Description

An intelligent micro-net atomizer and atomization system Technical field

The invention belongs to the technical field of medical devices, and relates to the innovation and improvement of a micro-mesh atomizer and an atomization system, in particular to an intelligent micro-mesh atomizer and an atomization system.

Background technique

Nebulized inhalation therapy is to disperse the medicinal solution into micron-sized fine mist liquid particles through the atomizer, 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 treatment is a micro-net atomizer, which is composed of a liquid cup, an atomizing sheet, a spray nozzle and a controller, and its core component is the atomizing sheet. The atomization sheet is composed of piezoelectric ceramics and microporous mesh sheets. The piezoelectric ceramics are used to generate mechanical energy under the excitation of electric signal sources to drive the micro mesh sheets to vibrate to achieve the purpose of fogging. This kind of atomization method does not affect Local air pressure, low power consumption, high fogging efficiency.

Nebulization therapy is often used in IUC wards, and it is often used in conjunction with a ventilator or anesthesia machine. Since the ventilator needs to monitor the patient's breathing state, the gas path formed by the breathing circuit and the patient's respiratory tract must be airtight, so cooperation is required The nebulizer used in the ventilator or anesthesia machine is not allowed to affect the air pressure in the ventilator pipe, otherwise it will easily cause the ventilator to misjudge or alarm. The micro-mesh nebulizer uses the micro-mesh vibration of the micro-mesh atomizing sheet to squeeze the liquid out of the micro-mesh to form an aerosol, which does not affect the local air pressure, so it is the most suitable atomization in the application scenarios of ventilator or anesthesia machine Device. The micro-mesh nebulizer is used in conjunction with the ventilator. It is mainly placed at the inlet end of the ventilator humidification tank pipeline or the patient inhalation line of the ventilator pipeline Y-connector, that is, the ventilator outlet line end. Because the ventilator tube There is still some 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 the ventilator pipeline. There is a part of the residue on the surface, which forms liquid, which reduces the delivery volume of the drug, and the existing micro-mesh nebulizer is connected to the ventilator tube and the atomization is turned on and the mist is continuously discharged, regardless of whether the patient inhales or exhales. The net nebulizer is working to spray. At this time, part of the aerosol produced by the micro-net 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. A micro-mesh nebulizer combined with a ventilator has a very low delivery volume and serious drug waste.

When the micro-mesh nebulizer is used with a ventilator, it is mainly connected to the ventilator pipeline through a T-shaped three-way connector. The T-shaped three-way connector equipped by the existing micro-mesh nebulizer manufacturers is a right-angle connection. The sprayed aerosol directly hits the pipe wall of the T-shaped three-way joint and the connecting passage of the ventilator, which increases the contact probability of the aerosol with the inner wall of the T-shaped three-way joint pipe, causing a part of the aerosol to hit the inner wall of the pipe to form droplets Unable to deliver to the patient's respiratory tract causes a certain amount of drug loss and reduces the delivery volume.

Patients suffering from lung disease or respiratory disease mostly have abnormal respiratory symptoms such as shortness of breath and shortness of breath. The existing nebulizer has no specific solution for such patients. Nebulized administration is entirely dependent on the patient's spontaneous breathing. , Can not guide patients to standard breathing, no guidance for atomized drug delivery, lack of behavioral habit promotion for patients’ respiratory rehabilitation.
