The invention relates to medical technology, namely to devices for spraying a powdered drug onto a pathological site.

A device for injecting powders is known, having contained its container for powders, closed on one side with an elongated tube, and on the other hand, a source of air pressure in the form of a rubber pear 1.

It is also known a device for spraying powdered substances, comprising a hermetic powder container made of an elastic material, inside which a tube is fixed, connected to the outlet 2.

The known devices are used for spraying medicinal powder on the walls of various cavity organs, but their design does not provide for the electrification of the sprayed powder, which is necessary, for example, for controlled application of the drug substance.

The closest technical solution to the present invention is an electrically charged medicinal drug dispenser; containing capacity connected to the spray tube through the hole, the active and indifferent electrodes located respectively inside and outside the spray tube 3.

The disadvantage of this sprayer is that it does not allow spraying and electrification of the powdery substance, as well as the directed introduction of the powdery preparation into the affected area.

The aim of the invention is to enable targeted spraying of a powdered preparation onto a pathology site in an electric field.

The goal is achieved by the fact that in an atomizer containing a container connected to the spray tube through an orifice, active and indifferent electrodes located respectively inside and outside of the spray tube the electrode is made in the form of a pointed rod and is located along the axis of the spray tube, connecting the spray tube with the container, at a distance of 1-2 the diameter of the active electrode, which in turn equals 0.25-0.5 of the internal diameter of the spray tube, and The differential electrode is connected to the additionally inserted electrode.

The drawing shows the structure of the proposed drug dispenser.

The drug dispenser contains a cylindrical glass container 1, which passes into the body at its base. There is a through hole 2 at the top of the cone. The container 1 is welded to the side wall of the glass spray tube 3 so that the hole 2 enters at a right angle into the channel 4 of the spray tube 3. The spray tube 3 is fixed in a die-type holder 5 material. In the channel 4 of the spray tube 3 there is an active electrode 6, which has the form of a pointed rod. The active electrode 6 is oriented along the axis

0 of the spray tube 3. The tip 7 of the active electrode 6 is located near the opening 2 of the container 1. The active electrode 6 is connected through a pushbutton switch with an electrical socket located in the handle of the holder 5. The pushbutton switch is turned on by pressing the key 8. Between capacity 1 and output end 9 of the spray tube 3 on its surface is fixed indifferent electrode 10, made in the form of a ring. The indifferent electrode 10 is connected with a wire to an electrical socket located in the handle of the holder 5. At the output end 9 of the spray pipe 3 a replaceable tip 11 is fixed. A powder preparation is filled into the container 1

5 12, after which it is tightly closed with a lid 13. Monopolar plugs 14 and 15 connected by wires to a source of constant high voltage are connected to the electrical sockets. On the outer surface of the patient's neck near the outbreak

A tuberculous lesion located on the trachea wall is attached to a plate electrode connected to a high constant voltage source.

The device works as follows.

In preparation for treatment, a well-dried anti-tuberculosis powdery preparation of fine consistency, such as rifadin, is poured into the sprayer container 1, after which the container 1 is tightly closed with a lid 13. The single-pole plugs 14 and 15 are connected to a high constant voltage source. The plate electrode and the indifferent electrode 10 are at the same potential and grounded.

The doctor, holding the nebulizer with his hand, inserts the tip 11 into the oral cavity of the patient, after which he presses key 8 with his index finger, while the active electrode 6 is connected to a source of high constant voltage.

Under the action of a high electric potential (15–20 KB) between the active 6 and indifferent 10 electrodes, a quiet discharge occurs, accompanied by an intense runoff of electrons and negative ions from the tip 7 of the active electrode 6, which is under negative potential. In their motion, the ions entrain air particles and form an electric wind. The movement of air through the channel 4 of the spray tube 3 leads to injection spraying of the powdered preparation 12. Fine particles of powder 12 entering through the opening 2 into the channel 4 under the action of electrons and negative ions flowing from the tip 7 of the active electrode 6, receive a negative charge and repel the tip 7. By an electric wind, the negatively charged powder particles are ejected through the tip 11 into the cavity of the patient’s mouth and are deposited in the pathology zone on the tracheal wall below the maximum with potential.

Practical use of the device allows the medicinal powder product to be delivered to the affected area economically, quickly and accurately, and thereby increases the effectiveness of the treatment.
