Description

  The present invention relates to a needle tip guide device used when a needle tip of a double-ended needle is inserted into a rubber stopper that seals a medicine bottle in which a medicine or the like is stored.

  Currently, in medical facilities such as hospitals, a method of administering a drug solution M in a drug bottle 30 to a patient via an infusion tube 60 as shown in FIG. 32 is a rubber stopper for connecting the drip tube 60.

  Usually, such a chemical M is stored in a state where it is separated into a solid drug X and a liquid chemical Y as shown in FIG. 8A in order to prevent secular change, and immediately before use. In addition, the drug X and the drug solution Y are mixed to make a drug solution M, and the drug solution M is administered to the patient.

  As a device for communicating between the inside of the medicine bottle 20 containing the medicine X and the inside of the medicine bottle 30 containing the medicine Y, a double-ended needle 10 having a configuration as shown in FIG. It is used. Such a double-ended needle 10 has a central portion of a double-ended needle main body 11 having needle tips formed at both ends at the central portion of a disc-shaped support plate 13 that partitions the central portion of the cylindrical cover portion 12. The structure is fixed in a penetrating state.

  When the drug X and the drug Y are mixed to make the drug M, as shown in FIG. 8A, one of the double-ended needle main bodies 11 is attached to a rubber stopper that seals the drug bottle 20. After the needle tip of the side is stabbed, the other needle tip is stabbed into a rubber stopper 32 that seals the inside of the bottle mouth 31 of the medicine bottle 30 as shown in FIG. 8B. 20 and the inside of the medicine bottle 30 are made to communicate with each other. In such a state, the drug solution Y is put in the drug bottle 20 to dissolve the drug X, and the solution is collected again in the drug bottle 30. Then, the double-ended needle 10 is removed from the drug bottle 30, and the production of the drug solution M is completed.

  In the process of mixing the drug X and the drug solution Y described above, as shown in FIG. 9A, a double-ended needle is attached to the rubber stopper 22 that seals the inside of the bottle mouth 21 of the drug bottle 20. If the needle tip of the main body 11 is to be inserted in a state where the needle tip is inclined rather than perpendicular to the upper surface of the plug 22, the outer diameter of the double-ended needle main body 11 is thicker than that of a normal injection needle, and thus the needle tip. In some cases, the stopper 22 is pushed into the tip of the medicine bottle 20 without being stabbed. In this way, in the state where the plug body 22 has fallen as shown in FIG. 9B, there is a possibility that the drug X may be contaminated by contact with the outside air. It cannot be administered and must be disposed of. In FIGS. 9A and 9B, reference numeral 23 denotes a metal member for fixing the stopper 22 to the bottle mouth 21.

  That is, conventionally, when the double-ended needle body 11 is not pierced in the direction perpendicular to the upper surface of the plug body 22 of the medicine bottle 20, there is a possibility that the medicine X in the medicine bottle 22 is wasted.

  In order to solve the above problems, the present invention has a needle tip penetrating the plug body of a drug bottle containing a drug or a chemical solution inside and sealed with a rubber plug body at both ends. A double-ended needle that is fixed in a state where the central portion of the double-ended needle body that penetrates the central portion of a disc-shaped support plate provided so as to close the central portion inside the cylindrical cover portion; A needle tip guide device interposed between the bottle mouth of a medicine bottle, comprising a combination of a cylindrical bottle side guide member and a cylindrical needle side guide member, and the cylindrical bottle side guide A top plate having a through-hole at the center is disposed on one opening side of the member, and the inner diameter of the bottle-side guide member is selected to be approximately equal to the outer diameter of the bottle opening of the drug bottle. The top of the bottle mouth can be crowned, and the inner diameter of the cylindrical needle side guide member is the bottle side guide. The outer diameter of the needle-side guide member is selected to be approximately equal to the inner diameter of the cylindrical cover portion of the double-ended needle, and the needle-side guide member is The bottle-side guide member can be fitted inside the needle-side guide member, and the bottle-side guide member can be fitted inside the needle-side guide member. Here, when the bottle side guide member is fitted inside the cover part of the double-ended needle with the bottle side guide member fitted inside the needle side guide member, the bottle side guide member The needle side guide member and the bottle side guide member may be fixed in a state where the top plate portion is positioned so as to be able to contact the support plate of the double-ended needle.

  According to the present invention, since the needle tip of the double-ended needle body can be surely inserted in a direction perpendicular to the upper surface of the plug body into the plug body sealing the drug bottle, the plug body is prevented from falling off. Can do.
