摘要:
A valve body is formed from an elastic member in the form of an elliptic or circular film (disk shape) having an upper face and a lower face. The valve body has an opening and closing section which is opened and closed in response to insertion and pulling out of a dilator and is formed from a first slit, a second slit, a second concave portion and two third concave portions. A pair of ribs and six projections are formed on the lower face side of the valve body. The ribs are disposed in opposing relationship to each other with the second slit interposed therebetween and extend along the lower face. Further, the projections are disposed such that they are positioned on the inner side of the ribs and are opposed to each other with the second slit interposed therebetween.

The valve body further has an opening and closing section which is opened and closed in response to insertion and pulling out of a dilator and is formed from a first slit, a second slit, a second concave portion and two third concave portions. The second concave portion is formed at a portion of the concave surface side of the valve body corresponding to an intersecting portion, and the third concave portions are formed at the opposite end portions of the first slit. The second concave portion extends, in a thickness wise direction of the valve body, to an intermediate portion of the first slit but not to the second slit.

There is provided an agent for reducing body fat, comprising as an active ingredient a dioxabicyclo[3.3.0]octane derivative represented by formula (I): wherein R1 to R6 each independently represent a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, provided that R1 and R2 and/or R4 and R5 combine together to form a methylene or ethylene group; and n, m, and l are each 0 or 1.
摘要:
In sampling a blood specimen inside a blood-collecting tube equipped with a film stopper at an opening thereof, a needle capable of sampling a blood component is made to pierce the film stopper and the tip of the needle is situated in the blood specimen. The blood specimen is sampled via the needle while the interior of the blood-collecting tube is kept cut off from the exterior thereof.

A blood sample tube holder for holding a blood sample tube includes a holder body having a needle joint on one end for connection to a blood sample collecting needle, the holder body having an open opposite end. The holder body has a plurality of elastic and flexible lands on an inner wall surface thereof. The lands have radially innermost surfaces arranged such that when the blood sample tube is inserted into the holder body through the open opposite end, the lands are engaged and elastically deformed by the blood sample tube for an increased area of contact with the blood sample tube for holding the blood sample tube in the holder body.
