Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a needle cover for a syringe, and particularly to handle a used syringe more safely.
[0002]
[Prior art]
A syringe used in the medical field has a cover attached to the needle of the syringe from the viewpoint of ensuring safety during handling.
[0003]
By the way, the conventional needle cover is a cap type having a single opening for inserting a needle, and there is a possibility that a hand or a finger may be damaged by the needle tip when the needle cover is attached to the needle. . Further, this type of needle cover is troublesome in itself, and the burden on the operator (especially the mental burden) is large, and improvement is required.
[0004]
[Problems to be solved by the invention]
The subject of this invention exists in the place which proposes the novel needle cover which can store an injection needle safely and simply after use of a syringe.
[0005]
[Means for Solving the Problems]
The present invention is a cover for covering at least the distal end region of a needle of a syringe, a base fixed to a syringe of a syringe or detachably fitted and held, and swingable to the base via a hinge And a cover body having a recessed space for storing at least the tip end region of the needle by being connected and raised, and held in the cover body so as to be able to be folded back along the mutually opposing edges of the recessed space. A pair of lids for closing each part of the recess space that houses at least the tip region of the needle by folding each other with the folding groove as a starting point in the state, and one tip of the lid The needle cover for a syringe is provided with a projection on the other end of the lid, and has an opening that fits the projection and connects the lids to each other.
[0007]
The base is particularly advantageously adapted to have a circular cross-section surrounding the entire circumference of the syringe barrel or a C-shaped cross-section surrounding at least half the circumference of the syringe barrel.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described more specifically with reference to the drawings.
[0009]
1 (a) to (c) and FIG. 2 show one embodiment of a needle cover according to the present invention, FIG. 1 (a) is a front view, FIG. 1 (b) is a side view, FIG. 1 (c) is a plan view, and FIG. 2 is an external perspective view thereof.
[0010]
In the figure, reference numeral 1 denotes a base shown as an example of a C-shaped cross section surrounding a syringe barrel, and reference numeral 2 denotes a cover body that is swingably connected to the base 1 via a hinge h. The cover main body 2 has a recessed space 2a for storing the needle by its pulling up.
[0011]
Reference numerals 3 and 4 are lids for closing the recessed space 2a in a state in which the needle is stored. The lids 3 and 4 are held so as to be folded back along the edge of the recessed space 2a. Are folded back with the folding groove S as a starting point, the tip portions of the lid bodies 3 and 4 are brought into contact with each other to close the recessed space 2a.
[0012]
Further, in the figure, 5 is a convex portion provided integrally with the base 1 on the back surface of the base 1, 6 is an opening provided in the cover body 2, and 7a and 7b lock the injection needle to the wall surface of the concave space 2a. It is an elastic tongue piece.
[0013]
FIG. 3 shows a state in which the needle cover configured as described above is attached to the syringe tip of the syringe. In FIG. 3, the phantom lines indicate the posture of the cover body 1 before use (during use) of the syringe. In this state, the convex portion 5 provided on the base 1 is fitted into the opening 6 of the cover body 2. Thus, the cover body 2 does not swing easily.
[0014]
After the use of the syringe, the injection needle is housed in the recessed space 2a only by an action that causes the cover body 2 to start from the hinge h, and is locked to the wall surface of the recessed space 2a by the elastic tongues 7a and 7b. Then, as shown in FIG. 4, the concave portions 2a are closed by folding back the lid bodies 3 and 4 and abutting the end portions thereof.
[0015]
The needle cover shown in FIG. 1 is shown as having a base 1 having a C-shaped cross section, but the base 1 may have a circular cross section as shown in FIG. Moreover, it is not essential that the base 1 be detachable from the syringe, and once the base 1 is attached to the syringe, the base 1 may be fixed so as not to be removable.
[0016]
Further, as shown in FIG. 6, the cover main body 2 can be provided with an engaging means 8 that firmly holds the posture with respect to the base 1 in an upright posture in which the injection needle is stored, thereby further enhancing the safety. Rise.
[0017]
The needle cover can be manufactured by injection molding a synthetic resin, but the material and molding method are not particularly limited.
[0018]
【The invention's effect】
According to the present invention, the cover can be safely and easily attached to the needle of the used syringe.
[0019]
Further, according to the present invention, since the base is fixed to the syringe of the syringe or is detachable, it can be applied to any existing syringe, which contributes to improvement of safety in the medical field.
