Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically to a uterine support. Background Technology
[0002] Uterine prolapse is a common pelvic organ prolapse disorder in women. Due to the relaxation and weakness of the pelvic fascia, ligaments, and muscles, the uterus cannot provide sufficient support, causing it to descend from its normal position along the vagina, with the external os of the cervix reaching below the level of the ischial spines, or even the entire uterus protruding outside the vaginal opening. This can lead to various gynecological inflammations such as increased vaginal discharge and bleeding, and is usually caused by factors such as childbirth, aging, decreased estrogen levels, and increased abdominal pressure. A pessary is a medical device used to treat uterine prolapse in women; commonly used pessaries include circular pessaries, circular pessaries with membranes, and circular pessaries with handles.
[0003] However, most existing pessaries are difficult to put on and take off, and many patients need to go to the hospital for at least 14 days with the help of a doctor, which causes inconvenience to their lives. At the same time, some pessaries only focus on their load-bearing capacity and ignore their own lightweight design, resulting in low patient comfort after placement. Utility Model Content
[0004] This application provides a pessary that can solve the technical problems of existing pessaries, such as difficulty in putting on and taking off, inconvenience for patients to operate on their own, and the fact that traditional pessaries only focus on their load-bearing capacity while ignoring their own lightweight design, resulting in low patient comfort after use.
[0005] This application provides a uterine pessary, comprising:
[0006] A support assembly, comprising a double-layered insert housing with a top diameter that increases sequentially from top to bottom and is hollow inside, wherein the outer surface of the double-layered insert housing is provided with protruding units for increasing friction, and the protruding units include multiple flexible protruding ribs equidistantly arranged on the outer surface of the double-layered insert housing to cover a certain area of the outer surface of the double-layered insert housing;
[0007] The push assembly includes a flexible connecting rod located at the bottom of the double-layer insert housing and having a diameter smaller than that of the double-layer insert housing. A hand grip unit is provided at the end of the flexible connecting rod away from the double-layer insert housing.
[0008] In one embodiment, the double-layered insertion housing includes a flexible outer shell and a supporting inner shell connected to the inner wall of the flexible outer shell.
[0009] In one embodiment, the flexible protruding ribs are arranged laterally around the outer circumference of the double-layer insert housing, and multiple flexible protruding ribs are arranged longitudinally along the double-layer insert housing.
[0010] In one embodiment, the coverage area of the plurality of flexible protruding ribs is not less than 50% of the area of the double-layer embedded shell.
[0011] In one embodiment, the flexible protruding ribs are longitudinally disposed on the outer surface of the double-layer insert housing, and multiple flexible protruding ribs are arranged laterally along the double-layer insert housing.
[0012] In one embodiment, the plurality of the flexible protruding ribs cover the entire outer surface of the double-layered insertion housing.
[0013] In one embodiment, the grip unit includes a grip ball joint that is fixedly connected to the flexible connecting rod to form an integral grip ball joint.
[0014] In one embodiment, the diameter of the hand-grip ball joint is larger than the diameter of the flexible connecting rod.
[0015] In one embodiment, the double-layered insertion shell is spherical.
[0016] In one embodiment, the double-layered insertion shell is a cone shape with a smooth surface at the top and an outer diameter that increases sequentially from top to bottom.
[0017] The beneficial effects of the technical solutions provided in this application include:
[0018] 1. The uterine pessary in this application has a double-layered insert shell with a top diameter that increases from top to bottom, which can reduce the resistance when the patient pushes the uterine pessary in by himself. The double-layered insert shell is hollow, which can reduce the overall weight of the uterine pessary and improve the patient's comfort. At the same time, the hand grip unit set at the bottom of the double-layered shell is used by the patient to hold the pessary, which makes it easier to exert force when putting on and taking off the uterine pessary, thus improving the ease of operation of putting on and taking off the uterine pessary.
[0019] 2. The uterine pessary in this application has multiple flexible protruding ribs on the double-layered insertion shell that protrude from the outer surface of the double-layered insertion shell. This increases the friction between the uterine pessary body and the human body during insertion, ensuring the stability of the uterine pessary. Attached Figure Description

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.
[0028] This application provides a pessary that solves the technical problems of traditional pessaries, which are difficult to put on and take off, inconvenient for patients to operate on their own, and which only focus on their load-bearing capacity while ignoring their own lightweight design, resulting in low patient comfort after use.
