Description

Technical Field

[0001] This utility model relates to a drug delivery device, specifically an atomizing drug delivery device, belonging to the technical field of gynecological drug delivery atomizers. Background Technology

[0002] Nebulized drug delivery is a common gynecological treatment method. It involves placing anti-inflammatory and antibacterial medications into a nebulizer, heating it, and then delivering the atomized gas into the vagina to treat gynecological diseases. Gynecological nebulization breaks down medications into tiny particles that directly target the affected areas, such as the vagina, cervix, or pelvic cavity, effectively killing bacteria and providing anti-inflammatory and antibacterial effects. Nebulized drug delivery allows anti-infective drugs to be delivered directly to the lesion, increasing local drug concentration and reducing systemic side effects. Gynecological nebulization can also promote blood circulation in the vagina and cervix, accelerate tissue repair, and aid in wound healing.

[0003] A known Chinese invention (publication number: CN119055939A) discloses a nebulizer for drug delivery, which is designed as a nebulizer consisting of three parts: a main unit, a liquid storage structure, and a replacement head structure. The main unit is a universal fixture used to provide power. The liquid storage structure is used to add or replace the drug according to usage needs. The replacement head structure is in direct contact with the user. The replacement head connector is a disposable and replaceable structure. In use, the liquid storage structure is placed inside the main unit and the replacement head structure, and the head support is inserted into the inner liner of the main unit and rotated to complete the connection between the nebulizer and the main unit.

[0004] When the replacement head is connected to the main unit, the connection point is designed in the middle of the entire device. While this layout optimizes the overall structure of the device, it also presents certain challenges: Because the connection point is in the middle, the length of the replacement head is correspondingly shortened. This means that during use, the main unit may come into direct contact with the user. Since the main unit is a non-replaceable part, this could lead to contamination of the main unit. Therefore, a nebulized drug delivery device is proposed. Utility Model Content
