Description

注射器充填装置syringe filling device
  本発明は、注射器に関する。 The present invention relates to syringes.
　例えば、予防接種は、注射器を用いて行われる（例えば、特許文献１から５参照。）。注射器には、薬液を充填する必要がある。注射器に予め薬液を充填して販売されることがあるが、薬液の種類によっては、患者への接種の前に、医師や看護師等の医療従事者により、注射器に薬液を充填する必要がある。しかし、接種の都度、注射器への薬液の充填を人手で行うことは、医療従事者の作業負担を増大させている。 For example, vaccination is performed using a syringe (see Patent Documents 1 to 5, for example). The syringe needs to be filled with the drug solution. Syringes are sometimes sold pre-filled with drug solutions, but depending on the type of drug solution, medical professionals such as doctors and nurses must fill the syringes with the drug solution before inoculating patients. . However, manually filling the syringe with the drug solution each time inoculation increases the workload of the medical staff.

　バイアル保持器２２は、注射器１０の針１３が刺されたバイアル３０を保持する。バイアル保持器２２は、バイアル３０の容器３１が重力方向上側になり、バイアル３０の蓋３２が重力方向下側となるよう、バイアル３０を保持する。例えば、バイアル保持器２２は、バイアル３０の容器３１の肩を支えるように、バイアル３０を保持する。バイアル保持器２２は、バイアル３０を嵌め込み可能な形状を有していてもよい。しかし、バイアル保持器２２がバイアル３０を保持する機構は、特に限定されない。バイアル保持器２２の材料は、例えば樹脂、及び金属であるが、特に限定されない。 The vial holder 22 holds the vial 30 pierced by the needle 13 of the syringe 10. The vial holder 22 holds the vial 30 so that the container 31 of the vial 30 faces upward in the direction of gravity and the lid 32 of the vial 30 faces downward in the direction of gravity. For example, the vial retainer 22 holds the vial 30 so as to support the shoulder of the container 31 of the vial 30 . The vial holder 22 may have a shape into which the vial 30 can be fitted. However, the mechanism by which the vial holder 22 holds the vial 30 is not particularly limited. The material of the vial holder 22 is, for example, resin and metal, but is not particularly limited.
　シリンジ保持器２１と、バイアル保持器２２と、は、直列に配置される。第１実施形態に係る注射器充填装置は、シリンジ保持器２１とバイアル保持器２２を保持する基板４０をさらに備えていてもよい。基板４０は、例えば、重力方向と略平行に、シリンジ保持器２１とバイアル保持器２２を保持する。基板４０の材料は、例えば樹脂、金属、及び木材であるが、特に限定されない。 The syringe holder 21 and the vial holder 22 are arranged in series. The syringe filling device according to the first embodiment may further include a substrate 40 holding the syringe holder 21 and the vial holder 22 . The substrate 40 holds the syringe holder 21 and the vial holder 22 substantially parallel to the direction of gravity, for example. The material of the substrate 40 is, for example, resin, metal, and wood, but is not particularly limited.
　プランジャー駆動部２３は、例えば、回転体２３１と、回転体２３１の回転軸外に接続されたロッド２３２と、ロッド２３２に接続され、注射器１０のプランジャー１１に接続されるプランジャー接続部２３３と、を備える。回転体２３１、ロッド２３２、及びプランジャー接続部２３３のそれぞれの材料は、例えば樹脂、及び金属であるが、特に限定されない。 The plunger drive unit 23 includes, for example, a rotating body 231, a rod 232 connected to the outside of the rotation axis of the rotating body 231, and a plunger connecting part 233 connected to the rod 232 and connected to the plunger 11 of the syringe 10. And prepare. Materials for the rotating body 231, the rod 232, and the plunger connecting portion 233 are, for example, resin and metal, but are not particularly limited.
