SU1250305A1 - Arrangement for treatment of wounds - Google Patents

Description

The invention relates to medical technology, in particular, to injection and aspiration apparatus used to clean wounds by washing away with antiseptic solutions and simultaneously sucking out tissue and exfoliated necrotic tissue.

The purpose of the invention is to prevent the spread of rejected masses over the wound surface and to reduce the trauma of the latter by creating in the zone of influence of a liquid-air mixture with a slip effect.

Fig, 1 shows the working part 5 of the socket, from where they enter the devices, a section; in fig. 2 - scheme of the tip.

The device for treating wounds contains a tip t with a central 2 and an additional 3 holes and a handle 4 with two channels 5, 6 for connecting the holes to a vacuum source and a tank for antiseptic pactBopa (not shown), respectively.

The tip 1 is hollow and has a socket fixed inside it, made in the form of a truncated cone. The Central hole 2 is made in the small base of the cone, additional holes 3 in the conical part, the axes of which are directed at an angle to the longitudinal axis, and the cross section of the central hole 2 exceeds the sum of the sections of the additional holes 3.

The device is used as follows.

Channel 5 is connected to a vacuum source, and channel 6 is connected to a tank for

antiseptic solution. The tip 1 is brought to the surface to be cleaned, after contact of the socket 7 seconds, the surface to be cleaned and the exfoliated necrotic tissues begin to be sucked under the influence of vacuum.

At the same time, through channel 6 of the above container, an antiseptic solution is injected into the cavity of tip 1, which is injected through the socket 3 into the mouth of 7. The antiseptic pacTBop.d streams wash the wound surface and collect in the center

5. By moving the tip along the plane of the wound surface, the entire area of the wound is sequentially processed.

During the treatment of the wound, conditions are created for the ejection of ambient air into the mouth of the socket 7 with the formation of a liquid-air mixture at the same time, facilitating the leaching of the separated,

In this case, the air intake is provided by the difference in cross sections of the central 2 and additional 3 holes of the socket 7.

Constructive execution, the tip of the proposed device provides a sliding effect of the liquid-air mixture, which provides atraumatic spade and its movement over the entire wound surface and prevents the spread of rejected masses.

By making the tip replaceable. With various designs, various wound surfaces of patients can be treated.
