Description

本発明は、可撓性合成樹脂製シートを成型し製袋した血液バッグに貯蔵された凍結血漿を解凍する凍結血漿解凍装置に関する。 The present invention relates to a frozen plasma thawing apparatus for thawing frozen plasma stored in a blood bag formed by molding a flexible synthetic resin sheet.

従来より、一般病棟やＩＣＵ、ＣＣＵ、透析室などの特殊病棟において、血液バッグに貯蔵された凍結血漿の解凍は、通常は凍結血漿バッグを恒温水槽に浸漬して、場合によっては温水を入れた洗面器に浸漬して行われている。しかしながら、このような温水を用いた解凍方法は衛生的でないという問題がある。 Conventionally, in general wards and special wards such as ICU, CCU, and dialysis room, thawing of frozen plasma stored in a blood bag is usually performed by immersing the frozen plasma bag in a constant temperature water bath, and in some cases adding hot water It is performed by immersing it in a washbasin. However, there is a problem that such a thawing method using warm water is not hygienic.

そこで、温水を使用することなく、安全かつ衛生的に血液バッグに貯蔵された凍結血漿を解凍する凍結血漿解凍装置の開発が求められてきた。この求めに応じて、特開２００１−２１８８１７号公報（特許文献１）に開示された凍結血漿解凍装置が提案された。 Therefore, there has been a demand for the development of a frozen plasma thawing apparatus that thaws frozen plasma stored in a blood bag safely and hygienically without using hot water. In response to this request, a frozen plasma thawing device disclosed in Japanese Patent Laid-Open No. 2001-218817 (Patent Document 1) has been proposed.

この従来の凍結血漿解凍装置は、対峙する両壁面に多数の温風吹出ノズルが形成された解凍室に隣接して温風供給チャンバを形成し、この温風供給チャンバへの温風流入部にエアフィルタを配設するとともに、前記温風供給チャンバの外側に前記エアフィルタ面に向けて温風を吹き付ける温風発生装置を配設し、前記解凍室と前記温風発生装置の配設空間とを温風循環路によって連通したことを特徴としたものである。 In this conventional frozen plasma thawing apparatus, a hot air supply chamber is formed adjacent to a thawing chamber in which a large number of hot air blowing nozzles are formed on opposite wall surfaces, and air is supplied to the hot air inflow portion into the hot air supply chamber. A filter is disposed, and a warm air generator for blowing warm air toward the air filter surface is disposed outside the warm air supply chamber, and the thawing chamber and a space for arranging the warm air generator are provided. It is characterized by communication through a hot air circulation path.

凍結血漿が貯蔵された凍結血漿バッグは複数個が吊持設備によって吊り状態で前記解凍室に収容され、概ね４０ｍ／ｓ以上の温風を吹き付けられる。これによって、上記の凍結血漿解凍装置は、複数の凍結血漿バッグを従来の浸漬方法の場合と同等の約３０分の解凍時間を達成しているようである。 A plurality of frozen plasma bags in which frozen plasma is stored are accommodated in the thawing chamber in a suspended state by a suspension device, and hot air of approximately 40 m / s or more is blown. Thus, the above-mentioned frozen plasma thawing apparatus seems to achieve a thawing time of about 30 minutes, which is equivalent to that in the case of a conventional dipping method for a plurality of frozen plasma bags.

しかしながら、この従来の凍結血漿解凍装置は恒温水槽よりも大型で価格も高いという問題がある。しかも、送風機と高性能エアフィルタが発生する騒音を防音材で遮音しなければならないという問題もある。
特開２００１−２１８８１７号公報 However, this conventional frozen plasma thawing apparatus has a problem that it is larger and more expensive than a constant temperature water tank. In addition, there is a problem that noise generated by the blower and the high-performance air filter must be sound-insulated with a soundproofing material.

The regulator 21 is also connected to the timer 22 in the control device 20.

