Abstract
A compression device may include a compression plunger in operable communication with a fulcrum assembly and housing assembly in operable communication with a stepper assembly. The compression device may be constructed and arranged to allow a user to administer CPR to a patient by stepping on a portion of the stepper assembly to generate hydraulic power that may be utilized to move the compressor plunger to apply compressive force to the patient's chest. The compression device may include a housing assembly and fulcrum assembly constructed and arranged to provide for variable height and width such that patients of varying sizes can be accommodated and may receive CPR.
Claims19
A compression device, comprising:
- a compression plunger;
- a stepper assembly;
- a housing assembly comprising:
- a second compressor drive lever hydraulic motor in operable communication with a first compressor drive lever hydraulic motor via at least one hydraulic hose;
- a first height adjustment foot in operable communication with the housing assembly;
- a second height adjustment foot in operable communication with the housing assembly;
- a housing defining at least one slot constructed and arranged to slidably engage with a fulcrum assembly, the fulcrum assembly comprising a fulcrum frame, a compression drive lever hingedly attached to the compression plunger, and a compression counter, wherein the compressor plunger is hingedly attached to an end joint of the compression drive lever opposite a distal end of the compression drive lever and the compression drive lever defines a variable compression force recess near the distal end that varies in depth such that compression force applied by the compression plunger head to a patient is variable and adjustable by sliding the fulcrum assembly within the at least one slot.
A compression device, comprising:
- a compression plunger comprising a plunger head, a plunger neck, a tapered neck portion, and a safety stop collar;
- a stepper assembly comprising a first compressor drive lever hydraulic motor, a handlebar, at least one stepper pedal, a gear assembly in operable communication with the first compressor drive lever hydraulic motor and the at least one stepper pedal;
- a housing assembly comprising:
- a second compressor drive lever hydraulic motor in operable communication with the first compressor drive lever hydraulic motor via at least one hydraulic hose;
- a first height adjustment foot in operable communication with the housing assembly and comprising a hydraulic drive motor height offset mechanism;
- a second height adjustment foot in operable communication with the housing assembly;
- a compressor recoil generator;
- a width slider assembly;
- a plunger stability collar;
- a housing constructed and arranged to house the compressor recoil generator, the width slider assembly, and the plunger stability collar, the housing defining at least one slot constructed and arranged to slidably engage with a fulcrum assembly;
- and
- a fulcrum assembly comprising a fulcrum frame, a compression drive lever hingedly attached to the compression plunger, and a compression counter, wherein the compressor plunger is hingedly attached to an end joint of the compression drive lever opposite a distal end of the compression drive lever and the compression drive lever defines a variable compression force recess near the distal end that varies in depth such that compression force applied by the compression plunger head to a patient is variable and adjustable by sliding the fulcrum assembly within the at least one slot.
