ところで、例えば不妊治療のため人工授精を行う場合、デッシュに卵子と精子の両方を入れて、このデッシュを顕微鏡観察用加温装置に載置した状態で顕微鏡観察しながら操作を行う。この操作には、1500倍の倍率で観察しながら良好な精子を選択し、次いで400倍の倍率で観察しながら選択した精子を卵子に注入する作業が含まれる。
上記したように液浸を用いる場合には、特許文献2の穴あきの顕微鏡観察用加温装置を使用することになるが、温度管理を高い精度で行う必要のある人工授精においては特許文献1の透明な加温プレートの顕微鏡観察用加温装置を使用してデッシュ内の卵子と精子を直接加温することが望ましい。
By the way, when artificial insemination is performed for infertility treatment, for example, both an ovum and sperm are put in the dish, and the operation is performed while observing the dish in a state where the dish is placed on a heating device for microscope observation.

As shown in FIG. 4, the microscope observation heating apparatus 1 is used by fitting the convex portion 4 into the opening K of the electric stage S and installing the outer frame 3 on the edge of the opening K of the electric stage S.
In the state shown in FIG. 4, the round hole 9 of the perforated warming plate portion 5 faces the position P where the objective lens T1 (or T2) used for observation is located.
The nichrome wire 13 of the perforated warming plate portion 5 is energized via the lead wire, and the transparent conductive film 23 of the transparent warming plate portion 7 is energized via the lead wire and electrode. Thereby, the nichrome wire 13 and the transparent conductive film 23 generate heat, and the perforated warming plate portion 5 and the transparent warming plate portion 7 are heated.

穴開き加温プレート部5、透明加温プレート部7の温度が温度センサ15、27によってそれぞれ検知され、この検知結果に基づきコントローラによってニクロム線13、透明導電膜23に対する通電が制御されて、板材11、12と下側ガラス21、上側ガラス22が所定の温度に保たれる。   The temperatures of the perforated warming plate portion 5 and the transparent warming plate portion 7 are detected by the temperature sensors 15 and 27, respectively, and the energization of the nichrome wire 13 and the transparent conductive film 23 is controlled by the controller based on the detection results, and the plate material 11, 12 and the lower glass 21 and the upper glass 22 are kept at a predetermined temperature.

図3、図4に示すようにデッシュDには養液Yが収容され、養液Y中に試料としての精子Hと卵子Eが入れられている。このデッシュDは穴開き加温プレート部5の中央部に載置して、デッシュDの中央部が丸穴9に対応するように備えられる。
そして、1500倍観察用の対物レンズT1に液浸用液を滴下してから、対物レンズT1を丸穴9へ進入させ、デッシュDの底部の下に移動させる。次いで液浸を用い1500倍の倍率で観察しながら、器具を用いて良好な精子Hを選択する。
As shown in FIG. 3 and FIG. 4, the nutrient solution Y is stored in the dish D, and the sperm H and the egg E as samples are placed in the nutrient solution Y. The dish D is placed on the center of the perforated warming plate part 5 so that the center of the dish D corresponds to the round hole 9.
Then, after the immersion liquid is dropped on the objective lens T1 for 1500 times observation, the objective lens T1 is moved into the round hole 9 and moved below the bottom of the dish D. Next, while observing at a magnification of 1500 times using immersion, good sperm H is selected using an instrument.

次に図示しない顕微鏡のレボルバを回動させて、図5に示すように対物レンズT1をポジションPから退避させ、電動ステージSを図4に示した位置からR方向へ駆動させて、透明加温プレート部7の中央部がポジションPにくる位置で停止させる。

6 and 7, the dish D on the perforated warming plate portion 5 indicated by the phantom line is moved to the central portion of the transparent warming plate portion 7 as indicated by the solid line. At this time, the dish D is slid and moved in the L direction on the perforated warming plate portion 5 and the transparent warming plate portion 7.
As described above, the upper surface of the perforated warming plate portion 5 and the upper surface of the transparent warming plate portion 7 are provided on the same plane, and there is no stepped portion. It is possible to slide smoothly on the upper surface of the transparent warming plate portion 7, and the dish D can be quickly provided in the central portion of the transparent warming plate portion 7. Since the dish D can be slid and moved without being lifted in this way, vibration applied to the dish D can be minimized, and adverse effects on the sperm H and the egg E can be prevented. .

次いで400倍の倍率で観察しながら、選択した精子Hを卵子Eに注入する作業を行う。透明加温プレート部7上のデッシュDは、その底部が透明加温プレート部7に接触しているので、精子H、卵子Eを直接加温でき、精度の高い温度管理が可能となる。   Next, the work of injecting the selected sperm H into the egg E is performed while observing at a magnification of 400 times. Since the bottom of the dish D on the transparent heating plate section 7 is in contact with the transparent heating plate section 7, the sperm H and the egg E can be directly heated, and highly accurate temperature management is possible.
