Description

Novel trachea cannula fixer

Technical Field

The utility model relates to the technical field of intubation auxiliary medical equipment in the rescue of severe patients, in particular to a novel trachea cannula fixer.

Background

The tracheal intubation is one of the most effective methods for ensuring the respiratory tract of a patient to be unobstructed, preventing aspiration, removing respiratory tract secretion, ensuring sufficient oxygen supply and rescuing the life of the patient, especially the critical illness state of the patient in the severe medical department (ICU), and is most common and important, and is used for treating the upper respiratory tract obstruction of the patient which can not be corrected in a short time; patients with impaired airway protective mechanisms and aspiration with reflux; airway secretion retention leads to pulmonary infection and lower respiratory obstruction, patients requiring clearance of airway secretions; patients with acute respiratory failure need invasive ventilation.

Proper cannula fixation is critical to ensure cannula success. Once the effective trachea cannula is not fixed, the trachea cannula can slip, all rescue treatments before a patient are zero, the trachea cannula is required to be fixed again, the rescue treatments are carried out again, and the trachea cannula can bring the risk of secondary airway mucous membrane damage to the patient. The importance of tracheal tube fixation is seen.

Currently, there are two fixing methods for the tracheal intubation commonly used clinically: one is a commercially available fixer, and the other is a fixing rod self-made by a syringe when fixing. However, the following different problems exist in the two fixing methods:

1. the horizontal position of the trachea cannula fixed by the outsourcing fixator is unchanged, so that the compression of the trachea cannula to the airway mucosa is always on one surface, and the risk of pressure injury of the airway mucosa is high.

2. The external fixator has the advantages that the compression position of the oral mucosa is unchanged, even if the oral care is finished or the fixator is removed to relieve the compression, the compression position is fixed again, and the compression position is unchanged, so that the current clinical patient with the oral mucosa pressure injury is obviously increased, and therefore, the external fixator is only used for newly admitted patients, and is discarded after being used for 24 hours, and the medical equipment is wasted.

3. When the self-made fixing rod is used, the manufacturing is troublesome every time, and after the manufactured fixing rod is fixed in the oral cavity of a patient, secretion in the oral cavity is not easy to suck from the oral cavity.

4. In addition, the self-made fixing rod is wound by the adhesive tape, and the adhesive tape can not be reused after being soaked by oral secretion, so that disposable consumable materials are wasted.
