Summary
Insulin pump accuracy varies significantly, impacting diabetes management. The Animas OneTouch Ping showed superior single and averaged dose accuracy compared to other models tested.
Area of Science:
- Biomedical Engineering
- Medical Device Technology
- Diabetes Technology
Background:
- Insulin pumps are crucial for diabetes management.
- Compliance with EN 60601-2-24:1998 may lead to assumptions of equal insulin delivery accuracy among manufacturers.
- This study evaluates dose accuracy across different insulin pump models.
Purpose of the Study:
- To investigate and compare the single-dose and averaged-dose accuracy of incremental basal insulin deliveries.
- To assess the accuracy of one patch-model and three durable-model insulin pumps.
Main Methods:
- A microgravimetric system with time-stamping was used to measure discrete single doses.
- Basal rate infusion of 0.5 U/h over 20 hours was simulated for each pump model.
- Dose accuracy was analyzed by comparing measured doses against accuracy thresholds (±5% to ±30%).
Main Results:
- Significant variations in single-dose accuracy were observed, with the Insulet OmniPod showing the highest percentage of inaccurate doses (79.1% outside ±5%).
- Averaged-dose accuracy improved over time, but the OmniPod consistently exhibited higher percentages of doses outside the ±15% threshold compared to other models.
- The Animas OneTouch Ping demonstrated the best overall accuracy for both single and averaged doses.
Conclusions:
- There are notable differences in insulin delivery accuracy among insulin pumps, particularly between patch and durable models.
- The Animas OneTouch Ping exhibited superior performance in both single-dose and averaged-dose accuracy.
- Further investigation into the clinical implications of these accuracy differences is recommended.

01:16Insulin: Dosing Regimen and Adverse Effects
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

01:24Drug Accumulation During Multiple Dosing: Intermittent IV Infusions
Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...
01:25Determination of Multiple Dosing Parameters: Loading and Maintenance Doses
A loading dose is an essential pharmacological strategy to rapidly achieve the target plasma drug concentration necessary for an immediate therapeutic effect. This approach is especially critical for drugs characterized by slow absorption or extended half-lives, where delaying therapeutic plasma levels could compromise treatment outcomes. By administering a loading dose, clinicians ensure a prompt onset of drug action, even for agents with complex pharmacokinetic profiles.Achieving steady-state...
01:01Dosage Regimen: Fixed Dose
Fixed-dose regimens are a common approach to administer drugs to achieve and maintain desired levels of the drug in the body. In this dosing strategy, a specific amount of medication is given at regular intervals, often multiple times a day, to ensure a consistent drug concentration in the bloodstream.
Fixed-dose regimens can be used for various routes of administration, including intravenous (IV) injections and oral medications. For IV administration, a predetermined amount of the drug is...

01:29Drug Dosing: Infants and Children
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
01:15Determination of Multiple Dosing Parameters: Steady-State, Minimum and Maximum Concentrations
Gentamicin, an aminoglycoside antibiotic, is commonly administered via intermittent intravenous infusion to treat severe infections. An intermittent one-hour infusion of gentamicin, administered at eight-hour intervals, allows for precise control of plasma drug concentrations, minimizing toxicity while ensuring therapeutic efficacy. Pharmacokinetic principles govern the dynamics of plasma concentrations and can be mathematically described using specific equations.The plasma drug concentration...
