Description

Technical Field

[0001] The present invention relates to the technical field of breast pumps, and more specifically, to a multi-modal electric breast pump integrating low-frequency pulse and phototherapy. Background Art

[0002] Breast milk is the most ideal natural nutritional source for newborns, rich in almost all the nutrients required for infant growth. In particular, colostrum can significantly enhance the immunity and resistance of infants. However, affected by various factors, some parturients may experience problems such as delayed milk secretion, insufficient lactation, or breast distension and pain, which bring great distress to the body and mind. Physical exhaustion during childbirth, as well as the tension and anxiety during pregnancy and childbirth, may lead to imbalance of physiological functions, thus affecting milk secretion. In addition, congenital conditions or insufficient sucking ability of infants may also cause obstruction of milk flow, and even lead to problems such as mastitis and nipple cracks, affecting the smooth progress of breastfeeding. To alleviate these problems, breast pumps, as auxiliary tools, help to express milk by electric or manual means, and are applicable to situations where infants cannot directly suck breast milk, or mothers cannot breastfeed smoothly due to nipple discomfort, breast distension and pain, etc. In addition, for mothers who need to return to work but still hope to continue breastfeeding, breast pumps are also a practical and efficient support means.

[0003] Although traditional breast pumps have basic functions such as milk sucking, lactation promotion, and massage, they mainly rely on the breast shield to achieve different negative pressure suction or rhythm changes. Many novice mothers need to go to the hospital or postpartum care institutions for professional physiotherapy in addition to breastfeeding. Common physiotherapy methods usually involve artificial hot compress and massage first, then stimulation by manual extrusion or TENS electro-pulse equipment, and finally milk sucking with a breast pump. This method not only relies on manual operation and additional equipment, with a cumbersome process, but also increases the labor and material costs.

[0004] In the prior art, a Chinese utility model patent (application number: 202121921360.7) discloses an electric breast pump, including: at least one group of TENS electro-pulse generators, an air pipe, and electrode patches. The control PCB board is respectively connected to an electric air pump, an electromagnetic air valve, and a TENS electro-pulse generator. The electric air pump is connected to the electromagnetic air valve and then communicated with the air pipe. The TENS electro-pulse generator is connected to the electrode patches. This application can effectively reduce problems such as breast induration and pain of parturients and achieve the effect of smooth milk ducts by setting an additional group of electrode patches to provide low-frequency electrical stimulation pulse signals to the breasts of parturients. However, during the actual use of this device, it is necessary to additionally fix two electrode patches to provide low-frequency electrical stimulation signals to the breasts. On the one hand, the two electrode patches cannot cover the entire breast, and on the other hand, the fixation of the two electrode patches is likely to affect the normal use of the breast pump.

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only a part rather than all of the embodiments of the present invention.

[0051] Embodiment 1

[0052] To solve the above problems, the present invention provides a multi-modal electric breast pump integrating low-frequency pulse and light therapy, as Figures 1 - 10As shown, a milk container module 1 for containing milk; a negative pressure module 2 for generating negative pressure to suck milk from the breast and store it in the milk container module 1; a bra module 3 for at least sealing the nipple area so that the negative pressure module 2 sucks milk from the nipple; the bra module 3 includes at least two fitting parts 333 which extend radially from one end of the bra module 3 to the other end of the bra module 3; at least one electrode patch 5 is provided on each of the fitting parts 333, and the electrode patch 5 is used to apply an electrical pulse signal to the breast; at least one light therapy component 337 is provided on each of the fitting parts 333, and the light therapy component 337 is used to apply light to the breast; a main unit 6, with a pump module 4 and a control module arranged inside the main unit 6; the pump module 4 is used to suck the gas in the negative pressure module 2 to make the negative pressure module 2 generate negative pressure; the suction end of the pump module 4 is connected to the first end 311 of the negative pressure module 2, and the milk container module 1 is communicated with the bra module 3 through the second end 312 of the negative pressure module 2; the control module is configured to control the pump module 4 to provide negative pressure, and / or control the electrode patch 5 to apply an electrical pulse signal to the breast, and / or control the light therapy component 337 to apply light to the breast; the control module is electrically connected to the electrode patch 5, the pump module 4 and the light therapy component 337 respectively.

