Baby bottle with bottle top attachment
An apparatus comprising a baby bottle ( 2 ) and a bottle top attachment ( 4 ) coupled to the baby bottle ( 2 ) and having a connector ( 6 ) for a breast pump. The apparatus is characterized in that the bottle top attachment ( 4 ) includes a measuring head ( 8 ) with a reservoir ( 10 ) for breast milk and in that the measuring head ( 8 ) includes a sensor unit that is associated with the volume of the reservoir ( 10 ) and that enables determining a parameter of the milk expressed into the baby bottle.
1. An apparatus comprising:
a baby bottle; and
a bottle top attachment coupled to said baby bottle and having a connector for a breast pump; wherein
said bottle top attachment comprises a measuring head with a reservoir for breast milk;
said measuring head comprises an optical sensor unit configured to determine a current level of breast milk within said reservoir;
said optical sensor unit is oriented towards a cavity of the reservoir, said reservoir comprising an outflow opening to said baby bottle; and
light detectors of the optical sensor unit are arranged one above another in a height direction on one side of said reservoir and light emitters of the optical sensor unit are arranged one above another in the height direction on another side of said reservoir.
2. The apparatus according to claim 1 , further comprising a closure element disposed in said outflow opening, said closure element being adapted such that it retains at least a certain amount of milk in said reservoir.
3. The apparatus according to claim 2 , wherein the closure element is a valve that is arranged in said outflow opening, and in a closed position bears against said outflow opening of said reservoir and is forced to an open position due to a weight force of milk contained in said reservoir.
4. The apparatus according to claim 1 , wherein each light detector on the one side of the reservoir is assigned to one light emitter arranged on the other side of the reservoir at the same height.
5. The apparatus according to claim 1 , further comprising a control unit that is connected in a controlling manner to said light emitters and adapted such that said light emitters are switched on and off during a predetermined period of time and in a predetermined sequence.
6. The apparatus according to claim 5 , wherein said control unit is adapted such that switching said light emitters on and off repeats periodically.
7. The apparatus according to claim 1 , further comprising a processing unit which is adapted to determine a parameter of the milk contained in said reservoir by way of intensity measured by said light detectors.
8. The apparatus according to claim 1 , wherein a central axis (A) of said reservoir coincides with a central axis (A) of said measuring head.
9. The apparatus according to claim 1 , wherein said reservoir has a substantially rectangular cross-section.
10. The apparatus according to claim 1 , wherein said measuring head comprises an outer housing and an inner housing forming said reservoir and said outer housing being releasably connected to said inner housing.
11. The apparatus according to claim 10 , wherein said outer housing is screwed to a neck of said baby bottle by way of a thread.
12. The apparatus according to claim 10 , wherein said inner housing is screwed to said connector by way of a thread.
13. The apparatus according to claim 1 , wherein said reservoir has a substantially square cross-section.
