BLOOD PUMP FOR CAUSING BLOOD TO FLOW IN ONE DIRECTION AND BLOOD OXIDATION SYSTEM COMPRISING SAME
20230233833 · 2023-07-27 ·

A blood pump for causing blood to flow in one direction is used for a blood oxidation system that circulates blood in a body to an oxidizer so as to supply oxygen into the body from outside the body. The blood pump includes an outer wall having a gas outlet port formed through a lateral surface thereof; a blood chamber having a pouch which is inserted into the outer wall and of which opposite ends are connected to opposite ends of the outer wall, respectively; a pump injection valve fluid-communicably coupled to one end of the blood chamber and blocking blood from flowing to the blood chamber; and a pump discharge valve fluid-communicably coupled to the other end of the blood chamber and blocking blood from flowing from the blood chamber.

REGULATING BLOOD FLOW IN EXTRACORPOREAL CIRCULATION

A system for regulating blood flow in extracorporeal circulation, and including a blood reservoir to receive blood from a patient, an oxygenator to condition the blood, a centrifugal pump to pump the blood from the blood reservoir to the oxygenator and back to the patient, an electronic remote clamp to regulate flow of the blood, and a controller to operate in a flow control mode and a speed control mode. The controller includes an operational element to set a blood flow value in the flow control mode and to set a speed of the centrifugal pump in the speed control mode. The controller to automatically switch between the flow control mode and the speed control mode in response to one or more trigger conditions and to automatically switch between the speed control mode and the flow control mode in response to opening the electronic remote clamp.

Dual lumen extracorporeal membrane oxygenation catheter with single entry port bypassing the right heart and lungs

The invention pertains to a medical device: an ECMO (extracorporeal membrane oxygenation) catheter which can be used during right heart and lung failure. It pertains to a dual lumen catheter with a single port of entry which when in place bypasses the right heart and lungs while completing the veno-arterial circuit.

11603878 · 2023-03-14 · ·

A mount interface is described that includes a latch; and a latching assembly configured to receive the latch so as to lock the latch at a set position with respect to the latching assembly, wherein the latching assembly includes a housing provided with an irregular orifice configured to receive the latch; a first plug disposed in the housing so that a first portion of the irregular orifice overlies the first plug; and a second plug disposed in the housing adjacent the first plug so that a second portion of the irregular orifice overlies the second plug. Such a mount interface provides rapid and secure locking of a latch to the latching assembly.

Endovascular Cannula for Defining a Border of a Transport Volume for an In-Vivo Fluid Transport, Cannula System and Corresponding Method
20220331504 · 2022-10-20 ·

Described is an endovascular cannula (L1b, L2b) for defining a border of a transport volume (TrV) for an in-vivo fluid transport, the cannula (L1b, L2b) comprising:—a lumen portion (LP) that extends between a proximal end of the cannula (L1b, L2b) and a distal end of the cannula (L1b, L2b), the lumen portion (LP) defining an inner lumen, and—an expandable arrangement that has a non-expanded state and an expanded state, wherein the expandable arrangement can be switched from the non-expanded state to the expanded state, wherein in the expanded state the expandable arrangement is adapted to define at least one border of the transport volume (TrV), and wherein the border is configured to separate the transport volume from a body fluid circuit (BC).

Extracorporeal circulation management device with heartbeat synchronizaton

An extracorporeal circulation management device pumps blood in synchronization with heartbeats of a patient based on measurements of blood flow. Maximum and minimum blood flow measurement samples are compared with upper and lower threshold values to identify candidate timing for a systolic phase and diastolic phase of the heartbeat. During pulsatile pumping of the blood using the candidate timing, differences in the pulsatile flow measurements are determined. Based on the size of the difference, a final correction may be made to identification of the systolic and diastolic phases, and the corrected phase information is used to start and stop the motor unit.

Ventilation System
20170368247 · 2017-12-28 ·

An oxygenation system for a ventilation system comprises an inlet for receiving oxygenation gas at an oxygenation gas flow rate into an oxygenator, and an exhaust gas remover to remove exhaust gas at an exhaust gas flow rate from the oxygenator, and one or more flow controllers for controlling the exhaust gas flow rate relative to the oxygenation gas flow rate. This allows the amount of total gas entering the oxygenator and the amount of total gas removed from the oxygenator to be controlled with greater accuracy.
