摘要:
A device (210) for the expression of liquids, such as for the maintenance treatment of vascular catheters. A syringe (216) has a support structure (215) and includes at least two separate compartments (211,212) in which liquids for treating the lumen (283) of a catheter (280) with which the device is associated. The syringe further includes a closure plug (213) to be associated with the lumen being treated, which is coupled, by virtue of a releasable securement arrangement, to support structure (215). At least one plunger (216) is also included for infusing, in preset order, the different treatment liquids into the lumen to be treated, and the syringe further includes a duct which is in fluid communication with the two compartments and is arranged through a through hole through the closure plug (213) in order to allow access of the treatment liquid to the interior of the lumen (283) upon activation of the plunger.
摘要:
A locking apparatus for connecting a catheter to a stem. The locking apparatus comprises a collet sleeve, which includes an annular wall defining a center channel and a plurality of resilient prongs protruding inwardly into a portion of the center channel. The locking apparatus also comprises a lockable insert, which includes an annular wall defining a center channel. The center channel of the lockable insert is coaxial with the center channel of the collet sleeve. The lockable insert is configured to be placed at a first locking position in which the annular wall of the lockable insert asserts no or minimal radial compression against the plurality of the resilient prongs of the collet sleeve, and the lockable insert is further configured to be moved to a second locking position in which the annular wall of the lockable insert radially compresses the plurality of the resilient prongs of the collet sleeve.
摘要:
A sheath assembly includes an elongated hollow sheath body having a proximal body end, a distal body end, and a longitudinal axis extending between the proximal body end and the distal body end. A sheath hub is fixedly connected to the proximal body end and includes a hub proximal end and a hub distal end with a through passage extending from the hub distal end to the hub proximal end and in communication with the hollow sheath body. The sheath hub further defining a valve seat proximate the hub proximal end. A valve is seated in the valve seat and includes a valve body with a bisecting slot extending into a proximal surface of the valve body and terminating at a depth less than the thickness of the valve body such that the remaining portion of the valve body distally of the slot defines a bridge extending between opposed halves of the valve body such that a distal surface of the valve body is substantially continuous, the valve extending across and sealing the through passage.

A Huber needle assembly includes a needle, a safety tube substantially around at least a portion of the needle, and a skin plate at one end of the safety tube. The safety tube is adapted to irretractably extend over the needle.
摘要:
A catheter (100) having a catheter body (102) having a proximal end (106) and a distal end (104) and a proximal portion fixedly connected to the proximal end. A magnet (120,220,320) is disposed around the catheter body (112) distally of the proximal portion and may be contained within a hub (208, 308).
