DE8421444U1 - FLAT DRAIN FOR DISCHARGING SECRETS - Google Patents

Description

The invention relates to a flat drain for draining secretions, Blood or the like consisting of the wound cavity of a patient * made of an easily compressible plastic hose, on its inner wall in the longitudinal direction of the hose and in parallel mutually extending ribs are arranged at a distance from one another.

In a known embodiment, the width corresponds to Ribs approximately the clear distance between the ribs, so that when the hose is compressed flat, the ribs of the one flat side zipper-like in the groove-shaped depressions on the other flat side. The discharge of secretions, blood or the like. is then no longer secured.

The invention is based on the object of developing a flat drain in which a long-term drainage function is guaranteed is.

This object is achieved according to the invention in that the ribs are made much wider than the clear space between two ribs.

It is useful if each rib is about twice as wide is like the space mentioned.

The ribs can be filled with air or gas. There is a flat drain Can be cut to length, it is in the arrangement of air-filled ribs useful if the ribs have closed air chambers, for example can be produced by separating welds or the like *.

The ribs only protrude into the interior of the hose, so that the flat drain expediently has a smooth outer jacket surface.

With the flat drain according to the invention, the number of ribs should be adapted to the lumen required in each case. There the ribs. are wider than the clear distance between the ribs, the webs serve as spacers when the tube is flattened and thus prevent a collapse and thus a lumen relocation under the action of pressure from the outside. The inside of the hose remains stable, so that a long-term drainage function is guaranteed.

In the area of the drain end intended for connection to the wound cavity Perforations can be provided between the ribs: to allow the secretions to enter the tube end from all sides to ensure.

Such a flat drain fits because of its high flexibility to the tissues and organs optimally, so that tissue irritation or even necrosis rarely occurs. Perforations e.g. des The intestines or the intestinal wall are not to be feared. However lead; these advantages in the area of the exit point of the hose from " the patient's body to disadvantages in terms of sealing; tion. Since the hose can be flattened very easily, j

kauiti to prevent secretions j blood or the like next to the hose 'runs down the patient's skin. Run this for the Patients not only extremely uncomfortable but also It is useful if to avoid unsanitary disadvantage the drain end intended for connection to the wound cavity with a plastic drainage tube that is rigid against radial pressure Connected is. The usual plastic drainage tube has a high rigidity against external pressure, so that an optimal sealing of the drainage channel can now be achieved. That Secretion can be safely and sterile in a bag or the like via the tube. be derived.

The drawing is an example embodiment the invention shown schemati sch. Show it:

FIG. 1 shows a cross section through a surface drain;

FIG. 2 shows a section along the line II-II in FIG and

FIG. 3 on a reduced scale in a plan view

connected with a plastic drainage tube Flachdrai η.

The flat drain 1 shown in Figure 1 consists of an easily compressible plastic hose on the inner wall ■ fcn hose longitudinal direction and parallel to each other Ribs 2 are arranged, which have a clear space 3 between them, which is approximately half as wide as each rib.

If the ribs are filled with air or gas, they are subdivided the ribs by self-contained air chambers 2a (see Figure 2), which by separating welds 7 or the like. be generated.

The flat drain 1 has a smooth outer jacket surface 4 and is made from a flat sheet of plastic with the help of a longitudinal weld 6 manufactured.

According to FIG. 3, this is intended for connection to the wound cavity Drain end 1a with a rigid against radial pressure Plastic drainage hose 5 connected.
