Detailed Description
As shown in fig. 1-5, the airway humidifying device for intubation is mainly applied to humidification heating of an artificial airway to solve the problems of water loss and dryness of the artificial airway and the heating of inhaled gas. Compared with the traditional heating humidifier, the electric heating humidifier has the advantages that electric heating is omitted, the overall structure is simpler, and the use is more convenient. In particular, the invention comprises a humidifier for generating heated humidified gas, which mainly comprises two major parts of a vortex tube 1 and a venturi atomizing tube 2. The vortex tube 1 can be used for separating cold and hot gases under the condition of no power consumption, and can be matched with a portable small gas tank for use. The venturi atomizing tube 2 is connected with a liquid storage tank for containing humidifying liquid, and the venturi atomizing tube is used for atomizing the humidifying liquid through a venturi effect.
As shown in fig. 1, the vortex tube 1 of the present invention comprises a first tube body 3, wherein the middle section of the first tube body 3 is an air inlet section 4, two ends of the first tube body 3 form a hot air end 5 and a cold air end 6, the air inlet section 4 is provided with an air inlet 7 communicated with the air inlet section 4 along the tangential direction of the air inlet section 4, and the air inlet 7 is communicated with a high-pressure air source. The hot air end 5 of the first pipe body 3 is provided with a reflecting cone 8, the hot air end 5 is communicated with the head end of the Venturi atomization pipe 2, the tail end of the Venturi atomization pipe 2 is communicated with an artificial air passage, and the middle section of the Venturi atomization pipe 2 is communicated with a liquid storage tank 10 through a liquid conveying pipe 9. When the vortex tube 1 is applied, high-pressure air flow enters from the air inlet 7 and spirally moves towards the hot air end 5 in the first tube body 3, high-temperature air overflows from between the reflecting cone 8 and the wall of the hot air end 5, and low-temperature air flows back under the action of the reflecting cone 8 and flows out from the cold air end 6.
Of course, in order to facilitate temperature adjustment, the reflecting cone 8 of the present invention may take a form capable of being adjusted in the left-right direction, and more specific implementation forms thereof are shown in fig. 4, and one of the simpler and feasible ways may be: the hot air end 5 of the first pipe body 3 is provided with an adjusting cylinder 18, and the adjusting cylinder 18 is sleeved outside the hot air end 5 and is in threaded connection with the hot air end 5. The reflecting cone 8 is installed at the center of the adjusting cylinder 18 through a bracket 19, and the small-sized end of the reflecting cone 8 faces the inside of the first pipe body 3. Through rotating the adjusting cylinder 18, the adjusting cylinder 18 drives the reflecting cone 8 to move in the moving process, so that the adjustment of the flow diameter of the overflow hole of the hot air end 5 is realized, and the adjustment of the air outlet temperature of the hot air end 5 can be realized. Since the adjusting cylinder 18 is a rotating component, in order to be connected with the venturi atomizing tube 2, one end, far away from the first tube body 3, of the adjusting cylinder 18 is provided with a rotary joint 20, and the rotary joint 20 is communicated with the head end of the venturi atomizing tube 2 through a telescopic bellows 21.
In the use process of the invention, a high-pressure air source is communicated with the vortex tube 1, and compressed air can be directly separated to form cold air and hot air by the characteristic of the vortex tube 1 and blown out from the cold air end 6 and the hot air end 5 respectively. The hot air flow blown out from the hot air end 5 enters the Venturi atomization tube 2, venturi effect can be achieved directly on Venturi atomization of the humidifying liquid, and meanwhile, the atomized air flow is the hot air flow, so that the air flow has certain evaporation atomization characteristics, and the overall atomization effect of the Venturi atomizer 2 can be improved. Meanwhile, the comprehensively mixed humidified gas has a warm characteristic, and an electric heating component is not required to be independently configured. Therefore, the invention can realize the synchronous conversion of damp and heat while simplifying the existing structure, and is very convenient to use. And the method can realize electroless operation, is very suitable for special occasions such as field first aid, battlefield first aid and the like, and has excellent application prospect.
