Description of the Invention: [Technical Field] The present invention relates to a pressure conversion system, in particular to a mercury-free liquid column sphygmomanometer using such a pressure conversion system as a non-mercury working fluid Instead of mercury, it provides the same pressure readings as traditional mercury-based sphygmomanometers. [Prior Art] Mercury is a mercury name, and a liquid substance in which a silver-white metallic luster is flashed in a thermometer is mercury. — An ordinary rod-type vitremeter contains about 1 gram of mercury, and a benchtop sphygmomanometer contains about 5 grams of mercury. At normal temperature, it can be evaporated to form mercury vapor. Human inhalation can cause damage to the nervous system, and severe mercury poisoning can even lead to death. The goal is to reduce the use of mercury-containing thermometers and sphygmomanometers. In Europe, countries such as Britain, France, Denmark, and the Netherlands have begun to restrict the use and production of mercury thermometers. Since 2000, the United States has started to ban mercury thermometers in several states and cities such as San Francisco, Boston, and Michigan. At the same time, the EU is stepping up the development and promotion of #代产品. At present, other blood pressure monitors include electronic blood pressure monitors and liquid-free blood pressure monitors. The former is prone to errors; the latter has metal fatigue problems. ΐ ΐ ΐ! The reason for the ban of the pressure gauge is the toxicity of mercury. At present, the specific gravity phase 4 is not found: non-toxic substances. However, many doctors are still accustomed to, prefer to use traditional blood pressure, five ==^^ her 丝 纠 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( Liquid replaces mercury,

The upper end of the glass tube is open to the atmosphere, and the top cover is With a metal cap, a cork pad, a suede pad and a metal mesh in the cap allow air to flow in and out. The lower end of the glass tube communicates with the mercury trough, and contains 60g of mercury. The adjustment switch is connected to mercury. When used, the switch is opened and the slot is opened. The internal mercury can enter the glass tube, and the switch is closed to prevent the mercury from overflowing. Mercury The specific gravity is as high as 13 6g/cm3, so the height of the mercury column of 3〇 cm is enough to reflect the general blood pressure range. If it is replaced by water, it is enough to be 408cm. As shown in Figure 1, the mercury-free liquid of the present invention is shown. The embodiment of the pressure conversion system of the column sphygmomanometer includes a pressure generating device, a pressure changer 2, and a liquid column pressure display 3.

The air pressure bag is connected to the pressure changer. (4) The working fluid density and the mercury density paper value are converted and decompressed so that the working fluid in the fluid storage tank 33 can generate a liquid column height equivalent to the conventional mercury column in the transparent tube 31. The second diagram, in accordance with the pressure exchanger 2 of the present invention, may include a "first plunger mechanism, a second plunger surface 245," a connecting tree 247, and a linkage member 248. The first plunger mechanism 240 includes a first outer casing 2401 and a first-plunger 2402. The first-outer 2401 is in communication with the secret bag 12. The first plunger can be slid in the outer casing 2401 by the gas in the air pocket η. The second plunger mechanism 245 includes a second outer casing 2451 and a second outer plug 2452. The second outer casing 2451 is in communication with the fluid reservoir 33 and is coupled to the first outer casing 24〇1 by means of a connecting member 247. The second plunger 2452 and the first plunger mechanism 240 are slid through the second housing 2451 through the interlocking member 248, and the liquid s 31 ' in the fluid reservoir 33 is generated to generate a liquid column change representative of blood pressure. .
