本発明は、酸素富化手段を備えた便座装置に関し、特に排便促進機能を有する便座装置に関するものである。 The present invention relates to a toilet seat device provided with oxygen enriching means, and more particularly to a toilet seat device having a defecation promoting function.
従来、排便促進機能を有する便座装置は、特許文献１に代表されるように、排便行為の際に力むことがないように、洗浄水の強さを強弱と繰り返して局部に向けて噴出し、一種のマッサージ効果によって排便行為をスムーズに行えるような工夫がされてきた。
また、トイレ空間内の酸素不足を防止し、酸素濃度を一定に保つために、トイレ空間内に酸素富化装置を設けたものもあった。
In some cases, an oxygen enrichment device is provided in the toilet space to prevent oxygen shortage in the toilet space and to keep the oxygen concentration constant.
上記従来の便座装置は、使用者が便意を感じている時に洗浄水によるマッサージの刺激によって排便を促しサポートするもので、便秘の原因そのものを解消するためのものではなかった。また、トイレ空間内に酸素富化装置を設ける目的は、狭いトイレ空間内の酸素濃度を一定に保つことで心肺への負担を軽減することにあり、排便を促進および便秘の原因を改善するために設けられたものではなかった。 The above-described conventional toilet seat device promotes and supports defecation by stimulating massage with washing water when the user feels constipation, and is not intended to eliminate the cause of constipation. The purpose of installing an oxygen enrichment device in the toilet space is to reduce the burden on the heart and lungs by keeping the oxygen concentration in the narrow toilet space constant, in order to promote defecation and improve the cause of constipation It was not provided.
一般に便秘には、慢性的なものや、ストレスや緊張などによる神経性のもの、偏食など食生活の乱れによるもの、腸などの病気が原因で起こるもの、排便を行なうための筋力不足によるもの等さまざまな原因があり、さらに慢性的な便秘においては、便意を我慢する行為を繰り返すことで、便意に対する反応が鈍り便意を感じにくくなることもあった。このように便秘の原因が食生活や病気、筋力不足などに起因する場合は、使用者自らが便秘原因の解消を行なわなくてはならないが、便秘の原因がストレスや緊張などによる神経性のものの場合は使用者のみでは、改善しにくいものであった。 In general, constipation is chronic, nervous, due to stress or tension, unbalanced diet, disorder due to intestinal illness, intestinal illness, lack of muscle strength for defecation, etc. There are various causes, and in chronic constipation, by repeating the act of enduring constipation, the response to constipation may become dull and it may be difficult to feel constipation.

Thus, the oxygen enrichment means 7 is controlled.
すなわち、制御手段２０は、演算手段１７からの比較信号に応じて酸素富化空気の量および濃度を、使用者が最もリラックスできる状態に酸素富化手段７を制御できるように予め実験的に求めたデータをテーブル表として記憶部に格納しており、従って演算手段１７からの比較信号に基づき、これに対応する値を格納部から取り出した制御信号により酸素富化手段７を制御し、使用者が最もリラックスできる状態に酸素富化手段７の運転を行なうように構成している。 That is, the control means 20 experimentally obtains the amount and concentration of oxygen-enriched air in advance in accordance with the comparison signal from the computing means 17 so that the oxygen-enriching means 7 can be controlled in a state where the user can be most relaxed. The data is stored in the storage unit as a table, and therefore, based on the comparison signal from the calculation unit 17, the oxygen enrichment unit 7 is controlled by the control signal obtained from the storage unit for the corresponding value. Is configured to operate the oxygen-enriching means 7 in the most relaxed state.
以上のように構成された酸素富化機能付き便座装置について、以下その動作、作用を説明する。トイレ室に入ってきた使用者が用便に必要な脱衣をして便座３に座り、ヘッドセット１２を頭部に装着すると、耳掛け部１３に設けた心拍検出手段１６が使用者の耳上部に密着し、使用者の頭部から心機図を検出する。そして、演算手段１７は、心拍検出手段１６による心機図から、ピーク間間隔を求め心拍系列データを作成し、時系列データの周波数解析を行なう。そして得られた周波数データより、高周波成分および低周波成分を求め使用者の緊張弛緩状態を評価する。 About the toilet seat apparatus with an oxygen enrichment function comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. When the user who has entered the toilet room undresses necessary for the toilet and sits on the toilet seat 3 and wears the headset 12 on the head, the heartbeat detecting means 16 provided on the ear hook 13 is the upper part of the user's ear. The heart mechanism diagram is detected from the user's head. Then, the calculating means 17 obtains the interval between peaks from the heartbeat diagram by the heartbeat detecting means 16 to create heartbeat series data, and performs frequency analysis of the time series data. Then, a high frequency component and a low frequency component are obtained from the obtained frequency data, and the user's tension / relaxation state is evaluated.
