Abstract

An inhaler, preferably for insertion into a nostril, in particular a horse's nostril, with a pressure generator, which has a tensioning device for the drive, and with a tensioning mechanism for tensioning the tensioning device, whereby the tensioning mechanism has a lever gear for tensioning the tensioning device.

First claim

What is claimed is:

1. Inhaler, comprising:
an inhaler body,
a pressure generator in the inhaler body,
a tensioning device for driving the pressure generator, and
a tensioning mechanism for tensioning the tensioning device, the tensioning mechanism being constructed in a manner producing a gear reduction effect that decreases the force required for tensioning of the tensioning device while tension of the tensioning device is increased during preparation of the pressure generator for producing a discharge from the inhaler, said tensioning mechanism comprising a lever which is operable for both tensioning of the tensioning device and release of the tensioning to produce discharge from the inhaler,
wherein the lever drives a lever gear for tensioning the tensioning device,
wherein the lever gear has an elbow lever which has two lever arms one end of which is connected to said lever by a joint, and
wherein the elbow lever is configured for direct introduction of force into a pump device of the pressure generator.

2. Inhaler according to claim 1 , wherein the lever gear is configured for at least one of gear reduction and force increase.

3. Inhaler according to claim 1 , wherein the elbow lever produces a direction of movement that acts on the tensioning device in a direction that is axial.

4. Inhaler according to claim 1 , wherein the lever is an actuating lever which has an actuating section for manual actuation thereof.

5. Inhaler according to claim 4 , wherein the actuating lever drives the lever gear for tensioning the tensioning device and wherein the lever gear is configured such that a force acting on the actuating section and increasing deviation of the actuating lever in an actuating direction of the actuating lever results in an increasing force that acts on the tensioning device.

6. Inhaler according to claim 4 , wherein the actuating lever is configured in such a way that a force that acts on the actuating section results in an increased force on the tensioning device due to the lever gear.

7. Inhaler according to claim 1 , wherein the lever is an actuating lever and wherein the actuating lever is configured to increase a force that acts on an actuating section of the actuating lever such that the increased force tensions the tensioning device.

8. Inhaler according to claim 1 , wherein the pressure generator is configured to at least one of pressurize and spray a pharmaceutical agent preparation by energy stored in the tensioning device.

9. Inhaler according to claim 1 , wherein the pressure generator has a pump device which is axially movable by the lever gear by which the tensioning device is configured to be tensioned, the pump device being adapted to convey a pharmaceutical agent preparation out of a discharge nozzle in the case of a movement of the pump device caused by the tensioning device.

10. Inhaler, comprising:
an inhaler body,
a pressure generator in the inhaler body,
a tensioning device for driving the pressure generator, and
a tensioning mechanism for tensioning the tensioning device, the tensioning mechanism being constructed in a manner producing a gear reduction effect that decreases the force required for tensioning of the tensioning device while tension of the tensioning device is increased during preparation of the pressure generator for producing a discharge from the inhaler, said tensioning mechanism comprising a lever which is operable for both tensioning of the tensioning device and release of the tensioning to produce discharge from the inhaler,
wherein the lever is an actuating lever, and
wherein the actuating lever has a pressure position and a resting position between which the actuating lever is pivotable.

11. Inhaler, comprising:
an inhaler body,
a pressure generator in the inhaler body,
a tensioning device for driving the pressure generator, and
a tensioning mechanism for tensioning the tensioning device, the tensioning mechanism being constructed in a manner producing a gear reduction effect that decreases the force required for tensioning of the tensioning device while tension of the tensioning device is increased during preparation of the pressure generator for producing a discharge from the inhaler, said tensioning mechanism comprising a lever which is operable for both tensioning of the tensioning device and release of the tensioning to produce discharge from the inhaler, wherein the lever is an actuating lever,
wherein the lever is an actuating lever which has an actuating section for manual actuation thereof, and
wherein a lever gear has an elbow lever which is pivotably mounted in the inhaler and has a short lever arm and a long lever arm, one lever arm being pivotably connected to the actuating lever and the other lever arm acting on the pressure generator.

12. Inhaler, comprising:
an inhaler body,
a pressure generator in the inhaler body,
a tensioning device for driving the pressure generator, and
a tensioning mechanism for tensioning the tensioning device, the tensioning mechanism being constructed in a manner producing a gear reduction effect that decreases the force required for tensioning of the tensioning device while tension of the tensioning device is increased during preparation of the pressure generator for producing a discharge from the inhaler, said tensioning mechanism comprising a lever which is operable for both tensioning of the tensioning device and release of the tensioning to produce discharge from the inhaler, wherein the lever is an actuating lever,
wherein the lever is an actuating lever which has an actuating section for manual actuation thereof, and
wherein a lever gear has an arm which is hinged on the actuating lever at a first end, wherein the arm comprises a second end facing away from the first end which is configured to introduce force into the tensioning device and to tension the tensioning device.

13. Inhaler according to claim 12 , wherein the pressure generator has a pump device, wherein the pump device has a receptacle or a stop for the arm, wherein the tensioning mechanism is configured so that the arm acts on the pump device in a tensioning movement of a lever gear, so that at least one of a force can be introduced into the tensioning device and the arm can be detached from the pump device in a movement of the actuating lever in the direction of its resting position.

14. Inhaler, comprising:
a pressure generator having a tensioning device for driving the pressure generator, wherein the tensioning device is tensionable by moving a tensioning part from a first resting position of the tensioning part into a second pressurizing position of the tensioning part without producing a discharge from the inhaler,
wherein the inhaler is configured to require for each discharge of a pharmaceutical agent preparation, movement of the tensioning part from the second position into the first position followed by a discharge producing movement of the tensioning part from the first position toward the second position again so that two movements of the tensioning part from the first position towards the second position are required for each discharge of the inhaler.

15. Inhaler according to claim 14 , wherein the inhaler is configured to release the tensioned tensioning device and trigger the pressure generator by moving of the tensioning part from the second position into the first position, and then moving the tensioning part from the first position toward the second position again.

16. Inhaler according to claim 14 , further comprising means for blocking at least one of the pressure generator, the tensione
