Detailed Description
Exemplary embodiments that embody features and advantages of the present invention will be described in detail in the following description. It will be understood that the invention is capable of various modifications in various embodiments, all without departing from the scope of the invention, and that the description and illustrations herein are intended to be by way of illustration only and not to be construed as limiting the invention.
For the purpose of further illustrating the principles and structure of the present invention, preferred embodiments of the invention will now be described in detail with reference to the accompanying drawings.
Referring to fig. 1 to 3, the present invention provides a percutaneous jaundice apparatus 1, comprising: a light source device 11, a lens 13, and a light source driving circuit 12. The light source device 11 includes a device body 111, a light source board 112 provided in the device body 111, a blue LED light source 113 and a green LED light source 114 provided on the light source board 112, and a receiving fiber 115 penetrating the light source board 112. One end of the device body 111 is a perspective window for transmitting the light emitted by the blue LED light source 113 and the green LED light source 114 and the reflected light of the skin. The light source driving circuit 12 is a constant current driving circuit, and drives the blue LED light source 113 and the green LED light source 114 on the light source board 112 to emit light. According to the invention, the blue light LED light source 113, the green light LED light source 114 and the receiving optical fiber 115 are integrated in the light source device 11, so that the incident optical fiber is omitted, the design difficulty and the cost of the percutaneous jaundice instrument 1 are reduced, discomfort of eyes caused by strong light in the flash moment can be effectively avoided, and eye damage caused by direct irradiation is avoided. And constant current driving is adopted, so that the stability and consistency of the brightness of the light source are ensured, and the measurement error caused by the fluctuation of the light source is avoided.
Preferably, the blue LED light sources 113 and the green LED light sources 114 are alternately distributed in a ring shape around the receiving optical fiber 115. Specifically, in the present embodiment, the light source plate 112 is a circular plate, and the blue LED light sources 113 and the green LED light sources 114 are four pairs, alternately distributed in a ring shape. In other embodiments, the light source board 112 may be square, hexagonal or irregular, and may be set according to practical needs. The number of the blue LED light sources 113 and the green LED light sources 114 may be two pairs, three pairs or other numbers, and may be set according to actual needs.
The blue LED light source 113 is a light source having a half-width of 10nm centered at a wavelength of 460nm, and the green LED light source 114 is a light source having a half-width of 10nm centered at a wavelength of 550 nm. By adopting the design, the interference of other wavelength light sources can be avoided, the accuracy of the instrument is improved, and the damage of ultraviolet rays to the skin can be avoided. And the blue light LED light source 113 and the green light LED light source 114 have low working voltage, low power consumption, stable performance, long service life and small volume.
The receiving optical fiber 115 includes a hermetic case and an optical fiber provided inside the hermetic case. To eliminate interference of external light with the receiving fiber 115, the inner wall of the hermetic case is coated with a black layer, which absorbs the external light reaching the inner wall of the hermetic case.
The percutaneous jaundice instrument 1 further comprises a lens 13. The lens 13 is detachably connected to the light source device 11. In this embodiment, the percutaneous jaundice instrument 1 is used with the lens 13, and in other embodiments, the lens 13 may not be required to be used alone.
The lens 13 includes a cylindrical body 131 having both ends open, and a polarizer 132 and an analyzer 133 provided at one end of the cylindrical body 131, the polarizer 132 covering and attaching to the see-through window, the analyzer 133 opposing the receiving optical fiber 115 and the analyzer 133 covering and attaching to the end face of the receiving optical fiber 115.
Specifically, in the present embodiment, the polarizer 132 and the analyzer 133 are located on the same plane and concentric. The polarizer 132 allows light having a vibration direction on the same plane as the vibration direction of the polarizer 132 in the incident light to pass therethrough, and the passed light is called polarized light. The analyzer 133 allows polarized light in accordance with the direction of the transmitted vibration of the polarizer 132 to pass therethrough. The light rays pass through the polarizer 132 to form polarized light with a specific angle, after the polarized light irradiates the skin of a human body, part of the polarized light enters the analyzer 133 after being reflected by the epidermis, and part of the polarized light enters the subcutaneous tissue to enter the analyzer 133 after being reflected and refracted. In this embodiment, the vibration transmission direction of the analyzer 133 is designed to be perpendicular to the vibration transmission direction of the polarizer 132, that is, the angle between the vibration transmission direction of the polarizer 132 and the vibration transmission direction of the analyzer 133 is 90 degrees. Therefore, the light reflected by the epidermis cannot pass through the analyzer 133 because the vibration direction is 90 degrees to the polarization transmission direction of the analyzer, and thus cannot enter the receiving fiber 115 to be detected, but the light reflected by the subcutaneous tissue cannot enter the receiving fiber 115 to be detected because the vibration direction is not 90 degrees to the polarization transmission direction of the analyzer, and thus can enter the analyzer 133 to be detected. In other embodiments, the included angle between the vibration transmission direction of the polarizer 132 and the vibration transmission direction of the analyzer 133 may be other angles, which may be set according to practical needs. The polarizer 132 and the analyzer 133 are provided by adopting a polarized light technique, so that reflected light from the surface of the skin is eliminated, the difference between blue light and green light for calculating bilirubin in blood is increased, and the accuracy and precision of a calculation result are improved.
