Manual resuscitator regulating system

Abstract

A manual resuscitator regulating system for regulating the rate and volume of ventilation during manual resuscitation. The manual resuscitator regulating system may include an intake assembly configured to permit a selected volume of gas to flow into a chamber over a predetermined amount of time and/or an outtake assembly configured to permit a selected volume of gas flow out of the chamber over a predetermined amount of time. The intake assembly and/or the outtake assembly may include one or more adjustment mechanisms configured to allow a user to selectively adjust volume. The intake assembly and the outtake assembly may be configured to coordinate with one another to deliver a selected tidal volume and/or volume of gas. The manual resuscitator regulating system may include a placement indicator configured to indicate or guide a user where to squeeze or compress the chamber.

         24 . A manual resuscitator comprising:
 a compressible chamber having a flexible wall, the flexible wall of the chamber having a grip placement indicator configured to guide a user where to grip the chamber by hand, the grip placement indicator being configured to deliver a pre-set repeatable volume of air to a patient by manually compressing the grip placement indicator to a point where opposing portions of the flexible wall come into contact,   an intake assembly attached to the chamber and configured to permit air flow into the chamber at a pre-set in-flow rate; and   an outtake assembly attached to the chamber and configured to deliver the pre-set repeatable volume of air to a patient when a user manually grips the grip placement indicator and compresses the compressible chamber to the point where opposing portions of the flexible wall come into contact, the contact generating a finger sensed release signal, and   wherein the intake assembly and the compressible chamber are configured to generate a finger-sensed compression signal when the compressible chamber has completely refilled, indicating to the user that it is time to compress the compressible chamber again, wherein the pre-set volume of air delivered through use of the grip placement indicator, and a pace of repeatable compressions achieved through use of a series of alternating finger-sensed compression signals and finger sensed release signals results in a desired volume of air delivery to a patient in eight to twelve compressions per minute without any electronics or visual sensing by the user.   
     
     
         25 . The manual resuscitator of  claim 24 , wherein the intake assembly includes a first override aperture that permits air to flow into the compressible chamber at a rate faster than the pre-set in-flow rate. 
     
     
         26 . The manual resuscitator regulating system of  claim 25 , wherein the intake assembly allows the compressible chamber to refill in more than three seconds, the override aperture allowing the compressible chamber to refill in less than three seconds. 
     
     
         27 . The manual resuscitator regulating system of  claim 25 , wherein the outtake assembly includes a second override aperture selectable to disable the outtake assembly and permit a maximum amount of gas flow out of the compressible chamber. 
     
     
         28 . The manual resuscitator regulating system of  claim 27 , wherein the override aperture in the intake assembly has a different size and shape relative to the override aperture in the intake assembly. 
     
     
         29 . The manual resuscitator regulating system of  claim 24 , wherein the intake assembly has a first valve housing including a first regulator disc including the first override aperture, and a first control disc. 
     
     
         30 . The manual resuscitator regulating system of  claim 29 , wherein rotation of the first control disc with respect to the first regulator disc is controlled by a click stop mechanism. 
     
     
         31 . A manual resuscitator regulating system comprising:
 a compressible chamber having a flexible wall, the flexible wall of the chamber having a first grip placement indicator and a second grip placement indicator configured to guide a user where to grip the chamber,   an intake assembly attached to the chamber and configured to permit air flow into the chamber at a pre-set in-flow rate; and   an outtake assembly attached to the chamber and configured to permit a pre-set volume of air to flow out of the chamber when the chamber is properly gripped on the first and second grip placement indicators, and manually compressed to a deflated state where portions of the flexible wall associated with the first and second grip placement indicators are in contact, wherein the pre-set in-flow rate of the intake assembly allows intake of the pre-set volume over a time period equal to a time period between recurrent manual compressions of the chamber to the deflated state, and a finger sensed signal at a fully inflated state of the chamber where the outward expansion pressure of the compressible chamber exerted on the user's fingers sensed through the first and second grip placement indicators has stopped, prompting the user to recompress the chamber to the deflated state without any auxiliary timing device.   
     
     
         32 . The manual resuscitator regulating system of  claim 31 , wherein the intake assembly and the outtake assembly are be configured to deliver a selected tidal volume at a selected pressure. 
     
     
         33 . The manual resuscitator regulating system of  claim 31 , wherein the placement indicator is configured to allow a user to selectively adjust the user's grip circumferentially in a plane perpendicular to a longitudinal axis of the chamber. 
     
     
         34 . The manual resuscitator regulating system of  claim 31 , wherein the placement indicator may be configured to allow a user to selectively adjust the user's grip longitudinally along a longitudinal axis of the chamber. 
     
     
         35 . The manual resuscitator regulating system of  claim 31 , wherein the intake assembly is configured to permit the pre-set volume of air into the chamber over a five-seconds time period.

         37 . A method of manually resuscitating a patient, comprising:
 applying a respiratory device to a patient's airway, the respiratory device being connected to a chamber having a flexible wall, the flexible wall of the chamber having a first grip placement indicator and a second grip placement indicator configured to guide a user where to grip the chamber by hand,   selecting one of at least two different pre-set air in-flow rates, determining how long it will take for the chamber to completely refill with air after compressing the chamber by hand to a point where portions of the flexible wall associated with the first and second grip placement indicators are in contact, the contact generating a finger sensed release signal,   delivering a pre-set volume of air to the patient by manually compressing the chamber until portions of the flexible wall associated with the first and second grip placement indicators are in contact, generating the finger sensed release signal,   releasing compression of the chamber upon sensing of the finger sensed release signal, and allowing air intake into the chamber until the chamber is completely refilled with air, generating a finger-sensed compression signal, and   alternately repeating the delivering and releasing steps,   
       wherein the pre-set volume of air delivered through use of the grip placement indicator, and a pace of repeatable compressions achieved through use of a series of alternating finger-sensed compression signals and finger sensed release signals results in a desired volume of controlled air delivery of air to a patient in eight to twelve compressions per minute without any electronics, auxiliary timing devices, or visual sensing by the user 
     
     
         38 . The method of  claim 37 , further comprising, adjusting a setting on the intake assembly to be on a same setting as the outtake assembly.
