Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement of an octopus tube connected to the tip of an infusion blood transfusion set.

(Prior Art) It is well known that an octopus tube is generally attached to the tip of an infusion blood transfusion set for purposes such as venting air.

FIG. 5 shows an example of an infusion set, in which the medicinal solution introduced from the bottle needle 30 is temporarily stored in the drip tube 31, and then the drip flow rate is adjusted by the clamp 32, and the drip tube 33 and the rubber tube 34 are It is injected into the body through the octopus tube 35 and from the injection needle 36 connected to the tip of the octopus tube 35.

(Problems to be Solved by the Invention) In such an infusion set, after the injection needle 36 is inserted into a blood vessel, the octopus tube 35 is fixed to the patient's arm with tape.
Since the tacho tube generally has a shape close to a cylindrical shape, there are problems such as the octopus tube rotating and shifting even after taping. Further, even when absorbent cotton is placed at the bottom of the octopus tube 35 to give an angle, there is a drawback that the octopus tube and the absorbent cotton tend to come off easily and are difficult to fix.

Furthermore, when co-injecting two types of medicinal solutions, it is necessary to use a special infusion set with, for example, a separate infusion tube connected to the chamber;
If, after using an infusion set as shown in the figure, an attempt is made to co-inject other types of medicines in an emergency, there is the inconvenience that the entire infusion set must be replaced.

The present invention was proposed as a result of studies to solve these problems.

(Means for Solving the Problems) As shown in FIG. 1 corresponding to the embodiment, the present invention branches the rear end of the octopus tube main body 1 into a Y-shape, and one branch 4 is used to guide liquid. This is used as a connection port for the tube 6, and the other branch part 7 is closed with a rubber stopper 8 to form a mixed injection part.

(Function) Since the rear end of the octopus tube body 1 is Y-shaped, it is possible to stably set the octopus tube body without rotating it. Further, if necessary, a co-infusion needle can be inserted into the rubber stopper 8 to mix in other types of medicinal solutions.

(Example) FIGS. 1 and 2 show an example of the present invention. In the figure, reference numeral 1 denotes an octopus tube body made of hard plastic, with an air reservoir 2 formed in its upper middle portion, and an injection needle 3 attached to its tip. The rear end of the octopus tube main body 1 is branched into a Y-shape, and one branch 4 is connected to a body fluid or drug fluid guiding tube 6 made of soft plastic via a rubber tube 5. Further, the opening of the branching part 7 is closed with a rubber stopper 8, and serves as a mixed injection part for injecting other kinds of medical solutions.

Note that the branch portions 4 and 7 are connected by a reinforcing rib 9.

Next, an example of the use of the above embodiment will be explained. First, in FIG. 3, after puncturing the injection needle 3 into the patient's blood vessel,
The tip of the octopus tube body 1 and the branch parts 4 and 7 are taped with adhesive tape 10 so as to straddle them. In this case, the reinforcing ribs 9 may also be fixed with adhesive tape 10 instead of taping the branch portions or at the same time.

In addition, Figure 4 shows absorbent cotton 1 at the bottom of branch parts 4 and 7.
1 is placed and the injection needle 3 is angled in the puncturing direction. In this case, absorbent cotton 11
Since it is held down by the branch parts 4, 7 and the reinforcing rib 9, it does not move.

If other types of medicinal solutions are to be mixed in when necessary, the syringe needle of the set of medicinal solutions to be co-injected is inserted into the rubber stopper 8, and mixed into the octopus tube body through the branching portion 7.

(Effects) According to the present invention described above, since the rear end portion of the octopus tube body is branched in a Y-shape, the octopus tube body can be stably taped after being punctured with the injection needle. In addition, by making one of the branch parts a mixed injection part, it is possible to co-inject other types of medicine into the body of the Octopus tube in emergencies, etc., which has the effect of saving the trouble of replacing the transfusion set with a special transfusion set. can get.
