Description

Technical Field

[0001] This invention relates to disposable stacked bed packs. Background Technology

[0002] With the explosive growth of the caregiver population worldwide, especially in Asian countries including Japan, the incidence of serious illness among caregivers is also increasing. Therefore, to effectively address this increase in serious illness among caregivers, there is a need to further strengthen care and support services, and various countermeasures have been proposed. However, for those responsible for caring for caregivers—who play a central role in implementing these countermeasures—the measures remain inadequate, particularly the severe shortage of human resources. The workload at care and support facilities is increasing year by year, reaching a point where a chronic breakdown has begun, thus requiring the rapid development and implementation of improvement measures.

[0003] One of the most physically demanding tasks in care and nursing care is changing bed linens for critically ill patients and bedridden individuals. For example, in wards with a high number of critically ill or bedridden patients, it is essential to frequently address urinary or fecal incontinence and to prepare beds in advance to prevent pressure sores. However, these tasks, especially during night shifts, become extremely tedious and physically demanding. Therefore, the physical burden on those working in care and nursing care is significant, and it is common to hear of them experiencing physical and mental exhaustion.

[0004] Furthermore, in care and nursing settings, safe care and monitoring of critically ill and bedridden patients are required. The frequent handling and changing of bed linens, along with the bed-making process incorporating measures to prevent pressure ulcers, has become more complex and time-consuming, increasing the difficulty. In addition, the emergence of new infectious diseases necessitates meticulous infection control measures around hospital beds and their strict adherence. This further complicates and exacerbates the already heavy workload in care and nursing settings. Consequently, the physical burden on those working in these settings has become even heavier.

[0005] Therefore, some have proposed a multi-layered waterproof bedding pack that combines the functions of both an absorbent layer and a waterproof layer (see Patent Documents 1 and 2). Furthermore, some have proposed a multi-layered bedding pack that includes a waterproof layer, an inner layer with anti-slip properties, and an outer layer to prevent the bedding pack from shifting (see Patent Document 3). Others have proposed a disposable bedding pack that is configured as a long strip for easy replacement (see Patent Document 4).

[0006] [Existing technical documents]

[0007] [Patent Literature]

[0008] Patent Document 1: Japanese Utility Model Registration No. 3065526

[0009] Patent Document 2: Japanese Patent Application Publication No. 2022-029513

[0010] Patent Document 3: Japanese Patent Application Publication No. 2022-059346

[0011] Patent document 4: Japanese Patent Application Publication No. 2007-029535. Summary of the Invention

[0012] [The problem that the invention aims to solve]

[0013] The bed covers proposed in Patent Documents 1 and 2 are beneficial in preventing mattress contamination. However, from an infection prevention perspective, the contribution to reducing the workload of caregivers is not significant because a new bed cover needs to be quickly replaced each time urine or fecal leakage or contamination occurs. Furthermore, the cost reduction effect is also small. In addition, the large number of items required for bed cover replacement not only necessitates considerable time for preparation but also requires more time and manpower for the replacement itself. Therefore, the bed covers proposed in these patent documents are not suitable for caregivers requiring numerous tasks within a given timeframe.

[0014] The bed sheet proposed in Patent Document 3 has anti-slip properties on its inner layer, which can prevent the bed sheet from shifting. However, due to its special structure, the cost is relatively high. Furthermore, in terms of soiling, it is not a suitable bed sheet for caregivers who need to reduce care costs. The requirement to quickly replace the bed sheet each time it becomes soiled presents the same problem as the bed sheets proposed in Patent Documents 1 and 2.

[0015] Furthermore, while the bed sheet proposed in Patent Document 4 can be quickly replaced even if it becomes soiled, it requires specialized equipment and space for installation, thus lacking versatility. Moreover, regarding the need to replace the bed sheet each time it becomes soiled, it suffers from the same problem as the bed sheets proposed in Patent Documents 1 or 2. Additionally, this bed sheet cannot be replaced to address soiling on the sides of the bed, requiring further improvement.

[0016] Furthermore, the bed sheets described in Patent Documents 1, 2, and 4 are prone to wrinkling and becoming a source of pressure on the skin when the person being cared for repeatedly turns over or gets up in bed, thus easily leading to bedsores, which must be strictly avoided by the person being cared for. Therefore, from the perspective of bedsore countermeasures, this is also something that needs to be improved.

[0017] Therefore, the problem to be solved by the present invention is to provide a novel bed sheet that requires fewer preparation items for setting up and changing the bed sheet, has a short operation time for setting up and changing the bed sheet, and is low-cost and economical.

