Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0036] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] Example 1

[0038] like Figure 1-Figure 3 As shown, the embodiment of the present utility model application provides a new vaginal dilator, including: a fixing ring 1, an expansion structure 2, an air bag 3 and an inflation device 4.

[0039] The expansion structure 2 is connected to the fixed ring 1, and a channel 10 with two ends extending therethrough is formed on the inner side of the fixed ring and the expansion structure; the airbag 3 is arranged on the inner side of the expansion structure 2, that is, the airbag 3 is arranged in the channel 10 and away from the fixed ring 1; the inflation device 4 is connected to the airbag 3 and is used to inflate and deflate (deflate) the airbag 3.

[0040] Under the action of the airbag 3, the expansion structure 2 has a first, collapsed state and a second, expanded state. In its initial state (when the airbag 3 is uninflated), the expansion structure 2 is in the collapsed state. During use, the vaginal dilator is inserted into the patient's vagina in the collapsed state. Then, gas is injected into the airbag 3 via the inflation device 4, causing the airbag 3 to inflate and expand the expansion structure 2, shifting the expansion structure from the collapsed state to the second, expanded state, thereby expanding the patient's vagina. At this point, medical personnel can perform procedures such as vaginal examination and sampling. The airbag 3 gradually expands the expansion structure 2, helping to reduce vaginal stiffness. Furthermore, the expansion can be adjusted to the size of the patient's vagina, making adjustment convenient and controllable. Specifically, by adjusting the volume of the airbag, the expansion of the expansion structure 2 can be controlled, thereby avoiding discomfort or injury to the patient and improving patient comfort.

[0041] Optionally, the fixing ring 1 is made of a polymer material.

[0042] Optionally, the expansion structure 2 includes a plurality of skeletons 21 , and the plurality of skeletons 21 are distributed in a ring shape at one end of the fixing ring 1 .

[0043] Optionally, there are at least two skeletons 21. The number of skeletons 21 can be flexibly configured as needed. When the number is an even number, they are arranged symmetrically in pairs. When the number is an even number, they are evenly spaced. In this embodiment, there are preferably four skeletons 21, and the following embodiments are mainly described based on this situation.

[0044] Specifically, the skeleton 21 comprises a connecting portion and a gripper portion connected to one end of the connecting portion. The lower portion near the fixed ring 1 is the connecting portion, one end of which is connected to the fixed ring 1. The upper portion away from the fixed ring 1 is the gripper portion. The connecting portion and the gripper portion are an integral structure, and the airbag 3 is disposed inside the gripper portion. Optionally, the airbag 3 is disposed near one end of the connecting portion.

[0045] In one embodiment, the width of the skeleton 21 gradually increases from one end of the fixing ring 1 to the other end, that is, the width of the claw portion is greater than that of the connecting portion.

[0046] In one embodiment, the thickness of the skeleton 21 gradually increases from one end of the fixing ring 1 to the other end, that is, the thickness of the claw portion is greater than the thickness of the connecting portion.

[0047] In one embodiment, the outer wall of the end of the frame 21 away from the fixing ring 1 is curved. Specifically, the outer wall of the claw hand is formed with an inclined section 211, a curved section 212, and a connecting section 213 from top to bottom. Optionally, the inclined section 211 is inclined from the end of the frame 21 toward the curved section 212, and the curved section 212 has an arc-shaped structure. The connecting section 213 is gradually inclined inward from one end of the curved section 212. When the frame 21 is expanded, the curved section 212 can better fit the patient's vagina. The curved section 212 can increase the contact area with the vagina, improve the expansion effect, and disperse external force to improve force uniformity, which helps to reduce patient discomfort and increase comfort.

[0048] As an implementation scenario, in this scenario, one end of the frame 21 is hinged to the fixing ring 1. When the airbag 3 is inflated, the frame 21 is expanded outward under the action of the airbag 3, that is, the frame 21 expands outward counterclockwise around the hinged end. Optionally, the frame 21 is made of an elastically deformable material.

[0049] As another implementation scenario, in this scenario, the frame 21 is made of an elastically deformable material. In this scenario, the elastic material frame 21 can be integrally formed with the fixing ring 1. When the airbag 3 is inflated, the end of the frame 21 away from the fixing ring 1 can expand outward in the direction of the airbag 3.

[0050] As an implementation scenario, in this scenario, when the airbag 3 is inflated, the multiple skeletons 21 are stretched to form a trumpet shape, and when the airbag 3 is deflated, the multiple skeletons 21 surround to form a cylindrical shape; that is, in this implementation scenario, the first state is a cylindrical shape (refer to Figure 1 As shown), the second state is a bell-mouth shape (refer to Figure 2 shown).

