The specific embodiment
This utility model utilizes the interior empty passage of endotracheal tube itself, makes it be enclosed within the light pipe last time and completes the intubate task, and utilize neck soft printing opacity principle to come guidance tracheal intubation, and transdermal halation is indicated as the degree of depth.
The anesthetic laryngopharyngoscope that this utility model provides, its structure as shown in Figures 1 to 4, comprise light pipe, handle casing 12, red laser luminous tube 6 and power supply, light pipe, lasing fluorescence pipe 6 are connected successively with power supply, and red laser luminous tube 6 and power supply are arranged in the inner chamber of handle casing 12.
Described light pipe is comprised of compo pipe 1, printing opacity rod 2, and major function is HONGGUANG that the lasing fluorescence pipe is sent by the output of printing opacity rod so that illumination to be provided, and this HONGGUANG can transdermal halation instructs the degree of depth of intubate.Described compo pipe can be made by the corronil material, and this compo pipe front portion 1/3rd is soft attitude alloy, crooked and typing arbitrarily, and maximum bend angle is not less than 90 degree, and rear portion 2/3 length is hard attitude, facilitates quick and precisely intubate of doctor; The termination, rear portion is stretched in the inner chamber of handle casing 12 after passing the inner chamber of light pipe fixed mount 3, with red laser luminous tube 6 emission port plane contact.Printing opacity rod 2 is arranged in the inner chamber of compo pipe, and its front end stretches out 40 millimeters of compo pipe front ends, and its rear end passes 2 millimeters of compo pipes, stretch into handle casing 12 inner chamber and in be connected with red laser luminous tube 6.
Described light pipe fixed mount 3 is connected with handle casing 12 screw threads, and this fixedly erects the effect of supporting fixing light pipe and fastening by screw 4, comes off to prevent light pipe.
its lead-in wire of red laser luminous tube 6 is connected the assembly indication pad that forms and is connected with the electric quantity detecting circuit plate with electric weight display screen 8, the red laser luminous tube that red laser luminous tube 6 is placed in components and parts fixed mount 10 is installed in cavity 14 (being penetrated by lead end), luminous component is installed cavity 14 outer surface levels with the red laser luminous tube and is flushed, the assembly of electric weight display screen 8 and 9 formation of electric quantity detecting circuit plate is placed on the platform of components and parts fixed mount 10, like this by components and parts fixed mount 10, electric quantity detecting circuit plate 9, electric weight display screen 8 and red laser luminous tube 6 newly are combined into an assembly.The function of this assembly is: (1) shows with battery electric quantity, is conducive to the dump energy situation of this product of Real-Time Monitoring; When (2) battery electric quantity was not enough, buzzing alarming was reminded, thereby occurred cutting off the power supply suddenly because electric weight is not enough when avoiding the clinical anesthesia intubate, caused observing the degree of depth of tracheal intubation, the injures and deaths risk that can effectively avoid the secondary intubate to bring to patient like this.
Assembling: components and parts fixed mount 10, electric quantity detecting circuit plate 9, electric weight display screen 8 and red laser luminous tube 6 newly are combined into an assembly pack in the inner chamber of handle casing 12, wherein: electric weight display screen 8 will show that window 7 is placed in the middle with the electric weight display screen above handle casing 12.There is tap partly to penetrate as front end the assembly front end that is formed by compo pipe 1, printing opacity rod 2, light pipe fixed mount 3, holding screw 4 handle casing upper cover 5, block at last light pipe fixed mount 3, handle casing upper cover 5 is connected with the front end spiral of handle casing 12.The positive level of battery 11 in front being loaded on battery compartment 15, is threaded belt switch handle bonnet 13 at last with handle casing 12 rear ends.
This product is after removal electric weight display screen shows window 7, electric weight display screen component 8, electric quantity detecting circuit plate 9 electric weight display units, and except electric weight observation inconvenience, this product still can work, and this belongs to the product rights scope together.
This utility model is applicable to observe the tracheal intubation of air flue, convenient and swift per os, nasotracheal tube and difficult airway.
Using method is: crooked light pipe → power-on → observation electric weight → implementation and operation as required.Specific as follows:
1, at first use disinfectant solution that light pipe is carried out disinfection;
2, start on and off switch, check battery capacity indication, when guaranteeing to use, electric weight is sufficient;
3, before tracheal intubation, at first with lubricator sufficient lubrication light pipe outer wall and trachea catheter proximal end; Then light pipe is inserted in endotracheal tube, make the light pipe tip be positioned at the front end of endotracheal tube and not exceed endotracheal tube; Then in the proximal end near cuff for endotracheal catheter top, endotracheal tube-light pipe complex is folded into suitable angle with standby.
4, after induction of anesthesia, adjust patient's position, operator's left hand is to the front upper patient's lower jaw of mentioning, also can be by assistant's both hands of operator to front upper lower jaw of mentioning the patient, to enlarge the ccavum oropharygeum gap, the right hand is held endotracheal tube-light pipe complex and is inserted or insert from bicker again from the center, oral cavity its pendulum is hit exactly to the oral cavity simultaneously.When endotracheal tube-when light pipe complex front end was positioned at back of tongue, extreme direction before adjusting made endotracheal tube-light pipe complex aim at the glottis opening direction; Note observing the position whether anterior region of neck has hot spot and hot spot, adjust and mobile endotracheal tube-light pipe complex according to facula position.Clear bright hot spot appears in the place when cervical region ring first film, when hot spot presents to the light beam of trachea extension, prompting endotracheal tube-light pipe complex front end has been aimed at glottis, and this moment, the right hand kept light pipe to fix, and left hand slowly pushes to appropriate depth in trachea with endotracheal tube.If the throat hot spot appears at Adam's apple top, light intensity a little less than, point out the front end of endotracheal tube-light pipe complex may push up epiglottic vallecula; If the very disperse of throat hot spot, almost illegible, normal prompting may be strayed into esophagus by endotracheal tube; If meet obstructions in the intubate process, hot spot deflection cervical region one side can suitably withdraw from or left-right rotation endotracheal tube-light pipe complex, returns in case of necessity, and examination is inserted again.
This utility model is simple in structure, easy to use, which kind of position of patient no matter, the tracheal intubation of light pipe guiding can be set up rapidly, safe and effective air flue, for some patient that can only keep lateral position, using the light pipe guide cannula is a kind of good selection.
