Description

 The invention relates to devices for administering drugs to the body, in particular to the sinuses, auditory tubes, tympanic cavities.

 Known devices for introducing liquid drugs into the sinuses (Markov GI Kozlov VS and Mazetov GS Journal of ear, nose and throat diseases, 1984, N 5, p. 81-84. Methodology for the use of antibiotics by "displacement" for the treatment of patients with inflammation of the sinuses. Rostov-on-Don: Medicine, 1965, p. 4-6). These devices are not intended to introduce aerosols into the auditory tubes, tympanic cavities and / or paranasal sinuses. There are aerosol devices (Big Medical Encyclopedia, 2, p. 420-426), which do not provide sufficient introduction of aerosols into the auditory tubes, tympanic cavities and / or sinuses. Methods for administering drugs to the auditory tubes, tympanic cavities using catheters are described, however, these methods are traumatic, since the introduction of catheters into the auditory tubes may damage their mucous membrane with subsequent formation of adhesions (Journal of Ear, Nose and Throat Diseases, 1987, N1, p. 83-84).

 There is a method of introducing drugs into the sinuses, which describes a device containing a device for hermetic attachment to the nose, made in the form of an "olive" for hermetic attachment to one of the nostrils, communicated using elastic tubes with devices for hermetic attachment to the external auditory passageways. The method includes a pressure differential between the nasal cavity and sinuses. After the drug is introduced into the nose, the external auditory canals and nostrils are hermetically connected, and after a deep breath with closed lips and muscle tension covering the larynx opening, synchronous lowering and raising of the lower jaw and larynx are carried out alternately with effort.

 The disadvantages of the method and device are: the possibility of patients exceeding the pressure in the nasal cavity, sufficient to administer drugs to the paranasal sinuses, as a result of which the injected drugs, mucus, pus can penetrate the auditory tubes, tympanic cavities, etc. in addition, there is no possibility of introducing aerosols into the auditory pipes, drum cavities.

 A device is known (US patent N 4919128, class A 61 M 15/00 1990, John A. Kopala, John E. Remmers) containing a device for tight connection to the nose, made in the form of two displaceable relative to each other devices for tight connection to one of the nostrils with "olive-shaped" outer surfaces. The device is designed to deliver gases to the respiratory tract.

 The technical task of the invention was to develop a device that allows you to enter drugs / aerosols, fluids / into the auditory tubes, tympanic cavities and / or sinuses, as well as preventing the excess of a given positive and / or negative pressure in the nasal cavity, prescribed by the doctor individually for each patient .

 The technical result consists in the introduction of aerosols or fluids into the auditory tubes, tympanic cavities and / or paranasal sinuses, in preventing exceeding a predetermined positive and / or negative pressure in the nasal cavity prescribed by the doctor.

 The objective is achieved in that the device for introducing aerosols into the paranasal sinuses, tympanic cavities contains a device for tight connection to the nose. New is that it is equipped with a pressure regulator in communication with a device for tight connection to the nose.

 The device for tight connection to the nose is made in the form of one or two "olives", providing a tight connection to one or two nostrils.

 The pressure regulator is made in the form of an adjustable valve for supplying aerosols to the device for tight connection to the nose.

 The pressure regulator is designed as an adjustable valve to reduce overpressure.

 The pressure regulator is configured to connect to an aerosol device.

 The device has a device for holding it tightly to the nostrils.

 The specified set of essential features in the first paragraph of the claims is necessary to achieve the specified technical result, since the presence of a pressure regulator in communication with the device for hermetic attachment to the nose allows, in particular, the "Method of introducing drugs into the sinuses" / cm. above /, since when the patient independently creates a negative pressure in the nasal cavity and exceeds this pressure of the set pressure, the air / aerosol / pressure regulator is sucked through the pressure regulator and a device for tightly connecting the nose into the nasal cavity and then, when carrying out the above method, into the sinuses and / or in the auditory tubes, tympanic cavities / with open external auditory canals /, and when positive pressure in the nasal cavity is exceeded and the device for tight connection When the preset pressure is applied to the nose, the air regulator leaves the nasal cavity and devices for tight connection to the nose through the pressure regulator to the external environment. The procedures can be carried out without the patient’s forced position while draining and administering drugs to the auditory tubes, tympanic cavities and / or paranasal sinuses. The pressure regulator is set pressure parameters that are safe for the patient and sufficient for the purpose set for the procedure.

 The pressure regulator in the specific form of the device is made in the form of an adjustable valve for supplying aerosols / air / to the device for tight connection to one of the nostrils "olive" (and can be made with the possibility of connection to the aerosol device) and an adjustable valve to reduce the excess pressure to another "olive". When carrying out, in particular, the above method, the aerosol is supplied to the nasal cavity through one "olive", and through the other "olive", the air leaves the nasal cavity through the pressure regulator to the external environment / when the pressure set by the adjustable valve is exceeded to reduce the excess pressure / . In other cases, both valves can be connected to one of the “olives”, and the other “olive” to an electric suction pump, etc., or for introducing aerosols, liquids into the auditory tubes, paranasal sinuses, only a valve can be used to reduce overpressure, etc. specific forms of the device’s existence, the pressure regulator can be made in the form of a tube with a narrow section, which can be adjustable, or in the form of a sealed container with elastic walls and a certain shape, or in the form of a combination of various similar elements, etc.

 A device for tight connection to the nose can be presented in the form of one "olive", two "olives", a mask for tight connection to the external nose, etc.

 The drawing shows a diagram of a device for introducing aerosols and fluids into the paranasal sinuses, tympanic cavities.

 The device comprises a device 1 for tight connection to the nose / made in the form of two "olives" /. One of the "olive" is connected with an adjustable valve 2 for supplying aerosols to the device 1, and the other "olive" is connected with an adjustable valve 3 to reduce excess pressure. The adjustable valve 2 is configured to connect to an aerosol device (not shown) in the form of a nozzle 4. The device has a device 5 for holding it tightly to the nostrils.

 The device operates as follows.

 With the introduction of liquid drugs into the sinuses, the doctor sets certain pressure parameters for the pressure regulator / valves 2, 3 /. The patient in a supine position with his head thrown back injects medicine into the nose, takes a breath, attaches the “olives” 1 hermetically to the nostrils with the help of device 5, closes the external auditory canals, closes the lips, strains the muscles covering the larynx opening, and alternates with effort synchronous lowering and lifting of the lower jaw and larynx. When carrying out the above variant of the introduction of liquid drugs into the paranasal sinuses, the adjustable valves 2,3 prevent the patient from inadvertently exceeding the preset pressure in the nasal cavity and exclude complications from the ears.

 With the introduction of aerosols in the paranasal sinuses, the procedure can be carried out similarly to that described above with the additional connection of the nozzle 4 to the aerosol device, in addition, the patient does not take a forced position.

 With the introduction of drugs into the auditory tubes, the tympanic cavity of the procedure is the same / cm. above / but without closing the external auditory canals or without communicating them with the nose.
