In one aspect, a portable medical treatment and guidance apparatus for assisting a caregiver in evaluating and treating a patient experiencing a medical emergency according to a time sensitive prioritization of the medical emergency is provided. The portable medical treatment and guidance apparatus includes a housing having at least one compartment; a plurality of medical supplies housed within the at least one compartment; a user interface configured to receive input and provide an interactive query flow for assisting the user in providing medical treatment; and at least one processor and memory communicatively coupled to the user interface. The at least one processor and memory is configured to determine instructions for assisting the caregiver in treating the patient and present, via a user interface, the determined instructions to assist the caregiver in treating the medical emergency.

A method of identifying and locating tissue abnormalities in a biological tissue includes irradiating an electromagnetic signal, via a probe defining a transmitting probe, in the vicinity of a biological tissue. The irradiated electromagnetic signal is received at a probe, defining a receiving probe, after the signal is scattered/reflected by the biological tissue. Blood flow information pertaining to the biological tissue is provided. Based on the received irradiated electromagnetic signal and the blood flow information, tissue properties of the biological tissue are reconstructed. A tracking unit determines the position of at least one of the transmitting probe and the receiving probe while the step of receiving is being carried out, the at least one probe defining a tracked probe. The reconstructed tissue properties are correlated with the determined probe position so that tissue abnormalities can be identified and spatially located.

Improved optical coherence tomography systems and methods to measure thickness of the retina are presented. The systems may be compact, handheld, provide in-home monitoring, allow the patient to measure himself or herself, and be robust enough to be dropped while still measuring the retina reliably.

A device configured to provide a faster and more accurate measurement of depths of holes for placement of bone screws and fastener for bone implant fixation procedures. The device includes a combination of a bone probe for physical examination of a hole drilled in a bone and a depth gauge member for determining a depth of the hole and providing digital measurement of the depth.

An insert assembly, insertable in a handpiece of a medical device, has an insert having an insert metal tang, a ferromagnetic layer in contact with the insert metal tang, a dielectric layer in contact with the ferromagnetic layer, an insert antenna in contact with the dielectric layer, having an insert antenna metal element and configured to receive and transmit electromagnetic fields, and an identification chip operatively connected to the insert antenna and configured to transmit information about the insert assembly. The ferromagnetic layer reduces or cancels attenuation and/or distortion phenomena of an electromagnetic field caused by parasitic effects due to interaction of a transmitted or received electromagnetic field with metal parts of the insert metal tang, liquids present in the insert, and the insert antenna metal element. The ferromagnetic layer dielectric layer and insert antenna form a transceiver device putting the identification chip in communication with a handpiece antenna.

Systems and methods for evaluating neurologic function of a subject are described. An odorant, auditory and/or somatosensory generator is configured to deliver a sensory stimulation to the subject, a plurality of electrodes are configured to be attached to the subject, and a handheld EEG control unit is configured to control the odorant, auditory and/or somatosensory generator, process the neural signals from the plurality of electrodes and generate an assessment of neurologic function of the subject.

A system for generating an overdose risk score of a user includes a physiological sensor coupled to a wearable device and configured to detect attenuated light from a tissue site of the user and at least one hardware processor. The hardware processor can be configured to determine a plurality of parameters based on the attenuated light, determine a baseline risk, an instability index, an average slope, and desaturation pressure, and determine a weighted aggregate of the baseline risk, the instability index, the average slope, and the desaturation pressure for each of the plurality of parameters, determine an overdose risk score by determining a weighted aggregate of the plurality of parameters, determine an alarm level of a series of escalating alarm levels based on the overdose risk score, and implement intervention associated with the determined alarm level.

The guiding and assessment system for cervical examination of gravid patients relates to devices, systems, and methods for use as educational and non-medical intervention facilitation tools for both medical professionals and gravid patients/persons having a baby to achieve a vaginal delivery through non-medical interventions such as position change, gravity positions, massage, pelvic mobility, etc. by assessing the presentation of the fetal head to the maternal pelvis, dilation, and effacement. To accomplish this, the system includes a portable device for measurement of cervical dilation, presentation of fetal position relative to the maternal pelvis, and/or measurement of effacement of the cervix in a gravid patient. The device includes semicircular open rings made of pliable material, as well as a plurality of dilation markings, a plurality of effacement markings, and a plurality of presentation markings, that represent measurements of cervical dilation, effacement and fetal head presentation.

In examples, there is a device for converting ammonia (NH.sub.3) in a human breath sample to nitric oxide (NO). The device comprises a tube and a heater. The tube comprises an inlet, an outlet, and a wall defining an internal surface of the tube and an external surface of the tube. The wall comprises substantially the same material along a thickness from the internal surface of the tube to the external surface of the tube. The material is catalytic for conversion of ammonia to nitric oxide. The heater is configured to heat the wall.

A single-sided magnet and magnetic resonance imaging (“MRI”) system are portable and lightweight, enabling use as a point-of care (“POC”) MRI device. The portable MRI system includes a magnet assembly containing layers of magnet blocks, such as rare-earth magnet blocks. The magnet blocks are arranged in concentric rings in each layer, and surround a central aperture extending through the magnet assembly. The central aperture is sized to allow a medical instrument, such as a needle, to pass through the central aperture. The portable MRI system can therefore be used for image guidance in lumbar puncture (“LP”) and other medical procedures.
