SENSOR PATCH, SYSTEM, AND METHOD FOR DETECTING FLUID LEAKAGE
A sensor patch, system, and method for detecting a fluid leaked from a target site of a subject are provided. The sensor patch (100) includes a first detecting unit (127), a second detecting unit (128), and a patch body (110). The first detecting unit (127) includes a first pair of sensors (120A) respectively having a first end (121A) configured to be placed approximating the target site, while the second detecting unit (128) includes a second pair of sensors (120B) respectively having a first end (121B) configured to be placed away from the target site. Each sensor includes a conductive wire (125) and an insulating sheath (126) encapsulating the conductive wire (125) in a manner that a portion of the first end (121A, 121B) of the conductive wire (125) is exposed yet without directly contacting the subject's skin. The patch body (110) has an adhesive surface (104) for securing the first and second detecting units (127, 128) to the subject. The sensor patch enhances the detection specificity.
Capacitance-Based Patient Line Blockage Detection
A dialysis machine (e.g., a peritoneal dialysis (PD) machine) can include a pressure sensor mounted at a proximal end of a patient line made of a distensible material that provides PD solution to a patient through a catheter. During treatment, an occlusion can occur at different locations in the patient line and/or the catheter. When an incremental volume of additional solution is provided to the patient line while the occlusion is present, a change in pressure results. The change in pressure depends on the dimensions and the distensibility of the non-occluded portion of the patient line. If the change in pressure, the incremental volume, the properties related to the distensibility of the patient line, and some of the dimensions of the patient line are known, the location of the occlusion can be inferred. The occlusion type can be inferred based on the determined location.
Advanced dialysis catheter with pressure sensor
The present disclosure relates to a hemodialysis catheter that can monitor intravascular pressure using a MEMS sensor. The hemodialysis catheter comprises a venous lumen, an atrial lumen, and at least one MEMS system sensor. The hemodialysis catheter also comprises a data acquisition and processing system. The hemodialysis catheter can communicate with a monitor system to display pressure data.
Medical wetness sensing devices and related systems and methods
A medical wetness sensing device includes a base adapted to be disposed on a wearer of the medical wetness sensing device. The base includes a first electrical conductor and a second electrical conductor electrically insulated from the first electrical conductor. The first electrical conductor includes a hinge portion enabling a first portion of the first electrical conductor to deflect, at the hinge portion, relative to a second portion of the first electrical conductor. The medical wetness sensing device includes a controller electrically connected to the first electrical conductor and the second electrical conductor. The controller is configured to detect a presence or an absence of a medical fluid electrically connecting the first and second electrical conductors.
System and method for opening a concentrate container and connecting the concentrate container to a blood treatment device
The present invention refers to a system and method for opening a concentrate container without the need for a human to directly handle the concentrate container and connecting the concentrate container to a blood treatment device. Aspects of the invention are directed to a container for concentrate and a blood treatment device.
Occlusion detection devices, systems, and methods
A monitoring device may include a housing, which may include a distal end, a proximal end, and a fluid pathway extending through the proximal end and distal end. The distal end may include a connector configured to couple to a catheter assembly. The monitoring device may include one or more sensors disposed within the fluid pathway. The sensors may facilitate identification of an occlusion within the catheter assembly.
Flow Balancing Devices, Methods, and Systems
The disclosed subject matter relates to extracorporeal blood processing or other processing of fluids. Volumetric fluid balance, a required element of many such processes, may be achieved with multiple pumps or other proportioning or balancing devices which are to some extent independent of each other. This need may arise in treatments that involve multiple fluids. Safe and secure mechanisms to ensure fluid balance in such systems are described.
Medical device dislodgment detection
In examples described herein, a system includes an elongate member configured to be introduced into vasculature of a patient. The elongate member includes a pressure sensor configured to generate a pressure signal indicative of pressure in the vasculature adjacent the needle. The system includes processing circuitry configured to receive the pressure signal from the pressure sensor, detect, based on the pressure signal, dislodgment of the elongate member from the vasculature, and generate an output in response to detecting the dislodgment of the elongate member from the vasculature.
Flow modulation devices and methods of use with a hemodyalisys fistula or a graft
A flow modulation device is positioned around a hemodialysis fistula or a graft and includes a non-expandable outer jacket with an inwardly-inflatable flow-modulation chamber positioned inside thereof. The flow modulation chamber is configured to be in fluid communication with a control chamber via a flexible catheter. The control chamber includes a puncture-resistant housing having an inner cavity covered by a self-sealing elastic membrane sealingly attached thereto and configured for repetitive needle punctures. Upon injection of fluid into the control chamber via a needle puncture, the flow modulation chamber inflates inwardly to compress the hemodialysis fistula or the graft causing a reduction of blood flow therethrough.
