Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of graphite ene coatings electric heat needle for acupuncture of efficient heat production.
Background technique
Acupuncture is the important component of Chinese medicine succession, is to stimulate the acupuncture point on collaterals of human to reach by being needled into human body
It is a kind for the treatment of means from outside to inside to the purpose for the treatment of.Warm needle acupuncture is the important component of acupuncture and moxibustion treatment, ancient times
It is main to be realized by burning moxa heat production.With the development of electronics science, warm needle therapeutic equipment is also constantly updated, and a system occurs
The electrical-heated needle for acupuncture (hereinafter referred to as electric heat needle for acupuncture) of column, electric heat needle for acupuncture is broadly divided into radio frequency type and resistor-type two by heating feature at present
Type.Radio frequency type electric heat needle for acupuncture is then to issue rf wave in needle point to hit ion and the oscillation of polarity macromolecular in its surrounding tissue
Frictional heating realizes the heating of needle body perienchyma.If patent CN104706419A devises a kind of acupuncture radio frequency acusector,
Needle point constructs radio frequency output electrode and issues radio-frequency current induction perienchyma's heat production；It is more that patent CN105726305A devises one kind
The coaxial configuration radio frequency electric heat needle for acupuncture of layer metal and insulating layer, interior metal axle and outer metal layer are exposed at needle point, when needle point pierces
After entering the human body, two layers with the organizational composition treatment circuit near needle point to heat production.Radio frequency type electric heat needle for acupuncture heat production is high-efficient, produces
Thermal potential sets the accuracy for being accurately conducive to treatment, but its structure is complex, and heat production temperature is difficult effectively to control, and has high frequency
Electric current flows through perienchyma, and safety still has certain doubt, and there is also certain limitations in actual use.
Resistor-type electric heat needle for acupuncture is mainly when electric current flows through big resistance by Joule's law heat production, such as patent CN106265060A
The heating of needle body itself is realized using the resistance building circuit of hollow needle body itself；Patent CN2390600 is in hollow needle interior wall
It winds resistance wire and realizes the heat production of needle point position；Patent CN101947187A winds resistance wire on needle handle, then is aided with insulating coating,
It is imported by the heat that needle body generates resistance wire internal.Compared to radio frequency type electric heat needle for acupuncture, resistor-type electric heat needle for acupuncture has safety can
It leans on, the simple advantage of structure, heat production temperature is relatively easy to control, and resistor-type electric heat needle for acupuncture is to conduct heat to life again after needle body heat production
Object tissue, the characteristics of more meeting warm needle therapeutic, can preferably substitute traditional warm needle therapeutic needle set, but its heat production efficiency is lower, especially
It is that Thermogenesis is lower at low voltage, and high voltage can then cause certain harm to human body, not meet the requirement of warm needle.
Graphene is the two dimensional crystal material that a kind of single carbon atom is constituted, and has excellent electric property (electronics at room temperature
Mobility is up to 2 × 105cm2/ Vs) and heating conduction (5000W/mK).Its conductive and heat-conductive ability is more than most metals material,
Graphene has corrosion-resistant, good mechanical property and low density advantage simultaneously, it is made to have substituted metal in thermo electric material field
Potentiality, used in a variety of Electric radiant Heating Film patents.As patent CN104219797A devises a kind of graphene superconductive far infrared
Electric radiant Heating Film, graphene conductive slurry is fever core layer, then is aided with the Electric radiant Heating Film that the insulating protective layer of upper and lower two sides is composed,
The graphene Electric radiant Heating Film has suitable resistivity, shows the ultrafast rate of heat addition, and high heating conduction is dissipated with quick
Thermal energy power can conduct heat to rapidly other materials almost without thermal inertia, be precisely controlled to realize to temperature, and
Voltage needed for heat production is lower, can use within the scope of human safety voltage.In view of this, the material can be used as a kind of excellent production
Hot material is applied to the design of electric heat needle for acupuncture, and this aspect there is no report at present.
