Description

Technical Field

[0001] The utility model relates to the technical field of emulsion collectors, and specifically relates to an emulsion collector. Background Art

[0002] During lactation, lactating women generally use breast pumps to squeeze out the milk accumulated in the mammary glands. On the one hand, using a breast pump can dredge the mammary glands, avoid the accumulation of excess milk in the mammary glands to form lumps or cause inflammation. On the other hand, it can extract and store the excess milk, which is convenient for breastfeeding infants who cannot suck the milk. Common breast pumps suck breast milk in the breast through negative pressure. During the sucking process, the discomfort of the mother is less, and the problem of breast engorgement is reduced. At the same time, the sucked milk can be stored for convenient feeding. During the breastfeeding process, lactating women will have a situation of reflexive lactation. When one breast is stimulated, the mammary gland cells of this breast are stimulated and start to produce milk. This stimulation will be transmitted to the mammary glands on the opposite side through the nervous system, resulting in a similar reaction in the opposite breast.

[0003] The single-sided breast pumps on the market can suck milk from a single breast. During the milk sucking operation, it is necessary to start the negative pressure mechanism to suck air to generate suction. When the breast shield of the breast pump is in close contact with the female breast, a sealed negative pressure space is formed. The breast shield acts on the female breast to suck out the milk, and the milk enters the drainage cavity from the milk suction channel of the fitting cavity of the breast shield and flows out from the milk outlet into the collection container for collection. However, during the milk sucking process of the single-sided breast pump, the other breast will simultaneously exude milk. If it is not processed and collected in time, it will cause waste of milk or the milk will drip onto the clothes, increasing the cleaning steps and bringing inconvenience, thus affecting the user experience.

[0004] In view of the above deficiencies, it is necessary to develop an emulsion collector to supplement and assist the single-sided breast pump, further improve the problem that the milk exuded from the other breast during the milk sucking process of the single-sided breast pump cannot be well collected and utilized, and further meet the user's usage requirements.

[0023] The following will describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0024] Such as Figures 1 to 5An emulsion collector shown in the figure includes a main body 1, the main body 1 is provided with a cavity 11, a first main body opening 2 communicating with the cavity 11, an emulsion collection part 3 communicating with the cavity 11 and fitting with the breast, and a one-way valve 4 communicating with the cavity 11. The emulsion collection part 3 is made of an elastic material. The one-way valve 4 is provided with an air outlet 41 communicating with the outside, and an air inlet 42 communicating with the first main body opening 2 and the air outlet 41 respectively. The one-way valve 4 is used to drive the gas in the cavity 11 to move from the air inlet 42 towards the air outlet 41. Through the cooperation of the emulsion collection part and the one-way valve, the utility model can collect the emulsion oozing from the other breast during the unilateral milk sucking process, reduce waste and inconvenience, and thus improve the user experience. When the breast fits on the elastic emulsion collection part, the emulsion collector forms a collection space, and the gas in the cavity will be driven to move from the air inlet towards the air outlet. After the cavity forms a negative pressure, the breast is tightly attached and pushed to make the emulsion flow from the emulsion collection part into the cavity.

[0025] Specifically, the main body is used to support the overall shape. The elastic emulsion collection part can fit tightly and comfortably on breasts of different shapes and sizes, can avoid emulsion leakage, and reduce the pressure on the breast to effectively collect the overflowing emulsion. When the emulsion collection part fits on the breast, the one-way valve connected to the first main body opening can make the gas move from the air inlet towards the air outlet. The first main body opening forms a channel for air to be discharged to the outside of the cavity, and the emulsion collector forms a negative pressure to attract the emulsion into the cavity. The cavity can store the emulsion oozing from the other breast, thereby assisting in emulsion collection. When the one-way valve is separated from the first main body opening, the first main body opening forms a channel for the emulsion to move to the outside of the cavity. The utility model has a simple structure, is convenient to operate, and is easy to clean and disinfect.

