Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a bronchial cannula with a suction function and an exhaust bag.
Background
Thoracic surgery requires that the anesthesiologist be able to stop the ventilation and collapse of the operative lung to protect the non-operative lung from blood, tumors, or infectious material and maintain the non-operative lung in ventilation. Without lung isolation and single lung ventilation techniques, thoracic surgery is quite dangerous. Ventilation is generally realized by a bronchial cannula of an air bag during operation, the air bag is fixed and closed, air leakage is prevented, the supply of tidal volume is ensured, and secretion and gastric content in the oropharynx part are prevented from being sucked by mistake after reflux; however, when secretion appears above the air sac, it is difficult to discharge the secretion out of the body in time.
SUMMERY OF THE UTILITY MODEL
The invention provides a bronchial cannula with a suction function and an exhaust bag, which can effectively solve the problems.
The invention is realized by the following steps:
the utility model provides a and exhaust bag trachea cannula with suction function, include trachea cannula and set up side by side in the big gasbag of first big gasbag and the second of trachea cannula outer wall, first big gasbag with the big gasbag of second is aerifyd the chamber respectively with first and is said and the second and aerify the chamber and say and be connected, first big gasbag is close to second big gasbag one side is provided with first suction hole, the big gasbag of second is kept away from first big gasbag one side is provided with the second and sucks the hole, first suction hole with the second sucks the hole and passes through trachea cannula inner wall communicates with each other, just first suction hole with the second sucks the hole and is said and suck the hole chamber and say and be connected.
As a further improvement, the front end of the bronchial cannula is connected with the first cavity channel and the second cavity channel, and the outer wall of the rear end of the bronchial cannula is also provided with a small air bag which is connected with the third inflation cavity channel.
As a further improvement, the first large air bag, the second large air bag and the small air bag are respectively provided with a first inflation port, a second inflation port and a third inflation hole.
As a further improvement, sealing valves are arranged at the upper end parts of the first inflation cavity channel, the second inflation cavity channel and the third inflation cavity channel.
The invention has the beneficial effects that: when the bronchus cannula with the suction function and the exhaust bag is used in an operation, the first big air bag and the second big air bag which are arranged side by side are alternately inflated, so that the condition that local pressure is excessive due to the fact that one air bag is intensively inflated for a long time, the blood circulation of the bronchus in the human body is insufficient, and the nursing risk is increased; the first suction hole and the second suction hole are respectively arranged beside the first big air bag and the second big air bag, and when secretion appears above the air bags, the secretion or liquid is sucked out of the body through the first suction hole or the second suction hole in time, so that the phenomenon that the secretion or liquid flows into the lung of a patient to cause the lung function reduction or the lung infection is avoided.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
Referring to fig. 1 to 2, a bronchial cannula with a suction function and an exhaust bag comprises a bronchial cannula 1, and a first big air bag 2 and a second big air bag 3 which are arranged on the outer wall of the bronchial cannula 1 side by side, wherein the first big air bag 2 and the second big air bag 3 are respectively connected with a first inflation channel 22 and a second inflation channel 32, a first suction hole 51 is arranged on one side of the first big air bag 2 close to the second big air bag 3, a second suction hole 52 is arranged on one side of the second big air bag 3 far from the first big air bag 2, the first suction hole 51 and the second suction hole 52 are communicated through the inner wall of the bronchial cannula 1, and the first suction hole 51 and the second suction hole 52 are connected with a suction hole channel 50.
