Description

Ergonomic hygienic pad

The present invention relates to the field of personal care and ergonomics. In particular, the invention relates to an ergonomic hygienic pad that allows correct defecation.

Defecation is performed daily. Today, a large part of the population performs jobs outside their place of residence. Using of means of communication, especially long-distance business trips and tourism, in combination with the natural need of daily defecation force the necessity to use public toilets. Therefore, for the majority of people a very important problem of toilet hygiene arises. It should be noted that the contemporary medical knowledge mentions the problem of toilet hygiene and the related fears as one of the main reasons behind constipation caused by psychological background. The second characteristic and important feature of the invention is its ergonomics. Defecation is a daily routine of our body and is associated with great muscular effort and high pressure generated within our organs. This activity should be done in an ergonomic way.

From the utility model application DE202006006552 a set consisting of a toilet seat and a matching lid is known, which can be attached to any of the standard toilets. The lid is connected to the rear part of the seat by means of hinges. The elliptical seat with a central hole is higher at the rear, resulting in a slightly inclined upper surface, that is lower in the front part. The lower surface has a flat shape suitable for being placed on the top of the edge of a toilet bowl.

On the other hand, patent application CN 106388678 discloses an ergonomic toilet seat. An oblique slope resistant to urine spill is positioned in the center of the front part of the seat and can be used to prevent urine leaking as well as for urine drainage. Symmetrical grooves relieving the sciatic nerve are arranged on two sides of the seat, so that a buffer space is formed when the sciatic nerves in the lower parts of the thighs stretch in the seat area, and the pressure may be also alleviated by a relatively long relieving groove. The area supporting the sciatic tuberosity, which has a bilateral symmetrical design, is placed on the inside of the rear middle part of the seat, and the pressure on the sciatic nerves is significantly reduced when the sciatic tuberosity participates in supporting. The oblique slope which limits the pressure distribution is positioned at the center of the rear part of the seat and can be used to assist the stabilization of the sitting position and to increase comfort of the user. Many ergonomic designs are adopted, so that the pressure on the sciatic nerves of the user is reduced as much as possible; avoiding numbness of lower limbs, whereas male users can also avoid the awkwardness of urine spilling.

The description US4244063 discloses a toilet seat to induce bowel movements comprising an elongated buttock supporting member, having a general curvature to overlie a portion of the upper surface of a toilet bowl. In the solution the buttock supporting member has a buttock contacting upper surface comprising an inner portion of the upper surface and the outer portion of the upper surface, the inner portion is modeled concavely over a portion of the buttock contacting upper surface, and the outer portion is modeled convexly over a portion of the buttock contacting upper surface. The concave modeled portion defines a concave curvature defined by the most concave points of the buttock contacting surface, the concave curvature has a greater degree of curvature than the general curvature of the buttock supporting member.

Furthermore, the patent application JP2011156279 discloses a toilet seat for sitting, comprising a support for supporting the body of the user, and a front part of the surface inclined forward on the upper surface of the support and in a position allowing contact with the user’s buttocks when the user sits, and rotating the pelvis in the direction of forward movement of the upper part of the pelvis. In the front part of the inclined surface, the front side is lowered, and when the user is sitting on the front inclined part of the surface and the front inclined part of the surface and the buttocks of the user are in contact with one another, the inner part of the tissue of the buttocks slides down along the front inclined part of the surface by the component force parallel to the front inclined part of the surface by gravity acting on the user, and thus, the skin of the buttocks of the user is pulled back by the front inclined part of the surface, and consequently the pelvis is rotated. The toilet seat further comprises a part limiting spreading of legs.

At the same time, patent specification US6385783 discloses non-slip ergonomic pads which are arranged on opposite sides of the upper surface of a toilet seat in order to support gluteus maximus muscle of the user, helping to align the pelvis and spine when the user is sitting on a toilet seat. The pads are formed from durable, non-slip material which slightly deforms when sat upon and has a shape memory to return to its original shape when pressure, caused by the user sitting on a toilet seat, is removed. The pads may comprise a single layer or multiple layers of open-celled sponge rubber or other material. When the pads have multiple layers, these layers may exhibit a continuous gradient of values of indentation force deflection. The material should be of substantially uniform thickness to provide uniform pressure distribution and a firm support. The pads have non-slip characteristics but they are not sticky to the touch. The pads can have a cloth surface layer to provide a surface for printing, on which a print, advert or a pattern can be applied. The pads may be fixed to a toilet seat temporarily or permanently.

