Referring to fig. 1 to 4, the present embodiment provides a safety infusion needle, which includes a needle handle 12, a needle head 11, a wing 13, a needle cap 2 and a drip-proof device 3.
One end of the needle head 11 is fixed on the needle handle 12, the other end of the needle head 11 is a tip end, the wing 13 is fixed on the needle handle 12, the needle cap 2 adopts a silicone tube, the tube diameter of the needle cap 2 needs to be larger than the diameter or thickness of the needle handle 12, so as to ensure that the needle handle 12 can slide in the needle cap 2, the needle cap 2 is sleeved on the needle head 11, the needle cap 2 is provided with a chute 21 along the length direction of the needle cap, the wing 13 of the infusion needle is positioned in the chute 21, and when the needle cap 2 is driven to slide along the length direction of the needle head 11, the wing 13 can slide in the chute 21. In the prior art, the sliding groove 21 is an open sliding groove 21 with one open end and the other closed end, and the needle cap 2 is easy to fall off from the needle 11 during use, so as to avoid the needle cap 2 falling off from the needle 11. In this embodiment, the sliding slot 21 includes a free sliding section 211 and a positioning section 212, the free sliding section 211 is communicated with the positioning section 212, the width of the slot of the free sliding section 211 is greater than the width of the slot of the positioning section 212, the width of the slot of the free sliding section 211 is based on the free sliding of the tab 13, the width of the tab 13 is greater than the width of the slot of the positioning section 212, the width of the slot of the positioning section 212 is based on the fact that the tab 13 cannot slide freely in the positioning section 212 and needs to be pulled gently, when the tab 13 is in the positioning section 212, it is ensured that the positioning section 212 can clamp the tab 13, the positions of the pack 2 and the needle 11 are relatively fixed, the pack 2 is prevented from sliding freely, and the needle tip is prevented from being exposed accidentally when the needle tip is not required to be exposed. It should be noted that, when the needle cap 2 is in the initial state of non-use, the fins 13 are on the positioning section 212 of the sliding groove 21; when the transfusion is performed, the medical staff slides the needle cap 2 along the needle point to the direction of the needle handle 12, and the wing piece 13 slides from the positioning section 212 to the free sliding section 211 to expose the needle point; after the transfusion is withdrawn, the medical staff slides the needle cap 2 along the needle handle 12 towards the needle point, the wing piece 13 slides from the free sliding section 211 to the positioning section 212, and when the needle cap 2 completely covers the needle 11, the wing piece 13 is positioned in the positioning section 212 again.
The drip-proof device 3 is arranged at one end of the needle cap 2, the drip-proof device 3 is positioned at one end of the needle point of the needle head 11, when the transfusion is performed, the medical staff slides the needle cap 2 along the needle point to the direction of the needle handle 12, and the needle head 11 pierces the drip-proof device 3 until the drip-proof device is completely exposed. In this embodiment, the drip-proof device 3 includes the easy-to-pierce rubber seat 31 and the water-absorbing layer 32, the easy-to-pierce rubber seat 31 is a silica gel rubber seat, or other rubber seats which meet medical conditions and have elasticity are adopted, the silica gel rubber seat is fixed at the port of the needle cap 2 or fixed at the inner wall of the needle cap 2, in this embodiment, the silica gel rubber seat is fixed at the inner wall of the needle cap 2, and the easy-to-pierce rubber seat 31 is a funnel-shaped rubber seat, the inner concave surface of the funnel-shaped rubber seat faces the needle 11, by adopting the funnel-shaped rubber seat, the bonding area of the water-absorbing layer 32 can be increased, the water-absorbing area of the water-absorbing layer 32 is also increased, and the water-absorbing effect is improved. And the easy-puncture rubber seat 31 is provided with a first needle-walking hole 33, so that the needle 11 can conveniently pass through the first needle-walking hole 33, and the needle 11 is prevented from being dulled when the needle 11 punctures the easy-puncture rubber seat 31. The water absorbing layer 32 is adhered to the surface of the rubber seat 31, and the water absorbing layer 32 faces the needle 11, in this embodiment, the water absorbing layer 32 is a medical absorbent cotton sheet. And a second needle-walking hole 34 is arranged on the water-absorbing layer 32, so that the needle 11 can penetrate out of the second needle-walking hole 34, the needle 11 can be prevented from being dulled when the needle 11 pierces the water-absorbing layer 32, and the first needle-walking hole and the second needle-walking hole 34 are arranged concentrically. When the infusion is punctured, the medical staff slides the needle cap 2 along the needle point to the direction of the needle handle 12, the needle point sequentially punctures the water absorbing layer 32 and the easy puncture rubber seat 31 and is finally exposed outside the needle cap 2 to expose the needle point; after the infusion is pulled out the needle, medical personnel slide needle cap 2 along needle handle 12 to the direction of needle point, and needle cap 2 wraps up syringe needle 11 in needle cap 2 again, and when needle cap 2 wrapped up syringe needle 11 completely, fin 13 was lain in the section of location 212 again, and at this moment, the remaining liquid medicine that syringe needle 11 drips and spills is absorbed by layer 32 that absorbs water to reach the purpose of avoiding remaining liquid medicine to leak to the environment. Although the easy-to-puncture rubber seat 31 and the water absorption layer 32 have the needle passing holes, the needle passing holes are small, and the residual medicine liquid drop leakage is small, so that the medicine liquid leaked to the outside of the needle cap 2 can be ignored.
In the embodiment, the anti-dripping device is arranged on the needle cap, and the residual liquid medicine leaked by the needle head is absorbed by the anti-dripping device so as to achieve the purpose of preventing the residual liquid medicine from leaking to the environment.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
