    • An adjustable infusion catheter (600) includes a flexible tube (602) containing one or more axial lumens (120) that allows fluid to flow from the proximal end of the catheter (600) to the distal end. A syringe (608) or infusion pump (700) is the usual pressure source for fluid at the proximal end. A plurality of small-diameter holes (160) are provided in a fenestrated area (165) near the distal end of the tube (602) to disperse fluid throughout a targeted region (800) within the patient's body. The length of the fenestrated area (165) of the catheter body (100) is adjusted by a slidable sheath (200) which can be positioned along the length of the fenestrated area (165) so that its exposed length substantially matches the targeted region (800). The ends of the slidable sheath (200) include a seal portion (167) to prevent leakage around the ends of the sheath (200). Heat shrinkable plastic material can be used to form the sheath (200) and the end seals.
    • 可调节输注导管(600)包括容纳允许流体从导管(600)的近端流到远端的一个或多个轴向腔(120)的柔性管(602)。 注射器(608)或输液泵(700)是用于近端流体的通常压力源。 多个小直径孔(160)设置在靠近管(602)的远端的开窗区域(165)中,以将流体分散在患者体内的目标区域(800)内。 导管主体(100)的开窗区域(165)的长度通过可沿着开窗区域(165)的长度定位的可滑动护套(200)来调节,使得其暴露长度基本上与目标区域 800)。 可滑动护套(200)的端部包括密封部分(167),以防止围绕护套(200)的端部的泄漏。 热缩塑料可用于形成护套(200)和端部密封。

    • An infusion device capable of administering liquid medication at a continuous flow rate, and upon user demand delivers a controlled volume dosage of liquid medication at a higher dosage flow rate. The dosage reservoir (200) remains empty until the user actuates it by selectively and temporarily removing the pressure source, such as a spring (230). During actuation, fluid rapidly flows from the medication reservoir (100) to fill the dosage reservoir (200). After actuation, the pressure source (230) exerts a higher pressure on the dosage reservoir (200) than the medication reservoir pressure (100), which results in a temporary higher bolus flow rate. Thus, two distinct flow rates are achieved with one flow restrictor element (700).
    • 能够以连续流速施用液体药物并且根据用户需求的输液装置以更高的剂量流速输送受控体积的液体药物剂量。 剂量储存器(200)保持空,直到用户通过选择性地和临时地移除诸如弹簧(230)的压力源来致动它。 在致动期间,流体从药物储存器(100)快速流动以填充剂量储存器(200)。 在致动之后,压力源(230)比剂量储存器压力(100)施加更高的压力,其导致剂量储存器(200),这导致临时更高的推注流速。 因此,通过一个限流元件(700)实现两个不同的流速。
