Description

Tracheal cannula fixer

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a tracheal cannula fixer.

Background

Trachea cannula is an effective method for establishing artificial airway when clinically rescuing cardiac arrest and other critical patients. However, the trachea cannula must be well fixed to ensure effective ventilation of the patient, and once the trachea cannula is pulled out, the patient is injured again, such as untimely detection or improper treatment, and even death due to acute hypoxia asphyxia can be caused.

At present, tracheal intubation is generally fixed in hospitals by two ways, the first way is that after successful intubation is determined, a bite block is placed between upper and lower incisors of a patient, the tracheal intubation and the bite block are bound and fixed side by an adhesive tape, and finally, a trachea is fixed on the cheek part of the patient by the adhesive tape; the fixing mode has the following defects: 1. due to the secretion of facial skin grease, the adhesive plaster viscosity is easy to weaken or lose, so that the connection is not firm, and the catheter is easy to loosen and dislocate; 2. the depth of the catheter can not be adjusted according to the requirement after the catheter is fixed; 3. the sputum in the oral cavity of the patient is inconvenient to clean; 4. the adhesive plaster is fixed by adhesive, so that the phenomena of skin allergy and the like of partial patients are easily caused. The second is to use the trachea cannula fixer to fix the trachea cannula fast, safely, stably to effectively overcome the shortcoming of adopting the fixed intubate of the first fixed mode, also greatly made things convenient for medical personnel's operation, reduced postoperative complication, reduced the probability of retrograde infection, increased patient's comfort level. However, the tracheal cannula fixator commonly used in the hospital still has the following defects: 1. the oral cavity cleaning window is small, so that the oral cavity of a patient is inconvenient to clean effectively when the fixator is worn; 2. the fixing position of the trachea is not firm enough, and the trachea is easy to slide in the using process; 3. the part close to the face is made of harder materials and cannot be adjusted according to the face shape of a patient, so that the comfort of the patient is not enough, and the risk of pressure sores and the like is high; 3. in the treatment process of wearing the fixator, the difficulty in cleaning sputum, saliva and other liquid in the oral cavity of a patient is high. There is therefore a need for an endotracheal tube holder that effectively overcomes the above drawbacks.

The invention aims at the problems and provides a tracheal cannula fixer.
