Continuous fluid monitoring system

A method for measuring an intracranial fluid in a patient's head, after treatment of an occlusion of a blood vessel supplying the patient's brain, the method comprising:

• securing a volumetric integral phase-shift spectroscopy (VIPS) device to the patient's head;
• measuring the intracranial fluid with the VIPS device by measuring a phase shift between a magnetic field transmitted from a transmitter on one side of a VIPS device and a magnetic field received at a receiver on another side of the VIPS device, at one or more frequencies;
• and
• determining, with the processor, whether the treatment affected the occlusion.

A volumetric integral phase-shift spectroscopy (VIPS) device for measuring an intracranial fluid in a patient's head, the device comprising:

• a frame, comprising:
• a front portion comprising a housing, wherein the housing includes a display;
• two arms extending from opposite ends of the front portion;
• and
• two wrap-around ends, configured to wrap around the back of a patient's head and over the ears;
• at least one registration feature coupled with the frame for facilitating registration of the VIPS device with the patient's head;
• at least one receiver housed within the housing;
• a first transmitter in one of the two wrap-around ends of the frame;
• a second transmitter in the other of the two wrap-around ends of the frame, wherein the first and second transmitters and the at least one receiver are configured to measure at least one of multiple phase shifts or multiple amplitudes in the intracranial fluid;
• and
• a processor in the housing, configured to receive data from the at least one receiver and process the data to generate display data describing the intracranial fluid for displaying on the display of the housing of the VIPS device.

A method for measuring a change in an intracranial fluid volume in a patient's head, the method comprising:

• securing a volumetric integral phase-shift spectroscopy (VIPS) device to the patient's head;
• measuring a fluid volume with the VIPS device;
• and
• measuring a cyclical change in amplitude of the fluid volume.

A volumetric integral phase-shift spectroscopy (VIPS) device for measuring an intracranial fluid volume in a patient's head, the device comprising:

• a headband configured to fit circumferentially around the patient's head;
• a VIPS receiver attached to a front of the headband;
• circuitry attached to the headband and the VIPS receiver;
• a first VIPS transmitter attached to the headband apart from the VIPS receiver;
• a second VIPS transmitter attached to the headband apart from the VIPS receiver and the first VIPS transmitter, wherein the first and second VIPS transmitters and the VIPS receiver are configured to measure at least one of multiple phase shifts or multiple amplitudes in the fluid volume in the patient's head;
• and
• a processor coupled with the headband and the circuitry and configured to determine that at least one of the multiple phase shifts or the multiple amplitudes is indicative of an occlusion of a blood vessel.