[0018] Furthermore, the problem that this invention seeks to solve is to provide a novel bed sheet that shortens the unnecessary work routes between the bed sheet setup and replacement equipment storage area, simplifies and standardizes the work steps, and makes it easy to plan standard work steps.

[0019] Furthermore, the problem that this invention aims to solve is to provide a novel bed sheet that, even with repeated turning over or getting up, bending of the mattress, or pressure-relief actions of the air mattress, is less likely to create wrinkles on the bed sheet that compress the skin and contribute to bedsores, thus achieving a bedsore prevention effect, and without hindering the original bedsore prevention effect of the bed, mattress, or air mattress for the caregiver using the bed sheet.

[0020] [Technical means used to solve the problem]

[0021] Therefore, the inventors, through repeated trial and error, have developed a novel disposable stackable bed sheet that contributes to the bed sheet replacement service or infectious disease countermeasures for critically ill and bedridden patients, as a technical means to solve the aforementioned problems.

[0022] The first embodiment of the present invention, intended to solve the aforementioned problems, is a disposable laminated bedding pack comprising: a first bedding pack integrally formed of a surface layer made of absorbent material and an inner layer made of waterproof material; and a second bedding pack comprising multiple sheets, each smaller than the first bedding pack material integrally formed of the surface layer made of absorbent material and the inner layer made of waterproof material, laminated on the surface layer of the first bedding pack. Each bedding pack is fixed to the other at its long and short sides along the outer periphery of the second bedding pack by a first fixing part. Each second bedding pack is fixed to the other at a position further inward of the long sides of the first fixing parts by a second fixing part that cuts across the long sides. A seam is provided at a position further inward of the short sides of the first fixing parts, cutting across the short sides. This seam has a seam width of 1.5 to 50 mm, and the seam width is adjusted to 0.5 to 50 mm, taking into account safety and stability in the usage environment, thus providing a disposable laminated bedding pack.

[0023] The second aspect of the present invention for solving the above-mentioned problems is a disposable laminated bed pack as described in the first aspect of the present invention, wherein the aforementioned first fixing part and / or second fixing part are sewn and / or attached.

[0024] The third embodiment of the present invention for solving the above-mentioned problems is a disposable laminated bed pack as described in the first embodiment of the present invention, wherein the inner layer of the aforementioned first bed pack and / or second bed pack is a breathable and waterproof material.

[0025] Another embodiment of the present invention for solving the above-mentioned problems is a disposable laminated bed package as described in the first embodiment of the present invention, wherein the aforementioned surface layer is composed of a nonwoven fabric layer selected from spunlace nonwoven fabric, needle-punch nonwoven fabric, spun-bound nonwoven fabric, meltblown nonwoven fabric, etc.

[0026] Another embodiment of the present invention for solving the above-mentioned problems is a disposable laminated bed package as described in the first embodiment of the present invention, wherein the aforementioned inner layer is selected from microporous polyolefin, polyurethane, polytetrafluoroethylene and other microporous membranes.

[0027] The fourth embodiment of the present invention for solving the above-mentioned problems is a disposable layered bed pack as described in the first embodiment of the present invention, which has: the end of the short side portion of the aforementioned first bed pack is bent inward, and a bag-shaped mattress insertion fixing portion is formed by the inner layers being fixed to each other by the third fixing portion at a position further inward than the long side portion of the first bed pack on the bent portion.

[0028] The fifth aspect of the present invention for solving the above-mentioned problems is a disposable laminated bed pack as described in the fourth aspect of the present invention, wherein the aforementioned fixing part is sewn, glued and / or welded.

[0029] The sixth embodiment of the present invention for solving the above-mentioned problem is a disposable laminated bed pack as described in the first embodiment of the present invention, which has: the end of the short side portion of the aforementioned first bed pack is bent toward the surface side, and a bag-shaped insertion fixing portion is formed on the bent portion at a position further inward than the long side portion of the first bed pack, where the surface layers are fixed to each other by a third fixing portion.

[0030] The seventh aspect of the present invention, which addresses the aforementioned issues, is a disposable laminated bed pack as described in the sixth aspect of the present invention, wherein the aforementioned fixing part is sewn and / or attached.

[0031] The eighth embodiment of the present invention, which solves the above-mentioned problem, is a disposable laminated bed pack as described in any one of the first to seventh embodiments of the present invention, wherein, as a result of pulling away or cutting away one or more pieces of the second bed pack that are more inside the second fixing portion from the upper layer, a wall is provided with the residual portion on the inner side of the long side portion, and one or more pieces of the second bed pack that have not been pulled away or cut away are provided in the lower layer.

