  • Publication number: 20230414876
    Abstract: A spring-loadable fluid injection device for a needle-free syringe is provided and comprises a trigger positioned within the housing and actuated by depression of a push button or lever disposed opposite the dispensing end at an external actuation surface. The trigger has a trigger latch configured to release a trigger catch as heaving part of the spring-loaded piston of the device. The trigger catch is configured to urge the trigger latch in a direction transverse to the injection axis when the piston moves from the unloaded position to the loaded position. The compression spring is retained around the piston and retained within the housing by a piston head. The device further comprises a syringe adapter and a safety cap which prevents accidental triggering. An embodiment further includes a prefilled syringe adapter for aseptic filling of a needle-free syringe from a prefilled syringe.

  • Publication number: 20210007933
    Abstract: A syringe comprising a syringe barrel having a distal end, a distal tip, a proximal end, a barrel sidewall extending between the distal end to the proximal end and defining a chamber, the barrel sidewall having a barrel sidewall thickness t, the distal end of the syringe barrel including a distal wall is disclosed. The syringe includes a connector extending from the syringe barrel including a collar disposed coaxially around an elongate tip in fluid communication with the barrel to form a channel between the elongate tip and the collar, including an inside surface, an outside surface and a plurality of ribs extending radially outwardly from the outside surface and separated by spaces, each of the plurality of ribs having a height H and a width W, wherein there is a ratio of the height H to the barrel sidewall thickness tin a range of 0.75 and 1.

  • Patent number: 10821053
    Abstract: A syringe comprising a syringe barrel having a distal end, a distal tip, an open proximal end, a barrel sidewall extending between the distal end to the open proximal end and defining a chamber, the barrel sidewall having a barrel sidewall thickness t, the distal end of the syringe barrel including a distal wall is disclosed. The syringe includes a connector integrally formed with and extending distally from the syringe barrel at the distal wall, the connector including a collar disposed coaxially around an elongate tip in fluid communication with the barrel to form a channel between the elongate tip and the collar, the collar including an inside surface, an outside surface and a plurality of ribs extending radially outwardly from the outside surface and separated by spaces, each of the plurality of ribs having a height H and a width W, wherein there is a ratio of the height H to the barrel sidewall thickness tin a range of 0.75 and 1.
