PROBLEM TO BE SOLVED: To provide an arterial blood collecting apparatus capable of omitting or reducing (moderating) the measure for preventing moisture absorption with excellent solubility and miscibility to blood of an anticoagulant and having high production efficiency. SOLUTION: This arterial blood collecting apparatus 1 comprises an outer cylinder 2, a gasket 3 slidable within the outer cylinder 2, and a plunger 4 for moving operating the gasket 3. An air permeable filter member 35 is installed to the tip part of a hole 32 formed on the gasket 3. The hole 32 can ventilate air to the outside through a hole 42 and internal space 43 formed on the plunger 4. An anticoagulant supplying piece 5 is housed in the space 26 enclosed by the outer cylinder 2 and the gasket 3. The anticoagulant supplying piece 5 has the function of supplying an anticoagulant 52 to the collected blood, and it supports the anticoagulant 52 as heparin, for example, on one side or both sides of, for example, a hexagonal sheet-like support 51. |
