摘要： Featured is a vascular access device such as an IV catheter device including a housing, a tubular member, a seal member, a compression member, and a securing mechanism. The housing includes a proximal and distal portion and a chamber that extends between the proximal and distal housings. The tubular member is coupled to the housing distal portion so it is fluidly coupled to the chamber. The seal member is disposed within the chamber and the securing mechanism secures the seal member distal end to the housing proximal portion so the seal member is sealingly and compressibly retained between a chamber proximal end and the securing mechanism. Such a seal member also forms a septum, which is compressed by the compression member to prevent seepage upon removal of a stylet.

摘要： A relatively flexible, dual-lumen enteral feeding tube for delivery of fluid through a patient's esophagus to the patient's digestive system, the enteral feeding tube having proximal and distal ends. The tube comprises an enteral feeding lumen having a feeding lumen inlet opening adjacent the proximal end of the tube and a feeding lumen outlet opening adjacent the distal end of the tube. Additionally, a relatively small stylet lumen is provided separate from said enteral feeding lumen, the stylet lumen having a stylet lumen inlet opening adjacent the proximal end of the tube and being longitudinally co-extensive with a substantial length of the enteral feeding lumen. A relatively stiff stylet having a tapered annealed distal portion is removably positioned in the stylet lumen and extends from the stylet inlet lumen opening to adjacent to the feeding lumen outlet opening. A Y-site adaptor is fixed on the proximal end of the tube and the stylet is shorter in length than the distance from either of the Y-site openings to the tube outlet opening. To facilitate insertion or removal of the stylet, which is constructed of metal, into or from the stylet lumen, a portion of the stylet is provided with a first coating of polytetrafluorethylene having a second coating of silicone over the first coating.
摘要翻译： 一种用于将流体通过患者食管输送到患者消化系统的相对灵活的双腔肠内喂养管，肠管具有近端和远端。 该管包括肠进食腔，其具有邻近管的近端的进料腔入口和邻近管的远端的给药腔出口。 此外，与所述肠内喂养内腔分开提供相对较小的探针管腔，探针管腔具有邻近管的近端的探针管腔入口，并且与肠进食腔的大部分纵向共同延伸。 具有锥形退火远端部分的相对较硬的探针可拆卸地定位在探针管腔中，并且从探针入口腔开口延伸到邻近进给管腔出口开口。 Y型接头适配器固定在管的近端上，探针的长度比从Y位置开口到管出口开口的距离短。 为了便于将由金属构成的探针插入或从探针管内取出，探针的一部分设置有在第一涂层上具有第二硅氧烷涂层的聚四氟乙烯的第一涂层。

摘要： Featured is a medical infusion device for vascular access with enhanced flashback visualization that includes a hub assembly having a flashback chamber. The hub assembly includes a proximal portion, a distal portion and a substantially transparent window section intermediate the proximal portion and distal portion. A needle is coupled to the flashback chamber so that fluid flows through the lumen of the needle into the flashback chamber after the needle is inserted into a blood vessel. A contrasting member is disposed on at least a portion of the hub assembly, so that when blood enters the flashback chamber, the contrasting member provides a high-contrast background when viewed through the window section.

摘要： The present invention relates to a sensed member and sensing member for use on a medical fluid infusion device and support device wherein the fluid infusion device is usable in a conventional manner such as on an IV pole and in an ambulatory manner such as in a support device for use in an ambulatory backpack. The sensing member of the present invention detects when the fluid infusion device is to be used in an ambulatory manner to adjust the operation of the infusion control member to account for the difference in fluid flow rates caused by the different fluid pressures within the fluid delivery set when the fluid infusion device is used in a conventional manner and an ambulatory manner.

摘要： A fill spout for a drainage device is disclosed which permits the user to supply water directly to a water seal chamber of the drainage device for establishing a water seal therein. The fill spout comprises a funnel having lateral sides for facilitating the entry of the water into the drainage device, a depending lip extending from the fill spout for preventing any run off or spillage, and a tab having an arcuate-shaped rest which permits the user to open and close the fill spout. In use, the user pulls the tab which opens the fill spout and places a water-filled bottle against the rest. The user then pours a predetermined amount of water through the funnel and directly into the water seal chamber.
