本发明属于医疗器械技术领域，具体是涉及一种改进牙垫。The invention belongs to the technical field of medical devices, and in particular relates to an improved tooth pad.
背景技术Background technique
为防止重症监护或麻醉患者的口插管被患者咬扁进而影响通气功能，通常需要在患者口中嵌入牙垫撑开口腔，保持上下门齿的间距。参看图1，牙垫的结构包括圆筒形的手持部和咬合部以及两者连接处的卡棱，咬合部的上下两侧设有平行且对称的咬合平面，卡棱的右侧设有容纳口插管的弧形槽，弧形槽与卡棱的基圆相切，且弧形槽与卡棱基圆的中心连线平行于咬合平面，卡棱上设有穿绳孔，捆扎绳穿过穿绳孔先是将口插管绑缚在牙垫上，再绕患者头部进行捆绑固定。In order to prevent the oral intubation tube of intensive care or anesthesia patients from being bitten by the patient and affecting the ventilation function, it is usually necessary to insert a tooth pad in the patient's mouth to open the mouth and maintain the distance between the upper and lower incisors. Referring to Figure 1, the structure of the tooth pad includes a cylindrical handle part, an occlusal part, and a card edge at the junction of the two. Parallel and symmetrical occlusal planes are provided on the upper and lower sides of the occlusal part, and the right side of the card edge is provided with an accommodating The arc groove of the intubation tube, the arc groove is tangent to the base circle of the card edge, and the line connecting the center of the arc groove and the base circle of the card edge is parallel to the occlusal plane. Through the threading hole, the oral intubation tube is first bound to the dental block, and then bound and fixed around the patient's head.
牙垫上的卡棱通常做成圆形，为便于吸痰和口腔护理，圆形卡棱的直径一般为2-3厘米，小于人们张大状态的嘴巴。尽管有捆扎绳辅助，但当患者躁动或打呵欠而张大嘴巴时，还是很容易将卡棱含进口中，圆形卡棱会蹭破患者口腔和牙齿，进而感染和形成溃疡，此类患者本身抵抗力低，局部的感染会导致血源播散。The ribs on the tooth pad are usually made into circles. For the convenience of suctioning and oral care, the diameter of the circular ribs is generally 2-3 centimeters, which is smaller than the mouth of people's open state. Even with the help of a binding rope, when the patient is agitated or yawns and opens his mouth wide, it is still easy to contain the cardin in the mouth. The circular cardin will rub against the patient's mouth and teeth, and then infect and form ulcers. Such patients themselves Low resistance, local infection can lead to hematogenous dissemination.