The solutions existing in the prior art did not allow a favorable seating of the user while performing micturition or defecation, resulting in physiological and/or anatomical disorders, chronic or acute ailments of the sacrum, especially its ending, which is constituted by the coccyx. Among many people there is a very common problem, especially when sitting, manifested by sacrum pain, due to a recent injury or there is also soreness due to a trauma in the childhood. Pathological changes in the sacrum are often permanent and irreversible, so that the pain caused by daily physiological activities is burdensome. In addition, the pressed soft tissues at the height of the ischial tuberosities may transform into bed sores, especially in the elderly. In addition, many people after reaching their sixties has a tendency for constipation. Consequently, their sitting time on a toilet seat is getting longer. It results in time, including the remaining time spent in a sitting position, in significant ischemia, and thus tissue hypoxia around the ischial tuberosities. As a result, there is great inconvenience when using a toilet. Moreover, there is the problem of the thigh section of the lower limbs, resulting from the pressure on the blood vessels and nerves, especially on the inner and back parts of the thighs.

Another problem during defecation is to provide tight contact of a toilet seat to the surface of a toilet to limit the spillage of defecation and micturition products outside the toilet seat.

Another problem to be solved is the acoustics of a toilet bowl and the associated psychological problems associated with defecation, often connected with the sounds resulting from this physiological activity.

With a view to ensure a better care for the health and comfort of the society, the inventors decided to develop an original solution with a unique shape having the function of the seating area which provides comfort resulting from pro-health approach based on an anatomical norm.

The best method of alleviating such problems is to relieve stress during repetitive physiological activities. To meet these expectations, the inventors decided to develop a novel pad with a suitable shape, which would eliminate the disadvantages of the prior art.

The ergonomic hygienic pad should help the user to obtain physiologically and anatomically correct position, so that it is ergonomic, and therefore healthy. In this way, one can prevent many health problems that arise around defecation. We have here in mind the widespread problems with constipation, which relate to a significant part of modern human population. The essence of the ergonomic hygienic pad is that it has elongated recesses, relieving the ischial tuberosities and the inner part of the thighs, arranged on the upper surface in the middle and rear parts, and in the rear part, the elongated recesses overlap the rear support. In this solution, the elongated recesses have different depths along the length and width of the pad, and extend on both sides of the hole, from the side edge of the hole towards the outer side edges over a part of the width of the pad. The surfaces of the elongated recesses are inclined towards the edge of the hole, wherein the elongated recesses are arranged from the front part of the hole to the rear part of the hole, and they follow curves with the maximum recess located at the point corresponding to the ischial tuberosities of the user of the pad. On the upper surface of the pad, at the side edges, in the rear part of the pad, between the arcuate outer peripheries of the elongated recesses and the rear support are positioning recesses fixing the buttocks, and which recesses have different depths along the length and the same depth along the width. The upper surfaces of the pad in the front part are flat and inclined with respect to the bottom surface at an angle ranging from more than 14^° to 50^°, and have extended side surfaces to support the thighs. The present solution has a rear wall of the outer surface of the rear support that is inclined at an angle with respect to the bottom surface of the pad, and the inner wall of the hole in the rear part of the pad is inclined at an angle towards the bottom surface of the pad. In this arrangement, the hole has a contraction in the middle of the length of the pad.

In a preferred embodiment, the elongated recesses are located from the 1/3 of the length from the front edge towards the rear edge of the pad and the elongated recesses are located at the 2/3 of the width of the pad, wherein the elongated recesses have a maximal depth ranging from 0.5 to 2 cm, preferably 1.4 cm. In a preferred embodiment, the positioning recesses are arranged symmetrically on both sides along the upper surface of the pad, wherein the positioning recesses 11 have a maximal depth from 1 cm to 5 cm, preferably 3 cm, and have a shape corresponding to the shape of human buttocks. Preferably, the height of the rear support of the ergonomic hygienic pad is at least twice the height between the maximum depth of the recesses and the base. The outer wall of the rear part of the pad and the inner wall of the rear part of the hole are parallel and the angle of the slope ranges from 1 to 40°, preferably 18°, creating the lower edge shift towards the rear, and the shift ranges from 0.26 cm to 12.59 cm, preferably 3 cm.

Preferably, the angle of the slope of the front upper surface with respect to the base is 21 °.

