Embodiment
With reference to specific drawings and examples, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, a kind of multi-functional nasopharyngeal air duct, through side nose cut outs along nose during use
Pharynx passage is inserted, until oral area reaches patient's glottis opening.Including nasopharyngeal air duct body 1 and it is embedded in nasopharyngeal air duct sheet
Interior siphunculus 2 in the tube wall of body 1, the interior head end of siphunculus 2 go out tube wall connection on the inside of the head end of nasopharyngeal air duct body 1 and set free pipe
21.The free pipe 21 is located at the inner chamber of nasopharyngeal air duct body 1 and the free head end of pipe 21 sets some inner openings 20 to point to nasopharynx
The head end of airway body 1.The interior tail end of siphunculus 2 goes out tube wall connection on the outside of the tail end of nasopharyngeal air duct body 1 and sets inner connection tube 22, interior
The tail end of connecting tube 22 connects mouth 23 in setting.
The free pipe 21 is the quality body stronger compared with hard toughness, is preferably provided in the inner chamber of nasopharyngeal air duct body 1
The centre position in portion section, the front end tube chamber of the free pipe 21 is preferably parallel with the inner chamber of nasopharyngeal air duct body 1, described
Inner opening 20 points to the head end of nasopharyngeal air duct body 1.In this way, when by it is interior connect mouth 23 to the intracavitary of nasopharyngeal air duct body 1 to
During medicine, medicine can quickly enter air flue；When it is interior connect mouth 23 and connect capnograph when, positioned at tube chamber center towards nasopharynx
The inner opening 20 of the head end of airway body 1 can gather patient expiration end gas sample rapidly, so as to be made to patient respiratory state
Judge；When patient's autonomous respiration, mouth 23 can be also connected inside and connects oxygen hose, realizes the oxygen uptake of patient airway deep, oxygen uptake effect
Fruit is splendid.
The outside tube wall of mouth 23 is connected in described to match with carbon dioxide sampling tube cavity.It is easy to connect carbon dioxide sampling pipe
Complete end-expiratory carbon dioxide monitoring.When needing oxygen uptake, Oxygen tube can be also engaged in connect mouth 23, you can conveniently realize gas
The oxygen uptake of road deep, oxygen uptake effect are good.
It is necessary, of course, to, the switch that can close inner connection tube 22 is set in inner connection tube 22, or connects the interface of mouth 23 inside
The cock body or lid that mouth 23 is connected in sealing nearby are set.When without using interior siphunculus 2, can close in siphunculus 2, to a certain degree
On be avoided that tracheal catheter body 1 ventilate when gas leakage.
As shown in Figures 2 and 3, the tail end of nasopharyngeal air duct body 1 connection sets breathing interface 3, with respirator screw
Pipe Breathing Suppotion Interface Matching.And it is provided for blocking the nasal obstruction body 4 in patient side nostril near nasopharyngeal air duct body 1.
When patient because tongue body excessively it is loose block the upper respiratory tract and cause breathing to be obstructed after, through side nostril by the utility model
Glottis mouth is inserted into, respirator screw pipeline can be connected in the breathing interface 3 of the tail end of nasopharyngeal air duct body 1, implement breathing machinery
Ventilation, nasopharyngeal air duct body 1 play a part of breather line.Now, loose tongue body, which serves, blocks oral cavity position crack
Effect, be avoided that gas direct oral cavity portion leak.But breathing path seal now is very poor, because pharyngolaryngeal cavity and opposite side nose
Hole connects, and gas can quickly escape through opposite side nostril.It is artificial to establish if nasal obstruction body 4 is blocked at opposite side nose cut outs
Breathing path seal greatly increase, the effect of mechanical ventilation will be more preferable.But it should be noted that：Implement moisture during mechanical ventilation
Amount and airway pressure are unsuitable excessive, and otherwise gas is easily accessible in patient's gastral cavity, and vomiting may be caused to backflow by mistake and inhaled, cause bad thing
Part.
As shown in figure 3, the corresponding patient's choana cavity interior position of nasopharyngeal air duct body 1 sets fixation balloon 5, and
Connect fixation balloon 5 and gas tube 51 is set in nasopharyngeal air duct body 1, gas tube 51 connects in the endpiece of nasopharyngeal air duct body 1
Logical to set outer gas tube 52, the outer tail end of gas tube 52 connection sets pressure experience air bag 53, and connection pressure experience air bag 53 is set
Pressure valve inflation inlet 54.
The nasopharyngeal air duct body 1 is inserted in patient's nasopharynx passage, patient choked because discomfort might have cough action, or
Vomiting acts, and with the action of this resistance, nasopharyngeal air duct body 1 can slowly skid off nasal cavity cavity.In nasopharyngeal air duct sheet
The corresponding patient's choana cavity interior position of body 1 sets fixation balloon 5, passes through the gas tube 51, outer gas tube 52 and pressure of connection
Valve inflation inlet 54 can be filled with gas to the fixation balloon 5 for inserting the nasopharyngeal air duct body 1 in patient's nasopharynx passage, and glutted consolidates
Determine the aperture that the volume of air bag 5 is far longer than nasal cavity choana, fixation can be played to nasopharyngeal air duct body 1.And feeling of stress
Connected by air bag 53 with fixation balloon 5, pressure is identical, can be to fixation balloon 5 by experiencing the pressure of pressure experience air bag 53
Gas pressure judges.Meanwhile fixation balloon 5 be filled with gas after can be to the gap in around nasopharyngeal air duct body 1 and oral cavity
Plugging action is played, further enhances seal when nasopharyngeal air duct body 1 implements mechanical ventilation.
In a word, the utility model can be inhaled by setting interior siphunculus 2 in nasopharyngeal air duct body 1 through nasopharyngeal air duct inner chamber
Oxygen, capnograph monitoring patient expiration end gas concentration lwevel can be connected；Set and exhale in the afterbody of nasopharyngeal air duct body 1
Suction mouth 3, lung ventilator can be connected, coordinate nasal obstruction body 4 to block other side nostril, Breathing Suppotion can be implemented to patient；By solid
Fixation can be played by determining air bag 5, while can also strengthen the seal of mechanical ventilation.Its is simple in construction, and cost is cheap, user
Just, securely and reliably.
