Referring to fig. 3B, the nozzle edge of the inner tube 31 is connected to the nozzle edge of the outer tube 32 at both ends of the major axis by connecting pieces 7, and the nozzle edge of the inner tube 31 is connected to the nozzle edge of the outer tube 32 at both ends of the minor axis by connecting pieces 7. Referring to fig. 3C, the nozzle edge of the outer tube 32 is connected to the outer wall of the inner tube 31 at equal intervals in four directions by the connecting pieces 7.
The embodiment can be optimally designed as follows: the front end orifice (i.e. the first passage opening 42) of the inner tube 31 is a flat horn-shaped opening (see fig. 3B and 3C), so the design can increase the contact area of oral secretion, and the inner side wall of the horn-shaped opening also plays a role in guiding the flow of the first passage opening 42, thereby avoiding the oral secretion from blocking the first passage opening 42. Correspondingly, referring to fig. 3B, the front end orifice of the outer tube 32 is also a flat bell mouth, the orifice of the outer tube 32 is coaxial with the major axis and the minor axis of the orifice of the inner tube 31, the major axis of the orifice of the outer tube 32 is larger than the major axis of the orifice of the inner tube 31, and the minor axis of the orifice of the outer tube 32 is larger than the minor axis of the orifice of the inner tube 31, so that an annular thin orifice (i.e., a second passage orifice 52) is formed between the front end orifice of the outer tube 32 and the front end orifice of the inner tube 31, and the second passage orifice 52 is flush with the first passage orifice 42; alternatively, referring to fig. 3C, the outer tube 32 is shorter than the inner tube 31 and the second opening 52 is located rearward of the first opening 42 such that the flared outer sidewall of the inner tube 31 acts as a deflector for the second opening 52.
In this embodiment, the first interface 41 may be connected with an aspirator connection tube; the second interface 51 is connected with a three-way joint 6, and the three-way joint 6 can be simultaneously connected with an oxygen supply connecting pipe and a drug administration connecting pipe so as to simultaneously supply oxygen and administer drug; the three-way joint 6 can also be simultaneously connected with two oxygen supply connecting pipes to supply oxygen independently so as to improve the oxygen supply speed, or one oxygen supply connecting pipe is connected, and the other joint is plugged when not used; the three-way joint 6 can also be connected with a drug administration connecting pipe to independently administer drug.
A more preferred mode of use is: the second connector 51 is connected with the oxygen supply connecting pipe and the drug administration connecting pipe through the three-way connector 6, and oxygen supply and drug administration are realized simultaneously. Because the second opening 52 is an annular narrow opening, the medicine is ejected from the annular narrow opening under the driving of oxygen with certain pressure, and negative pressure is formed at the front end of the annular narrow opening, which is helpful for spraying the medicine to the glottis.
It will be understood by those skilled in the art that these examples or embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention, and that various equivalent modifications and changes may be made to the present invention without departing from the spirit of the present disclosure.