このようにして演算手段１７で得られた使用者Ａの緊張弛緩状態の評価信号とフィードバック信号との比較信号から、使用者が緊張状態にあると判定した時に、この判定信号を受けた制御手段２０が酸素富化手段７を運転し、ホース１１を介してヘッドセット１２の酸素富化空気口元吐出口１４より使用者Ａに酸素富化空気を供給する。ここで、酸素富化膜により酸素富化空気が得られる原理について説明する。 Control means that receives the determination signal when it is determined that the user is in a tension state from the comparison signal between the evaluation signal of the tension / relaxation state of the user A and the feedback signal obtained by the calculation means 17 in this way. 20 operates the oxygen-enriching means 7 and supplies oxygen-enriched air to the user A through the hose 11 from the oxygen-enriched air port former discharge port 14 of the headset 12. Here, the principle of obtaining oxygen-enriched air by the oxygen-enriched film will be described.
酸素富化膜は有機高分子の平膜により構成され、膜を通過する分子の速度の差を利用するもので、空気中の窒素に比べ酸素をよく通す膜を使用することで、膜通過前よりも酸素濃度が高い酸素富化空気を得ることができる。通常の空気において酸素濃度は約２１％（窒素約７９％）であり、生成される酸素富化空気の酸素濃度や風量は、酸素富化膜の形態、大きさなどによって変わるが、本実施例では、酸素富化膜を通過後の酸素富化空気の酸素濃度が約３０％（窒素約７０％）となるものを用いている。 An oxygen-enriched membrane is composed of a flat membrane of organic polymer and uses the difference in the speed of molecules passing through the membrane. By using a membrane that passes oxygen better than nitrogen in the air, Thus, oxygen-enriched air having a higher oxygen concentration can be obtained. In ordinary air, the oxygen concentration is about 21% (about 79% nitrogen), and the oxygen concentration and air volume of the oxygen-enriched air produced vary depending on the form and size of the oxygen-enriched film, but this embodiment However, the oxygen concentration of the oxygen-enriched air after passing through the oxygen-enriched film is about 30% (nitrogen is about 70%).
酸素富化膜を複数並列してつなげることで、より酸素濃度の高い空気を得ることも可能である。一般に酸素富化空気の吸引には、リフレッシュ効果やリラクゼーション効果があることが知られており、酸素富化空気を吸引することで使用者Ａの緊張状態を緩和することができる。 It is also possible to obtain air with a higher oxygen concentration by connecting a plurality of oxygen-enriched membranes in parallel. Generally, it is known that the suction of oxygen-enriched air has a refreshing effect and a relaxation effect, and the tension state of the user A can be relieved by sucking the oxygen-enriched air.
精神的に緊張した状態では、排便がスムーズに行なわれないことは周知の事実であり、排便をスムーズに行なうためには自律神経の興奮緩和が必要であることから、酸素富化空気を吸引することで使用者の緊張状態を緩和し、排便をスムーズに行なうことができる。 It is a well-known fact that defecation is not carried out smoothly in a mentally tensioned state, and since the excitement of the autonomic nerve is necessary to carry out defecation smoothly, oxygen-enriched air is aspirated Therefore, the tension state of the user can be eased and defecation can be performed smoothly.
