る。 A liquid-permeable cage 8 containing biological tissue pieces is inserted into the processing tank 4 . The processing tank 4 is equipped with an airtight lid 9, and the upper part of the processing tank 4 is connected to a pipe 10 through a three-way valve 11, a pipe 12 to a vacuum pump 13, or a pipe 1.
4 and selectively communicates with the atmosphere.
この様な一槽式包埋装置により、生物組織片の
包埋処理を行なう場合には、先ず、三方弁１１を
切り換える事により、処理槽４内を真空ポンプ１
３に通じさせ、この処理槽４内を減圧する。 When embedding biological tissue pieces using such a one-tank embedding device, first, by switching the three-way valve 11, the inside of the processing tank 4 is controlled by the vacuum pump 1.
3, and the pressure inside this processing tank 4 is reduced.
この結果、ロータリ弁１により管７と連通する
管５の一つを通り、管５に挿入された薬液タンク
２a1の薬液が処理槽４に吸込まれて、篭８を浸漬
し、篭８内の生物組織片を処理する。 As a result, the chemical liquid in the chemical liquid tank 2a1 inserted into the pipe 5 passes through one of the pipes 5 communicating with the pipe 7 by the rotary valve 1, is sucked into the processing tank 4, immerses the basket 8, and enters the inside of the basket 8. processing biological tissue pieces.

It is also possible to push it back into the tank. In this case, the processing tank 4 can be provided at a lower position than the tanks 2a, 2b, and 3.
ところで、上述の様に構成され作用する一槽式
包埋装置に於いて、処理槽４に薬液を供給する為
の薬液タンク２ａ，２ｂには、総て異なる種類の
薬液を貯溜しておくのではない。 By the way, in the one-tank embedding apparatus constructed and operated as described above, the chemical liquid tanks 2a and 2b for supplying the chemical liquid to the processing tank 4 store different types of chemical liquids. isn't it.
例えば、包埋装置の初期行程時に、処理槽４内

れも脱水、脱脂用のアルコールを貯溜しておき、
次の行程に於いて処理槽４内に薬液を供給する薬
液タンク２b1〜２b3には、処理槽内洗滌用のキシ
レンを貯溜しておく。 For example, during the initial process of the embedding device, alcohol for dehydration and degreasing is stored in the chemical liquid tanks 2a 1 to 2a 7 that supply the chemical liquid to the processing tank 4.
Xylene for cleaning the inside of the processing tank is stored in the chemical tanks 2b 1 to 2b 3 that supply the chemical into the processing tank 4 in the next step.

最後尾の薬液タンク２a7に、最も純度の高い無水
アルコールが貯溜される。 Among the chemical liquid tanks 2a 1 to 2a 7 that store alcohol, which is the same chemical liquid, the alcohol stored in the chemical liquid tank 2a 1 that communicates with the inside of the processing tank 4 first has the lowest purity, 2a 2 , 2a to 3 , the purity gradually increases, and in the chemical tank 2a storing alcohol, it is finally communicated with the processing tank 4.
Anhydrous alcohol of the highest purity is stored in the last chemical tank 2a7 .

に、次第に純度の高くなる複数（通常は図示の例
の様に７個）の薬液タンク２a1〜２a7から、順次
処理槽４にアルコールを給排する。 This is because when the alcohol in each chemical solution tank 2a 1 to 2a 7 is sent into the processing tank 4 and the biological tissue pieces in this processing tank 4 are processed, the water and fat in the tissue pieces mix into the alcohol. Therefore, in order to ensure complete dehydration and degreasing in the embedding device, chemical solutions are sequentially added from multiple (usually seven as in the illustrated example) tanks 2a 1 to 2a 7 of increasing purity. Alcohol is supplied to and discharged from the processing tank 4.
薬液タンク２b1〜２b3に貯溜されたキシレン
も、同様に、最初に処理槽４に連通される薬液タ
ンク２b1内のものが最も純度が低く、キシレンを
貯溜した薬液タンク２ｂの中では最後に処理槽４
に連通される、最後尾の薬液タンク２b3内のもの
が、最も純度が高くなつている。 Regarding the xylene stored in the chemical liquid tanks 2b 1 to 2b 3 , the purity of the chemical liquid tank 2b 1 that is first communicated with the processing tank 4 is the lowest, and the lowest purity of the chemical liquid tank 2b that stores xylene. processing tank 4
The chemical liquid in the last chemical liquid tank 2b3, which is communicated with the chemical liquid tank 2b3 , has the highest purity.
この様に各薬液タンク２ａ，２ｂ内に貯溜され
た薬液は、包埋処理を繰り返し行なう事により次
第に純度が低下し、良好な包埋処理を行なえなく
なる為、或る程度処理作業を行なつた後は、薬液
を入れ換えなければならない。 As described above, the purity of the chemical liquid stored in each chemical liquid tank 2a, 2b gradually decreases as the embedding process is repeated, making it impossible to perform a good embedding process. After that, you have to replace the chemical solution.
この際、全部の薬液を新しいものと交換したの
では、薬液が無駄となり、費用が嵩む為、例えば
アルコールを貯溜した薬液タンク２ａの場合、最

