Abstract

This invention relates to the field of medicine and can be used as a surgical drainage to remove pus and exudate from the abdominal cavity. The purpose of the invention is to increase the dredging properties. A detox swab contains strands of a selected size of porous carbon fibers wrapped in a layer of cellulosic fibrous material, such as gauze. The middle part of the roller containing porous carbon fiber and gauze is placed in latex thin-walled tubular sheath open on both sides.

The invention relates to medicine, namely to surgical drainage, and can be used to remove pus and exudate from the abdominal cavity.

The aim of the invention is to improve their properties.

The detoxification tampon contains a coated fibrous material, while as a fibrous material it contains carbon filaments with a burnt of 20–65 wt.% L with a porosity of 0.25–1, 20 CMV r.

The detox swab is a highly porous carbon fiber material wrapped with a layer of gauze and placed in latex thin-walled tubular sheath open on both sides. The length of the latex sheath is on the order of 1/3 - 1/4 of the length of the detox swab. The length and thickness of the tampon provided is provided depending on the specific surgical situation. For example, the length of a detox swab for drainage of periapentic abscesses is 20-25 cm, thickness 2.5-3 cm.

Detox swab is made as follows.

The carbon tow fiber or carbon fabric of the UUT-2 or UUT-2/4 grades is heat treated in an atmosphere of superheated water vapor or CO2 at 750–900 ° C to an obgar 20–65 wt%. At the same time, porosity with a pore volume of 0.25-1.20 develops, due to which tissue and microorganisms are directly adsorbed from purulent inflammation zone, the drainage capacity of the tampon is increased, and the composition can be used without changing it. for a long time, up to 6-7 days.

The selected size of the porous carbon fiber is wrapped with a layer of gauze (thicker of the gauze layer is provided depending on the size of the fibrous carbon sorbent burning, in particular, the greater the amount of the fiber, the thicker the gauze layer and vice versa) and placed in latex thin-walled tubular shell

The swab is placed in a plastic bag, sealed and sterilized on a v-ycTa bag.

Example 1. Ill., 54 years old, was operated on for acute perforated gangrene of SAD appendicitis, and periappendicular abscess. Angshendomi and abscess cavity drainage with a detoxification swab containing porous carbon fibers with about 65% shine and pore volume

1.20 CM Vr (80 wt.%) And a layer of gauze (-20 wt.%).

The postoperative period was uneventful. On the 3rd day after the operation, the body temperature returned to normal, on the 6th day the blood count, on the 2nd day peristalsis appeared. An intensive absorption of the separated purulent-hemorrhagic character was noted on the tampon for 3 days. On the 4th day, the number of the separated decreased, and on the 5th day, it stopped altogether. The tampon was removed on the 6th day. The wound healed by primary tension. The patient was discharged in good condition on the 10th day of the postoperative period.

Example 2. Patient B., aged 35, underwent transplantation of a cadaveric kidney in connection with the terminal stage of chronic renal failure. Against the background of uremic intoxication and intensive immunopressive therapy, extensive postoperative wound suppuration has occurred. After this, the patient's condition deteriorated sharply. When examining the wound edges are hyperemic, swollen in the area of the artificial renal bed - the intensity of inflammation. General and local therapy (ligation with washing the cavity of the wound and putting on rubber turundas) was not noticeable. In order to improve the drainage of the wound and create a functional, quietly inflamed tissue, it was decided to deliver a detoxification tampon containing highly porous carbon fiber with a 40% oil burnout and a pore volume of 0.75 cM Vr (90% wt.) And a layer of gauze (10 weight.%).

For 2 days on the tampon, intense absorption of the separated wound secretion was noted. On the 3rd day, its amount decreased, and on the 4th day it stopped altogether. The tampon was removed on the 5th day; there was practically no inflammation in the brine. Subsequently, with the preserved function of the kidney, the wound healed by secondary tension. The patient was discharged for outpatient treatment.

The proposed tampon has high draining properties. The intensity of drainage from a gauze swab 30%, and the proposed 80%.
