Because of change in woman’s place in society, the number of working woman is growing and the demand of the breast pump is increasing as well. Commercial product of the breast pump is applying only negative pressure for sucking and many users feel a pain for a long term use. While a baby is using peristaltic motion as the result of tongue and jaw action in addition to suction. In this research, therefore the breast pump with a baby-like motion is developed. In order to realize baby-like peristaltic motion, cam mechanism is applied. Also for producing negative pressure, crank mechanism is utilized. As the result, it turns out that the breast pump developed is realized the same peristaltic motion and suction pattern as a baby.This paper is the full translation from the transactions of JSME Vol.73, No.730.

Introduction During the Coronavirus Disease 2019 global pandemic, maternal and newborn wellbeing has received much attention. Detailed reports of infected women breastfeeding their infants are uncommon. Due to incomplete information available, full data about those infants’ outcomes are lacking, and evidence of infectivity through breastfeeding has not been documented. Main Issue Here, we report about a mother who breastfed her infant until she was confirmed with the SARS-Cov-2 infection. After follow-up, we have confirmed that the infant, who was breastfed by the infected mother, was not infected. Methods A 33-year-old woman gave birth to a full-term male infant on November 8, 2019. Since birth, she had been exclusively breastfeeding the baby until she was confirmed with the SARS-Cov-2 infection on February 8, 2020. She was hospitalized, isolated from her baby, and stopped breastfeeding. Even though she remained asymptomatic, her milk was expressed using a breast pump and discarded. The mother’s milk sample was collected on February 9, 2020, and the result of the nucleic acid test for COVID-19 was negative. Her infant was asymptomatic and remained virus negative. Her laboratory findings and chest Computed Tomography imaging was normal. She was treated according to the national protocol with aerosolized interferon α2β, lopinavir/ritonavir and ribavirin. Her serum SARS-CoV-2 specific antibodies(IgG and IgM) tested positive when discharged. She returned to breastfeeding after discharge. Conclusion Our findings suggest that breastfeeding may be less of a risk than anticipated. Additional research is needed to explore this possibility.

In the present investigation, problem of heat transfer has been studied during peristaltic motion of a viscous incompressible fluid for two-dimensional nonuniform channel with permeable walls under long wavelength and low Reynolds number approximation. Expressions for pressure, friction force, and temperature are obtained. The effects of different parameters on pressure, friction force, and temperature have been discussed through graphs.

A nonprofit voluntary community hospital, the Hunterdon Medical Center, has made a commitment to encourage breast-feeding among employees. In support of this commitment, arrangements were made for time off during the work day for nursing mothers to pump their breasts. An electric breast pump in a suitably accessible location and supportive professional advice were offered. Among those who chose to nurse their babies, it was found that mothers nursed for longer times and were more likely to continue nursing after return to employment when this program was available.
