摘要： A subcutaneous sensor for use with a continuous glucose monitor includes a reference electrode, a working electrode, and a composition for releasing nitric oxide (NO). The reference electrode includes a reference substrate and an ion limiting layer over the reference substrate. The working electrode includes a conductive substrate, an interference layer over the conductive substrate, an enzyme layer over the interference layer, and a glucose limiting layer. The enzyme layer has an enzyme for reacting with in-vivo glucose in body fluid of a patient. The glucose limiting layer is over the enzyme layer and limits an amount of the in-vivo glucose from the body fluid of the patient that passes to the enzyme layer. The composition for releasing nitric oxide (NO) includes a NO release compound, a hydrophilic material and a hydrophobic material. The composition is on the reference electrode.

摘要： A chest non-invasive blood pressure detecting probe based on pulse wave transit time and a device thereof are provided. The detecting probe is attached closely to the skin surface of the human chest, and includes a probe body and a patch, which are of split type. The patch is attached and mounted, in a male-female fastener form, on the probe body for use, so that when the patch needs to be replaced, the patch is directly removed and replaced with a new patch, which is convenient for use. The detecting probe is portable and used for continuous dynamic real-time acquiring of the human aortic blood pressure, which is free from the constraints of lead wires, small and comfortable, and high in measuring precision.
