Abstract

The invention discloses a non-invasive ventilator capable of reversely adjusting inhaling/ exhaling pressure ratio. The non-invasive ventilator comprises a mask, and a turbine motor which is communicated with the mask through an air pipeline; a solenoid valve is arranged on the air pipeline and used for regulating the output pressure and flowing velocity of the ventilator and lowering down the minimum IPAP or EPAP pressure to be zero. According to the non-invasive ventilator, the solenoid valve is arranged and can quickly switch inhaling pressure and exhaling pressure, thus the problem that the inhaling pressure cannot be less than the exhaling pressure can be solved, and an optimal optional scheme is provided for the early treatment of sleep apnea hpoventilation syndrome and chronic obstructive pulmonary disease.

Description

A kind of suction/exhale phase pressure than the noninvasive ventilator that can oppositely regulate

Technical field

The present invention relates to a kind of suction/exhale phase pressure than the noninvasive ventilator that can oppositely regulate.

Background technology

Clinically, two level respirator is widely used in the treatment of the mild or moderate interference with respiration diseases such as respiratory failure, pulmonary heart disease, chronic obstructive pulmonary disease, motoneuron, myasthenia.CPAP and continuous positive pressure venti lation (Continuous Positive AirwayPressure) are as one of its a kind of conventional mechanical ventilation mode, and its inspiratory phase pressure (IPAP) being in the nature two level respirator equals a kind of pattern time expiratory phase pressure (EPAP).Namely the malleation air-flow continued is sent into air flue with face shield by CPAP, imposes malleation in air flue to a certain degree artificially, thus be conducive to preventing airway collapse within the whole breathing cycle, increases functional residual capacity, improves lung compliance, and improve Oxygenation.General 4 ~ 12cm the water column of CPAP normal value, in particular cases can reach 15cm water column, be widely used in the treatment of sleep apnea syndrome at present.

The acting as of EPAP in the process using CPAP mode treatment sleep apnea: by giving malleation in end-tidal, add the functional residual capacity of lung, cause pharyngeal longitudinal traction, causing it more not easily to fall into impatency plug, giving the speed that when positive airway pressure has also delayed to exhale, intra-airway pressure declines simultaneously when exhaling.Theoretical place mat has been made in some diseases is carried out in these effects treatment with regard to can replace CPAP for EPAP.In addition, the effect of vital capacity in increase upper respiratory tract compliance about increasing has been done and has been described comparatively accurately in relevant document.

As above-mentioned, if EPAP will carry out the treatment of disease as a kind of independently remedy measures, in CPAP the pressure of inspiratory phase and IPAP effect not indispensable.IPAP is applicable to thorax limitation of activity that a variety of causes causes or the disease of lung expansion caused by obstacle, and for the normal patient of some inspiratory phases, IPAP can be considered nonessential.And interrelated data shows, when IPAP long-term too high time, the muscle disuse atrophy that air-breathing is relevant may be caused.So use CPAP treatment originally the normal disease of respiratory muscle time there is a kind of inevitably potential safety hazard undoubtedly.

Clinically, CPAP is used to treat in the process of sleep apnea syndrome at us, the value of CPAP will adjust according to the different conditions of different patients and same patient, when weight in patients increase, excessive drinking, flu or rhinitis are shown effect, the pressure removed needed for sleep apnea will improve accordingly, while adding EPAP numerical value, too increase IPAP, but the respiratory muscle of this Disease being normal mostly, just there is the risk causing normal respiratory muscle disuse atrophy in this.Therefore, a kind of noninvasive ventilator is needed can to regulate arbitrarily the pressure ratio of air-breathing and expiration, particularly for the sleep apnea patient needing pressure higher.In existing noninvasive ventilator, inspiratory phase pressure and expiratory phase pressure must meet IPAP and be more than or equal to EPAP; And most noninvasive ventilator changes pressure by regulating turbine speeds, thus also cannot accomplish the simple EPAP pattern that IPAP equals 0.

Summary of the invention

The present invention is in order to solve the problem, and propose a kind of suction/exhale phase pressure than the noninvasive ventilator that can oppositely regulate, the numerical value that this device meets IPAP can arbitrarily adjust as required, can be less than EPAP, even can meet IPAP=0.The respirator meeting this condition can be applied in the treatment of disease more widely.

To achieve these goals, the present invention adopts following technical scheme:

A kind of suction/exhale phase pressure than the noninvasive ventilator that can oppositely regulate, comprise face shield and turbine, turbine is communicated with face shield by breather line, and breather line is provided with electromagnetic valve, the pressure that electromagnetic valve adjustment respirator exports and flow velocity, and make minimum IPAP or EPAP Pressure Drop to 0.

Described face shield, be conventional products existing in prior art, be widely used in the treatment of the mild or moderate interference with respiration diseases such as respiratory failure, pulmonary heart disease, chronic obstructive pulmonary disease, motoneuron, myasthenia, the present invention, repeats no more without improvement its structure.

Operation principle of the present invention is:

During use, according to the state of an illness needs of patient, the patient of such as obstructive sleep apnea low-ventilatory syndrome, or chronic obstructive pulmonary disease needs the patient of lung rehabilitation, mainly need PEP (EPAP), we can arrange respirator pressure of inspiration(Pi) is zero or is less than the numerical value of EPAP, and after patient starts air-breathing, electromagnetic valve cuts out rapidly or turns down thus reaches required treatment pressure.

Beneficial effect of the present invention is:

By arranging electromagnetic valve, achieving pressure of inspiration(Pi) and breathing the quick switching of air pressure, solving pressure of inspiration(Pi) can not lower than a difficult problem for expiratory pressure, to sleep apnea ventilate syndrome and the early stage treatment of chronic obstructive pulmonary disease provide the suitableeest possibility.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Detailed description of the invention:

Below in conjunction with accompanying drawing and embodiment, the invention will be further described.

A kind of suction/exhale phase pressure than the noninvasive ventilator that can oppositely regulate, comprise face shield and turbine, turbine is communicated with face shield by breather line, and breather line is provided with electromagnetic valve, the pressure that electromagnetic valve adjustment respirator exports and flow velocity, and make minimum IPAP or EPAP Pressure Drop to 0.

Face shield, be conventional products existing in prior art, be widely used in the treatment of the mild or moderate interference with respiration diseases such as respiratory failure, pulmonary heart disease, chronic obstructive pulmonary disease, motoneuron, myasthenia, the present invention, repeats no more without improvement its structure.

During use, according to the state of an illness needs of patient, the patient of such as obstructive sleep apnea low-ventilatory syndrome, or chronic obstructive pulmonary disease needs the patient of lung rehabilitation, mainly need PEP (EPAP), we can arrange respirator pressure of inspiration(Pi) is zero or is less than the numerical value of EPAP, and after patient starts air-breathing, electromagnetic valve cuts out rapidly or turns down thus reaches required treatment pressure.

By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
