Another data acquisition input port of this single-chip microcomputer is connected to a gauge tap;

Clock output/the input end of this single-chip microcomputer is connected to a clock circuit.

Wherein this gauge tap is contained on the knob of inhalator of oxygen supply device.

Description of drawings

For further specifying structure of the present utility model and feature, below in conjunction with drawings and Examples the utility model is done a detailed description, wherein:

Fig. 1 is circuit theory diagrams of the present utility model;

Fig. 2 is the structure principle chart that the utility model is used in oxygen inhalation apparatus.

Embodiment

See also Figure 1 and Figure 2, be circuit theory diagrams of the present utility model.A kind of oxygen therapy monitor of the utility model, comprising: a single-chip microcomputer IC1;

The output of this single-chip microcomputer IC1/input end RB3, RB4 is connected with the input end SDA of two memory IC 2, IC3;

Another output/input end RB0, RB1, the RB2 of this single-chip microcomputer IC1 are connected to display module LCD;

The data acquisition input port RA2 of this single-chip microcomputer IC1 is connected to a cipher key switch K2;

Another data acquisition input port RB5 of this single-chip microcomputer IC1 is connected to a gauge tap K1;

This gauge tap K1 is contained on the inhalator 20 of oxygen supply device, rotates synchronously with knob 21 on the inhalator 20.

The course of work of the present utility model is:

Please consult Fig. 1 and Fig. 2 again, the knob 21 on the inhalator 20 of turn oxygen supply device at first, be contained in because of gauge tap K1 on the inhalator 20 of oxygen supply device, again with inhalator 20 on knob 21 rotate synchronously, so when the knob 21 on the inhalator 20 of turn oxygen supply device, gauge tap K1 opens simultaneously; The signal wire that is connected on the gauge tap K1 links to each other with the data acquisition input port RB5 of single-chip microcomputer IC1 with R3 by resistance R 4.When patient does not carry out oxygen uptake, be contained on the inhalator 20 oxygen therapy monitor gauge tap K1 and be in " leading to " state, make the data acquisition input port RB5 of single-chip microcomputer IC1 be in high level, at this moment, the single-chip microcomputer IC1 in the oxygen therapy monitor does not carry out timing.When patient begins oxygen uptake, in the time of knob 21 on the turn inhalator 20, driven the oxygen therapy timing gauge tap K1 that is contained on the inhalator 20, make oxygen therapy timing gauge tap K1 be in the state of " breaking ", the data acquisition input port RB5 level of single-chip microcomputer IC1 is by high step-down, single-chip microcomputer IC1 receives this signal by high step-down, moves the respective service program of oxygen uptake timing at once.

Memory IC 2, IC3 are a kind of serial CMOS electrically alterable storages, and the significant data that is used for the storage system operational factor and need preserves in circuit guarantees that data are not lost under the situation of power down, and memory IC 2 is gone back the double as key and used.After patients accepting oxygen inhalation finishes, new patients ' demand oxygen uptake is arranged again, monitor will be done the zero clearing action this moment, so that restart timing.Monitor need compare with the data in the key when doing the zero clearing action, when the data in the key conform to system is set, can carry out zero clearing.

At ordinary times, memory IC 2, IC3 are by pulling into high level on resistance R 1, the R2, and single-chip microcomputer IC1 need just can control memory IC 2, IC3 and both can to memory IC 2, when IC3 carries out read-write operation.Four liquid crystal of low-power consumption (LCM045) display module LCD is adopted in the demonstration of native system, and when monitor picks up counting, single-chip microcomputer IC1 delivers to timing time on the LCD MODULE LCD.At ordinary times, cipher key switch K2 is in " breaking " state, when system needs zero clearing, makes cipher key switch K2 be in " leading to " state when inserting key (not shown in the figures, as to be prior art), and single-chip microcomputer detects this signal, cooperates key to carry out system's zero clearing.

When patient begins oxygen uptake, the knob 21 on the turn inhalator 20 makes the oxygen therapy timing gauge tap K1 that is contained in the top produce action, and single-chip microcomputer IC1 detects this action and enters the timing service routine immediately, and timing is presented on the display module LCD.Suspend oxygen uptake as need, close the knob 21 of inhalator 20, this moment, single-chip microcomputer IC1 was not-time and data are preserved automatically, continued oxygen uptake as need, the knob 21 on the turn inhalator 20, and the timing of single-chip microcomputer IC1 accumulative total, and the time be presented on the display module LCD during accumulative total.Oxygen uptake finishes, and cooperates key to carry out system's zero clearing by medical personnel, for next oxygen uptake is got ready.

This oxygen therapy monitor adopts international advanced PIC single-chip microcomputer, oxygen time is carried out science, timing exactly, and show oxygen time in real time, exactly by LCD MODULE LCD (LCD).After patients accepting oxygen inhalation was finished, hospital collected the charges according to the shown time of monitor.

The utlity model has following advantage:

1, can accurately know the record oxygen time.

2, the unnecessary dispute between the hospitalized patients has been reduced or remitted in science timing.

3, former oxygen supply device is not had big change, saved the transformation funds.

4, this instrument volume is little, and is in light weight, safe and reliable, elegant in appearance, is suitable for producing in batches.
