With the endotracheal tube of anesthetics spray structure
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of endotracheal tube with anesthetics spray structure.
Background technology
Endotracheal intubation refers to the technology endotracheal tube of a Gent being inserted patient airway through glottis, and this technology can attract for airway unobstructed, ventilation oxygen-supplying, respiratory tract and prevent suction by mistake etc. from providing optimum condition.When carrying out endotracheal intubation, generally need carry out local anesthesia to places such as the bottleneck throat of patient and glottises, to ensure that the patient of the reflection sensitive such as bottleneck throat, glottis can cooperate, endotracheal tube being inserted smoothly.But As time goes on, the drug effect of anesthetics loses gradually, and patient enters the recovery from anesthesia phase, and its bottleneck throat is regained consciousness, owing to inserting endotracheal tube, patient just there will be to choke and the not resistance to pipe symptom such as to cough, and makes patient feel more painful.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of endotracheal tube with anesthetics spray structure, patient is helped to set up in the process of respiration channel utilizing this endotracheal tube, can again anaesthetize bottleneck throat easily and fast, make bottleneck throat maintain long-term anaesthetic effect, avoid making patient to occur choking and the not resistance to pipe symptom such as to cough.
This utility model is solved the problem by following technological means: a kind of endotracheal tube with anesthetics spray structure, comprise body, drug liquid tube and be arranged on the medicine bag arranged outside body and near body upper end, described tube body wall is provided with nozzle near body lower end, described drug liquid tube one end is communicated with nozzle, and the other end is communicated with described medicine bag.
Further, described nozzle is inlayed with tube body wall and is connected.
Further, institute's nozzle comprises nozzle body, is provided with feeding-passage and nozzle bore in described nozzle body.
Further, the longitudinal cross-section of described nozzle bore is V-arrangement.
The beneficial effects of the utility model: the endotracheal tube of band anesthetics spray structure of the present utility model, comprise body, drug liquid tube and be arranged on the medicine bag arranged outside body and near body upper end, described tube body wall is provided with nozzle near body lower end, described drug liquid tube one end is communicated with nozzle, and the other end is communicated with described medicine bag.The endotracheal tube of the band anesthetics spray structure of this structure, patient is helped to set up in the process of respiration channel utilizing this endotracheal tube, again can anaesthetize bottleneck throat easily and fast, make bottleneck throat maintain long-term anaesthetic effect, avoid making patient to occur choking and the not resistance to pipe symptom such as to cough.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of nozzle.
Detailed description of the invention
Below with reference to accompanying drawing, this utility model is described in detail, as depicted in figs. 1 and 2: a kind of endotracheal tube with anesthetics spray structure, comprise body 1, drug liquid tube 2 and the medicine bag 3 being arranged on outside body and close body upper end layout, described tube body wall is provided with nozzle 4 near body lower end, certainly, also multiple nozzle can be evenly set in body lower end circumference, to guarantee comprehensive spraying medicine, described nozzle is inlayed with tube body wall and is connected, after endotracheal tube inserts, the outlet of nozzle is towards bottleneck throat, described drug liquid tube can be fixed on inboard wall of tube body, also tube wall can be fixed on, described drug liquid tube one end is communicated with nozzle, the other end is communicated with described medicine bag.The endotracheal tube of the band anesthetics spray structure of this structure, when bottleneck throat needs again to anaesthetize, in medicine bag, anesthetics is injected by medicine bag feeding opening by syringe, then close medicine bag feeding opening, extruding medicine bag, makes anesthetics be sprayed by nozzle after drug liquid tube, again can anaesthetize bottleneck throat, whole process fast and easy, avoids patient in endotracheal intubation and occurs extra misery.Medicine bag can store medicinal liquid on the one hand, and squeeze force is different on the other hand, can control jet velocity and atomizing effect.
As the further improvement to technique scheme, institute's nozzle comprises nozzle body 41, is provided with feeding-passage 42 and nozzle bore 43 in described nozzle body, and the longitudinal cross-section of described nozzle bore is V-arrangement.Like this, medicinal liquid is through the ejection of V-arrangement nozzle bore, and two bursts of opposed jets are collided mutually, can improve the atomizing effect of anesthetic liquid medicine, thus improves the dopey efficiency of bottleneck throat.
In addition, said nozzle also can be designed to the cuff it carrying spray apertures, and cuff is socketed in outside body, and described cuff is connected with drug liquid tube.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail this utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
