Physiological simulator integral of shield for breast pump

Abstract

The combination of a breast pump shield, with its ring, applied to the flange lower end of the shield, and the ring being C shaped in cross-section, having an upper flange, a lower flange, both integrally structured with a base wall. The physiological stimulator integrally formed with the lower flange of the sealing ring extends inwardly and upwardly within the shield, and therein functions as a means to place pressure upon the breast of the mother to help induce and stimulate the flow of breast milk during usage of the associated breast pump.

DESCRIPTION OF THE PREFERRED EMBODIMENT

(9) In referring to the drawings, and in particular FIG. 1, therein is shown the combination of the breast shield 1 generally formed with a conical section 2 and having an integral flange 3 at its bottom, and a funnel like portion 4 at its upper end, which accommodates the fastening of the tubing from the breast pump, as at tube T, thereon, during preparation for usage of the device. Shown separately, downwardly therefrom, is the sealing ring 5 and which includes a C-section like interior channel or annulus 10, having an integral upper flange 7 and an integral lower flange 6 and which are secured together by means of a base member 9 with the interior channel or annulus 10 and the ring facing inwardly, about the annulus forming the ring 5.

(10) Connecting to the lower flange 6 is the physiological stimulator 11 of the invention. It connects with or is integrally formed extending inwardly from the inner lower edge of the ring 5, as at 12, and then further extends inwardly and upwardly as at an upwardly extending portion 13 so that when the flange 3 of the shield locates within the interior channel or annulus 10 of the C-shaped interior channel or annulus 10, the stimulator rests against the interior surface, as at 14, of the shield, extending approximately halfway up the interior of the shield, and for the following purposes.

(11) Essentially, the stimulator 11 is designed to emulate the action of the tongue of the infant, as it impresses upon the surface of the mother's breast, and to help stimulate the discharge of the mother's milk, during a feeding cycle. But, obviously, during the usage of a breast pump, there is no infant tongue available for that purpose. Hence, the stimulator 11, and in particular its upwardly extending portion 13, resting against the interior of the shield 1, is designed to press upon the surface of the breast, and to act as a stimulator for inducing the discharge of the mother's milk, even during the application of a breast pump, for mother's milk collection purposes. Optimally, the proximal aspect of the physiological stimulator is thicker than the distal aspect, to provide the automatic and physiological peristaltic action during the negative pressure application, without using any extra parts. Hence, and what is more unique about the usage of this artificial type of stimulator, is that the ring, or the shield, can be pivoted, even approximately 360 degrees in its location, to act as a stimulator upon all surfaces of the breast, during usage of this development, in combination with the breast pump, to induce the flow of mother's milk, for collection. It is already known in the art that these breast pumps are readily available for usage, and the pump that is attached into the shield, and through the tube T by the breast pump, is usually transferred to a bag, for collection, and for later usage and application in the feeding of the infant.

(12) The shield, its ring, and its stimulator 11, may be made of any soft type of polymer, such as an acrylic resin, for transparent purposes, and of a silicone polymer, which is a polymerized organic siloxanes, which has a soft texture, and therefore, its ring can properly seal against the body of the mother, in order to make the breast pump operate more efficiently and effectively, and furthermore, its stimulator 11 has a soft texture, so that it can feel more like the tongue of the infant, and not be abrasive or cause any inflammation to the breast, during prolonged usage.

(13) FIG. 2 shows the combination of the shield 1, with its applied ring 5 wherein the flange 3 of the shield fits within the interior channel or annulus 10 of the ring, when the two are combined together in preparation for usage. And, it shows the application of the stimulator 11 resting in proximity or continuously with the inner surface of the conical section 2 of the shield, in preparation for its usage, and in the location where it will press against the breast of the mother, during application of the breast pump.

(14) FIG. 3 shows just the ring 5, its upper flange 7, its lower flange 6 and its outer base member 9, all integrally formed together, and its interior channel or annulus 10 that cooperates for holding the flange 3 of the shield into position, during usage. Obviously, for cleaning purposes, the shield 1 can be easily extracted from the interior of the flexible ring 5, after completion of a breast pump cycle of usage. In addition, the stimulator 11 can be seen, extending integrally from the lower flange 6, as at 12, and then extending upwardly, as at an upwardly extending portion 13, to function for the purposes of stimulating the production of the mother's milk, during usage of the breast pump.

(15) The physiological stimulator 11 does extend up some distance within the associated shield, approximately halfway up the interior of the associated shield, more or less, when installed with the ring for connection to the breast pump. Furthermore, the width of the stimulator, in order to simulate the infant's tongue, may extend for approximately some degrees, along the sector of the circumference of the sealing ring, perhaps in the vicinity of 2-20 degrees, more or less, in width. In the extension of the stimulator within the shield, it has been found that an extension of approximately ½-1½ inches in length, have worked satisfactorily. Furthermore, the width of the stimulator may be wider, where it connects with the lower flange of the sealing ring, than at its upper extension, that locates within the shield of the pump. As an alternative, it is possible that the stimulator could be molded upon the inner surface of the shield, approximately at the location as can be seen in FIG. 2, and therein acts as a means for enhancing the flow of mother's milk, during usage.

(16) FIG. 4 provides a clearer sectional view of the ring 5, its various components such as the upper flange 7, the lower flange 6, and the base member 9 integrally formed between the two. And, the inner channel or annulus 10 that accommodates the location of the shield flange 3, can be seen. More specifically, the stimulator 11 as integrally formed with the lower flange 6, as at that juncture 12, is clearly noted. And, the upward portion of the stimulator, as at an upwardly extending portion 13, that extends upwardly and locates contiguously with the inner surface of the shield 1, can now be quite clearly seen.

(17) FIG. 5 shows an isometric view of the combined shield 1 and its associated ring 5. Also, can be seen is the upper portion of the shield, as the port 4, integral of the said shield, that connects with the tubing of the breast pump.

(18) FIG. 6 discloses a cross-section of the shield 1, and how the stimulator 11 rests against the interior of the shield, during application when extracting breast milk from the mother. Actually, this stimulator may be formed upon the inner surface of the shield to function for the purposes of this invention.

(19) FIG. 7 provides an overall schematic view of the entire structure, including the existing pump shield 1, the application of its lower integral flange 3 within the inner channel or annulus 10 of the ring 5, and how it is placed upon the mother's breast B during its application.

(20) Thus, it is believed that one can now fully understand and comprehend the structure of this particular shield, and its associated ring with the physiological stimulator formed thereon, in order to function as a means for enhancing the delivery and flow of breast milk from the mother, during its usage and application.