In order to adjust the included angle between the vibration transmission direction of the polarizer 132 and the vibration transmission direction of the analyzer 133 to 90 degrees, one of the polarizer 132 and the analyzer 133 is fixed, and the other is rotatably adjustable about an axis. In this embodiment, the analyzer 133 is fastened to the receiving fiber 115, and the polarizer 132 is rotatably adjusted about the axis. In other embodiments, the polarizer 132 may be fastened to the apparatus body 111, and the analyzer 133 may be rotatably adjusted about an axis and set as needed.
Preferably, the inner wall of the cylindrical body 131 is coated with a black layer in order to prevent light not reflected through the skin from entering the analyzer 133. When the light is reflected to the inner wall of the cylindrical body 131, the black layer absorbs the light, and does not continue to reflect as much as other colors (not black) so that the light passes through the analyzer 133 and enters the receiving fiber 115, resulting in inaccurate detected reflected light and measurement errors.
In order to reduce the interference of external light and thus the inaccuracy of the detection data, the lens 13 tapers away from the light source device 11.
Referring to fig. 4, the percutaneous jaundice apparatus 1 of the present invention operates as follows: the percutaneous jaundice instrument 1 contacts the skin and presses to start the test, the blue LED light source 113 and the green LED light source 114 on the light source device 11 emit light, the light reaches the polarizer 132, and polarized light transmitted through the polarizer 132 reaches the skin. Some polarized light enters the analyzer 133 after being reflected by the epidermis, some polarized light enters the subcutaneous tissue and enters the analyzer 133 after being reflected and refracted, and the analyzer 133 only allows the light reflected by the subcutaneous tissue to enter the receiving optical fiber 115, because the vibration direction of the light reflected by the subcutaneous tissue and the vibration transmission direction of the analyzer do not form 90 degrees, the light can pass through. The light reaching the receiving optical fiber 115 enters the optical filter 15 (460 nm optical filter and 550nm optical filter) according to the ratio of 50:50 through the spectroscope 14, is irradiated to enter the photoelectric conversion circuit 16 to be converted into an electric signal, and then is converted, acquired, processed and analyzed through the A/D conversion 171 and the MCU172 of the data processing system to calculate the percutaneous bilirubin concentration (TCB), the total serum bilirubin concentration (TSB) is estimated based on the percutaneous bilirubin concentration (TCB), and the measured result is displayed on the display screen 18. The percutaneous jaundice instrument 1 can rapidly and accurately detect the bilirubin concentration of the neonate, and reduce the risk of the neonate suffering from the illness.
The specific structure and arrangement of the beam splitter 14, the optical filter 15, the photoelectric conversion circuit 16, the a/D conversion 171, the mcu172, the display 18, and the like are described in the prior art, and will not be described in detail herein.
According to the technical scheme, the invention has the advantages and positive effects that: according to the invention, the blue light LED light source, the green light LED light source and the receiving optical fiber are integrated in the light source device, and the light emitting surfaces of the blue light LED light source and the green light LED light source directly face the perspective window to emit light outwards, so that the incident optical fiber is omitted, the design difficulty and the percutaneous jaundice instrument cost are reduced, discomfort of eyes caused by intense light in flash moment can be effectively avoided, and eye damage caused by direct irradiation is avoided. And constant current driving is adopted, so that the stability and consistency of the brightness of the light source are ensured, and the measurement error caused by the fluctuation of the light source is avoided.
The foregoing is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structural changes made by applying the descriptions and the drawings of the present invention are included in the scope of the present invention.
