(54) DEVICE FOR THE INTRODUCTION OF MEDICINAL

one

The invention relates to medical technology and can be used to inject drugs into the sinuses of the nose.

A device is known that allows liquid drugs to be introduced into the paranasal sinuses by the " displacement method developed by Proetch containing a hand vacuum pump connected by a flexible hose with a tip. Drug administration is carried out as follows: after pretreatment of the nasal passages of the locus to enlarge the inlet openings of the paranasal sinuses, the patient lies on his back, with his head thrown back sharply. A solution of drugs is poured into the patient's nostrils and, tightly pressing one nostril, the air is pumped out. from the second pump. Under the action of the resulting discharge, the drug solution is transferred to the paranasal sinuses.

The disadvantages of this device are significant patient pain when fluid enters the parenchymal preparations.

zuhi; the uneven distribution of the administered medications both in the sinuses and in their area; the need to find a patient with a sharply thrown back head for a long time,

5 that may be a contraindication for the method of "moving the elderly and those suffering from pain or dizziness.

The purpose of the invention - the reduction of pain

) 0 sensations by alternately creating a vacuum and introducing drug vapors into the sinuses.

The goal is achieved by the fact that a device for administering drugs containing a vacuum

15, the pump, with a hose, is equipped with a liquid collection vessel, a pressure sensor, an additional hose for supplying the mixture, two electric pneumatic valves, a spray chamber, and a control unit. a pulse counter 20, the pressure sensor input is connected to the vacuum pump outlet, and the output is connected to the first inputs of the pulse counter and the control unit, the input of the liquid collection vessel through the first electric air valve is connected to the tip, and the control input of the first electric air valve is connected to the first output of the control unit the second outlet of which is connected to a vacuum pump and a second electropneumatic valve, located between the spray chamber and n, tip.

At the same time, the pump hose and the additional hose are placed in the same handpiece.

The drawing shows a block diagram of the device.

The device contains a vacuum pump 1, a pressure sensor 2 with an electrical outlet, a liquid collection vessel 3, a hose 4, a hose 5, electropneumatic valves 6 and 7, a tip 8, a spray chamber 9, a control unit 10, a pulse counter 11

The device works in the following way.

The tip 8 is tightly inserted into the patient's nostril, while the second nostril is covered with a finger. After pressing the Start button, the control circuit signals set the pulse counter 11 to the zero state, and also open the valve 6, close the valve 7, and turn on the vacuum pump 1, which, through the hose 4, creates a vacuum in the nose and 9 COLON spaces. When the pressure in these cavities decreases to a predetermined value, the signal from the pressure sensor 2 enters the control unit 10, which causes the vacuum pump 1 to turn off, valve 6 to close and valve 7 to open. Under the effect of the difference between the atmospheric pressure of the nasal cavities drug from the spray chamber 9 in the nasal and paranasal cavities. When the pressures are equalized, the supply of the drug is stopped, and after holding for 8-10 seconds, which is necessary to precipitate the drug particles on the walls of the sinuses, the signals of the control unit 10 cause the cycle to repeat. For convenience of dosing, the number of injections is counted by a pulse counter 11 and displayed on a digital display. When dispensing medicines in other ways, the pulse counter 11 can be excluded.

The use of new elements in the proposed device — a spray chamber, an additional hose, electropneumatic valves, a pressure sensor, and a control unit — reduces the patient's painful sensations arising from the delivery of liquid medicines into the paranasal sinuses using a known device. The use of the proposed device frees the patient from having to be with his head thrown back for a considerable time.
