Patent number: 10639625Abstract: A pipette tip includes a body and projections. In the body, a flow passage in which liquid from the syringe flows and an ejection opening that ejects the liquid, which has flowed through the flow passage, to the outside are formed. The ejection opening is formed in a distal end portion. The projections are provided on the distal end portion and protrude from a region around the ejection opening in the ejection direction of liquid. The projections are partially disposed around the central axis of the body. Even in a case where a residual droplet adheres to the ejection opening, the residual droplet does not adhere to an injection opening of a sample container, because the projections guard a region around the residual droplet.Type: GrantFiled: March 23, 2018Date of Patent: May 5, 2020Assignee: FUJIFILM CorporationInventors: Toshiaki Kuniyasu, Toshihito Kimura, Tomonori Nishio, Kazuteru Nishijima

Patent number: 10420876Abstract: A storage portion forming a storage space 10, includes an inclined inner wall portion 20 that is connected to a base portion so that the diameter of the inclined inner wall portion gradually decreases; a concave portion 22 is formed at a part of the inclined inner wall portion; and the concave portion 22 includes a concave portion side surface 22b that is connected to a concave portion bottom surface 22a. The concave portion 22 is formed at a position, where the concave portion crosses an interface S between the specimen centrifuged during rotation and air, in a radial direction with respect to the central axis; and the maximum width of the concave portion 22 in a circumferential direction around the central axis is included in a range of 2 mm to a length of 20% of the whole circumference.Type: GrantFiled: September 19, 2016Date of Patent: September 24, 2019Assignee: FUJIFILM CorporationInventors: Tomonori Nishio, Kazuteru Nishijima

Publication number: 20160100786Abstract: There is provided an adapter for blood sample dispensing which enables change of the presence and absence of a medicine to be mixed in a blood sample or the type of the medicine thereof while suppressing contact of blood with the air, during preparation of an examination sample, and a dispensing kit and a needle kit provided therewith. Dispensing is performed using an adapter 1 for blood sample dispensing which is mounted on a distal portion of a syringe and has a piping structure, in which the adapter has a fitting portion 3 fitted to the distal portion at one end, a nozzle portion 2 at the other end, and a flange portion 4 on an outer circumference surface, and in which the adapter 1 has a medicine 5, to be mixed in the blood sample S, on the inside of the nozzle portion 2.Type: ApplicationFiled: December 17, 2015Publication date: April 14, 2016Applicant: FUJIFILM CorporationInventors: Tomonori NISHIO, Toshihito KIMURA, Toshiaki KUNIYASU, Kazuteru NISHIJIMA
