Description

Technical Field

[0001] This invention relates to a drug delivery device, particularly a portable drug delivery device for gynecological use, and also to a method of using the drug delivery device, especially a method of using a portable drug delivery device for gynecological use, belonging to the field of drug delivery device technology. Background Technology

[0002] In the prior art, such as the gynecological nursing drug delivery device disclosed in application number CN202210987118.2, a drug tube and a push rod movably inserted through the upper half of the drug tube are included. A piston is provided at one end of the push rod located inside the drug tube. The piston is interference-fitted with the inner wall of the drug tube. A rotating ring is rotatably sleeved on the outer circumference of the drug tube. A limit component is provided between the rotating ring and the drug tube. A drug discharge port is opened on the inner wall of the drug tube. Several connecting posts are fixedly connected between the top wall and the bottom wall of the drug discharge port. A drug delivery chamber is opened in the rotating ring corresponding to the position of the drug discharge port. The drug delivery chamber communicates with the drug discharge port.

[0003] This invention allows the operator to push the plunger to dispense the medication onto the vaginal wall, and rotate the plunger to make the rotating ring rotate. The protrusion drives the medication to move, thus allowing the medication to be evenly applied to the patient's vaginal wall, preventing medication accumulation and improving the treatment effect.

[0004] Although existing technologies can achieve portable drug delivery, they are not convenient in actual operation. In addition, the inability to adjust the dosing rod leads to incomplete drug delivery. Furthermore, the dosing cannot achieve automated quantitative dosing and does not have a good stirring effect on the drug solution. Therefore, a portable gynecological drug delivery device and its usage method are designed to solve the above problems. Summary of the Invention

[0026] By activating the regulating motor 2 to drive the piston plate assembly, the first one-way valve assembly connects with the suction rod 7, drawing the medicine from the medicine storage chamber 6 into the medicine suction chamber 1. Then, it flows into the medicine addition pipe 12 through the second one-way valve assembly. The medicine addition pipe 12 can be adjusted by adjusting the angle adjustment assembly, and the medicine can be fully added to the vagina through the side outlet hole 13. In addition, a stirring assembly is provided to achieve good stirring function and prevent the solution from settling in the medicine storage chamber 6.
