Description

Cover sheet for body measuring device and automatic configuration device thereof

The present invention relates to a cover sheet for use in a body measuring device or a weight scale provided with electrodes for supplying current to the body and/or for measuring a potential difference between two parts of the body.

In particular, the present invention relates to a cover sheet for a "body composition measuring device" and an automatic configuration device for the cover sheet, the body composition measuring device for measuring the impedance of the body using body impedance techniques.

More particularly, the present invention relates to a "cover sheet stock" comprising a plurality of unit cover sheets that are detachably interconnected or stacked, and with respect to cover sheet stock and openable containers (eg, for sealing storage cover sheets) A combination or kit of storage bags and boxes.

The "body composition measuring device" is understood to calculate the body fat mass or other body composition from the impedance detected between two parts of the body (for example, between the distal portions) and the physical conditions such as height and weight. And/or constructed information. The applicant of the case manufactures and sells various body composition measuring devices. A mechanism for such a body composition measuring device has been disclosed in many documents, for example, JP-A1-05-49050 (now Japanese Patent No. 1848283).

The principle of measuring body composition using impedance techniques that measure differences in conductivity over different parts of the body composition is disclosed in Keisoku Gi jutsu, "Measuring Technique", September, 2000, p. 14-20 And Nihon Rinsyo, Vol. 53, 1995 special edition, June 22, 1995, p. 179-182. The contents of the above documents are incorporated in this specification.

In the collective physical examination or health examination in which most unspecified individuals use the same body composition measuring device or weight scale, it is preferable to take measures to prevent cross-contagion. In such a body composition measuring device or a weight scale, the subject stands on bare feet, thereby increasing the risk of cross-contagion.

Furthermore, as described in the above documents, the body composition measuring device using the impedance technique is susceptible to the physical state (biological variability) of the subject. Therefore, it is preferable to prevent the subject from feeling uncomfortable or panicked. In the case of a collective physical examination or a whole body examination that forces many subjects to take measurements in turn, several subjects are reluctant to use the same measurement device after use by other subjects. In view of this, it is helpful or advantageous for the subject to know that the cleaning of the measuring device is to obtain an appropriate measurement result.

The above problems may not be as serious in the case of home use. However, when a visitor such as a friend or a relative visits and uses a body composition measuring device or a weight timer in a clean situation, it is necessary to use a cover sheet for the measuring device as an etiquette sheet.

By wiping the platform, the surface of the measuring device can be kept clean. However, in the case of a collective physical examination or a whole body examination, this must be kept clean by the operator. In addition, uneven water remaining on the surface of the gauge can cause measurement errors. In such a measuring device (for example, a body fat meter) that measures the subtle difference in conductivity of the body composition, it is difficult for the surface to be cleaned in a simple manner.

The platform of the measuring device can be covered by a simple cover sheet. However, the platform of the body composition measuring device has a plurality of electrodes (generally two or four electrodes), and these electrodes must be electrically insulated from each other. We cannot choose a covering material that will affect the impedance. In addition, we must never let a subject, such as an elderly person, slip and be injured during use. Moreover, expensive methods or materials are not acceptable in practical use.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cover sheet for a body composition measuring device using an impedance technique which can prevent cross-contamination, which can be used safely without giving a large influence on the impedance of the measurement, which ensures between the electrodes Insulation, and it can be used at low cost.

Another object of the present invention is to provide a disposable cover sheet made of a non-woven fabric which is optionally provided with an anti-slip treatment on at least a portion thereof, which is placed on the surface of the scale when in use.

Yet another object of the present invention is to provide a cover sheet stock comprising a separable side A plurality of unit cover sheets that are interconnected or stacked, and a combination or set of stock and openable containers in which the stock is sealed for storage.

Still another object of the present invention is to provide an automatic cover sheet arranging device for automatically feeding and placing a cover sheet on an electrode portion of a body measuring device.

A first subject of the present invention is a cover sheet for a body measuring device having an electrode for supplying a current to a human body or measuring a potential difference between two parts of the body, wherein the cover sheet has a body measurement corresponding to the body a conductive area portion of the electrode of the device and an insulating area portion for spacing the adjacent conductive area portion, the conductive area portion having conductivity in a thickness direction, the insulating portion being at least along The planar direction has electrical insulating properties.

In the example of the present invention, conductivity in the thickness direction (hereinafter referred to as "dry") is produced by dispersing, adhering or adding a conductive solid material to and/or in the cover sheet material. Such a conductive solid material may be conductive particles, powder or fiber.

In the example of the present invention, conductivity in the thickness direction is generated by infiltrating, adhering or absorbing the conductive liquid into and/or on the cover sheet material (this case is hereinafter referred to as "wet"). Such a conductive liquid may be an electrically conductive aqueous solution.

We can use "dry" and "wet" together. For example, a "dry" cover sheet can be coated with a conductive aqueous solution such as water.

