Description
The present invention relates to a column for generating a cancer diagnostic agent of a radiopharmaceutical, and more particularly, to a medicine containing radioactive substance in an aqueous solution which is used for cancer diagnosis. The present invention relates to a column for generating a cancer diagnostic agent for radiopharmaceuticals, which can prevent breakage and improve the adsorption efficiency of the adsorbent.
Although cancer diagnostic agents in radiopharmaceuticals generally tend to avoid radiation from radioactive materials, the reason for such high usage is that radioactive materials have a unique characteristic of having high permeability. It is developing rapidly.
When using a cancer diagnostic agent of radiopharmaceuticals, in consideration of stability, a column for generating a cancer diagnostic agent is supplied to a company in order to generate a cancer diagnostic injection solution. so the adsorbent is filled into the container is to maintain the shape stability to the filter, and both ends of the glass container, but using these cancer diagnosis column coupled to the closure member that can be fitted to the needle Hexi molybdenum on the inside of the glass container (Mo - 99 ) with an adsorbent obtained by adsorbing alumina packed in the form of sodium molybdate and a column equipped with a filter.In the case of using a cancer diagnostic agent, a reactant made of Nacl or the like is injected into the column to adsorbent. the reaction process generates tekeune ryumsan sodium (Tc -99m) and that in passing in contact with the elution using a cancer diagnostic agent consisting of an injection solution And there.
Conventional cancer diagnostic column was covered with a ring-shaped escape prevention cap made of alumina around the sealing member coupled to both ends of the glass container to be fixed to the organic container bar, in the process of transporting or storing such cancer diagnostic column Not only did the glass container be damaged by the impact generated when the protruding alumina release cap is in contact, but also the needle bent in one direction with the needle bent at least one step into the sealing member. It was inconvenient to use because it could not be fixed.
In addition, in the conventional cancer diagnostic column, since the inner surface of the sealing member located inside both ends of the glass container is in a state of being in close contact with the felt-type filter, the reactant injected into the filter through the needle inserted into the sealing member is removed from the filter. Since the contact with the adsorbent in the form of eccentricity through one side is not evenly distributed to the adsorbent, the adsorption efficiency is reduced.
In order to solve this problem, the column for generating a cancer diagnostic agent of a radiopharmaceutical is combined with a sealing member made of silicon on both ends of the glass container, but has a protruding end with a diameter larger than the outer diameter of the glass container on the outside of the locking jaw. In addition, it has a protective function of the glass container and forms an expansion pipe guide groove on the inner side of the sealing member located inside both ends of the glass container of the cancer diagnostic column, and the reactant injected through the sealing member spreads widely through the filter to the adsorbent. As a means of contacting to increase the adsorption efficiency, and also to elute the injection solution is eluted to the center to increase the elution efficiency.
In addition, the present invention is provided with a needle insertion groove on the outer surface of the sealing member to be inserted in the needle insertion groove bent portion of the needle bent in more than one stage to fix the bent installation direction of the needle.
The present invention comprises a glass container made of a rod-shaped tubular body and provided with a transparent body, an adsorbent filled in a powder form inside the glass container, and an upper and lower filters in close contact to maintain the form stability of the adsorbent, Combine the porous support plate with a plurality of through holes formed in close contact with the bottom of the lower filter and the sealing member made of silicon on the upper and lower ends of the glass container, respectively, the diameter larger than the outer diameter of the glass container outside the locking jaw of the sealing member. And a column for generating a cancer diagnostic agent of a radiopharmaceutical formed by forming a protruding end portion and an expansion-shaped guide groove on the inner surface of the sealing member.
The column for generating the cancer diagnostic agent of the radiopharmaceutical of the present invention is formed at the upper and lower portions of the glass container with a diameter larger than the outer diameter of the glass container on the outside of the locking jaw of the sealing member to prevent breakage of the glass container. In addition, expansion pipe guide grooves are formed on the inner side of the sealing member, respectively, and the reactants injected through the upper sealing member are uniformly contacted with the adsorbent to greatly increase the adsorption efficiency, and the injection solution eluted through the lower filter is focused. To facilitate elution.
In addition, the present invention has an effect such that the needle insertion groove is formed on the outer surface of the upper, lower sealing member to ensure the safe and convenient use of the needle and to accurately insert the tip of the needle into the center of the sealing member. have.