[0026] Certainly, the one-way valve can be an independent component that is separately separated from the first main body opening, or it can be fixed on the main body, which is convenient for the one-way valve to still be connected to the main body after separation, reducing the time spent looking for these small accessories such as the one-way valve.

[0027] Such as Figures 2 to 5An emulsion collector as shown, the check valve 4 is made of an elastic material. The check valve 4 is provided with at least one check valve air outlet part 40, and the air outlet 41 is located on the check valve air outlet part 40. Further, as a preferred embodiment of the present invention rather than a limitation, the air outlet located on the check valve air outlet part can ensure the directional flow of gas under the control of the check valve and quickly and effectively discharge the gas from the cavity, preventing air or impurities from flowing back into the cavity. At the same time, the check valve helps to reduce the pressure loss during the milk sucking process, keep the inner cavity in negative pressure, and improve the suction efficiency. The check valve made of elastic material can adapt to different pressure changes, be more flexible and durable, and ensure that it can still maintain good sealing performance after multiple uses. Elastic materials such as silicone rubber and silica gel can provide resilience to maintain the opening and closing functions of the air outlet, ensuring that the gas only goes out and does not come in.

[0028] Optionally, in some embodiments, when the emulsion secretion amount is large, multiple check valve air outlet parts can evacuate the gas accumulated in the cavity faster, ensuring a continuous and smooth collection process.

[0029] Optionally, in some embodiments, an air pump device can be connected to the check valve air outlet part to further increase the gas discharge volume.

[0030] As Figure 2 An emulsion collector as shown, the cross-section of the check valve air outlet part 40 is triangular or trapezoidal. The outer diameter of the check valve air outlet part 40 near the air inlet 42 is larger than the outer diameter of the check valve air outlet part 40 near the air outlet 41. Further, as a preferred embodiment of the present invention rather than a limitation, for the check valve air outlet part with a trapezoidal or triangular cross-section, since the outer diameter of the check valve air outlet part near the air inlet is larger, with the gradual reduction of the cross-sectional area, a certain acceleration can be naturally formed during the discharge process, which not only helps to quickly empty the gas accumulated in the cavity, but also can reduce gas turbulence and reverse flow. When negative pressure is generated, the larger air inlet area can allow more gas to flow in quickly, and then a stronger negative pressure can be formed in the cavity. The stronger negative pressure can better attract the emulsion into the cavity and improve the emulsion collection efficiency.

[0031] As Figures 2 to 5As shown, an emulsion collector, the check valve 4 is provided with a check valve outer housing 43 located outside the air outlet part 40 of the check valve. A check valve groove 431 is provided between the inner side of the check valve outer housing 43 and the outside of the air outlet part 40 of the check valve. Further, as a preferred embodiment of the present invention rather than a limitation, the check valve outer housing can provide an additional protective layer for the check valve, which can prevent foreign objects from entering the outside, and at the same time enhance the stability and durability of the overall structure. It helps to extend the service life of the check valve and ensure that the check valve assembly is not easily damaged during daily use and cleaning. In addition, the check valve groove can reduce the extrusion force on both sides of the air outlet part of the check valve, avoid the air outlet on the air outlet part of the check valve from not being opened smoothly, and help to form a more stable negative pressure during milk collection, thereby improving the efficiency of emulsion collection.

[0032] As Figures 1 to 5 As shown, an emulsion collector, the check valve outer housing 43 is provided with a check valve lifting part 432 extending outward and a check valve connecting part 433 connected to the main body 1. Further, as a preferred embodiment of the present invention rather than a limitation, when the user needs to clean or maintain, there is no need for complex operations. Only by gently lifting the check valve lifting part extending outward can the connection between the check valve and the main body be separated, improving the user experience. The check valve connecting part connected to the main body ensures that the check valve is firmly and sealedly installed on the main body. During the whole process of collecting emulsion, the check valve can work stably, avoiding air leakage caused by accidental movement of the check valve during use.

