Description

センサケースSensor case
　この発明は、血糖値を測定する血糖センサ等のシート状のセンサを収納し、血糖値測定装置等にこのセンサを供給するためのセンサケースに関する。 The present invention relates to a sensor case for storing a sheet-like sensor such as a blood glucose sensor for measuring a blood glucose level and supplying the sensor to a blood glucose level measuring device or the like.
　従来、例えば血糖値を測定するためのセンサである血糖センサは、シート状に形成されているものがある。このような血糖センサは、例えば基板の表面に対極、測定極、それらに連なる各リード、絶縁層が設けられ、対極と測定極を覆う反応層が形成され、さらに基板の表面に、スペーサとカバーを順次固定したものである。血糖センサは、例えば、開閉自在な密閉容器に収納されており、使用する時は１枚ずつ取り出して血糖値測定装置に装着し、血糖センサに血液を付けることで血糖値が測定される。 Conventionally, for example, a blood glucose sensor that is a sensor for measuring a blood glucose level is formed in a sheet shape. In such a blood glucose sensor, for example, a counter electrode, a measurement electrode, leads connected to them and an insulating layer are provided on the surface of the substrate, a reaction layer covering the counter electrode and the measurement electrode is formed, and a spacer and a cover are formed on the surface of the substrate. Are fixed sequentially. For example, the blood glucose sensor is housed in an openable / closable sealed container. When the blood glucose sensor is used, the blood glucose sensor is taken out one by one and attached to the blood glucose measuring device, and blood glucose is measured by attaching blood to the blood glucose sensor.
　血糖センサに素手で触れると正しい測定値が得られないことがあり、取り扱いに注意が必要である。また、血糖センサは使い捨てであり、血糖値測定装置に装着して使用された後に廃棄され、次の測定には新しい血糖センサを使用する。そこで、このような血糖センサを複数個収納し、血糖値測定装置に１個ずつ供給する血糖センサ供給装置や血糖センサケースが提供されている。 ∙ If the blood glucose sensor is touched with bare hands, correct measurement values may not be obtained, and handling is necessary. In addition, the blood glucose sensor is disposable and is discarded after being mounted on the blood glucose level measurement device, and a new blood glucose sensor is used for the next measurement. Therefore, there are provided a blood glucose sensor supply device and a blood glucose sensor case for storing a plurality of such blood glucose sensors and supplying them one by one to the blood glucose level measuring device.
　例えば特許文献１のセンサ供給装置の場合、センサ送出口を有するセンサ貯蔵ケースと、前記センサ送出口近傍に設けられたセンサ送出手段が設けられている。センサ送出手段は、一対のセンサ送出ローラがセンサ取出口に沿って設けられている。センサ貯蔵ケース内には、乾燥剤が配置されている。 For example, in the case of the sensor supply device of Patent Document 1, a sensor storage case having a sensor delivery port and a sensor delivery means provided in the vicinity of the sensor delivery port are provided. The sensor delivery means is provided with a pair of sensor delivery rollers along the sensor outlet. A desiccant is disposed in the sensor storage case.
　特許文献２のセンサカートリッジは、センサを積層収納するカートリッジケースと、このカートリッジケースに設けられセンサが搬出される出口と、この出口からセンサを搬出するスライドプレートが設けられ、出口には、スライドプレートによる搬出動作に連動して出口を開閉するシャッタが設けられている。 The sensor cartridge of Patent Document 2 is provided with a cartridge case in which the sensors are stacked and stored, an outlet provided in the cartridge case from which the sensor is carried out, and a slide plate from which the sensor is carried out. A shutter that opens and closes the outlet in conjunction with the unloading operation is provided.

