Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a fertility aid device that improves the physiological and psychological state of assisted reproduction. Background Technology

[0002] An assisted reproductive device includes a piston tube, a plunger rod with a piston at the front end, and an outer tube. The front end of the plunger rod extends into the piston tube from the rear end, and the piston abuts against the inner wall of the piston tube. The outer tube is fitted over the outside of the piston tube. A detachable semen collection container is connected to the front end of the piston tube. After the assisted reproductive device is inserted into the vagina, pushing the piston rod can pump semen from the front end of the piston tube to the cervix.

[0003] However, among women with relatively low natural pregnancy rates, many harbor negative feelings or even aversion to sex due to psychological, physiological, or traditional factors. This may lead to resistance to the use of the aforementioned simple yet cumbersome fertility devices. To address this, another type of fertility device has been developed that incorporates a vibration function. The vibration motor is positioned on the device away from the semen container, closer to the tail end. After insertion into the vagina, the device first activates vibration to stimulate the vagina and enhance sexual sensation before pushing the piston rod to pump out the semen.

[0004] However, in reality, users who are resistant to assisted reproductive devices are often more resistant to the beginning of the insertion process. The existing design of this type of vibrating assisted reproductive device does not take into account the user's physiological and psychological state before and during the insertion process. Utility Model Content

[0005] The purpose of this invention is to provide a fertility assisted device that can improve the physiological and psychological state of assisted reproduction before and during implantation.

[0006] The assisted reproductive device provided by this utility model includes a piston and a piston tube that are piston-coupled in a straight line. The front end of the piston tube is provided with a semen storage space and an outlet hole of the semen storage space. It also includes a vibration module and a propulsion module. The propulsion module includes a propulsion component that can move in a straight line. The propulsion component is provided with a first cavity, and the vibration module is placed in the first cavity. The propulsion component can push the piston forward.

[0007] As can be seen from the above solution, this utility model retains the integration of the vibration module into the assisted reproductive device. However, unlike existing vibration-type assisted reproductive devices, the vibration module of this utility model is integrated into the front of the assisted reproductive device near the piston. Because the piston is close to the head of the assisted reproductive device, the vibration is better transmitted to the head. Therefore, the user can experience stimulation from the vibration of the head of the assisted reproductive device before and during insertion, which can alleviate resistance, relax the mind and body, and moisten the vaginal environment, making the insertion of the assisted reproductive device more comfortable and smooth. Once the assisted reproductive device is in place, the user does not need complicated and cumbersome stretching and pushing operations; they only need to press a button to control the advancement module to automatically pump out semen to complete the assisted reproduction. It is evident that this utility model's assisted reproductive device can improve the physiological and psychological state before and during insertion, facilitating a smoother and easier assisted reproduction process.

[0008] A further option is to have the piston mounted outside the propulsion component; or, to include an internal component, with the piston mounted outside the internal component and the propulsion component abutting against the internal component; the internal component is provided with a screw hole for detachable connection with the screw of the pull rod, and the piston tube, piston, and internal component can be disassembled simultaneously, with the screw hole exposed when the piston tube is in the disassembled state.

[0009] As can be seen from the above, in the technical solution where the piston is mounted outside the propulsion component, the vibration of the propulsion component is transmitted more directly to the piston, and then better to the head of the fertility device. The design where the piston module can be detached facilitates manual pumping of semen by the user. The lever can be inserted through the screw thread and rotated to lock it in place. The user can then pull the lever to pump semen from the outlet of the piston tube.

[0010] A further embodiment is that the propulsion component includes a first piece; a first engaging structure assembly is provided between the first piece and the piston, the first engaging structure assembly including a first engaging structure disposed on the outer periphery of the first piece and a second engaging structure disposed on the inner periphery of the piston, one of the first engaging structure and the second engaging structure being a protrusion along the radial direction of the piston, and the other of the first engaging structure and the second engaging structure being a groove along the radial direction, the first engaging structure and the second engaging structure cooperating to fix the relative position of the first piece and the piston in the linear direction.

[0011] As can be seen from the above, since the piston's forward and backward movement is driven by the first component, the first engagement structure group ensures a good engagement relationship between the piston and the first component, especially the relative fixation in the straight direction. This arrangement enables the piston and the first component to maintain a long-term, effective, and stable connection, making the product more durable.