[0032] [The effects of the invention]

[0033] The disposable stackable bed sheet of the present invention is positioned such that a second bed sheet, consisting of multiple sheets of material smaller than the first bed sheet stacked on the surface layer of the first bed sheet, is placed on the bed, and then the outer periphery of the first bed sheet protruding from the bed is rolled into the mattress and secured to the bed. When positioned on the bed, the location of the second bed sheet, particularly the first and second fixing portions located on the outer periphery of the second bed sheet, serves as a reference, thus achieving the excellent effect of quickly and easily placing the disposable stackable bed sheet of the present invention.

[0034] In addition, in a typical bed sheet, when the head of the bed is raised, the patient's body may slide down along with the bed sheet, which may cause the patient to shift their position.

[0035] On the other hand, the disposable stackable bed sheet of the present invention includes a bag-shaped insertion and fixing part, through which the bed sheet is fixed to the head of the mattress. Therefore, when performing treatment, care, and nursing procedures with the head of the bed raised, the bed sheet is suspended and held in the desired position by the bag-shaped insertion and fixing part, resulting in the excellent effect of maintaining the patient's posture in a good state.

[0036] Moreover, the fixing operation itself is simply inserting the head side of the mattress into the bag-shaped insertion fixing part of the disposable stacked bed pack of the present invention, or after placing the disposable stacked bed pack of the present invention on the bed, flipping the bag-shaped insertion fixing part and inserting it in a way that covers the head side of the mattress. In addition, the outer periphery of the first bed pack is rolled into the mattress and fixed on the bed, thus making it an extremely simple process.

[0037] Furthermore, in the disposable stacked bedding of the present invention, colored sewing thread or adhesive can be used to construct the first fixing part and / or the second fixing part. Since the use of colored thread makes it easier to control the position, it is easier to correct the slant of the disposable stacked bedding during installation. In addition, since it functions as a clear guide for controlling the position of the edge portion of the cut-off part of the second bedding, the accuracy of bedding replacement operations is improved.

[0038] In conventional bed packs that employ special securing methods that require confirmation of specific operational procedures before implementation, it is difficult to incorporate bed pack replacement procedures, such as special instructions related to the bed pack securing method, into standard operational procedures related to treatment, care, and nursing care during the handover process between physicians, nurses, and caregivers.

[0039] On the other hand, in the disposable stacked bed roll of the present invention, the first bed roll is sufficiently larger than the second bed roll, and by increasing the area of ​​the bed roll rolled into the mattress, an excellent effect is achieved in strengthening the fixation of the bed roll to the bed. Furthermore, when the bed roll needs to be urgently removed from the mattress for emergency treatment, only the portion of the first bed roll rolled into the mattress needs to be pulled out. Even for first-time users, this is easy to perform and will not interfere with normal treatment, care, and nursing activities.

[0040] Unlike the present invention, in a bed pack where each bed pack is simply stacked and secured to the other along the long and short sides of the outer periphery of the second bed pack only by a first fixing part, the outer periphery of the second bed pack remains when it is pulled away. However, since this remaining portion is held only by the first fixing part, it is easy to pull it away with a little force, resulting in bed pack fragments that become rope-like, or wheel-like objects formed by partially pulled-away rope-like bed pack fragments. As a result, a patient lying on the bed pack may unconsciously use these rope-like bed pack fragments or wheel-like objects to injure themselves, posing a risk of accidental injury. Using bed packs with this structure can cause significant problems in treatment, care, and nursing settings where safety is paramount.

[0041] On the other hand, in the disposable stacked bed pack of the present invention, the second bed pack is fixed to each other by a second fixing part that cuts across the long side portion at a position further inside the long side portion of each of the first fixing parts. Furthermore, the stacked bed packs are fixed to each other by the first fixing part at positions along the long and short sides of the outer periphery of the second bed pack. Therefore, even when changing the bed pack by pulling away the second bed pack which is further inside the second fixing part, the outer periphery of the remaining second bed pack after pulling it away remains fixed by the double fixing parts. Therefore, even if a patient lying on the bed pack or a person performing treatment, care, or nursing comes into contact with the outer periphery of the second bed pack fixed only by the first fixing part, the remaining portion will not peel off, thus preventing the formation of thread-like bed pack fragments or thread-like bed pack fragments in wheel shape. Thus, the disposable stacked bedding of the present invention does not produce bedding fragments or wheel-shaped objects that become rope-like fragments, thus achieving an excellent effect of eliminating concerns about self-injury or accidental injury.

