Description

Technical Field

[0001] This invention specifically relates to an indwelling cleansing drug delivery device for obstetrics and gynecology, belonging to the field of medical device technology. Background Technology

[0002] In the field of obstetrics and gynecology, maintaining the cleanliness and hygiene of the patient's reproductive tract is one of the important measures to prevent infection and improve treatment outcomes. Traditional cleaning and drug administration methods usually use disposable irrigators or manual cleaning, but these methods have certain limitations, such as incomplete rinsing, inconvenience for long-term placement, easy damage to local tissues, and frequent changes of cleaning supplies increase the risk of infection. Therefore, the medical community is seeking more effective and safer cleaning and drug administration devices to meet clinical needs and improve patient comfort. With the development of medical technology, indwelling cleansing and drug delivery devices have gradually attracted attention. These devices aim to provide a solution that can maintain the cleansing effect for a certain period of time and facilitate drug delivery. Existing indwelling devices mainly include catheters, catheter accessories, and drug delivery systems. Their design usually focuses on ensuring good sealing, preventing infection, and ensuring ease of operation. However, traditional obstetric and gynecological cleansing and drug delivery devices mostly adopt rigid catheter designs. Although rigid catheters are simple in structure and easy to operate, they have many shortcomings in practical applications. First, rigid catheters are prone to friction and damage to the patient's mucosa during insertion or removal, especially when passing through sensitive tissue areas, where the risk of such damage is greatly increased. Second, due to the rigidity of the catheter, its drug delivery coverage is limited and cannot flexibly adapt to the specific needs of different patients, resulting in uneven drug coverage of the drug delivery area and affecting the treatment effect. To address the aforementioned technical issues, a gynecological and obstetric indwelling cleansing drug delivery device is proposed. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a gynecological indwelling cleansing and drug delivery device. This device utilizes a flexible, expandable structure to conform to vaginal folds, making it easier to insert and fix the drug within the patient's body. Furthermore, the flexible expandable mechanism facilitates drug delivery or cleansing, ensuring that the drug reaches all points within the body and improving drug coverage. A gynecological indwelling clean drug delivery device includes a drug delivery mechanism, a collection mechanism, and a detection mechanism. The drug delivery mechanism is located inside the patient's body and is used for administering drugs internally. The collection mechanism is installed on one side of the drug delivery device, and the collection mechanism is used to collect and discharge the waste liquid after cleaning; The detection device is installed on one side of the drug delivery device and is used to scan the patient's body.

[0034] Working principle: In the initial state, the expander 12 is straight, forming a columnar shape with the hollow sphere 11 and the fixing shell 21. The hollow sphere 11 is inserted into the patient's body as the tip. After reaching the drug delivery area, it stops moving. Affected by body temperature, the expander 12 deforms and bends, thus making the expander 12 into an umbrella shape to open the vagina. The expander 12 fits against the vaginal folds, opening the drug delivery area while simultaneously fixing the expander 12 in place. The vaginal folds are scanned by the micro OCT probe 31 to generate a 3D drug delivery path planning map, and the thin-film driven micropump 15 distributes the drug delivery to each expander. The drug delivery volume is delivered by the opening 12. The drug delivery pump is connected to the drug delivery tube 13, and the drug solution is injected into the membrane-driven micro pump 15. The membrane-driven micro pump 15 delivers the drug solution into the flexible conduit 121 and sprays it out through the micro nozzle 122, thereby delivering the drug to various points in the body. During cleaning, the air pump 24 inflates the air bag 22 to seal the cleaning area. The cleaning solution is injected through the drug delivery tube 13 and sprayed out through the micro nozzle 122. The waste liquid generated after cleaning is blocked by the air bag 22, enters the fixed shell 21 through the collection hole 27, and then is discharged through the discharge pipe 23.
