Example Embodiment

[0017] The drawings show specific embodiments of the invention.

[0018] Such as figure 1 The butterfly-wing blood sampling needle of the present invention shown includes a catheter 1. One end of the catheter 1 is fixedly connected with a venous blood sampling needle 2. The lower end of the venous blood sampling needle 2 is provided with a needle handle 3, and the other end of the catheter 1 is connected to a tube plug puncture needle through a needle seat 4 5Fixed connection, the needle seat 4 is provided with a sealing rubber ring 6 which is a truncated cone-shaped structure with anti-skid patterns on the surface, which greatly increases the stability and sealing of the tube plug puncture needle 5 inserted into the infusion bottle Sex, reducing the potential safety hazards of patients.

[0019] Wherein, the venous blood collection needle 2 is provided with a matching venous blood collection needle sheath 7, and the tube plug puncture needle 5 is provided with a tube plug punctur...

Abstract

The invention belongs to the technical field of medical supplies, and particularly relates to a butterfly type blood taking needle. The butterfly type blood taking needle is characterized by comprising a conduit, one end of the conduit is fixedly connected to a venous blood taking needle, the lower end of the venous blood taking needle is provided with a needle handle, the other end of the conduit is fixedly connected to a pipe plug puncture needle through a needle seat, the needle seat is provided with a sealing rubber ring, and the sealing rubber ring is of a truncated cone-shaped structure of which the surface is provided with skid resistance stripes. The butterfly type blood taking needle is simple in structure and convenient to use; the stability and air-tightness of the pipe plug puncture needle when being inserted into an infusion bottle are sharply improved, and the safety hazard of a patient is lowered; the cost is low, and thus the butterfly type blood taking needle can be conveniently applied and popularized.

Description

[0001] (1) Technical field [0002] The invention relates to a butterfly-wing type blood collection needle, which belongs to the technical field of medical supplies. [0003] (2) Background technology [0004] The existing blood collection needle has simple structure and single function, and in the process of use, the seal is not good and the connection with the drop bottle is not firm, which brings potential safety hazards to patients and is no longer suitable for use. [0005] (3) Contents of the invention [0006] In order to make up for the defects of the prior art, the present invention provides a butterfly-wing blood collection needle with simple structure, convenient use, good sealing effect, cleanness and durability. [0007] The present invention is achieved through the following technical solutions: [0008] A butterfly-wing blood collection needle, characterized in that: it comprises a catheter, one end of the catheter is fixedly connected to the venous blood colle...
