Compared with prior art, the beneficial effects of the utility model are:

1) adopt power supply 12V, prevent the leakage electric shock, can directly use vehicle power, facilitate the saturating patient of abdomen to go aboard for visit parent's tourism outward.

2) increased clock display, increased by 6 groups regularly, conveniently changed dressings on time.

3) Automatic-heating before the prerequisite of changing dressings regularly as required reaches the temperature automatic constant-temperature that needs.

4) out-of-date auto-breaking, energy saving increases product serviceable life.

5) the automatic Memory function is arranged, once set permanent the use, do not need to reset at every turn.