また、前記凍結血漿解凍用ケースを揺動させる揺動手段は、図１及び図３に示す如く、前記凍結血漿解凍用ケースを揺動可能に支持する回転支軸と、前記凍結血漿解凍用ケースを揺動させる揺動機構３０とで構成されている。揺動機構３０は、制御装置２０のタイマー２２により作動時間が設定されたモータ２６で駆動される。前記作動時間は解凍予定時間であり、７分から１５分の間で、解凍対象と環境及び設定温度を考慮して定められる適切な時間である。   Further, the swinging means for swinging the frozen plasma thawing case includes, as shown in FIGS. 1 and 3, a rotating support shaft that swingably supports the frozen plasma thawing case, and the frozen plasma thawing case. And a rocking mechanism 30 that rocks. The swing mechanism 30 is driven by a motor 26 whose operation time is set by the timer 22 of the control device 20. The operation time is a scheduled thawing time, and is an appropriate time determined in consideration of the thawing target, the environment, and the set temperature between 7 and 15 minutes.

即ち、前記回転支軸は、第１ヒータ支持板６と規制板７を介してケース本体１１の中心部に固着されたケース側支軸２７と、制御装置側支軸２８とをベアリング２９で回動可能にして結合したものである。   That is, the rotation support shaft rotates the case side support shaft 27 fixed to the center portion of the case body 11 via the first heater support plate 6 and the restriction plate 7 and the control device side support shaft 28 by the bearing 29. It is a combination that is movable.

また、揺動機構３０は一端を第１ヒータ支持板６と規制板７を介してケース本体１１の片側端部近くに固定された支持部材２４に回動可能に支持されたクランクアーム２３と、クランクアーム２３の他端が回動可能に支持されたカム２５とで構成されている。 The swing mechanism 30 has a crank arm 23 rotatably supported at one end by a support member 24 fixed near one end of the case body 11 via the first heater support plate 6 and the restriction plate 7; The other end of the crank arm 23 is composed of a cam 25 that is rotatably supported.

上述の如く構成された本発明に係る凍結血漿解凍装置を用いた凍結血漿の解凍は次のようにして行われる。先ず、利用者は凍結血漿解凍用ケースの取手１５を持って蓋１２を開け、図２に示す如く、ケース本体１１内の第１熱媒体バッグ２上に凍結血漿バッグ１を載置する。   The thawing of frozen plasma using the frozen plasma thawing apparatus according to the present invention configured as described above is performed as follows. First, the user holds the handle 15 of the frozen plasma thawing case, opens the lid 12, and places the frozen plasma bag 1 on the first heat medium bag 2 in the case body 11 as shown in FIG.

続いて、利用者が凍結血漿解凍用ケースの蓋１２を閉じ、図示しないロック機構で蓋１２をケース本体１１にロックすると、図１に示す如く、凍結血漿バッグ１は第１熱媒体バッグ２と第２熱媒体バッグ３との間に、弾性部材１４の作用を受けて適度の圧力で挟持される。   Subsequently, when the user closes the cover 12 of the frozen plasma thawing case and locks the cover 12 to the case body 11 with a lock mechanism (not shown), the frozen plasma bag 1 is connected to the first heat medium bag 2 as shown in FIG. Between the second heat medium bag 3, the elastic member 14 receives the action and is sandwiched with an appropriate pressure.

温度調節器２１の設定温度を設定し、更に解凍予定時間をタイマー２２に設定し、利用者が制御装置の図示しない起動スイッチを入れると、モータ２６は起動し、カム２５を回転させる。すると、カム２５はクランクアーム２３を駆動してケース本体１１と蓋１２からなる凍結血漿解凍用ケースを揺動させる。前記設定温度は、３５℃から３９℃の範囲で、解凍対象と環境を考慮して定められる適切な温度である。   When the set temperature of the temperature controller 21 is set, the estimated thawing time is set in the timer 22, and the user turns on a start switch (not shown) of the control device, the motor 26 is started and the cam 25 is rotated. Then, the cam 25 drives the crank arm 23 to swing the frozen plasma thawing case composed of the case body 11 and the lid 12. The set temperature is an appropriate temperature determined in consideration of the thawing target and the environment in the range of 35 ° C to 39 ° C.

