Description

  The present invention relates to the in vivo administration of isotope-labeled liquid PET drugs such as 18F-FDG (2-deoxy-2-fluoro-D-glucose) used in positron emission tomography (hereinafter referred to as PET). Therefore, it is related with the auxiliary | assistant instrument of a manual type radioactive liquid administration apparatus used when performing a diagnosis and a test | inspection.

  Conventionally, a liquid PET drug such as 18F-FDG (2-deoxy-2-fluoro-D-glucose) labeled with a positron emitting isotope is administered into the body, and the distribution in the body is visualized with a special camera or the like. For example, a diagnostic method for cancer or the like is performed by PET, also called positron CT for performing diagnosis.

  18F-FDG (2-deoxy-2-fluoro-D-glucose) used in this PET is one in which one of the hydroxyl groups of glucose is substituted with 18-F, and the half-life, which is the life of the drug, is about 110 minutes. In addition, the energy of γ rays emitted by the pair annihilation between the positron emitted from the drug and the negative electron in the body is high, and the transmission capability of this energy is also high.

  Moreover, there is a limit to the radiation dose of PET drugs that can be obtained by delivery delivery, and the exposure dose is known to have little effect on the human body.

  When such a PET drug is administered to a subject (intravenous injection), it is important to ensure that it can be administered to the subject within a short period of time. This has led to a reduction in radiation exposure.

  For this reason, in recent PET inspection facilities, introduction of an automatic administration device for PET drugs has been promoted in consideration of exposure of medical workers.

  However, in addition to being very expensive, such an automatic administration device must always be administered manually if the device breaks down. Demand still exists.

  For this reason, improvement of the operation of the manual administration device is an issue, and it will continue to be widely used as a backup for the automatic administration device.

  Next, a procedure for administering a PET drug by a conventional manual radioactive liquid administration device T (for example, UG-150P) will be described.

  a. A manual radioactive liquid administration device T and a physiological saline syringe Q for washing out a PET drug are prepared.

  b. Prepare a radiation dose measuring device (Curie meter).

  c. The PET drug syringe P is set on the syringe shield S (for example, UG-150W), and the PET drug is sucked from the vial.

  d. The PET drug syringe P set on the syringe shield S is placed in front of the radiation dose measuring apparatus.

  e. The syringe shield S is unlocked, and the PET drug syringe P is removed from the syringe shield S.

  f. As shown in FIG. 6, the radiation dose of the PET drug sucked into the PET drug syringe P is measured by a radiation dose measuring device.

  g. After the measurement, with the needle attached to the PET drug syringe P, this is put into the syringe shield S.

  h. While holding the syringe shield S with one hand, the syringe is inserted with the lock released.

  i. The syringe shield S is locked and the setting of the PET drug syringe P is completed.

  j. As shown in FIG. 7, the syringe shield S is set on the manual radioactive liquid administration device T. The PET drug syringe P and the physiological saline syringe Q are connected via the three-way stopcock R.

  Further, the PET drug syringe P is connected to the injection line R2 for sending the PET drug to the patient via the three-way stopcock R.

  At this time, the piston side of the PET drug syringe P is connected to the tip of the pressing operation rod T1 of the manual radioactive liquid administration device T. When the pressing operation rod T1 of the manual radioactive liquid administration device T is pushed in, the piston of the PET drug syringe P is pushed.

k. The patient is given a PET drug and saline for washout. At this time, hold down with one hand firmly so that the three-way stopcock R does not come off due to pressure.
nothing special

  However, in the above-described PET drug administration procedure, when the manual radioactive liquid administration device T is used alone, the following problems occur.

  The first problem is that handling and operation of the physiological saline syringe Q and the three-way stopcock R are very difficult.

  The physiological saline syringe Q is for washing out the PET drug in the PET drug syringe P, and is connected to the PET drug syringe P via the three-way cock R.

  The three-way stopcock R initially functions to connect the PET drug syringe P and the input line R2 for feeding the PET drug to the patient.

  When the pressing operation rod T1 of the manual radioactive liquid administration device T is pushed in this state, the piston of the PET medicine syringe P is pushed, and the PET medicine in the PET medicine syringe P is fed into the charging line R2.

