The transformer 36 of the present invention is a conventional transformer, and the transformer 36 can convert the external 220V voltage into a voltage suitable for charging the battery 39.

The working process of the invention is as follows: in the initial state, the insertion mechanism 1 is separated from the grip mechanism 31. The trigger rod 81 in the handle mechanism 31 has a slope B82 protruding from the side of the cylindrical plug 50. Spring A22, spring B74, and spring C83 are all in compression, and spring D89 is in tension. The exposed ends of the three racks B73 on the sliding column 64 are opposite to the annular clamping groove A46 on the ring sleeve B45 and are not inserted into the clamping groove A46, the circuit board B41 abuts against the end of the circular groove C51 of the cylindrical socket 49, the ring sleeve B45 abuts against the circuit board B41, and all the circular blocks 48 are respectively positioned in the contact bending positions of the corresponding copper contact pieces 43 and have a certain distance with the inner wall of the concave cambered surface of the contact bending positions of the copper contact pieces 43. The end of the shift lever 76 is exposed in the movable slot B59, the end of the barbed rod 92 close to the end face of the cylindrical plug 50 is swung out of the corresponding receiving slot 91 by a certain angle around the corresponding fixed shaft 94, the volute spring 95 is in a pre-compressed state, and the barbed rod 92 abuts against the corresponding swing limiting block 96.

In the initial state, the air leakage groove C29 on the ring sleeve A28 is communicated with the air leakage groove B20 on the air bag rod 16, the sliding rod A21 closes the air leakage groove A11 on the inner wall of the sliding groove A10, and the pull rope 24 is in a stretched straight state.

When the invention is needed to be used for rehabilitation treatment of the muscular nerve of the female pelvic floor, the insertion mechanism 1 is firstly inserted on the handle mechanism 31, and the insertion flow is as follows:

when the positioning plane a6 in the positioning slot 3 on the plug bush 2 of the insertion mechanism 1 is opposite to the positioning plane B61 on the cylindrical plug 50 of the grip mechanism 31, the end of the positioning slot 3 of the plug bush 2 is inserted into the cylindrical plug 50 of the grip mechanism 31 in a nested manner, so that the positioning insertion nesting of the plug bush 2 to the cylindrical plug 50 is realized, and the end of the positioning slot 3 of the plug bush 2 is inserted into the circular groove F60 on the cylindrical socket 49. When the plug bush 2 is completely inserted into the cylindrical socket 49, the end of the positioning slot 3 of the plug bush 2 is completely inserted into the annular area between the cylindrical plug 50 and the inner wall of the circular groove F60, and the reference electrode 12, the positive electrode 14 and the negative electrode 15 on the plug bush 2 are respectively in mutual abutting contact with the corresponding correct contact points of the copper contact sheet 43.

During the insertion of the insertion mechanism 1 into the handle mechanism 31, the end of the positioning slot 3 of the insertion sleeve 2 interacts with the inclined surface B82 on the trigger rod 81, so that the trigger rod 81 is quickly and completely retracted into the sliding groove B54 on the cylindrical plug 50, and the spring C83 is further compressed. The trigger rod 81 drives the telescopic shaft 70 to rotate through the rack A80 and the gear A79, and the telescopic shaft 70 drives the exposed ends of the three racks B73 to rapidly move into the annular clamping groove A46 on the ring sleeve B45 through the gear B72.

