ABSTRACT:
FIELD OF THE INVENTION
The invention relates to a panty-like type absorbent diaper destined for repeated use and provided for that purpose with a changeable absorbent pad. The diaper pants comprise a front part, a back part and a crotch part with an absorbent pad, while the front and back parts are extended to side portions with fastening means.
BACKGROUND OF THE INVENTION
The multipurpose diaper panties with an absorbent body have been known, being repeatedly used either as a commonly worn underpants or serving as a diaper. The body liquids are absorbed in the same manner as in a common diaper case, but the panty-like pants serve further to its user in an intact condition until the time and an opportunity come to replace the soiled panty-like diaper with a clean diaper. As the user is to have a feeling of wearing underclothes, it is important that the panty-like diaper is of a panties shape, e.i., the article with a waist and leg openings, not a pants form with fastening tabs connecting during application the diaper front and back parts. As well as the outer casing layer materials for the panty-like diaper are selected such that above all the adult users are spared of psychologically negative feelings during wearing a diaper with a plastic outer casing layer.
In case the panty-like diaper is worn by children (babies) other problems occur upon the basis of a fact that a fair number of children suffer from hip joints deformations, e.g., dysplasia, and on that reason they have to wear for a longer period health aids for their treatment. For that purpose greater number of diapers have been commonly used instead of a usual single diaper, but that brings about difficulties with diapers displacement and their deflection from a desired position between children's thighs during wear, or special therapeutic aids are applied over common diapers. So there is known, e.g., a side splint for correcting hip dysplasia in a harness form with rains, which system is fastened against the child's body. In order to obtain a necessary lean out of the babies' thighs a semi-rigid longitudinal portion is used, continuous in the back part and divided in the front part into two side portions embracing the child's thighs and secured to the harness waist region. In another embodiment the semi-rigid portion is formed as having an increased front and back parts with reins and a central crotch part with side portions embracing the child's thighs and fixable in a position turned around the thighs with small strips. Wearing the therapeutic aids of this kind presents a very uncomfortable task for a child. As well as the replacing of soiled diapers is complicated by a necessary release and refastening of the therapeutic aid.
U.S. Pat. No. 4,393,865 discloses a diaper for small babies destined to prevent or treat abnormalities of one or both hips, for example, dysplasia or joints subluxation. The diaper contains semi-rigid padding means which are parts of the diaper material and intended for the baby's thighs orientation into a desired position with an inclination taking into consideration pelvis and side deflection. To fix the above mentioned semi-rigid orientation means on the baby's body the diaper includes flexible closures. The orientation semi-rigid means can be destined, e.g., for treating the inflammations of the small of the back and sacral nerves and they arc then positioned at the back body part, or they can be destined for inflammatory illnesses of a pubic bone and then oriented in this region with the front side located between the baby's thighs. The diaper can be supplemented or combined with common absorbent means such as triangle diapers, diaper panties or disposable diapers. For example, with the orientation means for treating the small of the back and sacral nerves inflammations the diaper can contain absorbent means incorporated into an absorbent padding arranged as a diaper part in the vicinity of the diaper centerline, or it can contain a separate absorbent body with retaining means by which it can be attached to the diaper substrate, e.g., by welding or to be glued to it. In this case the absorbent body is located above the transverse orientation member. But said diaper is apt to slippage or turning out from the position between the baby's thigh when used. The diaper is made of polyurethan which is not especially useful as an absorbent means for absorbing discharged body fluids and makes cleaning and drying of the diaper rather difficult. The diaper fastening means, horizontal ones, do not prevent the diaper to drop off the user's waist, so the semi-rigid or padding means are not correctly placed.
From U.S. Pat. No. 4,961,737 a therapeutic diaper is known containing the main longitudinal panel from an elastic material having an inner and outer layers between which an internal pocket is found. On the opposite longwise edges of the longitudinal panel, at the panel short side, there are flexible side arms with fastening means for corresponding fasteners on the longitudinal panel outer surface at its second shorter side, for releasable fastening of the diaper on the user's body. In the longitudinal panel inner pocket a combined padding and an absorbent body is located with dimensions providing for fastening and holding the diaper in a flexible, or a closely similar position, and for body liquids absorption. At the longitudinal panel lengthwise edges elastic strips can be arranged to seal the panel around the user's legs and the slip of the diaper. The diaper when used is located in a manner that the longitudinal panel runs back from the user's back waist region down to the crotch and again upwards to the waist region on the opposite part of the body, with inner layer against the user's skin, while the flexible side arms extend from the back waist region forward and diagonally down and here their fastening means are secured to the fasteners on the outer surface of the longitudinal panel. The absorbent pad is a combined body made of a common absorbent and padding material with good absorbency, easily laundered, washable and driable, and repeatedly used. Although such a diaper serves both to therapeutic and common purposes, maintaining it in an applicable clean and dry condition, however, is time consuming and it is not applicable separately to individual purposes.
SUMMARY OF THE INVENTION
The above mentioned drawbacks are solved with the absorbent diaper pants according to the invention.
The absorbent diaper panties have a front part, a back part with an elastic member in the waist hole region, and a crotch part with elastic hems in the diaper pants leg holes, wherein the front part and the back part are provided with fastening means, and on the diaper pants inner surface side a changeable absorbent pad is arranged. The diaper pants are further provided with a therapeutic orthopaedic pad characterised in that the orthopaedic pad is located in a rectangular housing arranged on the diaper pants facing side, while this housing is by its front and back transverse end ends, in a takeable apart manner, secured to the end edges of the front part and of the back part and the absorbent pad is inserted inside retaining means.
According to a favourable embodiment of the invention the orthopaedic pad is made of a firm elastic material and arranged changeably in the rectangular housing.
According to another favourable embodiment of the invention the rectangular housing has a longitudinal dimension corresponding to the diaper panties length and a transverse dimension corresponding to its front part width, being closed at its front transverse end edge, adjacent to the front part end edge, while the opposite back transverse end edge, adjacent to the back part end edge, is open, and the rectangular housing is on both transverse end edges provided with fastening means for its securing to the diaper pants.
According to a yet another favourable embodiment of the invention the fastening means of the rectangular housing are formed by buttons, secured
