Description

Technical Field

[0001] The utility model relates to the technical field of correction instruments, in particular to a nipple depression correction device based on negative pressure suction. Background Technique

[0002] Due to the influence of congenital and acquired factors, some women have the problem of nipple depression. Specifically, different individuals of women usually have different nipple shapes. One abnormal nipple shape is nipple depression, which is mostly a physiological defect caused by congenital development. After childbirth, the sunken nipples of these women bring certain difficulties to breastfeeding. The problem is that the baby cannot suck the nipples, resulting in a lack of breast milk, greatly increasing the difficulty of breastfeeding. Among the existing solutions, the negative pressure suction method is used to pull out and correct the nipples.

[0003] Currently, the commonly used correction methods mainly include surgical treatment and treatment with a corrector (orthosis). The corrector based on the negative pressure suction method is suitable for patients with mild and moderate depression, and there are a large number of patients with nipple depression who can be corrected in this way. In practice, the common corrector is modified by removing the needle part of an empty syringe. After retrieval and comparison, its basic configuration is disclosed in the technical solution provided in the patent application number: CN202322457971.6. Such a corrector has a simple structure, but there is also a problem that the operation process cannot be completed independently by the patient. Therefore, some patients think that its privacy is not strong, and it is difficult for the patient to control the negative pressure, which is likely to cause strong discomfort to the patient during the suction process.

[0004] It is necessary to provide a correction device that can be operated by the patient himself and is easy to adjust the negative pressure suction force. Content of the Utility Model

[0005] In view of the correction needs of patients with nipple depression, the utility model provides a nipple depression correction device based on negative pressure suction. The correction device obtains the negative pressure condition required for suction through a negative pressure pump, avoiding the use of a pull rod to obtain this condition, so that the patient himself can complete the entire operation process; when the negative pressure suction causes discomfort to the patient, the suction force can be conveniently adjusted through the air intake device.

[0006] The specific technical solution is as follows: A nipple depression correction device based on negative pressure suction includes a negative pressure cover in the shape of a bell mouth and a negative pressure generating device. It also includes an installation cylinder connected to the rear end of the negative pressure cover. A flexible isolation cover is arranged inside the installation cylinder. The isolation cover divides the space inside the installation cylinder into a front space and a rear space. The cavity on the negative pressure cover communicates with the front space. The negative pressure generating device includes a negative pressure pump. The suction port of the negative pressure pump communicates with the rear space through a negative pressure pipe. It also includes an air intake device. The air intake device includes an air intake pipeline and a cut-off valve. The air intake pipeline is connected to the rear space. The cut-off valve is used to control the on / off state of the air intake pipeline.

[0007] In the prior art, the usage method of a commonly used nipple depression correction device based on negative pressure suction is as follows: The negative pressure cover is attached to the breast so that the front end of the negative pressure cover is closed by the breast. Then, the piston in the piston cylinder is pulled by a pull rod. The piston moves backward to form a negative pressure in the negative pressure cover, and the depressed nipple is corrected by negative pressure traction. In such a structure, during use, usually one hand is needed to hold the negative pressure cover to maintain its position, and two hands are needed to operate the piston cylinder and the pull rod. Patients with nipple depression cannot complete all operations alone.

[0008] To enable patients to independently complete the entire correction process, this solution provides an electric solution. During use, the patient holds the negative pressure cover with one hand to maintain its position on the breast, and then operates the control element of the negative pressure pump with the other hand to pneumatically drive the negative pressure pump. The negative pressure pump evacuates the rear space. After reaching a certain vacuum degree, the isolation cover deforms, so that the air pressure in the front space decreases. At this time, the negative pressure cover exerts an attracting effect on the depressed nipple and sucks out the nipple, achieving the purpose of nipple depression correction.

[0009] In this solution, an environment for nipple attraction is obtained by electric energy. The user only needs to operate the negative pressure pump. Not only can patients complete the operation by themselves, but also the operation is simple and convenient to use. In this solution, an isolation cover is provided. The isolation cover divides the inner area of this device, so that the aspirated substances that may appear during the correction process are retained in the front space, making this solution have the characteristic of being convenient to clean. In this solution, the negative pressure environment inside the negative pressure cover is realized through the isolation cover, which can make the change of the vacuum degree inside the negative pressure cover slower. At the same time, by restricting the deformation amount of the negative pressure cover, the maximum vacuum degree inside the negative pressure cover can be controlled, avoiding excessive negative pressure suddenly reached and causing pain to patients, and also ensuring the safety of use to a certain extent. This solution also includes an air intake device. The specific application is as follows: When the patient feels that the attraction is too strong and there is discomfort or pain, the cut-off valve can be opened to use the air intake pipeline to reduce the pressure difference between the rear space and the external atmosphere, so as to increase the pressure in the front space and reduce the attracting force of the negative pressure cover on the breast.

