AI Technical Summary
Technical Problem
Existing subcutaneous ports suffer from problems such as infection, device mispositioning, chronic inflammation, and subcutaneous extravasation caused by rigid housings, necessitating the design of an implantable device that reduces fluid leakage.
Method used
The tubes and closure components, made of flexible resealable diaphragms and elastomeric materials, control fluid flow through compression, avoiding the use of metal or rigid plastic shells.
Benefits of technology
It enables flexible control of fluid flow, reduces fluid leakage, provides greater comfort and safety, and avoids the complications associated with traditional rigid shells.

Abstract
一种医疗设备包括管和闭塞构件。管由弹性体材料形成，弹性体材料足够刚硬以维持至少一部分腔并且足够柔性以限定沿着管轴线的可调节曲率。闭塞构件固定地设置在管腔内并且由通过管维持在压缩状态的弹性体材料形成。闭塞构件包括内部通道，内部通道具有由压缩力维持的关闭状态，防止流体流过内部通道，以及打开状态，其中流体的压力克服压缩力以至少部分地打开内部通道从而允许流体流过内部通道。
