specifically, as shown in fig. 1 and 2, when the mechanism is used, firstly, a filter screen 302 is fixedly connected to the bottom end inside an air suction pipe 301, and an activated carbon layer 303 is arranged at the top end of the filter screen 302, when the purification structure 3 sucks air to the outside, the air enters the air suction pipe 301 through holes inside the filter screen 302 and moves upwards rapidly, and most of impurities such as dust, particles and the like in the air are filtered through double purification of the activated carbon layer 303 and a nutrient solution sponge 304, so that the lung of a patient is prevented from being damaged due to turbid sucked air;
the fixing structure 6 comprises an air bag 601, an air pipe 602 and fixing grooves 603, the inner side wall of the air bag 601 is fixedly connected with one side of the outer side wall of the gas circulation pipe 5, the bottom end of one side of the air bag 601 is fixedly connected with the air pipe 602, the bottom end of the gas circulation pipe 5 is provided with the fixing grooves 603, the horizontal center line position of the air bag 601 is parallel to the gas circulation pipe 5, and the fixing grooves 603 are distributed at equal intervals at the bottom end of the gas circulation pipe 5;
specifically, as shown in fig. 1 and 3, when the mechanism is used, firstly, the air pipe 602 is fixedly connected to the bottom end of one side of the air bag 601, after the intubation tube is inserted into the trachea of the patient, the air bag 601 is rapidly expanded and enlarged by inflating from one end of the air pipe 602, at this time, the air bag 601 is blocked at the trachea of the patient, so that the breathing of the patient is circulated only through the intubation tube, and the phenomenon that the intubation tube shakes along with the breathing of the patient after being inserted into the trachea of the patient is prevented;
the backflow prevention structure 7 comprises a first limiting sleeve 701, a first hinged cover 702, a second limiting sleeve 703 and a second hinged cover 704, the outer side wall of the first limiting sleeve 701 is fixedly connected with the top end of the inner side wall of the purification structure 3, one side of the top end of the first limiting sleeve 701 is hinged with the first hinged cover 702, the inner side wall of the gas control pipe 2 is fixedly connected with the second limiting sleeve 703, the top end of one side of the second limiting sleeve 703 is hinged with the second hinged cover 704, the cross sectional area of the outer side wall of the first limiting sleeve 701 is identical to that of the inner side wall of the gas suction pipe 301, and a hinged structure is formed between the first limiting sleeve 701 and the inside of the first hinged cover 702;
specifically, as shown in fig. 1, 3 and 4, when using the mechanism, firstly, the outer side wall of the first position-limiting sleeve 701 is fixedly connected with the top end of the inner side wall of the purification structure 3, one side of the top end of the first position-limiting sleeve 701 is hinged with the first hinged cover 702, the medical staff squeezes the squeeze ball 1 with hands, so that the air in the squeeze ball 1 is forced to be delivered to the inside of the air control tube 2, because the first hinged cover 702 inside the purification structure 3 is tightly attached to the top end of the first limiting sleeve 701 under the influence of air pressure, air can not circulate, and because the second limiting sleeve 703 is connected with the second hinged cover 704 in a hinged mode, the second hinged cover 704 is slowly lifted under the influence of the air pressure, air in the gas control tube 2 can only circulate in the gas circulation tube 5 through the second limiting sleeve 703 and finally flow into the lung of a patient, so that the phenomenon that the patient breathes unsmoothly after using the intubation tube is avoided.
The working principle is as follows: when the utility model is used, firstly, when the intubation tube is needed to be used for passively breathing a patient, one end with a fixed structure 6 is inserted into the trachea of the patient through the oral cavity or the nasal cavity of the patient, then, the trachea is inflated through one end of the air pipe 602, so that air flows into the air bag 601 and rapidly expands to become large, the outer side wall of the air bag 601 which becomes large after the air bag 601 is inflated completely can be clung to the inner side wall of the trachea of the patient, so that the intubation tube is blocked at the trachea of the patient, the breathing of the patient can be circulated only through the intubation tube, meanwhile, the appearance of the air bag 601 is longer, and the area of the outer side wall of the air bag 601 can also become large correspondingly after the expansion and the enlargement of the air bag 601, so that the contact area of;
secondly, after the intubation tube is successfully inserted into the trachea of the patient and fixed, the medical staff squeezes the squeeze bulb 1 with hands, so that the air in the squeeze bulb 1 is forced to be delivered to the inside of the air control tube 2, because the first hinged cover 702 in the purifying structure 3 is tightly attached to the top end of the first stop collar 701 under the influence of the air pressure, the air cannot circulate, and because the second stop collar 703 is connected with the second hinged cover 704 in a hinged manner, the second hinged cover 704 is slowly lifted under the influence of the air pressure, so that the air in the air control tube 2 can only circulate to the air circulation tube 5 through the second stop collar 703 and finally gushes to the lung of the patient, so that the patient can inhale the air, when the patient inhales the air, the carbon dioxide can be automatically exhaled into the air circulation tube 5 and flows into the air control tube 2 through the air circulation tube 5, at the moment, the second hinged cover 704 is tightly closed again under the influence of the air pressure of the carbon dioxide, so that the carbon dioxide cannot, the exhaled carbon dioxide is exhausted from the inside of the intubation tube through the exhalation tube 4, so that the backflow of the carbon dioxide is avoided, then the hands which squeeze the squeeze ball 1 are released to enable the squeeze ball 1 to recover the shape, and air is inhaled from the outside into the inside of the squeeze ball 1 through the purification structure 3;
finally, after medical personnel loosened the hand of extrusion pressing ball 1, pressing ball 1 resumes original shape and through purification structure 3 outside inhaled air, the air passed through inside hole entering breathing pipe 301 of filter screen 302 and upwards removed fast this moment, dust and particulate matter in the air can be adsorbed by activated carbon layer 303 when air contact activated carbon layer 303, make the air tentatively filter, the air continues to go up the mountain and gets into inside nutrient solution sponge 304 subsequently, make the nutrient solution moisture of being of value to patient's lung breathing in the air absorption nutrient solution sponge 304, the air can get into pressing ball 1's inside through gas control pipe 2 afterwards, and extrude pressing ball 1 once more through medical personnel and flow into patient's lung, the passive work of breathing of this top trachea cannula is finally accomplished.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
