Description

【0001】
【発明の属する技術分野】
本発明は、就寝中の人体から発する汗、臭い、垢などの他、介護時に飛沫汚染する涎、人尿、人糞等の臭いを吸収し、かつ適度に柔らかく、医療および介護利用者の褥瘡(床擦れ)を軽減することができる寝装具に関する。
【0002】
【従来の技術】
寝装具は、人間が睡眠あるいは休養又は治療を受ける為に不可欠な道具であり、健康、不健康、年令を問わず毎日利用する。この為、長時間使用が余儀無くされ、人間から発する代謝産物、例えば汗、垢などで次第に汚染されている。
特に、治療を必要とする病人や介護を受ける人にとっては、涎、尿、便などで汚染される他、食事の場にもなる為に食事の取りこぼしで等で、汚染を受ける事もある。しかしながら、長い人類の歴史の中では就寝と同じ装具が、医療および介護などにも転用されて来ており、現代においても事情は変わらない。これは医療および介護では就寝時間が圧倒的に長く、仰臥位を取る時間が生活時間の中でほとんどを占める為であった。
【0003】
長時間同じ寝装具を用いていると、病人、老人など介護を受ける者にとっては、褥瘡(床擦れ)が大きな問題となってきた。この床擦れは一定の姿勢が長く続く為に、衣類・寝具によって圧迫を受け、その圧迫を受けた身体の部位に皮膚および皮下組織の壊死が起こった状態である。
発生の要因には、身体の自重による圧迫、摩擦、皮膚の湿潤や乾燥、浮腫、栄養不良、貧血、知覚麻痺、運動麻痺、意識障害および失禁等がある。
予防には、圧迫の原因を除く事であるが、除圧用品として、ウォーターマット、エアマット、ビーズマット、円座などがあり、これらは、褥瘡の出来易い後頭部、肩甲骨、仙骨部、踵部(かかと)、大転子部(太ももの内側)、外踝部(くるぶし)など骨の突出部に補助具を当て、圧力を分散させるものである。
しかしながら、圧力を軽減させながら、消臭や調湿ができるような素材は存在していない。上記例に示すように、多くはそれらの要求される性質は相反するものである。
【0004】
従来、寝装具のうち布団の材料としては、普及品として、木綿、高級品に真綿(絹綿)、羊毛、羽根(ダウン)が用いられて来た。近代では、高級品の材質はあまり変わらないが、普及品には、より軽量で安価な化繊やウレタン、化繊と木綿の混合品、あるいは輸入の安価な水鳥の羽などが用いられている。
布団材としての木綿は、吸湿性は高いが、使用中に水分を吸収し次第に重量が大きくなり、またかびやダニなどの発生があるので、日光消毒や定期的な布団乾燥が、清潔な環境を維持するには不可欠であった。
一方、枕の素材では、数十年前までは蕎麦殻が用いられて来たが、西洋式な生活習慣が導入され、薄くて大きな形状が一般的になり、部材には羽根、ウレタン、化繊、プラスチックなどが用いられている。
【0005】
上記のような布団やまくらの材料として、衛生面を考慮した抗菌物質などを塗布したものはあるが、吸収した汗、垢などの臭いを消臭する作用は少なく、特に医療、介護利用者の使用する寝装具には患者の臭いが移り、使用に伴って特有の臭いを発しているのが通常の状態である。
また、多くの製品は廃棄処理が難しいものがあり、特に衛生面や消臭効果、抗菌効果など、性能を高める工夫のあるもの程、その傾向が著しく、社会問題にすらなっている。
【0006】
【発明が解決しようとする課題】
本発明の目的は、吸湿性が高く、消臭作用がある上に、抗菌性を合わせ持ち、軽く、身体圧力を和らげる素材であり、さらに環境にも優しい寝装具及び寝装具用材料の製造方法を提供することを目的とする。
ここで寝装具とは、布団、枕、シーツ、毛布、肌掛け等の寝具、丹前、寝巻き等の装具を意味し、医療介護用に使用するもの及び一般家庭で使用する寝具及び装具を意味し、これらを包含する。
【0007】
【課題を解決するための手段】
本発明者は、上記目的を達成すべく鋭意研究を重ねた結果、木綿を焼成した炭素繊維材を使用することにより、上記の問題を解決できるとの知見を得た。
本発明は、この知見に基づいて、
1.炭化綿となる木綿生地をタオルとタオルの間に挟み込み、これを窒素雰囲気下200〜500℃で加熱焼成した炭化セルロースの二重構造を備える炭化綿を、炭化綿に付随する微粉末が拡散しないように、目の細かい布あるいは不織布で被って、使用することを特徴とする布団、枕、シーツ、毛布、肌掛け、丹前等の寝装具、を提供するものである。
【0008】
本発明者は、先に「炭化綿およびその製造法」(特願2001−020138)を提案した(先の発明)。本発明の医療介護用及び一般寝装具に使用する木綿を焼成した炭化綿は、この先願の発明の、炭化綿の吸着力に着眼して医療介護用及び一般寝装具へ利用するものである。