　このようなセンサケースは、センサケースから血糖センサを差し出した状態で血糖値測定装置の差込口に入れて、糖値測定装置の係止手段に血糖センサを保持させた後、センサケースを血糖値測定装置から離すと、血糖センサが血糖値測定装置の差込口に残り、血糖値が測定可能となる。しかしながら、センサケース側の保持力が強すぎると、糖値測定装置側に血糖センサ先端部が挿入されても、センサケースを糖値測定装置から離すと血糖センサも付いてきて、血糖値測定装置から血糖センサが脱落してしまうことがある。また、センサケース側の保持力が弱すぎると、測定作業前に血糖センサがセンサケースから脱落してしまう恐れがある。このように、センサケースは、血糖値測定装置に血糖センサを良好に挿入するために適した保持力に設定することが必要である。 In such a sensor case, the blood glucose sensor is inserted from the sensor case into the insertion port of the blood glucose level measuring device, and the blood glucose sensor is held by the locking means of the sugar level measuring device, and then the sensor case is attached to the blood glucose level. When separated from the value measuring device, the blood glucose sensor remains in the insertion port of the blood glucose measuring device, and the blood glucose level can be measured. However, if the holding force on the sensor case side is too strong, even if the blood glucose sensor tip is inserted on the sugar level measuring device side, the blood glucose sensor is also attached when the sensor case is separated from the sugar level measuring device. Blood glucose sensor may fall off. Further, if the holding force on the sensor case side is too weak, the blood glucose sensor may fall off from the sensor case before the measurement work. As described above, the sensor case needs to be set to a holding force suitable for inserting the blood glucose sensor into the blood glucose level measuring apparatus satisfactorily.
　しかし、上記背景技術の特許文献１の場合、大がかりな駆動機構を備えたセンサ供給装置であり、血糖センサはセンサ供給装置でローラにより保持され、保持力が高いため血糖値測定装置側の保持力をより強くしないと血糖センサを抜き取れないものであり、保持力の調節が難しく、装置も複雑化するものであった。特許文献２の場合、センサを押圧しているスプリングの位置が収納状体でセンサ中央部であり、センサカートリッジからセンサを差し出した状態では、センサがスプリングにより保持されない位置であり、センサの保持力が弱く、センサが不用意に落下してしまう恐れがある。 However, in the case of Patent Document 1 of the above background art, it is a sensor supply device having a large drive mechanism, and the blood glucose sensor is held by a roller in the sensor supply device and has a high holding force, so that the holding force on the blood glucose level measuring device side is high. The blood glucose sensor cannot be pulled out unless the strength is increased, making it difficult to adjust the holding force and complicating the apparatus. In the case of Patent Document 2, the position of the spring that presses the sensor is the housing-like body in the center of the sensor, and when the sensor is inserted from the sensor cartridge, the sensor is not held by the spring, and the holding force of the sensor Is weak and the sensor may fall inadvertently.
　この発明は、上記背景技術の問題点に鑑みてなされたものであり、シート状のセンサを１枚ずつ正確且つ容易に取り出すことができ、適切な保持力で測定装置に挿入可能であり、確実に測定を行うことができるセンサケースを提供することを目的とする。 The present invention has been made in view of the above problems of the background art, and can take out sheet-like sensors accurately and easily one by one, and can be inserted into a measuring apparatus with an appropriate holding force. It is an object of the present invention to provide a sensor case capable of performing measurement.

　前記取出口の周縁部には、前記ケース本体内側に突出する重なり防止突部が設けられ、前記一番端の前記センサには前記重なり防止突部が当接せずに前記取出口を通過させ、二番目の前記センサには前記重なり防止突部が当接するように形成されたものである。 At the peripheral edge of the outlet, there is provided an overlap prevention protrusion that protrudes inside the case main body, and the overlap prevention protrusion does not abut on the sensor at the extreme end to pass the extraction outlet. The second sensor is formed so that the overlap preventing protrusion comes into contact therewith.

The spring guide wall 72 is fitted on the inside of the pair of spring guide walls 32 of the case main body 14 with a clearance and is slidable. In the vicinity of the push-up wall 66 of the push-up slider 64, a through hole 74 that penetrates the side surface of the push-up slider 64 is provided.
　押上スライダ６４のスプリング用ガイド壁７２の内側には、弾性体である圧縮されたスプリング７６が設けられている。スプリング７６は、ケース本体１４の底面部１８ｄと押上スライダ６４の押上壁６６に当接し、押上スライダ６４をケース本体１４の第１ガイド壁２４に向かって付勢する。 A compressed spring 76 that is an elastic body is provided inside the spring guide wall 72 of the push-up slider 64. The spring 76 contacts the bottom surface portion 18 d of the case main body 14 and the push-up wall 66 of the push-up slider 64, and urges the push-up slider 64 toward the first guide wall 24 of the case main body 14.