In order to further improve the atomization performance of the present invention and enable the atomized air flow to be better uniformly distributed in the tube cavity, the venturi atomization tube 2 comprises a second tube body 11, and the second tube body 11 sequentially comprises a convergence section 12, a mixing section 13 and a diffusion section 14 along the direction away from the vortex tube 1. An annular cavity 15 is arranged in the pipe wall of the mixing section 13, an outer hole 16 is arranged in the pipe wall at the outer side of one end of the annular cavity 15, and the annular cavity is communicated with the infusion pipe 9 through the outer hole 16. A plurality of inner holes 17 are uniformly arranged in the pipe wall at the inner side of the other end of the annular cavity 15, and are communicated with the inside of the mixing section 13 through the inner holes 17. In this way, the hot air flow separated by the vortex tube 1 is accelerated by the convergence section 12 and flows at a high speed in the mixing section 13, so that the humidifying liquid in the annular cavity 15 is pumped into the mixing section 13 from the inner hole 17, atomization is realized, and finally uniform diffusion and ejection from the diffusion section 14 are realized. For the mixing effect of the humidifying liquid and the air flow, so as to realize efficient atomization, the inner end of the inner side hole 17 is communicated with the inside of the mixing section 13 along the tangential direction of the inner cavity of the mixing section 13. Generally, at least four inner holes 17 are arranged on the mixing section 13 to ensure uniform mixing in all directions.
Regarding the specific combination of the venturi atomizing tube 2 and the artificial airway, the invention can adopt the following modes: the tail end of the venturi atomizing tube 2 is directly communicated with the artificial airway through a humidifying interface 23 arranged on the side wall of the artificial airway, and in this case, the humidifying interface 23 is usually a Y-shaped tube interface which is directly arranged on the side surface of the artificial airway.
However, in order to further improve the performance of the present invention, it may be better to provide a connector at the tail end of the venturi atomizing tube 2, as shown in fig. 1 and 5, and to connect the connector to the artificial airway. The connector comprises a main pipe 22, wherein the upper end of the main pipe 22 is connected with a breathing machine air pipe, and the lower end of the main pipe 22 is connected with an artificial air passage. The side wall of the upper section of the main pipe 22 is provided with a humidifying interface 23 which is inclined upwards, and the humidifying interface 23 is connected with the tail end of the Venturi atomization tube 2. The lower main pipe 22 can be in a separated structure with the artificial airway, so that the whole assembly, disassembly and adaptation are convenient.
Of course, the invention can realize humidification of the artificial airway from the aspect of inhaling gas through the design, and basically works through active heating and humidification, but in order to realize temporary utilization of damp and heat in the exhaled gas, the invention can also be better. As shown in fig. 5, a moisturizing can 24 is provided on the outer side of the lower section of the main pipe 22, and an exhale port 25 is provided on the top of the moisturizing can 24. A side hole 26 communicated with the moisturizing shell 24 is formed in a section of main pipe 22 positioned at the upper inner part of the moisturizing shell 24, absorbent cotton 27 is arranged at the side hole 26, and the lower end of the absorbent cotton 27 extends to the bottom of the moisturizing shell 24.
In this case, the separation of the inhalation airway and the exhalation airway is actually performed, the inhalation airway is the main tube 22, and a plurality of blocking flaps 28 inclined obliquely downward are staggered in a section of the main tube 22 above the side hole 26, so that the blocking flaps 28 can block the exhaled air from being directly exhausted. And the exhalation airway is the lower section of main tube 22, side aperture 26, moisturizing shell 24 and exhalation port 25. When the exhaled air is blocked, it enters the moisturizing housing 24 from the side aperture 26 and finally exits through the exhalation port 25. The moisture absorbing cotton 27 can intercept and temporarily store the moisture in the exhaled air when the exhaled air passes through the side hole 26. When the sucked air passes through, a part of damp and heat can be wrapped and clamped on the absorbent cotton 27 and mixed into the artificial airway, and finally, the passive humidification and heating are realized.
Meanwhile, the excessive moisture in the expired air can be temporarily stored at the bottom of the moisture-preserving shell 24, and when the humidity of the inspired air is too low, the inspired air is absorbed to the side holes 26 by the moisture-absorbing cotton 27 at any time in a capillary mode, so that wet exchange is formed. Of course, the present invention may also achieve entrapment by increasing the condensation of the exhaled gas within the humidity chamber 24 in order to achieve maximum entrapment of moisture in the exhaled gas. For this purpose, the lower section of the moisturizing shell 24 may be in an inverted cone shape, and a condensation cavity 29 is disposed in the side wall of the upper section of the moisturizing shell 24, and the condensation cavity 29 is communicated with the cold air end 6 of the first tube body 3 through a shunt tube 30. Part of cold air flow discharged from the cold end of the vortex tube 1 can enter the condensation cavity 29 through the shunt tube 30, and after the expired air passes through the hygroscopic cotton 27, the condensation cavity 29 can perform certain heat exchange, so that moisture is condensed to the maximum extent, and moisture loss is avoided. Of course, since the cold air for condensation in the condensation chamber 29 is used only to promote condensation, its overall split should be appropriate to avoid low-temperature interference of the suction gas by the excessive cold air.
