Her-r011, Evansville, Ind., assignors to Mead .lohnson 8; Company Filed Apr. 3, 1961, Ser. No. 100,169 15 Claims. (Cl. 141-336) This invention relates to a nurser, more specifically a disposable nurser, and to filling apparatus therefor.
Disposable or throwaway nursers have several advantages over more conventional reusable glass or plastic nursing bottles. The elimination of the cost of washing, sterilizing and handling, and of replacement is obvious. Furthermore, empty nursers may be supplied to a hospital in a. sterile condition, and with proper filling apparatus and techniques complete sterility may be maintained prior to feeding. With conventional nursing equipment, there is an ever present danger of contamination, principally through handling of nipples during and following filling. This is a particularly serious problem in hospitals where a large number of nursers are required and often must be handled several times before feeding. In the home, the use of throw-away nursers eliminates the laborious and time consuming operation of washing and sterilizing bottles, nipples and associated apparatus.
A principal object of this invention is to provide an improved throw-away nurser, and a filling apparatus and method providing for easy, accurate filling of nursers in a sterile manner.
I A further feature is the provision of a nursing apparatus including a nurser having a nipple, a supply of nursing formula, and connector means connected with the supply and having a portion insertable through the nipple to fill the nurser. The connector is preferably sealed with a nurser so that a gravity fiow of formula into the nurser automatically stops when the nurser is substantially filled.
Yet another feature is the provision of a filling apparatus for an expandable nurser having a supporting surface portion, a support having a surface receiving said supporting portion of the nurser, the support being relieved to receive the expanded nurser. Still a further feature is that the support has an open side for ease in removal of the nurser therefrom. And another feature is that the support has a plurality of juxtaposed supporting positions of graduated size, for use with varying size of nurser.
A further feature of the invention is the provision of a bulk filling apparatus including a stand having a plurality of supports for bulk formula containers, a plurality of nurser receiving positions operably related with said supports and transfer apparatus connecting bulk containers on the supports with nursers at said receiving positions. Another feature is that provision is made for the reception of at least one more nurser than the number of bulk containers. This permits the use of two nurser receiving positions for a filling operation from one bulk container, with an erntpy nurser always in readiness, while the connecting means for the other bulk containers are connected with the empty nursers, maintaining complete sterility.
Still another feature of the invention is the provision of a method for filling an expandable nurser which comprises providing a supply of nursing formula, making a sealed connection between the supply and the nurser, elevating the supply above the nurser, causing a flow of 3,Zll,860 Patented Aug. 17, 1965 nursing solution, and breaking the sealed connection upon cessation of the flow. A further feature is the step of maintaining idle connectors in sterile condition during the active use of another connector.
Yet a further feature is the provision of a small quantity or home-filling apparatus including a funnel having a cannula insertable through the nipple cover of the nurser and through the nipple into the nurser, with a sleeve surrounding the cannula and engaging the nipple cover, supporting the funnel on the nurser.
Further features and advantages of the invention will be readily apparent from the following specification and the drawings in which:

The throw-away nurser illustrated herein is basically that disclosed and claimed in Dailey et al. application Serial No. 814,110, filed May 18, 1959, and assigned to the assignee of this application. There are certain differences which will be pointed out below.
Briefly, the nurser 20 (FIGURE 5) has top and bottom sections 21 and 22, respectively, both of a plastic material and sealed together at a peripheral seam 23. The two sections have a configuration of a portion of a sphere less than a hemisphere, and the bottom section 22 is of a material which is more flexible than the top section 21, and may be collapsed into the top section, conforming closely with is as shown in the aforementioned Dailey et al. application. The nurser is supplied with the bottom in the collapsed position; and it may be filled shortly prior to use, the bottom expanding to the position shown in FIGURE 5 upon filling. A nipple 24 is secured in an opening in top section 21 and is provided with a nipple cover 2d. A variety of sizes of nursers, as with capacities of two, three and eight ounces, may be provided for feeding differing quantities of formula.
