Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a vaginal tightening stick for gynecological pelvic muscle relaxation recovery. Background Technology

[0002] In the field of gynecological rehabilitation, pelvic floor muscle relaxation is a common women's health problem, especially prevalent among postpartum women and middle-aged and elderly women. Pelvic floor muscle relaxation can lead to various adverse symptoms, such as urinary incontinence, vaginal prolapse, and even uterine prolapse, seriously affecting women's quality of life and mental health. Therefore, effectively restoring pelvic floor muscle tone and improving vaginal tightness has become an important topic in gynecological rehabilitation treatment.

[0003] As a physical rehabilitation tool, vaginal tightening sticks are gradually gaining attention in clinical and home rehabilitation. The basic principle of vaginal tightening sticks is to place a weighted instrument inside the vagina, combined with the woman's own pelvic floor muscle training, thereby strengthening the pelvic floor muscles and improving pelvic muscle relaxation. In recent years, with technological advancements, some vaginal tightening stick products have incorporated injection channels into the stick itself, allowing for direct delivery of medication into the vagina during use, combining physical training with drug therapy to enhance treatment effectiveness. However, while existing vaginal tightening sticks have injection channels, their injection methods are mostly single-use or one-time administration, which is insufficient to meet the needs of multiple, continuous administration required in clinical treatment. Furthermore, the injection operation of existing vaginal tightening sticks usually requires the use of external syringes or other auxiliary equipment, making the process cumbersome and inconvenient. Therefore, this paper proposes a vaginal tightening stick for gynecological pelvic muscle relaxation recovery. Summary of the Invention

[0004] In view of the fact that the existing technology of vaginal tightening sticks is mostly a one-time injection or single administration, which is difficult to meet the needs of clinical treatment for multiple and continuous administration, and the injection operation usually requires the use of external syringes or other auxiliary equipment, which is cumbersome and inconvenient to use, the purpose of this invention is to provide a vaginal tightening stick for gynecological pelvic muscle relaxation recovery.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0043] like Figures 1 to 4 As shown, this embodiment of the invention provides a vaginal tightening stick for gynecological pelvic muscle relaxation recovery, including a stick body 1, a locking mechanism 7, and an injection head 2 installed at one end of the stick body 1. The stick body 1 is cylindrical in shape, which facilitates vaginal placement and removal. Multiple sets of grooves 4 are opened inside the stick body 1. The grooves 4 are linearly and equidistantly distributed. Each groove 4 is provided with a drug storage mechanism 5 and a needle puncture mechanism 6. The drug storage mechanism 5 includes a drug storage sac 51 and a connecting groove 54. The drug storage sac 51 is located inside the groove 4, and the connecting groove 54 is opened on the side of the groove 4 near the injection head 2. The drug storage sac 51 is located between the connecting groove 54 and the needle puncture mechanism 6, and the needle of the needle puncture mechanism 6 is arranged opposite to the connecting groove 54. The side of the drug storage sac 51 near the injection head 2 is fixedly connected to the inner surface of the groove 4. The connecting groove 54 and the injection head 2 are connected by an injection tube.

[0044] With the injection head 2 as the first end, the locking mechanism 7 is used to fix the position of the first acupuncture mechanism 6. Each of the two adjacent acupuncture mechanisms 6 is provided with a support mechanism 8. When the locking mechanism 7 is in the locked state, the acupuncture mechanisms 6 are all in the fixed state. When the locking mechanism 7 is in the unlocked state, the drug storage sac 51 is punctured sequentially starting from the first acupuncture mechanism 6 to achieve staged drug delivery.

[0045] like Figure 4 As shown, the injection pipeline includes an injection pipe 52, which is located inside the rod body 1. The connecting groove 54 and the injection pipe 52 are connected through injection branch pipes 53. The connecting groove 54 at the first end is connected to the injection head 2.

[0046] like Figure 3 As shown, the needle-punching mechanism 6 includes a pressure plate 61, a needle 62, and a compression spring 63. The pressure plate 61 is slidably installed inside the groove 4, and the needle 62 is fixedly installed on the surface of the pressure plate 61. The tip of the needle 62 penetrates into the inside of the drug storage bag 51, and the needle 62 and the drug storage bag 51 are sealed together at the penetration point. The needle 62 is arranged opposite to the connecting groove 54, and the compression spring 63 is arranged between the pressure plate 61 and the inner surface of the groove 4.

[0047] like Figure 2 , Figure 6 as well as Figure 8As shown, a fixing mechanism 3 is provided on the rod body 1. The fixing mechanism 3 includes annular grooves 31 on both sides of the outer surface of the rod body 1. Annular bladders 32 are fitted inside the annular grooves 31. The annular bladders 32 are partially fixedly connected to the inner surface of the annular grooves 31. The two sets of annular bladders 32 are connected by a connecting pipe 33. The middle part of the connecting pipe 33 is located inside the rod body 1. An inflation component is provided at the tail end of the rod body 1. The inflation component is used to deliver gas to the annular bladders 32. The inflation component includes an extension pipe 34. One end of the extension pipe 34 is connected to the annular bladder 32 located at the tail end of the rod body 1. The other end of the extension pipe 34 is located outside the rod body 1 and is fixedly connected to a balloon 35. A side pipe 36 is fixedly connected to the outer surface of the extension pipe 34. A valve body 37 is provided inside the side pipe 36 and at the air inlet and outlet ends of the balloon 35.