The cover sheet material can be in the form of a nonwoven or a textile, a fiber cloth, a felt, a fabric, a knit or a film.

The cover sheet according to the present invention preferably has an anti-slip device disposed on a portion of the upper surface and/or the lower surface thereof.

The conductive area portion may be disposed on a platform of the body composition measuring device corresponding to the electrode portion in contact with the subject's foot, or in an electrode portion corresponding to the contact with the subject's hand. The location of the share.

The cover sheet according to the present invention may be made of a non-woven fabric and may be disposable. I A person can make a conductive area portion by conductive treatment.

A second subject of the invention is a disposable cover sheet which is manufactured from a nonwoven fabric and which has at least a partial anti-slip treatment.

A third subject of the present invention is a cover sheet storage comprising a plurality of unit cover sheets detachably connected in series, each unit cover sheet including a conductive area portion corresponding to an electrode of the body measuring device and An insulating area portion separating adjacent conductive area portions, the conductive area portion having conductivity in a thickness direction, the insulating area portion being electrically insulating at least along a planar direction. A preferred form of stock is in the form of a roll. The stock can be manufactured from a plurality of stacked unit cover sheets. In this case, it is preferred to continuously stack the two unit cover sheets so that the unit cover sheets can be continuously withdrawn, similar to the so-called "toilet paper" stack in the box.

A fourth subject of the present invention is a wet cover sheet stock and an openable container set for sealing the stock. Such a group is advantageous for preventing evaporation of the conductive liquid when the conductivity in the thickness direction is generated by infiltrating, adhering or absorbing the conductive liquid into and/or on the cover sheet material. In particular, such a group can be used for household storage of wet cover sheets.

A fifth object of the present invention is an automatic cover sheet arranging apparatus comprising: a cover sheet supply unit disposed on one side of an electrode of the body measuring device; and a cover sheet recovery unit which can be disposed on the opposite side or in the same manner as the supply unit side. Automatic cover sheet deployment devices are particularly advantageous where many subjects are being measured in health centers, hospitals, and general examinations. We can supply the cover sheet from the cover sheet stock in roll or stack form.

The automatic cover sheet arranging device may have a supply device of a conductive liquid. The conductive sheet portion of the cover sheet can be infiltrated, adhered or absorbed by the conductive liquid by passing the cover sheet through a bath containing a conductive liquid. The conductive liquid may also be supplied by a sponge roll through which water may be continuously supplied or the conductive liquid may be sprayed.

The "body composition measuring device" is understood to be a measuring device that can calculate information on body composition and structure (for example, body fat content) from impedance between two parts of the body and from physical conditions such as height and weight.

"Thickness direction" is understood to mean the direction from the surface to the opposite side surface of the cover sheet, and "planar direction" is understood to be parallel or nearly parallel to the direction of these surfaces.

The word "conductivity" literally means electrically conductive. The ideal state is zero resistance, but may have some degree of resistance. However, the resistance through the conductive area portion is ideally uniform.

The phrase "insulating" is understood to mean conductivity that does not affect the measurement results of the body composition measuring device using body impedance.

The phrase "having at least partial anti-slip treatment" is understood to mean a state in which an elderly person who has the greatest risk of injury uses a body measuring device or a weight to measure that the cover sheet does not slide on the body measuring device or the weight scale.

The measured values obtained by the body composition measuring device can be calibrated by using a calibration table or curve.

"Electrically conductive solid" is understood to mean conductive particles or powders which are solid when used, such as aluminum, iron, silver, and metal powders of gold or metal salts, or inorganic powders such as carbon powder, or metal fibers or carbon fibers. We can also use carbon nanotubes. In general, the conductive solid is added to the sheet material such as non-woven fabric, fiber cloth, and felt at the manufacturing stage of the cover sheet, or the conductive solid is broken into the fiber during the fiber stage, or the conductive solid is applied and infiltrated. Or spread on the surface of the cover sheet or into the cover sheet to produce electrical conductivity in the thickness direction.

"Electrically conductive liquid" is understood to mean a conductive liquid which is liquid in use and is usually an aqueous solution. The conductive liquid can be tap water (usually containing chlorine). It is possible for us to add suitable substances which increase conductivity and/or produce uniform electrical conductivity, such as agents for producing conductive ions, such as water soluble salts, such as sodium chloride. The aqueous solution may contain an agent capable of avoiding or slowing drying, such as a water retaining agent, a wetting agent, and a drying preventive agent, such as acryl amide, polyvinyl acetamide, or polyalkylene. Glycol ester). water The solution may contain other additives such as antibacterial agents, disinfectants, antimicrobial agents, deodorants, antioxidants, humectants, additives having various functions such as soothing, fresh-keeping, anti-inflammatory and analgesic properties, having, for example, mildew resistance, prevention An allergic, moisturizing, environmentally-friendly and fragrant catechin that contributes to health and beauty, and additives such as sterilized ceramics and borax, photocatalysts such as titanium dioxide, flame retardants, and the like.

