Abstract

PURPOSE:To achieve a higher treating effect and a higher workability in assembling and disassembling by connecting a conducting sheet and an insulating sheet to a body case through a cylinder part while an electrode body is inserted with an insertion of a cylinder body into a mounting hole. CONSTITUTION:A cylinder body 12 is formed protruding upward from an insulating sheet 11 made of a soft rubber material and a soft conducting sheet 14 is applied entirely over an undersurface of an insulating sheet 11 and an internal surface of the cylinder body 12. The insulating sheet 11 has the cylinder body 12 inserted into a mounting hole 10 as being somewhat pressed and upon the completion of the insertion, a flange 13 is retained at an upper rim part of the mounting hole 10 to lock and held on an undersurface of a body case 2. Under such a condition, an electrode rod 15 is inserted into the cylinder body 12 as being somewhat pressed. With such an arrangement, as the conducting sheet and the insulating sheet are connected together through the body case and the cylinder body part, they deflects so well to fit even a curved part of a human body thereby achieving a higher treating effect. The mounting is completed simply by inserting the cylinder body into the mounting hole 10, and further, the electrode body. This achieves a higher workability in assembling and diassembling.

A contact part that comes into contact with the upper end of the cylindrical body when the scraping body is inserted a predetermined amount, and a circuit for generating an electrical stimulation signal are mounted, and the front part is electrically connected to the electrode body within the main body case. The device is equipped with a connected board.

(E) Function: Since the conductive sheet and the insulating sheet are simply connected to the main body case through the cylindrical portion, it can be easily bent and adapted to the curved surface of the human body.

Moreover, attachment of the electrode sheet is completed by simply inserting the cylinder into the mounting hole I2 and further inserting the electrode body.

(f) Example Embodiments of the present invention will be described based on the drawings.

Reference numeral 1 denotes a pair of conductors that operate by receiving radio waves from a transmitter (not shown), and their shapes are the same except for whether they have a built-in battery power supply or a receiver circuit.

The structure of this conductor 1 will be explained below.

Reference numeral 2 denotes a main body case made of ABS resin, which is formed into a hollow shape by aligning the open ends of an upper case 3 with an open bottom and a lower case 4 with an open top. The main body case 2 is composed of a substantially square accommodating portion 5 and a cylindrical lead-out portion 6 protruding from one corner of the accommodating portion 5. Reference numeral 7 denotes a board disposed within the housing section 5, on which a low frequency oscillation circuit for generating electrical stimulation pulses, a battery power source, a receiving circuit, etc. are mounted. Reference numeral 8 denotes a lead wire that electrically connects the substrates 7 of the pair of conductors 1, and the end portion thereof is housed in the lead-out portion 6. Reference numeral 9 represents a contact portion provided at a predetermined position on the lower surface of this board, and reference numeral 10 represents a mounting hole provided on the bottom surface of the lower case 4.

Reference numeral 11 denotes an insulating sheet made of a soft rubber material, and 12 a cylinder projecting upward from the insulating sheet 11, the outer diameter of which is set to be the same as or slightly larger than the inner diameter of the mounting hole 10. 13 is a flange formed at the upper end of the cylinder 12; 14 is the lower surface of the insulating sheet 11 and the cylinder 12;
It is a soft conductive sheet that is adhered to the entire inner surface of the housing, and is made of silicone rubber.

The cylindrical body 12 of the insulating sheet IJ is almost press-fitted into the mounting hole 10 from below, and when the insertion is completed, the flange 13 is locked to the upper edge of the mounting hole 10. It prevents it from coming off and is held on the bottom surface of the main body case 2.

15 is an electrode rod that is almost press-fitted into the cylindrical body 12 in this state, 16 is a contact portion provided on this electrode body 15, and the lower end of this electrode rod 15 is from the bottom surface of the conductive sheet 14. It is provided at a position where it comes into contact with the upper end of the cylinder 12 before protruding. 17 is a spring interposed between the electrode body 15 and the contact portion 9 of the substrate 7 to electrically connect them; 18 is a conductive spring for attaching the main body case 2 to the affected area; It's an adhesive pad.

Note that the mounting hole 10, the cylinder body 12, and the electrode body 15 are
However, only one is electrically connected to the substrate 7.

The insulating sheet 11 can be attached to the main body case 2 by simply inserting the cylinder 12 into the mounting hole 10 and further inserting the electrode rod 15 into the cylinder 12.

Further, the spring 17 also serves as an electric wire and absorbs the vibration of the board 7 so that the influence of the vibration is not transmitted to the board 7.

Further, the lower end of the electrode rod 15 is connected to the conductive sheet 1.1.
Since the electrode body 15 is exposed to the extent that it does not protrude from the bottom surface, it does not get in the way even when the adhesive band 18 is attached, and the electrode body 15 can be removed without disassembling the main body case 2 during product inspection before shipping. The lower end of can be used as a terminal for measuring characteristics. In other words, if the conductive sheet 14 is used as a measurement terminal, accurate measurement cannot be performed due to variations in the resistance value of silicone rubber, but by using the electrode rod 15 as a terminal in this way, there is no such concern.

(g) Effects of the invention In the structure of the conductor of the low frequency treatment device according to the present invention,
Since the conductive sheet and the insulating sheet are connected to the main body case only through the cylindrical portion, it can be bent well and adapted to the curved surface of the human body.

Therefore, a good therapeutic effect can be exerted.

In addition, the installation of the electrode sheet is completed by simply inserting the cylinder into the installation hole and then inserting the electrode body, so the workability during assembly and disassembly is extremely good.
