た。2. Description of the Related Art As is well known, a needle cap to be attached to a medical needle such as a winged needle or a blood sampling needle is formed in a cylindrical shape or a tapered cylindrical shape, Used to protect and recap for safety when disposing of the medical needle. However, as a problem until discarding these needle caps, when attaching the needle cap to the needle again, the needle of the operator is accidentally stabbed, or if the needle cap is discarded without attaching the needle cap, it is a needle with blood attached, There was a risk that the worker would accidentally stab during work. Also US Patent 5,112,311
No. 5,433,703, 5,562,636,
No. 5,562,637 has slits for fixing both wings of a winged needle on both sides of the needle cover, and after using the needle, slides and fixes both wings according to the position and shape of the slit. An invention has been proposed in which a needle is stored in a needle cover.
However, also in these inventions, (1) ease of assembly and stability when the needle cover is attached to the winged needle,
(2) Operability when puncturing a patient with a winged needle having a needle cover,
(3) There is room for further improvement in operability when the needle cover is capped after using the needle. Japanese Patent Application 2000-15
No. 4126, the applicant has proposed that wing-shaped stoppers project on both sides of the abdomen of the needle cover, the used winged needles are stored in the needle cover, and then both winged portions of the winged needles are bent upward. Although both wings are crossed with the stopper and locked, the winged needle does not project from the needle cover,
When pulling the tube close to the needle base of the winged needle and putting the winged needle in the needle cover, both wings must be bent upward with the hands pulling the tube released. Therefore, there is a concern that some users may dispose without using the stopper function by releasing their hands from the tube, and the needle of the winged needle protrudes again from the needle cover to expose the needle tip, which may cause medical problems during disposal. There is concern that workers and waste companies may accidentally stab during work. Further, it has been pointed out that the operation is troublesome because both wings of the winged needle must be bent upward and locked to the stopper. Therefore, the present inventor has earnestly studied to solve the above problems, and as a result, arrived at the following invention.

As shown in (b), lightly pinch both sides of the convex portion 7c with the thumb and forefinger of the left hand (right hand), and sandwich the both wings of the wing portion 14 with the thumb and forefinger of the right hand (left hand) and stack both wings upward. To match. As in (c), the needle cap 16 is removed and the needle 12 of the winged needle 10 is exposed from the needle cover 1. Wing 1 with the thumb and index finger of the right hand (left hand) as in (d).
Position the body with both wings of 4 facing upwards and stack them, and puncture the patient's arm or the like. After puncturing the patient's arm or the like as in (e), the wing portion 14 is returned to the horizontal position and the wing portion 14 and the skin are fixed with tape so that the puncture site does not move. Needle 12 of winged needle 1A with a needle cover punctured as in (f)
When removing the puncture from the puncture part, remove the tape, put a cotton swab on the puncture part, press the puncture part from above the sterilized cotton with the ring finger of the left hand (right hand), and remove the middle finger and the index finger from the convex part 7a and the convex part 7b or convex part 7b. The protrusions 7a and 7b are attached to the wall surface between the portion 7b and the protrusion 7c so that the protrusions 7a and 7b hang on their fingertips. For example, as shown in FIG. 2C, pull the tube 15 near the rear portion 4 with the right hand (left hand). After the winged needle 10 is housed in the needle cover 10, the tube 15 is pulled up and raised, and fixed in the groove 22 through the space between the protrusions 23a and 23b.

1A is a cross-sectional view, and FIG. 9 is a perspective view showing in time series an example of how to use the winged needle 31A with a needle cover. Figure 8
9A corresponds to FIG. 9A, and FIG. 8B corresponds to FIG. 9E. The needle cover with cap 81 of the present invention is one in which the cap 28 is integrally formed on the tubular tip of the front portion 2 of the needle cover 1 via a thin portion 28a. In order to easily separate the integrally formed cap 28, a pair of ribs (not shown) may be provided on the outer periphery of the cap 28 at least in the symmetrical direction. Like the capped needle cover 71, the capped needle cover 81 also has a winged needle 1.
It is possible to assemble the winged needle 31A with a needle cover by mounting it on 0. The winged needle 31A with a needle cover is used in the same manner as the winged needle 21A with a needle cover as shown in FIGS. 9 (a) to 9 (f), but the winged needle 31A with a needle cover is shown in FIG. 9 (c). Thus, the cap 28 is different from the winged needle 21A with a needle cover in that the cap 28 is exposed by being cut from the thin portion 28a.

危険を防ぐことができる。In the needle cover, the needle cover with a cap, and the winged needle with a needle cover of the present invention, the winged needle 10 is replaced by the needle cover 1 and the capped needle cover 71.
The operability is good because the needle can be capped by simply sliding it linearly in the front two directions of (81) or in the opposite direction. Since the convex portions 7a, 7b, 7c are formed on the outer surfaces of the needle cover 1 and the capped needle cover 71 (81), they can be easily fixed during work and the winged needle 10 can be easily slid. Since the needle cover with cap 81 can protect the needle and slide the needle cover simultaneously with one component, the number of components can be reduced and the operability is improved. (A) Needle cover 1 and needle cover with cap 71 (8
1) and the winged needle 10 are assembled, the needle cover 1 and the capped needle cover 71 (81) and the winged needle 10 can be fixed so as not to move, and (b) the needle cap 16 (caps 18, 28) is used. The needle 12 can be easily exposed from the needle cover 1 and the capped needle cover 71 (81) by removing the needle, and (c) the winged needle 10 is in front of the needle cover 1 and the capped needle cover 71 (81) after use. The tube 15 of the winged needle 10 can be fixed so as not to move in the direction of the section 2.
The groove 2 formed from the upper portion of the rear portion 4 of 1) to the convex portion 7c
It is possible to prevent the needle 12 from being exposed by sandwiching and fixing the needle 12 to the needle 2 via the protrusions 23a and 23b, and there is a risk that a medical worker or a waste company at the time of disposal may accidentally stab it during work. Can be prevented.
