Description
技术领域technical field
本实用新型属于医疗器械领域,涉及一种药物雾化吸入装置。The utility model belongs to the field of medical equipment and relates to a drug atomization inhalation device.
背景技术Background technique
经雾化吸入给药可以将药物直接靶向病灶部位以增强疗效,减少不良反应,现在已经广泛应用于支气管肺部疾病特别是支气管哮喘、肺癌等疾病的治疗和研究,效果显著。同时,由于肺部吸收面积大,经支气管肺部给药也是促进药物全身吸收的重要途径之一,该方法不仅操作简便,而且减少了病人肌肉及静脉注射的不便和痛苦。因此对经支气管肺部给药的研究具有广阔的发展前景。Administration by atomization inhalation can directly target the drug to the lesion to enhance the curative effect and reduce adverse reactions. It has been widely used in the treatment and research of bronchopulmonary diseases, especially bronchial asthma, lung cancer and other diseases, and the effect is remarkable. At the same time, due to the large absorption area of the lung, transbronchial pulmonary administration is also one of the important ways to promote the systemic absorption of the drug. This method is not only easy to operate, but also reduces the inconvenience and pain of the patient's muscle and intravenous injection. Therefore, the research on bronchopulmonary drug delivery has broad prospects for development.
目前临床常用的雾化吸入装置包括:蒸汽雾化吸入器和超声雾化吸入器。蒸汽雾化吸入器或超声雾化吸入器一般由雾化器和药物雾化吸入配套装置两个部分组成。雾化器主要通过蒸汽雾化或超声雾化等提供动力,雾化吸入配套装置由咬嘴和药物放置管两个部分组成,药物溶液放置在药物放置管中,药物放置管的一端与雾化器连接,另一端直接连接咬嘴。由雾化器产生动力,带动气流将药物溶液喷射成雾滴,患者通过咬嘴直接吸入药物。因此,气流压力不能太小,否则动力太小,不能将雾滴有效喷出。由于药物放置管,是一个容积相对小的狭短管道,这样气流将药物溶液喷射成雾滴,经过很短的路径就通过咬嘴直接喷出去了,患者如果不咬紧咬嘴,药物会喷到空气中造成浪费,另外喷射时的气流压力和喷出的雾滴直接就到了口鼻局部,由于没有地方储藏缓冲造成鼻、口、咽局部的药雾弥漫,病人感觉缺氧和呼吸困难。所以,这些雾化吸入装置在使用时尚存在一些问题:(1)雾化吸入装置所喷出的气流压力过大、雾化时鼻、口、咽局部的药雾弥漫,造成病人不适和通气障碍;(2)为了药物的充分吸入,往往需要病人将雾化吸入装置的咬嘴部位包紧,因此增加了病人的额外用力,同时也不利于病人的通气及二氧化碳的排出,从而导致呼吸困难加重。因此,在使用时病人耐受性较差,尤其是对于不能主动配合的婴幼儿和难以配合的重度呼吸功能衰竭病人更是如此。因此不少病人拒绝雾化吸入治疗,从而难以达到药物理想的疗效。At present, commonly used clinical nebulization inhalation devices include steam nebulization inhalers and ultrasonic nebulization inhalers. Steam atomization inhalers or ultrasonic atomization inhalers are generally composed of two parts: a nebulizer and a drug atomization inhalation supporting device. The atomizer is mainly powered by steam atomization or ultrasonic atomization. The atomization inhalation supporting device is composed of a mouthpiece and a drug placement tube. The drug solution is placed in the drug placement tube, and one end of the drug placement tube is connected to the atomizer. The other end is directly connected to the mouthpiece. The power is generated by the nebulizer, which drives the airflow to spray the drug solution into mist droplets, and the patient directly inhales the drug through the mouthpiece. Therefore, the airflow pressure cannot be too small, otherwise the power will be too small to effectively eject the droplets. Since the drug placement tube is a narrow and short pipe with a relatively small volume, the airflow sprays the drug solution into mist droplets, which are directly sprayed out through the mouthpiece after a short path. If the patient does not bite the mouthpiece tightly, the drug will Spraying into the air causes waste. In addition, the airflow pressure and the sprayed mist droplets directly reach the mouth and nose. Because there is no place to store and buffer, the medicine mist in the nose, mouth, and pharynx is diffused, and the patient feels hypoxia and difficulty breathing. . Therefore, there are some problems in the use of these atomized inhalation devices: (1) the pressure of the airflow ejected by the atomized inhalation device is too large, and the local drug mist in the nose, mouth, and pharynx is diffused during atomization, causing discomfort and ventilation obstacles to the patient (2) In order to fully inhale the drug, the patient is often required to tightly wrap the mouthpiece of the atomization inhalation device, which increases the patient's extra effort, and is also not conducive to the patient's ventilation and carbon dioxide discharge, resulting in aggravated dyspnea . Therefore, the patient's tolerance is poor when used, especially for infants who cannot actively cooperate and patients with severe respiratory failure who are difficult to cooperate. Therefore many patients refuse nebulization inhalation treatment, thus be difficult to reach the desired curative effect of medicine.
