Technical Field

[0001] This invention relates to the field of respiratory drug delivery technology, specifically a concealed drug delivery driver. Background Technology

[0002] Respiratory diseases are common and frequently occurring illnesses, primarily affecting the trachea, bronchi, lungs, and pleural cavity. Mild cases often present with cough, chest pain, and impaired breathing, while severe cases can lead to difficulty breathing, hypoxia, and even respiratory failure and death. Nebulized inhalation is a method of treating respiratory diseases by inhaling medications in an aerosol form. It is suitable for various respiratory diseases and some other conditions. Medications include bronchodilators, corticosteroids, and expectorants. It has advantages such as direct targeting of the lesions, rapid onset of action, few systemic adverse reactions, and high patient tolerance. When using nebulized medication, it is important to pay attention to personal hygiene, follow medical advice, and observe reactions.

The protrusions of the top end of the driver nozzle are located on both sides of its bottom suction port to avoid accidental contact by the patient and waste of medicine.

[0007] Preferably, the connecting mechanism includes a sliding buckle groove. The bottom end of the inner wall of the top cover is symmetrically provided with sliding buckle grooves. The sliding buckle groove is provided with a first inclined fastener that is fixedly connected to the top of the connector. The position of the first inclined fastener corresponds to the position of the second inclined fastener. The connector, the first inclined fastener, and the second inclined fastener are an integral structure, which facilitates the patient's disassembly and assembly of the connector and the top cover.

[0008] Preferably, the ends of the first and second inclined fasteners that are far apart from each other are both inclined, the inner wall of the top of the sliding buckle groove is adapted to the inclined surface of the first inclined fastener, the inner wall of the bottom of the sliding buckle groove is snapped to the top of the first inclined fastener, and the sliding buckle groove is also vertically slidably connected to the first inclined fastener, so that the patient can press the top cover.

[0009] Preferably, the locking mechanism includes a locking groove, the surface of the driver nozzle has a locking groove, and the locking groove is located opposite to the suction port of the driver nozzle. Two sets of elastic locking members are fixedly connected to the bottom end of the connector, and the included angle between the elastic locking members is 90 degrees. One set of the elastic locking members is snapped into the locking groove. A set of second inclined fasteners is located at the top of the elastic locking members. A sealing plate is fixedly connected to the bottom end of the connector, and the sealing plate is located on the side where the set of elastic locking members with the second inclined fasteners are fixedly connected. The sealing plate is used to cover the suction port on one side of the driver nozzle. A limiting arc groove is formed on the inner wall of the bottom end of the driver nozzle on the side of the suction port. A limiting arc rod is fixedly connected to one side of the limiting arc groove. The bottom end of the sealing plate is slidably connected to the limiting arc groove. The limiting arc rod and the limiting arc groove are used to limit the sealing plate. A first limiting rod is fixedly connected to the inner wall of the driver nozzle on one side of the locking groove. A second limiting rod is fixedly connected to the inner wall of the driver nozzle on one side of the suction port. A limiting mechanism for sliding and limiting is provided between the driver nozzle and the connecting piece. A third limiting rod is fixedly connected to the inner wall of the driver nozzle, and the third limiting rod is located at the bottom end of a set of elastic locking pieces. The third limiting rod, the atomizing nozzle, and the suction port on one side of the driver nozzle are on the same straight line, which facilitates the patient to lock and unlock the device.

[0013] Preferably, the connector, the elastic lock, and the sealing plate are an integral structure, and the elastic lock is elastic to facilitate locking and unlocking.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] When using the device, the patient first presses the elastic locking element to bend it, causing it to move out of the locking groove. Then, the top cover is rotated 90 degrees counterclockwise. The top cover, through the connecting piece, causes the sealing plate to slide inside the limiting arc groove. Simultaneously, the connecting piece causes the elastic locking element to rotate, and the connecting piece causes the second inclined fastener to slide between the slot and the limiting plate. At this point, another set of elastic locking elements enters the locking groove under its own elasticity. One side of the sealing plate is in contact with the first limiting rod. At this point, the sealing plate no longer blocks the suction port on one side of the actuator nozzle, thus completing the fixation. At this time, the concave part at the bottom of the top cover is aligned with the convex part at the top of the actuator nozzle, and the convex part at the bottom of the top cover is aligned with the concave part at the top of the actuator nozzle. By pressing the top cover, the first inclined fastener slides inside the sliding buckle groove, thus locking the device. The medication inside the medicine container is sprayed out through the atomizing nozzle. After use, pressing the elastic locking piece and rotating the top cover in the opposite direction will seal the suction port on one side of the driver nozzle through the sealing plate, thereby improving patient safety. At the same time, the protrusion at the top of the driver nozzle and the protrusion at the bottom of the top cover are close to each other to prevent accidental contact. The patient can remove the top cover by pinching both sides of the connector to deform it, allowing the patient to replace the medicine container. The patient can also separate the connector from the driver nozzle by pinching the elastic locking piece and pulling the connector upward. This device adopts modular assembly and disassembly, which not only facilitates patient disassembly and replacement but also makes it easy for patients to clean. The small number of modular components also provides operational stability. In addition, this device can prevent accidental contact by patients and improve patient safety.

Arc rod 13 can also limit the movement of sealing plate 11. At the same time, connector 3 drives elastic locking member 9 to rotate. Connector 3 drives second inclined fastener 17 to slide between slot 16 and limiting plate 18. At this time, another set of elastic locking members 9 enters the interior of locking groove 8 under the action of their own elasticity. One side of sealing plate 11 is in contact with first limiting rod 14. At this time, sealing plate 11 no longer blocks the suction port on one side of driver nozzle 1, thus completing the fixation and making it convenient for the patient to lock and unlock the device.

[0031] Please see Figure 7 and Figure 8 In this embodiment, the limiting mechanism includes a slot 16. The top of the driver nozzle 1 is provided with a slot 16.
