Description
Technical Field
The utility model relates to a trachea cannula capable of observing the pressure of an air sac.
Background
The trachea cannula is a method for placing a special trachea catheter into a trachea or a bronchus through an oral cavity or a nasal cavity and 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.
In the prior art, a common structure of an endotracheal intubation is shown in fig. 1, two ends of an indicator balloon 2 are respectively connected with a one-way valve 1 and an inflation tube 3, the inflation tube 3 is communicated with a cuff 5 and an airbag 6 through a side hole 4 on the cuff 5, and an intubation tube 7 passes through the center parts of the cuff 5 and the airbag 6. When the air-inflated balloon inflating device works, air is sucked by the injector and injected into the one-way valve, and the air reaches the balloon through the indicating balloon, the inflating tube and the side hole and inflates and expands the balloon. The inflated air bag can play the roles of fixing the intubation tube and sealing the trachea of the human body.
The pressure of the balloon must be strictly controlled: the research result shows that when the pressure of the air bag exceeds 30cmH 2 When the column is 0, the blood flow of mucosa capillaries begins to be reduced, and the blood supply of airway mucosa is influenced; when the pressure of the air bag exceeds 50cmH 2 0 columns, blood flow is completely blocked; the tracheal mucosa is pressed for a certain time, so that ischemic injury and even necrosis of the tracheal mucosa can be caused, and tracheoesophageal fistula can occur in severe cases. However, the pressure of the air bag cannot be too low, and the air bag can be deflated and sucked by mistake once the air bag is not inflated enough.
The air sac cannot be observed visually when the tracheal cannula is used. The method for observing and adjusting the pressure of the air sac by the tracheal intubation in the prior art is to observe the expansion degree of the indicating air sac. However, the method is very crude and uncertain, and needs an experienced doctor and nurse for use.

Further, the inflation tube 3, the cuff 5 and the air bag 6 are integrally formed.
Further, the cuff 5 and the air bag 6 are integrally formed, and the inflating tube 3 is communicated with the cuff 5 through a side hole 4 on the cuff 5.
Furthermore, the indication shell 8 is made of a hard transparent material.
Furthermore, a plurality of scale marks are arranged on the indication shell 8.
Further, the indication shell 8 is provided with 3 scale marks, which are a first scale mark 14, a second scale mark 15, and a third scale mark 16.
The utility model has the advantages that:
1. the utility model evaluates whether the pressure of the air bag is proper or not through the height of the telescopic inner bag in the indication shell, has the technical advantage of convenient observation and adjustment, and can be correctly operated and used by doctors and nurses with poor experience, even family members;
2. the utility model discloses during the use, 3 scale marks can set up different colours to more audio-visual observation and the size of instruction gasbag pressure.

Detailed Description
Example 1
As shown in fig. 2, the trachea cannula capable of observing the pressure of the air bag comprises a one-way valve 1, an inflation tube 3, a side hole 4, a cuff 5, the air bag 6 and an intubation tube 7, wherein the one-way valve 1 is hermetically connected with an indication shell 8, the indication shell 8 is transparent, hollow and provided with a through hole 9, and an air passage 10 is arranged in the side wall of the indication shell 8; the one-way valve 1 is provided with a first air outlet hole 11 and a second air outlet hole 12, the first air outlet hole 11 is communicated with the air passage 10, and the second air outlet hole 12 is communicated with the telescopic inner bag 13; the telescopic inner bag 13 is positioned inside the indicating shell 8; the other end of the air passage 10 is communicated with an inflation tube 3, the inflation tube 3 is communicated with a cuff 5 through a side hole 4 on the cuff 5, the cuff 5 is communicated with an air bag 6, and a cannula 7 penetrates through the center parts of the cuff 5 and the air bag 6; the indication shell 8 is provided with 3 scale marks, namely a first scale mark 14, a second scale mark 15 and a third scale mark 16.
