Description

【0001】
【発明の属する技術分野】
本発明は、平板状の本体と、該本体の端部に設けられた流体入口及び出口と、これら入口及び出口間を結ぶ蛇行流路とを有し、前記蛇行流路は、前記平板状部材に穿設した流路形成用の溝を樹脂フィルムの溶着により閉寒して形成して成る医療用カートリッジの洗浄装置に関する。
【0002】
【従来の技術】
近年、輸血等を行うとき、低温液体を直接体内に注入するのを避け、温水で体温まで加温してから注入できる医療用カートリッジが開発された。これは、平板状の本体と、該本体の端部に設けられた流体入口及び出口と、これら入口及び出口間を結ぶ蛇行流路とを有し、前記蛇行流路は、前記平板状部材に穿設した流路形成用の溝を樹脂フィルムの溶着により閉寒して形成して成るものである。
【0003】
一般に、平板状の本体は、樹脂成型される。また、樹脂フィルムは、例えばポリカーボネイトフィルムとされ、平板状の本体両面に熱溶着される。
【0004】
医療用であるため、衛生上特別の気配りが必要である。例えば、樹脂フィルムの熱溶着は、クリーンルーム中で行われる。しかし、細心の注意を払っても、機械油の影響や、金属粉、或いは衣類等から発生した微量の細菌類の付着の可能性等があり、最終工程では、必ず何らかの洗浄手段が必要であった。
【0005】
従来の医療用カートリッジの洗浄は、専ら流路内に洗浄水を流すことのみで行われていた。洗浄水を流した後は、空気を送り、洗浄用の水を追い出して洗浄作業を終了する。これにより、ある程度の洗浄を行い得ることは明らかである。
【0006】
しかしながら、医療用カートリッジでは、流路溝を加工した板状部材の表面に薄い樹脂フィルムを熱溶着した構造であるので、洗浄水及び空気の送りに関して高圧とすることができず、十分な洗浄を行うことができなかった。また、流路溝を加工した板状部材の表面に樹脂フィルムを熱溶着した構造であるので流路断面に角があり、その部分で流速停溝するので、その部分に水溜り効果が生じ、小さな水滴が残ってしまうという問題があった。
【0007】
【発明が解決しようとする課題】
本発明は、上記従来技術に鑑みて、医療用カートリッジの流路に水滴が残らず、必要十分な洗浄を行うことができる医療用カートリッジでの洗浄装置を提供することを目的とする。
【0008】
【課題を解決するための手段】
上記課題を解決することのできる本発明の医療用カートリッジの洗浄装置は、平板状の本体と、該本体の端部に設けられた流体入口及び出口と、これら入口及び出口間を結ぶ蛇行流路とを有し、前記蛇行流路は、前記平板状部材に穿設した流路形成用の溝を樹脂フィルムの溶着により閉寒して形成して成る医療用カートリッジの洗浄装置において、
複数のカートリッジを並列に配置するコンテナと、該コンテナ中に配置したカートリッジの入口及び出口を1つに集合する集合管と、これら集合管に接続される洗浄水供給部及び乾燥空気供給部並びに真空引き部と、を備えたことを特徴とする。
【0009】
コンテナ中に並列に配置した複数のカートリッジを一度に洗浄処理できるので、効率良く洗浄できる。洗浄は、洗浄水を送り、乾燥空気を送って内部洗浄水を追い出し、次いで真空引きすることにより、樹脂フィルムと平板状の本体との間に残った水滴を確実に除去できる。
【0010】
洗浄水の供給及び乾燥空気の供給については、これらを圧送するのでは無く、吸引し、流路を常に負圧に保った方が好ましい。樹脂フィルムが平板状本体から剥離する方向の力を与えることが無く、流速大とすることができるからである。
【0011】
洗浄水を送るとき、最初のみ0.03MPs程度の圧力を掛け、ピンホール等の有無を調べるための耐圧テストを行って後、負圧による洗浄を行うこともできる。一般に、洗浄水の供給時間は、樹脂性の平板状の本体に樹脂フィルムを溶着した場合、内部流路に例えばゲージ圧で0.5Kg/cm以上の高圧を掛けることはできない。流路を負圧として吸引すれば、その2倍近い流速を得ることができる。
【0012】
また、本発明では、乾燥空気の供給に次いで内部を真空引きし、残留水分を蒸散させるので、流路構成に拘らず目に見える水滴は勿論のこと、全水分を除去できる。真空引きの程度は、室内又は加温温度に応じた水の飽和蒸気圧以下とすれば良い。室温20℃では、0.002337MPs(約17mmHg)以下である。水分は、元々微量であるので、真空引きの時間は数十秒間で十分である。これにより、流路内部の水分を略ゼロとすることができ、水滴残留をゼロとすることができ、衛生を保つことができる。
【0013】
さらに、各カートリッジの表面に紫外線を供給することにより、残留細菌の数を完全にゼロとすることができる。
【0014】
本発明では、洗浄水に殺菌ないし滅菌剤等の薬品を注入することは行わない。然るに、本発明では、殺菌ないし滅菌をカートリッジの上面側から紫外線を照射することで行うので、薬品の影響の心配が全く無く、カートリッジを医療用として安心して利用できる。
【0015】
【発明の実施の形態】
