A double barreled injector assembly for performing multiple sequential vaccinations includes a pair of barrels, each of which is engaged by a first terminus thereof to a bar and extends from a lower face thereof. A respective agent can be positioned in each barrel. Each barrel has an orifice positioned in a second terminus thereof. A pair of actuators is engaged to an upper face of the bar. Each actuator is operationally engaged to a respective barrel and can be actuated by action of a hand of a user to dispense an associated agent through the orifice of the respective barrel into an animal. The injector assembly allows the user to perform multiple sequential vaccinations with two different vaccines and will be useful in vaccination of herds or flocks of livestock, such as poultry, cattle, and the like.

Provided is an insertion mechanism with increased reliability and reduced components. The insertion mechanism uses a single engagement and release clip compressed within a housing of the insertion mechanism to engage a needle hub and catheter hub. A button is provided to move the catheter hub and needle hub in a distal direction until the engagement and release clip reaches a firing window in the mechanism housing. The engagement and release clip expands in the release window to release the needle hub from the catheter hub, permitting a return spring to move the insertion needle proximally while leaving the catheter inserted, and also retains the catheter hub in the deployed position.

Syringes which are suitable for dispensing and injecting medical foams for sclerotherapy are described and claimed. The syringes of the invention comprise a syringe barrel having a nozzle and a bore to receive a syringe plunger; a syringe plunger defined by a front end and a rear end connected by a tubular walls and having an internal hollow duct between the front end and the rear end, and through which foam can flow; and an injectate chamber formed by insertion of the front end of the plunger into the barrel. The syringes comprise a flow-disruptor arranged to modify the flow of foam as it enters the injectate chamber. In certain embodiments the syringes comprise waste chambers which capture and retain poor quality foam. The syringes are particularly useful for dispensing foams made with little or no nitrogen content and are configured to reduce the risk of air contamination during dispensing the foam. Kits comprising the syringes together with a suitable source of foam and methods of dispensing foam form further aspects of the invention.

A valved needle assembly including a needle hub provided to a proximal end side of a hollow needle, and a valve member incorporated therein for blocking communication with the hollow needle. A protrusion protrudes from a distal end side toward a proximal end side inside the needle hub and the valve member blocks the proximal end side of the protrusion inside the needle hub. A central valve part of the valve member having a slit moves toward the protrusion such that the slit is opened and placed in communication by the protrusion. The central valve part includes a distal end tubular part and a proximal end tubular part extending from its outer circumferential portion toward the distal end side and the proximal end side respectively.

An apparatus for administering a cancer drug, comprising an optical emitter operatively arranged to emit a visible point of light onto a tissue surface to be treated, a robotic arm, operatively arrange to move a drug-delivery device, in sequence, to each of a plurality of predetermined positions within the tissue to be treated, a tactile sensor operatively arranged at the distal end of the drug-delivery device to determine vertical height movement of the robotic arm for contact of the tissue surface to be treated, a reservoir arranged to store the cancer drug, a needle, operatively arranged to be moved to each of the specific positions within the tissue, and to deliver the drug at those positions, and, a torch head for generating non-thermal plasma in proximity to an end of the needle and the area to be treated.

A computerized electro-mechanical drug delivery device configured to deliver at least one dose of two or more medicaments. The device comprises a control unit. An electro-mechanical drive unit is operably coupled to the control unit and a primary reservoir for a first medicament and a secondary reservoir for a fluid agent, e.g. a second medicament. An operator interface is in communication with the control unit. A single dispense assembly is configured for fluid communication with the primary and the secondary reservoir. Activation of the operator panel sets a first dose from the primary reservoir and based on the first dose and a therapeutic dose profile, the control unit is configured to determine a dose or range of the fluid agent. Alternatively, the control unit determines or calculates a dose or range of a third medicament. Further, a dispense interface for use with a drug delivery device is disclosed.

The invention relates to a safety assembly having—an attachment ring attached to the tip of the container and—a safety device covering at least the distal end of the needle, the safety device attached to the attachment ring. The attachment ring has an inner ring having an inner face provided with a snap feature, which engages a complementary snap feature on the tip of the container to prevent axial movement of the inner ring with respect to the container. The snap feature moves radially to engage the complementary snap feature on the tip of the container; and an outer ring is fixed on the inner ring, with a sleeve portion surrounding at least a portion of the inner ring to prevent radial movement of the snap feature once the snap feature has engaged the complementary snap feature on the tip of the container.

A primary container assembly includes a primary container defining a body having a proximal end defining an opening configured to receive a plunger, a distal end opposite the proximal end and defining an outlet, and a chamber extending from the proximal end to the distal end that is configured to receive a drug. The primary container assembly further comprises a tube extending from a first end that is integrally attached to the distal end of the primary container to a second end opposite the first end, where the tube defines a channel extending from the first end to the second end. The primary container assembly also includes a hollow needle configured to penetrate skin of a patient.