"With anti-slip characteristics" is understood to mean a state in which the cover sheet does not slide on the body measuring device or the weight scale even when the elderly person who has the greatest risk of injury uses the body measuring device or the weight.

The cover sheet according to the present invention is preferably made of a nonwoven fabric or a textile from the viewpoints of strength, insulation, hygiene, safety, and cost. Non-woven fabrics are well known materials and various nonwoven fabrics are commercially available. Nonwovens can be made in a variety of different ways as well as from a variety of different materials. These materials may be: natural fibers such as cotton, hemp or bamboo fibers; animal fibers such as sheep wool, silk; chemical fibers such as enamel, cupra, acetate, polyamide, polyester Fibers, polyacrylonitrile fibers, polyvinyl alcohol fibers, polyolefin fibers such as polyethylene, polypropylene, polyvinylidene chloride, and polyurethane; inorganic fibers such as glass fibers, metal fibers, and carbon fibers. The method for producing the nonwoven fabric is also not particularly limited and any known technique such as an adhesive method, a hot melt method, an ultrasonic bonding method, a needle sticking method, a spunlace method, a needle seam bonding method, a spinning method can be used. Silk bonding method, melt blowing method, centrifugal force method, flash spinning method, voltage dry spinning method, film method, air network forming method, card method and wire mechanical method.

Since the manufacturing cost is the main factor, the cover sheet according to the present invention is preferably disposable. From this point of view, it is preferred to select a general-purpose material such as polyolefin, cotton, and a mixture of polyolefin and cotton or paper as the material of the cover sheet according to the present invention. In particular, a preferred material for use in medical devices and disposable masks, surgical abdomen and robes is a non-woven fabric of polyester/pulp having high strength and low cost.

In the cover sheet according to the present invention, the electrode corresponding to the body composition measuring device Part of the conductive area must be electrically conductive. Such a conductive area portion may be formed (1) directly from a conductive material, or (2) formed by subjecting a non-conductive material such as a non-woven fabric or a plastic material to a so-called conductive treatment. The latter's conductive treatment is suitable for mass production.

In case (1), the conductive area portion is directly formed of a conductive material, and by placing an opening in the position of the non-conductive sheet corresponding to the electrode, the conductive patch is placed on the opening, The cover sheet in accordance with the present invention is then fabricated by attaching or securing the outer periphery or edge of the conductive patch to the inner periphery or edge of the opening with an adhesive or by welding. The conductive patch can be made of any conductive material. In general, we can provide non-woven electrical conductivity or make it conductive by two methods. In the first method, the conductive material is entangled (mixed) with the material of the nonwoven fabric, and the resulting mixture is woven into filaments or fibers, and the conductive patch can be produced from the produced conductive filaments or fibers. In the second method, a commercially available nonwoven fabric is subjected to a so-called conductive treatment to produce a conductive patch. The conductive patch may have any form such as a knitted fabric, a woven fabric, a non-woven fabric, and a cover sheet. For example, the conductive patch can be made of a textile impregnated with fibers of a conductive material and a non-woven fabric or cover sheet. If the cost permits, a cover sheet or textile made of, for example, a synthetic resin in which polyamide, polyamide or acetic acid is dispersed may be used as the conductive patch. The non-conductive sheet used to form the non-conductive area portion can be made of any insulating material such as polyethylene and a polyester/paper mixture.

In the case (2), the non-conductive material is made into or becomes a conductive area portion by the conductive treatment, and a well-known conductive treatment technique can be used. The insulating area portion can be masked during the conductive process. A variety of different electrically conductive materials for this treatment are also well known, and metal powders such as powders of aluminum, iron, silver and gold, or metal salts, or inorganic powders or carbon fibers such as carbon powder are generally used. It is preferred to use a conductive filler such as carbon black, which is relatively inexpensive and suitable for mass production. In the conductive treatment, a person can cover the sheet through a pattern having a through hole corresponding to the electrode, and a solution in which the conductive material is dispersed is applied to the nonwoven fabric. We can use a compound capable of uniformly spreading a conductive material and improving the wettability of the nonwoven fabric, for example, containing A solvent (ie water, alcohol or ester) of a surfactant and a salt.

The conductive area portion and/or the insulating area portion may be made of a laminate material. For example, the upper surface of the insulating area portion may be made of a low density polyethylene film, and the lower surface may be made of a rubber or elastomer non-woven fabric. From the viewpoint of improving the conductivity in the thickness direction, although it is not preferable to form the conductive area portion in a laminated structure, the conductive area portion can be produced by a plurality of laminated thin layers. For example, the upper surface of the conductive area portion may be made of a polyamide mesh, and the lower surface may be made of a non-woven fabric of conductive polyamide. We can also use a variety of different combinations of layers, such as a combination of antibacterial non-woven/bacterial impervious nonwovens or a combination of textiles/non-wovens.

