  • Publication number: 20220354386
    Abstract: A shivering detection apparatus (100) for detecting shivering of a patient (150) is provided. The apparatus (100) comprises a control unit (110) operatively connected to a transmit unit (120), for transmitting a transmit signal (170) based on a reference signal (140) of a transmit frequency towards the patient (150). The control unit is further operatively connected to a receive unit (130), for receiving a receive signal (190) as a portion of a reflected signal (180) comprising a portion of the transmit signal (170) reflected by the patient (150). The control unit (110) is configured to compare the receive signal (190) to the reference signal (140) and to detect shivering of the patient (150) as differences between the receive signal (190) and the reference signal (140). An associated method and sensor head is also provided.

  • Patent number: 10561527
    Abstract: Devices for cerebral and systemic cooling via a patient's nasopharyngeal cavity are described. Cooling assemblies include at least one elongate tubular member having first and second lumens, a source of liquid coolant, a gas source communicating with the first lumen, and a switch for alternately connecting the liquid coolant source to the second lumen. The first lumen transports a compressed gas and the second lumen transports a volatile liquid. The pressurized fluid may be a perfluorocarbon. The perfluorocarbon may be perfluorohexane, perfluoropentane, or 2-methyl-perfluoropentane. The gas may be air, oxygen, or a combination.

  • Patent number: 10076441
    Abstract: A method for cerebral cooling is described using a cooling assembly, which includes first and second elongate tubular members adapted for insertion into a nasal cavity of a patient through the patient's nostrils. The elongate tubular members each have a proximal end, a distal end, a lumen extending therebetween, and a plurality of ports in fluid communication with the lumen. The cooling assembly also includes a manifold and a reservoir, which contains a pressurized fluid that includes a propellant having a boiling point less than 22° C. The elongate tubular members are inserted into the nasal cavity through the patient's nostrils and pressurized fluid is delivered onto a surface of the nasal cavity by infusing the pressurized fluid from the reservoir through the manifold, into the lumens and through the plurality of ports of the first and second elongate tubular members.

  • Patent number: 9775741
    Abstract: Methods for cerebral cooling are described. Cooling assemblies include elongate tubular members, a reservoir containing a pressurized fluid, and a manifold connecting the reservoir and elongate tubular members. After insertion of the elongate tubular members into the patient's nostrils, a pressurized fluid is delivered onto a surface of the patient's nasal cavity through a plurality of ports in the elongate tubular members. The delivery of the fluid causes cooling by direct heat transfer through the nasopharynx and hematogenous cooling through the carotids and the Circle of Willis.