[0042] In addition, when changing the second bed sheet by pulling it further inward than the second fixing part, a long wall that blocks liquid can be formed, especially through the bed sheet residue on the two long sides of the cut surface. With this wall, even if the patient experiences incontinence and expels a large amount of urine that cannot be completely absorbed by the bed sheet exposed after being pulled away, it can be blocked further inward than the wall, preventing the incompletely absorbed urine from leaking out of the bed sheet and keeping it inside the wall. Even with long-term use, the higher the wall formed by the bed sheet residue becomes with each repeated pulling of the second bed sheet further inward than the second fixing part, the more effective it is at preventing leakage. When used in cases where there is concern about leakage or incontinence in patients, the disposable laminated bed pack of the present invention can be pre-pulled away from the second bed pack, which is further inside the second fixing part, and provided as a disposable laminated bed pack with a wall formed. In this way, it can be configured as a disposable laminated bed pack that can more effectively absorb liquid components and easily maintain a hygienic environment from the start of use.

[0043] Furthermore, when the bed is raised, the multiple layers of bed sheets that are not sewn on the short side slide against each other, causing the bed sheets to deviate. As a result, the patient's posture or body shape changes significantly, and the patient's buttocks slide and deviate. Therefore, the patient's posture or body shape, which should be stable, can easily become unstable.

[0044] On the other hand, the disposable stackable bed pack of the present invention uses saddle stitching to fix the short side of the inner perimeter, preventing deviation when the bed is raised and the pack is stacked into multiple layers, so the patient's buttocks will not slip. Even when the patient is eating or taking medication, the patient's posture is kept stable, so the esophagus is not compressed and swallowing difficulties are not caused, thus ensuring safety.

[0045] Furthermore, the disposable layered bed sheet of the present invention has a longitudinal seam across the short side portion, located further inside the short side portion of the first fixing part. The person performing the treatment or care applies force by expanding both sides of the seam with their hand, thereby creating a structure where the top layer of the bed sheet can be easily pulled off one piece at a time from the seam, making bed sheet replacement extremely convenient. In particular, the inner layer, made of waterproof material, uses a material with strength that allows it to tear in one direction but not in a direction perpendicular to it, so as not to be accidentally torn by the patient's body pressure. The bed sheet material is then arranged such that the tear direction is the long side portion and the less tearable direction is the short side portion, and the seam is positioned in the less tearable direction, thereby facilitating the pulling operation. Only the contaminated surface can then be pulled off and removed, and the surface layer of the bed sheet, made of absorbent material, can be replaced with a clean one. Furthermore, compared to conventional bed sheets, the time required for setting up and replacing the bed sheet is shortened. Therefore, it becomes low-cost and highly economical.

[0046] In addition, the disposable folded bed sheet of the present invention reduces the risk of accidental contact by the patient or caregiver by placing the seam across the upper or lower end of the bed. Furthermore, even if a patient sleeping on their back in bed touches the seam, it is difficult to properly grasp the seam or its surroundings and apply force, thus achieving the excellent effect of eliminating the concern that the folded bed sheet may be accidentally peeled off.

[0047] As with traditional mattresses, if there are large slits or gaps in the mattress, such as those with a width greater than a fingertip (in centimeters), or if the mattresses have unsecured openings, a patient lying in bed may put their fingers or hands into these slits or openings, posing a risk of self-injury or accidental injury. Furthermore, there is the problem that instruments, pens, or even trash used during treatment, care, and nursing procedures can easily enter through these slits or openings. This not only creates hygiene problems but also poses a high risk.

[0048] On the other hand, the disposable laminated bed sheet of the present invention features a saddle stitch, allowing the length of the seam (i.e., the width of the hole) to be less than the roughness of a finger. This eliminates the risk of a patient lying in bed inserting their fingers into the hole formed by the saddle stitch in the disposable laminated bed sheet of the present invention, or of instruments, pens, or trash used during treatment, care, and nursing procedures entering the hole, providing a safer bed sheet without hygiene issues.

[0049] Furthermore, the length of the seam along the saddle stitch in the disposable laminated bed roll of the present invention can be set to be slightly longer than the roughness of a finger. In this way, within the permissible range of safety and stability in the usage environment, a disposable laminated bed roll that is easier to pull away from the second bed roll which is further inward than the second fixing part can be provided.

