【発明の詳細な説明】
［技術分野」
本発明は、大気から酸素濃度の高められた空気を得るた
めの装置に関するものであり、特に医療用として使用す
るのに適した酸素濃縮器に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a device for obtaining air with increased oxygen concentration from the atmosphere, and in particular to an oxygen concentrator suitable for medical use.
ざらに詳細には、本発明は特に医療用酸素濃縮器におい
て患者の近くで運転使用される際に重要な問題となる騒
音の発生を抑制するための改良を加えたものである。More specifically, the present invention provides improvements to suppress the generation of noise, which is an important problem especially in medical oxygen concentrators when they are operated near patients.
［従来技術］
医療用酸素濃縮器は家庭・病院等で患者の枕もと近くで
夜間でも使用するため、低騒音であることが必須の条件
として要求されることが多い。[Prior Art] Since medical oxygen concentrators are used at home, in hospitals, etc., near the patient's bedside, even at night, low noise is often required as an essential condition.
酸素濃縮には主として例えば真空ポンプを使用した酸素
濃縮器と、圧縮機等の加圧ポンプ類を使用した吸着型酸
素濃縮器の２種類があるが、真空ポンプと加圧ポンプの
ポンプ手段の違いにより、一般には模型の方が騒音のレ
ベルを低くしやすく、家庭用に適している。しかし従来
の酸素濃縮器では裏型酸素濃縮器においても騒音の対策
が不充分なため、未だ充分低騒音レベルに到達していな
いとされる場合がある。There are two main types of oxygen concentrators: oxygen concentrators that use vacuum pumps, and adsorption oxygen concentrators that use pressure pumps such as compressors, but there are differences in pumping means between vacuum pumps and pressure pumps. Therefore, models are generally easier to reduce noise levels and are suitable for home use. However, in conventional oxygen concentrators, even in back-type oxygen concentrators, measures against noise are insufficient, so it is sometimes said that a sufficiently low noise level has not yet been achieved.
騒音を低減する方策としては、一般に騒音源を゛遮音壁
で密閉する方法や騒音源の振動を防止して固体伝播音を
減少させる方法、内壁面に吸音材を貼付けて音の減衰を
図る方法等が知られている。Measures to reduce noise generally include methods such as sealing the noise source with a sound insulating wall, reducing structure-borne sound by preventing vibration of the noise source, and attaching sound-absorbing materials to internal walls to attenuate sound. It has been known.
従来の酸素濃縮器においても、上記の騒音対策が取入れ
られているが充分な効果をあげるに至りていない。例え
ば騒音源を密閉する遮音壁については、遮音性を高める
ためには遮音壁の質量を増加させる必要があるが、必要
以上に壁の肉厚を大きくすると装置の重量寸法が増加し
て好ましくない。Conventional oxygen concentrators have also adopted the above-mentioned noise countermeasures, but have not achieved sufficient effects. For example, in the case of a sound insulating wall that seals a noise source, it is necessary to increase the mass of the sound insulating wall in order to improve sound insulation, but if the wall thickness is increased more than necessary, the weight and dimension of the device will increase, which is undesirable.
また通常、酸素濃縮器においてポンプ手段の冷却用に多
量の空気流れが必要とされるが、その空気の流入口・流
出口から出る音が壁を透過する音よりも大きくなれば、
装置全体の騒音レベルは空気流路から出る音が律速にな
るため、遮音壁の効果が出にくくなる。Oxygen concentrators also typically require a large amount of air flow to cool the pumping means, and if the sound coming from the air inlet and outlet is louder than the sound transmitted through the walls,
Since the noise level of the entire device is determined by the sound emitted from the air flow path, the effect of the sound insulating wall becomes less effective.
さらに空気流路の内壁に吸音材を貼りつけることについ
ても、流路の断面積を絞りすぎて、流路抵抗を増やし過
ぎると、流れる空気量が減少して、ポンプの冷却不足等
の不都合を生じることがある。Furthermore, when attaching sound absorbing material to the inner wall of the air flow path, if the cross-sectional area of the flow path is narrowed too much and the flow path resistance is increased too much, the amount of air flowing will decrease, causing problems such as insufficient cooling of the pump. This may occur.
そのため従来の酸素濃縮器では酸素濃縮性能を維持しつ
つ、かつ重量寸法を増大させないで充分な騒音対策をと
ることが困難であった。Therefore, with conventional oxygen concentrators, it has been difficult to take sufficient noise countermeasures while maintaining oxygen concentrating performance and without increasing weight and dimensions.
最近かかる問題点の有効な解決策として、空気の流入通
路と流出通路の各々を５回以上屈曲させること等が提案
されている（特開昭６１−１５５２０４ ）。Recently, as an effective solution to this problem, it has been proposed to bend each of the air inflow passage and the air outflow passage five or more times (Japanese Patent Laid-Open No. 155204/1983).
ただし重病患者等が使用する際にさらに騒音発生の少な
い酸素濃縮器が要望され、そのための改善がさらに望ま
れる場合がある。However, when used by seriously ill patients, there is a demand for oxygen concentrators that generate even less noise, and further improvements may be desired.
［発明の目的］
本発明の目的は上記の従来技術の欠点を是正し、従来の
酸素濃縮器と比べ重量・寸法をほとんど増加させること
なく、又、濃縮器の機能を減じることな〈従来よりさら
に騒音の小さい改善された酸素濃縮器を提供することに
ある。[Object of the Invention] The object of the present invention is to correct the above-mentioned drawbacks of the prior art, and to improve the efficiency of oxygen concentrators without increasing the weight or dimensions of the conventional oxygen concentrator or reducing the function of the concentrator. Another object of the present invention is to provide an improved oxygen concentrator with less noise.

