4 results about "Oxygen deprivation" patented technology

This invention discloses an automatic oxygen supply device for emergency department nursing and its usage method, relating to the field of medical device technology. It includes an oxygen supply device with a hospital bed on one side. The inner side of the oxygen supply device has a first cavity and a second cavity. An oxygen cylinder is installed inside the first cavity, and a connecting pipe is installed at the output end of the oxygen cylinder. The connecting pipe passes through the first cavity and extends to the top of the hospital bed, where an oxygen mask is fixedly connected. This invention, by setting a connecting mechanism, connects the hospital bed and the oxygen supply device, thereby solving the industry pain point of traditional transport where the oxygen supply device and the hospital bed are not synchronized and require separate pushing by a dedicated person. It enables the oxygen supply device to move synchronously with the hospital bed throughout the entire transport process, ensuring uninterrupted oxygen therapy during patient transport and eliminating the risk of oxygen deprivation during transport.

This invention provides a drug delivery system and its application based on brain microvascular endothelial cells, comprising stimulated brain microvascular endothelial cells, wherein the stimulation is performed by culturing in a culture system containing supernatant of brain microvascular endothelial cells cultured under glucose and oxygen deprivation. This invention solves the problems of targeting and timeliness in treating blood-brain barrier damage after ischemic stroke under current technologies. It can regulate the BBB while supporting its function and structure, maintaining and repairing BBB function after reperfusion, thus improving the prognosis of stroke treatment. The cell preparations in this invention are widely available and easily obtained, and can rapidly repair the blood-brain barrier. Furthermore, the cell preparations in this invention can target ischemic brain sites and can be administered via simple intravenous injection, facilitating clinical operation.
