Description

Medical net type atomizer

Technical Field

The utility model relates to the technical field of atomizers, in particular to a medical mesh type atomizer.

Background

The medicine is directly sprayed to the respiratory tract to cover the whole respiratory tract mucosa, which is an important method for preventing and treating respiratory diseases, and is another administration method except oral administration and injection at present. The method of atomization administration can treat respiratory diseases and can be used as an administration method for diseases such as cardiovascular diseases, endocrine diseases and the like.

For example: vaccine is administered through respiratory tract, cardiac emergency respiratory tract, insulin is administered through respiratory tract, antibiotic is administered through respiratory tract, interferon is administered through respiratory tract, etc. Therefore, as an important therapeutic medical instrument for respiratory diseases, nebulizers are mainly used in the form of jet nebulizers, ultrasonic nebulizers and mesh nebulizers. Through the method of atomizing administration, the aim that pursues jointly is to improve delivery total amount and delivery efficiency to and how to aim at different crowds and the treatment demand of different diseases, accomplish that atomizing speed is adjustable, atomizing diaphragm is interchangeable, solves the requirement that current atomizer can not reach, thereby reduced the consumptive material cost.

The defects and shortcomings of the prior art are mainly as follows:

the existing jet atomizer and ultrasonic atomizer cannot enable airflow to impact liquid medicine to be atomized due to the atomization principle of the jet atomizer on the lower liquid medicine surface, the ultrasonic atomizer cannot vibrate to generate atomized liquid due to the vibration component, and the two atomizers can inevitably cause about 1mL-2mL of liquid medicine to remain, so that the waste of atomized medicine is caused, and difficulty is brought to the cleaning of the atomizers.

In the existing jet atomizer, due to the atomization principle, atomized particles are affected by the problems of air flow size and the internal structure of the atomizer, so that the atomized particles are uneven and repeatedly impact on a baffle plate, and the jet atomizer is not suitable for unstable macromolecule and liposome atomized liquid; due to the atomization principle, the ultrasonic atomizer has larger atomized particles, larger output fog and excessive humidification, lower liquid oxygen concentration of the sucked fog and increases respiratory resistance. At the same time, ultrasonic atomization can raise the temperature of the liquid medicine, and highly viscous liquid, suspension and heat sensitive medicines are not suitable for an ultrasonic atomizer.

The existing jet atomizer or ultrasonic atomizer is often provided with a mask, a mouthpiece or a breathing machine for use when in use, the atomizer is in a continuous working state, and generated aerosol is directly discharged or discharged along with expiration, so that a large amount of medicine aerosol exists in an atomization environment, the effect of atomized medicine is reduced due to waste, pollution is caused by the medicine aerosol, and the risk of exposure and injury of related personnel is caused; when the existing jet atomizer or ultrasonic atomizer is used, the atomizing pipeline is a longer hose, so that the cleaning is difficult, and bacteria are easy to breed. Meanwhile, the atomized liquid level is positioned below the mist outlet, so that the risk of pollution caused by condensed water exists, and if the atomized liquid level is not cleaned in time, repeated infection of respiratory tract can be caused.

The atomization therapy is often used in an ICU ward and is often matched with a breathing machine or an anesthesia machine, and because the breathing machine needs to monitor the breathing state of a patient, a gas passage formed by a breathing pipeline and the respiratory tract of the patient is required to be airtight, the atomizer matched with the breathing machine or the anesthesia machine is required to be used, so that the air pressure in the pipeline of the breathing machine is not allowed to be influenced, otherwise, the breathing machine is easy to misjudge or alarm. Jet atomization requires a drive gas source to be provided by one of the branches of the ventilator's gas flow, most ventilators provide a drive pressure to the atomizer of < 15psi, less than compressed air or oxygen (50 psi) commonly used in hospitals, and the reduction in drive pressure reduces the efficiency of the jet atomizer, producing an increase in aerosol diameter, thereby reducing the total amount of aerosol reaching the lower respiratory tract. However, some respirators, such as feixuer, michigan, and the like, are not equipped with an atomization function, and can only be driven by an additional compressed air source, and the external air flow can increase the tidal volume and influence the air supply of the respirators. The basic airflow is increased, and the bad triggering of the patient is easily caused. If the external air source is compressed oxygen, the actual inhaled oxygen concentration is higher than the set oxygen concentration of the breathing machine, and the breathing of the patient with slow pulmonary resistance is inhibited. The micro-grid atomizer extrudes the liquid medicine from the micro-grid to form aerosol by means of micro-grid vibration of the micro-grid atomizing sheet, and local air pressure is not affected, so that the micro-grid atomizer is the most suitable atomizer in the application scene of the breathing machine or the anesthesia machine. The micro-grid atomizer is matched with a breathing machine for application, is mainly placed at the air inlet end of a breathing machine humidification tank pipeline or the air inlet pipeline of a patient of a breathing machine pipeline Y-shaped connector, namely the air outlet pipeline end of the breathing machine, but the traditional micro-grid atomizer is connected with the breathing machine pipeline and continuously performs continuous mist outlet after atomization is started, no matter the patient inhales and exhales, the micro-grid atomizer is sprayed during work, at the moment, part of medicine mist generated during the work of the micro-grid atomizer can enter the respiratory tract along with the inhalation of the patient, and the other part of medicine mist can be wasted in the breathing machine pipeline along with the exhalation of the patient, so that the application delivery quantity of the traditional micro-grid atomizer matched with the breathing machine is very low, and the medicine waste is serious.

According to the updated consensus and guidelines in recent years, atomized particles can effectively enter the lower lung at the diameter of 3um-5um, the traditional atomizing device can not well control the atomized particles in the range, the atomized particles of the ultrasonic atomizer are concentrated at the diameter of 5um-10um, and the particles of the size can be settled in the upper airway, so that the traditional atomizing device can not well perform the drug delivery function on the diseases requiring lower lung or bronchus drug delivery, such as asthma, slow pulmonary obstruction and the like; the jet atomized particles are relatively dispersed, 50% of the atomized particles of part of the jet atomizing device are smaller than 1um, and the particles cannot be settled in the lung and can be discharged along with the exhalation phase. Therefore, when treating different diseases of the upper airway and the lower airway, an atomization device with an interchangeable atomization module is needed, and waste of consumable materials is reduced.

In the existing micro-grid atomizers on the market, the mist outlet direction is always downward, and partial liquid drops are settled below the mist storage tank to form accumulated liquid due to gravity and the movement direction of atomized liquid drops.

The micro-grid atomizer on the market at present usually has a strict inclination angle limitation when in use, such as a Payi micro-grid atomizer and the like, and cannot be normally used when facing to the situation that a user needs to perform horizontal atomization.

The micro-grid atomizer on the market can not directly ventilate oxygen in atomization, and when the micro-grid atomizer is used, a patient needs to independently remove the atomization device after inhaling to exhale, or directly exhale to cause atomized aerosol to be exhaled together, so that the micro-grid atomizer is inconvenient to use.

Based on the reasons, the utility model is significant in an adjustable and replaceable medical mesh type atomizer.
