Abstract
Abstract The application describes an administering device, in particular a self-injecting device, comprising a body for holding a container of a substance to be administered, a release mechanism, and means controlled by the release mechanism to discharge the said substance. The body is formed of two parts, one part being movable relative to the other, wherein one part has a trigger and the said release mechanism is partly actuated by the operation of a trigger of the said one part and partly actuated by movement of the other part relative to the said one part, but is only wholly actuated by both the operation of the trigger and the movement of the other part. Thus the discharge means cannot be accidentally actuated.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
175 words
An administering device comprising: a body for holding a container of substance to be administered, a release mechanism, means controlled by the release mechanism to discharge the said substance, and a trigger, the release mechanism being capable of releasing the discharge means by cooperating with the trigger; wherein the body is formed of two parts, a first part and a second part, the two parts being movable relative to one another along a predetermined axis between a first and a second position; wherein the trigger is mounted on the first part and the release mechanism is is mounted on the second part; whereby the trigger is movable substantially along said predetermined axis between the first position and the second position in a direction towards the release mechanism; wherein, in the second position, the release mechanism is nearer to the trigger than in the first position; and wherein only in the second position is the trigger capable of cooperating with the release mechanism to release the discharge means, whereby the discharge means cannot be accidentally released.
Claim 2
Dependent Claim
175 words
An administering device comprising: a body for holding a container of substance to be administered, a release mechanism, means controlled by the release mechanism to discharge the said substance, and a trigger, the release mechanism being capable of releasing the discharge means by cooperating with the trigger; wherein the body is formed of two parts, a first part and a second part, the two parts being movable relative to one another along a predetermined axis between a first and a second position; wherein the trigger is mounted on the first part and the release mechanism is is mounted on the second part; whereby the trigger is movable substantially along said predetermined axis between the first position and the second position in a direction towards the release mechanism; wherein, in the second position, the release mechanism is nearer to the trigger than in the first position; and wherein only in the second position is the trigger capable of cooperating with the release mechanism to release the discharge means, whereby the discharge means cannot be accidentally released.
Claim 3
Dependent Claim
25 words
An administering device according to claim 1, wherein said second part is slidably mounted within said first part and extends out of said first part.
Claim 4
Dependent Claim
51 words
An administering device according to claim 2, wherein the release mechanism is mounted at an end of the second part, the trigger of the first part being in the form of a push button towards which the release mechanism is moved by movement of the second part with the first part.
Claim 5
Dependent Claim
62 words
An administering device according to claim 3, wherein the container is a syringe held within the said second part and wherein actuation of the discharge means firstly moves the syringe forward within the second part to expose the needle, and thus to urge it through the skin, and secondly depresses the plunger of the syringe to administer the substance to the user.
Claim 6
Dependent Claim
59 words
An administering device according to claim 4, wherein the discharge means is an elongate pusher rod which is urged by means of a resilient force and wherein the release mechanism comprises a pair of arms over which the end of the pusher rod is held, the rod being released by relative movement of the button to separate the arms.
Claim 7
Dependent Claim
70 words
An administering device according to claim 5, wherein the one part of the device which moves within the other is itself comprised of two parts, a first part extending out of the device and being in the form of a sleeve which houses the syringe and a second part within the device which houses the pusher rod, the first and second parts of the one part being releasably connectable together.
Claim 8
Dependent Claim
34 words
An administering device according to claim 6, wherein the said sleeve comprises an inner and an outer sleeve part, the sleeve parts being movable relative to each other against the action of a spring.
Claim 9
Dependent Claim
25 words
An administering device according to claim 1, wherein the administering device is elongate and generally cylindrical and thus is similar to a pen in shape.
Claim 10
Dependent Claim
26 words
An administering device according to claim 1, wherein the said substance is a pharmaceutical substance useful in treating migraine and related disorders such as cluster headache.
Claim 11
Dependent Claim
13 words
An administering device according to claim 9, wherein the pharmaceutical substance is sumatriptan.
Claim 12
Dependent Claim
85 words
A combination of an administering device according to claim 1 and a housing for at least one container of the substance to be discharged, the housing comprising a removable sleeve for the container and means releasably holding the sleeve within the housing, the said sleeve having means to releasably attach itself to the first part of the administering device, whereby the sleeve and container can be removed from the housing by co-operation with the administering device and can be returned to the housing after use.
Claim 13
Dependent Claim
22 words
A combination according to claim 11, wherein the housing has a lid which is closed after the used container is returned thereto.
Claim 14
Dependent Claim
34 words
A combination according to claim 11, wherein the container is a syringe having a rubber cap protecting the needle, this cap remaining within the housing when the sleeve is removed by the administering device.
Claim 15
Dependent Claim
20 words
A combination according to claim 13, wherein the syringe is held within the sleeve against the action of a spring.
Claim 16
Dependent Claim
39 words
A combination according to claim 11, together with a casing for the combination, the casing having a recess for the administering device, the recess including means to prime the release mechanism when the device is placed into the recess.
Claim 17
Dependent Claim
61 words
An administering device according to claim 1, wherein the container is moveable within the body against the discharge means and wherein the device further comprises means to prevent discharge of the substance until the discharge means is engaged by the release mechanism, whereby the loading of the container into the body can simultaneously engage the discharge means with the release mechanism.
Claim 18
Dependent Claim
40 words
An administering device according to claim 16, wherein the container is a syringe and a rubber cap is provided over the syringe needle to seal the syringe so that the syringe itself can be used to move the discharge means.
