Syringes

Constant monitoring and administration of nutrients and medicine is difficult, especially with the workload on medical staff. Technology delivers automated solutions, but in this highly regulated industry, adoption of new technology is slower in comparison to other markets. There are different designs of syringe pumps but generally there is a control system, sometimes called the ‘brain,’ controlling one or more channels. Each channel contains a pump and syringe. The ‘brain’ can control each syringe pump individually. This type of system can deliver small doses (microliters or even picoliters) of nutrients or medications. While each part of the pump is vital to patient care, the ‘brain’ needs data from sensors to offer more control and features. Fluid amounts are set by providers which include a maintenance dose, but can include bolus doses. Position sensors drive the accuracy of syringe pumps. Detecting motor position, flow rate, and empty syringes verify these set amounts are delivered as set by the provider. Sensors also drive patient safety by detecting bubbles (ultrasonic sensors) and blockages (force sensors) in medical pumps and tubing. These sensors must work with the pump, have quick response times, and integrate easily with the logic system. For example, our AD-101 ultrasonic sensors are non-invasive, provide response times in less than 2ms, and have a 3.3V TTL output logic level. Additionally, an LED on the device provides a visual indication for bubble detection. Pump data and pump integration is essential for automated documentation, and is incorporated into a patient’s intake and output. Accurate, reliable medical sensors drive cost-effective solutions and value added features. For years, our experience and effective supply chain delivered these demands and values on time within budget for the medical industry.
