Abstract

The utility model discloses a curve vein transfusing pin, which belongs to the medical injecting pin head. The utility model comprises a hollow pin body, a wing-shaped handle, a connecting soft pipe, a pin plug and a belt piston; the hollow pin body is trapezoid round angle curved with the front part lower and the back part higher and the opening of the inclined surface of the pin head is in the same direction with the curve direction of the trapezoid. The pin head inclined surface of the utility model can not be covered by the vein wall completely and can ensure the smooth of the transfusing; the utility model reduces the chances of braking of the vein wall caused by the moving of the arm; the utility model releases the labor intensity of the caring workers and has a satisfying effect after the sample being tried in clinic.

Description

Bent build venoclysis needle

This utility model relates to a kind of syringe needle, is a yeast inoculation build venoclysis needle specifically.

The medical and clinical intravenous infusion syringe once was the ordinary straight body acupuncture head of pintle with an end.In recent years, generally use the hose connection pintle of stretched crown portion, and the venoclysis needle of stretched crown portion peripheral hardware symmetric double wing handle.Yet, in the infusion process of clinical practice, 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 and be inclined in endovascular needle point piercing blood vessel, cause subcutaneous hemorrhage, transfusion to disadvantage such as subcutaneous, often need the nurse when transfusion, constantly to adjust the angle of injection needle, raise as needle body root cushioning etc.

The purpose of this utility model is exactly in order to provide a kind of injection needle to thrust in the veins beneath the skin the smooth bent build venoclysis needle of transfusion, and therefore, this utility model is had any different in prior art.

This utility model designs by following technical scheme.

Bent build venoclysis needle comprises needle body, wing handle, connects flexible pipe, pintle, frenulum plug, it is characterized in that hollow needle body is low early and high after trapezoidal bending, and the same plane of pinpoint inclined plane opening and trapezoidal crooked position.

During use, pinpoint inclined plane upwards, syringe needle and skin are thrust by vein top or side, as see blood back into about the low-angle of 20 degree, prove that syringe needle gone into vein, can suitable again vein inserting needle to the needle body bending place.Then needle body is attached at skin, makes the parallel vein center place that places of needle body, use the immobilization with adhesive tape handle later on blood vessel.

Pinpoint inclined plane is unlikely after this utility model of design puncture is like this attached fully by blood vessel wall, ensures that transfusion is smooth, has reduced limbs and has moved the blood vessel wall that punctures that causes, and has alleviated nursing staff's labor intensity.

Below in conjunction with drawings and Examples this utility model is described in detail.

Accompanying drawing is this utility model surface structure sketch map.

Description of drawings: 1 curved needle body, 2 wing handles, 3 flexible pipes, 4 pintles, 5 frenulum plugs.

Bent build venoclysis needle comprises hollow needle body, wing handle, connects flexible pipe, pintle, frenulum plug, and hollow needle body is low early and high after trapezoidal bending, and the pinpoint inclined plane opening is consistent with trapezoidal bending direction.

The trapezoidal bending of hollow needle body is positioned at 1/3 place behind the needle body, and trapezoidal crooked ladder is high by 1.5 ± 0.5; Needle body parallel trapezoidal crooked alternate interior angle up and down is 140-150 °.Trapezoidal alternate interior angle circular bending slightly can reduce the chance of blood back blood clotting than the dead angle bending, and it is smooth to infuse.This utility model adopts the bent build venoclysis needle of 140 ° of alternate interior angles, through clinic trial, obtains satisfied practical function.

Claims

1. a yeast inoculation build venoclysis needle comprises hollow needle body, wing handle, connects flexible pipe, pintle, frenulum plug, it is characterized in that hollow needle body is low early and high after trapezoidal bending, and the pinpoint inclined plane opening is consistent with trapezoidal bending direction.

2. transfusion needle according to claim 1, the trapezoidal bending that it is characterized in that hollow needle body are positioned at 1/3 place behind the needle body.
