Description
Technical field
This utility model high-brightness LED sidelight hard optical wand is a kind of for the auxiliary facilities through human body throat, the medical examination of respiratory tract tracheal intubation.
Background technology
At present, the lighting source of existing tracheal intubation optical wand has electric filament lamp that LED is also arranged, and the low heating of the low luminous efficiency of incandescent lamp bulb brightness is serious, scalds the patient easily.And the low operation of need turning off the light of brightness.So have only the strong light utilization efficiency of HONGGUANG penetrance also very low, be tending towards superseded.
Red-light LED has been used for optical wand, but because ready-made 3 millimeters and 5 millimeters LED electric current have only 20 milliamperes, list only uses brightness, and too low penetration power is poor, the great power LED installation volume can't enter trachea inside greatly, so use fiber optic conduction light, the loss of the big frangibility split of optical fiber shortcoming transmission loss difficult design seam can't guarantee constant.
The angular deviation of single angle light scattered light, light utilization is poor, existing intubate optical wand light is launched at a certain angle towards dead ahead, yet trachea rear wall and two sidewalls do not need illumination because can't see hot spot, the axial of trachea do not need to throw light on yet, and shining to trachea carina also is to see hot spot.The material aspect uses plastic type soft material matter not to be durable, and poor controllability is met difficulty the moulding after strain of air flue can't correctly perception tip location.Soft moulding optical wand angle is difficult to accurately control and firmly the back is yielding, reinvents type after the feel variation often need be extracted after the distortion rear tip change in location, is easy to like this patient is caused secondary damage, increases intubation time.Existing optical wand interface exposes or for one designs, can't sterilize, and can't accomplish a people one utensil.
The utility model content
Deficiency at the low operation of need turning off the light of the serious brightness of the low heating of existing intubate optical wand incandescent lamp bulb luminous efficiency, the most advanced and sophisticated integrated two groups of red-light LED light emitting diodes that are mutually 90 degree of this utility model, the hard barred bodies of 106 degree: be connected in and become 106 to spend with the tip, dress lead in the hollow metal barred body, barred body, lead one end is connected in LED lumination of light emitting diode body, the other end is connected in handle with the slip interface, T-handle: handle includes battery compartment, constant-current drive circuit, and barred body slip interface.Integrated 4 the high brightness paster LED light emitting diodes in the luminous tip of this utility model apparatus, form two groups of red-light LED light emitting diodes that are mutually 90 degree, based on sidelight, integrated, every group is connected by two highlighted red-light LED light emitting diodes series connection and to be integrated in lucite inside, two groups are parallel to constant-current circuit, make four LED light-emitting diode luminances identical, make luminous most advanced and sophisticated two groups of luminous body lighting angles in same plane, become 90 degree, LED efficient height generates heat hardly, so can not scald patient's tracheal mucosa.First insulation processing is injected the paste heat-conducting cream then after the luminous most advanced and sophisticated wiring in the barred body tube chamber, and insulating resin encapsulation then imports barred body to heat with the LED pin by heat-conducting cream, solves the concentrated high temperature problem that causes of heat.
Change the light-path of traditional optical wand; Existing intubate optical wand light is launched at a certain angle towards dead ahead, yet, trachea rear wall and two sidewalls do not need illumination because can't see hot spot, the axial of trachea do not need to throw light on yet, according to also being to see hot spot to trachea carina, has only the antetheca intubate success back visible light spot of trachea.The utlity model has the hard hollow metal tube of 106 degree as barred body, the circular arc of the physiological bendings that itself and luminous most advanced and sophisticated formation 106 are spent, arc length is 12.5 centimetres of 15 centimetres, chord length, and the head end tangent line is luminous tip, and other end tangent line becomes 30 degree angles with barred body.Luminous tip has only the LED light of both direction.Axial ray is used to indicate the larynx position, inboard probeing into enters the equal directive trachea of its all light of trachea antetheca if sidelight is positioned at 106 degree circular arcs, the light utilization height is so hot spot is very bright and concentrated, so intubate is not subjected to the influence of the surround lighting operation of can not turning off the light.
Existing optical wand adopts plastic type material poor controllability, and is yielding in the moulding intubate process of the air flue of meeting difficulty, can't correctly perception tip location after the distortion.Soft moulding optical wand angle is difficult to accurately control and firmly the back is yielding, reinvents type after the feel variation often need be extracted after the distortion rear tip change in location, is easy to like this patient is caused secondary damage, increases intubation time.This utility model barred body physiological bending angle 106 degree: adopt the physiological bending hard material, the angle of oropharynx and laryngopharynx is about 106 degree, fix 106 degree and be applicable to most patients, for only a few difficult airway patient, can cooperate cervical region to bend and stretch position offset angle deviation and finish tracheal intubation.Front tooth generally just in time satisfies physiology length at 13cm to 15cm design entry arc length 15cm to the glottis distance.Barred body intubate offset angle 30 degree: too stretch without forearm when barred body interface and barred body front end circular arc tangential line angle 30 are spent the operator is operated and block operator's sight line.
The T-handle fitted shaft is to anti-rotation interface, makes the operator be easier to axially rotate the apparatus operator and is used for the perception patient with the operation of thumb forefinger district.Existing staight shank optical wand is with the little finger of toe hypothenar region or with thumb forefinger middle finger perception patient, poor sensitivity operating difficulties.
T shape band elasticity has handle slip interface and is convenient to connect dismounting and regulating rod body length from the handle of locked switch.Anti-rotation scalable built-in slip interface is convenient to regulate barred body and is used length to adapt to different catheter lengths, and the built-in health of interface is convenient to dismantle the back sterilization.
This utility model can be widely used in conventional tracheal intubation, difficult tracheal intubation.
This utility model is not limited to above-mentioned embodiment, adopts the structure identical or approximate with this utility model above-described embodiment, and the optical wand that obtains.And minification is for the children with tracheal intubate, all within protection domain of the present utility model.
Below in conjunction with accompanying drawing and the specific embodiment, this utility model is further specified.
