Today's balcony windows have grown from original wooden windows, steel windows, and aluminum alloy windows to color aluminum windows. The current new color aluminum window has new development regardless of the material and style of the window. The appearance is neat and beautiful. It has good functions such as wind and rain, dust and noise protection. In addition to the normal push and pull and side opening There are also new ways to open the upper suspension, push and pull the upper suspension, etc., so that the balcony can be more "intimate contact" with the outdoor space when the window is opened. Color aluminum windows are widely appreciated by users for their excellent characteristics. When selecting color aluminum windows, attention should be paid to the identification of the following matters: First: materials The main materials of color aluminum windows generally include three aspects: aluminum profiles, glass, and hardware. Owners often pay more attention to the thickness of aluminum profiles and glass when purchasing products, but the requirements for hardware are not very high, which is not comprehensive. In fact, the state has certain standards for color aluminum windows. The thickness, strength and oxide film of the aluminum profiles used for high-quality color aluminum windows can generally meet the national standards. For example, the relevant national regulations require: The thickness of the aluminum profiles of color aluminum windows should be no less than 1.2mm, The thickness should reach 10 microns. Tempered glass is better than ordinary glass, if you consider the safety and durability of doors and windows, stainless steel hardware accessories (such as screws, hinges, handles, etc.) are better than aluminum accessories, and the best choice for pulleys is the use of POM materials Because such products have higher strength and wear resistance, they are smooth and not easy to be damaged during use. You know, the damage of doors and windows usually starts from the accessories of doors and windows! Second: processing With good materials, the next step is the processing of doors and windows. Because the technical content of color aluminum windows is not high, and the degree of mechanization is not high at present, most of them also rely on the manual operation of the installation workers, which requires the operators to have a good sense of product quality. It is very important to strengthen the proficiency of operators and product awareness in the production process. High-quality color aluminum window, fine processing, smooth tangent, and consistent angle (main frame material is usually 45 degrees or 90 degrees), there should be no obvious gaps during the splicing process, good sealing performance, and smooth switching. Inferior color aluminum windows, especially for frameless balcony windows, if the processing is unqualified, there will be problems with the sealing nature. Not only does the air leak and rain, but also the glass will burst and fall off under the action of strong winds and large external forces. Thereby causing property owners to lose property or even hurt people. Third: Appearance Owners purchase color aluminum window products, usually paying attention to the appearance of the product and the decorative patterns of the glass, and often underestimate the composite film on the surface of the color aluminum window. This composite film is formed by artificial oxidation film coloring, which is corrosion-resistant and wear-resistant Damage, high gloss, and also has a certain fire protection function, so when buying aluminum alloy doors and windows products, compare more similar products. The art of glasswork varies from person to person, and different owners choose according to their own preferences. The price of color aluminum windows is directly related to the price of aluminum ingots, but generally the price of color aluminum windows in a certain period of time is relatively stable. In general, the price of high-quality color aluminum windows is lower than that of inferior colors. Aluminum window products are 30% higher. Inferior color aluminum windows usually use extruded aluminum profiles containing a large amount of impurities. The aluminum profiles used have wall thicknesses of only 0.6-0.8 mm, both in terms of tensile strength and yield. Much lower than the relevant national regulations, this type of colored aluminum windows, especially frameless balcony windows, are very unsafe, so the owner should never take advantage of the short-term and underestimate the personal safety of others and others when purchasing products. Fifth: performance The performance of the color aluminum window is different due to the scope of use, but the following aspects are usually considered: strength, which is mainly reflected in the selection of the color aluminum window profile, whether he can withstand ultra-high pressure; airtight It is mainly reflected in the structure of doors and windows, whether the structure of the inner fan and the outer frame of the doors and windows is tight, whether the frameless balcony windows are tight and airtight; watertightness, mainly to check whether there are water accumulation and leakage in color aluminum windows; sound insulation, which Mainly depends on the sound insulation effect of insulating glass and other special sound insulation airtight strip structure, as well as the durability of other door and window accessories such as opening and closing force, heat insulation, nylon guide wheel durability, opening and closing lock durability.

The definition of swollen anesthesia is to infiltrate into subcutaneous adipose tissue by ultra-low concentration, high-dose, a large-volume local anesthetic (currently used lidocaine) as an anesthetic method for liposuction.
Swelling anesthesia was first proposed by Klein in 1987. It is also called [over-perfusion anesthesia". A large amount of solution containing adrenal and lidocaine is stably perfused into the skin through a peristaltic pump, causing edema and cell tissue gap in the subcutaneous tissue and its structure. The small blood vessels are separated and pressed to be locked, thereby achieving the effects of local anesthesia, pain relief, hemostasis, and tissue separation.
Swollen anesthesia can be used as separate local anesthesia or combined with general anesthesia or regional anesthesia.
The advantage of peristaltic pump in swelling anesthesia:
1, easy operated, non-contamination
2, foot pedal control ,safety & reliability
3, adjustable speed and left/right direction optional
