Abstract
Abstract A device is provided for administering medicaments in solid finely divided form to patients. The device comprises a housing (1,101), a tray (2,102) mounted in the housing (1,101) and movable between first and second positions relative to the housing, a support disc (3, 103) provided on the tray and adapted to receive a carrier (5) provided with at least one med- icamentcontainer. A plunger (18,118) is operableto penetrate a container registered therewith to open the container, movement of the tray (2, 102) from its first to its second position being such as to cause the support to bring a container into registration with the plunger (18, 118). Air enters through an air inlet (17,117), and there is an outlet (27,127) through which a patient can inhale air having medicament therein.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
152 words
A device for administering medicaments in solid finely divided form to patients, comprising a housing; a tray mounted in the housing and movable between first and second positions relative to the housing; a support provided on the tray and adapted to receive, in use, a carrier provided with at least one medicament container; a plunger operable, in use, to penetrate a container registered therewith to open the container, movement of the tray from its first to its second position being such as to cause, in use, the support to bring a container into registration with the plunger; an air inlet through which, in use, air can enter the device, and an outlet through which a patient can inhale, whereby medicament will be released from an opened container and entrained in an air flow produced by the patient, air entering the air inlet and passing out through the outlet having entrained medicament therein.
Claim 2
Independent Claim
152 words
A device for administering medicaments in solid finely divided form to patients, comprising a housing; a tray mounted in the housing and movable between first and second positions relative to the housing; a support provided on the tray and adapted to receive, in use, a carrier provided with at least one medicament container; a plunger operable, in use, to penetrate a container registered therewith to open the container, movement of the tray from its first to its second position being such as to cause, in use, the support to bring a container into registration with the plunger; an air inlet through which, in use, air can enter the device, and an outlet through which a patient can inhale, whereby medicament will be released from an opened container and entrained in an air flow produced by the patient, air entering the air inlet and passing out through the outlet having entrained medicament therein.
Claim 3
Dependent Claim
29 words
A device according to claim 1, wherein the support is rotatably mounted on the tray to receive a carrier having a plurality of medicament containers arranged in a circle.
Claim 4
Dependent Claim
41 words
A device according to claim 2, wherein indexing means are provided operably by movement of the tray from its first to its second position to cause the support to be indexed to bring the next container into registration with the plunger.
Claim 5
Dependent Claim
39 words
A device according to claim 1 or 2, wherein the support is in the form of a disc having a plurality of apertures therethrough, the apertures being arranged in a circle so that each receives a respective medicament container.
Claim 6
Independent Claim
95 words
A device according to any one of claims 2 to 4, wherein the plunger is of such a length that it completely penetrates the container aligned therewith to produce an air flow passage therethrough and wherein the support has a plurality of ribs on a face thereof, the ribs cooperating with means provided on the housing adjacent the said outlet to define, together with said passage through the container, a substantially isolated air flow path which leads from the side of the container nearer the plunger, through the container and thence to the said outlet.
Claim 7
Dependent Claim
20 words
A device according to claim 1, wherein the support is adapted to receive a carrier having a single medicament container.
Claim 8
Dependent Claim
18 words
A device according to claim 6, further comprising a magazine adapted to receive at least one further carrier.
Claim 9
Independent Claim
34 words
A device according to any preceding claim, wherein the housing has a base member and a lid pivotally mounted thereon for pivotal movement about an axis between a closed position and an open position.
Claim 10
Dependent Claim
15 words
A device according to claim 8, wherein the said plunger is carried by the lid.
Claim 11
Dependent Claim
14 words
A device according to claim 9, wherein the plunger is located adjacent said axis.
Claim 12
Dependent Claim
44 words
A device according to claim 9 or 10, wherein the plunger is arranged to penetrate a container when the lid is moved to its open position and to leave the container when the lid is moved from its open position towards its closed position.
Claim 13
Independent Claim
35 words
A device according to any one of claims 8 to 11, wherein the plunger is curved in a direction such as to reduce the size of hole which it produces in the container on penetration.
Claim 14
Independent Claim
55 words
A device according to any preceding claim; wherein the second tray position is such that the tray moves outwardly with respect to the housing from the first position to the second position and wherein the tray has a third position, outwardly from the second position, in which a carrier can be received by the support.
Claim 15
Dependent Claim
23 words
A device according to claim 13, wherein the third tray position is one in which the tray is completely removed from the housing.
Claim 16
Independent Claim
