Abstract

The invention relates to a medicament administration device (1) comprising a rigid medicament container (2) for a liquid medicament with an outlet (3) for the medicament, a storage means (4) for storing solid particles (5), and a feeding means for feeding solid particles (5) from the storage means (4) into the medicament container (2) to displace a dose of medicament by solid particles (5), thereby squeezing the dose of medicament through the outlet (3) of the medicament container (2). In addition the invention relates to a method for administering a liquid medicament stored in a rigid medicament container (2) with an outlet (3) for the medicament, wherein a dose of medicament is squeezed through the outlet (3) of the medicament container (2) by displacing the dose of medicament by solid particles (5) which are fed into the medicament container (2).

Claims

1. Medicament administration device comprising a rigid medicament container for a liquid medicament with an outlet for the medicament, a storage means for storing solid particles, and a feeding means for feeding solid particles from the storage means into the medicament container to displace a dose of medicament by solid particles, thereby squeezing the dose of medicament through the outlet of the medicament container.

2. Medicament administration device according to claim 1, characterized in that the medicament administration device comprises solid particles storable in the storage means.

3. Medicament administration device according to claim 2. characterized in that the solid particles are incompressible.

4. Medicament administration device according to claim 2, characterized in that the solid particles consist of a material which is inert to chemical reactions with the liquid medicament.

5. Medicament administration device according to claim 2, characterized in that the solid particles consist of glass and/or a rubber material and/or polytetrafluoroethylene.

6. Medicament administration device according to claim 2, characterized in that the solid particles are ball-shaped or cubical-shaped.

7. Medicament administration device according to claim 1, characterized in that the storage means comprises subunits for storing separately portions of solid particles.

8. Medicament administration device according to claim 1, characterized in that the feeding means comprises a piston to press solid particles out of the storage means.

9. Medicament administration device according to claim 1, characterized in that the feeding means comprise connection means connecting the storage means and the medicament container to feed solid particles from the storage means into the medicament container.

10. Medicament administration device according to claim 1, characterized by a restraining means to prevent solid particles from leaving the medicament container.

11. Medicament administration device according to claim 10, characterized in that the restraining means comprises a filter for the outlet of the medicament container, the filter (7) being impenetrable for the solid particles (5).

12. Injection arrangement for delivering a liquid medicament comprising a medicament administration device according to claim 1.

13. Injection arrangement according to claim 12, characterized in that a valve and a hollow needle for piercing a patients skin are arranged at the outlet of the medicament container.

14. Inhaler arrangement for delivering a liquid medicament comprising a medicament administration device according to claim 1.

15. Use of a medicament administration device according to claim 1 for delivering one of an analgesic, an anticoagulant, insulin, an insulin derivate, heparin, Lovenox, a vaccine, a growth hormone, a peptide hormone, a protein, antibodies or complex carbohydrates.
