RU174545U1 - DEVICE FOR ACTIVE ASPIRATION OF ABDOMINAL LIQUID - Google Patents

Abstract

A useful model is a device for active aspiration of fluid from the abdominal cavity, including two square sheets of polyethylene film 40 cm in size with holes 0.2-0.7 cm in diameter with a frequency of 4-16 holes per 1 dm, between which there is a square gauze of the same size, connected through a vinyl chloride tube to an active aspiration apparatus. The proposed device is simpler than the known one and is not inferior to it in efficiency.

Description

The proposed utility model relates to medical equipment, namely, to devices for surgical operations, and may find application in aspiration of fluids from the abdominal cavity.

The problem of removing fluid from the abdominal cavity is especially relevant in the treatment of peritonitis.

A device for aspirating fluid from the abdominal cavity during laparoscopic surgery (see RF patent No. 2178317, IPC A61M 27/00, publ. 20.01.2002), consisting of an insufflator, a fluid receiver, a vacuum pump, a system of tubes and trocars, in which the fluid receiver and the vacuum pump through a system of tubes and trocars form a vicious circle with the abdominal cavity.

The disadvantage of this device is that it is designed for occasional removal of fluid in a short period of time and does not guarantee complete evacuation of fluid from the abdominal cavity.

Closest to the claimed device is a patent for PM of the Russian Federation No. 126587 "Device for active aspiration of fluid from the abdominal cavity", IPC A6117 / 00. publ. 04/10/2013. This device contains soft drainage, consisting of 2-4 strips of hollcon, 65-75 cm long, 5.0-6.0 cm wide and 0.5-1.0 cm thick, laid crosswise and soldered into 0.2 perforated polyethylene -0.7 cm with a frequency of 4-16 holes per 1 dm ² , connected through a vinyl chloride tube to an apparatus for active aspiration.

The disadvantage of this device, which is the prototype of the proposed, is the complexity of the preparation.

The objective of the utility model is to simplify it and reduce the complexity of manufacturing the device.

The problem is solved by a device for active aspiration of fluid from the abdominal cavity, including two square sheets of plastic film 40 cm2 in size with holes 0.2-0.7 cm in diameter with a frequency of 4-16 holes per 1 dm2 between which there is a square gauze of the same size, connected through a vinyl chloride tube to an active aspiration apparatus.

Clinical example.

Patient M., 62 years old, was admitted on November 21, 2015, on the 3rd day of illness with complaints of nausea, vomiting, and abdominal pain. Diagnosed with diffuse peritonitis. After preoperative preparation, a wide median laparotomy was performed. In the abdominal cavity, gangrenous-perforated agendicitis with perforation at the base and abscessed, 300 ml of pus was found. Intestinal loops are hyperemic, swollen, swollen, covered with layers of fibrin. An appendectomy with immersion of the stump in purse string and Z-stitches was performed. The abdominal cavity is sanitized. The above described soft drainage is applied to the intestinal loops. The edges of the soft drainage are immersed in the abdominal cavity: small pelvis, right and left lateral canals, subhepatic space. A large surgical swab is placed on the soft part of the drainage, into which the abdominal part of the vinyl chloride tube is inserted inside the right mesogastric tube through the channel formed in the abdominal wall and connected to the device for active aspiration. The incision is sealed with surgical plastic wrap.

Further treatment of patient M. was continued in the intensive care unit. 24 hours after the initial intervention, abdominal programmed sanitation was performed. Soft drainage was removed from the abdominal cavity. The abdominal cavity is drained, sutured tightly. The postoperative period was uneventful. The wound healed by first intention, On the 12th day the sutures were removed. Patient M. was discharged for outpatient aftercare.

Thus, a device for active aspiration of fluid from the abdominal cavity contributed to the relief of peritonitis and primary wound healing, which testified to the effectiveness of the proposed model.
