Definitions

  • This invention relates to breast pumps.
  • a breast pump having a funnel with a convergent bell- portion for placing on the breast over the nipple, wherein a tubular outlet of the funnel leading from the bell-portion is angled out of axial alignment with said bell-portion, and is coupled via a tubular inlet to a source of suction for drawing off expressed milk from the funnel, and wherein the outlet is axially aligned with the inlet and is selectively adjustable angularly relative to the inlet about their mutually aligned axes for varying the orientation of the funnel with respect to said source.
  • the breast pump according to the invention has the advantage that the funnel can be adjusted to take up a variety of orientations to suit the woman concerned in finding a comfortable position for holding and operating the pump.
  • the angle of axial misalignment between the tubular outlet and the bell- portion may conveniently be within the range 20 to 40 degrees, and may be specifically substantially 30 degrees.
  • the tubular outlet of the breast pump according to the invention may extend coaxially within the tubular inlet and may be a selectively-releasable fit therein to facilitate cleaning.
  • the source of suction may be a hand-operated diaphragm pump, and for convenience in disassembly of the breast pump for cleaning the hand-lever of the pump may be intercoupled with the pump-diaphragm such that the diaphragm is withdrawn as one with the hand-lever when the hand-lever is detached from the body of the pump.
  • Figures 1 to 3 are, respectively, a side elevation, a plan and a rear elevation of the breast pump according to the invention
  • Figure 4 is a sectional perspective view of the breast pump with the collection bottle of the pump omitted;
  • Figure 5 is a sectional side elevation of the breast pump, the section being taken on the line V-V of Figure 3;
  • Figure 6 to 9 are, respectively, illustrative of details of features of the breast pump to enlarged scale
  • Figure 10 is a perspective view of the breast pump showing part of it in exploded form.
  • Figures 11 to 13 are illustrative of successive stages during manufacture of part of the breast pump.
  • the breast pump has a plastics body 1 that screws onto a bottle 2 for collecting expressed milk, and a pivoted lever 3 for pumping the milk from the breast for collection. More particularly, a funnel 4 for placing on the breast over the nipple, is coupled by its output spigot-tube 5 into a tubular socket 6 of the body 1, and operation of the lever 3 creates suction that draws the milk into the body
  • the funnel 4 can be adjusted selectively to take up a variety of different orientations with respect to the body 1 to suit the woman concerned in finding a comfortable position for holding and operating the pump.
  • a stand 8 is provided for convenient retention of the assembled breast pump when it is not being used for the expression of milk.
  • the bottle 2 fits snugly into the stand 8 so that the whole assembly of pump is held securely upright.
  • the funnel 4 has a silicone rubber insert 10 to provide cushioning for the breast received in the bell-portion 7.
  • the bell-portion 7 is dimpled externally so as form raised elements 11 on its inside surface that serve to space the insert 10 away from that surface and thereby enhance the cushioning effect and comfort during pump operation.
  • a one-way valve 18 located in the bottom of the chamber 17 for opening into the bottle 2, closes in response to the pressure drop created by the lifting of the diaphragm 12. This leaves the chamber 17 open only to the interior of the funnel 4 via the tube 5 and socket 6, so that milk is thereby expressed and drawn into the chamber 17.
  • the one-way valve 18 opens to allow the milk to pass into the bottle 2.
  • the outlet- side of the valve 18 is surrounded by an annular skirt 19 for directing the milk into the bottle 2 without undue splashing, and displaced air can leave the bottle 2 via interruptions in the screw-thread 20 of the body 1 ( Figure 4) .
  • the tube 5 can be withdrawn from the socket 6 simply by pulling.
  • the rotational joint between the tube 5 and the socket 6 is effected by a resilient-plastics ring 21 that engages within a circumferential groove 22 of the tube 5.
  • the ring 21 is chamfered so that with its generally wedge-section configuration it resists withdrawal of the tube 5 from the socket 6 more strongly than it resists its insertion, and moreover provides an air and liquid seal between the tube 5 and the socket 6.
  • the lever 3 is retained as one with the diaphragm 12, so that lifting it and unclipping the hinge 13 to remove the lever 3 from the body 1, also removes the diaphragm 12. This facilitates cleaning and simplifies re-assembly of the pump by avoiding the necessity for intercoupling the lever 3 and diaphragm 12.
  • the intercoupling is carried out in manufacture as illustrated in Figures 11 to 13.
  • a narrow slot 23 in the bowl- portion 14 of the lever 3 extends part-way round the portion 14 from an aperture 24, and the lever 3 is v presented to the diaphragm 12 as illustrated, to enter the knob-part 15 into the aperture 24.
  • the lever 3 is then swung down as illustrated in Figure 12, engaging and trapping the knob-part 15 within the slot 23 so as thereby to intercouple the diaphragm 12 with the lever 3.
  • a plug 25 is now entered and sealed in the aperture 24 as illustrated in Figure 13, so that the knob-part 15 cannot be disengaged from the slot 23 and the lever 3 and diaphragm 12 remain as one.

Abstract

L'invention concerne la sortie (5) de l'entonnoir (4) de collecte de lait d'une pompe tire-lait. Ladite sortie est inclinée par rapport à l'alignement axial avec la cloche (7) tire-lait de l'entonnoir (4), tourne de manière coaxiale à l'intérieur d'une douille (6) d'entrée dans le corps (1) de la pompe, ce qui permet de régler l'orientation de l'entonnoir par rapport au corps (1) de la pompe aux fins du confort de l'utilisateur. La sortie (5) de l'entonnoir est retenue amovible à l'intérieur de la douille (6), une bague chanfreinée (21) assurant l'étanchéité à l'air et au liquide et un levier (3) manuel de la pompe étant articulé au corps (1) de manière amovible. Le diaphragme (12) de pompe est retenu relié au levier (3), ce qui permet de les retirer ensemble lorsque l'on décroche le levier (3) de son articulation (13) en vue de le nettoyer.
