US 11,944,798 B2 · Drug cassette, autoinjector, and autoinjector system

Abstract

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 detecting 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.

Dependent claims

A cassette for an injector, the cassette comprising:

an outer housing having a first proximal end including a first aperture, a first distal end disposed opposite the first proximal end, and a bottom surface including an inner sleeve locking arrangement;
an inner sleeve having a second proximal end disposed within the outer housing and including a second aperture and a second distal end opposite the second proximal end, the second distal end disposed within the outer housing and adjacent the first distal end, the inner sleeve including a cantilever lock arm comprising an unbiased state and a biased state, the cantilever lock arm engaging the inner sleeve locking arrangement in the unbiased state;
and
a cassette identification arrangement (cassette ID) defining a code containing information about the cassette, the code being detectable and decipherable by the injector, the cassette ID disposed on the outer housing, embedded within the outer housing, or provided on or in a separate structure contained within the outer housing.
