1one
Изобретение относитс к медицине кой технике и может быть использовано при дозировании малых объемов реагентов и биожидкостей в клинико-диагностических лаборатори х.The invention relates to medicine and can be used in the dosing of small volumes of reagents and biofluids in clinical diagnostic laboratories x.
Известно устройство дл дозировани жидкостей, состо щее из поршневого дозатора, в корпусе которого смонтированы гильза и клапан, приспособлени дл регулировани дозы и гильза и клапан, приспособлени дл регулировани дозы и емкости дл жидкоети 1 .A device for metering liquids is known, consisting of a piston metering device, in the case of which a sleeve and a valve are mounted, dose adjustment devices and a sleeve and a valve, dose adjustment devices and a liquid network container 1.
Недостатком известного устройства вл етс то, что в нем имеетс два уплотнени , что увеличивает веро тность утечки жидкости и создает дополнительное сопротивление при перемещении поршн .A disadvantage of the known device is that it has two seals, which increases the likelihood of fluid leakage and creates additional resistance when the piston is moved.
Цель изобретени - повышение надежности в работе путем предотвращени утечки жидкости.The purpose of the invention is to increase operational reliability by preventing fluid leakage.
Поставленна цель достигаетс тем, что в устройстве, состо щем из поршневого дозатора, в корпусе которого смонтированы гильза и клапан, приспособлени дл регулировани дозы и емкости дл жидкости, внутренн поверхность гильзы в верхней части выполнена конической, а по ее окружности образованы прюрези дл прохода жидкости, клапан представл ет собой трубку, нижний конец которой имеет форму конуса дл входа в коническую часть гильзы, а верхний - в виде ниппел , при этом над последним установлена втулка с отверсти ми дл прохода жидкости к прорез м гильзы.The goal is achieved by the fact that in a device consisting of a piston metering device, in the case of which a sleeve and a valve are mounted, devices for adjusting the dose and a container for a liquid, the inner surface of the sleeve in the upper part is made conical, and around its circumference there are holes for the passage of liquid. , the valve is a tube, the lower end of which has the shape of a cone for entry into the conical part of the sleeve, and the upper end is in the form of a nipple, with a sleeve with openings for the passage of fluid above the latter and to the slot m liner.
