When the isolating ring 38 is pierced by the U-bar 33 or the piercing block 51, the gas in the thick portion 36 of the rubber sleeve 34 is automatically squeezed into the thin portion 35 of the rubber sleeve 34 with a smaller elasticity coefficient by the thick portion 36 of the rubber sleeve 34 with a larger elasticity coefficient, so that the thin portion 35 of the rubber sleeve 34 is inflated and the transverse dimension is increased to reduce the transverse dimension of the thick portion 36 of the rubber sleeve 34, thereby facilitating the separation of the rubber sleeve 34 from the vagina.
As shown in fig. 1 and 3, a sliding block 19 matched with the plug 3 axially slides in the slot 11; as shown in fig. 1, 2 and 8, a reference pin 21, a positive pin 22 and a negative pin 23 mounted on the sliding block 19 are respectively matched with a reference plug bush 5, a positive plug bush 24 and a negative plug bush 25 on the plug 3; as shown in fig. 3, 8 and 12, reference pin 21, positive pin 22 and negative pin 23 are electrically connected to three sets of electrode pads 37 uniformly distributed in the circumferential direction on the side wall of rubber sleeve 34; a spring A28 for resetting the slide block 19 is arranged in the slot 11; the U-bar 33 axially sliding in the insert rod 7 is driven by the sliding block 19 for several times in one way to gradually approach and finally pierce the isolating ring 38, so that the thick part 36 of the rubber sleeve 34 can not be in good contact with the inner wall of the pelvic floor due to the internal gas leakage after reaching the specified use times.
As shown in fig. 3, 5 and 6, the plunger 7 and the rubber boot 34 are provided with a structure for increasing the probability of the spacer ring 38 being pierced when the rubber boot 34 exceeds the insertion mechanism 6 by a predetermined number of uses.

As shown in fig. 3 and 7, the insertion rod 7 has a cylindrical rod 10 at one end, and the cylindrical rod 10 is located in the thick portion 36 of the rubber sleeve 34; as shown in fig. 5, 6 and 7, a top rod B40 is axially slid in a circular groove B16 on the end surface of the cylindrical rod 10, and a spring B41 for resetting the top rod B40 is installed in a circular groove C17 on the inner wall of the circular groove B16; as shown in fig. 6 and 10, the spherical supporting plate 39 fixedly connected with the inner wall of the rubber sleeve 34 is installed at the tail end of the ejector rod B40; as shown in fig. 5, 6 and 9, a ring sleeve A44 is nested and axially and slidably matched on the top rod; one end of the ring sleeve A44 is provided with three piercing blocks 51 for axially piercing the isolating ring 38 through a ring plate 50, and the inner wall of the ring groove D46 at the other end of the ring sleeve A44 is provided with two groups of inclined elastic clamping plates F48 which are uniformly and densely distributed in the axial direction; the spherical supporting rod is provided with a ring sleeve B52 matched with the ring groove D46; two groups of inclined elastic clamping plates H53 which are uniformly and densely distributed in the axial direction are arranged on the outer side wall of the ring sleeve B52; snap-plate H53 cooperates with snap-plate F48 to cause the puncturing block 51 on ring B52 to be driven in one direction on ring a44 toward spacer ring 38 during insertion of rubber sheath 34 into the vagina without blocking repositioning of ring B52.
Two groups of inclined elastic clamping plates G49 which are uniformly and densely distributed in the axial direction are arranged in a ring groove E47 on the inner wall of the ring sleeve A44; the two groups of clamping plates G49 are respectively matched with the two groups of inclined elastic clamping plates B18 which are uniformly and densely distributed in the axial direction on the cylindrical rod 10, so that the movement of the ring sleeve A44 close to the isolating ring 38 in the axial direction is not hindered, and the ring sleeve A44 is prevented from being far away from the isolating ring 38 in the axial direction.
