Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a device for removing phlegm and crust from the inner wall of a trachea and a method for using the device. Background Art

[0002] In the process of clinical treatment, in order to ensure the patency of the respiratory tract of comatose long-term bedridden patients, endotracheal intubation is a common surgical operation to urgently relieve upper respiratory tract obstruction, absorb lower respiratory tract secretions, and establish a respiratory passage for patients. However, in actual operation, patients often encounter tracheal obstruction due to accumulation and scabbing of lower respiratory tract secretions. It is necessary to perform suction operations in time to suck out lower respiratory tract secretions to ensure the normal operation of the trachea. However, due to the insertion of the trachea, the water content of the lower respiratory tract secretions evaporates quickly, which easily forms thick sputum attached to the tracheal wall to form sputum scabs. Because most comatose patients have no spontaneous expectoration function, it is extremely difficult to cough up and clean up the sputum.

[0003] A Chinese invention patent with publication number CN117298364A discloses a respiratory sputum crust exploratory removal device. The present invention is provided with a rotating mechanism, so that the lower scraper block can rotate the rotating rod to rotate the lower scraper block during the process of removing sputum crust inside the trachea, thereby adjusting the suction angle and increasing the removal effect of the lower scraper block on the sputum crust. The present invention has the characteristics of strong practicality and facilitating the removal of sputum crust.

[0004] Currently, when scraping the sputum crust on the tracheal wall, since the sputum crust has less moisture and higher viscosity and the conjunctiva of the inner wall of the trachea is relatively fragile, it is easy to damage the conjunctiva of the inner wall of the trachea when using a scraper to scrape the sputum crust thereon, resulting in tracheal conjunctival infection.

[0016] The present invention also provides a method for using a tracheal endothelial wall sputum crust removal device, comprising the following steps:

[0017] Step S1: firstly, the capsule column is placed in the trachea of ​​the patient, and then high-pressure gas is supplied to the interior of the capsule column. The expansion of the airbag cover drives the expansion and scraping component to support and fix the capsule column between the inner walls of the trachea. At the same time, when the capsule column is pulled, the expansion and scraping component scrapes the sputum scab on the inner wall of the trachea. Before scraping, the sputum scab is softened by the atomization component, and the scraped sputum scab is removed by the sewage discharge component.

[0018] Step S2: When the expansion and scraping assembly is working, the airbag cover is inflated by filling high-pressure gas, and the airbag cover is clamped between the inner walls of the patient's trachea in an umbrella shape, and then the capsule column is pulled outward to fit the inner wall of the trachea through the open part of the airbag cover, so as to scrape off the sputum crust on the inner wall of the trachea;

[0019] Step S3: When the adjustment component is working, when the capsule column is placed inside the patient's trachea, the adjustment sleeve is in the initial position, and high-pressure gas is supplied to the inside thereof, and the gas flows to the expansion scraping component. When the expansion scraping component supports the device inside the patient's trachea, the adjustment sleeve needs to be pulled outward, and when pulling, the threaded connection between the threaded tube and the threaded ring drives the threaded ring to rotate, and then drives the turntable to rotate, so that the atomization component works to soften the sputum scab inside the trachea. After softening, the capsule column is pulled outward again, which can drive the capsule column to slide outward to remove the sputum scab, and at the same time, the sewage discharge component is opened to collect the scraped sputum scab;

[0020] Step S4: When the atomizing assembly is working, the rotating disk rotates, and the adjusting rod is driven to extend outward through the mutual constraint between the waist-shaped groove and the lever, so that the bending hole and the drainage hole are connected to each other, thereby sending the atomized gas into the space between the inner wall of the trachea and the outer surface of the capsule column;

[0021] Step S5: When the sewage discharge component is working, when the adjusting sleeve is pulled outward, the hexagonal plate will be driven to slide to one side, so that the opening and the guide hole are connected to each other. When the side port on the adjusting sleeve is connected to the first buffer cavity, the high-pressure gas can enter between the inside of the trachea and the outer surface of the capsule column, and the sputum crust scraped off on the inner side of the airbag cover is discharged into the inner cavity through the guide hole for collection.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention is provided with an expansion scraping component, an atomizing component, a sewage discharge component and an adjusting component, which is conducive to scraping the sputum scab inside the patient's trachea, preventing the tracheal mucosa from being damaged during scraping, and at the same time, the scraped sputum scab can be collected after scraping, preventing the sputum scab from falling into the trachea again when the device is taken out;