The cover sheet according to the present invention may contain other additives such as an antibacterial agent, an antimicrobial agent, a deodorant, an antioxidant, a moisturizer, a soothing agent, a preservative, an anti-inflammatory agent, an analgesic, or an anti-mold property and an allergy-free Effects, moisturizing effects, and environmental atmosphere improving effects, such as catechin additives, sterilized ceramics and borax, or photocatalysts such as titanium dioxide, and fire retardants, which contribute to health and beauty.

At least a portion of the upper surface and/or the lower surface of the cover sheet according to the present invention preferably has anti-slip properties. In particular, the sliding between the cover sheet and the platform is not ideal for safety. When the cover sheet according to the present invention itself has an anti-slip property, it can be safely used without performing anti-slip treatment on the platform. For example, the anti-slip treatment can be disposed on the platform by partially attaching the amine ester film, and in this case, the cover sheet according to the present invention having anti-slip characteristics can be used more safely. The anti-slip properties can also be imparted by the properties of the material itself. In fact, the material such as polyurethane can itself be a non-slip cover sheet. In the case where the nonwoven fabric is made of polyethylene, polyester or a mixture thereof with cellulose, it is preferred to achieve an anti-slip treatment on at least a portion of the surface of the cover sheet, preferably on the entire surface of the cover sheet. Anti-slip treatment is achieved. Such an anti-slip treatment can be accomplished by any well-known technique, such as a natural pattern or a synthetic rubber material, an elastomer, a rubber or an adhesive, in a desired pattern such as a dot pattern and a straight line pattern. The anti-slip treatment can be done on the entire surface of the cover sheet and provides such treatment that does not affect the measurement.

In the case of using a continuously fed roll stock cover sheet, when the cover sheet is fixed by the supply unit and the recovery unit in the automatic setting device, the anti-slip treatment can be omitted or reduced.

Preferably, the conductive area portion is marked or marked on the cover sheet according to the present invention, so that the operator, the user or the examinee can easily recognize or confirm the position of the conductive area portion at a glance, without In the case of a mistake, align it with the electrode portion of the measuring device. For this purpose, it is preferred to print the frame (window) on the conductive area portion. Further, it is preferred to indicate the alignment position, for example, to indicate the center mark and the straight line of the installation position. For example, a foot mark can be printed on a cover sheet in accordance with the present invention to assist in the placement of the foot.

Hereinafter, the actual use of the cover sheet according to the present invention will be described with reference to the accompanying drawings.

1 is an exemplary plan view of a cover sheet (1) in accordance with the present invention, and FIG. 2 is an exemplary cross-sectional view taken along line A-A and line B-B of FIG. The cover sheet (1) comprises: a conductive area portion (2) corresponding to the electrode portion of the body composition measuring device; and an insulating area portion (3) separating the adjacent conductive area portions (2) . The conductive area portion (2) must have conductivity in the thickness direction (the bottom-up direction in Fig. 2). The insulating area portion (3) must have insulating properties at least in the planar direction (the plane in Fig. 1). A rubber non-slip point (4) is formed on the lower surface of the cover sheet (1).

Figures 3A and 3B show an embodiment of how the cover sheet (1) is used on a body composition measuring device (10) using impedance techniques. The body composition measuring device (10) of Fig. 3A is a multi-frequency body composition measuring device for measuring body fat percentage, muscle mass, body water, and body weight. In use, the subject stands on the platform (11) and holds the microphone (15) to display the various materials described above. The platform (11) has an electrode portion (12), four portions in the drawing, and an insulating portion (13) separating the adjacent electrode portions (12).

The cover sheet (1) shown in Fig. 3B in accordance with the present invention can be used to prevent cross-contagion via the platform (11) and/or the microphone (15). The anti-slip treatment on the lower surface of the cover sheet (1) allows the person on the cover sheet (1) to be safe from slipping.

4A and 4B show the basis for a home or home body composition measuring device An embodiment of a cover sheet (1) according to the invention. The reference symbols used in Figures 4A and 4B are the same as those used in Figures 3A and 3B. In Fig. 4A, the planar fastener (14) is secured to the body assembly measuring device by double-sided tape. In use, the cover sheet (1) made of non-woven fabric is pressed against the flat fastener (14), and the cover sheet (1) can be firmly fixed. In the family-type body composition measuring device, for the family member, the same cover sheet can be repeatedly used without replacement until it becomes dirty, so in most cases, due to the use of the flat fastener (14) The work of replacing the cover sheet is not troublesome.

Figures 5A and 5B show a variant embodiment of a cover sheet (1) according to the invention. In Fig. 5A, the insulating area portion (3) is made of a laminate. For example, the upper insulating area portion (31) may be made of a low density polyethylene cover sheet, and the lower insulating area portion (32) may be made of an amine ester cover sheet. The materials of the upper and lower insulating area portions (31 and 32) may be selected from various plastic materials, papers, and elastomers in consideration of cost, strength, workability, and other factors. These materials can have any desired morphology, such as non-woven fabrics, textiles, cover sheets, and films. The conductive area portion (2) may also be made of various materials similar to the insulating area portions (31 and 32), and provide a conductive area conforming to such a demand for conductivity in the thickness direction.