ルを貯溜したタンクを装着する様にしている。キ
シレンを貯溜したタンク２ｂの場合も同様であ
る。 At this time, replacing all the chemical solutions with new ones would waste the chemical solutions and increase costs. For example, in the case of the chemical solution tank 2a that stores alcohol, only the alcohol in the tank 2a 1 , which has the lowest purity, should be discarded. After that, move the chemical solution tank 2a 2 containing alcohol with a slightly higher purity to the tank 2a 1 position, and in the same way, move the tank 2a 7 to the tank 2a 6 position, and place a new anhydrous liquid in the tank 2a 7 position. It is equipped with a tank that stores alcohol. The same applies to the tank 2b storing xylene.
ところが、従来は総ての薬液タンク２ａ，２ｂ

化する事になり好ましくない。 However, conventionally, all chemical liquid tanks 2a, 2b
The work of replacing the chemical solution was troublesome, as it involved removing the chemical solution and transferring it one by one to the adjacent one. In particular, since the tubes 5, 5 are inserted deep into each chemical solution tank 2a, 2b, the work of extracting these tubes 5, 5 from each drug solution tank 2a, 2b is difficult if the embedding device is installed in a narrow space. It is difficult to do so if the chemical solution remaining in the pipe 5 drips and stains the clothes of the worker, or if the chemical solution is chloroform or the like, it spills on the floor and gives off a strange odor, worsening the surrounding environment. I don't like it because I have to do it.

注入する。(Structure of the present invention) In the method for exchanging chemical solutions in the single-tank embedding device of the present invention, among a plurality of chemical solution tanks storing the same type of drug solution, the one that communicates with the processing tank first during the embedding process is After discarding the chemical solution in the first chemical tank storing the lowest purity chemical solution, the slightly higher purity chemical solution stored in the adjacent second chemical tank is transferred to the processing tank, and then the above-mentioned multiple By switching the valve installed in the middle of the pipe connecting the chemical tank and the processing tank, the chemical liquid in the processing tank is transferred to the empty first chemical tank, and then transferred to the empty second chemical tank. By repeating the same operation to transfer a slightly higher purity chemical from an adjacent third chemical tank into the tank, one of the plurality of chemical liquid tanks storing the same type of chemical liquid was packaged. After the last chemical liquid tank that communicates with the processing tank is finally emptied during burial treatment, a new chemical liquid is injected into this last chemical liquid tank.
（実施例）
次に、図示の一槽式包埋装置を参照しつつ本発
明を更に詳しく説明する。(Example) Next, the present invention will be described in more detail with reference to the illustrated one-tank embedding apparatus.
薬液の入れ換えを行なう場合には、先ず、同一

ａ，２ｂの内、包埋処理時に最初に処理槽４に連
通する、それぞれ最も純度の低いアルコール、キ
シレンを貯溜した薬液タンク２a1，２b1を外し、
内部のアルコール、キシレンを廃棄する。 When replacing the chemical solution, first, the chemical solution tanks 2 each containing the same type of chemical solution are replaced.
Of a and 2b, remove the chemical tanks 2a 1 and 2b 1 , which store the lowest purity alcohol and xylene, respectively, and which communicate with the processing tank 4 first during the embedding process.
Discard the alcohol and xylene inside.
次いで、ロータリ弁１が薬液タンク２a1と処理
槽４とを通過させた状態で、真空ポンプ１３を運
転する。タンク２a1は空である為、管５から処理

