A self-sealing catheter valve that includes a flexible tubular part having a distal opening and an opposite proximal opening, and a proximal valve part. The proximal valve part has a curved self-sealing flexible diaphragm disposed inside the flexible tubular part and has a base perimeter united with a circumferential wall of the flexible tubular part. The curved self-sealing flexible diaphragm has a concave surface facing towards the proximal opening, and a convex surface facing towards the distal opening, and a flexible diaphragm wall of the curved self-sealing flexible diaphragm has a traverse slit. The self-sealing catheter valve provides an efficient self-closing mechanism for a peripheral catheter assembly and constitutes an efficient barrier against potential contagious spread from the patient to the surrounding environment by blood born disease e.g. HIV, hepatitis and Ebola viruses.

Self-sealing catheter valve

An inserter assembly for a peripheral catheter assembly configured with an adhesive plaster member, wherein the catheter tube extends through the plaster member. The inserter assembly includes a first inserter part having first and second legs, a bridge member connecting the first and second legs at a distance from each other, with the bridge member adapted for detachably engaging or holding at least a part of the needle module extending coaxially between the first and second legs. The inserter assembly includes a second inserter part for covering the needle. The plaster member impairs visual sight and the line of vision to the needle tip during puncture may be impaired. To prevent this the first inserter part serves for holding a back-folded part of the plaster member.

Inserter assembly for a peripheral catheter with a plaster member, method of configuring the inserter assembly with the peripheral catheter, and method of performing a blood vessel puncture

The invention relates to a method and arrangement for continuously measuring substances in a pressurised body fluid. A probe () for enabling continuous measurement of the concentration of one or more substances in a pressurized body fluid is provided. The probe is adapted to be inserted into the pressurized body fluid, and comprises an interface and an outlet lumen. Furthermore, the probe is configured so that a continuous and spontaneous fluid flow is established from the body fluid through the interface to the outlet lumen. The fluid flow from the outlet may be analyzed by a sensor.

Self-flowing measuring system

The invention relates to a microdialysis catheter comprising a multilumen tube () and a membrane (), said tube exhibiting at least two longitudinally arranged inner channels (), said channels extending from a proximal () end of the tube to the distal end () of the tube, whereat through-holes () are provided, one from each of said at least two channels to the outside of said tube, said channels () blocked for passage of liquid distally of the respective through-holes, a tubular membrane () arranged circumferentially around the tube () such as to cover the at least two through -holes (), said membrane is sealingly fastened () to the tube thereby forming a dialysis chamber () between the tube and the membrane.

Microdialysis catheter and a method of making a microdialysis catheter

A transcutan catheter assembly including a catheter having a distal end and a proximal end, and a collar of a relatively flexible material having an upper surface and a lower surface. The catheter extends in a fluid tight manner through the collar such that the distal end of the catheter protrudes underneath the lower surface of the collar and its proximal end is accessible at the upper surface for the connection of tubing to the catheter. The lower surface of the collar has adhesive properties for fluid tight attachment to the skin of a patient.

Transcutan catheter assembly

A microdialysis probe and catheter arrangement includes a catheter carrying in a distal end thereof a probe to be inserted in the body of a living being. The catheter has an elongate catheter body including a first channel for supplying a first fluid and a second channel for returning said first fluid. The first and second channels extend internally along the catheter body from a proximal end thereof to the probe. The probe includes a microdialysis membrane defining a dialysis chamber communicating with the first and second channels. A third channel extends internally along the catheter body and communicates with the second channel to supply a second fluid to thereto, thereby to increase the flow rate therein.

Microdialysis probe and catheter arrangement

A method of manufacturing a microdialysis catheter, comprises the steps of extruding a flexible material to form an elongate catheter body having a substantially cylindrical outer surface and a plurality of continuous internal channels extending in the longitudinal direction of said catheter body; sealing a free end of said catheter body; providing in said surface at a distance from said free end an opening extending into said catheter body to communicate with a portion of a first of said channels; providing communication between said first channel and a second of said channels at a distance from said free end shorter that said distance; and covering said opening by a microdialysis membrane.

Method of manufacturing a microdialysis catheter

A catheter for insertion into a blood vessel of a living being, which includes an elongated catheter body and membrane defining a dialysis chamber; a first channel provided for delivery of dialysis liquid to the dialysis chamber and a second channel provided for the discharge of dialysis liquid from the dialysis chamber, wherein the dialysis chamber comprises a plurality of tubular members, each having an inlet end and an outlet end, all the inlet ends being connected to the first channel and all the outlet ends being connected to the second channel.

Microdialysis catheter for insertion into a blood vessel

A catheter to be inserted into a blood vessel and guided by said blood vessel which comprises a substantially cylindrical wall structure which defines an elongated catheter body having a proximal end and a distal end, an opening formed in said cylindrical wall structure which extends into said catheter body forming a microdialysis chamber therein having a proximal and distal end, a microdialysis membrane covering said opening such that said microdialysis chamber has at least a portion of said microdialysis membrane as part of its wall, first and second channels extending through at least a portion of said catheter body and having proximal and distal ends, a cross channel connecting one of said first or second channels to the more distal side of said microdialysis chamber and the other of said first or second channels connected to the more proximal side of said microdialysis chamber, said proximal ends of said first and second channels being connected to an external means for circulating, monitoring and analyzing a microdialysis solution passing therethrough.
