A device for detecting intestinal diseases using methane and hydrogen breath

Abstract

The present invention relates to an intestinal disease detection device for methane and hydrogen breath applied in the field of medical equipment. The device utilizes a clamp rod and a collection bag to partially seal and cover the lips of a tester, so that when the tester leaks breath due to improper force or improper lip closure during subsequent breath sampling, the leaked gas can enter the collection bag, and the remaining exhaled gas in the collection bag is concentratedly transferred to the air inlet pipe through a smoothing mechanism or a micro motor, and then the air pump is started to suck and transfer the remaining gas in the transfer chamber and the air inlet pipe to the tester. Compared with the traditional straight-through breath test method, the detection device transfers the exhaled sample gas, and collects the leaked exhaled gas during the collection and transfer process, thereby ensuring that the exhaled gas can be fully transferred to the tester for gas content detection, which can effectively solve the problem of insufficient accuracy of the test results caused by gas leakage and residue.

Description

Technical Field

[0001] The present invention relates to an intestinal disease detection device for methane and hydrogen breath, and in particular to an intestinal disease detection device for methane and hydrogen breath applied in the field of medical equipment. Background Art

[0002] The hydrogen breath test is a simple medical test that measures the amount of hydrogen and methane in exhaled breath. It is used to help diagnose common digestive problems, including SIBO, irritable bowel syndrome, and lactose intolerance. The test results can help healthcare providers confirm or rule out certain specific causes of digestive problems. During the test, the tester needs to exhale for sampling.

[0003] The specification of Chinese invention patent CN202111553683.X discloses a human intestinal disease detection device for detecting methane and hydrogen breath, including a detection gas chamber, a chromatographic column, a filter bottle, a carrier gas pump, a first flow valve, a first flow meter, a drying tube, a metering ring, a second flow meter, a second flow valve, a sample gas pump, and first to third three-way solenoid valves; the human intestinal disease detection device has the advantages of high detectability, non-invasiveness, and convenience, and can be used for large-scale clinical and home patient data collection and diagnostic analysis.

[0004] Existing methane and hydrogen detection equipment often requires the tester to hold the air inlet end of the trachea in the mouth and then blow out to perform sampling operations when performing a breath test. However, in the actual sampling test operation, since the cross-sectional size of the trachea is smaller than the cross-sectional size of the lips when the tester holds the trachea in the mouth and blows out, and the tester has different abilities to close their upper and lower lips, the cross-sectional area of ​​the air outlet between the upper and lower lips in the closed state will expand until it crosses the trachea when blowing, causing the test gas to leak to the outside of the trachea. At the same time, the residual gas in the trachea after exhalation will not be transferred to the tester autonomously, further affecting the accuracy of the test results. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to prevent the exhaled test gas from leaking to the outside of the trachea during the methane hydrogen breath test, so as to ensure the accuracy of the test results.

[0006] In order to solve the above problems, the present invention provides an intestinal disease detection device for methane and hydrogen breath, comprising a tester, an air pump and a transfer chamber with a built-in disinfection lamp are installed on the surface of one side of the tester, a sealing hose is connected between the input end of the air pump and the air outlet end of the transfer chamber, and the output end of the air pump and the tester, and a solenoid valve is installed on the surface of the sealing hose, a through hole is provided at the air inlet end of the transfer chamber, a one-way valve is installed inside the through hole, and an air inlet pipe is detachably sealed inside the through hole, and a hoop is slidably sleeved on the surface of the air inlet pipe near the tail end, and the surface of the hoop is The surface is connected with symmetrically arranged adhesive arc blocks and movable grooves, and the adhesive arc blocks are made of self-adhesive adhesives, and the surface of the adhesive arc blocks is detachably bonded with a collection bag, and the inner wall of the collection bag close to the tail end of the air inlet pipe is coated with a medical adhesive layer, and one side of the medical adhesive layer is bonded with a release sticker, the interior of the movable groove is slidably connected with a clamping rod, and the collection bag is located inside the clamping rod, and the surface of the air inlet pipe is provided with an air hole with a built-in check valve and a gas flow meter, and the interior of the air hole is detachably connected with a branch pipe that is integrally sealed with the collection bag, and the diameter of the branch pipe is less than one fifth of the diameter of the air inlet pipe;

[0007] The clamping rod is composed of two round rods containing electromagnetic strips and a bent part, and the two electromagnetic strips attract each other. The surfaces of the two round rods approaching each other are flat, and the two ends of the bent part are respectively connected to the two round rods, and the bent part is located on the outside of the collection bag.

