Abstract

The invention relates to medical technology. In order to provide simultaneous irrigation and drainage in the outer perforated tube 2 with the blind end 3, the inner tube 1 is located. The open end of the tube 1 is located with a gap relative to the blind end 3 of the outer tube 2. The inner cavities of the tubes 1 and 2 are separated by longitudinal partitions 4, 5 and 8 forming channels 6, 7, 9 and 10, with channels 9 and 10 of the inner tube 1 communicating with the drainage pipes 18 and 19. 8 il.

The invention relates to medical technology and concerns the construction of drainage devices used in surgery for the drainage of cavities.

The purpose of the invention is to provide simultaneous irrigation and drainage.

FIG. 1 shows a drainage with a settler; general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 - section bb In Fig 1; in fig. 5 is a cross-section of the FIG. one; in fig. 6 is a section DD-D in FIG. one; FIG. 7 is a sectional view E — E of FIG. one; in fig. 8 - LC section in FIG. one.

Drainage with a settling tank contains two coaxially mounted flexible polymeric inner 1 and outer 2 tubes connected at the proximal end of the device. The open working end of the inner tube 1 is located with a gap relative to the rounded blind end of the outer tube 3 of the outer tube 2. The longitudinal partitions 4, 5 form between the tubes 1, 2 non-communicating semi-annular longitudinal settling channels 6, 7. The channel of the tube 1 is divided by a longitudinal partition 8 into non-communicating channels 9, 10. The partitions 4, 5, 8 are located in the common axial plane of the tubes 1, 2. The distal and proximal ends of the tube 2 have respectively elliptical perforations 11, 12 for filtering the contents of the drained cavity and screw holes 13, 14. The perforations 11 and the hole 13 communicate with the channel 6, and the perforations 12 and the hole 14 communicate with the channel 7. The channels b, 9 and 7, 10 at the distal end of the device communicate with each other respectively through the holes 15 and 16. A nozzle 17 is connected to the proximal end of tube 1 with inlet and outlet connections 18, 19 communicating with channels 9, 10.

Drainage with a sump works as follows.

FIG. 2

The distal perforated drainage area is inserted into the body cavity, while the proximal section with nozzles 18, 19 is located outside. One of the pipes, for example, 18, is connected through a collection vessel (not shown) to a vacuum source, and through the other pipe 19, irrigation liquid is fed, which through channel 10, opening 16, settling channel 7 and perforations 12 goes to the surrounding sticking to the drainage tissue (the vent hole 14 is blocked). The flushing fluid is removed from the cavity through perforations 11, a settling channel 6, an opening 15, a channel 9, and a fitting g 18 into the collection vessel. During the aspiration of the wash liquid, air enters the settling channel 6 through the vent hole 13. This drainage can also be used as a conventional drain with a settling tank. At the same time, filtration of the content of the drained cavity occurs simultaneously through perforations 11, 12 into settling channels 6, 7, through openings 15, 16 enters channels 9, W, nozzles 18, 19 and further into the general evacuated collecting vessel, with in which the pipes 18, 19 are connected. During the drainage, air flows into the settling channels 6, 7 through the vent holes 13, 14.
