Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a spray-type drug application device for clinical obstetrics and gynecology. Background Art

[0002] Gynecological and obstetric clinical treatment covers a wide range of diseases and conditions, including gynecological inflammation, postpartum repair, uterine diseases, etc. There are various treatment methods for these diseases, and common treatment methods include medication, surgery, and physical therapy. In terms of medication, obstetricians and gynecologists usually need to deliver the drugs directly to the lesion site to improve the efficacy of the drugs and reduce the impact on other parts. Traditional gynecological and obstetric drug treatments are mostly oral or topical, but these methods often have problems such as incomplete drug absorption and uneven treatment effects, which affect the efficiency of treatment and the comfort of patients.

[0003] In clinical obstetrics and gynecology, jet-type medication devices are widely used for precise drug delivery, especially in the treatment of diseases in the vagina, cervix and other parts of the body. Jet-type medication devices can spray drugs directly into the diseased area, avoiding drug waste and systemic side effects. Traditional jet-type medication devices mostly rely on manual or mechanical pumps to deliver drugs, and use a spray head to atomize the drugs so that they can better penetrate into the diseased tissue. However, existing jet-type medication devices still have some shortcomings, especially in the uneven distribution of drugs during treatment, complex equipment operation, and poor patient comfort, which limit their clinical application.

[0004] Although the existing jet-type drug delivery device can achieve precise drug delivery, in actual applications, the drug spraying of some drug delivery devices is somewhat uneven, and it is difficult to ensure that the drug solution can evenly cover the target area. In addition, during the use of traditional equipment, patients will feel uncomfortable, especially during the expansion process. Traditional devices fail to effectively reduce the pressure caused by the expansion, resulting in increased discomfort for patients. Therefore, a jet-type drug delivery device for clinical obstetrics and gynecology is proposed to address the deficiencies in the existing technology. Summary of the invention

[0045] The present invention summarizes that the expansion plate 1 701 is made of high-strength medical-grade engineering plastics, and has the characteristics of light weight and high strength. At the same time, its surface is precisely processed and polished to reduce friction and stimulation to vaginal tissue. The outer periphery of the expansion plate 1 701 is provided with an expansion plate 2 702 made of flexible medical silicone rubber material, which can effectively reduce pressure and stimulation to tissues during the expansion process and improve the comfort of patients.

[0046] Working principle: When in use, the camera 14 is first installed at the front end of the tube body 13. By pressing the two moving rods 501, the moving rods 501 drive the L-shaped block 502 to move, so that the L-shaped block 502 will move along the sliding rod 503 and apply a squeezing force to the spring 504. Then, the camera 14 is abutted against the end of the tube body 13, and then the moving rod 501 can be loosened. After the moving rod 501 is loosened, the spring 504 loses the squeezing force of the L-shaped block 502, thereby applying a force to the L-shaped block 502. After the L-shaped block 502 is subjected to the force, it can slide into the camera 14, so that the camera 14 is assembled at the front end of the tube body 13.

[0047] Then, the medicine storage bottle 9 is placed on the top of the mounting block 8, and then the electric push rod 601 is started, and the electric push rod 601 drives the horizontal plate 602 to move upward together. When the horizontal plate 602 moves, the wedge block 603 on the front side of the horizontal plate 602 slides in the wedge groove 604 opened inside the moving plate 605, so that the two moving plates 605 move horizontally in opposite directions. Then, the medicine storage bottle 9 is placed on the top of the mounting block 8, and then the electric push rod 601 is started again, so that the electric push rod 601 drives the horizontal plate 602 to move downward, so that the two moving plates 605 move toward each other so that the arc plate 611 contacts the medicine storage bottle 9, so that the medicine storage bottle 9 is fixed on the top of the mounting block 8;

[0048] Then the medical staff can hold the handle 1, start the device, slowly insert the camera 14 into the patient's vagina, and then observe the vagina through the camera 14. After determining the spraying site, the medical staff can rotate the rotating wheel 201. When the rotating wheel 201 rotates, it will drive the worm 202 to rotate together. Because the worm 202 is meshed with the worm wheel 203, when the worm 202 rotates, the worm wheel 203 will rotate together, thereby driving the rotating rod 204 to rotate;

[0049] The rotating rod 204 is connected to the bidirectional threaded rod 301, so that when the rotating rod 204 rotates, the bidirectional threaded rod 301 is driven to rotate together. During the rotation of the bidirectional threaded rod 301, the two threaded movable rings 302 on the outer periphery of the bidirectional threaded rod 301 will move horizontally along the bidirectional threaded rod 301 due to the rotation of the bidirectional threaded rod 301. When the movable ring 302 moves, the movable ring 302 will drive the connecting block 1 303 to move together. When the connecting block 1 303 moves with the movable ring 302, the distance between the connecting block 1 303 and the connecting block 2 305 changes, so that the rotating rod 304 is rotated. Then, when the rotating rod 304 rotates, a force is applied to the connecting block 2 305, so that the connecting block 2 305 drives the slider 306 to move, and the limit blocks 307 on the left and right sides of the slider 306 slide in the limit grooves 308 provided in the tube body 13, thereby driving the expansion plate 1 701 to slide and expand the inside of the vagina.

[0050] Then, press the button on the rear side of the mounting block 8 to control the protective shell 12 to start extracting the liquid medicine in the medicine storage bottle 9, and the extracted liquid medicine will be diverted to each infusion pipe 401, and the liquid medicine will enter the multiple nozzles of the medicine spray plate 403 through the infusion pipe 401 and the connecting end 402, and the liquid medicine will be sprayed into the vagina through the nozzle, thereby completing the spraying work.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
