The sleeve pipe is connected with the inner pipe 1 in a damping rotation mode, and specifically, the damping rotation mode can be as follows: the roughness of the contact surface between the sleeve and the inner tube 1 is increased during processing and manufacturing, so that the sleeve is prevented from being extruded by human tissues on the vaginal wall to rotate after entering the vagina during administration.

When the medicine needs to be taken, the medicine can be gel, liquid or paste, the medicine is filled in the closed area between the piston 15 and the inner tube 1, the sleeve enters the vagina of a patient, the sleeve does not rotate because the sleeve is rotationally connected with the damping between the inner tube 1, the adjacent upper and lower sections of second sleeve 7 are marked as a second sleeve 7A and a second sleeve 7B for the sake of clear and concise expression, when the sleeve reaches an affected part, the piston 15 is driven, the piston 15 slides towards the tube bottom direction of the inner tube 1 (namely process sliding), the guide piece slides in the guide groove 4 and the second sliding groove simultaneously, after the guide piece enters the second process deviation groove 11 of the second sleeve 7A, because the second process deviation groove 11 (belonging to the second sleeve 7A) and the guide groove 4 are arranged at a certain angle (the second process deviation groove 11 is obliquely arranged), the guide piece slides in the second process deviation groove 11 and drives the second process deviation groove 11 (the second sleeve 7A) to rotate, the second process deviation groove 11 drives the second sleeve 7A to rotate, so that the medicine outlet holes 5 on the second sleeve 7A are in alignment communication with the second communication holes 20 on the second sleeve 7 (namely, the second sleeve 7B), namely, the medicine outlet holes 5 on the second sleeve 7A are in alignment communication with the corresponding medicine feeding holes 3, at this time, the medicine feeding holes 3 in the medicine feeding structure 2 (corresponding to the second sleeve 7A) in the layer are opened (communicated with the outside), and because the medicine feeding holes 3 in the medicine feeding structures 2 of other layers are not opened and are still in a closed state, the medicine flows out from the medicine feeding holes 3 in the medicine feeding structure 2 in the layer, the medicine flows into an affected part through the second communication holes 20 (belonging to the second sleeve 7B) and the medicine outlet holes 5 (belonging to the second sleeve 7A), when the guide piece enters the second process straight groove 12 (belonging to the second sleeve 7A) from the second process deviation groove 11, the medicine outlet holes 5 on the second sleeve 7A are in full alignment (concentric) with the corresponding medicine feeding holes 3, because the piston 15 still slides in the process, the medicine continuously flows to the affected part through the medicine feeding hole 3 (belonging to the inner tube 1), the second communication hole 20 (belonging to the second sleeve 7B) and the medicine outlet hole 5 (belonging to the second sleeve 7A), and meanwhile, the second process straight groove 12 on the section of the second sleeve 7 (namely the second sleeve 7A) is communicated with the second process deviated groove 11 on the lower section of the second sleeve 7 (namely the second sleeve 7B).

When the guiding piece enters the second progress deviation groove 11 on the second sleeve 7 (namely the second sleeve 7B) at the lower section, the second progress deviation groove 11 (belonging to the second sleeve 7B) is driven to rotate, the second progress deviation groove 11 (belonging to the second sleeve 7B) drives the second inner boss 18 (belonging to the second sleeve 7B) to rotate, the second inner boss 18 (belonging to the second sleeve 7B) rotates to ensure that the second communication hole 20 (the second inner boss 18 belonging to the second sleeve 7B) is gradually dislocated with the administration hole 3 in the upper layer administration structure 2 (corresponding to the second sleeve 7A), the administration hole 3 in the upper layer administration structure 2 (corresponding to the second sleeve 7A) is blocked by the second inner boss 18 (namely the second inner boss 18 of the second sleeve 7B) again, and simultaneously, the rotation of the second inner boss 18 (namely the second inner boss 18 of the second sleeve 7B) drives the second sleeve 7 (namely the second sleeve 7B) to rotate, the second sleeve 7 (i.e. the second sleeve 7B) of the section drives the medicine outlet 5 (belonging to the second outer boss 19 on the second sleeve 7B) to be in contraposition communication with the corresponding medicine feeding hole 3 gradually, at this time, the medicine feeding hole 3 (corresponding to the second sleeve 7A) in the upper layer medicine feeding structure 2 is sealed, the medicine feeding hole 3 (corresponding to the second sleeve 7B) in the layer of medicine feeding structure 2 is opened, since the administration hole 3 of the administration structure 2 of the other layer is not opened and still in the closed state, the medicine will flow out from the administration hole 3 (corresponding to the second sleeve 7B) of the administration structure 2 of the layer, and the second communication hole 20 (belonging to the second sleeve 7 of the lower section relative to the second sleeve 7B) and the medicine outlet hole 5 (belonging to the second sleeve 7B) will flow into the affected part, and the movement of the rest of the second sleeve 7 under the sliding action of the guiding member is the same as the above movement.

