3 results about "Catheterization procedure" patented technology

There is provided a computer implemented method, comprising: in a plurality of iterations over a plurality of time intervals, in real-time during a catheterization procedure: accessing a plurality of time-spaced sequential images depicting blood vessels of tissue in at least one contrast state, the plurality of time-spaced sequential images captured over a time interval of the plurality of time intervals and at one or more image planes, creating an aggregated image by stacking and / or concatenating the plurality of time-spaced sequential images, feeding an input image comprising the aggregated image into at least one ML model, and over successive time intervals, monitoring outcome of the at least one ML model for an adverse event that developed in real-time during the catheterization procedure, the outcome including a label indicating a location of at least one blood vessel in which the adverse event occurred.

This invention provides a dual-segment, dual-color pH comparison catheter for clinical identification of premature rupture of membranes, belonging to the field of medical catheter technology. It includes a main catheter tube with a urine segment pH membrane and an amniotic fluid segment pH membrane sequentially arranged along the axial direction on the anterior outer wall of the main tube. The urine segment pH membrane has a color development range of pH 5.5-6.5, and its color change is a continuous gradient from yellow to green. This invention achieves zero-sampling detection under sterile conditions, highly integrating pH identification function into routine catheterization procedures. The pH value of urine and any potentially mixed amniotic fluid is simultaneously detected upon catheter insertion into the bladder, without the need for vaginal speculum, sampling swabs, or any form of secondary sterile opening. This design completely blocks the path of exogenous bacteria into the maternal reproductive tract at a physical level, thereby fundamentally and effectively reducing the incidence of clinically common chorioamnionitis and urinary tract infections, and improving perinatal medical safety and quality.

A wireless intelligently controlled drug-releasing intravesical floating drug delivery device and system, the device includes a housing, a drive module, a control module, and a power supply module. The housing is configured to enter the bladder via the urethra and float within the intravesical urine, the housing is internally provided with at least one drug chamber for containing drug and a gas chamber for providing buoyancy. The drive module is disposed within the housing and configured to cause drug to be discharged from the drug chamber to the exterior of the housing in a timed and / or quantified manner. The control module is configured to control the operation of the drive module. The power supply module is disposed within the housing and configured to supply power to the drive module. The system reduces the need for repeated, long-term, and invasive catheterization procedures during bladder perfusion therapy.
