Abstract

An automatic injector training device comprises an outer structure having i) a rearward end, ii) a forward end arranged to be engaged with an injection site of the user, and iii) an intermediate portion. A manually movable actuating member is movable between a storage position and an activated position by being manually depressed by the user. A prod member is movable within the outer structure between a retracted position and an outwardly extending position when the actuating member is manually moved between the storage position to the activated position. A spring member is disposed within the outer structure and arranged so as to move the prod member from the outwardly extending position to the retracted position when the actuating member is moved from the activated position to the storage position. The actuating member is disposed so that manual movement thereof from the storage position to the activated position moves the prod member against the bias of the spring member so that the forward end of the prod member is moved to extend outwardly from the forward end of the outer structure. Releasable locking elements are disposed within the outer structure and retain the prod member in the outwardly extending position when the actuating member is moved to the activated position and permit the prod member to be moved to the retracted position when the actuating member is moved to the storage position. A safety member is movable between a safety position wherein the safety member prevents manual movement of the actuating member and a non-safety position which permits the actuating member to be manually moved between the activated position and the storage position.

Claims

1. An automatic injector training device comprising:

an outer structure having i) a rearward end, ii) a forward end arranged to be engaged with an injection site of the user, and iii) an intermediate generally cylindrical portion disposed between said forward and rearward ends and constructed and arranged to be manually gripped by the user;

a movable manually engageable member extending outwardly from the rearward end of the outer structure and adapted to be manually engaged and depressed by the user while said intermediate portion is being gripped by the user, said engageable member being movable between a storage position and an activated position by being manually depressed by the user;

a prod member movable within said outer structure between a retracted position wherein a forward portion thereof is disposed retracted within the outer structure and an outwardly extending position wherein said forward portion thereof extends outwardly from the forward end of the outer structure, said prod member being movable from said retracted position to said outwardly extending position when said engageable member is manually moved from said storage position to said activated position and being movable from said outwardly extending position to said retracted position when said engageable member is manually moved from said activated position to said storage position;

a spring member disposed within said outer structure and arranged so as to tend to bias said prod member rearwardly within said outer structure to thus move said prod member from said outwardly extending position to said retracted position when the engageable member is moved from the activated position to the storage position, said engageable member being disposed so that manual movement thereof from said storage position to said activated position moves said prod member against the bias of said spring member so that said forward end of the prod member is moved to extend outwardly from the forward end of the outer structure;

releasable locking elements disposed within said outer structure constructed and arranged to retain said prod member in said outwardly extending position when said engageable member is moved from the storage position to the activated position and to permit said prod member to be moved by said spring member from said outwardly extending position to said retracted position when said engageable member is moved from the activated position to the storage position; and

a safety member constructed and arranged to be movable between a safety position wherein the safety member prevents manual movement of said engageable member and a non-safety position which permits the engageable member to be manually moved between said activated position and said storage position.

2. An automatic injector training device according to claim 1, wherein said safety member is constructed and arranged to be able to cooperate with said outer structure so as to be able to be secured to the outer structure and cover the forward portion of the prod member after said safety member is moved to the non-safety position so as to prevent manual contact with the forward portion of the prod member.
