Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a safety anti-puncture protective cover for an intravenous infusion needle. Background Art

[0002] Intravenous infusion utilizes atmospheric pressure and hydrostatic pressure to deliver large quantities of sterile fluids, electrolytes, and medications through the veins. It is a commonly used clinical medical procedure and requires the use of an intravenous needle. The needle is made of a stainless steel tubing bonded to a handle. A plastic hose is attached to the rear of the handle, which in turn connects to the needle hub. The tubing is fitted with a protective cap to maintain sterility before use. Medical personnel remove the cap before puncturing a vein. After the infusion is complete, the cap is easily lost due to its slender size, and its small inner diameter makes it difficult to re-cap the needle. Inserting a used intravenous needle into the protective sheath can easily expose the needle, which can cause needlestick injuries to medical personnel, posing a risk of disease transmission and infection.

[0003] In view of this, the inventor hopes to design a safety anti-puncture protective cover for intravenous infusion needles, which can prevent used intravenous infusion needles from causing needlestick injuries to medical staff. Utility Model Content

[0030] like Figures 1-6 As shown, this embodiment provides a safety anti-puncture protective cover for an intravenous infusion needle. The anti-puncture protective cover 1 includes a lower leaf 101 and an upper leaf 102 connected by a flexible member 103 at the front end.

[0031] In this embodiment, a first chute 104 is provided in the middle portion of the upper side of the lower leaf 101. Lugs 106 are provided on both sides of the first chute 104. A first limiting groove 107 is provided between the flexible member 103 and the lugs 106. A guide slope 108 is provided on the lugs 104 near the first limiting groove 107. A second limiting groove 109 is provided between the lugs 104 and the rear end of the lower leaf 101. A blocking vertical surface 110 is provided on the lugs 104 near the second limiting groove 109. An inwardly protruding lock catch 113 is provided on the rear end of the lower leaf 101.

[0032] In this embodiment, the intravenous infusion needle 2 includes a stainless steel needle tube 201, a needle handle 202, a plastic hose 203 and a butterfly wing 204. The stainless steel needle tube 201 is bonded and fixed to the needle handle 202. The rear of the needle handle 202 is connected to the plastic hose 203. The outer side of the needle handle 202 is provided with a butterfly wing 204.

[0033] In this embodiment, a second sliding groove 105 is provided in the middle portion of the lower side of the upper leaf 102 , and a locking groove 114 that cooperates with the locking buckle 113 is provided at the tail end of the upper leaf 102 .

[0034] In this embodiment, after the lower leaf 101 and the upper leaf 102 are assembled through the lock buckle 113 and the lock groove 114, the first slide groove 104 and the second slide groove 105 are connected to form a sliding channel that facilitates the sliding of the stainless steel needle tube 201, the needle handle 202 and the plastic hose 203.

[0035] In this embodiment, after the lower leaf 101 and the upper leaf 102 are assembled through the lock buckle 113 and the lock groove 114 , an opening is formed between the protruding plate 106 and the upper leaf 102 to facilitate the sliding of the butterfly wing 204 .

[0036] In this embodiment, the lower leaf 101 is provided with an anti-puncture wall 111 at the intersection of the first slide groove 104 and the first limiting groove 107. The design of the anti-puncture wall 111 is conducive to puncture-proofing the outer end of the stainless steel needle tube 201 when the intravenous infusion needle 2 slides backward for storage.

[0037] In this embodiment, the lower leaf 101 is provided with an eccentric step 112 at the intersection of the first slide groove 104 and the second limit groove 109.

The stainless steel needle tube 201 of the intravenous infusion needle 2 is exposed outside the front end of the anti-puncture protective sleeve 1 before use. The stainless steel needle tube 201 is equipped with a protective cap. The protective cap prevents the intravenous infusion needle 2 from being kept sterile before use. Medical personnel remove the protective cap when using it and then perform intravenous puncture and infusion into the human body. After the infusion is completed, the butterfly wing 204 is used to drive the intravenous infusion needle 2 to slide backward relative to the anti-puncture protective sleeve 1, so that the butterfly wing 204 moves from the first limiting groove 107 to the second limiting groove 109. The butterfly wing 204 is restricted in the second limiting groove 109. At this time, the stainless steel needle tube 201 is completely moved into the interior of the anti-puncture protective sleeve 1. In this way, the stainless steel needle tube 201 is effectively prevented from being exposed to the outside, and the stainless steel needle tube 201 will not cause needlestick injuries, eliminating the risk of disease transmission and infection.
