One end of the piston rod 21 is provided with a first disc 211, the bottom surface of the first disc 211 abuts against the bottom surface of the placement groove 11. The middle part of the piston rod 21 is slidably connected in the first sliding groove 12 and the second sliding groove 13. The middle part of the piston rod 21 is provided with a second disc 212, the bottom surface of the second disc 212 abuts against the bottom surface of the first sliding groove 12. The other end of the piston rod 21 extends out of the pen holder 1 and is located outside the pen holder 1. The other end of the piston rod 21 is provided with a pressing handle 213. The spring 22 is arranged in the first sliding groove 12, one end of the spring 22 abuts against the top surface of the first sliding groove 12, and the other end of the spring 22 abuts against the top surface of the second disc 212.

[0046] Specifically, this utility model provides a vaginal suppository delivery pen, including a pen holder 1 and a pushing mechanism 2. The pen holder 1 has a placement groove 11, a first sliding groove 12, and a second sliding groove 13 inside. The placement groove 11 is used to place the suppository 3. The pushing mechanism 2 is slidably connected in the placement groove 11, the first sliding groove 12, and the second sliding groove 13, respectively, and is used to push the suppository 3 out of the placement groove 11. The pushing mechanism 2 includes a piston rod 21 and a spring 22. One end of the piston rod 21 is provided with a first disc 211, and the middle part of the piston rod 21 is provided with a second disc 212. One end of the spring 22 abuts against the top surface of the first sliding groove 12, and the other end of the spring 22 abuts against the top surface of the second disc 212. In the initial state, the bottom surface of the first disc 211 abuts against the bottom surface of the placement groove 11, and the bottom surface of the second disc 212 abuts against the top surface of the first sliding groove 12. The bottom surfaces of the groove 12 abut against each other, and the other end of the piston rod 21 protrudes from the pen holder 1 and is equipped with a pressing handle 213. The operator can push the piston rod 21 upward by pressing the pressing handle 213. At this time, the second disc 212 pushes the spring 22 to compress, and the first disc 211 drives the suppository 3 upward and makes the suppository 3 pass through the top of the pen holder 1 and fall into the patient's lesion. Compared with the traditional method of inserting the suppository 3 with a finger, this application maintains the stability of the patient's vagina during the drug administration process through the setting of the pen holder 1 and the pushing mechanism 2, avoiding the pain and discomfort of the operator during the drug administration process caused by the traditional method of pushing the suppository 3 deeply with a finger, reducing the probability of cross-infection, improving the efficiency of drug administration and the patient's comfort. At the same time, it can effectively control the depth and site of drug administration, so that the suppository 3 can directly, quickly and efficiently reach the correct position, improving the convenience of the operator to deliver the drug into the vagina.

[0047] In some possible implementations, the placement groove 11 includes a silicone protective sleeve 15, which is fitted to the inner wall of the placement groove 11; the bottom of the silicone protective sleeve 15 has a through hole that communicates with the connection hole 14; the top of the silicone protective sleeve 15 has an opening 151; the opening 151 has a cross-shaped structure.

[0048] Specifically, the silicone protective sleeve 15 provides a soft contact surface, preventing the suppository 3 from being squeezed and damaged by the inner wall of the placement groove 11 during upward sliding. At the same time, the silicone protective sleeve 15 can prevent the suppository 3 from contacting the patient's vaginal tissue or secretions during delivery, thus protecting the suppository 3. During use, the suppository 3 is pushed out through the opening 151 at the top of the silicone protective sleeve 15 by the piston rod 21. As an implementation method, the size of the first disc 211 should be less than or equal to the size of the opening 151.

[0049] In some possible implementations, the vaginal suppository pen also includes a marking scale 4, which is disposed on the outer wall of the pen holder 1 along the length of the pen holder 1.

[0050] Specifically, the setting of the scale line 4 makes it easier for medical staff to accurately confirm whether they are currently at the patient's lesion site, so as to accurately deliver the drug to the corresponding depth and location and maximize its efficacy.

[0051] In some possible implementations, the placement groove 11 further includes a recessed platform 111, which is formed on the bottom surface of the placement groove 11. The bottom surface of the first disc 211 abuts against the top surface of the recessed platform 111. The size of the recessed platform 111 is adapted to the size of the first disc 211 so that when the bottom surface of the first disc 211 abuts against the top surface of the recessed platform 111, the top surface of the first disc 211 and the bottom surface of the placement groove 11 are on the same plane.

[0052] Specifically, by setting up the sinking platform 111, the bottom surface of the first disc 211 abuts against the top surface of the sinking platform 111, so that the bottom of the placement groove 11 remains flat and regular.

[0053] In some possible implementations, the vaginal suppository pen also includes a grip portion 5, which includes a support handle 51 and a pull handle 52. The support handle 51 is connected to the bottom of the pen holder 1, and the pull handle 52 is arranged around the periphery of the support handle 51. A movable hole is provided in the middle of the support handle 51, and the other end of the piston rod 21 passes through the movable hole and is located outside the pen holder 1.

[0054] Specifically, with the grip 5 in place, the operator can press the push handle 213 with their thumb while simultaneously using their index and middle fingers to hold the two ends of the pull handle 52, making it more convenient for the operator to operate with one hand.

[0055] In some possible implementations, the diameters of the connecting hole 14 and the second sliding groove 13 are both adapted to the diameter of the piston rod 21, and the diameters of the first disk 211 and the second disk 212 are both larger than the diameter of the piston rod 21; the top of the pen holder 1 has a streamlined structure.

[0056] Specifically, the diameters of the connecting hole 14 and the second sliding groove 13 are both adapted to the diameter of the piston rod 21, facilitating the piston rod 21 to move up and down within the connecting hole 14 and the second sliding groove 13; the diameters of the first disc 211 and the second disc 212 are both larger than the diameter of the piston rod 21, facilitating the first disc 211 and the second disc 212 to abut against the placement groove 11 and the first movable groove 12 respectively in the initial state, thereby realizing the retraction and return of the piston rod 21; the top of the pen holder 1 is designed with a streamlined structure to improve the patient's comfort when moving in the vagina and avoid discomfort caused by sharp corners.
