Device for administering an injectable product in doses

1. A device for administering an injectable product in doses, said device comprising:

a casing;

a container for the product, accommodated by the casing;

an appliance for delivering the product from the container, wherein the appliance comprises a piston;

a drive motor for the moving the appliance;

a pressure sensor for monitoring operational pressures associated with the product, wherein the pressure sensor comprises a force sensor that measures a reaction force exerted by the piston; and

a vibrator motor associated with the casing, said vibrator motor operably coupled to and triggered by the sensor, such that it vibrates when an operational pressure condition occurs.

2. The device as set forth in claim 1 , wherein the force sensor comprises a bending beam with a thin-film strain measuring strip.

3. The device as set forth in claim 1 , wherein the casing comprises casing walls and a sliding platform mounted floating on the casing walls in the casing, the reaction force being transferred to the force sensor via the sliding platform.

4. A device for administering an injectable product in doses, said device comprising:

a) a casing;

b) a container for the product, accommodated by the casing;

c) a delivering appliance for delivering the product from the container, wherein the appliance comprises a piston;

d) a drive means for the delivering appliance;

e) a pressure sensor adapted to monitor pressure associated with the product, wherein the pressure sensor comprises a force sensor that measures a reaction force exerted by the piston; and

f) and a means for determining a malfunction of the device, wherein

g) a vibrator motor is accommodated by the casing, said vibrator motor being triggered by the means for determining a malfunction such that it generates a vibrating alarm signal when a malfunction is determined.

5. The device as set forth in claim 4 , wherein the force sensor comprises a bending beam with a thin-film strain measuring strip.

6. The device as set forth in claim 4 , wherein the casing comprises casing walls and a sliding platform mounted floating on the casing walls in the casing, the reaction force being transferred to the force sensor via the sliding platform.

7. A device for administering an injectable product in doses, said device comprising:

a) a casing;

b) a container for the product, accommodated by the casing;

c) a delivering anpliance for delivering the product from the container, wherein the appliance comprises a piston;

d) a drive means for the delivering appliance;

e) a pressure monitoring means adapted to monitor pressure associated with the product, wherein the pressure monitoring means comprises a force sensor that measures a reaction force exerted by the piston;

f) and an input means for inputs to the device from a user, wherein

g) a vibrator motor is accommodated by the casing;

h) the input means is connected to the vibrator motor; and wherein

i) when the input means confirms an input, the vibrator motor is triggered and as confirmation of an input generates a vibrating signal which is characteristic of the input.

8. The device as set forth in claim 7 , wherein the force sensor comprises a bending beam with a thin-film strain measuring strip.

9. The device as set forth in claim 7 , wherein the casing comprises casing walls and a sliding platform mounted floating on the casing walls in the casing, the reaction force being transferred to the force sensor via the sliding platform.
