Trachea cannula fixing device

Abstract

The invention provides a trachea cannula fixing device, which comprises a dental pad, wherein the dental pad comprises an occlusion part and a cannula fixing part; the occlusion part is matched with teeth on one side of an oral cavity; the cannula fixing part is connected to the occlusion part, is positioned at one end of the occlusion part and projects towards an outer side; the cannula fixing part is provided with an axial through hole, and projects outwards; both sides of the occlusion part are connected with fixing bands; the dental pad is made of an elastic material. The trachea cannula fixing device has the advantages of simple structure, stable and reliable fixing way, small oral cavity occupation area and convenience in clearing excreta in the oral cavity; meanwhile, the trachea cannula fixing device is prevented from hurting the teeth of a patient, and is suitable for wide clinical application.

Description

technical field [0001] The invention relates to a medical device, in particular to a tracheal intubation fixing device. Background technique [0002] At present, there are mainly two ways to fix the tracheal intubation. The first is to stick it on the face with adhesive plaster, that is, the adhesive plaster fixation method; the second is to use a fixator to fix it. [0003] The first method has the following defects: 1. It is easy to damage the skin of patients, especially elderly patients or patients with facial injuries and facial edema; 2. The fixation effect is limited, and when applied to patients with high fever, it is easy to lose the adhesive tape due to sweat. 3. Two people are required to cooperate in oral care (one person supports the tube, one person operates), which is a waste of manpower; 4. The oral cavity is sealed by adhesive tape, which is inconvenient to clean up oral secretions; 5. Repeatedly sticking the tracheal tube will cause Glue remains on the pas...

Problems solved by technology

[0003] The first method has the following defects: 1. It is easy to damage the skin of patients, especially elderly patients or patients with facial injuries and facial edema; 2. The fixation effect is limited, and when applied to patients with high fever, it is easy to lose the adhesive tape due to sweat. 3. Two people are required to cooperate in oral care (one person supports the tube, one person operates), which is a waste of manpower; 4. The oral cavity is sealed by adhesive tape, which is inconvenient to clean up oral secretions; 5. Repeatedly sticking the tracheal tube will cause Glue remains on the sticking part of the endotracheal tube, and some oral secretions are easy to stay on it, forming a bacterial culture medium, causing the patient to have the risk of infection

[0004] Existing fixers have horizontal spiral type and vertical spiral type, both of which have the following defects: 1, the tooth pad is very hard, which is easy to damage the patient's front teeth; 2, it needs to be taken off every time oral care is performed, And it needs two people to operate (one person does oral care, one person assists the tracheal intubation to prevent slipping), which is a waste of manpower; 3. It takes up too much area in the oral cavity, which is inconvenient to clean oral secretions; Strong, the source of its fixing power is the friction of two sides (one side of the fitting side is covered with barbs, and the other side is the chorion surface), and it is easy to lose its function after long-term use
