Description

This invention relates to a medical technician and concerns the construction of drainage devices used in surgery for the drainage of cavities.

The purpose of the invention is to regulate the process of drainage.

Figure 1 shows the surgical drainage in the active drainage mode, a longitudinal section; Fig. 2 shows surgical drainage in the mode of passive drainage, a longitudinal section; in FIG. 3 - section A-A in FIG. one.

Surgical drainage contains coaxially installed flexible polymer tubes — internal 1 and 2, connected to one another and forming the central drainage channel 3, and the external 4 with perforations 5 in the distal working area. Between the tubes 1, 2 and 4 there is an annular channel-sump 6. At the distal end of the drainage, there is a rounded tip 7 with a rigid short tube 8, on which is mounted an internal elastic tube 1, reinforced with a cylindrical spring 9, which prevents the tube 1 from dropping during active drainage. The tube 1 between the turns of the spring 9 has through slots 10.

Tubes 1 and 8 at the distal end have diametrically opposed openings 11 and 12, through which the central channel 3 communicates with the annular channel 6. The outer tube 4 at the proximal end has vent holes 13, a portion 14 with an external tapered thread and a nut 15 with an inner tapered thread. When screwing the nut 15 onto the section 14, the latter evenly compresses the non-expandable tube 2, ensuring tight fixation of the tubes 2 and 4 one relative to the other. On the outer surface of the inner tube 2, check marks (not shown) are provided for indirectly determining the length of the elastic reinforced tube 1.

Drainage works as follows. The distal perforated drainage site is inserted into the body cavity. In addition, a proximal portion with vent holes 13 is located outside. The end of the tube 2 is connected through a collection vessel (not shown) to a vacuum source. In the active drainage mode (Fig. 1, the edges of the slots 10 are closed) the fluid is filtered from the cavity through perforations 5 of the outer tube 4 into the settling channel 6 and then is forced out of the latter by air entering through

vent holes 13. Next, the liquid through the openings 11 and 12 of the tubes 1 and 8 and the central channel 3 enters the collection vessel for recording and laboratory control. The process of aspiration of fluid drained

the cavities are controlled by blocking the vent holes 13.

If necessary, periodic irrigation of the drainable cavity solutions of medicinal substances to the surrounding drainage

The tissues are fed through the central channel 3, the holes 12 and 11, the settling channel 6 and the perforations 5 (the ventilation holes 13 are blocked).

In order to provide passive drainage, the condition shown in Fig. 2 is attached to the drainage: the nut 15 is unscrewed, the tubes 2 and 4 are displaced one relative to the other, guided by control marks (not shown) on the surface of the inner tube 2, and then screwed on the nut 15 . provide tight fixation of the tubes 2 and 4. After stretching the reinforced elastic tube 1, the perforations 16.

the openings 13 are covered by an elastic coupling 17. The outflow of fluid from the cavity is carried out through the perforations 5, the settling channel 6, the perforations 16, the openings 11 and 12, the central channel 3 and further into the collection vessel.

Periodic irrigation drained

the cavities are carried out by feeding solutions of medicinal substances through the central channel 3, perforations 16 of the elastic reinforced tube 1, holes 12 and 11,

channel-sump 6, perforations 5 of the outer tube 4 to the surrounding drainage tissues.
