Abstract
This utility model relates to a kind of endotracheal tube with local anaesthesia function, comprise endotracheal tube body, the lower end of endotracheal tube body is provided with inflatable cuff, endotracheal tube body is provided with nebulization catheter, the opening part of nebulization catheter in endotracheal tube body lower end formed atomization circle around one week, and atomization circle is provided with some apertures.This utility model structure is simple, compact to design, easy to use, at endotracheal tube lower ending opening place, a circle is provided with nebulization catheter, can alleviate endotracheal tube and stimulate patient airway and the discomfort that causes, effectively can improve the comfort level of patient airway's intubate and band pipe.
Description
Technical field
This utility model relates to a kind of endotracheal catheter, belongs to technical field of medical instruments.
Background technology
Endotracheal tube is for ensureing patients with respiratory tract conventional Intubaction device smoothly in general anesthesia, in surgical operation, row endotracheal intubation patient with general anesthesia is at waking up period often because endotracheal tube is to trachea or bronchus, pharyngeal pessimal stimulation and produce cough or the stress such as emotion is impatient, is therefore unfavorable for the treatment of patient.Clinical carry out intubate before usually all can carry out the anesthesia of local to bottleneck throat, but after the drug effect of local anaesthesia is difficult to be maintained to corrective surgery, do not alleviate the stress of During extubation.At present, adopt clinically and directly in endotracheal tube, inject local anaesthetics, because medicine drips excessive, but touch trachea in an instant when excessive medicine drips, be easy to stimulate patient airway thus again choke cough reflection, bring sense of discomfort to patient.
Summary of the invention
The purpose of this utility model is to solve existing endotracheal tube intubate and patient by narcotism to waking up period, endotracheal tube has the problems such as zest discomfort to patient, provide a kind of structure simple, compact to design carries out the endotracheal tube of local anesthesia in intubate and waking up period to patient.
This utility model adopts following technical scheme: a kind of endotracheal tube with local anaesthesia function, comprise endotracheal tube body, the lower end of described endotracheal tube body is provided with inflatable cuff, described endotracheal tube body is respectively arranged with nebulization catheter and inflating catheter, described nebulization catheter along endotracheal tube body from upper end to lower end, the opening part of end in endotracheal tube body lower end of described nebulization catheter formed atomization circle around one week, described atomization circle is provided with some apertures, the upper end of described inflating catheter is connected with charge valve, the end of described inflating catheter is connected in inflatable cuff.
Further, the upper end of described nebulization catheter is connected with syringe by check valve.
Further, the diameter of described nebulization catheter is 0.5 ~ 1mm.
Further, the caliber diameter of described atomization circle is 0.8 ~ 1.5mm.
This utility model structure is simple, compact to design, easy to use, cost of manufacture is lower, is provided with atomization circle, transfers in clear-headed process adopt syringe to inject anesthetics in nebulization catheter at patients with general anesthesia in endotracheal tube lower end, local anaesthetics is made to be sprayed to patient airway's inwall uniformly with vaporific, the emergency reaction that patient brings because of trachea irriate can be alleviated, reduce the generation of adverse events, improve patient comfort degree.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numeral: endotracheal tube body 1, upper end 1-1, lower end 1-2, inflatable cuff 2, nebulization catheter 3, atomization circle 4, syringe 5, inflating catheter 6, charge valve 7, check valve 8.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, a kind of endotracheal tube with local anaesthesia function, comprise endotracheal tube body 1, endotracheal tube body is cylindrical, the upper end 1-1 of endotracheal tube body is for connecting respirator, the lower 1-2 end of endotracheal tube body 1 is trachea socket, the lower end of endotracheal tube body 1 is provided with inflatable cuff 2, endotracheal tube body 1 is provided with nebulization catheter 3 and inflating catheter 6, nebulization catheter 3 and inflating catheter 6 are embedded in the wall chamber of endotracheal tube body 1, the upper end of nebulization catheter 3 is connected with syringe 5 by check valve 8, nebulization catheter 3 along endotracheal tube body 1 from upper end to lower end, nebulization catheter 3 formed atomization circle 4 at the opening part of endotracheal tube body lower end 1-2 around one week, atomization circle 4 is positioned at below inflatable cuff 2, atomization circle 4 is provided with some apertures.The diameter of nebulization catheter 3 is 0.5 ~ 1mm, and the diameter of atomization circle caliber is 0.8 ~ 1.5mm.The upper end of inflating catheter 6 is connected with charge valve 7, and the end of inflating catheter 6 is connected in inflatable cuff 2.
When tracheal intubation, medical personnel's left hand holds laryngoscope exposure patient glottis, the right hand holds endotracheal tube body 1 along patient's corners of the mouth, endotracheal tube body 1 is inserted to patient oral cavity, when endotracheal tube body 1 close near glottis time, the syringe 5 that local anaesthetics is housed is connected check valve 8, injects local anaesthetics fast, local anaesthetics will be sprayed at patient's bottleneck throat with vaporific, play the effect of local anesthesia, afterwards endotracheal tube is inserted tracheal strips.The stress that tracheal intubation is brought can be alleviated like this.Reduce adverse events to occur.When patient transfers waking up period to from general anesthesia state.The syringe that local anaesthetics is housed is connected check valve, injects local anaesthetics fast, local anaesthetics will be sprayed at patient airway's wall with vaporific, play the effect of local anesthesia.Depart from check valve by syringe after each injection, check valve can prevent the generation of gas leak phenomenon.This design can alleviate the emergency reaction that patient airway's irriate brings, and reduces adverse events and occurs, improve patient comfort degree simultaneously.
