[0032] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] like Figure 2-Figure 6 As shown, the utility model provides an anti-scratch vaginal dilator, comprising an expansion sheet upper page 2, an expansion sheet lower page 1, a handle 3 and a lubricating sleeve, the second end of the expansion sheet lower page 1 is connected to one end of the handle 3, the first end of the expansion sheet lower page 1 extends in a first direction, the second end of the expansion sheet upper page 2 is hinged to the second end of the expansion sheet lower page 1, and the first end of the expansion sheet upper page 2 extends in the first direction;

[0034] The lubricating sleeve wraps around the outer circumference of the upper page 2 of the expansion sheet and the outer circumference of the lower page 1 of the expansion sheet;

[0035] The lubricating sleeve comprises an upper sleeve body 6 and a lower sleeve body 7 which are completely identical and independent of each other. A first containing bag 603 is arranged inside the upper sleeve body 6 and the lower sleeve body 7. The first containing bag 603 is filled with lubricating liquid. A plurality of first liquid outlet holes 601 are arranged on the outer surfaces of the upper sleeve body 6 and the lower sleeve body 7. A piercing mechanism 8 for piercing the first containing bag 603 is installed on the upper sleeve body 6 and the lower sleeve body 7.

[0036] Alternatively, the lubricating sleeve is an integrated structure, a second containing bag 604 is provided inside the lubricating sleeve, the second containing bag 604 is filled with lubricating liquid, a plurality of second liquid outlet holes 606 are provided on the inner wall of the integrated lubricating sleeve, and a puncturing mechanism 8 for puncturing the second containing bag 604 is installed on the integrated lubricating sleeve.

[0037] In this embodiment, the lubricating sleeve is divided into two types. The first type of lubricating sleeve is a split structure, which is composed of an upper sleeve body 6 and a lower sleeve body 7. Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the upper sleeve 6 is bonded to the outer peripheral surface of the right end of the upper page 2 of the expansion sheet, and the lower sleeve 7 is bonded to the outer peripheral surface of the right end of the lower page 1 of the expansion sheet. A first receiving bag 603 is provided inside the upper sleeve 6 and the lower sleeve 7. The first receiving bag 603 is filled with lubricating liquid. A plurality of first liquid outlet holes 601 are provided on the outer surfaces of the upper sleeve 6 and the lower sleeve 7, and a puncturing mechanism 8 for puncturing the first receiving bag 603 is installed on the upper sleeve 6 and the lower sleeve 7.

[0038] The first receiving bag 603 in the upper sleeve 6 and the lower sleeve 7 is pierced by the piercing mechanism 8, and the lubricating liquid in the first receiving bag 603 flows into the upper sleeve 6 and the lower sleeve 7. Then the medical staff squeezes the upper sleeve 6 and the lower sleeve 7, so that the lubricating liquid flows out from the first liquid outlet 601 and is evenly distributed on the outer peripheral surface of the upper sleeve 6 and the lower sleeve 7. In this way, there is no need to manually use a cotton swab or a cotton ball to dip the lubricating liquid and apply it to the vaginal dilator, which is simple to operate, saves time and effort. In addition, since the upper and lower pages 2 and 1 of the dilator are respectively wrapped by the upper and lower sleeves 6 and 7, the inner wall of the patient's vagina can be prevented from being scratched.

[0039] The second lubrication sleeve is Figure 7 and Figure 8 As shown, the lubricating sleeve is an integrated structure, in which a second containing bag 604 is arranged in the internal cavity of the lubricating sleeve, the second containing bag 604 is filled with lubricating liquid, a plurality of second liquid outlet holes 606 are arranged on the inner wall of the integrated lubricating sleeve, and a puncturing mechanism 8 for puncturing the second containing bag 604 is installed on the integrated lubricating sleeve.

[0040] In this way, the lubricating sleeve can be directly put on the vaginal dilator to wrap the upper dilator page 2 and the lower dilator page 1, and then the second receiving bag 604 inside the lubricating sleeve is punctured by the puncturing mechanism 8, and the lubricating liquid inside the second receiving bag 604 is evenly spread on the outer circumference of the upper dilator page 2 and the lower dilator page 1 from the second liquid outlet 606 on the inner wall of the integrated lubricating sleeve. There is no need to manually use a cotton swab or cotton ball to dip the lubricating liquid and apply it on the vaginal dilator, which is simple to operate, saving time and effort.

[0041] Embodiment 1:

[0042] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment 1 provides an anti-scratch vaginal dilator.

