Description

Technical Field

[0001] The present invention relates to the technical field of airway patency devices, and in particular to an airway patency device for clinical use in geriatric medicine. Background Art

[0002] An airway patency device is a device used in respiratory support. Its main function is to promptly remove foreign objects inside the patient's airway, prevent airway obstruction, and keep the airway open, which is conducive to ensuring that airflow can smoothly enter and exit the lungs, improve ventilation efficiency, and provide conditions for effective respiratory support.

[0003] When using an airway patency device to deal with foreign objects in the trachea, a tube needs to be sent into the place where the foreign object is in the trachea, and the foreign object is extracted using the principle of negative pressure. However, if the foreign object in the trachea is vomit, blood clots, pus, or other foreign objects that enter the airway and contain inclusions or high viscosity, during the extraction process, if too little pressure is used, some inclusions will be stuck in the tube, affecting the removal of the foreign object and greatly increasing the occurrence of friction damage to the airway mucosa. Once the pressure is increased, at the moment the foreign object passes through the tube, the pressure at the end of the tube that absorbs the foreign object in the airway will instantly increase. At this time, part of the airway mucosa will be sucked into the side hole or end hole of the tube, causing tearing or bleeding. Bleeding greatly increases the possibility of airway blockage, aggravating breathing difficulties, and even causing aspiration.

[0004] Especially when the patient is an elderly person, who has more physiological decline and comorbidities, is more likely to suffer from new airway damage. To avoid this, the tube is generally inserted near the foreign body, negative pressure is started and slowly withdrawn to avoid fixed-point suction. At the same time, the tube is slightly rotated to change the direction of the tube mouth to prevent continuous adsorption of the mucosa in the same area, thereby avoiding the impact of pressure fluctuations on the patient's airway. However, the airway mucosa of the elderly may still be slightly damaged due to repeated friction or short-term negative pressure fluctuations, leading to bleeding or edema, inducing chronic airway inflammation, and accelerating mucosal fibrosis, which is still difficult to reduce the damage to the patient's airway. Summary of the Invention

[0005] The present invention proposes an airway patency device for clinical use in geriatric medicine, which is used to solve the problem in the prior art that when vomitus, blood clots, pus and other foreign objects with inclusions or high viscosity enter the airway during extraction, the instantaneous pressure at the end of the tube that absorbs the foreign object increases at the moment the foreign object passes through the tube, thereby aggravating the damage to the airway mucosa.

[0010] On the basis of the above solution, the sliding voltage regulating unit includes: Slide rails, two of which are symmetrically and fixedly installed inside the handle, and the two slide rails correspond to the two protective plates respectively; A sliding frame, wherein the sliding frame is slidably mounted between the two slide rails and the sliding frame is slidably engaged with the protective plate; An arc-shaped pressure regulating block is fixedly mounted on the sliding frame, and a plurality of anti-slip grooves are provided at the position where the arc-shaped pressure regulating block contacts the vent pipe; A driving member is installed on the handle and is used to push the sliding frame to move.

[0011] On the basis of the above solution, the driving member includes: A driving frame, the driving frame is fixedly mounted on the handle; Gears, two gears are symmetrically and rotatably mounted inside the driving frame; A roller, the driving frame is rotatably mounted with the roller, the two gears are respectively located on both sides of the roller, and the two gears are respectively coaxial with the roller and fixedly connected; Racks, two racks are symmetrically and fixedly mounted on the sliding frame, and the racks are engaged with the gears.

[0012] On the basis of the above scheme, in order to deal with foreign objects in the trachea, a hose is also included. The hose is detachably connected to the input end of the suction pipe and can be installed to the suction pipe when needed. The hose is made of soft materials such as silicone.

[0013] On the basis of the above solution, in order to prevent foreign matter in the collection tank from being sucked into the air bag and contaminating the air bag, or entering the air extraction pipe, the method further includes: A splash-proof tube, the splash-proof tube being arranged on a stepped table inside the collection tank, with a gap being left between the outer wall of the splash-proof tube and the inner wall of the collection tank; A collecting bag is arranged inside the collecting tank, and an edge of the opening of the collecting bag is located between the splash-proof tube and the collecting tank.

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments 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 making any creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 8 As shown, this embodiment proposes an airway patency device for clinical use in geriatric medicine, including a collecting tank 1, a collecting cover 2 is detachably installed on the top of the collecting tank 1, an exhaust pipe 3 and an inhalation pipe 4 are fixedly installed on the top of the collecting cover 2, and also includes a mounting frame 5, a negative pressure stabilizing component, a handle 6, a pressure gauge 7 and a negative pressure regulating component. Several mounting frames 5 are fixedly installed on the top of the collecting cover 2, and a negative pressure stabilizing component is installed inside each mounting frame 5 for passively adjusting the pressure fluctuations generated when handling viscous foreign matter. The negative pressure stabilizing component includes an airbag 8 and an isolation net 9. The airbag 8 can be detachably installed on several mounting frames 5. The opening position of the airbag 8 is connected to the outside world, the wall thickness of each airbag 8 is different, and an isolation net 9 is fixedly installed at the opening position of each airbag 8.

