Description

Trachea cannula
Technical Field
The utility model belongs to the technical field of medical instrument, especially, relate to a trachea cannula.
Background
The trachea cannula is a method for leading a special trachea catheter to pass through an oral cavity or a nasal cavity and enter a trachea or a bronchus through a glottis, provides the best conditions for unobstructed respiratory tract, ventilation and oxygen supply, respiratory tract suction and the like, and is an important measure for rescuing patients with respiratory dysfunction.
The trachea intubation is an important rescue technique commonly used in emergency treatment work, is one of the most widely, effectively and quickly applied means in respiratory tract management, is a basic skill which must be mastered by medical staff in special departments such as anesthesia departments and the like, and plays a vital role in rescuing the life of a patient and reducing the fatality rate.
There are many types of existing tracheal cannulas, for example, chinese patent publication No. CN102008773A discloses a tracheal cannula, which starts from 8 cm below the patient end cuff, circles along the circumference of the tube wall every 10 cm, and a convex point is arranged at every 90 degrees; the convex points are matched with the concave points of the disposable bite block which is commonly used at present and are tightly combined.
Most of the current clinical trachea cannulas have the following problems:
1) the intubation tube is not easy to fix, the original position is changed due to the suction of secretion and nursing work, even the intubation tube is detached, and the catheter has the possibility of being bitten, so that the ventilation is affected.
2) In the process of using the tracheal cannula, a patient is unconsciously bitten by the tracheal cannula under the condition of receiving anesthesia, so that the ventilation is not smooth, and the patient can be safe or not directly related to the success of the operation.
3) Because the trachea cannula is soft and can not be accurately positioned, the trachea cannula is not beneficial to medical care personnel, can quickly and accurately find the optimal position and can influence the smooth operation.
SUMMERY OF THE UTILITY MODEL
