Description

Intelligent pressure sensor controlled breast pump

Technical field

The invention relates to the technical field of maternal and infant products, and in particular to an intelligent pressure-sensing control breast pump.

Background technique

Breast pumps can be used by nursing women in the hospital or at home to pump breast milk from the breasts. Congestion symptoms can be relieved after using a breast pump to express milk. If you have mastitis, you can use a breast pump to remove breast milk from the infected breast to assist in the treatment process. Breast pumps can relieve sore and chapped nipples and expose flat or inverted nipples. In addition, breast pumps also allow mothers to provide a way for babies with sucking problems, cleft lip and palate, or premature babies to enjoy breastfeeding.

Today's electric breast pump control boards mainly use MCU control technology and use 3.7V lithium batteries or 5V power adapters to provide power. The main control chip controls the working and stopping time of the vacuum pump and solenoid valve to imitate the function of baby sucking milk and promoting lactation. The human-machine interface is an LCD screen/nixie tube/LED display, and the power on/off, working mode selection and gear adjustment are realized through induction buttons/mechanical buttons.

Breast pumps currently on the market generally do not have pressure sensing, and the suction value is controlled by the MCU controlling the vacuum pump's evacuation time. This design method will cause the suction value to fluctuate in a large range and be inaccurate, which will affect the mother. Breastfeeding experience. Moreover, there is no suction sensor, so it is impossible to perform accurate pressure maintaining settings. The pressure can only be maintained within a large suction fluctuation range. This may occur. When maintaining pressure at the lower limit of suction, the suction force is small and milk cannot be sucked out, which affects suction. Breast efficiency: When maintaining pressure at the upper limit of the suction force, the suction force is large, which may damage the breast glands, cause pain during sucking, and affect the mother's sucking experience. There is no suction sensor, the suction value cannot be detected, and the real-time suction value cannot be displayed on the display interface. There is no suction sensor, so it cannot intelligently sense whether the mother is pumping breasts unilaterally or bilaterally. It cannot intelligently and dynamically adjust the stable breast pumping intensity. It can only use a fixed single-sided breast pumping mode or a double-sided breast pumping mode. If the unilateral mode is used for bilateral breast pumping, the suction force will be too small and breast milk cannot be sucked out; if the bilateral mode is used for unilateral breast pumping, the suction force will be too high and the breasts may be damaged. It is impossible to perform a stable breast pumping process. After the battery is low, the suction power is controlled by controlling the vacuum time. Therefore, after the battery is low, the suction power will be reduced when the vacuum is used for the same time.

This embodiment intelligently identifies whether the mother uses unilateral or bilateral breast pumping, thereby adjusting the unilateral or bilateral breast pumping intensity in real time, accurately, and dynamically. At the same time, you can also set a constant pressure breast-sucking method based on suction induction, and simulate the baby's fast and powerful sucking method (including but not limited to the following 3 methods)

As shown in Figure 5, the breast pump monitors the suction value in real time through the built-in pressure sensor. For the mother's different breast pumping methods (unilateral or bilateral breast pumping), it monitors changes in the suction value and intelligently switches to one side. Breast pumping mode or bilateral pumping mode.

As shown in Figure 6, the constant pressure breast pumping method is used, and the built-in pressure sensor monitors the suction value in real time. When the vacuum pump 13 starts to work and performs vacuuming, the set ideal suction value is reached after a short period of time, and the suction value will be maintained at this time. In a constant state, the stability is good and the error is small. After the pressure holding time is up, the solenoid valve 12 will open to connect the air, the suction value will decrease, and then the cycle will continue. Multiple different holding times can be set according to the needs of different mothers. This can not only improve the efficiency of breast pumping, but also improve the mother's comfort and sense of using the breast pump.

As shown in Figure 7, the baby's fast and powerful sucking when sucking out breast milk is simulated. The built-in pressure sensor monitors the suction value in real time. The vacuum pump 13 starts to work and performs vacuuming. After a short period of time, the set ideal suction value is reached. At this time, the main control MCU controls the vacuum pump 13 to stop working and maintain pressure. After a short period of time, the solenoid valve 12 is controlled to work, the valve is opened to release air, but it is not completely released. After the suction power drops to a certain level, the seal is immediately closed, and then the vacuum pump 13 is controlled to work again to vacuum to reach the set suction value. By doing this in a small cycle, the number of cycles can be set according to different mothers’ experience. After the small cycle is completed, the solenoid valve 12 will be completely deflated and the suction value will drop to 0, which is regarded as a large cycle at this time.
