Abstract: The present invention is directed to improved methods and apparatus for the collection of blood, which are particularly useful for autotransfusion purposes. The apparatus includes a conventional blood transfer bag which is in turn placed in fluid communication with an air-blood separator to form a collection system. This system is particularly adaptable for use in the surgical setting in that it can operate at high vacuum while minimizing hemolysis. This is accomplished by early separation of air from the blood as the blood is collected.The air-blood separator and the interior of the blood bag are placed in communication with a vacuum source. As a result, there is a pressure equalizing feature inherent within the device. This allows the blood to continue to flow through the device into the blood bag without extending or opening the blood bag. As a result, there is minimal air-blood interface as the blood enters the blood bag.

Abstract: The present invention is directed to improved methods and apparatus for the collection of blood, which are particularly useful for autotransfusion purposes. The apparatus includes an upper reservoir wherein the collected blood enters the device. A lower container is placed in fluid communication with the upper reservoir. Disposed within the interior of the container is a conventional blood bag which is in turn placed in fluid communication with the upper reservoir. The upper reservoir has two external connections. The first connection is for receiving blood from the patient. The second external connection places the upper reservoir in communication with a source of vacuum. In one embodiment of the present invention a filtering structure is disposed within the upper reservoir and is connected directly to the inlet connection from the patient. The filtering mechanism provides for early debubbling of the blood flowing into the device and also filters out any emboli or cell masses which may have developed in the collection process. In one embodiment of the invention, the apparatus described above is combined with an air-blood separator to form a collection system. This system is particularly adaptable for use in the surgical setting in that it can operate at high vacuum while minimizing hemolysis. This is accomplished by early separation of air from the blood as the blood is collected.The lower container and the interior of the blood bag are placed in communication with the vacuum source of the reservoir. As a result, there is a pressure equalizing feature inherent within the device. This allows the blood to continue to flow through the device into the blood bag without extending or opening the blood bag. As a result, there is minimal air-blood interface as the blood enters the blood bag.

Abstract: A noninvasive system and method for monitoring arterial oxygen saturation levels which may also be used to continuously and noninvasively monitor blood pressure, including generating a continuous blood pressure waveform. The apparatus of the described embodiment includes a red LED and an infrared LED which are positioned to direct their respective light beams into, or reflected by a patient's body part. A phototransducer device is positioned to receive the light beams which are transmitted through the body part. A pressure cuff surrounds the body part and the LEDs. During calibration periods, pressure is applied to the body part and the systolic and mean blood pressures are determined and the arterial oxygen saturation level in the body part is determined. The pressure is then released from the body part and another arterial oxygen saturation level is determined and the difference between the two oxygen saturation levels is used as a calibration factor during later monitoring periods to remove the effect of nonarterial oxygen saturation levels on the values obtained during the subsequent monitoring period. The systolic and mean arterial pressures measured during a calibration period are used to develop a Hardy model compliance curve wherein the pressure-volume relationship of the arteries is determined. The modulation of the red LED light beam which strikes the photodetector, which corresponds to changes in arterial volume, can be used according to the Hardy model to continuously calculate a blood pressure waveform for the patient.

Abstract: Method and system for sampling and determining chemical substances such as blood gases, in a fluid matrix, such as blood, by bringing the chemical substances into equilibrium with a liquid in a fiber probe, passing the equilibrated liquid to a sensor adjacent the equilibrium region and on into a hollow fiber line enclosed in a calibration chamber. Calibration of the sensors is accomplished by reversing the flow of liquid from the hollow fiber line to the sensors. In the system chemical substances for sensor calibration are provided by an electric proportioner whose output is continuously controlled by the output of the sensors such that the substances proportioned into a fluid in the calibration chamber surrounding the hollow fiber line are substantially the same as the substances within the matrix. The concentration of substances is determined by the output of the sensors and the amount of substances fed from the proportioner to the fluid surrounding the hollow fiber line. When the substances being measured are in equilibrium with both the matrix and fluid surrounding the hollow fiber line, a null response is obtained at the sensors.

Abstract: This invention teaches an improved high capacity frictional shock-absorbing assembly. The assembly comprises a housing with a first threaded member which is fitted therein for axial movement. A second threaded member is rotatably-fitted in the housing, but is restricted against axial movement. The first and second members are designed with compatible threaded surfaces for frictional engagement therebetween. A compression member is provided within the housing. The compression member is in engagement with the first threaded member to resist the axial movement of the first threaded member as it moves in a direction that will compress the such compression member.
