Detailed Description
The safety syringe needle facilitating pressing according to the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
In the description of the present invention, it should be noted that the directions or positional relationships indicated as the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., appear based on the directions or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention.
Referring to fig. 1-3, the safety injection needle beneficial to pressing provided by the embodiment includes a pintle 1 and a needle stem 2, and further includes a safety fastener 3 for preventing a needle stick injury, and a pressing sheet 4 for pressing a needle hole to stop bleeding is bonded to the bottom of the safety fastener 3; fixing belts 41 for fixing the pressing sheet 4 are fixedly connected to both sides of the pressing sheet 4; the safety fastener 3 and the pressing sheet 4 are sleeved on the needle stem 2 in parallel, and the safety fastener 3 can be fixed at the tip of the needle stem 2 and cover the needle stem 2 after the needle stem 2 is pulled out.
Further, the safety fastener 3 comprises a protective cover 31, the bottom wall of the protective cover 31 is bonded with the pressing sheet 4, sleeves 32 are symmetrically arranged in the protective cover 31, one end of each sleeve 32 is fixedly connected to the inner side wall of the protective cover 31, and the other end of each sleeve 32 extends along the radial direction of the protective cover 31; a movable rod 33 is arranged in the sleeve 32, one end of the movable rod 33 is elastically connected with the inner side wall of the protective cover 31 through a spring 34, and the other end of the movable rod 33 extends out of the sleeve 32 and is fixedly connected with a hoop 35; the tip of the needle stalk 2 is provided with a clamping groove 21 which is clamped and matched with the hoop 35. When the needle stalk 2 is extracted, because the needle stalk 2 is more smooth, the frictional force of staple bolt 35 and needle stalk 2 is less, protection casing 31 can be fixed on the needle eye along with pressing tablet 4 under the effect of pressing tablet 4 adhesion force, when the needle stalk 2 is extracted to draw-in groove 21 and staple bolt 35 joint, staple bolt 35 hugs closely needle stalk 2 most advanced under the effect of spring 34 elasticity for protection casing 31 fixes at needle stalk 2 most advanced and covers it, thereby make protection casing 31 and pressing tablet 4 separate and continue to extract along with needle stalk 2, prevent the needle stick injury of follow-up operation.
Furthermore, the hoop 35 can be set to be semicircular and have the same diameter as the needle stalk 2, so that the two hoops 35 can surround the needle stalk 2 to form a circle, and the fixing effect of the hoop 35 can be improved; the diameter of movable rod 33 slightly is less than the internal diameter of sleeve 32, makes movable rod 33 be difficult to take place to rock in sleeve 32, and movable rod 33 stretches out the outer one end fixed connection of sleeve 32 in addition and at the convex surface center of staple bolt 35, can prevent that staple bolt 35 from sliding.
Further, draw-in groove 21 is for seting up the annular groove on 2 most advanced global of needle stalk, and the width of annular groove is the same with staple bolt 35's height, and the degree of depth of annular groove equals staple bolt 35's thickness for staple bolt 35 can imbed completely in the annular groove, prevents to lock and takes place to rock behind the fixed protection casing 31.
Further, in order to solve the problem that the safety fastener 3 is easy to move along the needle stem 2 and is inconvenient to use, the opening end of the protective cover 31 can be connected with the pintle 1 through threads, and when the safety fastener is not used, the protective cover 31 is screwed down to fix the safety fastener 3 on the pintle 1.
Furthermore, after the tip of the needle stem 2 is pulled out, the needle stem 2 is easily inclined to deviate from the axis of the protective cover 31, so that the hoop 35 is not corresponding to the position of the clamping groove 21 and is difficult to fix. Based on this, can set up the thickness that 31 diapires of protection casing are greater than the length of 2 most advanced tip of needle stalk for 2 most advanced back of extracting of needle stalk, the pinhole on the staple bolt 35 diapire can play the guide effect to needle stalk 2, until staple bolt 35 and draw-in groove 21 joint are fixed with needle stalk 2, and at this moment, the pinhole on staple bolt 35 diapire is accomodate to 2 most advanced of needle stalk.
Further, in order to prevent behind the fixed pressing piece 4, ooze in the easy pinhole through pressing piece 4 of blood, can set up the top of pressing piece 4 into being made by medical silica gel material, so, the back is extracted to 2 pointed ends of needle stalk, because medical silica gel texture has elasticity, can reply automatically and plug up the pinhole, and medical silica gel is nontoxic moreover, does not have the stimulation to human tissue, and aseptic gauze has been laid to 4 bottoms of pressing piece simultaneously for it is safer to press hemostasis.
Further, the fixing band 41 is an elastic non-woven fabric tape with a single-side coating, which is made of a porous, highly air-permeable brown elastic multi-layer polyurethane or synthetic rubber non-woven fabric, one side of which is coated with a pressure-sensitive adhesive, and the pressure-sensitive adhesive is covered with release paper. The single-side coating elastic non-woven fabric adhesive tape is suitable for human skin, can improve the comfort level, and when in use, the release paper is torn off, and one side coated with the pressure-sensitive adhesive is bonded on the skin near the needle eye, so that the pressing sheet 4 is fixed.
The utility model discloses a working process and principle:
after the injection is finished, the pressing sheet 4 is fixed on the needle eye through the fixing belt 41 and keeps a pressing state; then the fixing band 41 is pressed by fingers to pull out the needle stalk 2, in the process of pulling out the needle stalk 2, the safety fastener 3 is fixed on the needle eye along with the pressing sheet 4 under the action of the adhesive force of the pressing sheet 4, when the needle stalk 2 is pulled out to the state that the clamping groove 21 is clamped with the hoop 35, the hoop 35 clasps the tip end of the needle stalk 2 under the action of the elastic force of the spring 34, so that the protective cover 31 can be fixed at the tip end of the needle stalk 2 and covers the tip end; finally, the protective cover 31 is separated from the pressing sheet 4 and is continuously pulled out along with the needle stalk 2, so that the needle injury in the subsequent operation is prevented.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
