Description
отводна упруга трубка 4 длиной 8-9 см и диаметром 1,5 мм.The elastic tube 4 is 8–9 cm long and 1.5 mm in diameter.
Устройство работает следующим образом .The device works as follows.
На узкогорлый сосуд или на вскрытую ампулу 1 со стандартной сывороткой плотно надевают колпачок 2 с проход щей через отверстие 3 упругой отводной трубкой 4, внутренний конец которой погружен в сосуд или ампулу до дна. .При сжимании пальцами колпачка 2 вследствие избыточноI го давлени , создаваемого при этом в сосуде (ампуле), содержимое ее по капл м свободно вытейает через наружный конец трубки . С прекращением компрессии колпачок 2 расправл етс и воздух засасываетс в ампулу 1 через трубку А, как бы зар жа устройство дл повторного извлечени жидкости при последующем нажатии на колпачок.A cap 2 with a resilient discharge tube 4 passing through the opening 3, the inner end of which is immersed in the vessel or ampoule to the bottom, is tightly put on the narrow-neck vessel or on the opened ampoule 1 with standard serum. When the cap 2 is squeezed with fingers, due to the overpressure created in this case in the vessel (ampoule), its contents drop out dropwise through the outer end of the tube. With the termination of the compression, the cap 2 expands and the air is sucked into the ampoule 1 through the tube A, as if charging a device for re-extracting the fluid when the cap is subsequently pressed.
Предлагаемое устройство просто в изготовлении, удобно в обращении, ускор ет и облегчает манипул ции по забору сыворотки из ампулы. Кроме того , оно позвол ет дозировать в капл х , измен соответственно степень компрессии колпачка, объем извлекаемой из ампулы сыворотки, экономит The proposed device is easy to manufacture, it is easy to handle, it accelerates and facilitates manipulation of the collection of serum from the ampoule. In addition, it allows dosing in drops, changing the degree of cap compression, the volume of serum extracted from the ampoule, saves
расход сыворотки, предохран ет ее от высыхани и, что крайне важно, не требует переливани сыворотки в специальные емкости. Простота и дешевизна устройства делают его доступным дл любой лаборатории или лечебного учреждени .the consumption of serum prevents it from drying out and, which is extremely important, does not require the transfusion of serum into special containers. The simplicity and low cost of the device make it available to any laboratory or medical institution.
