Description

f

The invention relates to medical technology, in particular to drainage devices.

The purpose of the invention is to improve the drainage process by eliminating the overlap of the openings of the drainage device with adjacent tissues, as well as ensuring the introduction of Hbtx drug substances in the drainage process. . 1 shows a device for surgical drainage, a general view; figure 2 is the same, in the longitudinal section of the end portion and the portion of the middle part of the device; fig.Z - cross section A-A of FIG. one; figure 4 is a cross section bb of figure 1; figure 5 is a cross section bb-bf.1.

Surgical drainage contains an elastic tube t having outside longitudinal ribs 2 with through longitudinal channels 3, and additional edges 4 are formed between the ribs 2. Each edge 2 has transverse cuts 5 displaced relative to each other along the length, In the middle part of the tube t between its ribs 2 are filled holes 6. At the ends of tube 1 there are elastic tubes 7 with elastic membranes on one end and elastic lobes 9 on others. The tube 1 has removable inflatable cylinders 10 with air ducts 11, indicators 12 with plugs 13. Inside tube 1 there is an additional tube 14, made hollow and perforated. On an additional tube 14, swabs 15 are fastened with the help of threads 16 through holes 17. Each tampon 15 may contain a sorbent inside which is suitable for sorption of biological fluids. The gap between the primary and secondary tubes 1 and 14 is sealed with plugs 18.

A device for surgical drainage is used as follows. The main tube 1 (without an additional tube 14 with tampons 15 and removed inflatable balloons 10) is introduced into the peritoneal cavity by known techniques. The cylinders 10 are put on and air is pumped with a syringe, determining the degree of filling of the cylinders 10 by inflating the indicators 12. After fixing the tube 1 in the scaling cavity, an additional tube 14 with a tampon 15. Yes is introduced into its lumen;

Further, with plugs 18, overlap the gaps between tubes 1 and 14 at the ends. The ends of the additional tube 14 are connected to a vacuum source through a collector (not shown) and evacuate the cavity of tube 1. The pathological contents of the abdominal cavity penetrate the inside of tube 1 through holes 6 prevent surrounding tissues from adhering to the openings 6 of tube 1, ensuring effective aspiration of fluid from the abdominal cavity. The liquid entering the cavity of the tube 1 is actively absorbed by the material of the tampon 15, large particles are filtered out and remain in the surface layer of the tampon 15, and the liquid part through the perforations of the additional tube 14 penetrates into its lumen and then enters the collection. To reduce the viscosity of the liquid, remove The space adjacent to the drainage is irrigated with liquid drug compositions, including proteolytic enzymes and other preparations.

When summarizing the medicinal compositions to the tissues, one or several additional channels 4 are used. 30 After this, after treating the surface of the membrane 8 with an antiseptic, it is punctured with a puncture needle and injected with a syringe (not shown) into one channel 4 or sequentially into several channels 4 drugs that slit through the slots 5 (the edges of the slits 5 when supplying drugs under pressure, forming an outlet) in the ribs 2 and the gaps between the petals 9 and the surface of the ribs 2 formed during defo mation petals 9

drainage. The presence of slots 5 in the 45 longitudinal ribs 2, as well as elastic lobes 9 prevents liquid from flowing from the abdominal cavity into the channels 4, since after stopping the supply of medicinal substances, the edges of the 50 slits 5 are closed, and the elastic lobes 9 fit tightly surface of the tube 1. After some time, the process of suctioning the liquid from the hacking cavity is repeated. The additional tube 14 with tampons 15 is removed from the plugs 18 before being removed and the liquid in it is removed one of the crimped additional tubes 1A is disconnected from the vacuum source and suction is continued for some time through the other end; after removing the contents of the tube 14, its end is also disconnected from the vacuum source and the additional tube 14 with tampons 15 is removed from the cavity of the drainage tube 4, while removing large particles accumulated on the inner walls of the tube 1 and the surfaces of the tampons 15. Then enter the drainage tube t t new extra tube 14

with tampons 15 as described above. Surgical drainage after completion of treatment is removed from the abdominal cavity by conventional methods.

The presence of channels 4 in the device ensures the effectiveness of irrigation with drugs of the abdominal cavity, and the presence of longitudinal ribs 2 - aspiration of exudate from the abdominal cavity with the exception of blocking its openings by surrounding tissues.
