Key elements
Technical Overview
Sizes and Flow Rates
The MedFuser® Multi-Flow NRFit elastomeric infusion pumps deliver flexibility of patient care allowing clinicians to set and/or vary the infusion flow rate throughout the infusion using the MultiFlow rate adjustment module and removable key. This system maximises the flexibility and utility of the MedFuser® pumps across various patient populations, from paediatric to geriatric, medication infusion protocols and therapies including:
- Pain Treatment / Analgesia
- Antibiotic therapies, including Outpatient Parenteral Antimicrobial Therapies (OPAT)
- Thalassemia
- Cystic Fibrosis
Compatible with all key routes of fluid administration
including: Intravenous, Subcutaneous, Epidural, Wound Infusion and Intra-Arterial.
MedFuser® MultiFlow NRFit Advantages
- Therapy Flexibility
Freedom to adjust the infusion rates allowing the physician to customise the patient’s pain management protocol. - Controlled Access
Safe lock with removable key provides flow control only to selected individuals. - Responsive Pain Management
Amount of drug infusion can be adapted to changing patient needs. - Effective Pain Management
Helps to reduce hospital stay and improve recovery time. - Ergonomic Flow Control Module with Integrated Clip
Multi-Flow rate control module is ergonomically designed to comfortably fit in the hand and allow convenient, secure and confident operation. Additionally, each module is equipped with an integrated clip for convenient attachment to a pocket or sleeve.
Advancing patient safety
MedFuser® Multi-Flow NRFit pumps combine a number of elements together to provide safe and effective infusions: Robust, UV light-shielded outer housing to protect infusate, accurate fluid level indicator, two integrated particle filters and air-eliminating filters, kink-resistant tubing and advanced flow control capillary. All of our NRFit pumps are clearly identified in yellow to ensure that the right device is used for the right therapy and right patient, providing peace of mind and confidence.
NRFit® connectors designed to enhance patient safety
by reducing the risk of “wrong route” medication errors in administering regional anaesthesia.
Quick and accurate identification
MedFuser® pumps with NRFit connectors feature a distinctive yellow colour across the pump housing, labelling and patient line, including a yellow connector and yellow hydrophobic cap.
Compatible with WoundSoak® CWI
wound catheters to optimise post-operative pain management. WoundSoak® catheters for postoperative continuous infusion fit perfectly onto our MedFuser® MultiFlow NRFit portable elastomeric pump. Using the continuous wound infusion technique, anaesthetics and analgesics are infused through a multi-hole catheter directly into the surgical site for optimised postoperative pain relief.

Two Integrated air-eliminating and particle filters
Every MedFuser® MultiFlow NRFit infusion pump is equipped with two integrated air-eliminating and particle filters. Each of these filters feature the 1.2 μm hydrophilic and 0.2 μm hydrophobic membranes in a single housing to automatically stop particles and expel air from the infusion line. Filter construction materials contain no natural rubber, latex or latex derivatives, PVC, hydroxyvinyl chloride, DEHP, BPA or TSE/BSE.
Filling port with a pressure-activated valve
Convenient and safe filling port with an integrated one-way valve, ensuring a secure filling process. Composed of a sonically welded, DEHP-free thermoplastic body and a latex-free silicone diaphragm. Fully compliant with standard ISO 80369-7 and made from materials approved to USP Class IV standards.
Distal cap with a hydrophobic valve provided with all MedFuser® MultiFlow NRFit pumps
Enables safe and confident priming of the patient line without the risk of fluid spills or medication exposure. The 0.2 μm hydrophobic membrane automatically stops fluid once the patient line is fully primed.
Integrated hanger and clip
Enables quick and secure mounting and positioning of MedFuser® Multi-Flow NRFit pumps.
