[0001] The utility model relates to the field of medical instruments, in particular to a negative pressure nipple retraction correction device. Background Art

[0002] The nipple cannot protrude but is sunken inward, which is called inverted nipple or nipple depression. According to the depth of nipple inversion, it can be classified into first degree, second degree and third degree. The first and second degrees can be corrected by pulling the nipple. The negative pressure suction method can be used to pull the inverted nipple by vacuuming for correction.

[0044] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment 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.

[0045] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "vertical", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying 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 orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0046] In the description of the present utility model, "first feature" and "second feature" may include one or more of the features. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0047] The utility model is further described below in conjunction with the accompanying drawings.

[0048] Example 1: Reference Figure 1 and Fig.11 The negative pressure nipple inverted correction device shown in the figure comprises an auxiliary bra 1 and a negative pressure correction mechanism 2; the negative pressure correction mechanism 2 comprises a correction suction cup 21 and a negative pressure control mechanism; the correction suction cup 21 comprises a suction cup cover 211, and a skirt 212 extends outward from the lower edge of the suction cup cover 211; specifically, the correction suction cup 21 is made of silicone material. More specifically, it can be made of transparent silicone material to facilitate observation of the negative pressure pulling situation.

[0049] The correction suction cup 21 is provided with a connecting trachea 3, one end of which is detachably connected to the negative pressure control structure; the auxiliary wearing bra 1 includes cups 11 corresponding to the left chest and the right chest respectively, and the peak position of the cup 11 is provided with a limiting perforation 111 that cooperates with the correction suction cup 21, and the diameter of the limiting perforation 111 is greater than or equal to the diameter of the suction cup cover 211. It is well known in the art that the peak point of the cup is the highest point of the cup, which corresponds to the position of the nipple. The utility model uses the correction suction cup 21 to perform vacuum negative pressure traction on the nipple to correct the nipple, which is an existing conventional technology, and its principle will not be repeated here.

[0050] The diameter of the limiting through-hole 111 in the present embodiment is smaller than the outer diameter of the skirt 212, so that the correction suction cup 21 of the suction cup cover 211 passing through the limiting through-hole can be fixed by wearing the bra. As is known, the bra comprises shoulder straps 13, a back ratio, a heart portion 12, and a lower circumference portion 14. The ends of the back ratio are respectively connected with a row of buckles and corresponding hooks. The back ratio is mostly made of elastic fabric. The shoulder straps 13 are provided with an adjusting buckle, and the adjusting buckle can adjust the length of the shoulder straps. The adjusting buckle can adopt an 8-shaped buckle. During the wearing of the bra, the length of the shoulder straps can be adjusted and the row of buckles of the back ratio can be adjusted so that the cup can be worn fitly with the chest. Therefore, in the actual application of the present embodiment, the size of the bra, such as the size of the cup, can be adapted and selected according to the actual needs of the user. Specifically, different types of bras can be prepared according to the cup size to adapt to different groups of people. This is common knowledge. When the cup of this embodiment fits the chest, the cup around the limiting perforation has a certain pressing force on the skirt, so that the suction cup cover 211 passes through the limiting perforation corresponding to the cup and cooperates with the wearing of the bra to limit and fix the correction suction cup. When the vacuum is drawn through the syringe, there is no need to continue to hold it by hand. There may be another embodiment, wherein the auxiliary wearing bra is preferably a one-piece type. Of course, other types of bras can also be used. And the circumference of the limiting perforation 111 has a sealing edge 112.

