Embodiment Construction

[0053] This article describes an indirectly cooled, single-occupancy cryotherapeutic unit, or cryotherapeutic chamber, in which cool air is recirculated through the chamber and recooled by a cryogen heat exchanger to provide a more uniform temperature distribution within the chamber from top to bottom. In addition, the cold air flow is controlled so that the amount of cooling (cold intensity) can be adjusted to suit specific patient requirements, including but not limited to the patient's individual physical characteristics, and the integrated controller can apply a customized treatment regimen. For example, treatment regimens can be tailored according to the type of condition being treated (e.g., fatigue, sleep, recovery, injury), and can be modified according to patient characteristics (e.g., gender, size, height, weight, skin type). The cold treatment provided may also be adjusted by controlling the air flow rate through the chamber at one or more locations to alter the effe...

Abstract

A cryotherapy apparatus includes a heat exchanger, a cryotherapy chamber, cryogenic nitrogen supply and exhaust conduits to and from the heat exchanger, an air return conduit to flow warmed air from the cryotherapy chamber to the heat exchanger, an air supply conduit to flow chilled air from the heat exchanger to the cryotherapy chamber, a variable speed fan to cause flow of air through a loop including the air supply and return conduits, the heat exchanger, and the cryotherapy chamber, and a controller programmed to control the flow rate of air by regulating the speed of the variable speed fan according to a treatment protocol; the invention further provides a method of delivering cryotherapy according to a customized treatment protocol taking into account one or more of: a patient's treatment goals, a customization factor, a personalization factor, and an adaptation factor.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application No. 62 / 317,953, filed April 4, 2016, and U.S. Provisional Application No. 62 / 453,670, filed February 2, 2017, the entire contents of which are incorporated herein by reference. Background technique [0003] This article describes an apparatus and method for delivering customized cryotherapy treatments using an indirectly cooled single-person cryotherapy unit or a multi-person cryotherapy chamber. [0004] Whole body cryostimulation / cryotherapy (WBC) is a non-invasive technique characterized by relatively short bursts of cold (-90°C to -140°C) lasting approximately 2-4 minutes to the periphery of the body (i.e. exposed skin surface area) triggers and utilizes the response to cold, eliciting various physiological responses that promote healing and recovery. [0005] Existing one-person cryotherapy devices, or frozen tissue, include a chamber in which the pat...