With the plug bush 2 being continuously plugged onto the cylindrical plug 50, before the reference electrode 12, the positive electrode 14 and the negative electrode 15 on the plug bush 2 meet the copper contact piece 43, the end of the positioning slot 3 of the plug bush 2 interacts with the shift lever 76, the shift lever 76 is quickly swung into the movable slot B59 on the cylindrical socket 49 under the action of the plug bush 2, the shift lever 76 drives the ring sleeve B45 to quickly move along the central axis direction of the cylindrical socket 49 towards the direction of the insertion mechanism 1 through the round pin 78, the sliding rod B75, the sliding column 64, the inner shaft of the telescopic shaft 70 which is rotatably matched with the sliding column 64, the gear B72 and the rack B73 of which the three exposed ends are inserted into the slots a46, and the telescopic shaft 70 is contracted for a certain length. The spring B74 is further compressed, and the ring sleeve B45 drives all the round blocks 48 to respectively press the inner wall of the concave arc surface at the contact bending position of the corresponding copper contact piece 43 through the ejector rod, so that the bending end of the copper contact piece 43 swings towards the direction close to the side wall of the cylindrical plug 50 under the pressing of the corresponding round block 48, and finally the bending angle of the copper contact piece 43 is increased, thereby ensuring that the reference electrode 12, the positive electrode 14 and the negative electrode 15 on the plug bush 2 are respectively in good contact with the corresponding copper contact piece 43.

When the end of the positioning slot 3 of the plug bush 2 is about to meet the copper contact 43, the tail end of the shift lever 76 completely enters the range of the movable groove A4 on the inner wall of the positioning slot 3 of the plug bush 2, the sliding column 64 is quickly reset under the reset action of the spring B74, the sliding column 64 drives the shift lever 76 to swing back and reset through the sliding rod B75, meanwhile, the sliding column 64 drives the three racks B73 to reset along the axis of the central axis of the cylindrical socket 49 through the inner shaft of the telescopic shaft 70 and the gear B72, the telescopic shaft 70 extends to the length of the initial state, and the exposed ends of the three racks B73 on the side wall of the sliding column 64 are still inserted in the range of the clamping groove A46 on the ring sleeve B45.

With the continuous insertion of the plug bush 2 onto the cylindrical plug 50, the reference electrode 12, the positive electrode 14 and the negative electrode 15 at the end of the positioning slot 3 of the plug bush 2 meet the corresponding copper contact sheet 43 and are in abutting contact with each other, the free end of the contact bending part of the copper contact sheet 43 swings in the direction away from the side wall of the cylindrical plug 50 under the abutting pressure of the plug bush 2, the free end of the contact bending part of the copper contact sheet 43 abuts against the round block 48 to move towards the initial position, and the round block 48 drives the ring sleeve B45 to move towards the direction close to the circuit board B41 through the ejector rod. When the plug bush 2 is completely plugged on the cylindrical plug 50, the reference electrode 12, the positive electrode 14 and the negative electrode 15 at the end of the positioning slot 3 of the plug bush 2 are respectively in abutting contact with the corresponding copper contact piece 43. At this point, the insertion of the insertion mechanism 1 into the grip mechanism 31 is completed.

At this time, if the indicator lamps 13 on the reference electrode 12, the positive electrode 14 and the negative electrode 15 display green, it indicates that the electric signals generated by the reference electrode 12, the positive electrode 14 and the negative electrode 15 are normal. If the indicator lights 13 on the reference electrode 12, the positive electrode 14 and the negative electrode 15 show red color, it indicates that the electrical signals generated by the reference electrode 12, the positive electrode 14 and the negative electrode 15 are abnormal. When the electrical signals generated by the reference electrode 12, the positive electrode 14 and the negative electrode 15 are abnormal, the position of the insertion mechanism 1 in the vagina needs to be readjusted, so that the pelvic floor muscle rehabilitation therapy can be continuously used.

In the process that the insertion mechanism 1 is inserted into the grip mechanism 31, the conical tip of the ejector rod B90 in the middle of the end face of the cylindrical plug 50 can pierce through the rubber film in the plug bush 2 and press the traction block 25, and the traction block 25 drives the sliding rod A21 to slide along the radial direction of the circular groove B8 in the plug bush 2 through the pull rope 24 and gradually open the air leakage groove A11 on the inner wall of the sliding groove A10.

