Detailed Description
In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways than those specifically described herein, and thus the scope of the present invention is not limited by the specific embodiments disclosed below.
When the cervical vertebra massager in the prior art is used, the electrode plate is in contact with the skin of a human body due to elasticity, so that the electrode plate cannot be ensured to be in complete close contact with the skin, and current cannot uniformly flow to the human body through a contact surface with the skin. If the current is concentrated in a local small area of skin or even a point, a tingling sensation may be produced on the skin surface, and in severe cases, skin burns may occur.
As shown in fig. 1-3, in the specific embodiment 1, the utility model provides a cervical vertebra therapeutic apparatus, which comprises a therapeutic host, a left support arm 9 and a right support arm 8 movably connected to two sides of the therapeutic host for supporting, wherein the therapeutic host comprises a front fixed casing 7, a rear fixed casing 1, and a fixed frame 2 detachably connected to the front fixed casing 7, and the fixed frame 2 is provided with a therapeutic electrode for outputting an electrical pulse stimulation signal to a human body;
the treatment electrode comprises a plurality of metal electrode assemblies 6, a plurality of pressure-sensitive conducting strips 5 and a plurality of movably supported metal elastic pieces; one end face of any pressure-sensitive conducting strip 5 is embedded into the metal electrode assembly 6 at the corresponding mounting position, and the other end face of the pressure-sensitive conducting strip is abutted against the metal elastic piece at the corresponding mounting position. The thickness of the pressure-sensitive conducting sheet 5 is 5 mm-10 mm, the pressure-sensitive conducting sheet 5 is a carbon black filled pressure-sensitive conducting silicon rubber conducting sheet, the main material components are GD-401 type silicon rubber, acetylene black, a vulcanizing agent and a catalyst, and the content of the carbon black is 6% -8%.
The treatment electrode composed of the pressure-sensitive conductive silicon rubber can automatically induce the contact pressure to realize the automatic load changing characteristic, thereby solving the problem that the user feels stabbing pain and possible skin burns caused by incomplete contact of the electrode slice with the skin when in use.
The pressure-sensitive conductive silicone rubber has the advantages of flexibility, ductility and the like of polymer materials, and simultaneously has excellent conductive capability and pressure sensitivity. The resistance value of the pressure-sensitive conductive silicone rubber changes along with the change of pressure and is in a certain functional relationship, and the characteristic is called piezoresistive characteristic.
The piezoresistive characteristic curve of the pressure-sensitive conductive silicon rubber is in an L-shaped steep descending type, and the resistance value of the pressure-sensitive conductive silicon rubber is reduced along with the increase of the pressure. When the surface pressure borne by the pressure-sensitive conductive silicone rubber is smaller than a conduction threshold value, the material is in a high-resistance state, when the pressure exceeds the conduction threshold value, the conductivity is rapidly increased, the resistance value is close to zero resistance, and the resistance change tends to be flat along with the continuous increase of the pressure.
When a user uses the cervical vertebra therapeutic apparatus for treatment, when the treatment electrode is in contact with or separated from the skin, because the contact area of the electrode and the skin of a human body is small and the stress is small, the deformation of the spring 3 in the treatment electrode is small, the pressure-sensitive conductive silicon rubber is in a natural extension state, and the conductive resistance value of the pressure-sensitive conductive silicon rubber is larger than 10 kilo-ohms. If the current loop formed by connecting the human skin is equivalent to a circuit load, the current passing through the load is extremely small (microampere level, almost negligible), so that the electric pulse output is not triggered between the treatment electrodes to stimulate the human skin. When the treatment electrode is tightly attached to the neck skin of a human body, the spring 3 in the treatment electrode extrudes the pressure-sensitive conductive silicon rubber to deform the pressure-sensitive conductive silicon rubber due to stress deformation and generates a piezoresistive effect, the distance between conductive particles in the material is reduced, so that more conductive channels are formed in a unit volume to rapidly reduce the resistance of the material, and the current passing through the load is larger (30-50 milliamperes) to achieve the treatment effect.
The metal elastic part comprises a spring 3 and a metal lining plate 4; the spring 3 is connected with one side end face of the metal lining plate 4 in a welding mode to form electrical connection. The roughness of the outer surface of the metal lining plate 4 is Ra0.2.
The outer side of the metal electrode assembly 6 is an arc surface, and the central part of the inner side is embedded with a limit bracket.
The front fixed shell 7 is provided with a mounting hole site matched with the outer arc surface of the metal electrode assembly 6.
The periphery of the front fixed shell 7 is provided with connecting hole sites, the periphery of the rear fixed shell 1 is provided with connecting pins matched with the connecting hole sites of the front fixed shell 7, and the front fixed shell 7 is detachably connected with the rear fixed shell 1 through threads;
7 circles of preceding fixed casing are equipped with the connection boss, and 1 circles of back fixed casing are equipped with and are connected the recess of boss adaptation, connect the boss and cooperate with sealed treatment host computer with the recess, prevent inside electric leakage and effective waterproof dustproof guarantee inner structure life.
In other more specific embodiments, the left arm 9 and the right arm 8 are both arc-shaped arm structures with the inner sides adapted to the curve of the neck of the human body; an on-off button is arranged on the outer side of at least one of the left support arm 9 and the right support arm 8 and is used for controlling the opening and closing of the cervical vertebra therapeutic apparatus.
