Oral lavage auxiliary device for tracheal intubation patient

Abstract

The invention relates to the technical field of medical instruments, and concretely relates to an oral lavage auxiliary device for a tracheal intubation patient, which comprises an oral cavity fixatorbody, the oral cavity fixator body is fixedly connected with intubation tubes, two intubation tubes are provided, which are used for supporting a trachea and a lavage pipe; wherein the intubation tube penetrates through the front side wall and the rear side wall of the oral cavity fixator body, a convex ring is arranged on the inner wall of the intubation tube, a rubber ring is arranged above a convex ring, two groups of cylinders are arranged on the front side wall of the oral cavity fixator body, the two cylinders in each group are fixedly connected with two ends of an elastic lacing respectively, and the rear side wall of the oral cavity fixator body is fixedly connected with a bite block and a lip spacer. The oral lavage auxiliary device has the advantages that the oral cavity of a patient can be opened through the intubation tube, the trachea can be protected, the patient is prevented from biting the tongue or the trachea, the trachea and the lavage tube can be held tightly through the rubber ring, the trachea and the lavage tube are prevented from loosening back and forth, oral lavage nursing is facilitated for medical staff, and the device is simple in structure and convenient 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