より、タンク２a1内が空である事が確かめられ
る。 Next, the vacuum pump 13 is operated with the rotary valve 1 allowing the chemical solution tank 2a 1 and the processing tank 4 to pass through. Since the tank 2a1 is empty, air freely flows into the processing tank 4 from the pipe 5, and the pressure inside the processing tank 4 does not decrease. Therefore, if a pressure switch is installed at an appropriate location, the vacuum pump 13 can be turned on. By operating for a certain period of time, it can be confirmed that the tank 2a1 is empty.
タンク２a1に薬液が残つていると、次の操作で
タンク２a2の薬液をタンク２a1に移す事が出来な
い（溢れる）為、警報により注意を促す。タンク
２a1が空である事を確認出来たならば、ロータリ
弁１を切り換えて、タンク２a2を処理槽４に通じ
させ、真空ポンプ１３を駆動して、このタンク２
a2内のアルコールを処理槽４内に吸引する。 If the chemical solution remains in the tank 2a 1 , the chemical solution in the tank 2a 2 cannot be transferred to the tank 2a 1 in the next operation (overflow), so an alarm is issued to call for attention. After confirming that the tank 2a 1 is empty, switch the rotary valve 1 to make the tank 2a 2 communicate with the processing tank 4, drive the vacuum pump 13, and drain the tank 2.
The alcohol in a 2 is sucked into the processing tank 4.
タンク２a2内のアルコールを総て処理槽４内に
吸引したならば、ロータリ弁１を切り換えて再び
タンク２a1の処理槽４とを通じさせると共に、三
方弁１１を切り換えて管１０と管１４とを連通さ

に移し換える。 Once all the alcohol in the tank 2a 2 has been sucked into the processing tank 4, switch the rotary valve 1 to make the tank 2a 1 communicate with the processing tank 4 again, and switch the three-way valve 11 to connect the pipe 10 and the pipe 14. The alcohol in the processing tank 4 is transferred to the tank 2a1 .
この操作により、タンク２a2が空になるので、
次いでタンク２a2のアルコールをタンク２a1に移
したのと同様の手順で、タンク２a3内のアルコー
ルをタンク２a2に移し換え、以下同様の作業を繰
り返し行なつて、タンク２a7内のアルコールをタ
ンク２a6に移し換える。 This operation empties tank 2a 2 , so
Next, in the same manner as the alcohol in tank 2a 2 was transferred to tank 2a 1 , the alcohol in tank 2a 3 is transferred to tank 2a 2 , and the same process is repeated to remove the alcohol in tank 2a 7 . Transfer to tank 2a 6 .
タンク２a7内のアルコールをタンク２a6に移し
換え、このタンク２a7と隣りのタンク２b1とが空
である事を確認したならば、前記したアルコール
の場合と同様にして、タンク２b2内のキシレンを
タンク２b1内に移し換え、次いでタンク２b3内の
キシレンをタンク２b2内に移し換える。 After transferring the alcohol in tank 2a 7 to tank 2a 6 and confirming that this tank 2a 7 and the adjacent tank 2b 1 are empty, transfer the alcohol in tank 2b 2 in the same manner as in the case of alcohol described above. xylene in tank 2b 1 is transferred, and then xylene in tank 2b 3 is transferred into tank 2b 2 .
以上の操作が完了した時点で、アルコール、キ
シレンは、それぞれ１個ずつ前のタンクに移し換

注入して、薬液の入れ換え作業を完了する。 When the above operations are completed, alcohol and xylene are transferred one by one to the previous tank, and the last tanks 2a 7 and 2b 3 are empty, so new anhydrous alcohol is placed in tank 2a 7 . Pure xylene is injected into tanks 2b and 3 , respectively, to complete the chemical replacement work.
以上の操作の内、タンク２a1，２b1の薬液廃棄

来る。 Furthermore, when injecting a new chemical solution into the tanks 2a 7 and 2b 3 , if the chemical solution injected into the processing tank 4 is transferred to each tank 2a 7 and 2b 3 through the pipe 7, rotary valve 1, and pipe 5, the tank 2a 7 and 2b 3 are no longer required. However, in this case, in order to prevent xylene from being mixed with the absolute alcohol injected into tank 2a 7 , the alcohol in tank 2a is transferred to tank 2a 6 , and tank 2a 7 is Once the tank 2b is empty, pour absolute alcohol into the treatment tank 4 before transferring the xylene from the tank 2b, and pour this absolute alcohol into the tank 2.
Transfer to a 7 . This operation can also be performed automatically according to the microcomputer program if the replenishment tank containing absolute alcohol for replenishment is connected to the rotary valve through a pipe. tank 2b 3
Injection of pure xylene into can be performed in a similar manner.
