Abstract
Abstract An insufflator for administering pre-dosed powder drugs contained in opercula, which comprises a body (6) having an air-inlet opening (7) and a substantially vertical outlet channel (8) for the air carrying the powder drug, and a device with opposite pins (18,19) of a known kind for puncturing the operculum (15), said operculum (15) being placed in a suitable seat (14). The latter is provided in a member (13) that is turnable relative to said body (6). Said turnable member can take at least two different positions: a first position, where the operculum (15) can be axially punctured by the above-mentioned opposite, substantially horizontal pins (18,19); and a second position, turned 90° relative to said first position, where the opposite holes that have been pierced in the operculum (15) are coaxial with said air-outlet channel (8).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
188 words
Insufflator for the administering drugs which are in the form of a powder pre-dosed into opercola, the insufflator comprising a body having an air-inlet opening and a substantially vertical outlet channel for the air carring the powder drug, and a device with opposite pins of a known kind for puncturing the operculum, said operculum being placed in a suitable seat, characterized in that the seat for the operculum is provided in a member that is turnable relative to said body, and in that said turnable member can take at least two different positions: a first position, or operculum puncturing position, where the operculum can be axially punctured by the opposite, substantially horizontal pins of the above-mentioned puncturing device; and a second position, or delivery position, that is substantially turned 90° relative to said first position, the opposite holes that have been pierced in the operculum now being coaxial with said air-outlet channel, in said second position the lower end of the air-outlet channel being in communication with the top of the seat of the operculum, while the bottom of said seat is in communication with the air-inlet opening.
Claim 2
Dependent Claim
188 words
Insufflator for the administering drugs which are in the form of a powder pre-dosed into opercola, the insufflator comprising a body having an air-inlet opening and a substantially vertical outlet channel for the air carring the powder drug, and a device with opposite pins of a known kind for puncturing the operculum, said operculum being placed in a suitable seat, characterized in that the seat for the operculum is provided in a member that is turnable relative to said body, and in that said turnable member can take at least two different positions: a first position, or operculum puncturing position, where the operculum can be axially punctured by the opposite, substantially horizontal pins of the above-mentioned puncturing device; and a second position, or delivery position, that is substantially turned 90° relative to said first position, the opposite holes that have been pierced in the operculum now being coaxial with said air-outlet channel, in said second position the lower end of the air-outlet channel being in communication with the top of the seat of the operculum, while the bottom of said seat is in communication with the air-inlet opening.
Claim 3
Dependent Claim
17 words
Insufflator as claimed in claim 1, characterized in that the turnable member is detachable from said body.
Claim 4
Dependent Claim
25 words
Insufflator as claimed in claim 2, characterized in that the turnable member is housed in a cylindrical cavity provided in said body and coaxial therewith.
Claim 5
Dependent Claim
54 words
Insufflator as claimed in claim 3, characterized in that on the bottom of the cylindrical cavity there is provided a pusher that can be reciprocated parallel to the axis of rotation of the turnable member and can be operated from outside the body to ease the separation of the turnable member from said body.
Claim 6
