特開平１０−１９２３９８号公報JP-A-10-192398

図３は、従来の代表的なシリンジポンプ装置を示し、１０はシリンジベース、２０はシリンジベース１０上に載置されるシリンジで、シリンジベース１０に設けた溝１１と、シリンジ押え３０によりその外筒が保持される。また、２１は押し子、４０は押し子プッシャー（以下、単にプッシャーと称す）、４１は上記プッシャーに形成した鍔部、５０は上記プッシャー４０をその上面で摺動自在に保持し下面が開放された半円筒状パイプ、６４は上記シリンジベース１０に回転自在に支持された送りネジ、６５はこの送りねじ６４の下面に係合する送りナット、６６はこの送りナット６４と上記プッシャー４０の下端間を連結する連結具、６０は上記送りねじ６４をギヤ列６１〜６３を介して転回する駆動モータを示す。 FIG. 3 shows a conventional typical syringe pump device, where 10 is a syringe base, 20 is a syringe placed on the syringe base 10, and a groove 11 provided in the syringe base 10 and a syringe presser 30 are used to The cylinder is held. Further, 21 is a pusher, 40 is a pusher pusher (hereinafter simply referred to as a pusher), 41 is a flange formed on the pusher, 50 is a slidable holding of the pusher 40 on its upper surface, and the lower surface is opened. A semi-cylindrical pipe, 64 is a feed screw rotatably supported by the syringe base 10, 65 is a feed nut engaged with the lower surface of the feed screw 64, and 66 is between the feed nut 64 and the lower end of the pusher 40. Reference numeral 60 represents a drive motor for rotating the feed screw 64 via gear trains 61-63.

このようなシリンジポンプ装置では、制御装置７０と組合わせて、駆動モータ６０を回転させると、出力軸に接続されたギヤ列を介して、送りネジ６４が転回され、この送りネジ６４に噛み合う送りナット６５を介して、パイプ５０をガイドにしてプッシャー４０がリニアに移動し、シリンジ２０の押し子２１を押し、薬液が注入される。 In such a syringe pump device, when the drive motor 60 is rotated in combination with the control device 70, the feed screw 64 is rotated via the gear train connected to the output shaft, and the feed screw 64 meshes with the feed screw 64. The pusher 40 moves linearly through the nut 65 using the pipe 50 as a guide, pushes the pusher 21 of the syringe 20, and the chemical solution is injected.

尚、制御装置７０には、動作設定や各種設定を行う入力部７１、入力部７１の設定情報や各種センサ（図示せず）の情報に基づき実際に適時制御を行う制御部７２、状態や設定状況を表示する表示部７３、及び、注意や警告を促す警報器７４等が含まれており、これらの詳細機能及びその有無や配置位置等は適宜選択される。 The control device 70 includes an input unit 71 that performs operation settings and various settings, a control unit 72 that actually performs timely control based on setting information of the input unit 71 and information of various sensors (not shown), and states and settings. A display unit 73 for displaying the situation, an alarm device 74 for caution and warning, and the like. These detailed functions, presence / absence thereof, arrangement position, and the like are appropriately selected.

然し、特に血液透析装置に搭載される従来のシリンジポンプ装置では、シリンジの押し子２１がプッシャー４０の鍔部４１に正常に装着されていることを検出する手段を有していないものが主流であった。 However, in the conventional syringe pump device mounted on the hemodialysis apparatus, in particular, the one having no means for detecting that the pusher 21 of the syringe is normally attached to the collar 41 of the pusher 40 is mainstream. there were.

この為、シリンジの押し子２１が正常に装着されていなくても、プッシャー４０で押し子２１を押すことが出来る為、薬液が注入されてしまう。また、この状態でシリンジ２０内に陰圧が加わると、押し子２１がプッシャー４０の鍔部４１に嵌着していないのでプッシャー４０とは関係無しに押し子２１がシリンジ２０内に吸い込まれてしまい、薬液が過剰に注入されてしまう。 For this reason, even if the pusher 21 of the syringe is not normally mounted, the pusher 21 can be pushed by the pusher 40, so that a chemical solution is injected. Further, when a negative pressure is applied to the syringe 20 in this state, the pusher 21 is not inserted into the flange 41 of the pusher 40 and the pusher 21 is sucked into the syringe 20 regardless of the pusher 40. Therefore, the chemical solution is excessively injected.