[0033] Optionally, in some embodiments, the check valve connecting part can be connected to the main body by bonding, threaded connection, snap connection, mortise and tenon connection, magnetic connection, groove connection, fastener connection, integral molding, hot melting and other methods.

[0034] As Figures 2 to 4An emulsion collector as shown, the emulsion collecting part 3 is provided with an outer fitting end 31, the outer fitting end 31 is provided with a first fitting end inner cavity 311 communicating with the cavity 11, and a first fitting end opening 312 located between the breast and the first fitting end inner cavity 311. The outer fitting end 31 is arranged in a trumpet shape. Further, as a preferred embodiment of the present invention rather than a limitation, the first fitting end opening allows the breast to extend into the first fitting end inner cavity. The trumpet-shaped outer fitting end can better adapt to breasts of different shapes and sizes, can provide a progressive fitting pressure, making the pressure around the nipple relatively light, and the pressure gradually increases as it expands outwards. In this way, it not only ensures good sealing but also reduces the direct compression feeling on the breast, increasing the comfort of use. In addition, the trumpet-shaped outer fitting end also helps to guide the milk flow towards the center, improving the collection efficiency. Specifically, the first fitting end inner cavity communicates with the cavity, ensuring that the emulsion can smoothly flow from the breast through the first fitting end opening into the cavity, without the milk flow being blocked due to too small an opening or the sealing being reduced due to too large an opening. In addition, the trumpet-shaped outer fitting end is easier to clean and maintain, helping to remove residues and impurities.

[0035] As Figures 2 to 4 An emulsion collector as shown, the emulsion collecting part 3 is provided with an areola fitting end 32 located in the first fitting end inner cavity 311 and protruding towards the first fitting end opening 312. The areola fitting end 32 is provided with a second fitting end inner cavity 321 communicating with the first fitting end inner cavity 311, and a second fitting end opening 322 located between the first fitting end inner cavity 311 and the second fitting end inner cavity 321. The areola fitting end 32 is arranged in a trumpet shape. Further, as a preferred embodiment of the present invention rather than a limitation, the trumpet-shaped arrangement of the areola fitting end enables it to adapt to breasts of different sizes and shapes, especially the area around the nipple, providing a tighter fit. Since the trumpet shape of the areola fitting end helps to enclose the area around the nipple, it can reduce the leakage of the emulsion during the milk suction process. The trumpet shape of the areola fitting end may exert less pressure on the breast, thus improving the comfort during use.

[0036] Specifically, the areola fitting end is internally provided with a second fitting end inner cavity communicating with the first fitting end inner cavity. The emulsion can pass through the second fitting end opening from the areola part and directly enter the second fitting end inner cavity, and then flow into the cavity, ensuring the smoothness and efficiency of the emulsion collection path. Due to the tight fit and trumpet-shaped design of the areola fitting end, the emulsion can be sucked into the collector more quickly, reducing the retention time of the emulsion on the breast, thereby improving the overall collection efficiency.

[0037] As Figure 2A milk collection device as shown. There is a deformation gap 310 between the outer side of the second fitting end opening 322 and the inner wall of the inner cavity 311 of the first fitting end. On the side of the areola fitting end 32 away from the second fitting end opening 322, there is an extension 323 extending towards the cavity 11, and the cross-section of the extension 323 is arc-shaped. Further, as a preferred embodiment of the present invention rather than a limitation, the setting of the deformation gap allows the areola fitting end to have a certain deformation space when fitting the breast, so as to better adapt to areolas of different shapes and sizes, ensuring that the milk collection device can closely fit the breast and reducing the overflow of milk. Due to the existence of the deformation gap, when the milk collection device forms a negative pressure, the areola fitting end can more closely fit the breast, thereby enhancing the negative pressure effect and contributing to more efficient milk collection and improved collection efficiency.