[0053] In this application, the milk container module 1 is used to hold the pumped-out milk for subsequent use. The negative pressure module 2 specifically includes an inner and an outer layer structure. Among them, the second opening 22 of the outer layer structure is connected to the milk container module 1, the third opening 23 of the outer layer structure is connected to the breast cup module 3, the inner layer structure is accommodated in the outer layer structure, and the first opening 21 of the inner layer structure is connected to the pump module 4. When the pump module 4 pumps air, the inner layer structure collapses inward, reducing the air pressure in the space between the outer layer structure and the inner layer structure. Then, milk is sucked out from the nipple and falls into the milk container module 1. To improve the adsorption effect of milk, this application further provides electrode pads 5 on the breast cup module 3. During the process of sucking milk, the breast cup module 3 can continuously fit with the breast area, and the electrode pads 5 located on the breast cup module 3 can also continuously fit with the breast, enabling lactating women to receive electro-pulse stimulation on the breast while sucking milk. Compared with the separately provided electrode pads 5 in the prior art, it can combine electro-stimulation physiotherapy with the milk-sucking process, reducing the user's complexity of use. It can also achieve electro-pulse stimulation throughout the milk-sucking process, assisting lactating women in stimulating mammary glands, promoting milk flow, and helping to dredge mammary ducts. The host 6 internally accommodates a pump module and a control module. The control module is provided in the form of a PCB circuit board. The pump module is electrically connected to the control module to extract air from the negative pressure module, causing the negative pressure module to compress inward and generate negative pressure in the milk container module 1 to extract milk. The control module can also be used to control the light therapy component 337 to emit different light radiations to the breast, and by controlling the wavelength of the light therapy, different light therapy effects can be achieved.

[0054] In one embodiment, as Figure 3 , Figure 4 , Figure 5 shown, the breast cup module 3 includes: a sealing flange 31, the sealing flange 31 has opposite first end 311 and second end 312 along the axial direction; the first end 311 is hermetically connected to the negative pressure module 2; the second end 312 is used to seal the nipple area; a first breast shield 32, the first breast shield 32 has opposite third end 321 and fourth end 322 along the axial direction; the third end 321 is detachably connected to the negative pressure module 2; the fourth end 322 is used to provide a supporting force to the breast. When the nipple area is hermetically connected to the sealing flange 31, the fourth end 322 abuts against the breast; a second breast shield 33, the second breast shield 33 has opposite fifth end 331 and sixth end 332 along the axial direction, the fifth end 331 is detachably connected to the negative pressure module 2, and the electrode pads 5 are embedded in the sixth end 332 to apply an electro-pulse signal to the breast; on the negative pressure module 2, the sealing flange 31, the first breast shield 32, and the second breast shield 33 are coaxially arranged in sequence from the inside to the outside.

[0055] In this application, the sealing flange 31 is used to contact the nipple part of a lactating woman and form a seal around and covering the nipple part. The sealing flange 31 can be replaced according to the size of the female nipple part. After the nipple part contacts the sealing flange 31, a sealed structure will be formed between the nipple part and the interior of the negative pressure module 2. When the negative pressure structure generates negative pressure, it will generate suction on the nipple part so that milk can flow out of the nipple under the attraction of the negative pressure. The first breast shield 32 is used to provide support for the breast. When the nipple part contacts the sealing flange 31, the first breast shield 32 can contact the skin near the areola to provide support for the breast, avoiding the pain caused by excessive pressure due to only the nipple part contacting the sealing flange 31 and affecting the milk sucking experience. The size of the second breast shield 33 is larger than that of the first breast shield 32. During actual use, the second breast shield 33 will contact the periphery of the breast to perform low-frequency electrical pulse stimulation on the part far from the areola and nipple, avoiding the problem that the low-frequency electrical pulse directly acts on the nipple and areola parts resulting in too strong a stimulation effect.

[0056] In one embodiment, as Figure 6 , Figure 8 shown, the second breast shield 33 includes at least two fitting parts 333, and the number of the fitting parts 333 is an even number; the fitting parts 333 extend radially from the fifth end 331 to the sixth end 332; at least one electrode sheet 5 is arranged on each fitting part 333.

[0057] Specifically, the fifth end 331 of the second breast shield 33 is circular, and the fitting parts 333 extend axially from the fifth end 331 to the sixth end 332, and the diameter of the circle formed by the fitting parts 333 at the sixth end 332 is larger than that of the fifth end 331, that is, the fitting parts 333 are arranged radially from the fifth end 331 to the sixth end 332. Such a setting can make the fitting parts 333 closer to the shape of the breast, and the fitting parts 333 can fit with the end of the breast to perform low-frequency electrical pulse stimulation on all areas of the breast as much as possible.

