Description

Bite-block for protecting trachea cannula

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to a bite block for protecting a tracheal cannula.

Background

The trachea cannula technology is an important measure for treating patients with general anesthesia, dyspnea, cardiopulmonary resuscitation, respiratory dysfunction and the like. The tracheal catheter is put into the trachea from the oral cavity through the glottis, provides the best treatment conditions for patient airway smoothness, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like, and is a widely applied treatment means in respiratory tract management.

Endotracheal tube soft texture, in clinical care, in order to prevent that patient's anesthesia from waking up or stinging and close endotracheal tube because of reasons such as irritability, discomfort, after the trachea cannula art is accomplished, often adopt the bite-block wing to arrange in the outer fringe of upper and lower dentition, prevent that the bite-block from shifting, the bite-block card is used for fixed endotracheal tube, prevents that endotracheal tube from shifting. Or a hard bite block is filled between the upper teeth and the lower teeth of the patient; the tracheal catheter and the tooth pad are respectively fixed on the face of a patient through adhesive tapes, inch belts and the like, and the operation is complicated. Due to individual differences of patients, particularly some patients are limited by facial skin, and are difficult to fix by conventional methods such as adhesive plaster.

The existing bite block has the following defects:

1. the material is hard plastic, so that the hardness is high, the elasticity is not high, and the discomfort of a patient is easily caused;

2. when the patient bites the bite block, the upper wing and the lower wing of the bite block are clamped between the labial teeth of the patient, so that the fixation effect is achieved. The edges of the upper wing and the lower wing of the bite block are sharp and are in a thin sheet structure, so that the oral cavity of a patient is easily damaged;

3. after part of the bite-block is inserted into the oral cavity of the patient, the tracheal cannula is manually placed and is fixed on the side surface of the bite-block in an exposed manner, the tracheal cannula is not good in protection effect, and the tracheal cannula is easy to bend and deform due to the bite of the patient, so that an ideal effect cannot be achieved;

4. the tongue of a part of users who are not awake is used for propping the tooth pad, so that the tooth pad is easy to be dislocated, the tooth pad is easy to slip off, and the corresponding use purpose of the tooth pad is not achieved.