医療介護用及び一般寝装具への適用に際しては、木綿を焼成して得た炭化綿が有効であり、特に平均直径5〜15μmの長繊維の集合体からなる炭化綿、平均長さ0.5cm〜5cmの長繊維の集合体からなる炭化綿、3〜9M(Micronaire)の炭化綿、木綿から炭化綿への直径方向の収縮率が15〜30%であり、かつ焼成後の炭化綿が炭化セルロースの二重構造を備えている炭化綿が特に効果的である。
また、この炭化綿は木綿を200〜500°Cで加熱焼成することによって製造することができる。このように、先の発明によって得られる全ての炭化綿を使用することができる。
【0009】
【発明の実施の形態】
以下に、本発明を詳細に説明する。
布団、枕、シーツ、毛布、肌掛け等の医療介護用および一般用寝装具において、木綿を焼成することで得られた炭化綿を利用することにより、就寝中の人体から発する汗、臭い、垢などの他、介護時に飛沫汚染する涎、人尿、人糞等の臭いを効果的に吸収することができる。
また、この炭化綿は、適度に柔らかく褥瘡(床擦れ)を軽減することができるという優れた効果がある。さらに、多くの場合、医療および被介護者の寝装具は、シーツ等の直接触れるものを除き、共同使用されているが、炭化綿が抗菌性を有するので、このような共用寝具を介しての感染等の危険を著しく軽減することができる。
【0010】
本発明の寝装具は、仰臥姿勢を長時間保つものとして有用であり、また柔軟性を備えているので、医療および介護の為、被介護者が腹臥位および側臥位、座位、半座位など必要な姿勢を保つ場合にも好適である。本発明の寝装具は、木綿を窒素雰囲気下200〜500℃で加熱焼成して得た炭化綿を使用する。また、長時間の使用によって炭化綿が破壊し、粉末化し難いように、炭化綿をタオルとタオルの間に挟み込んで焼成することもできる。さらに、長時間の使用によって、破壊し、粉末化したものが、流失しないように、不織布あるいは目の細かい布で被うのが好ましい。これによって、加工時の綿あるいは炭化綿の粉塵を軽減することができる。
【0011】
(アンモニアの吸着性の評価)
上記の通り、医療あるいは要介護の現場では、就寝中の人体から発する汗、臭い、垢などの他、介護時に飛沫汚染する涎、人尿、人糞等悪臭の原因となる物質が寝具を汚し、悪臭の原因となっている。特にアンモニアの吸着性の比較を行った。
アンモニアは人体から発する体液が次第にバクテリアの働きによって生産されるものであり、悪臭の原因となっているが、このアンモニアガスの吸着力を調べた。
この場合、アンモニアガスを容積が555mLの密閉容器中に室温22°Cで充満飽和させ、炭化綿と10分間共存させた時のアンモニア量を、ガス検知管によって測定し、始めの量から吸着量(ppm)を測定したものである。
その結果を図1に示す。図1における白丸(○)は、比較のための木綿の布団(「コントロール」と表示)の場合、黒丸(●)は、本発明の炭化綿(400°Cで焼成)を使用した場合である。
図1において本発明の炭化綿の場合は、時間と共に急速にアンモニアガスが減少しているが、これは本発明の炭化綿の著しいアンモニアガスの吸着を示すものである。
【0012】
(メチルメルカプタンの吸着性評価)
アンモニアの他、悪臭の成分のひとつであるメチルメルカプタンについて、炭化綿の吸着力について調べた。容積が555mLの密閉容器中に室温22°Cで充満飽和させ、そのまま放置して、経時的にメチルメルカプタン量(ppm)を測定した。この場合の炭化綿は、1g使用した。
その結果を図2に示す。図2における白丸(○)は、比較のための同量の木綿布団(「コントロール」と表示)の場合、黒丸(●)は、本発明の炭化綿(400°Cで焼成)を使用した場合である。
図2において、本発明の炭化綿を使用した場合は、容器内のメチルメルカプタンが140分後も検知されない。これは本発明の炭化綿の著しいメチルメルカプタンの吸着を示すものである。
【0013】
次に、炭化綿の重量を変化させた時の吸着を調べた結果を図3に示す。炭化綿の重量を変えた以外は、上記図2の測定条件と同一である。
この図3に示すように、炭化綿の増加と共に急速にメチルメルカプタンが減少し、わずか0.3gでメチルメルカプタンの濃度は0ppmになった。これは、炭化綿の著しいメチルメルカプタンの吸着能を示すものである。
【0014】
(抗菌作用の評価)
本発明の炭化綿が抗菌作用を持つかどうかを調べた。焼成直後の炭化綿を無菌状態で、鋏で切り取り、5cm×5cmの大きさにした。厚みは約1cmであった。
