An embodiment includes a cardioplegia delivery system having a console, controller, and disposables. The console, in conjunction with the disposables, combines blood from the heart-lung machine and crystalloid from the IV-bag in a specified ratio and then adds in a drug (arrest agent and/or additive). The electro-mechanical console incorporates a blood/crystalloid pump, temperature controllable water circulation system, pressure and temperature monitors, a sensor interface with the disposables, an arrest agent pump, an additive pump and ultra-sonic air detection sensors. The system monitors and controls the blood-crystalloid ratio, drug concentration, flow rate, pressure, temperature, and delivery route of the cardioplegia solution delivered to the patient. The system is a software-controlled system with a graphical user interface controller. The controller is utilized to initiate/stop cardioplegia delivery, monitor delivery parameters and view/save relevant case information and data.

Myocardial protection system

An embodiment provides an adjustable band with non-occlusive retention in case of excessive force (i.e., automatically loosens) and traction for the broad use of tubing management in medical device and patient contact applications. Embodiments may further include features such as guides and or channels on the band to hold tubing. Embodiments may be secured to patients to be used as a non-adhesive securement aid for tubing/catheter (e.g., IV's, enteral tubes, Foley catheters, endotracheal tubes, nasogastric (NG) tubes, chest tubes, and the like) retention on patients.

Tubing management band

An embodiment includes a valve comprising: a valve channel that couples a valve input to a valve output; a one-way valve included within the channel; a filter; a first pressure relief port, wherein the first pressure relief port is configured to relieve negative pressure when pressure at the valve output is less than pressure at the valve input; a second pressure relief port, wherein the second pressure relief port is configured to relieve positive pressure when pressure at the valve output is greater than pressure at the valve input; wherein the one-way valve includes a monolithic portion that simultaneously seals the channel, the first pressure relief port, and the second pressure relief port; wherein the filter covers the first pressure relief port.