Figure 5B shows a more simplified variation of the cover sheet (1) without the underlying insulating area portion (32) shown in Figure 5A. The outer peripheral edge of the conductive area portion (2) is fixed to the insulating area portion (31) by an adhesive or by welding.

6A and 6B are schematic views of another modified embodiment of the non-woven cover sheet for the home or household body composition measuring device shown in Figs. 4A and 4B. In order to make the figure clear, the scale is enlarged in the thickness direction. Fig. 6A is a perspective view, and Fig. 6B is an exemplified cross-sectional view taken along line C-C of Fig. 6A. In this embodiment, the conductive area portion (2) can be fabricated by providing or processing electrical conductivity to a corresponding portion of the nonwoven fabric. In the cover sheet (1), the window (5) is manufactured at a position corresponding to the meter portion in the home body composition measuring device shown in Figs. 4A and 4B, and the measurement data can be read without difficulty. The window (5) can be covered by a transparent cover sheet. We can print the mark (6) to indicate where the foot is placed. These marks can be marked left, right, up and down The direction. Alternatively, we can print the foot mark so that the cover sheet (1) will not be placed in the wrong position and/or direction.

7A, 7B and 7C show a microphone cover (40) for the body composition measuring device shown in Figs. 3A and 3B. Fig. 7A is a rear view of the microphone (15), and Fig. 7B is a front view thereof. The microphone (15) has two electrodes (16 and 17) separated or isolated by an insulating portion (18). The microphone (15) is connected to the body composition measuring device (10) via a wire (19). In use, the subject standing on the platform (11) holds the microphone (15) and the electrodes (16 and 17) function as hand electrodes.

Figure 7C shows the microphone cover (40) mounted on the microphone (15). The microphone cover (40) can be embedded in the microphone (15) by the free end on the opposite side of the wire (19). Conductive area portions (41 and 42) are formed at positions corresponding to each of the microphone covers (40). In the drawings, the microphone (15) has a square appearance in the cross section, and when the microphone cover (40) is only embedded in the microphone (15), since the microphone cover (40) has a three-dimensional shape corresponding to the microphone (15), The conductive area portions (41 and 42) can be placed at appropriate positions corresponding to the electrodes (16 and 17).

In another variant embodiment (not shown), the microphone cover can be a simple cover sheet as shown in Figures 4A and 4B. Such a cover sheet can be wrapped around the microphone (15) and secured in place on the microphone (15) with a planar fastener (not shown).

By placing the cover sheet according to the present invention on a simple scale without electrodes, the cover sheet can be used as an antifouling paper or an etiquette sheet.

The cover sheet according to the present invention can be used individually by the person in the form of a unit cover sheet, however, it is more convenient for the user to supply the cover sheet in a detachable manner in which a plurality of unit cover sheets are connected in a string.俾 Allows the user to extract unit cover sheets from the stock when needed. The stock may be in the form of a roll in which a plurality of unit cover sheets are joined and wound, or in a stack form similar to a so-called "toilet paper" box in which a plurality of unit cover sheets are stacked in a partially nested manner. , 俾 enables continuous two-unit cover sheets to be extracted without interruption.

In the case of a wet cover sheet, the manufacturer supplies the stock in the form of a stock and a set of containers for sealing the package therein, so that the user can use the user until use. The state of the package can be preserved while the wet cover sheet is prevented from drying. The container may alternatively have a moisture barrier layer and a plastic bag or box having an opening through which the cover sheet can be withdrawn.

Figures 8 and 9 show two embodiments of a container pack comprising a cover sheet stock and a package for packaging the stock in accordance with the present invention.

In the case of Fig. 8, a plurality of unit cover sheets (1') are alternately stacked in a nesting manner similar to the so-called "toilet paper", so that two consecutive unit cover sheets can be taken out without interruption. A stack of unit cover sheets (1') is stored in a soft plastic bag (50) having a moisture barrier layer. Fig. 8 shows a state when the front end (11') of the unit cover sheet (1') is taken out from the opening (52) formed in the bag (50). To avoid drying of the wet cover sheet, a suitable cover (not shown) can be joined or welded around the opening (52).

In the case of Fig. 9, a plurality of unit cover sheets (1') are detachably connected in a string and wound in the form of a roll stock (60). The stock (60) is stored in a plastic container (61) such as a plastic case. We can make, for example, a perforated disassembly line or a detachable line (not shown) between successive two unit cover sheets. When the stock (60) is placed in the plastic case (61), the user can rotate the cover (64) about the hinge (63). In order to guide the center (65) of the roll stock (60), a guide groove (not shown) may be formed on the inner surface of the plastic case (61). The gasket can be placed at the outlet of the plastic box (61) and can be withdrawn through the front end of its roll stock.