[0010] In a specific embodiment, both the isolation cover and the negative pressure cover are made of silica gel. The isolation cover can be fixed in the mounting cylinder or the isolation layer can be set to be detachable, so that it is convenient to clean the relevant front-end components after the device is used.

[0011] In a specific embodiment, the mounting cylinder is a cylindrical structure with a fixed connection at the front end to the negative pressure cover and an open rear end, and further includes a connection plate. The rear end of the mounting cylinder and the connection plate form a detachable connection relationship through connection threads; the isolation cover is a bowl-shaped structure made of silica gel. The open end of the isolation cover has an outwardly protruding bowl rim. The isolation cover is embedded in the mounting cylinder, and the open end of the isolation cover faces the connection plate. The bowl rim is clamped between the bottom plate of the connection plate and the rear end of the mounting cylinder.

[0012] This implementation provides a specific structure form and installation method of the isolation cover. The shape of the isolation cover is the same as that of the isolation cover on traditional breast pumps. When in use, first separate the mounting cylinder and the connection plate, and then place the isolation cover into the mounting cylinder from the rear end of the mounting cylinder. At this time, the front side of the bowl rim is in contact with the rear end of the mounting cylinder, and then dock the rear end of the mounting cylinder with the connection plate. During the process of rotating the mounting cylinder or the connection plate to achieve connection through the connection threads, the front side of the bottom plate of the connection plate is in contact with the rear side of the bowl rim, and the isolated front side space and rear side space are obtained by using the isolation cover. When the negative pressure pump works, the main body on the isolation cover continuously collapses. During this process, the air pressure in the front side space continuously decreases until a vacuum degree capable of attracting the nipple is generated in the negative pressure cover. This solution provides an implementation method that is convenient for disassembling and installing the isolation cover. The front side space and the rear side space are reliably sealed. After disassembly, the structure formed by the negative pressure cover and the mounting cylinder has openings at both the front and the rear. This structure and the separated isolation cover are both characterized by convenient cleaning.

[0013] In a specific embodiment, it further includes a cylindrical outer shell. The rear end of the mounting cylinder is fixedly connected to the front end of the outer shell. The cut-off valve is an electromagnetic valve. Both the negative pressure pump and the air intake device are fixed inside the outer shell. It further includes a storage battery arranged inside the outer shell, and the storage battery is used to supply power to the negative pressure pump and the electromagnetic valve.

[0014] This implementation provides a compact structural form. Specifically, the housing provides an installation space for the negative pressure pump and the air intake device. The negative pressure cover and the installation cylinder are installed at the front end of the housing. After the battery has sufficient power, there is no need to connect an external power supply to this device. Operating the solenoid valve and the negative pressure pump can be achieved by operating the relevant buttons. It can also be set that this device includes a Bluetooth module and a processor. The Bluetooth module establishes two-way communication with the mobile phone, and displays working data and provides an operation interface through the mobile phone APP. The patient holds the housing with one hand, making the negative pressure cover close to the breast, and operates the mobile phone with the other hand. Through the mobile phone display interface, this correction device can be operated and information such as the negative pressure in the corresponding negative pressure tube or negative pressure cover and the negative pressure duration can be obtained. Specifically, for example: through the operation buttons on this device or the operation interface of the mobile phone APP, the negative pressure formed in the negative pressure cover can be operated to have multiple gears; through the operation buttons on this device or the operation interface of the mobile phone APP, the negative pressure frequency in the negative pressure cover can be set. For example, after the negative pressure works for N seconds, it switches to normal pressure for M seconds, and such negative pressure - normal pressure correction actions are repeated within the set time; for continuous negative pressure work, when the single negative pressure duration reaches the set time, a warning reminder is provided through the warning component existing on this correction device itself, through the mobile phone, etc. The warning reminder includes but is not limited to beeping, light prompts, etc.; the maximum negative pressure duration is built-in to avoid damage to the breast caused by misoperation; a rechargeable lithium battery is used as the battery to ensure the single support duration of the battery while controlling the weight; a type-c interface is set for charging and internal parameter adjustment; the battery capacity is greater than or equal to 1100 mA to meet the power consumption needs of a general single treatment course; the housing material is made of polypropylene with good mechanical properties and resistance to liquid corrosion to be suitable for the hospital environment.

