  • Patent number: 10500390
    Abstract: A medical connector of the present invention is characterized in that: when a male connector portion is inserted into a female connector portion, a first locking portion is engaged with the female connector portion to achieve a first locked state as well as a second locked state; when the second locked state is released by operation of a second unlock operating portion and the female connector portion is moved in a disengagement direction with respect to the male connector portion, the locking member is moved in the disengagement direction together with the female connector portion while keeping the first locked state; and when the female connector portion is rotated with respect to the male connector portion, the first locked state is released.

  • Patent number: 9925364
    Abstract: The present invention relates to a catheter connector configured to provide an escape location for a liquid medium trapped therein. The catheter connector includes a body having a proximal end and a distal end. The proximal end includes a proximal end port for mating communication with a fluid delivery device. The body defines a hollow interior extending from the proximal end to the distal end. In one embodiment, the catheter connector includes an insert configured within the hollow interior of the connector. The insert defines a bore therethrough that is configured to receive a catheter at least partially therein. Further, the bore includes an interior wall and an exterior wall defining a thickness therebetween. The interior wall includes at least one discontinuity. Thus, when the catheter is inserted through the bore, at least one cavity is formed by the catheter and the at least one discontinuity of the insert.

  • Patent number: 9022969
    Abstract: A medical infusion fluid handling system, such as an automated peritoneal dialysis system, may be arranged to de-cap and connect one or more lines (such as solution lines) with one or more spikes or other connection ports on a fluid handling cassette. This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the one or more lines and the one or more spikes. For example, the automated peritoneal dialysis system may include a carriage arranged to receive the one or more lines each having a connector end and a cap. The carriage may move along a first direction so as to move the connector ends of the one or more lines along the first direction, and a cap stripper may be arranged to engage with the caps on the one or more lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.

  • Patent number: 8858493
    Abstract: A cap, especially a disinfectant cap, is for protecting and/or closing off the abdominal connector used in peritoneal dialysis, and to a detection device for peritoneal dialysis. There is a bag set for peritoneal dialysis and use thereof. In view of the sometimes serious consequences of an incorrect sequence of fluids in the patient's abdominal cavity, it is desirable to prevent an incorrect sequence of fluids during peritoneal dialysis. This is achieved by providing the cap, especially a disinfectant cap, with information about the medium contained at any one time in the patient's abdominal cavity. In this way it is always possible—even after the fluid has been dispensed into the abdominal cavity and the bag disposed of—to determine which medium is currently in the patient's abdominal cavity and/or to record other details, such as the amount, the concentration, the manufacturer, etc.

  • Publication number: 20140303601
    Abstract: Some embodiments relate to a luer connector comprising a housing having a hollow bore therethrough, a first end, and a second end, a male luer tip supported by the housing configured to rotate with respect to the housing, the luer tip having a first open end and a passageway through the luer tip in fluid communication with the first open end, and a substantially rigid internal member extending into the passageway of the luer tip toward the first open end of the luer tip. In some embodiments, at least one of the luer tip and the internal member can be axially moveable between a first closed position and a second open position relative to the other of the luer tip and the internal member. Further, the luer tip and the internal member can cooperate such that rotation of the luer tip in a first direction relative to the housing increases an axial displacement between the first open end of the luer tip and an end portion of the internal member.

  • Patent number: 8845586
    Abstract: A warming device for an IV fluid line according to the present invention includes a warmer unit and a wye type fitting with an injection site. The warmer unit includes a tube for intravenous fluid and channels containing a warming fluid to heat the IV tube. One fitting branch is connected to an intravenous fluid source, while the remaining branch houses the injection site. The injection site branch includes an injection safety member that ensures a syringe needle or other instrument is contained within the fitting to prevent rupture of the IV tube. The warming device may include an additional wye type fitting coupled to the initial fitting and including another injection site, where the fittings typically exclude the safety member. A syringe needle is inserted into the additional injection site to prevent rupture of the IV tube. In addition, the warming device may be configured for needleless injections.

  • Patent number: 8821459
    Abstract: A system and method for more efficient cleaning and sterilizing of surgical handpieces by using a removable valve assembly. The valve assembly is removable to provide access to a first suction passageway and a second suction passageway for cleaning purposes. The valve assembly has a protrusion that engages with a handpiece to secure the assembly to the handpiece. The protrusion of the valve assembly may also be retracted into the valve assembly to allow the valve assembly to disengage the handpiece thereby allowing the valve assembly to be removed from the handpiece. The first suction passageway may also be removable.

  • Patent number: 8814849
    Abstract: An intravascular valve assembly having a valve case and a flexible pressure-actuated flow control valve. The valve case includes attached proximal and distal case portions that present respective spaced apart fluid ports and a fluid passageway extending between the ports. The flexible pressure-actuated flow control valve is disposed within the fluid passageway and includes a slitted central valve wall. The proximal case portion includes an axially-extending boss that projects distally, with a portion of a distal end of the boss contacting the flow control valve. The valve permits fluid flowing in a distal direction to pass through the slit. Fluid flowing in a proximal direction, however, causes the valve to compresses against the boss and the slit to close, thus restricting fluid flow in a proximal direction.
