[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Example 1
[0020] like Figure 1-3As shown, this application discloses a vaginal medication delivery device, including a first tube 1, a second tube 2 installed at the top of the first tube 1, a top block 5 installed at the top of the second tube 2, a hollow rubber ring 4 installed on the outer side of the second tube 2, a through hole 3 opened in the side wall of the second tube 2, an installation groove 10 opened in the middle of the first tube 1, a movable ring 8 installed in the installation groove 10, a spring 11 installed at the bottom end of the movable ring 8, a movable sleeve 7 installed on the outer side of the movable ring 8, a fixed ring 9 installed at the top end of the movable sleeve 7, a piston 12 installed on the inner side of the first tube 1, and a push-pull rod 13 installed at the bottom end of the piston 12.
[0021] By pulling down the movable sleeve 7, the movable ring 8 and the fixed ring 9 are lowered, placing the tablet between the top block 5 and the fixed ring 9. Releasing the movable sleeve 7 causes the fixed ring 9 to reset under the action of the spring 11, clamping and fixing the tablet. After the first tube 1 enters the vaginal apex, the push-pull rod 13 is pushed, causing the piston 12 to move. Air inside the first tube 1 enters the hollow rubber ring 4 through the through hole 3 on the second tube 2, causing the hollow rubber ring 4 to expand. The hollow rubber ring 4 pushes the tablet out, thus placing the tablet. After the tablet is placed, the push-pull rod 13 is pulled in the opposite direction, causing the piston 12 to move and drawing the air inside the hollow rubber ring 4 back into the first tube 1, completing the contraction of the hollow rubber ring 4.
[0022] like Figure 1-3 As shown, the top block 5 is designed as a frustum, and an arc groove 6 is provided at the top of the top block 5. By setting the top block 5 as a frustum, damage to the vaginal wall can be avoided. By providing an arc groove 6 at the top of the top block 5, the cervix can be protected.
[0023] like Figure 1-3 As shown, the outer side of the fixing ring 9 is designed with an arc shape, and the upper end of the fixing ring 9 is designed with a lower inner side and a higher outer side. The outer side of the fixing ring 9 is designed with an arc shape to avoid scratching the vaginal wall, and the inner side of the upper end of the fixing ring 9 is designed with a lower inner side and a higher outer side to facilitate clamping and fixing the tablet.
[0024] like Figure 1 , 4 As shown, a housing 14 is movably fitted onto the outer side of the first tube 1 near its bottom end. A baffle plate 15 is installed at the upper end of the housing 14. Movable rods 16 are installed through both sides of the housing 14. A vertical surface is opened at the rear end of the movable rods 16, and a horizontally placed insert 17 is installed on the vertical surface. Several vertically equidistant limiting strips 18 are installed at the front end of the first tube 1. The housing 14 and the baffle plate 15 can be adjusted in position along the direction of the first tube 1. Pushing the other end of the movable rod 16 causes the insert 17 to be inserted between the limiting strips 18 at the front end of the first tube 1, thus limiting the position of the housing 14 and the baffle plate 15. By adjusting the position of the housing 14 and the baffle plate 15, the insertion depth of the first tube 1 can be limited.
[0025] like Figure 4 As shown, one end of the insert 17 is provided with a pointed tip that can be inserted between two adjacent limiting strips 18. By providing a pointed tip at one end of the insert 17, it is easy for the insert 17 to be inserted between two adjacent limiting strips 18.
[0026] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0028] The implementation principle of a vaginal medication delivery device according to an embodiment of this application is as follows:
[0029] When loading the tablets, pull down the movable sleeve 7, causing the movable ring 8 and the fixed ring 9 to move downwards, compressing the spring 11, and placing the tablet between the top block 5 and the fixed ring 9. Release the movable sleeve 7, and the spring returns to its original position, causing the fixed ring 9 to clamp the tablet. When it is necessary to adjust the position of the barrier plate 15, slide the housing 14 to the preset depth, push the movable rod 16 to insert the tip of the insert 17 into the gap between the adjacent limiting strips 18, and lock the position of the housing 14 and the barrier plate 15. When delivering the medication, slowly push the first tube 1 along the vagina until the barrier plate is reached. 15. Contact the vulva to prevent further insertion. The frustum structure of the top block 5 guides the first tube 1 through the vaginal folds. The arc groove 6 fits the cervix. At this time, the tablet release operation is performed. Push the push-pull rod 13 to move the piston 12 forward. The air in the first tube 1 enters the hollow rubber ring 4 through the through hole 3. The hollow rubber ring 4 expands and pushes the tablet out. The medicine falls into the fornix. After the medicine delivery is completed, pull the push-pull rod 13 in the opposite direction. The piston 12 draws back the air and causes the hollow rubber ring 4 to contract. The first tube 1 can be easily removed and then cleaned and disinfected.