さらに、酸素富化空気を吸引した使用者Ａの緊張緩和状態に応じて生体情報収集手段１６ａによるデータに基づく演算手段１７の評価信号と制御手段２０からの酸素富化手段７に対する制御信号のフィードバックを比較した演算手段１７の比較信号により、制御手段２０は再び酸素富化手段７の運転を制御することで、よりリラクゼーション効果を高めることができる。すなわち、生体情報収集手段１６ａによる使用者Ａの緊張弛緩状態に応じた演算手段１７の評価に応じて、酸素濃度可変手段１８と流量調整手段１９を制御手段２０が制御し、酸素富化空気の流量や濃度を可変し、使用者が最もリラックスできる状態に
酸素富化手段７の運転を行なうものである。
Furthermore, the evaluation signal of the calculation means 17 based on the data by the biological information collection means 16a and the control signal feedback from the control means 20 to the oxygen enrichment means 7 according to the tension relaxation state of the user A who sucked the oxygen enriched air. The control means 20 can control the operation of the oxygen enrichment means 7 again by the comparison signal of the calculation means 17 that compares the above, so that the relaxation effect can be further enhanced. That is, the control means 20 controls the oxygen concentration varying means 18 and the flow rate adjusting means 19 according to the evaluation of the computing means 17 according to the tension relaxation state of the user A by the biological information collecting means 16a, and the oxygen enriched air The oxygen enrichment means 7 is operated in such a way that the flow rate and concentration can be varied and the user can be most relaxed.
このように、本実施の形態では酸素富化空気を吸引することで使用者の緊張状態を緩和し、便秘の原因そのものを取り除くことで排便を促進することができる。 Thus, in this Embodiment, a user's tension | tensile_strength state is eased by attracting | sucking oxygen-enriched air, and defecation can be accelerated | stimulated by removing the cause of constipation itself.
なお、使用者Ａによる酸素富化空気の吸引は、従来からの洗浄水による肛門刺激による排便促進を阻害するものではなく、本実施の形態では記載していないが、洗浄水による肛門刺激を組み合わせることでも、さらに排便促進効果を高めることができる。 Note that the suction of oxygen-enriched air by the user A does not inhibit the promotion of defecation by the conventional anal stimulation by the washing water and is not described in the present embodiment, but the anal stimulation by the washing water is combined. Even so, the effect of promoting defecation can be further enhanced.
また、本実施の形態では生体情報収集手段として圧電センサー１５を用いて、心拍を収集したが、ヘッドセット１２の左右に電極を設け、左右耳上部の電位差から心電図を検出する方法や、光学式脈波センサを設け、脈波から心拍を検出する方法を用いても本実施の形態と同様の効果を得ることができる。 In the present embodiment, the heart rate is collected using the piezoelectric sensor 15 as the biological information collecting means. However, a method of detecting an electrocardiogram from the potential difference between the left and right ears by providing electrodes on the left and right of the headset 12, or an optical type Even if a pulse wave sensor is provided and a method of detecting a heartbeat from the pulse wave is used, the same effect as in the present embodiment can be obtained.
さらに、酸素富化空気の供給方法としては、酸素富化膜を用いる以外にも、水を電気分解して酸素を生成する方法や、吸着剤を用いて酸素富化空気を供給する方法などを用いることができ、酸素富化空気の供給方法の違いにより、排便促進効果に差が出るものではない。 Furthermore, as a method for supplying oxygen-enriched air, besides using an oxygen-enriched membrane, a method for electrolyzing water to generate oxygen, a method for supplying oxygen-enriched air using an adsorbent, etc. It can be used, and there is no difference in the effect of promoting defecation due to the difference in the supply method of oxygen-enriched air.
また、本実施の形態では、ヘッドセット１２を用いて使用者Ａに酸素富化空気を供給することで、使用者の動きや姿勢にとらわれることなく確実に酸素富化空気を供給することができる。 Further, in the present embodiment, by supplying oxygen enriched air to the user A using the headset 12, the oxygen enriched air can be reliably supplied without being caught by the user's movement and posture. .
また、ヘッドセット１２に生体情報収集手段１６ａを設けたので、使用者Ａに負担をかけずに、使用者の動きや姿勢にとらわれることなく確実に生体情報を収集することができる。 Further, since the biological information collecting means 16a is provided in the headset 12, the biological information can be reliably collected without imposing a burden on the user A and without being restricted by the movement and posture of the user.
また、酸素富化手段７の運転方法による使用者の緊張弛緩状態をフィードバックしながら、酸素濃度や流量を可変することで、使用者が最もリラックスできる状態に酸素富化手段７の運転を行なうことができる。 Further, the oxygen enrichment means 7 is operated in a state where the user can be most relaxed by changing the oxygen concentration and flow rate while feeding back the tension relaxation state of the user according to the operation method of the oxygen enrichment means 7.