[0038] Specifically, the design of the extension of the areola fitting end enables milk to flow more smoothly from the areola into the inner cavity of the second fitting end, and then into the cavity through the inner cavity of the first fitting end. The flow path reduces the resistance and residence time of milk during the collection process, improving the collection efficiency. The outer diameter of the extension is slightly larger than the outer diameter of the inner cavity of the second fitting end, and the lower side of the extension has a downward inclination angle, so that when milk drips into the inner cavity of the second fitting end, it has a tendency to move downward. The arc-shaped cross-section of the extension helps prevent the accumulation of milk in the areola fitting end, reduces the possibility of bacterial growth, and also enhances the structural strength of the areola fitting end, providing sufficient support for the areola fitting end to enable the deformation gap to deform, and avoiding the entire areola fitting end from collapsing and failing to tightly fit the areola after the areola fitting end is attached to the areola.

[0039] As Figures 1 to 5 A milk collection device as shown. There are reinforcing ribs 3121 on the outer peripheral side of the first fitting end opening 312. The projection of the first fitting end opening 312 is petal-shaped. The reinforcing ribs 3121 extend from the edge of the first fitting end opening 312 towards the cavity 11. There are multiple reinforcing ribs 3121 and they are formed in a wave shape to enclose the outer periphery of the first fitting end opening 312 along the circumferential direction. Further, as a preferred embodiment of the present invention rather than a limitation, setting the reinforcing ribs on the outer peripheral side of the first fitting end opening can significantly enhance the structural strength and stability of the outer peripheral side of the first fitting end opening. Especially when used for a long time or under the action of slight external force, it can maintain the sealing performance of the first fitting end opening, contribute to reducing the entry of air, enhancing the negative pressure effect, and thus improving the collection efficiency of milk.

[0040] Specifically, the first fitting end opening is designed in a petal shape. Besides being aesthetically pleasing, this non-linear edge can better conform to the natural contour of the breast, reducing the direct pressure on the skin and increasing the comfort of the user. The petal shape also helps to disperse pressure, making the force around the nipple more evenly distributed. The reinforcing rib is formed in a wave shape along the outer circumference of the first fitting end opening, which not only increases the visual beauty of the product but also provides additional elastic space to adapt to the minor changes of the breast during the process of collecting milk. At the same time, the wave-shaped reinforcing rib can more gently conform to the skin when stretching and retracting, further enhancing the comfort level.

[0041] As Figures 1 to 5 shown in a milk collector, an arc surface 12 is provided on one side of the main body 1 away from the milk collection part 3, and a platform surface 13 is provided on one side of the main body 1 close to the milk collection part 3. The maximum outer diameter of the platform surface 13 is greater than or equal to the outer diameter of the first fitting end opening 312. The first opening 2 of the main body is located on the upper side of the main body 1, and a step portion 121 is provided on the arc surface 12. Further, as a preferred embodiment of the present invention rather than a limitation, the design of the arc surface on the side of the main body away from the milk collection part, especially the part in contact with the user's palm during use, can provide higher comfort and reduce the fatigue during long-term use. The design of the platform surface ensures the stability between the main body and the milk collection part. When the maximum outer diameter of the platform surface is greater than or equal to the outer diameter of the first fitting end opening, it helps to support and stabilize the milk collection part, ensuring that the milk collection part fits more closely to the breast during milk collection, reducing milk leakage, and at the same time providing better physical support for the user, making the milk suction process smoother and reducing the risk of milk leakage or incomplete collection caused by shaking or improper operation during use.

[0042] Specifically, when the first opening of the main body is located on the upper side, it enables the user to hold it more easily and observe and operate the milk collector more conveniently, facilitating the natural flow of milk under the action of gravity, allowing the milk to flow smoothly into the collection container, and at the same time reducing the frequency of posture adjustment by the user during use, making the whole process of collecting milk more relaxed and comfortable. Meanwhile, the step surface can better facilitate holding, increase the contact area, and prevent the arc surface from being too smooth to hold.