[0043] The lubricating sleeve comprises an upper sleeve body 6 and a lower sleeve body 7 which are completely identical. The upper sleeve body 6 is fitted to the outer peripheral surface of the first end of the upper page 2 of the expansion sheet to wrap the outer peripheral surface of the first end of the upper page 2 of the expansion sheet, and the lower sleeve body 7 is fitted to the outer peripheral surface of the first end of the lower page 1 of the expansion sheet to wrap the outer peripheral surface of the first end of the lower page 1 of the expansion sheet; the upper sleeve body 6 has a semi-annular cavity 602 inside, and a plurality of first liquid outlet holes 601 connected to the semi-annular cavity 602 are provided on the outer peripheral surface of the upper sleeve body 6, and a first receiving bag 603 is provided in the semi-annular cavity 602, and the first receiving bag 603 is filled with lubricating liquid, and the first receiving bag 603 is located on the side of the semi-annular cavity 602 close to the second end of the upper page 2 of the expansion sheet; a puncturing mechanism 8 is installed on the side of the upper sleeve body 6 close to the second end of the upper page 2 of the expansion sheet, and the puncturing mechanism 8 is used to puncture the first receiving bag 603.

[0044] It should be noted that if Figure 2 As shown, the upper sleeve 6 is bonded to the outer surface of the right end of the upper page 2 of the expansion sheet, and the lower sleeve 7 is bonded to the outer surface of the right end of the lower page 1 of the expansion sheet. The upper sleeve 6 is attached to the outer surface of the right end of the upper page 2 of the expansion sheet. Figure 2 shown.

[0045] Moreover, the lower surface of the upper sleeve 6 is lower than the lower surface of the right end of the upper page 2 of the expansion sheet, and the upper surface of the lower sleeve 7 is higher than the upper surface of the right end of the lower page 1 of the expansion sheet. In this way, the bottom of the upper sleeve 6 will block the edge of the upper page 2 of the expansion sheet, and the top of the lower sleeve 7 will block the edge of the lower page 1 of the expansion sheet.

[0046] When the upper page 2 of the expansion sheet and the lower page 1 of the expansion sheet are in a fitted state, the lower surface of the upper sleeve body 6 and the upper surface of the lower sleeve body 7 are in a tightly squeezed state.

[0047] The disposable vaginal dilator has relatively sharp edges of the upper and lower pages 2 and 1 of the expansion sheet, and the smoothness of the surfaces of the upper and lower pages 2 and 1 of the expansion sheet is limited. When in use, the edges and surfaces of the upper and lower pages 2 and 1 of the expansion sheet are easy to scratch the patient's vagina. In this embodiment, by bonding the upper sleeve 6 and the lower sleeve 7 on the outer circumference of the upper and lower pages 1 of the expansion sheet, the upper sleeve 6 and the lower sleeve 7 wrap the outer circumference of the upper and lower pages 1 of the expansion sheet, so that the surfaces of the upper and lower pages 2 and 1 of the expansion sheet will not scratch the inner wall of the patient's vagina. In addition, because the bottom of the upper sleeve 6 blocks the edge of the upper and lower pages 2 of the expansion sheet, and the top of the lower sleeve 7 blocks the edge of the lower page 1 of the expansion sheet, the edges of the upper and lower pages 2 and 1 of the expansion sheet will not scratch the inner wall of the patient's vagina.

[0048] As a preferred embodiment, Figure 4 and Figure 5 As shown, a semi-circular cavity 602 is provided in the upper casing body 6, and the cross section of the semi-circular cavity 602 is arc-shaped. A plurality of first liquid outlet holes 601 are evenly provided on the outer wall of the upper casing body 6, and the first liquid outlet holes 601 are connected to the semi-circular cavity 602 inside the upper casing body 6. The puncture mechanism 8 is as shown in FIG. Figure 6 As shown, it comprises a tube body 801, a lower plate 802, a plurality of puncture needles 803 and a connecting rod 804. A circular hole is provided on the outer wall of the left end of the upper sleeve body 6. The tube body 801 is sealed in the circular hole. The lower plate 802 is screwed into the tube body 801. The plurality of puncture needles 803 are provided on the side of the lower plate 802 facing the semi-circular cavity 602. The connecting rod 804 is fixed on the side of the lower plate 802 away from the semi-circular cavity 602. In this way, when puncturing the first receiving bag 603, it is only necessary to rotate the connecting rod 804, and the connecting rod 804 drives the lower plate 802 and the puncture needles 803 to move toward the first receiving bag 603 until the puncture needles 803 puncture the first receiving bag 603. After the first receiving bag 603 is punctured, the lubricating liquid in the first receiving bag 603 is immersed in the semi-annular cavity 602, and then flows out from the first liquid outlet 601 of the semi-annular cavity 602 and is evenly distributed on the outer peripheral surface of the upper sleeve body 6, and the medical staff can use their hands to gently pinch the upper sleeve body 6 to speed up the outflow of the lubricating liquid in the semi-annular cavity 602. In this way, the lubricating liquid can quickly cover the entire outer peripheral surface of the upper sleeve body 6, and the upper sleeve body 6 can play a better lubricating role, without the need to manually use a cotton swab or cotton ball to dip the lubricating liquid and apply it to the vaginal dilator, which is simple to operate, saving time and effort.