The inventors have discovered that it is effective to dissipate the heat generated within the box to the outside of the box using a heat pipe, and have arrived at the present invention.

Although water is usually practical as the liquid to be sealed, an aqueous solution containing an antifreeze agent or an organic heat medium other than aqueous salt may also be used. It is desirable to prevent corrosion by using a corrosion-resistant material in the heat pipe or by including a corrosion inhibitor in the sealed liquid. The heat pipe can be installed horizontally, but especially when a sealed liquid is used, it should be slightly inclined to facilitate convection of the filled liquid and increase heat exchange efficiency. Nono is preferable.

に収納されていることを特徴とするものである。Further, the adsorption type oxygen concentrator, which is one of the preferred embodiments of the present invention, will be explained in more detail. One example is a pressure fluctuation adsorption type oxygen concentrator equipped with a compressor and two adsorption beds filled with an adsorbent that adsorbs nitrogen more easily than oxygen, such as zeolite 5A and zeolite 13X. By alternately supplying the air compressed by the compressor to the two adsorption beds, for example via a three-way automatic valve, nitrogen can be selectively adsorbed, resulting in 90% oxygen.
% oxygen-enriched gas is discharged from each adsorption bed. Furthermore, a storage tank for storing the oxygen-enriched gas obtained in this manner is also provided. Furthermore, for the adsorption bed that has completed the adsorption process, for example, the compressed gas in the bed is released in the opposite direction to the air supply direction, and furthermore, the oxygen-enriched gas from the storage tank is purged to perform desorption and regeneration. Equipped with automatic on-off valves, etc. In addition, it is used for medical purposes by people to strengthen their breathing. In some cases, the oxygen-enriched gas flowing out from the storage tank passes through a pressure reduction adjustment means, a flow I adjustment means, a sterilization filter, etc., and then passes through a humidification means such as a bubbling method to be humidified and used. It has become. Such an adsorption oxygen concentrator is
It is characterized in that the compressor is housed in a storage box equipped with the heat pipe as described above.