As shown in fig. 3, 7 and 8, two guide blocks 20 are symmetrically installed on the side wall of the slider 19, and the two guide blocks 20 respectively slide in the two guide grooves 12 on the inner wall of the slot 11; one end of the spring A28 is connected with the end face of the slide block 19, and the other end is connected with the inner end wall of the slot 11. As shown in fig. 5, the spring B41 is nested on the top bar B40; one end of the spring B41 is connected with the end wall of the ring groove C17, and the other end is connected with a compression spring ring 42 arranged on the ejector rod B40;

The working process of the invention is as follows: in the initial state, the plug 3 is separated from the insertion mechanism 6. Spring A28 and spring B41 are both in a compressed state. The two ends of the U-bar 33 are farthest from the isolating ring 38, and the piercing block 51 is farthest from the isolating ring 38. Two groups of clamping plates C27 on the ejector rod A26 are completely meshed with a corresponding group of clamping plates D30 in the driving sleeve 29 respectively, and two clamping plates E31 outside the driving sleeve 29 are meshed with a corresponding group of clamping plates A14 in the square groove 13 respectively. Two groups of snap-gauge B18 on the cylindrical rod 10 are respectively meshed with a corresponding group of snap-gauge G49 in the ring groove E47, and two groups of snap-gauge H53 on the ring sleeve B52 are respectively meshed with a corresponding group of snap-gauge F48 in the ring groove D46. The thick portion 36 of the rubber boot 34 is inflated to a normal state.
When the invention is used for rehabilitation treatment of the muscular nerve of the female pelvic floor, the insertion mechanism 6 is fully inserted on the plug 3, and the insertion flow is as follows:
the end of the slot 11 of the inserted link 7 is inserted into the plug 3 in a nested manner, so that the inserted link 7 is inserted into the plug 3 in a nested manner. When the inserted rod 7 is fully inserted on the plug 3, the reference pin 21, the positive pin 22 and the negative pin 23 in the slot 11 of the inserted rod 7 are fully inserted into the reference plug sleeve 5, the positive plug sleeve 24 and the negative plug sleeve 25 in the circular groove A4 on the end face of the plug 3 respectively. The insertion of the plug-in means 6 into the plug 3 is now complete.
When the plug 3 meets the sliding block 19 in the process of inserting the plug 3 into the slot 11 on the end face of the inserted link 7, the plug 3 which continues to go deep into the slot 11 drives the sliding block 19 to move synchronously into the slot 11, and the spring a28 is further compressed. The slide block 19 drives the driving sleeve 29 to axially move towards the direction close to the isolating ring 38 through a clamping plate C27 on the ejector rod A26 and a clamping plate D30 in the driving sleeve 29, and the driving sleeve 29 drives two branches of the U-shaped rod 33 to synchronously close to the isolating ring 38 through the push rod 32.
Meanwhile, the catch plate E31 on the outer side of the driving sleeve 29 interacts with the catch plate a14 in the square groove 13 in the oblique direction of the two, and the interacting catch plate a14 and catch plate E31 are elastically deformed in the oblique direction and do not hinder the movement of the driving sleeve 29 close to the isolating ring 38.
When the plug 3 is completely inserted into the slot 11 of the plug rod 7, the movement of the sliding block 19 reaches the limit, and the sliding block 19 drives the U rod 33 to complete the displacement of a specified amplitude close to the isolating ring 38 through the driving sleeve 29 and the push rod 32.
After the plug 3 and the plug rod 7 are inserted, the thick part 36 of the rubber sleeve 34 on the insertion mechanism 6 is inserted into the vagina, and in the process that the thick part 36 of the rubber sleeve 34 is inserted into the vagina, the thick part 36 of the rubber sleeve 34 is deformed and extruded to a small extent under the action of a human body, so that the tail end of the thick part 36 of the rubber sleeve 34 drives the ring sleeve B52 and the ejector rod B40 to synchronously move axially along the direction close to the isolating ring 38 through the spherical supporting plate 39, and the spring B41 is further compressed. The ring sleeve B52 drives the ring sleeve A44 to axially slide for a specified amplitude displacement along the direction close to the isolating ring 38 relative to the cylindrical rod 10 through the snap plate H53 and the snap plate F48 in the ring groove D46, and the ring sleeve drives the three puncturing blocks 51 to axially slide for a specified amplitude displacement along the direction close to the isolating ring 38 through the ring plate 50. In the process, the snap plate G49 in the ring groove E47 on the ring sleeve A44 and the snap plate B18 on the cylindrical rod 10 are elastically deformed in the inclining direction due to the mutual pressing of the inclining directions of the two, and the elastic deformation of the snap plate G49 and the snap plate B18 under the interaction does not form an obstruction to the movement of the ring sleeve A44 close to the isolating ring 38.
