Description

The utility model belongs to medicine, namely to medical technology, and can be used to create negative pressure in the framework of vacuum therapy of purulent wounds.

The use of drainage-vacuum systems is a modern and effective method of treating purulent wounds, as evidenced by numerous publications in the medical literature. The electric vacuum source is a rather expensive and difficult-to-access device, which forces many scientists to look for alternative options, however, the latter have a number of disadvantages that directly affect the treatment results.

The development of new, convenient, efficient and widely available vacuum source devices for drainage-vacuum systems will somewhat solve this problem.

Analogues of the useful model are well-known vacuum source devices for the drainage-vacuum system, which include: a plastic "accordion", a rubber "pear", a medical suction device (A.S.

Goncharov et al., 2003| etc.

The disadvantages of analog devices are the lack of counter pressure, the need to disconnect the drainage and vacuum system.

The prototype of a useful model is a source of vacuum for a drainage-vacuum system (Pat. 2163151 Russian Federation, MPK AbIM 25/01. Device for prolonged aspiration drainage / Huseynov A.G., Mutelimov M.M.; applicant and patent owner Aksionernoe Kurganskoe Obshchesti medicinikh preparatov и изделий "SINTEZ" - MO 2000107552/14; application: 03/27/2000; published: 02/20/2001 |, which consists of a single-use syringe, the piston of which has a transverse hole in its base, and a fragment of a Kirchner tip.

When using this device, the piston is inserted into the syringe body up to the resistance, which is connected to a silicone or plastic drainage tube that is hermetically connected to the wound cavity. Next, the syringe piston is pulled back, while creating negative pressure in the drainage system, until the appearance of the outer edge of the body of the last transverse hole at the base of the piston, into which a fragment of the Kirchner spit is inserted for the purpose of fixation. If the level of negative pressure is insufficient, then it can be doubled or tripled by pulling up the piston 2-3 times, but it is necessary to squeeze the polyvinyl chloride tube with a Kocher clamp between each action.

The disadvantage of the prototype method is the lack of control over the level of negative pressure, the need to disconnect the system when the syringe cavity is filled with wound exudate.

The useful model is based on the task of improving the source of vacuum for the drainage-vacuum system by the fact that the device consists of a container for collecting wound exudate with a port for connection to the drainage, a vacuum manometer, two mutually inverted gasoline non-return valves and a syringe connected polyvinyl chloride tubes.

Common features of the utility model and the prototype are that the device contains a syringe to create negative pressure.

The distinguishing features of a utility model from a prototype are that the device consists of a container for collecting wound exudate with a port for connection to a drain, from which a polyvinyl chloride tube is attached to which a vacuum manometer is attached (eg New Dry

Utility Vacuum Manometer Vic) for pressure control and after it a gasoline return valve (for example, from a VAZ 2108/2109/21099 car, manufactured at AVTOVAZ ODO, Tolyatti), which works to allow air to flow from this container, from which a polyvinyl chloride tube, mounted into another polyvinyl chloride tube, at the distal end of which a gasoline return valve is attached (for example, from a VAZ 2108/2109/21099 car, manufactured at AVTOVAZ

OO, Tolyatti), which works on passing air from a syringe, at the proximal end of which a syringe is attached to create negative pressure.

Definition of terms used when describing a useful model: vacuum source, drainage-vacuum system, container for collecting wound exudate, vacuum manometer, gasoline non-return valve, syringe.

Theoretical prerequisites for the implementation of a useful model.

The task of implementing a useful model was to develop a simple and affordable source of vacuum for the drainage-vacuum system, which would provide a controlled level of negative pressure, avoiding disconnection of the drainage-vacuum system.

A useful model is performed as follows.

The drawing shows the vacuum source for the drainage-vacuum system: 1 - syringe; 2 - container for collecting wound exudate; C - port for connection to the drain; 4 - gasoline check valve (from a VAZ 2108/2109/21099 car); 5 - vacuum pressure gauge (New Dry Utility

Vacuum Manometer Age); 6 - polyvinyl chloride tubes.

The device consists of a container for collecting wound exudate with a port for connection to the drain, from which a polyvinyl chloride tube leaves, to which a vacuum manometer (for example, New Dry Utility Vacuum Manometer Age) is attached to control the pressure, and after it a gasoline return valve (for example, from a car VAZ 2108/2109/21099, manufactured on

AVTOVAZ ODO, Tolyatti), which works on the air flow from this container, from which a polyvinyl chloride tube departs, mounted in another polyvinyl chloride tube, at the distal end of which a gasoline return valve is attached (for example, from a VAZ 2108/2109/21099 car, manufactured at AVTOVAZ ODAO, Tolyatti), which works on passing air from a syringe, at the proximal end of which a syringe is attached to create negative pressure.

Examples of the use of a useful model.

The port of the container for collecting wound exudate is connected to the drain, which is hermetically connected to the wound cavity. Pull back the piston of the syringe, while air enters the syringe from the container for collecting wound exudate through the gasoline non-return valve, which works to allow air to flow only in this direction and prevents further air from entering the container for collecting wound exudate. Next, the syringe piston is returned to its initial state, while the air escapes to the external environment through another gasoline return valve, which works to allow air to flow only in this direction and prevents air from the external environment from entering the system when the piston is pulled back.

Thus, pulling back and returning the syringe piston to its original state several times, create a vacuum in the drainage system, controlling the level of negative pressure with the help of a vacuum manometer.

Example. Patient Zh., born in 1961, on 26.02.2017, postoperative incomplete (subcutaneous) eversion occurred on the seventh day after surgical intervention (economic resection of the stomach) due to cancer of the antral part of the stomach, TzMeaMii, IM st., M cl. c. Gastrointestinal bleeding. After inserting the drainage tube between the skin seams into the pathological focus and creating hermetic conditions, the proposed device is attached. With the help of piston movements in the syringe, the appropriate level of negative pressure in the drainage system is created and maintained.

During the treatment, the tightness of the drainage system was maintained, the level of negative pressure was easily adjusted and monitored using a vacuum manometer.

Thus, the use of the proposed vacuum source device allows you to easily and conveniently create and control the level of negative pressure in the drainage-vacuum system, avoiding its disconnection.

Technical result. The proposed device allows you to effectively create a vacuum in the drainage-vacuum system, provides a controlled level of negative pressure, avoiding its disconnection.
