  • Patent number: 10973990
    Abstract: The processes for inserting fluid under the skin of a patient using a safety syringe assembly include initially locating an up-alignment marker. The marker is aligned with a bevel in the needle of the safety syringe assembly so the orientation of the needle bevel is always known by the medical professional, even when the needle bevel cannot be seen. The needle is inserted bevel up prior to insertion. Once inserted, the medical professional inverts the safety syringe assembly so that the bevel is down. This is done by merely flicking the wrist of the hand holding the safety syringe assembly. This prevents splash back of any body fluids from the patient to the medical professional. The same safety syringe assembly and the same process are used for withdrawing fluids from the body of the patient.

  • Patent number: 10960141
    Abstract: A method and apparatus are provided for use in locating a target region which is situated in the body of a subject, for example for the delivery of drugs. The system includes an assembly for controlling the flow of fluid from a fluid reservoir to a conduit, such as a needle. A sensor detects a characteristic indicative of the fluid pressure in the conduit. The system processes data from the sensor to detect the presence of a pulsatile waveform. A controller may control further operation of the system based on information regarding the presence of the pulsatile waveform and features of the waveform, such as amplitude.

  • Patent number: 10912898
    Abstract: A tamper evident closure assembly for a fitting including, but not limited to, use in combination with a female fixture or an enteral fixture. A cap is connectable in flow restricting relation to the fitting and includes an indicator member removably connected to an exterior thereof. A housing is dimensioned to removably contain the cap and the connected indicator member. Subsequent to the fixture being connected to the cap, a removal thereof results in the indicator member being detached from the cap and movably disposed in a captured, detached orientation within the housing. Tampering may be evidenced by the indicator member remaining captivated within the housing which may be determined by visual observation or the generation of sound caused resulting from the housing being shaken. An included drive assembly is structured for concurrent rotation of the housing and the indicator member one direction and relative movement there between upon rotation of at least a housing in an opposite direction.
