Description

Magnetic stimulation treatment head

Technical Field

The utility model relates to magnetic stimulation equipment, in particular to a treatment head connected with the magnetic stimulation equipment, and belongs to the technical field of magnetic stimulation treatment heads.

Background

For example, the transcranial magnetic stimulation equipment utilizes the electromagnetic induction principle, the energy storage capacitor discharges rapidly to the stimulation coil, a large current is generated in the stimulation coil, a strong magnetic field is generated by the stimulation coil for treatment, the stimulation coil generates a large amount of heat because the stimulation coil has resistance, so that the temperature of the stimulation beat which is in contact with the human body is quickly over 41 ℃ and cannot be over 41 ℃ according to national standard requirements, the magnetic stimulation treatment head (stimulation beat) needs to be cooled, the current magnetic stimulation treatment head is arranged in the shell, the external air cooling is adopted in the cooling mode, namely, a cooling fan is arranged on the treatment head, the mode leads to the excessively large volume and the excessively heavy weight of the treatment head, and manual operation is difficult in clinic; the fan is noisy in operation, so that people feel dysphoric when the head is treated, the treatment is unfavorable, and the cooling effect of the treatment head is poor when the ambient temperature is high; secondly, the internal cooling coil is made of a hollow copper tube, a cooling medium circulates in the copper tube, the cooling medium circulates between the coil and a unit for cooling the cooling medium, the mode is better than an air cooling effect, but the mode has the defects that when the ambient temperature is higher (more than 30 ℃), the national standard required temperature (not exceeding 41 ℃) of the magnetic stimulation beat and the ambient temperature are very small, the heat exchange efficiency of the cooling medium is very low, the cooling effect is very poor, the cooling purpose can not be achieved, a high-temperature alarm can be started when half period equipment is treated, the treatment progress is seriously influenced, and in order to solve the problem, the Chinese patent number 202121708161 also provides a double-water-tank cooling device for the magnetic treatment head, which clearly increases the complexity of a cooling system and control of the cooling system, so how to design and manufacture the magnetic stimulation beat treatment head with simpler cooling is one aspect of the magnetic stimulation equipment.

Detailed Description

In order to more fully explain the practice of the utility model, examples of the practice of the utility model are provided. These examples are merely illustrative of the present utility model and do not limit the scope of the utility model.

The utility model will be explained in further detail with reference to the accompanying drawings, in which: 1: a coil; 2: a housing; 3: a cooling liquid inlet; 4: a cooling liquid outlet; 5: a heat insulation layer; 6: a housing; 7: a cavity; 8: a temperature sensor; 9: a liquid inlet; 10: and a liquid outlet.

The design of the magnetic stimulation treatment head is different from that of a traditional treatment head, the traditional air-cooled treatment head is designed to enable heat generated by a coil to be emitted from the surface of the treatment head, a water-cooled treatment instrument is used for taking away most of the heat through cooling liquid and emitting a small part of the heat through the treatment head, so that the temperature of the treatment head is guaranteed, the traditional treatment head is abandoned in design, the heat generated by the coil is 'looped' in a shell, most of the heat generated by the coil is 'looped' in the shell due to the existence of a heat insulation layer, the temperature of the copper is very small, the resistance of a copper tube is not greatly increased due to the temperature rise, the copper tube and an insulating layer thereof can withstand the temperature of at least 150 ℃, namely, the temperature in the shell is only controlled below 150 ℃, the environment temperature is mostly below 40 ℃, the temperature difference of about 100 ℃ is generated between the stimulation coil and the environment, the heat exchange efficiency between the stimulation coil and the cooling liquid and the environment is improved, and the stimulation coil is protected from being damaged. The shell is contacted with the human body, so that the temperature of the shell is ensured not to exceed 41 ℃, and the inner cavity only transmits little heat to the shell due to the existence of the heat insulation layer, so that the cooling effect can be realized by using little refrigeration power.

As shown in the drawing, the magnetic stimulation treatment head comprises a coil 1 made of a hollow copper tube, the coil is arranged in a shell 2, a cooling liquid inlet 3 and a cooling liquid outlet 4 are arranged on the shell, the cooling liquid inlet and the cooling liquid outlet are respectively connected with two ends of the hollow copper tube, and are the same as the traditional magnetic stimulation treatment head, and the cooling liquid inlet and the cooling liquid outlet are connected with a circulating cooling system, so that the magnetic stimulation treatment head adopting hollow copper as the coil and a cooling structure configured by the magnetic stimulation treatment head are mostly adopted at present.

The heat-insulating layer 5 is arranged outside the shell 2, the heat-insulating layer can be epoxy resin pouring sealant with low heat conductivity coefficient, the shell 6 is arranged outside the heat-insulating layer, the cavity 7 is arranged in the shell, the temperature sensor 8 is arranged in the cavity and connected to the controller, the liquid inlet 9 and the liquid outlet 10 are arranged on the cavity, and the liquid inlet 9 and the liquid outlet 10 are connected to the liquid circulation heat dissipation system. Hydronic heat dissipation systems are currently in the prior art. Such as the cooling devices disclosed in chinese patent nos. 2021218708208, 201821405443.9.

Having described embodiments of the present utility model in detail, it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the scope and spirit of the utility model as defined in the appended claims, and any simple, equivalent changes and modifications to the above examples are intended to be within the scope of the present utility model and the utility model is not limited to the embodiments as set forth in the specification.
