The present application is a continuation of U.S. patent application Ser. No. 12/853,644, filed Aug. 10, 2010. The entire disclosure contents of this application are herewith incorporated by reference into the present application.
FIELD OF THE INVENTIONThis invention relates to a device for releasably attaching a milk receiving bag to a breastpump, and to the bag that is connected to the breastpump by the device.
BACKGROUNDBreastmilk pumps are well known and are generally comprised of a hood or shield that fits over a portion or the entire breast, a vacuum pump connected to the hood for generating an intermittent pressure variation within the hood, and a receptacle or container for the expressed milk. The receptacle in such an arrangement is often a rigid plastic feeding bottle well known to those in the art. It is also known to use a plastic bag as the receptacle, sometimes in combination with a rigid outer shell supporting the bag. There are manually driven vacuum pumps (e.g., handheld piston pumps) which most commonly connect at or closely adjacent to the hood, as well as vacuum pumps that are driven by an electric motor and interconnect to the hood via tubing. The vacuum pumps of these devices intermittently generate a pressure, most typically a vacuum (or a negative pressure) within the hood, with the hood encompassing the nipple and a substantial amount of the breast. The intermittent suction action of the pump serves to pull on and/or compress the breast, drawing it within the narrowing funnel of the hood, to thereby express milk in an action reminiscent of suckling. The milk so extracted typically flows from the hood into a container, e.g., a bottle or a bag, for storage and later use. A breastpump of the foregoing type is shown in U.S. Pat. No. 4,857,051.
As noted, plastic bags have been proposed and adapted for use with a breastpump to function in the above-described manner. The method of using and storing these types of bags are well-documented as are the advantages. See for instance, U.S. patent Publication No. 2002/0156419. Where bags are used independently of a bottle, this eliminates the need to then transfer milk from a container (bottle) to a plastic bag for storage. The presence of the bag makes unnecessary the step of cleaning a container after use. Attaching the bag to the pump in a simple and straightforward manner for the mother is something worthy of achieving, however.
SUMMARYThe present invention in one embodiment provides a breastpump having a breast shield with a first end for placement on a breast and a second end for connection to an attachment device. The attachment device in one form is an adaptor having at least one mounting ear (or hook), and uses a milk collection bag having an aperture that connects to the at least one mounting ear. The adaptor attaches to the standard breastpump assembly much the same as a bottle would, e.g., by matching screw threads. The adaptor serves to suspend the bag open at the top directly beneath the conduit structure of the breastpump assembly, through which milk flows, such that the milk flows into the open bag.
The attachment device in a preferred form is an adaptor connectable to the breastpump having mounting ears on opposite sides. In another embodiment, the ears are formed as part of a modified breastpump assembly. A bag having apertures adapted to connect to the mounting ears allows the bag to be easily attached and removed from the adaptor.
In yet another embodiment, a bag for collecting mother's milk is provided including front and back sides, each of the front and back sides having an aperture therein for use in hanging the bag from the attachment device.
In yet another embodiment, a method for attaching a milk bag to a breastpump is disclosed, the method including providing an adaptor having mounting ears, providing a bag having apertures adapted to engage over the mounting ears, first putting one mounting ear through a bag aperture, and then putting the other mounting ear through another bag aperture, and attaching the adaptor to the breastpump assembly (either before or after the bag is mounted), with the bag open beneath a conduit structure through which milk passes.
