Abstract

PROBLEM TO BE SOLVED: To prevent the occurrence of a hindrance such as a vein is injured since the needle tip floats or the needle tip moves by protrusively arranging a blade part on both sides of a needle fixing part, and arranging a pedestal to hold the needle fixing part in its slant attitude at a specific angle under the blade part or the needle fixing part. SOLUTION: This needle is composed of an injection needle 1, a needle fixing part 2, a blade part 3, a pedestal 6, a tube 4 and an adapter 5, and the injection needle 1 is connected to one end of the needle fixing part 2, and the tube 4 and the adapter 5 are connected to the other end. The blade part 3 is also protrusively arranged on both ends of the needle fixing part 2, and the pedestal 6 is arranged under the needle fixing part 2. The pedestal 6 is arranged so that the needle fixing part 2 becomes a downward gradient toward the needle tip by holding the injection needle 1 in its slant attitude at a specific angle on the skin 7 when the blade part 3 is fixed on the skin 7 by using a sticking plaster.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an intravenous needle with a wing.

[0002]

2. Description of the Related Art In the treatment of diseases and the like, intravenous medication by infusion is widely used. However, even if the injection needle is pierced into the vein by long-term infusion, patients, doctors, and nurses can be used. An intravenous needle with a wing is used as a device devised so as not to impose a burden on the user. For example, as shown in a top view of FIG.
An injection needle 11 is fixed to one end of the device, and a tube 14 with an adapter 15 is connected to the other end of the needle fixing portion 12.
Further, wing portions 13 are provided on both sides of the needle fixing portion 12.

[0003] When administering medication using the above-mentioned winged intravenous needle, the wings 13 on both sides are folded up and picked up.
As shown in FIG. 6, after piercing the needle tip of the injection needle 11 into the vein 16, after confirming that blood flows into the tube 14, the wing 13 is opened, and the wing 13 is attached to a bandage (not shown).
Drugs are fixed and fixed.

[0004] However, this winged static needle has a wing 1
When the band 3 is fixed on the skin 17 using a bandage, if the bandage is excessively restrained, the needle point of the injection needle 11 rises, and the needle point adheres to the wall of the vein 16 and the medicine may not be smoothly administered. there were. If the bandage is too weak, vein 1
In 6, the needle tip moved and the inside of the vein 16 was damaged, so that pain and internal bleeding sometimes occurred. For this reason, there is a problem that skill is required for adjusting the force when the wing portion 13 is fixed with the adhesive plaster. Further, it is necessary to prepare a bandage cut into an appropriate length in advance prior to administration, which is troublesome.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to raise the needle tip or move the needle tip even if the tip of the injection needle is inserted into a vein and then fixed using a bandage. An object of the present invention is to provide a winged intravenous needle which does not cause any trouble such as damaging a vein.

[0006]

The winged intravenous needle of the present invention comprises:
In a winged static injection needle in which an injection needle is fixed to one end of a needle fixing portion and a tube is connected to the other end of the needle fixing portion, wings project from both sides of the needle fixing portion, and the wing or the needle A pedestal for holding the needle fixing portion at a fixed angle is provided below the fixing portion.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION A winged intravenous needle of the present invention has an injection needle 1, a needle fixing part 2, a wing part 3, as shown in a bottom view in FIG.
It comprises a pedestal 6, a tube 4 and an upper 5. One end of the needle fixing part 2 is connected to the injection needle 1, and the other end is connected to the tube 4 and the upper 5. Further, wing portions 3 are provided on both sides of the needle fixing portion 2, and a pedestal 6 is provided below the needle fixing portion 2.

[0008] The winged intravenous needle is picked up by folding the wing portion 3 at the time of use, and as shown in FIG. The wings 3 are fixed on the skin 7 using (not shown). The pedestal 6 holds the injection needle 1 at a fixed angle on the skin 7 when the wing portion 3 is fixed on the skin 7 using a plaster, and the needle fixing portion 2 is positioned on the needle tip side. It is provided so as to have a downward slope.

When the injection needle 1 is pierced into the vein 8, the pedestal 6 moves the injection needle 1 10 to the skin 7 surface.
It is preferable to be provided so as to be inclined and held at an angle of 40 degrees. When the angle is less than 10 degrees, the needle tip of the injection needle 1 is easily lifted when fixed with a bandage, and the angle
Exceeding the degree makes it difficult to hold the needle tip in the vein 8.

The wings 3 and the pedestal 6 are preferably integrally formed by injection molding or the like using the same material, but may be formed separately and then joined to be integrated. Examples of the material used for the wing portion 3 and the pedestal 6 include polyethylene, polyethylene terephthalate, ethylene-vinyl acetate copolymer, polyvinyl chloride, styrene-isoprene-styrene copolymer, polyethylene foam, polyethylene terephthalate, and the like. However, if the material is flexible and does not hurt the skin when fixed,
There is no particular limitation.

The pedestal 6 may be provided on the lower surface of the wing 3 as shown in FIG. 3 as long as the injection needle 1 can be held at the above angle.

Further, as shown in FIG. 4, an adhesive portion 9 applied with an adhesive may be provided on the pedestal 6 surface. It is preferable that the adhesive section 9 is protected by laminating release paper until use. By providing such an adhesive portion 9, the trouble of using a plaster can be omitted.
As the release paper, for example, a polyethylene terephthalate film subjected to a silicone release treatment is used.

Further, a cushion material (not shown) may be arranged between the pedestal 6 and the adhesive portion 9. As the cushion material, polyethylene foam, ethylene-
The sheet is not particularly limited as long as it is a sheet of a resin foam having flexibility and cushioning properties, such as a foam of a vinyl acetate copolymer. By providing such a cushion material,
The adhesion to the skin is improved, and the injection needle 1 can follow even if it moves slightly.

[0014]

The winged intravenous needle of the present invention has the above-mentioned construction, and is fixed to the wing or the needle when the needle tip of the injection needle is pierced into a vein and then fixed using a bandage. The pedestal provided at the lower part of the section allows the injection needle to be held at a certain angle while being inclined, so that there is no hindrance such as the needle tip being lifted or the needle tip moving and damaging the vein.
