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 the actual needs of inducing, keep the anesthesia of patient state.
The technical solution of the utility model is as follows:
A kind of anesthesia evaporator output concentration control apparatus, 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, described Magnet arranges along the outer yoke internal chamber wall, and described coil is between inner yoke and Magnet; Described 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 described outer yoke; Described pull bar, return spring, spool are positioned at valve seat; Described outer yoke bottom is provided with two guide holes that are communicated with valve seat, described guide pillar is movably arranged in the described guide hole, the guide pillar upper end connects described coil, the lower end connects described pull bar, described pull bar connects the upper end of described spool by described return spring, and the lower end of described spool is arranged in the carrier gas inlet of valve cup bottom section.
Technique scheme also can be replenished following technical characterictic in specific implementation process:
The top of described outer yoke is provided with the magnetic conduction joint, and described magnetic conduction joint is with the top seal of described outer yoke.
Described Magnet is shaped as a watt shape, and magnetizing direction is radial magnetizing, and one to the N utmost point one to the S utmost point, and some blocks of Magnet evenly distribute along the outer yoke internal chamber wall.
Be provided with sealing gasket between described spool and the valve seat; Described sealing gasket can adopt tower sealing gasket.
Coil of the present utility model is connected with the CPU control unit.When coil when the electric current, coil produces pulling force upwards in magnetic field, pull bar pulling spool moves upward and opens carrier gas inlet, part carrier gas air-flow mixes with bypass after by anesthetis volatilization chamber again, exports the anesthesia gaseous mixture that needs concentration.When air-flow, pressure, temperature fluctuation, the CPU control unit is reacted rapidly, by adjusting the electric current by coil, adjust the amplitude that spool moves upward, the size of control carrier gas inlet opening degree, make by the load volume of carrier gas inlet adjusted, thereby output anesthesia mist accurately guarantees the stability of output concentration.
Description of drawings
Fig. 1 is the schematic diagram of the concentration output-controlling device of anesthesia evaporator
Fig. 2 is the longitudinal profile structural representation of a kind of embodiment of the present utility model.
The specific embodiment
As shown in Figure 2, this utility model comprises outer yoke 1, inner yoke 2, Magnet 3, coil 4, valve seat 5, guide pillar 6, pull bar 7, return spring 8, spool 9, wherein said inner yoke 2 is positioned at outer yoke 1 inner chamber middle part, described Magnet 3 is along outer yoke 1 internal chamber wall setting, and described coil 4 is between inner yoke 2 and Magnet 3; Described valve seat 5 one sides are provided with air inlet 51, and the opposite side relative with air inlet is provided with gas outlet 52, and valve seat 5 bottoms are provided with carrier gas inlet 53, and valve seat 5 tops are connected with the bottom of described outer yoke 1; Described pull bar 7, return spring 8, spool 9 are positioned at valve seat 5; Described outer yoke 1 bottom is provided with two guide holes that are communicated with valve seat 5, described guide pillar 6 is movably arranged in the described guide hole, guide pillar 6 upper ends connect described coil 4, the lower end connects described pull bar 7, described pull bar 7 is by the upper end of the described spool 9 of described return spring 8 connections, and the lower end of described spool 9 is arranged in the carrier gas inlet 53 of valve seat 5 bottoms.
The setting of above-mentioned two guide holes, guide pillar plays position-limiting action, can guarantee that coil only moves up and down and can not rotate.
