Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a nail fold microcirculation and blood oxygen two-in-one detector, more specifically, to a portable finger-clip nail fold microcirculation and blood oxygen two-in-one detector. Background Art

[0002] Microcirculation refers to the blood circulation between arterioles and venules in the body. It is the place where tissue cells and blood exchange substances. Its functional state can reflect the health status of various organs in the body. Therefore, microcirculation images can assist doctors in judging or diagnosing the health status or condition of the person being collected.

[0003] The epidermis of the nail fold is thin, and the microvessels here are easy to observe under a microscope. It is currently one of the most commonly used sites for observing microcirculation. However, the nail fold microcirculation detectors currently used on the market are basically stage-type. After the subject places his finger on the stage, the debugger adjusts the subject's finger position and the distance between the microscope and the subject's nail fold according to the nail fold microcirculation image displayed on the screen. This process is cumbersome and time-consuming. It is generally difficult for the subject to complete it alone. In addition, due to the fixed size of the stage, the nail fold microcirculation detector is often difficult to move or inconvenient to carry.

[0004] In addition, the nail fold microcirculation detectors currently on the market can often only achieve the single function of capturing nail fold microcirculation, and are not combined with other related auxiliary diagnostic functions, failing to better realize the diagnostic analysis of an individual's overall condition through nail fold microcirculation detection. Utility Model Content

[0005] The utility model aims at the problems and shortcomings of the prior art and provides a novel portable nailfold microcirculation and blood oxygen two-in-one detector, which is easy to carry and can monitor the body's blood oxygen and pulse while capturing nailfold microcirculation images, thereby reflecting the body's health status in real time.

[0006] The utility model solves the above technical problems through the following technical solutions:

[0007] The utility model provides a portable nail fold microcirculation and blood oxygen two-in-one detector, characterized in that it comprises an upper shell and a lower shell, the rear end of the upper shell and the rear end of the lower shell are connected by a rotating shaft, the upper surface of the lower shell is provided with a lower concave portion for fitting the curvature of the finger pulp, the lower surface of the front part of the upper shell is provided with an upper concave portion for fitting the curvature of the finger back, and the front end of the upper shell and the front end of the lower shell together form an arc-shaped opening;

[0008] A red light and infrared light transmitter is fixed at the front inner portion of the upper shell and directly above the upper recessed portion, a receiver is fixed at the front inner portion of the lower shell, the red light and infrared light transmitter and the receiver are arranged opposite to each other to form a blood oxygen detection group, a camera assembly is fixed at the rear inner portion of the upper shell, a small protrusion directly below the camera assembly is fixed on the rear portion of the lower recessed portion of the lower shell, a PCB board is fixed in the upper shell, a main control chip is integrated on the PCB board, a display screen and a detector switch control key are embedded on the upper surface of the upper shell, and the red light and infrared light transmitter, receiver, camera assembly, display screen and detector switch control key are all electrically connected to the main control chip.

[0009] The utility model designs a portable nailfold microcirculation and blood oxygen two-in-one detector, which relies on the small cylindrical protrusion on the upper surface of the lower shell to achieve the initial positioning of the finger to be measured, eliminating the cumbersome steps of finger positioning of the traditional nailfold microcirculation detector, and the utility model is a finger-clip type, with excellent wrapping and fixation, eliminating the heavy loading platform, and achieving the purpose of portability.

[0010] In addition, the utility model can monitor the subject's own blood oxygen and pulse while the subject detects the nailfold microcirculation image by himself, and combines the nailfold microcirculation image with the real-time blood oxygen pulse to realize the diagnosis and analysis of the individual's overall health status.

[0011] The utility model does not improve the principle of detecting nail fold microcirculation images and the principle of blood oxygen detection, but improves the structure of the detector from a stage type to a finger clamp type, which makes finger positioning simple and adds a blood oxygen detection structure.

[0027] The main control chip 19 adopts an STM32 series single-chip microcomputer. According to the functions of each port pin of the STM32 series single-chip microcomputer, it is a conventional setting for technicians in this field to determine which specific port pin of the STM32 series single-chip microcomputer is electrically connected to each electronic device (red light and infrared light transmitter 13, receiver 14, autofocus camera 82, ring lighting 83, display screen 15, Bluetooth switch control key 16, detector switch control key 17, magnification and reduction control key 18, Bluetooth module 20 and flash memory 21).

They are all existing structures. The specific structures, circuit designs and working principles of the red light and infrared light transmitter 13, receiver 14, autofocus camera 82, ring light 83, display screen 15, Bluetooth switch control key 16, detector switch control key 17, magnification and reduction control key 18, Bluetooth module 20, flash memory 21 and main control chip 19 are all publicly available prior arts.

Press the Bluetooth switch control key 16 to turn on Bluetooth, the main control chip 19 receives the Bluetooth switch signal, starts the Bluetooth module 20, and the detector and the host computer are wirelessly connected through Bluetooth. The red light and infrared light transmitter 13 emits red light and infrared light respectively, and the receiver 14 receives the red light and infrared light passing through the user's finger. The main control chip 19 transmits the transmission signal emitted by the red light and infrared light transmitter 13 and the reception signal received by the receiver 14 to the host computer through the Bluetooth module 20. The host computer obtains the user's blood oxygen data and pulse data based on the transmission signal and the reception signal. The user can see the blood oxygen data and pulse data on the host computer, and can also see the blood oxygen data and pulse data on the display screen 15. After the ring lighting 83 starts working, it provides appropriate lighting for obtaining the nail fold microcirculation image, the transparent light cover 84 converges the light just above the nail fold, and the autofocus camera 82 automatically focuses to obtain the nail fold microcirculation image. According to the nail fold microcirculation image displayed on the display screen 15, the user can press the magnification or reduction control key 18 to adjust the magnification or reduction ratio of the nail fold microcirculation image to obtain a suitable and clear nail fold microcirculation image.