[0008] In the above-mentioned intestinal disease detection device for methane and hydrogen exhalation, a clamp rod and a collection bag are used to ensure that all exhaled gases are transferred to the tester for gas content detection, which can effectively solve the problem of insufficient test result accuracy caused by gas leakage and residue.

[0009] As a further improvement of the present application, a smoothing mechanism is installed inside the movable groove, and the smoothing mechanism includes a compression spring and an electromagnetic block, wherein the end of one round rod is slidably connected to the inner wall of the movable groove, the compression spring is installed on the inner wall of the movable groove on one side close to the bonding arc block, and one end of the compression spring is connected to the end of one of the round rods, the electromagnetic block is installed on the inner wall on the other side of the movable groove, and the electromagnetic block and the electromagnetic bar inside one of the round rods attract each other.

[0010] As a further improvement of the present application, a sampling feedback system is also included, which includes a controller, to which a supplement module, a warning module and an operation module are connected, the supplement module is connected to the two electromagnetic strips and the electromagnetic block signal, the warning module is connected to the gas flow meter signal, and the operation module is connected to the solenoid valve and the air pump signal.

[0011] As a further improvement of the present application, the length of the other round rod is smaller than the length of one of the round rods, and the bending portion is made of memory rubber, and the attraction force between the electromagnetic strips in the two round rods is greater than the elastic force of the bending portion.

[0012] As a further improvement of the present application, a surface of the air intake pipe near the rear end is provided with symmetrically arranged protrusions, and a distance between two protrusions facing away from one end of the air intake pipe is greater than a diameter of the hoop.

[0013] As a further improvement of the present application, the top wall and the bottom wall of the collection bag in the initial state are in a fitted and compressed state, and the collection bag and the branch pipe are both made of airtight disposable material.

[0014] As another improvement of the present application, the replacement structure of the smoothing mechanism is a micro motor, the micro motor is installed inside the movable groove, and the output end of the micro motor is connected to the end of one of the round rods.

[0015] As another improvement of the present application, a cleaning mechanism is installed on the inner wall of the tail end of the intake pipe, and the cleaning mechanism includes a magnetic block whose outer wall is coated with a magnetic coating and a cleaning ring sleeved on the outside of the magnetic block, and the outer surface of the cleaning ring is in contact with the inner wall of the intake pipe, and a magnetic ring that is attracted to the magnetic coating is slidably sleeved on the outer surface of the intake pipe, the magnetic ring has the same diameter as the hoop, and the magnetic ring is located on the side of the hoop away from the tail end of the intake pipe. In the initial state, there is a horizontal distance between the vertical projections of the magnetic block and the magnetic ring, and the horizontal distance does not exceed 5 cm.

[0016] As another improved supplement of the present application, an operating method of a device for detecting intestinal diseases using methane and hydrogen breath includes the following working steps:

[0017] S1. Before the test, one end of the newly opened storage bag needs to be glued to the surface of the adhesive arc block, and the storage bag needs to be overlapped on the surface of the round rod slidably connected to the moving groove, and the release sticker needs to be slowly torn off the surface of the medical adhesive layer. Then the tester needs to hold the tail end of the air intake pipe in his mouth and use the medical adhesive layer to stick the storage bag to the tester's face, covering part of the lips;

[0018] S2. The tester exhales, and the exhaled gas enters the transfer room through the air inlet pipe. At this time, the air pump and the solenoid valve are both in the closed state, and the exhaled test gas is transferred and stored;

[0019] S3. During the exhalation transfer process, if the exhaled gas of the tester leaks, it will enter the collection bag, causing the collection bag, which was originally in a compressed state, to gradually expand and transfer to the air inlet pipe in one direction through the branch pipe, and then enter the transfer room;

[0020] S4. After exhalation, the residual gas in the collection bag is in a relatively static state. At this time, the gas flow meter cannot detect the flow of fluid. The two electromagnetic strips are controlled by the supplementary module to start and seal the collection bag. Then the electromagnetic block is started to drive the clamping rod in the closed state to move horizontally, forcing the residual gas in the collection bag to transfer to the intake pipe. Then the collection bag is removed from the tester's face, and the collection bag and the branch pipe are removed from the surface of the intake pipe.

