Description

Detailed Description of the Invention "Industrial Application Field" The present invention relates to an electrode adsorption device for living organisms, and in particular, pressurized air is introduced into an adsorption type induction electrode to easily attach the electrode to the skin surface of a living body. This invention relates to a biological electrode adsorption device capable of adsorption.

"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. ! Samurai's bioelectricity of the heart uses an external electrocardiograph to detect weak currents induced on the skin of a living body to diagnose heart 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 adopts a suction method by bringing it into close contact with the skin surface of a living body.The conventional rubber suction electrode 1 has a suction hole 3 of a semicircular metal electrode cup 2 and a hollow A terminal 7 is connected to the opening 5 of the rubber dropper 4 through a metal hollow vibro, and is guided to the input side of an electrocardiograph (not shown) on the outer spherical surface of the electrode cup 2.
This is a structure in which the two are connected.

To use such a conventional rubber suction electrode 1, first press the rubber dropper 4 with your 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 and the pressing force of this hand is released, the pressure inside the electrode cup 2 is reduced by the elastic restoring force of the rubber dropper 1, and the rubber suction electrode 1 is attracted to the skin surface. I try to let them do it.

``Problems to be Solved by the Invention'' By the way, abnormalities in the heart are diagnosed by guiding the weak current generated in the heart by attaching the rubber adsorption electrode 1 to the skin surface to an electrocardiograph. Since the rubber suction electrode 1 has a considerable suction force, there is an inconvenience 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 severe discomfort. In addition, some people may experience pain and skin irritation, and some people with dense hair on their skin may experience problems such as poor adsorption.

``Means for Solving the Problems'' Therefore, the present invention has been made by focusing on such conventional problems. An electrode tube support arm 14, which is attached to the support column 1, projects horizontally from the rotation section 11, and is suspended from the rotation section II (!: an electrode tube support arm 14 that can be moved both horizontally and vertically). an electrode tube 17, an adsorption type induction electrode 18 attached to one end of the electrode tube 17 and adsorbed to the skin surface of the living body, and a pressure pump for quickly introducing pressurized air into the adsorption type induction electrode 18. It is an object of the present invention to solve the above-mentioned problems by providing an electrode suction device for living organisms having excellent suction properties and improved operability for attachment and detachment of electrodes. This is the purpose.

``Example'' Hereinafter, how the configuration of the present invention is actually embodied will be explained with reference to the drawings, together with its operation.

Further, a ventilation hole 28 is formed in the top surface portion 22 adjacent to the fitting groove 27, and the opening portion 24 and the insertion hole 26 are communicated with each other.

As shown in FIG. 3, the electrode plate support part 20 has a circular electrode plate support plate 29, and a nozzle pipe 30 is fixedly installed on the outer surface of this electrode plate support plate 29. In the nozzle pipe 30, there is an injection nozzle 3"1 as shown in FIG.
However, its tip is formed with a narrowed diameter. Further, the electrode plate 21 shown in FIG. 3 is detachably fixed to the back surface of the electrode support plate 29 with screws 32 as shown in FIG. The electrode support plate 29 can also be used as the electrode plate 4, but the electrode plate corrodes when it comes into close contact with the cream applied to the skin of a living body, and as a result it must be replaced. The 29-kichi electrode plate 21 is separable so that it can be replaced at any time.

As shown in FIG. 5, the electrode support part 20 to which the electrode plate 21 is fixed has its nozzle pipe 30 inserted into the insertion groove 26 of the suction cup 19, and at the same time, the electrode support plate 29 is inserted into the insertion groove 26 of the suction cup 19. By fitting into the fitting groove 27, the suction cup 19 is fitted. When the nozzle tube 30 is inserted into the insertion groove 26, one end of the nozzle tube 30 protrudes from the suction cup 9 and is fitted into a holder 33 attached to the base end of the rubber electrode tube 17. will be combined.

The pressurized air is also discharged to the outside of the suction cup 19. When the air inside the opening 24 is discharged, the opening 1] inside the opening 24 (negative pressure phenomenon suddenly occurs), and as a result, the suction cup 19
The skin surface connected to the contact piece 23 is sucked upward, the skin surface is attracted by the contact piece 23, and the suction type induction electrode 18 is brought into close contact with the skin surface. After the cardiac examination is completed in this way, if the operation of the pressurizing pump is stopped, the suction cup-type induction electrode 18 (!: The suction on the skin will be easily released) 4. "Effects of the present invention" According to the present invention, pressurized air is introduced into the suction type induction electrode to generate a negative king phenomenon between the skin surface of the living body and the suction type induction electrode, thereby attaching the suction type induction electrode to the skin surface. Since it is made to be adsorbed, there is no need to press the adsorption electrode against the skin surface to adsorb it, unlike conventional rubber adsorption electrodes, and as a result, you will not feel any pain, and even people with sensitive skin will be able to avoid inflammation. Nothing will happen.

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 device, the traces of the electrodes disappear after 1 to 2 hours, and the discomfort disappears.

Furthermore, when adsorbing induction electrodes are placed in close contact with the skin, it is only necessary to start the pressure pump, and when the electrodes are removed from the skin, the pressure pump can be stopped, which greatly improves the operability of attaching and detaching the electrodes. This has the advantage of reducing the fatigue of laboratory technicians.
