Description of drawings
Fig. 1 is that gas of the present utility model, circuit are formed and theory diagram.
Fig. 2 is a circuit part composition frame chart of the present utility model.
The specific embodiment
This utility model can adopt the technical scheme shown in accompanying drawing:
The schematic diagram of gas circuit of oxygen inhalation instrument as shown in Figure 1, this figure left-half is the air path part of main frame with the part that pipeline connects, bottom right half part is the electronic control part of main frame.The circuit part schematic block diagram as shown in Figure 2.
After compressed oxygen enters the main frame air inlet,, pressure is carried out voltage stabilizing through air relief valve.Oxygen is by relief valve then, and relief valve is to be used for limiting maximum pressure in the oxygen uptake gas circuit, when in the gas circuit because certain special reason (as gas circuit obstructions, decompressor inefficacy etc.) is when causing pressure to surpass the air-channel system safe pressure, relief valve is open disappointing.Oxygen carries out the throttling restriction through manual flow velocity/permissible velocity valve then, regulates the back through the intelligence of proportional solenoid again and enters into effusion meter with certain flow velocity, and it can monitor the oxygen uptake flow velocity at any time.Enter wetting bottle (adding an amount of distilled water in the wetting bottle) then, enter in the patient body by Oxygen tube again after humidifying.
The gas that more than underdrawed enters the course of conveying of patient pulmonary.The Electronic Control plate (microcomputer control unit) of band micro computer provides the driving signal of monitoring, supervisory keyboard and the display process to blood oxygen saturation, pulse frequency, blood pressure, flow velocity, the processing of various alarm signal and proportional solenoid.The Electronic Control plate is also monitored complete machine power supply situation, the warning of sounding when outage.
In the air path part of Fig. 1, in the gas circuit case 7 of this instrument, mainly comprise air inlet 2 (source of the gas compressed oxygen input interface), air relief valve 3, relief valve 4, manual safety flow rate regulating valve 5, proportional solenoid 6, effusion meter 8, wetting bottle 9 and oxygen uptake mouth 10 etc.Described air inlet 2 is connected with source of the gas 1.The circuit structure of the circuit box 11 of circuit part is seen Fig. 2, and circuit part mainly comprises blood oxygen/pulse frequency probe and blood pressure probe (cuff formula) and display, the operation keyboard etc. of band micro computer electronics panel, power panel, patient end.
Air path part: air inlet, the interface of connection source of the gas and machine; Air relief valve carries out a pressure limiting voltage stabilizing with the source of the gas of various different pressures; Relief valve is to be used for limiting maximum pressure in the oxygen uptake gas circuit, when in the gas circuit because certain special reason (as gas circuit obstructions, decompressor inefficacy etc.) is when causing pressure to surpass the air-channel system safe pressure, relief valve is open disappointing, plays safe pressure limiting; Proportional solenoid is to be subjected to the curtage difference and the different flow speed control valve body of flow velocity, is executive component relatively more crucial in this utility model; Effusion meter is mainly monitored oxygen gas flow rate, and float-type flowmeter directly shows flow velocity; Electronic flowmeter is handled the back by electronic circuit A/D and show the flow velocity size on display along with the current/voltage signal magnitude of the different outputs of flow velocity does not wait.Can also carry out oxygen consumption according to this electronic signal calculates.But, this electronic signal because the output of the flow of proportional solenoid is not controlled by electronic control unit, micro computer is a size of knowing flow velocity, by with the product accumulation of time, also can calculate oxygen consumption.That is to say there is not electronic flowmeter, still can calculate oxygen consumption.Wetting bottle needs to add an amount of distilled water in the bottle so that humidify, like this patient to suck intravital oxygen be moistening, can reduce the stimulation that oxygen brings patient pulmonary; Oxygen tube, connection machine and patient's pipeline.The effusion meter that described effusion meter can use electronics to show, the suspended body flowmeter that also can use no electronics to show use the latter not only can not having monitoring oxygen uptake flow velocity under the electric situation, and cost is cheaper.
The control method of proportional solenoid is that the doctor is provided with patient's blood oxygen saturation upper and lower bound.Be set to 96 as the upper limit, lower limit is set to 88.Carry out intelligent oxygen uptake, also need the doctor preset flow rate to be set such as being at first oxygen supply under preset flow rate 6L/Min of 6L/Min. machine, through after a while, detect blood oxygen saturation and surpass 96, proportional solenoid is then turned down one-level automatically, if be 5L/Min, passes through certain hour (according to the clinical experience gained) again, find also to be higher than 96, proportional solenoid is then turned down one-level automatically again.。。Up to being 0, still be higher than 96, prompting blood oxygen saturation upper limit alarm, patient may not need oxygen uptake again or need the doctor to intervene.Otherwise if oxygen supply a period of time still is lower than 88 under the preset flow rate 6L/Min being lower than, proportional solenoid is then heightened one-level automatically.。。Up to being 6L/Min.If oxygen supply a period of time under preset flow rate 6L/Min, still be lower than 88, then point out the blood oxygen saturation lower limit to report to the police, need the doctor to handle: may need to heighten preset flow rate or go up respirator etc.Usually, the parameter that the doctor is provided with is more reasonable to this patient, always in reasonably dynamic adjustments variation between flow velocity and the blood oxygen saturation.
Other control mode may not only be provided with the foundation that bound is judged adjusting, and the judgment basis that two other bound is used as reporting to the police also is set simultaneously.Control method is many, and final realization " timely adjustment is carried out in the variation according to physical signs of patient " gets final product.
