Technical Field
[0001] The present application relates to the technical field of oropharyngeal airways, and in particular to an oropharyngeal airway with a sputum suction function. Background Art
[0002] The oropharyngeal airway, also known as the oropharyngeal ventilator, is a non-tracheal tube non-invasive ventilation tube that can prevent the tongue from falling back, quickly open the airway, and establish a temporary artificial airway. The oropharyngeal airway is usually a disposable medical product made of rubber or plastic, and can also be made of metal or other elastic materials. The oropharyngeal airway commonly used in clinical practice is an elliptical hollow plastic tube.
[0003] Currently, sedatives and analgesics are generally used during general anesthesia for endotracheal intubation. It is inevitable that upper airway obstruction such as tongue root fall will occur. At this time, the anesthesiologist will lift the patient's lower jaw and open the airway to help the patient breathe. If the tongue root fall cannot be resolved for a long time, an oral airway will be inserted to help the patient breathe.
[0004] However, during actual use, because the patient is under general anesthesia and unconscious and cannot swallow independently, the secretions in the patient's mouth will gradually accumulate in the patient's mouth, and there may be a risk of reflux and aspiration of the secretions. For this reason, the present application provides an oropharyngeal airway with a suction function. Utility Model Content

[0028] The following is combined with Figure 1-4 This application is described in further detail.
[0029] The embodiment of the present application discloses an oropharyngeal airway with sputum suction function.
[0030] Reference Figure 1 , Figure 2 and Figure 4An oropharyngeal airway with sputum suction function comprises a pharyngeal bending tube 1, a flange opening 2 is fixedly connected to the top of the pharyngeal bending tube 1, a sputum suction component 3 is installed inside the pharyngeal bending tube 1, a miniature camera 4 is installed inside the pharyngeal bending tube 1, and the miniature camera 4 is electrically connected to an external controller. Grooves 5 are provided at both ends of the flange opening 2, a fixing component 6 is installed inside the groove 5, a soft silicone dental pad 7 is sleeved on the pharyngeal bending tube 1, and two soft pads 8 are symmetrically fixedly connected to the soft silicone dental pad 7.
[0031] When using the device, first, the patient is laid flat on the bed, and then the pharyngeal flexure tube 1 is inserted into the patient's mouth, and the insertion is stopped after the patient's teeth reach between the two soft pads 8. The soft silicone tooth pad 7 can improve the protection of the patient's teeth, and the two soft pads 8 can limit the patient's teeth to ensure that the occlusal part is not easy to loosen and prevent the pharyngeal flexure tube 1 from sliding in the patient's mouth. The device is then fixed by the fixing component 6 to prevent the device from falling off the patient's mouth. During use, the situation in the patient's mouth is monitored in real time by the micro camera 4. When a lot of secretions are observed in the mouth, the secretions in the mouth are suctioned and cleaned by operating the sputum suction component 3, thereby reducing the risk of reflux and aspiration of secretions, effectively improving the practicality of the device.
[0032] Reference Figure 1 and Figure 2 The sputum suction component 3 includes a sputum suction tube 31 slidably arranged inside the pharyngeal curved tube 1, one end of the sputum suction tube 31 is hinged with a connecting tube 32, a plurality of support columns 33 are evenly and fixedly connected to the inner wall of the pharyngeal curved tube 1, the sputum suction tube 31 is slidably arranged inside the support column 33, the connecting tube 32 is slidably arranged inside the support column 33, an air bag 34 is fixedly connected to the inner wall of the pharyngeal curved tube 1, the air bag 34 is located at the bottom of the hinge between the sputum suction tube 31 and the connecting tube 32, one end of the air bag 34 is fixedly connected to an air supply tube 35, an end of the air supply tube 35 away from the air bag 34 is fixedly connected to an extrusion balloon 36, and a valve 37 is fixedly connected to the air supply tube 35.
