A liquid collecting tube for receiving blood or liquid for inspection is disclosed, which has a tubular member and a closure member for closing an open end of the tubular member and made of a material capable of being pierced by a piercing needle. The closing member includes a sealing member for holding the open end of the tubular member sealed when taking out the liquid form the tubular member with a take-out tool and a separable member separablly laminated on the outer side of the sealing member. The separable member is removed so that only the sealing member remains on the tubular member when taking out liquid. The sealing member is film-like and can be readily broken by the take-out tool such as a pipette.

Liquid collection tube

A blood collection tube includes a bottom and an open end that is hermetically sealed by a plug. A supporting film having an anticoagulant coated thereon is positioned within the tube. The anticoagulant-coated surface of the supporting member is provided with a large number of fine convexes.

Blood collection tube

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.

Method for sampling blood specimen

Blood collecting tube

Blood collecting tube holder

A liquid collection tube for collecting blood or like liquid with a liquid collection needle, comprises a tube member with a bottom and a cap member removably fitted on an open end of the tube, with thread structures. A sealing member is interposed between the cap member and open end of the tube member to enhance the close contact between the two. The sealing member is not bonded to the open end of the tube member, and it can be removed together with the cap member to open the open end of the tube member when the cap member is removed from the tube member. The cap member has a through hole permitting a re-sealing member of the sealing member to be pierced from the outside.

A film-like closure opener opens a film-like closure such as a cap or lid which closes an open end of a bottomed tubular container such as a blood collecting tube. The film-like closure opener includes a cutter having a circular cutting edge for cutting off at least a substantial portion of the film-like closure along the open end of the tubular container. The opener may have a needle for piercing an elastic member on the film-like closure, so that the cut-off closure can be removed with the needle. The opener also has a gripper which is manually held and pushed to force the cutter into the tubular container while cutting off the film-like closure.

Device for opening film-like closure

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.

Holder for blood sample tube

A blood collecting tube comprises a tubular member made of synthetic resin which has an open end and a closed bottom, and a closure member which is for closing the open end of the tubular member and allows a puncture needle to pierce therethrough, the interior of said blood collecting tube being kept under reduced pressure, said tubular member being essentially made of a polyester resin mixture of a polyester resin mainly based on a ethylene glycol and terephthalic acid and a polyester resin mainly based on ethylene glycol and isopthalic acid. The tubular member of this blood collecting tube can be suitably made by injection molding and has high gas barrier properties so that the capability of collecting blood decreases little with time.