It also includes a PCB board arranged inside the housing and behind the mounting plate. The control elements of the negative pressure pump and the solenoid valve are arranged on the PCB board. It further includes a base installed at the rear end of the housing. The base closes the rear end of the housing.

[0018] In this implementation method, during use, the soft pad is inserted into the negative pressure cover from the front end of the negative pressure cover. For example, in the supporting products, it is set that this device is equipped with multiple soft pads with different inner shapes, and the patient can choose a soft pad that better suits the shape of their own breasts during use, so as to provide more comfortable support for the breasts during the negative pressure suction process.

[0019] In a specific embodiment, a protruding structure is provided on the inner side of the soft pad.

[0020] In this implementation method, for the negative pressure - normal pressure switching action existing in the operation process, the protruding structure is used to provide local extrusion for the area around the nipple, achieving the purpose of massage and nipple extrusion.

Specific embodiments

[0039] The following further elaborates on the present utility model in conjunction with embodiments, but the present utility model is not limited to the following embodiments:

[0040] Embodiment 1:

[0041] As Figures 1 to 3 , a nipple depression correction device based on negative pressure suction includes a negative pressure cover 3 in the shape of a flared mouth and a negative pressure generating device, and further includes a mounting cylinder 4 connected to the rear end of the negative pressure cover 3. A flexible isolation cover 5 is arranged in the mounting cylinder 4. The isolation cover 5 divides the space in the mounting cylinder 4 into a front space and a rear space. The cavity on the negative pressure cover 3 communicates with the front space; the negative pressure generating device includes a negative pressure pump 10. The suction port of the negative pressure pump 10 communicates with the rear space through a negative pressure tube 7; it further includes an air intake device 9. The air intake device 9 includes an air intake pipeline and a cut-off valve. The air intake pipeline is connected to the rear space, and the cut-off valve is used to control the on / off state of the air intake pipeline.

[0042] In the prior art, the common usage method of a nipple depression correction device based on negative pressure suction is as follows: The negative pressure cover 3 is attached to the breast, so that the front end of the negative pressure cover 3 is closed by the breast. Then, the piston in the piston cylinder is pulled by a pull rod. The piston moves backward to form a negative pressure in the negative pressure cover 3, and the nipple is corrected by negative pressure traction. In the process of using such a structure, usually one hand needs to support the negative pressure cover 3 to maintain its position, and two hands are required to operate the piston cylinder and the pull rod. A patient with nipple depression cannot complete all the operations alone.

[0043] To enable the patient to complete the entire correction process independently, this solution provides an electric solution. During use, the patient holds the negative pressure cover 3 with one hand to maintain its position on the breast, and then operates the control element of the negative pressure pump 10 with the other hand to actuate the negative pressure pump 10. The negative pressure pump 10 evacuates the rear space. After reaching a certain vacuum degree, the isolation cover 5 deforms, causing the air pressure in the front space to decrease. At this time, the negative pressure cover 3 attracts the sunken nipple and sucks out the nipple, achieving the purpose of nipple inversion correction.

[0044] In this solution, an environment for nipple attraction is obtained by electric energy. The user only needs to operate the negative pressure pump 10. Not only can the patient complete the operation by himself, but also the operation is simple and convenient to use. In this solution, it is set to include an isolation cover 5. The isolation cover 5 divides the inner area of the device, so that the aspirated substances that may appear during the correction process are retained in the front space, making this solution have the characteristic of being convenient to clean. In this solution, the negative pressure environment inside the negative pressure cover 3 is realized through the isolation cover 5, which can make the change of the vacuum degree inside the negative pressure cover 3 slower. At the same time, by restricting the deformation amount of the negative pressure cover 3, the maximum vacuum degree inside the negative pressure cover 3 can be controlled, avoiding excessive negative pressure suddenly reached and causing pain to the patient, and also ensuring the safety of use to a certain extent. In this solution, an air intake device 9 is also included. The specific application is as follows: when the patient feels that the attraction force is too large and there is uncomfortable pain, the cut-off valve can be opened, and the pressure difference between the rear space and the external atmosphere can be reduced by using the air intake pipeline, so as to increase the pressure in the front space and reduce the attraction force of the negative pressure cover 3 on the breast.

[0045] More specifically, both the isolation cover 5 and the negative pressure cover 3 are made of silicone material. The isolation cover 5 can be fixed in the installation cylinder 4, or it can be set that the isolation layer is detachable. In this way, it is convenient to clean the relevant front-end components after the device is used.