[0049] Since the structure of the lower casing 7 is exactly the same as that of the upper casing 6, and the piercing mechanism 8 on the lower casing 7 is exactly the same as that on the upper casing 6, how the piercing mechanism 8 on the lower casing 7 pierces the first containing bag 603 will not be described in detail.

[0050] Further, such as Figure 6 As shown, an internal thread groove is provided on the inner wall of the tube body 801, an external thread matching the internal thread groove is provided on the side of the lower plate 802, a top plate 805 is installed at the end of the connecting rod 804 away from the lower plate 802, the top plate 805 and the lower plate 802 are coaxially arranged, and the outer diameter of the top plate 805 is smaller than the inner diameter of the tube body 801.

[0051] It is worth noting that if Figure 2 As shown, the first accommodation bag 603 in the upper and lower casings 6 and 7 is located at the left ends of the upper and lower casings 6 and 7, and the puncture mechanism 8 is also located at the left ends of the upper and lower casings 6 and 7. Since the insertion depth of the vaginal speculum is generally 10 cm, which is the minimum depth required to expose the cervix, and the distance between the puncture mechanism 8 and the right end of the upper casing 6 in the present application is greater than 10 cm, that is, when in use, the tube 801, the connecting rod 804 and the top sheet 805 in the puncture mechanism 8 are located outside the vagina, which will not scratch the vagina and will not cause inconvenience in use.

[0052] Preferably, the upper sleeve body 6 and the lower sleeve body 7 are both rubber sleeves. The upper sleeve body 6 and the lower sleeve body 7 made of rubber material will not damage the inner wall of the vagina due to their relatively soft material, and are safer to use.

[0053] Optionally, the first containing bag 603 may be a plastic bag or a rubber bag, preferably a rubber bag.

[0054] like Figure 2 As shown, the left end of the expander lower page 1 is fixedly connected to the top of the handle 3, a hinge shaft 4 is installed at the connection between the expander lower page 1 and the handle 3, the left end of the expander upper page 2 and the left end of the expander lower page 1 are hinged through the hinge shaft 4, further, a locking member 5 is installed between the left end of the expander upper page 2 and the handle 3.

[0055] Embodiment 2:

[0056] The second embodiment provides another anti-scratch vaginal dilator. The difference from the first embodiment is that the lubricating sleeve in the second embodiment is detachable, and can apply lubricating liquid to the outer peripheral surface of the dilator upper page 2 and the dilator lower page 1.

[0057] Specifically, Figure 7 and Figure 8 As shown, the lubricating sleeve is a rubber sleeve of an integrated structure, and an annular cavity 605 is provided inside the lubricating sleeve, that is, the cross-section of the lubricating sleeve is annular, and a plurality of second liquid outlet holes 606 are evenly provided on the inner wall of the lubricating sleeve, and an annular second containing bag 604 is arranged inside the annular cavity 605, and a puncturing mechanism 8 is installed on the outer surface of the lubricating sleeve, and the puncturing mechanism 8 is used to puncture the second containing bag 604.

[0058] During specific use, the lubricating sleeve is put on the upper page 2 of the expansion sheet and the lower page 1 of the expansion sheet to wrap the outer circumference of the upper page 2 and the lower page 1 of the expansion sheet, and then the puncturing mechanism 8 is used to puncture the second receiving bag 604, and the lubricating page in the second receiving bag 604 flows out into the annular cavity 605. Then the medical staff can gently pinch the lubricating sleeve to make the lubricating liquid in the annular cavity 605 evenly and fully distributed into the annular cavity 605. The lubricating liquid in the annular cavity 605 is then evenly distributed on the outer circumference of the upper page 2 and the lower page 1 of the expansion sheet from the second liquid outlet 606, so that the lubricating oil is applied to the vaginal dilator. There is no need to manually use a cotton swab or cotton ball to dip the lubricating liquid and apply it to the vaginal dilator. The operation is simple and saves time and effort.

[0059] Compared with the first embodiment, the lubricating sleeve in the second embodiment can be installed on or removed from the vaginal speculum at any time without causing the thickness of the insertion end of the vaginal speculum to become thicker, and it is also convenient to clean the lubricating sleeve.

[0060] It should be noted that the puncturing mechanism 8 is the same as the puncturing mechanism 8 in the above-mentioned embodiment 1, so the puncturing mechanism 8 will not be described in detail.

[0061] In the description of the present invention, it should be noted that the terms "upper" and "lower" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0062] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the insides of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
