Description

Technical Field

[0001] The utility model relates to the technical field of vaginal dilators, in particular to a sterile vaginal dilator. Background Art

[0002] Vaginal dilators are often used during gynecological examinations. Vaginal dilators are generally composed of duckbill upper and lower blades. When used, the closed upper and lower blades are placed in the vagina at the same time, and then the upper and lower blades are separated by an adjustment device to open the patient's vagina and expose the patient's uterus. However, existing dilators are not very friendly when used on patients with hypertrophic labia, which may cause pain or discomfort in the patient's labia. Therefore, we propose a sterile vaginal dilator. Utility Model Content

[0003] The purpose of the utility model is to propose a sterile vaginal dilator in view of the problems existing in the background technology.

[0004] The technical solution of the utility model: a sterile vaginal dilator, comprising a dilator body consisting of an upper blade and a lower blade, the upper blade being a dilator portion, the upper blade and the lower blade being both divided into an upper use portion and a lower gripping portion, the use portion of the upper blade being divided into an upper bulge, an upper labia opening and an upper contact head starting from entering the patient's vagina, the upper bulge being an arc-shaped bulge, the upper labia opening being an arc-shaped depression, and the upper contact head being an arc-shaped protrusion, the use portion of the lower blade being divided into a lower bulge and a lower labia opening starting from entering the patient's vagina, the lower labia opening being located between the use portion and the gripping portion of the lower blade, the gripping portion of the lower blade including a lower contact head, the lower bulge being an arc-shaped bulge, the lower labia opening being an arc-shaped depression, and the lower contact head being an arc-shaped protrusion.

[0005] Preferably, the arc-shaped protrusion angle of the lower blade is smaller than the arc-shaped protrusion angle of the upper protrusion, and the arc-shaped depression angle of the upper labia opening is larger than the arc-shaped depression angle of the lower labia opening.

[0006] Preferably, an upper force-reinforcing portion is located between the upper labia opening and the upper contact head, and a lower force-reinforcing portion is located between the lower labia opening and the lower contact head.

[0007] Preferably, connecting plates are installed on both sides of the lower blade, the upper blade is installed between the two connecting plates, and a connecting rod is provided between the two connecting plates and the upper blade.

[0008] Preferably, a spring is installed between the gripping parts of the upper blade and the lower blade.

[0009] Preferably, an insertion rod is fixedly mounted on the end of the gripping portion of the upper blade, a fixing plate is rotatably mounted on the insertion rod, and a fixing groove is correspondingly provided on the gripping portion of the lower blade.

[0010] Compared with the existing technology, the beneficial effect of the utility model is: in this scheme, when the upper blade and the lower blade enter the patient's vagina, the lower blade and the upper bulge are arc-shaped and can stretch the vagina. At this time, the patient's labia will also be stretched. For patients with larger labia, the labia will feel obvious discomfort when being stretched. As the upper blade and the lower blade continue to enter, the labia will enter the upper labia opening and the lower labia opening, and the angle of the labia being stretched will be alleviated, especially the labia inside the upper labia opening. Because the upper blade is the expansion part of the dilator, the feeling of the labia inside the upper labia opening is more obvious. The labia wall is in contact with the upper contact head and the lower contact head to prevent the dilator from being blocked by excessively large or thick labia, thereby obstructing the line of sight. Therefore, this arrangement can alleviate the discomfort of patients with excessively large and thick labia, and reduce the resistance to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Embodiment 1

[0015] See attached Figure 1The aseptic vaginal dilator comprises a dilator body consisting of an upper blade 1 and a lower blade 2, wherein the upper blade 1 is a dilator portion, and the upper blade 1 and the lower blade 2 are both divided into an upper use portion and a lower gripping portion, and the use portion of the upper blade 1 is divided into an upper ridge 3, an upper labia orifice 4 and an upper contact head 5 from the time of entering the patient's vagina, the upper ridge 3 is an arc-shaped ridge, the upper labia orifice 4 is an arc-shaped depression, and the upper contact head 5 is an arc-shaped convexity, and the use portion of the lower blade 2 is divided into a lower ridge 7 and a lower labia orifice 8 from the time of entering the patient's vagina, and the lower labia orifice 8 is located between the use portion and the gripping portion of the lower blade 2, and the lower blade 2 is provided with a plurality of protruding protrusions, wherein the protruding protrusions are ... The gripping portion includes a lower contact head 9, a lower raised portion 7 is an arc-shaped raised portion, a lower labia opening 8 is an arc-shaped recessed portion, and a lower contact head 9 is an arc-shaped convex portion. Through this arrangement, when the upper blade 1 and the lower blade 2 enter the patient's vagina during use, the lower blade 2 and the upper raised portion 3 can stretch the vagina because of the arc-shaped raised portion. At this time, the patient's labia will also be stretched. For patients with larger labia, the stretched labia will obviously feel uncomfortable. As the upper blade 1 and the lower blade 2 continue to enter, the labia will enter the upper labia opening 4 and the lower labia opening 8, and the angle of the stretched labia will be alleviated. Especially the labia inside the upper labia opening 4, because the upper blade 1 is the expansion part of the dilator, the labia inside the upper labia opening 4 feels relieved more obviously, and the labia wall is in contact with the upper contact head 5 and the lower contact head 9 to prevent the dilator from being blocked by the labia being too large or too thick, thereby obstructing the line of sight. Therefore, this arrangement can relieve the discomfort of patients with too large and thick labia, and reduce the resistance to use. The arc bulge angle of the lower blade 2 is smaller than the arc bulge angle of the upper bulge 3, and the arc concave angle of the upper labia opening 4 is larger than the arc concave angle of the lower labia opening 8. Because the upper blade 1 is the expansion part of the expander, so the lower blade 2 moves during expansion, so the expansion and squeezing force on the labia is greater, and the discomfort is more obvious. Therefore, the large angle of the upper bulge 3 is to make the expansion more obvious, and the large angle of the upper labia opening 4 is to more effectively relieve the discomfort after the labia enters. The upper force part 6 is between the upper labia opening 4 and the upper contact head 5, and the lower force part 10 is between the lower labia opening 8 and the lower contact head 9. In use, the upper force part 6 and the lower force part 10 are both force support points of the labia. In order to avoid excessive friction, these places are coated with lubricating oil in advance. Embodiment 2

[0016] See attached Figure 1 and 2Based on the first embodiment, connecting pieces 12 are installed on both sides of the lower blade 2, the upper blade 1 is installed between the two connecting pieces 12, a connecting rod 13 is provided between the two connecting pieces 12 and the upper blade 1, a spring 14 is installed between the gripping parts of the upper blade 1 and the lower blade 2, an insertion rod 15 is fixedly installed at the end of the gripping part of the upper blade 1, a fixing plate 16 is rotatably installed on the insertion rod 15, and a fixing groove 17 is correspondingly opened on the gripping part of the lower blade 2. When in use, the use part of the upper blade 1 is expanded by pressing the gripping part of the upper blade 1, and the upper blade 1 will rotate with the support of the connecting rod 13. At this time, the spring 14 will contract, and then the insertion rod 15 and the fixing groove 17 will pass through the fixing plate 16. When the expansion angle needs to be fixed, the fixing groove 17 is rotated to make it contact with the lower blade 2. At this time, the fixing groove 17 will not come out of the fixing plate 16, and the expansion angle is fixed.
