Abstract

Zariadenie na liečbu otvorených poskočení tkaniv. Vynález patří do odboru lekárskych zariadení a rieši zariadenie na liečbu otvorených poskočení tkaniv. Jeho podstata je v tom, že na vstupný otvor izolačného vaku je sterilnou hadičkou připojený bakteriálny filter so sterilnou filtračnou látkou, pričom na vstupnú časť bakteriálneho filtra je připojený regulačný ventil, na ktorý je připojený jednak tlakový vzduchový zdroj a jednak kyslíkový zdroj. Vynález je znázorněný na obr.Device for the treatment of open tissue spurs. The invention belongs to the field of medical devices and solves a device for the treatment of open tissue spurs. Its essence is that a bacterial filter with a sterile filter material is connected to the inlet opening of the isolation bag by a sterile tube, while a control valve is connected to the inlet part of the bacterial filter, to which both a pressurized air source and an oxygen source are connected. The invention is shown in Fig.

Description

The invention belongs to the Department of Medical Devices and addresses a device for treating open tissue damage. The essence of this is that a bacterial filter with a sterile filter substance is attached to the inlet opening of the insulating bag by a sterile tubing, and a control valve is connected to the inlet portion of the bacterial filter, to which is connected both a pressure air source and an oxygen source. The invention is illustrated in FIG.

The present invention relates to an apparatus for treating open tissue damage providing a sterile oxygen-rich environment in the vicinity of tissue damage, particularly associated with open fractures, without the use of dressings and dressings.

To date, the treatment of open fractures and other open tissue defects has been done with conventional cover and dressing materials. The wound after such treatment did not have enough oxygen, which at the repair stage requires even more than normal, actually the tissues were irritated by the covering and dressing material and the freshly formed epithelium, which is essentially one layer of newly formed epithelial cells at the early healing stage the bandages were torn down and the healing process was prolonged. Similarly, the risk of infection was high in this treatment, and secondary infectious complications occurred many times. Recently, such devices have emerged that have been able to produce an abacterial and sterile environment around the tissue defect. However, they did not solve the problem of the increased need for oxygen in the repair processes that take place in the early healing process.

This drawback is eliminated by the device according to the invention, which is based on the fact that a bacterial filter with a sterile filter substance is attached to the inlet opening of the insulating bag by means of a sterile tubing, and a pressure gauge control valve is connected to the inlet portion of the bacterial filter. and an oxygen source. The advantages of the device according to the invention are in the use of an oxygen-air mixture in the ratio of 1: 2.5 as sterile microclimate in an insulating bag, which accelerates the reparative processes occurring in the early, thereby reducing the time of treatment of the tissue defect and substantially reducing the risk of infection.

SUBJECT

Device for treating open tissue damage, in particular associated with open fractures, without the use of cover materials, characterized in that a bacterial filter (4) is connected to the inlet opening (8) of the insulating bag (7) by a sterile tubing (6).

The attached drawing is a schematic drawing of an embodiment of an apparatus for treating open tissue defects.

A bacterial filter 4 with a sterile filter medium 5 is connected to the inlet 8 of the insulating bag 7 by a sterile tubing 6 and a control valve 2 with a pressure gauge is connected to the inlet part 9 of the bacterial filter 4 to which a pressure air source 1 and an oxygen source are connected. third

A pressure-supply air source 1 and an oxygen source 3 are connected to a control valve 2 with a pressure gauge. From the control valve 2, an oxygen-air mixture in a ratio of 1: 2.5 is supplied at an overpressure of about 1 kPa relative to atmospheric pressure. 4 filled with a sterile filter substance 5, which may be, for example, sterile cellulose wadding, after passing through which it has already been cleared of microorganisms through a sterile tubing 6 into an insulating bag 7, where it creates a sterile oxygen-rich environment.

The device according to the invention is useful in traumatology, orthopedics and surgery for the treatment of tissue defects while preventing nosocomial infections. It is applicable both to traumatic tissue damage, such as open fractures, burns, extensive tissue devastation, etc., as well as orthopedics and surgery as a preventive measure during convalescence! after operations. Advantages of this device include ease of portability, small size and material ease of use It can be used under conditions of central oxygen distribution hospitals using compressed air and oxygen cylinders or compressor and compressed oxygen cylinders.

OF THE INVENTION with a sterile filter medium (5), wherein a control valve (2J) is connected to the inlet part (9 J of the bacterial filter (4), to which a pressure air source (1) and an oxygen source (3) are connected.
