Description of a Novel Patch Pump for Insulin Delivery and Comparative Accuracy Evaluation
Open accessAbstract
A new insulin patch pump for continuous subcutaneous insulin infusion was developed. The pump is composed of reusable and disposable parts and operates with a stepping motor. This pump was compared to a patch pump and a durable pump regarding basal rate and bolus accuracy. Using a microgravimetric method, boluses of 0.2 U, 1 U and 7 U, and a basal rate of 1 U/h were tested. For all pumps, bolus accuracy was higher when larger volumes were delivered. While median deviations were similar for all pumps, there were differences in the precision of individual boluses and when regarding basal rate delivery divided into 1-h windows.

The prototype's delivery accuracy is similar or even better than that of all commercially available pumps tested in a comparable experimental setting.
“Our study results suggest that the tested pump prototype provides delivery accuracy and occlusion detection that is similar or even better compared to all commercially available pumps tested with a similar experimental approach.”
From Accuracy Evaluation of a Novel Reusable Patch Pump Prototype (2023) · cites this paper as [8]
Deviations from target for the prototype were similar or lower compared to other patch pumps currently available on the market tested in a similar experimental setting.
“However, the results of this investigation showed that deviations from target were similar or lower compared to other patch pumps currently available on the market and that have been tested in a similar experimental setting. 7,8”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
