Description
Technical field
The utility model is related to medical instrument more particularly to a kind of gasbag pressure adjusters for trachea cannula.
Background technology
The patient of trachea cannula needs to inflate to the air bag of trachea cannula, with what is heaved after being inserted into trachea cannula
Gap of the air bag between trachea cannula and tracheae is filled and closes.But the pressure of air bag can block greatly very much tracheae
The blood flow of mucous membrane easily causes ischemic, necrosis.Clinical experience thinks that the air pressure of air bag is suitable pressure in 25-30cm water columns
Power, this pressure will not cause the poor arterial inflow of mucous membrane, and the secretion on air bag will not be caused to enter lung.But it protects at present
Scholar carries out when inflating to air bag merely by experience, and air bag is located at tracheal strips, pressure of the air bag to inner surface of trachea mucous membrane
Whether compel suitable, can not intuitive judgment, often cause gasbag pressure too big, just cause tunica mucosa tracheae downright bad after a period of time.
Utility model content
In view of the above problems, the utility model is directed to a kind of tracheal intubation airbag pressure regulator, being capable of air flue
Overvoltage protection, when the pressure in air bag is more than predetermined value, adjuster will be opened, and airbag gas is discharged via it, thus will

Second end is detached with the circular ring shape inclined-plane of supervisor, while elongated through-hole at least part of annular wall enters truncated cone-shaped space, by
Air in this syringe can via supervisor's second end, annular wall, elongated hole, truncated cone-shaped space, supervisor's first end and enter
Air bag gas injection port；
Side pipe is formed in the side of supervisor, side pipe upper end closed, and lower end is connected to supervisor；Side pipe is formed in its side and is vented
Hole；Be formed further with second piston in side pipe, the upper end of second piston is connected to the lower end of second spring, second spring it is upper
End is supported on the inside of the upper end of side pipe；When second spring is less than scheduled pressure value by the upwards thrust of second piston, second
The connection of piston blocks gas vent and side pipe lower end；When second spring by second piston upwards thrust be more than predetermined pressure
When value, second spring is compressed, and second piston moves up, and gas vent is connected to side pipe lower end, thus the gas warp in air bag
By supervisor's first end, side pipe lower end, gas vent and be discharged to the outside.
Preferably, thin slice is installed in the gas vent, when there is gas to be flowed out from gas vent, thin slice shakes
It is dynamic, to send out prompt tone.
Preferably, second end of the gas vent towards the supervisor.
By the tracheal intubation airbag pressure regulator of the utility model, when nurse's gas injection into air bag, once pressure
More than predetermined value, just by above top to gas vent, thus gas can be discharged second piston by gas vent, will be under pressure drop
Come.

Specific implementation mode
In the following, the tracheal intubation airbag pressure regulator of the utility model is described in detail in conjunction with attached drawing.
The tracheal intubation airbag pressure regulator of the utility model comprising：Supervisor 10, side pipe 20.
Supervisor 10 is formed as hollow；The first end 11 of supervisor 10 is used to be inserted into the air bag gas injection port of trachea cannula, tool
Body is the inner space 11a for being inserted into first end 11；The second end 12 of supervisor 10 is used to be inserted into the nipple of syringe, specially injects
The nipple of device is inserted into the inner space 12a of second end 12, to carry out gas injection using syringe.
Supervisor 10 is in the circular ring shape inclined-plane 13 being formed with inside the side of second end 12 on the inside of supervisor, circular ring shape
Inclined-plane 13 limits truncated cone-shaped space 13a inside supervisor 10, and the diameter of 10 first end 11 of close supervisor of truncated cone-shaped space 13a is big
In the diameter close to 10 second ends 12 of supervisor；10 middle part of supervisor is formed further with inwardly projecting convex edge 14.
First piston 30 is installed in the truncated cone-shaped space 13a of supervisor 10.The first end of first piston 30 is formed as round
Column, second end are formed as circular cone shape；The of the columned first end diameter of first piston 30 less than truncated cone-shaped space 13a
The diameter of one end；The annular wall 31 for extending into supervisor is formed further in the second end of first piston 30, annular wall offers
Elongated through-hole 32.
The first spring 42 is provided between convex edge 14 and the first end of first piston 30, in the compressing of the first spring 42
Under, the second end and the circular ring shape inclined-plane 13 of supervisor 10 of the circular cone shape of first piston 30 mesh together；When the breast of syringe
When head is inserted into, nipple jacks up annular wall 31 so that first piston pressure 30 compels the first springs 42 and to supervisor 10 first end 11 direction
Mobile, the second end of the circular cone shape of first piston 30 is detached with the circular ring shape inclined-plane 13 of supervisor 10, while the length of annular wall 31
32 at least part of shape through-hole enters truncated cone-shaped space 13a, and thus the air in syringe can be via 10 second ends 12 of supervisor
(specifically by the inner space 12a of second end), annular wall inner space 33, the elongated hole 32 of annular wall, truncated cone-shaped space
13a, 10 first ends 11 are responsible for and enter air bag gas injection port.
Side pipe 20 is formed in the side of supervisor 10,20 upper end closed of side pipe, and lower end is connected to supervisor 10；Side pipe 20 is in its side
Portion forms gas vent 21；Second piston 50 is formed further in side pipe 20, the upper end of second piston 50 is connected to second spring
The upper end of 41 lower end, second spring 41 is supported on the inside of the upper end of side pipe 20；When second spring 41 is by second piston 50
When upwards thrust is less than scheduled pressure value (when air pressure is equivalent to 25-30cm water columns), second piston 50 blocks gas vent 21 and side
The connection of 20 lower end of pipe；When (the air bag when second spring 41 is more than scheduled pressure value by the upwards thrust of second piston 50
In pressure it is too big or when injecting too many gas), second piston 50 moves up, and second spring 41 is compressed, gas vent 21 with
Side pipe lower end is connected to, and thus the gas in air bag is via supervisor's first end 11 (being specially the inner space 11a of first end), side pipe
Lower end, gas vent 21 and be discharged to the outside.When the pressure recovery of air bag is to predetermined value, the pressure that second piston 50 is subject to becomes
Small, compressed second spring 41 again moves down second piston 50 so that and gas vent 21 is separated with 20 lower end of side pipe,
Stopping continues to be vented.
In order to significantly more provide warning, thin slice is installed in gas vent 21, is flowed out from gas vent when there is gas
When, thin slice vibrates, and to send out prompt tone, this point is similar to whistle, and thin slice is similar to beating reed.
Gas vent 21 is towards the second end 12 for being responsible for 10, therefore this end is operating side, it is easier to cause the nurse's of gas injection
Note that certainly, gas vent 21 can also be towards first end, as shown in the figure.
By the tracheal intubation airbag pressure regulator of the utility model, air bag during inflating can effectively be avoided to be filled
Enter excess air, prevents the poor arterial inflow of tunica mucosa tracheae from generating.