[0051] Optionally, the inflation device 4 is an air pump, which is arranged on the outside of the channel 10 and is connected to the airbag 3 through an air tube 41. One end of the air tube 41 is connected to the airbag 3, and the other end is connected to the output end of the air pump.

[0052] In one embodiment, a pressure sensor 5 is provided on the airbag 3. The pressure sensor 5 and the air pump are both electrically connected to the controller. The pressure sensor 5 is used to sense the pressure value of the airbag 3. The controller receives the communication data of the pressure sensor 5 and controls the air pump. As one implementation scenario, in this scenario, the pressure sensor 5 can be directly provided on the airbag 3. As another implementation scenario, in this scenario, the pressure sensor 5 is provided at the connection between the airbag 3 and the skeleton 21. During use, after the airbag 3 is inflated, the pressure sensed by the pressure sensor 5 is displayed by the display module on the controller. Medical staff can control the volume of the airbag 3 by regulating the inflation or deflation of the air pump to prevent the skeleton from expanding too much due to the larger volume of the inflated airbag 3, thereby affecting the comfort or causing harm to the patient.

[0053] In one embodiment, an inclined surface 214 is provided on the inner wall of one end of the frame 21 away from the fixing ring 1 . The inclined surface 214 is inclined inward from the end of the frame 21 .

[0054] During use, the vaginal dilator in a folded state is inserted into the patient's vagina, and then gas is injected into the airbag 3 through the inflation device 4. The airbag 3 inflates and expands the multiple skeletons 21, so that the expansion structure is transformed from a folded state to a second state of outward expansion, thereby expanding the patient's vagina. At this time, medical staff can perform operations such as inspection and sampling on the patient's vagina.

[0055] Example 2

[0056] like Figure 4-Figure 7 As shown, the embodiment of the present utility model provides a novel vaginal dilator. Based on the embodiment 1, in this embodiment, a collection platform 6 is provided at the end of the frame 21 away from the fixing ring 1. The outer diameter of the collection platform 6 is smaller than the outer diameter of the curved section 212. The collection platform 6 is provided with a collection groove. In this embodiment, the collection groove on the collection platform 6 is used to collect and remove vaginal secretions, blood, and other liquids in a timely manner, which facilitates observation and operation by medical personnel.

[0057] As an implementation scenario, in this scenario, a liquid absorption structure is provided on the collection tank. When in use, the liquid is absorbed by the absorption structure. The absorption structure can be a composite layer consisting of a disinfection layer, a water-permeable layer, absorbent paper, a water-absorbing resin layer, a fluff pulp layer, etc.

[0058] As another implementation scenario, in this scenario, a drainage pipe is provided on the collection tank. When in use, the liquid in the collection tank is extracted through the drainage pipe.

[0059] In one embodiment, the collection platform 6 can be connected to the end of the frame 21 away from the fixing ring 1 via a connecting piece 7. The connecting piece 7 is connected to the collection tank, and its side close to the frame 21 is connected to the upper end of the inclined section 211. The connecting piece 7 divides the collection tank into a first groove 61 and a second groove 62, and the first groove 61 and the second groove 62 are respectively located outside the inclined section 211 and the inclined surface 214.

[0060] Optionally, the inner diameter of the collecting table 6 is smaller than the inner diameter of the gripping portion.

[0061] Optionally, the length of the connecting piece 7 is adapted to the length of the collecting tank, and the connecting piece 7 divides the collecting tank into two connected first grooves 61 and second grooves 62. Optionally, a plurality of through holes are opened on the connecting piece 7, and the first groove 61 and the second groove 62 are connected through the through holes.

[0062] In one embodiment, a guide groove 215 is provided on the inner wall of the skeleton 21 from one end close to the fixing ring 1 to the inclined surface 214, and guide rods 216 are provided on the inner wall of the skeleton 21 on both sides of the guide groove 215. Optionally, the guide rods 216 are arranged at an angle. During the use of the dilator, part of the liquid produced by the patient can flow into the guide groove 215 along the guide rods 216. Since the inclined surface 214 is inclined outward from one end of the guide groove 215 to the collection groove, the liquid in the guide groove 215 flows into the collection groove to further improve the liquid collection effect.

[0063] It should be noted that in the drawings, the specific sizes (length, thickness, etc.) of the fixing ring 1 and the skeleton 21 are schematic and are only used to express the concept of the present technical solution, and do not involve any limitation on the specific sizes in actual embodiments.

[0064] Parts not described in detail in this embodiment are well-known technologies in the art.

[0065] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention.
