Abstract: A culture device supplying an accurate amount of liquid into a culture bag has a culture bag having ports, a first bag holding portion having supporting surfaces supporting the culture bag, a rotation mechanism rotating the first bag holding portion, a liquid supplying mechanism supplying a liquid through a tube communicating with the ports a weight detector detecting the weight of the culture bag and the first bag holding portion, and a control portion, in which the control portion sets a first reference value according to a first detection information output from the weight detector in a first state and carries out a liquid supplying step of stopping the liquid supplying mechanism under the condition where a second detection information output from the weight detector when a liquid is supplied to the culturing bag reaches a first target value obtained by adding the weight of the liquid to be supplied to the first reference value.

Abstract: A means capable of simply and efficiently concentrating a cell suspension. A concentrator has a culture vessel having a first port and a second port, a server bag having a port, a case having a hollow fiber bundle in the internal space, a filtering device having an inlet port, a first outlet port, and a second outlet port, a collection vessel having a port, a liquid supply circuit connected to the first port, the inlet port, and the server bag's port so that flow passages are switchable, a liquid discharge circuit connected to the second port, the first outlet port, the second outlet port, and the collection vessel's port so that flow passages are switchable, a liquid supply mechanism having a switching mechanism, a supply pump, and a discharge pump, and a rotation mechanism rotating the filtering device.

Abstract: To prevent a user from accidentally pricking the user with a hollow needle when separating blood components using a syringe and a connection device. A blood component separation apparatus has three syringes and a connection device. The connection device is attached to one syringe and is inserted into other syringes. The connection device has a first member to which a base end of a hollow needle is joined and a second member which is connected to the first member in such a manner as to be able to move relative to the first member. The second member is moved back and forth between a first position where a tip of the hollow needle is accommodated and a second position where the tip of the hollow needle is exposed. The second member has elastic portions which are elastically deformed in the movement from the first position to the second position. The elastically deformed elastic portions elastically energize the second member at the second position to the first position side with respect to the first member.

Abstract: Provided is a platelet-rich plasma separator which can carry out the separation of a platelet-rich plasma with a small number of gamma radiation sterilized instruments and a platelet-rich plasma separation method. The platelet-rich plasma separator comprises a first syringe and a second syringe. The first syringe comprises a first syringe cylinder provided with a first port on which a blood collection needle can be mounted, a first cap detachable from the first port, a first gasket for sealing the first syringe cylinder fluid-tightly, which first gasket is reciprocated within the first syringe cylinder, and a first plunger provided detachably on the first gasket.

Abstract: A filter set for recovering desired blood components from human blood and a method for recovering blood components using the filter set are provided. The filter set includes a bag body and an accommodation vessel for accommodating the bag body therein in a compressed condition. In the method the bag body is provided in the accommodation vessel and is compressed and blood is passed through the compressed bag body. Blood components are adhered to the compressed filter material in the bag body. Thereafter, the compression of the bag body is relieved and a washing solution is passed through the expanded bag body to remove the blood components contained therein.
