US 12,178,949 B2 · Pressure-mitigation apparatuses for improved treatment of immobilized patients and associated systems and methods

Abstract

Introduced here are pressure-mitigation apparatuses able to mitigate the pressure applied to a human body by the surface of an object. A controller device can be fluidically coupled to a pressure-mitigation device that includes a series of selectively inflatable chambers. When a pressure-mitigation device is placed between a human body and a surface, the controller device can continuously, intelligently, and autonomously circulate air through the chambers of the pressure-mitigation device. As further discussed below, the controller device may cause the chambers to be selectively inflated, deflated, or any combination thereof. Such an approach is useful in a variety of contexts. For example, pressure-mitigation apparatuses may be used to improve treatment of patients suffering from respiratory illnesses and patients who are partially or completely immobilized for extended durations (e.g., as part of a medical procedure).

Dependent claims

A system for alleviating pressure applied to a living body undergoing treatment with an extracorporeal membrane oxygenation (ECMO) machine includes at least two tubes through which blood is obtained from, and then returned to, the living body for oxygenation, the system comprising:

a pressure-mitigation device that includes chambers intertwined around an epicenter in a geometric pattern;
a pump configured to generate a flow of air for pressurizing the chambers of the pressure-mitigation device;
and
a controller that includes—
a communication module configured to establish a channel over which to wirelessly communicate with the ECMO machine, and
a processor configured to:
receive input that specifies locations at which the at least two tubes are connected to the living body,
identify a programmed pattern for inflating the chambers of the pressure-mitigation device based on the input, and
cause the chambers of the pressure-mitigation device to be inflated to varying degrees in accordance with the programmed pattern, so as to shift pressure that is applied to an anatomical region of the living body by an underlying surface when the living body is positioned on the pressure-mitigation device such that the anatomical region is proximate the epicenter.

A system for alleviating pressure applied to a living body undergoing treatment with a mechanical ventilator, the system comprising:

a pressure-mitigation device that includes chambers intertwined around an epicenter in a geometric pattern;
a pump configured to generate a flow of air for pressurizing the chambers of the pressure-mitigation device;
and
a controller that includes—
a communication module configured to establish a channel over which to wirelessly communicate with the mechanical ventilator, and
a processor configured to:
receive input that specifies a frequency at which the mechanical ventilator pushes air into the lungs of the living body,
identify a programmed pattern for inflating the chambers of the pressure-mitigation device based on the input, and
cause the chambers of the pressure-mitigation device to be inflated to varying degrees in accordance with the programmed pattern, so as to shift pressure that is applied to an anatomical region of the living body by an underlying surface when the living body is positioned on the pressure-mitigation device such that the anatomical region is proximate the epicenter.