[0024] 2. The present invention can support the entire device and scrape the sputum crust at the same time by providing an expansion scraping assembly. When the expansion scraping assembly is working, the airbag cover is inflated by filling high-pressure gas, and is clamped between the inner walls of the patient's trachea in an umbrella shape. Then, when it is pulled outward, the airbag cover will fit the inner wall of the trachea through the open part of the airbag cover, thereby scraping the sputum crust on the inner wall of the trachea;

[0025] 3. The present invention can soften the sputum crust by providing an atomizing assembly, which is convenient for subsequent scraping. When the atomizing assembly is working, under the rotation of the turntable, the mutual constraint between the waist-shaped groove and the lever can drive the adjusting rod to extend outward, so that the bending hole and the drainage hole are connected to each other, thereby sending the atomized gas into the space between the inner wall of the trachea and the outer surface of the capsule column;

[0026] 4. The present invention can remove the scraped sputum crust in time by providing a sewage discharge component to prevent the sputum crust from falling again during the recovery device. When the sewage discharge component is working, when the adjusting sleeve is pulled toward the outside, the hexagonal plate will be driven to slide to one side, so that the opening and the guide hole are interconnected. When the side port on the adjusting sleeve is interconnected with the first buffer cavity, the high-pressure gas can enter between the inside of the trachea and the outer surface of the capsule column, and the sputum crust scraped off from the inner side of the airbag cover is discharged into the inner cavity through the guide hole for collection.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The expansion scraping assembly includes an airbag cover 2, which is fixed on the outer surface of the capsule column 1 near one end edge, and the side wall of the capsule column 1 near one end of the airbag cover 2 is provided with an air cavity 18, and the inner wall of the air cavity 18 is provided with a plurality of guide holes 21 that penetrate into the interior of the airbag cover 2 at equal intervals along the circumferential direction, and the inner wall of the other side of the inner cavity 19 is provided with an air inlet 20 that penetrates into the interior of the air cavity 18 in the middle.

[0037] The effect achieved is that, by providing an expansion scraping component, an atomization component, a sewage discharge component and an adjustment component, it is helpful to scrape the sputum crust inside the patient's trachea to prevent damage to the tracheal mucosa during scraping. At the same time, the scraped sputum crust can be collected after scraping to prevent the sputum crust from falling into the trachea again when the device is taken out. During use, the adjustment component can control the working order of the expansion scraping component, the atomization component and the sewage discharge component in sequence. When the expansion scraping component is working, the external high-pressure atomized gas enters the airbag cover 2, causing the airbag cover 2 to expand, thereby supporting the entire device. At the same time, when the device is subsequently pulled, the sputum crust is scraped off by fitting the open part of the airbag cover 2 with the inner wall of the trachea, and the air cavity 18 and the inside of the airbag cover 2 are connected through the guide hole 21, so that the high-pressure atomized gas can enter to expand the airbag cover 2.

[0038] like Figure 2 and Figure 4As shown, the adjustment component includes an adjustment sleeve 5, which is slidably arranged in the middle of the capsule column 1, a threaded tube 8 is fixed at one end of the adjustment sleeve 5, the threaded tube 8 is located inside the inner cavity 19, the other end of the adjustment sleeve 5 extends to the outside of the capsule column 1, an air supply hose 6 is fixed to the other end of the adjustment sleeve 5, an electromagnetic valve 11 is arranged between the inner walls of the threaded tube 8 away from the end of the adjustment sleeve 5, a plurality of air outlet holes 9 are equidistantly provided along the circumferential direction between the inner walls of the threaded tube 8 and close to the end of the adjustment sleeve 5, and a plurality of side openings 10 are equidistantly provided along the circumferential direction on the inner wall of the adjustment sleeve 5 and penetrate to the outside.