[0021] S5. After the gas transfer is completed, start the air pump and the solenoid valve to transport the remaining gas in the transfer room and the air inlet pipe to the tester for corresponding gas content detection to obtain the test results.

[0022] To summarize, by using the clamp rod and the collection bag, the lips of the tester can be partially sealed and covered when the tester is conducting a methane hydrogen test, so that when the tester is taking a subsequent breath sample and causing breath leakage due to improper force or improper lip closure, the leaked gas can enter the collection bag, and the exhaled gas remaining in the collection bag can be transferred to the air inlet pipe through a smoothing mechanism or a micro motor, and then the air pump is started to suck and transfer the residual gas in the transfer chamber and the air inlet pipe to the tester. Compared with the traditional straight-through breath test method, the present detection device transfers the exhaled sample gas and collects the leaked exhaled gas during the collection and transfer process, thereby ensuring that the exhaled gas can be fully transferred to the tester for gas content detection, which can effectively solve the problem of insufficient accuracy of test results caused by gas leakage and residue.

[0036] Three implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0037] The first implementation method:

[0038] Figure 1-5 A device for detecting intestinal diseases by methane and hydrogen breath is shown, comprising a tester 1, an air pump 2 and a transfer chamber 3 with a built-in disinfection lamp are installed on the surface of one side of the tester 1, a sealing hose is respectively connected between the input end of the air pump 2 and the air outlet end of the transfer chamber 3, and the output end of the air pump 2 and the tester 1, and a solenoid valve is installed on the surface of the sealing hose, a through hole is provided at the air inlet end of the transfer chamber 3, a one-way valve is installed inside the through hole, and an air inlet pipe 4 is detachably and sealedly connected inside the through hole, a hoop ring 6 is slidably sleeved on the surface of the air inlet pipe 4 near the tail end, a symmetrically arranged bonding arc block 61 and a movable groove 62 are connected to the surface of the hoop ring 6, and the bonding arc block 61 is made of self-adhesive, a collection bag 9 is detachably bonded to the surface of the bonding arc block 61, and an inner wall of one end of the collection bag 9 near the tail end of the air inlet pipe 4 is coated with a medical adhesive layer 10, and a release sticker 8 (such as Figure 7As shown in the figure, the interior of the movable groove 62 is slidably connected with a clamp rod 7, and the collection bag 9 is located inside the clamp rod 7, and the surface of the air inlet pipe 4 is provided with an air hole with a built-in check valve and a gas flow meter, and the interior of the air hole is detachably connected with a branch pipe 5 which is integrally sealed with the collection bag 9, and the diameter of the branch pipe 5 is less than one fifth of the diameter of the air inlet pipe 4;

[0039] The clamping rod 7 is composed of two round rods containing electromagnetic strips and a bent portion 71, and the two electromagnetic strips attract each other. The surfaces of the two round rods close to each other are flat. The two ends of the bent portion 71 are respectively connected to the two round rods, and the bent portion 71 is located on the outside of the collection bag 9.

[0040] Figure 6 It is shown that a smoothing mechanism is installed inside the movable groove 62, and the smoothing mechanism includes a compression spring 621 and an electromagnetic block 622, wherein the end of one round rod is slidably connected to the inner wall of the movable groove 62, the compression spring 621 is installed on the inner wall of one side of the movable groove 62 close to the bonding arc block 61, and one end of the compression spring 621 is connected to the end of one of the round rods, the electromagnetic block 622 is installed on the inner wall on the other side of the movable groove 62, and the electromagnetic block 622 and the electromagnetic bar in one of the round rods attract each other.

