本発明は、患者へ及び患者からの呼吸気の流れ６ を制
御する人工呼吸装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an artificial respirator that controls the flow of respiratory air 6 to and from a patient.
〈従来技術〉
人工呼吸袋＠は、酸素濃度設定部にて人工呼吸に使用し
ている際の酸素濃度を２１〜１００％の範囲で任意に設
定できるようにしている。<Prior Art> The artificial respiration bag@ has an oxygen concentration setting section that allows the oxygen concentration during use for artificial respiration to be arbitrarily set in the range of 21 to 100%.
ところで、従来の人工呼吸装置は呼吸気の流量を付属の
流量センサにて検知しているが、該流量センサは同じ体
積であっても気体中の酸素濃度によって異なる体積を示
す。これは、気体の流量を熱線冷却され具合で感知する
ためで、気体の組成の相違（例えば酸素２１％と１００
％）によって熱線の冷却度が変化するためである。By the way, although conventional artificial respiration devices detect the flow rate of respiratory gas using an attached flow rate sensor, the flow rate sensor indicates a different volume depending on the oxygen concentration in the gas even if the volume is the same. This is because the flow rate of the gas is detected by the degree of heat ray cooling, and the difference in gas composition (for example, 21% oxygen and 100% oxygen) is required.
This is because the degree of cooling of the hot wire changes depending on the temperature (%).
そのため、人工呼吸装置の流量センサーが５００ｃｃ
ｋ−示しているにも拘らず、実際の呼吸気の流量は５１
０ ｃｃ であること等が発生し、人体を扱うものとし
ては安全上望ましくない。Therefore, the flow rate sensor of the artificial respirator is 500cc.
k- Despite the indication, the actual flow rate of respiratory air is 51
0 cc, etc., which is not desirable in terms of safety when handling human bodies.
〈発明の目的〉
本発明は上記の問題点を解決するもので、酸素濃度の設

吸気流量を外部より認識し得るようにした人工呼吸装置
全提供することを目的とする。<Object of the Invention> The present invention solves the above-mentioned problems, and has a function of detecting a set value of oxygen concentration and correcting all measured values of a respiratory air flow rate measurement unit such as a flow rate sensor based on the set value. An object of the present invention is to provide an entire artificial respiration device which is provided so that the true respiratory airflow rate can be recognized from the outside.
〈実施例〉 本発明の構成を図面を参照しつつ述べる。<Example> The configuration of the present invention will be described with reference to the drawings.
第１図は本発明の実施例に係る人工呼吸装置のブロック
構成図である。FIG. 1 is a block diagram of an artificial respiration apparatus according to an embodiment of the present invention.
同図において、１は空気（Ａｉｒ）−酸素（ｏ２）混合
器であり、酸素濃度設定ツマミＫによって空気。In the figure, reference numeral 1 denotes an air-oxygen (O2) mixer, and the oxygen concentration setting knob K controls the air concentration.
酸素の入力が調節されて、設定した酸素濃度の呼吸気（
混合ガス）が製造される。The oxygen input is adjusted to provide the set oxygen concentration in the breathing air (
mixed gas) is produced.
前記空気−酸素混合器Ｉで製造された呼吸気はチューブ
にて患者接続部分捷で配送されそこから出力されるが、
その配送途中に設けられた流量センサ２にて該チューブ
中を流れる呼吸気の流量が測定される。The respiratory gas produced by the air-oxygen mixer I is delivered through a tube to the patient connection part and output from there,
A flow rate sensor 2 provided during the delivery measures the flow rate of respiratory air flowing through the tube.
一方、前記空気−酸素混合器】の酸素濃度ツマミにの設
定値は後述の検知手段にて検知され、その設定値情報（
酸素の％濃度）が補正装置３へ伝達される。そこで、該
補正装置３は前述した流量センサ２の呼吸気の流量信号

量データとして出力表示する。On the other hand, the setting value of the oxygen concentration knob of the air-oxygen mixer is detected by the detection means described later, and the setting value information (
% concentration of oxygen) is transmitted to the correction device 3. Therefore, the correction device 3 corrects the flow rate signal of the respiratory air from the flow rate sensor 2 described above using the set value information, and outputs and displays the corrected flow rate value as flow rate data.
さて、酸素濃度ツマミにの設定値の検知手段は次の通り
である。Now, the means for detecting the set value of the oxygen concentration knob is as follows.
即ち、酸素濃度ツマミには、第２図に示す如く、ツマミ
本体４と該ツマミ本体４の回転中心軸と同じ軸に取り付
けられたコード板５とから成っている。該コード板５は
コードに対するスリットが穿設されである。That is, as shown in FIG. 2, the oxygen concentration knob consists of a knob body 4 and a code plate 5 attached to the same axis as the rotation center axis of the knob body 4. The cord plate 5 is provided with a slit for the cord.
そして、６はフォトインタラプタによるスリットセンサ
ーで、前記混合器１に設けられており、所望の酸素濃度
に設定するため酸素濃度設定ツマミ■（のツマミ本体４
を回転させるとそれと一緒に回転するコード板５のスリ
ットを読み取り、前記ツマミ本体４の設定位置をコード
化して前記補正装置３へ出力するのである。Reference numeral 6 denotes a slit sensor using a photo-interrupter, which is installed in the mixer 1, and is used to set the oxygen concentration setting knob (knob body 4) to a desired oxygen concentration.
When the knob body 4 is rotated, a slit in the code plate 5 that rotates with the rotation is read, and the set position of the knob body 4 is encoded and output to the correction device 3.
なお、前記補正装置３はツマミ本体４の設定位置のコー
ドと酸素濃度の関係を予めテーブルとしてメモリしてい
るため、読み込んだコードから濃度設定ツマミにの位置
つ１り設定された酸素濃度を知ることができる。Since the correction device 3 stores in advance the relationship between the code of the setting position of the knob body 4 and the oxygen concentration as a table, it can know the oxygen concentration set for each position of the concentration setting knob from the read code. be able to.
因に、上記実施例では空気−酸素混合ガスの場合につい
て述べたが、他の笑気ガス（Ｎ２０）−酸素等の混合ガ
スにおいても本発明を何ら変更するものではない。Incidentally, in the above embodiment, the case of an air-oxygen mixed gas was described, but the present invention is not modified in any way even if other mixed gases such as laughing gas (N20)-oxygen are used.