　次に、センサケース１０の組立方法の一例について説明する。センサケース１０のケース本体１４に取出スライダ５２、スプリング７６、押上スライダ６４を所定位置にセットし、ケース蓋体３４を、カバー部材４４を外した状態でケース本体１４に取り付け、図６に示す状態となる。取出スライダ５２は、背面部１８ｃ側に位置している。そして押上部６０のコの字形の内側の空間に取出スライダ用ガイド壁３３が位置している。このとき押上スライダ６４は、スプリング７６により第１ガイド壁２４側に付勢されているため、ケース蓋体３４の切欠部３９から押上スライダ６４が露出する。 Next, an example of a method for assembling the sensor case 10 will be described. The take-out slider 52, the spring 76, and the push-up slider 64 are set at predetermined positions on the case main body 14 of the sensor case 10, and the case lid 34 is attached to the case main body 14 with the cover member 44 removed, as shown in FIG. It becomes. The take-out slider 52 is located on the back surface portion 18c side. The take-out slider guide wall 33 is located in the space inside the U-shape of the push-up portion 60. At this time, since the push-up slider 64 is urged toward the first guide wall 24 by the spring 76, the push-up slider 64 is exposed from the notch 39 of the case lid 34.
　次に、押上スライダ６４の透孔７４に図示しないピン等を差し込み、スプリング７６の付勢力に対抗して押上スライダ６４を移動させ、開かれた空間に血糖センサ１２を入れる。血糖センサ１２は、上面部１８ａに対して平行に複数枚を重ねて入れる。透孔７４からピン等を抜いて押上スライダ６４をフリーにすると、押上スライダ６４が血糖センサ１２を押して、押上スライダ６４と受け部である第１ガイド壁２４及び図示しない第３ガイド壁とに挟持され、ガタツキを防ぐ。この後、カバー部材４４を切除部３９に取り付けて図４に示すようにセンサケース１０が使用可能となる。血糖センサ１２は湿気に弱いため、センサケース１０ごと乾燥材入りの防湿容器に保管すると良い。防湿容器は、血糖センサ１２を使用した後に密封可能なものである。 Next, a pin or the like (not shown) is inserted into the through hole 74 of the push-up slider 64, the push-up slider 64 is moved against the urging force of the spring 76, and the blood glucose sensor 12 is inserted into the open space. A plurality of blood glucose sensors 12 are stacked in parallel to the upper surface portion 18a. When a pin or the like is removed from the through hole 74 to make the push-up slider 64 free, the push-up slider 64 pushes the blood glucose sensor 12 and is sandwiched between the push-up slider 64 and the first guide wall 24 and the third guide wall (not shown). And prevent rattling. Thereafter, the cover member 44 is attached to the cut portion 39, and the sensor case 10 can be used as shown in FIG. Since the blood glucose sensor 12 is sensitive to moisture, the sensor case 10 may be stored in a moisture-proof container containing a desiccant. The moisture-proof container can be sealed after the blood glucose sensor 12 is used.
