Abstract: In a cell culture device, a fluid mechanism for branching a liquid appropriately in its flow passage when the liquid is injected to a plurality of culture vessels in a set and feeding equal amounts of the culture broth to the culture vessels at the same time is provided. In a culture vessel set in which one or plural recess portions are provided so that one or plural culture vessels can be contained in alignment, in view of space efficiency, m×n (row×column) pieces of culture vessels can be set in a matrix type. By using a pump, the culture broth is branched by a multi-way valve for distributing the liquid in an appropriate amount from a tank containing the culture broth, and the liquid is fed at the same time to the plurality of culture vessels in the culture vessel set.

Abstract: A temperature regulating member for avoiding a deterioration in heat radiating output efficiency and deterioration in buffering occurring due to a non-uniform heat distribution within the heat storage material. Heat non-uniformities within the heat storage material are eliminated by inserting one or multiple agitating tools inside the heat storage material by generating an agitating current occurring due to use of agitator tools whose relative positions change within the heat storage material during shipping.

Abstract: A conventional method of retrieving spheroids formed needs to chemically label the spheroids and may physically damage the spheroids. An apparatus according to the present invention has a nanopillar cell culture sheet, a flow speed generating section, and a spheroid retrieval section. The present invention uses the nanopillar cell culture sheet to provide a mechanism that first forms spheroids, a mechanism that provides a flow speed to the spheroids formed, and a mechanism that retrieves the spheroids released owing to the provided flow speed, without the need for labeling.

Abstract: A cell culture apparatus is provided in which a plurality of culture vessels can be mounted and removed in a set, which has a regulation mechanism that can fix each culture vessel in the correct position, and which enables suppression of production costs. The cell culture apparatus has one or a plurality of concave portions, and can arrange and accommodate one or a plurality of culture vessels in the concave portions. Spring-type fixing devices are provided in the depth direction and the width direction, respectively, in each concave portion. The two spring-type fixing devices press against side surfaces of the culture vessel to fix the culture vessel in the culture vessel set. At this time, by pressing against the culture vessel at two points, the position of the culture vessel at the time of fixing can be maintained with good accuracy.

Abstract: The invention provides a culture apparatus capable of setting preferable environments for each element of a small-sized culture chamber and manipulator, allowing an automatic culturing operation. The culture apparatus according to the invention is provided with a first chamber and a second chamber being a culture chamber. A device for producing moisture is arranged only within the second chamber. Accordingly, a difference between the humidity environment of the first chamber and that of the second chamber can be produced, and thus a manipulator arranged outside the second chamber, accessible to the second chamber can be prevented from being adversely affected by moisture.

Abstract: A temperature regulating member capable of avoiding deterioration in heat dissipation efficiency of a heat-accumulating material, and deterioration in a buffer function thereof, due to ununiformity in heat distribution inside the heat-accumulating material. With the use of a churning flow occurring by disposing one piece of stirrer or plural stirrers inside the heat-accumulating material, and by causing a relative position of the stirrer, inside the heat-accumulating material, to be changed during transportation, it is possible to eliminate ununiformity in heat distribution inside the heat-accumulating material. The temperature regulating member has a feature in that a phenomenon of a peripheral part of the heat-accumulating material being first cooled to be subsequently solidified is avoided, thereby enabling the heat dissipation efficiency and the buffer function to be maintained.

Abstract: The present invention enables to keep the culture vessel clean with the clean air without touching the open air in which floating bacteria exist, and to culture cells with taking in and out the culture apparatus under the environment with low damages for the cells in constant temperature. The present invention is the culture vessel box which has one or more culture vessels, has the heater, and has the door outside which the good adhesive resin film is stuck, the culture apparatus which has various apparatuses including a heater and culture cells, and has the door outside which the resin film is stuck similarly to the culture vessel box and has its storing chamber.

Abstract: For stopping bleeding at an incensed wound, quickly, with using a medical manipulator system, having a plural number of manipulators therein, the medical manipulator system comprises manipulators, each having an operation tool, respectively. Onto the operation tools is applied current, alternately, from a positive electrode of a bipolar electric power source. Onto the other operation tool is applied current from a negative electrode of the bipolar electric power source. Driving the operation tool cauterizes a portion of an affected portion, thereby stopping bleeding in a wide region.
