Description

[Detailed description of the invention] The present invention relates to an octopus tube in an infusion set,
In particular, it facilitates fixation to the patient's arm, and
The present invention relates to an octopus tube that is characterized by convenient handling during needle puncture, etc.

In recent years, the importance and necessity of infusion therapy has increased, and it is widely used by children and adults for various diseases. This infusion therapy aims to achieve an immediate effect by injecting a medicinal solution directly into a vein, and is a so-called drip therapy. This drip treatment is usually 500mm per tube.
The required number of medicinal solutions are injected intravenously over a period of 40 minutes to 1.5 hours or more, and during the infusion, the patient cannot move the arm where the intravenous needle has been inserted, making it difficult for the patient. is a treatment that requires inconvenience. For this infusion, an infusion set is used, which consists of an octopus tube equipped with an intravenous needle, an infusion tube connected to the octopus tube, and an infusion barrel equipped with a drip and bottle needle attached to the infusion tube.

As shown in FIG. 1, a conventional octopus tube 1 includes a pipe 4 with a vein 2 removably attached to one end, an infusion tube 3 detachably attached to the other end, and a pipe 4 protruding from approximately the center of the pipe 4. It consisted of an integrally formed internal hollow air storage chamber 5. This air retention chamber 5 is for the purpose of trapping air bubbles, if any, in the medicinal solution flowing into the intravenous needle 2 from the infusion tube 3, thereby preventing the risk of air being injected into the blood vessel. The octopus tube 1 is also used to fix the intravenous needle 2 to the patient's arm, and when fixing it, the necessary parts of the octopus tube 1 are fixed to the patient's arm with adhesive tape such as plaster. was. However, the air retention chamber 5 of the Octopus tube 1 has a shape that protrudes from the pipe 4, and since the main body of the Octopus tube 1 is formed from the pipe 4, the bottom area is narrow, lacks stability, and is difficult to handle. 2 is difficult to puncture into a patient's vein and fix using an adhesive tape such as a plaster, and a certain level of skill is required to secure it properly. On the other hand, when puncturing the venous needle 1 into the patient's arm, etc., the octopus tube 1
However, since the air retention chamber 5 protrudes and the overall length of the octopus tube itself is long, handling is inconvenient, and it is not easy to carry out intravenous injection while holding the octopus tube 1. Nakatsuta. That is, the octopus tube 1 has the functions of an air reservoir, a gripping part during venous needle puncture, and a part for fixing the venous needle 2 to the patient's arm. Since the chamber 5 protrudes, it is difficult to handle, making venous needle puncture and fixation a troublesome task.

Therefore, in order to eliminate such inconvenience in handling, a winged needle 6 as shown in FIG. At the same time, one end of an infusion tube 8 of an appropriate length is connected to the intravenous needle 2a, and a connecting attachment 9 is attached to the other end of the infusion tube 8. The connecting attachment 9 is used by being attached to the tip of the pipe 4 of the octopus tube 1 from which the venous needle 2 has been removed.
According to such a winged needle 6, since the anchoring wings 7 are flexible, it can be easily fixed to a patient's arm or the like using an adhesive tape. Note that the octopus tube 1 is arranged at a portion separated by an appropriate distance from the fixed portion by the infusion tube 8. However, when puncturing the venous needle 2a into the human body, the anchoring wings 7 are too flexible and soft, and cannot securely hold the venous needle 2a.
There are still concerns that the inconvenience of intravenous injections has not been resolved. Further, since the winged needle 6 is used by being attached to the tip of the pipe 4 from which the intravenous needle 2 of the octopus tube 1 has been removed, the total length of the infusion set becomes longer, which causes inconvenience in its handling. Moreover, since such an infusion set is discarded each time it is used and a large number of sets are required during the treatment period, using the winged needle 6 other than the octopus tube 1 would place an economic burden on the patient. Become.

Furthermore, when administering an intravenous drip to a child using the above-mentioned type of intravenous needle, the child may not be able to overcome the fear of injections;
In addition, doctors, doctors,
It is a difficult treatment for both children. Furthermore, the negative effects of treatment on the psychology of children who feel that something strange is stuck to their arm are difficult to estimate. Therefore, the present invention aims to improve the octopus tube in the conventional infusion set, and has a main body made of a substantially rectangular hollow cube with an attachment tube for an intravenous needle and an infusion tube formed so as to be able to communicate with the internal hollow part. If necessary, the outside surface of the main body can display designs of cars, animals, or other designs that children like. Hereinafter, the configuration of the present invention will be explained based on an embodiment shown in FIGS. 3 to 6.

FIG. 3 shows an octopus tube 1 used especially when infusion therapy is to be administered to children. 4 to 6 show the basic structure of the octopus tube 1 shown in FIG. 3, as well as the octopus tube 1 to be generally used. In the figure, the main body 10 is a substantially rectangular cube, and is made of a transparent material as a base material of a synthetic resin suitable for infusion therapy. Reference numeral 11 is formed inside the main body 1 in a chamber forming the air storage chamber 5. 1
Reference numeral 2 denotes an attachment tube for the infusion tube 3, which is formed on the short side of the main body 1 and communicates with the inner chamber 11. Reference numeral 13 denotes an attachment tube to which the intravenous needle 2 is detachably attached, and is formed on the short side of the main body 1 facing the attachment tube 12, and is connected to the inner chamber 11.
It communicates with Reference numeral 14 denotes a shielding wall that protrudes from the main body 10 in parallel to the attachment tube 13 in order to protect the attachment tube 13. The attachment pipes 12 and 13 face each other at the lower part of the inner chamber 4, so that a large space is formed at the upper part of the inner chamber 11.

If necessary, a car, animal, or other pattern that children like is displayed on the outer surface of the main body 10. Third
As shown in the figure, a car figure 16 is printed on the side of the main body 1.
Alternatively, the animal figure 17 is displayed on the top surface by embossment or printing. Furthermore, the main body 10 may be formed in the form of a car. The octopus tube 1 for children may be given as a toy to a child after the infusion is completed.

Therefore, when using the octopus tube 1 according to the present invention, the intravenous needle 2 can be punctured into the human body by pinching both sides of the main body 10 with fingers, making it convenient to handle during intravenous injection. Due to its shape, the bottom surface can be stably fixed to the patient's body, and the bottom area is wide, making it extremely easy to fix it to the patient's arm. Furthermore, since the octopus tube 1 is made into a substantially rectangular cube, the overall length can be made shorter than that of the conventional example, which, together with the shape, makes handling convenient.

As described above, according to the present invention, since the octopus tube is made of a substantially rectangular cube, the bottom surface has a stable shape, and the bottom surface is wide, so that it can be easily and stably fixed to the human body. It is easy to handle because intravenous injections can be made by pinching both sides with your fingers. Moreover, when using the octopus tube of this invention,
Since the fixation is extremely easy, there is no need to use a winged needle as in the past, and there is no need to impose an economic burden on the patient. Furthermore, since the entire structure can be made shorter than the conventional example, it is easier to handle. Furthermore, by displaying a pattern that children like on the outside of the octopus tube, you can alleviate fear and anxiety without giving the child a strange feeling, and maximize the effectiveness of infusion therapy. can be raised. Moreover, the cubic body has better moldability and is easier to manufacture than conventional octopus tubes, and can be mass-produced at low cost.
