Description

Water bath massager for newborn

Technical Field

The utility model relates to the technical field of medical massage, in particular to a water bath massager for newborns used in line maintenance.

Background

With the continuous research of the neonatology department, the survival rate of neonates in an intensive care unit is remarkably improved, but the feeding problem becomes a major problem in clinic at present. The gastrointestinal function of the neonate is immature, the situation of feeding intolerance and the like easily occurs in the feeding process, the development of the neonate is influenced, at present, the neonate is nursed through a retained stomach tube and parenteral nutrition in clinic, but the problem of early nutrition of the neonate is only solved, and various measures are still needed to solve the feeding problem of the whole nursing process of the neonate. In China, a plurality of documents indicate that the abdominal massage can effectively stimulate abdominal receptors, improve the excitability of a nervous system and have a remarkable effect on improving the gastrointestinal function of a newborn.

Although the existing abdomen massage instruments for adults are various, no abdomen massage instrument related to newborns exists, and the probability of intestinal flatulence is particularly high due to the fact that intestinal nerve cells of the newborns are not well developed, so that the newborns need to massage the abdomen to relieve the intestinal flatulence more than the adults, and the record of the abdomen massage instrument for the newborns does not exist in all documents and patents, so that the design of the abdomen massage instrument for the newborns is particularly important. The breathing mode of the neonate is abdominal breathing, and the neonate abdomen is more fragile than an adult, and has stricter requirements on the weight of the instrument, the massage strength and the heating temperature.

The reason why no neonate massage apparatus is available on the market is analyzed as follows:

1. the breathing mode of the neonate is abdominal breathing, and the neonate abdomen is more fragile than an adult, and has stricter requirements on the weight of the instrument, the massage mode, the force and the heating temperature.

2. The newborn infant is different from the adult massager in structure because it is not umbilical-cord-off and the position of the umbilical cord needs to be left in the structure of the massager.

3. The resistance of the neonate is very weak and it is inconvenient to thoroughly sterilize the instrument, which increases the risk of infection of the neonate.
