The base part has a keyed surface configured to interlock with a keyed surface of the pods. A pullcord for retracting the suction pods toward a support tube of the tool has a loosened state wherein the first and second keyed surfaces can be spaced apart so that the suction pods can be spread for grasping a tissue to be stabilized at desired locations. The pullcord has a tightened state wherein the first and second keyed surfaces are interlocked so that the suction pods are inhibited from pivoting.
The present invention provides a suction catheter for veins that is capable of effective suction while suppressing excessive deformation of and damage to a tip section. Provided is a suction catheter (10) for veins comprising an elongate body tube (40) and a tubular distal-end tip (50) which is fixed to the distal-end side of the body tube (40), wherein: the distal-end tip (50) has an inner tapered surface (52) at which the inner diameter decreases toward the distal end and an outer tapered surface (51) at which the outer diameter decreases toward the distal end, and is formed from a resin which is harder than the resin from which the body tube (40) is formed; and a first inclination angle (α), which is the angle at which the inner tapered surface (52) is inclined with respect to the axis of the distal-end tip (50), is less than a second inclination angle (β), which is the angle at which the outer tapered surface (51) is inclined with respect to the axis of the distal-end tip (50).
A cap removal jig (J1) comprises a container-holding member (40) and an engagement member (64A). The container-holding member (40) is capable of holding a plurality of medical containers (14) each having a plurality of container bodies (16). The engagement member (64A) is formed so as to be capable of engaging with a plurality of protective caps (18) respectively attached to the plurality of container bodies (16). The plurality of protective caps (18) can be removed from the plurality of container bodies (16) by displacing the engagement member (64A) relative to the container-holding member (40) in a state in which the engagement member (64A) is engaged with each protective cap (18) of the plurality of medical containers (14).
A medical jig (10) is provided with a holder (16) having an internal space (24), an operation member (18) capable of removing a protection cap (14) of a medical container (12) by employing a cap removal part (181), and a disinfection member (20) capable of carrying out disinfection by bringing a cap disinfection part (201) into contact with a sealing part (123) after the protection cap (14) is removed.
A jig (10A) for a collection kit is provided with: a kit holding part (62) for holding a collection kit (12A); a bottle holding member (64) which is capable of holding a plurality of culture bottles (14); a lifting/lowering mechanism (66) for moving the kit holding part (62) in the vertical direction and in a relative manner; and a rotation mechanism (68) for rotating the bottle holding member (64) about a rotation axis (CL). The bottle holding member (64) has a plurality of bottle support parts (120) that are arranged along the circumferential direction. The rotation mechanism (68) rotates the bottle holding member (64) in conjunction with an approaching operation or a withdrawing operation of the lifting/lowering mechanism (66).
