The device for separating/housing blood components is provided with: a blood storage section; a component housing section for housing a component that is part of blood; and a linking tube that joins the blood storage section and the component housing section. The blood storage section has: a tube-shaped blood storage vessel; a blood lead-in pathway; and a component lead-out pathway. The component housing section has a component lead-in pathway and a metal needle.

Abstract: A blood storage container suitable for quick and efficient production of a large amount of serum while ensuring high safety, and a method of separating blood and a regenerative medical process using the same are provided. A blood component separation storage apparatus is provided for separating a plurality of blood components of blood so as to be stored therein. The blood component separation storage apparatus includes a blood reservoir for holding the blood and a component storage part connected to the blood reservoir aseptically and in an air-tight manner. The blood reservoir contains an anticoagulant which suppresses coagulation of the blood. The blood reservoir has a serum producing function to remove coagulation factors from the blood to an extent enabling use in practical applications as a serum, and the component storage part stores each blood component generated by separation of the blood in the blood reservoir.

Abstract: A blood storage container suitable for quick and efficient production of a large amount of serum while ensuring high safety, a method of separating blood and a regenerative medical process using the same, and a serum preparation apparatus are provided. A blood component separator is provided, which separates collected blood into a plurality of blood components and preserves them, and includes a blood reservoir and a component storage part aseptically connected in an air-tight manner. The blood reservoir has a serum producing function to remove coagulation factors from the blood. The component storage part stores each blood component in the blood reservoir. The serum preparation apparatus includes an indwelling needle, a catheter having one end connected to a base end side of the indwelling needle, a syringe capable of storing blood connected to another end of the catheter, and a blood coagulation accelerating substance stored in the syringe.

Abstract: A blood storage container suitable for quick and efficient production of a large amount of serum while ensuring high safety, and a method of separating blood and a regenerative medical process using the same are provided. In a blood component separator 1 for separating collected blood into a plurality of blood components and preserving them, the separator 1 including a blood reservoir 10 for reserving the blood and a component storage part 20 aseptically connected in an air-tight manner to this blood reservoir 10, to the aforementioned blood reservoir 10 being imparted a serum producing function to remove coagulation factors from the blood to an extent enabling use in practical applications as a serum, and the aforementioned component storage part 20 storing each blood component generated by separation of the blood in the blood reservoir 10.

Abstract: A liquid component collecting device capable of more easily collecting a liquid component. A liquid component collecting device (100) is provided with: a flexible cylindrical liquid component storage container (21) having an opening at one end thereof; a cylindrical first housing container (22) for housing the liquid component storage container (21) and having an opening at one end thereof; and a first cap (23) connected to the opening in the liquid component storage container (21) and fitted to the opening in the first housing container (22). A pressure regulating space (26) independent of the internal space of the liquid component storage container (21) is formed between the outer side of the liquid component storage container (21) and the inner side of the first housing container (22).

Abstract: It is intended to provide a serum which contains a large amount of growth factors capable of efficiently promoting the growth of stem cells. A human serum for cell culture which shows a residual ratio of platelets remaining within 20 minutes after blood collection in relation to the whole amount of the platelets is 0% to 20%, and a release ratio of cell growth factors is 20% to 100%.

Abstract: A method for preparing serum and a serum preparation apparatus is provided that can give a large amount of serum with high culture efficiency regardless of freshness of blood used. In a method for preparing serum from blood containing at least platelets, a platelet processing step is provided in which platelet membrane in the blood is destroyed. After the platelet processing step, a deposition step for depositing thermolabile protein in blood and a removal step for removing the thermolabile protein, which has been deposited in the deposition step, are preferably provided.

Abstract: A clip which solves a technical problem that the latching of the clip is not easily released by the external force caused by falling, etc., and is easily released when the clip is used. The clip has opposed clipping arms capable of forming an independent and separate space by pressing and holding a clipped object constituted of a flexible hollow member between them. The clip has a latching means on one end of the opposed clipping arm, which has a latching part capable of latching the clipping arms. The clip further has a latching releasing means capable of releasing the latching by an external force headed to an external direction from the clipping arm. The latching means has a supporting point part acting the latching releasing force, added to the latching means by the latching releasing means, to the direction to release the latching of the latching part.
