Description

【０００１】
【発明の属する技術分野】
本発明は、生体組織などの検査のために試料ブロックを薄切りして検査用等の薄片を作製する試料薄切装置などにおいて、試料ブロックを加湿するために使用される加湿装置に係る。
【０００２】
【従来の技術】
理科学試料の分析や生体試料の顕微鏡観察などの際、検体をパラフィン等の包埋材に埋め込み、これをミクロト−ムなどの試料薄切装置を用いて薄く切断して、検査用等の薄片が作製される。
【０００３】
切断の際、試料ブロックの表面が乾燥していると切断面に疵や変形が生ずるので、試料ブロックの表面が乾燥しないように、その周囲の湿度を調整しておく必要がある。なお、試料ブロックの周囲の湿度に関しては、比較的高め（８５相対％以上）である方がうまく薄切りができることが知られている。このため、薄切り用のナイフに隣接して加湿装置を設置し、水を霧状に噴霧することにより試料ブロックの周囲の加湿を行っている。
【０００４】
（従来の加湿装置の問題点）
加湿装置としては、タンク内に貯えられた水を加熱して蒸気を発生させ、この蒸気をミスト状にして噴射する方式が一般的である。しかし、試料ブロックの周囲にミスト（霧状の混合流体）を噴射して加湿する際、ミストの温度が変化すると、試料ブロックの温度も変化する。その結果、試料ブロックが膨張または収縮し、設定した目標厚さと実際に切り取られた薄片の厚さの間に誤差が生ずる。
【０００５】
このため、試料薄切装置の加湿装置には、上記方式による加湿装置は適さず、それに代わって超音波振動式の加湿装置が使用されている。しかし、超音波振動式の加湿装置であっても、タンク内に貯えられている水の温度が上昇してしまい、結果として上記と同様な不具合が生じることがある。
【０００６】
【発明が解決しようとする課題】
本発明は、以上のような従来の試料薄切装置における加湿装置の問題点に鑑み成されたもので、本発明は、切り取られた薄片の厚さを正確に目標値に一致させることができる加湿装置を提供することにある。
【０００７】
【課題を解決するための手段】
本発明の加湿装置は、
水を貯えるタンクと、
タンク内の水に超音波振動を与えてミストを発生させる超音波振動子と、
発生したミストをタンクの外に噴射するノズルと、
タンク内の水の温度を検出する温度検出器と、
この温度検出器の出力に基づいてタンク内の水の温度を目標温度に調整する温度制御装置と、
を備えたことを特徴とする。
【０００８】
本発明の加湿装置によれば、ミスト（霧状の混合流体）を発生させる超音波振動子に加えて、タンク内の水の温度を目標温度に調整する温度制御装置を備えているので、ノズルから噴射されるミストの温度を一定に維持することができる。
【０００９】
また、本発明の試料薄切装置用の加湿装置は、
試料ブロックを薄切りして薄片を作製する試料薄切装置において試料ブロックを加湿するために使用される加湿装置であって、
水を貯えるタンクと、
タンク内の水に超音波振動を与えてミストを発生させる超音波振動子と、
発生したミストを前記試料ブロックの周囲に噴射するノズルと、
タンク内の水の温度を検出する温度検出器と、
この温度検出器の出力に基づいてタンク内の水の温度を目標温度に調整する温度制御装置と、
を備えたことを特徴とする。
【００１０】
本発明の試料薄切装置用の加湿装置によれば、ミストを発生させる超音波振動子に加えて、タンク内の水の温度を目標温度に調整する温度制御装置を備えているので、試料ブロックの周囲に供給されるミストの温度を一定に維持することができる。これにより、試料ブロックの温度を一定に保ち、その結果として、切り取られた薄片の厚さを正確に目標値に一致させることができる。
【００１１】
好ましくは、上記の温度制御装置は、超音波振動子によるタンク内の水の温度上昇を抑える手段として、投げ込み式クーラを備える。
【００１２】
なお、上記の加湿装置において、タンク内の水の温度を検出する代わりに、ノズルから噴射されたミストの温度を検出し、その値に基づいてタンク内の水の温度を制御してミストの温度を目標温度に調整してもよい。
【００１３】
【発明の実施の形態】
図１に、本発明の試料薄切装置用の加湿装置の概略構成を示す。図中、１はタンク、２は超音波振動子、４は温度センサ、５は投げ込み式クーラ、６は温度制御装置、７はノズル、１０は試料ブロック、１１は薄切り用のナイフを表す。
【００１４】
タンク１の中には水が貯えられている。タンク１の中には超音波振動子２が組み込まれ、超音波振動子２の起動及び停止は制御装置３によって制御される。タンク１の中には、更に、温度センサ４及び投げ込み式クーラ５が配置されている。温度センサ４の出力は温度制御装置６に送られ、温度制御装置６は投げ込み式クーラ５の出力を制御して、タンク１内の水の温度を設定された目標温度に維持する。超音波振動子２を起動すると、タンク１内でミスト９が発生し、ノズル７を通って試料ブロック１０の周囲に供給される。
【００１５】
なお、上記の例では、タンク１内の温度を測定し、タンク１内の温度が所定の温度になるように投げ込み式クーラ５を制御しているが、それに代わって、ノズル７から噴射されるミスト９の温度を測定し、ミスト９の温度が所定の温度になるように投げ込み式クーラ５を制御してもよい。
【００１６】
【発明の効果】
本発明の加湿装置によれば、ノズルから噴射されるミストの温度を一定に保つことができる。また、本発明の加湿装置を試料薄切装置において使用すれば、試料ブロックの周囲に供給されるミストの温度を一定にすることによって、試料ブロックの温度が一定に保たれ、その結果として、切り取られた薄片の厚さを正確に目標値に一致させることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a humidifying device used for humidifying a sample block in a sample slicing device or the like for slicing a sample block for inspection of a living tissue or the like to produce a slice for an inspection or the like.
[0002]
[Prior art]
When analyzing a scientific sample or observing a biological sample under a microscope, the sample is embedded in an embedding material such as paraffin, and this is thinly cut using a sample slicing device such as a microtome, and is used for thin sections for inspection and the like. Is produced.
[0003]
At the time of cutting, if the surface of the sample block is dry, the cut surface may be flawed or deformed. Therefore, it is necessary to adjust the surrounding humidity so that the surface of the sample block does not dry. It is known that thinner slices can be formed more effectively when the humidity around the sample block is relatively high (85 relative% or more). For this reason, a humidifier is installed adjacent to the slicing knife, and water is sprayed in mist to humidify the periphery of the sample block.
[0004]
(Problems with conventional humidifiers)
As a humidifier, a method is generally used in which water stored in a tank is heated to generate steam, and the steam is sprayed in a mist state. However, when a mist (mist-like mixed fluid) is sprayed and humidified around the sample block and the mist temperature changes, the temperature of the sample block also changes. As a result, the sample block expands or contracts, causing an error between the set target thickness and the thickness of the actually cut slice.
[0005]
For this reason, the humidifier of the above-mentioned method is not suitable for the humidifier of the sample slicing apparatus, and an ultrasonic vibration type humidifier is used instead. However, even with the ultrasonic vibration type humidifier, the temperature of the water stored in the tank rises, and as a result, the same problem as described above may occur.
[0006]
[Problems to be solved by the invention]
The present invention has been made in view of the problems of the humidifying device in the conventional sample slicing apparatus as described above, and the present invention can accurately match the thickness of the cut slice to a target value. It is to provide a humidifying device.

