Accessibility of History and Instrumentation Data from Infusion Pumps

In the medical arts, infusion pumps are commonly used to deliver liquids, such as nutrients and medicaments, into patients' bodies. Infusion pumps can be classified as large volume or small volume. Large volume pumps are typically used for medications and fluids, such as nutrients, that need to be delivered to patients in relatively large volumes compared to other medications and fluids, while small volume pumps can be used to infuse insulin or other medicines such as opiates. While small volume pumps can take different forms, syringe pumps are one of several types of pumps that can provide precision infusion of small amounts of fluid.

Generally, infusion pumps provide a wide range of flexibility in administering fluids to patients. Often, the rate at which a medicament is introduced into a patient's circulatory system can be variably programmed, the total volume to be administered can be pre-set, and the time for administering the medicament can be scheduled for automatic delivery at a certain periodicity. While the pre-programming of infusion rates, times, and amounts with infusion pumps commonly enables a wide variety of treatment protocols that would be impractical, expensive, or unreliable if performed manually, it also presents the challenge of safely controlling the introduction of fluids into a patient when medical personnel are not continuously present or not directly administering the fluids to the patients by way of, e.g., hand-held syringes.

Current standards for medical practice, therefore, typically require that infusion pumps maintain so-called "history logs" containing infusion "history data". A history log, as known to those familiar with infusion pumps in practicing the medical arts, is a record of the history data, and the history data typically includes the aforementioned parameters of infusion rates, times, and amounts, along with identification of the fluids that were actually delivered to the patient. Perhaps even more importantly, history data commonly includes interruptions to delivery, warnings issued to the user regarding an "out-of-limits" delivery, and general user interactions such as starting a delivery or adjusting a delivery parameter.

Existence of these data logging standards thus implies a requirement that the data be retrievable - or at least readily accessible - to a wide range of personnel including medical practitioners, health care facility administrators, and regulatory authorities.

But given global markets for infusion pumps, logged data might not be accessible in a particular local language. Also, current methods for access to logged data often require the use or procurement of software other than what the user may have, or even custom or "one off" software. Additionally, history logs are often only accessible for viewing on displays of the pumps themselves, or might at most be accessible on peripheral devices or syste...
