Universal protection valve of transfusion utensil

Abstract

The invention relates to the technical field of an infusion apparatus, in particular to a safety valve used on an infusion apparatus. The infusion apparatus comprises an ebonite accessory and a soft gum base; wherein, the soft gum base is connected with the bottom of the ebonite accessory. The ebonite accessory comprises an ebonite accessory body and an ebonite accessory connection piece arranged at the lower end of the ebonite accessory body; the soft gum base is provided with a soft gum base connection piece which is matched and connected with the ebonite accessory connection piece. The safety valve with a simple structure is arranged in the infusion apparatus; through air pressure and liquid attraction, the safety valve can effectively close the infusion apparatus after the infusion, thus effectively preventing blood reflowing during infusion, which leads to air embolism and thrombus. In this way, medical negligence can be reduced to the large extent, simultaneously medical contamination and cross infection can be effectively avoided and medical disputes between medical staff and patients are reduced.

Description

Technical field: [0001] The invention relates to the technical field of infusion sets, in particular to a general safety valve for infusion sets. Background technique: [0002] An infusion set is a medical device often used in the treatment of diseases. At present, the commonly used infusion sets mainly include needles, air inlet pipes, upper infusion tubes, drip buckets, lower infusion tubes, adjustment switches and injection needles. When using an infusion set with this structure to infuse a patient, medical staff need to check the infusion situation frequently, especially when infusion for some elderly or children. When there is not much liquid left, the medical staff usually cannot leave. After the infusion is completed, the infusion needle must be pulled out immediately, otherwise the patient's blood will flow back to the infusion tube; during intravenous infusion, gas will enter the vein due to the effect of negative pressure, causing air embolism in the human body; ...

AI Technical Summary

Problems solved by technology

When using the infusion device of this structure to infuse the patient, medical staff needs to check the infusion situation frequently, especially when infusion is given to some old people or children. After infusion to the patient, the infusion needle must be pulled out immediately, otherwise the patient's blood will flow back to the infusion tube; during intravenous infusion, gas will enter the vein due to negative pressure, causing air embolism in the human body; Whether it is the thrombus formed by the backflow of blood or the air entering the blood vessels of the human body, it may cause death in serious cases, and it will also bring many doctor-patient disputes

In addition, the occurrence of blood backflow will also have a certain impact on the environment, because the blood flowing back on the infusion tube will remain on it, so if the used infusion set is not properly disposed of, it is likely to spread some This will not only bring certain harm to the patient itself, but also bring certain harm to the health of others.