以下、添付図面を参照して本発明の実施の形態を説明する。図1は、本発明の一実施形態に係る医療用カートリッジの洗浄装置の構成を示す説明図、図2及び図3は、本発明を通用できる医療用カートリッジの一例を示す正面図及びその左側面図である。
【0016】
図2及び図3に示すように、医療用カートリッジ1は、平板状の本体2と、該本体の端部に設けられた流体入口3及び出口4と、これら入口3及び出口4間を結ぶ蛇行流路5とを有し、前記蛇行流路5は、前記平板状部材2に穿設した流路形成用の溝5を樹脂フィルム6の溶着により閉寒して形成して成る樹脂フィルム6は、例えばポリカーボネイトとされる。
【0017】
樹脂フィルム6は平板状の本体2に熱溶着される。熱溶着では、まず、樹脂フィルム6を図3に示すようにコの字形に折曲げ、これを本体2に装着し、両面から熱及び圧力を掛けて溶着する。これにより、溝5の開放面が樹脂フィルム6で閉寒され、閉じられた蛇行流路5が、形成される。しかしながら、樹脂フィルム6をコの字形に曲げる作業と、熱溶着の作業において人手又は機械類が作用するので、この間に蛇行流路5に機械油やゴミ類、或いは細菌が浸入する可能生が有る。
【0018】
本発明の医療用カートリッジ1の洗浄装置7は、図1に示すようにシステム構成されている。本例の医療用カートリッジの洗浄装置7は、複数のカートリッジ1を並列に配置するコンテナ8と、該コンテナ8中に配置したカートリッジ1の入口及び出口を1つに集合する集合管9A、9Bと、これら集合管管9A、9Bに接続される洗浄水供給部10及び乾燥空気供給部11並びに真空引き部12と、を備えている。各配管には、バルブV1、V2、V3、V4、V5、V6が介在されている。
【0019】
洗浄水供給部10は、ポンプBを備えるが、このポンプ13は、カートリッジ1の流体入口側と接続される集合管9Aに圧力を加えるのでは無く、蛇行流路5を負圧に保ちつつ他方の集合管9Bから圧力を引くようにしている。即ち、洗浄水供給部10は蛇行流路5の負圧を保つために、ギヤポンプ等による吸引用のポンプ13を設け、集合管9Aには、浄化後の水を吸引させる形とする。洗浄水の浄化のためには活性炭等による通常の浄化手段を用いる。メーカ指定等特別の理由がない限り薬剤は用いない。
【0020】
乾燥空気供給部11は、空気圧送用のポンプを設けず、真空ポンプ12で引いた分量の乾燥空気を供給するようにしている。バルブV2を閉じた状態でバルブV1を絞ることにより、蛇行流路5内部の真空度を高めることができる。
【0021】
前記コンテナ8は、一対のレール14上を走行可能とされ、レール14の前方(例えば手前)位置から、図示の作業位置へ移送される。
【0022】
作業位置の上方には、カートリッジ1の上方から各カートリッジ1に紫外線を照射する紫外線ランプ装置15が設けている。本例の紫外線ランプ装置15は、各カートリッジ1に対応する複数の紫外線ランプVLPを備えてなる。各紫外線ランプVLPは、例えば10W〜20Wの発光管から成り、下方に位置する。カートリッジ1に夫々紫外線を照射することができる。各カートリッジ1は、平面上で紫外線を受け、各流路を紫外線で照射滅菌すべく、斜め姿勢で設置するのが好ましい。
【0023】
以上の構成の医療用カートリッジ7において、洗浄処理は、次の手順で行われる。まず、紫外線照射ランプ装置15をオンとし、紫外線を当てながら、バルブV2、V3、V6を開け、水ポンプ13を駆動し、カートリッジ1に洗浄水を送る。蛇行流路5は負圧を保ちつつ、内部に高速で洗浄水が流される。洗浄終了時点では、バルブV3を閉じ、V2を開け、乾燥空気を送りつつ洗浄水を追い出す。次に、バルブV2、V4、V6を閉じ、V1、V5を開け、真空ポンプ12を駆動して、蛇行流路5内部に乾燥空気を送る。供給時間は数十秒程度でよい。
【0024】
最後に、バルブV1を閉じ又は絞り、蛇行流路5の内部の真空度を10〜15mmHgまで高める。真空度を高めると、水分の蒸散の終了時点で負荷大となるので、これを圧力計で検知し、真空引きを終了することができる。真空引き終了時点では、バルブV5を閉じ、バブルV1を介して蛇行流路5内に乾燥した清浄な空気を入れ、紫外線ランプ装置15をオフとし、全洗浄作業を終了する。連続した作業では、紫外線ランプ装置15はオンしたままとすることもできる。
【0025】
以上により、カートリッジ1の蛇行流路5の内部は洗浄され、水滴除去され、清浄で乾燥空気を充填した状態とすることができる。カートリッジ1の入口3及び出口4には図示しない盲栓を施して、製品とする。図2及び図3に示した樹脂フィルム6を熱溶着して成るカートリッジ1に過大な圧力を加えることなく高速に高度の洗浄処理を行うことができる。
【0026】
以上示した実施の形態では、洗浄水及び乾燥空気を集合管9Bからの吸引により与えたが、蛇行流路5に過大な圧力を与えない、例えば0.03〜0.05Ps程度までなら入口側の集合管9Aから圧入しても良い。
【0027】
