Description

Straight type multi-cavity high-frequency medical whistle assisting in judging position of connecting pipe conduit

Technical Field

The utility model relates to the technical field of medical equipment, specifically a supplementary medical whistle of straight multicavity high frequency who judges connecting pipe position.

Background

Currently, there are eight methods for auxiliary judgment of the position of the tracheal catheter clinically, which are respectively: firstly, when the trachea is intubated, the tube tip of the trachea intubated is witnessed to enter the glottis from the position between the vocal cords by a laryngoscope. The method needs a laryngoscope, a visible laryngoscope and the like, and is not suitable for difficult intubation and transnasal tracheal intubation; and secondly, observing the fluctuation of the thorax and the condition of the stomach during ventilation, and if the fluctuation of the thorax is not obvious after ventilation, the abdomen is obviously swollen and the content in the trachea and the stomach refluxes, the thorax and the stomach are definitely not in the airway. The method takes time to observe the fluctuation of the thorax and the condition of the stomach, and is difficult to observe especially when the fluctuation of the thorax of a patient is weak. When the light of the intubation field is insufficient, the fluctuation of the thorax and the condition of the stomach are more difficult to observe; and thirdly, auscultating the breathing sounds of the chest and the abdomen during ventilation, and considering that the tracheal catheter is positioned in the trachea if the breathing sound of the chest is strong and the upper abdomen is not obvious. If the noise of the intubation site is large, the breathing sound is difficult to hear clearly, and a stethoscope is needed; and fourthly, the thorax is squeezed, the patient with spontaneous respiration hears the respiration sound through the tracheal catheter port, and the obvious airflow indicates that most of the patients are in the trachea. This method requires time and effort to compress the thorax. If the noise of the intubation site is large, it is difficult to hear the breath sound clearly. Intubators listen to breath sounds through the mouth of the tracheal catheter, and if patients have respiratory infectious diseases, the intubators are easy to suffer diseases; and fifthly, the breathing machine is connected to see the flow velocity waveform of the exhaled breath, and if the flow velocity waveform is good, the breathing machine is prompted to be in the trachea. The method needs a breathing machine, has obviously limited application field and is not suitable for being applied to most scenes; sixthly, monitoring the end-tidal carbon dioxide of the patient, if the patient is inserted into an trachea, the carbon dioxide is displayed during visible expiration, the end-tidal carbon dioxide of the patient needs to be monitored, the application field is obviously limited, and the method is not suitable for being applied to most scenes; seventhly, performing emergency bedside fiberoptic bronchoscopy examination, and determining that the patient is in the trachea if the carina and the bronchial opening are visible. The method needs a breathing machine, has obviously limited application field and is not suitable for being applied to most scenes; and eighthly, performing imaging examination such as chest radiography and chest CT examination. The method needs to move the patient or the equipment for examination, is time-consuming and labor-consuming, and is not suitable for rescuing or operating intubating cases.

The method for judging the position of the tracheal catheter is not suitable for rescuing the severe environment, such as the insufficient light condition or the emergency blind intubation through the nose with noisy environment. Therefore, it is necessary to design a straight multi-cavity high-frequency medical whistle for assisting in judging the position of the connecting pipe.
