The invention relates to medicine, more specifically to surgery, and can be used in patients with surgical diseases for the treatment of purulent diseases and complications of soft tissue, musculoskeletal, abdominal and thoracic cavities, i.e. in General surgery, traumatology, gynecology, urology, surgery and other areas.

The purpose of the proposed drainage - the possibility of drained them of the cavity (purulent) evacuation of exudate as in option depressiveh actions, by type classic depressives drainage of Caffine (aspiration "in the air"), and suction, i.e. by creating a drained cavity constant vacuum. The proposed drainage allows the use of these two mutually exclusive options, but not by the replacement of one form of drainage to others, which is always traumatic, unsafe for the patient and it is not always possible to perform.

Foreign firms issue can be supplied to the CIS drains, consisting of a wide perforated tube and placed in its lumen narrower one-piece tube, ending with a face hole. In the literature these tubes are called depressives drainage Babcoke, although much earlier this construction was proposed Caffine (Chaffin R. 1034, 1942, 1948) (Fig 1). Aspiration connect to the internal t is ubke (2). When this negative pressure is created in the space between the walls of the tube, as drawn from the environment through a small multiple side holes of the outer tube (4, 5). Sucked the liquid and the air is rushing to end the bore of the inner tube (3) and dropped it into the jar collection.

The domestic industry also produces depressiivsuse silicone drainage tube drainage type of Caffine, upgraded Nih (1999). (2)

Monolithic tube of Caffine-Cantina divided lengthways (0) on two identical channel. A wide opening in the septum (3), located at the end of the tube, creates a message between the two channels. In addition, one of the channels (1) has several side holes of relatively small sizes (4, 5). Aspiration connect to the channel, not having lateral perforations (2). Exudate and air are sucked into the channel with side holes (1), and move it to the end of the tube, where through holes in the partition (3) go to the second channel (2) and evacuated in a jar collection.

To the channel, the suction air, usually connect drip washing liquid.

These tubes are useful for drainage of the abdominal cavity in peritonitis, abscesses of the abdominal p is lost, not hermetic cavities and cavities sealed at the time of surgery, not able to dermatitits in the postoperative period.

If depressives drains used in leaky or poorly sealed cavity, drainage of sealed cavities and implementation of closed aspirazione-washing treatment has been developed (A.S. 808085 from 03.11.80) and produced by domestic industry tube TIMC (tube medical multichannel silicone).

It is also a dual version of the drainage tube (figure 3), only one of the channels - emergency (1) - occupies the main part of the lumen of the tube. Another channel is a microchannel with a diameter of only about 1-1 .5 mm takes place inside the segmental thickening of one wall of the tube (2). In the process of working through a venous catheter in a narrow channel drainage tube from the drip served any leaching solution, which, after reaching the opposite end (3), immediately sucked in a wide evacuation channel, razzhizhaya this thick purulent mass and preventing the plugging of the channel. Due to the underpressure in the Bank-book, created by the suction, pus from the cavity through the perforations (4) in the wall of the wide channel drainage together with a wash liquid comes in a jar-the collection.

Perejil is by us depressives and suction drains fairly well operate respectively with the presence of oxygen or its absence. However, the drainage suction action that is effective in terms of application in a sealed cavity, will be ineffective, and sometimes dangerous for the patient in terms of the depressurization of the cavity, for example, in the development of messages cavity intra-abdominal abscess drained from the hollow organ of the gastrointestinal tract; dehiscence tightly sutured wounds, and much more.

Not less frequent and the reverse situation requiring replacement depressiveh drainage by suction, such as a very slow obliteration of a purulent cavity with the disappearance of the threat of the development of internal intestinal fistula and other

In these situations create the need to replace one variant drainage other function on the suction repressively. However, as a result of changes in the clinical situation of the patient in the treatment process, which occurs very often in medical practice, unfortunately, the replacement of one drainage to others, as a rule, very traumatic, unsafe for the patient and even not always feasible, and therefore sometimes have to resort to surgical intervention.

Thus, known up to the present time, domestic and foreign drainages, including each of the above, perform the inherent function, but not able to think the bridges, go on another principle, i.e. from depressiveh to the suction and Vice versa. This need occurs in surgery very often. For example, if there are no or very slow obliteration of the cavity it is necessary to move from depressiveh drainage to the suction for maximum convergence of the walls of the cavity. On the contrary, if the drainage intra-abdominal abscess suction drainage (type TIMC) showed signs of receipt of the intestinal contents, it is necessary to urgently replace the drainage on repressively. However, as we noted earlier, the replacement of one drainage other traumatic unsafe for the patient and not always feasible, and therefore often have to resort to surgical intervention.