[0041] It also includes a sampling feedback system, which includes a controller, to which a supplement module, a warning module and an operation module are connected. The supplement module is connected to the two electromagnetic strips and the electromagnetic block 622 signals, the warning module is connected to the gas flow meter signals, and the operation module is connected to the electromagnetic valve and the air pump 2 signals.

[0042] Specifically, during the test, it is necessary to lay the collection bag 9 on the surface of the horizontally placed round rod in advance, and at the same time, seal and plug the end of the branch pipe 5 at the air hole. At this time, the collection bag 9 and the branch pipe 5 are in a horizontally stretched state. After that, the tester holds the tail end of the cleaned intake pipe 4 in the mouth, tears off the release sticker 8, and uses the medical adhesive layer 10 to attach the collection bag 9 to the lips of the face. The collection bag 9 covers the part of the lips that is not in contact with the intake pipe 4, so as to receive the gas leaked from this part later.

[0043] During the test, the tester exhales, causing the gas to enter the transfer chamber 3 through the air inlet pipe 4. If during this process, due to other problems such as the tester's lip closing ability, the exhaled gas partially leaks to the outside of the tail end of the air inlet pipe 4, it will enter the collection bag 9 (such as Figure 8As shown), the collection bag 9 which was originally in a compressed state can be gradually expanded, and transferred to the air inlet pipe 4 in one direction through the branch pipe 5, and a leakage prompt is issued to the outside through the warning module (because the air hole is connected with a gas flow meter and a check valve, when there is gas flow in the air hole, the gas flow meter can send a warning signal through the warning module. After the subsequent exhalation stops, due to the lack of subsequent gas supplementation, the gas in the air inlet pipe 4 and the collection bag 9 is in a static state. At this time, the gas flow meter fails to detect the gas flow, which can be used as a supplement module to start Signal), at this time, the supplementary module is started, and with the mutual attraction between the two electromagnetic strips, the end of the collection bag 9 can be clamped and sealed (because the clamping rod 7 is located at the end of the collection bag 9 in the initial state, it can form a sealing effect after closing), and then the electromagnetic block 622 is started, driving the round rod located in the moving groove 62 to move, and then driving the entire clamping rod 7 to move, squeezing the residual gas in the collection bag 9 to be transmitted to the intake pipe 4 (because the diameter of the branch pipe 5 is small and the length is effective, the influence of the residual gas on the overall test result is within the allowable error range, such as Fig. 9 shown);

[0044] When the gas transfer in the collection bag 9 is completed (i.e., the round rod moves to the position of the electromagnetic block 622), the collection bag 9 is removed from the face of the tester, and the tail end of the air inlet pipe 4 is sealed. Then, the air pump 2 and the electromagnetic valve are started to suck the gas in the transfer chamber 3 and the residual gas in the air inlet pipe 4 into the tester 1 for corresponding gas content detection, so that all the gas exhaled by the tester is sent to the tester 1 for testing to ensure the accuracy of the test results;

[0045] After the subsequent test is completed, the electromagnetic block 622 is turned off, and under the action of the compression spring 621, the clamping rod 7 is successfully restored to its original state.

[0046] The length of the other round rod is smaller than that of one of the round rods, and the curved portion 71 is made of memory rubber. The attraction force between the electromagnetic strips in the two round rods is greater than the elastic force of the curved portion 71 .

[0047] Specifically, during the adsorption and clamping, the adsorption effect between the electromagnetic strips can overcome the elastic effect of the curved portion 71, thereby achieving tight adsorption and ensuring the clamping and sealing effect of the storage bag 9.

[0048] The surface of the air inlet pipe 4 near the rear end is provided with symmetrically arranged protrusions, and the distance between the two protrusions facing away from one end of the air inlet pipe 4 is greater than the diameter of the hoop 6 .

[0049] Specifically, the raised arrangement facilitates the control of the position of the hoop 6 sleeved on the surface of the air intake pipe 4, thereby preventing the hoop 6 from being too far away from the rear end of the air intake pipe 4, thereby affecting the sealing effect of the subsequent collection bag 9 being attached to the face of the tester.

