Изобретение относитс  к медицинской технике .The invention relates to medical technology.

Мзвестны дозаторы наркотических веществ, содержащие корпус, крыщку, емкость, входной и выходной щтуцеры и порщень.Drug dispensers are known that include a housing, a lid, a container, an inlet and an outlet, and a piston.

Однако они сложны но конструкции, не обеспечивают достаточно точной регулировки концентрации различных наркотических веществ и имеют большое сопротивление вдоху.However, they are complex but the designs do not provide sufficiently precise adjustment of the concentration of various narcotic substances and have a great breath resistance.

Предлагаемый дозатор, в котором указанные недостатки устранены, отличаетс  от известных тем, что он оснащен винтовой парой, щтифтом в виде фиксатора и указател  концентрации паров наркотических веществ, и направл ющими пазами, на обеих сторонах которых нанесены шкалы в соответствии с числом наркотических веществ.The proposed metering device, in which the indicated drawbacks are eliminated, differs from the known ones in that it is equipped with a screw pair, a clamp in the form of a lock and an indicator of the concentration of narcotic substances vapors, and guide slots, on both sides of which scales are plotted according to the number of narcotic substances.

На фиг. 1 схематично изображен предлагаемый дозатор, вид сбоку с частичным продольным разрезом и вид сверху; на фиг. 2 - схема перекрыти  входного и выходного штуцеров дозатора.FIG. 1 shows schematically the proposed dispenser, a side view with a partial longitudinal section and a top view; in fig. 2 is a diagram of the overlap of the inlet and outlet fittings of the dispenser.

Дозатор содержит корпус 1, поршень 2, винт 3, гайку 4 управлени , крыщку 5 п емкость 6.The dispenser includes a housing 1, a piston 2, a screw 3, a control nut 4, a cover 5 and a capacity 6.

На корпусе 1 размещены входной 7 и выходной 8 штуцеры. Поршень 2 выполнен в виде стакана с днии1.ем, расположенным в верхней части. На уровне днища порщень имеет кольцевые выточки, в которые устанавливаютс  унлотнительные кольца 9. Боковые On the housing 1 is placed inlet 7 and outlet 8 fittings. The piston 2 is made in the form of a glass with a dni1.em, located in the upper part. At the bottom level, the piston has annular recesses, into which the sealing rings 9 are installed.

поверхности порщн  имеют окна, совпадающие с входным и выходным отверсти ми корпуса. К днищу поршн  с помощью оси 10 прикреплен винт 3, который совместно с гайкой 4 управлени  образует винтовую пару. В верхней части корпуса расположена крыщка 5 с колпачком 11. Колпачок 11 на диаметрально противоиоложных концах имеет иродольные пазы 12, в которые входит щтнфт 13 с указателем 14. Штифт 13 закреплен в верхпей части винта 3 и служит одновременно фиксатором винта от вращательиого движеип . По кра м продольных пазов нанесены шкалы 15, которые проградунрованы в соответствии с концентрацией паров наркотиков на выходе из дозатора.The surfaces of the box have windows that coincide with the inlet and outlet openings of the housing. A screw 3 is attached to the bottom of the piston by means of an axis 10, which together with the control nut 4 forms a screw pair. In the upper part of the body there is a lid 5 with a cap 11. The cap 11 has diaphragm-free-end ends with Irodol grooves 12, in which the plug 13 with pointer 14 is inserted. The pin 13 is fixed in the upper part of the screw 3 and serves simultaneously as a screw lock from a rotating movement. Along the edges of the longitudinal grooves, scales 15 are applied, which are programed in accordance with the concentration of drug vapors at the dispenser outlet.

К нижней части корпуса 1 присоедннена емкость 6, в которую зал 1ваетс  наркотический препарат.A container 6 is connected to the lower part of the housing 1, into which the hall 1 is a narcotic drug.

Дозатор работает следующим образом.The dispenser works as follows.

Воздух из входного щтуцера 7 поступает во внутреннюю полость корпуса дозатора. При среднем ноложении поршн  2 одна часть воздуха проходит над днии-ieM, а друга  - поступает в полость насын1,ен11 , где смещнсаетс  с парами наркотика. На выходе из дозатора насыщенный воздух смешиваетс  с чистым воздухом, проход щим над днищем порщп , и поступает в зону дыханп  пациеита. В зависимости от положени  поршн  через зонуAir from the inlet fitting 7 enters the internal cavity of the dispenser housing. With the average position of the piston 2, one part of the air passes over the long-ieM, and the other part enters the cavity saturated, en11, where it is displaced with the vapors of the drug. At the outlet of the dispenser, saturated air is mixed with the clean air passing over the bottom of the gun and enters the breathing zone of the patient. Depending on the position of the piston through the zone

насыщени  может проходить больша  или меньша  часть воздуха (промежуточные положени ) или весь воздух (крайнее верхнее положение). При крайнем нижнем положении полость пасынденн  полностью перекрыта, и в зону дыхани  поступает только чистый воздух . Изменение положени  поршн  относительно окон производитс  враш,ением гайки 4 управлени . При этом винт 3 совершает поступательное движение вверх или вниз, и соответственно измен етс  положение поршн . Св занный с винтом штифт 13 и указатель 14 неремеш,аетс  по продольным пазам 12, занима  положение, соот1ветствуюш;ее определенному перекрытию окон, и указыва  концентрацию вдыхаемых паров наркотических препаратов .saturation can go through most or less of the air (intermediate positions) or all of the air (uppermost position). At the lowest position, the cavity of the passanden is completely blocked, and only clean air enters the breathing zone. Changing the position of the piston relative to the windows is made by turning the nut 4 on the steering wheel. In doing so, the screw 3 makes a forward movement up or down, and the position of the piston changes accordingly. The screw pin 13 and the pointer 14 are unmixed along the longitudinal grooves 12, occupying a position corresponding to its certain window overlap, and indicating the concentration of inhaled vapors of the narcotic drugs.

Предмет изобретени Subject invention

Дозатор наркотических веществ, содержащий корпус, крышку, емкость, входной и выходной штуцеры и поршень, отличающийс  тем, что, с целью повышени  точности регулировки концентрации различных наркотических вешеств, упрощени  конструкции и уменьшени  сопротивлени  вдоху, он оснащен винтовой парой, штифтом-фиксатором, указателем концентрации паров наркотических веществ, и направл ющими пазами, на обеих сторонах которых нанесены щкалы в соответствии с числом наркотических веществ.A dispenser of narcotic substances, comprising a housing, a lid, a container, inlet and outlet fittings and a piston, characterized in that, in order to improve the accuracy of adjusting the concentration of various narcotic substances, simplify the design and reduce inspiratory resistance, it is equipped with a screw pair, pin lock, pointer concentrations of vapors of narcotic substances, and guide slots, on both sides of which the scals are applied according to the number of narcotic substances.