一方、LB寒天培地(LBプレート)に大腸菌の一晩培養液0.1mLを塗布し、その中央に切り取った炭化綿を敷いた。比較のためのコントロールとしては、炭化綿の代わりにろ紙を敷いた。これらのプレートを37°Cで一夜培養した。
コントロールのプレートは、ろ紙を置いた部分を含め、全面に大腸菌が増殖していた。しかしながら、炭化綿を敷いたプレートでは、炭化綿を敷いた部分には、大腸菌は全く増殖しておらず、その他の部分は増殖しており、中央が抜けた状態になっていた。この事から、炭化綿には大腸菌の増殖を抑える働きがあることが解った。
【0015】
(医療介護用および一般用寝装具部材の製造法の例)
炭化綿を医療介護用および一般用寝装具部材としてそのまま加工すると、粉塵が大量に発生し、加工現場での作業能率が下がり、また、作業者の健康を害する恐れがある。これを防ぐために、あらかじめ加工がし易い形態を創案した。
すなわち、織物状の木綿、例えばタオルを木綿の上下に挟むようにし、これを焼成した。この作業は粉塵の発生を効率良く抑える事が出来た。
焼成が完了すると、焼成タオルを挟んだまま、目の小さい不織布で作成した袋様のシートで包み、シーラーによって密着した。これにより、焼成時に発生した粉体の流出を防ぐ事が確認できた。また、その後の使用によって発生する粉体の流出も防ぐ事ができることが確認できた。
【0016】
事前に炭化綿を必要な大きさで前加工しておくと、上記のように粉塵の発生による加工の困難さを軽減できる。製造上の指標とするために、焼成による木綿の重量および収縮率を測定した。重量変化の結果を表1に示す。
また、様々な形態で用意した木綿の焼成前と焼成後との差を取り、重量の変化を百分率で表わした。重量変化は平均で約25.5%であった。
収縮率は、用いた木綿織物の縦と横方向の長さの変化を、焼成前と焼成後の長さを測定して差を取り、収縮の度合いを百分率で表わした。結果その結果を表2に示す。収縮率は縦方向で76%、横方向で約80%であった。また、平均で77.5%であった。
以上から、収縮率を考慮して、実際の寝装具などのサイズを焼成前に調整することができる。

(生活排泄物の吸着性評価)
実際に炭化綿を封入したマット(幅85cm・丈65cm・厚さ10〜15mm、不織布で被い、さらに上部はキルティングした木綿シーツで被った。)を作製し、介護施設に導入して、その利用者の使用状態を従来品と比較した。
利用期間は1週間とし、その生活に伴う臭いについて、主として官能的(個人の五感により評価)に比較した。
その結果、利用者及び介護者のいずれも、従来よりも著しい臭気の低減効果を認め、炭化綿マットは生活によって生ずる様々な物質を吸収し、無臭化する効果を持つ事が確認できた。
【0020】
(褥瘡の緩和作用の評価)
上記と同じものを用い、介護利用者の褥瘡(床擦れ)について効果があるか調べた。その結果、炭化綿を用いたマットは活性炭を用いたマットと比べ、適度に柔らかく、褥瘡を軽減することが確かめられた。
【0021】
(その他)
本発明の医療あるいは介護用寝装具は、それ自体で寝装具に付着した悪臭物質などを効果的に吸着除去できる炭素質吸着材又は積層シートから製造できるが、従来の活性炭素繊維や吸着材との複合又は併用はなんら妨げるものではない。
【0022】
【発明の効果】
上記に示す通り、本発明の寝装具は就寝中の人体から発する汗、臭い、垢などの他、介護時に飛沫汚染する涎、人尿、人糞等の臭いを吸収し、かつ適度に柔らかく、医療および介護利用者の褥瘡(床擦れ)を軽減することができるという優れた効果を有する。

BACKGROUND OF THE INVENTION
The present invention absorbs odors such as sweat, odor, and dirt from the human body while sleeping, as well as sputum, human urine, human feces and the like that are splashed and contaminated during nursing care, and is moderately soft, and is a pressure ulcer for medical and nursing care users. The present invention relates to a bedding that can reduce (rubbed floor).