[0051] The negative pressure control mechanism includes a three-way pipe 23 and a syringe 110. The connecting air pipe 3 is detachably connected to the branch pipe 222 of the three-way pipe 22 through a first connector 4, and the syringe 110 is detachably connected to the main pipe 221 of the three-way pipe 22 through a second connector 6. In the specific embodiment, the three-way pipe 23 can be a Y-type three-way or a T-type three-way (as shown in the drawings of this embodiment), and preferably, the Y-type three-way is selected. The branch pipe 222 of the three-way pipe 22 connected to the connecting air pipe 3 on the left is provided with a first cut-off control member 9, and the branch pipe 222 of the three-way pipe 22 connected to the connecting air pipe 3 on the right is provided with a second cut-off control member 100. The first cut-off control member 9 and the second cut-off control member 100 are selected from Robert stop-flow clamps or PVC ball valves. The Robert stop-flow clamp is a component commonly used in medicine to clamp a hose and cut off the flow of fluid in the hose. This structure and its working principle will not be described in detail. The structure, use and principle of the ball valve are all conventional technologies and will not be described in detail here. Preferably, the present embodiment uses Robert's stop clamp, which can be adjusted along the branch pipe and is more flexible to use. In specific implementation, the first cut-off control member 9 and the second cut-off control member 100 can be used to cut off the branch pipe, so that the nipple on one side can be vacuumed for negative pressure traction correction, and the nipples on both sides can be vacuumed for negative pressure traction correction at the same time, for example Figure 4As shown, after the suction cup cover 211 passes through the limiting perforation and is connected to the negative pressure control mechanism through the first connector, the auxiliary wearing bra 1 is put on, and the cup is made to fit the chest by adjusting the shoulder straps and the row of buckles, and then the suction cup cover 211 is slightly adjusted to make it better correspond to the nipple position. At this time, the cup can play a certain role in limiting and fixing the correction suction cup 2 by pressing the skirt edge, and the skirt edge is made to fit the skin without hand support, and then only the left correction suction cup 21 needs to be vacuumed. When the first cut-off control member 9 is controlled to be in a loose (open) state, the second cut-off control member 100 is clamped (closed), and then the syringe is connected through the second connector, and the piston is gently pulled outward, so that only the correction sucker 21 on the left side can be vacuumed. When bilateral nipple correction is required, the first cut-off control member 9 and the second cut-off control member 10 are controlled to be in a loose (open) state, and then the syringe is connected through the second connector, and the piston is gently pulled outward, so that only the correction sucker 21 on the left and right sides can be vacuumed. And during use, after the correction sucker 21 pulls the nipple by vacuuming, after the skirt is adsorbed on the skin, the first cut-off control member 9 and the second cut-off control member 10 can be controlled to be clamped (closed), and the syringe can be separated from the second connector, so that the influence of the vertical pulling force of the syringe can be reduced during the negative pressure holding time. There can also be other embodiments, for example, the main pipe is provided with a third cut-off control member to achieve double cut-off.

[0052] Specific as Figures 6 to 9 As shown, the first connector 4 includes a first connecting tube 41 fixedly connected to the connecting air pipe 3, the tube cavity of the first connecting tube 41 is communicated with the connecting air pipe 3, and the branch tube 222 is inserted and clamped in the tube cavity of the first connecting tube 41. More specifically, the branch tube 222 and the tube cavity of the first connecting tube 41 are interference fit, that is, the outer diameter of the branch tube is slightly larger than the diameter of the tube cavity of the first connecting tube 41 to ensure its sealing.

[0053] There may be another embodiment, wherein the branch pipe 222 is a hose, and its end is a hard pipe section, for example, made of PVC plastic, and the end of the hard pipe section is tapered to facilitate insertion into the barrel cavity of the first connecting barrel 41. The branch pipe hard pipe and the hose can be connected by hot welding. The hose can be made of PP or PE; the first connecting barrel 41 can be made of PVC or hard rubber.

[0054] Furthermore, there may be another embodiment, wherein the first connector 4 also includes a second connecting tube 42, and the second connecting tube 42 is slidably connected to the branch pipe 222; a groove 43 is provided on the hard pipe section of the branch pipe, and the second connecting tube 42 is sleeved on the branch pipe corresponding to the groove. The second connecting tube may be made of PVC material or hard rubber material. A second external thread is provided on the outer wall of the first connecting tube 41, and a second internal thread matching the second external thread is provided on the inner wall of the second connecting tube 41. The second connecting tube 41 is connected to the first connecting tube by screwing, which can further increase the firmness of the connection between the air pipe and the three-way pipe, and can avoid problems such as detachment caused by pulling;

[0055] In another embodiment, the connecting air pipe is a hose, so that the suction cup cover 211 can be more easily passed through the limit perforation by deforming the connecting air pipe. The connecting air pipe can be made of rubber or PP or PE. More specifically, the outer diameter of the first connecting tube is larger than the outer diameter of the connecting air pipe, and the connecting hose is upward ( Figure 3 After the first connecting tube is deformed (in the orientation shown in the figure), the first connecting tube extends beyond the top of the suction cup cover 211 to ensure that the suction cup cover 211 passes through the limiting perforation. For example, when passing the suction cup cover through the limiting perforation, by deforming the connecting hose upward so that the first connecting tube is vertically parallel to the suction cup cover 211, the first connecting tube first passes through the limiting perforation, and then the suction cup cover 211 passes through the limiting perforation. Of course, the deformation ability of the suction cup cover 211 can also be used in combination with a deformable hose to allow the suction cup cover 211 to pass through the limiting perforation. Alternatively, the diameter of the suction cup cover 211 changes from top to bottom, and the sum of the diameter of the connecting air pipe and the first connecting tube plus the diameter corresponding to its installation position is less than the diameter of the limiting perforation, thereby ensuring that the suction cup cover 211 can easily pass through the limiting perforation.