　次にセンサケース１０の使用方法について説明する。先ず、取出スライダ５２を、図１、図４のように背面部１８ｃ側の位置から、図２、図５に示すように、正面部１８ｂ側の位置にスライドさせる。このとき、上面部１８ａの両端部に設けられた係止突部２１が、取出スライダ５２の係止凹部６２に嵌合されてクリック感を生じるとともに位置決めされ、後述する血糖値測定装置に血糖センサ１２を挿入するときに、取出スライダ５２が押し戻されることがない。ここで、図１、図４に示すように取出スライダ５２が背面部１８ｃ側に位置しているとき、取出スライダ５２の押出突起６３は、第２ガイド壁２８にほぼ一致している。図２、図５に示すように取出スライダ５２が正面部１８ｂ側に位置しているとき、押出突起６３の先端は、押上スライダ６４の段部６８の取出口４９側端部よりも取出口４９側に位置し、後端は段部６８の背面部１８ｃ側に位置している。そして、取出スライダ５２を取出口４９側へ移動させると、押出突起６３は一枚目の血糖センサ１２の背面部１８ｃ側の端部に当接して、取出スライダ５２の移動とともに一枚目の血糖センサ１２を移動させ、取出口４９から血糖センサ１２が所定長さ突出する。このとき、血糖センサ１２の背面部１８ｃ側の端部は、ケース本体１４の第１ガイド壁２４と押上スライダ６４の押上壁６６に挟まれて保持され、押上壁６６の段部６８よりも取出口４９側に位置している。押上スライダ６４の押上壁６６には、中間部に段部６８が設けられ、さらにスプリング７６は、取出口４９と反対側の背面側の位置で付勢しているため、取出口４９側では血糖センサ１２が落下しない程度に弱い保持力で保持される。 Next, how to use the sensor case 10 will be described. First, the take-out slider 52 is slid from the position on the back face 18c side as shown in FIGS. 1 and 4 to the position on the front face 18b side as shown in FIGS. At this time, the locking protrusions 21 provided at both ends of the upper surface portion 18a are fitted into the locking recesses 62 of the take-out slider 52 to cause a click feeling and are positioned, and the blood glucose sensor is installed in a blood glucose level measuring device to be described later. When inserting 12, the take-out slider 52 is not pushed back. Here, as shown in FIGS. 1 and 4, when the take-out slider 52 is positioned on the back surface 18 c side, the push-out protrusion 63 of the take-out slider 52 substantially coincides with the second guide wall 28. As shown in FIGS. 2 and 5, when the take-out slider 52 is located on the front surface 18 b side, the tip of the push-out protrusion 63 is more than the take-out port 49 side end of the step 68 of the push-up slider 64. The rear end is located on the back surface 18 c side of the stepped portion 68. When the take-out slider 52 is moved to the outlet 49 side, the push-out protrusion 63 comes into contact with the end of the first blood glucose sensor 12 on the back surface 18c side, and the first blood glucose is moved along with the movement of the take-out slider 52. The sensor 12 is moved, and the blood glucose sensor 12 protrudes from the outlet 49 by a predetermined length. At this time, the end of the blood glucose sensor 12 on the side of the back surface 18c is held between the first guide wall 24 of the case body 14 and the push-up wall 66 of the push-up slider 64, and is removed from the step 68 of the push-up wall 66. Located on the exit 49 side. The push-up wall 66 of the push-up slider 64 is provided with a stepped portion 68 at the intermediate portion, and the spring 76 is urged at the position on the back side opposite to the take-out port 49. The sensor 12 is held with a holding force that is weak enough not to fall.
そして、血糖センサ１２が所定長さに突出した状態で、センサケース１０を図示しない血糖値測定装置に近づけ、血糖センサ１２を所定位置に挿入する。この後、保持されたことを確認し、センサケース１０を引くと、血糖センサ１２が血糖値測定装置に保持されて、血糖値測定装置側に残る。そして、測定用の血液等を所定位置に載せ血糖値を測定する。 Then, with the blood glucose sensor 12 protruding to a predetermined length, the sensor case 10 is brought close to a blood glucose level measuring device (not shown), and the blood glucose sensor 12 is inserted into a predetermined position. After that, when the sensor case 10 is pulled after confirming that it has been held, the blood glucose sensor 12 is held by the blood glucose level measuring device and remains on the blood glucose level measuring device side. Then, blood glucose for measurement is placed on a predetermined position to measure the blood sugar level.
　また、図７に示すように、最後の一枚の血糖センサ１２を血糖値測定装置に装着するとき、押上スライダ６４の段部６８の立ち上がりは、垂直または鋭角であるため、取出スライダ５２の押出突起６３が血糖センサ１２から外れても段部６８に係止されて止められるため、血糖センサ１２がセンサケース１０内に押し戻されることがない。 As shown in FIG. 7, when the last blood glucose sensor 12 is attached to the blood glucose level measuring device, the rise of the stepped portion 68 of the push-up slider 64 is vertical or acute, so that the take-out slider 52 is pushed out. Even if the protrusion 63 is detached from the blood glucose sensor 12, the blood glucose sensor 12 is not pushed back into the sensor case 10 because it is locked and stopped by the stepped portion 68.
