Description

Disposable venous transfusion needle-free transfusion device

Technical Field

The application relates to the field of medical instruments, in particular to a disposable infusion apparatus without an intravenous infusion needle.

Background

Intravenous infusion therapy is the most common clinical treatment means, and has great influence on the treatment and outcome of diseases. The percentage of hospitalized patients receiving intravenous therapy is reported in the literature to be as high as 70% to 90% (sovereign et al, 2010). The disposable infusion apparatus is used for establishing a channel between veins and liquid medicine for intravenous infusion. The venipuncture tools used in the hospital at present comprise a disposable transfusion steel needle, a vein indwelling needle, a CVC, a PICC, a transfusion port and the like. According to the relevant requirements of the specification, the disposable intravenous infusion steel needle is suitable for short-term or single administration, and is preferred to be used for indwelling infusion for patients who need long infusion time, high drug concentration and need nutrition supplement and blood transfusion.

At present, the specification of the transfusion system on the market has ordinary transfusion system, the bag formula transfusion system, the light-resistant transfusion system, precision transfusion system etc, the transfusion system mainly uses with disposable venous transfusion needle is supporting, disposable venous transfusion connects (the device has contained the protective sheath, the protective cap, the needle tubing, the hose, products such as needle file), but in actual clinical work, the nurse is to having left the vein to keep somewhere the needle, CVC, PICC does not need to use the transfusion needle even the patient of infusion port, give the patient and connect the infusion operation after, the nurse all need to separate and reprocess the transfusion needle of taking the needle, cut the hose of venous puncture needle, lose the transfusion needle head into the edge tool box again. The method not only wastes resources, but also increases the task for clinical nursing work, and increases the hidden danger of needle stick injury due to the existence of the transfusion needle head. It is a redundant device for patients with indwelling infusions.

In the process of infusion, the inpatient often has the inspection and treatment that need carry out immediately, needs to suspend patient's infusion this moment, and the nurse after with the transfusion system with keep somewhere the passageway separation, can use the disposable puncture needle of independent packing or the protective cap of tee bend to be connected with the transfusion system and prevent the pollution, and this has undoubtedly also increased clinical consumptive material, has also increased the risk of infection.