　回転体２３１は、円盤であってもよいし、クランクであってもよい。回転体２３１は、モーター等の回転装置２３４で回転させられてもよい。ロッド２３２は、回転体２３１の回転軸ではない部分に、ヒンジピン等の第１ピン２３３４により、可動接続される。プランジャー接続部２３３は、ロッド２３２に、ヒンジピン等の第２ピン２３３３により、可動接続される。 The rotating body 231 may be a disc or a crank. The rotating body 231 may be rotated by a rotating device 234 such as a motor. The rod 232 is movably connected to a portion of the rotating body 231 that is not the rotating shaft by a first pin 2334 such as a hinge pin. The plunger connecting portion 233 is movably connected to the rod 232 by a second pin 2333 such as a hinge pin.
　プランジャー接続部２３３は、プランジャー１１と嵌合する嵌合部２３３２と、嵌合部に接続されたロッド形状部２３３１と、を備えていてもよい。ロッド２３２と、プランジャー接続部２３３のロッド形状部２３３１と、が、第２ピン２３３３で接続されていてもよい。また、プランジャー接続部２３３は、プランジャー１１のフランジ１６を保持してもよい。プランジャー接続部２３３が、プランジャー１１のフランジ１６を両側から挟むように保持することにより、プランジャー１１に対して上下方向の力を加えることが可能である。 The plunger connecting portion 233 may include a fitting portion 2332 that fits with the plunger 11, and a rod-shaped portion 2331 connected to the fitting portion. The rod 232 and the rod-shaped portion 2331 of the plunger connecting portion 233 may be connected by the second pin 2333 . The plunger connection portion 233 may also hold the flange 16 of the plunger 11 . The plunger connecting portion 233 holds the flange 16 of the plunger 11 so as to sandwich it from both sides, so that it is possible to apply a force in the vertical direction to the plunger 11 .
　回転体２３１の回転運動は、ロッド２３２及びプランジャー接続部２３３で、上下運動に変換される。そのため、回転体２３１が回転すると、プランジャー接続部２３３に接続されたプランジャー１１の端部が下死点と上死点との間で往復する。 The rotary motion of the rotating body 231 is converted into vertical motion by the rod 232 and the plunger connecting portion 233 . Therefore, when the rotating body 231 rotates, the end of the plunger 11 connected to the plunger connecting portion 233 reciprocates between the bottom dead center and the top dead center.
　注射器１０のシリンジ１２は、空の状態で、シリンジ保持器２１で保持される。また、図４に示すように、注射器１０のプランジャー１１は、シリンジ１２が空の状態で、プランジャー接続部２３３によって最もシリンジ１２内に押し込まれたときに、シリンジ１２内に空間が残るように、プランジャー接続部２３３に接続される。換言すれば、ガスケット１５の上死点と、針１３の間のシリンジ１２内に空間が残るように、プランジャー１１はプランジャー接続部２３３に接続される。 The syringe 12 of the syringe 10 is held by the syringe holder 21 in an empty state. Also, as shown in FIG. 4, the plunger 11 of the syringe 10 is designed so that a space remains in the syringe 12 when the syringe 12 is in an empty state and the plunger connecting portion 233 pushes the plunger 11 into the syringe 12 as far as possible. , is connected to the plunger connection portion 233 . In other words, the plunger 11 is connected to the plunger connection 233 such that a space remains in the syringe 12 between the top dead center of the gasket 15 and the needle 13 .
　回転体２３１が回転し、プランジャー１１が下死点に移動すると、図５に示すように、バイアル３０内の薬液５０が、シリンジ１２内に移動する。注射器１０は、プランジャー１１を重力方向下側にして配置されているため、シリンジ１２内において、薬液５０は、ガスケット１５上にたまり、薬液５０の層の上に、空気層が形成される。 When the rotor 231 rotates and the plunger 11 moves to the bottom dead center, the drug solution 50 in the vial 30 moves into the syringe 12 as shown in FIG. Since the syringe 10 is arranged with the plunger 11 facing downward in the direction of gravity, the liquid medicine 50 accumulates on the gasket 15 in the syringe 12 and an air layer is formed on the layer of the liquid medicine 50 .