[0056] Specific as Fig. 9 and Fig.11As shown, a deflation assembly 5 is provided on the main pipe 221 of the three-way pipe 23. The deflation assembly 5 includes a deflation pipe 52 connected to the three-way pipe, a sealing rod 53 is sleeved in the tube cavity of the deflation pipe 52, and a control cap 51 is provided on the sealing rod 53. A deflation through hole 521 is provided at a position close to the port of the deflation pipe 52; a first internal thread 522 is provided on the inner wall of the tube cavity of the deflation pipe 52 at the upper and lower positions of the deflation hole 521; and a first external thread matching the first internal thread 522 is provided on the sealing rod 53. When in use, when the sealing rod is screwed out of the tube cavity of the deflation pipe 52, when the end of the sealing rod away from the control cap 51 is screwed out to the deflation through hole 521, the deflation pipe 52 is deflated through the deflation through hole and communicated with the atmosphere, so that the correction suction cup 21 can be easily separated from the skin, thereby increasing the convenience of operation. Furthermore, through the threads on both sides of the deflation through hole 521, deflation can be achieved through the deflation hole without completely separating the sealing rod from the tube cavity of the deflation tube, thereby avoiding the loss of the sealing rod.

[0057] A one-way valve 7 is provided on the main pipe, and the one-way valve is located between the deflation component and the second connector to ensure that the deflation component is deflated.

[0058] like Figure 4 As shown, the second connector includes a third connecting tube connected to the main tube 221, and the third connecting tube is detachably connected to the nipple of the syringe. For example, the third connecting tube can adopt a conventional structure (such as Figure 6 ) and the nipple of the syringe (as shown Figure 5 The third connecting cylinder and the nipple of the syringe are detachably connected by snap-fitting. Specifically, a connecting cylinder is provided in the third connecting cylinder, and the cylinder cavity of the connecting cylinder is connected to the cylinder cavity of the main pipe. The outer cylinder of the nipple of the syringe is sleeved in the cylinder cavity of the third connecting cylinder, and the inner cylinder of the nipple of the syringe is sleeved on the outside of the connecting cylinder. The following structure can also be used to realize the detachable connection between the third connecting cylinder and the nipple of the syringe. The cylinder cavity of the third connecting cylinder is connected to the cylinder cavity of the main pipe, and the inner wall of the cylinder cavity of the third connecting cylinder is provided with a third internal thread, and the outer cylinder of the nipple of the syringe is provided with a fourth internal thread that cooperates with the third internal thread. More specifically, the structure of the syringe is a conventional structure, so it will not be described in detail here.

[0059] Example 2: Reference Figure 1 and Fig.12 A negative pressure nipple correction device is shown in FIG. 1 . Compared with Example 1, this embodiment is specifically as follows Fig.12As shown, a vertical first fixing belt 17 is provided on the side of the cup 11 facing away from the human body; more specifically, the lower end of the first fixing belt 17 is fixed to the cup 11 by sewing, and a first Velcro is provided on the belt body, and a second Velcro is provided on the cup to cooperate with the first Velcro, so that the branch pipes of the three-way pipe can be fixed and limited by the first fixing belt, and can also play a certain load-bearing role, reducing the pulling of the three-way pipe and its branch pipes on the correction sucker 21, so as to better limit and fix the correction sucker 21. One or more first fixing belts can be provided on a cup.

[0060] More specifically, the connecting air pipe is a hose, so that the suction cup cover 211 can be more easily passed through the limiting perforation through the deformation of the connecting air pipe. More specifically, the connecting air pipe is as close to the skirt as possible to facilitate the use of a fixing belt to limit and fix the three-way pipe after connection.

[0061] Example 3: Reference Figure 1 and Fig.12 The negative pressure nipple inverted correction device shown in the embodiment is compared with the embodiment 2. The second fixing belt 15 is provided on the heart portion 12 and the lower circumference portion 14. The second fixing belt 15 is horizontal and preferably located in the middle of the two cups. One side of the second fixing belt is fixed to the auxiliary wearing bra 1 by sewing thread. The belt body of the second fixing belt 15 is provided with a third Velcro. The auxiliary wearing bra 1 is provided with a fourth Velcro that cooperates with the third Velcro. The second fixing belt is mainly used to limit and fix the main pipe of the three-way pipe to avoid drooping and causing discomfort. Furthermore, the lower circumference has a certain upper and lower width. Preferably, there may be another embodiment. After the negative pressure control mechanism is connected to the correction suction cup respectively through the first joint, the second connection joint does not exceed the lower circumference downward to reduce the discomfort caused by skin contact therewith.