[0012] A further proposed solution is that the outer periphery of the piston is provided with a sealing rib, which abuts against the inner wall of the piston tube; at least one set of engaging structures and the sealing rib are on the same plane perpendicular to the straight line direction.

[0013] As can be seen from the above, this design can use the force generated by the contact between the piston and the piston tube to prevent the first engaging structure and the second engaging structure from separating radially, thereby further ensuring that the piston and the first part maintain a stable engaging relationship.

[0014] Another further design is that the vibration module includes an eccentric rotor; the piston is provided with a second chamber, and the first component and the eccentric rotor are both located in the second chamber.

[0015] As can be seen from the above, with this setting, the eccentric rotor that generates vibration is located inside the piston, and the vibration is further and more effectively transmitted to the head of the assisted reproductive device, achieving a better stimulation effect.

[0016] Another further embodiment is that the propulsion component includes a second part, which is combined with the first part along a straight direction to form a first cavity; the vibration module includes a first drive unit, at least a portion of which is located inside the second part.

[0017] As can be seen above, the second component is assembled first, followed by the installation of the vibration module into the first cavity, and then the first component is closed and secured. This design reduces the assembly difficulty of the propulsion components and the vibration module.

[0018] Another further embodiment includes a third component in the propulsion component; the propulsion module includes a second drive unit, a reciprocating screw, a moving component, and a guide component; the reciprocating screw is arranged in a straight line, and the second drive unit drives the reciprocating screw to rotate; the guide component is fixedly arranged on the outer periphery of the reciprocating screw, and the third component is arranged on the outer periphery of the guide component and slides in cooperation with the guide component; the guide component is provided with a guide hole, which extends in a straight line and connects between the reciprocating screw and the third component, and the guide hole has a first entrance in the straight line; the moving component passes through the guide hole and slides in cooperation with the guide hole in a straight line, one end of the moving component cooperates with the third component, and the other end of the moving component cooperates with the threaded groove of the reciprocating screw.

[0019] As can be seen from the above, with this configuration, the second drive unit only needs to rotate in one direction to drive the piston to complete forward and backward movements, thus reducing the cost of the drive unit.

[0020] A further embodiment includes a propulsion component that also includes a connector; a third component includes a through-hole, and the connector can be detachably installed in the through-hole from the outer periphery of the third component; the third component has a concave first arc portion, and the connector has a concave second arc portion, with the first arc portion and the second annular portion being opposite each other and forming a shaft hole between them; the third component has a second inlet in a straight line direction, and the first arc portion, the second arc portion, and the second inlet are arranged sequentially in a straight line direction; the moving component includes a shaft body that mates with the shaft hole.

[0021] As can be seen from the above, since the guide and the third component both need to be fitted along a straight line and must be fitted one by one from the inside out onto the reciprocating screw, while the moving component extends in a direction perpendicular to the straight line, crossing the reciprocating screw, the guide, and the third component, it presents some obstruction. This arrangement makes the assembly of the propulsion component somewhat difficult. However, this utility model combines a detachable connector with a second inlet on the third component and a first inlet on the guide. Both the first and second inlets are used for the moving component to enter along a straight line. This arrangement allows the guide and the third component to be fitted without obstruction from the moving component. Finally, the connector is installed to restrict the moving component and give it rotational freedom.

[0022] A further embodiment is that the guide member is arranged around the reciprocating lead screw, and the outer peripheral surface of the guide member mates with the inner peripheral surface of the third member; and / or, the inner peripheral surface of the third member is provided with a protrusion, the protrusion protrudes toward the reciprocating lead screw and extends in a straight line, the protrusion mates with the guide hole, and the first arc portion is provided at the extended end of the protrusion.

[0023] As can be seen from the above, this setting can ensure that there is no relative rotation between the guide and the third part, and more importantly, it can ensure that the moving part moves back and forth in a straight line, thus ensuring the stability and effectiveness of the action.

[0024] A further embodiment includes a first housing connected to the piston tube and arranged sequentially along a straight line, with the first housing fitted over the third component; it also includes a detection module and a component to be detected; the component to be detected is disposed on the third component, and the detection module is disposed on the first housing, the detection module including at least two detection units spaced apart along a straight line; when the propulsion member is at a first extreme position in the straight line, the component to be detected is within the detection range of one of the detection units; when the propulsion member is at a second extreme position in the straight line, the component to be detected is within the detection range of the other detection unit.

