Description

Technical Field

[0001] This invention relates to the field of nipple inversion correction technology, and particularly to a negative pressure nipple inversion correction device. Background Technology

[0002] Different women often have different nipple shapes. One abnormal nipple shape is inverted nipple, which is usually a physiological defect caused by congenital malformation. Inverted nipples make breastfeeding more difficult, and infants may lack breast milk because they cannot suckle. Therefore, negative pressure suction is used to pull out the nipple for correction.

[0003] A search revealed, for example, patent CN115040302A, which discloses a negative pressure nipple inversion correction device and method for obstetrics and gynecology. The device includes a cylinder with a first one-way valve and a second one-way valve installed at one end and its side, respectively. A suction nozzle is connected to the end of the first one-way valve away from the cylinder, and a collection bottle is threadedly connected to the end of the second one-way valve away from the cylinder. The collection bottle is used to collect the milk suctioned out during the correction process. A suction mechanism is installed inside the cylinder to extract air from the sealed space between the suction nozzle and the patient's chest, creating negative pressure in the suction nozzle. Ultimately, due to the rolling pressure diffusion action of multiple rollers around the patient's chest, the subsequent exposure and correction of the nipple under negative pressure is facilitated, greatly improving the success rate of correction and reducing patient discomfort.

[0004] However, the negative pressure nipple correction device in the aforementioned patent still has the following shortcomings:

[0005] During the use of negative pressure nipple correction devices, when the inverted nipple is lifted by negative pressure, breast milk is easily drawn out along with it, causing contamination of the device's interior. If the device is not cleaned before the next use, and the user uses it without knowing it, it can easily lead to nipple infection, increasing the risk of disease. Therefore, current correction devices lack a structure that allows users to remind them, which is not conducive to reducing the risk of infection for patients. Summary of the Invention

[0006] In view of this, the present invention provides a negative pressure nipple retraction correction device, which has a first control lever and a marker. In use, the nipple needs to be clamped and limited by rotating the first control lever. During the rotation, the marker can leave a mark on the bottom of the fixing ring. Then, by observing whether the mark still exists in the next use, it can be determined whether the device has been disinfected and cleaned, thereby providing an effective reminder and warning to the user.

[0007] This invention provides a negative pressure nipple retraction correction device, specifically comprising: a cylindrical body; the cylindrical body adopts a cylindrical structure, and a through-hole circular groove is formed at the top of the cylindrical body; a cylindrical first slide rod is slidably disposed within the circular groove at the top of the cylindrical body, and a through-hole circular groove is formed at the top of the first slide rod; a first control rod is slidably disposed within the circular groove at the top of the first slide rod; the first control rod adopts an internally hollow cylindrical structure, and a through-hole circular groove is formed in the middle of the top of the first control rod; the interior of the first control rod is filled with harmless pigment; a sealing structure is provided between the first control rod and the first slide rod; the bottom of the first control rod is fixedly connected to... A circular limiting control ring is provided, and the bottom of the limiting control ring has a threaded groove structure; a marker pen is fixedly connected to one side of the bottom end of the first control rod, and the marker pen communicates with the cavity inside the first control rod; a cylindrical second slide rod is slidably arranged in the circular through groove at the top of the first control rod, and a spring is sleeved on the outside of the second slide rod, and a through circular through groove structure is opened at the top of the second slide rod; a cylindrical liquid suction tube is slidably arranged in the circular through groove of the second slide rod; a cylindrical pigment extrusion block is fixedly arranged at the bottom end of the second slide rod, and the outer wall of the pigment extrusion block is in contact with the inner wall of the first control rod, and a through circular through groove structure is opened in the middle of the bottom of the pigment extrusion block.

