A fluid transfer device may include a body member and a fluid transfer tip, wherein the fluid transfer tip may include a tapered friction fitting for a corresponding hub. The fluid transfer device also may include a disconnecting member having a front portion and a rear portion and engagement features operating between the disconnecting member and the body member. The engagement features engage with one another to inhibit the front portion of the disconnecting member from moving relative to the fluid transfer tip. The fluid transfer device is arranged such that upon application of a force to the rear portion of the disconnecting member, the disconnecting member deforms so that the engagement features are no longer in engagement with one another. This allows the front portion of the disconnecting member to move relative to the fluid transfer tip and subsequently release the hub from the friction fitting.

Disclosed are medical devices for use in delivering a medical solution into the body of a patient, including: an elongated main body defining a reservoir for containing a medical solution; longitudinal tip extending axially and distally from the main body, the longitudinal tip defining a fluid path extending axially through the longitudinal tip and in fluid communication with the reservoir; and a gripping portion formed on an outer surface of the longitudinal tip, wherein the main body and longitudinal tip are made of glass, the gripping portion including at least three ribs integrally formed with the longitudinal tip and extending around a longitudinal axis of the longitudinal tip, and the gripping portion has an average roughness of 0.5 m to 3 m.

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.

An apparatus includes a housing coupled to a medicament container, which is coupled to a needle. An injection assembly is disposed within the housing and includes an energy storage member and an actuation rod. A distal end portion of the actuation rod is disposed within the medicament container. The energy storage member can produce a force on a proximal end portion of the actuation rod sufficient to move the distal end portion of the actuation rod within the medicament container. This can convey at least a portion of a substance from the medicament container via the needle when a distal tip of the needle is disposed within a first region of a target location. The force is insufficient to move the distal end portion of the actuation rod within the medicament container when the distal tip of the needle is disposed within a second region of the target location.

The present disclosure provides medical devices, particularly medical grade needles with removable tips, as well as methods of needle tip installation and removal, and devices therefor. Needle tip installation and removal devices may include needle tip installation and removal tools and kits, including hand held and manipulated tools that facilitate the installation and removal of needle tips, particularly on vascular access port needles. Such installation and removal devices may provide more expedient hook up of the access port for the therapy. Also, the installation and removal of the needle tips may be conducted in a more sterile manner.

Improved apparatus for use with medication in fluid form, which is particularly beneficial for medications having a relatively high viscosity. The disclosed syringe adapter has an opening that is relatively large, as compared to a conventional needle, and thus affixing the disclosed syringe adapter to a syringe improves syringeability of higher-viscosity medications. When the disclosed syringe adapter is affixed to a pistol-grip or tab-handled syringe, the medication withdrawn into the pistol-grip syringe can be more easily administered from the syringe barrel. In some embodiments, the syringe adapter will be replaced with a needle prior to injecting the medication, while in some other embodiments, the needle is affixed to the in-place syringe adapter for the injection.

An apparatus for injecting a fluid includes: an injector including a cylindrical container, a coupling portion, and a peripheral section; a needle assembly including a needle and a hub defining a contact area, the coupling portion configured to be coupled with the hub; and a needle retention device including a needle-retainer portion having a finger configured to radially extend over at least a part of the contact area of the hub, a container-contact portion defining a first opening configured to be attached in a form-fitting way onto the peripheral section of the container. When the apparatus is in its operational state, the hub of the needle assembly is coupled to the coupling portion, the container-contact portion is attached to the container, and the finger of the needle-retainer portion extends over the contact area of the hub when the needle retention device is in its retaining position.
