Description
Technical Field
The utility model relates to the field of medical appliances, in particular to a disposable wedge-shaped needle handle vein puncture needle.
Background
The disposable vein puncture needle is widely applied to clinic and is used for performing vein puncture on patients needing vein medication or vein blood sampling, but the flat needle handle has certain defects when nurses perform vein puncture and hold the needle:
1. the angle of the original flat needle handle is increased when the original flat needle handle is held up and down in a pinching mode, the angle is easy to be large, blood vessels are easy to puncture, and therefore puncture failure is caused.
2. The contact surface between the front and back fingers is too small to facilitate the application of force, which may cause unstable needle holding or scratch the skin of the patient.
3. The thickness of the needle handle is increased properly, which is beneficial for the nurse to hold the needle handle, and is more stable than the traditional needle handle.
SUMMERY OF THE UTILITY MODEL
The utility model discloses through clinical observation and practice, to the fixed needs of patient's venipuncture, carry out technical improvement to disposable venipuncture needle, designed disposable wedge needle handle venipuncture needle, can avoid foretell all sorts of defects, the nurse that the needle held the custom around when overcoming current venipuncture is to the problem of holding the needle contact surface undersize, under the prerequisite of the nurse operation of not influencing the needle holding custom from top to bottom, provide a simple structure, safe in utilization and can conveniently hold the disposable wedge needle handle venipuncture needle of needle.
The purpose of the utility model is realized with the following mode:
disposable wedge needle handle vein pjncture needle, including infusion seat, infusion hose and the transfusion needle that connects gradually, infusion seat inside cavity, infusion needle is connected to infusion seat one end, and the transfusion needle is connected to the infusion seat other end, is equipped with wedge needle handle in infusion seat one side, wedge needle handle upper surface is the arc form, wedge needle handle bottom is the plane, and wedge needle handle vertical cross-section is fan-shaped, and wedge needle handle cross-section is trapezoidal, is equipped with the bump in wedge needle handle both sides.
The thickness of the wedge-shaped needle handle is not more than 6 mm.
The wedge-shaped needle handle is hollow.
The side surface of the wedge-shaped needle handle is concave, and the cross section of the wedge-shaped needle handle is splayed.
Compared with the prior art, the beneficial effects of the utility model are that: 1. the areas of the front side and the rear side of the front needle holder and the rear needle holder are increased, and the stability of holding the needles is improved.
2. The utility model discloses a bump of side increases the frictional force of finger and needle handle contact surface, is difficult for sliding when holding the needle, the operation of being convenient for.
4. The utility model discloses but ethylene oxide sterilization accords with aseptic technique requirement, reduces patient's infection rate.
5. The utility model can be independently packed or designed on a disposable venous transfusion device, and is convenient to use.
6. The utility model has the advantages of practical and simple design, low price, convenient operation and easy acceptance by clinical nurses.
