[0034] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of this application.

[0035] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of this application are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0036] In addition, the descriptions involving "first", "second", etc. in this application are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0037] The embodiments of this application provide a safe and fast air bag sample injection device, which solves the technical problem in the prior art that air bag sampling mostly relies on manual syringe operation and is prone to cross - contamination.

[0038] The technical solution in the embodiments of the present application for solving the above technical problems has the following general idea:

[0039] As Figures 1 - 8 shown, the present application provides a safe and fast airbag 1 sampling device, including:

[0040] An airbag 1, which is provided with an air inlet port 103 and an air outlet port 101;

[0041] A sampling fixing seat 2, which is connected to the air outlet port 101;

[0042] An adapter seat 7, on which a sampling needle 6 is installed at the Luer end 701 of the adapter seat 7;

[0043] A needle fixing nut 5, the inner side of the needle fixing nut 5 cooperates with the adapter seat 7 to fix the sampling needle 6, and the outer side of the needle fixing nut 5 cooperates with the sampling fixing seat 2.

[0044] The sampling needle 6 is fixed on the sampling fixing seat 2 through the needle fixing nut 5 and the adapter seat 7, and then the sampling fixing seat 2 with the sampling needle 6 is inserted into the airbag 1. The experimenter does not need to operate the sampling needle 6, avoiding human operation errors, reducing the working pressure, and making the maintenance and replacement of the sampling needle 6 more convenient.

[0045] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0046] Specifically, the adapter seat 7 is a Luer connector.

[0047] Preferably, as Figure 2 、 Figure 6 shown, a groove is formed on the side of the sampling fixing seat 2 and a detection switch 3 is installed. The detection switch 3 is a micro switch, and a small cover plate 4 is detachably installed in the groove. First, the detection switch 3 is installed in the groove so that the detection switch 3 can detect whether it is fully docked with the sampling fixing seat 2 in the sampling fixing seat 2. When the sampling fixing seat 2 and the airbag 1 are docked, the detection switch 3 can detect the air outlet port 101, and then the next step can be carried out, improving the safety of the operation.

[0048] Preferably, as Figure 5 、 Figure 7 、 Figure 8 shown, a diaphragm 102 is provided at the air outlet port 101 of the airbag 1. Before and when the sampling needle 6 is inserted, the diaphragm 102 made of silica gel can isolate and protect the airbag 1, avoiding external objects from contaminating the inside of the airbag 1. The inlet of the sampling fixing seat 2 is a tapered port 201, which is convenient for the experimenter to insert the sampling fixing seat 2 and the sampling needle 6.

[0049] Preferably, as Figures 1 - 4 shown, a pipe 9 is connected to the pipe connection end 702 of the adapter base 7, and a double ferrule nut 8 is provided between the adapter base 7 and the pipe 9. The double ferrule nut 8 fixes the pipe 9 on the adapter base 7.

[0050] Fixing the pipe 9 on the adapter base 7 by the double ferrule nut 8 facilitates later maintenance, disassembly and replacement of the pipe 9.

[0051] Furthermore, a plate body 202 is provided on the side of the sample injection fixing base 2. When installing the pipe 9, the sample injection needle 6 and the needle fixing nut 5, the experimenter holds or presses the plate body 202, providing a force application position for the experimenter and simplifying the working difficulty.

[0052] Preferably, the air inlet port 103 and the air outlet port 101 are respectively located at both ends of the air bag 1. The air outlet port 101 of the air bag 1 is arranged along its length direction. The air inlet port 103 and the air outlet port 101 of the air bag 1 are not parallel. The air inlet and outlet of the air bag 1 being at both ends facilitates the collection and transportation of samples. The air inlet port 103 is inclined, optimizing the sampling angle and making sampling convenient and labor-saving.

[0053] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications once they learn the basic creative concept. Therefore, the appended claims are intended to be construed to include the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0054] Obviously, those skilled in the art can make various changes and deformations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and deformations.