　取出口４９の重なり防止突部２３は、第１ガイド壁２４に当接している一番端の血糖センサ１２には当接せずに取出口４９を通過させ、二番目の血糖センサ１２には当接して重なって複数枚出てくることを防いでいる。 The protrusion preventing portion 23 of the outlet 49 passes through the outlet 49 without contacting the first blood glucose sensor 12 in contact with the first guide wall 24, and passes through the outlet blood glucose sensor 12. It prevents a plurality of sheets from coming into contact and overlapping.
　この実施形態のセンサケース１０によれば、シート状の血糖センサ１２を１枚ずつ確実に取り出し、血糖値測定装置に挿入して確実に血糖値測定装置側に血糖センサ１２を装着することができる。しかも、最後の一枚まで確実に取り出すことができる。取出スライダ５２を操作するだけで、血糖センサ１２に素手で触れることがなく、簡単に血糖値測定装置に装着することができ、正確に血糖値を測定することができる。さらに、センサケース１０の組み立てや、血糖センサ１２の装填は簡単であり、押上スライダ６４を透孔７４にピン等を差し込んで移動し血糖センサ１２を装填することができ、ラインの自動化に対応することができる。また、カバー部材４４を透明な材料で作ることにより、血糖センサ１２の残量を目視することが可能である。 According to the sensor case 10 of this embodiment, the sheet-like blood glucose sensors 12 can be reliably taken out one by one, inserted into the blood glucose measuring device, and the blood glucose sensor 12 can be securely attached to the blood glucose measuring device. . In addition, the last one can be reliably removed. By simply operating the take-out slider 52, the blood glucose sensor 12 can be easily attached to the blood glucose measuring device without touching the blood glucose sensor 12, and the blood glucose level can be accurately measured. Furthermore, the assembly of the sensor case 10 and the loading of the blood glucose sensor 12 are simple, and the push-up slider 64 can be moved by inserting a pin or the like into the through hole 74 to load the blood glucose sensor 12, which corresponds to the automation of the line. be able to. Moreover, the remaining amount of the blood glucose sensor 12 can be visually observed by making the cover member 44 from a transparent material.

　次に、センサケース８０の組立方法の一例について説明する。センサケース８０のケース本体１４に、取出スライダ５２、スプリング７６、押上スライダ６４を所定位置にセットする。そして押上スライダ６４の透孔７４に図示しないピン等を差し込み、スプリング７６の付勢力に対抗して押上スライダ６４を移動させ、開かれた空間に血糖センサ１２を入れる。血糖センサ１２は、摺動ガイド部３５に対して平行に複数枚を重ねて入れる。透孔７４からピン等を抜いて押上スライダ６４をフリーにすると、押上スライダ６４が血糖センサ１２を押して、押上スライダ６４と受け部となる摺動ガイド部３５に挟持され、ガタツキを防ぐ。この後、ケース蓋体３４を取り付けてセンサケース８０が使用可能となる。 Next, an example of a method for assembling the sensor case 80 will be described. The take-out slider 52, the spring 76, and the push-up slider 64 are set at predetermined positions on the case body 14 of the sensor case 80. Then, a pin (not shown) or the like is inserted into the through hole 74 of the push-up slider 64, the push-up slider 64 is moved against the urging force of the spring 76, and the blood glucose sensor 12 is put into the open space. A plurality of blood glucose sensors 12 are put in parallel with the sliding guide portion 35. When a pin or the like is removed from the through-hole 74 to make the push-up slider 64 free, the push-up slider 64 pushes the blood glucose sensor 12 and is sandwiched between the push-up slider 64 and the sliding guide portion 35 serving as a receiving portion to prevent rattling. Thereafter, the case lid 34 is attached and the sensor case 80 can be used.
