The invention provides a plateau hypoxic encephaledema early warning system, which comprises a first acquisition module configured to emit ultrasonic waves to at least two tangent planes of a first area to obtain an ultrasonic image reflected after being transmitted by an eyeball, and determining the diameter of an optic nerve sheath after first preprocessing; the second acquisition module is configured to emit a near-infrared signal source to a second area to obtain a spectral image reflected after transcranial transmission, and absorption spectrums of oxyhemoglobin and deoxidized hemoglobin are obtained after second preprocessing; the data processing module is configured to obtain the optic nerve sheath diameter and the absorption spectrum and determine a first influence factor and a second influence factor about the optic nerve sheath diameter and the absorption spectrum; and the early warning module is configured to give an alarm if the first influence factor and the second influence factor exceed a preset threshold value under a first preset condition. Early warning and monitoring of encephaledema are achieved through multi-mode monitoring.

The invention discloses a low-oxygen affinity deoxidized hemoglobin spray and application thereof. The invention creatively discovers that the oxygen concentration on the surface of a wound is obviously higher than that of pure deoxidized hemoglobin and high-oxygen-affinity deoxidized hemoglobin with higher oxygen carrying capacity after the low-oxygen-affinity deoxidized hemoglobin with higher oxygen release capacity is used; it is proved that the low-oxygen affinity deoxidized hemoglobin is more beneficial to improvement of the oxygen concentration of the wound surface. According to the specific embodiment of the invention, the RSR-13 is combined with the deoxidized hemoglobin, the conformation of the deoxidized hemoglobin is changed, the oxygen affinity of the deoxidized hemoglobin is reduced, the oxygen release of the deoxidized hemoglobin in the hypoxia tissue is effectively enhanced, the drug has no obvious toxicity to skin cells, the effectiveness and safety of the drug in skin wound treatment are improved, and the application prospect is wide. The method is suitable for treating multiple types of wound surfaces, and has wide application value and market prospect.

This application discloses an endoscopic image processing method based on blood oxygen saturation and multi-center wavelength, relating to the field of medical image processing. The method includes acquiring a first initial image signal, a second initial image signal, a third initial image signal, and a fourth initial image signal; calculating oxyhemoglobin concentration information at a target site based on the second and third initial image signals; calculating deoxyhemoglobin concentration information at the target site based on the second and fourth initial image signals; calculating blood oxygen saturation at the target site based on the oxyhemoglobin and deoxyhemoglobin concentration information; enhancing the brightness of the second initial image signal based on the blood oxygen saturation to obtain a second enhanced image signal; and generating a target image based on the second enhanced image signal, the first initial image signal, and the third initial image signal. The target image is used to identify the bleeding location at the target site.
