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 for insertion into a nostril of a horse, comprising:
an inhaler body,
a pressure generator within the inhaler body and which has a tensioning device for driving the pressure generator, and with a tensioning mechanism for tensioning the tensioning device,
wherein the tensioning mechanism has a lever gear for tensioning the tensioning device,
wherein the lever gear comprises an actuating lever with an actuating section located outside of the inhaler body for manual actuation of the lever gear, one end of the actuating lever being connected with the inhaler body at a pivot point, and an arm within the inhaler body at a position for acting on the tensioning device,
wherein the actuating lever together with the arm form an elbow lever, the arm being hinged to the actuating lever between the pivot point and said actuating section.

2. Inhaler according to claim 1 , wherein the lever gear, has at least one lever that 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 runs in a lengthwise direction of the inhaler.

4. Inhaler according to claim 1 , wherein said one end of the actuating lever is hinged to the inhaler body at said pivot point.

5. Inhaler according to claim 1 , wherein the actuating lever has a pressure position and a resting position between which the actuating lever is pivotable, and wherein the actuating lever is movable toward the inhaler body from the resting position into the pressure position.

6. Inhaler according to claim 1 , 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.

7. Inhaler according to claim 1 , wherein the lever gear is configured such that, with a force acting on the actuating section, and with increasing movement of the actuating lever in an actuating direction of the actuating lever, an increasing force results that acts on the tensioning device.

8. Inhaler according to claim 1 , wherein at least one of the lever gear and 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 said at least one of the lever gear and the actuating lever.

9. 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.

10. 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 can be tensioned and which is configured 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.

11. Inhaler according to claim 10 , 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 the lever gear, so that a force can be introduced into the tensioning device.

12. Inhaler according claim 1 , wherein the inhaler has a triggering device, wherein, when tensioning of the tensioning device is concluded, the tensioning device is securable against movement.

13. Inhaler according to claim 5 , wherein the tensioning mechanism has a reset element which is configured to tension or move the actuating lever back into the rest position.

14. Inhaler for insertion into a nostril of a horse, 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, and
wherein the inhaler is configured to release the tension device when tensioned, trigger the pressure generator and to discharge a pharmaceutical agent preparation by moving 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.

15. Inhaler according to claim 14 , wherein the inhaler has a triggering device which is configured to enable or to prevent the releasing or triggering of the tensioning device depending on a tensioning state of the tensioning device.

16. Inhaler according to claim 14 , wherein the releasing or the triggering is prevented as long as the tensioning device is not in a preset tensioning state that is ready for discharging the pharmaceutical agent preparation.

17. Inhaler according to claim 16 , wherein the releasing or the triggering by means of the tensioning part is enabled when the tensioning of the tensioning device reaches said preset tensioning state.

18. Inhaler according to claim 14 , wherein the tensioning part is moveable from the first position via a triggering point into the second position, and wherein the triggering is carried out when reaching the triggering point with the tensioning part, and wherein a distance between the first position of the tensioning part and the triggering point is less than 50% of a distance of the tensioning part between the first position and the second position.

19. Method for triggering a nebulizer or an inhaler that has a pressure generator with a tensioning device, wherein the tensioning device is configured for driving the pressure generator, wherein the method comprises the steps of:
tensioning the tensioning device by moving a tensioning part from a first position into a second position without triggering dispensing from the nebulizer or inhaler,
moving the tensioning part back into the first position again, and
afterwards moving the tensioning part again from the first position in the direction of the second position, whereby dispensing from the nebulizer or inhaler is triggered.

20. Method according to claim 19 , wherein the triggering effects at least one of
administration of a pharmaceutical agent preparation;
driving a pressure generator of the inhaler;
pressure generation with the pressure generator;
discharging pharmaceutical agent preparation; and
generating aerosol with the inhaler.

21. Inhaler according to claim 1 , wherein at least one of the lever gear and the actuating lever is configured in such a way that a force that acts on an actuating section results in an increased force on the tensioning device due to said elbow lever.

22. Inhaler according to claim 14 , wherein the releasing or the triggering is prevented as long as the tensioning device is as long as the inhaler is ready for discharging the pharmaceutical agent preparation.

23. Inhaler according to claim 14 , wherein the inhaler is configured to block at least one of the pressure generator, the tension device when tensioned, and discharge of a pharmaceutical agent preparation in the inhaler.
