Cryogenic Liquid Nitrogen LN2 Sprayer Freeze Treatment Instrument 500ml 16oz. DZ-4 low temperature liquid nitrogen container is a small handheld cryogenic container. It can be applied to dermatology, ophthalmology, ENT, anal and so on with appropriate cold head. The DZ-4 low-temperature liquid nitrogen container is cooled by liquid nitrogen as a cold source.
The liquid nitrogen is in a closed liquid storage bottle, and the liquid vapor is naturally evaporated and vaporized to raise the liquid in the liquid storage bottle into a certain pressure. Under the action of pressure, the liquid nitrogen passes through the cold head from the infusion tube (the gasification is intensified in the cold head, and the gas and liquid are discharged from the exhaust pipe).
The cold head forms a cold field under the action of low temperature of liquid nitrogen, and will be cold when used. The head is selected to the appropriate temperature and is exposed to the diseased skin. Under the action of low temperature, the diseased cells are killed and naturally shed to achieve a cosmetic effect. 1: The liquid storage bottle is made of 500 ml slender cup, and the shell is made of double-layer stainless steel and vacuum-polarized. 2: Cold guns, barrels, infusion tubes, exhaust pipes, etc.Are made of small-diameter thin-walled stainless steel seamless tubes. 3: The cold head is made of pure copper with good thermal conductivity, and the surface is silver-plated. 4: Handle is made of plexiglass. 5: The instrument case is made of leather case, the inner material of the box is made of wood, the box lock and the handle are beautiful and convenient to use. (1) Reasonable structure and fine workmanship.
(4) Beautiful appearance and novel style. Open the upper cover of the therapeutic device, fill the liquid nitrogen, tighten, install the selected cold head, open (tighten) the control valve, and spray liquid nitrogen without leakage.Note: Check the gasket of the lid and the cold treatment tip before use, otherwise it will leak. 1 Wipe the instrument clean before use. 2 When liquid nitrogen is added to the liquid storage bottle, it is not necessary to pre-cool, the filling speed is slower, and the filling liquid nitrogen should not be too full (preferably not more than 400 ml). 3 Quickly cover the top cover and lock the threaded ferrule. 4 Close the switch of the control valve by hand, and the exhaust pipe starts to spray out the gas and liquid.
6 When not in use, the instrument should be placed in the instrument box to save or choose the location. The liquid nitrogen in the liquid storage bottle should be disposed of beforehand.7 Pay attention to the purity of liquid nitrogen in the liquid storage bottle to avoid clogging the infusion tube and the exhaust pipe (if there is a blockage, the thin steel wire can be used inside the pipe). 8 Strictly prevent impact and collision, in order to prevent damage to the cup body, which will cause air leakage and affect the use. 9 If the shell of the liquid storage bottle has water drops or hoarfrost on it, it proves that the vacuum of the cup has deteriorated (it will cause air leakage).
