technical field

The invention relates to the technical field of intravenous syringes, in particular to an intravenous syringe for preventing bleeding for the nursing of idiopathic thrombocytopenic purpura.

Background technique

Idiopathic thrombocytopenic purpura is a clinical syndrome with increased platelet destruction due to abnormal immune function. Infusion operations are required when nursing patients. Most of the existing intravenous syringes are disposable infusion sets, and the infusion tubes contain The filter head and flow regulator are all made of PVC material, which cannot be recycled, resulting in waste of resources, complicated production steps, high production cost, low production efficiency, and insufficient energy saving and environmental protection;

In addition, the existing disposable infusion sets have few functions. Most of the needles are fixed on the patient's arm with tape. If the infusion tube is accidentally driven, the needle will easily shift and cause bleeding. In addition, during infusion in winter, the cold medicine reduces the comfort of the infusion. It is easy to cause discomfort to the patient, and the existing infusion requires the nurse or the patient to observe the infusion situation to prevent the infusion of the drug from being unable to be replaced in time.

In view of the above problems, the present invention proposes an intravenous syringe for preventing bleeding for idiopathic thrombocytopenic purpura nursing, which has the advantages of being able to be recycled, saving resources, reducing costs, improving production efficiency, and being convenient for fixation to prevent bleeding.
