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.

Guidewire insertion aid

[Issue] To provide a guidewire insertion aid which is very easy to operate because a lubricated guidewire can be easily fed out.

The sliding contact partextends in the lengthwise direction of the main body and has a sliding contact surfacefor the guidewire. A feed-out memberis provided on the main bodyand has a water-retentive water-retention member. The feed-out memberis disposed with the water-retention memberside thereof facing towards the sliding contact surface. The feed-out membercan be displaced while the guidewireis held between said feed-out member and the sliding contact part

A triple lumen catheter comprises a transfusion lumen (), a blood feeding lumen () and a blood removing lumen (). The transfusion lumen () has a distal end and a leading end portion (A), the leading end portion progressively reducing in diameter to a proximal end. A transfusion port () is formed in the proximal end of the transfusion lumen. The blood feeding lumen () has a blood feeding port () in a region of the proximal end of the leading end portion, the blood feeding port opening at least partially in an axial direction of the leading end portion. The blood removing lumen () includes a pair of blood removing ports () provided in opposite side walls of the catheter, the blood removing lumen extending from a distal end at least to the blood removing ports.