[0050] The top wall and the bottom wall of the storage bag 9 in the initial state are in a fitted and compressed state, and the storage bag 9 and the branch pipe 5 are both made of airtight disposable material.

[0051] Specifically, the disposable material can make the cost of the collection bag 9 and the branch pipe 5 within a controllable range. At the same time, the disposable material makes the collection bag 9 and the branch pipe 5 a replaceable structure, ensuring the safety of the test and avoiding the occurrence of cross-infection accidents.

[0052] An operating method of a device for detecting intestinal diseases using methane and hydrogen breath includes the following working steps:

[0053] S1. Before the test, one end of the newly opened storage bag 9 needs to be adhered to the surface of the adhesive arc block 61, and the storage bag 9 is overlapped on the surface of the round rod slidably connected to the movable groove 62, and the release sticker 8 is slowly torn off the surface of the medical adhesive layer 10. Then the tester holds the tail end of the air inlet pipe 4 in his mouth and, with the help of the medical adhesive layer 10, adheres the storage bag 9 to the tester's face, covering part of the lips;

[0054] S2, the test person exhales, and the exhaled gas enters the transfer chamber 3 through the air inlet pipe 4. At this time, the air pump 2 and the solenoid valve are both in the closed state, and the exhaled test gas is transferred and stored;

[0055] S3. During the exhalation transfer process, if the exhaled gas of the tester leaks, it will enter the collection bag 9, causing the collection bag 9, which was originally in a compressed state, to gradually expand and transfer to the air inlet pipe 4 through the branch pipe 5 in one direction, and then enter the transfer chamber 3;

[0056] S4. After exhalation, the residual gas in the collection bag 9 is in a relatively static state. At this time, the gas flow meter cannot detect the passage of fluid. The two electromagnetic strips are controlled by the supplementary module to start, and the collection bag 9 is sealed. Then, the electromagnetic block 622 is started to drive the clamping rod 7 in the closed state to move horizontally, forcing the residual gas in the collection bag 9 to transfer to the air inlet pipe 4. Then, the collection bag 9 is removed from the face of the tester, and the collection bag 9 and the branch pipe 5 are removed from the surface of the air inlet pipe 4.

[0057] S5. After the gas transfer is completed, the air pump 2 and the solenoid valve are started to transport the residual gas in the transfer chamber 3 and the air inlet pipe 4 to the tester 1 for corresponding gas content detection to obtain the test result.

[0058] The second implementation method:

[0059] Fig.10 The alternative structure of the smoothing mechanism is a micro motor, the micro motor is installed inside the movable groove 62, and the output end of the micro motor is connected to the end of one of the round rods.

[0060] Different from the first embodiment, this embodiment adopts a winding extrusion method to replace the translation extrusion method in the first embodiment, and replaces the electromagnetic block 622 and the compression spring 621 in the first embodiment with a micro motor.

[0061] Specifically, when performing extrusion exhaust, it is necessary to start the micro motor after the two electromagnetic strips adsorb and tightly clamp the collection bag 9, which can drive the two round rods in the clamping and adsorption state to rotate, thereby driving the collection bag 9 clamped therein to be rolled up and extruded, thereby completing the corresponding extrusion exhaust operation.

[0062] The third implementation method:

[0063] Fig.11 It is shown that a cleaning mechanism is installed on the inner wall of the tail end of the intake pipe 4, and the cleaning mechanism includes a magnetic block 11 whose outer wall is coated with a magnetic coating and a cleaning ring 12 sleeved on the outside of the magnetic block 11, and the outer surface of the cleaning ring 12 fits the inner wall of the intake pipe 4, and the outer surface of the intake pipe 4 is slidably sleeved with a magnetic ring 13 that attracts the magnetic coating, and the magnetic ring 13 has the same diameter as the hoop 6, and the magnetic ring 13 is located on the side of the hoop 6 away from the tail end of the intake pipe 4. In the initial state, there is a horizontal distance between the vertical projections of the magnetic block 11 and the magnetic ring 13, and the horizontal distance does not exceed 5 cm.

