摘要:
Provided are: a device that is for separating/housing blood components and that can more easily and aseptically separate/house platelet-rich plasma; and a method for preparing platelet-rich plasma. The device (1) for separating/housing blood components is provided with: a blood storage section (2); a component housing section (3) for housing a component that is part of blood; and a linking tube (4) that joins the blood storage section (2) and the component housing section (3). The blood storage section (2) has: a tube-shaped blood storage vessel (21) that is flexible; a blood lead-in pathway (27) that leads blood into the blood storage vessel (21); and a component lead-out pathway (28) that leads out a component that is part of blood from the blood storage vessel (21). The component housing section (3) has: a component lead-in pathway (37) that leads in a component that is part of blood led out from the blood storage vessel (21); and a metal needle (371) that extends from the component lead-in pathway (37) towards the interior space of the component housing section (3) and can return the component that is part of blood housed in the component housing section (3) towards the blood storage vessel (21).

A double male connector (1) includes a first male luer (10) on one end and a second male luer (20) on the other end. The first male luer (10) and the second male luer (20) are in communication with each other. An outer circumferential surface of the first male luer (10) constitutes a first tapered surface (12) whose outer diameter decreases toward a leading end of the first male luer, and an outer circumferential surface of the second male luer (20) constitutes a second tapered surface (22) whose outer diameter decreases toward a leading end of the second male luer. A tubular portion (15) surrounds the first male luer (10). A female screw (16) is formed on an inner circumferential surface of the tubular portion (15).

An infusion set (1) includes a first flow channel (10) constituted by a pliable tube (10a) and including a spike (11) provided at one end thereof, a second flow channel (20) constituted by a pliable tube (20a) and including a lock connector (50) provided at one end thereof, the lock connector (50) including a lock mechanism (60) that is brought into engagement with a female connector (200), a third flow channel (30) constituted by pliable tubes (30a, 30b and 30c) and including a male connector (31) provided at one end thereof, and a three-way stopcock (40) to which another end of the first flow channel, another end of the second flow channel and another end of the third flow channel are connected. The three-way stopcock includes a handle (41) that can be switched between a first position that brings the first flow channel and the third flow channel into communication with each other and a second position that brings the second flow channel and the third flow channel into communication with each other.

摘要:
An outer unit (101) includes a shield (20) that has an inner cavity (24) and a soft outer needle (30) that is fixed to a front end of the shield. An inner unit (102) includes an inner hub (40) that is disposed within the inner cavity of the shield, a hard inner needle (50) that is fixed to a front end of the inner hub, and a tube (60) that is connected to a rear end of the inner hub. The inner unit is displaceable relative to the outer unit from an initial position at which the inner needle penetrates the outer needle and protrudes from a leading end of the outer needle to a retracted position at which the inner needle is housed within the inner cavity of the shield. The inner unit located at the initial position is fastened to the outer unit so that the inner unit is prevented from moving toward the retracted position due to a reaction force that is exerted on the inner needle during insertion with the inner unit being disposed at the initial position.
