A pressurizing device includes a main body and a pressurizing mechanism having a controlling assembly and a pressing assembly arranged on the controlling assembly and movable relative to the main body. The controlling assembly has a base body arranged on the main body and a controlling member having a pivot portion and a driving portion, the pivot portion is pivoted to the base body so that the controlling member is swingable between pressurizing and releasing positions, and the pressing assembly has a controlled portion comovable with the driving portion and a pressurizing portion for pressing an object. When the controlling member swings toward the pressurizing position, the driving portion drives the controlled portion to make the pressurizing portion press the object; when the controlling member swings toward the releasing position, the driving portion drives the controlled portion to depressurize the object.

A device for compressing the chest of a cardiac arrest victim.

A CPR chest compression device with a cooling exhaust flow path configured to direct cooling air flow through the device. A CPR chest compression device with a battery retainer interoperable with the control system to provide for controlled shut-down when an operator attempts to remove the battery during operation.

Devices that can provide a compressive force and a vibratory force to treat an area are described. In some configurations, the devices can include a substrate that can provide the compressive force and multiple independently controllable actuators that can provide the vibratory force to treat swelling, lymphedema or other conditions.

In some embodiments, a method may include monitoring use of a medical device. The method may include positioning a wearable harness of a medical device on a subject. The method may include selectively positioning at least some of a plurality of engines on and/or adjacent to at least one treatment area. The method may include applying an oscillation force to at least one of the treatment areas using at least some of the engines. The method may include mobilizing at least some secretions in an airway within the subject substantially adjacent to the treatment areas. The method may include monitoring use of the medical device by the subject using a controller associated with the medical device to determine if the medical device has been used effectively as prescribed.

An automated chest compression device for performing CPR, with distance sensors disposed on a compressing mechanism and on a structure fixed relative to the CPR patient, for determining inferior/superior movement of the compressing mechanism over the course of multiple compressions.

In some embodiments, a method may include clearing a biological airway. The method may include positioning an inner wearable harness on a torso of a subject. The method may include selectively positioning at least some of a plurality of engines on and/or adjacent at least one treatment area. At least one of the plurality of engines may be releasably couplable to the inner wearable harness. The method may include positioning an outer wearable harness on a torso of a subject. The method may include applying an oscillation force to at least one of the treatment areas using at least some of the plurality of engines. The method may include adjusting the applied oscillation force to the treatment area by activating the outer wearable harness. The method may include mobilizing at least some secretions in an airway within the subject substantially adjacent the at least one treatment area.

In some embodiments, a system may include an inner wearable harness worn, during use, on a torso of a subject. The system may include a plurality of engines which when activated apply an oscillation force. The system may include a positioning system which allows positioning at least one of the plurality of engines on the inner wearable system such that the oscillation force is applied to at least one treatment area of the subject. The oscillation force may mobilize, during use, at least some secretions in an airway within the subject substantially adjacent the treatment area. The system may include an outer harness worn, during use, on a torso of a subject. The outer wearable harness, when activated, adjusts the oscillation force applied by at least some of the activated plurality of engines to the treatment area.

In some embodiments, a kit may include systems allowing for clearing a biological airway. The kit may include an inner wearable system worn, during use, on a torso of a subject. The kit may include a plurality of engines which when activated apply an oscillation force to at least one treatment area of the subject. At least one of the plurality of engines may be releasably couplable to the inner wearable system. The oscillation force may be applied to at least one of the treatment areas of the subject such that the oscillation force mobilizes, during use, at least some secretions in an airway within the subject at least adjacent the treatment area. The kit may include an outer wearable system worn, during use, on a torso of a subject which when activated, adjusts the oscillation force. The kit may include one or more batteries and/or a control unit.

A mechanical chest compression device is secured to a gurney, transport stretcher or ambulance cot while engaging a patient's thorax to provide mechanical CPR during transport. The mechanical chest compression device compresses the patient's thorax against the gurney deck. The mechanical chest compression device may engage the side rails on the gurney, the gurney deck or any suitable structural elements of the gurney.
