Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an adapter for an infusion unit comprising a chamber, an infusion hose, a clip, and a probe for feeding nutrients into the intestines.

For example, the artificial supply of nutrients is performed by intravenous drip, ie, intraintestinal nutrition supply or extraintestinal nutrition supply. The container containing the nutrients, usually a flask, is suspended upside down and the nutrients are delivered to the stomach either intravenously via a drip unit or directly through a probe. When feeding nutrients from a flask, no problem arises in visually observing the degree of filling of the flask.

For economic and hygienic reasons, there is now considerable use of disposable containers for holding nutrients, and the containers are intended to be used directly during infusions.
Disposable containers must be able to prevent light from hitting the contents of the container, from the point of view of storage time and the need to prevent the contents of the container from being exposed to the light for long periods of time; , meaning that the material of the container must block the light rays, so that the material of the container is opaque. In practice, such containers should be replaced in good time, based on experience, to prevent the risk of medical personnel not knowing that the container is empty. This represents a waste in terms of the high cost of the container and the fact that the contents of the container involve a very large financial loss for health insurance.

Conventional cans have therefore not been widely used, although they have been used to some extent, despite their limited storage time and high cost.

The invention has the object of making it possible to use a disposable container in the form of a can for the supply of parenteral and intraintestinal nutrients as defined in the claims. The invention further makes it possible to provide a disposable container with a closure of known type that can be broken and pulled apart.

According to the invention, the container 1 has a chamber 13, an infusion hose, a clip and a probe, and is intended for a substantially disposable container 1 which, during use, occupies an inverted position.
An adapter for an infusion unit, consisting of a main member 3 adapted to be sealingly attached to the opening of the container, the main member 3 being provided with a pyramid-shaped cutting device for penetrating the container material, the main member 3 being provided with a pyramid-shaped cutting device for penetrating the container material, the main member 3 being fitted with The corner of the pyramid-shaped cutting device is provided with a notch 21 in a single plane coinciding with the wall of the container to be penetrated, the notch 21 receiving the container material between the notch 21 and the main part. , and is characterized in that the main member is fixed to the container when the main member is rotated together with the pyramid-shaped cutting device.

The invention will be explained in more detail below with reference to the accompanying drawings.

A disposable container in the shape of a thin plate can is indicated by the number 1. This container is provided in a known manner with a closure in the form of a cutout defining an opening on one end face thereof. The notch is broken and pulled apart by the gripping ring. Container 1 is shown suspended in any suitable manner, for example by hook 2. Attached to the opening is a main member 3 in the form of a plug, which will be further described with reference to FIGS. 2 and 3. From said main member in the form of a plug, a vent tube 4 extends over the entire length of the container, close to the bottom of the container, and communicates the interior of the container with the atmosphere.

FIG. 2 is a sectional view of the main member 3. A through hole 6 extends from the recess 5 in the main part facing the interior of the container and terminates in a spout 7. A through hole 8 is provided for receiving the aforementioned vent pipe 4. Furthermore, the main part 3 is provided with a through hole 9, which preferably opens into a flange 10 formed in the main part 3. A tube or hose 11 is connected to the flange as explained below. As can be seen from FIG. 3, the shape of the main member corresponds to the shape of the opening of the container. The main member is made of a material that allows it to be pushed sealingly into the opening of the container like a plug. For this purpose, the main part may be provided with some kind of peripheral guide and a recess 12 which cooperates with the edge of the opening and fixes the main part.

Chamber 1 conventionally included in the IV unit
3 (see FIG. 1) is adapted to be press-fitted into a shoulder 14 of the main member coaxially surrounding the through hole 6. Infusion units of the type known in the art further include an infusion hose, a clip, and a probe.

A transparent hose 11 is adapted to extend and be held along the outer surface of the container so that the liquid level 15 in question within the container can be easily observed at the hose 11. In order to properly support the hose 11, the container has a socket 16 around the bottom of the container.
The socket has a slit or hole 17 which holds the hose in the position shown in FIG.

The socket 16 further includes a flap 18 which is normally folded downwardly so as to contact the side of the container as shown in dashed lines. When a container is to be hung on the hook 2, the flap is pulled along the length of the container and past the bottom of the container, as shown in FIG. The flap is hook 2
It has a hole for

Preferably, the container is carried into position together with the socket 16, and the main part 3 with the drip unit is carried as an accessory set. When using the container, the container is positioned, for example, on a table, the closure of the opening is pulled apart, the main part 3 with the ventilation tube 4 is attached to the opening, and the tube 11 is inserted into the hole 1.
Install it on 7. The drip unit with chamber 13 is already attached to the main part 3, but alternatively it can be attached to the main part 3 at this stage. Now turn the container upside down into the position for use and pull the flap up to the position shown in Figure 1. The container is then hung and prepared for use.

4 and 5 show embodiments of the adapter according to the invention. Details corresponding to the adapter functions, substantially the construction of the adapter, of the adapter shown in FIGS. 1-3 are given the same reference numerals as in FIGS. 1-3. Thus, referring to FIG. 2, the main member 3 has three through holes 6, 8, 9, a spout 7, and a flange 10. The main part also has a shoulder 14 for the chamber 13 of the drip unit. However, the adapter shown in FIGS. 4 and 5 is such that the main part comprises a cutting device known per se in the form of a triangular pyramid, the cutting blade 19 of which device
differs from the adapter described above in that it forms a wall that terminates in a tip 20. A suitable triangular pyramid, made of hard plastic, has a tip of 20
is made of metal. The bottom surface of the cutting blade 19 extends with an inclined surface slightly outward from the connecting portion between the main member 3 of the annular adapter and the cutting blade, thereby forming a notch 21 . The upper boundary surface of the main part 3 of the adapter is located at a short distance from the bottom edge of the cutting blade 19. This distance corresponds in principle to the thickness of the lamina of the container at the location where the adapter is to be attached. The container lamina is designated by the number 22 in FIG. The main part 3 of the adapter further comprises a gasket 23. In order to enable the recess 5 of the main part 3 to function as intended, the circular edge is provided with a recess 24 at the bottom, thereby ensuring a feed flow into the through hole 6. Thus, with reference to FIGS. 4 and 5, in this case a suitable adapter is used to make a hole in the container material, i.e. the cutting blade 19 of the adapter is connected to the main body of the adapter with the gasket 23. Until member 3 hits the can material,
Push through the container material. Then, turn the adapter slightly to remove the container material from the notch 21 of the cutting blade.
engage under the. The adapter is now sealingly attached to the bottom of the container. After inserting the vent tube 4 through the through hole 8, the adapter is ready for use. Depending on the shape and size of the main part 3 of the adapter, it may be appropriate to provide the adapter with some type of handle or retainer (not shown) for attaching the adapter to the container and for threading the adapter through the container material. It is.

Of course, the adapter according to the invention may be designed in different ways within the scope of the invention. For example, the positions of the holes in the main member may be changed relative to each other, or the chamber may be attached to the main member by a device. Hose 11 may be a rigid tube or hose bent in any suitable manner. Of course, it is also possible to form a socket 16 with a planar flange or a radially directed ring for attaching the hose 11 and suspending it on the hook 2.
