Protector and method for using same

摘要

A protector includes an outer tube and an inner tube. The outer tube includes an outer tube main body including an outer tube lumen for housing a puncture device, a holding part for holding a hub, and a lumen inclined part extended from the holding part. The inner tube includes an inner tube main body and an extended part. The inner tube main body is held in a proximal end side of the outer tube lumen and is movable in a proximal end direction of the outer tube lumen. The inner tube main body includes an inner tube lumen into which a tube is inserted. By moving the inner tube in a distal end direction, the inner surface of the lumen inclined part is abutted against the extended part, and the extended part is biased by the lumen inclined part in a direction in which a diameter of the tube is reduced.

主权项

1. A protector configured to be used by being attached to a puncture device including a needle tube which includes a needle tip on a distal end side thereof, a hub provided to a proximal end side of the needle tube, and a tube connected to a proximal end side of the hub and communicating with the needle tube through the hub, the protector being movable in a longitudinal direction of the tube, the protector comprising:
an outer tube including:
a tubular outer tube main body which includes an outer tube lumen configured to house the puncture device;a holding part configured to hold the hub in the outer tube lumen to house the needle tip in the outer tube lumen;and
an inner tube including:
a tubular inner tube main body which is held in the proximal end side of the outer tube lumen and movable in a distal end direction of the outer tube lumen and includes an inner tube lumen into which the tube is inserted;said protector further comprising
at least one extended part coupled to said inner tube main body; and a lumen inclined part coupled to said outer tube, said lumen inclined part having an inner diameter that gradually increases towards said at least one extended part thereby forming an inner inclined surface, wherein, when the puncture device is housed in the outer tube lumen, the inner tube is moved in a distal end direction of the outer tube, whereby said inner surface of the lumen inclined part is abutted against the extended part and the extended part is biased by the lumen inclined part in a direction in which a diameter of the tube is reduced.
