The apparatus and method for quickly measuring the hemoglobin content of a sample of blood uses a light reflectance measurement of the hemoglobin sample lysed in a membrane. The reflection is inversely proportional to hemoglobin concentration. A blood sample is loaded on to a nylon mesh and dispersed within a nylon membrane, both of which have been treated with a hemolyzing agent and surfactant, and air-dried. As soon as the blood sample contacts the reagent on the membrane, the red blood cells are lysed and the hemoglobin molecules are released and dispersed into the membrane by the action of surfactant. The hemoglobin apparatus emits light at 522 nm to the reflective surface of the membrane. The intensity of the reflected light is measured by a detector in less than 29 seconds. The intensity of the reflected light is converted to hemoglobin concentration, g/dL, or mmol/L by an interpolative comparison with stored reflection data indicative of known hemoglobin contents.

Hemoglobin test strip and analysis system

A portable device for performing coagulation tests on a patient's blood. Blood is first drawn from a patient using a lancet. The blood is then supplied to a disposable cuvette placed within the testing device. The blood is drawn into multiple conduits within the cuvette. Each of the conduits contains a dried or lyophilized activation reagent that is rehydrated by the blood. The blood in each of the conduits is then reciprocally moved across a restricted region until a predetermined degree of coagulation occurs. Since the coagulation time is being monitored in multiple conduits, a representation coagulation time for a given sample can be determined. In at least one of the conduits a normalizing control agent is present. The normalizing control agent counteracts any effects of anticoagulants present in the blood sample, thereby allowing the blood sample to have generally normal coagulation characteristics. The normalized blood is tested simultaneously with the untreated blood to provide a reference value against which the functionality of the test system and the quality of the sample can be judged.

Blood sampling device

A method for circumcising a penis having a foreskin encircling the glans penis using an apparatus having a cap, a guide clamp, and a blade holder mechanism. The cap defines an interior space and has an outer surface. The glans penis of the penis is placed in the interior space defined by the cap. The foreskin of the penis is positioned around an outer surface of the cap. The clamp is positioned over the foreskin such that a portion of the foreskin is interposed between the clamp and specific features on the outer surface of the cap. The guide clamp is secured in a position over the foreskin of the penis crushing the skin to prevent bleeding. The blade holder mechanism is placed on the guide clamp and rotated around the guide clamp so that a blade carried by the blade holder mechanism cuts the foreskin. The blade is mounted on a flexible finger within the blade holder and as such is exposed for cutting only during use. At all other times the blade is safely contained within the blade holder body.

Portable test apparatus and associated method of performing a blood

A blood sampling and transferring device including a disposable auto-pricking lancet and a reservoir integrated together for creating a skin incision and collecting a blood sample therefrom in a one-step operation. The reservoir is preferably funnel shaped with a large opening at one end for receiving the blood sample from the patient, and a small opening at the other end which is small enough to prevent unassisted passage of the collected blood therethrough. The blood sample can then be temporarily stored until such time as the sampling device is engaged with a blood testing device that has an aperture to accommodate the small opening of the reservoir and a pump to draw the blood from the reservoir for testing.
