Described is a wearable device configured to oscillate a chest of a user. The wearable device may include a chest wall oscillator, a sound detector, and a controller for controlling operations of the chest wall oscillator, based on sound from the sound detector. The chest wall oscillator may be mounted on the chest of the user to oscillate the chest of the user. The sound detector may detect the sound from the chest of the user before, during, and/or after operation of the chest wall oscillator. The controller may change one or more of a frequency, intensity, or duration of the oscillations of the chest wall oscillator, depending on an analysis of the sound from the sound detector.

Embodiments of a Cardio-Pulmonary Resuscitation (“CPR”) device are disclosed. A CPR device can include a compression mechanism configured to perform successive CPR compressions on a chest of a patient, the compression mechanism including a support portion configured to be placed underneath a patient, a piston, and a contact surface configured to make contact with the chest at a first orientation with respect to the support portion; and a controller communicatively coupled with the compression mechanism. The controller can be configured to receive at least one input and determine whether the first orientation of the contact surface should be adjusted based on the at least one input. The controller can further, responsive to a determination that the first orientation of the contact surface should be adjusted, cause the contact surface to move so that the contact surface makes contact with the chest at a second orientation with respect to the support portion.

A rigid back member of an automatic mechanical chest compression device is secured to a torso support platform. The torso support platform includes a main support strap immediately below where the rigid back member is secured to the torso support platform, and an upper support strap above where the rigid back member is secured to the torso support platform. The torso support platform tapers towards the top at approximately where a patient's shoulders are located when properly secured to the torso support platform. Additional straps may also be utilized, for example, shoulder straps extend over the shoulders of the patient and are secured to the torso support platform at a point below the patient's armpits, or straps that extend from the tapered section and secure to the automatic mechanical chest compression device.

A CPR training manikin The training manikin can have a lighted rate monitor assembly. The lighted rate monitor can include a body portion, the body portion including an electronic control board. A chest compression assembly can be joined to the body portion, the chest compression assembly comprising input sensors electrically connected to the electronic control board. The lighted rate monitor assembly can have an electrical cord assembly having a plug member at a proximal end for removable electrical connection with the electronic control board, and having at a distal end, a light.

A valve assembly attached to a capacitor such that pressurizing the capacitor to a first positive pressure threshold induces the valve assembly to open, the pressurized air is released to the patient, and then as the pressure in the capacitor drops to a second pressure threshold the valve closes and the capacitor begins to build pressure until the first positive pressure threshold is achieved and the process repeats. Relative to the valve assembly and integrated therein, is an incrementally adjustable index knob to vary the rate of a biasing force performing work against the actionable valve face of the diaphragm functional surface to set the performance of the valve assembly, thereby increasing the potential for correct operation across a range of oscillating rates supporting a broad spectrum of patient therapies and types.

An ambulatory respiratory assist device utilizes a cuirass worn on the chest and/or abdomen and supported by a hip belt so that it does not place a load on the patient's shoulders. The belt also supports a ventilator that includes a pump and its power supply, valving, controls and auxiliary equipment. The device is optionally integrated with auxiliary features such as chest wall vibration, which can be achieved by utilizing cuirass pressure modulation, with shoulder or upper arm supports for simulating the “tripod position”, with positive pressure ventilation apparatus, or with patient monitoring. Shoulder or upper arm supports can extend directly from the belt to the shoulders or upper arms, utilized independently of the cuirass, and optionally integrated with one or more of the above-mentioned auxiliary features.

A medical device uses UWB units to infer a position of an adjunct positioned in proximity to an exterior portion of a patient's body. The position information can be used to provide CPR feedback to a rescuer. In other applications, the position information can be used to provide prompts to a user to change the position of the adjunct.

Compression garments and methods may include a head garment configured to be positioned around both sides of a head of a body from a posterior of the head to an anterior of the head and a torso garment. Such garment portions may include one or more controllable pressure applying regions to move lymph from the head downward to the torso.

Medical radar devices, including ultra-wideband (UWB) devices, for use in assisting and/or guiding cardiopulmonary resuscitation (CPR) by indicating one or more of: compression depth, compression frequency, and a return to spontaneous circulation. The devices and methods described herein may use reflected energy applied to a patient's chest to determine cardiac motion and/or chest compression and provide feedback to the person applying the CPR. In some variations the device is incorporated as a part of another resuscitation device, such as a defibrillator or automatic compression device.

Shockwaves or modulated pressure waves are applied to targeted lung tissue of humans or animals, including lung tissue having a viral or bacterial infection or a chronic lung condition, to destroy or render innocuous different pathogens and treat the underlying chronic or acute medical conditions.
