Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Fig. 1 is a schematic overall structure diagram of a multispectral switching fiber lighting laryngoscope of a preferred embodiment of the invention. The multispectral switching fiber-optic lighting laryngoscope comprises a laryngoscope handle 110, wherein a connecting part 120 is arranged on the laryngoscope handle 110, and the connecting part 120 is mechanically connected with and fixes a laryngoscope blade 100. The connecting member 120 may be a universal connecting hinge.
Fig. 2 is a schematic view of the internal structure of a laryngoscope handle of a preferred embodiment of the multispectral switching fiber illumination laryngoscope of the invention. An LED lamp module 160 is disposed in the laryngoscope handle 110, and the LED lamp module 160 includes an auxiliary PCB 150, a multispectral LED lamp 140 electrically connected to the auxiliary PCB 150, and a light pipe 130. The light pipe 130 is disposed around the multispectral LED lamp. The multispectral LED 140 can emit light of at least two colors, and when a physician faces various complex internal conditions of the larynx, the physician needs illumination light of different color spectrums to better identify and distinguish the internal space environment of the larynx and obstacles, so as to smoothly perform a throat insertion operation or various other treatments. During the intubation examination or operation of the throat, because of the instability of the patient's physical condition, the physician often encounters the sudden change of the internal structure of the throat, internal bleeding or visual obstruction, and the color of the internal structure of the throat, as well as the possible different colors of the bleeding, obstruction, digesta and vomit, sometimes even the indistinguishable form and color generated by the mixing of the above substances, so the illumination light with a single light source color hardly meets the requirement of the physician during the intubation. The multispectral LED light 140 of the present invention, however, is capable of emitting illumination in at least two color spectrums, providing the practitioner with a choice of colors in the spectrums.
In the process of acting the light source and the object, the warm tone light source is adopted to irradiate the warm color object, the reflection effect is good, and the saturation of the irradiated object is higher; similarly, the cold color object is irradiated by adopting the cold color tone light source, and the whole reflection effect is better than that of other color tone light sources. The corresponding spectrum light source matched with the object reflectivity is used, so that the illumination utilization rate is higher, and the effect is better. Preferably, the multispectral LED lamp 140 may be an RGB three-chip LED lamp or a WRGB four-chip LED lamp or a laser.
The most direct description of a light source illuminating an object is brightness, the reflected brightness into the human eye is perceived as the effective brightness, and related to this is the reflectivity. In general lighting applications, the reflectance of an object is an average reflectance, and the influence on the object with low saturation is relatively small, while a large brightness deviation exists when some objects with high saturation are illuminated. The improvement of effective brightness greatly depends on the efficiency of a light source, a white light illumination light source adopted by a conventional optical fiber laryngoscope is relatively mature, and the light source efficiency can not have a larger promotion space any more; in contrast, the light source efficiency of the multispectral LED lamp 140 employed in the present invention can be improved by controlling or adjusting the multispectral LED lamp by the control circuit. Also importantly, the multispectral LED lamp 140 has good spectral selectivity, which can be designed and controlled to achieve optimal spectral selection. Therefore, the illuminating light with different spectrum colors emitted by the multispectral LED lamp 140 can be directed at the spectrum reflection characteristics of different objects, so that the objects have better reflection brightness, doctors can conveniently and effectively distinguish the laryngeal structure environment and obstacles, and the requirements of the doctors on the illuminating light with various spectrum colors during the intubation of the laryngeal tube are met.
In addition, the optical fiber lighting laryngoscope of the invention uses a single multispectral LED lamp 140 as a light-emitting light source, thereby greatly improving the stability of the light source.
The multispectral LED lamp 140 is disposed and fixed on the auxiliary PCB 150, and the auxiliary PCB 150 and the main PCB 170 are made of a metal substrate material with good heat conduction and heat dissipation performance, and the metal substrate material may be a copper foil substrate or a metal-based copper clad laminate containing an aluminum base or an iron base. The heat emitted from the multispectral LED lamp 140 can be rapidly dispersed through the auxiliary PCB board 150. The two ends of the auxiliary PCB 150 are also in contact with the inner wall of the laryngoscope handle 110, so that the auxiliary PCB 150 can conveniently transfer the heat absorbed by the multispectral LED lamp 140 to the laryngoscope handle 110, thereby ensuring that the multispectral LED lamp 140 is always in a low-temperature working environment and keeping a stable working light-emitting state.
Also provided in the laryngoscope handle 110 is a PCB module 200, the PCB module 200 comprising a main PCB 170, a switch button 180 provided on the main PCB 170 and a battery 190 electrically connected to the main PCB 170. The switch button 180 is electrically connected to the main PCB 170. The PCB module 200 further includes a control circuit (not shown), the control circuit (not shown) is electrically connected to the switching button 180 and the multispectral LED lamp 140, and the user switches the color of the light emitted by the multispectral LED lamp 140 by pressing the switching button 180.

The buttons of the switch button 180 are disposed on the side wall of the laryngoscope handle 110 so that a physician can easily touch and press with a finger to switch the spectral colors emitted by the multispectral LED lights 140 through the switch button 180. The base of the switch button 180 is disposed on the main PCB 170, and the switch button 180 is electrically connected to the control circuit of the main PCB 170. The battery 190 is electrically connected to the multispectral LED lamp 140 through the main PCB 170 and the auxiliary PCB 150, and supplies power to the multispectral LED lamp 140 to enable the multispectral LED lamp to emit light. The main PCB 170 is also made of a material with good heat conduction and dissipation properties, and the upper end of the main PCB 170 is also in contact with the auxiliary PCB 150 to further help the auxiliary PCB 150 to dissipate heat conducted from the multi-spectrum LED lamp 140.
The laryngoscope blade 100 is provided with a fiber tube 90, and the fiber tube 90 is provided with an optical fiber. While the connecting component 120 is mechanically connected and fixes the laryngoscope blade 100, the optical fiber tube 90 is connected and conducted with the light guide tube 130, so that the spectrum emitted by the multispectral LED lamp 140 is transmitted to the light emitting tip (210) of the laryngoscope blade 100 through the optical fibers in the light guide tube 130 and the optical fiber tube 90 in sequence.
The multispectral LED lamp 140 is arranged in the laryngoscope handle 110 instead of the laryngoscope blade 100, the arrangement can separate the detachable laryngoscope blade 100 from the laryngoscope handle 110, high-temperature and high-pressure sterilization and disinfection can be carried out independently without the multispectral LED lamp 140 being required to be disinfected together with the laryngoscope blade 100, and the multispectral LED lamp 140 is prevented from being easily damaged due to high-temperature and high-pressure sterilization and disinfection.
Fig. 3 is a schematic view of the structure of the light pipe of the preferred embodiment of the multispectral switching fiber lighting laryngoscope of the invention. The light guide 130 comprises a narrow tube 131 and a wide tube 132, and a smooth transition semicircular tube 133 is arranged between the narrow tube 131 and the wide tube 132, and the tube of the light guide 130 is narrowed from a light source by a wide to smooth transition, so that the light spectrum emitted by the multispectral LED lamp 140 can be maximally collected and transmitted to the optical fibers in the optical fiber tube 90.
The light guide 130 may be made of Polycarbonate (Polycarbonate) material or Polymethylmethacrylate (PMMA) material having good light guiding property.
