Apparatus and methods for providing extracorporeal blood circulation and oxygenation control include multi-stage de-airing of blood to provide automated cardiopulmonary replacement to preserve the viability or one or more organs in a clinically dead organ donor or harvested donor organ for subsequent transplantation to an organ receiver patient.

The present invention, in some embodiments thereof, relates to a method and scalable devices for hyperfast cooling and re-warming of samples. More specifically, it relates to cryogenic preservation of biological samples via vitrification. It includes: a liquid sample placed at ambient temperature in a flat thermo conductive container that in some embodiments additionally contains a detachable disposable or sterilizable thermo conductive spiral; transferring the sample to a cooling chamber using a linear percussion stepping motor drive; hyperfast cooling of the sample using streams of pressurized liquid coolant; transferring the sample to a detachable shipping/storage chamber filled with liquid coolant, from which the sample can be transferred to another vessel that contains liquid cryogenic coolant and moved back to the shipping/storage chamber. This chamber can be then attached to a re-warming chamber, in which the sample is heated to a biologically tolerant temperature above 0 degrees Celsius in a hyperfast manner.

A method for filling and venting a device for extracorporeal blood treatment is disclosed, such as a patient module in a heart-lung machine, without attached patient. A filling liquid from a filling liquid container located higher than the device flows by gravity via a venous side of the system into a reservoir and flows onwards into a blood pump located at the lower end of the reservoir, wherein a first controllable valve (HC1) for a venting line of a filter is opened and, after the response of an upper filling level sensor in the reservoir, is closed. An upper level of the filter is positioned higher than the upper filling level sensor, and a start-stop motion of the blood pump is performed, as a result of which a stepped flooding of the filter is made providing for an advantageous de-airing of the device.

An RFID interrogation probe (1) comprises a ring shaped housing (2), having a maximum thickness (I) (measured along its cylindrical axis) which is less than the innermost diameter (di) of the housing, and a looped antenna (3) housed within the ring shaped housing.

A coupling device configured to form a sample access assembly is provided. The sample access assembly is configured to house a sample. The coupling device includes a heating component and a separating component. Further, the separating component is configured to separate portions of first and second containers that form first and second compartments of the sample access assembly. Moreover, the heating component is configured to heat at least a portion of the sample.

This disclosure describes a combined autologous biologic and cold therapy treatment for treating various skin injuries. The treatment may include applying autologous blood components, including but not limited to platelet rich plasma, to a skin injury in a manner that influences the healing process. A tray assembly for freezing autologous blood components includes a tray body and a plurality of compartments formed in the tray body. Each of the plurality of compartments is configured to receive an individual dose of an autologous blood component.

This disclosure relates to scale-down systems for freezing and thawing aqueous liquid mixtures of thermo sensitive substances. In at least one aspect, the system can comprise a first container that has a head-space and a liquid-space, with a substantially constant average transversal cross-section area in the liquid-space that does not change substantially with height. The first container holds a volume of liquid for a height of liquid, has a lateral active heat transfer area having an insulated lateral area ALIM, and has an equivalent radius sized to reproduce the equivalent radius of a second container. The first container further has a lateral heat transfer area in contact with the liquid-space. The first container is smaller than the second container, and the insulated lateral area is equal to or greater than the lateral active heat transfer area.

Disclosed herein are systems and methods for preparing a plurality of containers having a suspension of a solid wherein the concentrations of the solid in the plurality of containers are substantially similar or the same and the volumes of the suspension in the plurality of containers are substantially similar or the same.

The invention relates to a low temperature indicator mixture for indicating/monitoring a temperature transition within a temperature range of between 20 C. and 160 C., which comprises at least one dye, e.g. oil red, methyl rot, brilliant green, rhodamine B, and at least one alcohol selected from the group that comprises octane-1-ol, nonan-1-ol, propane-1,2-diol, propane-1,3-diol, butane-1,2-diol, butane-1,3-diol, butane-2-ol, pentane-1,5-diol, pentane-1-ol, cyclopentanol, benzyl alcohol, wherein the melt temperature of the mixture is within the aforementioned temperature range. Further aspects of the invention relate to devices and methods for indicating/monitoring a temperature transition within the aforementioned temperature range, in which devices and methods the aforementioned low temperature indicator mixture is used. In a specific embodiment, a device of this kind comprises at least the following components in at least one closed space: a) a partial region, which is at least partially filled with an indicator mixture as defined above; b) a second partial region, which is at least partially filled with an absorbent material, said material being optionally separated from the indicator mixture by a separating element; and c) optionally means to penetrate the separating element to bring the indicator mixture in a liquid state into contact with the absorbent material. In a method according to the invention for temperature monitoring using a device of this kind, a check is carried out to determine whether at least part of the indicator mixture was absorbed by the absorbent material, which indicates an at least temporary increase in the temperature of the device to at least the melt temperature of the indicator mixture.
