Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a novel artificial airway. Background Art

[0002] In hospital clinics, some patients need to use artificial airways to maintain basic breathing. Among them, the artificial airway is usually equipped with an air bag, which is inflated to expand the air bag, so that the air bag abuts against the inner wall of the patient's trachea. The setting of the air bag can not only fix the artificial airway on the patient's respiratory tract, but also prevent the oxygen of the artificial airway from leaking. Among them, the air bag is divided into two types: endotracheal intubation air bag and tracheotomy air bag. Whether it is an endotracheal intubation air bag or a tracheotomy air bag, since the air bag is fixed by abutting against the inner wall of the patient's trachea through expansion, the inner wall of the patient's trachea is compressed for a long time, which can easily cause ischemic damage or even necrosis of the tracheal mucosa. In severe cases, esophageal tracheal fistula may occur. In addition, the secretions or sputum produced by the patient's mouth are easy to flow into the patient's trachea. In order to avoid the long-term accumulation of these residues on the artificial airway air bag, the patient will suffer from respiratory tract infection. Medical staff are required to regularly clear the patient's trachea.

[0003] However, current artificial airway airbags are usually inflated and deflated manually, which is cumbersome and prone to misoperation, causing the stagnation in the trachea to flow into the patient's lungs. In addition, the sputum suction device provided externally is required to remove the stagnation, which is cumbersome.

[0004] Therefore, the above-mentioned technical defects need to be changed urgently. Utility Model Content

[0035] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0036] The utility model provides Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5Shown is a new type of artificial airway used to maintain or assist the patient's respiratory function. When the patient is unable to breathe on his own or his respiratory function is impaired, the doctor may take measures to intubate the artificial airway. Common artificial airways include endotracheal intubation and tracheotomy. Endotracheal intubation is the insertion of a tube into the patient's trachea to maintain patency and provide respiratory support. Tracheotomy is a surgical procedure that creates a tracheal incision in the neck, connects the trachea to the outside world, and then inserts an artificial airway tube. The use of an artificial airway can provide patients with oxygen supply, clear respiratory secretions, assisted ventilation, and other functions. The main structure of the novel artificial airway includes: an artificial airway 1 and an inflation and deflation device body 2. The artificial airway 1 includes a first end 11 and a second end 12 that are mutually connected. At least two air bags 13 are arranged axially spaced apart from each other on the outer wall of the artificial airway 1 near the second end 12. The air bags 13 are connected to a first conduit 14, and the first conduit 14 extends along the extension direction of the artificial airway 1. The inflation and deflation device body 2 is connected to an end of the first conduit 14 away from the air bag 13. The inflation and deflation device body 2 is used to inflate and deflate the air bag 13. When the air bag 13 is deflated, its volume is reduced, and the artificial airway 1 can move in the patient's trachea. When the air bag 13 is inflated, the volume of the air bag 13 increases until its outer wall abuts against the inner wall of the patient's trachea and reaches a certain pressure, so that the air bag 13 is fixed in the patient's trachea. It should be noted that the inflation pressure of the air bag 13 needs to reach a standard value to avoid excessive pressure that damages the patient's trachea.

[0037] The main body 2 of the inflation and deflation device is provided with a suction pump 21, the suction end of the suction pump 21 is connected to a second conduit 22, and the second conduit 22 extends to the position of the airbag 13. The suction pump 21 is used to suck the retained matter retained near the airbag 13 out of the patient's body.

[0038] It should be noted that the current artificial airway 1 airbag 13 is usually manually inflated and deflated, which is cumbersome to operate and prone to misoperation, resulting in the stagnation in the trachea flowing into the patient's lungs. In addition, the sputum suction device provided externally needs to be used to remove the stagnation, which is cumbersome to operate.

[0039] The present application solution periodically releases pressure from the airbag 13 through the main body 2 of the inflation and deflation device. By releasing pressure from the airbag 13, blood can circulate in the tracheal mucosal tissue compressed by the airbag 13, thereby preventing ischemic damage or even necrosis of the tracheal mucosa due to compression. The airbag 13 is then re-inflated to re-fix it. It should be noted that the present application solution is provided with more than two airbags 13 to fix the artificial airway 1. When the airbags 13 are deflated, the deflation processes of the two airbags 13 need to be staggered (i.e.: one airbag 13 is in the deflation stage, and the other airbag 13 needs to maintain sufficient air pressure) so that at least one airbag 13 fixes the artificial airway 1 in the patient's trachea.

