The invention relates to medical technology, namely to devices for the treatment of purulent and infected wounds with a pulsating stream of fluid, and can be used to prevent wound infection from implanted foreign particles and microorganisms in surgery, traumatology, dentistry and general sanitation.

The aim of the invention is to increase the efficiency of hygienic treatment of biological cavities by creating a pulse-impact effect.

FIG. 1 shows the irrigator, a general view; figure 2 - the case is installed inside a pulsator, a longitudinal section; on fig.Z - section aa in figure 2; in fig. A is an embodiment of a housing with an open end and an inner tube for suction of a liquid; FIG. 5 is a section A-A in FIG. 2. version of the housing with elements of mechanical cleaning

The irrigator contains a source of liquid under pressure with a flow or pressure controller, an elastic pipe 2 provided with an elastic receiver 3 with a variable capacity, and a perforated body 4 made cylindrical and equipped with a screw-fitting nipple 5 for connection with the elastic pipe 2. On the outer surface of the body 4 a scale of 6 is applied and a pointer 7 is mounted, connected with fitting 5. The outlet openings 8 are evenly spaced along the surface of the housing 4. Inside the housing 4 there is a pulsator, which is a spring 9 mounted coaxially with the housing 4. One part of the spring 9 has normally closed turns 10 and is fixed to the choke 5, while the cavity formed by the turns 10 is connected to the pipeline 2. The other part of the spring 9 has normally open turns 11 and is attached to the housing 4. Both parts are hermetically separated by a partition 12.

The housing 4 can be made closed from the end.

The housing 4 can be made with an open end and provided with an inner tube 13 connected to a vacuum suction and designed to suck the liquid from the cavity being treated.

The housing 4 may be provided with elements 14 of mechanical cleaning, for example, in the form of brushes.

Irrigator works as follows.

The antiseptic solution is poured into the source 1, the pressure is raised to the required level and the solution flow rate is set using the regulator. Screwing in the nozzle 5, they change the amount of compression of the normally open coils 11 of the spring 9, thereby accurately setting the oscillation frequency of the spring 9. The oscillation frequency is read using the scale 6 and the pointer 7

Then the housing 4 is introduced into the cavity to be treated and the pressure cutter of the source 1 of the fluid is opened under pressure

access of fluid through the elastic pipe 2 into the cavity formed by normally closed turns 10. Under the action of fluid pressure on the partition 12, normally open turns 11 begin

compress, and the normally closed turns 10 are expanded, while fluid under pressure penetrates into the cavity of the housing 4 and flows out through the holes 8. The pressure of the fluid on the partition 12

falls and the normally closed coils 10 are compressed again, the compartment supplying fluid. The pressure in the cavity formed by the normally closed turns 10 again increases and the cycle repeats again. Change volume

elastic receiver 3, a resonance in the system is achieved, which, with a slight initial pressure of the fluid in the source 1, allows for greater amplitude of oscillations of the spring 9 and increase

pulse impact efficiency.

In the presence of the inner tube 13 it is connected to a vacuum suction, providing simultaneous evacuation of waste

fluids from the treated cavity.

When processing the oral cavity, the mechanical cleaning elements 14, which can be provided with the housing 4, are used to mechanically clean the teeth.

The irrigator allows the treatment of wounds of any configuration, including deep bullet wounds, with frequencies from 0 to 1000 cycles per minute and more. At the same time, sharp jets are cut off, which gives the necessary pulsation frequency without concomitant oscillations with other frequencies, which increases the efficiency of processing tissues with a certain natural frequency. There is a sharp decline

dissemination of the wound to values of less critical, which allows immediately after treatment to sew up the wound without subsequent suppuration.