　次にセンサケース８０の使用方法について説明する。先ず、取出スライダ５２を、図８、図１２のように背面部１８ｃ側の位置から、図９、図１４に示すように、正面部１８ｂ側の位置にスライドさせる。ここで、図８に示すように取出スライダ５２が背面部１８ｃ側に位置しているとき、取出スライダ５２の押出突起６３は背面部１８ｃ側に位置し、取出スライダ５２を取出口４９側へ移動させると、押出突起６３は一枚目の血糖センサ１２の背面部１８ｃ側の端部に当接して、取出スライダ５２の移動とともに一枚目の血糖センサ１２を移動させ、取出口４９から血糖センサ１２が所定長さ突出する。このとき、血糖センサ１２の背面部１８ｃ側の端部は、摺動ガイド部３５の裏面及び取出スライダ５２の押出部６０と押上スライダ６４の押上壁６６とに挟まれて保持される。押上スライダ６４の押上壁６６には、取出口４９と反対側に段部６８が設けられ、さらにスプリング７６は、中央部よりも背面部１８側の位置で付勢しているため、取出口４９側では血糖センサ１２が落下しない程度に弱い保持力で保持される。 Next, how to use the sensor case 80 will be described. First, the take-out slider 52 is slid from the position on the back face 18c side as shown in FIGS. 8 and 12 to the position on the front face 18b side as shown in FIGS. Here, as shown in FIG. 8, when the take-out slider 52 is located on the back surface 18c side, the push-out protrusion 63 of the take-out slider 52 is located on the back surface portion 18c side, and the take-out slider 52 is moved to the outlet 49 side. Then, the push-out protrusion 63 contacts the end of the first blood glucose sensor 12 on the back surface 18c side, and moves the first blood glucose sensor 12 along with the movement of the take-out slider 52. 12 projects a predetermined length. At this time, the end of the blood glucose sensor 12 on the side of the back surface portion 18c is held by being sandwiched between the back surface of the sliding guide portion 35 and the push-out portion 60 of the take-out slider 52 and the push-up wall 66 of the push-up slider 64. The push-up wall 66 of the push-up slider 64 is provided with a stepped portion 68 on the side opposite to the take-out port 49 and the spring 76 is biased at a position closer to the back surface 18 than the center portion. On the side, the blood glucose sensor 12 is held with such a weak holding force that it does not fall.
　そして、血糖センサ１２が所定長さに突出した状態で、センサケース８０を図示しない血糖値測定装置に近づけ、血糖センサ１２を所定位置に挿入する。この後、保持されたことを確認し、センサケース８０を引くと、血糖センサ１２が血糖値測定装置に保持されて、血糖値測定装置側に残る。そして、測定用の血液等を所定位置に載せ血糖値を測定する。 Then, with the blood glucose sensor 12 protruding to a predetermined length, the sensor case 80 is brought close to a blood glucose level measuring device (not shown), and the blood glucose sensor 12 is inserted into a predetermined position. Thereafter, when it is confirmed that the sensor case 80 is pulled, the blood glucose sensor 12 is held by the blood glucose level measuring device and remains on the blood glucose level measuring device side. Then, blood glucose for measurement is placed on a predetermined position to measure the blood sugar level.
　この実施形態のセンサケース８０も、上記実施形態と同様の効果を有し、外ケース８４とともに用いることにより、より安定な品質を保持することができる。 The sensor case 80 of this embodiment has the same effect as that of the above embodiment, and can be used with the outer case 84 to maintain more stable quality.
　なお、この発明のセンサケースは、上記実施の形態に限定されるものではなく、センサは、血糖値の測定以外に体液や温度等の情報を検知するものや各種診断用のセンサでも良く、用途や大きさは自由に変更可能である。ケース本体の形状もセンサの形状や収納する数に合わせて自由に設計することができる。また、弾性体は、スプリング以外に適した付勢力を有するものであればよい。 The sensor case of the present invention is not limited to the above-described embodiment, and the sensor may be a sensor for detecting information such as body fluid and temperature in addition to the measurement of blood glucose level or a sensor for various diagnoses. The size can be changed freely. The shape of the case body can also be freely designed according to the shape of the sensor and the number of housings. Moreover, the elastic body should just have urging | biasing force suitable other than a spring.
