Description
The present invention relates to medical apparatus and instruments, particularly the high-frequency induction heat electric fire needle medical apparatus and instruments.
Fire acupuncture disease is a kind of fruitful traditional medical method of the traditional Chinese medical science, has indication very widely, and the mankind's health care has been played positive facilitation.
From traditional charcoal fire heating, the alcohol burner heating develops into electrical induction, and fiery pin heating means have had obvious improvement.Common induction heating is that fiery pin is sent in the load coil, is heated to take out after the red heat to carry out acupuncture patient acupuncture point immediately.This heating means health, safety, syringe needle directly do not contact power supply and thermal source, and is more far better than the alcohol burner heating.But the syringe needle of common induction heating and heater coil are isolating two systems.Therefore cause operation convenient inadequately, shortcomings such as wayward fiery pin temperature.
The purpose of this invention is to provide a kind of electrical induction fire pin medical apparatus and instruments, this medical apparatus and instruments is easy to operate, can arbitrarily control the temperature of fiery pin, has overtemperature protection system, and energy consumption is low, the scalable needle length.Can arbitrarily change the syringe needle of different shape as required.
According to the present invention, the high-frequency induction heat electric fire needle medical apparatus and instruments is that high-frequency induction heating power and needle body, connection cord are formed, and this cable couples together high-frequency induction heating power and needle body.
According to the present invention, high-frequency induction heating power is made up of mains transformer, overheating protection circuit and special-purpose high frequency generator.By mains transformer the 220V electric network source is become the used 1～37V work of this machine piezoelectric voltage, regulate this voltage with an adjustable potentiometer.
According to the present invention, overheating protection circuit is made up of an adjustable resistance, an electric capacity, an overheat protective relay, an audion and another resistance.
According to the present invention, special-purpose high frequency generator is made up of two resistance, two electric capacity, an oscillating tube and one group of oscillator coil.By suitable apolegamy component parameters, reach and cut down the consumption of energy, improve the purpose of the thermal efficiency.
According to the present invention, needle body is by the inner needle tube of a rear end cap, a trough of belt mouth, outer needle tubing, be contained in spring in this inner needle tube, be contained in shifting block and screw in the notch, the cylindrical slider that can in inner needle tube, slide that links to each other with this screw, be fixed on fiery pin in this slide block, be contained in outside in the needle tubing and surround before induction coil, the outer needle tubing drive end bearing bracket of fiery pin portion and the parts such as on and off switch that are contained in the inner needle tube rear end form.Shifting block movable cylindrical slider that drives in notch slides in inner needle tube.When sliding backward, the rear end of slide block compression spring, fiery pin is oppressed on and off switch and is connected circuit, makes induction coil obtain high-frequency electrical, and this moment, fiery needle point just in time was among the induction coil, and behind the several seconds pin, needle point just can be heated to 700～800 ℃.Unclamp shifting block, needle point penetrates needle tubing and thrusts patient acupuncture point on one's body under the effect of spring, and at this moment switch disconnects.If shifting block is not unclamped in the generation maloperation, switch continues closed, and at this moment overheating protection circuit works, and behind certain hour, the relay normally closed contact in this circuit is opened, and the high-frequency oscillating circuits outage stops heating automatically.
Adopt electrical induction electric fire needle of the present invention, have advantages such as easy to use, that power consumption is low, heating is fast, and the patient does not directly contact electricity can arbitrarily control fiery pin heating-up temperature, and structural safety is reliable, can be widely used in the fire needle therapeutic of various conditions.