[0058] In one embodiment, the fitting parts 333 are dispersedly arranged around the axis of the second breast shield 33 in a centrally symmetric manner.

[0059] In one embodiment, the number of the fitting parts 333 is 6, and the distances between the respective fitting parts 333 are the same. The ends of the fitting parts 333 form a circle to perform all-round low-frequency electrical pulse stimulation on the breast.

[0060] In one embodiment, the electrode sheet 5 is arranged at the position of the sixth end 332 of the fitting part 333 to avoid applying an electrical pulse signal to the nipple or areola.

[0061] The electrode patch 5 is arranged at the sixth end 332, which can avoid the low-frequency electric pulses generated by the electrode patch 5 from causing too strong stimulation to the nipple and areola areas, affecting the use experience of lactating women, and enabling the low-frequency electric pulses to stimulate the milk glands inside the breast as much as possible, so that the milk in the glands can flow smoothly.

[0062] In one embodiment, the polarities of the electric pulse signals applied by any two electrode patches 5 in relative positions are opposite. Since the fitting parts 333 are arranged in pairs, the pulse signals applied by the electrode patches 5 in relative positions are opposite. If one electrode patch 5 is the positive electrode, then the polarity of the electrode patch 5 in the relative position is the negative electrode, so that the current can pass through the breast as much as possible to stimulate the internal glands.

[0063] In one embodiment, the second breast shield 33 further includes: a long fitting part 334; the length of the long fitting part 334 is greater than that of the other fitting parts 333; the long fitting part 334 is used to fit with the accessory mammary gland in the armpit area to apply an electric pulse signal.

[0064] The long fitting part 334 can apply an electric pulse stimulation to the accessory mammary gland area. For the left breast area, the long fitting part 334 is located at the 11 o'clock position, and for the right breast area, the long fitting part 334 is located at the 1 o'clock direction.

[0065] In one embodiment, as Figure 4 、 Figure 7 shown, the negative pressure module 2 includes a gooseneck three-way; the gooseneck three-way includes a first opening 21, a second opening 22 and a third opening 23; the first opening 21 is communicated with the pump module 4; the second opening 22 is communicated with the milk container module 1; the first end 311 is detachably connected to the inner side wall of the third opening 23; the third end 321 is detachably connected to the outer side wall of the third opening 23; the fifth end 331 surrounds the outer edge of the third opening 23, and the third end 321 is closer to the edge of the third opening 23 than the fifth end 331.

[0066] In the present application, a sealing airbag is arranged inside the gooseneck three-way. The top arc structure of the sealing airbag is made of soft silicone material, and the bottom of the sealing airbag is made of a hard material, such as plastic. The pump module 4 pumps air from the first opening 21, so that the top arc structure retracts inward, reducing the air pressure in the milk collection module, so that the milk is sucked out from the nipple.

[0067] As Figure 5 、 Figure 6As shown, in one embodiment, the inner diameter of the fifth end 331 is smaller than the outer diameter of the outer sidewall of the third opening 23; a break 335 is further provided at the fifth end 331, and the break 335 is provided in the gap between two adjacent fitting portions 333. The break 335 extends along the axial direction of the second breast shield 33, so that the fifth end 331 can expand to both sides from the break 335. In this embodiment, there is an interference fit between the ring of the fifth end 331 and the gooseneck tee. In order to facilitate the removal of the second breast shield 33 from the gooseneck tee for cleaning, a break 335 is also provided at the position of the fifth end 331. The break 335 can make the second breast shield 33 expand to both sides from the break 335 so that the second breast shield 33 can be removed from the gooseneck tee. Providing the break 335 at the fifth end 331 will not affect the FPC cable inside the fifth end 331. If the break 335 is not provided and the fifth end 331 is removed from the gooseneck tee by using the deformation ability of the silicone, the internal cable may be broken due to stretching. After providing the break 335, the internal cable can follow the bending of the fifth end 331, and the removal of the second breast shield 33 can be successfully achieved.

[0068] As Figure 9 , Figure 10 As shown, in one embodiment, the first end 311 of the sealing flange 31 is hermetically connected to the inner edge of the third opening 23 of the gooseneck tee to form a sealing structure capable of realizing negative pressure milk suction. Specifically, the outer diameter of the first end 311 of the sealing flange 31 is equal to or slightly larger than the inner diameter of the edge of the third opening 23 to form a sealing fit.