After the thick part 36 of the rubber sleeve 34 is completely inserted into the vagina, the tail end of the thick part 36 of the rubber sleeve 34 is pressed by a human body, the push rod B40 drives the ring sleeve B52 and the thick part 36 of the rubber sleeve 34 to synchronously reset and restore relative to the cylindrical rod 10 through the spherical supporting plate 39 under the resetting action of the spring B41, the clamping plate F48 in the clamping plate H53 and the ring groove D46 on the ring sleeve B52 are subjected to lodging elastic deformation under the mutual action of the oblique directions of the ring sleeve B53 and the ring groove D46, so that the ring sleeve B52 is not blocked from resetting, the ring sleeve A44 is not driven to reset, the position of the ring sleeve A44 after the displacement close to the isolating ring 38 by a specified amplitude is kept unchanged under the mutual action of the clamping plate B18 and the clamping plate G49, and the clamping plate H53 is still in meshed fit with the clamping plate F48.
After the thick part 36 of the rubber sleeve 34 is completely inserted into the vagina, the three groups of electrode plates 37 on the thick part 36 of the rubber sleeve 34 can effectively form good contact with the inner wall of the vagina due to the larger transverse size of the thick part 36 of the rubber sleeve, so that the invention can ensure the effective electrical stimulation on the pelvic floor muscles in the vagina.
After the treatment of the pelvic floor muscles is finished, the rubber sleeve 34 is pulled out of the vagina, and after the rubber sleeve 34 is completely pulled out of the vagina, the plug 3 is pulled out of the slot 11 of the insertion rod 7, so that the insertion mechanism 6 and the plug 3 can be separated.
In the process of pulling the plug 3 out of the slot 11, the slider 19 drives the ejector rod a26 to gradually reset under the resetting action of the spring a28, the snap-gauge C27 on the ejector rod a26 and the snap-gauge D30 in the driving sleeve 29 are subjected to toppling elastic deformation under the interaction of the two due to the inclined directions of the two, so that the reset of the ejector rod a26 is not hindered, and the driving sleeve 29 is not driven to reset at the same time, so that the position of the U rod 33 after being close to the spacing ring 38 for specified amplitude displacement is kept unchanged under the interaction of the snap-gauge a14 and the snap-gauge E31, and the snap-gauge C27 on the ejector rod a26 is still in meshed fit with the partial snap-gauge D30 in the driving sleeve 29.
The used insertion mechanism 6, which is also within the prescribed number of uses, is sterilized before the next use to prevent bacterial infection. When the used and sterilized insertion mechanism 6 is used again to perform the electrical stimulation treatment on the pelvic floor muscles, the insertion of the insertion mechanism 6 and the plug 3 and the insertion process of the insertion mechanism 6 into the vagina are as described above, and will not be described again.
After the plug 3 is plugged into the slot 11 of the plug rod 7 again, the plug 3 drives the two legs of the U-rod 33 to move by the same prescribed amplitude as before through the slider 19, the ejector pin a26, the clamping plate C27, the clamping plate D30, the driving sleeve 29 and the push rod 32 and further approach the isolating ring 38.
When the insertion mechanism 6 is inserted into the vagina again, the end of the thick part 36 of the rubber sleeve 34 is pressed by the human body to drive the ring sleeve B52 and the ejector rod B40 to move by the same prescribed amplitude displacement as before and further approach the isolating ring 38 through the spherical supporting plate 39, and the ring sleeve A44 drives the three puncturing blocks 51 to move by the same prescribed amplitude displacement as before and further approach the isolating ring 38 through the ring plate 50.
When the use times of the insertion mechanism 6 are accumulated to reach the specified use times, in the process of inserting and matching the insertion mechanism with the plug 3, the plug 3 drives the U rod 33 to puncture the isolating ring 38 through a series of transmission, gas in the thick part 36 of the rubber sleeve 34 can rapidly enter the thin part 35 of the rubber sleeve 34 with a smaller elasticity coefficient through the punctured isolating ring 38 under the extrusion of the thick part 36 of the rubber sleeve 34 with a larger elasticity coefficient, so that the thin part 35 of the rubber sleeve 34 is rapidly swelled, and a user is reminded that the use times of the insertion mechanism 6 reach the limit of the specified use times and can not be used any more, the insertion mechanism 6 needs to be replaced with a new insertion mechanism 6, and the vaginal bacterial infection caused by incomplete disinfection after the insertion mechanism 6 exceeds the specified use times is prevented.
