A device for administering an infusion or transfusion of liquid from a container includes a pump for pumping liquid to a patient connection via a conduit having a liquid-retaining filter membrane. The device also includes a pressure measuring device for acquiring measurement values corresponding to a pump-inlet-side pressure, and a control device for detecting a change in the pump-inlet-side pressure based on the measurement values. The control device determines, based on the change in the pump-inlet-side pressure, whether to stop pumping. The control device also generates a control signal when the pumping is to be stopped. Moreover, the control device emits, based on the control signal, a communication signal to a data connection between the device and a unit that reads the communication signal. In addition, or in the alternative, the control device switches the device from a first state to a second state based on the control signal.

A blood processing filter includes a container having 2 ports respectively functioning as an inlet for a liquid to be processed and as an outlet for the processed liquid, and a filtration medium filled in the container, wherein an airflow resistance of the filtration medium is 55.0 kPa.Math.s/m or more and less than 85.0 kPa.Math.s/m, the filtration medium includes a filter material A having an airflow resistance per unit basis weight of 0.01 kPa.Math.s.Math.m/g or more and less than 0.04 kPa.Math.s.Math.m/g and a filter material B having an airflow resistance per unit basis weight of 0.04 kPa.Math.s.Math.m/g or more, at least a part of the filter material A is disposed on a side closer to the inlet for a liquid to be processed than the filter material B, and a sum of airflow resistances of the filter material A is 6.0 kPa.Math.s/m or more.

A blood filtration system may include a blood circuit. The blood filtration system may include an adjustable cuff configured to receive a portion of a limb of a patient. The cuff may selectively engage with the limb to apply an external force to the limb. Applying force to the limb with the cuff may inhibit flow of blood within the vasculature of the limb. The system may adjust the cuff to change the force applied to the limb, for example to correspondingly change flow of blood from the vasculature to the blood circuit. The blood filtration system may include a controller. The controller may communicate with the cuff. The controller may operate the cuff to adjust the force applied to the limb of the patient.

A device for extracorporeal blood circulation includes a potted body having an oxygenator module including at least two of a plurality of circular hollow fiber mat layers, a heat exchanger module including at least two of the plurality of circular hollow fiber mat layers, a blood inlet port adjacent a first end of the potted body and a blood outlet port adjacent a second end of the potted body. The device includes a gas inlet and outlet port and a fluid inlet and outlet port. A first of the plurality of hollow fiber mats includes a plurality of hollow fibers aligned in a direction that is angled relative to a direction of alignment of the plurality of hollow fibers of a second of the plurality of hollow fiber mats and, the plurality of hollow fiber mats are aligned to have the same orientation as one another.

An embodiment provides a medical needle unit with an air filter part for preventing air injection, the medical needle unit being designed to prevent qualitative deterioration of ultrasound images due to unexpected air injection in ultrasound-guided procedure and operation environments.

An object of the present invention is to provide a novel filter material and a filter including the same. Specifically, the present invention aims to provide a filter material capable of filtering in a short period of time, without clogging of the filter, while maintaining high cell separation properties, and a filter including the same. More specifically, the present invention aims to provide a filter material in which fiber masses (flocs) are uniformly distributed, and a filter including the same. The present invention provides a novel filter material showing excellent cell separation properties and excellent flow-through properties regardless of design choices for filters known prior to the filing of the present application, and an efficient cell separation method using a novel filter on which the filter material is stacked.

A blood reinfusion system for processing autologous blood for reinfusion into a patient. The system includes a suction container adapted to receive a mixture of autologous blood and impurities and extract the impurities from the mixture, a blood filter assembly adapted to further extract the impurities from the mixture, whereby whole purified autologous blood is obtained, and a blood transfer bag adapted to receive the whole purified autologous blood from the blood filter assembly.

An oxygenator and method for oxygenating blood. The oxygenator includes a housing, an oxygenation chamber, and elongated gas permeable conduits that extend across the oxygenation chamber. The blood flow enters and contacts with exterior surfaces of the conduits and exits the oxygenator to transfer of oxygen from within the conduits to the blood flow and transfer carbon dioxide from the blood flow into the elongated gas permeable conduits. The housing includes a gas inlet and is configured to distribute a gas flow received through the gas inlet to the elongated gas permeable conduits so as to a first portion of the gas flow flows through a first set of the elongated gas permeable conduits in a first direction and a second portion of the gas flow flows through a second set of the elongated gas permeable conduits in a second direction that is opposite to the first direction.
