The invention relates to a multi-mode eye-brain collaborative maintenance intelligent device, and belongs to the technical field of eye-brain nursing equipment.The device is provided with an impression stimulation module, the impression stimulation module stimulates mild energy of an impression acupoint, the mild energy can be directly conducted to a paranasal sinus olfactory bulb in the deep part of a nasal cavity, the area is the starting end of paranasal sinus nerves, the paranasal sinus nerves are branches of cranial nerves, and therefore the paranasal sinus acupoint can be stimulated; the neural pathway directly extends to brain hippocampus, brain marginal tissue, pituitary gland and other core structures related to neuronutrition and brain metabolism; after stimulation, the paranasal sinus olfactory bulb and paranasal sinus nerves are activated to form a neural pathway for targeted delivery of the atomized liquid, so that the atomized particles of the brain care liquid are adsorbed on the surface of the paranasal sinus olfactory bulb and permeate into the brain along the activated neural pathway, and meanwhile, the permeability of the blood brain barrier is improved, so that the delivery resistance of the atomized liquid to related functional areas of the brain is further reduced, and the targeted delivery of the atomized liquid is realized. Precise nutrition for cranial nerves is achieved, and the problem that brain maintenance is invalid due to the fact that conventional nasal cavity atomized liquid enters the lung is thoroughly solved.

Provided are drug-device combinations and methods used for direct delivery of therapeutic drugs to the pituitary gland, wherein the drug-device combination also acts as a barrier between a sella turcica (pituitary fossa) and a sphenoid sinus to effectively trap or confine the drug substance within the sella turcica to prevent its premature escape away into the CSF from the target pituitary; thereby reducing or eliminating systemic toxicity of the drug substance. The drug-device combination includes a cap, a stem, a drug that is therapeutically effective for a pituitary gland disorder.

A method and apparatus for manipulating a temperature set-point of a human or homeothermic-animal for increasing or decreasing the body temperature above or below the prevailing body temperature for therapeutic purposes. The method includes the steps of warming or cooling sphenoid sinuses externally resulting in manipulation of the temperature of the pituitary gland which in turn results in manipulation of the body-temperature set-point and the body temperature manipulates accordingly to the new temperature set-point. A heat exchange medium can be used to warm or cool sphenoid sinuses and thus the pituitary gland. The heat exchange fluid can be liquid, or gas maintained at a predetermined temperature. Alternatively, a temperature-controlled probe can be used that upon contact with the sphenoid sinuses provides for the heat exchange.

The present invention relates to the technical field of medical devices, and particularly relates to a portable head-mounted pituitary gland stimulation device, which includes an elastic band, a mounting disc, and a cooling member. During the process of the spiral wire generating a magnetic field, heat will be generated. According to the position setting of the turbulence tube in the cooling member, when the turbulence fan blades rotate, the gas in the turbulence tube forms an air flow along the axis of the turbulence tube. After the gas in the turbulence tube flows, a pressure difference is formed inside and outside the turbulence tube, so that the gas exchanges on both sides of the turbulence tube through a plurality of circulation ports. When the gas flows through the spiral wire, the gas absorbs the heat generated when the spiral wire works. During the gas circulation process, the heat of the spiral wire is evenly distributed throughout the installation cavity, and the heat in the installation cavity is dissipated outward through the side walls of the installation box, thereby reducing the temperature when the spiral wire works.

The invention relates to the technical field of microorganisms, in particular to a probiotic composition for relieving anxiety and application, and the probiotic composition comprises lactobacillus rhamnosus LGD-0817, lactobacillus rhamnosus LDL-1708, lactobacillus plantarum LEP-1208 and lactobacillus plantarum MCA-3066. The probiotic composition is used for fermenting the traditional Chinese medicine composition, the obtained traditional Chinese medicine fermentation composition contains probiotics and traditional Chinese medicine fermentation liquor, the probiotics and the traditional Chinese medicine fermentation liquor can effectively achieve a synergistic effect, and the medicine effect of improving and treating depression is achieved; the traditional Chinese medicine fermentation composition plays a role through a plurality of ways, on one hand, the CRF content of hypothalamus and the ACTH content secreted by pituitary are reduced, so that the level of serum corticosterone is regulated and controlled, and the anti-depression and anti-anxiety effects are achieved; on the other hand, the 5-HT level of the central nervous system can be increased, the anti-depression effect is achieved, and it is prompted that the compound has the prospect of developing new anti-depression and anti-anxiety drugs and has clinical practical value.

A method and apparatus for manipulating a temperature set-point of a human or homeothermic-animal for increasing or decreasing the body temperature above or below the prevailing body temperature for therapeutic purposes. The method includes the steps of warming or cooling sphenoid sinuses remotely resulting in manipulation of the temperature of the pituitary gland without manipulation of the hypothalamus temperature which in turn results in manipulation of the body-temperature set-point and the body temperature manipulates accordingly to the new temperature set-point. A heat exchange medium can be used to warm or cool sphenoid sinuses and thus the pituitary gland. The heat exchange fluid can be liquid, or gas maintained at a predetermined temperature. Alternatively, a temperature-controlled probe can be used that upon contact with the sphenoid sinuses provides for the heat exchange.
