  • Patent number: 11266523
    Abstract: Methods and apparatus for an improved contrast therapy device that delivers alternating heated and chilled temperature fluids to a contrast thermal therapy pad. Mitigation processes maintain water temperature in hot water tanks and cold water tanks in order to keep water temperatures in the respective tanks from drifting beyond a desired setpoint range when the system switches a therapy state from a cooling cycle to a heating cycle or from heating cycle to a cooling cycle. Thermal shock is reduced to the fluid tanks. Mitigation techniques include delaying actuation of a return path flow, such as via a diverting solenoid. Mitigating delay can be a static time delay based upon one or both of: a volume of water in a therapy pad and related volume and rate of flow; and meeting a threshold transition temperature for return fluid temperature.

    Abstract: Embodiments described herein generally relate to devices and methods for stimulation or recording of accommodation of an eye. Accommodation of an eye naturally occurs through contraction of the ciliary muscle. Embodiments described herein can deliver electrostimulation to the ciliary muscle through a pair of electrodes which deliver power over an area of the sclera which is both positioned above and over an area which is substantially equivalent to the surface area of the ciliary muscle. In further embodiments, electrical impulses produced by the ciliary muscle can be received by one or more electrodes positioned proximate the ciliary muscle. Thus, by embodiments described herein, accommodation of the eye can be reproducibly achieved by external stimulation of the ciliary muscle or measured based on electrical impulses generated by or in conjunction with the ciliary muscle.

  • Patent number: 10123902
    Abstract: A patient temperature control system and method are provided for automated temperature control according to a programmed protocol. In one aspect, at least one programmed protocol may be established for each of a plurality of patient thermal therapy phases. In turn, the temperature of a thermal exchange medium may be controlled, based at least in part, upon the programmed protocol, during each of the phases. In another aspect, a plurality of programmed protocols may be established, wherein a selected one of the protocols (e.g. selected by a user at a user interface) may be utilized for automated temperature control during patient thermal therapy. The protocol(s) may include a target patient temperature and/or a set duration for one or more of the phase of thermal therapy. Further, the protocol(s) may be user-definable and modifiable during therapy.

  • Patent number: 10045880
    Abstract: The cooling system for patients with fever is a mechanical, fluid-based system for cooling patients suffering from fever. The cooling system for patients with fever includes a reservoir for containing a cooling fluid, which is maintained at a desired temperature. A temperature sensor is received in the reservoir. The temperature sensor is immersed in the cooling fluid for measuring the temperature thereof. A chiller is also received in the reservoir for selectively cooling the cooling fluid when the temperature thereof, measured by the temperature sensor, is above a pre-set temperature threshold. The reservoir communicates with a cooling pad, which is formed from a padded layer having at least one channel embedded therein. At least one pump and tubing is provided for circulating the cooling fluid through the reservoir and the cooling pad. In use, the cooling pad is applied to the skin of a patient with a fever.

  • Patent number: 9918502
    Abstract: A conditioning garment has an array of tubes (11) for passing heated/cooled fluid to heat/cool a wearer of the garment. The array of tubes (11) terminate at a connector (16) for connection to a source of heated/cooled liquid. The connector (16) comprises a male part (15) and a female part (17) with a releasable latch (22, 34, 40) acting between the male and female parts (15, 17) to hold the male part (15) in engagement with the female part (17). The releasable latch includes a release member (40) moveable in a rectilinear path away from the connector (16) to release the latch and allow separation of the male part (15) from the female part (17). The male and female parts (15, 17) are self-sealing on disengagement. This allows for automatic separation of the male and female parts (15, 17) in an emergency.

  • Patent number: 9744071
    Abstract: The present invention provides a method and device for non-invasive anatomical and systemic cooling, fluid removal and/or energy removal. The present invention provides for removal of fluid and cooling of various bodily fluid-containing spaces or surfaces, such as mucus-containing spaces or surfaces via delivery of a dry fluid not including a coolant into or upon the mucus-containing space or surface. Exposure of mucus to the dry fluid yields evaporation of body fluid, removal of energy, cooling of the anatomical feature, and systemic cooling. Therefore, therapeutic hypothermia may be achieved for neuroprotection of various organs after ischemic insult, like the brain after cardiac arrest. Similarly, excess fluid removal is achievable for treatment of cardiogenic shock or other conditions that cause significant fluid build-up, especially in cases of compromised renal function.
