Abstract
The utility model provides a novel nasal trachea intubation catheter with a guide structure, comprising an intercalation catheter, an air sac contained at front end of a catheter, a trachea connected with the air sac, and an aeration device. The utility model is characterized in that a plug of an intubation catheter is designed with an inclined oblique shovel shape, a small air sac is sheathed in the air sac, the air sac is connected with one end of a breather line which is inserted into outer wall of the intubation catheter in a single channel, another end of the breather line is connected with the aeration device. The utility model guides doctors to insert the catheter through the nasal cavity without injuring peripheral tissue, the disadvantages of difficulty and risk caused by operation are overcome. Through testing, operations of doctors are simple, which is beneficial to smooth catheter intubation of difficulty patients without life danger caused by the complication.
Description
This utility model belongs to medical apparatus, particularly a kind of novel via intranasal application tracheal intubation conduit with guide frame.
Usually,, insert the oxygen uptake of conduit patients, help breathing to carry out oxygen, carbon dioxide exchange through the oral cavity trachea before the art, keep normal physiological function and be beneficial to operation and carry out smoothly through lung for the patient of the major operation liquor-saturated operation of general anesthesia in other words.But for, neck rigidity short through the bigger micromandible of tracheal intubation difficulty, neck and burn back microstomia, the patient of neck chin adhesion insertion conduit in the oral cavity is but very difficult.Thereby, then adopt the mode of inserting conduit from nasal cavity to solve the problems referred to above clinically for such patient.Yet, in the intubate process,, run into repeatedly the difficulty of intubate owing to insert the limitation of guide-tube structure, not only increase patient's misery, bring complication but also can damage surrounding tissue.Thereby, insert in the smooth and easy insertion trachea of conduit for auxiliary, be inclusive with air bag at the front end of intubate conduit, purpose is that swelling gasbag makes it be adjacent to pharynx rear wall tube head point upward to hold up, confirm to insert direction in the trachea in the intubate process.But in practical operation, practice the defective that still can occur damaging surrounding tissue and increase misery to patient in case operate undercure.
The purpose of this utility model provides a kind of novel via intranasal application tracheal intubation conduit with guide frame, and it guides the doctor avoiding damaging surrounding tissue the process of inserting conduit from nasal cavity, has overcome and has operated the drawback of bringing difficulty and risk.
The purpose of this utility model realizes with following technical scheme: a kind of novel via intranasal application tracheal intubation conduit with guide frame, it has air bag and breather that is communicated with air bag and the aerating device that inserts conduit and be included in catheter proximal end, it is characterized in that: the plug that inserts conduit designs to be according to people's pharynx, larynx position shape has cancave cambered surface and outward-dipping oblique shovel shape, be set with ballonet in the above-mentioned air bag and become bag apparatus in the capsule, and be embedded in vent line one end of inserting on the conduit outer wall with single channel and be communicated with, the other end of vent line is communicated with aerating device.
The ballonet of bag apparatus is arranged on conduit and tiltedly shovels on the intubate duct wall of shape plug tip with side in the above-mentioned capsule.
Be provided with outside oxygen supply conduit in the above-mentioned intubate conduit, its terminal is connected with intubate conduit plug.
It is 35～40 ° that above-mentioned intubate conduit tiltedly shovels the outward-dipping angle of shape plug.
The characteristics that this utility model embodies are: by nasal cavity in patient's intubate process, particularly meeting difficulty in opening mouth can't use under the situation of laryngoscope operation, utilization has the plug in conduit plug of oblique shovel shape and provokes epiglottis, at once capsule gas injection in capsule, by the expansion ballonet, make the intubate conduit plug point upward that is adjacent to the pharynx rear wall hold up, make it aim at the glottis direction, confirm to advance route, help plugging in conduit and insert in the trachea.In progradation progressively, the ballonet that expands is adopted the mode of operation of venting, hold up the catheter tip plug and help just in the conduit insertion trachea, and finish this smoothly after the intubate process while advancing, again to the air vesicle gas injection, fixing endotracheal tube.
Specify this utility model below in conjunction with drawings and Examples.
Accompanying drawing 1 structural representation of the present utility model.
Accompanying drawing 2 plug in conduit plug partial enlarged drawings of the present utility model.
Embodiment 1: a kind of novel via intranasal application tracheal intubation conduit with guide frame, it has intubate conduit 1 and is included in the air bag 2 of intubate catheter proximal end and trachea 3 that is communicated with air bag and aerating device 4, the plug 5 design arc oblique angle that inclines at 45 of intubate conduit, and to have limit, introversion arc oblique angle and limit, flare arc oblique angle angle be that 35--40 ° irregular inclined shovel shape is to design according to the position that pharynx, larynx anatomical structure are beneficial to the insertion endotracheal tube.Its arc oblique angle that inclines exposes glottis the operation epiglottis that the time easily takeoffs.Irregular inclined shovel shape helps intubate conduit 1 and inserts trachea.Be set with 1.5 * 1.2 centimeters ballonet 6 in the above-mentioned air bag 2, its position is arranged on intubate conduit 1 and tiltedly shovels the intubate conduit 1 tube wall upper end of shape plug tip with side.And be communicated with vent line 7 one ends that single channel is embedded on intubate conduit 1 outer wall, the other end of vent line is communicated with aerating device 8, and aerating device 8 can be substituted by syringe.Purpose is by expansion ballonet 6, make insertion intubate conduit plug 5 point upwards that are adjacent to the pharynx rear wall hold up, make it aim at the glottis direction, confirm to advance route, progressively adopting the mode of operation of putting ballonet gas while advancing in the progradation, make it hold up plug in conduit plug 5 and help just in the intubate conduit 1 insertion trachea, and finish this intubate process smoothly.Be provided with outside oxygen supply conduit 9 in the above-mentioned intubate conduit 1, its terminal is connected with plug in conduit plug 5.Purpose is to pass through conduit 9 oxygen supply while operating in operating process, avoids causing anoxia phenomenon.
This utility model proves by experiment: easy and simple to handleization of doctor, and the smooth and easy of intubate conduit that helps inserting trachea carries out the life danger of having avoided complication to bring.
