Abstract

The invention provides an adaptor for a medicament delivery device is configured to enable a set dosage of a medicament to be drawn into and/or expelled from the device, the adaptor including: a body configured to be coupled to the device; an attachment portion movable with respect to the body and configured for attachment with a first part of the device; an engaging portion movable with the attachment portion; and a receiver configured to receive a movement constraint guide (MCG) and facilitate engagement between the engaging portion and the MCG; wherein the MCG includes one or more physical features defining at least an aspect of the set dosage; and wherein activation of said first part of the device to draw and/or expel the medicament is stopped when the set dosage is reached by engagement between the engaging portion and at least one of the one or more physical features of the MCG. The invention thus allows ready control of one or more aspects of dosage administration, which can be the amount of a dose and/or or the repeats of a dose.

First claim

1 . An adaptor for a medicament delivery device, the adaptor configured to enable a set dosage of a medicament to be drawn into and/or expelled from the device, the adaptor including:
a body configured to be coupled to the device; an attachment portion movable with respect to the body and configured for attachment with a first part of the device; an engaging portion movable with the attachment portion; and a receiver configured to receive a movement constraint guide (MCG) and facilitate engagement between the engaging portion and the MCG; wherein the MCG includes one or more physical features defining at least an aspect of the set dosage; and wherein activation of said first part of the device to draw and/or expel the medicament is stopped when the set dosage is reached by engagement between the engaging portion and at least one of the one or more physical features of the MCG.

2 . The adaptor of claim 1 , wherein the medicament delivery device is a syringe for delivery of a fluid medicament, said first part of the device being a syringe plunger, wherein activation of said first part of the device being movement of the syringe plunger.

3 . The adaptor of claim 1 , wherein the medicament delivery device is a receptacle for delivery of medicament in solid or part-solid form, said first part of the device comprising a mechanism to dispense the medicament elements in prescribed quantities, activation of said first part of the device being operation of said dispensing mechanism.

4 . The adaptor of claim 1 , wherein the MCG is a planar element, the receiver having a complementary shaping to receive said element.

5 . The adaptor of claim 4 , wherein the MCG is a suitably shaped card.

6 . The adaptor of claim 1 , wherein the MCG carries or is formed with one or more tracks providing said one or more physical features for guiding movement of a part of said engaging portion and thus movement of said first part of the device.

7 . The adaptor of claim 1 , wherein the engaging portion and the attachment portion are provided as a single unit, selected from the group of an integral unit and an assembly of parts.

8 . The adaptor of claim 1 , wherein the set dosage is a single dose or a prescribed dosing regime whereby the MCG is configured to delimit more than one dose.

9 . The adaptor of claim 1 , wherein the engaging portion is adapted to be directly coupled to the attachment portion.

10 . The adaptor of claim 1 , wherein the one or more physical features are protrusions or recesses on a surface of the MCG that provide abutment surfaces for the engaging portion.

11 . The adaptor of claim 1 , wherein the MCG includes one or more smart features configured to provide patient specific information to an external device.

12 . The adaptor of claim 1 , wherein the adaptor includes a second engaging portion movable in relation to the first engaging portion and configured to engage one or more additional physical features of the MCG.

13 . The adaptor of claim 12 , wherein engagement between the second engaging portion and the one or more additional physical features of the MCG provides a different aspect of the set dosage to engagement between the first engaging portion and the one or more physical features of the MCG.

14 . The adaptor of claim 12 , wherein the first engaging portion is configured to move along a first track of the MCG and the second engaging portion is configured to move along a second track of the MCG, wherein the first track defines a dosage volume of the set dosage and the second track defines a number of dosages of the set dosage.

15 . The adaptor of claim 14 , wherein the adapter includes a retaining structure mounted to the body, adjacent the second track, the retaining structure configured to limit the second engaging portion to incremental movement along said second track, each increment associated with one dosage.

16 . The adaptor of claim 15 , wherein the retaining structure is a sawtooth rack, the incremental movement of the second engaging portion being controlled by the interaction between the second engaging portion and the successive teeth of the sawtooth rack.

17 . A method for controlling medicament administration, including:
recording prescription information regarding a medicament, a dosage and a patient to whom the medicament is to be administered; providing for production of a movement constraint guide (MCG), the MCG including: one or more physical features defining at least an aspect of the dosage; and one or more readable identification features including one or more pieces of the prescription information; recording administration information associated with the use of the MCG with a medicament delivery device; the administration information including:
data produced by reading said one or more readable identification features from the MCG; and
an indication of delivery of the dosage of the medicament to the patient by way of the medicament delivery device operating under constraints imposed by the interaction of the physical features of the MCG with the medicament delivery device.

18 . A non-transitory computer-readable medium containing instructions which when executed on a processor enables performance of the method of claim 17 .
