Abstract

<P>PROBLEM TO BE SOLVED: To enable a part containing a support pipe to expose outside by making a housing two-tiered up and down with a hole divided in half for penetrating the support pipe of a pusher, and to make the maintenance extremely easy. <P>SOLUTION: This syringe pump for the transfusion apparatus has a feed screw driven by a motor, and a pushing element of the syringe is pressed by the pusher capable of moving linearly which is engaged to the feed screw and supported by the support pipe. In this case, the housing 1 (1a and 1b) of the syringe pump for feeding a liquid is divided into upper and lower sections with a penetrating hole 8 of the support pipe divided into upper and lower sections. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は輸液装置用シリンジポンプ、特に、血液透析装置に用いる輸液装置用シリンジポンプに関するものである。   The present invention relates to a syringe pump for an infusion device, and more particularly to a syringe pump for an infusion device used in a hemodialysis apparatus.

一般に血液透析装置の働きは、「血液ポンプ」を使用して血液を体外に導き出して老廃物や余分な水分の除去、正常なイオン化等を行った後、再度血液を体内に戻す作業を行うことである。この時、体外に出た血液は、血管外の「異物」と接触して「凝固」する働きがあるので血液ポンプを用いて体外に出た血液の凝固を防ぐために通常は体外循環中の血液に抗凝固剤のヘパリンを持続的に注入する。このためのポンプをシリンジポンプと称している。   In general, the function of hemodialysis equipment is to use a “blood pump” to guide blood outside the body, remove waste and excess water, perform normal ionization, etc., and then return the blood to the body again. It is. At this time, blood that has flowed out of the body has the function of “coagulating” by contacting with “foreign substances” outside the blood vessel. The anticoagulant heparin is infused continuously. A pump for this purpose is called a syringe pump.

このような、輸液用シリンジポンプとしては特許文献１に示すものがある。
特開平１０−１９２３９８号公報 There exists a thing shown in patent document 1 as such a syringe pump for infusion.
Japanese Patent Laid-Open No. 10-192398

このような従来のシリンジポンプは図４及び図５に示すようにシリンジポンプのハウジング１を上下２段１ａ，１ｂに分割しており、上記ハウジング１の上段１ａにはシリンジ２の受け台３、シリンジ押えガイド４、シリンジ押し子用プッシャー５及びこのプッシャー５を摺動自在に支持する支持パイプ６等を有する。   As shown in FIGS. 4 and 5, such a conventional syringe pump divides the housing 1 of the syringe pump into upper and lower two stages 1a and 1b. A syringe presser guide 4, a syringe pusher pusher 5, and a support pipe 6 that slidably supports the pusher 5 are provided.

上記ハウジング１の下段１ｂにはシリンジベース７、上記プッシャー５の駆動源となるモータを動作するためのモータドライバ、ポンプに搭載されたセンサ信号の処理回路等を有する。   The lower stage 1b of the housing 1 has a syringe base 7, a motor driver for operating a motor that is a driving source of the pusher 5, a sensor signal processing circuit mounted on the pump, and the like.

なお、８はハウジング１の上段１ａに形成した上記支持パイプ６のための貫通孔である。   Reference numeral 8 denotes a through hole for the support pipe 6 formed in the upper stage 1 a of the housing 1.

然しながら、上記従来のシリンジポンプにおいては、上記ハウジング１の上段１ａ内にプッシャー５の支持パイプ６を含む部分が内蔵されており、これらの部分を露出できず、そのメンテナンスが困難となる欠点があった。   However, the conventional syringe pump has a drawback that the upper part 1a of the housing 1 includes the support pipe 6 of the pusher 5, and these parts cannot be exposed and the maintenance becomes difficult. It was.

本発明は上記の欠点を除くようにしたものである。   The present invention eliminates the above-mentioned drawbacks.

本発明の輸液装置用シリンジポンプは、モータで駆動される送りねじを有し、該送りネジに係合し支持パイプによって支持され直線運動可能なプッシャーによりシリンジの押し子を押圧し液体を送出する構成の輸液装置用シリンジポンプであって、上記シリンジポンプのハウジングが、上記支持パイプの貫通孔を上下に２分する形で上下２部分に分割されていることを特徴とする。   The syringe pump for an infusion device of the present invention has a feed screw driven by a motor, and pushes the pusher of the syringe with a pusher that is engaged with the feed screw and supported by a support pipe and can move linearly, thereby delivering the liquid. A syringe pump for an infusion device having a structure, wherein the housing of the syringe pump is divided into two upper and lower parts so as to divide the through hole of the support pipe into two vertically.

本発明の輸液装置用シリンジポンプにおいてはプッシャー５の支持パイプ６を貫通せしめる孔８を上下に２分する形でハウジング１を上下２段に分割したので支持パイプ６を含む部分を外部に露出でき、そのメンテナンスが極めて容易となる。   In the syringe pump for an infusion device of the present invention, the housing 1 is divided into two upper and lower parts so that the hole 8 penetrating the support pipe 6 of the pusher 5 is vertically divided, so that the portion including the support pipe 6 can be exposed to the outside. The maintenance becomes extremely easy.

以下図面によって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.

本発明においては図１〜図３に示すように上記プッシャー５の支持パイプ６の貫通孔８を上下に２分する形で上記ハウジング１を上下２部分１ａ，１ｂに分割せしめる。   In the present invention, as shown in FIGS. 1 to 3, the housing 1 is divided into two upper and lower parts 1a and 1b in such a manner that the through hole 8 of the support pipe 6 of the pusher 5 is divided into two vertically.

本発明の輸液装置用シリンジポンプにおいてはハウジング１を上下２段に分割したときプッシャー５の支持パイプ６部分が外部に露出される形となるため、露出されない場合に比べそのメンテナンスが極めて容易となる。   In the syringe pump for an infusion device of the present invention, when the housing 1 is divided into two upper and lower stages, the support pipe 6 portion of the pusher 5 is exposed to the outside, so that the maintenance becomes extremely easy compared to the case where it is not exposed. .