[0025] As can be seen from the above, under this setting, the propulsion component can be sensed when it moves forward or backward to the corresponding limit position, and the motor of the propulsion module can be controlled to start and stop based on the corresponding sensing signal.

[0038] First embodiment of assisted reproductive device

[0039] See Figure 1 In the diagram, the x-axis represents the straight line direction of this invention, which is also the length direction of the assisted reproductive device and the axial direction of the piston 12 and piston tube 11. Additionally, Figure 1 The front part along the positive x-axis is the head of the assisted reproductive device. Figure 1 The rear part along the positive x-axis is the tail of the assisted reproductive device.

[0040] The assisted reproductive device of this embodiment includes a piston module 1, a vibration module 2, a propulsion module 3, an outer casing assembly, a housing assembly, a battery 95, a circuit board 96, and a button 97.

[0041] The piston module 1 includes a piston 12 and a piston tube 11 that cooperate with each other. The front end of the piston tube 11 is provided with a semen storage space 110 and an ejaculation port 1101 of the semen storage space 110.

[0042] The vibration module 2 includes a first drive unit 21 and an eccentric rotor 22 driven by the first drive unit 21 to rotate. The rotation axis of the eccentric rotor 22 coincides with the axis of the piston 12.

[0043] Among them, the propulsion module 3 mainly adopts a telescopic gearbox, which includes a first drive unit 39, a reciprocating screw 38, a guide 37, a sealing ring 36, a moving part 35, a connecting part 34, and a propulsion component that can reciprocate along the x-axis direction. The propulsion component includes a third part 33, a second part 32, and a first part 31.

[0044] The outer casing assembly includes a head cover 91 and a body cover 92, and the shell assembly includes a first shell 93 and a second shell 94.

[0045] See Figure 1 and Figure 2 The second housing 94 actually comprises two half-shell structures divided into two parts by the base surface of the assisted reproductive device's axis. The second housing 94 includes a cylindrical wall 941 and an end wall 942 located at the tail of the assisted reproductive device. The first housing 93 is cylindrical. The first end of the first housing 93 and the cylindrical wall 941 of the second housing 94 are connected and fixed by a snap-fit. The second end of the first housing 93 is fitted onto the tail of the cylindrical wall of the piston tube 11. The external thread 119 at the tail of the cylindrical wall of the piston tube 11 ( Figure 3 (As shown) The second housing 94, the first housing 93, and the piston tube 11 are connected in sequence along the positive x-axis to form the complete shell of the assisted reproductive device. The piston 12, vibration module 2, propulsion module 3, battery 95, circuit board 96, and button 97 are all set inside the shell as internal structures, while the outer casing is fitted outside the shell.

[0046] See also Figure 1 and Figure 2 The battery 95, circuit board 96, button 97 and first drive unit 39 are all located in the second housing 94. The second housing 94 is also provided with a button hole 940 for the button 97 to pass through. The other structures of the propulsion module 3, except for the first drive unit 39, are mainly located in the first housing 93. The piston 12 is located in the piston tube 11. The first component 31 and the vibration module 2 can move between the first housing 93 and the piston 12.

[0047] See Figure 1 , Figure 3 as well as Figure 7The third piece 3, the second piece 2, and the first piece 1 are sequentially connected and arranged along the positive x-axis. The first piece 1 is fixedly connected to the piston 12. A disc 311 is provided at the front end of the first piece 1. The disc 311 protrudes radially from the piston 12 towards the outer periphery of the disc 311. Correspondingly, in the x-axis direction, a second annular groove 313 is formed on one side of the disc 311. The inner periphery of the second annular groove 313 is configured as a cross-shaped connecting post 3131. Additionally, a first annular groove 312, closer to the second piece 32 than the second annular groove 313, is also provided on the outer periphery of the first piece 1. Furthermore, from the first annular groove 312 to the second annular groove 313, the outer peripheral surface of the first piece 1 is configured as a gradually decreasing convex arc surface along its cross-section. The disc 311, the first annular groove 312, and the second annular groove 313 are all first engaging structures provided on the outer periphery of the first piece 1 in this invention. The disc 311 is a protrusion, while the first annular groove 312 and the second annular groove 313 are both grooves.

[0048] continue Figure 1 , Figure 3 as well as Figure 7 In contrast, the inner periphery of the second chamber 1200 of the piston 12 is provided with a third annular groove 121, a second annular protrusion 123 and a first annular protrusion 122 arranged sequentially along the negative x-axis. The third annular groove 121, the second annular protrusion 123 and the first annular protrusion 122 are all the second engaging structures of this utility model. The third annular groove 121 is a slot, and the second annular protrusion 123 and the first annular protrusion 122 are both protrusions.