In a hospital nursery or other institutions where a large quantity of nursers must be prepared at one time, it is desirable to utilize a bulk filling apparatus. A preferred at which point the flow stops.
embodiment of bulk filling apparatus is shown in FIG- URES 1-3. The filling stand indicated generally at 23 includes a base 29 and a pair of upright members 3t) carrying between them an elevated platform or shelf 31. Three recesses 32 are provided in the platform 31 to receive and support bulk formula containers 33, 34 and 35. The base 29 is provided with a plurality of recessed portions 37, 38, 39, 4t) and 41 for receiving the nursers during filling. Each of the bulk containers has affixed thereto'a filling set 43, through which formula is caused to flow to the nursers carried on base 29. It has been found that a bulk filling operation is most efficient carried on with three supply containers of formula as there are three principal formula preparations used in a hospital nursery. Newborn infants are first given a special prelacteal formula, following which they are switched to a standard hospital formula. In addition, special formulations are often required because of allergic problems.
Briefly, the connecting means 43 may be sealingly connected with one of the nursers and the formula caused to flow by gravity from the bulk container to the nurser. As the flow continues, the lower portion of the nurser expands, 'until the'nurser'is substantially completely filled The attendant may then shut oh? the connection between the bulk container and the nurser, as by a tubing clamp 45 mounted on a shelf 31, and disconnect the filling set from the nurser. The operation may be repeated with the same or one of the other formulas.
- The nurser illustrated in this application differs from that of the aforementioned Dailey et al. application primarily in the arrangement of the nipple and nipple cover. This is shown in detail in FIGURES 6 and 8. The nipple 24 isprovided with an annular groove 47 in which a folded edge 48 of the top nurser section 21, surrounding the nip ple receiving opening, is received. A groove 4? is formed in the top body section 21 adjacent the base portion 24a of the nipple, further locking the nipple in place on the nurser body. Cover 25 has an inwardly formed rib 5'6 which seats in groove 49 and which has an outwardly opening groove 51 associated therewith on the outer surface of the cover. Rib is seated in groove 49 of the nurser body and secures the cover on the nurser. Furthermore, a sheet 52, which may be of heavy paper, has an annular opening therein within which the cover is received, the sheet being seated in groove 51, keeping cover 25 locked in place. Sheet 52 may have indicia imprinted thereon and serve as a label for the nurser.
The outer end 24b of nipple 24 fits fairly tightly within a cylindrical portion 25a of nipple cover 25, and is supported and positioned therein. The end of nipple 2 is provided with a suitable opening as formed by a pair of crosscuts 54 and 55 (FIGURE 9). A hole 56 is formed in the end surface of cover 25 aligned with and immediately adjacent the nipple opening. A cap 57 (FIGURE 8) is fitted over the cylindrical portion of nipple cover 25, closing the hole 56. Cap 57 is provided with a tab 57a to facilitate removal and to prevent the cap from rolling when removed and laid on its side on a surface.
The connector or filling set 43; is shown in detail in FIGURE 4. The bulk container or can 33 has a generally planar end member 60 which is suitably punctured, as will appear, to receive a fitting 61 which carries an elongated tube 62 which reaches substantially to the opposite end of the can. A length of flexible tubing 63 is connected with tube 62 and has aifixed to its opposite end a suitable connector 64 for communication with a nurser 2i Connector 64 has a pointed spike or cannula portion 65 which may be inserted through the hole 56 in nipple cover 25 and through the crosscut opening in the end of the nipple, as shown in FIGURE 6. A depending skirt 6:? surrounds a portion of cannula 65, and when connection is made with the nipple, surrounds the cylindrical upper portion 25a of the nipple cover 25, as an aid in positioning the connecting means. A cover 67 is provided for cannula 65, and is removed when it is desired to use the filling set. a
Can connector fitting 61 is also provided with an air passage 68 therethrough, which has an enlarged outer portion in which a filtering material 69, as a wad of cotton is received. The fitting 61 includes a first or plug portion 76 which is inserted through the opening in the end surface 60 of the can, and has a curved wall surface which engages the inturned portions of the end wall, formed when the can is punctured. Fitting 61 has a shoulder 71 which seats against the end surface 60 of the can. An outwardly extending flange 72 is deformed upon connection of the fitting with the can and seals tightly against a surface 60. The flange '72 is of a rather thin and fiexible material so that a good seal is effected.