[0050] Then, when changing the disposable stacked bed sheet of the present invention, the following steps are taken: First, after shifting the patient's position to a semi-recumbent position, the uppermost second bed sheet, which is to be replaced, is pulled away halfway and rolled up. Next, the semi-recumbent patient's position is reversed to change the posture, and then the remaining portion is pulled away while rolling up for replacement. As a result, the disposable stacked bed sheet of the present invention can be changed even when the patient is kept in a nearly lying position, and the inner layer, made of waterproof material, is rolled up with the outer layer facing outwards, preventing contamination during the replacement process. Furthermore, because the bed sheet material is soft and thin, even when a semi-recumbent patient changes position, it is easy to pass over the rolled-up bed sheet, making patient position control easier and greatly reducing the burden on the treatment, care, and nursing staff.

[0051] In treatment, care, and nursing settings, when using traditional mattress covers to encase mattresses or air mattresses, waterproof rubber sheets are often sandwiched between the mattress cover and the mattress or air mattress to prevent soiling. However, rubber sheets are harder than mattress covers, and this rubber sandwich weakens the pressure-distributing effect of the mattress or air mattress, often causing pressure sores on the patient's skin.

[0052] On the other hand, the disposable layered mattress of the present invention, through the first fixing part and the second fixing part, securely fixes the multiple layers of mattress to the bed without deviation. Furthermore, since it is only made of mattress material, it provides a thinner and softer mattress. While noise from mattresses can be uncomfortable, the disposable layered mattress of the present invention produces very little noise, maintaining a quiet environment even at night. Moreover, since the disposable layered mattress of the present invention uses a waterproof material, there is no need for a waterproof rubber sheet between the mattress and the mattress or air mattress. Therefore, even if the person being cared for repeatedly turns over or gets up, or if the mattress is bent or the air mattress is pressurized, wrinkles that could cause pressure sores are less likely to form on the mattress, allowing the mattress or air mattress to fully exert its pressure-dispersing effect and achieving excellent pressure sore prevention while maintaining quiet operation.

[0053] In addition, if a bed sheet is made of a non-woven fabric layer as an absorbent material and a microporous membrane as a breathable and waterproof material, moisture is released to the outside of the disposable laminated bed sheet in a moderate manner, making it less stuffy. This can more effectively prevent bedsores or discomfort caused by stuffiness.

[0054] In addition, by using a flexible material consisting of a non-woven fabric outer layer and a microporous membrane inner layer, the bed sheet achieves excellent anti-bedsore effects without hindering the movement of the caregiver using the bed, mattress, or air mattress. Furthermore, the inner layer, composed of a microporous membrane that is breathable and waterproof, not only prevents contamination from transferring to the lower layers of the bed sheet but also prevents moisture from trapping.

[0055] Furthermore, in the disposable laminated bed sheet of the present invention, no sewing or other fixing parts are provided at a position further inside the long side portion of the first fixing part and further inside the second fixing part of the cross-section long side portion, so there are no components that absorb urine or feces and allow foul odors to penetrate, thus easily maintaining hygiene.

[0056] Furthermore, by shortening unnecessary travel routes between the equipment storage area and the relevant bed pack setup and replacement facilities, the operational procedures become simpler and more standardized. In addition, by using the disposable stackable bed pack of this invention, the caregiver's supervision and the standard operating procedures within the disposable stackable bed pack during care become easier to plan.

[0064] The following is a description of the embodiments for implementing the present invention with reference to the drawings.

[0065] <Materials for Disposable Stackable Bed Sheets>

[0066] First, the materials in the disposable laminated bed pack of the present invention will be described. The bed pack in the disposable laminated bed pack is composed of an absorbent material constituting the surface layer and a breathable and waterproof material constituting the inner layer.

[0067] The absorbent material constituting the surface layer is composed of a nonwoven fabric layer. This nonwoven fabric layer is selected from materials such as water-jet nonwoven fabric, needle-punched nonwoven fabric, spunbond nonwoven fabric, and meltblown nonwoven fabric. Water-jet nonwoven fabric is preferred.

[0068] The inner layer, made of a breathable and waterproof material, can be a porous sheet such as polypropylene, polyurethane, or polytetrafluoroethylene. Microporous polyolefin sheets are preferred, and microporous polypropylene membranes are even more preferred. The thickness is 5 to 1000 micrometers, and more preferably 30 to 500 micrometers.

[0069] The disposable stackable bed sheet of the present invention is made of the above-mentioned absorbent material constituting the surface layer and the breathable and waterproof material constituting the inner layer, and the thickness is about 55 gsm (Grams per square meter). Accordingly, the stacked bed sheet will not deviate and will be firmly fixed to the bed even during use, and will not hinder the caregiver's movement of using the bed, mattress, or air mattress, and will not affect the original anti-bedsore effect of these.