また、シリンジの押し子２１がプッシャー４０の鍔部４１に正常に装着されていることを検出する手段を有しているシリンジポンプ装置でも、例えば、プッシャー４０内に、シリンジの押し子２１の装着状態によって信号状態が変化するようにマイクロスイッチやフォトインタラプタを付設し、これらの信号を、シリンジベース１０に設けたスリット孔や、別に設けた配線用の中空パイプを介してリード線（有線）で、シリンジベースの背面方向に設置された制御部７２と接続することで、押し子２１の装着状態を検出していた。   Further, even in a syringe pump device having means for detecting that the syringe pusher 21 is normally attached to the collar 41 of the pusher 40, for example, the syringe pusher 21 is attached in the pusher 40. Microswitches and photointerrupters are attached so that the signal state changes depending on the state, and these signals are sent by lead wires (wired) through slit holes provided in the syringe base 10 or separately provided wiring hollow pipes. The attachment state of the pusher 21 was detected by connecting with the control part 72 installed in the back direction of the syringe base.

然しながら、上述のような従来技術に成るシリンジポンプ装置では、以下のような問題がある。
（１）シリンジベース１０に設けた配線用スリット孔から、薬液等が浸入して、障害が発生する危険性が高くなる。 However, the conventional syringe pump device as described above has the following problems.
(1) From the wiring slit hole provided in the syringe base 10, a chemical solution or the like enters and the risk of occurrence of a failure increases.

（２）プッシャー４０の移動に伴い、信号線のたわみ量が変化するので、このたわみが稼動部に噛み込んだり、固定部に引っかからないような構造的な配慮が必要となり、メカ構造が複雑になる。 (2) As the pusher 40 moves, the amount of deflection of the signal line changes. Therefore, structural considerations are necessary so that this deflection does not bite into the operating part or catch on the fixed part, making the mechanical structure complicated. Become.

（３）信号線が繰返し伸縮することにより、断線等の問題が派生する。 (3) Problems such as disconnection are caused by repeated expansion and contraction of signal lines.

本発明に成るシリンジポンプ装置は、シリンジベース又は血液透析装置本体に一体保持されるシリンジベースと、該シリンジベースに保持されるシリンジと、モータで駆動される送りねじと、該送りねじに係合して直線運動可能なプッシャーと、を有し、前記プッシャーでシリンジの押し子を押圧し液体を送出する構成に加えて、プッシャー内部に、情報入力可能なＩＣタグが設けられると共に、シリンジベースに情報を検出するＩＣタグリーダーが設けられ、また、 A syringe pump device according to the present invention is engaged with a syringe base that is integrally held on a syringe base or a hemodialysis apparatus body, a syringe that is held on the syringe base, a feed screw that is driven by a motor, and the feed screw. And a pusher capable of linear movement, and in addition to a configuration in which the pusher of the syringe is pressed by the pusher to send out the liquid, an IC tag capable of inputting information is provided inside the pusher, and the syringe base An IC tag reader for detecting information is provided, and

着脱自在のシリンジの押し子と直線移動自在のプッシャーとの間に、該プッシャーの移動方向に転動変移可能でその先端部が電波遮蔽として機能する可動板が設けられ、シリンジの押し子のプッシャーへの装着に連動して前記電波遮蔽部が移動し、ＩＣタグとＩＣタグリーダーとの通信状態を変化させることで、シリンジの押し子の装着状態を検出するように構成され、また、 Between the pusher of the removable syringe and the linearly movable pusher, there is provided a movable plate that can roll and change in the direction of movement of the pusher and whose tip functions as a radio wave shield. The radio wave shielding unit moves in conjunction with the attachment to the device, and is configured to detect the attachment state of the syringe pusher by changing the communication state between the IC tag and the IC tag reader,

無線タグ機器から送信される電波の漏出により他の医療機器へ影響を及ぼす懸念の在る領域が、シリンジベース又は血液透析装置のパネルに表示されるように構成されている。 A region where there is a concern that leakage of radio waves transmitted from the wireless tag device may affect other medical devices is configured to be displayed on the syringe base or the panel of the hemodialysis apparatus.

本発明に成るシリンジポンプ装置は、上記のような構成であるから、信号線の断線や、スリット孔からの薬液等の浸入による弊害が無く、確実にシリンジの装着状態を検出して、安全な注入動作を可能にする。 Since the syringe pump device according to the present invention has the above-described configuration, there is no harmful effect caused by disconnection of the signal line or penetration of a chemical solution or the like from the slit hole, and it is possible to reliably detect the mounting state of the syringe and ensure safety. Allows injection operation.

以下図面により本発明の実施例を説明する。 Embodiments of the present invention will be described below with reference to the drawings.