The can of bulk formula material preferably has a series of ribs diia formed in the end surface 6i) thereof, adding to the strength of the container. A relatively small circular fiat area 69b is left in the center of the end. The opening which is formed in the end of the can to receive fitting 61 must be properly located in the central porton of area 60b so that flange 72 has a flat surface against which to seal. A can opener or punch for providing a properly positioned opening is illustrated in FIG- URES 13 and 14. The opener includes a handle 71), only a portion of which is shown in the drawings, having a pair of hooked members 71 extending from one end thereof.
A cutter member 72 is affixed to the handle at a point spaced from hook members 71. The cutter has a round shank portion 73 and a cutting portion with an apex 74 and a plurality of planar cutting faces 75, of which there are at least three. Cutter 72 is so positioned on handle 71 that when the hook members 71 are engaged with the rim 33a of a can, the apex '74 of the cutter is centered on end member 69. The can opener is merely hooked with the can and the cutter is forced through the end member providing the desired opening. It is desirable that the opening be generally triangular, as it also has been found that such an opening is more reproducible than one which has more sides or is round. As the number of sides increases, there is an increasing tendency for the'material of the can end to tear. The cutting edges which join the planar faces of the opener sever the can material in such a manner that tabs 60c are'formed, which are turned back by circular shank 73 upon complete insertion of the opener. These tabs provide the surfaces with which the plug of fitting 71 is engaged.
After the can is opened and the connecting or filling set 43 attached thereto, a syphon action is used to cause gravity fiow of formula from the can 33 to a nurser. The opened can with a filling set 43 attached thereto is placed in one of the support openings 32 on the shelf 31. The
cover 67 is removed from the connector device 64 of the filling set and cannula 65 is connected with an empty nurser. A flow of formula is started by pulling on the tab 77 which extends from the bottom body section 22 of the nurser. This opens the nurser reducing the pressure therein allowing atmospheric pressure to force the formula from can 33 through the filling set 43 to the nurser. Only filtered air is admitted to can 33 through filter 69, preventing contamination of the contents. Once the fiow is started, it continues until the nurser is substantially filled. Then, as the cannula 65 is sealed with the hole 56 through nipple cover 25, the flow stops automatically.
The connection between the bulk container and the nurser 20 is then interrupted, as by inserting tubing 63 in the clamp 45, and the cannula 65 removed from the nurser, breaking the sealed connection. The cannula 65 is then inserted in a further nurser which may be filled by removing the tubing from clamp 45.
The system provides the utmost in sterility during the filling operation. The filling set 43 is a one-use device, thrown away when the container of formula is empty. Neither cannula 65 nor nipple 24 is touched during the filling operation. Cap 57 is merely removed from the nurser nipple cover and the cannula inserted. With the apparatus shown in the drawings, there are suificient nurser receiving positions that two nursers may be provided in which the cannula of the filling sets of the idle bulk containers are inserted, while nursers are filled from the third container. As best seen in diagrammatic FIG- URE 10, the filling set from a bulk container 33 in the left-hand bulk container support position will reach nurser positions 37 and 4b; the set from bulk container 34 reaches positions 38, as and 41, while the set from container 35 reaches positions $9 and 41. Cannula 65 is only momentarily exposed to the atmosphere when it is being moved from one nurser to another. Nipple cover 255 is not removed until it is time for feeding.
It is desirable to use two of the nurser receiving positions of base 29 for the active filling operation. While the filling set 43 is connected with the nurser in one position, an empty nurser is placed in the other position. As soon as one nurser is filled, tube 63 is closed off and connector 64 moved to the empty nurser and the tube released so that the flow of formula continues. Cap 57 is replaced on the filled nurser, the nurser is removed from the supporting position on the base and an empty nurser put in its place.
