Abstract:
A tube for use in the automatic collection of a digital blood sample has its mouth fitted with a resilient detachable funnel member which can carry a capillary cannula and in which is held an absorbent annular plug through which pass and project two incisor lancets.
Abstract:
The present invention is concerned with a spectrophotometer useful for determining light transmission of microsamples. It is particularly concerned with a spectrophotometer system using an improved microcuvette and extremely small optical elements for providing and acting upon the light beam that is used in determining the light-transmission characteristics of the sample. It is more particularly concerned with a double-cavity cuvette for receiving in one of the cavities of the cuvette a comparison or reference material and, in the other, the sample to be measured. Even more particularly it is concerned with a doublecavity micro-cuvette particularly adapted for utilizing a shifted-beam light system in which the beam is alternately refracted in different directions to direct it alternately through one cavity and then the other.
Abstract:
Apparatus for automatically obtaining a percutaneous and digital blood sample in conjunction with a blood collector device having a resiliently crushable mouthpiece housing a pair of incisor lancets, the apparatus including a mounting for the collector device, clamping means for holding the tip of a finger on the crushable mouthpiece, a mechanism for striking the collector device in the mounting to drive the lancets into the finger, and means for massaging the finger to cause blood to flow out of the resulting incisions.
