[0024] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0025] Embodiment 1, in combination with the attached Figures 1-3 , a milk addition beside the breast and nipple protection integrated device, including a breast shield 1 and a tube 2. The breast shield 1 is made of medical-grade silicone material, and the tube 2 is made of medical-grade hose;

[0026] The nipple of the breast shield 1 and the part near the nipple adopt a double-layer structure design, including an outer layer 101 and an inner layer 102, so that a cavity 103 is formed in the breast shield 1 at the nipple and the part near the nipple. A micro flow sensor 3 is provided on the inner side of the inner layer 102 near the nipple outlet. A connecting hose 4 is provided between the outer layer 101 and the inner layer 102. One end of the connecting hose 4 is communicated with the inner side of the nipple part of the inner layer 102, and the connecting hose 4 is hermetically connected to the inner layer 102. The other end of the connecting hose 4 extends to the outside of the outer layer 101 and is hermetically connected to the outer layer. An external thread is provided on the outer side of the extending end of the connecting hose 4. The micro flow sensor 3 is electrically connected to a wireless transmission module. The micro flow sensor 3 is located between the nipple outlet of the breast shield 1 and the port of the connecting hose 4;

[0027] One end of the tube 2 is connected with a connector 201. An internal thread matching the connecting hose 4 is provided inside the connector 201. A check valve 5 and a flow regulator 6 are provided on the tube 2.

[0028] In the specific implementation of the present invention, the catheter 2 is inserted into the feeding bottle, the nipple and areola are cleaned with a sanitary napkin, the breast shield 1 is turned outwards, the breast shield 1 is brought close to the breast, the nipple is placed in the nipple part of the inner layer 102, gently pressed, and the breast shield 1 is turned back to be closely attached to the breast. The baby can suck the milk from the nipple on the breast shield 1 or the milk in the feeding bottle. Among them, the flow rate of the catheter 2 can be adjusted by the flow regulator 6. Through this operation, two situations can be achieved: 1. When the flow regulator 6 makes the milk in the catheter 2 unable to flow, at this time, when the baby sucks the nipple on the breast shield 1, the milk in the mother's body enters the nipple part of the inner layer 102 through the nipple, passes through the micro flow sensor 3, and then enters the baby's mouth through the nipple outlet of the breast shield 1, realizing pure breast milk sucking; 2. When the flow regulator 6 only changes the flow rate of the liquid in the catheter 2, at this time, when the baby sucks the nipple on the breast shield 1, not only the milk in the mother's body enters the nipple part of the inner layer 102 through the nipple, passes through the micro flow sensor 3, and then enters the baby's mouth through the nipple outlet of the breast shield 1, but also the milk in the feeding bottle enters the nipple part of the inner layer 102 through the catheter 2 and the connecting hose 4, passes through the micro flow sensor 3, and then enters the baby's mouth through the nipple outlet of the breast shield 1, realizing simultaneous sucking of breast milk and milk. Among them, the one-way valve 5 ensures the one-way flow of the milk in the catheter 2.

[0029] In this specific embodiment, the micro flow sensor 3 adopts the Flusso FLS110 MEMS flow sensor. Its size: 3.5×3.5 mm (package size), flow range: 0.001 - 500 standard liters per minute (can be adjusted according to specific configurations), based on CMOS MEMS technology, without moving parts, high reliability, suitable for low-pressure liquid (such as water, chemical solution) flow measurement, with a compact package (6-pin DFN package), suitable for scenarios such as consumer electronics and medical devices. By setting a wireless transmission module and installing a supporting APP on the user's mobile phone, the breastfeeding flow can be monitored, which is convenient for the mother to understand the breastfeeding situation. Specifically, the wireless transmission module adopts a Bluetooth transmission module.

[0030] In this specific embodiment, the inner layer 102 is provided with a connecting part adapted to the micro flow sensor 3. The connecting part includes an upper limit ring 104 and a lower limit ring 105. The connecting part is made of the same material as the breast shield 1 and is integrally formed with the breast shield 1. The micro flow sensor 3 is placed in front of the upper limit ring 104 and the lower limit ring 105, making the disassembly and assembly of the micro flow sensor 3 convenient and facilitating the regular cleaning of the surfaces of the breast shield 1 and the micro flow sensor 3.

[0031] In this specific embodiment, a plurality of negative pressure generating rings 106 are provided at the inner lower edge of the breast shield 1. The plurality of negative pressure generating rings 106 are concentric. The negative pressure generating rings 106 are made of the same material as the breast shield 1 and are integrally formed with the breast shield 1. Through the negative pressure effect, the breast shield is stably adsorbed on the breast to prevent displacement. Specifically, insert the conduit 2 into the milk bottle, clean the nipple and areola with a sanitary cotton, turn the breast shield 1 outward, bring the breast shield 1 close to the breast, place the nipple into the nipple part of the inner layer 102, gently press, turn the breast shield 1 back, after it is close to the breast, press the edge of the breast shield 1 by hand, and part of the air between adjacent negative pressure generating rings 106 will be discharged to form a negative pressure. After releasing the hand, the breast shield 1 can be tightly adsorbed on the breast under the negative pressure of its edge, ensuring the sealing between the breast shield 1 and the breast, so that the milk or breast milk can flow smoothly.

[0032] In this specific embodiment, the number of the negative pressure generating rings 106 is not less than 3, so as to form at least two negative pressure chambers to ensure the reliability of negative pressure generation.

[0033] In this specific embodiment, a spiral steel wire is provided inside the tube wall of the conduit 2, and a spiral anti-kinking design is adopted to ensure the smooth flow of milk in the conduit 2 and avoid milk blockage caused by kinking.

[0034] In this specific embodiment, the conduit 2 is made of a platinum-cured silicone hose. The platinum-cured silicone hose can usually be used for a long time in the temperature range of -60°C to +200°C, and has poor thermal conductivity. The temperature of the breast milk drops slowly when it is transported through the conduit 2, so that the breast milk can be maintained at a suitable temperature of 37±1°C, ensuring that the baby can ingest breast milk at a suitable temperature. In addition, the platinum-cured silicone hose has strong chemical corrosion resistance, has excellent tolerance to most chemical substances (such as acids, alkalis, salts, etc.), is suitable for transporting various corrosive media, is suitable for transporting dairy products and beverages, is resistant to grease, and is easy to clean, meeting the FDA food contact material standard; has good biocompatibility, is non-toxic and odorless, meets medical-grade standards such as FDA and USP Class VI, and can be directly in contact with food and drugs; has excellent elasticity and flexibility. The platinum curing process improves the cross-linking density of the silicone, making the hose have better elasticity and flexibility, and is easy to bend and install; has high transparency, and the hose is usually transparent or semi-transparent, facilitating the observation of the internal fluid state.
