Systems and devices described herein include multi-dose injection systems for delivering drugs, hormones, biologics, and other therapeutic agents. Systems include multiple single-injection needle connectors attachable to a reusable injector. The needle connectors include a needle having a distal end for administering the therapeutic agent to the patient and a proximal end to pierce a septum of the reusable injector. The proximal ends of the needles across the multiple needle connectors can vary such that the piercing location on the septum varies. The systems also include modular needle connectors. The modular needle connectors can include a disk rotatable within a connector body. A position of a needle within the rotatable disk changes each time the modular needle connector is connected to a reusable injector.

Disclosed is a packaging for a number of pre-filled drug cartridges comprising a body to which an infusion set with tubing and needle can be fitted, the body having an open rear end, wherein a stopper is slidably disposed within the body, wherein a peg is arranged on the packaging, the peg having a height which is such that when a cartridge is being put on the peg with the rear end and pushed against it until the rear end abuts a surface of the packaging, the stopper is moved within the body by such a distance that a predetermined volume of a medicament is displaced from the cartridge for priming the cartridge and infusion set.

An apparatus includes a syringe body, a plunger, a cap, and a dose gauge. The syringe body defines a volume configured to contain a medicament. The dose gauge is disposed about at least a portion of a side wall of the syringe body, and defines a window. The cap is coupled to a proximal end portion of the syringe body, and includes an engagement portion. The plunger has a distal end portion configured to move within the volume to convey the medicament. An engagement portion of the plunger is configured to interface with the engagement portion of the cap to prevent rotation of the plunger about a longitudinal axis of the plunger. An outer surface of the plunger includes a series of indicia. At least one of the indicium is visible through the window when the plunger is in a first position within the volume.

A syringe assembly including: (1) a syringe barrel defining a chamber; (2) a plunger mounted in the chamber and moveable with respect to the barrel; and (3) a cap holder assembly containing a cap and an absorbent material removably attached to the syringe.

A medication delivery device included molded cylindrical barrel having visual marks on the surface of the barrel in the axial direction, a plunger seals the distal opening of the cylindrical barrel, a molded needle hub disposed in the proximal opening of the cylindrical barrel for sealing the needle hub to the barrel. A needle is disposed in the needle hub for communicating liquids by operation of the plunger in the axial direction. The circumferential surface on the flange of the needle hub comprises a colored mark that corresponds to a characteristic of the medication delivery device or its contents.

Systems and methods encourage users to rotate injection sites and avoid lipodystrophy. Sleeves and/or lost-tooth gear dials and/or microswitches in or on injection pens or their caps, on vials, and on other portable devices manually adjust an indicator before or after an injection to show a current or next injection site in accordance with a site rotation plan. Injected medicine packaging and related printed indicia encourage site rotation. Optical devices employing optical mouse or projection technology help locate and/or distribute injection sites within a body area. A mobile phone app tracks injections and locations to select next injection site, and can use imaging to locate a target injection site and optionally diagnose lipodystrophic conditions and record them. Tactile and print media educational tools are presented to help users palpate and identify lipos in body areas having injection sites.

An injection system includes a handle assembly with a handle body having an outer surface surrounding a handle body interior and a plunger extending therethrough. A tubular handle collar is telescopically received in the handle body exterior and is axially movable with respect to the handle body. A syringe housing assembly is selectively connectable to the handle assembly and includes a syringe housing and a tubular syringe sleeve telescopically received through a distal end of the syringe housing and axially movable with respect thereto. The syringe housing has an exterior side surface surrounding a syringe housing interior configured to receive at least a portion of a syringe. The syringe sleeve has a proximal end, a distal end with a skin contact surface, and a generally cylindrically-shaped outer surface.

The present invention disclosed a simply packaged pen needle and methods of use, comprising of at least one needle body and at least one packaging body used to package said needle body, where said needle body is comprised of a needle hub, a cannula, and an inner protective cap connected consecutively, said packaging body comprises of a packaging cup and the sealing paper, said packaging cup comprises of at least one chamber coupled with said needle body, said needle hub comprises of at least one axial protrusion on its outer circumference, the inner wall of said chamber comprises of at least one groove coupled with the axial protrusion, the upper edge of said chamber is a flat surface, said sealing paper connects with the flat surface. As a result, this simply packaged pen needle and methods of use will simplify the entire manufacturing and sealing processes, significantly enhance the reliability of sterile sealing, greatly reduce product cost, especially suitable for mass production, thus is of great economic value.

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.

A container for enclosing a medical device is disclosed, and in one form includes a flexible sheet bearing an adhesive layer which is deposited on a portion thereof, and wherein the flexible sheet can be folded or closed in a manner so as to create a cavity which receives a medical device therein, and which further allows a clinician to determine if the medical device has been accessed or tampered with by an unauthorized individual.
