Abstract: A medical holder for assisting an operation of puncturing a flexible tube includes a first holding member 1 and a second holding member 2. The first holding member 1 and the second holding member 2 are formed so that they can be engaged with each other and can hold the flexible tube 27 therebetween when they are engaged with each other. Furthermore, a hole through which the flexible tube 27 is punctured is formed in the first holding member 1.

Abstract: Filtration equipment is used that includes: a filter 2 for filtering a liquid filling a first container 1; a second container 3 for collecting the liquid that has been filtered through the filter 2; a third container 7; a first line 4 for connecting the first container 1 and the filter 2 to each other; a second line 5 for connecting the filter 2 and the second container 3 to each other; and a third line 6 that branches off from the second line 5 and is connected to the third container 7. The third container 7 is placed above the second container 3, with a part of the third container 7 connected to the third line 6 facing downward. The second container 3 is placed below the first container 1 and is formed so as to be changed in shape by application of external force and to be restored by removal of the external force.

Abstract: A safeguard cap 1 is attached to an injection needle 10 that includes a hollow needle 11 and a holding member 12 for attaching the hollow needle 11 to a medical device. The safeguard cap 1 includes a housing part 2 for housing the hollow needle 11, a base 3 to be attached to the holding member 12, and a joint (bridges 4) for joining the housing part 2 and the base 3 to each other. The housing part 2 is formed in a tubular shape, with one end thereof being open and the other being closed. The joint is formed so as to be broken when external force for rotating the housing part 2 about its longitudinal axis that serves as a central axis is applied to the housing part 2, with the base 3 having been attached to the holding member 12.

Abstract: The configuration of the present invention includes a winged shield that has a cylindrical shield tube and wings linked to a front end side of the shield tube, a hub that is inserted into an inner bore of the shield tube so as to be movable in an axial direction, and a cannula that is mounted to a front end portion of the hub. By engaging a protrusion with a third annular groove, the hub is held with the winged shield in a state where the cannula protrudes for a predetermined length from a front end of the shield tube. In a state where an inward annular protrusion of the shield tube is engaged with a first holding portion, a tip of the cannula can be stored in the shield tube. By engaging the protrusion of a holding mechanism with a first annular groove, the hub is held with the shield tube so as not to be moved within the shield tube.
