  • Patent number: 10046154
    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.

    Abstract: An on-body injector and method of use including an on-body injector for use with an injection device. The on-body injector includes a bolus reservoir; a bolus injection needle in fluid communication with the bolus reservoir, the bolus injection needle having a bolus injection needle tip aligned with the injection port, the bolus injection needle being slideably biased away from the injection port to define a gap between the bolus injection needle tip and the injection port; and a button operably connected to the bolus injection needle to slide the bolus injection needle along the injection axis. The button is operable to advance the bolus injection needle tip to close the gap and advance the bolus injection needle tip into the injection port. The button is further operable to advance a plunger through the bolus reservoir to deliver a predetermined bolus volume to the patient through the injection flow path.

  • Patent number: 9017295
    Abstract: A syringe adapter with a ball-typed valve has a base, a dosing tube mounted around the base and a resilient valve mounted in the base and the dosing tube. The base has a guiding groove and an inner liquid channel communicating with each other, as well as an exhaust channel. Liquid medicine injected into the syringe adapter flows through the guiding groove and causes the inner liquid channel to be injected into a patient's body. The liquid medicine remaining in the split is cleaned when cleaning fluid is injected to clean the syringe adapter. Air in the syringe adapter flows out through the exhaust channel and is not injected into the patient's body, so the patient is free from pain. Furthermore, elements and assembling processes of the syringe adapter are simplified and manufacturing cost of the syringe adapter is lowered.