[0070] The inner waterproofing material is preferably a material that is tearable in one direction but not in a direction perpendicular to it, so as not to be accidentally torn by the patient's body pressure. Furthermore, the bed sheet material is arranged such that the tear direction is the long side and the less tearable direction is the short side, and the sutures are positioned in the less tearable direction, thereby facilitating the removal of the second bed sheet. When using a material other than microporous polypropylene membrane as the inner waterproofing material, the force required to tear the bed sheet at the sutures is the same as when using microporous polypropylene membrane, allowing for appropriate adjustment of the length of the seam portion constituting the sutures and the width between each seam without exceeding the level of finger roughness.

[0071] Example 1

[0072] The bed pack material used in the disposable laminated bed pack of the present invention is selected as follows: a bed pack having an outer layer made of a water-absorbing material as a water-jet nonwoven fabric and an inner layer made of a breathable and waterproof material composed of a microporous polypropylene membrane, with a thickness of 55 gsm (Grams per Square Meter).

[0073] The aforementioned bed pack, consisting of an absorbent outer layer made of a water-jet nonwoven fabric and an inner layer made of a breathable and waterproof material composed of a microporous polypropylene membrane, is arranged such that the long side of the bed pack is torn in the direction of tearing, and the short side is not torn in the direction of tearing. The bed pack is then cut into rectangles with a long side of 250cm and a short side of 175cm to form the first bed pack, and into rectangles with a long side of 190cm and a short side of 87.5cm to form the second bed pack. Multiple pieces of the first and second bed packs are cut out.

[0074] Next, two second bedding sheets are overlapped, and the stacked second bedding sheets are placed on the surface layer of the first bedding sheet. The long side of the first fixing part, which is sewn 5 mm inward from the outer perimeter, is positioned 5 mm inward. Each bedding sheet is then sewn with a transverse cut along the long side to secure it, thus forming the second fixing part and securing each second bedding sheet. Furthermore, the secured second bedding sheets are placed in the center of the first bedding sheet, and a first fixing part is formed by sewing along the long and short sides of the outer perimeter of the second bedding sheet, 5 mm inward from the outer perimeter, to secure each bedding sheet. Then, a 3 mm long seam with a 1.5 mm wide seam is formed with a longitudinal cut along the short side, 5 mm inward from the short side of the first fixing part. This is how a disposable stacked bedding sheet of the present invention is manufactured (Example 1) (see...). Figure 1 , Figure 2 ).

[0075] Furthermore, the disposable stacked bedding unit used in this embodiment is manufactured using the following method. First, two second bedding units are overlapped on the surface layer of the first bedding unit, and sewed along the long and short sides of the outer perimeter of the second bedding units at a distance of 5 mm from the outer perimeter to secure each bedding unit, thus forming a first fixing part. Next, at a position 5 mm inside the long side of the first fixing part (sewed at a distance of 5 mm from the outer perimeter), sewed transversely along the long side to secure each bedding unit, thus forming a second fixing part. Then, at a position 5 mm inside the short side of the first fixing part (sewed transversely along the long side), a 3 mm long seam with a 1.5 mm wide seam is formed by longitudinally cutting the short side (see reference). Figure 1 , Figure 7Disposable stacked bed packs of the present invention are thus manufactured.

[0076] The disposable stacked bed sheets manufactured by the above method are placed on the mattress with the second bed sheet positioned on top of the mattress. Then, the portion of the first bed sheet, which is further outward than the portion with the second bed sheet, is rolled into the mattress and secured.

[0077] A person with a height of 170cm and a weight of 60kg was placed on the disposable stackable mattress of the embodiment and repeatedly rolled over. It was confirmed that the disposable stackable mattress of Embodiment 1, by fixing the first fixing part on the outer periphery of the second mattress, keeps the second mattress firmly in place and prevents it from wrinkling. Furthermore, it was confirmed that it does not wrinkle easily even when the person is getting up or lying down. In addition, it was confirmed that it does not wrinkle easily even when the mattress is bent or the air mattress is compressed or decompressed.

[0078] When the topmost layer of the disposable stacked bed sheet in this embodiment is pulled away from the seam and the second fixing part, the top layer of the bed sheet to be replaced can be easily pulled away without putting excessive strain on the person in bed. This exposes the absorbent material surface layer of the second layer of the bed sheet, which remains clean, and it becomes the new surface layer of the disposable stacked bed sheet. The operation time required to discard the contaminated area and replace it with a clean one is extremely short.

