The medicine feeding device is provided with a medicine feeding box 2 which is provided with an opening towards right and is arranged in the sleeve 1 in a sliding manner, a medicine storage ring 3 which is hollow in the inside is coaxially arranged on the left side of the medicine feeding box 2, a plurality of rows of medicine discharging holes which are uniformly distributed along the circumferential direction of the medicine storage ring 3 are formed in the medicine storage ring 3, an air bag 4 is arranged on the left side of the medicine feeding box 2, the air bag 4 is communicated with the medicine storage ring 3 through a hose 5, a push rod 6 which is positioned on the right of the air bag 4 is arranged on the medicine feeding box 2 in a sliding manner in a coaxial manner, and the medicine feeding box 2 can rotate along with the left and right movement of the push rod 6.

In order to drive the push rod 6 to move left and right, the right side of the sleeve 1 is provided with a shell in the left-right direction, the right end of the push rod 6 is inserted into the shell and is provided with a wedge plate 7, a guide groove 8 which is communicated front and back and is high left and low right is formed in the wedge plate 7, a through groove which is communicated left and right and is vertically formed in the upper side wall of the shell, an inverted L-shaped pressing rod 9 is hinged to the right side in the through groove through a rotating shaft, and an inserting column 10 which is inserted into the guide groove 8 is arranged on the lower side of the pressing rod 9.

In order to facilitate the reset of the push rod 9 and the push rod 6, a torsion spring is coaxially arranged on the rotating shaft, one end of the torsion spring is fixedly connected with the shell, and the other end of the torsion spring is fixedly connected with the push rod 9.

In order to make the medicine feeding cylinder 2 rotate along with the left and right movement of the push rod 6, the push rod 6 is provided with a spiral groove 11, the right side of the medicine feeding cylinder 2 is in ball joint with a ball 12, and the ball 12 is in sliding connection with the spiral groove 11.

In order to slidingly connect the medicine feeding cylinder 2 with the sleeve 1 and position the medicine feeding cylinder 2, a collar 13 is coaxially arranged on the right side of the medicine feeding cylinder 2, the inner diameter of the left side of the sleeve 1 is larger than the inner diameter of the medicine feeding cylinder 2 and smaller than the inner diameter of the collar 13, and the friction force between the collar 13 and the sleeve 1 is smaller than the friction force between the ball 12 and the spiral groove 11.

In order to facilitate the resetting of the air bag 4 and the ejection of the medicine in the medicine storage ring 3, a left axial spring and a right axial spring are arranged in the air bag 4, an air inlet hole 14 is formed in the right side of the air bag 4, a one-way valve with an opening facing the air bag 4 is arranged in the air inlet hole 14, a one-way valve with an opening facing the medicine storage ring 3 is arranged in the hose 5, and a valve 15 is arranged in the medicine outlet hole.

When the medicine storing ring is used, firstly, medicine liquid or ointment is added into the medicine storing ring 3 through the valve 15 in the medicine outlet hole, the cavity of the medicine storing ring 3 is filled, the shell is held by one hand, the lantern ring 13 is inserted into the vagina of a patient, when the lantern ring 13 moves to a proper position depth, the pressing rod 9 is pressed downwards, the pressing rod 9 drives the inserting column 10 to move downwards, the inserting column 10 slides downwards in the guide groove 8, the wedge-shaped plate 7 moves leftwards, the wedge-shaped plate 7 drives the push rod 6 to move leftwards, because the friction force between the lantern ring 13 and the sleeve 1 is smaller than the friction force between the ball 12 and the spiral groove 11, the relative position between the push rod 6 and the medicine feeding cylinder 2 is not changed, the push rod 6 drives the medicine feeding cylinder 2 to move leftwards to extend out of the sleeve 1, when the lantern ring 13 contacts with the left side wall of the sleeve 1, the medicine storing ring 3 is exposed, and the medicine storing ring 3 contacts with the cervix of the patient;

the push rod 9 is continuously pressed to enable the plunger 10 to slide in the guide groove 8, the push rod 6 is continuously moved leftwards, the medicine feeding cylinder 2 cannot move leftwards because the sleeve ring 13 is in contact with the left side wall of the sleeve 1, the ball 12 slides in the spiral groove 11, the medicine feeding cylinder 2 rotates anticlockwise, meanwhile, the push rod 6 moves leftwards to squeeze the spring, because the one-way valve opening in the air inlet hole 14 faces the air bag 4, air in the air bag 4 flows into the medicine storage ring 3 through the hose 5, the air pressure in the medicine storage ring 3 is increased, the valve 15 is opened, medicine is smeared on a cervical for one circle under the action of the air pressure through the medicine outlet hole, and because the medicine feeding cylinder 2 rotates simultaneously, the medicine feeding cylinder 2 drives the medicine storage ring 3 to rotate, and the medicine is smeared uniformly;

when the smearing is finished, the pressing rod 9 is loosened, under the action force of the torsion spring, the pressing rod 9 swings upwards around the rotating shaft, the pressing rod 9 drives the inserting column 10 to slide upwards in the guide groove 8, the wedge-shaped plate 7 moves rightwards to reset, the wedge-shaped plate 7 drives the push rod 6 to move rightwards, the push rod 6 drives the medicine feeding cylinder 2 to enter the sleeve 1 first, when the medicine feeding cylinder 2 completely enters the sleeve 1, the push rod 6 continues to move rightwards, the medicine feeding cylinder 2 rotates clockwise, meanwhile, under the action force of the spring, the space in the air bag 4 is enlarged, air is sucked through the air inlet hole 14, the air bag 4 is restored to an initial state, and when the medicine feeding cylinder 2 needs to be cleaned or medicines are added into the medicine storage ring 3, the pressing rod 9 is pressed downwards, so that the medicine feeding cylinder 2 extends out of the sleeve 1.

Compared with the prior art, the utility model has the advantages that:

1. the utility model has simple structure, convenient operation, novel conception and strong practicability, and the medicine feeding cylinder, the sleeve and the push rod are arranged, so that the medicine is prevented from being scattered in the vagina to stimulate normal tissues before reaching the focus position, and the waste of the medicine is reduced;

2. the valve, the ball and the spiral groove are arranged, the ball slides in the spiral groove through the driving of the push rod, and meanwhile, the air bag is pressurized, so that the medicine feeding cylinder rotates and sprays out the medicine, and the uniform smearing of all focus positions in the cervix can be completed.
