Description

Safety needle cover

This creation is related to medical equipment; in particular, it refers to a safety needle cover.

At present, the injection needles (also called butterfly needles) that are commonly used in medicine for injection include two wings and a needle. The needle is used to insert the skin, and the wings are used to fix the tape to the skin. After the injection, the medical staff should carefully cover the needle with the needle cover to avoid being hurt by the needle. However, during the process of covering the needle cover with the needle, if the needle cover is not aligned with the needle, the person may still be punctured.

In order to reduce the chance of medical staff being punctured by needles, some manufacturers have developed a needle sleeve that fits on the injection needle, such as the new patent number M552820. When the injection needle is used, the injection needle can be pushed out of the needle sleeve and used. After that, pull the injection needle back into the needle sleeve. Although this kind of needle sleeve can reduce the chance of personnel being punctured, but one end of this needle sleeve is open, if the wing of the injection needle comes out along the guide groove, the needle will still protrude from the needle sleeve, and there is a puncture wound The situation of personnel occurs.

In view of this, the purpose of this creation is to provide a safety needle cover, which can prevent the needle from protruding from the safety needle cover.

In order to achieve the above purpose, the present invention provides a safety needle cover for accommodating an injection needle, the injection needle has two wings and a needle; the safety needle cover is elongated, including: a main part, Two extension parts, at least one first buckle part and at least one second buckle part, wherein the two extension parts are connected to the main part and each of the extension parts extends along the long axis, and there is a formed between the two extension parts The accommodating space, and two guide grooves extending along the long axis are formed between the two extensions; the two guide grooves are respectively used for the two fins of the injection needle to pass through; the two extensions are pressed by external force to oppose Proximity; the at least one first buckle is provided on one of the extensions; the at least one second buckle is provided on the other extension and corresponds to at least one first buckle, the at least one second buckle For engaging with the at least one first buckling portion; wherein, when the two extending portions are relatively close by being pressed by an external force, the first buckling portion and the second buckling portion are engaged, so that the needle is restricted to the accommodating space in.

The effect of this creation is that the first buckle and the second buckle on the two extensions are engaged to effectively prevent the injection needle from escaping from the guide groove and causing the needle to protrude from the safety needle cover.

Please refer to FIG. 1 to FIG. 6 to create a safety needle cover 1 according to a preferred embodiment, which is used to accommodate an injection needle 100, and the injection needle 100 includes two wings 101 and a needle 102. The safety needle cover 1 is elongated and has a long axis. The safety needle cover 1 includes an integrally formed main portion 10, two extension portions 20, at least one first buckle portion 40 and at least one second buckle portion 50. among them:

The two ends of the main portion 10 communicate with each other. The two extension portions 20 are connected to the main portion 10. More specifically, each extension portion 20 has a fixed end 20a and a free end 20b. The fixed end 20a of each extension portion 20 is connected to one end of the main portion 10. Each extension 20 extends along the long axis. An accommodating space 30 is formed between the two extensions 20, and the accommodating space 30 is used for accommodating the injection needle 100 therein.

Two guide grooves 32 extending along the long axis are formed on both sides of the two extending portions 20 respectively, and the two guide grooves 32 are respectively used for the two fins 101 of the injection needle 100 to pass through. The two extensions 20 have elasticity and can be squeezed by external force to be relatively close. In this embodiment, each of the guide grooves 32 is open between the two free ends 20 b of the two extensions 20, so that the injection needle 100 can slide into or out of the safety needle cover 1. Each of the guide slots 32 has a first slot segment 322 and a second slot segment 324, the first slot segment 322 is located between the main portion 10 and the second slot segment 324, and the first slot segment 322 is between the two extensions 20 The width between the grooves is larger than the width between the second groove section 324 and the two extensions 20. At least one of the two extensions 20 has two notches 22, and each notch 22 communicates with the first slot segment 322 of each guide slot and is adjacent to the second slot segment 324 of each guide slot, and the notch 22 is located on the first slot segment 322 At the corner. In this embodiment, the two extensions 20 have two notches 22 respectively.

