The present invention relates to medical equipment, namely to surgical drainage, intended for the discharge of pathological fluid from the abdominal cavity.

Known surgical drainage wavy shape with a Central channel, which allows you to rinse the bottom of the wound and has an original fastening system (French patent No. 2681251).

However, the use of the fixing bracket in its design is not robust enough and traumatic to the surrounding tissue.

The most loved and accepted us for the prototype is surgical drainage with flexible longitudinal body wall thickness which is sufficient for removing exudate. The housing consists of part a for introduction into the affected area of the portion In which the guide. Part a and part b are formed on a straight angle, while the part a is transformed into an arc (Japan Patent 4-314454, Bulletin No. 4, 1994, issue 7, p.49).

However, the known surgical drainage has significant drawbacks. First, it does not provide effective and uniformly directed flow of wound exudate in the lumen of the tube, because its parts are formed at a direct angle, thereby reducing the speed of the current exudate, moreover, the angular bend drainage contributes to the formation of dense clots and obstructions that block the lumen of the drainage; secondly, his e is splatzie does not meet the principle of traumatism, because of the angular shape of the drainage does not provide an effective and congruent fit to the field drainage.

The technical result of the invention is to traumatism and smooth separation of wound exudate.

The technical result is achieved by the fact that surgical drainage is made in the form of a flexible longitudinal body, consisting of parts for injection in the affected area and the guide part.

New in the achievement of the technical result is that both parts of the drainage formed on diametrically opposite the Windows, which are outside the thin latex sleeve, while in the case of the insertion section of the drainage completed spaced round holes differentiated diameter.

Since both parts of the drainage formed on diametrically opposite the Windows, closed the outside thin latex sleeve, is provided with: first, unimpeded outflow of wound exudate is at difficulty drainage function alternately compress (invaginate) fingers latex sleeve, i.e. to reconcile diametrically opposite the window, therefore, to create alternating pressure, which restores the passage; secondly, due to the fact that the casing is made drainage spaced round holes of the WPPT is erentiating diameter, facilitated the introduction and effective operation of the drainage, thereby traumatism, faster execution and increased security for drainage; third, latex sleeve that connects the two parts of the drainage, provide solidity and ravnopravnosti elastic tube, allows you to quickly and correctly to vary the geometry of its installation in the drainage area, therefore, to meet the individual principle of selection of the drainage, to improve the comfort of the treatment.

Thus, the proposed surgical drainage provides unimpeded outflow of wound exudate, traumatism, speeds execution and improves the security of the drainage.

Comparative analysis with the prototype shows that the claimed surgical drainage is characterized by the fact that both parts of the drainage formed on diametrically opposite the Windows, which are outside the thin latex sleeve, while in the case of the insertion section of the drainage completed spaced round holes differentiated diameter.

Thus, the claimed surgical drainage meets the criteria of the invention of "novelty."

A new set of features provides unobstructed outflow of wound exudate, traumatism, accelerates and improves the security of drainage, therefore, the decision has "industrial is the first application".

The essence of surgical drainage is illustrated in the drawing, where 1 is part of the housing for insertion into the damaged area, 2 - directing part of the body, 3 - hole differential diameter, 4 - thin latex sleeve 5 is diametrically opposite the window.

Surgical drainage consists of a flexible longitudinal body, the wall thickness of which is sufficient for removing exudate, the housing consists of a part for insertion into the damaged area (1) and paragraph (2), which is the guide. Part (1) and part (2) are formed on diametrically opposite Windows (5), closed on the outside thin latex sleeve (4); on the housing part (1) made spaced round holes, differentiated diameter (3).

Surgical drainage is used as follows. End of part (1) is carried out in the abdominal cavity through an additional puncture of the abdominal wall at a point on 1-1,5 cm the more medially anterior-upper spine of the Ilium. Channel for conducting drainage done obliquely, so that the tube does not bend and had direction in the cavity of the pelvis, adhering to the parietal peritoneum. Carried out through the abdominal wall and intra-abdominal end of the drainage (1) with differentiated holes (3) are individually bent and placed on the bottom of the pelvis (the girls behind the uterus)so that between the drainage tube and the wall and pelvic cavity were not pressed intestinal loops. The correct position of the drainage shall be checked visually or by palpation. Intra-abdominal end of the drainage tube (1) shall not extend beyond the pelvis. Part (2) of the drainage stack on the skin of the abdomen toward the armpit. Closest to the skin part (1) of the drainage fixed anchor suture. Surgical wound is sutured closed. The end of the guide part (2) drainage is lowered into the tank at floor level. Properly installed and fixed for skin drainage immediately self is filled with liquid contents of the abdominal cavity. To enhance the draining effect periodically conduct simulated convergence of the walls of the latex sleeve (4) through diametrically opposite the window (5), create alternating pressure and restore the patency of the drainage tube. Provide effective drainage of wound exudate, after which the tube removed.

Example: the Patient M, 12 years. Diagnosis: acute gangrenous appendicitis, local peritonitis. October 1, 2003 made retrograde appendectomy. At the final stage of the operation in the abdominal cavity is entered surgical drainage with a latex sleeve. Made passive drainage of purulent exudate within two days; scanty purulent hemorrhagic exudate easily drained from the abdominal cavity, kinking, twisting drainage tube and discomfort the patient was not observed. To enhance the draining effect (every eight hours) conducted a series of digital convergence walls latex sleeve through diametrically opposite window. On the third day the drain was removed. The wound healed by first intention. The patient is examined in 1.5 months. Found an excellent anatomical and functional outcome of the treatment.

Surgical drainage in the form of a flexible longitudinal body, consisting of parts for injection in the affected area and the guide part, wherein both parts of the drainage formed on diametrically opposite the Windows, closed on the outside of the latex sleeve that connects the two parts of the drainage, while in the case of the insertion section of the drainage completed spaced round holes differentiated diameter.
