Description

Technical Field

[0001] This invention relates to the field of medical auxiliary device technology, and more specifically, to a negative pressure nipple inversion correction device for obstetrics and gynecology. Background Technology

[0002] Because of inverted nipples, the nipples often have to be forcibly pulled out during breastfeeding. At this time, the nipples are very delicate and are easily damaged, cracked and bleeding if bumped, which can cause infection of the nipple and even the entire breast, eventually leading to mastitis.

[0003] Among them, the patent with announcement number CN221490338U discloses a negative pressure nipple retraction correction device, including a cover body, a rubber patch fixedly assembled on the outer edge of the cover body, a round hole opened on the outer edge of the cover body, a threaded fixing tube fixedly assembled on the inner wall of the round hole, a rubber gasket provided at the end of the threaded fixing tube away from the cover body, a vent pipe provided at the end of the rubber gasket away from the threaded fixing tube, and a fixing sleeve threadedly connected to the outer edge of the threaded fixing tube. In use, this structure separates the cover from the ventilation tube by turning the fixed sleeve counterclockwise. After replacing the cover, a rubber gasket is placed inside the fixed sleeve, and then the fixed sleeve is turned clockwise to connect the cover with the ventilation tube and the suction assembly. However, it relies solely on negative pressure suction to pull the nipple without any positioning structure. Because breast tissue is soft and fluid, nipple displacement is prone to occur during negative pressure suction, leading to uncontrollable correction position and an inability to ensure the nipple is always in the optimal correction state, thus affecting the correction effect. Furthermore, the negative pressure cover acts directly on the entire breast surface, easily drawing surrounding normal breast tissue into the cover while suctioning the nipple, affecting the correction effect. Moreover, different users have different nipple indentation depths and breast shapes, making it impossible to precisely adjust the correction force and range according to individual circumstances, resulting in poor correction effects for some users or discomfort due to excessive correction force. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a negative pressure nipple inversion correction device for obstetrics and gynecology, which aims to solve the problems mentioned in the background art.

[0005] This invention provides the following technical solution: a negative pressure nipple inversion correction device for obstetrics and gynecology, comprising a bra body, wherein two correction components are provided on the bra body; The corrective component includes a support pad disposed on one side of the bra body, a breast positioning cover disposed on the support pad, an elastic negative pressure cover disposed on the breast positioning cover, a negative pressure cavity formed between the breast positioning cover and the elastic negative pressure cover, and a one-way valve disposed at one end of the elastic negative pressure cover. The support pad has several sliding grooves through it, and each of the sliding grooves has a slider slidably connected to it. The slider has an integrally formed mounting block. A connecting ring is provided on the side of the slider away from the mounting block, and a correction cone is provided at the bottom of the connecting ring. A protective ring is fitted on one end of the correction cone, and a positioning pressure ball is movably connected inside the protective ring.

[0006] Optionally, in a possible implementation, a mounting cylinder is provided in the middle of the support pad, and a lead screw is movably connected to the mounting cylinder. The end of the lead screw away from the mounting cylinder passes through the breast positioning cover and the elastic negative pressure cover in sequence and extends to one side of the bra body. A support ring is threaded onto the upper part of the lead screw. A plurality of first hinge plates are fixedly provided on the outer side of the support ring, and a hinge rod is hinged to each of the first hinge plates. A second hinge plate is hinged to one end of the hinge rod, and the second hinge plate is fixed to one side of the mounting block. Optionally, in a possible implementation, the vertical cross-sectional shape of both the elastic negative pressure shield and the breast positioning shield is set to an arc shape, and the top of the elastic negative pressure shield is provided with a support plate. The one-way valve is embedded in the support plate and communicates with the negative pressure chamber. A knob is rotatably connected to the support plate. The knob is sleeved on the outside of the lead screw. An adjusting rod is provided on the corrective cone block. The top end of the adjusting rod extends into the mounting block, and a nut for limiting the adjusting rod is embedded in the mounting block. The breast positioning shield and the elastic negative pressure shield are stacked, and the inner wall of the breast positioning shield is provided with a silicone ring. The technical effects and advantages of this invention are as follows: 1. This invention utilizes a linkage mechanism composed of a lead screw, a support ring, and a hinged rod to drive the corrective cones of each positioning pressure ball to move synchronously towards the nipple along the sliding groove, ultimately stabilizing the nipple in a central position through a ring-like enclosure. Compared to existing devices that rely solely on blind suction under negative pressure, this invention effectively avoids nipple displacement during the negative pressure suction process, ensuring that the corrective force always acts on the core area of ​​the nipple, significantly improving the corrective targeting and effectiveness, and is especially suitable for daily correction of patients with mild to moderate nipple inversion.

