Detailed description of the invention
The invention provides the device of assisted respiartion aerosol gas and regulate the method for respiratory gas fog body, for making object of the present invention, technical scheme and effect clearly, clearly, referring to accompanying drawing examples, the present invention is described in more detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The design concept of technical solution of the present invention is as follows: owing to only entering the aerosol medication of bronchioles and alveolar and being deposited on competence exertion effect in small airway and alveolar, so need to guarantee that aerosol medication can enter respiratory tract with air-breathing, but also the duration that needs ensure respiration, extend the time of single breath, make breather (people) deeply breathe as far as possible.Like this, the speed of air-breathing and expiration need only be controlled.As minimalist program of the present invention, only three mouths need be set, make air inlet connector and the less speed that can control air-breathing and expiration of exhalation vents, extend the time of single breath.
According to above-mentioned design, the invention provides the device of the simplest assisted respiartion aerosol gas, specifically as shown in Figure 1, the structure drawing of device of assisted respiartion aerosol gas of the present invention, comprise: pipeline 400, and be arranged on pipeline 400 for connect aerosol injection apparatus 500 air inlet connector 100, for discharging the exhalation vents 200 of respiratory tract gas and exchanging mouth 300 for contacting the contact exchanged with respiratory tract.It should be noted that, exhalation vents not only air inlet can also discharge gas, air inlet connector is used for entering (also can be used for entering of air) of aerosol gas, when exhalation vents is less, the gas of breathing out can not be discharged timely, the gas of coefficient can not obtain timely, so just extends the duration of single breath, extends the fog medicine time of staying in vivo.Simultaneously, during expiration, pipeline produces end expiratory positive pressure, the alveolar gas being conducive to existing intrinsic positive end expiratory pressure is fully exhaled, at the end of expiration, pipeline pressure declines, air-breathing produces pipe negative pressure thereupon, by manually pressing aerosol injection apparatus, aerosol gas is made to enter pipeline, aerosol gas enters pulmonary along inspiratory airflow, when exhalation vents size is suitable, suitable and the inspiratory duration long enough of inspiratory flow rate can be ensured, so just the aerosol gas entering pipeline can be sucked pulmonary, ensure that aerosol gas (aerosol medication) is fully sucked pulmonary, play curative effect.
The device of the simplest assisted respiartion aerosol gas provided by the invention can not regulate expiratory resistance, the aerosol gas of injection and non-aerosol gas ratio and air-breathing speed can not be regulated, more can not the aerosol gas that aerosol injection apparatus sprays be observed, for this reason, present invention also offers a preferred version.Specifically as shown in Figure 2.
Refer to Fig. 2, the device of assisted respiartion aerosol gas of the present invention, comprising:
Pipeline 400 and be arranged on pipeline 400 for connect aerosol injection apparatus air inlet connector 100, for discharging the exhalation vents 200 of respiratory tract gas and the contact for contacting exchanging gas with respiratory tract exchanges mouth 300;
Be arranged on exhalation vents 200, for regulating the one-way breather valve 104 of expiratory resistance;
Be arranged on air inlet connector 100, for regulating the air-breathing current limiter 106 of aerosol gas and the non-aerosol gas ratio sprayed when air inlet connector connects aerosol injection apparatus.
Described one-way breather valve 104 allows gas to flow out from inside to outside, does not allow gas ecto-entad to flow into; When regulating expiratory resistance by one-way breather valve 104, expiratory resistance can be set according to the practical situation of breather (people), make the device of assisted respiartion aerosol gas be applicable to different breathers, and best expiratory resistance can be set.
Air-breathing current limiter 106 sets up on the basis of air inlet connector air inlet, mainly when air inlet connector connects aerosol injection apparatus, and the ratio of the aerosol gas flow regulating air inlet connector air inflow and aerosol injection apparatus to spray.Because the situation of breather is not quite similar, set up air-breathing current limiter 106, the device of assisted respiartion aerosol gas can be made to be applicable to different breathers and same breather different treatment phase, and air-breathing current limiter is air inflow size adjustment aforementioned proportion by regulating air.Described air-breathing current limiter 106 is one-way intake current limiter, only allows gas to enter, does not allow gas to flow out.
Please continue see Fig. 2, the device of assisted respiartion aerosol gas of the present invention, preferably, described pipeline 400 is transparent pipeline.Transparent pipeline conveniently can observe the situation that aerosol gas is inhaled into, and then effectively regulates the device of assisted respiartion aerosol gas.
