DE1489693C - Protective device used to relieve pain in a wound or on the human epidermis caused by static electricity - Google Patents

Description

The invention relates to a protective device for alleviating the effects of static electricity Pain in a wound or a tender area of the human epidermis from a cap-shaped, tape-shaped or mat-shaped covering which is arranged on or over the epidermis.

It is known that animal bodies can absorb an electrostatic charge, which is caused by The voltage generated by this charge can vary widely and depend on numerous factors. These factors include the moisture content of the air, the movement of the body relative to others Bodies or objects, the state of health or vitality of the person concerned, etc. That Presence of such a charge can often generate weak blows or a visible one electrical discharge if the person concerned or a metal body touched. The electrical potential that builds up due to such a charge can vary between a few Volts and several thousand volts of voltage. It has been found that individuals with a dry Skin can build up a higher tension than people with normal or moist skin and that the tension on the skin surface changes in the opposite direction with the relative humidity. Also lies the electrical resistance of the skin surface and the electrical resistance that builds up accordingly Tension on the skin in people with reduced perspiration or in the absence of it of sweat to a higher value.

Although the physiological effect of static electricity on the body or the atmosphere a wound or a sensitive area of the epidermis is not yet known exactly, but it has been determined that a substantial relief of pain can be achieved if one provides means which the electrostatic charge from the area of a wound or the sensitive area of the epidermis removed. In this context, the theory was developed that protection against pain can thereby be achieved that an action on the electrostatic charge of the body through the static electricity of the environment is prevented so that the latter does not get on the nerves of an open Wound, a sore spot or an e-crack in the epidermis or the sensitive and electrostatic Charge of permeable skin over a wound that has just healed can act.

From the French patent specification 750 222 and from the USA patent specification 620 679 it is already known to remove electrical charge from the epidermis with conductive tapes or mats or fabrics placed directly on the epidermis. There these conductive tapes or mats lie directly on the epidermis and, on the other hand, the epidermis always has a certain electrical conductivity, the influence of such an arrangement is electrical Do not suppress charges on the epidermis.

It is also already known from French patent specification 1 255 797 a device which from consists of a tape or mat-shaped cover and which is placed on or over the epidermis, wherein an insulating layer facing the epidermis allows electrical charges to pass through to the epidermis prevented. A capacitor made up of several metal-paper layers is provided over the insulating layer is constructed. The whole structure is covered with a plaster-like, non-conductive layer on the outside Cover attached to the surface of the skin and has no dissipative electrical connections. S Rather, the electrostatic potential that appears in the capacitor structure is intended to be an influence applied to the epidermis.

These known devices are for the aforementioned dissipation of the electrostatic charge from a sensitive area of the epidermis and not suitable for protecting this area.

The invention is therefore based on the object of creating a protective device with which it is possible is to suppress the effect of static electricity on the sensitive area or electrostatic Discharge charge from the sensitive area of the epidermis.

Based on the protective device mentioned at the beginning, this object is achieved according to the invention.

ao solved by that the device has at least two superimposed areas, one of the Epidermis-facing isolator area that extends over the area of the wound or sensitive area extends out and prevents the passage of electrical charges to the epidermis, and one of the Epidermis side facing away from the insulator area covering the collecting area, the electrical charges collects from over at a distance from the wound or the sensitive area with the Epidermis conductively connected connections the electrical charge of the collecting area to the epidermis derive towards.

A built according to the features of the invention protection device has the advantage that it forms a barrier which is arranged over and around the wound and allows the passage of the static Cut off electricity to the wound. It is also used over the wound area or the sensitive In place of the epidermis, a surface area is created on which static electricity can collect is discharged via conductive connections. Through this

the influence of induced electrostatic charge on the sensitive area is also prevented.

Advantageous designs of the protective device described above are the subject of subclaims.

The above protective device is shown in the drawing in several exemplary embodiments.

F i g. Figure 4 shows the placement of the electrostatic shield or barrier over an associated one Wound on a finger. A bottle-shaped shield or hood is used, which the in Fig. 1 through 3 shown is similar. In this fig. 4 and in FIG. 5, a finger of the hand 24 is designated by 22. Dressing material is denoted by 26, which surrounds the finger and covers a wounded area 28 and protects.

If the electrostatic shield or barrier has been placed over the bandage, a strip may appear of electrostatically conductive, dissipative adhesive tape 30 in the longitudinal direction over the shielding body 10 can be arranged. The tape is then looped around the outer end of the shielding body, so that part of the band extends along the top and across the back of the hand, while another part of the tape runs along the underside of the shielding body 10 and the lower. or inside of the index finger extends. This conductive tape is so long that the ends fit together Extend slightly away from the shielding body, for example to the wrist, as shown here: If desired or necessary, similar conductive tape can be placed around the wrist around the ends of the longitudinal band 30, as indicated at 32 is indicated. This will not only does it ensure that the ends of conductive tape 30 are held in place, but it will the contact resistance between the band 30 and the surface of the body is improved.

