Abstract
Description
前部および後部チャンバ62,64間の空気流を許容することに加え、通気溝70は、隔壁起動部材80によりスリット56を起動または開動する前に、カテーテルアダプタ14を通じて流体が流れるのを許容するよう、形成されても良い。幾つかの実施形態において、前部および後部チャンバ62,64間を流れる空気および/または流体の流量は、より増加または減少された数の通気溝70を含むカテーテルアダプタ14を生産することによって、調節される。他の実施形態において、前部および後部チャンバ62,64間を流れる空気および/または流体の流量は、より増加または減少された断面積の通気溝70を含むカテーテルアダプタ14を生産することによって、調節される。結局、幾つかの実施形態において、前部および後部チャンバ62,64間を流れる空気および/または流体の流量は、より増加された数の通気溝70、またはより増加された断面積の通気溝70を含むカテーテルアダプタ14を生産することによって、増加される。逆に、他の実施形態において、前部および後部チャンバ62,64間を流れる空気および/または流体の流量は、より減少された数の通気溝70、またはより減少された断面積の通気溝70を含むカテーテルアダプタ14を生産することによって、減少される。
