Description
Technical Field
[0001] The utility model relates to the field of medical instruments, in particular to a gynecological disease medication device with improved drug efficacy. Background Art
[0002] Gynecological diseases generally require a special drug delivery device to deliver the drug solution to the patient's vagina. At present, the most commonly used drug delivery device is a syringe structure, which delivers the drug solution to the affected part by pushing the piston. In the above drug delivery device, the drug solution is sprayed out by the pressure of the piston. Since the drug solution is sprayed in a liquid shape and each spray hole sprays the drug solution in almost the same direction, it is easy to gather in certain positions, so the drug delivery area is small, which is not conducive to the patient's rehabilitation treatment.

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0023] like Figure 1 As shown, a gynecological disease drug delivery device for improving drug efficacy comprises a drug cartridge 1, a screw 2, a handle 3, a piston 4 and a cover 15. The drug cartridge 1 is a hollow cylindrical structure with a closed left end and an open right end, and a plurality of drug spraying holes 5 are provided on the side wall near the closed end. Preferably, the closed end of the drug cartridge 1 is in an arc shape that is bent outward. Because the closed end of the drug cartridge 1 is inserted into the patient's vagina facing forward, setting the closed end in an arc-shaped structure can reduce friction, thereby reducing the patient's discomfort. The screw 2 is rotatably located in the drug cartridge 1, and its right end extends out of the drug cartridge 1, specifically as follows: a bearing seat 13 is fixed inside the closed end of the drug cartridge 1, and a second bearing 14 is provided on the bearing seat 13, and the left end of the screw 2 is fixed in the inner ring of the second bearing 14 seat 13. The handle 3 is connected to the right end of the screw 2 and is used to manually drive the screw 2 to rotate. The piston 4 is threadedly mounted on the screw 2 and slides in the cartridge 1 as the screw 2 rotates, so that the liquid medicine in the cartridge 1 is sprayed onto the affected area from the spray hole 5. The cover 15 is detachably covered on the open end of the cartridge 1 and is freely penetrated by the screw 2. The cover 15 seals the open end of the cartridge 1 to prevent external contaminants from entering the cartridge 1 and causing contamination of the liquid medicine. The drug delivery device also includes a drug dispersing mechanism, which is located on the screw 2 and corresponds to the left side of the piston 4, and the drug dispersing mechanism rotates with the sliding of the piston 4 to disperse the liquid medicine in the cartridge 1.
[0024] like Figure 2As shown, the top and bottom of the inner wall of the cartridge 1 are respectively provided with second slide grooves 11 horizontally, and the position of the piston 4 corresponding to the second slide groove 11 is provided with a second protrusion 12 which is in the second slide groove 11 and can slide horizontally along the second slide groove 11. Through the above design, when the handle 3 is manually turned to drive the screw 2 to rotate, the piston 4 cannot rotate due to the restriction of the second slide groove 11 and the second protrusion 12, and can only slide along the screw 2 in the cartridge 1.
[0025] The drug dispersing mechanism includes a first bearing 6, a ring 7 and a blade 8. The inner ring of the first bearing 6 is freely mounted on the screw 2 and corresponds to the position on the left side of the piston 4, and its outer ring is fixedly connected to the piston 4. The ring 7 is freely mounted on the screw 2 and corresponds to the position on the left side of the first bearing 6, and the ring 7 is fixedly connected to the inner ring of the first bearing 6. The screw 2 is horizontally provided with first slide grooves 9 on both sides, such as Figure 3 As shown, a first protrusion 10 located in the first slide groove 9 and capable of sliding horizontally along the first slide groove 9 is provided at the position of the inner wall of the circular ring 7 corresponding to the first slide groove 9. There are a plurality of blades 8, which are evenly distributed on the circular ring 7. Through the above design, when the handle 3 is manually rotated to drive the screw 2 to rotate, the screw 2 rotates through the first slide groove 9 and the first protrusion 10 to drive the circular ring 7 / blades 8 to rotate synchronously to break up the liquid medicine in the cartridge 1. In addition, since the circular ring 7 is fixedly connected to the inner ring of the first bearing 6 and the piston 4 is fixedly connected to the outer ring of the first bearing 6, the circular ring 7 / blades 8 can also slide along the screw 2 under the push of the piston 4, that is, when the screw 2 is rotated, the circular ring 7 / blades 8 can not only rotate but also slide, thereby simultaneously achieving extrusion of the liquid medicine (sliding of the piston 4) and breaking up of the liquid medicine (rotation of the blades 8).
[0026] When the medicine liquid is poured into the medicine cartridge 1, the cover 15 is opened, and the handle 3 is manually rotated to drive the screw 4 to rotate, and the piston 4 is driven to slide out of the medicine cartridge 1, and then the corresponding medicine liquid can be poured into the medicine cartridge 1. Since the medicine spraying hole 5 is a fine hole and the medicine liquid has a certain adhesive force between each other, the medicine liquid poured into the medicine cartridge 1 will not leak out from the medicine spraying hole 5. Then, the piston 4 is pressed back into the inside of the medicine cartridge 1 (ensuring that the second slide groove 11 and the second protrusion 12 are aligned) and the cover 15 is covered again. The medicine cartridge 1 is inserted into the patient's vagina, and the handle 3 is manually rotated in the reverse direction to drive the screw 4 to rotate in the reverse direction. The piston 4 slides along the screw 2 to squeeze the medicine liquid in the medicine cartridge 1 out of the medicine spraying hole 5. At the same time, the blade 8 rotates to disperse the medicine liquid in the medicine cartridge 1, so that the medicine liquid is sprayed out in a semi-atomized state, and each of the medicine spraying holes 5 can spray the medicine liquid in different directions, thereby increasing the coverage area of the medicine liquid and facilitating the efficacy of the medicine.
[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