Preferably, the elongated recesses are lined with non-slip gel material and on the bottom surface, cushions are placed on, wherein the cushions are made of nonslip material and/or soundproofing material and/or material containing antibacterial substances. In a preferred embodiment, the pads are multi-layer disposable stickers with tabs, wherein the stickers are made of paper or other biodegradable materials, and wherein the stickers preferably contain silver ions or other substances with sanitizing and/or disinfecting effect.

In another preferred embodiment, the pad has a handle in the rear support, wherein the handle has the form of an oval elongated hole provided in the upper part of the rear support or the form of an oval elongated handle formed along the upper edge of the rear support.

In a preferred embodiment, along the edges of the outer side walls, the pad has holes for grasping and carrying. In another embodiment, from the base surface, along the periphery, it has storage compartments for hygienic and disinfecting agents.

Preferably, the ergonomic hygienic pad is secured to a toilet bowl, a toilet seat, a bidet or a potty by additional fasteners selected from the group consisting of hinges, asymmetric hinges, screws, washers and pins, that are provided in the rear part of the rear support. Preferably, the pad is a part of a toilet, a toilet seat, a bidet, a potty, or it is a portable toilet pad. Preferably, when in one embodiment, the ergonomic hygienic pad along the sides and the rear wall has a peripheral cavity. In another embodiment, the ergonomic hygienic pad in the rear part between the buttocks supporting surfaces has a cutout of the rear wall to relieve the sacrum, wherein the side surfaces of the cut-out are angled with respect to the base surface, and the cut-out has a width ranging from 1 to 15 cm, preferably 5 cm.

Human being as Homo erectus - an upright creature exists, according to the latest findings for 2,100,000 years. This means that the natural human posture is a straighten one. In such a situation, the length of the soft tissues and their tension, which determines the proper function, remain normal. Likewise, the anatomical relations of the skeletal system in the upright position remain normal.

Pannjabi and other authors came up with the concept of the "neutral zone" (a small range of motion near the zero position of the joint, where osteoligamentous resistance is minimum). An important issue from the point of view of human health is the preservation of the physiological curvatures of the spine, created by the correct positioning of the pelvis. McKenzie and others proved that the loss of the physiological spine curvatures results, mainly by impaired mechanics, in the destruction of the intervertebral discs. Modern science recognizes this mechanism as fundamental in the formation of pathologies of the human locomotor system, and especially in the formation of discopathy.

When defecating in a squatting position, a person loses the physiological curvature of the spine. Particularly in the lumbar region, increased pressure is then created within the nucleus pulposus of the intervertebral discs. After many repetitions (defecations) this leads to discopathy. The L4-L5 and L5-S1 disks are most exposed to damage during defecation in the squatting position. This is because squatting causes a lot of backward rotation of the pelvis. This mechanism arises as a result of exceeding the value of the physiological flexion angle of the femur in the hip joint, which standard is 120°. In the squatting position, the flexion angle of the hip joint is 145°. In addition, when squatting, a large abutment of the femoral head against the acetabulum is created, which is known to be the cause of coxartrosis. Therefore, the squatting position leads to pathological changes in the spine, especially the lumbar spine, and in the hip joints.

The defecation process is neurologically controlled by sympathetic and parasympathetic centers located in the lumbosacral segment. Moreover, for the proper course of defecation, tension of the muscles forming the abdominal press and the pelvic floor muscles is needed. The abdominal muscles play a major role in creating the abdominal press, the function of which is controlled by the centers located in the lumbar segment of the spine. Likewise, the puborectalis muscle, as a striated muscle, is controlled from the lumbar segment. Thus, disorders of its neurological control may for example cause paradoxical tensions. Considering the above, the squatting position, as the farthest departure from the physiological upright position, disturbs the function of the human locomotor system. The lumbosacral segment is especially exposed to dysfunctions while squatting, at the level of which there are located the centers controlling very important and complicated process of defecation. During 80 years of life, the average person performs about 30,000 defecations. So many times, and very strongly, the person tenses many muscles at the same time and creates an increased pressure within the internal organs. From the point of view of prophylaxis, it is important in what position we perform this hard, everyday work. If we maintain the physiological posture, this work can be called ergonomic.

In order to overcome the existing problems in the prior art, the inventors provide the ergonomic hygienic pad according to the invention, which allows to maintain the basic level of hygiene during micturition and defecation. It should be noted that many people sit on the toilet seat in public places, because of disability and/or senior age. During defecation and micturition, the personal pad will enable these users to maintain personal hygiene. The pad due to its original shape and height resulting from the specific construction, effectively separates the user’s body from the sanitary equipment such as a toilet or a bidet. The ergonomic hygienic pad also allows for a correct positioning of the pelvis which substantially determines the preservation of the physiological curvatures of the spine. In this way, we can keep the physiological norm of the work of the nerve centers that control defecation.