In the process that all barb rods 92 on the ejector rod B90 pass through the rubber film along with the ejector rod, barb rods 92 are pressed into corresponding accommodating grooves 91 by the piercing holes formed in the rubber film, a volute spring 95 resetting barb rods 92 is further compressed, the barb rods 92 entering the accommodating grooves 91 do not form further expansion on the piercing holes pierced in the rubber film, the piercing holes in the rubber film form effective coating seal on the outer side wall of the ejector rod B90, and gas in the air bag rod 16 is prevented from leaking through the piercing holes pierced by the ejector rod B90 on the rubber film. After the barbed rod 92 passes through the perforation of the rubber film, the barbed rod 92 is instantaneously returned to its original position by the return action of the corresponding spiral spring 95.

When the insertion mechanism 1 is inserted into the handle mechanism 31, the sliding rod a21 slides to the limit, the spring a22 is further stretched, the air leakage groove a11 on the side wall of the sliding groove a10 is opened, the air in the air bag rod 16 slowly leaks through the air leakage groove a11, the sliding groove a10, the air leakage groove C29 and the air leakage groove C29 on the inner wall of the ring sleeve a28, and at the moment, the leakage speed of the air in the air bag rod 16 does not cause the air bag rod 16 to generate a fatigue state in the use process of inserting the insertion mechanism 1 into the vagina, and the normal use of the air bag rod 16 is maintained.

When the insertion mechanism 1 is quickly inserted into the grip mechanism 31, the insertion mechanism is inserted into the vagina of a human body for use within a specified time range, so that the phenomenon that the air bag rod 16 is too soft due to too much internal air leakage and the use effect is influenced because the insertion mechanism 1 inserted into the grip mechanism 31 stays outside the human body for too long time is avoided.

When the insertion device 1 is inserted into the vagina, the ring A28 is tightly pressed against the human body, the ring A28 slides to the limit position along the axial direction of the outer side wall of the air bag rod 16 towards the grip mechanism 31 under the pressing action of the human body, the ring A28 drives the ring D87 to slide on the ring C85, and the spring D89 is further compressed. The air leakage groove C29 on the ring sleeve A28 is completely staggered with the air leakage groove B20 on the air bag rod 16, and the sealing sleeve 30 on the inner wall of the ring sleeve A28 closes the air leakage groove B20 on the air bag rod 16, so that the air in the air bag rod 16 is prevented from leaking out in the use process, and the hardness of the air bag rod 16 is ensured.

After the insertion mechanism 1 of the invention is completely inserted into the vagina, the switch button 35 is pressed to start the invention to treat the pelvic floor muscles, the reference electrode 12, the positive electrode 14 and the negative electrode 15 generate electric signals and form effective electric stimulation on the muscles at a certain part of the pelvic floor through the electrode slice 17 on the air sac bar 16.

When the use of the invention is finished, the switch button 35 is pressed again to close the operation of the invention, and the insertion mechanism 1 is pulled out from the vagina.

After the insertion mechanism 1 is pulled out of the vagina, the ring sleeve D87 is reset relative to the ring sleeve C85 under the reset action of the spring D89, the ring sleeve D87 drives the ring sleeve A28 to complete axial reset on the outer side wall of the air bag rod 16, the air leakage groove C29 on the ring sleeve A28 is opposite to the air leakage groove B20 on the air bag rod 16 again, the sealing sleeve 30 on the inner wall of the ring sleeve A28 is opened to the air leakage groove B20 on the air bag rod 16 again, and the air in the air bag rod 16 leaks out through the air leakage groove A11, the sliding groove A10, the air leakage groove B20 and the annular air leakage groove C29 which are still in an opened state. If the user forgets to pull the disposable insertion mechanism 1 away from the grip mechanism 31 after the use of the present invention, the air in the air bag rod 16 will be completely discharged with the passage of time, and eventually the air bag rod 16 will be deflated and soft to show that it can not be used, and the deflated and deflated air bag rod 16 is used, so as to ensure that the used insertion mechanism 1 can not be reused for vaginal insertion, and avoid cross infection of secondary use.