The arrangement is that the medicine feeding holes 3 in the adjacent upper and lower layers of medicine feeding structures 2 are closed, the medicine feeding holes 3 in the lower layer of medicine feeding structure 2 are opened at the same time of closing the medicine feeding holes 3 in the upper layer of medicine feeding structure 2, so that the medicine feeding process can be continuously carried out, the phenomenon that the medicine feeding holes 3 in the upper layer of medicine feeding structure 2 are closed and the medicine feeding holes 3 in the lower layer of medicine feeding structure 2 are not opened is avoided, if the phenomenon occurs, because the medicine fills the closed area between the piston 15 and the inner tube 1, and the medicine feeding holes 3 between the inner tube 1 and the piston 15 are not opened, at the moment, the medicine has no release space, under the action of the medicine pressure, the piston 15 can not slide no matter how much force is used to push the piston 15, meanwhile, the arrangement is that only the medicine feeding holes 3 in one layer of medicine feeding structure 2 are opened, and the medicine feeding holes 3 in the other layers of medicine feeding structure 2 are in the closed state, therefore, the phenomenon that the medicine still in the inner tube 1 flows out from the medicine feeding holes 3 in the other layers of the medicine feeding structures 2 in the closed area between the inner tube 1 and the piston 15 is avoided, the phenomenon that the medicine which enters the affected part flows back into the inner tube 1 from the medicine feeding holes 3 in the open area between the piston 15 and the inner tube 1 is avoided, the loss of the medicine is reduced, the medicine can fully act on the affected part as much as possible, and meanwhile, the rotation of the second sleeve 7 also plays a role in driving the medicine to diffuse.

When the guiding element enters the upper section second sleeve 7 of the first sleeve 6, the sliding of the guiding element in the second process deviation groove 11 of the second sleeve 7 drives the second sleeve 7 to rotate, the second process straight groove 12 in the rotated second sleeve 7 is correspondingly communicated with the first process deviation groove 8 in the first sleeve 6, the guiding element enters the first process deviation groove 8 in the first sleeve 6 from the second process straight groove 12 in the second sleeve 7, because the guiding element slides in the guide groove 4 and is limited by the guide groove 4, the guiding element drives the first process deviation groove 8 to rotate, the first process deviation groove 8 drives the first sleeve 6 to rotate, the first sleeve 6 drives the first through hole 23 (belonging to the first inner boss 22) on the first sleeve 6 to be separated from the administration hole 3 in the upper layer administration structure 2, so that the administration hole 3 in the upper layer administration structure 2 is blocked by the first inner boss 22, and the first sleeve 6 drives the administration hole 5 on the first sleeve 6 to be communicated with the administration hole 3 in the layer administration structure 2 in alignment, the medicine flows out from the administration hole 3 of the administration structure 2 (i.e. the administration structure 2 corresponding to the first sleeve 6) under the extrusion action of the piston 15 and flows to the affected part, and the rotated first return straight groove 10 and the second return offset groove 13 of the upper second sleeve 7 are aligned and communicated again.

When the medicine is sucked in the inner tube 1, the bottom of the inner tube 1 extends into an external medicine container, so that the piston 15 slides in a return stroke from the bottom of the inner tube 1, the medicine is sucked into a closed area between the piston 15 and the inner tube 1 under the action of pressure difference, the piston 15 drives the guide part to slide in the guide groove 4 in the return stroke, meanwhile, the guide part slides in the first sliding groove and the second sliding groove, the guide part firstly enters the first return straight groove 10, because the path direction of the first return straight groove 10 is parallel to the path direction of the guide groove 4 (the first return straight groove 10 is vertically arranged), when the guide part slides in the first return straight groove 10, the first sleeve 6 does not rotate, so that the medicine feeding hole 3 of the medicine feeding structure 2 corresponding to the first sleeve 6 is in an open state, the medicine is sucked into the inner tube 1, and then the guide part enters the second return inclined groove 13 of the upper second sleeve 7 from the first return straight groove 10, the guide starts to slide in the second sliding groove, and under the action of the lane changing structure, the guide will slide along the path directions of the second return deviation groove 13 and the second return straight groove 14 of the plurality of second sleeves 7, and the sliding of the guide in the plurality of second sliding grooves during the process causes the plurality of second sleeves 7 to rotate at the same angle, so that the relative positions between the plurality of second sleeves 7 during the return are consistent relative to the relative positions during the initial state, and when the guide slides in the second sliding groove of any one second sleeve 7, the movement of the guide is described as follows:

for convenience and simplicity, two adjacent sections of the second sleeve 7 are labeled as a second sleeve 7C and a second sleeve 7D, wherein the second sleeve 7C is placed below the second sleeve 7D, the guiding member first enters the second return deviation groove 13 of the second sleeve 7C, the guiding member drives the second return deviation groove 13 to rotate, the second return deviation groove 13 drives the second sleeve 7C to rotate/reset, because the relative position between the second sleeve 7C and the second sleeve 7D (not reset) of the upper section is consistent with the relative position in the initial state, the second sleeve 7C drives the second communication hole 20 thereon to rotate reversely, the second communication hole 20 is communicated with the corresponding administration hole 3 of the upper layer administration structure 2 and the corresponding administration hole 5 of the second sleeve 7D of the upper section in an aligned manner, the administration hole 3 of the upper layer administration structure 2 is opened, and the administration hole 3 of the upper layer administration structure 2 is located above the piston 15, therefore, air does not enter the closed area between the piston 15 and the inner tube 1, i.e. the opening of the administration hole 3 of the upper administration structure 2 does not affect the extraction of the medicine, and the second return straight groove 14 of the second sleeve 7C is in alignment communication with the second return offset groove 13 of the upper second sleeve 7D, and then the guiding element enters the second return straight groove 14 of the second sleeve 7C from the second return offset groove 13 of the second sleeve 7C, and the extraction of the medicine is continued.
