本発明はキャスター等の移動手段により移動可能な担架
装置に係り、特に担架に載置した荷重を支持する部分に
対してロードセル型の秤量装置を設置した担架に関する
。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a stretcher device that is movable by means of moving means such as casters, and particularly to a load cell type weighing device for a portion that supports a load placed on the stretcher. Regarding the stretcher with which it was installed.
通常、人の体重は、体重測定すべき人が秤量装置に立っ
た状態で乗ることにより測定するが、直立することが困
難な身体障害者や高齢者等はこのような状態で体重測定
することは困難若しくは不可能である。このため、例え
ば所謂寝たきり老人等の体重測定には、被測定者を特殊
な吊り下げ具により寝たままの状態で吊り下げて測定す
る等の方法が採用されている。Normally, a person's weight is measured by having the person whose weight is to be measured stand on a weighing device, but people with physical disabilities or elderly people who have difficulty standing upright may have their weight measured in this manner. is difficult or impossible. For this reason, for example, to measure the weight of a so-called bedridden elderly person, a method is adopted in which the person to be measured is suspended in a sleeping state using a special hanging device.
先ず、上述した吊り下げ方式は、測定の際に多くの人手
が必要であり、さらに被測定者にはかなりの苦痛を与え
ることになる。このためシイうな吊り下げ方式に代わり
、キャスタ等の移動手段が付いた担架装置（以下「スト
レッチャ」と称する）に体重測定手段を取りつけたもの
が提供されている。First, the above-mentioned hanging method requires a lot of manpower during measurement and also causes considerable pain to the person being measured. Therefore, instead of the hanging method, a stretcher device (hereinafter referred to as a "stretcher") equipped with moving means such as casters and a weight measuring means has been provided.
この装置は人が乗る担架の部分と、キャスタ等の移動手

僅かの人員で、しかも被測定者に苦痛を与えずに体重測
定を行うことができる。This device uses a mechanical weighing device using springs, etc., between the part of the stretcher on which the person sits and a frame with moving means such as casters, and measures the weight of the person while the person is lying down. is now possible. If you use this device,
To measure the weight of a person with a small number of personnel and without causing pain to the person being measured.
この装置は以上のような利点を有する反面、次のような
問題があり、その解決が望まれている。Although this device has the above-mentioned advantages, it also has the following problems, which need to be solved.
即ち、例えば急患の場合に、ストレッチャを救急車から

節作業を行なわねばならず、多大の手間を要することに
なる。That is, in the case of an emergency, for example, when the stretcher is pulled out of the ambulance or moved to the location where the patient is, it is unavoidable that the stretcher may be handled quite roughly, due to the nature of the device. However, when subjected to such handling, the mechanical adjustment of the mechanical weighing device described above is easily lost due to vibrations and shocks. For this reason, the reliability of the weighing device attached to the stretcher is inevitably low, and on the other hand, in order to maintain reliability, adjustment work must be performed frequently, which requires a great deal of effort.
本発明は上述した従来技術の問題点に鑑み構成したもの
であり、機械的秤量機構を廃して、ロードセル式秤量機
構を設置したストレッチャであることを特徴とする。The present invention has been constructed in view of the problems of the prior art described above, and is characterized in that it is a stretcher in which a mechanical weighing mechanism is eliminated and a load cell type weighing mechanism is installed.

A stretcher frame that supports loads such as a person's weight,
A load cell is arranged between the stretcher section on which the person is directly placed, and the body weight of the person is transmitted to the stretcher frame side via the load cell. As a result, the weight of the person is first applied to the load cell, so this added load (body weight)
is output electrically by a strain gauge, and the weight is displayed on a display device attached to the stretcher or installed separately. With this configuration, there are no mechanically operating parts, so it is less likely to go awry, and it is also far more accurate than mechanical systems.
以下本発明の実施例につき図面を参考に詳細に説明する

It is fixed at the four corners of the FIGS. 2 and 3 show the installed state of this load cell. Each load cell 8 is fixed to the upper support frame 4 of the stretcher frame 1 with a metal fitting 10. 14 is a strain gauge attached to the load cell body, which electrically outputs the deflection of the load cell body. Reference numeral 13 denotes a stopper screwed onto the lower part of the load cell main body, and when an excessive load is applied to the load cell, the lower end of the stopper comes into contact with the upper support frame 4, whereby the excessive load is supported by the upper support frame 4. , to prevent the load cell body from being damaged. Further, reference numeral 17 in FIG. 1 is an adder that adds up the electrical signals output from each load cell 8, and 18 is a display device that displays the weight of the subject based on the signal output from the adder 17. In addition to displaying the load, the display device 18 can also perform operations such as setting the zero point and adjusting the four corners. In addition, in the illustrated configuration, the display device 18 is attached to the stretcher frame 1, but this display device is installed separately from the stretcher, and when measuring weight, a connector is used to connect the load cell side and this separately installed display device. It may also be configured to be connected to a display device. If it is a separate device, it can be a large device with a built-in printer or the like.

That is, the stretcher section 9 is simply placed on the stretcher frame 1 via the load cell 8, and can be easily attached to and detached from the stretcher frame 1.

る構造となっていればよい。The stretcher section 9 is locked by stoppers 12 formed on each of the stretcher section and the upper support frame 4 (see FIG. 1). In addition to the structure in which the stretcher section 9 is placed directly on the load cell, there are also structures in which the frame of the stretcher section 9 is used as a support frame and a stretcher section 16 of a different configuration is further placed on this frame (see Fig. 3). However, in short, it is sufficient if the structure is such that the load on the stretcher side is transmitted to the stretcher frame side via the load cell.

、表示値！１Ｂに出力される。In the apparatus having the above configuration, first, the load of the stretcher section 9 itself is applied to each load cell 8, so the zero point of the weighing mechanism is set in this state. Next, by rotating the handle 7 and adjusting the elevating mechanism, the height of the bed on which the person M is sleeping is made equal to the height of the stretcher section 9, and then the person M is placed on the stretcher section 9. The weight of the person to be measured placed on the stretcher section 9 is supported by the stretcher frame 1 via each load cell 8, so the load cell 8 outputs an electrical signal corresponding to the weight of the person to be measured, and each of these load cells The output signals from are added in an adder 17 to obtain the displayed value! Output to 1B.
表示装置１８ではこの信号に基づき被測定者の体重が表
示される。The display device 18 displays the weight of the person to be measured based on this signal.
本発明は以上に示したように、ストレッチャフとなって
いるため、複雑な機械的秤量機構がなく、このためスト
レッチャを手荒に扱っても秤量機構に故障が発生する可
能性が少なく、また被測定者に苦痛を与えることなく常
時高精度の体重測定を行うことができる。As described above, since the present invention is a stretcher, there is no complicated mechanical weighing mechanism, so even if the stretcher is handled roughly, there is less possibility of failure in the weighing mechanism. Highly accurate weight measurement can be performed at all times without causing pain to the person taking the measurement.