It is characterized by having.
[0008]
According to the humidifier of the present invention, the nozzle is provided with the temperature control device for adjusting the temperature of the water in the tank to the target temperature, in addition to the ultrasonic vibrator for generating the mist (mist-like mixed fluid).

It is characterized by having.
[0010]
According to the humidifying device for a sample slicing device of the present invention, in addition to the ultrasonic vibrator for generating mist, the temperature control device for adjusting the temperature of the water in the tank to the target temperature is provided. The temperature of the mist supplied to the surrounding area can be kept constant. As a result, the temperature of the sample block can be kept constant, and as a result, the thickness of the sliced slice can be accurately matched with the target value.
[0011]
Preferably, the temperature control device includes a throw-in cooler as means for suppressing a rise in the temperature of water in the tank due to the ultrasonic vibrator.
[0012]
In the above humidifier, instead of detecting the temperature of the water in the tank, the temperature of the mist sprayed from the nozzle is detected, and the temperature of the water in the tank is controlled based on the detected value. May be adjusted to the target temperature.

[0014]
Water is stored in the tank 1. An ultrasonic oscillator 2 is incorporated in the tank 1, and the start and stop of the ultrasonic oscillator 2 are controlled by a control device 3. In the tank 1, a temperature sensor 4 and a throw-in cooler 5 are further arranged.