[0008] Furthermore, a circular piston plate is fixedly installed at the bottom end of the first slide rod, and the outer wall of the piston plate is in contact with the inner wall of the cylinder; a circular ring is fixedly installed at the bottom inner side of the cylinder, two sets of rectangular sliding grooves are opened on the outer side of the fixed ring, and a circular groove is opened at the top of the fixed ring. A limit control ring is rotatably installed in the circular groove at the top of the fixed ring, and the bottom of the fixed ring is in contact with the top of the marker pen; a sliding mounting block is slidably installed in the rectangular sliding groove on the outer side of the fixed ring; and a conical cover is fixedly installed at the bottom of the cylinder.

[0009] Furthermore, a cylindrical second control rod is rotatably disposed within the circular groove of the second slide rod, and a through circular groove is provided at the top of the second control rod; a large gear is fixedly disposed at the bottom of the second control rod.

[0010] Furthermore, two sets of sliding mounting blocks are provided, and both sets of sliding mounting blocks adopt a rectangular block structure. The sliding mounting blocks and the limit control ring are connected by a threaded connection. A cylindrical drive shaft is rotatably mounted on the inner side of the sliding mounting block. A worm gear is fixedly mounted on the outer side of the drive shaft. A worm is rotatably mounted on the inner side of the sliding mounting block, and the worm is meshed with the worm gear. A small gear is mounted on the top of the worm through a key, and the small gear is meshed with a large gear. A cylindrical nipple-shaped stretching friction roller is rotatably mounted on the bottom of the inner end of the sliding mounting block, and the nipple-shaped stretching friction roller is connected to the drive shaft through a conveyor belt.

[0011] Furthermore, a sealing structure is provided between the liquid suction tube and the second control rod; a negative pressure hollow ball is fixedly installed at the top of the liquid suction tube, the negative pressure hollow ball adopts an internally hollow spherical structure, and a one-way valve structure is provided at the connection between the negative pressure hollow ball and the liquid suction tube; a liquid reservoir is connected to the top of the negative pressure hollow ball through a pipe, the liquid reservoir adopts an internally hollow cylindrical structure, and a one-way valve structure is provided at the connection between the liquid reservoir and the negative pressure hollow ball, and an exhaust port structure is provided on the liquid reservoir.

[0012] Beneficial effects

[0013] In this invention, through the cooperation of various components, during the use of the device, a mark can be left on the bottom of the fixing ring with a marker to indicate that the device has been used. During the next use, by observing whether the mark is still there, it can be determined whether the device has been effectively cleaned and disinfected. This allows the user to effectively know the cleaning and disinfection status of the device without knowing it, avoiding the phenomenon of forgetting to clean or missing cleaning, which could lead to bacteria inside the device and cause infection of the user's nipples, thereby improving the safety of the device during use.

[0014] Furthermore, after the nipple is lifted by negative pressure, the positions of the two sets of sliding mounting blocks are adjusted so that the two sets of nipple stretching friction rollers come into contact with both sides of the nipple. The two sets of nipple stretching friction rollers are rotated by rotating the second control lever, and the nipple is stretched outward by the two sets of nipple stretching friction rollers. This allows the nipple stretching friction rollers to work well with the negative pressure generated by the cylinder and cover, greatly improving the effect of nipple correction and avoiding the limitations of correction by simply using negative pressure.

[0015] In addition, if milk leakage occurs from the nipple during the calibration process, the position of the liquid suction tube can be adjusted so that it is aligned with the milk leakage location. The liquid is then suctioned out of the cover through the combination of suction and negative pressure hollow bulb. Compared with the traditional method of natural liquid drainage, this method can improve the speed and effectiveness of liquid cleaning and avoid discomfort caused by prolonged liquid presence.

