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.

A liquid component collecting device capable of more easily collecting a liquid component. A liquid component collecting device () is provided with: a flexible cylindrical liquid component storage container () having an opening at one end thereof; a cylindrical first housing container () for housing the liquid component storage container () and having an opening at one end thereof; and a first cap () connected to the opening in the liquid component storage container () and fitted to the opening in the first housing container (). A pressure regulating space () independent of the internal space of the liquid component storage container () is formed between the outer side of the liquid component storage container () and the inner side of the first housing container (). The first cap () is provided with a liquid component inlet channel () for introducing blood into the liquid component storage container (), a first communication channel () communicating with the internal space of the liquid component storage container (), and a second communication channel () communicating with the pressure regulating space ().

Liquid component collecting device

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%.

Human serum for cell culture

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.

Method for preparing serum and serum preparation apparatus

It is intended to provide an apparatus for separating and storing blood components which facilitates the preparation of serum. An apparatus () for separating and storing blood components which comprises a blood pooling part () for pooling a fluid at least containing liquid components containing a blood-origin coagulation factors and platelets, a component storing part () for storing at least a part of the components of the fluid pooled in the blood pooling part (), and a connector part () aseptically connecting the blood pooling part () to the component storing part (), wherein the blood pooling part () comprises a blood pooling container () in the form of a flexible tube, a fluid inlet channel () for introducing the fluid into the blood pooling container () and a component outlet channel () for leading out at least a part of the components of the fluid; the component storing part () has a component inlet channel () for introducing at least a part of the components of the fluid having been led out from the blood pooling container (); and the connector part () connects the component outlet channel () to the component inlet channel ().

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.

Clip for dividing two liquids

A medical fluid passage switching apparatus comprising: at least, a rotatable shaft F; a cam C which is rotated in relation to the rotating movement of the shaft F to close and open divided tubes for determining a passage of a fluid; and a housing L having tube accepting holes I and so arranged to enable the holding of the cam C, is provided. More particularly, provided are such a medical fluid passage switching apparatus in a continuous ambulatory peritoneal dialysis (CAPD) system and a tube which is decreased in the diameter and/or thinned in the wall at a region where the cam or a combination of the cam and the clamp is engaged for closing and opening.

Fluid passage change-over apparatus for medical treatment

An automatic exchanger apparatus for peritoneal dialysis fluids is provided having a dialysis fluid bag and a drained fluid bag and arranged for connecting and disconnecting between the end of a peritoneal dialysis circuit equipped with a branching point and the end of a tube extending from a patient to drain the waste dialysis fluid from the cavity of the patient and fill the peritoneal cavity of the patient with a fresh peritoneal dialysis fluid for exchange, and in particular comprises: means A, B, and C for carrying out respectively a step (A) of connecting the end of the patient side tube to the end of the peritoneal dialysis circuit, a step (B) of delivering and draining the waste fluid, and a step (C) of, disconnecting the two ends and connecting the end of the patient side tube to its shut-off member, arranged for carrying out their respective steps (A) and (C) automatically; and a controlling means for controlling the respectively means to execute their respectively steps in a sequence. The apparatus is simple in the construction while carrying out, with much ease, the connection and disconnection of the tubes and the exchange of the fluids including a waste and a fresh supply one, hence avoiding operational errors of the operator and minimizing the possibility of infection and contamination.
