Near infrared imaging is highly complementary to color imaging having a wide range of applications. For example, in health applications, the near infrared can provide biomolecular information on tissue that is not apparent under visual examination nor from the inspection of color images of tissue. Thus, there is utility in viewing both visible color and near infrared images in combination. Described herein are methods to perform visible and near infrared imaging as well as hybrid visible color and near infrared imaging with a single conventional color filter array RGB sensor. The methods automatically provide spatially co-registered color and near infrared images and the methods can be used as the basis for a multispectral or hyperspectral imaging system.

[Solution] This system is for creating dental health examination forms during dental checkups and comprises: a voice recognition function that recognizes findings information input by voice during a visual examination by a dentist; a generation AI unit that structures the findings information recognized by voice recognition; a tooth condition display unit that displays the condition of the teeth in a dental formula by the generation AI unit; and a voice command input unit that receives tooth symptoms input by voice commands from the dentist.

To provide a visual testing tool that enables accurate testing in visual examinations for infants and children, such as the visual examination during the 3-year-old health checkup. [Solution] A visual examination device 1 for use in visual examinations, comprising at least two surfaces, wherein one surface 10 has a target 11 for visual acuity testing, and the other surface 20 has a target 21 for binocular vision testing. Preferably, the target for binocular vision testing is made by attaching alternating strip-shaped images for the right eye and left eye to a lenticular lens, and more preferably, the target for visual acuity testing and the target for binocular vision testing are made such that the testing distance for visual acuity testing using the target for visual acuity testing is the same as the testing distance for binocular vision testing using the target for binocular vision testing, in which case the testing distance is preferably 30 cm to 40 cm.

This invention discloses a pupil parameter measuring instrument and method, including a pupil pen and a back-end analysis and processing platform. The pen's head, middle, and tail are detachably connected. A miniature infrared camera is located at the center of the pen's front end. Several infrared supplementary lights, a visible light source, and a distance sensor are located at the front end of the pen's head. The miniature infrared camera, infrared supplementary lights, visible light source, and distance sensor are all electrically connected to a flexible PCB board. A microcontroller and a motor are located within the middle of the pen, and a display screen is located on the pen's housing. A power module is located within the tail of the pen. The microcontroller is electrically connected to the flexible PCB board, the motor, and the display screen. The pupil pen is connected to the back-end analysis and processing platform via a wireless communication module. This invention provides a pupil parameter measuring instrument and method that effectively reduces the subjective errors caused by traditional visual examination through multi-dimensional quantitative monitoring of pupil diameter, constriction rate, and constriction speed.

The invention discloses a detection device. A reference sighting mark chart and a reference vision value conversion ruler are made by setting a reference sighting mark with a fixed size. A plurality of reference vision values and visual distance values can be measured at the same time by using the reference sighting mark chart and the reference vision value conversion ruler. The reference vision value is a universal five-minute vision value; the visual distant vision value is a direct recorded value of the length value of the distant vision. By applying the detection device, two types of visual values with sufficient quantity can be provided at the same time, the precision and intuition of the visual distance ability detection value are improved, and the higher requirements of visual examination of children and adolescents on the visual measurement range and the recognition of tiny visual change are fully met.

A device suitable for direct visual examination and sample collection from the digestive tract and vagina. The device comprises a main body and an observation channel situated inside the main body comprising a first closed end and a second end. The device further comprises an obdurator for insertion into the main body, the obdurator comprising a longitudinal groove arranged to accommodate the observation channel and a tip comprising a resiliently deformable portion. The resiliently deformable portion is adapted to deform to allow the obdurator to pass over the observation channel as the obdurator is being inserted into the main body and to restore to its original shape once the tip has passed over the observation channel and the obdurator is fully inserted into the main body.

The invention provides a radiolabeled single-stranded DNA probe suitable for early noninvasive diagnosis of lupus nephritis, and belongs to the technical field of detection of systemic lupus erythematosus. The preparation method comprises the following steps: (1) mixing eluted < 68 > GaCl3 and NOTA-A20, reacting, and purifying, so as to obtain < 68 > Ga-A20; and (2) adding the 68Ga-A20 obtained in the step (1) into a buffer solution containing T20 and ssDNA, and carrying out hybridization, so as to obtain the radiolabeled single-stranded DNA probe [68Ga] Ga-NOTA-ssDNA. The radiolabeled single-stranded DNA probe has good kidney targeting and imaging effects in early diagnosis of LN, is expected to provide a safe and accurate non-invasive visual examination means for early diagnosis of LN, and has a good clinical application prospect.

The invention provides an oral mucosa pressure injury detection method. The method relates to the technical field of medical diagnosis and image processing, and comprises the following steps: S1, shooting a to-be-detected oral mucosa by using an endoscope to generate an oral mucosa image, and synchronously acquiring physiological parameters of the oral mucosa through sensing equipment; s2, inputting the oral mucosa image into an image segmentation device, and segmenting a first pressure sore image through the image segmentation device; s3, the first pressure sore image and the physiological parameters are input into an image encoder, and image encoding features and multi-mode sensor encoding features are extracted. The oral mucosa pressure injury detection method thoroughly gets rid of high dependence of traditional visual diagnosis and palpation on clinical experience and traumatic limitation of tissue biopsy, micro injury can be monitored and quantitatively output in the early stage, and an objective and reliable technical means is provided for early discovery and early intervention.
