There is evidence that breastfeeding is protective against asthma in early childhood. Compared to the children who were not breastfed, those who were breastfed for at least 4 months had vital capacities that were larger than those who were not breastfed, after adjusting for birth weight, sex, and current height and weight (p = 0.008). In addition to bioactive factors transferred to the infant in breast milk, another potential explanation for these associations is the mechanical stimulus due to prolonged suckling at the breast that results in improved mechanics of ventilation in breast fed children compared to bottle-fed infants.


Invention Description:


The subject invention is a nursing bottle that includes a piston diaphragm configured to generate negative pressure within a portion of the interior of the body.




This invention should be used to bottle-feed infants as opposed to traditional nursing bottles.


Advantages and Benefits:


Physical exercise training resulting from suckling at the breast results in increased elasticity and efficiency of children’s lung parenchyma. This also leads to increases in lung capacity and airflow in breastfed children compared to bottle-fed children. Differentials in the pressure generated between breastfed verses bottle fed infants have been noted by previous researchers, with findings of up to a three-fold higher negative pressure due to breastfeeding. Thus, at least some of the benefits of breastfeeding may be lost when mothers practice “indirect” breastfeeding (i.e. pumping and bottle feeding their infants) compared to direct suckling at the breast.


When direct breastfeeding is not possible, the benefit conferred by direct suckling may be (partly) achieved by the use of modified feeding bottles that would mimic natural direct breastfeeding. Thus, in order to promote normal lung growth and development, an artificial increase of flow “resistance” from infant feeding bottles may prove beneficial. Such a device is of increasing significance to improve respiratory health, since approximately 75% of the mothers in the United States pump and bottle feed their children, in particular after one month of lactation.