Since the shield body 10 also acts as a static electricity collector, the conductive tape decreases 30, which is wrapped in the longitudinal direction around the body, the static electricity that is on the barrier or the shielding body collects. The tape 30 conducts this static electricity to the surface hand or skin. This effect is supported by the fact that a conductive tape 34 around the shielding or blocking body 10 and across the conductive tape 30.

It has been shown that polystyrene as a plastic for the production of the shielding body 10 is particularly is well suited. The conductive tapes such as 30, 32 and 34 can be made from any suitable conductive Material that is provided with adhesive. For example, you can get the desired result with an adhesive tape can be achieved, which consists of any suitable material in the electrically conductive Metal particles are embedded.

The electrostatic shield can also be made from sheet material or from a wide strip of material order. This material can be multilayered. Such sheet material is shown in FIG. 6 shown, where part of the material is turned over so that the underside is visible. This is similar to that Formed top of a waffle iron and can be referred to as a waffle iron profile. This material sheet is denoted by 36. Part of this sheet is shown in FIG. 7 shown on a larger scale. The F i g. 7th Figure 12 shows a representation of the underside of the material with the waffle iron profile of the same more clearly is switchable.

The sheet of material 36 can be multilayered. It consists of the airtight and waterproof, electrical conductive top or outer layer 38 and a second layer 40 which has the waffle iron profile shown and can be welded or glued to the layer 38. This layer 40 is spaced in rows mutually arranged, protruding parts 44 provided, which allow ventilation. the Layer 40 is made of plastic or some other waterproof material to keep body moisture

. cannot reach layer 40. By creating the two-way ventilation between the lock and the association that is shown in FIG. 9, for example, is shown and denoted by 46, it is ensured that Moisture that passes through the bandage from the finger is immediately removed.

The layer 38 consists of a suitable, waterproof, electrostatic charge collecting and dissipative rubber, plastic, or any other suitable electrostatically conductive material that is capable of is to dissipate any static electricity, similar to the conductive one described above Tape.

The layer 38 may extend over and beyond the waterproof layer 40 so that it lightly touches the surface of the body beyond the bandaged area or wound, as shown in FIG. 9 is shown. This protruding part 38 'of the outer layer is not intended to Block the flow of air to the spaces between the parts 44 of the layer 40, but rather the skin surface touch only so that a derivative is obtained.

An electrically conductive tape is wrapped around the end of the shield and on both Pages backwards to the back of the hand, for example as shown in FIG. 9 is shown. In Fig. 9 this conductive adhesive tape is designated by 48.

The shield consisting of a sheet of material 36 or a strip can also be used without the protruding Edge portion 38 'has been used. In this case, only the conductive adhesive tape 48 is used for deriving of static electricity from the conductive outer layer 38 to the body surface.

Fig. 10 illustrates another embodiment. This embodiment can be applied. when the wound or the sensitive area shielded against the static electricity is on a different part of the body than a finger or toe, for example the Surface of an arm 50 or on part of the trunk. In this Fig.10 there is an electrostatic Shield in the form of a sheet or plaster denoted by 52. This shielding can also be designed like the sheet of material 36. It can be provided over a conventional bandage, covering a wound in the surface of the skin. However, it can also be used over any other association, z. B. a plaster cast or placed directly on the skin surface, as in Fig. 11 is shown. It is important in any case that the shield extends over the circumference of the wound or extends beyond the painful or sensitive area. Here's a ripped open at 54 or wounded area of the skin and flesh. In the present embodiment, it extends the outer layer of the electrostatic shield extends beyond the inner layer and lies on the surface of the skin. In addition, conductive adhesive tapes 56 can be used which contain the

When using the plastic material with the usual gauze dressing, the electrostatic iron profile, as shown in FIGS. 6 to 9 and 11, is 35 shielding dressing. When the bandage 79 is around, the raised portions 44 are relatively rigid or coiled. The shielding dressing can be prevented by means of a hard layer so that it can hold the flattened multilayer adhesive tape 82 in place. At the same time, they allow the form of a roller 81 (FIG. 19) to be present. stand between the raised parts that the adhesive tape 82 is electrically conductive. There is shielding readily around a finger or an electrically conductive material, for example aluminum, bent around an outer layer 83 of a suitable bandage present on the finger. The same applies to the corrugated material 58 shown in FIGS. 12 to 14 or the like on the inner surface of the layer, the corrugations 60 of which 83 an adhesive coating 84 is provided,
