Description

Technical Field

[0001] This utility model relates to the field of medical diagnostic equipment technology, and in particular to a Helicobacter pylori detector. Background Technology

[0002] In the field of gastrointestinal disease research and treatment, the detection of Helicobacter pylori (Hp) plays a crucial role. Hp is a Gram-negative bacterium that can survive in the extremely acidic environment of the human stomach and is closely related to the development of chronic gastritis, peptic ulcers, and even gastric cancer. Given its potential threat to human health, early diagnosis and treatment of Hp infection are of paramount importance.

[0003] Currently, there are various methods for detecting *Helicobacter pylori* (Hp), encompassing both invasive and non-invasive categories. Invasive methods, such as endoscopic biopsy, allow direct observation of the gastric mucosa and sample collection, but the patient experience is poor and carries certain risks of trauma. Non-invasive methods, such as the urea breath test, are the gold standard widely used in clinical practice due to their non-invasive and rapid nature. This test is based on the fact that *Hp* secretes large amounts of urease, which breaks down ingested urea into carbon dioxide and ammonia. The marker carbon isotopes (such as C2O3) in the subject's exhaled breath are measured. 14 Or C 13 The content of Hp indirectly reflects the presence of Hp.

[0004] During the testing process, the patient first collects their exhaled breath on a special breathalyzer card, which is then handed over to medical staff for further processing. At this point, the sealing stickers on both sides of the breathalyzer card need to be removed so that it can be inserted into a specialized testing device for CT scans. 14 Radiation testing. This process, though seemingly simple, actually increases the workload of frontline medical staff, and the removal of the sticker exposes the breathalyzer to the air for a brief period, theoretically posing a risk of external contaminants interfering with the test results. Utility Model Content

[0005] The purpose of this invention is to provide a Helicobacter pylori detector that can automatically peel off the sticker inside the instrument, reducing the workload of medical staff and avoiding exposure to air to prevent interference with test results.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a Helicobacter pylori detector, comprising a housing, wherein a waste chamber is provided in the lower part and a detection chamber is provided in the upper part of the housing, a drawer opening is provided on the front side of the waste chamber, a waste drawer that can be pulled out from the drawer opening is provided in the waste chamber, a drop opening communicating with the waste chamber is provided at the bottom rear of the detection chamber, a vertical insertion opening is provided on the upper front side of the housing, an insertion channel communicating with the vertical insertion opening is provided on the rearward inner wall of the detection chamber, and a Gellé counter is provided on both sides of the detection chamber behind the insertion channel;

[0007] The detection chamber has sliding rails on both sides of the insertion channel, each sliding rail is slidably connected to a connecting piece, and each sliding rail is equipped with a drive motor for driving the corresponding connecting piece to slide. Each connecting piece is equipped with an electromagnet on the side away from the insertion channel, and each connecting piece is provided with a sliding channel on the side facing the insertion channel. Each sliding channel is slidably connected to a hollow negative pressure shell, each hollow negative pressure shell is made of a metal material that can be attracted by magnetic force, and a support spring is provided between each hollow negative pressure shell and the corresponding connecting piece. Each hollow negative pressure shell has a negative pressure hole on the side facing the insertion channel. A negative pressure pump is installed in the detection chamber, and each hollow negative pressure shell is connected to the inlet end of the negative pressure pump through a negative pressure hose.

[0008] The upper end of the housing is provided with a display screen and multiple operation buttons. An integrated circuit board is provided inside the detection chamber. Each Geller counter, each drive motor, each electromagnet, the negative pressure pump, the display screen, and each operation button are electrically connected to the integrated circuit board.

[0009] By adopting the above technical solution, after the exhalation card is inserted into the vertical insertion port, the drive motor drives the connecting piece to move to the head position of the exhalation card. The electromagnet is de-energized, and under the action of the support spring, the hollow negative pressure shell is pushed outward to contact the sticker on the side of the exhalation card. The negative pressure pump is activated, creating negative pressure at the negative pressure hole to attract the sticker. Then, the electromagnet is energized again, generating magnetism to attract the hollow negative pressure shell, and the drive motor drives the hollow negative pressure shell to pull the sticker forward, causing the hollow negative pressure shell to attract the sticker and tear it off the exhalation card. Subsequently, the drive motor drives the hollow negative pressure shell to pull the sticker backward to above the drop opening. Finally, the negative pressure pump stops working, the negative pressure is lost, and the sticker falls into the waste drawer. Then, the Geller counter records the C on the exhalation card. 14 By conducting the test, Helicobacter pylori can be detected indirectly.

