What is a Luer lock Adaptor?

The Luer lock adapter includes a housing that defines an axis and an internal Luer lock element with a thread. The internal Luer lock element is located inside the housing and is rotatably mounted on the housing for rotating relative to the housing about the axis This allows the Luer lock element to rotate relative to the housing around the axis in a first rotation direction and restricts the Luer lock element to rotate relative to the housing around the axis in a second rotation direction opposite to the first rotation direction, thereby, The position of the internal Luer lock element within the housing prevents manual access to the internal Luer lock element to limit its rotation in the first rotational direction.

What is the difference between male and female Luer lock?

In the electronics and mechanical industries, whether for trade convenience or manufacturing, connectors or some fasteners are usually designed as male and female ends. Generally speaking, the role of the female terminal is to receive and accept the male terminal. There are one or more protrusions, or a section that can be inserted into other parts is called a male end, and vice versa, receiving, or a notch is called a female end. Luer lock (Luer taper) is a standardized micro non-permeable joint, which is connected by a male Luer slip adapter (internal screw connector) and a female Luer connector (external screw connector). To sum up, almost all syringes are male Luer which have a protruding drill bit, and almost all needles are female which possess a small hole for the male drill bit to plug.

What is Luer Lock Connector Used for?

Luer lock connector is a convenient connection device used in the medical industry, which greatly simplifies the management of liquid and gaseous medical fluids. The luer lock connector can switch 4 infusion bags without plugging and unplugging the patient's infusion needle. A double male Luer lock adapteris often used. This joint also allows multiple compatible fluids to be managed using the same tube, thereby reducing wounds on the patient. What’s more, the male Luer lock to barb connector is easy to install, provides extremely durable and long-lasting connections, and can be used for all brands of hoses.
