SE443720B - DROP CHAMBER FOR INFUSION AND TRANSFUSION EQUIPMENT - Google Patents

Description

8003075-2 and requires that the service staff have great skill.

The object of the present invention is to avoid the above-described disadvantages and to provide a device which facilitates mixing also for untrained persons, whereby the danger of liquid flowing out or of contamination taking place is largely eliminated. The handling of this device should also be time-saving.

According to the invention, a drip chamber of the type described in the introduction is characterized in that the liquid channel in another insertion pipe is connected to the other end of the hose, which has another aeration channel fixedly connected to this liquid channel. The drip chamber of the drip chamber is inserted through the closure of the container containing the infusion or transfusion solution. On the other hand, the plug pipe connected to the hose is inserted through the closure of the container containing the additive. By turning one or the other container, any liquid can then be transferred through the hose to the other or one container. If the liquid is stored in glass bottles, the transfer takes place by correspondingly changing the relative height position of the bottles. Otherwise, an aeration cannula must be inserted. If the liquids are contained in collapsible plastic containers, the liquid can be compressed from one container to the other container by compressing the arbitrary container. The device according to the invention has mainly the advantage that it forms a uniform tool, which serves both for transfer and for infusion. A closed system has thus been achieved. The closure of the container, which later serves as an infusion container, is perforated only once. The risk of contamination of the contents of the container is considerably reduced, and handling is time-saving. Disconnection of the two interconnected containers is avoided.

In the embodiment according to claim 4, it is important that the hose is closable, e.g. during ongoing infusion.

With reference to the accompanying drawing, a suitable embodiment of the drip chamber according to the invention is described below by way of example. In the drawing, Fig. 1 shows this embodiment of the drip chamber and Fig. 2 an example of the use of the tool.

The tool has a drip chamber 1, which is formed by an upper part 2 and a lower part 3.

The drip chamber upper part 2 is formed with a plug-in spout 4, which houses the liquid channel 5 and the aeration channel 6. The liquid channel 5 opens into the drip chamber lower part 3.

The ventilation duct 6 terminates in a recess 7. A fastening nozzle 8 adjoins the recess 7, to which a hose 9 is connected.

A hose clamp 10 is pushed over the hose 9.

To the other end 11 of the hose, the liquid channel 12 is connected in another plug-in spout 13, which is also formed with an aeration channel 14.

This ends in a bore 15, which at 16 opens into the open. A filter 17 is inserted in the bore 15.

The free-opening bore 15 can be closed by an end plug 18.

Fig. 2 shows two bottles suspended next to each other, one of which is filled with an infusion or transfusion solution and the other II contains the additive, for example a dry powder or the like.

Before using the bottles, they are first in a normal position, which is not illustrated in the drawing.

In use, the drip chamber of the drip chamber 1 is pushed through through the closing plug 19 of the bottle I. Furthermore, the insert pipe 13 is pushed through the closing plug 20 of the bottle II.

By correspondingly raising and lowering or turning the bottles, the solution can then be arbitrarily pressed from one bottle to the other or vice versa. This is easily possible with collapsible containers. After transferring the liquid, the hose clamp 10 can occasionally be closed off or opened. When using glass bottles, the liquid is transferred by adjusting their relative height position.

If e.g. the preparation prepared in vial II is dissolved in the infusion or transfusion solution, the liquid is returned from vial II to vial I. The hose clamp 10 is then closable.

A filter can be accommodated in the lower part 3 of the drip chamber, which retains foreign substances, such as undissolved crystals, rubber residues or the like. The line 22 leading to the patient, which has a hose clamp 23, is connected to the connecting piece 21.
