Abstract
The utility model relates to an oxygen uptake type ventilation pipe for nasopharynx, in particular to a pipe which is put into the upper part of gullet via nasal cavity to transport oxygen for patients. The ventilation pipe is characterized in that the pipe comprises a ventilation pipe, a blocking sheath chamber for the gullet, an oxygen transportation conduit and a monitoring conduit, wherein, the ventilation pipe is used as a main body pipe for the oxygen uptake type ventilation pipe used for nasopharynx, the front end of which is sealed into a conical blind end, and a plurality of small holes are distributed from the one third point at the front part of the ventilation pipe to the pipe periphery of the upper part of an air chamber; the oxygen transportation conduit and the monitoring conduit are arranged in the wall of the ventilation pipe, and the trend thereof accords to the trend of a vertical axis of the ventilation pipe. The ventilation pipe has the advantages that the conical blind end can insert conveniently to protect mucous membrane from being injured, the blocking sheath chamber for the gullet not only can fix the position of the pipe but also divide the gullet and the windpipe to prevent gullet back flow and reduce aspiration, and the special oxygen transportation pipe is designed to transport oxygen and suck sputum; the monitoring pipe can monitor breath frequency of the patients at any moment and the concentration of O2 and CO2 to increase security of the patients, and a plurality of side holes can effectively carry out ventilation function and reduce the defect of off-normal ventilation when the inclined opening of the front end of the traditional ventilation pipe used for the nasopharynx is stuck on the mucous membrane.
Description
Technical field
This utility model relates to the oxygen absorption type nasopharynx airway that a kind of medical per nasal is ventilated to patients accepting oxygen inhalation.
Background technology
When using traditional nasopharynx airway to give patient ventilating clinically, because narrow, the difference in length of the physiology of human body pars oralis pharyngis, make nasopharynx airway front end diagonal cut joint be attached on the mucosa easily or inserted that to take an advanced study into ventilation not smooth.And nasopharynx airway front end stimulates epiglottis and glottis, easily makes patient that anti-stream and mistake suction take place, and causes aspiration pneumonitis, also can bring out laryngospasm, threatens patient's life security.It is the monitoring of patients accepting oxygen inhalation and vital sign that tradition nasopharynx airway also is inconvenient to.
The utility model content
This utility model can prevent the generation of above rough sledding effectively, provide a kind of simple to operate, little to mucosa injury, prevent esophageal reflux, reduce the mistake suction, reduce traditional nasopharynx airway complication and can make things convenient for oxygen uptake and the oxygen absorption type nasopharynx airway of monitoring vital sign.
The technical scheme in the invention for solving the technical problem is:
A kind of per nasal is inserted the oxygen absorption type nasopharynx airway on esophagus top, it comprises: airway, esophagus shutoff cover capsule, oxygen delivery tube, monitoring tube, wherein airway is the main body pipe of this oxygen absorption type nasopharynx airway, length is about 16cm-28cm, has certain pliability and toughness, its front end seals tapered cecum, there are a plurality of side openings at preceding 1/3 place of airway to the air bag top in pipe week, the summation of its side opening cross-sectional area is greater than the cross-sectional area of airway, the airway rear end is mososeries, there is guide hole its side, oxygen delivery tube, monitoring tube and gas tube pass through this hole.Described esophagus shutoff cover capsule comprises air bag, gas tube, indication capsule and the check valve that is positioned at the airway front end.Described oxygen delivery tube and monitoring tube are parallel with the gas tube of cover capsule in the airway wall, and consistent with the longitudinal axis trend of airway, oxygen delivery tube and the monitoring tube airway inwall above air bag is provided with opening.Diameter and this oxygen absorption type airway of length according to the airway body can be divided into different size.
The taper cecum is convenient to be inserted described oxygen absorption type nasopharynx airway owing to being provided with, little to mucosa injury;
Described oxygen absorption type nasopharynx airway is because the airway rear end is mososeries, and there is guide hole its side, and its rear end of conduit is difficult for and the nose friction, in case cause the skin damage of nose week.Oxygen delivery tube, monitoring tube and gas tube can pass through guide hole, are fixed in the homonymy cheek, put just doctor's operation.
But thereby described oxygen absorption type nasopharynx airway is owing to be provided with not only A/C position but also esophagus and air flue can be separated and prevent esophageal reflux, reduce the mistake suction of esophagus shutoff cover capsule;
Described oxygen absorption type nasopharynx airway is owing to be provided with taper cecum and air bag simultaneously, and the air bag of unaerated is attached to the taper cecum place of airway when inserting, and does not influence the visual field when inserting;
Described oxygen absorption type nasopharynx airway has realized that oxygen supply simultaneously also can inhale expectorant owing to be provided with oxygen delivery tube;
Described oxygen absorption type nasopharynx airway is owing to be provided with respiratory frequency, the O that monitoring tube can be monitored patient at any time
2Concentration and CO
2Concentration has strengthened patient safety.
Described oxygen absorption type nasopharynx airway is owing to be provided with a plurality of side openings and more effectively realize ventilatory function, reduces traditional nasopharynx airway front end diagonal cut joint and is close to the drawback that the air flue mucosa can't normal ventilation.
