Description
The application is the divisional application of application for a patent for invention " a kind of newborn nostril lighting device ".
Original bill application number: 2017100209129.
The original bill applying date: 2017-01-11.
A kind of original bill denomination of invention: newborn nostril lighting device.
Technical field
A kind of outer ring structure of the present invention and the newborn nostril lighting device with the structure belong to newborn's articles, paediatrics
The fields such as medical instrument and illumination optical.
Background technique
Nose dung can hinder to breathe, and bring uncomfortable feeling to people.It, can be certainly when adult has nose dung in nostril
Oneself plucks out nose dung, however, since limb development is not complete, can not independently dig nose dung, it is therefore desirable to the side of parent for newborn
It helps.
But since newborn does not understand cooperation parent, instinct resistance can be carried out when digging nose dung, is easy to make
At schneiderian membrane breakage, difficulty is brought to the development that nose dung works is dug, solves the method for this problem exactly after newborn sleep soundly,
Nose dung is dug to newborn again.
Since nose dung is ensconced inside nostril, it is therefore desirable to be illuminated to neonatal nostril, this meeting to illuminating bundle
Poly- characteristic has very high requirement, the reason is as follows that:
If first, beam divergence, newborn's eyes can be irradiated to, wake up newborn from sleeping soundly, cause to dig
The work of nose dung can not carry out；
The second, neonatal nostril very little, if beam divergence, it is inadequate to may cause illumination intensity, also can be to digging nose dung
The development of work brings difficulty.
As it can be seen that a lighting device with good convergence function, is the key that smooth newborn's digging nose dung of carrying out works
Ancillary equipment.
However, either normal lighting lamp, flashlight, light beam are all divergings, the effect for assembling illumination cannot achieve.
Summary of the invention
The demand illuminated in the work of nose dung to nostril is dug for newborn is carried out, the present invention devises a kind of newborn nostril
Lighting device, the device can provide the convergence illuminating bundle of high quality with very simple structure.
The object of the present invention is achieved like this:
A kind of newborn nostril lighting device sets gradually object lens, pin hole, annular along the light direction of propagation inside the shell
Light transmission shutter and ellipsoidal mirror；The objective focus positions and ellipsoidal mirror over focus position are overlapped, overlapping position
Pin hole is set；Collimated light beam forms point light source along optical axis direction illumination objective, in pin hole position, anti-using ellipsoidal mirror
It is incident upon perifocus position, is converged to a hot spot；Annular light transmission shutter can be between pin hole and ellipsoidal mirror along optical axis
Direction is mobile, and the outer ring and inner ring size of annular light transmission shutter can adjust.
The outer ring size of above-mentioned newborn nostril lighting device, the annular light transmission shutter can adjust, by following
Structure is realized:
On the outer ring of annular light transmission shutter, multilayer extension end is installed, is annulus after every layer of extension end is fully extended
Shape, after adjacent two layers extension end is fully extended, for two concentric annulus, and the outer circle weight of the inner circle of large circle and small circle ring
It closes.
The inner ring size of above-mentioned newborn nostril lighting device, the annular light transmission shutter can adjust, by following
Structure is realized:
On the outer ring of annular light transmission shutter, n telescopic rod is installed, the end of each telescopic rod is equipped with sector
Structure, the central angle of the sector structure are 360/n.
Above newborn nostril lighting device, annular light transmission shutter can be between pin hole and ellipsoidal mirrors along light
Axis direction is mobile, by being realized with flowering structure:
There are two support end, shell is symmetrical arranged there are two the second through slot for the sidewall symmetry setting of the light transmission shutter,
The support end is stretched out from the second through slot；It is cased with screw thread on the shell, ring rotation end in shell outer wall thread by rotating
It realizes and is moved forward and backward, on the end face at ring rotation end, be provided with recess, the recess inner surface and bearing outer ring are interference fitted
Installation, in bearing inner race, interference fit installs annular connecting pin, and the annular connecting pin connects support end.
The utility model has the advantages that
The first, in newborn nostril of the present invention lighting device, due to inside the shell, setting gradually object along the light direction of propagation
Mirror, pin hole, annular light transmission shutter and ellipsoidal mirror, number of elements is few, therefore has the simple technical advantage of structure；
The second, it in the lighting device of newborn nostril of the present invention, due to being provided with annular light transmission shutter, provides
It is ring illumination light, only irradiates nostril side wall, without irradiating inside nostril, compared with circular illumination light beam, in addition to equally has
Outside the technical effect illuminated to nostril side wall, also have the function of protecting schneiderian membrane inside nostril；
Third, in the lighting device of newborn nostril of the present invention, since annular light transmission shutter can be in pin hole and ellipsoid
It is moved between the reflecting mirror of face along optical axis direction, the outer ring and inner ring size of annular light transmission shutter can adjust, therefore can lead to
Mobile annular light transmission shutter is crossed, outer ring and inner ring size are changed, adjusts the inside and outside loop diameter of annular illuminating bundle, illumination angle
Degree, exposure intensity can be suitable for the baby of different nose shapes, size, increase the applicable model of nostril lighting device
It encloses；
4th, in the lighting device of newborn 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 reflecting mirror can solve the Aberration Problem of lens from principle, realize and irradiate baby without stray light
Youngster's eyes effectively avoid divergent beams or have aberration convergent beam to wake up baby from sleeping soundly, and cause to dig the work of nose dung
Can not carry out the problem of；
5th, in the lighting device of newborn nostril of the present invention, ellipsoidal mirror bifocus conjugated nature is made full use of,
The property that can also be emitted from the light beam of over focus incidence from over focus is utilized, it is anti-with lens arrangement or plane mirror or spherical surface
It penetrates mirror to compare, the beneficial effect with large angle illumination, so that illuminating bundle ends in nostril side wall, further protect in nostril
The schneiderian membrane in portion.