[0049] The piston 12 is fitted outside the first piece 31, that is, the first piece 31 is installed in the second cavity 1200. The third annular groove 121 engages with the disc 311, the first annular protrusion 122 engages with the first annular groove 312, and the second annular protrusion 123 engages with the second annular groove 313. The first engagement structure and the second engagement structure constitute the first engagement structure group of this utility model. With the cooperation of multiple groups of first engagement structures, the first engagement structure and the second engagement structure cooperate to fix the relative position of the first piece 31 and the piston in the x-axis direction.

[0050] Furthermore, the outer periphery of the piston 12 is provided with two sealing ribs 129 spaced apart along the x-axis. The sealing ribs 129 abut against the inner wall surface of the piston tube 11. See also Figure 7 The third annular groove 121, the disc 311, and the sealing rib 129 relatively close to the head of the assisted reproductive device are all on the same plane L perpendicular to the x-axis. This arrangement can use the force generated by the contact between the piston and the piston tube 11 to prevent the first engaging structure and the second engaging structure from separating radially, further ensuring that the piston 12 and the first piece 31 maintain a stable engaging relationship.

[0051] See Figure 1 , Figure 4 and Figure 7 The second piece 32 and the first piece 31 are combined along the x-axis to form a first cavity 300. The first drive unit 21 is a motor, and at least a portion of the first drive unit 21 is located inside the second piece 32. The first piece 31 and the eccentric rotor 22 are both located in the second cavity 1200. With this configuration, the second piece 32 can be first glued and fixed to the third piece 33 by screwing screws inside the second piece 32, and then the vibration module 2 can be installed and the first piece 31 can be closed. This configuration optimizes the product assembly structure and reduces assembly difficulty. Furthermore, to ensure the connection stability between the first piece 31 and the second piece 32, in other embodiments, the first piece 31 and the second piece 32 can be connected by threads.

[0052] See Figure 1 , Figure 5 and Figure 6 The second drive unit 39 is a motor. Driven by the second drive unit 39, the reciprocating screw 38 can rotate with the axis of the piston 12 as the rotation center. The moving part 35 functions similarly to the screw nut or screw ball, mainly pushing the third part 33 to move along the x-axis. However, since the reciprocating screw 38 is provided with two threaded grooves 380 with opposite helical directions and interconnection, the moving part 35 needs to have rotational freedom to switch between the two helical grooves 380.

[0053] Specifically, the guide member 37 is used to prevent rotation and restrict movement, ensuring that the third component 33 can move accurately along the x-axis. The guide member 37 is a sleeve, fixedly fitted onto the outer periphery of the reciprocating screw 38 and secured to the housing of the second drive unit 39 via its flange or by threaded connection to the housing of the second drive unit 39. The guide member 37 has a guide hole 370 extending along the x-axis and connecting the reciprocating screw 38 and the third component 33. The guide hole 370 has a first inlet 3701 in the x-axis direction, opening towards the negative x-axis. Furthermore, the outer periphery of the guide member 37 is hexagonal prism-shaped.

[0054] The inner circumferential contour of the cylindrical wall of the third piece 33 is hexagonal prism, and the cylindrical wall of the third piece 33 is provided with a protrusion 332. The protrusion 332 protrudes towards the reciprocating lead screw 38 on its inner circumference and extends along the x-axis. Thus, when the third piece 33 is fitted onto the outer circumference of the guide piece 37, the polygonal inner circumferential surface of the third piece 33 mates with the polygonal outer circumferential surface of the guide piece 37, and the protrusion 332 is inserted into the guide hole 370. Under this engagement, the third piece 33 and the guide piece 37 slide together along the x-axis, and the third piece 33 cannot rotate relative to the guide piece 37.

[0055] The third component 33 has a cylindrical wall including a mounting port 330 that extends radially through the piston 12 between the inner and outer sides of the cylindrical wall. The extended end of the protrusion 332 has a cross-section that is concave first arc portion 331. The axis of the first arc portion 331 is radially along the piston 12, and the mounting port 330 extends through the piston to the axis of the first arc portion 331. Additionally, the third component 33 has a second inlet 3301 in the x-axis direction, opening towards the negative x-axis and directly opposite the first arc portion 331. The connecting member 34 is detachably mounted from the outer periphery of the third component 33 in the mounting port 330. The connecting member 34 has a concave second arc portion 341. The first arc portion 331 and the second annular portion are opposite each other, forming a shaft hole between them. In this case, the first arc portion 331, the second arc portion 341, and the second inlet are sequentially arranged along the x-axis direction.