The cover sheet of the present invention can be automatically placed or mounted on the electrode area of the body measuring device by using an automatic cover sheet arranging device. Automatic cover sheet deployment devices are particularly advantageous when many subjects are being measured in health centers, hospitals, and general examinations. The automatic cover sheet arranging device may have a cover sheet supply unit disposed on one side of the body measurement device, and a cover sheet recovery unit on the opposite side.

The automatic cover sheet arranging device preferably has a supply unit and a recovery unit for the cover sheet. The supply unit is provided with (a) a cassette for storing stock in a roll form or in a stacked form, and (b) means for extracting the cover sheet from the stock (e.g., drive means and introducer). The recycling unit is provided with (c) for extracting the supplied cover sheet from the supply unit A drive device (such as a drive device and an introducer) and (d) a recycling box for covering the sheet. The automatic cover sheet arranging device preferably has means for controlling or synchronizing the operation of the supply unit and the recovery unit, a switch for starting the supply operation of the cover sheet, and a display for displaying the operation condition.

The automatic cover sheet arranging device may have the following optional devices: (e) a sensor for detecting conductivity, a resistance meter (generally disposed on the side of the supply unit); (f) for placing the cover sheet in the body amount An indexing device at an appropriate position on the electrode area of the measuring device (such indexing can be a mark printed on the cover sheet for optical detection); (g) for temporarily fixing the cover sheet to the non-slip a device on the electrode area of the body measuring device; and (h) a device for supplying water or moisture (in the case of a wet cover sheet).

The automatic cover sheet configuration device in accordance with the present invention can be used in conjunction with or in conjunction with any existing body measurement device without modification or alteration of existing measurement devices.

Figure 10 is an exemplary perspective view of an example of an automatic cover sheeting device in accordance with the present invention. Figure 10 is a partial cross-sectional view showing the inside of the housing removed to show the inside of the device. Figure 11 is a variation of the embodiment of Figure 10.

The automatic cover sheet arranging device shown in Fig. 10 has a supply unit (A) for covering sheets and a recovery unit (B). The two units (A, B) are connected by a connecting plate (C) for fixing the relative positions of the units (A, B). In order to facilitate the adaptation of the automatic cover sheet arranging device to the existing body measuring device, the supply unit (A), the recovery unit (B) and the connecting plate (C) can be combined by a simple connecting device such as a bolt or a clamp (no display). In one.

The outer casing of the supply unit (A) contains a container (70) of stock (60) and a container lid (71) which are connected by a hinge (72). In use, the user is only required to open the container lid (71), insert a new roll stock (60) into the container (70), pull the front end of the cover sheet from the stock and place the cover sheet in the body mass. The platform (11) of the measuring device (10) is then closed with the container lid (71). The extracted cover sheet will be clipped by The upper pressing roller (73) supported by the container cover (71) is interposed between the upper pressing roller (73) supported by the container (70). These pressure rollers (73, 74) can be used as terminals for conductive sensors or resistance meters. We can use a mechanism that vertically drives the pressure rollers (73, 74), which can amplify the gap between the pressure rollers (73, 74) as the cover sheet advances, and by the pressure rollers (73, 74) during the measurement phase. The cover sheet is clamped to prevent the cover sheet (1) from sliding.

The recovery unit (B) basically has the same mechanism as the supply unit (A). In the case of the recovery unit (B), we must provide a drive device (such as an electric motor) for pulling out the cover sheet (1) or for rotating the central axis of the cover sheet (1), and for centering the shaft A mechanism that is connected to the drive unit. Preferably, another drive device is also provided in the supply unit (A) and the operation of the two drive devices is synchronized.

In the outer casing of the supply unit (A) and/or the recovery unit (B), we can provide various components or mechanisms (no display), such as a guide for the central shaft, a conductive sensor or a resistance meter, a supply mechanism, A drive for the pressure roller (73, 74) and a computer (such as a control panel) for controlling all movements in the automatic cover sheet configuration device. For the sake of clarity, these components are not shown in the drawings.

The automatic cover sheet arranging device shown in Fig. 10 can be used for both wet and dry cover sheets. In order to avoid drying of the wet cover sheet, it is preferred to maintain the container lid (71) in the closed position.

Figure 11 is an exemplary perspective view of another embodiment of an automatic cover sheet configuration apparatus in accordance with the present invention, and is a variant embodiment of Figure 10. In the disposition device of Fig. 11, a supply device of a conductive liquid such as water is added to the disposition device of Fig. 10. In Fig. 11, the outer casing shown in Fig. 10 is not shown for the sake of clarity. For example, a conductive liquid (79) of water is supplied to the plate (77). We can supply water from a portable sink (not shown) provided in the outer casing of the supply unit (A). The water in the plate (77) can be maintained at a predetermined height.