[0039] The effect achieved is that when the capsule column 1 is placed inside the patient's trachea, the adjusting sleeve 5 is in the initial position, and high-pressure gas is supplied to the inside thereof, and the gas will flow to the expansion scraping component. When the expansion scraping component supports the device inside the patient's trachea, it is necessary to pull the adjusting sleeve 5 toward the outside. When pulling, due to the threaded connection between the threaded tube 8 and the threaded ring 31, the threaded ring 31 will be driven to rotate and then the turntable 28 will be driven to rotate, so that the atomization component works to soften the sputum scab inside the trachea. After softening, pulling it toward the outside again can drive the capsule column 1 to slide toward the outside to remove the sputum scab, and at the same time, the sewage discharge component is opened to collect the scraped sputum scab, and a side port 10 is opened on the inner wall of the adjusting sleeve 5 to facilitate the introduction of airflow into the atomization component and the sewage discharge component.

[0040] like Figure 2 , Figure 3 and Figure 6 As shown, the atomization assembly includes a turntable 28, an annular groove 33 is provided on the inner wall of one side of the inner cavity 19, one side of the turntable 28 is slidably engaged in the inner part of the annular groove 33 near the edge of the outer surface, a plurality of waist-shaped grooves 29 are equidistantly provided on the outer surface of one side of the turntable 28 along the circumferential direction, a through hole 4 is provided on the inner bottom surface of the guide groove 3, one end of the through hole 4 penetrates to the outer surface of the adjusting sleeve 5, a limiting hole 34 is provided on the inner wall of one side of the through hole 4 and penetrates to the inner part of the inner cavity 19, an adjusting rod 26 is slidably connected to the inside of the through hole 4, a lever 30 is fixed on one side of the adjusting rod 26, the lever 30 slides inside the limiting hole 34, and one end of the lever 30 extends to the inner part of the waist-shaped groove 29 A plurality of connecting rods 32 are equidistantly fixed between the inner walls of the turntable 28, a threaded ring 31 is fixed between one ends of the plurality of connecting rods 32, the inner wall of the threaded ring 31 is threadedly connected to the outer surface of the threaded tube 8, a bending hole 27 is provided inside the adjusting rod 26, one end of the bending hole 27 penetrates to one end of the adjusting rod 26, and the other end of the bending hole 27 penetrates to the outer surface of the adjusting rod 26, a second buffer cavity 13 is provided inside the capsule column 1, the inner side of the second buffer cavity 13 is in contact with the outer surface of the adjusting sleeve 5, a plurality of drainage holes 14 are equidistantly provided on the inner wall of one side of the second buffer cavity 13 along the circumferential direction, and one end of the plurality of drainage holes 14 corresponds to the other end of the bending hole 27.

[0041] The effect achieved is that, in the process of pulling the adjusting sleeve 5 outward, the side port 10 on the adjusting sleeve 5 is communicated with the second buffer chamber 13. At the same time, under the rotation of the turntable 28, the mutual constraint between the waist-shaped groove 29 and the lever 30 can drive the adjusting rod 26 to extend outward, so that the bending hole 27 and the drainage hole 14 are communicated with each other. At this time, the atomized gas can be sent into the space between the inner wall of the trachea and the outer surface of the capsule column 1 through the bending hole 27 to soften the sputum scab on the inner wall of the trachea. The turntable 28 is engaged in the annular groove 33 to prevent shaking when the turntable 28 is rotated. At the same time, the lever 30 can be guided by sliding it in the limit port 34. The threaded ring 31 and the turntable 28 are connected by a connecting rod 32, so that the turntable 28 can be driven to rotate synchronously when the threaded ring 31 rotates.

[0042] like Figure 2 , Figure 3 and Figure 5 As shown, the sewage discharge assembly includes a hexagonal plate 16, and a plurality of through holes 17 are equidistantly provided on the outer surface of one side of the hexagonal plate 16. The hexagonal plate 16 is rotatably connected to the outer surface of the threaded tube 8 near one end edge. A hexagonal groove 15 is provided on the inner wall of the inner cavity 19. The hexagonal plate 16 is slidably engaged in the inside of the hexagonal groove 15. A plurality of guide grooves 3 are equidistantly provided on the outer surface of the capsule column 1 along the circumferential direction. A sewage discharge hole 22 penetrating into the inner cavity 19 is provided on the inner bottom surface of the plurality of guide grooves 3 near the inner wall of one side of the airbag cover 2.

