Description

Article for adsorbing liquids The invention relates to an object for adsorbing liquids, which the liquids in holds in an immobile state. The item can be used for diapers, menstrual pads, Receiving containers for urine and the like can be used.

The diaper problem has been addressed through development of disposable diapers. These paper diapers have the same disadvantages as Fabric diapers. Immediately after urinating, they get soaked, and so is the urine splits off ammonia.

A diaper rash occurs as a result of the ammonia formed, that comes into contact with the sensitive skin of the toddler. A longer one Contact of urine and inflamed skin can promote secondary bacterial infections, because urine encourages the growth of bacteria. In either case, the diaper is wet uncomfortable and smelly and the child howls after a change. Plastic panties protect the bed, but not the child. Promote because of their impermeability Plastic panties softening the child's skin. A diaper that the Holds urine throughout the night so that it is on the contact surface between the diaper and skin as little moisture as possible would reduce the discomfort to decrease; the possibility of skin inflammation with the following complications would be be reduced. That would of course be good for the child and for the parents at Have items used during menstruation, such as sanitary napkins and cotton balls about the same disadvantages as diapers in that they become soaked and smelly. The pressure on a saturated tissue from body movements squeezes the fluid out, with the uncomfortable result of a basin, what a discerning woman means a misfortune. Bags in particular have a limited capacity for the intake of menstrual blood.

It is very difficult for people with an artificial opening for the Urine. The urine must exit through an artificial opening and be collected, The device required for this is difficult and inconvenient to accommodate and difficult to handle; The urine passes from the stoma into a bag, either directly, as described, for example, in U.S. Patent No. 3,055,368 or indirectly through a flexible hose. These bags slosh when you move of people. It is also difficult to attach them to the stoma in a leak-tight manner. Some Exercise and some sports can be difficult or impossible for such patients At night the patient is tied to the bed because of the bag deeper than the kidneys must be. This means that the receptacle for Either frame the urine on the bed or attach it to the floor near the bed have to be. The backflow of urine into the body through the stoma must be avoided, to avoid secondary damage to the kidneys from back pressure and urinary retention. A to and fro and a turning around in sleep is also common in such persons not possible.

In any position, the wearer must ensure that he is holding the bag does not hit it, otherwise it can break or the urine through the stoma into the body is pushed back. It has already been suggested to eliminate these difficulties to overcome that one to Absorption of the liquid adsorptives Material used. This is either very extensive, difficult or one of a kind small capacity, or it releases the liquid under pressure, e.g. through weight of the body leaning against a surface in the same way as from one damp sponge when squeezing water escapes.

One object of the invention is an article that contains liquids can and then keep these liquids immobile.

Another object of the invention is a * receiving container for a surgically made ureter that picks up the fluid and picks it up a larger area of solid adsorbent is distributed. This will make the Liquid immobile, so that complete freedom of movement for the wearer is made possible.

Another object of the invention is one that can be used overnight Diaper that kept the child relatively dry during this time Yet another object of the invention is a menstrual item having a large capacity that prevents the liquid from leaking out under body pressure.

Another object of the invention is a coating over a weeping Wound that rarely needs to be replaced.

Another object of the invention is a pad that fits into the brassiere a nourishing mother can be inserted so that it absorbs leaking milk and prevents soiling of clothing.

Another object of the invention is an insole for drying of the foot.

Another object of the invention is an industrial cleaning cloth that its shape does not change and even after the adsorption of liquids its solid Maintains character.

Another object of the invention is a surgical mask.

Another object of the invention is a pad for weeping rashes and other exudates.

Other objects of the invention will appear from the following description.

Fig. 5 is a cross section through a diaper according to Fig. 4, along the Level 5-5, showing the layer of fabric.

The object according to the invention for adsorbing liquids contains fiber material for distributing the liquids by capillary action Solid adsorbent for the liquids, which is used when the liquids are adsorbed retains its solid form and does not allow liquids to escape even under pressure, and an envelope impermeable to liquids with inlet openings for the Liquid to the fiber material.