[0069] A support ring 313 for providing support strength is further provided at the outer edge of the sealing flange 31. The support ring 313 is made of a material different from that of the sealing flange 31. The sealing flange 31 is made of a skin-friendly and soft material, and the support ring 313 is made of a material with higher strength, so that the sealing flange 31 can maintain an annular shape and prevent the sealing flange 31 from deforming and affecting the sealing performance. The outer diameter of the support ring 313 is larger than the outer diameter of the sealing flange 31. The support ring 313 is close to the first end 311, but there is a certain distance from the edge of the first end 311 of the sealing flange 31. When the sealing flange 31 is installed on the third opening 23, the support ring 313 is located outside the third opening 23.

[0070] The third end 321 of the first breast shield 32 is provided with a barb portion 323. The barb portion 323 is annular. An annular groove is formed at the outer edge of the third opening 23, so that the barb portion 323 can be snapped into the annular groove for fixation. Specifically, the main body of the first breast shield 32 is made of a skin-friendly and soft material, and the barb portion 323 is made of a material with higher strength, so that the third end 321 of the first breast shield 32 can maintain a circular shape. The main body of the first breast shield 32 and the barb portion 323 are made by an integral molding process to achieve a firm connection. The first breast shield 32 is also provided with an annular pressing portion 324. The pressing portion 324 is arranged circumferentially. When the first breast shield 32 is installed on the gooseneck tee, the pressing portion 324 can tightly press the support ring 313 to prevent the sealing flange 31 from falling off. It can also utilize the tension of the first breast shield 32 to provide a pressing force on the support ring 313, so that the support ring 313 and the sealing flange 31 can be sealed and installed.

[0071] In one embodiment, an FPC flexible cable 336 is accommodated inside the second breast shield 33; a connection port 338 is provided at the fifth end 331; the connection port 338 is electrically connected to each electrode sheet 5 through the FPC flexible cable 336.

[0072] Embodiment 2

[0073] Unless otherwise specified, the structure in this embodiment is the same as that in Embodiment 1, and the difference lies in the FPC flexible cable 336 inside the fitting portion 333.

[0074] As Figure 3 、 Figure 5 、 Figure 8 、 Figure 9 As shown, in one embodiment, the sixth end 332 of the FPC flexible cable 336 is provided with a circular area. LEDs are arranged at the center of the circular area; a copper leakage area is arranged around the circular area. The copper leakage area is in direct contact with the skin, or is in contact with the skin through a conductor to apply an electrical pulse signal; the surface of the second breast shield 33 is coated with a liquid silicone layer; a conductive adhesive layer 340 is covered at the position of the electrode sheet 5, and a transparent silicone layer 339 is covered at the position of the phototherapy component 337; the transparent silicone layer 339 and the conductive adhesive layer 340 are integrally formed with the liquid silicone layer by an insert molding process; at the sixth end 332 position, the electrode sheet 5 is arranged around the phototherapy component 337, and the conductive adhesive layer 340 is arranged around the transparent silicone layer 339. The conductive adhesive layer 340 and the liquid silicone layer are both made of non-transparent silicone materials.

[0075] The red and blue light generated by the phototherapy component 337 are low-energy visible lights with limited penetration depth, which can only penetrate the epidermis to the superficial layer of the dermis and will not affect the milk composition or the health of the baby. Installing the phototherapy component 337 on the FPC cable and wrapping the FPC flexible cable 336 in liquid silicone can make the phototherapy component 337 fit the shape of the female breast more closely, avoid light pollution generated during the use of the phototherapy component 337, direct the light to the target area, avoid light scattering to the areola or nipple, and ensure breastfeeding safety.

[0076] In one embodiment, due to the pigment deposition in the areola area and the darker color, if the light signal generated by the phototherapy component 337 directly irradiates the areola area, it may stimulate the sensitive nerve endings around the areola, causing pain or a burning sensation and interfering with the breastfeeding experience. Therefore, compared with the fifth end 331, the phototherapy component 337 is closer to the sixth end 332 to avoid irradiating the areola area. To avoid light pollution caused by light leakage during phototherapy, in this embodiment, only the transparent silicone layer 339 is made of a transparent material to facilitate the passage of light, and the liquid silicone layer and the conductive adhesive layer 340 are both non-transparent materials to block the light emitted by the LED, so that the light can only be irradiated to a specific area and reduce light pollution.

