A method and non-transitory computer-readable medium for automating eFAST analysis of ultrasound scans. The method includes receiving at least one ultrasound image from one or more scan sites; processing the ultrasound image to determine whether there is a presence of one or more fluid pockets or free fluid present in the patient, the injury is selected from pneumothorax, hemothorax, and abdominal hemorrhage; and outputting a result from the processing. A model is trained on historical ultrasound images over a historical observation period, the historical ultrasound images associated with at least one injury determined directly observed presence of a fluid pocket or free fluid present in those images.

The present disclosure provides techniques for free fluid estimation including identifying a region of free fluid in an diagnostic image, calculating a free fluid measure based on the region of free fluid identified in the diagnostic image, and generating a volume class for the region of free fluid in the diagnostic image, wherein the volume class is generated by comparison of the free fluid measure to a data set of previously stored free fluid measures. The present disclosure may be implemented as a method, in a device, a computer readable medium, and a system, among other form factors.

Provided is a proportioner having one or more proportioner inlets to receive a common concentrated proppant fluid comprising a proppant, two or more flow lines fluidly connected to the one or more proportioner inlets, two or more proportioner outlets, each of the two or more proportioner outlets associated with one of the two or more flow lines, one or more fluid inlets, each of the one or more fluid inlets for introducing a proppant-free fluid to the proportioner, and a metering system associated with at least one of the two or more flow lines. Each metering system is positioned upstream of the proportioner outlet of the flow line with which it is associated and is fluidly connected with at least one of the one or more fluid inlets for proportioning one of the proppant-free fluids into the associated flow line at an injection point.

A computer implementation method for determining a specific temperature Tlog corresponding to a fixed viscosity point of a fluid. The method takes one value of fluid viscosity and one value of temperature as input. The method provides a characteristic temperature Tlog3 as output. The characteristic temperature Tlog3 is calculated using a VFT-like model, the variable parameters of the VFT-like model include a chemical composition-dependent variable parameter T0 that depends on the chemical composition of the fluid, and the variable parameters of the VFT-like model are statistically adjusted based on a dataset of temperature-viscosity values ​​obtained experimentally and / or simulated for the fluid within a chemical composition range.

This invention discloses a low-infection-risk detachable fixation wing and grooveless stop clamp hemodialysis catheter system, belonging to the field of medical device technology. This invention addresses two core pain points of existing long-term hemodialysis catheters: first, it redesigns the traditional one-piece fixation wing as a detachable structure, allowing for quick assembly and disassembly by external force without damaging the catheter, facilitating skin cleaning and reducing the risk of local infection and mechanical damage; second, it optimizes the separate stop clamp into a grooveless structure integrated with the connector, employing a full, smooth inner lumen to completely eliminate dead zones for bacterial residue, reducing catheter-related bloodstream infections at the source. This invention has a simple structure, strong clinical adaptability, and can be widely applied in the field of long-term hemodialysis treatment, demonstrating significant clinical application value.

A glue-free chemical solvent-free gas sampling tube and respiratory therapy equipment. The gas sampling tube includes: a gas delivery tube; a gas sampling tube connector, where the gas delivery tube is arranged on the gas sampling tube connector; and a locking fastener, where the locking fastener is configured to fix the gas delivery tube to the gas sampling tube connector. The gas sampling tube replaces in a solution of connecting the gas sampling tube connector and the gas delivery tube through glue or a chemical solvent in a conventional art by achieving a stable connection between the gas sampling tube connector and the gas delivery tube through the additionally arranged locking fastener, and then a novel glue-free chemical solvent-free gas sampling tube is provided, so that release of volatile organic matters is avoided fundamentally.

A method (100) for free fluid assessment of a patient, comprising: receiving (120) ultrasound imaging data of the patient's body; analyzing (130) the ultrasound imaging data to identify candidate free fluid in the patient's body, and to further detect one or more of the patient's organs in the patient's body; characterizing (140) the candidate free fluid by comparing the location of the candidate free fluid with the location of the one or more of the patient's organs, wherein the system characterizes candidate free fluid as confirmed free fluid when the location of the candidate free fluid does not overlap with the location of the one or more of the patient's organs, and wherein the system characterizes candidate free fluid as rejected free fluid when the location of the candidate free fluid overlaps with the location of the one or more of the patient's organs; displaying (150) a location of confirmed free fluid.