[0040] The present application also uses a suction pump 21 to regularly remove the retained matter accumulated near the airbag 13. It should be noted that when the patient lies on the bed, his trachea is still tilted inward, so the retained matter will flow into the patient's lungs. In addition to having the function of fixing the artificial airway 1, the two airbags 13 in the present application can also prevent the retained matter from flowing into the patient's lungs. Before deflating the airbag 13, it is necessary to start the suction pump 21 to clean up the retained matter trapped on the side of the airbag 13. This prevents the patient from developing respiratory tract infections due to the long-term accumulation of retained matter.

[0041] Further, such as Figure 1 , Figure 2 , Figure 3 As shown, a suction end piece 23 is provided at one end of the second conduit 22 away from the suction pump 21, and the suction end piece 23 is provided with a suction port 231, and the suction port 231 is close to the outer side wall of the airbag 13. Specifically, the suction end piece 23 is arranged at the edge of the airbag 13 closest to the second end 12 of the artificial airway 1. In some embodiments, each airbag 13 is correspondingly provided with a suction end piece 23, that is, the airbag 13 and the suction end piece 23 are arranged in a one-to-one correspondence.

[0042] Further, such as Figure 2 , Figure 3 As shown, a connecting ring 232 is provided on one side of the suction end piece 23, and the connecting ring 232 is sleeved on the outer wall of the artificial airway 1, and the connecting ring 232 is movably connected to the outer wall of the artificial airway 1; specifically, the suction end piece 23 is movably connected to the artificial airway 1 through the connecting ring 232, and under the action of the gravity of the suction end piece 23 itself and the gravity of the second catheter 22, the suction end piece 23 will face downward.

[0043] The suction port 231 is arranged on the side of the suction end piece 23 away from the connecting ring 232. Since the suction end piece 23 faces downward, the suction port 231 also faces downward, so that the suction port 231 can remove the retentate more cleanly.

[0044] Further, such as Figure 3 As shown, the suction port 231 is in an arc-shaped structure. The arc-shaped structure has a smooth surface, which can prevent its outer surface from damaging the patient's tracheal inner wall mucosa.

[0045] Further, such as Figure 1 , Figure 2 As shown, the output end of the suction pump 21 is connected to a storage member 24, and the storage member 24 is detachably connected to the output end of the suction pump 21. The storage member 24 is used to store the retentate pumped out by the suction pump 21.

[0046] Furthermore, the main body 2 of the inflatable and deflation device includes: a shell 25, a battery 26, a control panel 27, and an inflatable and deflation device 28. A cavity is provided in the shell 25, and a display screen 251 and a plurality of buttons 252 are provided on the outside of the shell 25; the display screen 251 can display the pressure value of the airbag 13, and the working status of the suction pump 21 and other devices. The battery 26 is arranged in the cavity; in some other embodiments, an external power supply can be used to power the main body 2 of the inflatable and deflation device. The control panel 27 is arranged in the cavity; the inflatable and deflation device 28 is arranged in the cavity, and the inflatable and deflation device 28 is connected to the end of the first conduit 14 away from the airbag 13; wherein the battery 26, the display screen 251, the buttons 252, the inflatable and deflation device 28, and the suction pump 21 are all electrically connected to the control panel 27.

[0047] Furthermore, at least one of the inner wall of the first conduit and the inner wall of the airbag 13 is provided with a pressure sensor. The pressure sensor is used to sense the magnitude of the air pressure in the airbag 13.

[0048] Furthermore, a plurality of limiting rings 15 are provided on the side wall of the artificial airway 1 at positions corresponding to the airbag 13, and limiting rings 15 are provided at both ends of the axial direction of the airbag 13. The limiting rings 15 are used to limit the airbag 13 to prevent the airbag 13 from slipping off the artificial airway 1.

[0049] Furthermore, the airbag is cylindrical in structure, and an arc-shaped cutting edge 131 is arranged at the edge of the airbag, and the arc-shaped cutting edge 131 is arranged around the edge of the airbag, and a through hole 132 is opened in the middle of the airbag, and the airbag is sleeved on the artificial airway 1 through the through hole 132. It should be noted that the airbag is a sphere made of elastic material, and the inner diameter of the through hole 132 is smaller than the outer diameter of the artificial airway 1 under normal conditions, so that the airbag 13 can still be firmly sleeved on the artificial airway 1 regardless of the internal air pressure.

[0050] In summary, the present application provides a novel artificial airway 1, and the present application scheme uses the inflation and deflation device body 2 to regularly relieve pressure and inflate the airbag 13, and uses the suction pump 21 to regularly remove the retained matter accumulated near the airbag 13, thereby preventing the tracheal mucosa from being damaged by ischemia or even necrosis due to compression, and preventing the patient from developing respiratory tract infections due to the long-term accumulation of retained matter.

[0051] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
