Lactation aid and breast tissue therapeutic device
A lactation aid is disclosed having an outer layer defining a cavity and a core material located in the cavity, the core material being adapted to be one or more of: heated and cooled. The lactation aid is adapted to be manually rolled over a breast. The lactation aid may include protrusions, which protrusions may be hollow such that core material at least partially extends into the protrusions. A temperature indicator may also be present. The lactation aid may combine three therapeutic components: application of temperature (heating or cooling), movement and compression to breast tissue.
1 . A breast aid comprising:
an outer layer defining a cavity, the outer layer being formed of an elastomeric material having a Shore 00 hardness of between 15 and 80,
wherein the outer layer is spherical and comprises a plurality of protrusions extending radially outwards from an exterior surface of the outer layer, the plurality of protrusions comprising:
a first subset of protrusions distributed across a first half of the outer layer, each protrusion of the first subset of protrusions having a first height; and
a second subset of protrusions distributed across a second half of the outer layer that is opposite to the first half of the outer layer, each protrusion of the second subset of protrusions having a second height higher than the first height, wherein a radius of a notional hemisphere extending across tips of the protrusions of the second subset of protrusions is larger than a radius of a notional hemisphere extending across tips of the protrusions of the first subset of protrusions, and
wherein one or more of the plurality of protrusions are hollow and one or more of the plurality of protrusions are non-hollow; and
a core material located in the cavity and in contact with an inner surface of the outer layer, the core material being a liquid or gel and substantially at atmospheric pressure when at room temperature, the core material being adapted to be one or more of: heated and cooled, wherein the core material at least partially extends into the hollow protrusions,
wherein the breast aid is substantially ball-shaped,
wherein the breast aid is adapted to be manually rolled over a breast,
wherein a modulus of elasticity of the entire breast aid is between 0.5 kPa and 10 kPa, and
wherein a thickness of the outer layer is less than 3 mm.
2 . The breast aid of claim 1 , wherein the plurality of protrusions are integrally formed with the outer layer and are spikes, lumps or bumps or a combination thereof.
3 . The breast aid of claim 2 , wherein the outer layer has substantially the same thickness at areas where hollow protrusions are formed and at areas with no protrusions.
4 . The breast aid of claim 2 , wherein the protrusions have:
a height of at least 1 mm, at least 2 mm or at least 3 mm; and/or
a height of less than 10 mm, less than 8 mm or less than 6 mm.
5 . The breast aid of claim 2 , wherein the difference between the first height and the second height is at least 0.5 mm, at least 1 mm or at least 1.5 mm.
6 . The breast aid of claim 5 , wherein the first and second halves of the outer layer are separately formed and connected together to form the cavity.
7 . The breast aid of claim 1 , wherein the core material is adapted to be heated to at least 50° C.
8 . The breast aid of claim 1 , wherein the core material is adapted to be cooled to 5° C. or below.
9 . The breast aid of claim 1 , wherein the core material is adapted to be at least one of repeatedly heated and repeatedly cooled.
10 . The breast aid of claim 1 , wherein the core material comprises water, a gel, a saline solution or a combination thereof, and/or wherein the core material comprises propylene glycol, calcium chloride, magnesium sulphate, ammonium nitrate or a combination thereof.
11 . The breast aid of claim 1 , wherein a maximum diameter of the breast aid as defined by the outer layer is between about 20 mm and 60 mm, or is between about 45 mm and 55 mm, or is about 50 mm.
12 . The breast aid of claim 1 , wherein the outer layer is formed of silicone, rubber, polyethylene, nylon, a thermoplastic polyamide, phthalate free vinyl chloride or a combination thereof.
13 . The breast aid of claim 1 , wherein the outer layer has a hardness between Shore 00 of between 20 and 65, or between Shore 00 of 20 and Shore A of 20.
14 . A method of aiding lactation, the method comprising:
manually rolling the breast aid according to claim 1 over a breast.
15 . A device comprising:
an outer layer defining a cavity, the outer layer being formed of an elastomeric material having a Shore 00 hardness of between 15 and 80,
wherein the outer layer is spherical and comprises a plurality of protrusions extending radially outwards from an exterior surface of the outer layer, the plurality of protrusions comprising:
a first subset of protrusions distributed across a first half of the outer layer, each protrusion of the first subset of protrusions having a first height; and
a second subset of protrusions distributed across a second half of the outer layer that is opposite to the first half of the outer layer, each protrusion of the second subset of protrusions having a second height higher than the first height, wherein a radius of a notional hemisphere extending across tips of the protrusions of the second subset of protrusions is larger than a radius of a notional hemisphere extending across tips of the protrusions of the first subset of protrusions,
wherein one or more of the plurality of protrusions are hollow and one or more of the plurality of protrusions are non-hollow; and
a core material located in the cavity and in contact with an inner surface of the outer layer, the core material being a liquid or a gel and substantially at atmospheric pressure when at room temperature, the core material being adapted to be one or more of: heated and cooled, wherein the core material at least partially extends not the hollow protrusions,
wherein the device is substantially ball-shaped,
wherein the device is adapted to be manually rolled over body tissue,
wherein a modulus of elasticity of the entire breast aid is between 0.5 kPa and 10 kPa, and
wherein a thickness of the outer layer is less than 3 mm.
