Describe this utility model in detail below in conjunction with accompanying drawing:
As shown in Figure 1, it is to be formed by connecting in turn by pipeline 6 by flow tabular form oxygen mixing device 1, constant temperature humidifier 2, air gauge 3 and air storage bag 7, interface 4 and continuous positive pressure control valve 5.Oxygen mixing device is connected by pipeline with the constant temperature humidifier can constitute a main frame, is arranged in the housing, or is two separation members, is arranged on separately in the housing.Air gauge and air storage bag, continuous positive pressure control valve respectively are a separation member.
The composition of flow tabular form oxygen mixing device is as shown in Figure 2: the air inlet 8,10 of oxygen flow meter 9 and mass air flow sensor 11 is connected with high pressure oxygen source and air source respectively, and its gas outlet links to each other with the two-port of mixed oxygen pipe 12 respectively.
Flow tabular form oxygen mixing device can also be made structure as shown in Figure 3, take into account the mass air flow sensor skin at oxygen flow and be respectively equipped with two sleeve pipes, end in each sleeve pipe is provided with spring and is connected with effusion meter top elasticity, and oxygen and the air of taking into account mass air flow sensor through oxygen flow enter into mixed oxygen pipe by sleeve pipe again.
As shown in Figure 4, the constant temperature humidifier is made of humidification bottle 14 and thermostat 15.On the lid of humidification bottle, offer two holes and be used for connecting pipe, inlet gas 16, gas outlet 17, thermostat can be made cartridge type, and humidification bottle is seated in heating, and thermostat can be taked the electrical heating form, and is not with temperature display and is with two kinds of temperature displays.The person is provided with patient interface air flue temperature probe (critesistor) at the band temperature display, by showing options button, the actual temperature (constant temperature) of display setting temperature and patient interface air-flow.Not the temperature control humidifier panel with temperature display be provided with the temperature control tuning knob, the display lamp of heating, electromotion pilot lamp, power line.Burner on light, electromotion pilot lamp, temperature display, demonstration options button, temperature probe and temperature control accent are set on the panel of the temperature control humidifier of band temperature display to be turned round.
As shown in Figure 5, air gauge 3 and air storage bag 7 links to each other on the opposite each other by cross four-way pipe, and by pipeline with humidification bottle gas outlet 17 and have a stuffy nose that (face shield or tracheal intubation) interface 4 links to each other, the end of pipeline is provided with continuous positive pressure control valve 5.This control valve 5 can be bevel-type and also can be spring lobe formula.Hold the internal orifice (pressure modulating opening) of air inlet under the bevel-type control valve barrel level with both hands and offer bleeder port.The adjust blood pressure cap is connected with valve cylinder upper end screw.One adjust blood pressure awl post is arranged between valve cylinder internal pressure-regulating lid and pressure modulating opening, is spring on every side, upward supports the vertical spring base of awl post, supports down at the bottom of the pressure modulating opening valve cylinder on every side.Because the elastic force effect of spring is risen the awl post, its footstock is tight against adjust blood pressure cap inner roof wall, and conehead leaves pressure modulating opening.The gas that enters freely flows out by pressure modulating opening (being the internal orifice of air inlet) and valve cylinder leakage port from air inlet.Rotate pressure regulating cover, this lid and adjust blood pressure awl post is moved up and down along valve cylinder,, air-flow is applied different resistances by the pore size between cone governor stigma and the pressure modulating opening, gas is used and is set up and keep required continuous positive pressure through the escaped quantity of this space and leakage port in the control pipeline.As shown in Figure 6, spring lobe formula control valve is by valve cylinder, air inlet, flap, the flap axostylus axostyle, formation is turned round in spring and adjust blood pressure, wherein, the valve cylinder inwall has spiral lamination, bleeder port is offered in the barrel lower end, rotate the accent handle that adjust blood pressure is turned round, this top cover of turning round (spiral lamination is arranged on every side) is moved forward and backward in valve cylinder, spring and flap are applied different pressure to be used and sets up and keep required continuous positive pressure, when gas pressure in the pipeline surpasses the set pressure value, gas is promptly overflowed through flap and bleeder port, and can avoid because adult's lung tidal volume is bigger, thereby the fluctuation that expiratory pressure is increased in short-term at the expiration initial stage.
Work process of the present utility model is as follows:
1. set up and suck the gas oxygen concentration: the air inlet that (1) takes into account mass air flow sensor with oxygen flow is connected with high pressure oxygen source and air source (or air compressor) respectively.Closing each accent turns round.(2) determine the desired gas total flow.(3) determine required suction gas oxygen concentration.(4) determine requisite oxygen throughput and air mass flow: from " the different gas oxygen concentration (FiO that suck
2) time oxygen and air the flow-rate ratio table " check in and set up required FiO
2The time oxygen and air flow-rate ratio, calculate the flow of oxygen and air when required total flow again, or on " oxygen and air mass flow computing method ", directly find.When replacing oxygen flowmeter, need use the correction value oxygen flow with mass air flow sensor.(5) open air source, the rotary air effusion meter is transferred and is turned round, and sets up the required air flow.(6) open source of oxygen, the same requisite oxygen throughput of setting up.
2. set up required humidifier temperature: (1) in humidification bottle adding distil water to graduation mark.(2) bottle is placed into preheating on the hot plate.(3) rotate thermostat and transfer and turn round, the suction gas at patient interface place is reached and keep temperature required.
3. set up required continuous positive pressure: the interface that (1) will connect the threeway of nasal obstruction (face shield, tracheal intubation) stops up or the connection lung model.(2) slowly rotate the continuous positive pressure control valve, watch the atmospheric pressure value of air gauge indication simultaneously, set up and maintain continuous positive pressure required under the certain flow.If during the change flow, need adjust blood pressure again.
Arrive this, the setting process is all finished.To have a stuffy nose (face shield, tracheal intubation) be connected with the interface of threeway and fixing, can carry out continuous positive pressure breathing.
