Exostructure to assist in accurate syringe injection
A syringe exostructure includes a main body which removably receives a syringe having a syringe barrel and a syringe plunger. A drive plunger is reciprocatably mounted on the main body, and a plunger bar is slidably received in an axial channel on the drive plunger. The plunger bar is configured to removably couple to the syringe plunger when the syringe is introduced into the main body. A drive pawl assembly is fixed to an upper surface of the drive plunger and transfers forward motion of the drive plunger to the plunger bar as the drive plunger is advanced and disengages from the plunger bar when the drive plunger is retracted. A locking pawl assembly is fixed to the main body and extends through a slot formed in the bottom of the axial channel in the drive plunger. The locking pawl engages the plunger bar and allows the plunger bar to be advanced by the drive plunger as the drive plunger is advanced but prevents the plunger bar from being retracted by the drive plunger as the drive plunger is retracted.

Drug cassette, autoinjector, and autoinjector system
A cassette for use with an injector has a housing, and a cassette identification arrangement (cassette ID) defining a code containing information about the cassette that is detectable and decipherable by an injector. The cassette may further have a sleeve movably disposed within the housing, for holding a drug container, and a locking arrangement for interlocking the sleeve with the housing. The cassette may further have an aperture in the housing, and a cassette cap for removing a needle shield of the drug container. The cassette may have an anti-bending structure to prevent bending or flexing of the cassette cap. The injector may have a processor for controlling operational parameters of the injector and a detector communicatively coupled with the processor for detesting and communicating the cassette ID to the microprocessor to decipher the code defined therein. Also, a method of injecting a drug into a patient with an injector, wherein the sequence of actions performed by the user are controlled. Still further, a method of treating a patient in need thereof wherein a cassette containing a drug is provided and administered to the patient using an injector.