本発明は、上記実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲で適宜の設計的変更を行うことができ、各種態様で実施できる。
【0028】
【発明の効果】
以上の通り、本発明は、特許請求の範囲に記載の通りの構成を有する医療用カートリッジの洗浄装置であるので、蛇行流路に洗浄水及び乾燥空気を送り、次いで真空引きすることができ、内部に水滴を残すことなく、高機能のカートリッジを効率良く製造することができる。
【0029】
また、洗浄中のカートリッジを紫外線ランプで照射すれば、微量の細菌類が残留する恐れも皆無とすることができ、より衛生的なカートリッジを効率良く製造することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention has a flat main body, a fluid inlet and an outlet provided at an end of the main body, and a meandering flow path connecting the inlet and the outlet, and the meandering flow path includes the flat member. The present invention relates to an apparatus for cleaning a medical cartridge, wherein a groove for forming a flow path formed in a medical cartridge is formed by welding and cooling a resin film to close the groove.
[0002]
[Prior art]
2. Description of the Related Art In recent years, a medical cartridge has been developed that can avoid injecting a low-temperature liquid directly into a body when performing blood transfusion and the like, and can inject the liquid after warming to body temperature with warm water. This has a flat main body, a fluid inlet and an outlet provided at an end of the main body, and a meandering flow path connecting the inlet and the outlet, and the meandering flow path is provided on the flat member. The perforated groove for forming a flow path is formed by closing a cold by welding a resin film.
[0003]
Generally, a flat main body is molded with resin. The resin film is, for example, a polycarbonate film, and is thermally welded to both surfaces of the flat main body.
[0004]
Because it is for medical use, special care is required for hygiene. For example, heat welding of a resin film is performed in a clean room. However, even with extreme caution, there is the possibility of the effects of machine oil and the possibility of adhesion of trace amounts of bacteria generated from metal powders or clothing, etc. Was.
[0005]
Conventionally, cleaning of a medical cartridge has been performed only by flowing cleaning water in a flow path. After the flushing water flows, air is sent to flush out the flushing water and finish the flushing operation. It is clear that this allows some cleaning.
