Device for the quick inhalation of drugs in powder form by humans suffering from asthma

Claim 1

A device for the quick inhalation of drugs in powder form by persons suffering from asthma, said drugs being contained in a capsule made of a fairly rigid, pierceable material, comprising: a first and a second hollow cylindrical body, each of said first and second hollow cylindrical bodies having a bore open at both ends, and a hollow piercing element mounted in said bore integral with said body, said hollow piercing element comprising an open-ended small cylinder and a tip mounted at one end of said small cylinder, said tip having apertures extended therethrough for the passage of air, said first hollow cylindrical body including a cylindrical sleeve for receiving the capsule mounted at one end of said bore adjacent said second hollow cylindrical body and telescopically received in said bore of said second hollow cylindrical body, the capsule being mounted in said cylindrical sleeve intermediate said tip of each piercing element, said first and said second hollow cylinder being telescopically moveable toward each other to pass at least one of the respective piercing element relative to the other piercing element between a first position in which the capsule is still in its integral condition and a second position in which both of said piercing elements are passed into the capsule whereby the apertures are inside the capsule, mutually cooperating abutting means for stopping the insertion movement of one of said first and second hollow cylindrical members into the other, a helical spring means connected to each hollow cylindrical body and surrounding each piercing element for resiliently bearing against the capsule and urging said body away from the capsule in said second position, and cooperating means for holding said first and said second hollow cylindrical bodies in said second position counteracting said springs.

Claim 2

A device for the quick inhalation of drugs in powder form by persons suffering from asthma, said drugs being contained in a capsule made of a fairly rigid, pierceable material, comprising: a first and a second hollow cylindrical body, each of said first and second hollow cylindrical bodies having a bore open at both ends, and a hollow piercing element mounted in said bore integral with said body, said hollow piercing element comprising an open-ended small cylinder and a tip mounted at one end of said small cylinder, said tip having apertures extended therethrough for the passage of air, said first hollow cylindrical body including a cylindrical sleeve for receiving the capsule mounted at one end of said bore adjacent said second hollow cylindrical body and telescopically received in said bore of said second hollow cylindrical body, the capsule being mounted in said cylindrical sleeve intermediate said tip of each piercing element, said first and said second hollow cylinder being telescopically moveable toward each other to pass at least one of the respective piercing element relative to the other piercing element between a first position in which the capsule is still in its integral condition and a second position in which both of said piercing elements are passed into the capsule whereby the apertures are inside the capsule, mutually cooperating abutting means for stopping the insertion movement of one of said first and second hollow cylindrical members into the other, a helical spring means connected to each hollow cylindrical body and surrounding each piercing element for resiliently bearing against the capsule and urging said body away from the capsule in said second position, and cooperating means for holding said first and said second hollow cylindrical bodies in said second position counteracting said springs.

Claim 4

A device for the quick inhalation of drugs in powder form by persons suffering from asthma, said drugs being contained in a capsule made of a fairly rigid, pierceable material, comprising: a first and a second hollow cylindrical body, each of said first and second hollow cylindrical bodies having a bore open at both ends, and a hollow piercing element mounted in said bore integral with said body, said hollow piercing element comprising an open-ended small cylinder and a tip mounted at one end of said small cylinder, said tip having apertures extended therethrough for the passage of air, said first hollow cylindrical body including a cylindrical sleeve for receiving the capsule mounted at one end of said bore adjacent said second hollow cylindrical body and telescopically receiving in said bore of said second hollow cylindrical body, the capsule being mounted in said cylindrical sleeve intermediate said tip of each piercing element, said first and said second hollow cylinders being telescopically movable toward each other to pass at least one of the respective piercing elements relative to the other piercing element between a first position in which the capsule is still in its integral condition and a second position in which both of said piercing elements are passed into the capsule whereby the apertures are inside the capsule, and cooperating means for holding said first and said second hollow cylindrical bodies to each other in said second position.

Claim 5

A device for the quick inhalation of drugs in powder form by persons suffering from asthma, said drugs being contained in a capsule made of a fairly rigid, pierceable material, comprising: a first and a second hollow cylindrical body, each of said first and second hollow cylindrical bodies having a bore open at both ends, and a hollow piercing element mounted in said bore integral with said body, said hollow piercing element comprising an open-ended small cylinder and a tip mounted at one end of said small cylinder, said tip having apertures extended therethrough for the passage of air, said first hollow cylindrical body including a cylindrical sleeve for receiving the capsule mounted at one end of said bore adjacent said second hollow cylindrical body and telescopically receiving in said bore of said second hollow cylindrical body, the capsule being mounted in said cylindrical sleeve intermediate said tip of each piercing element, said first and said second hollow cylinders being telescopically movable toward each other to pass at least one of the respective piercing elements relative to the other piercing element between a first position in which the capsule is still in its integral condition and a second position in which both of said piercing elements are passed into the capsule whereby the apertures are inside the capsule, and cooperating means for holding said first and said second hollow cylindrical bodies to each other in said second position.
