The invention discloses a steel wire mesh welding process for an inhaler, and a device thereof. The steel wire mesh welding process for the inhaler comprises the steps of S100, machining and forming a bearing body; S200, grabbing the bearing body; S300, placing a steel wire mesh on a bearing part; and S400, welding the steel wire mesh, a second annular wall structure and the bearing part together, so as to fixedly arrange the steel wire mesh on the bearing body. The steel wire mesh welding process for the inhaler, and the device thereof realize integrated arrangement for the steel wire mesh and the bearing body, and the components are high in dimensional accuracy and reliable in connection; and the second annular wall structure has a function of fastening the steel wire mesh and is capable of avoiding a misplacement phenomenon of the steel wire mesh during a connection process, so that the probability of misplacement of the steel wire mesh is almost zero.
Description
technical field [0001] The invention relates to the technical field of medicament inhalers, in particular to a steel wire mesh welding process and device for inhalers. Background technique [0002] Due to its large absorption area and no hepatic first-pass effect, the pulmonary drug delivery route has received extensive attention in the research and development of drug delivery systems, and its clinical application has also developed from the traditional local treatment of asthma to the treatment of systemic diseases. Different from the general route of drug administration, pulmonary drug delivery requires a specific inhalation device to complete the dispersion, atomization and pulmonary delivery of the drug, and the inhalation device plays a key role in the pulmonary drug delivery system. [0003] Inhalers, especially capsule-type dry powder inhalers, when the patient uses the capsule-type dry powder inhaler, they need to press the puncture needle to puncture the capsule co...
