摘要:
A method for performing an in-vivo calibration of a blood pressure sensor that is associated with an in-vivo balloon system. The method involves monitoring a patient's blood pressure by observing the system gas pressure while at the same time monitoring the patient's blood pressure through the sensor. The blood pressure measurements obtained by monitoring the system gas pressure are used as reference, or “true,” blood pressure measurements, and an “offset” is determined between the reference blood pressure measurements and the blood pressure measurements obtained through the sensor. The offset can be stored in a memory, which may also store sensor sensitivity data. The offset and/or sensitivity data may be used to adjust future measurements obtained from the sensor, thereby generating calibrated sensor measurements.

A dressing (100) for applying compression to a wound (14) in a patient includes a bladder (102) having a non-deformable end wall (104) and a deformable membrane (106). The dressing may include a flexible web (110) having an adhesive layer (120) on one side thereof for securing the dressing to the patient so as to hold the bladder against the patient's skin. Upon inflation, the deformable membrane projects towards the patient's skin and exerts pressure on the wound to reduce the flow of blood from the wound.
摘要:
A method for performing an in-vivo calibration of a blood pressure sensor 40 that is associated with an in-vivo balloon system. The method involves monitoring a patient's blood pressure by observing the system gas pressure while at the same time monitoring the patient's blood pressure through the sensor. The blood pressure measurements obtained by monitoring the system gas pressure are used as reference, or 'true, ' blood pressure measurements, and an 'offset' is determined between the reference blood pressure measurements and the blood pressure measurements obtained through the sensor. The offset can be stored in a memory 42, which may also store sensor sensitivity data. The offset and/or sensitivity data may be used to adjust future measurements obtained from the sensor, thereby generating calibrated sensor measurements.

Methods are provided for blocking non-specific and specific hybridization of nucleic acid samples on a microarray. The method of the present invention comprises applying a blocking reagent to the microarray, wherein the blocking reagent comprises modified nucleotide bases, preferably LNA (Locked Nucleic Acid -modified bicyclic monomeric units with a 2'-0- 4'-C methylene bridge). In further embodiments, the method includes applying a mixture including: a) a cDNA reagent obtained from mRNA of a target sample, the cDNA having a capture sequence; b) a dendrimer with a label for emitting a detectable signal and a second nucleotide sequence complementary to the capture sequence; and c) an blocking reagent containing LNA to a microarray, for producing a detectable signal from said label whereby a hybridization pattern is generated on the microarray.
摘要:
A mounting device (10) for securing transport patient connected equipment, specifically an intra-aortic balloon pump (IABP) (22), in the typically crowded medical transport vehicle. An engagement stud (20) on the IABP (22) slides into a spring-loaded latch (40) connected to a vehicle mounted base (11). The engagement stud configuration allows the user to engage the IABP (22) from any desired direction, i.e. slide the pump (22) from any of the four sides onto the mount (11). No effort is required from the user beyond the pushing motion for locking the IABP (22) onto the mount (11).
摘要:
A double lumen continuous flow dialysis needle (1) and cannula (20) having a contiguous lumens (2, 3) of different lengths, the shorter lumen acting as blood intake lumen and the longer as the blood return lumen, each lumen (2, 3) having a beveled edge (4, 5) sloping outwardly and away from the needle (1) which can be inserted percutaneously and which minimizes the possibility of mixing cleansed blood with blood entering the intake lumen.