[0002]
[Prior art]
Bedding is an indispensable tool for human beings to sleep, rest or treat, and is used every day regardless of health, unhealth, and age. For this reason, it is forced to be used for a long time, and is gradually contaminated with metabolites emitted from humans, such as sweat and dirt.
In particular, for a sick person who needs treatment or a person who receives care, in addition to being contaminated with sputum, urine, stool, etc., she may be contaminated by missing a meal to become a place to eat. However, in the long history of mankind, the same equipment used for sleeping has been diverted to medical care and nursing care, and the situation remains the same in modern times. This is because bedtime is overwhelmingly long in medical care and nursing care, and the time spent in the supine position occupies most of the life time.
[0003]
If the same bedding is used for a long time, pressure ulcers (bed rubbing) have become a big problem for those who receive care such as sick people and elderly people. This floor rubbing is a state in which a certain posture continues for a long time, so that the skin and subcutaneous tissue are necrotized in the body part subjected to the pressure by clothing and bedding.
Causes of occurrence include pressure due to body weight, friction, wetness and dryness of the skin, edema, malnutrition, anemia, paralysis, motor paralysis, consciousness disturbance and incontinence.
For prevention, the cause of pressure is removed, but there are water mats, air mats, bead mats, round seats, etc. as decompression supplies, these are the back of the head, scapula, sacrum, buttocks, where pressure ulcers can easily occur Auxiliary tools are applied to the protruding parts of the bone, such as the (heel), greater trochanter (inner thigh), and outer ankle (ankle) to disperse the pressure.
However, there is no material that can deodorize and adjust humidity while reducing pressure. As shown in the examples above, many of these required properties are in conflict.
[0004]
Conventionally, as a material for a futon among beddings, cotton (silk cotton), wool, and feathers (down) have been used as cotton and luxury products as popular products. In modern times, the materials of high-grade products have not changed much, but lighter and cheaper synthetic fibers and urethane, a mixture of synthetic fibers and cotton, or imported cheap waterfowl feathers are used for popular products.
Although cotton as a futon is highly hygroscopic, it absorbs moisture during use and gradually increases in weight, and mold and mites are generated. Was essential to maintain.
On the other hand, buckwheat husks have been used for pillow materials until several decades ago, but Western lifestyle has been introduced, and thin and large shapes are common. Plastic is used.
[0005]
Some futons and pillows are coated with antibacterial substances in consideration of hygiene, but they have little effect of deodorizing absorbed sweat, dirt, etc., especially for medical and nursing users. The patient's odor is transferred to the bedding to be used, and a normal odor is emitted with use.
In addition, many products are difficult to dispose of, and in particular, the ones that improve the performance, such as hygiene, deodorant effect, and antibacterial effect, have a tendency to be remarkable and even become social problems.
[0006]
[Problems to be solved by the invention]
An object of the present invention is a method for producing a bedding and a material for bedding that is highly hygroscopic, has a deodorizing action, has antibacterial properties, is light, relieves body pressure, and is also environmentally friendly The purpose is to provide.
Here, bedding means bedding, pillows, sheets, blankets, skin bedding, etc., Tanma, sleepwear, etc., and those used for medical care and those used in general households. Means and encompasses these.
[0007]
[Means for Solving the Problems]
As a result of intensive studies to achieve the above object, the present inventor has obtained knowledge that the above problem can be solved by using a carbon fiber material obtained by firing cotton.
The present invention is based on this finding.
1. Carbonized cotton with a double structure of carbonized carbon , which is obtained by sandwiching a cotton fabric, which becomes carbonized cotton, between towels and heating and baking it at 200 to 500 ° C. in a nitrogen atmosphere does not diffuse fine powder attached to the carbonized cotton. As described above, a futon, pillow, bed sheet, blanket, skin cover, bedding such as Tanzen, etc., characterized by being covered with a fine cloth or non-woven fabric and used.