If the isolating ring 38 is not punctured by two branches of the U-bar 33 due to internal structural failure during the insertion of the insertion mechanism 6 into the plug 3 when the usage times of the insertion mechanism 6 are accumulated to reach the specified usage times, the thick portion 36 of the rubber sleeve 34 will drive the three puncturing blocks 51 to puncture the isolating ring 38 through a series of transmission under the squeezing of the human body during the insertion of the insertion mechanism 6 fully inserted into the plug 3 into the vagina, so that the transverse dimension of the thick portion 36 of the rubber sleeve 34 is rapidly reduced. The air in the thick part 36 of the rubber sleeve 34 enters the thin part 35 of the rubber sleeve 34 through the punctured isolating ring 38, and the thin part 35 of the rubber sleeve 34 is rapidly bulged to facilitate the rapid pulling of the rubber sleeve 34 out of the vagina. Under the condition that the transverse size of the thick part 36 of the rubber sleeve 34 is reduced, even if the thick part 36 of the rubber sleeve 34 is inserted into a vagina, the three groups of electrode plates 37 on the thick part 36 of the rubber sleeve 34 can not be in good contact with the inner wall of the vagina due to the reduction of the transverse size of the thick part 36 of the rubber sleeve 34, so that the pelvic floor muscle electrical stimulation device can not normally generate electrical stimulation to the pelvic floor muscle any more, the insertion mechanism 6 is reminded of reaching the limit use times to be self-destroyed, the insertion mechanism 6 needs to be replaced with a new insertion mechanism 6, and the vaginal bacterial infection caused by incomplete disinfection after the insertion mechanism 6 exceeds the specified use times is prevented.
The self-destruction of the insertion mechanism 6 after reaching its limit number of uses ensures that the insertion mechanism 6 is fully utilized to reduce use costs while avoiding bacterial infection to the user of the insertion mechanism 6 due to its repeated use over an extended period of time.
In conclusion, the beneficial effects of the invention are as follows: the insertion mechanism 6 is self-destructed and destroyed after being inserted into the plug 3 for a certain number of times, the use cost of the insertion mechanism 6 is reduced by fully utilizing the insertion mechanism 6, the insertion mechanism 6 is ensured to be replaced after being used for a certain number of times so as to ensure the sanitary requirement, the bacterial infection caused by incomplete disinfection in the long-term repeated use process of the insertion mechanism 6 is avoided, the cost is reduced by fully utilizing the insertion mechanism 6, and the sanitary requirement is met.
In conclusion, the beneficial effects of the invention are as follows: the U-bar 33 and the three puncturing blocks 51 arranged at one end of the ring sleeve A44 of the invention approach further after the plug 3 is completely inserted into the slot 11 on the insertion rod 7 each time and finally puncture the isolating ring 38 when the number of use times exceeds the specified number of times, the gas in the thick part 36 of the rubber sleeve 34 enters the thin part 35 of the rubber sleeve 34 with smaller elasticity coefficient under the extrusion of the thick part 36 of the rubber sleeve 34 with larger elasticity coefficient, so that the three groups of electrode plates 37 on the thick part 36 of the rubber sleeve 34 are not in good contact with the inner wall of the vagina any more, the electrical stimulation of the invention to the muscles in the pelvic floor is invalid, the number of use times of the insertion mechanism 6 reaches the upper limit, the insertion mechanism 6 which is used repeatedly is replaced with a new insertion mechanism 6 in time, and the bacterial infection of the vagina formed by the insertion mechanism 6 which is used repeatedly is avoided. The use cost of the insertion mechanism 6 is reduced by using the insertion mechanism for the specified times, meanwhile, the invention is ensured not to cause bacterial infection in the vagina due to repeated and unlimited use of the insertion mechanism 6, the cost is reduced, and simultaneously, the sanitation and the safety are ensured.
