Intravenous Therapy Products

The use of infusion therapy is almost routine in the Hospitals to-day. 90 percent of surgical patients and a third of non-surgical inpatients receive some form of intravenous therapy. Intravenous infusions are used for introducing fluids, nutrition, blood or its products, and medications to patients. Infusion product markets include vascular access and delivery devices. 

The question of safety has provided a major growth opportunity for equipment makers, and breathe some life into some of the mature segments of the IV business. The AIDS epidemic has given added urgency to design safer hardware. To this end, intravenous sets and catheters, have been amongst the newest innovations. 

The present quality standard by Bureau Of Indian Standards (BIS) no. IS – 12655 is in force and is required to be followed by the I.V. Set manufacturing firms with respect to the quality standards for I.V.Sets. 

However, the BIS has already revised the quality standard to match an International Standard, ISO 8536 – 4: 1988 (e). The new quality standard may be considered for implementation. 

While the BIS Standard gives the minimum quality standards required to be maintained by the manufacturing firms, it is generally the practice of various national and international brands to offer additional functional value to the users by adding specific quality features.

Infusion Systems For Anesthesia Care

Reliable and convenient intravenous infusion systems are among the most important aspects of anaesthesia care. Anaesthesiologists spend considerable time and effort staring IV infusion, regulating infusion rate, administering fluid boluses, monitoring infusion rate and making sure that the medications injected through the ports in the IV sets get reliably “flushed” into the patient’s circulation. With estimated 25 million surgeries per year, 50 million office base intravenous infusions, 40 million emergency room admissions and some 45 million hospital admissions, it is almost certain that the use of more flexible IV sets would result in an increased safety with their use and a reduction in labor-intensity related to their use and monitoring. Additionally, in addition to more comfort with their use, more flexible sets could also result in substantial cost savings by saving space and stocking costs through reduction in the need to stock several different IV sets. Additionally, their use would also eliminate the need to switch between sets (e.g., substituting MICRO for MACRO drips and vice versa), as well as eliminate the costs of wasted sets and the need to purchase costly speciality kits.

In summary, the gravity-driven IV infusion sets remain the most commonly used IV sets in anaesthesia practice. The survey clearly indicates that the present design of gravity IV infusion sets have inherent limitations and that anaesthesiologists combine various sets even in a single patient in order to meet their infusion needs. 

Administration Sets with in-line filters

Recent events in the UK have highlighted the fact that under some circumstances, users injecting drugs and additives into IV fluid bags sometimes scrape the needle along the plastic tube, resulting in strips of plastic (frequently spirals of plastic) peeling off the walls and ending up in the IV fluid. St Mary’s Pharmaceutical Unit (Penarth, South Wales) have stated that they believe that the 200 µ filters in blood sets will contain the particles in question.

This problem can usually be avoided by ensuring that the needle penetrates the injection port at 90° and not at an angle. 

The I.V. sets therefore are required to incorporate a filter. If the set is a solution set, the filter must be a 40µ filter or smaller, and for blood sets, the filters may be of any size, provided they filter blood to the same extent as a reference 200µ filter. 

The I V Sets designed for the delivery of, Blood, Solution or Drugs are of various types and have various features. The different Types include: 

Light Sinsitive , Low Adsorption, Burette, Continu-Flo, Secondary, Piggy Back with , Continu-Flo Plus , Paclitaxel Set, Epidural Analgesia , Syringe Adopter Set , PVC Free , Blood Set with pump Chamber , Venous Pressure Set, 0.22 Micron Bacteriological Filter, Air Eliminating Filter, Extension Set, Y-Type , Venting Air Inlet, Paediatric etc.