[0079] Furthermore, when changing the bedsheet by pulling it away from the second bedsheet, which is further inward than the second fixing part, the wall formed by the vertical wall of the residual portion on both long sides creates a liquid-blocking wall. Here, assuming the patient experiences incontinence and vomits a large amount of urine that cannot be completely absorbed by the bedsheet exposed after being pulled away, and a large amount of liquid spills onto the bedsheet, this liquid will not leak out of the bedsheet but will be effectively retained inside the wall. Moreover, since the number of vertical walls formed by the residual portion of the bedsheet increases with repeated pulling of the second bedsheet further inward than the second fixing part, it is evident that it has the advantage of even greater leakage prevention effectiveness. When used in situations where there are concerns about leakage or incontinence, the disposable laminated bed pack of the present invention can be pre-pulled away from the second bed pack, which is further inside the second fixing part, and provided as a disposable laminated bed pack with a wall formed. Thus, it can be understood that from the beginning of use, it can be configured as a disposable laminated bed pack that can more effectively absorb liquid components and easily maintain a hygienic environment.

[0080] Furthermore, even with prolonged use, pens, tweezers, scissors, cotton, or other trash will not seep into the disposable stacked bed bag through the seams, thus maintaining cleanliness.

[0081] Next, each of the second bed packs is located further inside the long side portion of the first fixing portion, and is not fixed to each other by the second fixing portion that cuts across the long side portion. Otherwise, the disposable stacked bed packs of Comparative Example 1 are manufactured by the same steps as in Example 1.

[0082] Comparative Example 1 shows that when the second bed sheet was pulled away, a residual outer portion remained, especially near the seam. This residual portion easily detached from the sewn-in fixing and could be pulled away easily, forming a string-like or partially pulled-away thread-like fragment of the bed sheet. Patients lying on the bed sheet could easily come into contact with this string or thread-like fragment, potentially causing self-injury or accidental injury due to unconscious use of this thread-like fragment. Using a bed sheet with this structure is undesirable and can lead to significant problems in treatment, care, and nursing settings where safety is paramount.

[0083] In addition, except for the point where the first fixing part is not provided at the position along the short side of the outer periphery of the second bed pack, the other steps are the same as those in Embodiment 1 to manufacture the disposable stacked bed pack of Comparative Example 2.

[0084] A person 170cm tall and weighing 60kg was placed on the disposable stacked mattress of Comparative Example 2 and repeatedly turned over. It was confirmed that the short side of the outer periphery of the second mattress (without the first fixing part) warped, causing wrinkles on the area where the person was lying and in the surrounding area. Furthermore, it was confirmed that wrinkling occurred even with the person's sitting and lying movements. Additionally, it was confirmed that wrinkling occurred when the mattress was repeatedly bent or when the air mattress was compressed or decompressed. Moreover, during use, pens, tweezers, scissors, cotton, or other trash could easily enter the disposable stacked mattress, making it impossible to maintain cleanliness. Using a mattress with this structure is not ideal and could cause significant problems in treatment, care, and nursing settings where safety and cleanliness are paramount.

[0085] Example 2

[0086] The bed pack material used in the disposable laminated bed pack of the present invention is selected as follows: a bed pack having an outer layer made of an absorbent material as a water-jet nonwoven fabric and an inner layer made of a breathable and waterproof material composed of a microporous polypropylene membrane, with a thickness of 55 gsm (Grams per Square Meter).

[0087] The aforementioned bed pack, consisting of an absorbent outer layer made of a water-jet nonwoven fabric and an inner layer made of a breathable and waterproof material composed of a microporous polypropylene membrane, is arranged such that the long side of the bed pack is torn in the direction of tearing, and the short side is not torn in the direction of tearing. The bed pack is then cut into rectangles with a long side of 290cm and a short side of 175cm to form the first bed pack, and into rectangles with a long side of 190cm and a short side of 87.5cm to form the second bed pack. Multiple pieces of the first and second bed packs are cut out.

[0088] Next, a disposable stackable bedding unit of the present invention is manufactured as Example 2. A second fixing part is formed by sewing the long side portion of the first fixing part, which is sewn 5 mm inside the perimeter, with the long side portion cut across it. This forms a second fixing part. At a position 40 cm apart on one of the short sides, the first bedding unit is bent so that its inner sides are in contact with each other. Two second bedding units are then overlapped, 15 cm apart from the bent portion and centered between the long sides of the first bedding unit. After extending the bent portion of the first bedding unit, a 5 mm inside the perimeter portion of both the long and short sides of the second bedding unit is sewn to fix each bedding unit, forming the first fixing part. Further, at a position 5 mm inside the short side portion of the first fixing part, a 3 mm long seam with a 1.5 mm wide seam is formed by cutting the short side portion longitudinally. Then, the first quilt is bent so that the inside sides are in contact with each other, and a third fixing part is formed by sewing it at a distance of approximately 28.75 cm from the long side of the bend, thus creating a pocket-shaped insertion fixing part (see reference). Figure 3 , Figure 4 ).