[0023] Specifically, before use, the operator first installs the collection tank 1 on the lower part of the collection cover 2, and connects the hose 21 to the suction tube 4, then holds the handle 6, moves the device to the patient's oral position, opens the patient's mouth, and sends the hose 21 to the position of the foreign body blocking the patient's airway (the foreign body may be sputum, or it may be a blood clot, or vomit entering the airway, hereinafter referred to as foreign body), then starts the negative pressure regulating component, and extracts negative pressure through the suction tube 3, so that the foreign body in the patient's airway is sucked out into the collection tank 1 through the cooperation of the suction tube 4 and the hose 21. During the collection process, the operator always pays attention to the reading of the pressure gauge 7, and then adjusts the negative pressure according to the actual situation, especially when the patient is an elderly person, due to the physiological decline and comorbidities of the elderly. The airway mucosa is more fragile and needs to be operated with caution to avoid airway damage due to excessive negative pressure. When dealing with some foreign objects with inclusions such as vomitus and blood clots that enter the airway, when the foreign object partially blocks the suction tube, the suction force will accumulate in the hose 21 and the suction tube 4. At this time, the negative pressure at the tube mouth temporarily increases, but when the foreign object is suddenly sucked out, the negative pressure at the tube mouth will instantly act on the exposed airway wall. If the mucosa is fragile, it may be sucked into the tube 4 mouth and tear. At this time, through the setting of the airbag 8, when internal pressure fluctuations occur, the airbag 8 can expand rapidly to buffer the negative pressure impact, thereby protecting the airway mucosa from damage. Through the setting of the isolation net 9, some external impurities can be prevented from entering the airbag 8 and affecting the service life of the airbag 8.

[0024] It should be added that, since the pressure required for different situations (such as suctioning sputum, vomit, blood clots or pus) is not consistent, the design of several air bags 8 with different wall thicknesses can cover most situations to adapt to different degrees of negative pressure requirements, ensuring that pressure fluctuations can be effectively buffered in various situations, thereby maximizing the protection of the patient's airway safety and ensuring the smooth progress of the medical process.

[0025] like Figures 2 to 7 As shown, the handle 6 is fixedly mounted on the side of the collecting cover 2, the pressure gauge 7 is fixedly mounted on the handle 6, one end of the pressure gauge 7 is connected to the exhaust pipe 3, the negative pressure regulating component is mounted inside the handle 6, for extracting foreign matter and controlling the negative pressure level in the suction pipe 4, the negative pressure regulating component includes an air pump 10, a vent pipe 11, a mounting portion and a sliding pressure regulating portion, the air pump 10 is fixedly mounted inside the handle 6, the vent pipe 11 is connected between the input end of the air pump 10 and the other end of the pressure gauge 7, the mounting portion is mounted inside the handle 6, for fixing the position of the vent pipe 11, the sliding pressure regulating portion is mounted on the handle 6, for adjusting the gas flow passing through the vent pipe 11.

[0026] Specifically, when dealing with foreign objects in the patient's airway, the air pump 10 is started, and the air pump 10 draws negative pressure through the ventilation tube 11 and the exhaust tube 3. Under the action of the mounting part, the negative pressure is adjusted by the sliding pressure regulating part to ensure that the negative pressure meets the relevant requirements. In addition, during the operation, the negative pressure can be slightly adjusted according to the patient's condition or the type of foreign object, thereby achieving precise control, ensuring effective operation while improving the safety and comfort of the patient.

[0027] The above, such as Figure 3 、 Figure 4 As shown, the mounting portion includes an assembly frame 12 and a protective plate 13. The assembly frame 12 is fixedly installed inside the handle 6. The side of the assembly frame 12 that contacts the ventilation pipe 11 is set as an inclined surface. The assembly frame 12 abuts against the ventilation pipe 11. Protective plates 13 are fixedly installed on both sides of the assembly frame 12. The two protective plates 13 are symmetrically arranged, and there is a gap between the protective plates 13 and the ventilation pipe 11.

[0028] Specifically, since the side of the assembly frame 12 that contacts the vent pipe 11 is set as an inclined surface, the end of the inclined surface close to the pressure gauge 7 is higher than the other end, so that the vent pipe 11 can rely on this inclined surface to press the vent pipe 11 under the action of the sliding pressure regulating part, thereby changing the cross-sectional area of ​​the vent pipe 11, and then adjusting the size of the negative pressure to ensure precise operation. The protective plate 13 effectively prevents the vent pipe 11 from deviating from the track when sliding, ensures the stability of the adjustment process, and further improves the safety and reliability of the equipment.

