A percussive pulsing therapy device configured for delivering pulsating or intermittent airflow to a patient device, such as a patient vest. The percussive pulsed air device may have an airflow generator for controlling amplitude of the percussive pulsed air and a pulse frequency control module for controlling frequency of the percussive pulsed air. In some embodiments, the pulse frequency control module may have a rotatable fan blade, such as a circular fan blade having one or more cutout portions. In some embodiments, the rotating fan blade may have one or more channels configured to redirect percussive pulsed air. Moreover, a percussive pulsed air device of the present disclosure may have a dampening element flowably coupled to an inlet of the pulse frequency control module. In some embodiments, at least one inlets of the pulse frequency control module may be arranged on a different airflow plane than one or more outlets.

An apparatus for reanimation of a patient that includes a plunger driven by a drive to perform a compressive massage on the patient's body, a position measuring device that measures the respective position of the plunger during its compressive massaging motion, and a holding device for the drive and the plunger.

A wearable thorax percussion device for dislodging mucous buildup in the airways of a human patient, the device comprising a garment fitting over the thorax, a rigid element attached to the external surface of the garment, an electromechanical actuator retained by the rigid element to intermittently percuss the thorax, and an electronic controller for generating and modulating an electrical signal to energize the actuator. The rigid element may be adjustably positioned on the garment to accommodate thoraxes of different dimensions. The actuator may be compressible between the rigid element and the thorax to better maintain contact with the thorax.

A device for the determination of at least one compression parameter during the administration of cardiopulmonary resuscitation (CPR) on a patient. The device includes a compression unit adapted to move in accordance with the chest of a patient and a surface unit adapted to move in accordance with a surface supporting the patient. The compression unit has one of a signal component and reference component, the surface unit has the other of the signal component and the reference component. The device also includes a processor configured to determine a relative measurement between the compression unit and the surface unit using data derived from the signal component and the reference component. The processor is further configured to determine the at least one compression parameter based on the relative measurement. The determined at least one compression parameter takes into account any motion and/or displacement of the surface.

The present invention relates generally to a support structure for fixating a patient to a treatment unit, and especially to a support structure for fixating the patient to a cardiopulmonary resuscitation unit. An embodiment of the support structure comprises a back plate for positioning behind said patient's back posterior to said patient's heart and a front part for positioning around said patient's chest anterior to said patient's heart. Further, the front part can comprise two legs, each leg having a first end pivotably connected to at least one hinge and a second end removably attachable to said back plate. Said front part can further be devised for comprising a compression/decompression unit arranged to automatically compress or decompress said patient's chest when said front part is attached to said back plate.

Systems and methods of monitoring medical therapies performed by wearable devices using electrical probes. In one example, a pulmonary physiotherapy device implements a treatment protocol function gated and modulated using electrical impedance sensors and metrics. The sensors operate to measure electrical impedance of bodily tissue. An electronic controller controls operation of the wearable device. The medical therapy can be modified based on the impedance measurements to maximize efficacy.

An elevation device used in the performance of cardiopulmonary resuscitation (CPR) and after resuscitation includes a base and an upper support operably coupled to the base. The upper support is configured to elevate an individual's upper back, shoulders and head. The elevation device also includes a chest compression device coupled with the base. The chest compression device is configured to compress the chest and to actively decompress the chest.

A CPR chest compression system includes a retention structure that retains the body of a patient, and a motor and a compressor that can perform CPR compressions to the chest of the patient. The motor is powered by a battery that is located on the retention structure but away from the motor, and is electrically connected to the motor via one or more wires. Accordingly the weight and volume of the battery can be located away from a top portion of the retention structure. This renders the CPR system is less heavy at the top, and therefore less likely to tilt and start compressing the chest at a different point. Moreover, this permits X-Rays of a larger footprint to go through the CPR system and reach the patient, in embodiments where the components are transparent to X-Rays.

A multi-functional airbag comprises a main body, a front side of the main body is provided with an opening, a rear side of the main body opposite to the opening is provided with a functional cavity to install a functional assembly, a left air chamber and a right air chamber communicated with each other are symmetrically configured at two sides of the main body, and the functional assembly is installed in the functional cavity. While in use, the air chambers are inflated, as a result the main body is inflated to enable to clamp two sides of the human neck; while not in use, the air chambers are deflated to reduce the volume to make it portable. Meanwhile, massage functioning members are configured to massage the acupuncture points by vibration therapy, pulse therapy, heat therapy, infrared light therapy, and/or magnet therapy, and the therapy effect is obvious.

Techniques and devices for extending a piston, for example connected to a medical device such as a mechanical CPR device, to accommodate different sized patients, are described herein. In some cases, a piston of a mechanical CPR device may include an inner piston at least partially slidable into an external piston sleeve. In one aspect, an external piston spacer may be attached to an outward surface of the inner piston to extend the length of the piston. In another aspect an internal bayonet sleeve may contact one or more locking rods at various positions, enabling adjustment of the length of the inner piston. In yet another aspect, a piston adapter may be removably attached to the end of the piston. In all aspects, the change in length of the piston may be detected and used to modify movement of the piston, for example to more safely perform mechanical CPR.
