I,we GORAN SJONELL, a Swedish subject of 11 Askrikevagen, S-181 46 Lidingo , Sweden,

Adapter for drip unit
This invention relates to an adapter for a drip unit a chamber, application hose, clip and probe for enteral nutrition. The artificial supply, for example, of nutrients usually is carried out by means of drip, enteral nutrition or parenteral nutrition. The package, us ually a flask, containing the nutrient is suspended upside down, and the nutrient is supplied via a drip unit either intravenous or via a probe directly to the stomach. When the nutrient is supplied from a flask, the visual observation of the filling degree of the flask does not involve problems.
For economic as well as hygienic reasons, disposable packages holding the nutrient are now being used to an increasing extent, which packages are intended for direct use at the application occasion. In view of varying storage times and of the necessity of protecting the contents in the package against exposure to light for a longer period, the disposable package must be capable to prevent light from contacting the contents,
which means that the packing material must bar the light and, consequently, is non-transparent. For being safe that the package is not emptied without the medical staff knowing about it, it is a fact based on experience that such disposa&Upackages are exchanged with an ample time margin. This implies waste, which in view of the high costs of the packages and their contents involves for the health service at large very great economic losses.
The conventional can packages, therefore, have not,come into use to a large extent, but flasks are still used, in spite of the requirement of limited storage time and of the higher cost.
The present invention as it is defined in the characterizing clauses of the claims, has the object to render it
possible to use disposable packages in the form of cans a.o. for parenteral and enteral nutrition. The invention further renders it possible to provide the disposable packages with the known type of closure, which can be broken up and torn off.
The invention is described in greater detail in the following, with reference to the accompanying drawings, in which Fig. 1 shows the invention applied to a disposable package in the form of a can, Fig. 2 is a section of the plug-like portion of the invention, Fig. 3 is a view from above of the portion according to Fig. 2, Fig. 4 shows another embodiment of the plug portion provided with means for penetrating the packing material, and Fig. 5 is a view from above of this embodiment.
The disposablqpackage in the form of a sheet metal can is designated by 1. This package is provided in known manner at one end surface of the can with a closure in the form of a notch defining the opening. The notch can be broken up and torn off by means of a grab ring. The can
1 is shown suspended in a suitable way, for example by means of a hook 2. In the opening a member 3 in the form of a plug is attached which will be described with refer ence to Figs. 2 and 3- From said plug 3 an aeration tube
4 extends all the way to the vicinity of the can bottom and connects the can interior to the atmosphere.
Fig. 2 is a section of the member 3- From a recess 5 of the member facing to the can interior, a first through hole 6 extends and terminates in a spout 7. A second through hole 8 is provided to receive the aforesaid aeration tube lJ. The member 3 further is provided with a third through hole 9, which preferably opens into a flange 10 formed in the member. To said flange a tube or hose 11 is to be connected, as will be described below

The configuration of the member, as can be seen in Fig. 3, corresponds to the configuration of the can opening. The member is made of a material permitting the member to sealingly be pressed like a plug into the can opening.
To this object, the member preferably can be provided with a peripheral guide of some kind and with a recess 12 co-operating with the edges of the opening and fixing the member.
The chamber 13 (Fig. 1) included in conventional manner 10 in the drip unit is intended to be attached with press fit on a shoulder l1! in the member, which shoulder co-axially surrounds said first hole 6. The drip unit further according to a known pattern comprises application hose, clip and probe.
The transparent tube or hose 11 is intended to be held extending along the outer surface of the can, whereby the liquid level 15 in question in the can can easily be observed in the tube 11. For correctly supporting the tube 11, the can is provided with a socket 16 about 20 the can bottom, which socket includes a slit or aperture 17 holding the tube in the position shown in Fig. 1.
The socket 16 further is provided with a flap 18, which normally is folded down to abut the side of the can, as indicated by dash-dotted line. When the can is to be susp-25 ended on the hook 2, the flap is drawn in the longitudinal direction of the can past the bottom, as shown in Fig. 1. The flap is provided with a hole for the hook 2.
The can preferably can be delivered with the socket 16 in place, and the member 3 with the drip unit as an acc-30 essory set. When the can is to be used, it is positioned, for example, on a table, the closure of the opening is torn off, the member 3 with the aeration tube is applied in the opening, and the tube ^ is attached in the hole 17. The drip unit with chamber 13 already is
Z03648
ii applied on the member 3, or it may at this step be applied thereon. The can now is turned to its position of use, and the flap is drawn up to the position shown in Fig. 1. The can is then ready to be suspended and used.
In Figs. 4 and 5 another embodiment of the adapter according to the invention is shown. The details, which in respect of their function and substantially of their configuration correspond to the adapter shown in Figs. 1-3, have been given the same reference numerals as in Figs. 10 1-3- The member 3 described with reference to Fig. 2,
thus, comprises the three through holes 6,8 and 9, the spout 7 and flange 9. The member also shows the shoulder 1^ for the chamber 13 in the drip unit. The adapter shown in Figs. and 5, however, differs from the one 15 described ab^ve in that the member is provided with a cutting means known per se in the form of a triangular pyramid body, the edges 19 of which form walls terminating in a tip 20. The body proper can be manufactured of hard plastic, while the tip 20 is of metal. The base 20 of the edges or cutting edges 19 extends with an inclined surface 21 slightly outside the connection of this annular adapter member 3 to the cutting body. The upper boundary surface of the adapter member 3 is located at a short distance from the base edge of the cutting edges 25 19. This distance corresponds in principle to the sheet metal thickness of the can in the place where the adapter is to be attached. The can metal sheet is shown in Fig. and designated by 22. The adapter member 3 further is provided with a gasket 23- For rendering the rec-30 ess 5 of the member 3 capable to act in the way intended, the disc-shaped edges are provided in the base portion with recesses 24 and thereby ensure supply flow to the hole 6. In the case referred to with reference to Figs. U and 5, thus, the adapter proper is used for
.364?
bringing about a hole in the can material, in that the cutting edge of the adapter with the edges 19 is pressed through the can material until the adapter member 3 with the gasket 23 abuts the same. The adapter thereafter is 5 slightly turned so that the can material engages beneath the projecting edges 21 of the cutting edges. The adapter now is sealingly attached to the can bottom. The aeration tube 4 is inserted through the opening 8, and the adapter is ready for use. It may be suitable, depending 10 on the appearance and size of the adapter member 3, to provide the member with some kind of handle or hold (not shown) for applying the adapter to and turning it through the can material.
The adapter according to the invention, of course, can c
be designed in different ways within the scope of the invention. The position of the holes in the member, for example, can be varied relative to each other, and also the means for applying the chamber on the member. The tube 11 may be a hose or a rigid tube bent in a suitable 20 way. The socket 16, of course, can be formed with a plane flange or with radially directed loops for applying the tube 11 and for suspension on the hook 2.
