Breast pump

Breast pump is a device for dedusting of milk in lactating women. Arranged by the principle of role models physiological act of sucking breast. Breast pump operates through intermittent negative pressure in the lining of the breast pump, tight to the areola breast cancer. There are several types of breast pumps.

The most common and simple design of the pumps is breast pump Chernetskogo, consisting of plates with the tank and rubber cylinder (Fig. 1). The disadvantages of this pump is the possibility of impaired blood and lymph circulation in tissues, cracking nipples, as the power vacuum created by a rubber balloon, exceeds the average power (180-200 mm RT. century), developing sucking breast; getting milk in the container during pumping can cause milk contamination and infection of the nipple for subsequent use of the pump. Breast pump system Dyatlova (Fig. 3) not have these disadvantages and are more comfortable in them the negative pressure created by vacuum pump, using vacuum breaker is replaced positive pressure by zassa atmospheric air. The air coming into the pad and the receptor, filtered through a ball of wool (gauze), enclosed in a glass (metal) ampoule. The device lining excludes milk per unit, while pumping. In these pumps is provided by regulation gradual rarefaction of the air in the lining of the vacuum regulation, which is especially important when nipple cracks. There are electric, electrovozostroenie, water jet, and manual breast pumps of this type. The most commonly used manual breast pump with rubber cylinder (Fig. 2). He simply arranged, cheap and convenient to use at home. Rubber balloon is used to rarefaction of the air in the pump and replace the vacuum breaker. Periodic compression and smoothing of the container up to 30 times in 1 min. provides rhythmic sucking milk. The compression ratio and the unfolding of the container determines the strength sucking milk.
Breast pump used in the engorgement of the mammary glands, in excess of milk, irregular shape nipples, complicating the act of sucking (flat involved, small, split, rough), as well as deep bleeding cracked nipples beginning mastitis.
Indications for use of a breast pump from the child: malformations (cleft lip, cleft palate), prematurity, the weakness of the newborn, inflammatory diseases of the mouth and nose (rhinitis, stomatitis), the number of severe disease (pneumonia, sepsis, intracranial injury).
