Abstract
The utility model provides an electric heating wax pad used in the treatment of keritherapy, belonging to a medical care article. The electric heating wax pad is mainly composed of a cloth pad 1 immersed with paraffin wax, and electric heating wires 2 arranged in the cloth pad 1. The electric heating wax pad has the advantages of simple structure, reasonable design, low cost, and convenient operation, etc. When used, the utility model does not need to be provided with a special wax pad heater to heat the wax pad, but the wax pad can be directly heated by the electric heating wires 2, so that the utility model brings convenience for treating patients.
Description
This utility model relates to a kind of medical health care products, particularly a kind of in keritherapy employed wax pad.
Wax therapy is to utilize the warm character of paraffin, and the paraffin of heating is directly applied a kind of physical therapy method on the human body skin surface.Because human body skin will be compared the toleration height of other heat transfer medium to the warm toleration of paraffin, particularly when the oils and fats in the paraffin and its cooled and solidified to the compression of skin, make the warm deep tissue that can reach skin, strengthened the warm-heat effect of paraffin, thereby some diseases such as rheumatism, wound recovery, all kinds of inflammation have been produced special curative effect.
At present, people's common employed method when carrying out wax therapy is with wax pad and the supporting use of wax pad heater, and the cloth pad that is soaked with paraffin is heated in the wax pad heater of special use, treats when reaching to take out to apply in the affected part of human body after temperature required.Its major defect is that wax pad heater is bulky, and complex structure costs an arm and a leg, and every cover price is up to 20,000 yuans.And the energy consumption height, operate loaded down with trivial details, the treatment cost also high, the patient can only treat at the large hospital with this wax pad heater, cures the disease to the patient and brings a lot of troubles.
The purpose of this utility model is to provide a kind of Electric heating wax pad that heating wire is housed in being soaked with the cloth pad of paraffin.Make that can be equipped with special-purpose wax pad heater in the wax therapy process heats the wax pad, the wax pad can bring convenience for patient's treatment by the heating wire direct heating of self.
The purpose of this utility model is achieved in that in being soaked with the cloth pad of paraffin heating wire is housed.
For the temperature that makes the wax pad can automatically be controlled in the selected scope of people, two of heating wire is terminated on the temperature controller, and the temperature sensor in the temperature controller is placed in the cloth pad.
Temperature controller of the present utility model mainly is by mains transformer, bridge rectifier, and by the voltage comparator that temperature sensor, resistance, adjustable potentiometer and operational amplifier constitute, audion, relay is connected in sequence.
The utlity model has advantages such as simple in structure, reasonable in design, cheap, easy to use.Simultaneously in use can be as required the temperature of wax pad be controlled in certain scope, has the characteristics of automatic constant-temperature control, bring great convenience to the patient.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the circuit theory diagrams of temperature controller in this utility model.
As shown in Figure 1, in being soaked with the cloth pad 1 of paraffin heating wire 2 is housed, two of heating wire 2 terminates on the temperature controller 4, and the temperature sensor in the temperature controller 43 is placed in the cloth pad 1.On temperature controller 4, be connected to temperature adjustment knob 6 that is used for attemperation and the plug 5 that is used for energized.
As shown in Figure 2, temperature controller 4 is by mains transformer B, and bridge rectifier is by critesistor R
t(being equivalent to the temperature sensor 3 among Fig. 1), resistance R
7, R
6, adjustable potentiometer W
1(being equivalent to the temperature adjustment knob 6 among Fig. 1) and operational amplifier IC
1The voltage comparator that constitutes, audion, relay J is connected in sequence.Resistance R (being equivalent to the heating wire 2 among Fig. 1) and normal opened contact J series connection are on power supply.When the temperature of wax pad rises, critesistor R
tResistance constantly descend operational amplifier IC along with the rising of temperature
1"+" foot current potential descend thereupon, when "+" foot current potential is lower than "-" foot current potential, operational amplifier IC
1Output pin become electronegative potential, audion Q
1End, the relay J outage, normal opened contact J disconnects, and the resistance R outage stops heating to the wax pad.When wax pad temperature descends, critesistor R
tResistance descend with temperature and increase operational amplifier IC
1"+" foot current potential constantly raise, as operational amplifier IC
1"+" foot position rise to when being higher than "-" foot current potential operational amplifier IC
1Output pin output positive voltage, audion Q
1Conducting, relay J gets electric, normal opened contact J adhesive, resistance R gets and electric the wax pad is heated.Above process is gone round and begun again, and the wax pad is remained in the treatment temperature range of requirement, has the characteristics of automatic constant-temperature control.Can also pass through regulator potentiometer W in addition
1Change the control temperature of wax pad.