The solution provides a position on a toilet with the widest possible angle between the axis of the torso and the axis of the thigh. In the embodiment of the invention, the angle should range from 103° to 140°. It should be noted that this angle, in the squatting position, is 35°. In addition, the ergonomic hygienic pad is a personal portable equipment, which means that its owner can take the pad wherever he/she intends to go.

In order to provide a correct seating of the user, the ergonomic hygienic pad according to the invention is equipped with an assembly of asymmetrical recesses adapted to the pelvis structure, and the seating place is equipped with a non-slip gel cushion. Moreover, in order to provide the correct posture when the ergonomic hygienic pad is used, it is inclined forward at an angle of at least 14°.

Thanks to the solution according to the invention, firstly we relieve the ischial tuberosities and the lower part of the thighs section by the steady pressure on the tissues through the seating surface of the pad. This effect is achieved through the suitably shaped recess in the rear part with the simultaneous support of the femur, which at this point constitutes a lever arm relieving the user. Secondly, the proper profiling of said recesses in the inner part, directed with a slope towards the inside of the toilet seat,, relieves this part of the thigh, where the major blood vessels and lower limbs nerves run.

Example 1

This example illustrates the ergonomic hygienic pad, depicted in Figs. 1 , 2, 3, 4, 5, and 8. The pad according to one embodiment has an upper surface sloping towards the front of the pad, elongated recesses (1) located on the upper surface (2) of the pad, and a centrally located hole (5). The elongated recesses (1) are arranged on the upper surface (2) in the middle and rear parts of the pad, wherein in the rear part they overlap the rear support (3). Moreover, the elongated recesses (1) have different depths in length and width. In order to better reflect the change in the depth of the elongated recesses, Fig. 5 shows sections of the side surface of the pad in the characteristic areas marked in Fig. 4. The elongated recesses (1) are arranged opposite to each other with respect to the hole from the side edge (4) of the hole (5) towards the outer side edges (6) over a part of the width of the pad. The elongated recesses (1) are located from the 1/3 of the length from the front edge towards the rear edge of the pad and the elongated recesses (1) are located at the 2/3 of the width of the pad, wherein the elongated recesses (1) have a maximal depth of 1.4 cm. The surfaces of the elongated recesses (1) are inclined towards the edge (4) of the hole. In addition, the recesses (1) extend from the front part of the hole to the rear part of the hole, and they follow curves with the maximum recess located at the point corresponding to the ischial tuberosities of the user of the pad. In addition, positioning recesses (11), which have different depths along the length and the same depth across the width, are provided on the upper surface of the pad, at the side edges, in the rear part of the pad, between the outer arcuate peripheries of the elongated recesses (1) and the rear support (3). From the side view of the positioning recess (11), all the contour lines overlap and form one elliptical line sloping towards the base of the pad. This means that the lines perpendicular to these contour lines, extending across the surface of the recess, are formed by points located at the same distance from the line of the bottom surface of the toilet seat.

In this embodiment, the recesses have a maximal depth of 3 cm, and have a shape corresponding to the shape of human buttocks. The upper surfaces (2) of the pad in the front part are flat and inclined with respect to the bottom surface at an angle of 21°, and have extended surfaces (7) to support the thighs. In the present embodiment, the rear wall (8) of the outer surface of the rear support (3) is angled with respect to the bottom surface of the pad, and the height of the rear support (3) is twice the height between the maximum depth of the recesses and the base. The inner wall (9) of the hole (5) in the rear part of the pad is inclined at an angle towards the bottom surface of the pad. In the present embodiment, the hole (5) has a contraction (10) in the middle of the length of the pad. Furthermore, the outer wall (8) of the rear part of the pad and the inner wall of the rear part of the hole are parallel and the angle of the slope is 18°, creating the lower edge shift towards the rear, and the shift is 3 cm.

In a preferred embodiment, the elongated recesses (1) are lined with non-slip gel material. Furthermore, in a preferred embodiment, on the underside surface of the pad, cushions made of non-slip material may be placed on (not shown). In another preferred embodiment, the pads made of soundproofing material and material containing antibacterial substances may be placed on the underside surface of the pad. On the one hand, such pads seal the contact surface between the bottom surface of the pad and the surface of a toilet bowl and on the other hand, the pads significantly reduce the sound intensity improving the psychological comfort of the users.

