Description
Technical Field
The utility model relates to a treatment head on the magnetic field physiotherapy equipment, in particular to a multi-coil treatment head, which belongs to the technical field of medical equipment.
Background
The magnetic field physiotherapy instrument is a commonly used physiotherapy device in traditional Chinese medicine physiotherapy, for example, the laser magnetic field physiotherapy instrument combined with laser therapy at present adopts two treatment physical quantities of high-intensity magnetic field and low-intensity laser irradiation. The magnetic field with high magnetic induction intensity is used for regulating the magnetic field in the organism, generating induction micro-current, changing the permeability of cell membranes, increasing the activity of choline mediator, histaminase and kininase, expanding blood vessels and accelerating blood flow, thereby achieving the therapeutic effects of relieving pain, reducing swelling and the like. The low-intensity laser irradiation is combined with a magnetic field to interact with biological tissues to cause laser biological effect, and thermal effect, photochemical effect, pressure effect, electromagnetic effect and biological stimulation effect are generated. The curative effect and action thereof have been well proven in clinical practice. Present magnetic field physiotherapy equipment is provided with the coil in the shell internal fixation, is provided with the coolant liquid chamber on the shell, and the coolant liquid adopts oil or water, through the coolant liquid cooling, present treatment head has following problem in the concrete use: firstly, a single coil is adopted, the intensity of a magnetic field is in direct proportion to the coil and the current passing through the coil, and the number of turns of the single coil is certain, so that the adjustment of the intensity of the magnetic field needs to be realized by adjusting the current, which provides higher requirements for the design of a current generating circuit in the physiotherapy instrument, and particularly under the condition of low requirement on the magnetic field intensity, the accurate realization is difficult; secondly, the radius of the single coil is certain, if the area needing physical therapy is much smaller than that of the therapy head in physical therapy, the existing single coil therapy head cannot realize accurate therapy, and energy waste is caused.
Disclosure of Invention
An object of the utility model is to overcome the above-mentioned problem that present single coil treatment head exists, provide a multi-coil treatment head.
In order to realize the purpose of the utility model, the following technical proposal is adopted: the utility model provides a multi-coil treatment head, includes the shell, is provided with the coil in the shell, its characterized in that: the coils are mutually independent and are provided with independent lead wires.
Further, the method comprises the following steps of; the coil is arranged on the ceramic heat dissipation seat, and the ceramic heat dissipation seat is provided with a cooling water path.
Further, the method comprises the following steps of; the plurality of coils are arranged in a mutually embedded manner.
Further, the method comprises the following steps of; the three coils are respectively a small coil, a middle coil and a large coil, the small coil is positioned in the middle coil, the middle coil is positioned in the large coil, and the three coils are positioned on the same plane.
The utility model discloses an actively beneficial technological effect lies in: this multi-coil treatment head is last to have a plurality of coils, not only can adjust through the electric current when adjusting magnetic field intensity, also can change the coil number of turns through selecting to use different coil and coil combination to reach the purpose of adjustment magnetic field intensity, this kind of mode has reduced the requirement of the electric current generating circuit in the magnetic field physiotherapy equipment, make equipment make and accurate control more easily, this treatment head can also select little coil when the area of physiotherapy is less, can save energy consumption, reduce equipment and generate heat, it is good to adopt ceramic seat radiating effect.

Detailed Description
In order to explain the utility model more fully, the utility model provides an implementation example. These examples are merely illustrative of the present invention and do not limit the scope of the present invention.
The invention is explained in further detail with reference to the drawings, in which the reference symbols are: 1: a lower housing; 2: an upper housing; 3: a ceramic heat sink base; 4: a large coil; 5: a middle coil; 6: a small coil.
As shown in the attached drawing, figure 1 is an embodiment adopting the ceramic base to dissipate heat, and the multi-coil therapeutic head comprises a shell, wherein the shell comprises a lower shell body 1 and an upper shell body 2, a coil is arranged in the shell, the coil is arranged on a ceramic heat dissipation base 3, a cooling cavity is arranged on the ceramic heat dissipation base, circulating water can be connected to the cooling cavity for heat dissipation when in use, the cooling cavity can be arranged at the end, without the coil, of the ceramic base, and the cooling cavity can be cooled by the circulating water. In this embodiment, the number of the coils is three, and the three coils are respectively a small coil 6, a medium coil 5 and a large coil 4, the small coil 6 is located in the medium coil 5, the medium coil 5 is located in the large coil 4, and the three coils are located on the same plane.
Fig. 2 is a schematic view of a conventional cooling method using a cooling liquid chamber provided in a housing, and the present application divides an original independent large coil into three independent coils which are engaged with each other, as compared with a conventional therapy head.
The utility model discloses a three coil in treatment head, can set up the switch of independent control on the lead wire, then all connect on the output of magnetic field physiotherapy equipment, can be through the circular telegram of control different coil, and the size of electric current adjusts magnetic field intensity and magnetic field emergence area, the shape, when three coil is whole circular telegrams, magnetic field emergence area is the biggest, only when little coil circular telegram, magnetic field is a less circular of area, little coil does not circular telegram, when other coils circular telegrams, magnetic field is the annular, can be according to the treatment position selection coil or the coil combination of circular telegram of difference, reach nimble purpose of adjusting, can satisfy different demands in patient's treatment.
After the embodiments of the present invention have been described in detail, those skilled in the art can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above claims, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention all fall within the scope of the technical solution of the present invention, and the present invention is not limited to the embodiments of the examples given in the specification.