[0064] Different from the first and second embodiments, this embodiment adds a cleaning mechanism to assist in the cleaning operation of the inner wall of the intake pipe 4 after a single test, so as to avoid the accuracy of the test results being affected by residues during the two rounds of testing, and the surface of the cleaning ring 12 is covered with a non-woven fabric cover soaked in disinfectant.

[0065] After the test is completed, the air intake pipe 4 is first removed from the surface of the transfer chamber 3, and then the collection bag 9 is removed. The magnetic block 11 is pushed toward the direction of the magnetic ring 13 with a finger covered with a disinfectant tablet, driving the cleaning ring 12 to move from the tail end of the air intake pipe 4 and clean the inner wall of the air intake pipe 4 until the cleaning ring 12 moves to the position of the magnetic ring 13. Then, the magnetic ring 13 is moved, and the magnetic attraction between the magnetic ring 13 and the magnetic coating drives the cleaning ring 12 to scrape and clean the inner wall of the air intake pipe 4 until the cleaning ring 12 is discharged from the other end of the air intake pipe 4. The cleaning is completed, and the transfer chamber 3 is sterilized and cleaned using a disinfection lamp. This can reduce the interference of the residue on the inner wall of the air intake pipe 4 on the test results during the two rounds of detection operations, thereby further improving the accuracy of the test results.

[0066] In summary, the detection device utilizes the clamp rod 7 and the collection bag 9 to partially seal and cover the lips of the tester when the tester is conducting a methane hydrogen test, so that when the tester is taking a subsequent breath sample and causing breath leakage due to improper force or improper lip closure of the tester, the leaked gas can enter the collection bag 9, and the exhaled gas remaining in the collection bag 9 is concentratedly transferred to the air inlet pipe 4 through a smoothing mechanism or a micro motor, and then the air pump 2 is started to suck and transfer the residual gas in the transfer chamber 3 and the air inlet pipe 4 to the tester 1. Compared with the traditional straight-through breath test method, the detection device transfers the exhaled sample gas, and collects the leaked exhaled gas during the collection and transfer process, thereby ensuring that the exhaled gas can be fully transferred to the tester 1 for gas content detection, which can effectively solve the problem of insufficient accuracy of the test results caused by gas leakage and residue.

[0067] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.

Before the test, one end of the newly opened collection bag (9) needs to be adhered to the surface of the adhesive arc block (61), and the collection bag (9) needs to be overlapped on the surface of the round rod slidably connected to the movable groove (62), and the release sticker (8) needs to be slowly torn off the surface of the medical adhesive layer (10). Then, the tester holds the tail end of the air inlet tube (4) in his mouth and, with the help of the medical adhesive layer (10), adheres the collection bag (9) to the face of the tester, covering part of the lips; S2, the test person exhales, and the exhaled gas enters the transfer chamber (3) through the air inlet pipe (4). At this time, the air pump (2) and the solenoid valve are both in a closed state, and the exhaled test gas is transferred and stored; S3. During the exhalation transfer process, if the exhaled gas of the test person leaks, it will enter the collection bag (9), causing the collection bag (9) that was originally in a compressed state to gradually expand and transfer unidirectionally through the branch pipe (5) to the air inlet pipe (4), and then enter the transfer chamber (3); S4. After exhalation is completed, the residual gas in the collection bag (9) is in a relatively static state. At this time, the gas flow meter cannot detect the passage of fluid. The two electromagnetic strips are controlled by the supplementary module to start, and the collection bag (9) is sealed. Then, the electromagnetic block (622) is started to drive the clamping rod (7) in the closed state to move horizontally, forcing the residual gas in the collection bag (9) to transfer to the air intake pipe (4). Then, the collection bag (9) is removed from the face of the test person, and the collection bag (9) and the branch pipe (5) are removed from the surface of the air intake pipe (4); S5. After the gas transfer is completed, the gas pump (2) and the solenoid valve are started to transport the residual gas in the transfer chamber (3) and the air inlet pipe (4) to the tester (1) for corresponding gas content detection to obtain the test results.