すると、ケース本体１１と蓋１２からなる凍結血漿解凍用ケース内に張設されている第１熱媒体バッグ２と第２熱媒体バッグ３が揺動し、これら熱媒体バッグに貯留されている熱媒体がバッグ内で流動する。即ち、凍結血漿バッグ１によって冷やされた熱媒体と第１板状ヒータ４で加温された熱媒体が第１熱媒体バッグ２内で流動する。同時に、凍結血漿バッグ１によって冷やされた熱媒体と第２板状ヒータ５で加温された熱媒体が第２熱媒体バッグ２内で流動する。このような熱媒体の流動によって、凍結血漿バッグ１には第１板状ヒータ４と第２板状ヒータ５で両側からの熱が、熱媒体が流動しない場合に比較して効率的に伝達される。   Then, the first heat medium bag 2 and the second heat medium bag 3 stretched in the frozen plasma thawing case composed of the case main body 11 and the lid 12 are swung, and the heat stored in these heat medium bags. The medium flows in the bag. That is, the heat medium cooled by the frozen plasma bag 1 and the heat medium heated by the first plate heater 4 flow in the first heat medium bag 2. At the same time, the heat medium cooled by the frozen plasma bag 1 and the heat medium heated by the second plate heater 5 flow in the second heat medium bag 2. Due to such a flow of the heat medium, heat from both sides is transmitted to the frozen plasma bag 1 more efficiently by the first plate heater 4 and the second plate heater 5 than when the heat medium does not flow. The

タイマー２２に設定された時間が経過すると、モータ２６は停止し、ケース本体１１と蓋１２からなる凍結血漿解凍用ケースの揺動は停止する。また、タイマー２２に設定された時間が経過したときに、温度調節器２１は第１板状ヒータ４と第２板状ヒータ５への電力供給を停止する。そこで、利用者は蓋１２を開け、血漿が解凍された凍結血漿バッグ１をケース本体から取り出す。 When the time set in the timer 22 elapses, the motor 26 stops and the swinging of the frozen plasma thawing case composed of the case body 11 and the lid 12 stops. Further, when the time set in the timer 22 has elapsed, the temperature controller 21 stops supplying power to the first plate heater 4 and the second plate heater 5. Therefore, the user opens the lid 12 and takes out the frozen plasma bag 1 from which the plasma has been thawed from the case body.

以上詳細に説明した通り、本発明は、温度調節されたヒータで外側から加温されている熱媒体バッグによって凍結血漿バッグを包み込むようにして収容した凍結血漿解凍用ケースを揺動手段によって揺動させ、前記熱媒体バッグ内の熱媒体を流動させて前記ヒータから前記凍結血漿バッグへの効率的な熱伝達を実現したことを特徴とする凍結血漿解凍装置である。従って、本発明に係る凍結血漿解凍装置を用いたときの凍結血漿の解凍時間は７分から１５分となり、従来よりも大幅に短縮された。しかも、本発明に係る凍結血漿解凍装置は、構成が簡単で取り扱いが容易なコンパクトな装置である。 As described above in detail, the present invention swings the frozen plasma thawing case, which is housed so as to wrap the frozen plasma bag by the heat medium bag heated from the outside with a temperature-controlled heater by the swinging means. In the frozen plasma thawing apparatus, the heat medium in the heat medium bag is flowed to realize efficient heat transfer from the heater to the frozen plasma bag. Therefore, the thawing time of the frozen plasma when using the frozen plasma thawing apparatus according to the present invention was 7 minutes to 15 minutes, which was significantly shortened compared to the conventional case. Moreover, the frozen plasma thawing device according to the present invention is a compact device that has a simple configuration and is easy to handle.

なお、凍結血漿解凍用ケースは実施例ではケース本体１１と蓋１２からなるものとしたが、他の構造にすることも可能である。例えば、有底で矩形の蓋付ケースでも実現できる。また、可撓性合成樹脂製シートを成型し製袋したバッグに流動可能な熱媒体が貯留され密閉された熱媒体バッグは、実施例では第１熱媒体バッグ２と第２熱媒体バッグ３の一対のバッグで構成したが、これらを繋げた如き１個の熱媒体バッグであってもよい。   Although the frozen plasma thawing case is composed of the case body 11 and the lid 12 in the embodiment, other structures may be used. For example, a bottomed and rectangular case with a lid can be realized. Further, in the embodiment, the heat medium bag in which the heat medium that can flow is stored and sealed in the bag made by molding the flexible synthetic resin sheet is formed of the first heat medium bag 2 and the second heat medium bag 3. Although constituted by a pair of bags, it may be a single heat medium bag in which these bags are connected.
