The invention relates to a physiological pad structure, in particular to a physiological pad structure which can be automatically retracted.It is composed of a cotton body.And the cotton body has an inner surface layer corresponding to the human body and an outer surface layer different from the human body.The feature of this creation is that there is a retractable elastic part on both sides of the cotton body.And each of the retracting elastic parts is arranged in the way of generating the retracting force to the inner surface layer.In this way,The cotton body can produce inward rolling force.Enhance its fit to the human body.Further improve its leak proof effect,At the time of cleaning,The utility model can reduce the trouble of rolling up and clearing the physiological pad with bare hands.It can also avoid the exposure of menstrual blood after the use of physiological pads.It can reduce the generation of peculiar smell.It can promote environmental health.So as to improve its practicability.本創作涉及一種生理護墊結構，特別係指一種可自動捲收之生理護墊結構，其係由一棉質本體所構成，又該棉質本體具有一對應人體之內表層及一異於人體之外表層，本創作之特色在於該棉質本體於兩側緣上分設有一捲收彈件，且各該捲收彈件係以向內表層產生捲收預力之方式設置，藉此，讓棉質本體可產生向內之捲收預力，有效提升其相對人體的貼合性，進一步增進其防漏效果，於清理時，則可減少徒手捲收清理生理護墊的困擾，更可避免生理護墊使用後的經血暴露在外，而能減少異味的產生，且可促進環境衛生，從而提高其實用性。
