Description
Technical Field
The invention relates to the field of medical instruments, in particular to a multi-capacitance value output capacitance electrode for a short wave therapeutic apparatus and a preparation method thereof.
Background
The current short wave therapeutic apparatus output electrode types are two types: one is a capacitive electrode and the other is an inductive electrode. Usually, an output device of the short wave therapeutic apparatus has two output ports, namely two electrodes need to be connected, and an output signal of the short wave therapeutic apparatus needs to form a tuning loop by using a capacitor or an inductor. Now, capacitance electrodes and two output ends of output equipment of a short wave therapeutic apparatus are described, if two capacitance electrodes are used, as shown in fig. 1, each channel needs to be connected with one electrode, each electrode is composed of an electrode wire and an electrode plate shown in fig. 1, wherein the electrode wire is a tin-plated copper electric conductor with the cross section of 4 square millimeters, metal plates are used inside the electrode plates, when the two electrodes are used simultaneously, because the electrode plates are metal plates, the two metal plates are opposite to each other to form a capacitor, and even when the electrodes are used, the output mode of the short wave therapeutic apparatus is the capacitance electrode output mode.
The difference of the three sets of electrodes is that the areas of the metal plates in the electrode sheets are not consistent. The following explains why three sets of electrodes are used:
as shown in fig. 2, the electrode plate is usually applied to the affected part of the patient, which is a way of treating the patient with the capacitor electrode in short wave treatment; because the output signal of the short wave therapeutic apparatus is usually a high-frequency signal of 27.12MHz, the signal can not directly act on a human body, so a corresponding tuning loop is needed to convert the high-frequency signal into a signal suitable for the treatment of a human patient;
as shown in fig. 3 and 4, a tuning loop of a conventional short-wave therapeutic apparatus is formed by connecting an inductor and a capacitor in series, wherein a capacitance value C = C1+ C2, an inductance value L = L1+ L2, a capacitive reactance XC = 1/(2 pi fC), and an inductive reactance XL =2 pi fL, where L1 and L2 refer to inductance values of two induction coils, C1 refers to a capacitance value of an air capacitor, and C2 refers to a capacitance value generated by two electrode plates.
When inductive reactance XL in the tuning loop is equal to capacitive reactance XC, the resonance intensity is strongest, and the output power of the therapeutic apparatus is highest; when the capacitive reactance in the tuning loop is far unequal to the inductive reactance, the output power of the tuning loop is very low;
in a tuning loop, the inductance L and the frequency f of the short-wave therapeutic apparatus are constant, namely the inductive reactance is constant; however, the capacitance C of the short-wave therapeutic apparatus is inconsistent due to many factors, that is, capacitive reactance is not constant, for example, when the affected part of the human body or the clothes are inconsistent, the distance between the two electrode plates and the dielectric constant are also inconsistent, and further the capacitance C2 is inconsistent, so that the capacitance C1 is usually adjusted to ensure the therapeutic effect during the signal output process. It is known that the adjustable range of the capacitor C1 of the air capacitor is limited, and the air capacitor cannot be made into a large debugging range, and cannot meet the requirement that the capacitance reactance approaches the inductive reactance value by adjusting the capacitor C1 under all conditions, so that the capacitance reactance approaches the inductive reactance by changing the capacitance value C2 of the electrode plate, and the purpose of outputting high power is achieved, that is, when a patient is in a treatment process, the adjustment of the capacitor C1 cannot meet the requirement of outputting proper power, or the output power is low, the electrode plates with other capacitance values need to be replaced; therefore, the conventional short-wave therapeutic apparatus is usually provided with three sets of electrode plates with different metal areas to change the capacitance value C2.
The treatment equipment matched with three sets of electrode plates with different metal areas of the short wave treatment instrument usually has the following problems: that is, when the electrodes are used, the power output requirement cannot be met during tuning, and the electrodes need to be replaced, so that the treatment efficiency is influenced, and the three sets of electrodes also cause great waste in material cost.