　さらに回転体２３１が回転し、プランジャー１１が上死点に移動すると、シリンジ１２内の空気が、バイアル３０内に押し出される。バイアル３０は、針１３が刺される蓋３２が重力方向下側となるよう配置されているため、バイアル３０の容器３１内において、空気は、薬液５０の層の上に上がる。 When the rotating body 231 rotates further and the plunger 11 moves to the top dead center, the air inside the syringe 12 is pushed out into the vial 30 . Since the vial 30 is arranged so that the lid 32 into which the needle 13 is pierced is located downward in the direction of gravity, air rises above the layer of the liquid medicine 50 in the container 31 of the vial 30 .
　したがって、回転体２３１が回転運動を繰り返し、プランジャー１１が上下運動を繰り返すと、バイアル３０内の薬液５０がシリンジ１２内に吸引され、シリンジ１２内の空気がバイアル３０内に押し出されることが繰り返される。適当な量の薬液５０がシリンジ１２内に吸引された後に、回転体２３１を止める。目視により、適当な量の薬液５０がシリンジ１２内に吸引されたことを確認して回転体２３１を止めてもよいし、適当な量の薬液５０がシリンジ１２内に吸引されることに相当する回転体２３１の回転数を予め求め、所定の回転数に達したときに、回転体２３１を自動的に止めてもよい。 Therefore, when the rotating body 231 repeats the rotary motion and the plunger 11 repeats the vertical motion, the drug solution 50 in the vial 30 is sucked into the syringe 12 and the air in the syringe 12 is pushed out into the vial 30 repeatedly. be After an appropriate amount of the liquid medicine 50 is sucked into the syringe 12, the rotating body 231 is stopped. The rotation body 231 may be stopped after confirming that an appropriate amount of the chemical solution 50 has been sucked into the syringe 12 by visual observation. The number of revolutions of the rotating body 231 may be obtained in advance, and the rotating body 231 may be automatically stopped when the predetermined number of revolutions is reached.
　適当な量の薬液５０がシリンジ１２内に吸引された後、注射器１０は、シリンジ保持器２１及びプランジャー駆動部２３から外され、針１３がバイアル３０から引き抜かれ、患者の治療に使用される。 After an appropriate amount of drug solution 50 has been aspirated into syringe 12, syringe 10 is removed from syringe holder 21 and plunger driver 23, needle 13 is withdrawn from vial 30, and used to treat a patient. .
　基板４０上において、バイアル保持器２２とシリンジ保持器２１の間の距離は変更可能であってもよい。また、基板４０上において、シリンジ保持器２１とプランジャー接続部２３３の間の距離は変更可能であってもよい。これにより、シリンジ１２の大きさの変更に対応可能である。 The distance between the vial holder 22 and the syringe holder 21 on the substrate 40 may be changeable. Also, the distance between the syringe holder 21 and the plunger connection 233 may be variable on the substrate 40 . This makes it possible to adapt to changes in the size of the syringe 12 .
　従来、注射器への薬液の充填は、患者の治療の前に、医師や看護師等の医療従事者により行われていた。これに対し、第１実施形態に係る注射器充填装置によれば、注射器への薬液の充填を自動的に行えるため、医療従事者の作業負担を軽減することが可能である。また、例えば、パンデミックの際には、大量の患者に注射をする必要がある。大量の患者の一人一人に注射する前に、都度、注射器への薬液の充填を人手で行うことは、医療従事者の作業負担を増大させる。これに対し、第１実施形態に係る注射器充填装置によれば、注射器への薬液の充填を自動的に行えるため、パンデミックの際にも、医療従事者の作業負担を軽減することが可能である。 Conventionally, medical staff such as doctors and nurses filled syringes with drug solutions before treating patients. On the other hand, according to the syringe filling device according to the first embodiment, it is possible to automatically fill the syringe with the drug solution, and thus it is possible to reduce the work burden on the medical staff. Also, for example, during a pandemic, there is a need to inject a large number of patients. Manually filling syringes with drug solutions before injecting a large number of patients individually increases the workload of medical staff. On the other hand, according to the syringe filling device according to the first embodiment, it is possible to automatically fill the syringe with the drug solution, so it is possible to reduce the work burden on the medical staff even in the event of a pandemic. .
