Intelligent micro-grid nebulization device and nebulization system

Abstract

The invention provides an intelligent micro-grid nebulization device and a nebulization system. The intelligent micro-grid nebulization device includes a medicine liquid cup, a nebulization plate, a mist spray nozzle, a breathing monitoring module, a T-shaped three-way joint or / and a mist storage tank and a controller, and a controller socket is arranged at the bottom of the medicine liquid cup. The intelligent micro-grid nebulization device is characterized in that the mist spray nozzle is connected with the mist storage tank or the T-shaped three-way joint to form an air flow channel for communicating with the respiratory tract of a patient, an air channel connecting opening is formed in the outer wall of the mist spray nozzle and communicates with the cavity of the mist spray nozzle, and the air channel connecting opening adopts a standard Luer connecting opening. A plug at one end of one nebulization control line is connected with the controller socket in an inserted mode, and theother end of the nebulization control line is connected to the controller. The breathing monitoring module arranged on the nebulization control line is connected to the controller, and the controllerreceives output signals of the breathing monitoring module and adjusts the working state and the mist output intensity of the nebulization plate according to the received output signals. The nebulization system is an intelligent micro-grid nebulization system with high efficiency, Internet of Things, easy to use and adaption to various application scenarios.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to the innovation and improvement of a micro-net atomizer and an atomization system, in particular to an intelligent micro-net atomizer and an atomization system. Background technique [0002] Nebulization inhalation treatment is to disperse the medicinal liquid into micron-sized fine mist liquid particles through the nebulizer, and reach the patient's lungs through the patient's respiratory tract, so as to achieve painless and rapid treatment such as cough, asthma, sore throat, pharyngitis and bronchial pneumonia The purpose of other diseases. The main equipment for atomization inhalation therapy is a micro-mesh nebulizer, which is composed of a liquid medicine cup, an atomizing tablet, a spray nozzle and a controller, and its core component is an atomizing tablet. The atomizing sheet is composed of piezoelectric ceramics and microporous mesh. The piezoelectric ceramics are ...

Problems solved by technology

The micro-mesh nebulizer is used in conjunction with the ventilator. It is mainly placed at the intake end of the ventilator humidification tank pipeline or the patient's inspiratory pipeline at the Y-shaped joint of the ventilator pipeline, that is, the end of the ventilator outlet pipeline. Because the ventilator tube There is still a distance between the location of the nebulizer on the road and the patient's respiratory tract. This distance is connected to the patient's respiratory tract through the ventilator pipeline. The drug particles atomized by the micro-mesh nebulizer will be on the inner wall of this ventilator pipeline. A part remains on the upper part, forming a liquid, which reduces the delivery amount of the drug, and the existing micro-mesh nebulizers are connected to the ventilator pipeline and the nebulization is turned on, and the mist is continuously released, regardless of the patient's inhalation and exhalation, micro-mesh The mesh nebulizers are all working to spray. At this time, part of the aerosol generated by the micro-mesh nebulizer will enter the respiratory tract with the patient's inhalation, and the other part will be wasted in the ventilator pipeline with the patient's exhalation. Therefore, now With micro-mesh nebulizer and ventilator application, the delivery volume is very low, and the drug waste is serious

[0004] When the micro-mesh nebulizer is used with a ventilator, it is mainly connected to the ventilator pipeline through a T-shaped tee joint. The T-shaped tee joint equipped by the existing micro-mesh nebulizer manufacturers is a right-angle connection. The sprayed aerosol directly hits the T-shaped three-way joint and the pipe wall of the ventilator connection channel, which increases the contact probability between the aerosol and the inner wall of the T-shaped three-way joint pipe, so that a part of the aerosol hits the inner wall of the pipe to form droplets Unable to deliver to the patient's respiratory tract resulting in some loss of drug that reduces delivery

[0005] Most patients with lung disease or respiratory disease have abnormal respiratory symptoms such as shortness of breath and shortness of breath. The existing nebulizers have no targeted solutions for such patients, and the atomized drug delivery depends entirely on the patient's spontaneous breathing , unable to guide patients to standard breathing, no guidance on nebulized drug administration, and lack of behavioral promotion for patients' respiratory rehabilitation
