A sensor system is for sensing the start of milk expression into a collection vessel when using a breast pump device. A sensor is used to provide a signal indicating the presence of the first milk expressed, for use in controlling the breast pump to switch from a stimulation mode to an expression mode. The sensor detects a change in the reflectance of the base of the collection vessel to the electromagnetic radiation used by the sensor.

A breast pump control method is provided. A breast shield is provided with a first cavity. The first cavity is allowed to fit and at least partially accommodate a breast to form a sealed area. A flexible component is provided. The flexible component is provided with a first magnetic component. At least a portion of the flexible component is communicated with the sealed area to form a portion of a wall of the sealed area. A second magnetic component is arranged opposite to the first magnetic component. The first magnetic component is driven by the second magnetic component to move to drive the flexible component to deform, such that a negative pressure is generated in the sealed area to drive the breast to express milk from the breast. A breast pump circuit control system and method are also provided.

The present invention is directed to a method of determining a strategic expression regime for a pump-dependent mother that optimizes the mother's milk production while minimizing the demands on the mother. The regime takes into account the impact of the interval between breast expressions on milk yield for individual breasts within the mother.

A pump body of a breast pump includes an air pump, a battery, a valve, and a neck-hanging structure. A first accommodation housing and a second accommodation housing are provided at two ends of the neck-hanging structure respectively. One of the air pump and the battery is provided in the first accommodation housing, and the other of the air pump and the battery is provided in the second accommodation housing. At least one of the first accommodation housing and the second accommodation housing is provided with an air vent for communicating with the air pump. In the above pump body of the breast pump, the neck-hanging structure is provided, and the first accommodation housing and the second accommodation housing are provided at two ends of the neck-hanging structure. The pump body is supported by the neck-hanging structure, which frees hands and facilitates carrying.

There is provided a method of measuring liquid volume in a sealed container of a breast pump of known volume comprising liquid and gas. The method includes a measurement phase, measuring the volume of gas in the container by changing a first parameter of the gas by a known amount. The method also includes measuring a change in a second parameter of the gas; calculating the volume of gas in the container using the measured change and a predetermined operation equation; and determining the volume of liquid in the container based on the calculation.

A connector includes a connecting barrel with a front opening and a rear opening opposite to each other, a periphery of the rear opening extends outward to form a rear chamber, the connecting barrel is in communication with the rear chamber, a bottom surface of the connecting barrel is provided with a first through-hole, and the rear chamber is provided with a second through-hole.

Provided are a three-way connecting assembly and a wearable breast pump. The three-way connecting assembly includes a three-way connector and an elastic valve plate. The three-way connector is provided with a channel, a milk sucking port, a negative pressure port and a milk outlet. The milk sucking port, the negative pressure port and the milk outlet are spaced apart, and each of the milk sucking port, the negative pressure port and the milk outlet is communicated with the channel. The elastic valve plate is connected with the three-way connector and attached to the milk outlet.

A breast-pumping care accessory and a care method are disclosed. The accessory includes a first attaching element, configured to be attached to a breast of a living body when in operation; a second attaching element; a heating element, located between the first attaching element and the second attaching element; a controller, electrically connected to the heating element; and an energy supply element, configured to supply electric energy to the heating element and the controller. The controller is configured to perform a care controlling method including: obtaining a target breast-pumping care mode; obtaining a heating curve based on the target breast-pumping care mode from a curve library and taking the heating curve as a target curve; and controlling the heating element to generate heat based on the target curve. The target breast-pumping care mode includes any one of a pre-pumping care mode, an in-pumping care mode, and a post-pumping care mode.

A breast pump comprises a breast shield, a pressure source for applying a pressure profile to a breast received in the breast shield and an RF signal source for generating RF signals. The RF signals are applied to an electrode arrangement to provide RF heating of the breast. The supply of the RF signals to the electrode arrangement, i.e. the heating, is controlled with timing which depends on the pressure profile. In this way, the heating is provided at times within the pressure profile when the heating function will be most effective, for example at times of maximum under pressure and hence suction of the breast tissue against the breast shield.

A breast pump includes a housing including a first side and a second side. The first side and the second side define a cavity therebetween. The second side includes a concave surface defining a recess. The breast pump also includes a breast cup for engaging at least a portion of a breast including a nipple and an area surrounding the nipple. The breast cup is attached to the second side of the housing and positioned at least partly within the recess defined by the concave surface. The breast pump further includes a vacuum pump assembly, a container, a heater mounted to the housing, and a power source. The heater extends along the concave surface of the second side of the housing in thermal connection with the breast cup. The heater is configured to provide heat to the breast cup when the power source provides electrical current to the heater.
