A blood collection device comprising formed additive particles. The additive particles are an improvement over available additive formulations that are powder blended in that the components of the additive particles of the present invention are in each formed particle. The formed additive particles comprise a fluoride salt and an ethylenediaminetetraacetate salt or a heparin salt to consistently minimize glycolysis and coagulation of a blood specimen with low hemolysis.

Apparatus for inhibiting glycolysis in blood samples

A pad assembly for use in a microorganism culture test is provided which comprises, in sterile conditions, a water-absorbing pad which is impregnated with a culture medium for culturing given microorganisms and dried, a filter member bonded to the upper surface of said water absorbing pad and having submicron pores of a size capable of substantially preventing the microorganisms from passing therethrough, and a coating of an antibiotic deactivating agent applied to the upper surface of said filter member or to the common surface between said filter member and said water-absorbing pad, as well as testing apparatus having the pad assembly mounted in a vessel. The invention eliminates the adverse effect of antibiotics in a sample to be tested which will otherwise inhibit the growth of microorganisms in the sample to adversely alter test results.

Multi-layer microorganism culture testing apparatus

Disclosed is a method for centrifuging serum which comprises steps of introducing a barrier having an elastic porous member at least at its principle part into a blood-collecting tube and centrifuging serum, the elastic porous member having porosity of 40% or more, continuous-pore size of 50 to 400 .mu., and a cross section larger than that of the blood-collecting tube. Also disclosed is a barrier to be introduced into a blood-collecting tube, comprising an elastic porous member having porosity of 40% or more, continuous-pore size of 50 to 400 .mu., and a cross section larger than that of the blood-collecting tube, the bottom portion of the elastic porous member preferably being a relatively hard portion with smaller outside diameter.

Method for separating blood and a barrier device therefor

A protector for enclosing the needle body of a sampling needle after collection of blood or coeliac liquid comprises a cylindrical member having a hydrophilic inner wall and whose base end is opened, the inner wall of said opening being so shaped as to ensure engagement with the hub of the sampling needle; and a seal material filled in the cylindrical member for embedment of at least the end opening of the sampling needle therein.
