Air duct capable of introducing oxygenTechnical Field
The utility model relates to the technical field of medical equipment, particularly, be an air vent that can lead to oxygen.
Background
In order to meet the desire of people for good life, various painless diagnosis and treatment technologies are widely developed in China in recent years. Such as painless gastrointestinal endoscopy, painless induced abortion, painless tooth extraction, medical plastic surgery and the like, most of the methods adopt intravenous anesthesia, and the anesthesia technology, method and requirements thereof are greatly different from those of most clinical surgical anesthesia. The 'general anesthesia operation' is characterized in that anesthetic drugs and muscle relaxing drugs are applied to completely inhibit the respiration of a patient, and the respiration function of the patient is guaranteed through 'trachea intubation', 'breath control' of an anesthesia machine and 'oxygen supply'. The intravenous anesthesia is mainly that the brain of a patient is in inhibition states of different degrees through a certain amount of anesthetic, the respiratory function is inhibited by different degrees at the same time, and the ventilation and oxygen supply of the patient are met by matching an airway with an oxygen tube clinically. For example, the medical and aesthetic surgical anesthesia of the face is mostly a long-time local anesthesia combined with intravenous anesthesia.
The nasopharyngeal airway is a flexible tube similar to a tracheal tube inserted from the nasal cavity of a human body to the pharyngeal cavity, and the length of the tube is generally from the nasal vestibule to the front of the glottis of the pharyngeal cavity. Through adjusting the inserted degree of depth, relieve pharyngeal cavity tissue or organ to the obstruction of glottis, the problem of tongue tenesmus for example to can attract the secretion of pharyngeal cavity through the lumen of nasopharynx air duct, just so the unobstructed of effectual guarantee upper respiratory tract provides the guarantee for improving the efficiency that pressurizes for oxygen.
The existing nasopharyngeal airway is generally additionally provided with a channel connected with an oxygen tube, but when the nasopharyngeal airway is used, the oxygen tube is over against the pharyngeal mucosa of a patient, and the input oxygen is continuously blown to the pharyngeal mucosa of the patient under the condition of long-term use, so that the pharyngeal mucosa of the patient is easily damaged. Accordingly, there is a need for an airway device that provides uniform delivery of oxygen to a patient and reduces damage to the patient's pharyngeal mucosa.
Disclosure of Invention
In view of this, the present invention provides an airway capable of ventilating oxygen, so as to ventilate oxygen more uniformly and reduce the damage to the pharyngeal mucosa of the user.
In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides an air duct that can lead to oxygen, including the air duct, be equipped with the oxygen therapy pipe that is used for oxygen therapy on the air duct, the oxygen therapy pipe is followed the air duct outer wall sets up, be equipped with the venthole that is used for reposition of redundant personnel oxygen air current pressure when leading to oxygen on the oxygen therapy pipe.
Furthermore, the outer wall of the air passage is provided with a groove matched with the outer wall of the oxygen tube in shape, and the oxygen tube is arranged in the groove.
Further, the air passage and the oxygen therapy pipe are integrally formed.
Furthermore, the end parts of the air passage and the oxygen conveying pipe are provided with flanges.
Further, the air outlet holes are formed in two sides of the oxygen conveying pipe.
Further, the oxygen therapy pipe extends to the middle lower part of the air passage.
Furthermore, an extension pipe is arranged at the inlet end of the oxygen therapy pipe.
Furthermore, a thickening joint is arranged on the extension pipe.
Further, when the nasal cavity air duct is used, a round angle is arranged on the tube wall of the port of the air duct in the nasal cavity.
Furthermore, the air passage and the oxygen therapy pipe are made of soft materials.
The beneficial effects of the utility model reside in that:
the outer wall of the air passage is provided with an oxygen tube for inputting oxygen, oxygen can be supplied to a user through the oxygen tube, and the part of the oxygen tube positioned in the nasal cavity is provided with an air outlet hole when the nasal cavity is used, so that the pressure of oxygen airflow can be shunted, and a part of oxygen is dispersed into the nasal cavity through the air outlet hole and then is conveyed to the pharyngeal portion of a patient, thereby reducing the damage to the mucous membrane of the pharyngeal portion of the patient;
in addition, this air channel device still is equipped with the fixing device who is used for fixed oxygen therapy pipe, can prevent that it from taking place the position change in the use, and this fixing device occupation space is little, can leave sufficient space in the air channel intracavity and supply gas to pass through.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
As shown in FIG. 1, for the present invention, the general schematic diagram of the embodiment of the ventilation channel for introducing oxygen comprises aventilation channel 1 and anoxygen tube 2, wherein theoxygen tube 2 is disposed along the outer wall of theventilation channel 1, and theoxygen tube 2 is provided with an air outlet 5 for shunting the pressure of oxygen flow when introducing oxygen. Can carry out the oxygen suppliment to the user throughoxygen therapy pipe 2, and the part thatoxygen therapy pipe 2 is located nasal cavity inside when using is provided with venthole 5, can shunt the pressure of oxygen air current for partly oxygen passes through 5 dispersions of venthole to the nasal cavity, carries to patient's pharynx again, reduces the damage to patient's pharynx mucosa. And theoxygen duct 2 of theair duct 1 and the connection mode are integrated into a longitudinal small upper part (the oxygen duct 2) and a large lower part (the air duct 1) which more conforms to the anatomical form of the narrow upper part and the wide lower part of the nasal cavity.
Optionally, as shown in fig. 2a, the outer wall of theairway 1 of this embodiment is provided with a groove 3 matching with the outer wall of theoxygen tube 2 in shape, and theoxygen tube 2 is disposed in the groove 3. Theoxygen tube 2 can be bonded in the groove 3 by means of bonding.
Alternatively, as shown in fig. 2b, in another embodiment theairway 1 and theoxygen tube 2 are integrally formed. This way, the ventilation space of theventilation duct 1 and theoxygen therapy tube 2 can be increased.
Further, the end portions of theair duct 1 and theoxygen duct 2 of the present embodiment are provided with flanges 4. The flange 4 is used for limiting theair duct 1 and theoxygen therapy tube 2 and preventing the air duct from falling into the nasal cavity when in use.
