Methods and systems monitor and assess brain bioimpedance through the use of an ocular window that assesses dynamic changes in cerebral blood volume (CBV). That ocular window is implemented through an ocular bioimpedance device that, in a non-invasive manner, measures numerous different brain health indicators using the bioimpedance measurements collected through the regions around the eyes. The ocular bioimpedance device may be goggles with localized measurement electrodes that include cathodes and anodes.

Infusion pumps having a fluid pump and a processor are disclosed. The processor is configured to transmit a signal to make a medical facility network aware that the infusion pump is within a wireless network range of a medical treatment area of a medical facility, receive a request for device identity information specific to the infusion pump, transmit the device identity information specific to the infusion pump, receive, if the infusion pump is authenticated by the medical facility network, an initialization signal from the medical facility network, wherein the initialization signal causes initialization of the infusion pump within the medical treatment area, receive, from a sensor via the medical facility network after receiving the initialization signal, a measurement, and control the adjustable rate of the fluid pump based at least in part on the measurement. Systems having infusion pumps are also disclosed.

Novel tools and techniques for assessing, predicting and/or estimating effectiveness of hydration of a patient and/or an amount of fluid needed for effective hydration of the patient, in some cases, noninvasively.

A multi-sensor system may include a catheter that has lumen, is flexible, is made of a polymer, and has a circular cross section that has an outer diameter of no more than 0.5 cm; and one or more sensors that sense multiple characteristics of material flowing within the lumen, including at least two of the following: flow rate, pressure, and composition of the material.

A subdural sensor includes: a substrate formed of a flexible material; and at least one type of sensor part mounted on the substrate. The substrate has an elongated shape, and includes: a sensor area in which the sensor part is mounted and a wiring pattern connected to the sensor part is formed; a wiring area contiguous with the sensor area, the wiring pattern extending in the wiring area; and a connector area contiguous with the wiring area, the connector area being an area on which a connector to be connected to the wiring pattern extending from the wiring area is mounted. A tip part of the sensor area has a planar shape that curves convexly toward an outer periphery, and a side shape that curves toward a first surface, the first surface being on the side of a dura mater when the subdural sensor is inserted into the subdural space.

Brain drainage device having a rod-shaped hollow body with an inner drainage channel for insertion through the cranium into the brain, a first sensor arrangement with at least one sensor for measuring a physical parameter, and a signal interface; wherein the rod-shaped hollow body has a first region A which, in the applied state, is designed to protrude into the ventricle situated in the brain; wherein the rod-shaped hollow body has a second region B, which is arranged proximally from the first region, wherein the second region is designed to lie in the region of the brain mass in the applied state; wherein the first sensor arrangement is arranged in the second region in order to measure a physical parameter of the brain mass; wherein the first sensor arrangement is connected to the signal interface such that measurement data determined by the first sensor arrangement are transmitted to a measuring system that is to be connected.

Described herein are systems, devices, and methods for remote assessment and correction of baseline pressure instability of medical pressure sensors. The present disclosure enables centralized surveillance of baseline pressure instability, which provides a technical solution for manufacturers of pressure sensors and/or pressure transducer systems to monitor the proper function of their products. Moreover, health care personnel are provided with means to assess pressure sensor instability and get corrected pressure scores, neither of which are presently unavailable. The disclosure thereby provides a technical solution to a problem of medical pressure sensors that represents risk of harm to patients.

Apparatus for the diagnostics and treatment of conditions presenting as intracranial circulation maladies in reliance upon segmental intracranial compartment pressure, which is established from the interdynamics between intra-cranial and extra-cranial circulation, and which relies upon compression of the extra-cranial vascular network in order to: measure cranial inflow and outflow pressure in the intra-extra cranial collateral (e.g., in the network supplied by the supraorbital artery), to estimate intracranial compartment segmental perfusion pressure; temporarily augment intracranial inflow pressure during a period of the compromise (e.g., common carotid cross-clamp during carotid endarterectomy or extracranial stenosis with low-flow state) and redirect extracranial blood-flow intracranially to augment cerebral circulation and/or introduce therapeutic agents or cold blood to the intracranial compartment.