[0008]
The present inventor previously proposed “carbonized cotton and a method for producing the same” (Japanese Patent Application No. 2001-020138) (the previous invention). The carbonized cotton obtained by firing cotton used for the medical care and general bedding of the present invention is used for the medical care and general bedding focusing on the adsorption power of the carbonized cotton according to the invention of the prior application.
For application to medical care and general bedding, carbonized cotton obtained by firing cotton is effective, especially carbonized cotton consisting of an aggregate of long fibers having an average diameter of 5 to 15 μm, average length of 0.5 cm Carbonized cotton consisting of aggregates of ˜5 cm long fibers, carbonized cotton of 3-9M (Micronaire), shrinkage in the diameter direction from cotton to carbonized cotton is 15-30%, and carbonized cotton after firing is carbonized Carbonized cotton having a double structure of cellulose is particularly effective.
Moreover, this carbonized cotton can be manufactured by heat-firing cotton at 200-500 degreeC. Thus, all the carbonized cotton obtained by the previous invention can be used.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The present invention is described in detail below.
By using carbonized cotton obtained by baking cotton in medical care and general bedding such as futons, pillows, sheets, blankets, skin covers, etc., sweat, odors, and dirt emitted from the sleeping human body In addition to the above, it is possible to effectively absorb odors such as sputum, human urine, and human feces that are splashed and contaminated during care.
Further, this carbonized cotton has an excellent effect that it is moderately soft and can reduce pressure ulcers (flooring). In addition, in many cases, bedding for medical care and care recipients is used together except for items that are directly touched, such as sheets, but carbonized cotton has antibacterial properties. The risk of infection can be significantly reduced.
[0010]
The bedding of the present invention is useful for maintaining a supine posture for a long time and also has flexibility, so that a care recipient is in a prone position, a lateral position, a sitting position, a semi-sitting position, etc. for medical care and nursing care. It is also suitable for maintaining a necessary posture. The bedding of the present invention uses carbonized cotton obtained by heating and baking cotton at 200 to 500 ° C. in a nitrogen atmosphere. In addition, the carbonized cotton can be sandwiched between towels and baked so that the carbonized cotton is destroyed by long-time use and is not easily powdered. Furthermore, it is preferable to cover with a non-woven fabric or a fine-grained cloth so that those which are broken and powdered by long-term use will not be washed away. Thereby, the dust of cotton or carbonized cotton during processing can be reduced.
[0011]
(Evaluation of ammonia adsorption)
As mentioned above, in the field of medical care or nursing care, in addition to sweat, odor, dirt, etc. from the sleeping human body, substances that cause odors such as sputum, human urine, human excrement, etc. , Causing odors. In particular, the adsorption of ammonia was compared.
Ammonia is a body fluid produced by the human body, which is gradually produced by the action of bacteria and causes odor. The adsorption power of ammonia gas was investigated.
In this case, ammonia gas is filled and saturated at a room temperature of 22 ° C in a sealed container having a volume of 555 mL, and the amount of ammonia when coexisting with carbonized cotton for 10 minutes is measured with a gas detector tube. (Ppm) was measured.
The result is shown in FIG. In FIG. 1, the white circle (◯) is a comparison cotton blanket (indicated as “control”), and the black circle (●) is the case of using the carbonized cotton of the present invention (fired at 400 ° C.). .
In FIG. 1, in the case of the carbonized cotton of the present invention, the ammonia gas rapidly decreases with time, which indicates the remarkable adsorption of ammonia gas of the carbonized cotton of the present invention.
[0012]
(Adsorption evaluation of methyl mercaptan)
In addition to ammonia, methyl mercaptan, which is one of the malodorous components, was investigated for the adsorptive power of carbonized cotton. A closed container having a volume of 555 mL was filled and saturated at room temperature of 22 ° C., left as it was, and the amount of methyl mercaptan (ppm) was measured over time. In this case, 1 g of carbonized cotton was used.
The result is shown in FIG. In FIG. 2, white circles (◯) indicate the same amount of cotton duvet for comparison (indicated as “control”), and black circles (●) indicate the case of using the carbonized cotton of the present invention (fired at 400 ° C.). It is.
