Abstract
The utility model discloses a bending vein syringe needle which comprises a hollow needle body, wherein the root part of the hollow needle body is connected with a needle tube by a flexible pipe; the root part of the hollow needle body is symmetrically and outwards provided with two wing-shaped handles; a filling opening of the needle tube is provided with a lacing plug. The utility model has the essential proposal that the hollow needle body forms a trapezoidal bending shape with the low front part and the high rear part; a needle tip bevel opening and the trapezoidal bending site are in the same plane. When the utility model is used, a needle tip bevel is upward, a needle head and a muscle body form the angle of 20DEG or so, the needle is punctured front the upper part of the lateral part of a vein, in case blood return is watched, the needle head is proved to be penetrated into the vein and the needle can be penetrated along the vein again to the bending site of the needle body. Then, the needle is attached to the muscle body, the needle body and a blood vessel are arranged at the center site of the vein in parallel and the handles are fixed by a rubberized fabric. After the utility model is punctured, the needle tip bevel can not be completely attached by the blood vessel wall and the utility model ensures smooth transfusion and reduces the probability of the puncture of the blood vessel wall caused by the movement of limbs. Clinical use proves that the utility model has the advantages of obvious effect and convenient operation, reduces the pain of patients and can be widely used for clinic.
Description
The novel transfusion needle technical field that belongs to of this use of technical field relates to a kind of medical infusion pin, is specifically related to a kind of bending venoclysis needle.
Background technology is present, and the medical vein infusion needle is the stretched syringe needle.By hose connection needle tubing, stretched crown portion symmetry peripheral hardware double-vane shape handle constitutes the venoclysis needle of clinical usefulness by stretched crown portion.In the clinical practice infusion process, find because vein is buried in subcutaneous, often be close to blood vessel wall because of the needle point opening part of injection needle set, it is not smooth to make it venous transfusion, or limbs have activity slightly, will make to be inclined in endovascular needle point piercing blood vessel, cause subcutaneous hemorrhage, infuse in the subcutaneous disadvantages such as hematoma that cause.When needing the nurse to infuse, raise the angle of adjusting infusion needle, inconvenient operation at needle body root cushioning.
The novel purpose of this use of summary of the invention provides a kind of infusion needle and thrusts the smooth bending venoclysis needle of veins beneath the skin transfusion, to overcome the deficiencies in the prior art.
For achieving the above object, this utility model bending venoclysis needle, comprise hollow needle body, the root of hollow needle body is by hose connection needle tubing, the root symmetry peripheral hardware double-vane shape handle of hollow needle body, the needle tubing inlet is provided with the frenulum plug, and its main points are that hollow needle body is low early and high after trapezoidal bending, and pinpoint inclined plane opening and trapezoidal bending place are positioned at same plane.
During use, pinpoint inclined plane up, syringe needle and human body are thrust by vein top or side, as see blood back into about 20 ° angle, proves that syringe needle gone into vein, can suitable again vein inserting needle to the needle body bending place.Then, needle body is attached at human body, makes the parallel vein center place that places of needle body, reuse immobilization with adhesive tape handle with blood vessel.
Pinpoint inclined plane is unlikely after this utility model puncture is attached fully by blood vessel wall, ensures that transfusion is smooth, has reduced limbs and has moved the probability that causes blood vessel wall to pierce through, and has alleviated nursing staff's labor intensity.
Appended drawings is this utility model structural representation.
Among the figure 1, the hollow needle body 2 of bending, wing handle 3, flexible pipe 4, needle tubing 5, frenulum plug
The specific embodiment with reference to the accompanying drawings, this utility model bending venoclysis needle, comprise hollow needle body 1, the root of hollow needle body 1 connects needle tubing 4 by flexible pipe 3, the root symmetry peripheral hardware double-vane shape handle 2 of hollow needle body 1, needle tubing 4 inlets are provided with frenulum plug 5, and hollow needle body 1 is low early and high after trapezoidal bending, and pinpoint inclined plane opening and trapezoidal bending place are positioned at same plane.
The trapezoidal bending place of hollow needle body 1 is positioned at 1/3 position behind the needle body, the high 1.5+0.5mm of trapezoidal bending place ladder; Needle body parallel trapezoidal bending place alternate interior angle up and down is 140-150 °.Trapezoidal alternate interior angle corner bevelling folding slightly can reduce the chance of blood back blood clotting, and it is smooth to infuse.This utility model adopts the bending venoclysis needle of 140 ° of alternate interior angles, and clinical use proves that effect is obvious, both has been convenient to operation, has reduced patient's misery again, can be widely used in clinical.
