Patent ID: 8882716

Claim:
A kit comprising: a bodily invasive tube that is a venous catheter, and a detachable device for adding one or more channels to the bodily invasive tube which detachable device comprises a capillary tube assembly having a proximal end and a distal end and comprises: a thin walled capillary tube shaft disposed with a capillary lumen extending from an open proximal end to an open distal end, and a fluidic adapter at the proximal end in fluid connection the capillary tube lumen, wherein the capillary tube shaft is adapted for dismountable insertion into a fluid-carrying lumen of the bodily invasive tube that is the venous catheter, such that the distal tip of the capillary tube protrudes from the distal tip of the bodily invasive tube, and to maintains the flow function of the venous catheter, the adapter is configured to provide fluidic access to the capillary tube lumen that is fluidically isolated from access to the invasive tube lumen, and an applicator wherein the detachable device is packaged in the applicator, said applicator comprising: a longitudinal protective cover having a proximal end and a distal end, an opening at the distal end, wherein the protective cover forms a void in which the capillary tube shaft and at least a distal part of the adapter are disposed, and the cover is configured such that the capillary tube shaft is slidable relative to the opening at the distal end, wherein an intermediate coupling is dismountably attached through the opening at the open distal end of the applicator cover, which coupling has a proximal and distal end, a fluidic coupling at the proximal end of the intermediate coupling configured for attachment to the adapter of the capillary tube assembly and a fluidic coupling at the distal end of the intermediate coupling configured for attachment to a coupling on the invasive tube, both fluidic couplings of the intermediate coupling joined to an internal chamber, wherein at least a proximal part of the intermediate coupling is deposed in the void of the protective cover, and the distal end of the capillary tube shaft is positioned for passage through the fluidic coupling at the proximal end of the intermediate coupling.
