A breast shield for expressing human breast milk. The breast shield includes an outer housing and a flexible inner liner within the outer housing. In use, with the breast shield applied to a breast, the inner liner is in contact with the surface of both the areola and nipple of the breast. The breast shield further includes an outer chamber between the outer housing and the inner liner and an inner chamber within the inner liner. In use, the inner and outer chambers, are subjectable to differential pressure and the differential pressure is operable to cause the inner liner to exert a massaging effect against the surface of both the areola and nipple of a breast.

The present application belongs to the technical field of breast milk biological monitoring, and particularly relates to a method for detecting chemical contaminants in breast milk based on PPAR gamma nuclear receptor affinity selection mass spectrometry, which is used for non-target identification of chemical contaminants in human breast milk, and further evaluates potential PPAR gamma ligands through molecular docking and surface plasmon resonance (SPR). The above detection method links chemical detection directly with receptor-mediated activity, promotes breast milk biological monitoring, makes up for the key knowledge gap of evaluating lactation exposure risk, and provides a basis for discovery and identification of novel contaminants in human breast milk biological monitoring.
