Technical Field
[0001] This utility model relates to the field of breast pump technology, and in particular to a wearable three-way breast pump. Background Technology
[0002] A breast pump is a tool used to express breast milk that has accumulated in the mammary glands. Breast pumps are generally divided into manual breast pumps and electric breast pumps. Electric breast pumps have higher milk extraction efficiency, can adjust different milk extraction modes and intensity, simulate the sucking rhythm of a baby, and are more comfortable and convenient to use.
[0003] The main components of a breast pump consist of a bottle, a T-joint, and a negative pressure device. The T-joint typically has three connectors, which connect to the breast shield, the bottle, and the negative pressure device. The breast shield is attached to the breast, and the negative pressure device creates a negative pressure environment inside the T-joint, drawing milk from the breast shield and storing it in the bottle.

[0018] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0019] Example 1:
[0020] like Figure 1-3 As shown:
[0021] In existing technology, breast pumps need to be attached to the milk-expressing area of the breast and secured with a bra. This operation causes the breast pump to compress the breast; at the same time, the narrow bell-shaped cap of the breast pump further compresses the breast, resulting in a poor user experience.
[0022] To avoid direct pressure on the breast from the breast pump, this utility model provides a wearable three-way breast pump, including a breast pump body; the breast pump body includes a flared cap 1, an inlet channel 11, a milk storage structure 12, and a negative pressure device 13; the inlet channel 11 has a connected inlet and outlet at its front and rear ends, respectively; the flared cap 1 is installed on the circumferential side of the inlet of the inlet of the inlet channel 11; the milk storage structure 12 is connected to the outlet of the inlet channel 11; a negative pressure port is opened on the side wall of the inlet channel 11; the negative pressure end of the negative pressure device 13 is connected to the negative pressure port of the inlet channel 11; it also includes a breast suction shield; the breast suction shield includes a breast suction ring 2 for covering the breast and a breast pump for connecting to the breast pump. The breast pumping channel 3 of the main body; the breast pumping ring cover 2 is a funnel-shaped ring-shaped sheet structure; in the direction of breast milk inlet, a first cover opening 21 and a second cover opening 22 are formed on both sides of the breast pumping ring cover 2; the first cover opening 21 is located on the side facing the breast; the second cover opening 22 is located on the side away from the breast; the diameter of the first cover opening 21 is larger than the diameter of the second cover opening 22; the diameter of the second cover opening 22 is not smaller than the outer diameter of the breast pumping channel 3; the two ends of the breast pumping channel 3 are respectively provided with a first opening 31 and a second opening 32 that are connected; the first opening 31 is sealed and connected to the second cover opening 22; the second opening 32 passes through the funnel cover 1 and is sealed and connected to the inlet of the liquid inlet channel 11.
[0023] When using the wearable three-way breast pump provided by this utility model, firstly, the first opening 21 of the breast pump ring 2 is attached to the breast. Then, a matching breast pump bra is worn. The opening of the breast pump bra is only large enough to pass through the breast pump channel 3. The breast pump channel 3 is passed through the opening of the breast pump bra, leaving the breast pump ring 2 inside the breast pump bra. Because the outer contour of the breast pump ring 2 is larger than the outer diameter of the breast pump channel 3, the entire breast pump ring 2 cannot be removed from the opening of the breast pump bra and is thus fixed by the breast pump bra. Then, the breast pump channel 3 exposed from the opening of the breast pump bra is sealed and inserted into the liquid inlet channel 11. Subsequently, the negative pressure device 13 operates. Since the breast pump ring 2 and the breast pump channel 3, and the breast pump channel 3 and the liquid inlet channel 11 are all sealed, the breast milk can be sucked out by the breast pump ring 2. After being sucked out, the breast milk enters the breast pump ring 2, flows through the breast pump channel 3 into the liquid inlet channel 11, and finally enters the milk storage structure 12.
[0024] Because only the breast suction ring 2 is located inside the breast suction bra in the above structure, and the breast suction ring 2 fits the breast contour better and is thinner than the breast pump body, the breast suction bra needs to be tightened less, thereby reducing the pressure on the breast.
[0025] The present invention provides a wearable three-way breast pump that uses a breast pump bra to tighten only the thin breast pump ring 2 to reduce the pressure on the breast, and then connects the breast pump ring 2 to the breast pump body through the breast pump channel 3 to achieve breast pumping, which effectively improves the comfort of use.
[0026] In a preferred embodiment of this invention, the inner diameter of the inlet channel 11 gradually decreases in the direction of milk inflow; the diameter of the second opening 32 is the same as the inner diameter of the inlet of the inlet channel 11. Since the second opening 32 is the same size as the inlet of the inlet channel 11, and the inner diameter of the inlet channel 11 gradually decreases, as the second opening 32 is gradually inserted into the inlet channel 11, it gradually forms an interference fit with the inner wall of the inlet channel 11, ultimately causing the second opening 32 to be firmly locked inside the inlet channel 11, thus fixing the breast pumping channel 3 and achieving a sealed connection with the inlet channel 11.
[0027] The wearable three-way breast pump provided by this utility model achieves tight insertion and fixation of the breast pump channel 3 by interference fit between the breast pump channel 3 and the liquid inlet channel 11, and also has a sealing effect.
[0028] In a preferred embodiment, the side of the first opening 21 facing the breast is covered with an anti-slip layer 23.
[0029] In a preferred embodiment, the anti-slip layer 23 is made of silicone material.
[0030] In a preferred embodiment, the edge of the first opening 21 is provided with a folded edge 24; the folded edge 24 is folded towards the breast pump body. Since the breast pump ring 2 is located inside the breast pump bra during use, in order to better fix the two, an outwardly folded edge 24 is provided on the edge of the first opening 21. The folded edge 24 can be hooked onto the texture inside the breast pump bra, making the breast pump ring 2 more stable.
[0031] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application filed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not claimed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this application are indicated by the appended claims.
[0032] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