In FIG. 2, when the carbonized cotton of the present invention is used, methyl mercaptan in the container is not detected even after 140 minutes. This shows the remarkable methyl mercaptan adsorption of the carbonized cotton of the present invention.
[0013]
Next, the results of examining the adsorption when the weight of carbonized cotton is changed are shown in FIG. The measurement conditions are the same as those in FIG. 2 except that the weight of the carbonized cotton is changed.
As shown in FIG. 3, methyl mercaptan decreased rapidly with the increase in carbonized cotton, and the concentration of methyl mercaptan became 0 ppm with only 0.3 g. This indicates the remarkable ability of carbonized cotton to adsorb methyl mercaptan.
[0014]
(Evaluation of antibacterial action)
Whether the carbonized cotton of the present invention has an antibacterial action was examined. The carbonized cotton immediately after baking was aseptically cut with a scissors to a size of 5 cm × 5 cm. The thickness was about 1 cm.
On the other hand, 0.1 mL of an overnight culture of E. coli was applied to an LB agar medium (LB plate), and cut carbonized cotton was spread on the center. As a control for comparison, filter paper was laid instead of carbonized cotton. These plates were incubated overnight at 37 ° C.
The control plate had E. coli grown on the entire surface, including the part where the filter paper was placed. However, in the plate laid with carbonized cotton, E. coli did not grow at all in the part laid with carbonized cotton, and the other parts had grown, and the center was in a state of being lost. From this, it was found that carbonized cotton has a function of suppressing the growth of E. coli.
[0015]
(Example of manufacturing methods for medical care and general bedding members)
If carbonized cotton is processed as it is as a medical care and general bedding member, a large amount of dust is generated, the work efficiency at the processing site is lowered, and the health of the worker may be impaired. In order to prevent this, an easy-to-process form was created in advance.
That is, woven cotton, such as a towel, was sandwiched between the upper and lower sides of the cotton and baked. This work was able to efficiently suppress the generation of dust.
When the baking was completed, it was wrapped with a bag-like sheet made of a non-woven fabric with small eyes, with a baking towel in between, and adhered with a sealer. Thereby, it was confirmed that the powder outflow generated during firing was prevented. Further, it was confirmed that the powder outflow generated by subsequent use can be prevented.
[0016]
If the carbonized cotton is pre-processed in a necessary size in advance, the difficulty of processing due to generation of dust can be reduced as described above. In order to make it an index for production, the weight and shrinkage ratio of cotton by firing were measured. The results of weight change are shown in Table 1.
Moreover, the difference between before and after firing of cotton prepared in various forms was taken and the change in weight was expressed in percentage. The average weight change was about 25.5%.
For the shrinkage rate, the change in length in the vertical and horizontal directions of the cotton fabric used was measured by measuring the length before and after firing, and the degree of shrinkage was expressed as a percentage. Results The results are shown in Table 2. The shrinkage was 76% in the vertical direction and about 80% in the horizontal direction. Moreover, it was 77.5% on average.
From the above, it is possible to adjust the size of an actual bedding or the like before firing in consideration of the shrinkage rate.

(Evaluation of adsorptive properties of daily excrement)
A mat (with a width of 85 cm, a length of 65 cm, a thickness of 10-15 mm, covered with a non-woven fabric, and covered with a quilted cotton sheet) was introduced into a nursing facility, The usage state of the user was compared with the conventional product.
The period of use was one week, and the odor associated with the life was mainly compared to sensual (evaluated by the individual five senses).
As a result, both users and caregivers recognized a remarkable odor reduction effect than before, and it was confirmed that the carbonized cotton mat has the effect of absorbing various substances generated by life and making it non-bromide.
[0020]
(Evaluation of pressure ulcer relief)
The same thing as the above was used, and it was investigated whether there was an effect about the pressure ulcer (rubbing) of a care user. As a result, it was confirmed that the mat using carbonized cotton was moderately soft and reduced pressure ulcer compared to the mat using activated carbon.
[0021]
(Other)
The medical or nursing bedding of the present invention can be manufactured from a carbonaceous adsorbent or laminated sheet that can effectively adsorb and remove malodorous substances adhering to the bedding by itself. This combination or combination does not interfere with the use.
[0022]
【The invention's effect】
As shown above, the bedding of the present invention absorbs odors such as sweat, odor, and dirt from the human body while sleeping, as well as sputum, human urine, human feces, etc. It has an excellent effect of being able to reduce pressure ulcer (rubbing) of medical and care users.
