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.

Syringe with connector

Described is a medical adapter assembly comprising an end including a neuraxial fitting that is not directly connectable to a standard luer fitting, an opposing end including a fitting connectable to an intravenous medical device, and a check valve that allows fluid flow from the end with the standard luer fitting to the end with the neuraxial fitting, but prevents fluid flow from the end with the neuraxial fitting to the end with the standard luer fitting. Methods of using the medical adapter assembly and kits containing the medical adapter assembly are also described.

Neuraxial connector

Described is a medical adapter assembly comprising an end including a neuraxial fitting that is not directly connectable to a standard luer fitting, an opposing end including a standard luer fitting connectable to a standard luer fitting of an intravenous medical device, and a check valve that allows fluid flow from the end with the standard luer fitting to the end with the neuraxial fitting, but prevents fluid flow from the end with the neuraxial fitting to the end with the standard luer fitting. Methods of using the medical adapter assembly and kits containing the medical adapter assembly are also described.

Enteral syringe

Connectors for medical devices include visual and tactile features as an indicator of a connection-type of the connector. This allows for differentiation by type of connection under busy and/or low light conditions.

Medical devices with visual and tactile indicators

A syringe having barrel and a non-luer tip that is not connectable to an intravenous device is disclosed. The syringe as an enteral collar engagement feature adjacent the distal end of the syringe barrel. The syringe has an enteral collar having a distal end and proximal end, the proximal end having a syringe engagement feature complementary to and engagable with the enteral collar engagement feature. The enteral collar is sized to permit connection to an enteral device and prevent connection to a device having a luer connector

Syringe with enteral connection feature

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.
