Abstract: A sample processing apparatus according to the present embodiment includes an apparatus body. In the apparatus body, a cartridge for internally performing processing on a cell is installed, and the apparatus body controls liquid feeding in the cartridge and/or adjusts an environment in the cartridge. The apparatus body includes processing circuitry configured to detect an inclination of the cartridge with respect to a horizontal plane and/or the apparatus body.

Abstract: A cartridge used for cell preparation or cell processing includes a first container configured to store a liquid; an air filter arranged at an opening; a first passage connected to the first container and the opening and configured to allow the liquid suctioned from the first container to flow in; a second passage connected to the first passage and the opening and configured to allow the liquid to flow in from the first passage; and a second container connected to the second passage and configured to allow the liquid to flow in from the second passage if the first passage is pressurized with the liquid having flown into the first passage.

Abstract: A cell production cartridge according to an embodiment includes a flow path configured to deliver liquid or gas to be used for producing a cell. In a transport path for the liquid or the gas, the flow path includes a pressure loss generating part structured so that a cross-sectional area of the liquid or the gas delivered through the flow path is smaller than cross-sectional areas before and after the pressure loss generating part.

Abstract: A cell handling system includes: a cell handling cartridge including a passage and an inlet, the passage configured to allow a liquid to flow through the passage, the inlet provided to the passage, and configured to allow a gas to pass through the inlet; a body apparatus including a connection portion and a presser, the connection portion being connected to the inlet and having an air passage configured to allow the gas to flow through the air passage, the presser being configured to press the connection portion against the cell handling cartridge; and a seal member on at least one of an opposing face of the connection portion or an opposing face of the cell handling cartridge, the opposing face of the connection portion facing the cell handling cartridge, the opposing face of the cell handling cartridge facing the connection portion.

Abstract: According to one embodiment, a white blood cell collection apparatus includes a first container, a second container, a filter, a branching portion, and a controller. The controller controls liquid delivery operation through the branching portion. The liquid delivery operation includes: sending blood in the first container from the branching portion to the filter to cause the filter to capture white blood cells contained in the blood; pushing back the blood remaining in the branching portion toward the first container by sending the wash liquid in the second container from the branching portion toward the first container after the capturing; and washing the filter by sending the wash liquid in the second container from the branching portion to the filter after the pushing back.

Abstract: According to one embodiment, a cell production cartridge includes a flow channel and a container for accommodating the flow channel. The container includes an energy transmission member for receiving, from outside the container, energy for sending a liquid within the flow channel. The energy transmission member is located at a boundary between an inside and an outside of the container.

Abstract: A method for manufacturing a fixing member having a substrate, an elastic layer on the substrate, and a release layer on the elastic layer, having a thickness of 15 ?m or more and 25 ?m or less, and containing a fluororesin includes (1) providing a coating solution, containing: the fluororesin having a melt flow rate (MFR) of 1 g/10 min or more and 3 g/10 min or less, and an acrylic resin; (2) forming a coating film of the coating solution on the elastic layer; and (3) baking the coating film to melt the fluororesin therein, covering a surface of the elastic layer with the melted fluororesin, and forming the release layer.
