Abstract: A breastpump for expressing human breastmilk comprises a housing, a pump chamber with a driven pump membrane for producing a vacuum, and a breast shield with an interior for receiving a mother's breast. Expressed milk flows from the interior into the pump chamber through a milk channel, said pump chamber having an outlet opening through which expressed milk flows from the pump chamber into a milk collection container. The breastpump comprises a multipart hygiene module comprising a first part with a flow opening for connecting to the interior, a valve body with at least one valve and a second part with a rigid cup for forming the pump chamber. The valve body is arranged between the first and second part and the hygiene module as a whole is connectable to the housing of the breastpump in a sealing and detachable manner.

Abstract: A breast shield for a breast pump for expressing human breast milk comprises a rigid base part (1) with a tubular connection piece (10) and with a funnel (11), which is integrally moulded in one piece thereon and widens away from the connection piece (10), for receiving a breast. The breast shield additionally comprises a flexible collar (2) which is arranged on the funnel (11) at an end of the funnel (11) remote from the connection piece (10) and which is realized to be placed onto the mother's breast. The named end of the funnel (11) forms a first contact surface (12) and an end of the collar (2) which faces the funnel (11) forms a second contact surface (22) and they both adjoin one another in an obtuse manner in a circumferential connecting joint (4), wherein the connecting joint is a butt joint.

Abstract: A breast shield for a breast pump for pumping human breast milk, comprising a rigid base part having a tubular connecting piece and a funnel that is integrally formed therewith and that expands away from the connecting piece for accommodating a mother's breast. The breast shield includes a flexible collar, which is arranged on the funnel at the end of the funnel facing away from the connection piece, and which is designed to be placed on the mother's breast. The end of the funnel forms a first contact surface, and an end of the collar facing the funnel forms a second contact surface (22), which in a circumferential connecting seam adjoin each other in a blunt way. The funnel has a first wall thickness and the collar has a second wall thickness, wherein said second wall thickness is approximately equal to the first wall thickness. The breast shield can be produced simply and inexpensively, nevertheless allowing a high degree of wearing comfort and a tight fit on the mother's breast.

Abstract: A breast shield for a breast pump for expressing human breast milk, comprising a funnel for applying to the human mother's breast and a connection part, wherein the funnel widens in the direction of the mother's breast and encloses at least one nipple and one areola surrounding the nipple of the mother's breast. The funnel comprises an end near to the breast, which forms a contact edge for contacting the mother's breast. The breast shield has a through-opening which extends from the end of the funnel near the breast up to the end of the connection part further from the breast, and which serves to apply a negative pressure to the mother's breast and to discharge expressed breast milk. The contact edge of the funnel is formed by a space curve that is not positioned in one plane, wherein the funnel has at least two planes of symmetry. The breast shield permits an application on the mother's breast that is optimally sealing and comfortable for the mother.

Abstract: A device for expressing human breast milk has a breast shield for bearing against a mother's breast, a vacuum pump for generating a vacuum, a line which connects the vacuum pump to the breast shield and is intended for transmitting the vacuum generated to the breast shield, and a chamber. The line ends on the pump side in a first port of the chamber. The chamber has a second port for connection to a milk collecting container. The two ports in the chamber are connected to each other in terms of fluid communication. During the expressing operation, the line forms a milk line for transporting breast milk expressed in the breast shield to the chamber and from the chamber to the milk collecting container. The pump can be designed to be quiet and small.

Abstract: A breastshield unit for use with a breastpump for expressing human breastmilk using underpressure has a dimensionally stable breastshield and a flexible breastshield insert for placing in the breastshield. The breastshield has a first, open breastshield end for placing on a mother's breast. The breastshield insert has a first insert end and a second insert end which define a longitudinal direction, the first, open breastshield end having a peripheral edge on which the breastshield insert is securable with the first insert end. In the assembled state, the breastshield insert extends from this first insert end through the inside of the breastshield to the second insert end, wherein the breastshield insert, between the first and second insert ends, extends substantially spaced apart from the breastshield. In the assembled state of the breastshield insert, the second insert end is displaceable in the longitudinal direction relative to the breastshield.

Abstract: A breastshield unit for use with a breastpump for expressing human breastmilk has a breastshield for receiving a mother's breast and a media separation device for transferring a vacuum into the interior of the breastshield. The breastshield has a receiving area for receiving a nipple of the mother's breast. The media separation device has a media separation membrane which, for the purpose of transferring the vacuum, is movable to and fro between two positions. The media separation membrane is located in the receiving area at least in one of the two positions. Despite the integrated media separation, the breastshield unit can be made extremely compact and minimizes the dead volume.

Abstract: Expandable fixation assemblies, expandable cranial fixation assemblies, and expandable intervertebral implant assemblies are provided for securing structures to bone and for securing bones and/or bone segments with respect to each other. An expansion member can be moved through at least a portion of an expandable fixation body, thereby causing expansion of the expandable fixation body, such that bone engagement features of the expandable fixation body engage surrounding structure, such as bone.

Abstract: Described herein is a surgical nail in the form of an intramedullary nail with a central axis made from a material M with a tensile strength Fz, compressive strength Fd, density ?2 and modulus of elasticity E. The nail has a transverse bore extending transversely to the central axis and having a cross-sectional profile F and a transverse axis, the cross-sectional profile F having a maximum length a that runs in the direction of the central axis and a maximum width b that runs perpendicular to the length. An insert with the longitudinal axis, made from material m and having a modulus of elasticity e that is smaller than the modulus of elasticity E of material M, can be introduced into the transverse bore. The insert also has a length L that runs in the direction of its longitudinal axis and satisfies the condition L>0.2 D.