[0007] 2. During the correction process, the positioning pressure ball uses slight elastic pressure to form a ring-shaped depression in the areola, providing a guiding channel for nipple protrusion; at the same time, the negative pressure adsorption force acts directionally on the nipple. The two work together to accelerate the nipple's protrusion from the depressed state, shorten the time for a single correction to take effect, and long-term use can help the nipple establish a stable protrusion shape and reduce the recurrence rate of depression. 3. The breast positioning cover of this invention is arc-shaped and fits the contour of the breast, exposing only the nipple and areola area. With the sealing effect of the inner silicone ring, the negative pressure of the negative pressure chamber can be strictly limited to the target area, avoiding the problem of mis-adsorption and compression of surrounding tissues caused by the negative pressure acting directly on the entire breast in existing devices. This reduces the risk of obstructed local blood circulation in the breast and prevents swelling, pain and tissue damage caused by long-term wear. 4. This invention uses the adjusting rod at the top of the corrective cone to engage with the nut inside the mounting block via a threaded connection. By rotating the corrective cone, the distance between it and the areola can be adjusted, adapting to different degrees of nipple retraction, such as mild, moderate, and severe. This solves the limitation of existing devices that cannot adapt to individual differences due to their single size. In summary, the corrective cones of each positioning pressure ball move synchronously towards the nipple along the groove, ultimately stabilizing the nipple in a central position through a ring-like enclosure. Compared to existing devices that rely solely on blind suction due to negative pressure, this invention effectively avoids nipple displacement during negative pressure suction, ensuring that the corrective force always acts on the core area of ​​the nipple, significantly improving the targetedness and effectiveness of the correction. It is especially suitable for daily correction of patients with mild to moderate nipple inversion. Furthermore, the distance between the corrective cone and the areola can be adjusted by rotating the corrective cone, adapting to different degrees of nipple inversion, including mild, moderate, and severe cases, thus overcoming the limitation of existing devices that cannot accommodate individual differences due to their single size.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] This embodiment discloses a negative pressure nipple inversion correction device for obstetrics and gynecology, which aims to solve the problems of existing negative pressure nipple inversion correction devices that rely solely on single negative pressure extraction for correction, which cannot accurately locate the nipple, and that the nipple correction position is uncontrollable due to easy adhesion of the breast during the negative pressure extraction process.

[0019] like Figure 1 As shown, the obstetric and gynecological negative pressure nipple inversion correction device mainly includes a bra body 1. The bra body 1 is made of breathable cotton material, and its size can be adjusted according to the chest circumference of different users to ensure the fit and comfort of the device when worn. A correction component is fixedly installed on each side of the bra body 1, corresponding to the breasts. The two correction components have identical structures and can be used to correct the nipples on both sides separately.

[0020] like Figure 3 As shown, the support pad 2 in the corrective component is a circular, thin sheet structure made of medical-grade hard plastic with smoothed edges to avoid scratching the skin. The support pad 2 is fixed to the inside of the bra body 1 by sewing or Velcro, fitting snugly against the outer skin of the breast to provide stable support for the entire corrective component. At the center of the support pad 2, an integrally formed cylindrical mounting tube 14 is provided. The inner wall of the mounting tube 14 has internal threads for connection with the lead screw 15.

[0021] The breast positioning shield 3 is placed over the outside of the support pad 2, such as... Figure 4 As shown, its vertical cross-section is designed with an arc shape to match the natural contour of the breast, providing stable support and preventing displacement during correction. Meanwhile, as... Figure 3 As shown, a silicone ring 22 is fixedly attached to the inner wall of the breast positioning cover 3. The silicone ring 22 is made of medical soft silicone material, which has good elasticity and biocompatibility. When in contact with the skin, it can reduce friction and improve wearing comfort. At the same time, it can also enhance the seal between the breast positioning cover 3 and the skin, providing a guarantee for the subsequent formation of the negative pressure chamber 5.

[0022] like Figure 4 As shown, an elastic negative pressure cover 4 is provided on the outer side of the breast positioning cover 3. The elastic negative pressure cover 4 is made of medical-grade elastic rubber material, and its vertical cross-section is also arc-shaped, and its size is slightly larger than that of the breast positioning cover 3, so that a closed negative pressure chamber 5 is formed between the elastic negative pressure cover 4 and the breast positioning cover 3. A circular support plate is integrally formed on the top of the elastic negative pressure cover 4, and a one-way valve 12 is embedded in the center of the support plate. One end of the one-way valve 12 is connected to the negative pressure chamber 5, and the other end is connected to the outside. The one-way valve 12 only allows outside air to be discharged from the negative pressure chamber 5, while preventing outside air from entering the negative pressure chamber 5. When the elastic negative pressure cover 4 is squeezed, the air in the negative pressure chamber 5 can be discharged through the one-way valve 12. After being released, the elastic negative pressure cover 4 returns to its original shape by its own elasticity, so that a negative pressure is formed in the negative pressure chamber 5, thereby generating an adsorption force on the breast and assisting the nipple to protrude.

