Definitions

  • the present invention relates to a protective device for reducing the risk to medical personnel of accidentally puncturing themselves on a hypodermic needle. It also relates to a method of reducing the risk to medical personnel of accidentally puncturing themselves on a hypodermic needle.
  • Testing including the use of a hypodermic needle is probably the most common clinical routine performed in modern medical care, e.g. to collect blood for tests, that are highly important diagnostic and prognostic tools in the everyday patient care.
  • Hemolysis is typically understood as the release of hemoglobin and other intracellular components from erythrocytes to the surrounding plasma, following damage or disruption of the cell membrane. Hemolysis may occur either in vivo or in vitro, and is a most undesirable condition that influences the accuracy and reliability of laboratory testing. Reasons to why hemolysis interferes with multiple biochemical analysis may be e.g. that hemoglobin interferes with the measurements (e.g. spectrophotometric methods), and also that the release of biochemical markers from the broken red blood cells causes false high values of these substances.
  • US 4,892, 107 discloses a single use safety blood collection device comprising a cylindrical outer sleeve and an inner needle carrier holding a double-pointed needle in fluid communication with a vacuum tube and slidable within the outer sleeve between two positions. In the first position, the needle projects from the outer sleeve and is exposed for drawing blood. In the second position, the needle is retracted within the outer sleeve. The needle carrier is releasably held in the first position so that it can be readily moved into the second position after use. After the needle has been retracted into the sleeve the carrier is locked in its second position to prevent health care workers from coming into accidental contact with the used needle.
  • a safety blood collection device is useful for blood sample collection purposes, but cannot be used for taking a small sample of a liquid, e.g. blood to be tested for hemolysis, from sealed test tube or other sealed container.
  • the main object of the present invention is to provide a protective device for reducing the risk to medical personnel of accidentally puncturing themselves on a hypodermic needle, e.g. when assessing hemolysis (or any other analysis) in immediate connection to collecting a blood sample, said assessment being possible to perform by a user, e.g. in a treatment room without the necessity of a laboratory, and the protective device must permit a user to take a small sample of a liquid, e.g. blood to be tested for hemolysis, from sealed test tube or other sealed container, e.g. which has been manufactured under reduced atmospheric pressure and has lost all or most of its vacuum when filled with liquid.

  • a protective device reduces the risk to medical personnel of accidentally puncturing themselves on a hypodermic needle, primarily but not solely when assessing hemolysis in immediate connection to collecting a blood sample, and the assessment is possible to perform by a user, e.g.