Fig. 12 and Fig. 13 show still another type of cover sheet arranging device which is designed to be a household type by simplifying and reducing the size of the arranging device of the supply device provided with the conductive liquid (e.g., water) shown in Fig. 11. 12 and 13 are exemplary cross sections of a supply device for a conductive liquid, and the same reference numerals designate the same or similar parts.

The supply device for the conductive liquid shown in Fig. 12 is designed, and the supply unit (A) of Fig. 11 can be used alone. The container lid (71) has a handle (no display) to facilitate its transport or increase its portability. In use, the user opens the container lid (71), inserts a new roll stock (60) into the container (70), withdraws the front end of the cover sheet (1) and passes it through a guide roller (78) immersed in water. Underneath, then close the container lid (71). The person can cut the pulled cover sheet (1) along the perforation and place the separated cover sheet on the platform (11) of the body measuring device as shown in Figures 3B and 4B.

In Fig. 13, water is not supplied to the tray (77), but is supplied to a water supply roller (80, 81) such as a sponge roller to avoid overflow of water. The supply of water from the water tank (83) to at least one of the sponge rolls can be supplied by the supply controller (82). A shallow pan (84) is provided to recover excess water that has dripped.

Such an enclosure also has a handle (no display) to facilitate its transport or increase its portability. In use, the user opens the container lid (71), inserts a new roll stock (60) into the container (70), withdraws the front end of the cover sheet (1) and passes it under the sponge roll (80). Then close the container cover (71). In order to facilitate the replacement operation of the roll stock (60), it is desirable to have such a design that the front end of the cover sheet (1) can be passed under the sponge roll (80) when the container cover (71) is closed. In the case of Fig. 13, the person cuts the pulled cover sheet (1) along the perforation, and places the separated cover sheet on the platform (11) of the body measuring device as shown in Figs. 3B and 4B.

The cover sheet arranging device shown in Figs. 12 and 13 is particularly suitable for a wet cover sheet for home use, but can also be used for a dry type.

Figure 14 is a variation of the cover sheet shown in Figure 5 and is primarily used in wet mode. Such a cover sheet according to the present invention has a three-layer structure. For example, the nonwoven fabric (20) is sandwiched between opposing facing cover sheets (31, 32) of an insulating material such as low density polyethylene. The person presses the areas corresponding to the conductive area portions (2) of the surface covering sheets (31, 32) to form openings, and the non-woven fabrics (20) are exposed at these openings (stamped areas). The difference from the cover sheet of Fig. 5 is that the non-woven fabric (20) does not receive the conductive treatment. That is, the cover sheet of Fig. 14 is used in a wet type, and for example, In use, the conductive liquid is applied, sprayed or adhered to the conductive area portion (2) to produce conductive characteristics. In fact, the sprayed conductive liquid imparts conductivity only in the thickness direction. The non-woven fabric (20) can be attached to the surface covering sheets (31, 32) of the low-density polyethylene by an adhesive or welding.

If necessary, the insulation of the surface covering sheet of the low-density polyethylene can be ensured by the treatment of not allowing the conductive liquid to penetrate into the other portion of the conductive area portion (2) in the nonwoven fabric (20). For example, a region for preventing penetration of the conductive liquid may be disposed in a center line or a region of the nonwoven fabric (20). In fact, the waterproof line can be coated or welded to the nonwoven fabric (20) along the longitudinal centerline, or the material of the nonwoven fabric (20) can be replaced with a water impervious or waterproof material along the longitudinal centerline or region. In the same manner, a similar treatment for preventing the conductive liquid of the cover sheet (1) from penetrating in the lateral direction (the direction from bottom to top in Fig. 14) can be realized.

Even if the surface covering sheets (31, 32) contain a small amount of conductive liquid, there is no serious problem. In fact, the distance between the electrodes in the planar direction is considerably longer than the thickness, and the surface covering sheets (31, 32) in the planar direction can have high resistance and do not affect the measurement. If necessary, a calibration table can be added to the measurement circuit.

Figure 15 is an exemplary cross section of a device for applying, spraying or adhering a conductive liquid to the cover sheet shown in Figure 14. In FIG. 14, the same reference numerals designate the same or similar parts as those shown in FIG. 12 and FIG. The difference from Fig. 13 is that the feed water roller is replaced by a nozzle (85). A pattern plate (not shown) having a perforation pattern corresponding to the conductive area portion (2) may be disposed between the cover sheet (1) and the nozzle (85) to enable a spray of a conductive liquid such as an aqueous solution ( 86) is limited to the conductive area portion (2). We can also synchronize the spraying timing with the supply speed of the cover sheet, and use more than two nozzles or set the nozzle on the opposite side of the cover sheet.

The apparatus shown in Figures 12 and 13 can also be used to effect application, attachment or spraying of a conductive liquid on the nonwoven fabric (20) shown in Figure 14.