[0029] Figure 1 A frontal view of a uterine support provided for an embodiment of this application, such as... Figure 1 As shown, the uterine pessary in this application includes a support component and a push component. The support component is mainly used to support the patient's uterus, and its weight is the main source of the uterine pessary's weight. Therefore, the material of the support component in this application is lightweight while ensuring a certain rigidity. The push component is mainly used by the patient to hold the uterine pessary, making it convenient for the patient to put on and take off the uterine pessary by themselves.
[0030] Specifically, the support assembly includes a double-layered housing 1 with a top diameter that increases sequentially from top to bottom and is hollow inside. The outer surface of the double-layered housing 1 is provided with protruding units for increasing friction. The protruding units include multiple flexible protruding ribs 2 that are equidistantly arranged on the outer surface of the double-layered housing 1 to cover a certain area of the outer surface of the double-layered housing 1.
[0031] The diameter of the top (or upper half) of the double-layered insert shell 1 increases from top to bottom, which reduces the cross-sectional area and resistance when the patient pushes the uterine pessor in. The double-layered insert shell 1 adopts a hollow design to achieve material lightweighting and reduce the overall weight of the uterine pessor. At the same time, the flexible protruding ribs 2 are higher than the outer surface of the double-layered insert shell 1, which increases the friction between the uterine pessor and human tissue after the uterine pessor is pushed into place, preventing the uterine pessor from falling off.
[0032] As an optional embodiment, based on actual usage, the maximum diameter of the double-layer implant shell 1 can be selected as 40mm, 45mm, 50mm, 55mm or 60mm according to the patient's needs. The above dimensions are for reference only, and the specific dimensions are determined according to actual usage needs, and are not limited in this application.
[0033] Furthermore, the pushing component includes a flexible connecting rod 3 located at the bottom of the double-layer insertion shell 1 and having a diameter smaller than that of the double-layer insertion shell 1. A hand grip unit 4 is provided at the end of the flexible connecting rod 3 away from the double-layer insertion shell 1. The flexible connecting rod 3 is mainly used to connect the double-layer insertion shell 1 and the hand grip unit 4. The patient holds the hand grip unit 4, which makes it easier to apply force and improves the convenience of the operation of putting on and taking off the uterine support.
[0034] Furthermore, Figure 2 A cross-sectional view of a uterine pessary provided in an embodiment of this application, such as... Figure 2 As shown, the double-layered implantable shell 1 includes a flexible outer shell 101 and a supporting inner shell 102 connected to the inner wall of the flexible outer shell 101. The flexible outer shell 101 and the supporting inner shell 102 are tightly fitted together to form a single unit. The supporting inner shell 102 has a certain rigidity to ensure the shaping of the pessary. The flexible outer shell 101 is in direct contact with the human body and is made of a flexible material to improve the overall comfort of using the pessary.
[0035] As an optional embodiment, the flexible outer shell 101 is made of medical-grade silicone material, which has minimal reaction to human tissue and hardly causes foreign body reactions or inflammation. It also has good elasticity and flexibility and can maintain its physical properties over a wide temperature range. The aforementioned flexible protruding ribs 2 are disposed on the flexible outer shell 101 and form an integral part of the flexible outer shell 101. Therefore, the material of the flexible protruding ribs 2 is the same as that of the flexible outer shell, which is also made of medical-grade silicone material. The supporting inner shell 102 is made of ABS resin material, which has high strength, toughness and good impact resistance. While ensuring the rigidity of the material, reducing the thickness of the supporting inner shell 102 can also help with lightweight design.
[0036] Furthermore, as a first embodiment of the flexible protruding rib 2, the flexible protruding rib 2 is arranged laterally around the outer circumference of the double-layer insertion shell 1, and multiple flexible protruding ribs 2 are arranged longitudinally along the double-layer insertion shell 1. That is, in this embodiment, a single flexible protruding rib 2 is arranged laterally around the outer circumference of the double-layer insertion shell 1, and multiple flexible protruding ribs 2 are arranged longitudinally, and the coverage area of the multiple flexible protruding ribs 2 is not less than 50% of the area of the double-layer insertion shell 1. In conjunction with the above description, the top diameter of the double-layer insertion shell 1 gradually increases from top to bottom. Therefore, the friction and compression force between the double-layer insertion shell 1 and human tissue also increase sequentially from top to bottom. Therefore, in this application, the main setting area of the flexible protruding rib 2 is located in the area with a smaller diameter above the double-layer insertion shell 1, and in order to ensure effective friction, the coverage area of the flexible protruding rib 2 is not less than 50% of the area of the double-layer insertion shell 1.
