Abstract

A lactation system is disclosed. Embodiments include at least one extraction mechanism including a compression mechanism and a collection mechanism, and a controller. The compression mechanism can include a plurality of manipulable members, each operably coupled to an actuator and arrangeable circumferentially about a breast of a user such that each member can be actuated to selectively apply pressure to a region of the breast. The collection mechanism can be removably coupleable to the compression mechanism and can comprise a storage compartment to receive and store milk The controller can be operably coupleable to the actuators to cause the members to move according to a movement pattern which can be configured to stimulate the breast to induce the flow of milk from the breast and modulated based on sensor feedback. A wearable garment with an inner structure can be removably coupled to the extraction mechanism. An outer cover can be arrangeable to conceal the extraction mechanism.

First claim

What is claimed is:

1. A lactation system comprising:
a wearable garment comprising an inner structure configured to be removably coupled to at least one insert and an outer cover arrangeable to conceal the at least one insert;
a stimulation mechanism comprising a heating element configured to warm mammary glands within a breast of a user to a temperature between 35° Celsius and 42° Celsius;
each at least one insert comprising:
a compression mechanism comprising a plurality of manipulable members, each of the plurality of manipulable members operably coupled to an actuator and arrangeable circumferentially about the breast such that each of the plurality of manipulable members can be actuated to selectively apply pressure to a region of the breast, and
a collection mechanism, operably coupleable to the compression mechanism configured to be proximate a nipple of the user and comprising a storage compartment to receive and store a flow of milk from the breast; and

a controller operably coupleable to the actuators to cause the plurality of manipulable members to move according to a movement pattern, the movement pattern configured to stimulate the breast to induce the flow of milk from the breast,
wherein the movement pattern comprises mechanically compressing the breast in a burst pattern comprising applying pressure to locations at opposite positions around the breast, and
wherein the burst pattern comprises repeatedly applying an upper pressure of about 200 mmHg for about one second and a lower pressure of about 20 mmHg for about three to seven seconds.

2. The lactation system of claim 1 , wherein the movement pattern comprises mechanically compressing the breast at a pressure between 0 mmHg and 215 mmHg.

3. The lactation system of claim 1 , wherein the burst pattern comprises repeatedly applying the lower pressure for about two to four seconds.

4. The lactation system of claim 1 , wherein the movement pattern comprises repeating the burst pattern at least five times.

5. The lactation system of claim 1 , further comprising at least one sensor for detecting the flow of milk and wherein the controller is configured to modify the movement pattern based on at least the flow of milk.

6. The lactation system of claim 1 , wherein each actuator comprises at least one shape-memory alloy element configured to contract the actuator based on a received control signal.

7. The lactation system of claim 1 , further comprising an external device coupleable to the controller to provide operational parameters to configure the movement pattern.

8. The lactation system of claim 7 , wherein the external device comprises a user interface configured to: receive parameters from the user and display data received from one or more sensors to the user.

9. The lactation system of claim 1 , wherein the storage compartment comprises a connection adapted to interface with an artificial nipple for feeding an infant.
