Abstract
A skin surface indwelling device for guiding punctures includes: an indwelling tube () having an inside tunnel (P) substantially extending along the longitudinal direction of the indwelling tube (), the tunnel (P) is used for guiding needle (N), the indwelling tube () has a proximal end positioned above the skin surface (S) and a distal end positioned under the skin surface (S) in indwelling state; a support () having a bottom surface on its bottom that directly or indirectly contacts with the skin surface (S), the support () supports and fixates the indwelling tube (); and a sealing elements () configured to seal the tunnel (P). The skin surface indwelling device for guiding punctures can shorten the time of establishing a puncture tunnel in the buttonhole puncture method, and help to build the puncture tunnel. In addition, the skin surface indwelling device can also guide the puncture needle (N) when puncturing, and protect the immature puncture tunnel.
