Description

  The present invention relates to a milk heating apparatus used in a maternity hospital, a hospital, etc. where a large number of infants are kept.

  In recent years, the importance of environmental maintenance for infants related to the social problem of declining birthrate has been recognized, and as part of this, there has been a great interest in safety and hygiene in the process of childbirth and childcare. In particular, milk feeding for infants is a burdensome work that requires great care at sites where many infants are left, such as maternity hospitals and hospitals.

  Conventionally, in general, in many sites, when nursing milk is warmed or kept warm, the actual condition in terms of hygiene is left to the personal intuition and experience of the person in charge of childcare, or to the manual in the hospital. These do not necessarily have sufficient stability and reliability, and have many variations.

When nursing a large number of infants, baby bottles, nipples, and other tools used as basic work should be cleaned and disinfected and stored at the appropriate temperature in hot water at the time of milk preparation. In some cases, the product is stored at 5 ° C. to 10 ° C. in a temporary refrigerator or the like, and is breast-fed at a suitable temperature, for example, the temperature of human skin, with a water bath when feeding. Heating many baby bottles with a hot water bath at the same time is not suitable for handling because milk sometimes leaks and becomes dirty and unsanitary, and water adheres to the baby bottles.
A newborn medical forum or the like by doctors and hygiene personnel is held for such problems (for example, see Non-Patent Document 1).

In such forums, for example,
(A) Bacteria environmental culture was taken as part of the hospital infection countermeasures. Baumanni, Pseudomonas aeruginosa, K. pneumoniae has been identified.

  (B) The former warm milk device was discontinued for the purpose of infection control. At present, a stainless steel bat is placed on a hot plate, and a hot water bath is used to heat breast milk and milk. The used bat is washed and dried each time. In addition, when a baby or the like who has started oral thawing milk on a temporary basis or warming milk, a container is placed in a sink of a special sink and heated with running water (hot water). However, in addition to the vagueness of temperature management when heating, it cannot be said to be hygienic.

  (C) Speaking from the water + temperature environment, the “milk warmer that favors Pseudomonas aeruginosa, Legionella, etc.” is used every day, so that the baby bottle is heated in contaminated water. When it is absolutely necessary to use a milk warmer, it is necessary to prepare several units, limit the continuous use of one unit to about 24 to 48 hours, and use it with a disinfection and drying time of 2 to 3 days or more.

  (D) When the baby bottle taken out from the milk warmer was sterilized with ozone water before feeding, the bacteria detection rate decreased.

(E) It is uncertain how far it will be effective to apply hot water only to the lower side of the hot milking apparatus (the lower side of the wire mesh) because the steam adheres to the milk bottle.
Such problems have been pointed out.
