Description

Technical Field

[0001] The present invention relates to the technical field of Helicobacter pylori detection, in particular to a Helicobacter pylori detector with dual detection positions. Background Art

[0002] The Helicobacter pylori (H. pylori) detector is a medical device used to rapidly detect Helicobacter pylori (H. pylori) gastric infection. Designed primarily based on the ability of H. pylori to produce urease, it enables accurate diagnosis through non-invasive or minimally invasive methods. The mainstream detection technology is the urea breath test. After a patient orally ingests a capsule containing carbon-13 or carbon-14 labeled urea, if H. pylori infection is present, the urease produced breaks down the urea to release labeled carbon dioxide. The instrument then analyzes the carbon isotope content in the breath sample through mass spectrometry or infrared spectroscopy (for example, the carbon-13 breath test detects changes in δ13C values) to determine infection status. A dual-station H. pylori detector is a traditional H. pylori detector with two detection stations that can process two samples simultaneously or independently.

[0003] During testing, existing Helicobacter pylori detectors mostly collect the patient's exhaled gas through a gas collection card. After the collection is completed, the gas collection card is inserted into the detection position of the device through the detection port on the device. Since the material used for the gas collection card has a certain degree of flexibility, when the user places the gas collection card through the fixed detection port, there is a chance that the gas collection card will get stuck during the insertion process, causing damage to the gas collection card, resulting in sample loss and contamination of the device. At the same time, in order to ensure the safety of the detection module, the width of the detection port is mostly narrow. Therefore, when the user places the gas collection card, the user needs to spend a certain amount of time to align the gas collection card with the detection port, resulting in limited detection efficiency. For this reason, we propose a Helicobacter pylori detector with dual detection positions. Summary of the Invention

[0004] (1) Technical problems solved In response to the shortcomings of the existing technology, the present invention provides a Helicobacter pylori detector with dual detection positions, which solves the problem that in the existing Helicobacter pylori detection, the user places the gas collection card through a fixed detection port, and there is a chance that the gas collection card will get stuck during the insertion process, causing damage to the gas collection card, resulting in sample loss and contamination of the equipment. At the same time, in order to ensure the safety of the detection module, the width of the detection port is mostly designed to be narrow. Therefore, when the user places the gas collection card, the user needs to spend a certain amount of time to align the gas collection card with the detection port, resulting in limited detection efficiency.

[0025] Among them, the electric push rod 63 is electrically connected to the fuselage 1, the damping sleeve 65 is slidingly connected to the inner wall of the guide groove, and the spring 2 67 is sleeved on the surface of the connecting column 64. The spring 2 67 can apply pressure to the fixed connecting ring 66. When the sleeve 61 applies thrust to the connecting ring 66, the setting of the spring 2 67 can make the sleeve 61 move in a specified direction within a certain range without pushing the connecting ring 66.

[0026] Among them, the number of the bayonet pins 68 is four, and the four bayonet pins 68 are arranged in a circular array with the center of the connecting ring 66 as a reference. The end of the bayonet pin 68 away from the connecting ring 66 is provided with a chamfer. By utilizing the cooperation between the bayonet pin 68 and the slot 69, when the bayonet pin 68 is inserted into the slot 69, the bayonet pin 68 can lock the position of the driving gear 58, thereby disconnecting the power transmission between the driving gear 58 and the rotating shaft 56.

[0027] Among them, the inner wall of the bracket 52 is provided with a clamping device 7, the clamping device 7 includes a constraint shaft 72, a storage cavity 71 is opened on the surface of the bracket 52, the constraint shaft 72 is rotatably connected to the inner wall of the storage cavity 71, the surface of the constraint shaft 72 is fixedly connected to a connecting frame 73, the inner side of the connecting frame 73 is fixedly connected to a rubber block 74, the bracket 52 is located on the inner wall of the storage cavity 71 and is fixedly connected to a limiting block 75, a slot 76 is opened on the inner wall of the connecting frame 73, a torsion spring 77 is installed on the inner wall of the connecting frame 73 located at the slot 76, the bracket 52 is located on the inner wall of the storage cavity 71 and a limiting groove 78 is opened, the torsion spring 77 is plugged into the inner wall of the limiting groove 78, the rubber block 74 can replace the connecting frame 73 to contact the gas collecting card, and when the connecting frame 73 is closed, the gas collecting card is clamped to ensure the stability of the gas collecting card during the detection process.

[0028] Among them, the connecting frame 73 is located inside the storage cavity 71, one end of the connecting frame 73 is arranged in an arc shape, and the upper and lower ends of the constraint shaft 72 are provided with placement grooves, and the limit block 75 is located inside the placement groove. The limit block 75 can be used to constrain the maximum rotation angle of the constraint shaft 72 to avoid the problem that the constraint shaft 72 and the connecting frame 73 rotate too much, resulting in subsequent problems of normal use.