Each of the extensions 20 has an anti-slip structure 26, and the two anti-slip structures 26 are opposite to each other. In this embodiment, each of the anti-slip structures 26 is a plurality of ribs, and the ribs 262 are juxtaposed along the long axis. In addition, the two extensions 20 have different lengths in the longitudinal direction, that is, one is longer and the other is shorter. Each of the two extending portions 20 extends on the facing surface to form a blocking portion 24 that faces the accommodating space 30; when the two extending portions 20 are pressed and relatively close, the two blocking portions 24 The distance between them decreases.

The at least one first buckle portion 40 is disposed on one of the extension portions 20, the at least one second buckle portion 50 is disposed on the other extension portion 20 corresponding to the position of the first buckle portion 40, the second buckle portion 50 is provided Snap with the first buckle portion 40. In this embodiment, the number of the first buckle portion 40 and the second buckle portion 50 are two, respectively, and are respectively located on two opposite sides of the corresponding extension portion 20. The first buckle portion 40 is a buckle, and the second buckle portion 50 is a buckle slot. The first buckle portion 40 has a slope 402 on the side facing the second buckle portion 50. The first buckle portion 40 has a clamping edge 404 at a position away from the second buckling portion 50. The clamping edge 404 is along a direction away from the main portion 10 And inclined toward the direction away from the second buckle portion 50.

Please refer to FIG. 1 and FIG. 4, the longer extension 20 includes a gradual expansion section 206 on the opposite side from the main section 10. The gradual expansion section 206 has one end 206 a and the width of the gradual expansion section 206 is determined by The end portion 206a gradually expands in a direction away from the end portion 206a, and the gradually expanding section 206 is used to guide the fin 101 of the injection needle 100 when the injection needle 100 is retracted. In this embodiment, the outer peripheral surfaces on both sides of the gradually expanding section 206 extend in an arc. In practice, the outer peripheral surfaces on both sides of the gradually expanding section may also extend in a tapered shape.

In addition, in this embodiment, the extension 20 provided with the first buckle 40 includes a first segment 202 and a second segment 204, the first segment 202 is connected to the main portion 10, and the second segment 204 is provided with a first The buckle portion 40 and the width of the second section 204 is smaller than the width of the other extension portion 20.

5 and FIG. 6, when using the safety needle cover 1, first move the injection needle 100 so that the fin 101 is located in the first groove section 322 of the guide groove 32, and the needle 102 is also stored in the accommodating space 30. Then, the two extension portions 20 are pressed relatively to bring the two extension portions 20 close to each other, so that the first buckle portion 40 and the second buckle portion 50 are engaged, so that the needle of the injection needle 100 is restricted in the accommodating space 30. With the design of the gradually expanding section 206, the fin 101 of the injection needle 100 can enter the guide groove between the two extensions 20 along the gradually expanding section 206 during the process of the injection needle 100 being pulled back into the accommodating space 30 32, and during the movement of the fin 101 along the outer peripheral surface of the gradually expanding section 206, the fin 101 can be guided so that the two fins 101 smoothly enter the two guide grooves 32.

It is worth mentioning that, since the two extensions 20 have notches 22, the extension 20 can be deformed under pressure. The first buckle portion 40 abuts against the periphery of the second buckle portion 50 and enters the second buckle portion 50, so that the first buckle portion 40 can easily enter the second buckle portion 50. The buckle 404 of the first buckle 40 is inclined. After the first buckle 40 and the second buckle 50 are engaged, the buckle of the first buckle 40 can be flatly pressed against the groove of the second buckle 50 On the wall, this can effectively increase the strength of the engagement. In addition, after the distance between the stop portions 24 of the two extending portions 20 toward the accommodating space 30 is reduced, the position of the injection needle 100 in the accommodating space 30 can be further restricted, thereby reducing the chance of the injection needle 100 sliding out. The width of the second section 202 of the extension 20 provided with the first buckle 40 is small, so the second section 202 can be accommodated in another extension 20 and block the second groove section 324 of the guide slot 32 to avoid needles 102 slides out. The lengths of the two extension portions 20 in the longitudinal direction are different, which can reduce the chance of encountering the free ends 20b of the two extension portions 20 at the same time, causing the first buckle portion 40 and the second buckle portion 50 to separate.

According to the above, the safety needle cover of the present invention has the first buckle portion 40 and the second buckle portion 50 on the two extension portions 20 engaged with each other to effectively prevent the injection needle 100 from disengaging from the guide groove, causing the needle 102 to protrude from the safety needle Set of 1 dangers.
