The utility model has the advantages of measuring transient flow and cumulative flow and displaying price.
Description
The utility model relates to a kind of device of measuring the patients accepting oxygen inhalation amount and representing its price of being used to, and is a kind of oxygen flow valuation device specifically.
Urgent patient in the hospital often needs oxygen uptake.Existing oxygen inhalation apparatus can only be checked instantaneous delivery, the oxygen that is sucked can not be carried out cummulative metering, can only charge according to oxygen time length.This charging method is not only very inaccurate, and error is big, unreasonable charges, and, the lost labor.
The utility model purpose is to overcome the shortcoming in the above-mentioned technology, proposes a kind of oxygen flow valuation device, makes it can not only measure instantaneous delivery, and can measure integrated flux and the price of expressing oxygen intake, and oxygen uptake is chargeed accurately, rapidly, and saves manually.
The utility model purpose is realized by following technical scheme: this oxygen flow valuation device, in the front of shell intelligence computation wiring board and LCDs are housed, enclosure is equipped with battery case, the zero clearing key switch also is housed on the shell, conversion the Show Button and rapid-acting coupling air intake opening, by connecting the flow control valve that flexible pipe is connected the rapid-acting coupling air intake opening and is contained in the humidification bottle import, the underwater of the cleaning that the flow regulation valve outlet port is stretched in the humidification bottle to be adorned by pipe, there is the gas outlet humidification bottle upper end, it is characterized in that also being equipped with in the enclosure flow transmitter, flow transmitter air intake opening and flow transmitter gas outlet are connected and are connected in the middle of the flexible pipe, sensor is vertical with flow transmitter to be installed, and the extension line of sensor is connected with connector socket on the intelligent integrating wiring board.
Flow transmitter comprises a transmitter housing, a flow converter air intake opening and a flow transmitter gas outlet are arranged on the transmitter housing, a magnetic conductivity impeller is housed in the transmitter housing, by bearing supporting impeller shaft, the impeller train wheel bridge is housed above the magnetic conductivity impeller, is pressed with sealing rubber ring below the transmitter loam cake.Make the oxygen in the flow transmitter housing can not be leaked to the outside.The flow transmitter air intake opening is less than the flow transmitter gas outlet.Oxygen enters from the rapid-acting coupling air intake opening, through connecting flexible pipe, enter in the flow transmitter housing by the flow transmitter air intake opening, speed is very big, be oriented in a tangential direction and impact the blade of magnetic conductivity impeller, make the magnetic conductivity impeller have rotating torque, overcome friction square and fluid resistance moment, the rotation of magnetic conductivity impeller, stabilization of speed after equalising torque.Adopt jewel bearing, friction force is very little.Under certain condition, the magnetic conductivity wheel speed is directly proportional with oxygen gas flow rate.Sensor comprises a sensor outer housing, and coil is housed in the sensor outer housing, is placed with the sensor iron core in the coil.Sensor is vertical with flow transmitter, is installed on the flow transmitter to cover, and forms magnetic field around the sensor.Because magnetic conductivity impeller and blade have magnetic conductivity, are in again in the magnetic field of sensor.The magnetic conductivity impeller of rotation, continuous cutting magnetic line, periodically changing the magnetic flux of sensor, thereby make sensor sensing go out electric impulse signal, this signal is drawn by the sensor extension line, after the amplification shaping of amplifier on the intelligent integrating wiring board, form continuous square wave with certain amplitude.Pass through the mcu programming computing on the intelligent integrating wiring board again, and error is revised at random in addition, goes out instantaneous delivery by liquid crystal display displays, integrated flux or price.Intelligence integrating wiring board is selected 21441 types intelligence integrating wiring board for use, is made by the East Sea, Wenzhou City instrucment and meter plant.Oxygen, enters in the humidification bottle behind humidification machine flow regulation valve regulation flow by transmitter gas outlet, connection flexible pipe, through humidifying, flows out from the humidification machine gas outlet, and the patients oxygen uptake is used.
The utility model advantage is rational in infrastructure, and is simple, not only can show instantaneous delivery, single-chip microcomputer integrating system by on the intelligent integrating wiring board can obtain integrated flow, can carry out the unit price setting by the single-chip microcomputer input system, can also directly demonstrate price, directly charge.Easy to operate, rapidly, save artificial because selected single-chip microcomputer is little power consumption low pressure prompting, outage data storage, realized easy to use, safety.
