Drug cassette, autoinjector, and autoinjector system
First Claim
1. A cassette for an injector, the cassette comprising:
- a housing; and
a body member having a fluid chamber for containing a drug and an injection needle in fluid communication with the fluid chamber, the body member moveable in the housing between a proximal position and a distal position;
a locking arrangement for interlocking the body member with the housing, the locking arrangement comprising a spring-biased member associated with one of the housing and the body member, and a fixed member associated with the other one of the housing and the body member for interlocking with the spring-biased member;
wherein the locking arrangement further comprises a cam for unlocking the spring-biased and fixed members;
wherein the cam is actuated by the injector during a needle-insertion cycle of the injector.

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 an integrated cassette syringe movably disposed within the housing, for holding a drug, and a locking arrangement for interlocking the integrated cassette syringe with the housing. The cassette may further have an aperture in the housing, and a cassette cap for removing a needle shield of the integrated cassette syringe. 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.

43. A cassette for an injector, the cassette comprising:
-
a housing; a body member having a fluid chamber for containing a drug and an injection needle in fluid communication with the chamber, the body member moveable in the housing between a proximal position and a distal position; and a locking arrangement for interlocking the body member with the housing, the locking arrangement comprising a spring-biased member associated with one of the housing and the body member, and a fixed member associated with the other one of the housing and the body member for interlocking with the spring-biased member, wherein the locking arrangement further comprises; a cam for unlocking the spring-biased and fixed members; and a second cam for preventing the spring biased member from interfering with the assembly of the body member to the housing, wherein the second cam is disposed on a hand member connected to the one of the housing and the body member.

44. A cassette for an injector, the cassette comprising:
-
a housing; a body member having a fluid chamber for containing a drug and an injection needle in fluid communication with the fluid chamber, the body member moveable in the housing between a proximal position and a distal position; 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 housing, embedded within the housing, provided on or in a separate structure contained within the housing, or any combination thereof; wherein the cassette ID comprises a contact system that requires contact between the cassette ID and the injector, the contact system comprises one or more electrically conductive strips for contacting one or more sensing elements of a detector of the injector when the cassette is placed in or on the injector, and each of the one or more electrically conductive strips defines a straight or tortuous path, the code at least partially determined by the path of each of the one or more electrically conductive strips.