After the operation of the present invention is stopped, the insertion mechanism 1 is pulled out from the vagina, and then the insertion mechanism 1 is pulled out from the handle mechanism 31 for disassembly.

During the process of detaching the insertion mechanism 1 from the grip mechanism 31, the reference electrode 12, the positive electrode 14 and the negative electrode 15 on the plug bush 2 are firstly separated from the corresponding copper contact piece 43, then the tail end of the shift lever 76 interacts with the inclined plane A5 in the movable groove A4 and swings towards the movable groove B59 again under the action of the inclined plane A5, the shift lever 76 drives all the round blocks 48 to respectively press against the inner wall of the concave cambered surface at the contact bending part of the corresponding copper contact piece 43 through a series of transmission, so that the copper contact piece 43 completes deformation and reset at the contact bending part, and the spring B74 is further compressed again. When the plug bush 2 is separated from the shift lever 76, the sliding column 64 drives the shift lever 76 to swing back and reset instantly through a series of transmission under the reset action of the spring B74, and meanwhile, the sliding column 64 drives the three racks B73 to reset axially through a series of transmission.

With the plug bush 2 being separated from the trigger rod 81, the trigger rod 81 is reset under the reset action of the spring C83, and the trigger rod 81 drives the three racks B73 to be completely separated from the clamping grooves a46 of the ring bush B45 through a series of transmission and completes the reset.

In the process of pulling the plug bush 2 away from the cylindrical plug 50, the cylindrical plug 50 drives the ejector rod B90 to break away from the perforation on the rubber film, all barb rods 92 on the ejector rod B90 tear the perforation on the rubber film destructively in the barb mode when passing through the rubber film, ensure that gas in the air bag rod 16 leaks quickly through the destroyed rubber film after the insertion mechanism 1 is pulled away from the grip mechanism 31, make the insertion mechanism 1 form self-destruction after being pulled away from the grip mechanism 31, ensure that the disposable insertion mechanism 1 pulled away from the vagina can not carry out secondary utilization, and prevent cross infection.

When the insertion mechanism 1 is completely pulled out of the grip mechanism 31, the grip mechanism 31 is swung, so that the ring sleeve B45 drives all the round blocks 48 to reset through the ejector rod A47.

When the battery 39 in the handle mechanism 31 is not enough, the battery is charged by connecting the transformer joint 36 with the external 220V power supply, and the transformer joint 36 is disconnected with the external 220V power supply after the charging is finished.

In conclusion, the beneficial effects of the invention are as follows: the insertion mechanism 1 with the self-destruction structure is arranged in the invention, when the insertion mechanism 1 is inserted on the handle mechanism 31 for the first time, the insertion mechanism 1 can be normally used for being inserted into a vaginal cavity, after the insertion mechanism 1 is pulled out of the vaginal cavity, the insertion mechanism 1 can not be used again due to the leakage of the sealing gas in the air bag rod 16, the insertion mechanism 1 is prevented from being used repeatedly after being pulled out of the vagina of a human body, the cross infection is prevented, and positive prevention and control are formed for controlling hospital feeling and preventing the patient from being infected again.

In addition, the copper contact piece 43 of the present invention, which is engaged with the reference electrode 12, the positive electrode 14 and the negative electrode 15 of the socket 2, is not pressed down by the inserted socket 2 in case of deformation of the copper contact piece 43 due to the engagement of the upper clip 44 thereof with the clip groove B53. Meanwhile, in the process of inserting and mounting the plug bush 2 to the cylindrical socket 49, the plug bush 2 drives the round blocks 48 mounted on the ring sleeve B45 to restore the bent parts of the corresponding copper contact pieces 43 through a series of transmissions, so that poor contact between the copper contact pieces 43 and the reference electrode 12, the positive electrode 14 and the negative electrode 15 on the plug bush 2 after the reciprocating long-time matching of the plug bush 2 is avoided, and the use effectiveness of the insertion mechanism 1 in the process of treating the muscular nerves in the vagina is ensured.
