    • The present invention relates to an apparatus for mixing cells and exogenous material for delivery of the exogenous material into cells using electroporation in a manner that preserves cell viability and integrity of the exogenous material. The exogenous material can be polynucleotides, peptides, proteins or other pharmaceutical molecules. It further provides a chamber that can be used to electroporate the contents of the chamber after mixing. In accordance with the invention, cell suspensions that may be contaminated with degrading enzymes are stored separately from water-based liquids that contain the exogenous material. Contact of the two water-based liquids (cell suspension and exogenous material) first occurs within the chamber. The chamber of the present invention has two or more inlet ports to allow separate entrance of water-based liquids. Two other ports are vent and exit ports. The inside of the chamber allows flow of all water-based liquids down the same side of the chamber and curved comers for redirecting flow direction and gently mixing water- based liquids. The chamber also includes electrodes as chamber walls for electroporation of chamber contents.
    • 本发明涉及一种用于混合细胞和外源材料的装置,用于以保持细胞存活力和外源性材料的完整性的方式使用电穿孔将外源材料递送到细胞中。 外源物质可以是多核苷酸,肽,蛋白质或其它药物分子。 它进一步提供一个室,可以用于混合后电化室的内容物。 根据本发明,可能被降解酶污染的细胞悬浮液与含有外源性物质的水基液体分离储存。 首先在室内发生两种水性液体(细胞悬浮液和外源性物质)的接触。 本发明的腔室具有两个或更多个入口端口,以允许单独进入水基液体。 另外两个端口是排气口和出口。 室内部允许所有水基液体在腔室的同一侧流动并弯曲,用于重新定向流动方向,并轻轻混合水基液体。 该室还包括电极作为用于室内容物电穿孔的室壁。

    • A needle guard (10) includes a clip (12) with a canting wall (16) to grip the needle shaft (56) and a distal wall (20) to block the tip (58) thereof, wherein the canting and distal walls may be interconnected by an angled strut (24), a spring member (14), such as a leaf spring, may have a portion extending past an edge (27) of the strut to bias the clip to grip the needle shaft, and the distal wall may be or include a stylus (38) and have an L-shape to define a lip (36) to help block the needle tip. The clip may have a depending heel (34) to help pivot the clip about a ledge (72) to grip the needle shaft. A needle support (80) may be provided to limit flexure of the needle which might otherwise allow the needle to come loose from the clip. Arrangements (300, 302) for limiting rotation of the needle hub and needle guard housing are provided, as is a protective shroud (320) to reduce the risk of inadvertent activation of the needle guard. Further, the needle guard may be used with a catheter assembly (200). Also provided is an improved duckbill release mechanism (260, 268).
    • 护针器(10)包括具有用于夹持针轴(56)的倾斜壁(16)的夹子(12)和用于阻挡其的尖端(58)的远端壁(20),其中倾斜壁和远端壁可以 通过成角度的支柱(24)相互连接,诸如片簧的弹簧构件(14)可以具有延伸超过支柱的边缘(27)的部分以偏压夹以夹持针轴,并且远端 壁可以是或包括触针(38)并且具有L形以限定唇部(36)以帮助阻挡针尖。 夹子可具有悬垂的脚跟(34)以帮助围绕凸缘(72)枢转夹子以夹持针轴。 可以设置针支撑件(80)以限制针的弯曲,否则可能会使针从夹子上松脱。 提供了用于限制针座和针头罩壳体的旋转的装置(300,302),如同保护罩(320)一样,以减少无意中启动针头罩的风险。 此外,护针器可以与导管组件(200)一起使用。 还提供了改进的鸭嘴形释放机构(260,268)。
