detection result of the reaction bin 30, so as to detect a reaction result in the reaction bin 30, and the detection result may be fed back to the intelligent terminal carrier, where the intelligent terminal carrier may be a PC terminal or a mobile terminal with a detection device slot.
FIG. 4 is a flow chart showing the operation steps of the present invention. As shown in fig. 4, the operation steps of the present invention include the following steps:
step S401, keeping the air hole of the reaction chamber 30 in a closed state, opening the second air hole 61 of the sample processing chamber 20, after pressing down the first pressing part of the shell, piercing the first container 41 by the first ejector 71, and allowing the sample processing liquid in the first container 41 to enter the sample processing chamber 20 through the second pipeline 52;
step S402, add the sample into the sample chamber, as shown in fig. 2, at this time, the second air hole 62 is in a closed state, and the third pipeline 53 is not connected, so that the sample stays in the sample chamber 10.
In step S403, the sample chamber 10 is inflated by pressing the pressure providing part 80 of fig. 3, so that the sample enters the sample processing chamber 20 through the first pipeline 51, and fills the sample processing chamber 20 from bottom to top, but does not overflow through the opening of the second pipeline. The air holes of the first container 41 and the second container 42 are now kept closed, and the sample processing liquid does not flow down the third pipe. The pressure providing part 80 is pressed several times, and the processing liquid and the sample in the sample processing chamber 20 are sufficiently mixed.
Step S404, closing the first air hole 61 of the sample processing chamber 20, opening the second air hole 62 of the reaction chamber, and allowing the liquid in the sample processing chamber 20 to enter the reaction chamber 30 due to the air pressure.
Step S405, puncturing the second container 42, so that the reaction liquid in the second container enters the reaction chamber 30 along the fourth pipeline, and is mixed with the lyophilized pellet in the reaction chamber, so that the lyophilized pellet is dissolved. In other cases, the second container 42 stores the reagents, and the reagents in the second container 42 are directly extruded into the reaction chamber 30 without the need of freeze-dried powder pellets in the reaction chamber.
In step S406, after the pressure providing part is pressed multiple times, the gas can enter the reaction chamber only through the first and third pipelines 51 and 53 in view of the sealing of the first air hole 61 in the sample processing chamber, so that the sample processing solution and the reaction reagent are mixed sufficiently. In this process, the first container 41 and the second container 42 are kept stationary after the liquid is punctured and pressed out, and the air pressure closes the liquid discharge pipes of the first container 41 and the second container 42, so that the liquid is prevented from flowing back.
And step S407, detecting according to the reaction result.
