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 Multifunctional nasal pharyngeal canal, lead to through side nose cut outs along nasopharynx during use
Road is inserted, until oral area reaches patient's glottis opening.Including nasopharynx tube body 1 setting is connected with the tail end of nasopharynx tube body 1
The breathing interface 3 with threaded pipe of breathing machine Breathing Suppotion Interface Matching.It is provided for blocking near the breathing interface 3 and suffers from
The nasal obstruction body 4 in person side nostril.
When patient causes respiratory tract not smooth because of macroglossia, nasopharynx tube body 1 can push the tongue body of hypertrophy open, in maxilla and
A respiration channel is formed between tongue body, patient is smoothly breathed, releases the not smooth critical disease of respiratory tract.Open the respiration channel side
Mouth goes out patient nostril in patient's glottis oral area, opposite side.Now, under emergency situation, the breathing matching of interface 3 can be connected to and exhaled
Suction machine screwed pipe breathing interface one end, so as to implement mechanical ventilation.Gas leaks during in order to reduce mechanical ventilation, by body 4 of having a stuffy nose
Opposite side nostril is blocked in, prevents gas from largely being leaked through opposite side nasal cavity.It is loose when nasopharynx tube body 1 implements mechanical ventilation
Tongue body can play a part of sealing gap between oral cavity and pharyngolaryngeal cavity, reduce gas and largely leaked from oral cavity.But it should be noted
It is：Implementing the gentle road pressure of tidal volume during mechanical ventilation should not be excessive, and otherwise gas is easily accessible in patient's gastral cavity, may cause to vomit
Tell to backflow and inhale by mistake, cause adverse events.
As shown in Figures 2 and 3, the corresponding patient's choana cavity interior position of the nasopharynx tube body 1 sets fixation balloon 5,
And connect fixation balloon 5 and gas tube 51 is set in nasopharynx tube body 1, gas tube 51 is connected in the endpiece of nasopharynx tube body 1 and set
Outer gas tube 52, the outer tail end of gas tube 52 connection set pressure experience air bag 53, and connection pressure experience air bag 53 sets pressure valve
Inflation inlet 54.
The nasopharynx tube body 1 is inserted in patient's nasopharynx passage, patient choked because discomfort might have cough action, or vomiting
Action, with the action of this resistance, nasopharynx tube body 1 can slowly skid off nasal cavity cavity.In the corresponding patient's nose of nasopharynx tube body 1
Metapore cavity interior position sets fixation balloon 5, can be right by the gas tube 51 of connection, outer gas tube 52 and pressure valve inflation inlet 54
The fixation balloon 5 for the nasopharynx tube body 1 inserted in patient's nasopharynx passage is filled with gas, and the glutted volume of fixation balloon 5 is much big
In the aperture of nasal cavity choana, fixation can be played to nasopharynx tube body 1.And pressure experience air bag 53 connects with fixation balloon 5
Logical, pressure is identical, and by experiencing the pressure of pressure experience air bag 53, the gas pressure of fixation balloon 5 can be judged.Together
When, fixation balloon 5 can play plugging action after being filled with gas to the gap in around nasopharynx tube body 1 and oral cavity, further enhance
Nasopharynx tube body 1 implements seal during mechanical ventilation.
As shown in figure 3, siphunculus 2 in being buried in the tube wall of nasopharynx tube body 1, the interior head end of siphunculus 2 go out ductus nasopharyngeus sheet
Tube wall connection sets free pipe 21 on the inside of the head end of body 1.The free pipe 21 is located at the inner chamber of nasopharynx tube body 1 and the free head end of pipe 21
Some inner openings 20 are set to point to the head end of nasopharynx tube body 1.The interior tail end of siphunculus 2 goes out tube wall on the outside of the tail end of nasopharynx tube body 1 and connected
Inner connection tube 22 is set, mouth 23 is connected in the setting of the tail end of inner connection tube 22.The outside tube wall of mouth 23 and carbon dioxide are connected in described
Sample tube cavity matching.
The free pipe 21 is the quality body stronger compared with hard toughness, is preferably provided in the middle part of the inner chamber of nasopharynx tube body 1 and cuts
The centre position in face, the front end tube chamber of the free pipe 21, preferably parallel with the inner chamber of nasopharynx tube body 1, the inner opening 20
Point to the head end of nasopharynx tube body 1.In this way, when by it is interior connect mouth 23 to nasopharynx 1 intracavitary administration of tube body when, medicine can enter rapidly
Enter air flue；When it is interior connect mouth 23 and connect capnograph when, positioned at tube chamber center towards opening in the head end of nasopharynx tube body 1
Mouth 20 can gather patient expiration end gas sample rapidly, so as to be judged to patient respiratory state；When patient's autonomous respiration,
Also mouth 23 can be connected inside and connects oxygen hose, realize the oxygen uptake of patient airway deep, oxygen uptake excellent.
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.
In a word, the tail end of nasopharynx tube body 1 sets breathing interface 3, and lung ventilator is connected after blocking opposite side nasal cavity with nasal obstruction body 4
Can do Breathing Suppotion, fixation balloon 5, which is set, can play fixation, there is provided interior siphunculus 2 can be used for through the oxygen uptake of ductus nasopharyngeus inner chamber,
End expiratorycarbon dioxide is monitored, it is simple in construction, it is convenient to implement, securely and reliably.Its is simple in construction, and cost is cheap, user
Just, securely and reliably.