[0023] like Figure 3 As shown, several grooves 6 are evenly distributed along the circumference of the support pad 2. In this embodiment, the number of grooves 6 is set to 3, and the length direction of each groove 6 points to the center of the support pad 2. A slider 13 is slidably connected in each groove 6. The shape of the slider 13 is adapted to the groove 6 and can slide freely along the length direction of the groove 6. Figure 6 As shown, a mounting block 7 is integrally formed on the side of the slider 13 near the center of the support pad 2. The mounting block 7 is a square block structure with threaded holes inside.

[0024] like Figure 5As shown, a connecting ring 8 is bolted to the side of the slider 13 away from the mounting block 7. The connecting ring 8 is a circular ring structure. A correction cone 9 is set at the bottom of the connecting ring 8. The correction cone 9 is made of medical-grade hard plastic, and its end away from the connecting ring 8 is a conical structure with a smooth surface to avoid damage to the nipple. A protective ring 10 is fitted on the outside of the conical end of the correction cone 9. The protective ring 10 is made of medical-grade soft silicone material, which can further reduce friction between the correction cone 9 and the nipple and protect the nipple skin. At the same time, a positioning pressure ball 11 is movably connected inside the protective ring 10. The positioning pressure ball 11 is a circular spherical structure made of medical-grade elastic rubber material. When the correction cone 9 approaches the nipple, the positioning pressure ball 11 can contact the areola surface on the outside of the nipple. The slight pressure causes the areola to indent, so that the nipple protrudes and is positioned to ensure that the nipple is in the center of each correction cone 9, achieving precise correction.

[0025] like Figure 5 As shown, one end of the lead screw 15 is movably connected to the mounting cylinder 14, and the other end passes through the through holes opened on the breast positioning cover 3 and the elastic negative pressure cover 4, extending to the outside of the bra body 1. A knob 20 is fixedly installed at the end of the lead screw 15 extending to the outside, such as... Figure 4 As shown, the knob 20 is connected to the lead screw 15 by a thread, and the bottom of the knob 20 is rotatably connected to the support plate on the top of the elastic negative pressure cover 4. When the knob 20 is rotated, the support ring 16 can be moved along the axial direction of the mounting cylinder 14 by the lead screw 15.

[0026] A support ring 16 is fitted on the outer side of the portion of the lead screw 15 located inside the negative pressure chamber 5, such as... Figure 5 As shown, the support ring 16 can move freely along the axis of the lead screw 15, but cannot rotate with the lead screw 15. Several first hinge plates 17 are uniformly fixed along the circumferential direction on the outer side of the support ring 16. The number of first hinge plates 17 corresponds to the number of sliding grooves 6 on the support pad 2; in this embodiment, it is also set to three. Each first hinge plate 17 is hinged to a hinge rod 18 via a pin. The other end of the hinge rod 18 is hinged to a second hinge plate 19 via a pin. The second hinge plate 19 is fixed to the outer wall of the mounting block 7 by bolts. Figure 6 As shown.

[0027] In addition, such as Figure 7As shown, an adjusting rod 21 is integrally formed on the top of the correcting cone block 9. The adjusting rod 21 has an external thread on its outer side. The top of the adjusting rod 21 passes through the connecting ring 8 and extends into the threaded hole opened inside the mounting block 7. A nut that matches the external thread of the adjusting rod 21 is embedded inside the mounting block 7. By rotating the correcting cone block 9, the adjusting rod 21 can be moved in the threaded hole of the mounting block 7, thereby adjusting the distance between the correcting cone block 9 and the mounting block 7, and further adapting to nipples with different degrees of concavity. The specific working principle is as follows: First, the user adjusts the tightness of the shoulder straps and underband by adjusting the buckles on both sides of the bra body 1 according to their own chest circumference, and then wears the bra body 1 smoothly on the chest, ensuring that the two correction components on the inside of the bra body 1 are aligned with the center of the left and right breasts respectively.

[0028] The support pad 2 in the correction component is made of medical-grade rigid plastic with rounded edges to closely conform to the outer skin of the breast. Meanwhile, the silicone ring 22 on the inner wall of the breast positioning cover 3 has good elasticity and biocompatibility, forming a sealed area upon contact with the skin. This avoids friction damage between the support pad 2 and the skin, and also fixes the breast position, preventing breast displacement during correction and laying the foundation for subsequent precise correction. At this time, the breast positioning cover 3 wraps around the breast in an arc shape, exposing only the nipple and surrounding areola area, reducing interference from non-target tissues.

