More than a million times every year, an ambulance is deployed in the Netherlands. Of these instances, 87% of the patients will be administered intravenous (IV) fluids. In the current situation, the IV bag always needs to be held above the patient to function properly. This action requires an extra pair of hands, which is very inefficient and can result in the loss of precious time that could otherwise be directed at the patient. Besides needing an extra pair of hands, there is also a chance of air bubbles entering the patient through the drip feed. The novel drip chamber design proposed in this paper aims to solve these problems, as it enables the IV bag to be placed in any orientation and in any manner relative to the patient with a negligible number of air bubbles entering the drip feed. This novel drip chamber was tested in an experimental setting in different orientations and at different flowrates. From the test results, it can be concluded that at a clinical relevant flowrate, a negligible number of air bubbles were present within the IV system. Because of the ease of use of the novel drip chamber and the fact that it is fool-proof, cost-efficient, and shows promising test results, future research on several aspects could make this product a promising addition to health care.
