Switch socket 4: the connection atomizer controls the start and pause of the vibration atomizer.
The structure and function of the present invention are further described below:
with continued reference to fig. 1, a non-invasive ventilation mask for inhalation synchronized vibration and nebulization, comprising: the mask module is provided with an atomization hole 6 and a vent hole 7 communicated with a breathing pipeline 8 of the breathing machine; synchronous vibrations atomizing module, it includes: a vibration atomizer 3, the outlet of which is detachably connected with the atomization holes 6; the airflow direction sensing device 5 is arranged in the position, close to the vent hole 7, of the breathing pipeline 8 and can detect the direction of airflow passing through the position; and the controller 2 is used for switching on or switching off the vibration atomizer 3 according to the electric signal of the air flow direction monitored by the air flow direction sensing device 5, correspondingly, the vibration atomizer 3 is switched on when a patient inhales, and the vibration atomizer 3 is switched off when the patient exhales.
In this embodiment, the breathing circuit 8 also serves as an exhalation passage for the patient, an exhaust valve dedicated to exhalation is provided on the breathing circuit 8, and the air flow direction sensing device 5 is provided between the exhaust valve and the ventilation hole 7. It should be noted that, regarding the arrangement of the exhaust valve, the existing noninvasive ventilation mask belongs to the prior art, and such an exhaust valve is also arranged on the respiratory tube, so that it can also be seen that under the existing ventilator system, the ventilation hole is used as a channel for inspiration and expiration at the same time, and therefore, the gas in the pipeline from the ventilation hole 7 to the exhaust valve through the breathing pipeline exists in the forward direction and the reverse direction. It should be noted here that the pressure of the oxygen supplied from the ventilator through the breathing pipe 8 is low, and the position of the airflow direction sensing device 5 is close to the position of the ventilation hole 7, so that when the patient exhales, a reverse airflow direction is generated at the position of the airflow direction sensing device 5.
In this embodiment, the airflow direction sensing device 5 is a flow sensor.
In another embodiment, the airflow direction sensing device 5 is two pressure sensors located at different positions along the length direction of the breathing circuit 8, and the controller 2 is provided with a comparator for comparing the monitored values of the two pressure sensors, and determines the airflow direction by comparing the pressure values of the two pressure sensors. The figures do not show the specific positions of the two pressure sensors in detail.
In this embodiment, referring to fig. 1, the synchronized vibration and nebulization module is provided with a nebulization delivery switch that keeps the vibration nebulizer 3 continuously on, and an inhalation synchronized switch that can be turned on only when the patient inhales, as instructed by the controller 2.
In this embodiment, referring to fig. 1, a strap 1 is provided around the mask module.
In this embodiment, with continued reference to fig. 1, the atomizing aperture 6 is disposed directly above the vent aperture 7 such that atomized particles fall in the vicinity of the vent aperture 7 under the force of gravity.
When the patient does not need to be nebulized, only the breathing circuit 8 is connected for non-invasive ventilation. When a patient atomizes, the vibration atomizing module can be connected through the atomizing hole 6, and the airflow direction sensing device 5 is connected between the vent hole 7 and the breathing pipeline 8. The air flow direction sensing device 5 monitors the start and the end of inhalation air flow, and feeds back to the controller 2 to control the vibration atomizer 3, atomization starts along with the start of inhalation of a patient, atomization pauses along with the expiration of the patient, and an inhalation synchronization function is provided. The mask can ensure that the mask can vibrate and atomize simultaneously during the noninvasive ventilation, the noninvasive ventilation is not affected, and the atomization efficiency and the medicine utilization rate are greatly improved.
For the noninvasive ventilation patient, no special atomization hole is arranged on the mask when the noninvasive ventilation patient is atomized, so that the noninvasive ventilation is required to be disconnected or jet atomization is required to be added into a respiratory pipeline. If the noninvasive ventilation is disconnected, the patient is unsafe for some critical patients, if the respiratory pipeline is not disconnected and the jet atomization is added, the atomization efficiency is lower, and the use of the noninvasive ventilation can be influenced by the jet atomization airflow. The existing vibration atomizing device can not influence noninvasive ventilation and has the atomizing efficiency about twice higher than that of the common jet atomizing device, but the existing vibration atomizing device cannot be integrated into the noninvasive ventilation mask, and is continuously atomized and is not related to the inhalation and exhalation phases of a patient, and a lot of atomized particles are wasted when the patient exhales. By the scheme of the embodiment, the mask capable of integrating atomization is provided, and atomization is inhalation synchronous vibration atomization.
The integrated mask integrates nebulization without the need to disconnect non-invasive ventilation during non-invasive ventilation. The vibration atomizing module connected does not affect noninvasive ventilation and has about twice higher atomizing efficiency than the common jet atomizing device. In addition, the inhalation synchronization function is added to synchronize with the inhalation of a patient with noninvasive ventilation, so that the atomization treatment efficiency and the medicine utilization rate are improved.
In specific use, when the noninvasive ventilation patient does not need atomization, the noninvasive ventilation is carried out only by connecting the breathing pipeline 8. When a noninvasive ventilation patient atomizes, the vibration atomizing module can be connected through the atomizing hole 6, and a pressure sensor is connected between the ventilation hole 7 and the breathing pipeline 8. And (3) turning on an atomization conveying switch of the controller, and starting continuous vibration atomization. The inhalation synchronous switch is turned on to start the inhalation synchronous function, the pressure sensor monitors the start and the end of inhalation airflow, and the pressure sensor feeds back to the controller to control the vibration atomizer, the atomization starts along with the start of inhalation of a patient, and the atomization pauses along with the expiration of the patient.
The foregoing is a preferred embodiment of the present invention, and various changes and modifications may be made therein by those skilled in the art without departing from the general inventive concept, and such changes and modifications should be considered as falling within the scope of the claimed invention.