[0089] In Example 3, two second bed sheets are overlapped on the surface layer of the first bed sheet, with the second bed sheet located approximately 8 cm away from the aforementioned bending portion and at the center between the long sides of the first bed sheet. Otherwise, the disposable stacked bed sheet of the present invention is manufactured through the same process as in Example 2.

[0090] Example 4, except for the point where the first bed sheet is bent so that its surface sides are in contact at a position 40 cm apart from one of the shorter sides, is manufactured using the same process as in Example 2 to produce the disposable stacked bed sheet of the present invention (see Example 2). Figure 5 , Figure 6 ).

[0091] In Example 5, the first bed pack is bent so that its surface sides are in contact with each other at a position 40 cm away from one of the short sides. Two second bed packs are then stacked on the surface layer of the first bed pack at a position approximately 8 cm away from the bent portion and located at the center between the long sides of the first bed pack. Except for this point, the disposable stacked bed pack of the present invention is manufactured by the same process as in Example 2.

[0092] The disposable stacked bed packs described in Examples 2 to 5 above can be easily fixed by inserting the head side portion of the mattress into the bag-shaped insertion fixing part, or by flipping the bag-shaped insertion fixing part after placing it on the bed and configuring it to cover the head side portion of the mattress, and then inserting it by rolling the outer periphery of the first bed pack protruding from the bed into the mattress.

[0093] A person with a height of 170cm and a weight of 60kg was placed on the disposable stackable mattress of Example 1 and repeatedly rolled over. It has been confirmed that the disposable stackable mattress of each embodiment, through the first fixing part securing the outer periphery of the second mattress, keeps the entire second mattress firmly in place and prevents wrinkling. Furthermore, it has been confirmed that wrinkling is minimal even during getting up and lying down. Additionally, it has been confirmed that wrinkling is minimal even during bending of the mattress or pressure-reducing movements of the air mattress.

[0094] When the topmost layer of the disposable stacked bedding in each embodiment is pulled away from the seam and the second fixing part, the top layer of the bedding, which is to be replaced, can be easily pulled away without putting excessive strain on the person in bed. This exposes the absorbent material surface layer of the second layer of the bedding, which remains clean, and it becomes the new surface layer of the disposable stacked bedding. The time required to discard the contaminated area and replace it with a clean one is extremely short.

[0095] Furthermore, even with prolonged use, pens, tweezers, scissors, cotton, or other trash will not seep into the disposable stacked bed bag through the seams, thus maintaining cleanliness.

[0096] Example 3

[0097] Except for setting the seam length to be 30mm and the seam width to be 5mm, the disposable laminated bed pack of the present invention (Example 6) is manufactured by the same steps as in Example 1.

[0098] When the topmost layer of the disposable laminated bed sheet in Example 6 is pulled away from the seam and the second fixing part, the fingers of the person performing the bed sheet replacement can easily get caught in the seam. Compared to Example 1, where the seam length is 3mm, it is easier to pull away the top layer of the bed sheet to be replaced without putting excessive strain on the person on the bed. This exposes the absorbent material surface layer of the second layer of the bed sheet, which remains clean, and it becomes the new surface layer of the disposable laminated bed sheet. The operation time required to discard the contaminated area and replace it with a clean part is reduced.

[0099] Furthermore, even when a person 170cm tall and weighing 60kg lies on the disposable folded mattress of Example 6 and repeatedly rolls over, it has been confirmed that the second mattress is firmly held in place and does not easily wrinkle due to the first fixing part securing the outer periphery of the second mattress. Furthermore, it has been confirmed that wrinkling is also minimal even during getting up and lying down. Additionally, there is no slippage or deviation of the buttocks. Furthermore, it has been confirmed that wrinkling is also minimal even during bending of the mattress or pressure-reducing actions of the air mattress.

[0100] By setting the length of the seam across the suture and the width between the seams to be longer, it is known that a benchmark for safety and stability in the usage environment can be provided, making it easier to pull away the surface of the bed pack that is to be replaced. Furthermore, the bed packs stacked in multiple layers do not deviate, and the patient's posture is stably maintained, thus ensuring safe disposable stacked bed packs.