[0056] The moving part 35 has a shaft 351 and a moving body 352 at its two opposite ends. The moving body 352 includes two cones located on opposite sides of the axis of the shaft 351. The two cones can guide when switching the threaded groove 380. The moving part 35 passes through the guide hole 370 and slides in the guide hole 370 along the x-axis. The shaft 351 of the moving part 35 is rotatably engaged with the shaft hole formed on the third part 33 between the first arc portion 331 and the second annular portion. The moving body 352 of the moving part 35 engages with the threaded groove 380 of the reciprocating lead screw 38. This utility model is equipped with a detachable connector 34, and a second inlet 3301 combined with a guide 3701 of a third component 33. Both the first inlet 3701 and the second inlet 3301 are used to allow the moving component 35 to enter along the x-axis direction. This arrangement allows the guide 37 and the third component 33 to be assembled without obstruction by the moving component 35. Finally, the connector 34 is installed to restrict the moving component 35 and give the moving component 35 a degree of rotational freedom.

[0057] See Figure 1 The propulsion component also includes a sealing ring 36 fitted over the third component 33; the first housing 93 is fitted over the third component 33, and the sealing ring 36 abuts against the inner circumferential surface of the first housing 93. This arrangement separates the space where the drive unit is located from the space where the piston module is located by the sealing ring 36, thus providing better protection for the motor and circuitry.

[0058] See Figure 1 The body sleeve 92 is fitted onto the outer periphery of the first housing 93 and the second housing 94 and engages with them. See also Figure 7The head cover 91 is provided with an ejection channel 911, which is fitted over the piston tube 11 and communicates with the ejection port 1101. A second engaging structure group is provided between the head cover 91 and the piston tube 11. The second engaging structure group includes a third engaging structure 118 located on the outer periphery of the piston tube 11 and a fourth engaging structure 918 located on the inner periphery of the head cover 91. One of the third engaging structure 118 and the fourth engaging structure 918 is a radial protrusion along the piston, and the other is a radial groove. The third engaging structure 118 and the fourth engaging structure 918 cooperate to fix the relative position of the head cover 91 and the piston tube 11 in the x-axis direction. The head cover 91 provides a more skin-friendly and gentle touch to the head of the assisted reproductive device, avoiding pain even when the vibration module is operating in a strong vibration mode, thus ensuring a strong stimulation sensation without discomfort and improving the user experience.

[0059] Mainly, this invention retains the integration of the vibration module 2 into the assisted reproductive device, but unlike existing vibration-type assisted reproductive devices, the vibration module 2 of this invention is located inside the piston 12, which is very close to the head of the assisted reproductive device. This arrangement allows for better transmission of vibration to the head of the device. Therefore, before and during insertion, the user can experience stimulation from the vibration of the device head to alleviate resistance, relax the mind and body, and moisten the vagina and its entrance environment, making insertion more comfortable and smooth. Once the device is in place, the user does not need complex and cumbersome stretching and pushing operations; simply pressing button 97 controls the propulsion module 3 to automatically pump out semen to complete the assisted reproduction.

[0060] Furthermore, the vibration module 2 is positioned on the assisted reproductive device near the head, and it is also desirable to electrically push and pump out semen to further reduce the difficulty of user operation. At this point, it is necessary to consider and resolve the coordination and feasibility of the layout and assembly structure of the piston module 1, vibration module 2, and propulsion module 3. Therefore, this invention also coordinates the layout, assembly, and positional relationships of the piston module 1, vibration module 2, and propulsion module 3 to ultimately meet the positional requirements and other operational requirements of the vibration module 2.

[0061] The assisted reproductive device of this invention can improve the physiological and psychological state before and during insertion, making the assisted reproductive process smoother and easier.