Figures 4 and 5 show a diaper according to the invention. Fiber material 10 distributes the fluid, such as urine, by capillary action and promotes it the adsorption units 12 and 14. Each adsorption unit 12 and 14 consists of a package of solid adsorbents, one of which is permeable to liquids Material 20 and 22 are encased, for example by paper, a soluble plastic film, a non-woven fabric and the like.

The fiber material 10 and the adsorption units 12 and 14 are encased of a liquid impermeable film 26.

In the Porm shown, the casing 26 consists of two layers 28 and 30, which are connected to one another at the edge 32. The animals layer 32 has inlet openings for the liquid to enter the fiber material 10. In the shape shown, the inlet openings consist of numerous holes .34 in layer 30 placed where urine enters the inside of the diaper to be passed to the fiber material, from where it is then to the adsorption units got.

For the better well-being of the child, the layer 30 is covered with a fabric 36, which is shown in FIG. 5 alone.

The fabric 36 covers at least that part of the layer 26 which otherwise it would come into contact with the child's skin pictured The entire top layer 30 is covered with the fabric 36. The fabric 36 can usually consist of a fabric or paper. In any case, must it must be such that there is rapid passage of the liquid to the Holes 34 permitted.

The casing 26, the fiber material 10 and the adsorption units 12 and 14 form an elongated collapsible article that is in contact can be brought with the human body, as here the diaper with the child.

No fasteners are shown in the figures. Therefor but there are numerous known options. For example, Nan can preferably use adhesive strips or use snap fasteners to fasten the diaper.

The layers 28 and 30 must be impermeable to liquids. Such impermeability is of course only for the intended period of use necessary. For example, assuming a diaper was worn for 8 to 12 hours is to be, the film must be during this period, plus a certain amount of time Security factor, to remain impermeable to liquids and foldable. It is Clearly, these films are made from various synthetic and natural fabrics could be. Examples of synthetic materials are polyethylene, polypropylene, polyvinyl acetate, synthetic rubber and the like. Examples of natural substances are rubber and gutta-perche. Polyethylene is a preferred material.

Any material that contains liquids can be used as the fiber material 10 can distribute by capillary action. Of course, this material must be resistant to the chemical action of the liquid to be distributed, at least for the duration of the intended use. The fiber material can also be used as Wick can be referred to. Natural or chemically modified cellulose fibers can can be used for this purpose. It has been found that # glass fibers are properly arranged are an excellent wick material. As a rule, glass fibers are used in the form of mats. But you can also wicks through long, closely spaced and Form threads arranged in parallel. The use of fiberglass as a wick is im are described in detail in U.S. Patent No. 2,477,403.

A preferred fiberglass is Refrasil, available from H.I. Thompson Company is distributed. Refrasil glass fibers are made from a glass with a height Made of silicon oxide content. The fibers are made with acid leached, creating a porous and slightly acidic surface. In these Fibers does not contain any lubricant. Such fibers are particularly suitable for Treating urine and other fluids that contain solutes. These solutes are apparently adsorbed on the surface of the fibers.

Figures 4 and 5 show packages made of liquid permeable Material enveloping the solid adsorbent.

The material permeable to liquids is preferably made of Paper. It is not necessary that this material be after soaking Retains strength as most powdered adsorbents are in place remain after adsorbing liquids. In some cases it can material permeable to liquids also made of a water-soluble film, e.g. made of polyvinyl alcohol.

The solid adsorbents are characterized in that they retain their solid form and not the absorbed liquid even under pressure let out. Such "solid" substances are real pests, gels and resins called, which soak up water and remain firm in the process. The ability to look after the Adsorption of liquids to maintain their solid form means that the appearance of the solid adsorbents remains relatively unchanged. This expression but can of course only be used in a proportional sense. Of course It does not refer to such cases when the amount of liquid knows the adsorption capacity the adsorbent exceeds.

The adsorbents must hold back the adsorbed liquid, when pressure is applied to them. In other words, they must be the adsorbed Immobilize liquid.

A wet sponge does not immobilize the water, because when pressure is applied the water escapes him. The pressure to be withstood obviously depends on the intended one Use of the item.

