Abstract
This utility model announces a kind of automatic light source guiding tube of the scalable direction for clinical nasal trachea cannula.Comprise flexible conduit; Described catheter proximal end is fixed with midget lamp, and rear end of conduit is fixed with the power supply for powering to midget lamp; Just go up in catheter proximal end, left and right 3 places are fixed with tinsel, have three along duct direction, internal channel corresponding with tinsel fixing point respectively inside catheter wall, described tinsel is each passed through corresponding internal channel and passes conduit from the rear end of conduit.During use, light rope is inserted in endotracheal tube, opens midget lamp, for subsequent use.Operator's left hand adjustment patient lower jaw makes its cervical region even up as far as possible, the right hand will be with the endotracheal tube of light rope through nostril Zhi Ren patient throat, observe throat luminous point, regulate light rope position, and by pulling tinsel to regulate endotracheal tube leading portion direction, until a bright luminous point is seen in center under Adam's apple, hot spot concentrate and the brightest time insert endotracheal tube, at this moment endotracheal tube is in tram.
Description
Technical field
This utility model relates to a kind of medical medical apparatus and instruments, specifically a kind of automatic light source guiding tube of the scalable direction for clinical nasal trachea cannula.
Background technology
Endotracheal intubation refers to special endotracheal tube, is inserted in patient's trachea by oral cavity or nasal cavity.The technology being a kind of endotracheal anesthesia and give emergency treatment to a patient, be also the most reliable means keeping upper respiratory tract unobstructed, it is widely used in general anesthesia, and respiratory failure needs to carry out mechanical ventilation person, cardio-pulmonary resuscitation, drug intoxication and neonate severe asphyxia.For needing the current situation of all-level hospitals of the patient of emergency cannula mainly to see and treat patients doctor to carry out tracheal intubation, but carry out endotracheal intubation difficulty greatly with laryngoscope for gengral practitioner, success rate is low.Often need to ask anesthetist to go to assist intubate, so both add the time also wasting manpower and material resources of patient's anoxia asphyxia.And the tracheal intubation of general patient is realized through the application laryngoscope that the anesthetist of professional training can be skilled, difficult tracheal intubation patient then needs some special apparatuses or means, and the intubation procedure of current difficult tracheal intubation patient can select simple per nasal blind tracheal intubation usually, driving in the wrong direction guides conscious intubation and fiberoptic larygoscope guide cannula method.The problem of intubate although these methods can be overcome a difficulty substantially, but also Shortcomings: simple per nasal blind tracheal intubation and the guiding conscious intubation that drives in the wrong direction have certain blindness, ring first film may be had in retrograde operation to split, the complication such as hematoma and hoarseness, and be subject to the restriction of patient's cervical region mobility, intubation is comparatively large to bottleneck throat soft-tissue trauma, length consuming time, and hemodynamics fluctuation obviously; Although branchofiberoscope and fiberoptic larygoscope more directly perceived, if but ccavum oropharygeum exist obviously hemorrhage or secretions is more time, then easily cause exposing unclear, and price is very expensive, its optical fiber is easily damaged, and successful intubation is larger by operating technology experience influence.
Utility model content
For solving the problems of the technologies described above, this utility model provide a kind of scalable direction through nasal intubation automatic light source guiding tube.
This utility model is by the following technical programs: a kind of scalable direction through nasal intubation automatic light source guiding tube, comprise soft flexible conduit; Described catheter proximal end is fixed with midget lamp, and rear end of conduit is fixed with the power supply for powering to midget lamp; Just go up in catheter proximal end, left and right 3 places are fixed with tinsel, have three along duct direction, internal channel corresponding with tinsel fixing point respectively inside catheter wall, described tinsel is each passed through corresponding internal channel and passes conduit from the rear end of conduit.
It is further: described tinsel is just the going up of distance catheter proximal end 0.1-0.3cm place, left and right 3 positions at supravasal fixing point.
Described rear end of conduit is fixed with power pack, and described power supply is arranged in power pack, and power pack is provided with the switch controlling described midget lamp.
When tracheal intubation, this automatic light source of sufficient lubrication guiding tube and endotracheal tube, insert guiding tube in endotracheal tube, is placed in the front end of guiding tube apart from catheter tip about 0.3 cm place, opens midget lamp, for subsequent use.Dim room luminosity, operator's left hand adjustment patient lower jaw makes its cervical region even up as far as possible, the right hand will be with the endotracheal tube of automatic light source guiding tube through nostril Zhi Ren patient throat, during about distance nostril about 17 ~ 19cm, fixing endotracheal tube advances guiding tube 2-3cm, notes observing throat luminous point, regulate guiding tube position, and by pulling tinsel to regulate endotracheal tube leading portion direction, until a bright luminous point is seen in center under Adam's apple, hot spot concentrate and the brightest time insert guiding tube 4-5cm.Fix guiding tube, propelling endotracheal tube to 24-26cm backed off after random guiding tube connects aeration equipment and auscultation or PetCO2 confirm that whether conduit is at tracheal strips.
The utility model has the advantages that: during automatic light source guiding tube guide cannula, overlap without the need to mouth, pharynx and larynx three axle, alleviate the stimulation to throat and tracheal mucosa to a certain extent, make cardiovascular indicators fluctuating margin less; Also not necessarily can be successful for some visible laryngoscopes, or mouth opening is little cannot use laryngoscope at all, even can not oral trachea cannula, when respiratory tract or digestive tract have an active hemorrhage, fibre bronchus mirror is lack scope for their abilities; The difficult intubation patient found after induction, bottleneck throat is often badly mutilated, and visible laryngoscope or fibre bronchus mirror be the region of anatomy not easy to identify also, especially fibre bronchus mirror, due to respiratory arrest, is difficult to intubate at leisure, all add intubate difficulty, can unexpected success be obtained by the method.The method is easy to learn simultaneously, and success rate is high, is applicable to clinical all kinds of medical worker and uses.This kind of apparatus cost is lower, economical and practical, and situation of all-level hospitals and each section office can standingly use.

Detailed description of the invention
Be below a specific embodiment of the present utility model, now by reference to the accompanying drawings this utility model be described further.
As shown in Figure 1, a kind of scalable direction through nasal intubation automatic light source guiding tube, conduit 4 ensures certain degree of hardness but flexible flexible, conduit 4 front end is fixed with midget lamp 5, conduit 4 rear end is fixed with power pack 1, power pack 1 being provided with the power supply 2 for powering to midget lamp 5, power pack 1 being also provided with the switch controlling described midget lamp 5; Distance just the going up of 0.1-0.3cm place, conduit 4 front end, left and right 3 positions are respectively fixed with a tinsel 3, have inside conduit 4 wall three along conduit 4 direction, internal channel corresponding with tinsel 3 fixing point 6 respectively, tinsel 3 is each passed through corresponding internal channel and passes conduit 4 from the rear end of conduit 4, tinsel 3 other end fixes a cross, and the effect of cross conveniently pulls tinsel 3.This light rope is used three one metal wires 3 and is handled, and in actual fabrication with use, also can select other fit system, such as select equally distributed four one metal wires 3.
