この発明は凍結血液の解凍装置に係り、特に凍結血液塊
を支持材に載せて空気を当てながら解凍する凍結血液の
解凍装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application] The present invention relates to a thawing device for frozen blood, and more particularly to a thawing device for frozen blood in which a frozen blood clot is placed on a support material and thawed while being exposed to air.
血液から血漿（血液からヘモグロビンを除去した成分）
を抽出して薬品を製造する際、−投に凍結保存した袋詰

った袋をそのまま水槽の中に浸漬して行うが、袋が大き
く解凍に長時間を要する。Plasma from blood (component from which hemoglobin has been removed)
When extracting blood to produce drugs, bagged blood that has been frozen and stored is used. This thawing method involves immersing a bag containing frozen blood in a water tank, but the bag is large and takes a long time to thaw.
このため、凍結血液を破砕して、これを格子や網などの
支持材に載せてこれに空気を流して解凍する方法が考え
られる。しかし、この方法では融解した血液が流下する
際に支持材の表面に微量蛋白質であるクリオが析出し、
血液が流下する。クリオは次第に成長し、そのままでは
支持材の隙間を埋めてしまうことになる。この結果、血
液が流下しなくなることもあり、この解凍方法はこれま
で採用されていない。For this reason, a possible method is to crush frozen blood, place it on a support material such as a grid or net, and thaw it by flowing air through it. However, with this method, when the molten blood flows down, a trace amount of cryo protein is deposited on the surface of the support material.
Blood flows down. Clio will gradually grow, and if left as it is, it will fill the gap in the support material. As a result, blood may not flow down, so this thawing method has not been used to date.
クリオは低温で振動などの刺激を与えると析出する寒冷
沈殿物質で１０℃以上で溶けて品質が悪くなる。このた
め、この解凍においても１０℃以下の低温を保持しなけ
ればならない。Cryo is a cryoprecipitated substance that precipitates when exposed to vibrations or other stimuli at low temperatures, and melts at temperatures above 10°C, resulting in poor quality. Therefore, the temperature must be maintained at a low temperature of 10° C. or lower even during this thawing.
この発明の目的は前記従来技術の欠点を解消し、凍結血
液を積載する支持材の隙間にクリオが成長するのを防ぎ
、連続的に空気によって解凍することができる凍結血液
の解凍装置を提供するにある。An object of the present invention is to provide a thawing device for frozen blood that eliminates the drawbacks of the prior art, prevents cryo from growing in the gaps between supporting materials on which frozen blood is loaded, and allows continuous thawing with air. It is in.

たものである。In this invention, in order to prevent crevices from occurring during thawing of frozen blood using air and filling gaps in the support material loaded with frozen blood, this support material is constructed from a plurality of horizontal parallel bars. This rod is rotated around a horizontal axis to prevent chestnuts from adhering to and growing on the supporting material.

The water is discharged from the upper part of the tank 1 into the circulation duct 10B.

成長しない。The clitoris 14 precipitated from the concentrated blood adheres to the rotating rod 2, but as the rotating rod 2 rotates, the J blood supply area 7
The chestnut 14 does not grow on the rotary rod 2 because it is scraped off and falls.
このため血液は常に全面から均一に落下して安定した解

It is possible to perform stable defrosting without any problems.
