A system for mixing drug products and injecting includes a syringe body, proximal and distal stopper members disposed in the syringe body, a plunger member, and a needle hub assembly coupled to the distal needle interface of the syringe body. The proximal and distal stopper members form a proximal drug chamber between there between and a distal drug chamber between the distal stopper member and a distal end of the syringe body. The plunger member includes a needle retention feature, an energy-storage member, and an energy-storage member latching member all disposed in disposed in a plunger interior. First and second sizes of the respective proximal and distal drug chambers can be modified by movement of the proximal and distal stopper members relative to the syringe body. The needle is at least partially retractable into plunger interior upon manipulation of the plunger member relative to the syringe body.

Apparatus and method are described employing pressurized gas to transfer, mix and/or reconstitute medicament contained in a vial and flowing it into an injection device. Pressurized gas may be provided by prefilled cartridge.

A self-admixing disposable hypodermic needle (admixing needle) includes a reservoir containing an additive, such as a buffering agent, to facilitate homogeneous mixing of the additive with an injection fluid, such as Lidocaine, contained in a cartridge held within a mechanically conjoined syringe. The admixing needle establishes a fluid communication pathway for hypodermically delivering the injection mixture to a patient preceding a potentially painful dental or medical procedure. Prior to removal, a delivery needle cap is pushed toward the syringe to dispense the additive into the cartridge. The delivery needle is then placed within the patient's tissues and the syringe is operated to force the injection mixture from the cartridge. Mixing surfaces on the male body (reservoir plunger) and the female body (reservoir) and other mechanical features homogeneously combine the injection fluid with the additive as the injection mixture travels through the admixing needle during the hypodermic injection.

Systems, devices and methods to establish fluid communication between vessels. Containers and devices having a unitary multiple entry port structure and a port unitary cover with buttons or levers for the assembly of customized final dosages of injectable beneficial substances. Containers and devices having a protective port with a cover configured to hermetically seal second container(s) within the protective port. A vessel having at least two entry ports and at least one exit port, and at least one container containing a dosing regimen, the at least one container configured to be received by one of the at least two entry ports of the vessel, whereby upon connection of the at least one container to the one of the at least two entry ports of the vessel, the dosing regimen in the at least one container is transferred into the vessel. Modular dosing system for adding at least one amount of a medicament to a preparation in a modular construction. System for displaying a dosing regimen or single amount of a medicament, so that the administrator of the amount is able to precisely ascertain the amount administered to a patient.

A syringe adapter includes a housing having a first end and a second end with the first end configured to be secured to a first container, a cannula having a first end and a second end with the second end positioned within the housing, and a collet having a first end and a second end with at least a portion of the collet received within the housing. The collet includes a body defining a passageway, a seal member received by the passageway, and an arcuate, resilient locking member connected to the body of the collet. The collet is movable from a first position where the locking member is open to receive a mating connector to a second position where radially outward movement of the locking member is restricted.

A multi-chamber drug delivery system includes vacuum chambers to provided vacuum-assisted mixing of first and second desired substances and/or injection of desired substances into a target tissue of a patient.

An assembly fixture device for attaching a vial adapter to a vial includes a base, a support member secured to the base, a handle connected to the support member, a vial adapter grip assembly connected to the handle and comprising an adapter grip member configured to engage and hold a vial adapter, and a vial grip assembly connected to the base comprising first and second grip members that are movable relative to each other and configured to engage and hold a vial. The first grip member is biased toward the second grip member to provide a vial engagement force, where the vial engagement force is about constant when a distance between the first and second grip members is less than 40 mm.

Systems for destroying or inhibiting cancer cells and other rapidly-dividing cells including an alternating polarity (AP) magnetic field generator and at least one AP electromagnetic coil adapted to be coupled to a target body area, and a controller to control the AP magnetic field generator and at least one AP electromagnetic coil and cause the field generator and coil to apply AP magnetic field having a frequency of 0.5-500 kHz and a field strength of 0.5-5 mT to the target body area to achieve a desired inhibiting effect on cancer cells or other rapidly-dividing cells. Treatments provided by the system may be co-administered with an anti-cancer drug such as a chemotherapy drug, a hormone therapy drug, targeted therapy drugs, immunotherapy drugs, or an angiogenesis inhibitor drug.

A syringe adapter includes a housing having a first end and a second end with the first end configured to be secured to a first container, a cannula having a first end and a second end with the second end positioned within the housing, and a collet having a first end and a second end with at least a portion of the collet received within the housing. The collet includes a body defining a passageway, a seal member received by the passageway, and an arcuate, resilient locking member connected to the body of the collet. The collet is movable from a first position where the locking member is open to receive a mating connector to a second position where radially outward movement of the locking member is restricted.

A system for injecting includes a syringe body defining a proximal opening and a distal needle interface. The system also includes a plunger member defining a plunger interior and configured to be manually manipulated to insert a stopper member relative to the syringe body. The plunger member includes a needle retention feature disposed in the plunger interior, an energy-storage member disposed in the plunger interior, and an energy-storage member latching member disposed in the plunger interior. The system further includes a needle hub assembly coupled to the distal needle interface of the syringe body. The needle assembly includes a needle having a needle proximal end feature, a hub, and a needle latching member configured to couple the needle to the hub. The needle is retractable into plunger interior upon manipulation of the plunger member to actuate the energy-storage member latching member.