[0029] The above, such as Figures 5 to 7As shown, the sliding pressure regulating part includes a slide rail 14, a slide frame 15, an arc-shaped pressure regulating block 16 and a driving component. Two slide rails 14 are symmetrically and fixedly installed inside the handle 6. The two slide rails 14 correspond to the two protective plates 13 one by one. The slide frame 15 is slidably installed between the two slide rails 14. The slide frame 15 slides with the protective plate 13. An arc-shaped pressure regulating block 16 is fixedly installed on the slide frame 15. The position where the arc-shaped pressure regulating block 16 contacts the ventilation pipe 11 is provided with multiple anti-slip grooves. The driving component is installed on the handle 6 to push the slide frame 15 to move.

[0030] Specifically, when adjusting the negative pressure, the driving component is manually adjusted so that the sliding frame 15 moves on the slide rail 14, and the sliding frame 15 cooperates with the protective plate 13 to ensure the smoothness of the sliding. As the sliding frame 15 moves, the arc-shaped pressure regulating block 16 is driven to move along the slide rail 14. Due to the action of the inclined surface of the assembly frame 12, the distance between the arc-shaped pressure regulating block 16 and the ventilation pipe 11 is different at different positions, thereby compressing the ventilation pipe 11, changing its cross-sectional area, and realizing precise adjustment of the negative pressure.

[0031] Due to the presence of the anti-slip grooves, through the cooperation of the anti-slip grooves and the vent pipe 11, the position can be automatically fixed after the negative pressure is adjusted, which is convenient for one-handed operation.

[0032] To further supplement the negative pressure requirements, when aspirating sputum, the suction force is generally adjusted to 80-120 mmHg; when aspirating blood clots, the suction force is generally adjusted to less than or equal to 100 mmHg; when aspirating vomitus, the suction force is generally adjusted to 100-150 mmHg; when aspirating pus, the suction force is generally adjusted to 120-150 mmHg. However, the minimum suction force that has a suction effect is generally used within the range, and the above only lists some examples. The specific operation needs to be judged by professional medical staff based on actual conditions.

[0033] The above, such as Figure 7 As shown, the driving component includes a driving frame 17, a gear 18, a roller 19 and a rack 20. The driving frame 17 is fixedly mounted on the handle 6. Two gears 18 are symmetrically and rotatably mounted inside the driving frame 17. A roller 19 is rotatably mounted on the driving frame 17. The two gears 18 are respectively located on both sides of the roller 19. The two gears 18 are respectively coaxial with the roller 19 and fixedly connected. Two racks 20 are symmetrically and fixedly mounted on the sliding frame 15, and the racks 20 are engaged with the gears 18.

[0034] Specifically, when adjusting the negative pressure, the roller 19 is manually rotated, and the roller 19 drives the gear 18 to rotate in the same direction, and the gear 18 drives the rack 20 to move, thereby driving the sliding frame 15 to move smoothly along the slide rail 14, thereby adjusting the negative pressure.

[0035] The above, such as Figure 1 As shown, in order to handle foreign matter in the trachea, a hose 21 is also included. The hose 21 is detachably connected to the input end of the suction pipe 4 and can be installed on the suction pipe 4 when needed. The hose 21 is made of a soft material, such as silicone, and is also equipped with an anti-bite block 24. Specifically, the hose 21 is preferably designed as a disposable hose 21, which can be discarded after use to avoid cross contamination. The length of the hose 21 can be selected according to the patient's condition. The hose 21 is soft and easy to bend, and the end of the hose 21 that contacts foreign objects needs to avoid sharp corners to avoid damaging the airway. In order to prevent the patient from biting the hose 21 and causing the ventilation tube 11 to be blocked, an anti-bite block 24 is provided on the hose 21. The anti-bite block 24 is set to be cylindrical. The part of the anti-bite block 24 that contacts the hose 21 is made of a harder material, such as metal or hard plastic, to avoid the hose 21 being bitten or blocked. The outside of the anti-bite block 24 is made of flexible materials, such as rubber, to ensure the comfort of the patient.

[0036] The above, such as Figure 8 As shown, in order to prevent foreign matter from being sucked into the collection tank 1 and contaminating the airbag 8 or entering the exhaust pipe 3, a splash-proof tube 22 and a collection bag 23 are also included. The splash-proof tube 22 is arranged on the stepped table inside the collection tank 1. There is a gap between the outer wall of the splash-proof tube 22 and the inner wall of the collection tank 1. The bottom of the splash-proof tube 22 is arranged as a mesh structure. The output end of the suction pipe 4 is located at the bottom of the splash-proof tube 22. A through hole for passing the suction pipe 4 is also provided at the bottom of the splash-proof tube 22. The collection bag 23 is arranged inside the collection tank 1, and the edge of the opening of the collection bag 23 is located between the splash-proof tube 22 and the collection tank 1.