[0077] As Figure 8 shown, in one embodiment, the phototherapy component 337 is specifically an LED array. The phototherapy component 337 and the electrode patch 5 are coaxially arranged, and the electrode patch 5 surrounds the phototherapy component 337. While applying an electrical pulse stimulation to the mammary gland, light therapy is applied to the mammary gland; the area of the phototherapy component 337 is covered with a transparent silicone layer 339; the transparent silicone layer 339, the conductive adhesive layer 340 and the liquid silicone layer are all integrally formed by the overmolding process. Among them, the conductive adhesive layer 340 and the liquid silicone layer are both made of non-transparent silicone materials. Wrapping the transparent silicone layer 339 with non-transparent materials can avoid light pollution caused by light leakage from the phototherapy component and affect the use experience. In this application, the FPC flexible cable realizes the transmission of the electrical pulse signal by setting a copper leakage area. To avoid corrosion of the copper leakage area and reduce the resistance of the electrode patch, it is also necessary to cover the copper leakage area with a conductive adhesive. Further, a soft steel sheet can also be covered on the copper leakage area to improve the conductivity of the electrode patch. The LED array of the phototherapy component 337 is arranged at the center of the copper leakage area, and different light signals can be controlled by setting multiple LEDs to achieve different phototherapy purposes.

[0078] The FPC flexible flat cable 336 uses a polyimide or PET substrate, which has high flexibility and stretchability, and can adaptively adjust according to the dynamic changes in breast volume. The LED array is fixed on the FPC through micro-bump welding technology to further disperse stress and extend the service life. The liquid silicone layer is integrally formed through the overmolding process, forming a seamless connection with the FPC and the transparent silicone layer 339 to avoid friction or curling at the joints. The integrated fitting part 333 is made through the overmolding process, enabling a waterproof process for the entire structure, facilitating the removal of the fitting part 333 from the gooseneck tee for cleaning. The colorless transparent silicone allows efficient penetration of red / blue light to the subcutaneous tissue, and at the same time evenly scatters the light through scattering particles, making the light generated by the light therapy component 337 softer and avoiding local overheating or burns caused by concentrated light spots. The LED can efficiently convert electrical energy into light energy, reducing the generated heat and avoiding skin burns. The full silicone coverage achieved through the overmolding process can also isolate the LED electrodes with the silicone layer to prevent short circuits caused by milk or sweat, improving safety.

[0079] In one embodiment, the wavelength range of the optical signal emitted by the light therapy component 337 is 630 nm - 700 nm and / or 400 nm - 470 nm and / or 800 nm - 900 nm, the light intensity is 50 - 150 mW / cm 2 , and the pulse duty cycle is 30% - 70%. Among them, 630 - 700 nm is the red light band. Red light can promote local blood vessel dilation, relieve the swelling pain caused by stasis mastitis, and accelerate the repair of micro-injuries in breast tissue. 400 nm - 470 nm is the blue light band. Blue light can selectively inactivate Staphylococcus aureus, reduce the risk of abscess formation, and reduce the dependence on antibiotics. 800 nm - 900 nm is near-infrared light, and the penetration depth exceeds 5 mm, effectively preventing the dilation of lactating mammary ducts.

[0080] In one embodiment, the frequency of the electrical pulse signal is specifically: 1 - 200 Hz; the width of the electrical pulse signal is 50 μs - 500 μs, and the current intensity of the electrical pulse signal is 0 - 10 mA. In one embodiment, the electrical pulse signal can also identify the impedance of the skin according to the impedance matching technology, so that the output current can match the data of the human skin, making the current parameters appropriate, avoiding pain caused by excessive current or affecting the electrostimulation effect due to too small current.

[0081] Embodiment Three

[0082] Unless otherwise specified, the structure in this embodiment is the same as that in Embodiment One. The difference is that a first connection port 338 is provided on the second breast shield 33, and a second connection port is provided on the host.

