Abstract
The utility model discloses a laryngeal mask for upper gastrointestinal endoscopy, which comprises an air inflation bag, an endoscopic pipeline and a breathing pipeline. The endoscopic pipeline and the breathing pipeline are respectively connected with the air inflation bag. An air inflation pipe is connected onto the air inflation bag, a one-way valve is connected onto the air inflation pipe, the endoscopic pipeline and the breathing pipeline are arranged independently from each other, an upper end of the endoscopic pipeline is an outer port of an endoscope, a lower section of the endoscopic pipeline is arranged at the bottom of the air inflation bag, an inner port of the endoscope is arranged at the lower end of the air inflation bag, an outer diameter of the outer port of the endoscope is 1.5 cm, and an inner diameter of the outer port of the endoscope is 1.2 cm. An inner diameter of an inner port 7 of the endoscope is 1.2 cm. On the basis of a traditional laryngeal mask, the diameter of the endoscopic pipeline is enlarged, the upper gastrointestinal endoscopy can be guaranteed to be conducted smoothly, patients can have sufficient breath in a narcosis state, and if anesthesia accidents happen to the patients, rescue can be conducted fast.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of superior gastrointestinal endoscopy type laryngeal mask specifically.
Background technology
Traditional painless superior gastrointestinal endoscopy is at first implemented anesthesia to the patient, inserts digestive endoscope after the patient is sleeping.All general anesthesias all cause respiration inhibition in various degree to the patient at present, therefore under this narcotism, cause patient's hypoventilation easily, and the presence of oxygen saturation descends, and anesthetic accident takes place easily.And clinically in case anesthetic accident takes place; Need pull out superior gastrointestinal endoscope earlier and can implement comprehensive rescue the patient; Will expend many rescue times like this; Can't ventilate timely and effectively is the greatest problem that faces in the whole checking process, especially for the patient of cardio-pulmonary function difference, has potential great risk.In order to guarantee that the patient has enough pulmonary ventilation; Implementing the laggard circulation of qi promoting cannula of general anesthesia to the patient; But superior gastrointestinal endoscopy and tracheal intubation are co-located in a passage; Under this situation, the scope conduit is inserted on the next door of endotracheal tube more just may cause the upper digestive tract damage because of volumetrical problem, so carry out tracheal intubation inspection meeting the patient is caused unnecessary damage even increases financial burden.In sum, traditional painless superior gastrointestinal endoscopy has following shortcoming: 1. stimulate upper respiratory tract to cause laryngospasm easily; 2. cause hypoventilation easily, cause patient's anoxia.3. the possibility that causes mistake to be inhaled is arranged.4. rescue and expend time in.
Present superior gastrointestinal endoscopy of the prior art is that the patient is implemented anesthesia, keeps patient's autonomous respiration, adopts ultrashort effect intravenous anesthetic to anaesthetize, and guarantees that the patient can in time revive after inspection finishes.In order to reduce the misery of patient's tracheal intubation; The part patient adopts and to insert laryngeal mask and ventilate clinically; Can eliminate the wound of tracheal intubation to the patient; Though but laryngeal mask collar extension of the prior art has mutual isolated ventilation interface and thinner stomach tube interface, the stomach tube interface is too thin, can't insert scope.Superior gastrointestinal endoscopy is important inspection means of digestive tract disease diagnosis at present; Be to obtain pathological tissues the best way and means; The quantity that each hospital carries out superior gastrointestinal endoscopy has the trend that increases year by year; How can provide a kind of and not only can guarantee enough pulmonary ventilation, and the superior gastrointestinal endoscopy type laryngeal mask that gastroscopy and assisted respiartion can be carried out simultaneously becomes the urgent demand of people.
The utility model content
This utility model provides a kind of and not only can guarantee enough pulmonary ventilation in order to overcome the deficiency that prior art exists, and gastroscopy and the assisted respiartion superior gastrointestinal endoscopy type laryngeal mask that can carry out simultaneously.
This utility model is realized through following technical scheme: a kind of superior gastrointestinal endoscopy type laryngeal mask, comprise a gas cell, endoscopy pipeline and corrugated hose, and the endoscopy pipeline is connected with gas cell respectively with corrugated hose; On gas cell, be connected with a gas tube; Be connected with a check valve on the gas tube, the separate setting of endoscopy pipeline and corrugated hose, the upper end of endoscopy pipeline is the endoscopy collar extension; The hypomere of endoscopy pipeline is arranged at the bottom of gas cell; The endoscopy internal orifice is positioned at the lower end of gas cell, and the external diameter of endoscopy collar extension is 1.5cm, and internal diameter is 1.2cm; The internal diameter of endoscopy internal orifice 7 is 1.2cm.
The external diameter of said corrugated hose is 1.5cm, and internal diameter is 0.65cm.
The superior gastrointestinal endoscopy type laryngeal mask of this utility model is disposable plasticity laryngeal mask, meets the dissect physiology curve at human body laryngopharynx position,
The beneficial effect of this utility model is: this utility model enlarges the straight warp of endoscopy pipeline on the basis of conventional laryngeal mask; Can either guarantee carrying out smoothly of superior gastrointestinal endoscopy; Can guarantee that again the patient has enough ventilations in narcotism; And, need not pull out scope and just can drop into rescue rapidly in case anesthetic accident takes place.Independently the superior gastrointestinal endoscopy pipeline separates with corrugated hose, can significantly reduce the generation of reflux erroneous aspiration, and makes things convenient for inserting and locating of laryngeal mask, inserts simple.Gas cell can also be strengthened the sealing to laryngopharynx portion, and the laryngeal mask good airproof performance also can guarantee effective ventilation when long-time endoscopy.If this utility model is popularized, then can reduce the risk of patient in checking process greatly, improve safety coefficient, reduce the incidence rate that mistake is inhaled greatly.Laryngeal mask airway of this utility model and digestive tract are isolated, and guarantee enough pulmonary ventilation, and the laryngeal mask outer end connects respirator or breathing bag, can carry out assisted respiartion, makes gastroscopy and assisted respiartion to carry out simultaneously.
Description of drawings
Fig. 1 is the perspective view of this utility model superior gastrointestinal endoscopy type laryngeal mask;
Among the figure: 1. endoscopy pipeline; 2. corrugated hose; 3. gas cell; 4. gas tube; 5. check valve; 6. endoscopy collar extension; 7. endoscopy internal orifice.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in detail.
As shown in Figure 1, a kind of superior gastrointestinal endoscopy type laryngeal mask comprises a gas cell 3, endoscopy pipeline 1 and corrugated hose 2; Endoscopy pipeline 1 is connected with gas cell 3 respectively with corrugated hose 2, on gas cell 3, is connected with a gas tube 4, is connected with a check valve 5 on the said gas tube 4; Endoscopy pipeline 1 and corrugated hose 2 separate settings; The upper end of endoscopy pipeline 1 is an endoscopy collar extension 6, and the hypomere of endoscopy pipeline 1 is arranged at the bottom of gas cell 3, and endoscopy internal orifice 7 is positioned at the lower end of gas cell 3; The external diameter of endoscopy collar extension 6 is 1.5cm, and internal diameter is 1.2cm; The internal diameter of endoscopy internal orifice 7 is 1.2cm, and the external diameter of said corrugated hose 2 is 1.5cm, and internal diameter is 0.65cm.
Should be noted that at last; Above content is only in order to explain the technical scheme of this utility model; But not to the restriction of this utility model protection domain; The simple modification that those of ordinary skill in the art carries out the technical scheme of this utility model perhaps is equal to replacement, does not all break away from the essence and the scope of this utility model technical scheme.
