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.

Description

[0001]This application claims priority under 35 U.S.C. § 120 as a continuation of U.S. patent application Ser. No. 11 / 147,070 filed Jun. 6, 2005, currently pending, and the disclosure of which is incorporated by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates generally to manual ventilation or resuscitation devices. More particularly, the invention relates to manual ventilation or resuscitation devices with control over the amount and rate of e.g. air, oxygen or oxygen-enriched air delivered to an individual and with a design that easily fits a user's hand.BACKGROUND OF THE INVENTION[0003]Manual ventilation or resuscitation is performed on an individual when they are unable to breathe independently. Typically, this occurs when an individual is transported from one section of a hospital to another section such as an emergency room and an intensive care unit. Manual resuscitation also occurs during cardiopulmonary resuscitation (CPR), which is a sta...

Benefits of technology

[0014]One advantage of the device is the ergonomic fit of the body to a user's hand in both uncompressed and compressed state, which reduces fatigue to hand and / or arm muscles. Another advantage of the device is the ability to adjust the volume and / or frequency so that the user can rely on a more or less constant tidal volume and tidal rate. Such ability allows one to use the device on any patient, regardless of individual factors such as physical condition, body / lung size, age and sex. Yet another advantage is that multiple devices could easily be stacked or nested with each other. In exemplary embodiments, the design and geometry could be configured to include such stacking or nesting capabilities.

Problems solved by technology

Unfortunately, current manual ventilation or resuscitation devices are not suitable for the desired monitoring and control of tidal volume delivery.
