Oral lavage auxiliary device for tracheal intubation patients

Abstract

The invention relates to the technical field of medical devices, in particular to an oral lavage auxiliary device for patients with tracheal intubation, which includes an oral retainer body, which is fixedly connected to an intubation tube, and two intubation tubes are respectively used to carry the trachea and the lavage tube, the intubation tube is set on the front and rear side walls of the oral fixator body, the inner wall of the intubation tube is provided with a convex ring, the rubber ring is arranged above the convex ring, and the front side wall of the oral fixation device body is provided with two sets of cylinders, The two cylinders in each group are respectively fixedly connected with the two ends of an elastic frenulum, and the rear side wall of the oral cavity retainer body is fixedly connected with the dental pad and the lip septum. Beneficial effects are: the invention can not only stretch the patient's mouth through intubation, but also protect the trachea to prevent the patient from biting the tongue or trachea, and can hold the trachea and lavage tube tightly through the rubber ring to prevent the trachea from irrigating. The washing tube is loosened back and forth, which is convenient for medical staff to perform oral lavage care, and has a simple structure and is easy to wear.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an oral lavage auxiliary device for patients with tracheal intubation. Background technique [0002] In recent years, tracheal intubation and mechanical ventilation have been widely used in critically ill patients. The oral cavity is one of the ways for pathogenic microorganisms to invade the body. Patients with orotracheal intubation are unable to eat, have limited chewing and swallowing functions, and the oral cavity is often open, which may easily cause dry oral mucosa or abnormal increase in oropharyngeal secretions. The self-cleaning effect of the oral cavity and the local mucosal resistance are weakened, resulting in a large number of bacteria multiplying in the oral cavity; the translocation of oral bacteria into the lower respiratory tract is one of the important causes of ventilator-associated pneumonia (VAP), and VAP is a serious symptom of mechanical ventilatio...

AI Technical Summary

Problems solved by technology

[0003] At the same time, due to the friction of tracheal intubation and tooth pads, it is very easy to cause local ulcers and erosions in the oral mucosa, which weakens the barrier effect; the application of a large number of antibiotics leads to bacterial flora imbalance, which promotes the abnormal reproduction of bacteria in the oral cavity

Applying traditional oral care methods to patients with orotracheal intubation, it is difficult to thoroughly and effectively clean the secretions accumulated in the patient's tongue, teeth and other parts of the oropharynx, which creates good breeding conditions for bacteria in the oral cavity

At present, it is believed that oral rinsing or oral scrubbing alone cannot effectively remove plaque or thoroughly clean special parts such as the oropharyngeal area

[0004] In the prior art, the oral cavity of patients with endotracheal intubation is nursed by the method of lavage, but in the actual operation process of oral lavage, there are situations where the patient bites the trachea or bites the tongue, resulting in medical accidents, so , the technical field urgently needs a kind of oral lavage auxiliary device for patients with endotracheal intubation