[0028] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0029] Example 1: Please refer to Figures 1 to 8 :

[0030] This invention proposes a negative pressure nipple retraction correction device, comprising: a cylindrical body 1; the cylindrical body 1 has a cylindrical structure, and a through-hole circular groove structure is provided at the top of the cylindrical body 1; a cylindrical first slide rod 101 is slidably disposed in the circular groove at the top of the cylindrical body 1, and the top of the first slide rod 101 has a through-hole circular groove structure; a first control rod 2 is slidably disposed in the circular groove at the top of the first slide rod 101; the first control rod 2 has a hollow cylindrical structure, and a through-hole circular groove structure is provided in the middle of the top of the first control rod 2; the interior of the first control rod 2 is filled with harmless pigment; a sealing structure is provided between the first control rod 2 and the first slide rod 101; a circular limiting control ring 2 is fixedly connected to the bottom of the first control rod 2. 01, and the bottom of the limit control ring 201 is provided with a threaded groove structure; a marker pen 202 is fixedly connected to one side of the bottom end of the first control rod 2, and the marker pen 202 communicates with the cavity inside the first control rod 2; a cylindrical second slide rod 203 is slidably arranged in the circular through groove at the top of the first control rod 2, and a spring is sleeved on the outside of the second slide rod 203, and a through circular through groove structure is provided at the top of the second slide rod 203; a cylindrical liquid suction tube 4 is slidably arranged in the circular through groove of the second slide rod 203; a cylindrical pigment extrusion block 204 is fixedly arranged at the bottom end of the second slide rod 203, and the outer wall of the pigment extrusion block 204 is in contact with the inner wall of the first control rod 2, and a through circular through groove structure is provided in the middle of the bottom of the pigment extrusion block 204.

[0031] The bottom end of the first slide rod 101 is fixedly provided with a piston plate 102 of circular plate structure, and the outer wall of the piston plate 102 is in contact with the inner wall of the cylinder 1; a fixed ring 103 of circular ring structure is fixedly provided at the bottom inner side of the cylinder 1, two sets of rectangular sliding groove structures are provided on the outer side of the fixed ring 103, and a circular groove structure is provided on the top of the fixed ring 103. A limit control ring 201 is rotatably provided in the circular groove at the top of the fixed ring 103, and the bottom of the fixed ring 103 is in contact with the top of the marker pen 202; a sliding mounting block 3 is slidably provided in the rectangular sliding groove on the outer side of the fixed ring 103; and a cone-shaped cover 104 is fixedly provided at the bottom of the cylinder 1.

[0032] The specific usage and function of this embodiment are as follows: During use, the cover 104 and the cylinder 1 are placed on the outside of the breast, ensuring a tight fit between the cover 104 and the skin. Then, the first sliding rod 101 is pulled outwards along the cylinder 1, causing the piston plate 102 to slide outwards. This creates negative pressure on the inside of the cylinder 1 and the cover 104, adhering the cover 104 to the body. Under this negative pressure, the nipple is exposed from the indentation. After exposure, the first control rod 2 is rotated, causing the limiting control ring 201 and the marker pen 202 to rotate. Simultaneously, the marker pen 202 rotates, applying harmless pigment from the inside of the first control rod 2 to the fixed area. The bottom of the ring 103 is marked, and the pigment can be a harmless pigment that is easy to wash. By observing whether the mark is present on the bottom of the ring 103, it is possible to intuitively understand whether the device has been cleaned and disinfected before the next use, thus avoiding direct use if cleaning and disinfection are forgotten, reducing the risk of infection for women. Under the action of the spring on the outside of the second slide bar 203, the pigment squeezing block 204 applies pressure to the pigment inside the first control rod 2, so that the raw material can maintain the supply to the marker pen 202, thereby ensuring the effectiveness of the marking. The pigment can be a water-washable pigment that is non-toxic and harmless to the human body.

[0033] Example 2: Please refer to Figures 1 to 8 :

[0034] The second slide bar 203 has a cylindrical second control rod 205 rotatably mounted in the circular groove, and the top of the second control rod 205 has a through circular groove structure; a large gear 206 is fixedly mounted at the bottom of the second control rod 205.