[0062] Second embodiment of assisted reproductive device

[0063] See Figure 8Unlike the first embodiment, this embodiment also includes a detection module 41 and a detected component 42. The detected component 42 is a magnet and is fixedly installed outside the third component 433. The detection module 41 is disposed on the first housing 493 and includes two detection units 411 spaced apart along a straight line. Both detection units 411 are Hall elements. When the propulsion member is at the first extreme position in the straight line, the detected component 42 is within the detection range of one of the detection units 411; when the propulsion member is at the second extreme position in the straight line, the detected component 42 is within the detection range of the other detection unit 411. Thus, when the propulsion member moves forward and backward to the corresponding extreme positions, it can be sensed, and the motor of the propulsion module can be controlled to start and stop according to the corresponding sensing signals.

[0064] In addition, in this embodiment, a one-way valve 44 is also provided on the outer sleeve of the ejection end corresponding to the ejection port of the piston tube. Of course, the head cover is also fitted on the outer sleeve of the one-way valve 44. Under normal conditions, the one-way valve 44 blocks the ejection port. After the piston moves forward and the pressure in the semen storage space increases, the one-way valve 44 will open and make the ejection port open.

[0065] Third embodiment of assisted reproductive device

[0066] In the first embodiment, the semen can be automatically drawn into the storage space by the retraction of the piston driven by the retraction of the propulsion component. In contrast to the first embodiment, this embodiment requires manual drawing.

[0067] See Figure 9 In this embodiment, unlike the first embodiment, the first piece 51 is not sleeved with the piston 52, and this embodiment also includes an internal piece 53 that is not present in the first embodiment.

[0068] Combined Figures 10 to 12 In fact, the inner component 53 is a component for detachable connection with the pull rod 54. The piston 52 is fitted outside the inner component 53, that is, the inner component 53 is located inside the second cavity of the piston 52, while the first piece 51 is located outside the piston 52 and abuts against the inner component 53 in a straight direction. The first piece 51 and the inner component 53 have no other connection relationship. In this configuration, when the propulsion member moves forward, the first piece 51 pushes the inner component 53 forward, and the piston 52 also moves forward. Figure 9 (as shown, it moves to the left), but when the first piece 51 moves backward, the inner part 53 and the piston 52 will remain in their original positions and separate from the first piece 51.

[0069] See Figure 11 and Figure 12The inner component 53 is provided with a screw hole 530, which is through in a straight line. On the projection of the straight line, the screw hole 530 passes through the center of the inner component 53 and is in the shape of a straight line. In addition, it can be seen that a baffle 531 and a stop block 532 are respectively provided on opposite sides of the straight screw hole 530. The stop block 532 protrudes in a straight line relative to the baffle 531. The two baffles 531 on both sides of the screw hole 530 are symmetrically arranged about the center of the inner component 53. The two stop blocks 532 on both sides of the screw hole 530 are symmetrically arranged about the center of the inner component 53.

[0070] See Figure 12 This embodiment also includes an independent drawer rod 54. Of course, other embodiments may not include the drawer rod, which needs to be provided separately by the user. The front end of the drawer rod 54 is a straight-line screw 541. The screw 541 passes through the center line of the drawer rod 54, and the screw 541 and the main body end face 542 of the drawer rod 54 are connected by a connecting post to form a gap 543. In the straight direction, the size of the gap 543 is larger than the size of the baffle 531 but smaller than the size of the stop block 532.

[0071] The swivel 541 can pass through the swivel hole 530, which is also in a straight line. Then, the swivel 541 is rotated so that its straight arm aligns with the baffle 531 in a straight line. At this point, the baffle 531 is located in the gap 543, and the swivel 541 and the baffle 531 mutually restrict each other in a straight line. Thus, through the detachable connection between the swivel hole 530 and the swivel 541 of the pull rod 54, the internal component 53 and the pull rod 54 can be detachably connected. After connection, the piston can be retracted by pulling the pull rod 54. Additionally, when installing the pull rod 54, the stop 532 can restrict the rotation of the swivel 541, indicating to the user that it has been rotated to the correct position.

[0072] Of course, the user can only insert the pull rod 54 into the internal component 53 after the piston module is disassembled. For this reason, the piston module is also set to be detachable in this embodiment, that is, the piston tube, piston 52 and internal component 53 can be disassembled at the same time. When the piston tube is in the disassembled state, the screw hole 530 is exposed.

[0073] Of course, in this embodiment, although the propulsion module is not connected to the piston, the vibration of the propulsion module, where the vibration module is located, is in close contact with the internal components, so the vibration of the vibration module can also be well transmitted to the piston module and the head of the assisted reproductive device.

[0074] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
