The present invention further relates to a pump device (47) and a breast pump device (41) including a valve (1) as described above.

An expression kit (2) for use in a breast pump device (1) for extracting breast milk from a human breast comprises a breast pump body (20) having a first pressure chamber (21), a second pressure chamber (22), and a membrane portion (5) separating the first and the second pressure chamber (21, 22) from each other. The membrane portion (5) is configured to form a barrier between the first and the second pressure chamber (21, 22) for preventing leakage of human breast milk from the second pressure chamber (22) to the first pressure chamber (21), yet to allow for air exchange between the first and the second pressure chamber (21, 22), wherein the membrane portion (5) is hydrophobic and has the shape of a solid sheet being provided with holes (50) which are configured for rendering the sheet permeable to air and impermeable to liquid.

The invention discloses a hospital grade breast pump device with a wide negative pressure range. The hospital grade breast pump device comprises a chassis, a stepping motor, an air chamber sliding cylinder, a crank, a rocking lever, a piston, a milk collecting bottle and a cup, wherein one end of the crank is in fixed transmission and connection with a rotating shaft of the stepping motor, the front end of the air chamber sliding cylinder is connected with the chassis through a support shaft, and the air chamber sliding cylinder can rotate around the support shaft; one end of the rocking lever is movably connected with the other end of the crank, the other end of the rocking lever is fixedly connected with the piston, and the piston is arranged in the air chamber sliding cylinder and movably and hermetically connected with the air chamber sliding cylinder; and a suction pipe joint is arranged at the front end of the air chamber sliding cylinder, the suction pipe joint is connected with the milk collecting bottle through a flexible pipe, the milk collecting bottle is further connected with the cup through the flexible pipe, and an exhaust hole is formed in the back part of the air chamber sliding cylinder. The hospital grade breast pump device with the wide negative pressure range, disclosed by the invention, effectively expands the negative pressure regulation range, the range can achieve -100mH-300mmHg, the negative pressure regulation at any level can be realized in the negative pressure range, and the hospital grade breast pump device can completely simulate the processes of sucking, stopping and releasing when a baby sucks breast milk.

Biological samples of mammary fluid or components thereof are obtained using a breast pump device coupled with an absorbent paper or membrane, optionally facilitated by administering oxytocin to the subject. The breast pump device stimulates expression of mammary fluid and provides for collection of diagnostic samples on the absorbent paper or membrane to evaluate breast disease, including cancer. The biological sample may include fluid containing one or more of cells or cellular components, proteins, glycoproteins, peptides, nucleotides or other desired constituents comprising a breast disease marker. Absorbent paper or membrane, and methods relating to the paper or membrane, and a breast pump device are also provided.

The invention discloses a breast pump and a driving control device for the breast pump, the device comprises an air pump module, an air valve module and a control module, the breast pump comprises a breast pumping part, and the breast pumping part is used for covering a breast to form a closed space; wherein the control module is used for controlling the air pump module to exhaust air in the closed space within a first time interval so as to realize an air exhaust period; the control module is used for controlling the air valve module to release air from the closed space within a second time interval so as to realize an air release period, and one air exhaust period and one air release period form a simulated sucking period; and the control module is also used for controlling the operation of the air pump module or the air valve module in the simulated sucking period so as to enable the milk sucking component to generate vibration. According to the drive control device for the breast pump and the breast pump, the vibration massage effect in the breast pumping process can be achieved, and the user experience is improved.

The invention provides a breast pumping device for performing breast pumping treatment while massaging breasts of a puerpera. A connecting belt is fixedly mounted between every two adjacent breast pumping hoods; the front surfaces of the breast pumping hoods are fixedly connected with a three-way guide pipe; fixing devices are fixedly installed on the sides of the two breast pumping hoods; the outer end of the three-way guide pipe is fixedly connected with an extraction assembly; a milk storage bottle is detachably arranged on the lower surface of the three-way guide pipe and on the left sideof the extraction assembly; lactagogue mechanisms are fixedly connected to the lower parts of the breast pumping hoods; when the breast pumping device is required to be used, based on adaptive temperature, hot water is poured into a heat preservation container; the heat preservation container can convey internal hot air into air bags through connecting pipes, the air bags expand due to heat and contract due to cold, protrusions on the surface of the air bags extrude and massage the breasts, the effect of stimulating the breasts through hot compress is achieved, the milk pumping process is smoother, and latex pads and the sealing hoods are designed to be more attached to the skin of the human body.