[0029] The working principle of the present invention is as follows: when using the detector for detection, the power cord is plugged into the power interface 4, and the other end of the power cord is plugged into the 220V mains socket. After completing the connection of the power cord, turn on the switch of the fuselage 1, and the fuselage 1 is powered on. Then operate the control button 3 to observe the display screen 2 and calibrate the equipment. After completing the preparation operation, the control is controlled by the control button 3 to control the fuselage 1. The fuselage 1 controls the sample delivery device 5 to pop up through the internal chip, and then the gas collection card for collecting the sample is placed in the sample delivery device 5. After the placement is completed, operate the control button 3 so that the fuselage 1 controls the sample delivery device 5 to send the gas collection card into the detection area. When the gas collection card enters the detection area, operate the control button 3 to make the detection module of the equipment work. The equipment detection module measures the carbon 13 or carbon 14 labeled CO2 content of the sample in the gas collection card through mass spectrometry or infrared spectroscopy. Then the fuselage 1 determines whether the sample is infected with Helicobacter pylori through the CO2 content; When placing the gas collection card, the user can press the dual detection position synchronous eject button according to the use requirements, or select the button on the left or right side of the synchronization button according to the required detection position, and then the fuselage 1 controls the motor 54 to work through the chip under the user's operation. The motor 54 is energized to drive the transmission gear 55, and the transmission gear 55 is engaged with the driven gear 57. The driven gear 57 drives the rotating shaft 56 to rotate. When the rotating shaft 56 rotates, the load pin 510 pressed by the spring 59 drives the driving gear 58. The driving gear 58 is engaged with the rack 511 under the action of the rotating shaft 56. The rack 511 drives the bracket 52 outward under the action of the driving gear 58, and the bracket 52 is mounted on the mounting bracket. Under the guidance of 51 and the protrusion 53, the mounting bracket 51 is gradually slid out. When the bracket 52 is completely slid out, the chip automatically controls the motor 54 to cut off the power, and then the user can put the gas collection card into the pop-up bracket 52; after the placement is completed, the control button 3 is operated, and the fuselage 1 cooperates with the chip to control the motor 54 to work. The motor 54 runs and sends the gas collection card into the detection area in reverse according to the above steps; by setting the sample delivery device 5, when the user places the gas collection card, the device can send the placement area out to facilitate the user to place the sample, so as to avoid the problem that the gas collection card is prone to jamming when the user places the gas collection card and the placement efficiency is limited by the detection port, so as to improve the smoothness and placement efficiency of the gas collection card during the placement process; In addition, when the user uses a separate sample feeding device 5 and presses the eject button of the left detection position, the chip inside the fuselage 1 controls the right electric push rod 63 to work, and the right electric push rod 63 cooperates with the fixed plate 62 to push the sleeve 61. The sleeve 61 pushes the connecting ring 66 in the direction of the right driving gear 58 under the cooperation of the connecting column 64, the damping sleeve 65 and the spring 2 67. The connecting ring 66 pushes the bayonet 68, and the bayonet 68 is pushed and inserted into the slot 69. When the bayonet 68 is inserted into the slot 69, the bayonet 68 cooperates with the slot 69 to lock the right driving gear 58. At this time, when the motor 54, the transmission gear 55 and the driven gear 57 are driven When the movable shaft 56 rotates, since the right driving gear 58 is locked, the shaft 56 will squeeze the load pin 510 in the right driving gear 58 when it rotates, and the load pin 510 squeezes the spring 1 59, so that the right driving gear 58 and the shaft 56 are disconnected from each other. Therefore, the shaft 56 only drives the left driving gear 58 during the rotation process, so that the left bracket 52 pops out. By providing the locking device 6, the user can choose to eject the double detection position or the single detection position according to the use requirements, so that the user can place different gas collection cards for different detection positions and avoid the two detection positions from interfering with each other during the detection process. When the locking yoke 72 is in the state of being lifted up, the locking yoke 73 is in the state of being lifted up, and the locking yoke 73 is in the state of being lifted up, so that the user can lock the locking yoke 73 and lock the locking yoke 73 together. When the sample delivery device 5 is reset, the bracket 52 pulls the gas collecting card and the constraint shaft 72, and the constraint shaft 72 pulls the connecting frame 73. The connecting frame 73 moves with the bracket 52 and contacts the mounting frame 51 during the movement. At this time, the connecting frame 73 is pushed by the mounting frame 51 and drives the rubber block 74 to rotate under the guidance of the constraint shaft 72. The rubber block 74 gradually resets during the rotation. When the rubber block 74 is completely reset, the gas collecting card in the bracket 52 can be clamped. By setting the clamping device 7, the stability of the gas collecting card placed on the bracket 52 is improved, thereby avoiding the gas collecting card from offsetting during the detection process, resulting in errors in the detection data.

[0030] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device that performs control such as a computer.