図１〜図３は、第１の実施例で、制御装置７０と組合わせて、駆動モータ６０を回転すると、出力軸に接続されたギヤ列、送りネジ６４、送りナット６５の経路で動力が伝達され、パイプ５０をガイドにしてプッシャー４０がリニアに移動する構造は、前述した従来のシリンジポンプ装置と同様であるが、図１のように、シリンジの押し子２１の装着を検出する手段として、プッシャー４０内にアンテナと集積回路（ＩＣ）とを接続した回路を有したＩＣタグ７６と、該ＩＣタグ７６との間で無線通信を行うＩＣタグリーダー７５をシリンジベース１０に取付けることにより、シリンジベース１０の配線用スリット孔や配線用の中空パイプ、及びリード線を設けない点が、本発明構成の特徴である。（以後、これらＩＣタグ７６及び、ＩＣタグリーダー７６を纏めて、単に「ＩＣタグ機器」、双方の間で行われる通信を単に「ＩＣタグ機器間の通信」と称す。） FIGS. 1 to 3 show the first embodiment. When the drive motor 60 is rotated in combination with the control device 70, the power is transmitted along the path of the gear train, feed screw 64, and feed nut 65 connected to the output shaft. The structure in which the pusher 40 is linearly moved using the pipe 50 as a guide is the same as that of the conventional syringe pump device described above, but as a means for detecting attachment of the pusher 21 of the syringe as shown in FIG. By attaching to the syringe base 10 an IC tag 76 having a circuit in which an antenna and an integrated circuit (IC) are connected in the pusher 40, and an IC tag reader 75 that performs wireless communication with the IC tag 76, A feature of the configuration of the present invention is that a slit hole for wiring, a hollow pipe for wiring, and a lead wire are not provided in the syringe base 10. (Hereinafter, the IC tag 76 and the IC tag reader 76 are collectively referred to as “IC tag device”, and communication performed between the two is simply referred to as “communication between IC tag devices”.)

また、制御装置７０においては、前述のＩＣタグリーダー７５の信号を、制御部７２と接続している点が、従来品と異なる。尚、単独で動作が可能なシリンジポンプ装置では、ＩＣタグリーダー７５を含む制御装置７０の全てをシリンジポンプ装置に配置する必要があるが、血液装置に搭載されるシリンジポンプ装置では、これらの配置場所は特に限定されず、血液透析装置本体に、ＩＣタグリーダー７５を含む制御装置７０の全て、もしくはその一部を分散して配置することも可能である。以上が本発明に成るシリンジポンプ装置の構造概要である。 The control device 70 is different from the conventional product in that the signal from the IC tag reader 75 is connected to the control unit 72. In addition, in the syringe pump apparatus which can operate | move independently, it is necessary to arrange | position all the control apparatuses 70 including the IC tag reader 75 in a syringe pump apparatus, However, in the syringe pump apparatus mounted in a blood apparatus, these arrangement | positioning The location is not particularly limited, and all or a part of the control device 70 including the IC tag reader 75 can be distributed and arranged in the hemodialysis device body. The above is the outline of the structure of the syringe pump device according to the present invention.

次に、この構造を利用して、実際にシリンジの押し子装着の検出をどのように行うか、本発明品のプッシャーの内部構造概要を示した図１を用いて説明する。 Next, how to actually detect the attachment of the syringe pusher using this structure will be described with reference to FIG. 1 showing an outline of the internal structure of the pusher of the present invention.

４５は可動板で、一端に鉄板で形成された遮蔽部４６と、もう一端に取付け穴４７を有している。可動板４５は、取付け穴４７を介して、プッシャー４０に固定されているピン４８を中心に、転動可能に取付けられると共に、その一部が、ボタン４３及び、バネ４４の一部と当接するように配置されており、ボタン４３の位置の変化に連動して、遮蔽部４６が移動する構造となっている。 Reference numeral 45 denotes a movable plate having a shielding portion 46 formed of an iron plate at one end and a mounting hole 47 at the other end. The movable plate 45 is attached to be able to roll around a pin 48 fixed to the pusher 40 through an attachment hole 47, and a part of the movable plate 45 comes into contact with the button 43 and a part of the spring 44. The shielding part 46 moves in conjunction with the change in the position of the button 43.

今、シリンジの押し子２１が、装着されていな図１（B）の状態では、遮蔽部４６がＩＣタグ７６に近接して、電波が遮蔽される為、ＩＣタグ機器間の通信は不能となる。また、この状態から、図１（Ａ）のように押し子２１が鍔部４１に挿入されると、ボタン４３が押され、遮蔽部６５がＩＣタグ７６近傍から離れるように移動する為、ＩＣタグ機器間の通信が可能となる。 In the state of FIG. 1B where the syringe pusher 21 is not attached, the shielding portion 46 is close to the IC tag 76 and the radio wave is shielded, and therefore communication between IC tag devices is impossible. Become. Further, from this state, when the pusher 21 is inserted into the collar 41 as shown in FIG. 1A, the button 43 is pushed, and the shield 65 moves away from the vicinity of the IC tag 76. Communication between tag devices becomes possible.

