Description

POLYCHLORIUM SILVER DRAIN PIPE

The utility model relates to medicine, namely to devices for removing fluids from body cavities.

For drainage of various cavities, including the pleural cavity, tubular drains are used, which are fixed with a thread. The thread is stitched through the skin in the area of the drainage hole, a knot is knotted to form a bridle, the drainage tube is fixed by knotting.

Along with other properties of the drainage tube, such as convenient and reliable fixation, the possibility of shortening a fragment of the tube introduced into the cavity by pulling are taken into account.

A feature of the drainage tube for the pleural cavity is that when it is introduced, it is not always possible to accurately determine the required size of the endothoracic fragment. If the drainage tube is located in the pleural cavity for a long time, it may be necessary to shorten the endothoracic fragment (pulling), for which the fixing thread is removed and repeated suturing is performed.

As an analogue, the author offers a drainage tube made of tubular silicone rubber (Surgical Surgery. / Ed. I. Littmann.- Budapest, Publishing House of the Hungarian Academy of Sciences, 1982.- P.77-77.).

The drainage tube is made of tubular rubber and has a length of 40 s: m and an outer diameter of 8 mm. At the working end there are three side holes with a diameter of 3 mm, located at a distance of 3 cm from each other.

Advantages of silicone rubber drainage tubes:,

- do not irritate tissues,

-reliable fixation with a thread that, as it were, cuts into the soft wall of the drainage without the possibility of mixing;

- can be autoclaved. The disadvantages are:

As a prototype, the author proposes a drainage PVC pipe (Moroz M.A. Method of fixing the drainage tube according to M.A. Moroz. // Bulletin of discoveries, inventions N 21. 07.06.92.- N1738290).

The drainage tube is made of polyvinyl chloride, has a length of 40 cm and an outer diameter of 5 mm. At the working end there are three side holes with a diameter of 2 mm, located at a distance of 3 cm from each other, the end end is open. For fixation, stainless steel wire is used, which is twisted with a ring until a tight compression is achieved, in which the wire cuts into the tube wall. A ring of steel wire is sewn to the skin with silk thread.

Advantages of PVC drainage tubes:

low cost

- released in sterile factory packaging,

- have a slight irritating effect on the tissue. Disadvantages of drainage PVC pipes:

-for fixation, a stainless steel construction is used, which is expensive, time-consuming to use, poorly tolerated by patients as an additional foreign body,

- the use of fixing a PVC pipe with a silk thread is unreliable, since the tube is quite stiff, and the silk thread quickly "relaxes, resulting in a tube falling out.

The author proposes a drainage tube (Fig. 1).

The drainage tube consists of a polyvinyl chloride tube (1) with a length of 40 cm and an outer diameter of 5 mm, at the working end of which there are three side holes (2) with a diameter of 2 mm at a distance of 3 cm from one another. Its end end (3) is open. At a distance of 10 cm from the working end, a cuff (4) is put on it from a sterile red tubular rubber dissected on one side (5) of a width of 4 cm. The drainage is fixed by nshyu. Thread about
