However, the structure adopted in its detection scheme is an unfolded structure, which occupies a large area, and each bracket is connected only by a single rod structure, which is prone to breakage. In order to avoid this problem, a typing detection device for Helicobacter pylori is provided. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides the following technical solutions:

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0019] A Chinese patent with announcement number CN219496403U discloses a typing detection device for Helicobacter pylori, which performs typing detection by setting up multiple arms and judges the final result according to the display status of the typing detection. However, the structure adopted in its detection scheme is an unfolded structure, which occupies a large area, and each bracket is only connected by a single rod structure, which is prone to breakage.

[0020] To avoid the above problems, see Figure 1-Figure 3 , a typing detection device for Helicobacter pylori is provided, comprising: an outer cylinder 10 and an inner column 20 penetrating the inside of the through cavity 11.

[0021] Specifically, a through cavity 11 is opened inside the outer tube 10, and the outer tube 10 has a plurality of inner flow channels 131. A liquid trough 21 is opened at one end of the inner column 20, and the inner wall of the liquid trough 21 has side holes 22 corresponding to the positions of the inner flow channels 131. The inner flow channel 131 has a connected slot 132 at one end away from the side holes 22, and a test piece of Helicobacter pylori for detection is inserted into the slot 132. When the inner column 20 moves upward until the side hole 22 is connected with the inner flow channel 131, the test liquid in the liquid trough 21 contacts the test piece along the inner flow channel 131.

[0022] Before injecting the test liquid into the through cavity 11, the inner column 20 is pulled downward until the side hole 22 is located below the inner flow channel 131, and then the test specimens are inserted inward from different slots 132, and the test liquid is injected into the through cavity 11, and the liquid enters the liquid tank 21. After the liquid injection is completed, the inner column 20 is pushed upward, and the inner column 20 moves up and enters the inner flow channel 131 through the side hole 22, and contacts the specimen in the slot 132 through the inner flow channel 131. The fluorescent reaction generated by the specimen after contact is used to determine whether the test liquid contains Helicobacter pylori and the type of Helicobacter pylori.

[0023] In order to ensure the stability of the liquid flow in the inner flow channel 131 and reduce the material consumption of the overall production, please refer to Figures 1 to 3 The outer wall of the outer tube 10 is integrally formed with a plurality of protrusions 13, the inner flow channel 131 is arranged inside the protrusion 13, one end of the slot 132 away from the inner flow channel 131 penetrates to the outside of the protrusion 13, and the other end of the inner flow channel 131 penetrates to the inside of the through cavity 11.

[0024] The arrangement of the protrusion 13 provides a location for the inner flow channel 131 , reduces the design thickness of the entire outer cylinder 10 , and reduces the consumption of production materials of the device.

[0025] In order to prevent the liquid in the liquid tank 21 from being affected by the external environment and leaking, please refer to Figures 1 to 3 A partition 12 is fixed at the entrance of the through cavity 11, and a slot 121 is provided on the surface of the partition 12. A partition 23 is fixed to the end of the liquid tank 21 close to the partition 12, and a slot 231 is provided on the surface of the partition 23. When the inner column 20 moves until the partition 23 is inserted into the interior of the slot 121, the partition 12 is inserted into the interior of the slot 231 to form a closure for the liquid tank 21.

[0026] The buckling between the partition 12 and the partition 23 forms the purpose of limiting the push position and sealing at the top. When the test piece is inserted into the slot 132, the slot 132 is sealed by the test piece, leaving some tiny gaps for liquid to precipitate. The precipitated liquid contacts the test piece and is detected by the test piece. In order to prevent the precipitated liquid from leaking, please refer to Figures 1 to 3 A pressing piece 133 is provided on the outer surface of the protrusion 13 . When the test piece is inserted into the slot 132 , the pressing piece 133 presses the entrance of the slot 132 .

[0027] The entrance of the slot 132 is sealed by the pressing piece 133 to prevent the liquid from flowing out of the slot 132 .

[0028] In order to limit the position of the inner column 20 to avoid the problem of the inner column 20 falling before use, please refer to Figures 1 to 4 A recessed portion 24 is formed on the outer side of one end of the inner column 20 away from the liquid tank 21, and a limiting member 14 is detachably fixed to the inner wall of the outer cylinder 10. The limiting member 14 is inserted into the interior of the recessed portion 24 and rotates and / or moves linearly along the outer wall of the recessed portion 24.

[0029] The limit member 14 performs position restriction inside the recessed portion 24, which can limit the maximum moving distance of the inner column 20, and can also limit the lowest descending position and the highest ascending position of the inner column 20, thereby ensuring that the inner column 20 can be supported before use. After the liquid to be tested is injected into the inner portion, it is only necessary to place the bottom of the inner column 20 on a support such as a table. Due to its own weight, the outer cylinder 10 can ensure that the partition 12 and the partition 2 23 are pressed together to ensure the normal use of the structural parts.

[0030] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