[0006]
However, since the medical cartridge has a structure in which a thin resin film is heat-welded to the surface of the plate-shaped member having the flow channel formed therein, the high pressure cannot be applied to the supply of the cleaning water and air, and sufficient cleaning is performed. Could not do. Also, since the resin film is heat-welded to the surface of the plate-shaped member having the flow channel formed therein, there is an angle in the cross section of the flow channel, and the flow stops at that portion, so that a water pool effect occurs at that portion, There was a problem that small water droplets remained.
[0007]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and has as its object to provide a cleaning device using a medical cartridge that can perform necessary and sufficient cleaning without leaving water droplets in a channel of the medical cartridge.
[0008]
[Means for Solving the Problems]
The medical cartridge cleaning apparatus of the present invention that can solve the above-mentioned problems includes a flat main body, a fluid inlet and an outlet provided at an end of the main body, and a meandering flow path connecting the inlet and the outlet. Wherein the meandering channel is a medical cartridge cleaning apparatus formed by forming a channel for forming a channel formed in the flat member by closing the groove by welding a resin film.
A container for arranging a plurality of cartridges in parallel, a collecting pipe for collecting the inlets and outlets of the cartridges arranged in the container into one, a washing water supply unit, a dry air supply unit, and a vacuum connected to these collecting pipes And a pulling unit.
[0009]
Since a plurality of cartridges arranged in parallel in the container can be washed at a time, washing can be performed efficiently. In the cleaning, water droplets remaining between the resin film and the plate-shaped main body can be surely removed by sending cleaning water, sending dry air to drive out the internal cleaning water, and then applying vacuum.
[0010]
Regarding the supply of the washing water and the supply of the dry air, it is preferable that the pressure is not supplied, but the suction is performed and the flow path is always maintained at a negative pressure. This is because the flow rate can be increased without applying a force in a direction in which the resin film is separated from the flat main body.
[0011]
When sending the cleaning water, a pressure of about 0.03MPs may be applied only at the beginning, a pressure resistance test for checking the presence or absence of a pinhole or the like may be performed, and then cleaning with a negative pressure may be performed. In general, when a resin film is welded to a resin-made flat main body, a high pressure of, for example, 0.5 kg / cm 2 or more as a gauge pressure cannot be applied to the internal flow path when the cleaning water is supplied. If the flow path is suctioned with a negative pressure, a flow velocity nearly twice that of the suction can be obtained.
[0012]
Further, in the present invention, since the inside is evacuated after the supply of the dry air to evaporate the residual moisture, not only the visible water droplets but also all the moisture can be removed regardless of the flow path configuration. The degree of evacuation may be equal to or lower than the saturated vapor pressure of water depending on the room or heating temperature. At a room temperature of 20 ° C., the pressure is 0.002337 MPs (about 17 mmHg) or less. Moisture is originally very small, so that a vacuum time of several tens of seconds is sufficient. Thereby, the water content in the flow channel can be made substantially zero, the water droplet residue can be made zero, and hygiene can be maintained.
[0013]
Furthermore, by supplying ultraviolet rays to the surface of each cartridge, the number of residual bacteria can be completely reduced to zero.
[0014]
In the present invention, a sterilizing or sterilizing agent or other chemical is not injected into the washing water. However, in the present invention, since sterilization or sterilization is performed by irradiating ultraviolet rays from the upper surface side of the cartridge, there is no concern about the influence of chemicals, and the cartridge can be used safely for medical use.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an explanatory view showing the configuration of a medical cartridge cleaning apparatus according to an embodiment of the present invention. FIGS. 2 and 3 are front views and left side views showing an example of a medical cartridge which can be used in the present invention. FIG.
[0016]
As shown in FIGS. 2 and 3, the medical cartridge 1 includes a flat main body 2, a fluid inlet 3 and an outlet 4 provided at an end of the main body, and a meandering connection between the inlet 3 and the outlet 4. The meandering flow path 5 is formed by forming a groove 5 for forming a flow path formed in the flat plate member 2 and closing the groove 5 by welding the resin film 6 to cool the resin film 6. , For example, polycarbonate.
[0017]
The resin film 6 is thermally welded to the flat main body 2. In the thermal welding, first, the resin film 6 is bent into a U-shape as shown in FIG. 3, which is attached to the main body 2, and welded by applying heat and pressure from both sides. Thus, the open surface of the groove 5 is closed by the resin film 6 and the closed meandering channel 5 is formed. However, since the operation of bending the resin film 6 into a U-shape and the operation of the heat welding work with humans or machinery, there is a possibility that mechanical oil, dust or bacteria may enter the meandering channel 5 during this time. .
