Description

Technical Field

[0001] The utility model relates to the technical field of medical devices for treating gynecological diseases, in particular to a novel antibacterial pessary. Background Art

[0002] Pelvic organ prolapse (POP) is a pelvic floor dysfunction disease with clinical manifestations of vaginal mass prolapse and pelvic pain, often accompanied by bladder, rectal and sexual dysfunction, which seriously affects the patient's quality of life. The disease is more common in middle-aged and elderly women. At the same time as POP, due to factors such as organ ectopy, decreased patient immunity, bacterial imbalance and local acid-base imbalance, pressure ulcers caused by wearing a hard pessary and accompanied by infection, vaginal infection, odor and inflammation occur, greatly increasing the patient's pain and symptoms. At present, the treatment methods of POP are divided into surgical and non-surgical therapies. Non-surgical therapies include lifestyle intervention, pelvic floor muscle training, biofeedback, pessaries, etc. Among them, pessaries are safe, simple and economical to use, and once placed, they can immediately achieve anatomical reduction of the prolapsed organ.

[0003] At present, the pessaries used in clinical practice are roughly divided into two categories: support type and space-filling type. Common support type pessaries include: ring-shaped pessaries, frame-shaped pessaries, etc.; common space-filling type pessaries include: horn-shaped, donut-shaped, cube-shaped, mushroom-shaped, etc. For patients with more serious uterine prolapse, space-filling type pessaries are mostly used clinically, and mushroom-shaped pessaries are the most common representative of space-filling type pessaries. In the actual use of patients, the larger size of the pessary may lead to pressure ulcers after reduction, and the smaller size may make it easy to fall off, and the adsorption capacity is not strong when it comes into contact with the inner wall of the uterus.

[0004] Therefore, the present invention has developed a new antibacterial pessary to solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of the utility model is to provide a novel antibacterial pessary to solve the problems of small uterine supporting area, insufficient adsorption force and pressure ulcer caused by uneven pressure on the force surface in the prior art.

[0006] The technical solution of the present utility model is: a new antibacterial pessary, comprising a pessary body and a pull ring, wherein the outer wall surface of the pessary body is structured with a force-bearing surface, a force-bearing surface and a tension surface; the pull ring is provided on the tension surface, and the force-bearing surface is provided at an end away from the pull ring; at least a portion of the outer wall surface of the pessary body is distributed with recessed portions.

[0007] Preferably, the pessary body is spherical, and the force-bearing surface, the force-bearing surface and the tension surface are combined to form a spherical surface.

[0008] Preferably, the pessary body comprises a first body and a second body that are interlocked with each other, the inner wall surfaces of the first body and the second body are combined to form a complete spherical surface, and the pessary body is hollow after being interlocked.

[0009] Preferably, the first body has a contoured cavity with the same outline shape as the second body, the inner wall of the contoured cavity and the outer wall of the second body are both stepped, and the second body is embedded in the contoured cavity and fixed.

[0010] Preferably, ribs for increasing friction with the contact surface are distributed on the outer wall surface of the pessary body, and the ribs and the recessed portions are staggeredly distributed on the outer wall surface of the pessary body.

[0011] Preferably, the specific surface area of ​​the pessary body is 110 mm 2 / g~150mm 2 / g.

[0012] Preferably, the pull ring has a lifting portion, at least part of the outer wall of the lifting portion has a protrusion for increasing friction, and the width of the pull ring is smaller than the outer diameter of the pessary body.

[0013] Preferably, the radius of the recessed portion is 3 mm to 7 mm, and the depth is 1 mm to 2 mm.

[0014] Preferably, the first body and the second body are formed as one piece by blending silica gel and nano silver particles.

[0015] Preferably, the diameter of the nanosilver particles is 50 μm to 150 μm.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) By providing a concave portion on the outer wall of the pessary body, when it contacts the inner wall of the uterus, the concave portion and the inner wall of the uterus expel air under the action of compression to form a negative pressure, thereby improving the adsorption force between the pessary body and the inner wall of the uterus;

[0018] (2) The pessary body adopts a spherical design, combined with the setting of the concave part, so that the pessary body forms a golf ball-like structure, which increases the specific surface area of ​​the pessary body. When used, the contact area with the cervix and vaginal wall is greatly increased, and the force on each contact surface is evenly distributed, the pressure is smaller, and it is less likely to cause pressure ulcers and subsequently infection;

[0019] (3) The pessary body is hollow, which reduces weight and optimizes the patient's experience;

[0020] (4) The design of the pull ring makes it easy for patients to remove the pessary by themselves. Since the width of the pull ring is smaller than the outer diameter of the pessary body, the contact area between the pull ring and the inner wall of the vaginal mucosa is smaller, further optimizing the user experience.

