Devices, systems and methods by which the blood pressure, nervous system activity, and neurohornonal activity may be selectively and controllably reduced by activating baroreceptors. A baroreceptor activation device is positioned near a baroreceptor, preferably in the carotid sinus. The baroreceptor activation device may utilize electrodes to activate the baroreceptors. The electrodes may be adapted for connection to the carotid arteries at or near the carotid sinus, and may be designed to minimize extraneous tissue stimulation.

A method is provided for treating respiration conditions of a patient. The method comprises monitoring or measuring a respiration parameter indicative of a need to modify activity of a baroreflex system of the patient, and controlling a baroreceptor activation device to cause or modify activation of a baroreflex response of the patient in response to the monitoring or measuring of the respiration parameter.

Devices, systems and methods are described which control blood pressure and nervous system activity by stimulating baroreceptors. By selectively and controllably activating baroreceptors and / or nerves, the present invention reduces blood pressure and alters the sympathetic nervous system; thereby minimizing deleterious effects on the heart, vasculature and other organs and tissues. A baroreceptor activation device or other sensory activation device is positioned near a dermal bone to provide the treatment.

There is provided an apparatus for use in monitoring the baroreceptor reflex in a user, the apparatus comprising a processor configured to process a signal output by a first sensor that is attached to or located proximate to a bed to determine when the user moves from a lying position on the bed to a sitting position, and to provide an indication of the baroreceptor reflex of the user by processing the signal to determine the change in the heart rate of the user that occurs as a result of moving from the lying position to the sitting position.

The invention relates to a closed in-vitro ventricular drainage apparatus, which comprises two pipelines which are bent in the form of right angles and an analyzer which is arranged outside the pipelines, wherein the two pipelines, which are bent in the form of the right angles, include a first pipeline and a second pipeline; a horizontal part of the first pipeline is connected to a cerebrospinal fluid drainage tube which is close to a ventricular end; a vertical part of the second pipeline is connected to a drainage bag; a vertical part of the first pipeline communicates with a horizontal part of the second pipeline; a piston is arranged in the vertical part of the first pipeline; a spring is connected to the lower surface of the piston; the tail end of the spring is fixedly connected to the bottom of the vertical part of the first pipeline; a baroreceptor is arranged at the inner side of the pipe wall of the vertical part of the first pipeline; the baroreceptor is connected to the analyzer; and capillaries are arranged on the horizontal part of the second pipeline. The closed in-vitro ventricular drainage apparatus provided by the invention can overcome shortcomings in the prior art which adopts open drainage and fails to accurately monitor change in intracranial pressure, and the drainage apparatus is capable of conducting pressure monitoring and heart rate monitoring in vitro and is strong in intuitivity.
