The present invention relates to a breast pump and, more particularly, to a hands-free breast pump that is worn on a mother’s breast to freely conduct breast pumping, without being taken by her hands. According to the present invention, the hands-free breast pump is configured wherein the adsorption unit coming into contact with the mother’s breast and the storage vessel storing the breast milk discharged through the adsorption unit therein are located in the horizontal direction with respect to each other, or the storage vessel is inclined backwardly from the adsorption unit by a given angle, so that the hands-free breast pump is stably fixed to the mother’s breast through the bra in the state of coming into close contact with her breast, thereby freely conducting the breast pumping, without being taken by her hands.一種免手持式擠乳器係穿戴於一母親的乳房，用以自由地進行擠乳作業，而不用藉由她的手扶持。在本發明中，免手持式擠乳器係藉由一吸附單元接觸母親的乳房，且藉由一儲存容器儲存經由吸附單元排出的母乳，儲存容器設置於一垂直方向與吸附單元相互垂直，或是沿一特定的角度自吸附單元向後地傾斜，使得免手持式擠乳器在一與母親的乳房接觸的狀態下，係經由胸罩穩定地固定於母親的乳房，因此，免手持式擠乳器不用藉由她的手扶持而自由地進行擠乳作業。
