Negative pressure nasal aspirator airbag anterior rhinoscope

Abstract

The invention provides a negative-pressure nasal aspirator type gasbag anterior rhinoscope, which comprises a rhinoscope bracket, a supporting gasbag, a conveying hose, a gas charging module, a negative-pressure collecting box and a control valve; the rhinoscope bracket comprises a handle and an opening-closing clamp; a rotary structure is designed on the handle; an absorbing hole is designed in an inner side surface of a jaw of the opening-closing clamp; a drainage channel is designed inside the opening-closing clamp; a fixed groove is designed between field angles of the opening-closing clamp; a gas inlet and a gas outlet are designed in the supporting gasbag; the control valve is designed in the gas inlet; a gas inlet and a gas outlet are designed in the gas charging module; a gas outlet and a liquid inlet are designed in the negative-pressure collecting box; the liquid inlet of the negative-pressure collecting box is fixedly equipped with the control valve; and the control valve uses a one-way valve device. The negative-pressure nasal aspirator type gasbag anterior rhinoscope provided by the invention can be used for positioning by accurately controlling an opening angle, and also can simultaneously clear secreta in a nasal cavity of a patient, is simple in structure, and is convenient to use.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an anterior rhinoscope. Background technique [0002] Anterior rhinoscopy is a method of observing the nasal cavity through the anterior opening of the nose. With the help of the light reflected by the mirror, the color of the mucous membranes on the walls of the nasal cavity, the size of the middle and inferior turbinates, the shape of the nasal septum, secretions in the nasal cavity, and whether there are tumors or foreign objects can be observed. In order to achieve the purpose of diagnosing diseases; the front rhinoscope is a medical tool used by the user to check the patient's nasal cavity. The front end of the front rhinoscope stretches the patient's anterior nares to expose more of the inside of the patient's nasal cavity, so that the user can clearly observe the condition inside the patient's nasal cavity and make a diagnosis, so as to provide corresponding treatment fo...

[0002] Anterior rhinoscopy is a method of observing the nasal cavity through the anterior opening of the nose. With the help of the light reflected by the mirror, the color of the mucous membranes on the walls of the nasal cavity, the size of the middle and inferior turbinates, the shape of the nasal septum, secretions in the nasal cavity, and whether there are tumors or foreign objects can be observed. In order to achieve the purpose of diagnosing diseases; the front rhinoscope is a medical tool used by the user to check the patient's nasal cavity. The front end of the front rhinoscope stretches the patient's anterior nares to expose more of the inside of the patient's nasal cavity, so that the user can clearly observe the condition inside the patient's nasal cavity and make a diagnosis, so as to provide corresponding treatment for the patient; generally Most of the current nose mirrors use this principle for diagnosis. However, such tools require the user to manually adjust the opening angle of the front nose mirror. When the front nose mirror is opened, it needs to be positioned to maintain a proper opening Open angle for diagnosis; the front nose mirrors currently used in medical treatment cannot be well positioned at each opening angle, which will cause incomplete observation by the user, or cause discomfort to the patient, thereby affecting the diagnosis of the patient ;During the observation process of the front rhinoscope, there may be accumulation of secretions in the patient's nasal cavity, so that the user cannot observe the information inside the patient's nasal cavity, so the user needs to clean up the secretions in the patient's nasal cavity, After the cleaning is completed, the observation of the front nose mirror will be carried out again. Such an operation will greatly increase the time for the diagnosis of the patient, which will not only affect the diagnosis of the patient, but will even cause harm to the patient. Therefore, there are defects.
