This invention relates to drug nebulizers, specifically disclosing a wearable respiratory medicine drug nebulizer, comprising a housing and a handle fixedly connected to its lower end. The housing has an internal air collecting tube and an external exhaust port extending into the air collecting tube, with a breathing mask connected to the exhaust port. An elastic cord for wearing the breathing mask on the patient's face is connected to the housing, and a medicine bottle is mounted at the upper end of the housing. An air compressor is installed inside the housing. The air collecting tube is connected to the medicine bottle via an air delivery tube, and the middle part of the air delivery tube is connected to the exhaust end of the air compressor. This invention results in fewer droplets in the breathing mask during patient exhalation, reducing medication waste; and more droplets in the breathing mask during patient inhalation, facilitating the inhalation of more medication-containing droplets, thereby improving medication utilization.

The invention discloses a static magnetic field modified waxy corn starch stabilized astaxanthin-loaded oil-in-water Pickering emulsion as well as a preparation method and application thereof, and belongs to the technical field of emulsion preparation. The problems that the bioavailability of astaxanthin is low, and the stable Pickering emulsion is difficult to form due to strong hydrophilicity and weak interfacial activity of natural starch are solved. Waxy corn starch subjected to static magnetic field treatment and gelatinization is used as a water phase, corn oil containing astaxanthin is used as an oil phase, and the two phases are mixed to obtain the emulsion. According to the invention, gelatinized modified starch is used as an emulsifier; meanwhile, the static magnetic field treatment changes short-range and long-range ordered structures of waxy corn starch, improves the relative crystallinity, expansibility, solubility and gelatinization characteristics of the waxy corn starch, improves the emulsifying activity and emulsion stability, regulates the release rate of free fatty acid, and improves the bioaccessibility of astaxanthin. The emulsion provided by the invention has the advantages of small liquid drops, high rheological stability, heat resistance, ultraviolet radiation resistance and high salt ion resistance.

The utility model belongs to the field of humidifiers, and provides a humidifier spray pipe device which comprises a main machine, a water storage cavity and an atomization working cavity are arranged in the main machine, an atomization device and a water pump used for conveying water flow from the water storage cavity to the atomization device are arranged in the atomization working cavity, and a spray pipe assembly is arranged at the top of the atomization device. The spraying pipe assembly comprises a water collecting tee joint, a blocking plate is arranged at the bottom end of the water collecting tee joint, a connecting pipe communicated with the atomization device and a water return pipe communicated with the water storage cavity are arranged on the blocking plate, an elbow is arranged at the top of the connecting pipe, and the length of the elbow is smaller than that of the water collecting tee joint. A baffle is arranged at the end, opposite to the end of the elbow, of the water collecting tee joint. The elbow is arranged in the water collecting tee joint, on one hand, the spraying distance between mist spray and the main machine can be prolonged, mist drops falling on the main machine can be reduced, and on the other hand, redundant mist drops can be recycled.
