Extension tube is a medical device used to connect the infusion device to the patient's blood vessels. One end of it is connected to the infusion set, and the other end is connected to the patient's vein through puncture to form a closed infusion channel. This channel ensures that drugs and liquids can enter the patient's body smoothly and accurately, while avoiding the damage and inconvenience caused by frequent puncture of blood vessels.
Specific types of extension tubes include disposable venous extension tubes and micro pump extension tubes. Disposable venous extension tubes are mainly used for conventional infusion therapy, hemodialysis, blood transfusion, blood collection and other medical operations, which relieves the patient's pain and improves medical efficiency. The micro pump extension tube is used to connect the micro pump to the patient or the device to achieve liquid delivery and control.
The design of the extension tube usually includes an inner conical joint, an outer conical joint, a water stop clamp and a pipeline component, and the materials are mostly ABS resin and polyvinyl chloride. Its advantages include relieving patient pain, improving medical efficiency, monitoring vital signs, and being economical and environmentally friendly. During use, medical staff need to strictly abide by operating procedures and regularly check the position and patency of the extension tube to ensure the safety of the patient.
