SYSTEMS, DEVICES, AND METHODS FOR EXTRACORPOREAL REMOVAL OF CARBON DIOXIDE
Systems, devices, and methods are provided for removing carbon dioxide from a target fluid, such as, for example, blood, to treat hypercarbic respiratory failure or another condition. A device is provided including first and second membrane components for removing dissolved gaseous carbon dioxide and bicarbonate from the fluid, which can be done simultaneously. The device can be in the form of a cartridge configured for use in a dialysis system. A method of treatment is also provided, involving drawing blood from a patient and bringing the patient's blood in contact with a first membrane component having a sweep gas passing therethrough, and a second membrane component having a dialysate passing therethrough. The dialysate's composition can be selected such that charge neutrality is maintained.
OXYGENATOR AND EXTRACORPOREAL MEMBRANE OXYGENATION DEVICE
Disclosed are an oxygenator and an extracorporeal membrane oxygenation device. The oxygenator includes a housing; an oxygenation chamber, arranged in the housing, and having a blood flow pipeline extend through a blood inlet and a blood outlet; a partition plate, arranged between the housing and the oxygenation chamber, the partition plate is arranged in a same direction as the upper end cover and divide the interior of the housing into a heat medium chamber and a gas chamber. The oxygenator combines the design of a heat medium chamber and a gas chamber to perform brand-new optimization design on a blood flow path, a gas pipeline and a heat medium pipeline of a membrane lung, so as to obtain the best hemodynamic performance, uniform distribution of internal flow fields and pressure fields, small flow retention zone, low blood flow resistance and high gas blood exchange efficiency and heat exchange efficiency.
Devices for endovascular access through extracorporeal life support circuits
Adaptors, cannulas, caps, tube couplers, and systems thereof provide endovascular access through an established ECLS system. Adaptors having curved or angled shafts navigate right angle side ports of standard bypass cannulas and permit hemostatic introduction and direction of an intervention device to the axial flow path of the cannula lumen and bypass system. A modified cannula having an angled side port is also provided for use as an arterial cannula. A cap having an occluding surface may be inserted into the angled side port to prevent blood from stagnating in the angled side port. A tube coupler is also provided having an access port, such as an angled access port, and may be spliced into an established bypass system for vascular access point. Multiple couplers can be used to provide multiple access points. The adaptors and occlusive cap are interchangeable with each other and with secondary circuits.
APPROACHES TO MITIGATING PRESSURE APPLIED TO IMMOBILIZED PATIENTS UNDERGOING TREATMENT BY UNDERLYING SURFACES AND ASSOCIATED SYSTEMS
Introduced here are pressure-mitigation apparatuses able to mitigate the pressure applied to a human body by the surface of an object. A controller device can be fluidically coupled to a pressure-mitigation device that includes a series of selectively inflatable chambers. When a pressure-mitigation device is placed between a human body and a surface, the controller device can continuously, intelligently, and autonomously circulate air through the chambers of the pressure-mitigation device. As further discussed below, the controller device may cause the chambers to be selectively inflated, deflated, or any combination thereof. Such an approach is useful in a variety of contexts. For example, pressure-mitigation apparatuses may be used to improve treatment of patients suffering from respiratory illnesses and patients who are partially or completely immobilized for extended durations (e.g., as part of a medical procedure).
