A method of and a device for non-invasively measuring the neurological depressed state and the hemodynamic state of a human patient and involving steps and units of non-invasively measuring EEG, cardiac cycle period, electrical-mechanical interval, mean arterial pressure, and ejection interval and converting the EEG into a neurological index as well as converting the measured electrical-mechanical interval, mean arterial pressure and ejection interval into the cardiac parameters such as Preload, Afterload and Contractility, which are the common cardiac parameters used by an anesthesiologist. A general anesthetic is administered based upon the converted neurological index. A vasoactive agent is independently administered based upon the converted cardiac parameters as necessary in order to restore cardiovascular homeostasis in the patient. The converted neurological and hemodynamic state of a patient are displayed on a screen as an index value and a three-dimensional vector with each of its three coordinates respectively representing Preload, Afterload and Contractility. Therefore, a medical practitioner looks at the screen and quickly obtains the important and necessary information.

A female stimulation device comprising a resilient device body having a partially deformable tip portion, a flange and an intermediate side wall portion extending outwardly from the tip portion to the flange. In use, the tip portion is compressed to force air out of the device body and the flange is placed in contact with vaginal wall tissue so that the clitoris is encompassed by the device body. Release and restorative deformation of the tip portion causes a partial vacuum within the device body, which maintains the device in place and provides suction to the clitoris. The intermediate side wall portion is substantially non-deformable in response to deformation of the tip portion, as may be achieved with outwardly convex side walls, thereby preventing deleterious entrapment and compression of the clitoris. Pharmacologically active materials, such as vasoactive agents, substances, and medications, may be applied to the device for contact with the clitoris during use in order to further enhance female sexual function.
