Description

[Detailed description of the invention] 〔Technical field〕 The present invention relates to a blood circulation promoting device.

[Background technology]

To recover from stiff shoulders and muscle pain, it is effective to apply electromagnetic fields to specific parts of the body to promote blood circulation.

To this end, it is simple and effective to attach the blood circulation promoting device directly to the skin where stiff shoulders are occurring or to wear it on the person's body. Recently, as a device for pasting in this way, one unit is constructed by incorporating an electromagnetic field generating circuit, a battery to drive it, and an antenna for forming the electromagnetic field into a case that is attached to the affected area. There is.

Since this device is unitized, it is very convenient to handle.

FIG. 8(a) shows an example of a unitized device. This device is equipped with a device case C and an adhesive 1 applied to its lower surface, and as shown in the same figure,
It can be attached to parts of the body using adhesive.

However, since the conventional device case C has an angular shape in which the top surface 2 and the peripheral side surface 3 form a right angle, clothing may rub against the corner 4 of the device case C, causing the device case C to move in the direction along the mounting surface. It was something that made it possible to move. As a result, the rubbing force comes to pull the skin through the adhesive l, which causes a mechanical irritation that causes a rash on the skin.

[Purpose of the invention]

In view of the above circumstances, an object of the present invention is to provide a blood circulation promoting device that prevents skin irritation caused by mechanical stimulation.

[Disclosure of the invention]

In order to achieve the above object, the blood circulation promoting device according to the present invention is characterized in that the outer peripheral portion of the device case is formed by a surface that gently descends from the upper surface to the peripheral side.

Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments thereof.

Fig. 1 shows an embodiment of the blood circulation promoting device according to the present invention seen from the front, Fig. 2 shows a partially exploded cross section, and Fig. 3 shows this blood circulation promoting device from the top. When I saw it, it hailed me.

As seen in these figures, this blood circulation promoting device includes a device case C made of plastic material. Case C consists of a case body 5 and a battery cover 6. The case body 5 is formed by stacking a lower case 7 and an upper case 8 vertically and joining them into a sealed cane using an ultrasonic welder.

This is to improve waterproofness. The lower case 7 has a flat disk shape, and is provided with a battery inlet/outlet 9 at its center. The battery cover 6 has a disk shape, and when it is rotated in one direction through a rotation operation port 10 formed in the center, a locking piece 11 protruding from the inner outer circumference of the cover 6 is rotated at the bottom. It engages with the inner circumferential edge of the case 7 near the battery entrance/exit 9, and is released by rotating in the other direction. A gasket 12 is interposed between the battery cover 6 and the lower case 7 to improve sealing performance.

The upper case 8 is integrated with a flat cover having an open bottom and a wall on the top, and a battery 13 is inserted therein so as to be inserted and removed through the battery entrance 9. . A cylindrical partition wall 14 protrudes inside the upper case 8 so as to cover the battery 13 from the outer periphery. A donut-shaped circuit board 15 is installed on the outer periphery side of the partition wall 14, and on the upper surface side of this circuit board 15, circuit elements 16 constituting an electromagnetic field generation circuit are arranged. On the lower surface side of the circuit board 15, as shown in FIG. 4, a loop-shaped antenna 17 is provided. These electric circuits will be described later.

By the way, the upper surface center portion 8a of the upper case 8 is formed as a horizontal and slightly high wall portion and has a power switch SW in the center, and the outer peripheral portion 8b of the upper case 8 is formed as a horizontal and slightly high wall portion, and the outer peripheral portion 8b of the upper case 8 is It is formed into a curved shape that descends lower as it reaches. A mounting means 20 is attached to the lower surface 19 of the device case C. This attachment means 2o is adapted to be attached to the affected area via a breathable cushion sheet 22 with adhesive sheets 21 and 21 laminated on both sides. That is, one adhesive sheet 21 is attached to the back surfaces of the lower case 7 and battery cover 6, and the other adhesive sheet 21 is attached to the affected area. The cushion sheet 22 may be made of foamed material such as polyurethane or polyester.

As mentioned above, since the portion from the top surface to the peripheral side of the device case C is rounded like a curved surface, when the device is worn on the body, clothes will rub and the skin will be pulled through the attachment means 20. There is no such fear. This results in
Since the skin is not subject to mechanical stimulation, there is no chance of getting a rash.

As shown in the above embodiment, when the mounting means 20 includes the cushion sheet 22, the cushion sheet 22 absorbs the force that generates mechanical stimulation in the middle, and prevents skin irritation even more effectively. It is something that can be done.

FIG. 5 shows another embodiment. This example is
Outer peripheral portion 8 with a smaller radius of curvature than the embodiment shown in FIG.
b. Note that an adhesive 23 is applied to the lower surface 19. If the adhesive 23 is selected to be one that can be easily removed with a solvent or the like, it is very convenient because when the adhesive strength of the adhesive decreases, the adhesive can be easily removed and reapplied.

FIG. 6 also shows another embodiment. In this example, the outer peripheral portion 8b is formed by an inclined surface.

The circuit element 16 is mainly a component for an electromagnetic field generating circuit, and the circuit element 16 has a detailed circuit configuration as shown in the figure. In other words, as shown in FIG. 7, the oscillation circuit consists of a Colpitts-type LC oscillation circuit 27 consisting of resistors RI, Rt, capacitors C+, Cz, ) transistor Q, and inductance L1, resistors R3 to R6, and a capacitor. Cal.

It consists of a multivibrator 28 consisting of C4, transistors Qz, and C3, and a display circuit 29 consisting of a resistor R1, a transistor Q4, and a light emitting diode LED. When the battery power switch SW is turned on, the multivibrator 28 oscillates, and its The base current of the transistor Q1 of the oscillation circuit 27 is supplied by the oscillation output, and the oscillation circuit 27 operates in oscillation, generating an electromagnetic field modulated by the output of the multivibrator 28. This electromagnetic field is radiated via an antenna 17 coupled to an inductance L. Here, the modulation by the multivibrator 28 is intended to maintain the blood circulation promotion device to the living body and to save power. The output of the multi-by-break 28 is applied to the base of the transistor Q4 of the display circuit 29, and the transistor Q4 is intermittently switched.
4 displays the usage status by blinking the light emitting diodes LEDs connected in series.

〔Effect of the invention〕

As seen above, the blood circulation promoting device according to the present invention is characterized in that the outer peripheral portion of the device case is formed by a surface that gently descends from the top surface to the peripheral side, so that the blood circulation promoting device according to the present invention is free from mechanical stimulation. This prevents rashes on the skin.
