An apparatus structured to contact external tissue, such as skin, of a user includes an elastomeric contacting portion that is structured to directly engage the external tissue. The contacting portion has an engineered surface (64A, 64B) that includes a plurality of non-random, predesigned surface features (70, 74B, 76B, 78B) designed to reduce friction and improve user comfort. In one implementation, the pitch (P) between each immediately adjacent pair of the surface features (70, 76B) is less than or equal to a predetermined maximum pitch value, and the height (H) of each of the surface features (70, 76B) is less than or equal to a predetermined maximum height value.

A surgical irrigation and suction apparatus includes a housing forming a handle and a barrel. The housing contains a suction tube for disposing of waste slurry and am irrigation tube for provision of irrigation fluid. The apparatus further includes a removable tube divided into an irrigation chamber and a suction chamber. The two chambers are collinearly arranged with respect to each other. The removable tube is coupled with the housing via a tube fitting. The apparatus further includes an inlet/outlet tip coupled with the other end of the removable tube, the tip including an outlet port and a plurality of inlet ports, respectively. The irrigation chamber terminates distal to the barrel with the tip arranged to spray the irrigation fluid through the outlet port. The suction chamber terminates distal to the barrel with the tip for recovery of the waste slurry through the plurality of inlet ports.

An improved accessory light for breast pumps apparatus is described. This improved accessory light for breast pumps apparatus may be secured or affixed to various models of breast pumps to allow the user to have a hands-free, illuminated view of the milk being expressed from the breast. The accessory light may consist of a clamp-based accessory secured to a breast shield neck or an accessory that is secured to the breast shield back using a flexible material.

Embodiments of a breast feeding apparatus include a breast pump end configured for connection to a breast pump; a nipple end configured for connection to a nipple; a first sized reservoir and a second sized reservoir having a size different from that of the first sized reservoir located between the breast pump end and the nipple end; tubing connecting the breast pump end to the first sized and second different sized reservoirs, and nipple end to one another in series; and a plurality of air release valves located along the tubing. A method of using the breast feeding apparatus includes connecting the breast pump end of the apparatus to a breast pump, activating the breast pump to pump breast milk into the tubing and reservoirs of the apparatus, and releasing air through one or more of the air release valves. The air release may be manual or automatic.

A biomechanical breast pump mechanism (1) for expressing breastmilk comprising a biomimetic funnel (2), at least two active actuation areas (23,24) on the funnel (2) and stationary areas (25), the active actuation areas (23,24) being actuatable by a driving mechanism or mechanisms (3) and being configured to replicate the complex functions of the infant's tongue during suckling namely the physical stimulation of the areola (17)/nipple (16); nipple positioning; creating and maintaining low-level baseline vacuum to create air-seal on the breast; generating sub-atmospheric pressure inside the funnel (2); creating and maintaining close-to-zero-air environment in the funnel (2); and control of the vacuum oscillation within predefined ranges coordinated negative and positive actuation (41,42) of one or both actuation areas (23,24) independently or simultaneously.

The present disclosure provides a milk bowl for a breast pump and the breast pump, aiming to solve the problems that components of a breast pump in the prior art are relatively scattered and the breast pump occupies a relatively large space. The milk bowl includes a bowl body, a milk storage cavity and a tee joint are disposed in the bowl body, a milk outlet is provided at a front end of the milk storage cavity, and the tee joint is located in the milk storage cavity; three ports of the tee joint are a milk pumping port, a milk flowing port and a negative pressure port respectively, the negative pressure port of the tee joint and the bowl body are integrated, and the negative pressure port of the tee joint is in communication with the outside. The breast pump includes the above milk bowl for a breast pump and a main unit; the main unit includes a shell; the main unit is disposed in a space formed by a rear side of a semicircular mounting plate and an upper side of an upper panel of the bowl body, and the shell of the main unit and the bowl body together form a hemispherical surface. The tee joint and the bowl body are integrated, thus saving space, reducing a volume, achieving a high degree of integration, and implementing a simple, efficient and low-cost solution for a concealed breast pump.

An example breast pump system can include: a control unit including a processor and memory, the control unit including an interface to control the breast pump system; a vacuum unit controlled by the control unit, the vacuum unit including pump motors to create suction for pumping milk; a support mechanism located remotely from the control unit; and a member extending between the control unit and the support mechanism, the member being movable to allow the control unit to be repositioned relative to the support mechanism. The memory encodes instructions which, when executed by the processor, cause the breast pump system to: select at least a first pump motor from the plurality of pump motors for a first pumping timeframe; and select at least a second pump motor from the plurality of pump motors for a second pumping timeframe.
