PROBLEM TO BE SOLVED: To reduce a waste to be treated to the minimum by placing a liquid drip and smearing it on a glass by a dripping device and distributing it. SOLUTION: A dripping device 3 is placed and engaged to an edge part which is closed by a screw cap 4 of a test tube 5 for housing such liquid as blood. The cap 4 is provided with an annular addition part 6 which becomes an extension of the test tube and an elastic closing plug 7 inside and the closing plug 7 is penetrated by a dripping needle 8 with a passage 9 in longer direction at the time of the placement and engagement. A liquid cylinder 1 passes through these and reach a placement glass 2. A smearing means 10 is provided in one piece with the dripping device 3, a means 10 is formed in a form so that a smearing web protruding in radius direction is provided at the edge part at a part away from the addition part 6 of the device 3 and is provided with a smearing edge part 11 for distributing the liquid cylinder 1 on the glass 2, thus the device 3 can perform smearing operation in addition to dripping and hence causing only the device 3 to contact the liquid cylinder 1 and only this part to become a special waste. |
