Abstract

A device to prepare and administer a two-component mixture, including a first chamber in which a container is housed that is hermetically closed for a liquid component, a second chamber containing a powdered component, an opening of the container of the liquid component, a mixing member placed in the second chamber for preparing the mixture and a piston able to move in the second chamber to dispense the mixture. The mixing member includes a stem, passing through an opening for dispensing the mixture in the second chamber, having an outer end equipped with a handle and an inner end provided with a mixing blade connected to the inner end with a releasable connection.

Claims

1. A method for preparing and administering a two-component mixture, actuated with a device, wherein the method comprises the following steps:

breaking a container of a liquid component;

transferring the liquid component from a first chamber to a second chamber;

mixing the liquid component and a powdered component through a mixing member, making a mixture;

removing a stem of said mixing member; and

acting upon a piston to dispense said mixture.

2. The method of claim 1, wherein the container is housed in the first chamber that is hermetically closed for the liquid component.

3. The method of claim 1, wherein the second chamber contains the powdered component and communicates with said first chamber.

4. The method of claim 1, further comprising means for opening said container of the liquid component and wherein the mixing member is associated with said second chamber for preparing the mixture.

5. The method of claim 1, wherein the piston is able to move in said second chamber to dispense the mixture.

6. The method of claim 1, wherein said mixing member comprises means for actuating the mixing member itself, said actuation means being able to be actuated from outside of the device, said actuation means and said mixing member being associated through releasable connection means.

7. The method according to claim 1, wherein said step of transferring the liquid component from said first chamber to said second chamber is carried out through traction towards the outside of said piston.

8. The method according to claim 1, wherein said step of mixing the liquid component and the powdered component is carried out through alternative rotary and translation movements of said mixing member inside said second chamber.

9. The method according to claim 1, wherein said step of breaking said container is carried out by pressing manually on said fracturing member.

10. The method according to claim 1, further comprising a step of connecting a recipient for collecting the dispensed mixture to said device.

11. A method for preparing and administering a two-component mixture, actuated with a device, wherein the method comprises the following steps:

breaking a container of a liquid component;

transferring the liquid component from a first chamber to a second chamber;

mixing the liquid component and a powdered component through a mixing member, making a mixture;

removing a stem of said mixing member; and

acting upon a piston to dispense said mixture from the same opening through which the mixing member passes and is actuated.

12. The method of claim 12, wherein the container is housed in the first chamber that is hermetically closed for the liquid component.

13. The method of claim 12, wherein the second chamber contains the powdered component and communicates with said first chamber.

14. The method of claim 12, further comprising means for opening said container of the liquid component and wherein the mixing member is associated with said second chamber for preparing the mixture.

15. A method for preparing and administering a two-component mixture, actuated with a device, wherein the method comprises the following steps:

breaking a container of a liquid component;

transferring the liquid component from a first chamber to a second chamber;

mixing the liquid component and a powdered component through a mixing member, making a mixture;

wherein said mixing member comprises means for actuating the mixing member itself, said actuation means being able to be actuated from outside of the device, said actuation means and said mixing member being associated through releasable connection means;

removing a stem of said mixing member; and

acting upon a piston to dispense said mixture.

16. The method of claim 16, wherein the container is housed in the first chamber that is hermetically closed for the liquid component.

17. The method of claim 16, wherein the second chamber contains the powdered component and communicates with said first chamber.

18. The method of claim 16, further comprising means for opening said container of the liquid component and wherein the mixing member is associated with said second chamber for preparing the mixture.

19. The method of claim 16, wherein the piston is able to move in said second chamber to dispense the mixture.
