RU126587U1 - DEVICE FOR ACTIVE ASPIRATION OF ABDOMINAL LIQUID - Google Patents

Abstract

Device for active aspiration of fluid from the abdominal cavity, including soft drainage from 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 polyethylene with a perforation of 0.2-0.7 cm with a frequency of 4-16 holes per dm, connected via a vinyl tube to an apparatus for active aspiration.

Description

The proposed model relates to medicine, in particular to devices that adequately aspirate fluid from the abdominal cavity, especially in the treatment of peritonitis.

The unsatisfactory results of treatment of patients with complicated abdominal infection indicate the urgency of this problem and force us to look for new ways to solve it.

A known system consisting of a perforated cellophane film and a drainage-foam system irrigated with antiseptics and connected to an apparatus for active aspiration (RF patent No. 2164088 class. A61 B 17/00). After opening, eliminating the source of inflammation and sanitation of the abdominal cavity, the wound of the abdominal wall is delimited by a perforated cellophane film. To protect soft tissues from contact with exudate and intestinal event, a “shock absorber” is sewn, and a drainage-foam system is inserted into the abdominal cavity into the lower wound. Through lateral punctures, the ends of the outer vinyl chloride tubes are brought out, through which irrigation and outflow of exudate of the abdominal cavity are carried out.

This device has a number of significant disadvantages.

The use of antiseptic solutions for continuous irrigation of the abdominal cavity may be accompanied by toxic effects on the patient's body.

Sewing of the proposed system into the surgical wound occurs in a contaminated environment, accompanied by trauma to the abdominal wall, which contributes to its infection and the development of phlegmon.

The proposed system does not guarantee complete evacuation of fluid from the abdominal cavity, which contains a large number of biologically active substances and microorganisms that trigger and support the pathological process.

The objective of the utility model is a device with a higher suction ability.

The problem is solved by a device for active aspiration of fluid from the abdominal cavity, including soft drainage of 2 to 4 strips of hall-length 65-75 cm, a width of 5.0-6.0 cm and a thickness of 0.5-1.0 cm, laid crosswise and soldered into polyethylene with a perforation of 0.2 - 0.7 cm, with a frequency of 4-16 holes per dm ^, connected through a vinyl chloride tube to an apparatus for active aspiration.

Stages of use of the proposed device include:

1. elimination of the source of peritonitis and sanitation of the abdominal cavity;

2. preparation of sterile soft drainage;

3. placement of soft drainage in the abdominal cavity;

4. the formation of a drainage suction channel by introducing a vinyl vinyl drainage tube into the surgical wound;

5. sealing the abdominal cavity with a sterile film;

6. connection of the drainage tube with the apparatus for active aspiration;

7. setting up the suction system.

The figure shows the soft part of the drainage system.

Clinical example.

Patient M., 63 years old (source N5787), was admitted on 10/6/11 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. Gangrenous-perforated appendicitis with perforation at the base and abscess formation, 300 ml of pus was found in the abdominal cavity. 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. A soft drainage is imposed on the intestinal loops, consisting of 3 strips of hollcon 70 cm long, 6 cm wide and 1.0 cm thick, laid crosswise and soldered into polyethylene having perforations with a diameter of 0.5 cm with a frequency of 16 holes per dm ^. The edges of the soft drainage are immersed in the abdominal cavity: small pelvis, right and left lateral canals, subhepatic space. A large surgical tampon is placed on the soft part of the drainage, in which the intraperitoneal part of the vinyl chloride tube is inserted in the right mesogastrium through a 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. 10/07/2011, 24 hours after the initial intervention, performed program sanitation of the abdominal cavity. Soft drainage was removed from the abdominal cavity. The abdominal cavity is drained, sutured tightly. The postoperative period was uneventful. The wound healed by primary intention. On the 12th day the seams were removed. Patient M. was discharged for outpatient aftercare.

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