[0035] The sliding mounting block 3 consists of two sets, both sets being rectangular blocks. The sliding mounting block 3 is connected to the limit control ring 201 via a threaded connection. A cylindrical drive shaft 301 is rotatably mounted on the inner side of the sliding mounting block 3. A worm gear 302 is fixedly mounted on the outer side of the drive shaft 301. A worm 303 is rotatably mounted on the inner side of the sliding mounting block 3, meshing with the worm gear 302. A small gear 304 is mounted on the top of the worm 303 via a key, meshing with a large gear 206. A cylindrical nipple stretching friction roller 305 is rotatably mounted on the bottom inner end of the sliding mounting block 3, and is connected to the drive shaft 301 via a conveyor belt. The outer side of the nipple stretching friction roller 305 can be wrapped with a foam-like layer to improve skin comfort and prevent discomfort caused by excessive friction during stretching.

[0036] The specific usage and function of this embodiment are as follows:

[0037] During rotation, the limit control ring 201 engages with the threaded joints of the two sets of sliding mounting blocks 3, allowing the two sets of sliding mounting blocks 3 to slide inward along the fixed ring 103. This synchronously drives the two sets of nipple stretching friction rollers 305 inward, causing the two sets of nipple stretching friction rollers 305 to make slight contact with both sides of the nipple, providing a certain clamping effect and preventing the nipple from resetting. Then, by rotating the second control rod 205 inside the second slide rod 203, the second control rod 205 drives the large gear 2. 06 rotates, and the large gear 206 synchronously drives the two sets of small gears 304 and worm 303 to rotate. The worm 303 drives the worm wheel 302 and the transmission shaft 301 to rotate synchronously. The transmission shaft 301 drives the nipple stretching friction roller 305 to rotate through the conveyor belt. Through the cooperation of the two sets of nipple stretching friction rollers 305, a certain friction force can be generated between them and the nipple. The two sets of nipple stretching friction rollers 305 lift the nipple outward. With the help of negative pressure, the correction effect on the nipple can be further improved.

[0038] Example 3: Please refer to Figures 1 to 8 :

[0039] The liquid suction tube 4 and the second control rod 205 are provided with a sealing structure; a negative pressure hollow ball 401 is fixedly installed on the top of the liquid suction tube 4. The negative pressure hollow ball 401 adopts an internally hollow spherical structure, and a one-way valve structure is provided at the connection between the negative pressure hollow ball 401 and the liquid suction tube 4; a liquid reservoir 402 is connected to the top of the negative pressure hollow ball 401 through a pipe. The liquid reservoir 402 adopts an internally hollow cylindrical structure, and a one-way valve structure is provided at the connection between the liquid reservoir 402 and the negative pressure hollow ball 401. An exhaust port structure is provided on the liquid reservoir 402.

[0040] The specific usage and function of this embodiment: In this invention, when milk is discharged from the nipple, causing liquid to appear inside the cylinder 1 and the cover 104, the liquid can be drawn up at any time through the liquid suction tube 4 according to the amount of milk discharged. The liquid suction tube 4 is slid up and down along the inner side of the second control rod 205, and the bottom end of the liquid suction tube 4 is aligned with the liquid area. Then, by squeezing the negative pressure hollow ball 401, the air inside the negative pressure hollow ball 401 is discharged into the liquid reservoir 402, and the air is discharged through the drain on the liquid reservoir 402. The air outlet discharges, creating negative pressure inside the negative pressure hollow ball 401. After releasing the negative pressure hollow ball 401, the liquid can pass through the liquid suction tube 4. Once the liquid reaches a certain amount, the liquid inside the negative pressure hollow ball 401 can be discharged into the liquid reservoir 402 by repeatedly squeezing the negative pressure hollow ball 401. At the same time, the liquid inside the cover 104 and the cylinder 1 can be completely absorbed, avoiding discomfort to the user and reducing the impact of the liquid on the adsorption effect of the cover 104.