  At this time, since the PET drug in the PET drug syringe P is very small, a situation occurs in which the PET drug stays in the charging line R2.

  In order to avoid such a situation, first, the three-way stopcock R is rotated so that the PET drug syringe P and the physiological saline syringe Q function.

  In this state, the piston of the physiological saline syringe Q is pushed in, and at the same time, the push operation rod T1 of the manual radioactive liquid administration device T is pulled, and the piston of the PET drug syringe P is pulled out.

  Then, physiological saline is fed into the PET drug syringe P.

Then, simultaneously with pushing in the pressing operation rod T1 of the manual radioactive liquid administration device T,
Pull out the piston of the physiological saline syringe Q.

  Then, the PET drug remaining in the PET drug syringe P is fed into the physiological saline syringe Q together with the physiological saline.

  These operations are performed several times to wash out the PET drug remaining in the PET drug syringe P, and all the PET drug is fed into the saline syringe Q together with the physiological saline.

  Next, the three-way stopcock R is rotated to function so that the physiological saline syringe Q and the charging line R2 for feeding the PET drug to the patient are conducted.

  In this state, the piston of the physiological saline syringe Q is pushed in, and the remaining PET drug is fed into the charging line R2 together with the physiological saline.

  Then, the PET drug that has remained on the input line R2 from the beginning is administered to the patient so as to be pushed by the physiological saline.

  The remaining PET drug is also administered to the patient along with saline.

  In such a series of operations, the PET drug syringe P is set in the manual radioactive liquid administration device T. However, since there is no structure for supporting the saline syringe Q, the saline syringe Q is used by hand. It had to be held and supported firmly.

  However, it is very difficult to support the physiological saline syringe Q with the left hand and operate the piston of the physiological saline syringe Q with the left hand while operating the pressing operation rod T1 of the manual radioactive liquid administration device T with the right hand. Is.

  For this reason, a situation has arisen in which the physiological saline syringe Q is detached from the three-way stopcock R when the pressing operation rod T1 is being operated.

  In such a state, it is very difficult to rotate the three-way cock R with one hand while preventing the three-way cock R from falling off.

  And, for example, a three-acting shield made by Universal Giken (product name UG-150V) for operating the three-way stopcock R has been commercialized, but it is very expensive and used in actual medical demonstrations. In many cases, it is rarely purchased, and the operation of the three-way stopcock R is still difficult.

  In addition, as a second problem, when the manual radioactive liquid administration device T is used alone, it is difficult to handle various members and it takes time to operate them. Tended to increase.

  Furthermore, as a third problem, there has been no conventional countermeasure for removing contamination when the PET drug itself or physiological saline containing the washed-out PET drug leaks.

  For example, the PET drug syringe P, the physiological saline syringe Q, and the input line R2 for feeding the PET drug to the patient are connected via the three-way stopcock R, and the physiological saline syringe Q is supported as described above. Since there was no structure, the saline syringe Q had to be supported firmly by hand.

  However, since it is necessary to perform various operations in the manual radioactive liquid administration device T, the support is neglected, the physiological saline syringe Q is detached from the three-way stopcock R, and the physiological saline containing the PET drug is removed. There was a leaking situation.

  Further, when the PET drug syringe P and the three-way stopcock R are not firmly connected, the three-way stopcock R is detached from the PET drug syringe P and the PET drug leaks.

  Further, it is natural that the connection state between the PET drug syringe P and the three-way stopcock R, the connection state between the three-way stopcock R and the physiological saline syringe Q, and the connection state between the three-way stopcock R and the charging line R2 should be confirmed in advance. , You may forget that confirmation.

  In addition, they may come off due to carelessness, etc. In the unlikely event that a PET drug leaks, it is necessary to take immediate decontamination measures.

  Therefore, the present invention was created in view of the existing circumstances as described above. In the manual radioactive liquid administration device used for diagnosis using a PET drug, various members including a physiological saline syringe. In addition to providing safe and reliable administration of PET drugs to patients, reducing the dose of medical personnel, and taking sufficient measures to remove contamination when PET drugs leak It is an object of the present invention to provide an auxiliary device for a manual radioactive liquid administration device that is considered in the above.
