Problems solved by technology

[0005] First, if the beam of light diverges, it will irradiate the newborn's eyes, causing the newborn to wake up from a deep sleep, making it impossible to pick boogers;
[0006] Second, the nostrils of newborns are very small. If the light beam diverges, it may cause insufficient lighting intensity, and it will also bring difficulties to the development of nose excrement work.
[0008] However, whether it is a daily lighting lamp or a flashlight, the light beams are divergent, and the function of convergent lighting cannot be achieved.

specific Embodiment 1

[0033] The structure diagram of the neonatal nostril lighting device of this embodiment is as follows: figure 1 As shown, the neonatal nostril illuminating device is inside the casing 5, and the objective lens 1, the pinhole 2, the ring-shaped light-transmitting shielding plate 3 and the ellipsoid reflector 4 are sequentially arranged along the light propagation direction; the focal position of the objective lens 1 and the ellipsoid reflection The positions of the far focal points of the mirrors 4 are coincident, and a pinhole 2 is set at the overlapping position; the parallel light beam irradiates the objective lens 1 along the optical axis direction, and a point light source is formed at the position of the pinhole 2, and then reflected by the ellipsoid mirror 4 to the near focal point, and converged into a point spot; The annular light-transmitting shielding plate 3 can move along the optical axis direction between the pinhole 2 and the ellipsoidal mirror 4, and the size of ...

specific Embodiment 2

[0035] The neonatal nostril lighting device of this embodiment, on the basis of the specific embodiment 1, further defines that the size of the outer ring of the annular light-transmitting shielding plate 3 can be adjusted, and is realized by the following structure:

[0036] On the outer ring of the ring-shaped light-transmitting shielding plate 3, a multi-layer extension end 31 is installed. After each layer of extension end 31 is fully extended, it becomes a circular ring. After two adjacent layers of extension end 31 are fully extended, It is two concentric rings, and the inner circle of the big ring coincides with the outer circle of the small ring.

[0037] In this embodiment, the relationship between the annular light-transmitting shielding plate 3 and the extended end 31 is as follows: figure 2 As shown; what needs to be explained to this figure is that the extension end 31 installed on the outer ring of the annular light-transmitting shielding plate 3 has 2 layers, w...

specific Embodiment 3

[0040] The neonatal nostril lighting device of this embodiment, on the basis of the specific embodiment 1, further defines that the size of the inner ring of the annular light-transmitting shielding plate 3 can be adjusted, and is realized by the following structure:

[0041] On the outer ring of the annular light-transmitting shielding plate 3, n telescopic rods 32 are installed, and the end of each telescopic rod 32 is mounted with a fan-shaped structure 33, and the central angle of the fan-shaped structure 33 is 360 / n.

[0042] The connection relationship between the outer ring, the telescopic rod 32 and the fan-shaped structure 33 is as follows: Figure 4 shown. It should be explained that in the attached Figure 4 , the number of telescopic rods 32 is 4, which will cause the inner ring to degenerate into a square at the minimum; however, those skilled in the art can imagine that as the number of telescopic rods 32 increases, the inner ring will gradually approach a circl...

Abstract

The invention discloses a newborn nostril illumination device, and belongs to the fields of newborn supplies, pediatric medical apparatuses and instruments, optical illumination and the like. The illumination device is sequentially provided with an objective lens, a pinhole, an annular light-transmitting baffle and an ellipsoidal reflector in a housing along the propagation direction of a light ray; the focus position of the objective lens and the apofocus position of the ellipsoidal reflector are superposed, and the pinhole is formed in the superposed part; and a parallel beam irradiates the objective lens along the direction of an optical axis, forms a point light source at the position of the pinhole, and then is reflected to a perifocus position through the ellipsoidal reflector and converged to form point light spots; and the annular light-transmitting baffle is capable of moving between the pinhole and the ellipsoidal reflector along the direction of the optical axis, and the dimensions of an outer ring and an inner ring of the annular light-transmitting baffle are adjustable. The newborn nostril illumination device disclosed by the invention is capable of providing a high-quality converged illumination beam by virtue of a quite simple structure.

Description

technical field [0001] The invention relates to a neonatal nostril lighting device, which belongs to the fields of neonatal supplies, pediatric medical equipment, optical lighting and the like. Background technique [0002] Boogers obstruct breathing and can be uncomfortable. When adults have boogers in their nostrils, they can pick out the boogers by themselves. However, for newborns, due to their underdeveloped limbs, they cannot dig out the boogers independently, so they need the help of their parents. [0003] However, because newborns do not know how to cooperate with their parents, they will instinctively resist when digging their noses, which may easily cause damage to the nasal mucosa and bring difficulties to the work of picking noses. , and then pick the newborn’s booger. [0004] Since boogers are hidden inside the nostrils, it is necessary to illuminate the nostrils of newborns, which has high requirements on the converging characteristics of the lighting beam,...