[0037] Specifically, when installing the collection tank 1, first place the collection bag 23 into the collection tank 1, with the bag mouth of the collection bag 23 inside the collection tank 1, and then place the splash-proof tube 22 into the collection tank 1, with the splash-proof tube 22 against the stepped table inside the collection tank 1, and the bag mouth of the collection bag 23 is located in the gap between the splash-proof tube 22 and the inner wall of the collection tank 1, and then align the through hole at the bottom of the splash-proof tube 22 with the suction pipe 4, insert the suction pipe 4 into the through hole and install the collection tank 1 on the lower part of the collection cover 2 preferably by means of a threaded connection. When dealing with foreign matter in the patient's airway, the splash-proof tube 22 can effectively prevent foreign matter from splashing into the exhaust pipe 3 or contaminating the airbag 8, and the collection bag 23 collects foreign matter in a centralized manner for easy cleaning and sampling.

[0038] The working principle or usage process of this application is as follows: Before use, the operator first places the collection bag 23 into the collection tank 1, with the bag mouth of the collection bag 23 inside the collection tank 1, and then places the splash guard 22 into the collection tank 1, with the splash guard 22 against the stepped table inside the collection tank 1, and the bag mouth of the collection bag 23 is located in the gap between the splash guard 22 and the inner wall of the collection tank 1, then aligns the through hole at the bottom of the splash guard 22 with the suction pipe 4, inserts the suction pipe 4 into the through hole and installs the collection tank 1 at the lower part of the collection cover 2, and then connects the hose 21 to the suction pipe 4. In order to prevent the patient from biting the hose 21 and causing the ventilation tube 11 to be blocked, an anti-bite block 24 is provided on the hose 21. The anti-bite block 24 is set to be cylindrical, and the part of the anti-bite block 24 that contacts the hose 21 is made of a harder material, such as metal or hard plastic, to prevent the hose 21 from being bitten or blocked. The outside of the anti-bite block 24 is made of flexible materials, such as rubber, to ensure the comfort of the patient.

[0039] When in use, hold the handle 6, move the device to the patient's oral position, open the patient's oral cavity, and send the hose 21 into the position where the foreign body is blocking the patient's airway. Then start the air pump 10, and the air pump 10 draws negative pressure through the ventilation tube 11 and the exhaust pipe 3. Since the side of the assembly frame 12 that contacts the ventilation tube 11 is set as an inclined surface, the end of the inclined surface close to the pressure gauge 7 is higher than the other end, so that the ventilation tube 11 can rely on this inclined surface to press the ventilation tube 11 under the action of the arc-shaped pressure regulating block 16, thereby changing the cross-sectional area of ​​the ventilation tube 11 and further adjusting the negative pressure. During the adjustment process, by manually rotating the roller 19, the roller 19 can drive the gear 18 to rotate in the same direction, and the gear 18 drives the rack 20 to move, thereby driving the sliding frame 15 to move smoothly along the slide rail 14. As the sliding frame 15 moves, the arc-shaped pressure regulating block 16 is driven to move along the slide rail 14. Since the arc-shaped pressure regulating block 16 is affected by the inclined surface of the assembly frame 12, the distance between the arc-shaped pressure regulating block 16 and the ventilation pipe 11 is different at different positions, thereby compressing the ventilation pipe 11, changing its cross-sectional area, and realizing precise adjustment of the negative pressure. This process can be operated with one hand, which improves convenience.

[0040] During the collection process, the operator always pays attention to the reading of the pressure gauge 7, and then adjusts the negative pressure according to the actual situation, especially when the patient is an elderly person. Due to the physiological decline and more comorbidities of the elderly, their airway mucosa is weaker, and more careful operation is required to avoid airway damage due to excessive negative pressure. When dealing with some foreign objects with inclusions such as vomitus and blood clots that enter the airway, when the foreign object partially blocks the suction tube, the suction force will accumulate in the hose 21 and the suction tube 4. At this time, the negative pressure at the tube mouth temporarily increases, but when the foreign object is suddenly sucked out, the negative pressure at the tube mouth will instantly act on the exposed airway wall. If the mucosa is fragile, it may be sucked into the tube 4 mouth and tear. At this time, through the setting of the airbag 8, when internal pressure fluctuations occur, the airbag 8 can expand rapidly to buffer the negative pressure impact, thereby protecting the airway mucosa from damage. Through the setting of the isolation net 9, some external impurities can be prevented from entering the airbag 8 and affecting the service life of the airbag 8.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
