Abstract:
1. A vascular blood containment device for ascertaining whether a blood vessel has been accessed and permitting a user to determine whether the vessel accessed is a vein or artery, the blood containment device comprising: an outer housing, the outer housing having a clear portion permitting the user to view inside the outer housing; an inner member having at least a portion thereof positioned internal to the outer housing so as to form a blood containment chamber between the inner member and the outer housing, the clear portion surrounding the blood containment chamber so as to permit a user to observe a rate at which blood fills the blood containment chamber such that the user can determine whether an accessed blood vessel is a vein or artery based on the fill rate; the inner member comprising a first aperture disposed at a distal end of the blood containment chamber, and through which blood enters the blood containment chamber; the outer housing comprising a second aperture disposed at a proximal end of the blood containment chamber and through which air is vented as blood fills the blood containment chamber; and a compression seal positioned between the inner profile of the outer housing and outer profile of the inner member and adjacent to the venting aperture and such that the compression seal is disposed against both the inner profile of the outer housing and the outer profile of the inner member, the compression seal being constructed of material adapted to permit passage of gas through the compression seal and out the second aperture when dry but prevent passage of liquid through the compression seal when contacted by liquid.