[0033] When it is necessary to clean the oral cavity, the valve 37 is first closed to prevent the gas in the airbag 34 from leaking, and then the squeezing balloon 36 is continuously squeezed to make the airbag 34 gradually expand. When the airbag 34 expands, it will squeeze the hinged ends of the suction tube 31 and the connecting tube 32 to rotate, so that the originally inclined hinged ends gradually become parallel, so that one end of the connecting tube 32 extends out from the inside of the pharyngeal bending tube 1 and is located in the secretions. Then, the external negative pressure machine is connected to one end of the suction tube 31, and the secretions in the patient's oral cavity are extracted and cleaned by negative pressure, thereby reducing the risk of reflux and aspiration of secretions in the patient's oral cavity. After the cleaning is completed, the valve 37 can be opened to discharge the gas in the airbag 34, so that the airbag 34 gradually shrinks, and the hinged ends of the suction tube 31 and the connecting tube 32 lose squeezing and return to the inclined state, so that one end of the connecting tube 32 shrinks to the inside of the pharyngeal bending tube 1, thereby preventing the extended connecting tube 32 from causing damage to the patient's oral cavity.
[0034] Reference Figure 1 and Figure 3 The fixing component 6 includes a fixing column 61 fixedly connected in the groove 5, a fixing belt 1 62 is fixedly connected to the fixing column 61, a fixing belt 2 63 is fixedly connected to the end of the flange opening 2 away from the fixing belt 1 62, a Velcro thorn surface 64 is fixedly connected to one side of the fixing belt 2 63, and a Velcro fleece surface 65 is fixedly connected to one side of the fixing belt 1 62.
[0035] When using the device, first insert the pharyngeal flexion tube 1 into the patient's oral cavity, then wrap the fixing belt 1 62 and the fixing belt 2 63 inside the groove 5 around the back of the patient's neck. Since the fixing belt 1 62 and the fixing belt 2 63 are elastic, the tightness can be adjusted at will according to the patient's condition. Then, the Velcro thorn surface 64 and the Velcro fleece surface 65 are fitted together to fix the fixing belt 1 62 and the fixing belt 2 63 to each other, so as to prevent the pharyngeal flexion tube 1 from falling off from the oral cavity when the patient's head shakes, thereby improving the stability of the pharyngeal flexion tube 1.
[0036] Working principle: when using the device, firstly, the patient lies flat on the bed, and then the pharyngeal bending tube 1 is inserted into the patient's oral cavity, and the insertion is stopped after the patient's teeth reach between the two soft pads 8. The soft silicone tooth pad 7 can improve the protection of the patient's teeth, and the two soft pads 8 can limit the patient's teeth to ensure that the occlusal part is not easy to loosen and prevent the pharyngeal bending tube 1 from sliding in the patient's oral cavity. Then, the fixing belt 1 62 and the fixing belt 2 63 inside the groove 5 are wrapped around the back of the patient's neck. Since the fixing belt 1 62 and the fixing belt 2 63 are elastic, the tightness can be adjusted at will according to the patient's condition. Then the Velcro thorn surface 64 and the Velcro fur surface 65 are fitted together, so that the fixing belt 1 62 and the fixing belt 2 63 are fixed to each other, so as to prevent the pharyngeal bending tube 1 from falling off from the oral cavity when the patient's head shakes, thereby improving the stability of the pharyngeal bending tube 1. During use, the situation in the patient's oral cavity is monitored in real time by the micro camera 4. When it is observed that there is a lot of oral secretions, first The valve 37 is first closed to prevent the gas inside the airbag 34 from leaking, and then the balloon 36 is continuously squeezed to make the balloon 36 gradually expand. When the balloon 34 expands, it will squeeze the hinged ends of the suction tube 31 and the connecting tube 32 to rotate, so that the originally inclined hinged ends gradually become parallel, so that one end of the connecting tube 32 extends out from the inside of the pharyngeal bending tube 1 and is located in the secretions. Then the external negative pressure machine is connected to one end of the suction tube 31, and the secretions in the patient's oral cavity are extracted and cleaned by negative pressure, thereby reducing the risk of reflux and aspiration of secretions in the patient's oral cavity, and effectively improving the practicality of the device. When the cleaning is completed, the valve 37 can be opened to discharge the gas inside the airbag 34, so that the airbag 34 gradually shrinks, and the hinged ends of the suction tube 31 and the connecting tube 32 lose squeezing and return to the inclined state, so that one end of the connecting tube 32 shrinks to the inside of the pharyngeal bending tube 1, avoiding the extended connecting tube 32 from causing damage to the patient's oral cavity.
