Novel rapid infusion device for patients in emergency situationsKeywords: Rapid infusion system, fluid administration, trauma Abstract: We here describe a novel method to administer intravenous fluid rapidly and this method can be utilized in emergency and trauma settings.In prehospital trauma and emergency settings, the immediate establishment of venous access and rapid fluid administration may be difficult in resuscitation of patients in hypovolemic shock due to massive blood loss. Rapid infusion systems (RIS) have been successfully used for delivering large amount of intravenous fluids at standard and rapid flow rates. Although RIS are undoubtedly the convenient and most effective way of delivering fluids in short span of time but it has its own limitations.We present a novel device which can be successfully used in prehospital trauma and emergency settings. The steps for designing this equipment are as follows (Figure 1):1. A collapsible bag/Thin plastic intravenous fluid bottle is taken (A)2. The sterile Intrafix? safeset (M/S B. Braun Melsungen, Germany) is inserted in the intravenous (IV) fluid bottle and the other end is connected to the patient's intravenous cannula (B).3. The spike end of intravenous set is inserted above fluid level in fluid bottle(C)4. The sphygmomanometer inflation bulb is connected to latex end of intravenous tubing (that is inserted in fluid bottle) (D).5. The roller clamps of both IV tubing's are rolled ON.By inflating the inflation bulb of the sphygmomanometer the air is pushed in the fluid bottle. This creates a vertical pressure head on the surface of the fluid column and along with gravitational force, it pushes fluid through the fluid bottle along the IV tubing, to the patient. The Intrafix? safe set (M/S B. Braun Melsungen, Germany) IV infusion assembly is used for infusing fluids to the patient.In the past, there were many methods used for rapid delivery of fluids. Amongst them various pressurization techniques like gravity-fed infusion, manual compression of fluid chamber, and compression of fluid chamber using flexible (Infusable Disposable Pressure Infuser,
