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.

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&#xb0; 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.

Devices for cooling the nasal cavity

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.

Methods for cerebral and systemic cooling via a patient's nasopharyngeal cavity are described. In one method, a cooling assembly is inserted into a nasal cavity through a patient's nostril. A substantially dry gas is delivered through a lumen of the catheter onto the surface of the patient's nasal cavity. Evaporative heat loss cools the patient's nasal cavity. If additional cooling is needed, a liquid coolant is delivered through a separated lumen of the catheter. The liquid coolant is nebulized at a plurality of delivery ports on the distal end of the catheter and is delivered onto the surface of the patient's nasal cavity in combination with the dry gas. The dry gas enhances evaporation of the nebulized coolant and additional cooling is provided from the evaporative heat loss of the liquid coolant.

A method for providing and adjusting cerebral cooling in response to changes in a physiological parameter. A spray having a boiling point between 38-300&#xb0; C. is delivered to the surface of a patient's nasal cavities. The spray causes cooling by direct heat transfer through the nasopharynx and hematogenous cooling through the carotids and the Circle of Willis. A physiological parameter, such as cerebral temperature, changes in cerebral blood flow or brain oxygenation is monitored. The delivery rate of the spray is adjusted in response to the physiological parameter.

A cerebral cooling device that uses a pressurized source to deliver a fluid that evaporates in the nasal cavity to provide cooling and has a balloon on the distal end that inflates from some of the pressure front the pressurized source. The device includes a nasal catheter having delivery ports located in the distal region and a balloon on the distal end. The proximal end of the catheter is in fluid communication with a pressurized source of a low boiling point fluid. A manifold located between the pressurized source and the catheter distributes the fluid and pressure from the pressurized source to a first lumen of the catheter to inflate the balloon and to a second lumen of the catheter through the delivery ports to cool the nasal cavity. A check valve in the manifold ensures that the fluid and pressure are first delivered to the balloon.

A method for cerebral and systemic cooling by providing a nebulized liquid having a boiling point of 38-300&#xb0; C. The nebulized liquid is delivered as a mist or a spray via the nasal and/or oral cavities of a patient. The mist causes cooling by direct heat transfer through the nasopharynx and hematogenous cooling through the carotids and the Circle of Willis. Compositions and medical devices for cerebral and systemic cooling are also provided. Cooling assemblies, and methods of use, are also provided that include flexible balloon assemblies that are inserted to various locations in a patient's body. The flexible balloons are then infused with a liquid having a temperature between about &#x2212;20&#xb0; C. and about 37&#xb0; C. The flexible balloon assemblies can be inserted into the nasal cavity, oral cavity, throat, stomach, and other locations to effect cerebral cooling.

A method for cerebral and systemic cooling by circulating a cold liquid through a nasal catheter looped through the patient's nasal cavities and around the nasal septum. The nasal catheter is inserted into the patient's first nostril, advanced through the nasal cavity, around the nasal septum and out of the patient's second nostril. A cold fluid having a temperature between about &#x2212;20&#xb0; C. and about 37&#xb0; C. is flowed though a lumen in the nasal catheter to cool the nasal cavity. The nasal catheter may have one or more flexible balloons mounted on the catheter such that when the catheter is looped around the nasal septum, the balloon(s) are positioned in a portion of the patient's first and second nasal cavities. When a cold liquid is circulated through the catheter lumen, the flexible balloons expand to a contact the inner walls of the nasal cavities and provide direct cooling of the nasal cavities.

A liquid dispensing device. The liquid dispensing device has a tray for holding a liquid at a relatively constant level. A syringe is used for drawing fluid from the tray. A liquid container containing a liquid is positioned upside-down in the tray. Atmospheric pressure on the liquid in the tray and a vacuum inside the liquid container prevents liquid from draining from the container except when the liquid level in the tray drops to a level sufficient to allow air into the liquid container and to allow fluid to flow from the liquid container into the tray. The fluid flows from the liquid container into the tray until the level of liquid in the tray returns to the relatively constant level. The positioning of the syringe for drawing fluid is simplified in that the level of fluid in the tray is maintained at an approximately constant level despite withdrawal of quantities of fluid from the tray.

Liquid dispensing device

A liquid dispensing device. The liquid dispensing device has a tray for holding a liquid at a relatively constant level. A syringe is used for drawing fluid from the tray. A liquid container containing a liquid is positioned upside-down in the tray such that the opening of the liquid container defines a vertical position that is slightly below the liquid level in the tray. Atmospheric pressure on the liquid in the tray and a vacuum inside the liquid container prevents liquid from draining from the container until the fluid level in the tray drops to a level approximately equal to the vertical position of the opening. The positioning of the syringe for drawing fluid is simplified by reason of the fact that the level of fluid in the tray is maintained at an approximately constant level despite withdrawal of quantities of fluid from the tray.

A buckle safety device formed for use with a seat belt assembly. The seat belt assembly includes a tongue and a buckle. The buckle safety device includes a housing having a cutout and a buckle receiving opening. The cutout and the buckle receiving opening communicate with a cavity inside the housing. The cutout is configured for receiving an elongated object for releasing the tongue from the buckle when the tongue is mated therewith. A base receiving member extends from the housing. The base receiving member is arranged proximate the buckle receiving opening and has a base receiving slot extending therethrough.
