Description

Detailed Description of the Invention "Field of Industrial Application" The present invention relates to an adsorption type induction electrode for biological use, and particularly relates to an adsorption type induction electrode for biological use, and in particular, pressurized air is introduced into an adsorption type electrode to generate a negative pressure between the skin surface and the electrode. This invention relates to an adsorption-type induction electrode for biological use that has improved adsorption properties by increasing adsorption properties.

"Conventional technology" As is well known, the bioelectricity generated in the living body is the heart.

It is induced by the activities of the brain, muscles, etc. In particular, cardiac bioelectricity is detected by detecting weak currents induced on the skin of a living body using an external electrocardiograph to diagnose cardiac abnormalities. This electrocardiograph requires electrodes to be brought into close contact with the surface of the skin in order to electrically connect the input section to the living body.

A conventional electrode that is brought into close contact with the skin surface will be explained with reference to FIG. The electrode shown in Fig. 6 employs a suction method as a means of bringing it into close contact with the skin surface of a living body.The conventional rubber suction electrode 1 consists of a suction hole 3 of a semicircular metal electrode cup 2 and a hollow rubber suction electrode 1. It has a structure in which the opening 5 of the dropper 4 is communicated with a metal hollow vibro, and a terminal 7 that is led to the input side of an electrocardiograph (not shown) is connected to the outer spherical surface of the electrode cup 2.

To use such a conventional rubber suction electrode 1, first press the rubber dropper 4 by hand and then apply pressure to the skin surface 8 of the living body.
When the electrode cup 2 is brought into contact with the top of the skin, and then the pressing force of this hand is released, the elastic restoring force of the rubber dropper 4 reduces the pressure inside the electrode cup 2, thereby adsorbing the rubber adsorption electrode 1 to the skin surface. I try to let them do it.

"Problems to be Solved by the Invention" □ By the way, cardiac abnormalities are diagnosed by attaching the rubber adsorption electrode 1 to the skin surface and guiding the weak current generated in the heart to an electrocardiograph. Since this rubber suction electrode 1 has a considerable suction force, there is an inconvenience in that the roots of the semicircular electrode cup 2 remain on the skin surface for several days after using the rubber suction electrode 1, causing extreme discomfort. Ta. However, some people may experience pain and inflammation on their skin, or people with dense hair on their skin may have problems with poor adsorption.

Further, an adjustment nozzle 33 is screwed into the nozzle pipe 31 opposite to this injection nozzle 32, and a gap S is provided between this adjustment nozzle 33 and the injection nozzle 32 (!:). By changing the alignment position, the gap S is widened or narrowed.By widening or narrowing the gap S, the amount of air sucked into the opening 25 is increased or decreased, thereby increasing or decreasing the suction force. Furthermore, a ventilation hole 34 is bored in the circumferential surface of the nozzle pipe 31 as shown in FIGS.
When inserted into the suction cup 22 , it communicates with the communication hole 29 formed in the suction cup 22 and is located below the gap S formed between the injection nozzle 32 and the adjustment nozzle 33 .

Ru. Electrode plate? =1 Is it possible to use the electrode plate support plate as an electrode plate? The electrode plate is applied to the skin surface or comes into contact with l-A, and the electrode plate itself corrodes and must be replaced. Therefore, the electrode plate support plate 30 and the electrode plate 34 are made separable so that they can be replaced at any time.

A conductive sponge 37 shown in FIG. 2 is attached to the lower surface of the electrode plate 34 as shown in FIGS. 3 and 4.

Next, to explain how to use the biological suction type electrode 18 configured as above, first, as shown in FIG. The electrode suction device 9 is transported near the bed O;. Next, the foot switches to 20 of the pressurizing pump 19 are operated to supply pressurized air to the column 10. After this pressurized air is introduced into the support column 0, the electrode tube support arm 14 is rotated horizontally and moved up and down, and the suction cup 19 of the suction type induction electrode 18 attached to the tip of the electrode tube 17 is moved. The contact piece 23 is brought into contact with the patient's skin surface.

When this suction type induction electrode 18 comes into contact with the patient's skin surface,
The pressurized air sent into the support column 10 is transferred to the support arm 14;
The liquid passes through the electrode tube 17 and enters the nozzle tube 31 of the adsorption type induction electrode 18, and is vigorously injected from the injection nozzle 32 whose tip is constricted. This pressurized air is sent to the injection nozzle 32
As shown in FIG. 4, when the air is injected from the opening 25 formed between the adhesive piece 24 and the skin surface, the air flows through the communication hole 292, the ventilation hole 34. The pressurized air is discharged to the outside of the suction cup 22 from the discharge port 41 through the gap S1 adjustment nozzle 33 formed between the injection nozzle 32 and the adjustment nozzle 33. When the air in this opening 25 is discharged, the skin surface that is in contact with the contact piece 24 of the suction cup 22 is sucked upward, and the skin surface is attracted to the contact piece 24 and becomes an adsorption type induction electrode. 18 comes into close contact with the skin surface.

After the cardiac examination is completed in this way, the suction between the suction type induction electrode 18 and the skin surface can be easily released by stopping the drive of the pressurizing pump.

"Effects of the Present Invention" According to the present invention, pressurized air is fed into the suction type induction electrode to generate a negative pressure phenomenon between the skin surface of the living body and the suction type induction electrode. Adsorb 5″t6,

It is no longer necessary to forcefully press the suction electrode against the skin surface for suction, and as a result, there is no pain, and even people with sensitive skin will not experience irritation.

In addition, with conventional rubber suction electrodes, the traces of the suction electrodes adsorbed to the skin surface do not disappear for several days, but with this suction type electrode,
As time passes, the traces of the electrodes will completely disappear and the discomfort will disappear.

Furthermore, since a conductive sponge impregnated with a conductive liquid substance is attached to the electrode plate so that it comes into contact with the skin surface, the electrode can be brought into close contact with even people with hairy skin, further improving the suction power.

Furthermore, since the adjustment nozzle is screwed into the nozzle pipe facing the injection nozzle, the gap between the injection nozzle and the adjustment nozzle can be adjusted as desired, and as a result, the amount of air sucked into the opening can be adjusted. , it is convenient to increase or decrease the suction power.

In addition, since the electrode plate with the electrode plate support plate can be separated and the electrode plate can be detachably attached to the electrode plate support plate, there are advantages such as the electrode plate can be easily replaced.
