A system for assisting with a chest compression treatment being administered to a patient. In one aspect, the system for assisting with chest compression treatment includes at least one sensor configured to measure blood flow data, one or more processors, in communication with the at least one sensor, and an output device configured to provide the output indication to the rescuer. The one or more processors are configured to perform operations including receiving the blood flow data from the at least one sensor, based on the blood flow data, generating arterial blood flow data and venous blood flow data, providing an estimation of chest compression effectiveness based on the arterial blood flow data and the venous blood flow data, the estimation being based on at least one peak comparison of arterial blood flow and venous blood flow, and generating an output indication of the estimation of chest compression effectiveness.

Acupuncture needles may be used for piercing tissue with less trauma than may occur when employing larger gauge needles. However, because acupuncture needles are fabricated and packaged differently than are larger gauge needles, acupuncture needles may be less compatible with certain manufacturing processes. Needle assemblies compatible with manufacturing processes may comprise a continuous support material having a plurality of apertures defined therein, and a first injection molded coupler that surrounds a proximal portion of an acupuncture needle and connects the acupuncture needle to a first location upon the continuous support material, such that the acupuncture needle is held in a pre-determined orientation with respect to a longitudinal axis of the first injection molded coupler. The acupuncture needles in adjacent apertures may also be spaced apart substantially uniformly.

An example method includes administering a treatment to a subject during a time interval. The example method further includes receiving, from an external device, a first signal indicating a physiological parameter of the subject detected during the time interval; removing, from the physiological parameter, an artifact associated with the treatment; and in response to removing the artifact from the physiological parameter, outputting a second signal indicating the physiological parameter.

A multimodal haptic device operating as a closed-loop system, the device including a pipeline configured to allow a closed-loop flow of a fluid medium, a manifold operatively connected to the pipeline, the manifold having a pump and a valve to control and regulate a flow of the fluid medium along the pipeline, and a display unit operatively connected to the pipeline, the display unit having a tactile display and a valve operatively connected to the tactile display for regulating an efflux of the fluid medium from the tactile display into the pipeline.

Systems and methods for non-invasive management of head pain are disclosed. The system includes a headgear configured to be worn on a patient's head. The headgear can include a base and an extension coupled to the base, and a number of therapy devices removably or adjustably attached to the base or the extension. The therapy devices can deliver various modes of therapeutic energy at respective target sites on the head, including neuromodulation of peripheral pain pathways and/or the cerebral cortex, and therapy modalities to facilitate or enhance the neuromodulation effects. The system can include a portable device that enables the user to control the therapy devices on the headgear. The user can use the portable device to optionally access a web-based repository to acquire information about headgear usage from other users, and use that information to guide the programming of the therapy devices.

A CPR system includes a retention structure to retain the patient's body, and a compression mechanism to perform CPR compressions to the patient's chest. The CPR system further includes a processor to control the compression mechanism, and thus the performance of the CPR compressions. In embodiments, the CPR system compresses at a rate or frequency that is varied based on feedback gathered from physiological sensors that detect physiological characteristics of the patient during treatment.

The present disclosure includes various examples for cooling electronics within a medical device while preventing or reducing the risk of an interior of the medical device being contaminated with a pathogen. The present disclosure includes a medical device having an air deflector to deflect potentially contaminated air from infecting a patient or caregiver. The present disclosure also includes medical devices with disinfectant devices installed to disinfect air either before entering the medical device or before exiting the device. Other examples of the present disclosure include medical devices that are sealed from outside air and fluids, and which may include a cooling device on an exterior surface which may be cleaned and/or removed after each use.
