Description
Technical field
A kind of neonate nostril of the invention lighting device belongs to the neck such as neonate's articles for use, paediatrics medicine equipment and illumination optical
Domain.
Background technology
Nose dung can hinder breathing, give people to bring uncomfortable sensation.When adult has nose dung in nostril, can be certainly
Oneself plucks out nose dung, however, for neonate, due to limb development it is incomplete, it is impossible to it is autonomous to dig nose dung, it is therefore desirable to the side of the head of a family
Help.
But, because neonate does not understand the cooperation head of a family, therefore instinct resistance can be carried out when nose dung is dug, easily make
It is damaged into schneiderian membrane, bring difficulty to the development for digging the work of nose dung, the method for solving this problem be exactly after neonate sleep soundly,
Dig nose dung to neonate again.
Because nose dung is ensconced inside nostril, it is therefore desirable to neonatal nostril is illuminated, this meeting to illuminating bundle
Poly- characteristic has very high requirement, and reason is as follows：
If the first, beam divergence, neonate's eyes can be irradiated to, neonate is waken up from sleeping soundly, cause to dig
The work of nose dung cannot be carried out；
Secondth, neonatal nostril very little, if beam divergence, is likely to result in illumination intensity not enough, can also give digging nose dung
The development of work brings difficulty.
It can be seen that, a lighting device with good convergence function is smoothly to carry out the key that neonate digs the work of nose dung
Auxiliary equipment.
However, either normal lighting lamp, torch, light beam is all diverging, it is impossible to realize assembling the effect of illumination.
The content of the invention
The demand illuminated to nostril in the work of nose dung is dug for carrying out neonate, the present invention devises a kind of neonate nostril
Lighting device, the device can be with very simple structure, there is provided high-quality convergence illuminating bundle.
The object of the present invention is achieved like this：
A kind of neonate nostril lighting device, in inside the shell, along the light direction of propagation object lens, pin hole, annular is set gradually
Printing opacity shutter and ellipsoidal mirror；The objective focus positions and ellipsoidal mirror over focus position overlap, overlapping position
Pin hole is set；Collimated light beam forms spot light along optical axis direction illumination objective in pin hole position, then anti-through ellipsoidal mirror
Perifocus position is incident upon, a hot spot is converged to；Annular printing opacity shutter can be between pin hole and ellipsoidal mirror along optical axis
Direction is moved, and the outer shroud and inner ring of annular printing opacity shutter are sized to adjustment.
Above-mentioned neonate nostril lighting device, the outer shroud of the annular printing opacity shutter is sized to adjustment, by following
Structure is realized：
On the outer shroud of annular printing opacity shutter, multilayer external part is installed, is annulus after every layer of external part is fully extended
Shape, is concentric two annulus after adjacent two layers external part is fully extended, and large circle inner circle and small circle ring it is cylindrical heavy
Close.
Above-mentioned neonate nostril lighting device, the inner ring of the annular printing opacity shutter is sized to adjustment, by following
Structure is realized：
On the outer shroud of annular printing opacity shutter, n expansion link is installed, the end of each expansion link is provided with sector
Structure, the central angle of the sector structure is 360/n.
Above neonate nostril lighting device, annular printing opacity shutter can be between pin hole and ellipsoidal mirror along light
Direction of principal axis is moved, and is realized by following structure：
The sidewall symmetry of the printing opacity shutter is provided with two support ends, and shell is symmetrically arranged with two the second grooves,
The support end stretches out from the second groove；Screw thread is cased with shell, ring rotation end is by the rotation of shell outer wall thread
Realize moving forward and backward, on the end face at ring rotation end, be provided with recess, the recess inner surface and bearing outer ring interference fit
Install, in bearing inner race, interference fit installs annular connection end, and the annular connection end connects support end.
Beneficial effect：
Firstth, in neonate nostril of the present invention lighting device, due in inside the shell, along the light direction of propagation thing being set gradually
Mirror, pin hole, annular printing opacity shutter and ellipsoidal mirror, number of elements is few, therefore the technical advantage with simple structure；
Secondth, in the lighting device of neonate nostril of the present invention, due to being provided with annular printing opacity shutter, therefore provide
It is ring illumination light, only irradiates nostril side wall, and do not irradiate inside nostril, compared with circular illumination light beam, except equally has
Outside technique effect to the illumination of nostril side wall, also with the effect of protection nostril inside schneiderian membrane；
3rd, in the lighting device of neonate nostril of the present invention, because annular printing opacity shutter can be in pin hole and ellipsoid
Move along optical axis direction between the speculum of face, the outer shroud and inner ring of annular printing opacity shutter are sized to adjustment, therefore, it is possible to logical
Mobile annular printing opacity shutter is crossed, changes outer shroud and inner ring size, the inside and outside loop diameter of the annular illuminating bundle of adjustment, illumination angle
Degree, exposure intensity so as to different nose shapes, the baby of size can be applied to, the applicable model of nostril lighting device is increased
Enclose；
4th, in the lighting device of neonate nostril of the present invention, due to carrying out light beam convergence using ellipsoidal mirror, together
Conventional lenses are assembled mode and are compared, and speculum can solve the Aberration Problem of lens from principle, realize irradiating baby without veiling glare
Youngster's eyes, are prevented effectively from divergent beams or have aberration convergent beam baby is waken up from sleeping soundly, and cause to dig the work of nose dung
The problem that cannot be carried out；
5th, in the lighting device of neonate nostril of the present invention, ellipsoidal mirror bifocus conjugated nature is made full use of,
Utilizing can also be anti-with lens arrangement or plane mirror or sphere from the property of over focus outgoing from the incident light beam of over focus
Penetrate mirror to compare, the beneficial effect with large angle illumination so that illuminating bundle ends in nostril side wall, further in protection nostril
The schneiderian membrane in portion.
