Description
Technical field
This utility model relates to medical apparatus and instruments, specifically a kind of trachea artificial airway.
Background technology
Artificial airway mainly contains tracheal intubation and tracheostomy cannula, and they all have use widely in serious symptom medical science section, Anesthesia Department, Pneumology Department, emergency department.The primary structure of existing artificial airway is: the leading section of a main pipeline has air bag in, has passed into gas-adding pipe in the tube wall of main pipeline, and the front end of gas-adding pipe communicates with interior air bag, and the rear end of gas-adding pipe is stretched out at main pipeline outer and connect with an external air bag.This artificial airway is placed in after in the trachea of human body, by balloon occlusion trachea in inflating, realizes stoping the secretions of pars oralis pharyngis to be strayed into air flue, after it has laid in trachea, clinically at interval of 4 hours by interior air bag deflation once, and then inflates.In this artificial airway, do not have the setting of gasbag pressure in energy Real-Time Monitoring, it is in laying or using, and needs to use pressure monitor control or detect the air pressure of interior air bag, it is in Clinical practice, usually judges whether the pressure of interior air bag meets the requirements by rule of thumb by medical personnel.The shortcoming that above-mentioned this artificial airway exists is: to lay or in use procedure, Reusability pressure monitor, operation comparatively bothers, and the amount of labour is comparatively large, takies the working time more; To lay or in use procedure, if judge completely by rule of thumb, whether the pressure of interior air bag meets the requirements, once there is error, can cause adverse consequences, can cause complication time serious.
Utility model content
The purpose of this utility model be to provide a kind of can the artificial airway of Real-Time Monitoring gasbag pressure, this artificial airway is laying or in use procedure, need not by external equipment, and whether the pressure that can monitor interior air bag intuitively meets the requirements.
For achieving the above object, this utility model adopts following scheme: can the artificial airway of Real-Time Monitoring gasbag pressure, it has a main pipeline, the leading section of main pipeline has air bag in, gas-adding pipe has been passed in the tube wall of main pipeline, the front end of gas-adding pipe communicates with interior air bag, the rear end of gas-adding pipe is stretched out outside main pipeline, and connect with an external air bag, external air bag is connected to a piston cylinder, at piston cylinder built with a piston and elastomer, the inner chamber of piston cylinder is separated into inlet chamber and discharge chamber by piston, the inlet chamber of piston cylinder communicates with the inner chamber of external air bag, piston cylinder has the steam vent communicated with discharge chamber, the side of piston is connected with an indicating arm, indicating arm stretches out piston cylinder, indicating arm is furnished with along its length the scale be in turn connected to form by the color section that some colors are different.
From such scheme, because external air bag communicates with interior air bag, and piston cylinder communicates with external air bag, therefore, interior air bag in the deflated condition, air pressure in interior air bag can be applied on the piston in piston cylinder, piston is issued to balance at the gas pressure of elastomer and interior air bag, when in interior air bag, air pressure changes, piston can be moved, observe according to the scale on indicating arm the length that it stretches out piston cylinder, whether meet the requirements after the air pressure can judging in interior air bag changes, so that the air pressure in adjustment timely in air bag.
This utility model is simple and reasonable for structure, and it is convenient, accurately to observe, and it can remind medical personnel to adjust air pressure in interior air bag timely, and can alleviate the amount of labour of medical personnel's monitoring.
Accompanying drawing explanation
The structural representation of Fig. 1 this utility model one embodiment;
The A portion enlarged drawing of Fig. 2 Fig. 1.
Detailed description of the invention
This utility model is further illustrated below in conjunction with embodiment and accompanying drawing.
See Fig. 1, Fig. 2
What this utility model provided can the artificial airway of Real-Time Monitoring gasbag pressure, it has a main pipeline 1, the leading section of main pipeline 1 has air bag 2 in, gas-adding pipe 3 has been passed in the tube wall of main pipeline 1, the front end of gas-adding pipe 3 communicates with interior air bag 2, the rear end of gas-adding pipe 3 is stretched out outside main pipeline 1, and connect with an external air bag 4, external air bag 4 is connected to a piston cylinder 5, at piston cylinder 5 built with piston 6 and an elastomer, the inner chamber of piston cylinder 5 is separated into inlet chamber 5b and discharge chamber 5c by piston 6, the inlet chamber 5b of piston cylinder communicates with the inner chamber of external air bag 4, piston cylinder 5 has the steam vent 5a communicated with discharge chamber 5c, the side of piston 5 is connected with an indicating arm 8, indicating arm 8 stretches out piston cylinder 5.Indicating arm 5 is furnished with along its length the scale become by different color section b, the c of three colors, D-shaped.In the present embodiment, described elastomer is spring 7.Spring 7 is arranged on 5c in the discharge chamber of piston cylinder 5, when the gas pressure in interior air bag 2 is on piston 6, and spring 7 pressurized.In addition, spring 7 also can be arranged in the inlet chamber 5b of piston cylinder 5, and when spring is arranged in inlet chamber, its two ends are connected with piston cylinder 5 and piston 6 respectively, when the gas pressure in interior air bag 2 is on piston 6, and spring 7 tensions.
On indicating arm, from top to bottom three different colours section b, c, d can be chosen as redness, green, white respectively, spring is selected: after the gas pressure in interior air bag 2 makes the elastic deformation of spring 7 pressurized on piston 6 according to following requirement, the color segment d of the white on indicating arm 8 stretches out piston cylinder, or the section color segment c of green and the color segment d of white stretches out piston cylinder, or the color segment d of the color segment b of redness, green color segment c and white is when all stretching out piston cylinder, show that the air pressure in interior air bag is on the low side respectively, normal, higher.
From Fig. 1, Fig. 2, the artificial airway that this utility model provides can be used as tracheal intubation or tracheostomy cannula uses, this artificial airway is when laying or in using, the length of being stretched out piston cylinder by indicating arm forms visual signal, can judge whether the pressure of interior air bag meets the requirements.Namely, when the color segment d of the white on indicating arm stretches out, pressure in representing in air bag is on the low side, need inflation, when the color segment c of the green on indicating arm stretches out, the pressure in representing in air bag is normal, when color segment b red on indicating arm all stretches out, pressure in representing in air bag is higher, needs venting.
