Current insulin infusion sets are approved for only 2-3 days. The novel ConvaTec infusion set with Lantern technology is designed to extend infusion set wear time. The goal of this pilot study was to evaluate the duration of wear for this set. This was a pilot safety study in adults with type 1 diabetes using tethered insulin pumps. Participants inserted the set and wore it for 10 days or until failure. Among 24 participants, two were excluded. Forty-five per cent of the sets lasted 10 days. Median wear time was 9.1 (7.1, 10.0) days. Among 12 premature failures, six (50%) involved adhesive failures, four (33%) hyperglycaemia unresponsive to correction, one (8%) hyperglycaemia with ketones and one (8%) infection. Average CGM glucose per day of infusion set wear showed a statistically significant increase over time, while total daily insulin over the same period did not change. In this pilot study, the duration of wear for the novel infusion set exceeded previously reported commercial sets (P < .001). This extended wear technology may eventually allow for a combined glucose sensor and infusion set.
目前的胰岛素输注套件仅获得 2-3 天的批准。新型康维特输注套件 Lantern 技术旨在延长输注套件的使用时间。这项初步研究的目的是评估该套件的佩戴时间。这是一项在使用系绳胰岛素泵的 1 型糖尿病成人中进行的初步安全性研究。参与者插入该套件并佩戴 10 天或直至出现故障。在 24 名参与者中,有 2 名被排除在外。45%的套件佩戴了 10 天。中位佩戴时间为 9.1(7.1,10.0)天。在 12 例提前失效中,有 6 例(50%)涉及粘性失效,4 例(33%)为高血糖且对纠正措施无反应,1 例(8%)为高血糖伴酮症,1 例(8%)为感染。输注套件佩戴期间的平均 CGM 葡萄糖水平随着时间的推移呈现出统计学上的显著增加,而同期的总每日胰岛素用量并未改变。在这项初步研究中,新型输注套件的佩戴时间超过了之前报道的商业套件(P<0.001)。这种延长佩戴技术最终可能会实现葡萄糖传感器和输注套件的结合。
