Description

Teeth cushion for trachea cannula

Technical Field

The utility model relates to the technical field of medical equipment.

Background

The trachea cannula is a technology of placing a special trachea catheter into a trachea through a glottis, and the technology can provide optimal conditions for smooth air passage, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like.

The trachea cannula technology becomes an important measure in the process of rescuing patients with cardiopulmonary resuscitation and critical patients accompanied with respiratory dysfunction, and plays a vital role in rescuing the lives of the patients and reducing the fatality rate. And the tracheal cannula can timely suck out the endocrine or foreign matters in the trachea, prevent the foreign matters from entering the respiratory tract, keep the respiratory tract smooth, effectively ventilate manually or mechanically, and prevent whether the patient is in time in the process of oxygen deficiency and carbon dioxide retention, which is directly related to whether the rescue is successful or not, whether the patient can safely transport the tracheal cannula or not and the prognosis condition of the patient.

In order to ensure the smoothness and the position fixation of the tracheal intubation catheter, a bite block is generally clinically placed between the upper and lower incisors of a patient to prevent the patient from biting the catheter flatly. A common tracheal intubation bite block structure generally comprises a bite block main body, a baffle plate and an air bag. Between the dentition about the patient was put into to the bite-block main part, played the supporting role to prevent that the tooth from biting bad endotracheal tube, sputum hole is inhaled for lining up in the middle part of the bite-block main part, and the front end of bite-block has the tooth guard baffle for fixed endotracheal tube prevents that endotracheal tube from shifting, and the gasbag is located the rear end of tooth guard baffle, wraps up around the bite-block main part.

However, the volume of the existing bite block is generally arranged on two sides of a tracheal intubation tube respectively, so that the whole volume is large, the mouth opening degree of a patient is large, and the mouth opening degree is easy to cause the occlusion discomfort of the upper and lower jaws of the patient after operation.

Generally use medical adhesive plaster to bind bite-block and trachea cannula clinically, then fix bite-block and trachea cannula in patient's face through medical adhesive plaster. This kind of mode is troublesome poeration not only, and fixed effect is poor, and easy pine takes off to influence patient's travelling comfort, increase medical personnel's the nursing degree of difficulty. Particularly, for patients with maxillofacial trauma, the fixing method of adhering and fixing the face with a medical adhesive plaster or fixing the tracheal catheter with a rope and a thin wire and tying the tracheal catheter behind the ear has the possibility of not firm fixation and polluting the wound and avoiding the unfavorable debridement.

In addition, the tongue body is easy to fall back when the patient is in a coma and is not intubated. For patients with jaw face trauma, sputum, blood and other contaminants enter the oral cavity and are choked into the airway, which may cause asphyxia.

In summary, it is an urgent technical problem to provide a bite block for endotracheal intubation, which has a smaller size, can support the tongue body, and is easier to fix the endotracheal intubation.
