Description
Technical Field
The invention relates to the field of medical appliances, in particular to a tracheal intubation catheter with a function of monitoring the pressure of an air bag.
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.
The air bag is inflated to the degree of just closing the gap between the catheter and the tracheal wall, the catheter is easy to fall off when the inflation quantity is insufficient, respiratory tract secretion flows downwards along the wall of the air bag, large amount of air is blindly injected into the air bag to cause the ischemic necrosis of the tracheal wall, and the pressure of the air bag is required to be kept to be 25-35 cmH20 conventionally. However, in clinical practice, the air sac is gradually loosened for a while, and the gap between the inner wall of the trachea and the catheter of the trachea cannula cannot be effectively sealed. Meanwhile, an extension pipe is required to be externally connected with an air bag pressure measuring meter for sterile operation during pressure measurement, time and labor are consumed, and real-time monitoring is difficult to achieve even if the pressure of gas in the air bag is measured at regular time.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide the trachea cannula with the function of monitoring the pressure of the air bag, which solves the problems, the pressure measuring device displays the gas pressure in the air bag, and medical personnel can find and adjust the pressure of the air bag in time; and the single use by a single person can not cause cross infection.
In order to achieve the purpose, the invention provides the following technical scheme:
trachea cannula with monitoring gasbag pressure function, including main intubate, gasbag, gas tube and inflating device, the gasbag is located main intubate lower part perisporium, and inflating device passes through gas tube and gasbag intercommunication, still includes pressure measurement device, has the cavity in pressure measurement device's the casing, establishes the piston in the cavity, and casing roof is opened the gas inlet and is communicate gas tube and piston top cavity, and the pressure measurement post is connected to the piston diapire, and the casing is worn out to pressure measurement post bottom, is equipped with pressure scale interval sign on the pressure measurement post global.
The invention further improves the technical scheme that the circumference of the pressure measuring column is coated with different color zone coatings corresponding to the pressure scale values from bottom to top, the lower part is an insufficient pressure zone, the middle part is a proper pressure zone, and the upper part is an overproof pressure zone. Visual monitoring is facilitated.
The invention further improves the technical scheme that the pressure measuring device is communicated with the inflation tube through a three-way tube.
The invention further improves the technical scheme that a switch valve is arranged on an inflation tube at the front end of the inflating device. Effectively preventing air leakage.
The invention has the beneficial effects that:
the main intubation is inserted into a preset position in the trachea through the oral cavity and the nasal cavity, the switch valve on the inflation tube is opened, the inflating device conveys gas into the air bag through the inflation tube, meanwhile, the gas enters the cavity of the shell of the pressure measuring device, the piston descends under the action of air pressure, the pressure measuring column extends out of the shell, and the scale value mark of the surface pressure is exposed, so that whether the gas in the air bag is proper or not is indicated. If there is air leakage in the use, the pressure measuring column can retract into the shell, and medical personnel can check and timely adjust the pressure in the air bag, thereby playing the effect of real-time monitoring.

Detailed Description
As shown in fig. 1 and 2, the trachea cannula with the function of monitoring the pressure of the air bag comprises a main cannula 1, the air bag 2, an inflation tube 3, an inflation device 4 and a pressure measuring device 5, wherein the air bag 2 is positioned on the peripheral wall of the lower part of the main cannula 1, the inflation device 4 is communicated with the air bag 2 through the inflation tube 3, a switch valve 6 is arranged on the inflation tube 3 at the front end of the inflation device 4, a cavity 52 is arranged in a shell 51 of the pressure measuring device 5, a piston 53 is arranged in the cavity, an air inlet is formed in the top wall of the shell and is communicated with the inflation tube 3 and a cavity above the piston, the bottom wall of the piston 53 is connected with a pressure measuring column 54, the bottom end of the pressure measuring column 54 penetrates.
In order to facilitate visual monitoring, the circumferential surface of the pressure measuring column 54 is coated with the zoned coatings 56 of different colors corresponding to the pressure scale values from bottom to top, the lower part is an insufficient pressure area 561, the coatings are white, the middle part is a suitable pressure area 562, the coatings are green, the upper part is an excessive pressure area 563, and the coatings are red. The pressure of the air bag is proper within 25-35 cmH20, so that the boundary of the pressure proper area and the pressure deficient area is matched with 25 cmH20, and the boundary of the pressure proper area and the pressure exceeding area is matched with 35cmH 20. When the exposed coating of the pressure measuring column is white, air needs to be supplied to the environment when the green coating is exposed, and when the red coating is exposed during inflation, the pressure in the air bag is too high, and part of air in the air bag needs to be discharged. The medical staff can monitor in real time in the routine operation and patrol process.
The pressure measuring device 5 of the invention is communicated with the inflation tube through a three-way tube.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