[0010] A further feature of this invention is that a printer electrically connected to the integrated circuit board is provided inside the detection cavity, and a printing outlet that matches the paper output port of the printer is provided on the side wall of the housing.

[0011] A further feature of this invention is that each sliding track is rotatably connected to a threaded shaft, each drive motor is installed at one end of the corresponding sliding track and its power output shaft is connected to the corresponding threaded shaft, each sliding track is slidably connected to a threaded sleeve that is threadedly connected to the corresponding threaded shaft, and each connecting piece is connected to the side of the corresponding threaded sleeve facing the insertion channel.

[0012] A further feature of this invention is that: the opening edge of the free end of each sliding channel is provided with a limiting stop edge that is slidably connected to the side wall of the corresponding hollow negative pressure shell, and the edge of each hollow negative pressure shell near the end of the corresponding electromagnet is provided with a sliding edge that is slidably connected to the inner wall of the corresponding sliding channel.

[0013] A further feature of this invention is that a vertical limiting strip is provided at the rear of the detection cavity to cooperate with the vertical insertion port, and a limiting slot is provided on the front side of the vertical limiting strip.

[0014] A further feature of this invention is that a power line electrically connected to the integrated circuit board is connected to one side of the housing.

[0015] In summary, this utility model has the following beneficial effects:

[0016] Firstly, when using the breath card to test for Helicobacter pylori, this utility model eliminates the need for medical staff to manually peel off the sticker. Inserting the breath card into the instrument automatically peels off the sticker, reducing the workload of medical staff and preventing exposure to air, thus avoiding interference with the test results.

[0017] Secondly, this utility model utilizes a waste drawer to centrally store torn stickers. Only the stickers in the waste drawer need to be cleaned periodically, eliminating the need to discard the stickers separately for each test, further reducing the workload of medical staff.

Alternatively, a liquid scintillation counter can be used to detect C on the breathalyzer. 14 .

[0029] Inside the detection cavity 12, a sliding track 5 is provided on both sides of the insertion channel 2, extending backward. The cross-section of the sliding track 5 is U-shaped with the opening facing the insertion channel 2. A threaded shaft 51 is rotatably connected to each sliding track 5, and a threaded sleeve 52 is slidably connected to the corresponding threaded shaft 51. A connecting piece 53 is connected to the side of each threaded sleeve 52 facing the insertion channel 2. A drive motor 54 is installed at one end of each sliding track 5 to drive the corresponding connecting piece 53 to slide. The power output shaft of each drive motor 54 is connected to the corresponding threaded shaft 51. The drive motor 54 drives the threaded shaft 51 to rotate, which in turn drives the connecting piece 53 to slide back and forth.

[0030] Each connecting piece 53 has an electromagnet 6 installed on the side away from the insertion channel 2. Each connecting piece 53 has a U-shaped sliding channel 55 on the side facing the insertion channel 2. Each sliding channel 55 is slidably connected to a hollow negative pressure shell 7. The opening edge of the free end of each sliding channel 55 is provided with a limiting stop 56 that is slidably connected to the side wall of the corresponding hollow negative pressure shell 7. The edge of each hollow negative pressure shell 7 near the end of the corresponding electromagnet 6 is provided with a ring that is slidably connected to the inner wall of the corresponding sliding channel 55. The sliding edge 71 is connected to each hollow negative pressure shell 7, which is made of a metal material that can be attracted by magnetic force.

[0032] Working principle: After the exhalation card is inserted into the vertical insertion port 16, the drive motor 54 drives the connecting piece 53 to move to the head position of the exhalation card. The electromagnet 6 is de-energized, and under the action of the support spring 57, the hollow negative pressure shell 7 is pushed outward to contact the sticker on the side of the exhalation card. The negative pressure pump 73 is activated, so that negative pressure is generated at the negative pressure hole 72 to attract the sticker. Then the electromagnet 6 is energized again, generating magnetism to attract the hollow negative pressure shell 7, and the drive motor 54 drives the hollow negative pressure shell 7 to pull the sticker forward, so that the hollow negative pressure shell 7 attracts the sticker and peels it off the exhalation card. Then the drive motor 54 drives the hollow negative pressure shell 7 to pull the sticker backward to move it above the drop port 15. Finally, the negative pressure pump 73 stops working and loses negative pressure, causing the sticker to fall into the waste drawer 14. Then the Geller counter 4 checks the C on the exhalation card. 14 By conducting the test, Helicobacter pylori can be detected indirectly.
