TECHNICAL FIELD OF THE INVENTION
The present invention relates to a dual needle protection container used in the medical field, in particular, a blood circuit for artificial dialysis, an infusion set, and the like, and more particularly, can be easily manufactured, and is effective when protecting and using two kinds of needles. It relates to a certain double needle protection container.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in a blood circuit for artificial dialysis, an infusion set, and the like (hereinafter, referred to as artificial dialysis, etc.), various protectors, that is, protective cylindrical containers are used. In recent years, as containers such as saline are shifting from plastic bottles to soft bags, there is still a demand for a method of incorporating an air needle. For example, as shown in the side view of FIG. One end (or base) 11 has a plastic needle (or bottle needle) A (see FIG. 3) incorporated therein, and the other end 12 has an air needle B (see FIG. 3) incorporated therein. Have been. This type of protector II has the other end which is open when the air needle B is incorporated or not depending on the usage method of the user at the hospital or the like. Is closed by inserting urethane foam or sponge. In addition, as shown in FIG. 7, when a plastic needle A and an air needle B are used, a protector 2 for protecting the plastic needle A and a protector 3 for protecting the air needle B are provided. These are manufactured separately and are used by being fitted and connected linearly at their ends against each other, or as shown in FIG. 8, a protector 2 and a protector 3 facing each other in parallel and a cellophane tape or the like. It is known to wind and fix it.
[0003]
[Problems to be solved by the invention]
However, in the case of the protector as described above, the one shown in FIG. 6 needs to be closed in advance with urethane or sponge, etc. when used for an application that does not require the air needle B. Not only that, the entire length is long, so that there is a problem in that in the case of steam sterilization, a bend is generated, and the air needle B is incorporated, which may come into contact with the tube wall to generate chips. 7 has a problem that the protector 2 and the protector 3 are fitted in a straight line so that the length is long as in FIG. 6, so that the handling is not easy. Further, the one shown in FIG. 8 has a problem that not only is it complicated in manufacturing but also the appearance of the product is not good in that the protector 2 and the protector 3 face each other in parallel and are fixed by winding a cellophane tape or the like. is there.
[0004]
Therefore, the present inventors have conducted various studies on the above problems, and found that the protector 2 and the protector 3 face each other in parallel, and are annularly connected in the vicinity of a needle insertion portion (hereinafter, referred to as a base) of one of the protectors. By providing a part, by fixing the other protector by fitting the tip of the other protector to the connecting part, not only the entire container becomes compact because the entire length is halved, but also bending due to steam sterilization is prevented, The present inventors have found that the appearance is good, the commercial value is improved, the mold is easy to mold, the mold itself can be made compact, and the cost can be reduced, and the present invention has been made.
[0005]
Therefore, the problem to be solved by the present invention is that bending during steam sterilization can be prevented, the whole becomes compact and easy to handle, the commercial value is improved, the mold is easily formed, and the mold itself can be made compact. To provide a dual needle protection container that is economical.