[0029] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0030] like Figures 1-6As shown, a new type of antibacterial pessary includes a pessary body 1, a pull ring 6, and a rib 7. The outer wall surface of the pessary body 1 includes a force-bearing surface 2, a force-bearing surface 3, and a tension surface 4. A pull ring 6 is provided on the tension surface 4 to facilitate user adjustment and removal. The force-bearing surface 2 is arranged at the end away from the pull ring 6. The force-bearing surface 2 needs to fit tightly with the vaginal wall to ensure that the pessary can be stably fixed in the vagina and is not easy to slip or shift. While supporting the uterus and vaginal wall, it can disperse the pressure from the uterus and vaginal wall, reduce the pressure and discomfort on local tissues, and the force-bearing surface 3 effectively transfers the supporting force received by the force-bearing surface 2 to other parts of the pessary, ensuring that the entire pessary can stably support the uterus and vaginal wall, maintain the correct shape and position of the pessary in the vagina, and prevent it from deformation or failure. Recesses 5 and ribs 7 are staggeredly distributed on the outer wall surface of the pessary body 1.

[0031] Among them, the ribs 7 can increase the rigidity and stability of the pessary, so that it can better support the uterus and vaginal wall, prevent sagging, and ensure that the pessary is not easily deformed when under pressure. The ribs 7 can also disperse the pressure of the pessary on the vaginal wall, reduce the pressure on local tissues, and improve the patient's comfort. At the same time, it can also prevent the pessary from slipping by increasing the contact area and friction with the vaginal wall, so that the pessary is more stably fixed in the vagina; the recessed portion 5 can increase the air permeability of the pessary surface and reduce the contact area with the vaginal wall, thereby reducing the stuffiness and discomfort that may be caused by the patient during use. At the same time, the recessed portion 5 and the inner wall expel air under the action of squeezing, forming a negative pressure, which increases the adsorption force between the pessary and the inner wall of the uterus, making the pessary not easy to fall off. The radius of the recessed portion 5 is 3mm to 7mm, and the depth is 1mm to 2mm. Preferably, the radius of the recessed portion 5 is 5mm and the depth is 1.5mm. The recessed portions of appropriate size can be more evenly distributed on the outer wall of the pessary body 1 and provide better adsorption force, so that the pessary has better stability and support.

[0032] like Figure 1-Figure 2As shown, the pessary body 1 includes a first body 11 and a second body 12 that are interlocked. The inner wall surfaces of the first body 11 and the second body 12 are combined to form a complete spherical surface, and the pessary body 1 is hollow after being interlocked. The hollow structure can significantly reduce the overall weight of the pessary compared to the solid structure, making the patient feel lighter when using it, reducing the pressure on the vagina and surrounding tissues. Due to the reduction in weight and the improvement in stability, the pressure on the surrounding tissues during wearing of the pessary will also be reduced accordingly, avoiding tissue damage caused by long-term pressure. At the same time, the pessary itself The body 1 is ellipsoidal or spherical as a whole. Preferably, the force-bearing surface 2, the load-bearing surface 3 and the tension surface 4 are combined to form a spherical surface. The spherical surface can increase the contact area between the pessary and the cervix and vaginal wall, so that each contact surface is evenly stressed, avoiding excessive pressure on some contact surfaces due to uneven force, thereby causing pressure ulcers. At the same time, the spherical surface can evenly distribute the pressure on the pessary, reduce the pressure on the vaginal wall, and improve the patient's comfort. Moreover, the spherical structure can provide stable support in the vagina, help maintain the normal position of the uterus and vaginal wall, and reduce the risk of uterine prolapse.

[0033] like Figure 2-Figure 3 As shown, the first body 11 has a contoured cavity 13 with the same contour shape as the second body 12. The inner wall of the contoured cavity 13 and the outer wall of the second body 12 are both stepped. The second body 12 is embedded in the contoured cavity 13 and bonded and fixed, which can improve the sealing between the contoured cavity 13 and the second body 12.

