Abstract: A needle shield having a front end opening through which a winged needle as a whole is retracted and a base end opening through which a flexible tube connected to the winged needle is passable. The needle shield includes a winged needle retention means projecting into the interior side of the needle shield to define one or more traps, the winged needle retention means receiving, into the one or more traps, portions of one or more wings of the winged needle for preventing protrusion of the winged needle past the winged needle retention means when the winged needle is translated within said needle shield towards the front end opening of the needle shield from a retracted state of the winged needle.

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: A telescopic intravenous infusion set and/or blood collection assembly is provided with a safety feature for covering the used needle. The safety feature is a telescopic device including a shield with handling wings, which when placed in cooperating relationship, allows accommodation of a conventional unmodified blood collection needle affixed to a hub, and a sleeve with a locking cap. After use, the hub with the needle are pulled rearwardly into positive locking position which prevent the hub and needle from moving out of the shield thereafter. The telescopic nature of the device then allows the locked needle/hub to move rearward in relation to the shield until the shield is unreleasably locked to the sleeve. The shield provides for passage of the needle and hub from a releasable locked use position to a shielded and unreleasable locked protected position.

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.
