摘要： A liquid dispensing nozzle assembly is provided for mounting on a liquid container and dispenser having a flexible wall and liquid storage cavity for manually squeezed dispensing of a liquid from the cavity through the nozzle assembly. The nozzle assembly maintains the liquid, such as contact lens saline solution, in sterile condition during storage and repeated dispensing of the liquid from the container cavity. The nozzle assembly includes a liquid conduit for communication from the container cavity to a liquid discharge port from the nozzle assembly to enable dispensing of the liquid displaced by manually squeezing the flexible wall of the container. The nozzle assembly also includes an air aspiration conduit separate from the liquid conduit for aspirating air into the container cavity to replace the dispensed liquid. The nozzle assembly includes a partitioned diaphragm including separate portions respectively included in the liquid conduit and the air aspiration conduit. The air conduit portion of the diaphragm can include a filter which is hydrophobic and air permeable but impermeable to bacteria to prevent entrainment of bacteria with the aspirating flow of air into the liquid storage cavity of the container.

摘要： A nozzle assembly is provided for a container and dispenser which maintains a supply of liquid, such as saline solution for contact lenses, in sterile condition during storage and has a flexible wall for manually squeezed displacement of the dispensed liquid from a storage cavity within the container. The nozzle assembly includes first and second conduits for defining separate fluid flow paths between an opening from the container and a nozzle from the structure. The first conduit enables flow of the stored liquid to be discharged from the nozzle orifice during squeezing of the flexible wall. The second conduit includes a barrier obstructing flow of the liquid through the second conduit which obstruction is permeable to air and impermeable to bacteria, allowing aspiration of air through the second conduit into the liquid storage cavity to replace the dispensed liquid and re-expand the container wall while preventing entry of any bacteria with the aspirated air.
摘要翻译： 为容器和分配器提供一个喷嘴组件，该容器和分配器在储存期间以无菌状态维持液体供应，例如用于隐形眼镜的盐溶液，并且具有柔性壁，用于将分配的液体从容器内的储存空间手动挤压移位 。 喷嘴组件包括第一和第二导管，用于在容器的开口和来自结构的喷嘴之间限定单独的流体流动路径。 第一导管能够在挤压柔性壁期间使储存的液体从喷嘴孔排出。 第二导管包括阻挡液体通过第二导管的阻挡物，该阻塞物可渗透空气并且对细菌不可渗透，允许空气通过第二导管吸入液体储存腔中以替换分配的液体并重新膨胀容器 同时防止吸入空气进入任何细菌。

摘要： A two-piece, single-use, disposable lancet assembly includes a housing containing a lancet formed from a spring wire integrally formed with a sharpened, skin-piercing probe end section. The spring lancet is mounted within the housing and is secured in a retracted, pre-tensioned or cocked position. A lever-like bar hingedly secured to the housing serves both as a closure for the access opening in the housing and as a lever for dislodging and for releasing the tensioned spring wire to actuate the skin-piercing probe to pulse functionally through a base port in the housing and then automatically to retract irretrievably into the housing.

摘要： An improved sterile docking apparatus for a medical-liquid, male connectors includes a holding member having an opening for matably receiving a nozzle end of a medical-liquid, male connector therethrough, and a film member disposed across the opening, wherein the film member is stretchable to envelope and thereby isolate a nozzle end of a medical-liquid, male connector that is inserted into the opening of the holding member. The film member may be elastic, wherein it substantially returns to an initial configuration after removal of a nozzle end of a medical-liquid, male connector from the opening of the holding member. An interconnection surface may be provided on the holding member of the docking apparatus to interface with a complimentary interconnection surface of a medical-liquid, male connector so as to maintain the nozzle end of the medical-liquid, male connector in an enveloped position during docking.

摘要： A sheath for receiving an ultrasonic probe and for defining the relative position of the probe with respect to a biopsy gun or a rigid needle is used for precise placement of the biopsy gun or needle tip in a structure. The sheath may comprise a keyhole-shaped slot for placement of a rigid needle through a puncture separate from a surgical port through which the sheath itself and the probe are introduced. A flexible catheter can thus be placed in a structure, using the ultrasonic probe to monitor its placement, followed by removal of the probe sheath and surgical port, leaving the catheter in place.