[0083] The interior of the second breast shield is provided with an FPC flexible cable; the fifth end is provided with a first connection port 338; the first connection port 338 is electrically connected to each electrode sheet through the FPC flexible cable; the first connection port 338 is also electrically connected to each phototherapy component through the FPC flexible cable; the first connection port 338 is specifically a magnetic contact connection port, or the first connection port 338 is specifically a TYPE-C connection port;

[0084] The main body is also provided with a second connection port, and the second connection port is electrically connected to the control module inside the main body; the second connection port is specifically a TYPE-C connection port, and the first connection port 338 is detachably electrically connected to the second connection port through a wire

[0085] The second connection port on the main body is a TYPE-C connection port. Through the second connection port, the FPC flexible cable can be electrically connected to the module inside the main body through a wire to receive the control signal output by the control module to apply an electrical pulse stimulation or light therapy to the breast. As Figure 15 shown, it is the pin definition diagram of the second connection port, that is, the TYPE-C connection port. Among them, LED+ is used to control whether the phototherapy component lights up or goes out; ID0 and ID1 are used to identify the type of external device. When the external device is a breast pump, the control component will control the output of a stronger electrical pulse signal. When the external device is a pelvic floor muscle repair component, the control component will control the output of a relatively weaker electrical pulse signal. PS1+, PS1-, PS2+, and PS2- are respectively used to deliver electrical pulse signals to two groups of electrode sheets to realize electrical stimulation pulses for the mammary gland or pelvic floor muscle.

[0086] In one embodiment, it further includes a pelvic floor muscle repair component 7. The pelvic floor muscle repair component 7 is communicatively connected to the control module. The pelvic floor muscle repair component 7 is used to apply an electrical pulse signal to the pelvic floor muscle; the pelvic floor muscle repair component 7 is provided with a third connection port 338. The third connection port 338 is connected to the second connection port 338 through a wire, and the third connection port 338 is the same as the first connection port 338.

[0087] The pelvic floor muscle repair component 7 is also electrically connected to the control module in the main body 6 through the second connection port 338 to apply an electrical pulse stimulation to the pelvic floor muscle. Since the pelvic floor muscle repair component 7 applies an electrical pulse stimulation to the mucous membrane, and the resistance of the mucous membrane part is less than that of the skin, in order to avoid damage to the mucous membrane part, it is necessary to reduce the intensity of the electrical pulse signal applied by the pelvic floor muscle repair component 7. Specifically, by adding identification resistors in the pelvic floor muscle repair component 7 and the second breast shield 33 respectively, when different connectors are connected to the second connection port 338, it is possible to judge whether the component is the pelvic floor muscle repair component 7 or the second breast shield 33 according to the size of the identification resistor, and then automatically control parameters such as the intensity and frequency of the output electrical stimulation pulse.

[0088] In one embodiment, the first connection port 338 is specifically a magnetic contact connection port. The first connection port 338 and the FPC flexible cable 336 are externally coated with a liquid silicone layer; a conductive adhesive layer is covered at the position of the electrode sheet 5, and the conductive adhesive layer and the liquid silicone layer are integrally formed by the overmolding process. Setting the first connection port 338 as a magnetic contact connection port and wrapping the magnetic contact connection port in the liquid silicone layer through the overmolding process can achieve all-round waterproofing of the second breast shield 33, facilitating the disassembly and cleaning of the second breast shield 33. The magnetic contact first connection port 338 can also facilitate the user to connect the connector. Using magnetic connection, it can automatically identify the positive and negative poles of the contacts, avoiding reverse connection of the connecting wires and affecting the operation of the device.

[0089] In one embodiment, the third connection port on the pelvic floor muscle repair component 7 and the first connection port are of the same type of connection port. By setting the same type of connection port, the universality of the wires can be achieved, facilitating the installation and disassembly operations for the user.

[0090] In one embodiment, the FPC flexible cable is communicatively connected to the control module through the magnetic contact connection port. The control module can be implemented by an integrated circuit such as a single-chip microcomputer or an MCU that can execute a predetermined program. By executing the predetermined program, before milk extraction, during milk extraction, and after milk extraction, light therapy and / or electrical pulse stimulation can be performed on the breast. The specific functions can be selected and controlled according to the actual needs of the user. In this embodiment, through the precise matching of the low-frequency micro-current characteristics and the physiological needs of the breast, multiple functions such as pain relief, circulation improvement, inflammation regulation, and support for milk discharge in lactation breast care are achieved.

[0091] In this embodiment, the pelvic floor muscle repair component 7 and the second breast shield 33 adopt the same type of magnetic contact connection port 338. The pelvic floor muscle repair component 7 can achieve interface reuse with the second breast shield 33, reducing the complexity of the device. In addition, the control component can also control various functions through the internal control circuit.

The running light component can emit light or go out according to a predetermined program, and can provide a breathing guidance function for the user during the process of milk suction and low-frequency electrical pulse stimulation, providing a peaceful and relaxed state of mind and body. Let the user mother complete milk suction and physiotherapy with a happy body and mind in a healthy atmosphere.