Thus, the need arose for the creation of a universal drainage, which could, depending on changes in the clinical situation by a simple design change implemented by the surgeon to change the principle of operation of drainage with suction on depressive and Vice versa, without changing its location.

The present invention is the creation of a universal combined surgical drainage for more effective treatment by changing its functions (suction or depressive) depending on the clinical situation, in rez is ltate elementary operations (manipulations) of the medical staff, perfectly safe and atraumatic for the patient. That is, we are talking about the creation of such drainage, which can be changed depending on changes in the situation, in no way changing the location set in the cavity drainage.

Similar drainages in the world medical practice to our proposal not produced.

Analysis of scientific literature also confirmed their absence.

The aim of the present invention are reducing injuries in the treatment process, such as drainage, bandaging etc., reducing the number of complications by more rapid change of the function of drainage, elimination of interventions, including operational, when his replacement, a reduction in the duration of treatment is generally stationary and in particular, reducing mortality.

The problem is solved in that in the presents of us the drainage (see figure 1) type of Caffine (tube in tube - 4) narrower one-piece tube (1) is installed tightly in the broader perforated tube TIMC (2) thanks to "clamp", which is a tight-fitting ring, worn on narrow tube to prevent its displacement relatively broad, and that thanks to him, the same is removable (8). Tube TIMC required diameter must be fully prepared to work as described analoge and presented on figure 3, i.e. caused internal perforation holes (4) by the length of the corresponding drained cavity, cut the wall between the two channels 8-10 mm on the end that is placed into the cavity (6), and formed a "tongue" of the segmental thickening of the tube together with the microchannel at the opposite outer end of the tube (7), but (!) 1-1,5 cm below from planned beforehand introduced into a wide channel tube TIMC edge "clamp" on the part of the wide tube TIMC, located outside the patient, apply 1-2 outer sprocket holes (5) for admission of atmospheric air when the suction. In this prepared state drainage works well on the principle of "aspiration in the air stream, i.e. as depressives drainage, and, with the additional ability to apply the wash fluid and / or medication drugs, including antibacterial, microchannel "tongue" (7) wide tube TIMC and/or suction channel through the outer perforation hole (5) directly in purulent lesion (drained cavity).

To change the function of drainage from depressiveh on the suction will last 3-4 minutes For this it is enough to remove the inner tube (1) with clamp (8) and excise wall, wide lumen tube TIMC to the level (s) of the outer holes (5)without affecting segmentnode thickening of the tube wall with the passing there microchannel. After connection of the microchannel with a dropper, and a wide channel with a jar-collector drainage is ready for operation (figure 4, 5).

In another, even simpler version of the task can narrow tube to fix within broader (TIMC) clamp wave form or with the presence of through-channels, or other variants of its design, contributing to the entrainment of atmospheric air through the clamp. There is no need to form the outer holes in the wide tube, and to change the function of drainage required removal of a narrow tube with a clamp or its introduction into the lumen of the wide tube TIMC.

Drainage works in the following way. After his introduction in the purulent cavity connected microchannel in the zone of the tongue with a dropper filled proryvnym solution(9). The narrow inner tube (1) connected to the suction through the Bank-the collection (figure 4) While a vacuum is created in the space between the walls of the tube. Sucked in through the exterior openings (5) air and through the internal multiple side holes of the outer tube (4) the liquid rush to end the hole (3) the inner, narrower tube (1) and dropped it into the jar collection.

If you want to go to a suction drainage option (figure 5) it is necessary to remove the inner ties the second tube (1), excise the portion of the walls of the wide tube with an outer sprocket hole (5), the adapter and the usual odnoprovodnoi, to re-connect with a wide drainage channel with a jar-collector, and microchannel - with dropper (figure 5).

When the opposite action, i.e. if necessary transition from suction to repressively functions of drainage, it is enough to enter in a wide lumen tube narrower inner tube with clamp "clamp"on the outside of the walls of the wide channel of the tubes positioned outside the patient apply 1-2 outside the perforations. When air(Aero)carried out the design of the clamp is any sequence change the suction and repressively functions of drainage is provided by removing or inserting a narrow tube with a clamp of relatively wide lumen of the outer tube of the type TIMC.