[0062] Example 4: Reference Figure 1 and Fig.16 A negative pressure nipple retraction correction device as shown in Figure 15 to Figure 16 As shown, compared with any one of the embodiments 1 to 3, the diameter of the limiting through hole 111 in this embodiment is larger than the diameter of the suction cup cover 211, the skirt is detachably connected with an auxiliary fixing ring 8, the diameter of the center ring of the auxiliary fixing ring 8 is larger than the diameter of the suction cup cover 211 and smaller than the diameter of the skirt 212; the diameter of the auxiliary fixing ring 8 is larger than the diameter of the limiting through hole 111;

[0063] Specifically, a limiting clamping column 213 is provided on the side of the skirt facing away from the human body, and a limiting clamping hole 81 is provided on the ring plate of the limiting fixing ring 8 for matching with the limiting clamping column 213. Fig.13As shown, a mesh bag 16 is provided on the side of the cup facing the human body, and the mesh bag 16 and the cup are enclosed to form a mesh bag. A through hole is provided on the mesh bag 16, and the diameter of the through hole is adapted to the skirt, that is, the through hole can allow the skirt to pass through, and the diameter of the through hole is smaller than the diameter of the auxiliary fixing ring 8. It is known that the skirt of the correction sucker 21 corresponds to the areola position, and its diameter is limited. In this embodiment, the outer diameter of the auxiliary fixing ring 8 is larger than the skirt, and the skirt is clamped on the auxiliary fixing ring 8 through a limiting clamping column and a limiting clamping hole 81, so that the cup covering area can be expanded, and the limiting fixation of the correction sucker 21 can be further increased. The material of the auxiliary fixing ring 8 is consistent with that of the skirt, and both can be made of deformable silicone material, which can be deformed and fit the chest with the covering pressure of the cup. Further, it can be made of transparent silicone material to facilitate observation of the skirt. The mesh bag is made of elastic fabric.

[0064] There may be other embodiments, and the diameter of the limiting perforation may be set larger, even larger than the diameter of the skirt, so that not only the correction suction cup 21 is limited and fixed by the cup covering the auxiliary fixing ring 8, but also the position of the auxiliary fixing ring 8 can be better adjusted so that the correction suction cup 21 can better correspond to the nipple position, so as to achieve negative pressure traction on the nipple by vacuuming.

[0065] During the specific implementation of this embodiment, after the suction cup cover passes through the central ring of the auxiliary fixing ring 8, the limiting clamping column 213 is then correspondingly engaged with the limiting clamping hole 81, and the suction cup 213 is placed in the mesh bag. Then, the skirt is passed through the through hole, and the suction cup cover 211 is passed through the limiting through hole 111. Then, the negative pressure control structure is connected through the first connector. After the auxiliary bra 1 is put on and the cup fits the chest, the corresponding correction suction cup 21 is adjusted so that the suction cup cover 211 is as centered as possible against the nipple.

[0066] Example 5: Reference Figure 1 and Fig.11 , Fig.17 A negative pressure nipple inverted correction device is shown. Compared with Example 1, this embodiment has a deflation component on the hose corresponding to the suction cup cover 211 connected to the left or right side, and the deflation component is respectively arranged between the second connecting cylinder and the first cut-off control component 9, and the second connecting cylinder and the first cut-off control component 10. In this way, the vacuum negative pressure of the suction cup cover 211 corresponding to the left chest or the right chest can be controlled separately by the deflation component, and the vacuum negative pressure of the two suction cup covers 211 can be controlled simultaneously by the deflation component located in the main pipe, so as to increase the flexibility of use.

[0067] Example 6: Reference Figure 1 and Fig.11A negative pressure nipple retraction correction device is shown. Compared with Example 1, this embodiment has a rubber sealing pad on the left side wall or the right side wall of the groove. For example, the rubber sealing pad is attached to the left side wall or the right side wall of the groove using an adhesive. When the second connecting tube slides until it fits with the groove and pressure is applied to the rubber sealing pad, the sealing effect can be further enhanced.

[0068] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