These and other features and advantages of the present invention will be further understood and appreciated when considered in relation to the following detailed description of embodiments of the invention, taken in conjunction with the drawings, in which:
One embodiment of the invention is shown in an attachment arrangement of
The breastpump assembly 200 may be a manual breastpump, such as the breastpump disclosed in U.S. Pat. No. 7,727,182, the contents of which are also incorporated herein by reference. Alternatively, the attachment arrangement 100 may be used with an electric breastpump, such as U.S. Pat. Nos. 6,547,756 or 6,257,847, each of can be referred to for details of the breastpumping equipment in general. In this embodiment, the breastpump assembly itself is not significant, in that the adaptor 120 is intended to attach to a standard-issue breastpump assembly, e.g., a breastpump assembly that is manufactured for a bottle to be attached thereto;

A resealable or reclosable seal 116 is provided for access to the bag interior when in an open condition, and seals the bag when in a closed condition. In one embodiment, the reclosable seal 116 is preferably a “zip” type closure or an equivalent, formed by attaching to either front sheet 102 or back sheet 104, an extended male element above and essentially parallel to bottom edge 108, the male element being press fit into a corresponding female channel-type element attached to the other of the front and back sheet 102, 104. A number of known designs exist for “male/female” zip-type closures. Some are designed to fasten together to merely place a bag in a closed condition, and some are designed to retain fluids within the bag in a leak-proof fashion. Of course, other mechanisms of sealing the bag are contemplated for use in the present invention to seal the bag in a reclosable fashion. Reclosable seal 116 extends between side edges 110, 112 and is also located below top edge 106. Thereby, when reclosable seal 116 is closed, the combination of reclosable seal 116, sealed side edges 110, 112 and sealed pouch bottom edge 114 define a generally rectangular bag pouch 115 suitable for retaining fluids therewithin.
A portion of each of front sheet 102 and back sheet 104 extends beyond reclosable seal 116, respectively portions 102a and 104a. The bag 101 also includes apertures 118, 119 located on the front and back portions 102a and 104a, respectively. The apertures 118, 119 support the bag 101 on the adaptor 120, which is described in detail below. Although the apertures 118, 119 are shown having a generally oval shape, it should be understood that the apertures may take any suitable shape, including a simple slit.
Bag 101 may further include a label area (not shown) located on the outer side of front sheet 102, of sufficient dimensions to allow for some information to be provided on bag 101 regarding the contents in the bag, such as, for example, “DATE”, “VOLUME” and “NAME”, either by writing directly on front sheet 102, or indirectly by adhering an optional label at this location. Other locations for information may be provided. Calibrated markings (not shown) as for milk volume may additionally be provided.

The adaptor 120 attaches to the breastpump by a connector portion 126. In one embodiment, the connector portion 126 may be a threaded mechanism, match-threaded to a collar 201 of a standard breastpump assembly. However, it should be understood that the connector portion may comprise any suitable mechanism to secure the adaptor 120 to the breastpump assembly, as long as the connector portion 126 and collar 201 have cooperating connection mechanisms. The cooperating portions releasably mechanically connect the adaptor 120 to the collar 201 in any suitable manner as long as a portion of the adaptor communicates with a milk outlet of the breastpump assembly.
Referring now to
In operation, the adaptor 120 is placed on the collar 201 of the breastpump assembly 200. A user first places one mounting ear through a bag aperture, then places the other mounting ear through the other bag aperture. The bag 101 is then securely attached to the breastpump assembly opened and suspended beneath the conduit structure and outlet 208 to collect milk during a pumping session.
Alternatively, the bag 101 could first be attached to the adaptor 120, and then the mounted bag is positioned on the breastpump assembly 200 by attaching the adaptor 120 thereto.
In another embodiment, shown in
Thus, while the invention has been described herein with relation to certain embodiments and applications, those with skill in this art will recognize changes, modifications, alterations and the like which still come within the spirit of the inventive concept, and such are intended to be included within the scope of the invention as expressed in the following claims. For instance, while the bag has been described with a particular aperture, other ways to yield an opening in the upper part of the bag are known in the art, such as slits, an area of perforations which can then be breached, a thinned portion which can be punctured, and so on. In a similar vein, while the bag has been described as being hung from ears or hooks, other elements could fulfill the same function, such as buttons, pins, posts, and so forth.
Further, in an alternate embodiment, the adaptor 120 may comprise clips or pins, for example, which attach to a standard milk collection bag. In this embodiment, the milk collection bag would not have apertures or any corresponding mounting features.