[0048] In this embodiment, the valve body 37 inside the balloon 35 and the side tube 36 is an important component of the vaginal tightening rod fixing mechanism 3. Its main function is to regulate the inflation and deflation of the annular balloon 32. The valve body 37 at the air inlet end of the balloon 35 is a one-way air inlet valve, allowing external gas to enter the interior of the balloon 35; the valve body 37 at the air outlet end of the balloon 35 is a one-way air outlet valve, allowing gas to enter the interior of the annular balloon 32 through the extension tube 34 and the connecting tube 33; the valve body 37 inside the side tube 36 is a one-way air outlet valve, allowing gas inside the annular balloon 32 to be discharged from the side tube 36, causing the annular balloon 32 to contract, facilitating the removal of the rod 1; the balloon 35 is similar to a manual airbag. By squeezing the balloon 35, air can be delivered to the annular balloon 32, causing it to inflate; by releasing the balloon 35, gas is drawn into the balloon 35. By repeatedly squeezing the balloon 35, continuous inflation can be achieved.

[0049] like Figures 6 to 7 As shown, the locking mechanism 7 includes an annular plate 71, which is movably fitted inside the annular groove 31 located at the head end of the rod 1. A movable plate 72 is fixedly connected to the surface of the annular plate 71. A movable groove 73 and a sliding groove 74 are formed on the inner surface of the rod 1. The movable groove 73 is horizontal and the sliding groove 74 is vertical. One end of the movable plate 72 passes through the rod 1 and is slidably installed inside the movable groove 73 and is fixedly connected to a connecting rope 75. A limit block 77 is slidably connected inside the sliding groove 74. One end of the connecting rope 75 passes through the sliding groove 74 and is fixed to the limit block 77. The connecting rope 75 is fitted with a connecting spring 76 on its outer surface. One end of the connecting spring 76 is fixedly connected to the inner surface of the slide groove 74, and the other end of the connecting spring 76 is fixedly connected to the limiting block 77. A limiting groove 78 is opened on the surface of the pressure plate 61 at the head end of the rod body 1. The limiting block 77 is inserted into the limiting groove 78. The moving direction of the moving plate 72 is parallel to the moving direction of the pressure plate 61. The insertion direction of the limiting block 77 into the limiting groove 78 is perpendicular to the moving direction of the pressure plate 61. When the limiting block 77 is inserted into the limiting groove 78, the connecting rope 75 is taut.

[0050] like Figure 3 and Figure 5 As shown, each support mechanism 8 includes a through groove 81, a baffle 82, a support plate 83, and a solid sustained-release drug 84. The through groove 81 is disposed between two sets of grooves 4, and one side of the through groove 81 is set as an opening. In two adjacent grooves 4, the baffle 82 is fixedly connected to the pressure plate 61 near the first end. The baffle 82 slides through the side wall between the groove 4 near the first end and the through groove 81 to block the opening of the through groove 81. The solid sustained-release drug 84 is located in the closed cavity formed by the baffle 82 and the through groove 81. The side wall away from the first end is in contact. The support plate 83 is provided with a horizontal T-shaped structure. The vertical part of the support plate 83 is located in the through groove 81 and abuts against the solid sustained-release drug 84. The horizontal part of the support plate 83 slides through the side wall between the groove 4 away from the first end and the through groove 81 and abuts against the pressure plate 61 away from the first end. The moving directions of the baffle 82 and the support plate 83 are parallel to the moving direction of the pressure plate 61. The moving length of the baffle 82 and the support plate 83 is not less than the distance from the pressure plate 61 to the near end of the connecting groove 54 when it is locked.

[0051] In this embodiment, initially, the locking mechanism 7 is in a locked state. At this time, the limiting block 77 is inserted into the limiting groove 78 of the pressure plate 61 at the first end, fixing the position of the pressure plate 61 and keeping the needle 62 in a state where it has not punctured the drug reservoir 51. The compression spring 63 is in a compressed state, providing a restoring force for the needle 62. The drug reservoir 51 contains liquid drug and is connected to the injection branch pipe 53 through the connecting groove 54. The injection branch pipe 53 is then connected to the injection pipe 52, and finally connected to the injection head 2. At this time, the drug reservoir 51 is in a sealed state, and the drug is not released.

[0052] After the user places the rod 1 inside the vagina, the inflation component inflates the annular bladder 32, causing it to expand. The annular bladder 32 supports the vaginal wall, improving the stability of the rod 1. Additionally, as the annular bladder 32 expands, it pushes the annular plate 71 to move, causing the moving plate 72 to slide along the moving groove 73. This pulls the connecting rope 75, disengaging the limiting block 77 from the limiting groove 78 and releasing the lock on the pressure plate 61. At this point, the compression spring 63 at the head releases its elasticity, pushing the pressure plate 61 forward. This causes the needle 62 to puncture the drug reservoir 51, releasing the drug from the reservoir 51. The drug then enters the injection branch tube 53 through the connecting groove 54 and is finally delivered to the vaginal area through the injection head 2, initiating drug administration.

[0053] Since the baffle 82 in the support mechanism 8 is fixedly connected to the pressure plate 61, as the pressure plate 61 moves forward, the baffle 82 also moves towards the front end, opening the opening of the through groove 81. The length of the baffle 82 is less than the length of the groove 4, exposing the solid sustained-release drug 84. When the solid sustained-release drug 84 is consumed, the vertical part of the support plate 83 loses its supporting force and moves towards the front end, so that the horizontal part of the support plate 83 no longer abuts against the pressure plate 61 away from the front end. The next set of needle puncture mechanisms 6, i.e., the needle puncture mechanism away from the front end, punctures the drug reservoir 51 and continues to administer the drug. Among them, the solid sustained-release drug 84 can achieve delayed drug release in the vagina. The solid sustained-release drug 84 in this application can be a vaginal gel sustained-release suppository, which has the function of moisturizing and repairing the mucosa. The disintegration time of the solid sustained-release drug 84 can be set according to the actual interval of liquid drug administration.

Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0055] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
