A61M5/002
Medical fluid transfer and injection apparatus and method
Drug delivery system, injection device, transfer apparatus, vial holder and method of administering and transferring are disclosed which provide for passive warming of chilled injectable transferred through the transfer apparatus and into the injection device. The injection device may include a skin-facing surface including a skin boundary displacement extension or structure around a needle injection site to create a high pressure zone in the tissue. Radio frequency tracking and monitoring features for tracking patient compliance also may be provided.
METHODS FOR MANUFACTURING NON-GLASS PREFILLED SYRINGES
A method of sterilizing a prefilled syringe comprises assembling a syringe assembly and performing at least one ethylene oxide (EtO) sterilization procedure cycle. The assembling step includes inserting a tip cap at a first end of a plunger, filling a non-glass barrel with sterilization sensitive material at a second end of the barrel, and inserting the plunger into the barrel at a second end to seal the sterilization sensitive material within the barrel. The EtO sterilization procedure cycle comprises undergoing a preprocessing stage, a wash and conditioning stage, an EtO sterilization stage and a wash and post exposure stage. Upon completing the EtO sterilization procedure cycle, a resultant pH of the sterilization-sensitive material does not exceed an acceptable pH range as defined by the United States Pharmacopeia. The disclosure also discusses inserting an assembled prefilled syringe into a procedure tray prior to performing the EtO sterilization procedure cycle.
Apparatus for mounting a pen needle assembly
A storage device (30) for storing a pen needle assembly (10) includes a housing (30) having first wells (44) with a dimension for receiving the pen needle assembly and second wells (46) for receiving an inner shield (24) of the pen needle assembly. The second wells (46) have a diameter less than a diameter of the first wells (44). An ejector (40) in the housing (34) can be actuated to eject the used needle hub (16) and outer covers (22) from the first well (44) and the inner shield (24) from the second well (46) for disposal. A method of coupling a pen needle delivery device to a needle hub positions a needle hub assembly (18) in the first well (44) and inserts the coupling end of the delivery device (10) into the first well (44) and is coupled to the needle hub. The needle hub is pulled from the outer cover (22). The inner shield (24) is inserted into the second well (46) to remove the inner shield from the needle hub.
Vial Transfer and Injection Apparatus and Method
Drug delivery system, injection device, transfer apparatus, vial holder and method of administering and transferring are disclosed. The system may include transfer apparatus and an injection device. The transfer apparatus may have receiving stations for a drug source, such as a vial or vial holder, and for an injection device, and fluid flow pathways for transferring drugs from the source into the injection device. The injection device may include an expandable elastic bladder and an injection cannula that is movable between a plurality of positions.
SYSTEMS AND APPROACHES FOR STERILIZING A DRUG DELIVERY DEVICE
An on-body injector system includes a drug container assembly including a container, a seal member, and a sealing interface between the seal member and the container. The container includes an opening and the seal member at least partially covers the opening in the container. A fluid pathway assembly is coupled to the drug container assembly and includes a needle that is movable between a storage position, in which a point of the needle is spaced from the seal member, and a delivery position, in which the point of the needle is disposed at least partially through the seal member. A radiation generator is configured to emit rays of radiation to sterilize and/or disinfect the sealing interface. A barrier is disposed adjacent to the sealing interface and has an opening. At least a portion of the drug container assembly is positioned adjacent to the opening in the barrier.
Intravascular line and port cleaning methods, methods of administering an agent intravascularly, methods of obtaining/testing blood, and devices for performing such methods
A syringe assembly is provided comprising a syringe cylinder extending from an opening configured to receive a plunger to an end configured to couple with a needle and/or medical tubing, a cap configured to couple to the end, and barrier material at least partially encompassing the cap and the end. A syringe assembly is provided comprising a syringe cylinder extending from an opening configured to receive a plunger to an end configured to couple with a needle and/or medical tubing, a plunger extending from one end to a seal end, and at least one cap configured to couple to the one end. A syringe assembly is provided comprising a syringe cylinder extending from an opening configured to receive a plunger to an end configured to couple with a needle and/or medical tubing, and a plunger extending from one end to a seal end, the one end of the plunger defining a recess configured to receive at least one cap.
Packaging for medical containers
Packaging for medical containers, including a tub having a peripheral wall, a sealing cover sealable on an opening of the tub and a sealing envelope able to protect the sealing cover. The sealing envelope includes: a lower sealing part, having a frame able to be sealed to the peripheral wall of the tub, and a bonding surface that extends outwards from the frame, and an upper sealing part sealed on the bonding surface to enclose the opening of the tub and the sealing cover.
Device and method to locate site of intramuscular injection
Devices, kits and methods for determining the site of intramuscular injection in adult and child patients are disclosed. The device includes a top element and two legs that are configured to be fastened in a first position and a second position. When placed in the first position and second position, the device forms a substantially triangular region having a center that corresponds to the site of injection.
Extracorporeal oxygenation system for low flow rates and methods of use
This invention is directed to system and methods for the oxygenation of the blood of a patient, comprising an extracorporeal blood circulation path adapted to be coupled to the patient's vascular system, and comprising apparatus for oxygenating blood flowing therein and withdrawing CO2 therefrom, wherein the flow rate of blood flowing in said extracorporeal blood circulation path does not exceed 2/5 of the patient's blood flow. The extracorporeal blood circulation path preferably comprise a cartridge including an oxygenator and at least one cannula.
