Manual ventliation or resuscitation device

Abstract

A manual ventilation or resuscitation device is provided. The body of the device has rigid panels that encompass a sealed volume and are movable with respect to each other. The body has a displacement in a direction of a hand displacement and at least one other direction. A size adjuster adjusts the body displacement(s) between the states. A frequency adjuster adjusts the time to restore the volume or to adjust the time to compress the volume. The body provides an ergonomic fit to a user's hand, which reduces fatigue. The volume and/or frequency adjustments provide a user with reliance on a more or less constant tidal volume and tidal rate. Such adjustments allow usage of the device on any patient, regardless of individual factors such as physical condition, body/lung size, age and sex. Multiple devices could easily be stacked or nested with each other, which reduces storage space.

1 . A ventilation or resuscitation device, comprising:
 a body with rigid panels encompassing a sealed volume with an inlet mechanism and an outlet mechanism, the rigid panels movable with respect to each other, wherein the body having an uncompressed state and a compressed state, wherein the body having at least a first displacement and a second displacement, and wherein the second displacement is a function of the first displacement and the geometry of the panels, wherein a second panel is adjacent to and extends from a first panel in a first direction, a third panel is adjacent to and extends from the first panel in a second direction, and a fourth panel is adjacent to and extends from the first panel in a third direction.   
   
   
       2 . The device of  claim 1 , further comprising a size adjuster to adjust one or more of the body displacement changes between the states. 
   
   
       3 . The device of  claim 2 , wherein the size adjuster adjusts the one or more of the body displacement changes up to 170 mm. 
   
   
       4 . The device of  claim 1 , further comprising a volume adjuster to adjust the volume changes between the states. 
   
   
       5 . The device of  claim 1 , further comprising a volume restoring mechanism to restore the volume from the compressed state to the uncompressed state. 
   
   
       6 . The device of  claim 1 , further comprising a frequency adjuster to adjust the time to restore the volume from the compressed state to the uncompressed state or to adjust the time to compress the volume from the uncompressed state to the compressed state. 
   
   
       7 . The device of  claim 1 , wherein any of the body displacements of each of the panels is up to 85 mm. 
   
   
       8 . The device of  claim 1 , wherein the change in the volume between the states ranges from 1 to 500 cc. 
   
   
       9 . The device of  claim 1 , wherein the one or more of the body displacements between the states comfortably fits between a thumb of a hand, one or more fingers of the hand and the web of the hand. 
   
   
       10 . The device of  claim 1 , wherein the one or more of the body displacements between the states is defined by the natural range of a grasping motion of a hand. 
   
   
       11 . The device of  claim 1 , further comprising a feedback mechanism configured to provide feedback on one or more of the frequency of compression of the device and the tidal volume delivered. 
   
   
       12 . The device of  claim 1 , further comprising a visual feedback mechanism. 
   
   
       13 . The device of  claim 12 , wherein the body comprises a transparent section configured such that the visual feedback mechanism is visible from outside of the body of the device. 
   
   
       14 . The device of  claim 1 , further comprising an audible feedback mechanism. 
   
   
       15 . The device of  claim 1 , further comprising stacking or nesting capabilities for stacking the devices. 
   
   
       16 . The device of  claim 1 , wherein the change in the volume between the uncompressed state and the compressed state ranges from 250 to 1200 cc. 
   
   
       17 . The device of  claim 1 , wherein the change in the volume between the uncompressed state and the compressed state ranges from 1 to 1400 cc. 
   
   
       18 . The device of  claim 1 , wherein the panels are operably connected by one or more movable structures. 
   
   
       19 . The device of  claim 1 , wherein the movable structures comprise hinges. 
   
   
       20 . The device of  claim 1 , wherein the first panel and the second panel rotate around a first axis, and wherein the third panel rotates around a second axis, wherein the second axis is substantially orthogonal to the first axis.