[0046] More specifically, the installation cylinder 4 is a cylindrical structure with a fixed connection at the front end to the negative pressure cover 3 and an open end at the rear end. It also includes a connection disk 6. The rear end of the installation cylinder 4 and the connection disk 6 form a detachable connection relationship through connection threads; the isolation cover 5 is a bowl-shaped structure made of silicone material. The open end of the isolation cover 5 has an outwardly convex bowl edge 51. The isolation cover 5 is embedded in the installation cylinder 4, and the open end of the isolation cover 5 faces the connection disk 6. The bowl edge 51 is clamped between the bottom plate of the connection disk 6 and the rear end of the installation cylinder 4.

[0047] This implementation provides a specific structure and installation method for the isolation cover 5. The shape of the isolation cover 5 is the same as that of the isolation cover 5 on traditional breast pumps. When in use, first separate the installation cylinder 4 from the connection plate 6, and then insert the isolation cover 5 into the installation cylinder 4 from the rear end of the installation cylinder 4. At this time, the front side of the bowl edge 51 is in contact with the rear end of the installation cylinder 4, and then dock the rear end of the installation cylinder 4 with the connection plate 6. During the process of rotating the installation cylinder 4 or the connection plate 6 to achieve connection through the connection thread, the front side of the bottom plate of the connection plate 6 is in contact with the rear side of the bowl edge 51, and the separated front space and rear space are obtained by using the isolation cover 5. When the negative pressure pump 10 works, the main body on the isolation cover 5 continuously deflates. During this process, the air pressure in the front space continuously decreases until a vacuum degree capable of attracting the nipple is generated in the negative pressure cover 3. This solution provides an implementation method for conveniently disassembling and assembling the isolation cover 5. The front space and the rear space are reliably sealed. After disassembly, the structure formed by the negative pressure cover 3 and the installation cylinder 4 has openings at both the front and the rear. Both this structure and the separated isolation cover 5 are characterized by convenient cleaning.

After the battery 11 has sufficient power, there is no need to externally connect a power supply to this device. Operating the solenoid valve and the negative pressure pump 10 can be achieved by operating the relevant buttons. It can also be set that this device includes a Bluetooth module and a processor. The Bluetooth module establishes two-way communication with the mobile phone, and displays working data and provides an operation interface through the mobile phone APP. The patient holds the housing 12 with one hand, presses the negative pressure hood 3 against the breast, and operates the mobile phone with the other hand. Through the mobile phone display interface, this correction device can be operated and information such as the negative pressure in the corresponding negative pressure tube 7 or the negative pressure hood 3 and the negative pressure duration can be obtained. Specifically, for example: through the operation buttons existing on this device or the operation interface of the mobile phone APP, the negative pressure formed in the negative pressure hood 3 can be operated to have multiple gears; through the operation buttons existing on this device or the operation interface of the mobile phone APP, the negative pressure frequency in the negative pressure hood 3 is set. For example, after the negative pressure works for N seconds, it switches to normal pressure for M seconds, and such negative pressure - normal pressure correction actions are repeated within the set time; for continuous negative pressure work, when the single negative pressure duration reaches the set time, a warning reminder is provided through the warning component existing on this correction device itself, through the mobile phone, etc. This warning reminder includes but is not limited to beeping, light indication, etc.; the maximum negative pressure duration is built-in to avoid damage to the breast caused by misoperation; a rechargeable lithium battery is used as the battery 11 to ensure the single support duration of the battery 11 while controlling the weight; a type-c interface is set for charging and internal parameter adjustment; the capacity of the battery 11 is greater than or equal to 1100 mA to meet the power consumption needs of a general single treatment course; the material of the housing 12 is polypropylene with good mechanical properties and resistance to liquid corrosion to be suitable for the hospital environment.

The base 15 closes the rear end of the housing 12. The control knob of the control element passes through the base 15 and is exposed outside the base 15.

[0051] This implementation provides a layout of specific functional components inside the housing 12. The mounting plate 13 serves as a carrier plate for the negative pressure pump 10 and the air intake device 9. The PCB board 14 serves as a carrier plate for the corresponding control elements and circuits.

[0054] More specifically, a protruding structure 2 is provided on the inner side of the soft pad 1.

[0055] In this implementation, for the negative pressure - normal pressure switching action during the operation process, the protruding structure 2 is used to provide local extrusion to the area around the nipple, achieving the purpose of massage and nipple extrusion.
