  • Patent number: 8973622
    Abstract: Some embodiments disclosed herein related to a device for transferring precise amounts of fluid from at least one source container to a at least one target container. In some embodiments, the fluid is first transferred from the source container (e.g., a vial) through a connector to an intermediate measuring container (e.g., a syringe). In some embodiments air can pass through an air inlet and enter the vial to compensate for the volume of fluid withdrawn from the vial. An air check valve or a bag or a filter can prevent the fluid from escaping through the air inlet. The precisely measured amount of fluid can then be transferred from the intermediate measuring container to the target container (e.g., an IV bag). In some embodiments the connector can include a source check valve and a target check valve to direct fluid first from the source container to the intermediate measuring container and then from the intermediate measuring container to the target container.

  • Publication number: 20150051555
    Abstract: Some embodiments comprise a connector including a rigid housing having a first end and a second end. A second member can be positioned at a second end portion of the housing and be engageable with a second device. The second member can have a body portion having a first body portion, a second body portion, and a flow lumen extending axially through the body portion, an annular covering portion extending in a radial direction away from the body portion, a receiving portion extending away from the covering portion in an axial direction, and at least one protrusion extending radially away from an outside surface of the body portion. In some embodiments, the second member can be supported by the housing such that, in an assembled state, the first body portion is positioned within the housing and such that the annular covering portion and the second body portion are positioned outside the housing.

  • Publication number: 20140299221
    Abstract: Fluid transfer systems are disclosed that can be configured to transfer precise amounts of fluid from a source container to a target container. The fluid transfer system can have multiple fluid transfer stations for transferring fluids into multiple target containers or for combining different types of fluids into a single target container to form a mixture. The fluid transfer system can include a pump and a destination sensor, such as a weight sensor. The fluid transfer system can be configured to flush remaining fluid out of a connector to reduce waste, using air or a flushing fluid.

  • Publication number: 20130231616
    Abstract: A medical connector providing connection between medical devices comprising a female end connectable with a male end of a first medical device, a generally circular covering portion attached to the female end that is substantially wider than the transverse cross-section of the female end, a second end configured to connect with a second medical device, a housing extending between the female end and the second end comprising a region adjacent the covering portion that is wider than an outer diameter of the covering portion. In a first stage, the female end is configured to remain stationary with respect to the housing while the male end of the first medical device is rotated onto the female end. In a second stage, the female end is configured to rotate with respect to the housing to inhibit disconnection of the male end of the first medical device.

  • Patent number: 8246541
    Abstract: Microdialysis systems and methods that enable self-diagnostic functions for microdialysis, including continuous monitoring of diffusion, convection, and osmosis, as well as providing intelligent flow rate control, to mitigate variability in analyte recovery. The microdialysis system measures real-time tracer concentration levels in the dialysate and/or real time flow rates of the dialysate. A control circuit may compute the real-time tracer concentration levels in the dialysate and/or real-time flow rates of the dialysate based on real time tracer concentration data from an in-line tracer concentration meter and real-time flow rate data from an in-line flow rate meter. Analyte concentration data for the dialysate may also be measured using an analyte concentration meter. The control circuit may compute a corrected analyte concentration for the dialysate based on the analyte concentration data, the tracer concentration data, and the flow rate data in various embodiments.

  • Patent number: 8002765
    Abstract: A medical valve has a body and a flexible element. The body includes a wall structure defining an internal cavity having an inside and an outside. The body also has a proximal end and a distal end. The proximal end has an opening sufficiently large to receive a tip of a delivery end of a medical implement which transfers fluid through the delivery end. The body has a fluid escape space in its wall structure. The flexible element is adapted to be moved into a compressed state upon insertion of the tip of the medical implement into the opening. The flexible element is sufficiently resilient to return to a decompressed state upon removal of the tip of the medical implement from the opening. The fluid escape space is in fluid communication with the outside of the cavity when the seal is in its compressed state.

  • Patent number: 7998134
    Abstract: A luer connector including a rigid housing having a first end and a second end. The housing further including a rigid tubular male portion at the first end, a rigid tubular female portion at the second end, and a longitudinal opening therethrough. The male portion is configured to be engageable with a female connector. The female portion is configured to be engageable with a male connector and to prevent the disengagement of the male connector from the female portion. In some embodiments, the female portion is configured to maintain a fixed rotational position when the male connector is being threaded therewith, but to rotate with the male connector once the male connector has become fully engaged with the female portion so as to prevent the male connector from becoming unthreaded from the female portion.

  • Patent number: 7722575
    Abstract: A closed system, needleless valve device includes a generally tubular body defining an internal cavity. On the proximal end of the body there is an opening which is preferably sufficiently large to receive an ANSI standard tip of a medical implement. The distal end of the body has a generally tubular skirt. The valve also includes a hollow spike having a closed tip. The spike includes at least one longitudinal 18-gauge hole located distal the tip, and is seated inside the cavity such that the tip is below the proximal end of the body. An annular support cuff is connected to the spike which seals off a portion of the cavity of the body such that an upper cavity containing the tip is defined. The valve also includes a plastic, resilient silicone seal which fills the upper cavity and opening and covers the tip of the spike so as to present a flush surface. An adaptor enables the valve to be attached to a resealable container.
