一种新型咽鼓管吹张器A new type of Eustachian tube inflator

技术领域technical field

本实用新型涉及医疗器械领域，特别是一种新型咽鼓管吹张器。The utility model relates to the field of medical equipment, in particular to a novel eustachian tube inflator.

背景技术Background technique

咽鼓管呈弓状弯曲，整个管道长约35～39毫米，由软骨部与骨部两部分所组成。它的外1/3为骨部，内则有颈内动脉，在鼓室前壁的偏上部是鼓室口；内2/3为软骨部，内侧端的咽口位于鼻咽部的侧壁，具体位置是在下鼻甲后端的后下方。骨性部是管的外侧较短的部分，其鼓室端开口于鼓室的前壁；软骨部经咽鼓管咽口，开口于鼻咽部的侧壁。软骨部平时闭合，仅在吞咽或呵欠时开放，以平衡中耳和外耳的气压，有利于鼓膜的正常振动。由于咽鼓管与鼻咽部相通，故咽部感染易沿咽鼓管侵入鼓室，引起中耳炎。The Eustachian tube is curved in an arcuate shape. The entire tube is about 35 to 39 mm long and consists of two parts: cartilage and bone. Its outer 1/3 is the bony part, the inner carotid artery is located, and the upper part of the anterior wall of the tympanic cavity is the tympanic orifice; the inner 2/3 is the cartilage part, and the pharyngeal orifice at the inner end is located on the side wall of the nasopharynx. The specific location It is posterior and inferior to the posterior end of the inferior turbinate. The bony part is the short outer part of the tube, and its tympanic end opens to the anterior wall of the tympanic cavity; the cartilage part passes through the pharyngeal orifice of the Eustachian tube and opens into the lateral wall of the nasopharynx. The cartilage is usually closed, and only opens when swallowing or yawning to balance the air pressure in the middle ear and outer ear, which is conducive to the normal vibration of the tympanic membrane. Because the Eustachian tube communicates with the nasopharynx, pharyngeal infection easily invades the tympanic cavity along the Eustachian tube, causing otitis media.

治疗咽鼓管功能障碍的方法有药物保守法、咽鼓管吹张法和外科手术治疗法等，主要生理功能是调节中耳腔内外压力平衡。如果咽鼓管功能出现障碍，其中绝大部分是指延迟开放，会导致耳鸣、耳闷、听力下降或者中耳炎等病变。咽鼓管吹张法有捏鼻闭嘴鼓气法、波氏球吹张法、导管吹张法。目的是通过气压迫使咽鼓管开放，从而达到中耳内外压力平衡的目的。The methods of treating Eustachian tube dysfunction include conservative drug method, Eustachian tube inflating method and surgical treatment. The main physiological function is to adjust the pressure balance inside and outside the middle ear cavity. If the Eustachian tube is dysfunctional, most of them refer to delayed opening, which will lead to tinnitus, ear fullness, hearing loss, or otitis media and other diseases. The Eustachian tube inflating method includes pinching the nose, closing the mouth and inflating the method, the Bauer's ball inflating method, and the catheter inflating method. The purpose is to force the Eustachian tube to open through air pressure, so as to achieve the purpose of equalizing the pressure inside and outside the middle ear.

咽鼓管吹张法中波氏球吹张法为较为常用的一种方法，该方法需要从病人鼻腔插入软管，寻找到咽鼓管鼻咽开口后通过挤压波氏球对咽鼓管施加正压给气，以促进咽鼓管的开放。目前临床上使用的咽鼓管吹张器中的软管是裸露在空气外面，容易受潮腐蚀，不便保存，并且不能够控制导管的长短来控制波氏球的施压给气，治疗过程中若操作不慎可能造成鼻腔和咽鼓管口的创伤。In the Eustachian tube inflating method, the Bauer's ball inflating method is a more commonly used method. This method requires inserting a flexible tube from the patient's nasal cavity, finding the nasopharyngeal opening of the Eustachian tube, and applying a positive pressure to the Eustachian tube by squeezing the Bauer's ball. Pressure is given to facilitate the opening of the Eustachian tube. The soft tube in the Eustachian tube inflator currently used in clinic is exposed to the outside of the air, which is easily corroded by moisture, inconvenient to store, and cannot control the length of the tube to control the pressure and air supply of the Bauer's bulb. Inadvertent manipulation may cause trauma to the nasal cavity and the orifice of the Eustachian tube.
