Guidewire insertion aid

摘要

A guidewire insertion aid is is configured to feed out a guidewire inserted in a housing in order to insert said guidewire into the lumen of a piece of medical equipment. In some examples, the insertion aid comprises: a main body, a housing support part and a guidewire support part. A sliding contact part is disposed between the housing support part and the guidewire support part. The sliding contact part extends in the lengthwise direction of the main body and has a sliding contact surface for the guidewire. A feed-out member is provided on the main body and has a water-retentive water-retention member. The feed-out member is disposed with the water-retention member side thereof facing towards the sliding contact surface. The feed-out member can be displaced while the guidewire is held between said feed-out member and the sliding contact part.
