METHOD AND APPARATUS FOR IMMOBILIZING SUBJECTS UNDERGOING MECHANICAL CPR

摘要

The apparatus for immobilizing and treating a subject includes a suitable apparatus for performing mechanical CPR secured to an immobilization casing. The airtight flexible casing is secured to the apparatus for performing CPR, the casing having variable rigidity which varies as a function of the amount of air within the casing. Two or more slots through the casing permit passage of one or more elements of the CPR apparatus to pass through the casing. One or more incompressible windows may be included in the casing to optimize the performance of mechanical CPR by permitting one or more elements of the subject's skeleton to contact the CPR apparatus. A device for evacuating the air from within the flexible casing to control the rigidity of the casing is included within the CPR apparatus.

主权项

1. An apparatus for immobilizing and treating a subject comprising:
a piston compression system for repetitively compressing the chest of a subject with a chest compression unit driving a piston, the chest compression unit is supported by at least two legs secured to a backboard with the piston apposing the subject's chest; an airtight flexible casing secured to the backboard, the casing containing air and having two or more slots to permit passage of the at least two legs of the compression system through the casing wherein the casing has a variable rigidity which varies as a function of the amount of air within the casing; a vacuum pump for evacuating the air from within the flexible casing to control the rigidity of the casing; a plurality of beads located within the casing, the plurality of beads adapted to move and conform the casing to support the subject when the casing contains air, the plurality of beads adapted to be rigidly fixed in position when the casing is in a fully evacuated state.