[0018]
The cleaning device 7 of the medical cartridge 1 according to the present invention has a system configuration as shown in FIG. The medical cartridge cleaning apparatus 7 of the present embodiment includes a container 8 in which a plurality of cartridges 1 are arranged in parallel, and collecting pipes 9A, 9B for collecting the inlets and outlets of the cartridges 1 arranged in the container 8 into one. A washing water supply unit 10, a dry air supply unit 11, and a vacuum unit 12 connected to the collecting pipes 9A and 9B are provided. Valves V1, V2, V3, V4, V5, V6 are interposed in each pipe.
[0019]
The cleaning water supply unit 10 includes a pump B. The pump 13 does not apply pressure to the collecting pipe 9A connected to the fluid inlet side of the cartridge 1, but maintains the meandering flow path 5 at a negative pressure while maintaining the meandering flow path 5 at a negative pressure. From the collecting pipe 9B. That is, the cleaning water supply unit 10 is provided with a pump 13 for suction using a gear pump or the like in order to maintain the negative pressure in the meandering flow path 5, and the collecting pipe 9A sucks purified water. For purifying the washing water, a normal purifying means using activated carbon or the like is used. Drugs are not used unless there is a special reason such as the manufacturer's designation.
[0020]
The dry air supply unit 11 does not include a pump for air pressure feeding, and supplies dry air in an amount reduced by the vacuum pump 12. By narrowing the valve V1 with the valve V2 closed, the degree of vacuum inside the meandering flow path 5 can be increased.
[0021]
The container 8 can travel on a pair of rails 14 and is transferred from a position in front of (for example, near) the rails 14 to a work position illustrated.
[0022]
Above the working position, an ultraviolet lamp device 15 for irradiating each cartridge 1 with ultraviolet light from above the cartridge 1 is provided. The ultraviolet lamp device 15 of this embodiment includes a plurality of ultraviolet lamps VLP corresponding to each cartridge 1. Each ultraviolet lamp VLP is composed of, for example, an arc tube of 10 W to 20 W, and is located below. Each cartridge 1 can be irradiated with ultraviolet light. Each cartridge 1 is preferably installed in an oblique position so as to receive ultraviolet rays on a plane and to sterilize each channel with irradiation with ultraviolet rays.
[0023]
In the medical cartridge 7 having the above configuration, the cleaning process is performed in the following procedure. First, the ultraviolet irradiation lamp device 15 is turned on, the valves V2, V3, and V6 are opened while the ultraviolet light is applied, and the water pump 13 is driven to send the cleaning water to the cartridge 1. While maintaining the negative pressure in the meandering flow path 5, the washing water flows at high speed inside. At the end of cleaning, the valve V3 is closed, V2 is opened, and the cleaning water is expelled while sending dry air. Next, the valves V2, V4, and V6 are closed, V1 and V5 are opened, and the vacuum pump 12 is driven to send dry air into the meandering channel 5. The supply time may be about several tens of seconds.
[0024]
Finally, the valve V1 is closed or throttled to increase the degree of vacuum inside the meandering channel 5 to 10 to 15 mmHg. If the degree of vacuum is increased, the load becomes large at the end of the evaporation of water, so that this can be detected by a pressure gauge and the evacuation can be ended. At the end of evacuation, the valve V5 is closed, dry clean air is introduced into the meandering channel 5 via the bubble V1, the ultraviolet lamp device 15 is turned off, and the entire cleaning operation is completed. In a continuous operation, the ultraviolet lamp device 15 can be kept on.
[0025]
As described above, the inside of the meandering channel 5 of the cartridge 1 can be washed, water droplets can be removed, and a state can be obtained in which the air is filled with clean and dry air. A blind plug (not shown) is provided at the inlet 3 and the outlet 4 of the cartridge 1 to obtain a product. Advanced cleaning can be performed at high speed without applying excessive pressure to the cartridge 1 formed by thermally welding the resin film 6 shown in FIGS.
[0026]
In the above-described embodiment, the cleaning water and the dry air are supplied by suction from the collecting pipe 9B. May be press-fitted from the collecting pipe 9A.
[0027]
The present invention is not limited to the above-described embodiment, and appropriate design changes can be made without departing from the gist of the present invention, and the present invention can be implemented in various modes.
[0028]
