The present invention provides a biological tissue cutting device that can produce minute fragments of a biological tissue easily and efficiently. The biological tissue cutting device for producing tissue fragments by cutting a biological tissue includes: a first cutting unit configured to form a cut surface extending in a first direction by cutting the biological tissue on a stage; and a second cutting unit configured to form a cut surface extending in a second direction and a cut surface extending in a third direction by cutting the biological tissue on the stage. The planar direction of the cut surface extending in the second direction is a direction crossing the cut surface extending in the first direction, and the planar direction of the cut surface extending in the third direction is a direction crossing the cut surface extending in the first direction and the cut surface extending in the second direction.

Biological tissue cutting device and use thereof

A surgical tool has a body including a pair of legs, each leg having a leading edge and a butt end. The pair of legs are connected at their butt ends, wherein the pair of legs are configured to come close and depart at the leading edges. A deformable connecting member connects the pair of legs to one another at the leading edges.

Surgical tool for anastomosis

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.

Container for preparing serum and regenerative medical process using the same

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 separatorfor separating collected blood into a plurality of blood components and preserving them, the separatorincluding a blood reservoirfor reserving the blood and a component storage partaseptically connected in an air-tight manner to this blood reservoir, to the aforementioned blood reservoirbeing 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 partstoring each blood component generated by separation of the blood in the blood reservoir

A catheter lock solution which is a catheter lock preparation having a bacteriostatic property at physiological osmotic pressure without practically containing a bacteriostatic component such as a preservative, an antimicrobial agent, or an antibiotic and having high safety, characterized in that the preparation contains a weak acid having an acid dissociation constant (pKa) of 3.0 to 6.5 as a buffer, a pH of the solution is less than 6.0, preferably from 3.0 to about 5.5, an osmotic pressure ratio is from 0.5 to 3.0, and a pH change (variation) can be suppressed to less than the 6.0 with the weak acid, and a container containing the catheter lock solution.

Intravascular indwelling catheter lock solution containing weak acid and container containing the same

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.
