A multilayer evacuated blood collection tube is provided having a first tube layer, and a second tube layer formed on the first tube layer and a closure, the second tube layer being a nanocomposite barrier layer. Such containers include but are not limited to blood collection tubes, evacuated blood collection tubes, centrifuge tubes, culture bottles, and syringe barrels.

Multilayer containers

A co-injection process is provided for fabricating improved multi-layer containers, including but not limited to blood collection tubes, evacuated blood collection tubes, culture bottles, centrifuges tubes, and syringe barrels. The container includes a tube () having a bottom wall () and a side wall () with an open end (). The container can be provided with a stopper having an upper portion () and a skirt with an outside portion (), a well () and a cavity (). The tube and stopper assembly can be used for medical purposes including containing a blood sample within an enclosed interior space ().

Process for forming multilayer containers

A method for forming a disposable non-latex tourniquet from a thermoplastic elastomer and an additive comprising slip and anti-block components.

Method of making a disposable non-latex tourniquet

A disposable non-latex tourniquet formed from a thermoplastic elastomer and an additive comprising slip and anti-block components. More particularly, the disposable non-latex tourniquet is formed from a metallocene octene based polymer and an additive comprising slip and anti-block components. The disposable non-latex of the present invention substantially minimizes discomfort to the patient and facilitates ease of use in knotting and releasing the tourniquet from the patient.
