Technical Field

[0001] The present invention relates to the technical field of spectrum detection equipment, and in particular to a subcutaneous carotenoid detection device based on visible light spectrum. Background Art

[0002] Subcutaneous carotenoids refer to carotenoids that exist under the human skin. They are an important class of natural pigments that are commonly found in the yellow, orange-red or red pigments of animals, higher plants, fungi and algae.

[0003] Human carotenoids are natural antioxidants in the human body. Studies have shown that they can reduce the risks of malignant tumors and cardiovascular and cerebrovascular diseases, and delay all-round aging. In the existing technology, most subcutaneous carotenoid detection devices lack components to provide safety protection for their lenses during use. When they are carried, the lack of safety protection can easily cause damage to the lenses, thereby affecting the detection effect and lacking practicality. Therefore, it is necessary to redesign a subcutaneous carotenoid detection device based on visible light spectroscopy to address the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a subcutaneous carotenoid detection device based on visible light spectroscopy.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A subcutaneous carotenoid detection device based on visible light spectroscopy includes a device body, wherein a fixing plate is fixedly installed on the outer wall of the device body, a protective cover is slidably installed on the bottom wall of the fixing plate through a connecting frame, the outer wall of the protective cover slides through a fixing pin, a dial block is fixedly installed on the outer wall of the fixing pin, and the inner wall of the dial block is connected to the outer wall of the protective cover through a fixing mechanism, a storage groove is provided on the upper end surface of the device body, a handle is rotatably installed inside the storage groove through a connecting mechanism, a slide groove is provided on the outer wall of the device body, two dial plates are slidably installed inside the slide groove through a sliding mechanism, the outer walls of the two dial plates are connected to the inner wall of the slide groove through an elastic mechanism, and the inner walls of the two dial plates are fixedly installed with an insertion rod, and two connecting plates are slidably installed inside the slide groove, and the two insertion rods slide through the connecting plates on the same side respectively, and a shoulder strap is fixedly installed on the ends of the two connecting plates.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] Reference Figure 1-5 A subcutaneous carotenoid detection device based on visible light spectroscopy includes a device body 1, a light shield 2 is fixedly installed on the bottom wall of the device body 1, and the light shield 2 is made of silicone. A fixing plate 3 is fixedly installed on the outer wall of the device body 1, and a protective cover 5 is slidably installed on the bottom wall of the fixing plate 3 through a connecting frame 4. The outer wall of the protective cover 5 slides through a fixing pin 6, and a shift block 7 is fixedly installed on the outer wall of the fixing pin 6. The inner wall of the shift block 7 is connected to the outer wall of the protective cover 5 through a fixing mechanism. The fixing mechanism includes a fixing spring 8 installed on the outer wall of the fixing pin 6, and the two ends of the fixing spring 8 are elastically connected to the outer wall of the protective cover 5 and the inner wall of the shift block 7 respectively.

[0017] A storage slot is provided on the upper end surface of the device body 1, and a handle 10 is rotatably installed inside the storage slot through a connecting mechanism. The connecting mechanism includes a connecting shaft 9 fixedly installed inside the storage slot, and the handle 10 is rotatably installed on the outer wall of the connecting shaft 9. A slide slot is provided on the outer wall of the device body 1, and two dial plates 12 are slidably installed inside the slide slot through a sliding mechanism. The sliding mechanism includes a prismatic rod 11 fixedly installed inside the slide slot, and the two dial plates 12 are slidably installed on the outer wall of the prismatic rod 11. The outer walls of the two dial plates 12 are connected to the inner wall of the slide slot through an elastic mechanism. The elastic mechanism includes a compression spring 13 installed on the outer wall of the prismatic rod 11, and the two ends of the compression spring 13 are elastically connected to the inner wall of the slide slot and the outer wall of the dial plate 12 respectively. The inner walls of the two dial plates 12 are fixedly installed with an insertion rod 14, and two connecting plates 15 are slidably installed inside the slide slot. The two insertion rods 14 slide through the connecting plate 15 on the same side respectively, and a shoulder strap 16 is fixedly installed at the ends of the two connecting plates 15.

[0018] The device body 1 includes the following subsystems: A high-precision light source system with a wavelength of 475nm-480nm and equipped with a control system that can control the emission power, interval and time. In order to control the stability of the emission light source, the operating current is kept at 20mA, such as Figure 6 As shown; Because the excitation wavelength of the emission light source is very wide, in order to prevent the light with a wavelength above 500nm (which can pass through the filter described in b) from interfering with the photodiode, a 500nm cut-off bandpass filter needs to be added, such as Figure 7 As shown; A customized high-pass filter, filtering wavelengths >= 490nm, such as Figure 8 As shown; A high-precision photodiode in a surface-mount ceramic package covered with a filter window (see b); Filtering, storage and Bluetooth communication modules Because biological tissue has a weak light reflection effect and filters out most other wavelengths of light, the resulting photoelectric signal is very weak, so it needs to be amplified. This amplification process will generate a lot of noise interference, so a filter is needed to stabilize the output within a specific range. At the same time, both the sampled and processed data need to be stored and transmitted to the application (mobile phone app) via Bluetooth to display the data and interact with the user. The application interaction module primarily displays test data to users via a UI and can track user historical data, analyze trends, and provide health recommendations. At the same time, with user consent, data is stored in the cloud for further data mining and AI analysis.

[0019] When the present invention is used, the device body 1 adopts a 3.6V 18650 standard battery, the detection head adopts a medical-grade high-precision LED light source, two medium-pass filters with a direct pass rate of more than 95%, and two high-precision photodiodes for calculating the intensity of reflected light after being absorbed by the skin. In addition, the circuit is also equipped with a control unit and a communication module for starting and controlling the detection method. The communication module is used to upload the detection records to the cloud or APP for further analysis and health advice. When the device body 1 is in use, the light shield 2 can be placed close to the skin to block Interference from external visible light. When taking the device body 1, the handle 10 can be rotated by cooperating with the connecting shaft 9, thereby making the handle 10 rotate and extend, and the device body 1 can be taken out by the handle 10. When the device body 1 needs to be carried, the protective cover 5 can be slidably installed inside the connecting frame 4. At this time, the fixing spring 8 can drive the fixing pin 6 to move into the socket, thereby fixing the protective cover 5 to the outer wall of the connecting frame 4, so that the lens of the device body 1 can be safely protected by the protective cover 5 to prevent the lens of the device body 1 from being damaged and affecting the detection effect. When carrying the device body 1, the two shift plates 12 can be first shifted and the compression springs 13 can be pulled, so that the two shift plates 12 can respectively drive the insertion rods 14 on the same side away from the inner wall of the slide groove, and then the two connecting plates 15 can be slid and installed on the outer walls of the insertion rods 14 respectively. At this time, the shift plates 12 can be released, and the two compression springs 13 can restore their deformation and drive the shift plates 12 to move and reset, so that the two insertion rods 14 can fit into the inner wall of the slide groove, and the connecting plates 15 can be fixedly installed inside the slide groove, so that the device body 1 can be conveniently carried through the shoulder strap 16.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