Circuit part: micro computer electronics panel, it is automatically controlled core component, the driving signal of proportional solenoid is provided, and monitoring, supervisory keyboard and the display process of blood oxygen saturation, pulse frequency, blood pressure, flow velocity, the processing of various alarm signal, oxygen consumption are calculated and calendar scheduling; Power panel is for equipment provides electric power resource.It can be adapter and so on; Blood oxygen/pulse frequency probe, sensor probe, in order to blood oxygen/pulse frequency of sampling patient, this sensor probe need act on patient all along, and the signal data of collection is the information source foundation of carrying out Based Intelligent Control; The blood pressure probe, sensor probe is in order to sampling patient's blood pressure signal; Display shows monitoring, is provided with, reports to the police and the various information of work calendar scheduling.Can be charactron or liquid crystal etc.; Guidance panel is to operator operation with the parts of parameter are set.
(after compressed oxygen, general 200kPa～600kPa) entered the main frame air inlet, through air relief valve, at 200kPa, air relief valve played pressure stabilization function to source of the gas here with pressure limit, is convenient to subsequent control.Oxygen is by relief valve then, and relief valve is to be used for limiting maximum pressure in the oxygen uptake gas circuit, when in the gas circuit because certain special reason (as gas circuit obstructions, decompressor inefficacy etc.) is when causing pressure to surpass the air-channel system safe pressure, relief valve is open disappointing.Then, oxygen carries out the throttling restriction through manual flow velocity/permissible velocity valve, regulates the back through the intelligence of proportional solenoid again and enters into effusion meter with certain flow velocity, and effusion meter can timely monitor oxygen uptake flow velocity.Enter wetting bottle then, add an amount of distilled water in the wetting bottle, also can increase medicine to improve therapeutic effect to distilled water.Oxygen after humidifying enters in the patient body by Oxygen tube, nose cup or face shield or intubate again.
Wherein manually flow velocity/permissible velocity valve can play two effects:
1. manual adjustments: because proportional solenoid is a normally open valve, under the situation of not having electricity, electromagnetic valve does not play throttling action, and the user can realize the oxygen uptake flow rate regulation by this valve of manual adjustments fully.At this moment be equal to common on the market oxygen inhaler (by manual adjustments oxygen uptake flow velocity) fully.This kind situation is no electric oxygen uptake;
2. security limitations: work if having under the situation of electricity, can at any time a fixed permissible velocity be set by this valve.Because some especial patient should not use too high flow velocity oxygen uptake, perhaps patient feels under the weather under too high flow velocity.Had after this security limitations, though oxygen inhalation instrument outage or oxygen inhalation instrument break down lost efficacy in the oxygen gas flow rate of oxygen inhalation instrument also be controlled in the margin of safety.Therefore, permissible velocity only breaks down at oxygen inhalation instrument outage or oxygen inhalation instrument and works when losing efficacy.
Wherein the intelligent conditioning signal of proportional solenoid derives from the micro computer on the Electronic Control plate.It is responsible for handling the situation of blood oxygen saturation that blood oxygen saturation situation, pulse frequency situation and doctor that the blood oxygen probe collection comes be provided with, pulse frequency bound alarming value and sends instruction to proportional solenoid.As previously mentioned, because some especial patient should not use too high flow velocity oxygen uptake, perhaps patient feels under the weather under too high flow velocity.Before giving the formal ventilation of patient, the doctor can be provided with a preset flow rate by menu, and this flow velocity is the Peak Flow Rate that patient may use.Like this, proportional solenoid just can only carry out the intelligence adjusting between 0～preset flow rate value.The situation that this kind has electromagnetic valve to participate in speed governing is intelligent oxygen uptake.
Flow velocity all is subjected to the monitoring of effusion meter in the whole process of this instrument.In Fig. 2, the Electronic Control plate of band micro computer provides the driving signal of monitoring, oxygen consumption calculating and timing, supervisory keyboard and the display process to blood oxygen saturation, pulse frequency, blood pressure, flow velocity, the processing of various alarm signal and proportional solenoid.
The Electronic Control plate is also monitored complete machine power supply situation, the warning of sounding when outage.
By above principle, same machine can be realized following 3 kinds of mode states at least:
A) intelligent oxygen uptake pattern: by microcomputerized control, change according to the patient's blood oxygen saturation that collects in good time, (between 0～preset flow rate value) changes the oxygen uptake flow velocity automatically in the flow rates that presets, thereby changes patient's concentration of oxygen inhalation.It has the characteristics of " in good time regulating automatically as required ".Under this pattern, oxygen inhalation instrument provides monitoring and warning function.This pattern is a marrow of the present utility model, is fit to most patients.
B) electric hand dynamic model formula is arranged: oxygen inhalation instrument is directly regulated manual/Safety knob for electric appliance and is carried out oxygen uptake under the situation of energising.Under this pattern, oxygen inhalation instrument provides monitoring and warning function, and intelligent oxygen uptake is not provided.This pattern is fit to needs to be provided and stablize the oxygen uptake flow velocity but the while needs alert detecting again in case the generation of oxygen therapy untoward reaction such as oxygen intoxication.
C) no electric hand dynamic model formula: under the cold situation of oxygen inhalation instrument, directly regulate manual/Safety knob for electric appliance and carry out oxygen uptake.Under this pattern, oxygen inhalation instrument can not provide monitoring and warning function, and intelligent oxygen uptake is not provided yet.This state is equal to present common oxygen inhaler on the market.This pattern can be used as extreme condition, as a kind of safe spare pattern of power shortage state.