Hereinafter, embodiments of the invention will be described.

example Example 1

On the cover sheet (3) of the low-density polyethylene, four square openings were formed at positions corresponding to the area portion "2" of Fig. 3, each opening having a size of 13 mm × 13 mm. Four square conductive sheets (2) of 15 mm × 15 mm were cut out from a conductive non-woven fabric (thickness of 0.3 mm) composed of commercially available polyester/paper in the thickness direction. Fixing the outer periphery of each of the square conductive sheets of the conductive non-woven fabric (2) on each square opening of the cover sheet (3) of the low-density polyethylene with an adhesive or a heat seal, thereby obtaining according to the present invention The cover sheet of the structure shown in FIG. The square patch of the conductive non-woven fabric (2) has a resistance value in the thickness direction of from 400 to 500 ohms.

The platform of the body composition measuring device of the model MC-180, which can be purchased from the applicant of the present application, is covered with such a cover sheet to measure the body fat of the subject. For comparison, information on no cover sheets was also obtained. We can eliminate the difference in measurement results obtained when using the cover sheet and when not using the cover sheet by generating compensation for the obtained data.

Example 2

A square patch of the conductive non-woven fabric (2) was replaced with a commercially available conductive polyurethane foam sheet (having a thickness of 5 mm when not compressed; and a thickness of 0.3 mm by compressing 40 kg), and the same operation as in Example 1 was repeated. The resistance value along the thickness direction of the square conductive fabric (2) is several ohms.

The cover sheet can be evaluated by the same method as in Embodiment 1. In this case, the results of the measurements can be used without compensation.

Example 3

A textile made of polyamide fibers was used as a square patch of the conductive non-woven fabric (2), and the same operation as in Example 2 was repeated. The resistance value along the thickness direction of the square conductive fabric is several ohms.

The cover sheet can be evaluated by the same method as in Embodiment 1. In this case, the results of the measurements can be used without compensation.

Example 4

A cover sheet according to the present invention is produced by subjecting a polypropylene nonwoven fabric to a conductive treatment.

In the manner in which the conductive coating penetrates the polypropylene nonwoven fabric from top to bottom, the conductive coating is applied to a defined area of the commercially available polypropylene nonwoven fabric corresponding to the conductive area portion of FIG. The conductive coating is produced by mixing 100 parts by weight of ground silver powder, 1000 parts by weight of acrylic resin, and 3000 parts by weight of toluene for 10 minutes, the ground silver powder having an average particle diameter of 50 μm and by having The apparent density of 0.03 g/cm ³ was obtained by crushing a silver foil having an average thickness of 0.2 μm. We applied this conductive coating to a polypropylene non-woven fabric and passed the fabric from top to bottom. The specific resistance measured after drying has an excellent conductivity value as 7 × 10 ^-4 Ω-cm.

The cover sheet can be evaluated by the same method as in Embodiment 1, and it is found that the result of the measurement can be used without compensation.

The non-slip point of the rubber is printed on the lower surface of the insulating area portion (3) of the non-woven fabric (the diameter of the dots is about 1 to 3 mm, and the interval between the dots is 1 cm). When the obtained cover sheet is placed on the platform (11) of the body composition measuring device (10), we do not observe the slip.

Example 5 Household wet cover sheet

A non-woven patch (13 mm × 13 mm, 1 mm in uncompressed condition) and an insulating area by which the conductive patch (2) shown in the cross section of Fig. 5 is used, and the pulp is blended with the pulp. A portion (31, 32) of a film of low density polyethylene (having a thickness of 15 to 40 μm) was used to produce a roll stock (60) of the cover sheet according to the present invention. The outer periphery of the patch is thermally fused to the inner periphery of the opening made in the low density polyethylene film.

The cover sheet produced by us is immersed in a water-retaining agent, an antibacterial agent and a fragrance. In the aqueous solution of the material, hydrazine can make the mash-pulp blend fabric absorb the solution. The water remaining on the low density polyethylene film is removed by passing the cover sheet through a suction roll. The cover sheet is then wound into a roll stock.

The rolled stock (60) has a width of 430 mm, a length of about 27 m, and a unit cover sheet (1') equivalent to one hundred sheets (each having a size of 430 mm x 450 mm). A hand tearable perforation is formed between successive two unit cover sheets.

The enthalpy of the absorbing solution - the pulp-blended non-woven patch shows almost zero electrical resistance.

Example 6 Wet cover sheet for whole body examination

The same process as in Example 5 was used to produce a roll stock (60) of the wet cover sheet. However, in this case, the tearable perforation is not formed since the cover sheet is not cut. The space between two consecutive unit cover sheets (1') (430 x 450 mm) is lowered. The total length of the hundred unit cover sheets is 450m.

The resulting roll stock can be used without problems in the automatic cover sheeting device of the cover sheet shown in FIG.

It is to be understood that the invention is not limited to the embodiments described above, and those skilled in the art can make modifications, changes and variations to the embodiments without departing from the scope of the invention.