[0034] During the manufacturing process, the first body 11 and the second body 12 are respectively formed as one piece by blending liquid silicone and nano-silver particles, so as to avoid the problem of nano-silver coating used in traditional structures, which falls off after entering the human body and causes lifelong toxicity. In this embodiment, the diameter of the nano-silver particles is 50 μm to 150 μm, and the mixing ratio is 100:1 to 100:3, with the preferred ratio being 100:1.2, so that the hardness of the pessary body 1 is maintained at 10A, and the softness and biocompatibility are good. The spherical pessary body 1 and its softness can better fit the physiological structure of the vagina, reduce friction with the vaginal wall, and reduce discomfort. In addition, the pessary body 1 formed by mixing liquid silicone and nano-silver has a certain degree of adaptability and can be fine-tuned according to the shape and size of the vagina to provide a better support effect. Liquid silicone has excellent biocompatibility. It is non-toxic, non-irritating to the human body and will not cause allergic reactions. Nanosilver has strong antibacterial properties and can effectively inhibit the growth of various bacteria, fungi and viruses. Combining nanosilver particles with liquid silicone in a ratio of 100:1.2 can further enhance the antibacterial ability of the pessary and reduce the risk of infection. Its softness and elasticity enable the liquid silicone pessary to better adapt to the physiological structure of the vagina, reduce friction and discomfort with the vaginal wall, and after the liquid silicone and nanosilver are blended into one piece, the pessary can be used repeatedly and can maintain a stable shape and performance during long-term use, and is not easy to age or deform.

[0035] In order to further increase the contact area between the pessary and the human body, the specific surface area of ​​the pessary body 1 is set to 110mm 2 / g~150mm 2 / g, preferably 120mm 2 / g, enhance the supporting effect, keep the uterus and vaginal walls in place more stably, and reduce the risk of prolapse. The larger specific surface area of ​​the pessary helps to disperse the pressure of the pessary on local tissues, thereby improving the patient's comfort. If the specific surface area of ​​the pessary is relatively small, the pessary will not be able to provide sufficient support to prevent the uterus and vaginal walls from falling off, resulting in poor treatment effect or the need to adjust or replace the pessary more frequently. In addition, the smaller specific surface area of ​​the pessary may cause uneven distribution of pressure on local tissues, thereby increasing discomfort or pain, and even causing damage to local tissues. If the specific surface area of ​​the pessary is too large, it may make the pessary more difficult to place or remove correctly, or cause the patient to feel discomfort during activities, resulting in pressure ulcers due to excessive local pressure.

[0036] To facilitate the replacement of the pessary, the lifting portion 61 of the pull ring 6 is provided with a protrusion 62 that increases friction. This allows the patient or medical staff to more easily and stably grasp the pull ring 6 to place, adjust, or remove the pessary. This also helps to prevent the pessary from accidentally slipping or moving during operation, thereby improving the accuracy and efficiency of the operation. When the pessary needs to be adjusted or replaced, these protrusions 62 provide sufficient friction, allowing the operator to easily grasp the pull ring 6 and operate without slipping, which may lead to failure or injury. Furthermore, the width of the pull ring is smaller than the outer diameter of the pessary body, which reduces the contact area with the inner wall of the vaginal mucosa during use, thus optimizing the patient experience.

[0037] The implementation principle of the embodiment of this application:

[0038] After the pessary is placed in the human body, the outer wall of the pessary body 1 contacts the cervix and vaginal wall, the force-bearing surface 2 is in close contact with the cervix and vaginal wall for support to prevent the uterus from falling off, and the force-bearing surface 3 is in contact with the vaginal wall to support the pessary and prevent it from falling off. The ribs 7 can increase the friction to make the pessary more stable. At the same time, the air is discharged under the action of the concave part 5 and the inner wall, forming a negative pressure that acts like a suction cup, thereby increasing the adsorption force of the pessary on the inner wall of the uterus, making it difficult for the pessary to fall off. The larger specific surface area can play a better supporting role, and will not cause pressure ulcers due to excessive specific surface area or cause the pessary to fall off easily due to too small a specific surface area. The pull ring 6 is convenient for patients or medical personnel to place and adjust the pessary.
