Such tubing offers a design solution for medical systems which require the use of inert material solutions for drug delivery applications or bondable outer tubing layers.
Multi-layer tubing offers a modern, effective and practical solution for various medical applications. Such tubing offer a design solution for medical systems which require the use of inert material solutions for drug delivery applications or bondable outer tubing layers.
RAUMEDIC has developed processing capabilities to co-extrude a wide variety of metal wires and glass fibers within the tubing walls. The company can co-extrude and work with copper, stainless steel, Nitinol, platinum alloys, nickel and silver plated wires in combination with a wide variety of polymers, including Polypropylene, Polyethylene, Nylon, Polyurethane and Silicone, as well as high performance resins (FEP, PEEK, PPSU, PEI and PTFE Moldflon).
Within the medical device industry, many products need wires, cables and coils to be hand strung though multilumen tubing which can be labor intensive. With the RAUMEDIC approach of co-extruding wires within the tubing walls, fabrication costs can be significantly reduced. RAUMEDIC can offer co-extruded tubing where the wires are embedded or loose which can help with regards to kink resistance. A wide variety of wire and polymer combinations depending on the requirement can be adapted to the application requirement.
RAUMEDIC Tubing from PTFE Moldflon
RAUMEDIC produces tubing extruded from PTFE Moldflon. This is a special type of thermoplastic material that in contrast to regular PTFE can be processed from the melt, which is a major advantage in terms of economy and processability for PTFE. This is highly advantageous for long continuous tubing production runs, and it allows for PTFE with co-extruded radiopaque stripes and for secondary operations, such as tipping and flaring, without commonly known side effects such as flaking and cracking.
Silicone intelligence inside
Liquid Injection Molding pump segments are commonly used in enteral nutrition or pain management applications. High dosage accuracy represents an important criterion for today´s medical devices, hence pump segments made out of silicone must fulfill tightest tolerances. “Silicone Intelligence Inside – made by RAUMEDIC” integrates several functions or design requirements such as connectors and fixing elements as well as pressure sensors and bubble detection areas in one single part, avoiding costly secondary operations. A combination of silicone and thermoplastic parts in one system is also possible.
Set assemblies – Application example: Colpotransilluminator with vacuum hose
The example of the Colpotransilluminator with a vacuum hose, which is used in a gynecological application, clearly illustrates the various RAUMEDIC processing techniques. The tubing set consists of various components that are produced in multiple production steps.
The first step is the extrusion of the tubing. In a second step tubing is cut-to-length and assembled to various connectors. A 100% bond-strength test is performed to ensure that tubing and connectors are correctly linked together. All components are produced in-house whereby manual and customized-tool supported processing techniques such as extrusion, molding, cutting and assembly (bonding) come into play.
An easy fit connection of the Colpotransilluminator to the standardized suction port allows for ease of handling and use in the OR. With help of a minimally-invasive procedure, the tubing set ensures a hygienic and residue-free suction of the wound secretion which is important for an optimal healing process.
