[0024] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0025] like Figure 1As shown, the embodiment of the present invention provides a pharyngeal cavity inspection auxiliary device, comprising a through main tube 1 and trachea 3, both of which are made of soft materials (such as silicone, rubber, etc.). When the main tube 1 is inserted into the patient's pharyngeal cavity, the trachea 3 is inserted into the patient's pharyngeal cavity along with the main tube 1; an inspection channel is provided in the main tube 1, and the inner diameter of the inspection channel is sufficient to accommodate the insertion of an endoscope; an air bag 2 is installed at one end of the main tube 1 and the main tube 1 extends out of the air bag 2, and the end of the main tube 1 equipped with the air bag 2 serves as an insertion port. The use end of the patient's pharyngeal cavity; the airbag 2 is covered and installed on the outer surface of the main tube 1 and is not connected to the main tube 1, the airbag 2 is connected to the trachea 3, and the end of the trachea 3 away from the airbag 2 is connected and installed with an air pressure measuring device 6, and the air pressure measuring device 6 is equipped with an air pump and a pressure sensor, which can inflate / deflate the airbag 2 and measure the air pressure (the air pressure measuring device 6 indirectly measures the air pressure in the airbag 2 by measuring the air pressure in the trachea. The specific structure of the air pressure measuring device 6 has multiple embodiments in the prior art and will not be repeated here).

[0026] The pharyngeal cavity examination auxiliary device disclosed in the embodiment of the present utility model is used by inserting the use end of the main tube 1 into the patient's nostril and into the pharynx, and using the air pressure measuring device 6 to inflate the air bag 2 so that the air bag 2 expands and stretches to fit the user's pharyngeal cavity, so that the pressure of the patient's pharyngeal cavity can be accurately measured by the air pressure measuring device 6, and it is convenient to insert the endoscope into the inspection channel of the main tube 1 and reach the patient's pharyngeal cavity for further inspection, treatment and other operations.

[0027] Considering that saliva, sputum, and other secretions in the patient's pharyngeal cavity may affect the examination operation during the examination, in one specific embodiment, the pharyngeal cavity examination auxiliary device also includes a drainage tube 4. Drainage tube 4 is also made of a soft material. One end of drainage tube 4 extends to the use end of main tube 1, and the other end is connected to an external negative pressure pump. During the examination, saliva, sputum, and other secretions in the patient's pharyngeal cavity can be drawn out through drainage tube 4 by the negative pressure pump connected to drainage tube 4, thereby reducing the impact of saliva, sputum, and other secretions in the patient's pharyngeal cavity on measurement and examination. In a more specific embodiment, a detachable end cap 5 is provided at the end of drainage tube 4 away from the airbag 2. When the negative pressure pump is not connected, end cap 5 can be used to seal drainage tube 4.

[0028] In a specific embodiment, the Luer connector 7 is detachably connected between the trachea 3 and the air pressure measuring device 6. The Luer connector 7 can be adjusted to a connected or non-connected state (the specific structure of the Luer connector 7 has multiple embodiments in the prior art and will not be described in detail here). When measuring the patient's pharyngeal pressure, the Luer connector 7 is adjusted and maintained in a connected state. When inserting an endoscope into the main tube 1 to examine the patient, after using the air pressure measuring device 6 to inflate the airbag 2 and open the patient's pharyngeal cavity, the Luer connector 7 is adjusted to a non-connected state and the air pressure measuring device 6 is removed. While maintaining the inflation of the airbag 2 to facilitate the operation of the endoscope, the connection of the air pressure measuring device 6 is prevented from affecting the operation of the endoscope.

[0029] Considering that the insertion of the main tube 1 may cause abrasions to the patient's pharynx, in a specific embodiment, the end cut of the use end of the main tube 1 is smooth or has rounded corners, so as to minimize the concept that the insertion of the main tube 1 may cause abrasions to the patient's pharynx.

[0030] Considering that the aforementioned trachea 3 and drainage tube 4 need to be inserted into the patient's pharyngeal cavity in actual operation, in order to optimize the patient's experience and facilitate operation, in a specific embodiment, the trachea 3 and drainage tube 4 are attached and fixed along the main tube 1. In a preferred embodiment, holes are respectively opened on the main tube 1 to allow the air tube 3 and the drainage tube 4 to pass through the inspection channel of the main tube 1 from the outside to the inside, so that the air tube 3 and the drainage tube 4 can be more conveniently inserted into the patient's pharyngeal cavity along with the main tube; but in this embodiment, the air tube 3 and the drainage tube 4 are both inserted into the inspection channel. In order to reduce the impact on the insertion of the endoscope into the inspection channel, the inner diameter of the inspection channel needs to be larger. In a more preferred embodiment, the main tube 1 is a multi-channel design. In addition to the inspection channel, the interior of the main tube 1 also forms a drainage channel and / or an air supply channel parallel to the inspection channel (the design of forming parallel multi-channels in the tube has many embodiments in the prior art, which are not repeated here). The end of the drainage channel away from the air bag 2 is connected to the drainage tube 4, the end of the air supply channel close to the air bag 2 is closed, and the air supply channel is radially opened at a position close to the air bag 2 and is connected to the air bag 2. The end of the air supply channel away from the air bag 2 is connected to the trachea 3. In this embodiment, both the optimization of the patient's experience and the optimization of the doctor's operation can achieve better results.

[0031] The pharyngeal cavity inspection auxiliary device provided by the present invention provides an air bag at the use end of the main tube so that it can be extended into the patient's pharyngeal cavity, connects the air bag to an external air pressure measuring device that can inflate and deflate the air bag and measure the pressure, and provides an inspection channel for the endoscope to pass through in the main tube. While ensuring the accurate measurement of the pharyngeal cavity pressure, it can simplify subsequent pharyngeal cavity inspection, treatment and other operations, and has high practicality.

[0032] The above-described embodiments merely represent implementation methods of the present invention and should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