[0037] As a second embodiment of the flexible protruding rib 2 Figure 3 This application provides a schematic diagram of one embodiment of a flexible protruding rib 2 in a uterine pessary, as shown in the following example. Figure 3 As shown, flexible protruding ribs 2 are longitudinally arranged on the outer surface of the double-layer insertion shell 1, and multiple flexible protruding ribs 2 are arranged laterally along the double-layer insertion shell 1. That is, in this embodiment, a single flexible protruding rib 2 is arranged longitudinally, that is, in accordance with the direction of uterine support up and down. Compared with the flexible protruding ribs 2 arranged laterally, the friction between the vertically arranged flexible protruding ribs 2 and the human body is reduced. However, the vertically arranged flexible protruding ribs 2 can be arranged in accordance with the direction of uterine support up and down, making the operation of uterine support up and down easier. At the same time, in order to compensate for the reduced friction due to the vertical arrangement, in this embodiment, multiple flexible protruding ribs 2 cover the entire outer surface of the double-layer insertion shell 1. Based on this structure, the contact area between the flexible protruding ribs 2 and the human body component is increased, and the friction is also enhanced.
[0038] Furthermore, the hand-grip unit 4 includes a hand-grip ball joint that is fixedly connected to the flexible connecting rod 3 to form an integral part. One end of the flexible connecting rod 3 is fixedly connected to the double-layer insertion shell 1 to form an integral part, and the overall material of the flexible connecting rod 3 is consistent with that of the double-layer insertion shell 1. In conjunction with the above description, the flexible connecting rod 3 is also made of medical-grade silicone material. The flexible connecting rod 3 is mainly used to increase the distance between the double-layer insertion shell 1 and the hand-grip ball joint to facilitate the patient's hand gripping of the hand-grip ball joint. Therefore, the diameter of the flexible connecting rod 3 is smaller than the diameter of the hand-grip ball joint. In one embodiment of this application, the flexible connecting rod 3 is a cylinder with a length of 2.5 cm and a diameter of 1 cm, so that the flexible connecting rod 3 can withstand the inward pushing force applied by the patient toward the uterine pessary. The above dimensions are for reference only, and the specific dimensions are determined according to the actual use requirements and are not limited in this application.
[0039] Furthermore, the hand-grip joint is a solid sphere, facilitating the patient's application of force. In one embodiment of this application, the difference between the diameter of the hand-grip joint and the diameter of the flexible connecting rod 3 is between 0.2 and 0.5 mm. As an optional embodiment, the hand-grip joint is made of a medical material containing silver ions, which has broad-spectrum antibacterial properties and can effectively inhibit the growth and reproduction of bacteria, fungi, and other microorganisms.
[0040] Furthermore, the double-layered housing 1 has diverse forms. Figure 4 This is a schematic diagram of one embodiment of a double-layered insert shell 1 in a uterine pessary provided in this application. Figure 5 This is a schematic diagram of another embodiment of a double-layered insert shell in a uterine pessary provided in this application, as shown in the example. Figure 4 , Figure 5 As shown, the double-layered housing 1 includes spherical and conical shapes with a smooth top surface and an outer diameter that increases from top to bottom, etc. Other shapes are also possible, but regardless of the shape, the condition that "the top diameter increases from top to bottom and the whole is rounded without sharp edges" must be met.
[0041] It should be noted that the above-mentioned improvement of the flexible protruding rib 2 includes two implementation methods: horizontal and vertical arrangement. The shape of the double-layer insertion shell 1 also includes two implementation methods: spherical and conical. The above methods can be freely combined. Therefore, in this application, the shape of the uterine pessary includes at least four types, namely: a conical double-layer insertion shell 1 with a horizontal flexible protruding rib 2, a conical double-layer insertion shell 1 with a vertical flexible protruding rib 2, a spherical double-layer insertion shell 1 with a horizontal flexible protruding rib 2, and a spherical double-layer insertion shell 1 with a vertical flexible protruding rib 2. The above four methods can be freely combined and modified, and no specific restrictions are imposed in this application.
[0042] The uterine pessary in this application has a double-layered insert shell 1 with the top diameter increasing from top to bottom, which can reduce the resistance when the patient pushes the uterine pessary in by himself. The double-layered insert shell 1 is hollow, which can reduce the overall weight of the uterine pessary and improve the patient's placement comfort. At the same time, the hand grip unit 4 set at the bottom of the double-layered insert shell 1 is used by the patient to hold it, which makes it easier to exert force when putting on and taking off the uterine pessary, thus improving the convenience of the operation of putting on and taking off the uterine pessary.
