  • An intravenous or IV warming unit warms fluids provided to individuals by using an IV. Earlier units ran on AC power, were physicaly larger, and less efficient. They could not be effectively transported together with patients to other facility areas or applied to catastrophe response scenarios. Today technology has been utilized for boosting the efficiency of these vital treatment resources. Mobile devices can be powered via battery power. Their style and design is very light-weight. They include capabilities for intravenous application in addition to irrigation heating. A great number of facilities begin using these devices to scale back the possibilities of fluid-induced hypothermia. Warmers can use dry heat, water, or heat exchange technology in order to increase fluid temperature just before it enters the IV. Heat exchange products are the very best of the 3 methods. For the reason that microprocessors and additional technology have been employed in their style and design to increase efficiency.

    Mechanized Aspects Which Enhance the IV WarmerHas advanced the understanding of the warming device technology

    One particular technology is known as smart disposable. Typical warmers contain a distinct piece of equipment for the disposal path. A cassette or specific tubing is needed for disposal. Improved models all have the regular features necessary for a clean and sterile fluid path. Enhanced technology however, takes away the requirement for earlier disposal materials. A microprocessor inside the IV warmer handles fluid path warming. An intrinsic heater control board is merged with a heat exchanger. These types of mechanized items are covered by flame resistant plastic material. Stainless steel is commonly used for the tubing. The coil shaped stainless-steel accocunts for the fluid path for the heat exchanger. A flex circuit will then be welded to the fluid path. Standard fittings are applied for enhanced compatibility concerning IV administration and extension sets. The fluid stream itself includes two sensors that obtain an exact temperature measure. This allows for better heat control. An innovative IV warmer promises fewer setup mistakes. Professionals might have more confidence in the outcome of every single patient application. Former designs experience overheating. This really is because of overcompensation for reduced thermal conductivity supplied by commonly used medical device plastics. Stainless steel has higher heat conductivity. It decreases warming time and can react more rapidly to flow fluctuations. Overheating is not an issue with well designed equipment.

    Low mass heaters are another innovation. Previous products use hot warming plates or perhaps a large amount of hot water as the heating mass. When the fluid flow stops, remaining heat continues to be transferred to the infusate. This leads to temperature spikes. Low mass heaters do not supply heat in the event of an end flow condition. The power is kept in a very small mass that makes it insignificant. Sources of stored heat are avoided with this type of design. Fluid paths are regulated by temperature. The microprocessor circuit controls fluid path temperatures. A failsafe circuit is also located on the control board. It is attached to the flex circuit welded on the fluid path. The processor checks the fluid temperature employing the installed sensors. It then handles the heating power for consistency of temperature. This process is continual up until the IV warming device is no longer necessary. Previous heating methods do not have these precautions in place. They are prone to be less safe and unreliable.
