Abstract

The utility model relates to the field of medicine and medical technology, namely, devices designed for vacuum drainage of wounds using alternating negative pressure, can be used in the treatment of purulent wounds, including in thoracic surgery in patients who have performed sternotomy. vacuum drainage of wounds using a device that consists of a hermetic wound dressing connected to a container for collecting wound and a source of vacuum (creating th alternating negative pressure) through the port of the vacuum wire. Pre-vacuum wire is placed in the thickness of the porous sponge. The porous sponge is covered on all sides by a film of synthetic material, which is perforated with a 21 G injection needle over the entire length, 6 to 9 holes are applied per 1 cm. The location of the vacuum wire in the thickness of the porous sponge provides uniform, more effective drainage of the wound, covering the porous sponge with a film of synthetic material protects it from germination by granulation tissue and eliminating the risk of bleeding when removing the sponge.

Description

The utility model relates to the field of medicine and medical technology, namely, devices designed for vacuum drainage of wounds using alternating negative pressure, can be used in the treatment of purulent wounds, including in thoracic surgery in patients who underwent sternotomy.

In patients after surgical interventions on the heart by sternotomy, threatening postoperative complications are sternomediastinitis, suppuration of the wound, the development of which significantly aggravates the course of the underlying disease, lengthens the patient's hospital stay, increases the cost of treatment, often causes deaths and negatively affects the recovery time of the operated sick.

Currently, vacuum drainage, which positively improves the course of the wound healing process, is widely used for the treatment of wounds, as numerous publications on this topic prove. Despite the significant effectiveness of this method, it also has negative aspects. The wound walls surrounding the applied sponge grow into it with granulation tissue, bleeding may occur when the sponge is removed. Vacuum drainage of wounds using alternating negative pressure in the treatment of sternomediastinitis can contribute to infectious arrosion of the myocardial wall, which leads to sudden massive bleeding and death.

At the moment, various medical devices manufactured by the medical industry are used for vacuum therapy.

A known system for vacuum treatment of wounds "Vivano NPWT System" ("HARTMANN" Germany), taken as a prototype. This installation consists of an aspirator, which is connected to a hermetic wound dressing using a connecting port, which is fixed to the container for collecting exudate, a sponge (VivanoMed) made of hydrophobic polyurethane.

A disadvantage of the known system for vacuum therapy of purulent wounds is that the applied sponge sprouts granulation tissue, bleeding may occur when the sponge is removed. Negative pressure in the wound is carried out through a port connected to an airtight wound dressing, the hole of this port is located at the top of the wound, so the exudation is not uniform.

A known system for vacuum therapy of wounds, taken as a prototype (Patent for utility model No. 174957 publ. 11/13/2017 Bull. No. 32). The main objective of this utility model is to ensure that the patient is safe for conducting vacuum drainage of wounds and to reduce the risk of complications. This is achieved by the fact that the device consists of a coating material that covers the vicinity of the wound and a porous pad connected to a container for collecting wound and a vacuum source (creating alternating negative pressure) through a vacuum wire port, which is a non-collapsing hollow tube. The porous patch has a corrugated surface in its lower part, which allows the patch to change its configuration for a specific wound defect. The disadvantage of this utility model for vacuum therapy of purulent wounds is that the applied sponge sprouts granulation tissue, bleeding may occur when the sponge is removed. Negative pressure in the wound is carried out through a port connected to an airtight wound dressing, the hole of this port is located at the top of the wound, so the exudation is not uniform.

The objective of the invention is to provide a system for vacuum therapy of wounds, including in thoracic surgery in patients who have performed sternotomy, providing a technical result, consisting in the fact that effective vacuum drainage of wounds is carried out using a device that consists of a tight wound dressing, connected to the container for collecting wound and a source of vacuum (creating alternating negative pressure) through the port of the vacuum wire. Pre-vacuum wire is placed in the thickness of the porous sponge. The porous sponge is covered on all sides by a film of synthetic material, which is perforated with a 21 G injection needle throughout, from 6 to 9 holes are applied per cm 2 . The location of the vacuum wire in the thickness of the porous sponge provides uniform, more effective drainage of the wound, covering the porous sponge with a film of synthetic material protects it from germination by granulation tissue and eliminating the risk of bleeding when removing the sponge. The perforated surface of the film retains the adhesive properties of the sponge.

The invention is illustrated in FIG. one

FIG. 1 illustrates the device and the vacuum drainage of a wound:

1 - wound

2 - porous sponge,

3 - vacuum wire,

4 - side holes on the vacuum wire,

5 - a film of synthetic material,

6 - holes on the film of synthetic material,

7 - coating material hermetically covering the wound,

8 - container for collecting wound

9 - a source of vacuum

The utility model is used as follows.

In the treatment of purulent wounds, including in thoracic surgery in patients who underwent sternotomy.

To carry out vacuum drainage, the wound 1 is treated, then a device is assembled for this; the thickness of the porous sponge 2 is introduced using a trocar along its entire length, the vacuum wire 3, which has side holes 4 with a diameter of 0.3-0.5 cm, located only in part of the vacuum wire 3 introduced into the sponge, the sponge is covered with a film 5 of synthetic material, which is perforated with a 21 G injection needle, 6 to 9 holes 6 are applied per cm 2 , then the device is installed in the wound 1 and the wound is sealed with a covering material 7 in the akum wire 3 passing through the covering material is connected to the container 8 to collect the wound and the source of vacuum 9.

The positive effect of the claimed technical solution is to ensure uniform, more effective drainage of the wound, the absence of sprouting granulation tissue of the sponge eliminates the risk of bleeding.

Clinical example.

Patient K., 56 years old, with a diagnosis of separation of the chords of the posterior cusp of the mitral valve of traumatic origin. Mitral insufficiency of 4 degrees. Pronounced dilatation of the heart chambers. Relative tricuspid insufficiency of 2 degrees. Pulmonary hypertension. CHF-2A.

Performed: median sternotomy, mitral valve prosthetics with a MedInzh-2 mechanical prosthesis No. 29, annuloplasty of the tricuspid valve according to De-Vega under conditions of cardiopulmonary bypass and pharmacological cold cardioplegia.

Complications: Sluggish postoperative mediastinitis. Partial failure of the integrity of the sternum.

Conducted vacuum drainage of the wound. The device was assembled, for this purpose, a vacuum wire was introduced into the thickness of the porous sponge using a trocar, which has side holes with a diameter of 0.3 cm, located only in the part of the vacuum wire introduced into the sponge, the sponge was covered with a film of synthetic material, which perforated with a 21 G injection needle all over, up to 9 holes were applied per 1 cm 2 , then the device was inserted into the wound and the wound was sealed with a covering material, a vacuum wire passing through the covering material was connected to a wound collection container detachable and vacuum source.

The wound cleared on the 5th day, secondary sutures were applied.

Thus, the proposed device provides a uniform, more effective drainage of the wound, the absence of germination of granulation tissue sponge eliminates the risk of bleeding.
