A catheter (plastic tube) connects the port to a vein. Under the skin, the port has a septum (a silicone membrane) through which drugs can be injected and blood samples can be drawn many times, usually with less discomfort for the patient (and clinician) than a more typical "needle stick".
V-Set: Multiple line IV injection site whereby several lines can be used at the same time for administering drugs to the patient.. In intravenous therapy a Y-Set, T-Set and V-Sets are Y-, T- and V-shaped three-way connector sets made of connecting plastic tubes used for delivering intravenous drugs into the body from multiple fluid sources.
When the needle enters the vein, venous blood pressure generally forces a small amount of blood into the set's transparent tubing providing a visual sign, called the "flash" or "flashback", that lets the practitioner know that the needle is actually inside of a vein. The butterfly offers advantages over a simple straight needle. The butterfly's ...
The plunger can be linearly pulled and pushed along the inside of the tube, allowing the syringe to take in and expel liquid or gas through a discharge orifice at the front (open) end of the tube. The open end of the syringe may be fitted with a hypodermic needle , a nozzle or tubing to direct the flow into and out of the barrel.
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein.The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth.
The purpose of an infusion set is to deliver insulin under the skin, fulfilling a similar function like an intravenous line. [1] It is a complete tubing system to connect an insulin pump to the pump user and as such includes a subcutaneous cannula, adhesive mount, quick-disconnect, and a pump cartridge connector.

A vacutainer blood collection tube is a sterile glass or plastic test tube with a colored rubber stopper creating a vacuum seal inside of the tube, facilitating the drawing of a predetermined volume of liquid. Vacutainer tubes may contain additives designed to stabilize and preserve the specimen prior to analytical testing.
Hypodermic needles are normally made from a stainless-steel or Niobium tube [17] through a process known as tube drawing where the tube is drawn through progressively smaller dies to make the needle. The end of the needle is bevelled to create a sharp pointed tip, letting the needle easily penetrate the skin. [18]
