Embodiment Construction

[0068] figure 1 The illustrated breast pump device 100, in particular its pump body 130, has an uncontrollable shape and size.

[0069] The breast pump device 1 according to an embodiment of the invention, more precisely its pump body 130, further comprises actuator elements 200, 300, 400 capable of deforming when a control signal is applied thereto, reference will be made below to Figure 4 This is discussed to Figure 7. Deformation of the actuator element modifies the shape and size of the pump volume of the pump body 130 and allows adaptation to the needs of a particular user.

[0070] In the following, the actuator elements 200, 300, 400 comprise electroactive materials (EAM), in particular electroactive polymers (EAP). Electroactive materials (EAMs) are a class of materials within the field of electrically responsive materials. When implemented in an actuation device, subjecting the EAMs to electrical drive signals may cause them to change size and / or shape. This effe...

Abstract

Based on the field of breastfeeding, a breast pump device (100) for expressing breast milk is disclosed. The breast pump device (100) includes: a container unit (110) for containing expressed breast milk; and a pump unit (120) including a pump body (130) and a pump unit (130) for feeding a pump body (130) A pumping device (140) that applies negative pressure to the pump volume. The pump body (130) includes an inlet portion (132) adapted to be received on a female breast and an outlet portion (134) adapted to guide the expressed milk to the container unit (110). The pump body (130) includes an actuator element (200, 300, 400) including an active material capable of deforming when a control signal is applied to the actuator element, wherein the actuation Deformation of the device element modifies at least one of the shape and size of the pump volume.

Description

technical field [0001] The present invention relates to the field of breastfeeding and in particular to breast pump devices. The present invention particularly relates to such a breast pump device having a deformable actuator element comprising an electroactive material (EAM). Background technique [0002] Breast pumps for expressing milk from the breasts of lactating women are known. exist figure 1 An example of a known breast pump is illustrated in . The breast pump device 100 includes a pump unit 120 including a pump body 130 and a pumping device 140 . The pump body 130 defines a pump volume outside of which the pumping device 140 draws air in order to apply a negative pressure to simulate the sucking of an infant during breastfeeding. In this example, the pumping device 140 includes an electric pumping device that is partially positioned separate from the pump body 130 for ease of handling. [0003] In operation, the inlet portion 132 is received on the female breas...