[0029] The user rotates the knob 20 on the outside of the bra body 1. The knob 20 is fixedly connected to the lead screw 15 and rotates in cooperation with the top support plate of the elastic negative pressure cover 4. Rotating the knob 20 can drive the lead screw 15 to rotate stably along the internal thread of the mounting cylinder 14. Since the lead screw 15 and the support ring 16 are threadedly connected, and the support ring 16 is limited by the inner wall of the breast positioning cover 3 and cannot rotate with the lead screw 15, the rotational motion of the lead screw 15 is converted into the linear movement of the support ring 16 along the axis of the lead screw 15.

[0030] Three sets of first hinge plates 17 are evenly distributed on the outer side of the support ring 16. Each set of first hinge plates 17 is hinged to one end of a hinge rod 18 via a pin, and the other end of the hinge rod 18 is hinged to a second hinge plate 19 on the outer side of the mounting block 7. When the support ring 16 moves toward the support pad 2, it applies a pulling force to the mounting block 7 through the hinge rod 18, causing the slider 13, which is integrally formed with the mounting block 7, to slide along the groove 6 on the support pad 2 toward the center of the support pad.

[0031] As slider 13 moves, it simultaneously drives connecting ring 8, corrective cone 9, protective ring 10, and positioning pressure balls 11 toward the nipple. The three sets of positioning pressure balls 11 are circumferentially distributed and eventually contact the areola area on the outer side of the nipple. Through the slight elastic pressure of the medical elastic rubber material, a uniform annular depression is formed in the areola area, stably surrounding the nipple in the center of each positioning pressure ball 11, achieving precise centered positioning of the nipple and preventing nipple displacement during subsequent negative pressure adsorption.

[0032] If the user's nipple indentation is deep, the depth can be adjusted by rotating the corrective cone 9. The adjusting rod 21 at the top of the corrective cone 9 has an external thread on its outer side, which engages with the nut thread in the mounting block 7. When the corrective cone 9 is rotated, the adjusting rod 21 can move axially along the threaded hole, thereby shortening or lengthening the distance between the corrective cone 9 and the areola, ensuring that the positioning pressure ball 11 can effectively contact the outer area of ​​the indented nipple, adapting to different depths of nipple indentation.

[0033] Based on precise nipple positioning, the negative pressure suction force of negative pressure chamber 5 assists in the nipple to protrude from its inverted state, while avoiding the accidental suction of normal breast tissue. When the user gently squeezes the elastic negative pressure cover 4 with their fingers, the volume of the closed negative pressure cavity 5 formed between the elastic negative pressure cover 4 and the breast positioning cover 3 decreases, and the air inside the cavity is quickly discharged through the one-way valve 12. After the elastic negative pressure cover 4 is released, it returns to its original shape by its own elasticity, the volume of the negative pressure cavity 5 increases, and the air pressure inside the cavity is lower than the external atmospheric pressure, forming a stable negative pressure.

[0034] Since the breast positioning shield 3 has isolated non-target breast tissue, the negative pressure only acts on the nipple and the surrounding areola area. Under the action of negative pressure suction, the inverted nipple is pulled outward and gradually protrudes from the mammary duct. At the same time, the positioned nipple is kept in a centered position under the restriction of the 3 sets of positioning pressure balls 11, avoiding nipple displacement due to negative pressure suction and ensuring accurate and controllable correction position.

[0035] The check valve 12 prevents outside air from entering the negative pressure chamber 5 in reverse, ensuring a stable and long-lasting negative pressure state. Even after prolonged wear, the negative pressure value in the negative pressure chamber 5 will not decrease significantly, eliminating the need for frequent squeezing of the elastic negative pressure cover 4 and improving ease of use.

[0036] During the correction process, users can dynamically adjust the negative pressure according to their own feelings, such as nipple traction and comfort. If they feel that the suction is insufficient, they can gently squeeze the elastic negative pressure cover 4 again to add and expel some air to increase the negative pressure. If they feel that the pressure is too strong, they can press the exhaust button of the one-way valve 12 to release a small amount of air in the cavity to reduce the negative pressure, so as to achieve on-demand adjustment and avoid discomfort caused by excessive negative pressure.

[0037] When a single correction is completed or no further correction is needed, press the valve switch of the one-way valve 12. Outside air enters the negative pressure chamber 5 through the one-way valve 12, and the negative pressure in the chamber disappears quickly. Then, the user can easily remove the device by unfastening the adjustment buckle of the bra body 1. The whole process is without any pulling sensation, avoiding secondary damage to the nipples.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
