RU58365U1 - DRAINAGE FOR DRAINING ABCESSES OF THE ABDOMINAL CAVITY AND FOREIGN SPACE - Google Patents

Abstract

The drainage for drainage of abscesses of the abdominal cavity and retroperitoneal space consists of tubes 1 and 6 with openings 3 and 7, the tubes have different diameters and are inserted one into the other, and the parts of the tubes 1 and 6 located outside the patient’s body are separated with each other while maintaining sealing in at the joints 5, one or more tubes 6 serve to irrigate the cavity, and another or several other tubes 1 to remove the contents of the cavity. Drainage is simple and convenient for the surgeon and allows you to perform suction-flushing drainage using a single drainage system.

Description

The proposed utility model relates to abdominal surgery and is intended for aspiration-washing drainage of postoperative abscesses of the abdominal cavity and retroperitoneal space.

A prerequisite for the treatment of abscesses of the abdominal cavity and retroperitoneal space is the completion of the operation by drainage of the abscess cavity. The most commonly used for drainage of the abscess cavity are single-lumen drainage tubes. (1) The main purpose of such drainage is to remove the contents of the cavity. However, this excludes the possibility of active influence on the inflammatory process in the cavity, or this effect is limited and difficult to implement due to the need for reliable sealing of the abscess cavity from the free abdominal cavity.

To eliminate these drawbacks, suction-washing drainage is used. For this purpose, a drainage system consisting of two tubes is used: one for the introduction of antiseptic solutions into the purulent cavity, and the other for aspiration of the wash fluid and exudate (2). However, this type of drainage requires the creation of a sealed system and additional suturing of the wound. If the drainage lumen is closed or it is clamped, the contents of the cavity may leak into the free abdominal cavity with the risk of infection.

The purpose of the claimed utility model is the creation of an effective drainage system that provides full sanitation of the purulent cavity.

The stated technical problem is solved in such a way that the drainage for the drainage of abscesses of the abdominal cavity and retroperitoneal space consists of tubes with holes, the tubes have different diameters and are inserted one into the other, and the parts of the tubes located outside the patient’s body are separated with each other while maintaining sealing in places compounds, one or more tubes serves to irrigate the cavity, and another or several others to remove the contents of the cavity.

A common feature between the prototype and the claimed utility model is the presence of tubes with holes, the hallmarks of the tubes are of different diameters and inserted one into another, parts of the tubes located outside the patient’s body are separated, sealing is preserved at the joints, and one or more tubes serve to irrigate the cavity, and another or several others to remove the contents of the cavity.

The drainage consists of two or more tubes of different diameters inserted one into the other (Figure 1). Larger tube 1

used to remove the contents of the cavity. In its part 2, which is located in the abscess cavity, there are side holes 3. In the part of the tube 1 located outside the body 4, a smaller diameter tube 6 is passed through the hole 5, which is used to administer an antiseptic solution. The diameter of the hole 5 is less than the diameter of the conductive tube 6, which provides sealing in the connection area. On the part of the tube of smaller diameter 6, located inside the tube 2, there are holes 7. This tube 6 is used to introduce the solution. After establishing in the cavity of the abscess, the inner tube 6 is fixed to the outer kapron ligature. A system for evacuation is connected to the outer tube 1.

An example of the use of drainage.

Patient B., 53 years old, was operated on for pancreatic necrosis. Multiple relaparotomies were performed. Two months after the start of treatment, an abscess of the right lateral canal was diagnosed. An abscess was opened and drainage of the claimed design was drained. A silicone tube 6 with an outer diameter of 3 mm is inserted into a silicone tube 1 with an outer diameter of 10 mm through a side hole 5. The inner tube 6 is modeled by the size of the purulent cavity. Drainage is fixed to the skin with a nodal suture. A flushing system is connected to the inner tube 6, and the outer tube 1 was used to remove the contents of the cavity. A week later, complete wound cleansing with the cessation of purulent discharge was noted, cavity size reduction, drainage removed. After 6 days, wound healing began.

The use of drains of this design allows you to perform suction-washing drainage using one drainage system and in the case of laparoscopic drainage to perform it through one additional trocar. In this case, one additional incision of the abdominal wall is performed. Drainage can also be made of standard tubes of different diameters on the operating table, which is simple and convenient for the surgeon. At the same time, the creation of multi-channel drains is possible at no additional cost. Due to the arbitrary length, the inner tube adapts to the size of the purulent cavity, which provides better irrigation of the cavity with an antiseptic solution. When using the proposed drainage, the closure of its lumen by purulent plug is excluded. With this drainage, it is possible to use all known vacuum systems, without the need for additional adapters to connect them and provide sealing.
