Abstract
Description
Technical Field
[0001] This utility model relates to the field of dry powder flow rate monitoring technology, and in particular to a flow rate monitoring device for a dry powder inhaler. Background Technology
[0002] A dry powder inhaler is a device that delivers medication in dry powder form to the respiratory tract. It primarily relies on the patient's inspiratory airflow to disperse and aggregate the drug powder from the storage container, forming inhalable microparticles that ultimately deposit in the lungs to exert their therapeutic effect. Using a flow rate monitoring device helps monitor the inhaler's performance at various flow rates and measures the patient's inspiratory airflow rate in real time, ensuring that the medication effectively reaches the lungs to exert its therapeutic effect.
[0003] Traditional dry powder inhalers typically have a fixed cross-section for the airflow monitoring device, which cannot adjust the size of the airflow channel according to the needs of different patients. This results in the medication not being fully utilized and reduces the accuracy of treatment. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a flow rate monitoring device for a dry powder inhaler, which aims to improve the problem that the traditional flow rate monitoring device for dry powder inhalers cannot adjust the airflow channel, thus reducing the accuracy of treatment.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A flow rate monitoring device for a dry powder inhaler includes a dry powder storage tank, a nozzle on the outer wall of the dry powder storage tank, an inhalation channel fixedly connected inside the dry powder storage tank, a partition fixedly connected to the outer wall of the inhalation channel, a gear ring rotatably connected to the outer wall of the partition, a rotating handle fixedly connected to the outer wall of the gear ring, a transmission gear meshing with the inner wall of the gear ring, a rack meshing with the outer wall of the transmission gear, a closing plate fixedly connected to the outer wall of the rack, and a ventilation component provided on the outer wall of the partition for ventilating the inhalation channel.
[0007] Preferably, the ventilation assembly includes an airflow channel, the outer wall of which is fixedly connected to the outer wall of the partition, and a flow velocity port is provided inside the airflow channel.
[0008] Preferably, the internal rotatable connection of the transmission gear is to the outer wall of the partition.
[0009] Preferably, the outer wall of the rack is slidably connected to the outer wall of the partition.
[0010] Preferably, a monitoring box is fixedly connected to the left side of the airflow channel, an electrical box is fixedly connected to the lower interior of the monitoring box, and a monitoring instrument body is fixedly connected to the left inner wall of the monitoring box.
[0011] Preferably, a support platform is fixedly connected to the outer wall of the monitoring box, a hydraulic cylinder is rotatably connected to the outer wall of the support platform, a control board is fixedly connected to the output end of the hydraulic cylinder, and a rotating rod is fixedly connected to the inside of the left side of the control board.
[0012] Preferably, the control panel has a display screen inside.
[0013] Preferably, the outer wall of the rotating rod is rotatably connected to the inside of the left side of the monitoring box.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this invention, pushing the rotating handle drives the gear ring to rotate, and then the transmission gear slides with the rotation of the gear ring. Subsequently, the rack slides under the drive of the transmission gear, ultimately achieving the opening and closing adjustment of the flow rate port by the closing plate. This allows for adaptation to different patients' inspiratory abilities, improving treatment accuracy. 2. In this invention, the monitoring instrument body is activated by the electrical box, and the hydraulic cylinder drives the control plate to rotate. The rotating rod then rotates with the control plate, ultimately closing the monitoring box and allowing the monitoring data to be observed on the display screen. This effectively prevents dust, impurities, and other foreign objects from entering the flow rate monitoring device, improving monitoring accuracy. Attached Figure Description