一方、制御手段７２は、定期的にＩＣタグリーダー７５に対して所定周波数の電波を送信する指令を出し、この送信電波の応答としてＩＣタグ７６から予め記憶した情報の電波を、受信出来るか否かの判定を行うことで、押し子２１の装着状態を検出する。 On the other hand, the control unit 72 issues a command to periodically transmit a radio wave of a predetermined frequency to the IC tag reader 75, and whether or not the radio wave of information stored in advance from the IC tag 76 can be received as a response to the transmission radio wave. This determination makes it possible to detect whether the pusher 21 is mounted.

本発明の構成に成る制御部７２は、注入動作の開始時に、押し子２１の未装着状態が検出された場合には、警報器７４と表示器７３に警告（指令）を出すと共に、モータを動作させない安全機能を備えている。また、注入動作中に押し子２１の未装着状態が検出された場合には、警報器７４と表示器７３に警告（指令）を出すと共に、一定時間経過しても注入動作停止が行われない場合は、モータを自動停止する安全機能を備えている。本発明に成るシリンジポンプ装置は、このようにして押し子の装着状態を検出するように構成されている。 The control unit 72 having the configuration of the present invention issues a warning (command) to the alarm device 74 and the display device 73 when the pusher 21 is not attached at the start of the injection operation, and also activates the motor. It has a safety function that does not work. In addition, when an unmounted state of the pusher 21 is detected during the injection operation, a warning (command) is issued to the alarm device 74 and the display device 73, and the injection operation is not stopped even after a predetermined time has elapsed. If it has a safety function to automatically stop the motor. The syringe pump device according to the present invention is configured to detect the mounting state of the pusher in this manner.

次に、本発明における、ＩＣタグ機器の採用に伴う他の医療装置への電波の影響を配慮した構成について、図１及び図２を用いて説明する。 Next, a configuration in consideration of the influence of radio waves on other medical devices accompanying the adoption of the IC tag device in the present invention will be described with reference to FIGS.

本発明では、図１のように、外部から容易に確認が出来るように、シリンジベース１０のＩＣタグリーダー７５の近傍位置に目印１２をつけ、使用者に対し例えば「この目印を中心に半径２２ｃｍの範囲内に他の医療機器を近づけると、電波障害を受けることが懸念されます。」との注意喚起文書を記載したシール１３をシリンジベース１０に貼付すると共に、２２ｃｍの直線ライン１４をシリンジベース１０に付加表示している。 In the present invention, as shown in FIG. 1, a mark 12 is provided in the vicinity of the IC tag reader 75 of the syringe base 10 so that it can be easily confirmed from the outside. If another medical device is brought close to the range of, there is a concern that it may cause radio interference. ”A sticker 13 with a warning document that states“ Attachment to the syringe base 10 and a 22 cm straight line 14 is attached to the syringe base. 10 is additionally displayed.

この注意喚起に関して、例えば図２のように、透析装置本体にＩＣタグリーダー７５を搭載した場合では、同様の注意喚起文書を記載したシール８２を血液透析装置本体の前面パネル８０に貼付すると共に、更に直感的に電波の影響範囲が分かるようにＩＣタグリーダー７５の取付け位置近傍を中心とした円形ライン８１を付加表示しても善い。 With regard to this alerting, for example, as shown in FIG. 2, when an IC tag reader 75 is mounted on the dialyzer body, a seal 82 describing a similar alerting document is attached to the front panel 80 of the hemodialyzer body, Furthermore, it is also possible to additionally display a circular line 81 centering around the position where the IC tag reader 75 is attached so that the range of influence of radio waves can be intuitively understood.

尚、上述電波の影響範囲２２ｃｍの特定は、総務省の現時点での指針値を用いたものであり、特にこの数値に限定されるものではない。また、その注意喚起の表現や表示方法についても特に限定されない。 The specification of the above-mentioned radio wave influence range of 22 cm is based on the current guideline value of the Ministry of Internal Affairs and Communications, and is not particularly limited to this value. Moreover, the expression and display method of the alerting are not particularly limited.

本発明に成るシリンジポンプ装置は、シリンジの押し子の装着状態の検出を無線で行うシリンジポンプ装置として、特に有効である。 The syringe pump device according to the present invention is particularly effective as a syringe pump device that wirelessly detects the mounting state of a syringe pusher.