The solution according to the invention in another embodiment may be attached to a toilet bowl, a toilet seat, a bidet or a potty by means of additional fasteners selected from the group consisting of hinges, asymmetric hinges, screws, washers and pins, that are provided in the rear part of the rear support. In one embodiment, the pad, along the outer edges (6) of the side wall, has holes (14) for grasping and carrying, and from the base surface, along the periphery, it has storage compartments for hygienic and disinfecting agents.

Example 2

In a further embodiment, the ergonomic hygienic pad is depicted in Fig. 6. In this embodiment, the pad has a peripheral cavity (12) along the sides and rear wall of the pad, thereby making it lighter and more handy for transport. In a preferred embodiment, the pad is a part of a toilet, a toilet seat, a bidet, a potty, or is a portable toilet pad. In another embodiment, the pad is not permanently attached to a toilet bowl, but placed on its surface before the defecation or micturition. In this embodiment, the pad does not have holes (14) for its carrying, since it can be accomplished using the edges of the pad made of the cavity on the side walls and rear wall.

Example 3

In a further embodiment, the ergonomic hygienic pad is depicted in Fig. 7. In this embodiment, the pad has, in its rear part between the buttocks supporting surfaces, a cut-out (13) of the rear wall to relieve the sacrum, and the side surfaces of the cut-out are angled with respect to the base surface. The above- mentioned cut-out is 5 cm wide.

Example 4

In a further embodiment, the ergonomic hygienic pad is depicted in Fig. 9. The pad in this form has a peripheral cavity (12) along the sides and rear wall of the pad. Moreover, the pad has, at the rear part between the buttocks supporting surfaces, a cut-out (13) of the rear wall to relieve the sacrum, and the side surfaces of the cut-out are angled with respect to the base surface. Example 5

Fig. 10 shows a further embodiment disclosing the ergonomic pad having the shape of the upper surface as described in the previous embodiments. The recesses on the upper surface of the pad force the correct posture of the person sitting on it. The depth of the elongated recesses is particularly important, and it is measured with respect to the depth of the positioning recess (11). The depth of the elongated recesses (1) is measured between edging contour lines, as shown in Fig. 3 and Fig. 4, i.e. between outer and inner contour lines of the elongated recesses. The depth of the elongated recesses (1) depends on the intended use of the pad, wherein pads for use by smaller individuals, e.g., students and adolescents, have smaller ranges, and pads for adult users with higher weight have larger ranges of the depth of the elongated recesses (1).

As shown in Fig. 3 and Fig. 4, using parallel contour lines, the positioning recesses (11) have the same depth over their entire width, and their depth is measured with respect to the upper surface of the pad at the place corresponding to the pelvis positioning.

According to an embodiment, the pad additionally has, in the rear support (3), a handle (15) to facilitate the carrying of the pad, wherein the handle has the form of an oval elongated hole in the upper part of the rear support (3). The size of the hole is adapted to the standard width of an adult user's hand, thanks to which the fingers can be easily inserted to grasp the pad. In this embodiment, the handle (15) extends over 1/4 of the width of the rear support.

Another type of handle for carrying the pad is shown in Fig. 11. In this embodiment, the handle (15) is an oval elongated handle formed in the rear support (3) along the upper edge. Example 6

A further preferred embodiment of the pad is shown in Figs. 12 and 13. In this embodiment, the pads are attached to the underside surface of the pad and they are multi-layer disposable stickers (16) with tabs (17). This additional element was used to increase the level of hygiene. The stickers are made of paper, and there are ten of them in this solution. Such individual layers are removed each time the pad is used. However, the number of the stickers may vary depending on user’s needs. In other embodiments, other materials that are readily biodegradable can be used in place of the paper sticker.

In one embodiment of the invention, the stickers contain silver ions, wherein in another embodiment, the stickers contain other substances with sanitizing and/or disinfecting effect.

Separation of another layer of the sticker is facilitated by tabs (17) located on the periphery of the sticker. The tabs have no adhesive material and are large enough to facilitate separation from one another allowing for easy grasping by the user. Moreover, the tabs are positioned so that they do not come into contact with the toilet seat.

Additionally, the pad in this embodiment has disposable gloves in the peripheral cavities (12) along the sides of the pad in order to increase the comfort of when the pad is used.

The authors of the present invention carried out additional scientific research confirming the usefulness of developing such a shaping of the solution that met the goal set by the inventors for the solution itself. The results of these studies were published in the "Physiotherapy Review", vol. XXIV, No. 3/2020.
