Description
Technical field
The utility model belongs to technical field of medical equipment, is related to a kind of anesthetic tube, and in particular to one kind can retain certainly
The inhalation anesthesia conduit of main breathing.
Background technology
Inhalation anesthetic enters in vivo and excluded through pulmonary ventilation, and the regulation of its depth of anesthesia is compared with other intravenous anesthetics more
Easily.Inhalation anesthetic such as sevoflurane, there is good analgesia and anesthetic effect, and it is light to respiration inhibition, it can retain independently
The operation of body surface and four limbs, such as TURP, uterus conization are completed in the case of breathing；In auxiliary intraspinal tube
When anesthesia and nerve block, the anesthesia of laparoscopic cholecystectomy, intestinal canal tumour resection etc. can be completed.
Currently used inhalation anesthesia instrument mainly has：Mask, laryngeal mask and trachea cannula.When the wake-up fiber crops of row operations on cranium and brain
When liquor-saturated, Upper respiratory tract obstruction can be occurred because of glossoptosis etc. by implementing inhalation anesthesia using mask, and use laryngeal mask or trachea cannula then
Patient's glottis, which can be taken, makes it not speak, and can not realize requirement of the patient with operative doctor dialogue in operation；In addition, it is expert at
During the minor operation of oral cavity, if operative site will be taken by implementing inhalation anesthesia with mask or laryngeal mask, it can be used if with trachea cannula
Muscle relaxant and patient's autonomous respiration can not be retained；The air flue instrument of the non-trachea cannula of intranasal only has nasopharyngeal air duct at present,
But if inhalation anesthesia directly implemented using nasopharyngeal air duct, can patient's mouth and nose it is unclosed, cause the anesthesia gas of patient's exhalation
Know from experience and leak into operating room through mouth and nose, pollute, and can not easily and accurately monitor end-tidal CO2With anesthetic gases
Concentration.Therefore clinically need one kind to retain autonomous respiration at present and can prevent waste gas of anesthesia from leaking and keep the upper respiratory tract to lead to
Freely, accurate measurements end-tidal CO is facilitated2With the inhalation anesthesia conduit of anesthesia gas concentration.
Utility model content
The purpose of this utility model is to provide a kind of anesthetic tube, and the specific one kind that provides can retain autonomous respiration and can keep
The upper respiratory tract is unobstructed and prevents the inhalation anesthesia conduit of waste gas of anesthesia leakage.
The purpose of this utility model is achieved by the following technical solution：A kind of anesthetic tube, including nasal cavity
Insertion end and equipment connection end, the anesthetic tube are provided with air inlet pipe and negative-pressure suction pipe., will during using the anesthetic tube
The lung ventilator connector and vacuum extractor connector of equipment connection end are connected respectively on relevant device, by anesthetic tube nasal cavity
Insertion end is inserted into bottleneck throat (on glottis at 1-2 centimetres) through patient's nasal cavity, will not take the positions such as oral cavity or cranium brain, and anaesthetize
The nasal cavity insertion end port of conduit is located on glottis and without glottis, can allow patient anesthesia subtract it is shallow after speak.Sucked
During anesthesia, patient can retain autonomous respiration, suck the anesthetic gases and oxygen imported by Anesthesia machine, the CO of exhalation2
Taken away with waste gas of anesthesia through negative-pressure suction pipe, such anesthetic gases, which would not leak into, pollutes environment in air；This cavitas oris externa point
Secretion or blood can also be taken away by negative-pressure suction pipe without blocking anesthetic tube mouth or preventing it from entering tracheae.As preferred
Technical scheme, the position of opening of negative-pressure suction pipe are arranged on anesthetic tube on the outer wall of insertion end port；The air inlet pipe
It is arranged in the tube chamber of negative-pressure suction pipe, or negative-pressure suction pipe is arranged on the outer wall of air inlet pipe.
End-tidal gas concentration monitoring device connecting tube, preferably described end-tidal gas are additionally provided with the anesthetic tube
Concentration monitoring device connecting tube is arranged in the tube chamber of negative-pressure suction pipe, more preferably described end-tidal gas concentration monitoring device connection
Pipe is arranged in negative-pressure suction pipe tube chamber on the outer wall of air inlet pipe.When carrying out inhalation anesthesia using the anesthetic tube, Huan Zhehu
The CO gone out2End-tidal gas concentration monitoring device connecting tube, which is run past, with anesthetic gases reaches monitor.
Air bag and balloon catheter are additionally provided with the anesthetic tube, air bag is arranged on anesthetic tube close to insertion end port
Outer wall on, balloon catheter is connected on air bag.Preferably air bag is annular, and the balloon catheter is arranged on negative-pressure suction pipe
On inwall.The effect of air bag mainly plays a supportive role, and inflates and is vented to air bag by balloon catheter, can adjust air bag
Size prevents opening on the pharyngeals such as the tongue of tenesmus obstruction air inlet tube opening and negative-pressure suction pipe to adapt to different patients
Hole, it can in addition contain stop that oral secretion or blood etc. flow into tracheae.
The beneficial effects of the utility model are：Relative to prior art, the utility model can reach following effect：1st, make
During with the execution of instrument inhalation anesthesia, patient's autonomous respiration can be retained without trachea cannula or laryngeal mask；2nd, row oral cavity
Or the position such as cranium brain operation when, will not take operative site using the execution of instrument inhalation anesthesia；3rd, using the execution of instrument
Without glottis during awaking anaesthesia, can allow patient anesthesia subtract it is shallow after speak；Will not when the 4th, using the execution of instrument inhalation anesthesia
Inhalation anesthetic waste gas is caused to be leaked to surgical environments；Can easily and accurately it be monitored when the 5th, using the execution of instrument inhalation anesthesia
End-tidal CO2With the concentration of anesthetic gases；When the 6th, using the execution of instrument inhalation anesthesia upper respiratory tract can be kept unobstructed, without
Insert oropharynx or nasopharyngeal air duct.