A pull-out groove 23 inside the air cavity 18, multiple pull-out grooves 23 are slidably connected with soft nylon sheets 24 inside, one end of each soft nylon sheet 24 is fixed on the outer surface of one side of the hexagonal plate 16, multiple drainage holes 22 are correspondingly connected to the pull-out grooves 23, and the outer surfaces of multiple soft nylon sheets 24 are provided with openings 25 near one end of the air cavity 18. A first buffer cavity 12 is provided on the inner wall of the capsule column 1, and the inner side of the first buffer cavity 12 penetrates to the outer surface of the adjusting sleeve 5. The inner wall of the first buffer cavity 12 is provided with multiple through holes 7 that penetrate to the outside of the capsule column 1 at equal intervals along the circumferential direction.

[0043] The effect achieved is that the atomization component will be triggered before the sewage discharge component is triggered to work. When the atomization component is triggered, the air outlet hole 9 on the threaded tube 8 will slide to the inside of the threaded ring 31 and be closed by the threaded ring 31, so that the high-pressure atomized gas is no longer supplied to the expansion scraping component. The hexagonal plate 16 is slidably engaged in the inside of the hexagonal groove 15, which can be guided when it slides. The soft nylon sheet 24 is arranged in the inside of the pulling groove 23, which is convenient for pulling and controlling the opening and closing of the sewage discharge hole 22. When the adjusting sleeve 5 is pulled to the outside, the hexagonal plate 16 will be driven to slide to one side, so that the opening 25 and the guide hole 21 are connected to each other. When the side port 10 on the adjusting sleeve 5 is connected to the first buffer cavity 12, the high-pressure gas can enter between the inside of the trachea and the outer surface of the capsule column 1, and the sputum scab scraped off from the inner side of the airbag cover 2 is discharged into the inner cavity 19 through the guide hole 21 for collection. The through hole 17 is opened on one side of the hexagonal plate 16 to prevent the inner cavity 19 from being in a closed state.

[0044] The main problem solved by this embodiment is: using the regulating component to drive the atomizing component to soften the sputum scab on the inner wall of the patient's trachea, and at the same time driving the expanding scraping component to support the entire device between the inner walls of the patient's trachea, and scraping the softened sputum scab on the inner wall of the patient's trachea, and triggering the sewage discharge component to discharge and collect the scraped sputum scab, which solves the problem that the tracheal conjunctiva is easily damaged during the scraping of the sputum scab on the inner wall of the trachea, and also solves the problem that the scraped sputum scab is easy to fall into the inside of the trachea again when discharged, which is not convenient for the subsequent collection of the sputum scab. A method for using a tracheal inner wall sputum scab removal device includes the following steps:

[0046] Step S2: softening the sputum crust by the atomization component: in the process of pulling the adjusting sleeve 5 outward, the side port 10 on the adjusting sleeve 5 is communicated with the second buffer chamber 13, and at the same time, under the rotation of the turntable 28, the adjusting rod 26 is driven to extend outward through the mutual constraint of the waist-shaped groove 29 and the lever 30, so that the bending hole 27 and the drainage hole 14 are communicated with each other, and the atomized gas can be sent into between the inner wall of the trachea and the outer surface of the capsule column 1 through the bending hole 27 to soften the sputum crust on the inner wall of the trachea;

[0048] Step S4: Use the sewage discharge component to remove the scraped sputum crust: when the adjusting sleeve 5 is pulled outward, the hexagonal plate 16 will be driven to slide to one side, so that the opening 25 and the guide hole 21 are connected to each other. When the side port 10 on the adjusting sleeve 5 is connected to the first buffer cavity 12, the high-pressure gas can enter between the inside of the trachea and the outer surface of the capsule column 1, and the sputum crust scraped off on the inner side of the airbag cover 2 is discharged into the inner cavity 19 through the guide hole 21 for collection.
