Summary of the invention
The purpose of this utility model is to provide a kind of electronic-controlled installation of anesthesia evaporator anesthetic gases output concentration; Can export many feedback signals such as concentration, flow, temperature and ambient pressure variations according to reality and make timely compensation adjustment; Thereby accurate output anesthesia mist satisfies and induces, keeps the narcose actual needs of patient.
The technical scheme of this utility model is following:
The electronic-controlled installation of anesthesia evaporator anesthetic gases output concentration; It is characterized in that: comprise outer yoke, inner yoke, Magnet, coil, valve seat, guide pillar, pull bar, return spring, spool; Wherein said inner yoke is positioned at outer yoke inner chamber middle part; Said Magnet is provided with along the outer yoke internal chamber wall, and said coil is between inner yoke and Magnet; Said valve seat one side is provided with air inlet, and the opposite side relative with air inlet is provided with the gas outlet, and the bottom is provided with carrier gas inlet, and top is connected with the bottom of said outer yoke; Said pull bar, return spring, spool are positioned at valve seat; Said outer yoke bottom is provided with two guide holes that are communicated with valve seat; Said guide pillar is movably arranged in the said guide hole; The guide pillar upper end connects said coil; The lower end connects said pull bar, and said pull bar connects the upper end of said spool through said return spring, and the lower end of said spool is arranged in the carrier gas inlet of valve cup bottom portion.
Technique scheme also can be replenished following technical characterictic in the practical implementation process:
The top of said outer yoke is provided with the magnetic conduction joint, and said magnetic conduction joint is with the top seal of said outer yoke.
Said Magnet is shaped as a watt shape, and magnetizing direction is a radial magnetizing, one to the N utmost point one to the S utmost point, some blocks of Magnet are along outer yoke internal chamber wall uniform distribution.
Be provided with sealing gasket between said spool and the valve seat; Said sealing gasket can adopt tower sealing gasket.
The coil of this utility model is connected with the CPU control unit.When coil passed through electric current, coil produced pulling force upwards in magnetic field, and pull bar pulling spool moves upward and opens carrier gas inlet, and part carrier gas air communication is mixed with bypass after crossing anesthetis volatilization chamber again, and output needs the anesthesia gaseous mixture of concentration.When air-flow, pressure, temperature fluctuation; The CPU control unit is reacted rapidly, through the electric current of adjustment through coil, and the amplitude that the adjustment spool moves upward; The size of control carrier gas inlet folding degree; Make through the load volume of carrier gas inlet adjusted, thereby output anesthesia mist accurately guarantees output steady concentration property.
Description of drawings
