Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a vaginal drug delivery device suitable for powder or powder injection. Background Art

[0002] Generally, systemic medication not only requires a large amount of medication, but also has a relatively poor local effect and is prone to cause large toxic and side effects. Local administration can not only make up for the defects of systemic administration, but also bring better therapeutic effects. In recent years, intracavitary medication has become a convenient and effective way of medication in clinical practice. For example, cavity drug delivery devices have been used in vaginal medication, nasal medication, and vaginal medication. However, the existing cavity drug delivery devices need to be in direct contact with the human epidermis during use, which is easy to cause human epidermis damage and exogenous infection. In addition, for powder or powder injection drugs, a drug mixing operation needs to be performed before feeding the drug, and the drug mixing operation and the drug delivery operation often require the use of different instruments. In this process, the drug after the drug mixing is completed needs to be transferred to the drug delivery device. The drug is also prone to exogenous infection during the transfer process, affecting the patient's drug effect. Therefore, designing a device that combines the drug mixing operation with the drug delivery operation to achieve convenient and hygienic drug delivery and avoid secondary pollution is a goal that the current industry urgently needs to improve.
