Abstract
The anti-epidemic sustaining jet positive-pressure breather includes jet unit and breath air passage, and features the jet unit with oxygen inlet, air inlet and mixed air outlet, communicated with the oxygen passage and the mixed air outlet to output mixed air, oxygen passage and the mixed air passage connected separately to the driving pressure gage and mixed air passage pressure gage; and the mixed air outlet communicated with the breath mask via breath bellows. The present invention is suitable for breath support of patient suffering from respiratory disturbance, failure and especially SARS, and can make the patient suck positive pressure mixed air with oxygen and breathe out metabolic air.
Description
Technical field:
The invention belongs to medium is imported the intravital apparatus of people, be specifically related to a kind of apparatus that influences the patient respiration system with gas treating process.
Background technology:
At the beginning of 2003 in China mainland and Hong Kong, " atypical pneumonia " of Taiwan outburst, human life's health has been constituted great harm.This harm is except the not intellectual and its intensive infectiousness of SARS virus, life-support system, comprise the improper use of respiratory system, and owing to the respirator of equipment costs an arm and a leg, the quantity wretched insufficiency, cause numerous patients can only accept the nasal tube oxygen inhalation anti symptom treatment, lost valuable rescue chance.
The characteristics of incidence of SARS is to hit pulmonary function in early days, refractory hypoxemia and even ARDS (acute lung injury) occur, makes the patient die from respiratory failure.This is SARS patient's a major causes of death.According to relevant pathological study: patient's diseased region occurs that the pulmonary capillary non-inflammatory oozes out, interstitial edema, alveolar surfactant reduce, alveolar inner surface hyaline membrane forms, the blood gas barrier thickening, disturbance of gas diffusion, V/Q ratio imbalance, and then the diffusivity alveolar withers, pulmonary atelectasis, pulmonary consolidation.This is the total pathological processes of all ARDS.
Therefore, in the SARS treatment, implement effectively to breathe to support protection pulmonary function, the key treatment measure that become and improve cure rate, reduces case fatality rate.Therefore SARS patient mainly shows as the pulmonary ventilation obstacle under the hyperventilation, and breathing the main purpose of supporting is to set up Positive Airway Pressure, blows and opens and the supporting alveolar that withers, and reduces in the alveolar and oozes out, and corrects hypoxemia, the pathological process of blocking-up ARDS.At present the breathing Supporting Therapy to SARS patient mainly contain conventional oxygen uptake, the wound ventilation arranged, noinvasive ventilation three types of technology.
According to anti-SARS frontline medical staff's clinical experience, conventional oxygen uptake, there is wound ventilation unsatisfactory to the therapeutic effect of SARS.For this reason, noinvasive ventilation, continuous positive pressure venti lation, incomplete assisted ventilation technology become the key treatment means at SARS.Domestic clinical use at present mainly be the BiPAP S/T ventilator of import, this machine structure is numerous and diverse, complicated operation.Every price is up to tens thousand of units.And airway pressure gauge is not set, and inconvenience is carried out airway pressure and is monitored.Chinese patent CN88211527 " pneumatic type respirator ", CN94242236 " single air-supply palm type first-aid respirator ", CN90224512 disclosed technical schemes such as " miniature anesthesia respirators ", major part need be provided with pneumatic, electric element, and the mechanical response part is many.Corresponding, its functional reliability is restricted.Above-mentioned domestic and international respirator does not all have infection design, and the patient expired spittle is to the pollution of respirator, and to the pollution of ward environment, is to make large quantities of medical workers be poured on the important step of a line.
Summary of the invention:
The purpose of this invention is to provide a kind of simple in structure, reliable operation, the cost cost is low, and has the infection jet continuous positive airway pressure respiratory organ of infection function.
This utility model is taked following technical scheme.Infection jet continuous positive airway pressure respiratory organ, include mjector, breathe gas circuit, mjector is provided with oxygen intake, air intake, mixed gas outlet, the reducing place of the oxygen channel that is communicated with through oxygen intake is communicated with air intake, its knot mouthful connection mixed gas outlet output gaseous mixture, oxygen channel and mixed gas passage sensing induction respectively connect driving pressure harmony in the exterior airway pressure gauge; The mixed gas outlet that mjector is provided with is communicated with inhalation device.
Mjector is the integral module structure, and oxygen, air and mixed airflow passage are communicated with by the process channel in the module.Non-detachable mold block structured material can adopt whole light metal, and for example integral Al-alloy module or high pressure resistant engineering plastics module or disposable engineering plastics module are provided with the gas channel formation.Mixed gas outlet is communicated with the output threeway, and output threeway one end is communicated with inhalation device through breathing corrugated tube 1, and an end is communicated with air storage bag.
Breathe gas circuit and be communicated with the threeway of Y shape, Y shape threeway one end is communicated with the mixed gas outlet that mjector is provided with through breathing corrugated tube, and an end is communicated with breathes corrugated tube and dissipation jar.
The present invention has significant technique effect compared to existing technology.Adopt the jet entrainment effect, utilize source of oxygen pressure, suction also mixes ambient air stream, is equipped with air storage bag and regulates the pressure balance that the patient exhales and inhales, and whole hard structure can make things convenient for the sterilization of respirator integral high pressure, guarantees the instrument sterile use.As adopting the disposal molding engineering plastics, its cost will be very cheap, be convenient to be extensive use of, and guarantee that the patient obtains in time suiting the medicine to the illness rescue.The pathogenic microorganism that the patient breathes out carries out innoxious discharging through dissipation jar disinfection, protects the cleaning ambient in ward to greatest extent.Simultaneously, according to the patients ' interest principle of optimality, accept effective treatment and should be considered as the due rights and interests of patient.This utility model provides probability for realizing this principle.Product model machine practical probation, the BiPAP S/T ventilator of effect and import is identical, but its cost is cheap greatly.Through experts' evaluation: " reaching advanced world standards ".