Shelf 31 is preferably offset from the base 2% so that the forward edge 31a, over which the filling tubes 63 pass, is directly above a line midway between the front and rear rows of nurser receiving portions in the base. The tubing is of sufficient length to reach at least two nurser receiving positions, without being long enough for cannula 65 to touch the base surface if the tubing hangs free.
The cuts 54 and 55 in the nipple are of different length, as is apparent from an examination of FIGURE 9. The illustrated arrangement permits insertion of the connector cannula, without having an excessive feeding rate which would occur if both cuts were of the longer length.
It is desirable to provide nursers in varying sizes so that different quantities of formula may be made up, according to the needs of the infants in the nursery. Generally speaking, nursers of the general type illustrated herein may be designed to have different capacity by changing the diameter, and to a lesser extent, the height. The nurser receiving portion of the base is best seen in FIG- URE 5. In the embodiment illustrated, three concentric but vertically and laterally spaced generally annular surfaces Stl, 8i and $2. are provided for nursers which may have a volume of two ounces, three ounces, and eight ounces. In each case, the annular sealed portion 23 of the nurser provides a nurser supporting surface which is received on the appropriate surface of the base. The vertical spacing of the supporting surfaces is such that the top of the nipple cover of the smallest size nurser, resting on the lowest supporting surface 89, is approximately one inch above the upper surface of the base. This provides ample leeway in the selection of the length of tubing 63 without increasing the danger of contact of the cannula with the base.
It is preferable that the recessed nurser receiving portions of the base be joined, as best seen at 84, in FIGURE 3, providing a channel through which the connecting device M of the filling set may be swung, further reducing the danger of striking the base and contaminating the cannula. Similar channels may be provided between the receiving portions in the two parallel rows. Channel 84 also provides an opening for handling the nursers.
The apparatus and method described above facilitate the use of throw-away nursers by providing a sterile and relatively foolproof means for filling. In a hospital, for example, not only is the problem of collection, washing, sterilization and reassembly of nursers completely eliminated but filling is provided for in a sterile manner where there is no danger of contact between the nurser nipple and a contaminated surface. The nipple cover remains securely fixed in place on the nurser until it is actually time to feed the infant.
In home use, it is normally not necessary to use more than one type of formula at any given time. Accordingly, modified filling apparatus and methods may be used. In FIGURE 11, a nurser 20 is shown in a stepped stand 9t? provided with a plurality of concentric, vertically and laterally spaced annular supporting surfaces. A portion of the stand is cut away at 96371 to facilitate insertion and removal of the nurser.
The filling apparatus include a funnel 92 provided with a spike or cannula 93 at the outlet thereof, which is inserted through the hole in nipple cover 25 and into nipple 24, sealing with the cover. A sleeve 94 surrounds cannula 93 and closely engages a cylindrical portion 25a of the nipple cover, supporting funnel 92 thereon. An elongated member 95 is provided with a stopper portion 96 which may be inserted in the bore 93a of cannula 93. A shoulder %a limits the extent of insertion of stopper 96. With the funnel 92 in place on an empty nurser carried in the support 99, an appropriate amount of formula may be placed in the funnel from a bulk supply. The stopper is then removed and the formula flows by gravity into nurser 2th, expanding it. During this portion of the operation, stopper member may be hung within the funnel 92 by placing the hook extension 97 over the upper funnel rim. When the formula has filled the nurser, flow stops and the stopper may be replaced and the funnel removed. The filled nurser is taken from the support and replaced with an empty nurser and the funnel again mounted on top of the nipple cover. The operation is then repeated to fill as many nursers as may be necessary. The wall of funnel 92 is preferably stepped and calibrated to indicate the quantity of formula therein.
The use of a throw-away nurser in the home eliminates the need for investment in sterilizing equipment and the periodic job of scrubbing bottles, nipples, caps and associated devices. It is only necessary to wash and sterilize funnel 92 and stopper which are preferably of a suitable high temperature plastic material, as a high density polyethylene and may be sterilized by boiling. The disposable nurser and the filling apparatus illustrated in FIGURES l1 and 12 are particularly suited for use where it is inconvenient to use conventional nursing equipment, as on a trip.
While we have shown and described certain embodiments of our invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims.
