Abstract

A vein puncturing needle used for magnetic resonance comprises a needlepoint, a reversed needle hole, a needle rod body, a fixed wing, a handle and a needle tail, wherein, the needle rod body is a main component, the entire needle rod body is a hollow cylinder, the beveling-type needlepoint is arranged at the front end of the needle rod body, and the reversed needle hole is formed on the needle rod body at the rear part of an inclined opening of the needlepoint. The needle tail is at the tail end of the needle rod body, the fixed wing is arranged in the slightly-forward position of the needle tail, and the handle is arranged in the central position of the fixed wing. When particularly in use, after the handle held in hand conducts puncture, the fixed wing and the handle are pasted on the skin of the patient with the adhesive tape, so as to prevent the needlepoint from upwardly floating and prevent the needle head from vibrating. The utility model has the advantages that the entire structure is simple, the operation and the application are convenient, the needle is fixed through the adhesive tape, and the needle is stable and reliable, so as to better prevent the needlepoint from upwardly floating and prevent the needle head from vibrating, in the event of the condition that the front needle hole of the needlepoint is sealed by the vessel wall due to the upwardly floating of the needlepoint, the reversed needle hole still can perform the transfusion of liquid medicine, and the magnetic resonance examination can be normally ensured.

Description

The venipuncture needle that is used for magnetic resonance

Technical field:

This utility model relates to medical apparatus and instruments, relates in particular to the venipuncture needle that is used for magnetic resonance.

Background technology:

According to prior art, when doing the magnetic resonance venipuncture, the puncture needle that uses is exactly common venipuncture needle, use the puncture needle of this common form, piercing needle floats phenomenon on taking place easily in magnetic resonance examination, and pinpoint inclined plane is stopped up by blood vessel wall, cause transfusion to be obstructed, syringe needle is difficult for stablizing besides, and syringe needle easily forms vibration in blood vessel, blood vessel structure is damaged.

The utility model content:

The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of venipuncture needle that is used for magnetic resonance is provided, and this puncture needle is convenient fixing, the transfusion generation of phenomenon of being obstructed in the time of can effectively preventing to float on the needle point.

The venipuncture needle that is used for magnetic resonance described in the utility model, including needle point, reverse pin hole, shank body, fixed-wing, handle and backshank forms, said shank body is a main component of the present utility model, whole hollow cylinder, the front end of shank body is provided with the needle point of inclined cutout, needle point should be sharp, conveniently to thrust.On the shank body of the back of needle point diagonal cut joint, be provided with the logical reverse pin hole of endoporus outward.The end of shank body is a backshank of the present utility model, on the forward slightly position of backshank, is provided with fixed-wing, in the center of said fixed-wing, is provided with the handle that conveniently grips.During concrete the use, hands is handled knob after handle implements puncture, sticking on fixed-wing and the handle on patient's the skin with adhesive plaster, with prevent needle point on float vibration with syringe needle.Just in case float on taking place owing to needle point and make the preceding pin hole of needle tip by the situation of blood vessel wall shutoff, reverse pin hole still can carry out the infusion of liquid, thus the venous transfusion when being more suitable for magnetic resonance examination.

The venipuncture needle that is used for magnetic resonance described in the utility model, overall structure is simple, easy for operation, use immobilization with adhesive tape, reliable and stable, can prevent preferably needle point on float vibration with syringe needle, and just in case float on taking place owing to needle point make that the preceding pin hole of needle tip is by the situation of blood vessel wall shutoff under, oppositely pin hole still can carry out the infusion of liquid, guarantees normally carrying out of magnetic resonance examination.

The specific embodiment:

Referring now to accompanying drawing, be described as follows in conjunction with the embodiments: the venipuncture needle that is used for magnetic resonance described in the utility model, including needle point 1, reverse pin hole 2, shank body 3, fixed-wing 4, handle 5 and backshank 6 forms, said shank body 3 is main components of the present utility model, whole hollow cylinder, the front end of shank body 3 is provided with the needle point 1 of inclined cutout, and needle point 1 should be sharp, conveniently to thrust.On the back of needle point diagonal cut joint shank body 3, be provided with the logical reverse pin hole 2 of endoporus outward.The end of shank body 3 is backshanks 6 of the present utility model, on the forward slightly position of backshank 6, is provided with fixed-wing 4, in the center of said fixed-wing 4, is provided with the handle 5 that conveniently grips.During concrete the use, hands is handled knob after handle 5 implements puncture, stick on patient's the skin on fixed-wing 4 and handle 5 with adhesive plaster, with prevent needle point 1 on float vibration with syringe needle.Just in case float on taking place owing to needle point 1 and make the preceding pin hole of needle tip by the situation of blood vessel wall shutoff, reverse pin hole 2 still can carry out the infusion of liquid, thus the venous transfusion when being more suitable for magnetic resonance examination.The venipuncture needle that is used for magnetic resonance described in the utility model, overall structure is simple, easy for operation, use immobilization with adhesive tape, reliable and stable, can prevent preferably needle point 1 on float vibration with syringe needle, and just in case float on taking place owing to needle point 1 make that the preceding pin hole of needle tip is by the situation of blood vessel wall shutoff under, oppositely pin hole 2 still can carry out the infusion of liquid, guarantees normally carrying out of magnetic resonance examination.
