Further, the eccentric wheel 11 is a flexible rubber wheel, and can be intermittently in friction contact with the medicine feeding barrel 4 under the driving of the motor 10, so that the movement of the medicine feeding barrel 4 can be conveniently adjusted, and the adjustment of the rotation angle of the medicine feeding barrel 4 can be realized.

Further, the balloon 13 is a rubber inflatable balloon on a conventional sphygmomanometer, which is a prior art and is not described herein again.

Further optimizing scheme, seal assembly includes plug screw 16 and installation stopper 17, plug screw 16 and the spiro union of 4 inner chamber lateral walls bottom of medicine feed barrel, plug screw 16 top surface rigid coupling has installation stopper 17, installation stopper 17 can dismantle with the bag bottom and be connected, plug screw 16 and installation stopper 17 set up the air vent 18 that is linked together respectively, installation stopper 17 passes through air vent 18 and equipment unit rigid coupling and intercommunication, the closure of medicine feed barrel 4 has been realized to plug screw 16 bottom surface, air vent 18 passes through trachea (not shown in the drawing) and air pump 19 rigid coupling and intercommunication simultaneously, the trachea runs through the bottom surface of slide cartridge 6 and with slide cartridge 6 sealing fixed connection, the gas leakage in airtight space has been avoided.

According to a further optimized scheme, the equipment set comprises an air pump 19 and a peristaltic pump 20, wherein the air pump 19 is fixedly connected and communicated with the vent hole 18 through a connecting pipe (not shown in the drawing), and the peristaltic pump 20 is fixedly connected and communicated with the flow channel 5 through a feeding pipe.

Further, the peristaltic pump 20 is in communication with an external medicine supply box or bottle (both shown), and can feed the ointment from the external medicine supply box or bottle into the flow path and spray the ointment onto the pouch 3 between the top 2 and the top of the medicine feed cylinder 4.

Furthermore, the length of the connecting pipe can meet the requirement of the movement of the medicine feeding barrel 4, and meanwhile, the connecting pipe penetrates through the bottom surface of the sliding barrel 6 and is fixedly connected with the sliding barrel 6 in a sealing mode, so that air leakage of a closed space is avoided.

Further optimize the scheme, in order to facilitate sending medicine cartridge 4 can get into women's vagina smoothly, send the diameter of medicine cartridge 4 to be less than the diameter of introitus, and send medicine cartridge 4 to be curved structure, its shape satisfies the physiological curvature of women's vagina, send the arbitrary perpendicular to of medicine cartridge 4 to send the cross section of medicine cartridge axis to be the same circular, can be convenient for send the slip of medicine cartridge 4 and fixing base 1, avoid leading to sending medicine cartridge 4 when flexible removal because the change of the diameter of sending medicine cartridge 4, take place to rock and cause the discomfort to the human body.

Furthermore, the fixing seat 1 and the medicine feeding barrel 4 are connected in a sliding mode through rubber plugs embedded in the fixing seat 1, and clamping stagnation of the medicine feeding barrel 4 in the moving process is avoided.

Further optimizing the scheme, bag top 2 and bag 3 are medical rubber material, can enough avoid dosing the bag and cause adverse effect to the human body, also can utilize the elasticity of rubber and can expand, realize paining smoothly of ointment.

The working process of the embodiment is as follows:

will send cartridge 4 to utilize sacculus 13 extrusion, improve the pressure in airtight space, promote to send cartridge 4 and sealing ring 8 to move upwards, and then promote to send cartridge 4 to get into women's vagina in, according to patient's self impression, if find uncomfortable, then through the rotatory eccentric wheel 11 of starter motor 10, the lateral surface of cartridge 4 is sent in the periodic friction of eccentric wheel 11, realizes sending the rotation of cartridge 4, link patient's discomfort. After the patient feels the focus, determines the depth of the entering and sends the medicine feeding barrel 4 to the right position, because the length of the bag 3 is longer than that of the medicine feeding barrel 4, at this time, the air pump 19 is inflated to push the bag top 2 plugged into the top end of the inner cavity of the medicine feeding barrel 4 out of the medicine feeding barrel 4, the bag in the inner cavity of the medicine feeding barrel 4 is inflated continuously to be full, the peristaltic pump 20 is started, the peristaltic pump 20 feeds the ointment into the flow channel 5 and finally sprays the ointment onto the bag 3 between the bag top 2 and the top surface of the medicine feeding barrel 4, and then the bag 3 is inflated, because the thickness of the bag top 2 is thicker, the bag top 2 can not expand due to the inflation of the bag 3, at the moment, the bag 3 between the bag top 2 and the top surface of the medicine feeding barrel 4 can expand, the ointment is smeared on the focus along with the expansion of the bag 3, the bag 3 is an air bag, so that smearing force can be applied softly, and the comfort level of a patient and the smearing accuracy are improved.

After the painting is finished, the air tap 15 is pressed to release the air pressure in the closed space, the medicine feeding barrel 4 automatically retracts under the action of gravity, and in the process, the eccentric wheel 11 is not in contact with the side face of the medicine feeding barrel 4, so that the medicine feeding barrel 4 can retract conveniently.
