摘要： The invention discloses a system, method and medical device for measuring various hemoglobin derivatives, such as oxyhemoglobin, reduced hemoglobin, partial hemoglobin, carboxyhemoglobin, methemoglobin and sulfhemoglobin in whole or in hemolyzed blood. The novel method uses a statistical approach to enable the design of a portable co-oximeter. This portable co-oximeter utilizes compact light sources, such as light emitting diodes or light emitting lasers, to emit light in the visible region. Being portable, the device is a point-of-care device that can be used in emergency situations by paramedics, in the emergency room, and in a physicians office to detect and measure the concentrations and/or percentages of functional and non-functional hemoglobin derivatives in a patient's blood.

摘要： An electronic sensor is described that includes a sample receptacle and a data storage device. The data storage device is powered by a pair of half cells on the sensor. The half cells contain ion solutions that are also used to calibrate the sensor. As the sensor is placed within a sensor data reader, the data stored on the data storage device is transferred to the reader along with measurements of the voltage potential between the half cells. The reader thereafter calculates a calibration slope curve for the sensor. The calibration slope curve is then used to determine the exact ion concentration of any sample that is placed in the sample receptacle.

摘要： Precalibrated, disposable electrochemical sensing devices can be constructed so as to utilize a housing shaped so as to internally include at least two separate half cells, one of which is capable of serving as a reference half cell and the other of which is capable of serving as a sensing half cell. The housing is shaped so as to include a top depression capable of being used as a container which is in communication with the interiors of the half cells. The depression is capable of holding for a sample to be analyzed using the device. The housing is preferably mounted on a board which is capable of being plugged into a female socket. This board carries electrodes which are connected to electrodes in the half cells.
