医用超声雾化喷头是医用超声波雾化器的配件之一,喷头作为超声雾化器与呼吸面罩连接的主要部分,由于超声雾化器的喷雾器对雾粒无选择性,经过喷头后的喷雾中的药物颗粒大部分沉积在口腔、喉部等上呼吸道,不能有效治疗下呼吸道疾病;同时,雾化器产生的雾粒大,雾化快,导致患者吸入过多的水蒸气,使呼吸道湿化,呼吸道内原先部分堵塞支气管的干稠分泌物吸收水分后膨胀,加大呼吸道阻力,可能会产生缺氧现象,且超声波雾化器会使药液结成水珠挂在内腔壁上,对下呼吸道疾病效果不佳,对药物需求量大,造成浪费的现象。因此研制新的医用超声雾化喷头减缓雾化器产生的喷雾的流动,并且对雾粒大的雾化药物颗粒再次细化就非常必要。The medical ultrasonic atomizing nozzle is one of the accessories of the medical ultrasonic nebulizer. The nozzle is the main part of the connection between the ultrasonic nebulizer and the breathing mask. Since the nebulizer of the ultrasonic nebulizer has no selectivity to the mist particles, the spray after passing the nozzle Most of the drug particles deposited in the mouth, throat and other upper respiratory tracts cannot effectively treat lower respiratory tract diseases; at the same time, the mist particles produced by the nebulizer are large and atomized quickly, causing patients to inhale too much water vapor and humidify the respiratory tract , the dry and thick secretions in the respiratory tract that partially blocked the bronchi absorb water and expand after absorbing water, increasing the resistance of the respiratory tract, which may cause hypoxia, and the ultrasonic nebulizer will cause the liquid to form water droplets and hang on the inner cavity wall, which is harmful to the The effect of lower respiratory diseases is not good, and the demand for drugs is large, resulting in waste. Therefore, it is very necessary to develop a new medical ultrasonic atomizing nozzle to slow down the flow of the spray produced by the atomizer, and to refine the atomized drug particles with large atomized particles.

After the atomized matter produced by the ultrasonic nebulizer passes through the speed-reducing net, due to the resistance of the speed-reducing net, the speed of the atomized matter will decrease, thereby preventing the patient from inhaling too much water vapor. When the rapid atomized matter impacts the speed-reducing net, the atomized particles will be further refined. There is also a thread inside the outer shell, and a buckle is arranged at the end of the thread, and the buckle is set in the slot of the outer shell The upper end surface of the outer casing is connected with a hollow positioning lock through a thread, and the positioning lock enters the outer casing through a threaded rotation. , the other side of the positioning lock is connected with a gas nozzle, the gas nozzle will increase the pressure of the atomized substance at the outlet, and the atomized particles after refinement will enter the lower respiratory tract more easily after passing through the gas nozzle, which improves and strengthens the Therapeutic effects in lower respiratory diseases.
进一步的,优选的是,所述定位锁可以通过螺纹连接气体喷管。Further, preferably, the positioning lock can be connected to the gas nozzle through threads.
进一步的,优选的是,所述定位锁与所述气体喷管设置成一体式的。Further, preferably, the positioning lock is integrated with the gas nozzle.
进一步的,优选的是,所述气体喷管设置为拉法尔喷管。Further, preferably, the gas nozzle is set as a Rafal nozzle.
本实用新型的有益效果在于:减缓喷雾的流速,避免患者吸入过多的水蒸气,并对喷雾颗粒再次进行细化,使喷雾颗粒直达下呼吸道,改善和增强对下呼吸道疾病的治疗效果。The utility model has the beneficial effects of slowing down the flow rate of the spray, preventing patients from inhaling too much water vapor, refining the spray particles again so that the spray particles can directly reach the lower respiratory tract, and improving and enhancing the therapeutic effect on lower respiratory tract diseases.
