摘要： A protective guard for a medical tubing connector includes a ring, at least one flexible member attached at a first end to the ring and having a second end, and a base attached to the second end of the at least one flexible member. The ring is configured to fit over a first connection member of the medical tubing connector, while the base is configured to fit over a second connection member of the medical tubing connector. When coupled with the medical tubing connector, the protective guard helps prevent a user from touching the medical tubing connector.

摘要： The invention includes devices and methods for obtaining samples of blood or other bodily fluids with reduced levels of contamination. Fluid obtained from a subject may be contaminated by skin cells, bacteria, fungi, viruses, phages, their respective RNA, DNA, and/or other undesirable molecules, or disinfectants. A first amount of fluid is injected from the subject through an distal needle and a proximal needle penetrates a first portion of a device having a sequestration chamber with sub-atmospheric pressure therein. A first portion of the fluid, containing contaminants, is deposited into the sequestration chamber. The proximal needle is then moved through a second portion of the sequestration chamber and into a collection container. Because contaminants are removed from the sample, analysis and diagnosis of a subject's condition becomes more reliable and accurate. Additional devices and methods can be used to obtain relatively uncontaminated samples from cell culturing vessels.
