Patient burns；Pressure difference is greater than twice of filter cabinet at the gas inlet and outlet that pressure difference switch 17 detects filter box-body 6
When 6 initial resistance of body, 6 internal resistance of filter box-body is excessive, illustrates that filter paper 7 blocks seriously, and pressure difference switch 17 exports closure signal, this
Alarm indicator light 19 lights, and medical worker is prompted to replace filter box-body 6.
Therefore, the utility model passes through setting heater housing 2, silicon rubber heating plate 3, temperature sensor 16, number temperature
Controller 11, A.C. contactor 13 and temperature protector 16 are spent, the regulation button 14 on operation digital temperature control 11 is passed through
Set temperature controls the carbon dioxide gas temperature for inputting abdominal cavity between 37 ~ 42 DEG C, realizes temperature-controllable, reduces in art
Blood loss avoids the postoperative generation hypothermia of patient, and postoperative function of intestinal canal is promoted to restore, and shortens the hospital stays；It is filtered by setting
Device cabinet 6 is placed in filter box-body 6 and folds the wavy composition filter of filter paper 7, can be to the titanium dioxide for entering human body
Carbon gas is filtered, and reduces patient's infection rate after abortion operation.In addition, the utility model is super by being arranged in silicon rubber heating plate 3
Warm protector 15, when 3 surface temperature of silicon rubber heating plate reaches 80 DEG C, Overtemp. protector 15 exports cut-off signal, stopping pair
Silicon rubber heating plate 3 heats, to avoid causing patient to burn because gas temperature is excessively high；Pass through setting pressure difference switch 17, centre
Relay 18 and alarm lamp 19, for pressure difference switch by pressure at detection 6 gas inlet and outlet of filter box-body, measurement gas is logical
Resistance is crossed, to judge whether filter paper 7 blocks, if need replacing filter box-body 6, relative to disposable filter, save
Medical treatment cost.
The embodiment of the above, the only preferred embodiment of the utility model are only used to explain that this is practical new
Type, not limiting the utility model practical range to those of ordinary skill in the art certainly can be according to this specification
Disclosed in technology contents, make other embodiments easily by way of replacing or changing, therefore all practical new at this
Made changes and improvements etc. in the principle of type, should be included in present utility model application the scope of the patents.
