Description

one

The invention relates to medical technology and can be used for anesthesia during the operation of small operations and the provision of emergency medical care.

An inhaler is known that contains an evaporation chamber, a wick, a mouthpiece, inspiratory and expiratory classics.

However, such an inhaler has an unregulated limited area of evaporation of a narcotic substance, therefore, in many cases, the concentration of drug vapors is insufficient for autoanalgesia; in addition, it excludes the possibility of regulating the concentration of a mixture of several drugs against the background of the main one.

The aim of the invention is to make it possible to control the concentration of vapors of one or more liquid drugs in the inhaled mixture.

For this, in the proposed inhaler the evaporator chamber is made sectional and telescopic with sealing rings on each section.

The drawing schematically shows the proposed inhaler, a general view in section.

The inhaler contains mouthpieces 1, on which is located the regulator 2 of the concentration of drug vapors in the inhaled air, the valve 3 outlets and the clan 4 inlets. IN THE MANDTUDE

1, an evaporation section chamber is built in, the vypolpenpa of the individual chambers 5, 6 and 7, which are installed in series and located centered with respect to the evaporation chamber 5. Inside the chambers 6 and 7, respectively, sealing rings 8 and 9 are inserted, ensuring the tightness of the docking of the evaporation chambers. All chambers are fitted with wicks 10, 11 and 12, and the evaporation chamber 7 is closed by a lid 13.

Inhaler works as follows.

Sliding the chambers 5, 6 and 7 into one another, remove the flap 13. Holding the inhaler muid with the dipstick 1 down, fill the chamber 5 with the necessary drug so that the wick is soaked with it. Moving the chambers 6 and 7 in succession, pour the drug into them so that the wicks 11 and 12 are soaked in. If necessary, all evaporation chambers can be filled with the same drug or different to obtain the desired mixture of drugs that are inhaled by the patient. Since all the cameras are connected to one another with a mobile and concentric concentric, they are installed one relative to another at a certain distance corresponding to different areas of drug evaporation, achieve the required concentration of the drug vapor mixture. By varying the evaporation areas of the wicks 11 and 12, the co-concentration is controlled.

drug vapor mixtures. An increase in the concentration of drug vapors in the inhaled air mixture is achieved (as compared with single-chamber inhalers) due to a greater amount of evaporation in case of separated sections. The patient takes the mouthpiece 1 in his mouth and inhales the drug vapor, but after the necessary time has passed, analgesia occurs. If necessary, a mouthpiece 1 may be worn.

Claims (1)

4 claims An inhaler containing an evaporation chamber, a wick, a mouthpiece and inhalation and exhalation valves, characterized in that in order to control the concentration of vapors of one or several liquid drugs in the inhaled mixture, the evaporator chamber is made of sectional and telesconic suppression rings on each section.