In general, it is sufficient that the adsorbent has one Endure pressure from normal body movements or from an accidental bump is produced.

The solid adsorbents can be granular or powdery solid material such as activated carbon, silica gel, activated aluminum oxide, puller earth, Diatomaceous earth, carboxymethyl cellulose, derivatives of guar, natural and synthetic Resins, bentonite and the like.

A particularly preferred solid adsorbent material is that of Micro-Cel E sold by the Johns-Manville company. This is a finely divided powder, that by hydrothermal conversion of diatomaceous earth and lime is won. It is described as a synthetic, hydrous calcium silicate. Mikro-Cel E adsorbs 3-4 times its weight in liquids and remains here @ a dry, free-flowing powder.

The solid adsorbents can also be porous, organic contaminants or organic fibers. Strands of grains of cellulose acetate, -as they are e.g. Used as filters in cigarettes are particularly good adsorbers for the objects of the invention. These organic adsorbents are self-supporting and can be shaped so that wrapping is not necessary.

The diapers according to FIGS. 4 and 5 can also be easily modified so that that they can be used as sanitary wipes. In this case one can usually add deodorant and medicinal substances. The high adsorption capacity of the Fiber material and the adsorbents allow these additional ones to be added Substances that contribute to the peace of mind of the wearer.

FIGS. 1 to 3 show an embodiment of a receiving vessel for urine from an ileostomy. The object of Fig. 1 has an elongated, ribbon-like Shape and is so pliable that it can be wholly or partially around the human body can be looped. Fig. 1 shows a receptacle with a length about 75 cm, a width of about 12.5 cm and a thickness of about 1.25 cm. The receptacle can hold the urine that is released from an adult during is eliminated half a day and only needs to be changed about twice a day will. FIGS. 2 and 3 show the same object on a roughly doubled scale. The thickness of the container is enlarged in FIGS. 2 and 3 for the sake of clarity.

In Pig.2 and 3, 50 and 52 mean the skin of the wearer for the ileostomic container 54. In FIG. 3, the stoma 56 is also shown.

The container 54 contains a plurality of elongated fiberglass wicks 60, 60a, 62, 62a, 64 and 64a, which are arranged longitudinally in the container 54. The liquid from the stoma 56 is received by a plug 68 made of glass fibers. The stopper 68 contacts a fiberglass manifold 70 which carries the liquid to the wicks 60 to 64a conducts.

The packets 74, etc. of solid adsorbent material are all inside of the container 54 in close contact with the wicks 60 to 64a. Of clarity Because of this, only a single package is marked with a number in the Piguren. It is clear that the size of the packages depends on the dimensions of the belt-shaped Container 54, on the number of wicks, on the type of solid adsorbent material and the manufacturing process.

As shown, the packages are 64 elongated units that consist of consist of the above-mentioned calcium silicate and are wrapped in paper.

According to Figures 1 to 3 are the wicks and the adsorption units encased in two layers of polyethylene, an outer layer 78 and one dem Body adjacent layer 80. Both layers are welded at the edges 82, so that they form a container impermeable to liquids.

Bie layer 80 has an entry opening 86 for the entry of the liquid from the stoma 56. The opening 86 is at the depicted form of training Reinforced by means of a square 88 made of polyethylene. As the drawings show the container should be worn directly on the skin, with the entry opening for the liquid is attached directly to the stoma. Funding can also be provided to seal the opening 86 to and through the skin around the stoma leakage of fluids during physical activity on the part of the wearer to prevent. A particularly effective arrangement of this type using pressure sensitive adhesives are described in U.S. Patent No. 3,055,368, Fastening means for the container 54 are not shown, since such on the Hand lying. One can, for example, provide a push button that fits into push buttons on a elastic band can engage, so that the container fits the body of the Wearer can customize.

The container is inconspicuous when carried and prevents sloshing the liquid and can be independent of the position of the wearer or the vehemence his movements are carried. You can even use such a container while swimming wear what was not possible with the previously known devices.

Various modifications to the diaper and ileostomic container can of course be provided. The invention is not intended to be limited to the specifically illustrated embodiments.
