When in use, the dustproof cover 17 arranged on the breast shield 111 of the external extrusion component 1 is taken down, a nipple is placed in the nipple placing cavity 213 through the nipple fixing ring 212, the nipple fixing ring 212 is placed at the root of the nipple, and at the moment, the nipple fixing ring 212 is tightly contacted with the root of the nipple but does not cause pressure, so that the nipple is tightly attached and fixed with the internal collection component 2; when the nipple fixing ring 212 and the nipple sleeve 211 are separated from the nipple, the nipple fixing ring 212 is not stretched any more and is naturally tightened to be closed.
When in use, the front cavity 12 is firstly taken down from the milk sucking main body 11, and the inner collecting component 2 is installed in the outer extruding component 1; after the nipple and the surrounding areola of the user are disinfected, the inner collecting component 2 is attached to the nipple of the user, and the outer squeezing component 1 is attached to the breast of the user; the breast pump main unit 15 pumps the air in the breast pump main body 11 through the air flow conduit 14 and produces negative pressure, so that the breast forms lactation under the extrusion and traction actions, and the milk enters the internal collection assembly 2 attached to the breast pump main unit; after the collection is completed, the breast pump main unit 15 is closed, the front cavity 12 is taken off from the breast pump main body 11, and the internal collection assembly 2 is taken out.
Because the inner collecting assembly 2 is tightly attached to the nipple of the user, air between the inner collecting assembly 2 and the outer squeezing assembly 1 cannot enter the inner collecting assembly 2, and separation between the milk pipeline and the air pipeline is achieved in the embodiment, so that pollution of environmental microorganisms to milk samples is avoided.
Meanwhile, the external extrusion component 1 does not need sterilization and is not contacted with milk, and can realize continuous sampling for a plurality of times only by replacing the internal collection component 2, repeated sterilization or replacement of a sampling device is not needed, so that the sampling time is shortened, the sampling efficiency is improved, and the sampling cost is reduced.
In addition, the surface area of the inner collection assembly 2 is much smaller than that of a breast shield, and the residual amount of milk is significantly reduced, greatly reducing waste due to the residual amount, as compared to prior art breast pumps.
Considering the effect of the air flow conduit 14 and the milk flow conduit 22, both should possess a certain toughness.
In addition to the above-described breast milk sampling apparatus, the present invention also provides a sampling method applied to the breast milk sampling apparatus disclosed in the above-described embodiment, the sampling method comprising:
