In the existing indwelling needle, generally include: puncture needle, indwelling needle tube and infusion catheter. When in use, the puncture needle is communicated with the indwelling needle tube and is inserted into the injection position of a patient, then the indwelling needle tube is guided into the blood vessel of the patient through the puncture needle, and finally the puncture needle is withdrawn, so that the indwelling needle tube is left in the blood vessel of the patient and is fixed by the application film. When in use, the liquid medicine is injected into the blood vessel of a patient through the infusion catheter.
However, the existing indwelling needle tube remains in the blood vessel of the patient, and blood embolism due to blood permeation in the needle tube is very likely to occur during the period of stopping infusion, and once the blood embolism occurs, the indwelling needle tube needs to be replaced again. In order to prevent the phenomenon of blood embolism in the indwelling tube, diluted heparin solution or normal saline is often injected into the indwelling needle tube through the three-way tube for tube sealing, the operation is complicated, the effect of preventing thrombus is also limited in time, and the tube sealing is usually required to be carried out again every 6-8 hours. In addition, when the transfusion is carried out again, the syringe is adopted to draw back blood, so as to judge whether the pipeline is unobstructed. These not only increase the operation of the nurse, but also increase the pain of the patient.
