An airway management system, comprising: a breathing circuit connector component, an inner tube component, and a connecting tube, further comprising: a laryngeal mask component and a telescopic tube component; or, an endotracheal tube component, the breathing circuit connector component comprises a breathing circuit connector; a plurality of cavities is provided in the laryngeal mask airway tube of the laryngeal mask component; a plurality of cavities is provided in a endotracheal tube of the endotracheal tube component; and one end of the breathing circuit connector is connected to a laryngeal mask connector of the laryngeal mask component, or an endotracheal tube connector of the endotracheal tube component, or the laryngeal mask connector and an inner tube connector of the inner tube component, or the endotracheal tube connector and the inner tube connector, or a telescopic tube machine end connector of the telescopic tube component and the inner tube connector.

A blood pump-oxygenator system comprises a blood pump, oxygenator, blood flow inlet, and blood flow outlet forming a circuit operable as a cardiopulmonary bypass system for extracorporeal processing of the patient's blood, wherein the first blood pump conveys blood through the circuit from the patient into the blood flow inlet, through the oxygenator and out of the blood flow outlet back into the patient. The system further comprises a recirculation loop between the blood flow inlet and blood flow outlet that accommodates the first blood pump and oxygenator, wherein the first blood pump circulates at least part of the blood in the circuit through the recirculation loop such that blood passes through the oxygenator multiple times and is repeatedly subject to exchange of O.sub.2 and CO.sub.2 within the oxygenator. A valve between the recirculation loop and blood flow outlet controls an amount of blood flowing through the recirculation loop.

A blood pump-oxygenator system for increasing perfusion and oxygen level in a patient comprises a blood flow inlet and outlet forming a circuit operable as a cardiopulmonary bypass system for extracorporeal processing of blood, a first blood pump and first oxygenator. The first blood pump conveys blood through the circuit from the patient into the blood flow inlet, through the first oxygenator and out of the blood flow outlet back into the patient. The system further comprises a second blood pump and second oxygenator. The second blood pump conveys blood through the circuit from the patient into the inlet, through the second oxygenator and out of the outlet back into the patient. A pump control unit controls the first and second pumps to increase or decrease blood flow rate through the respective oxygenator to vary a ratio of flow rates of blood through the first and second oxygenators.

The present disclosure generally relates to fluid control valves for delivering and/or aspirating fluid during surgical surgeries and procedures. In one embodiment, an apparatus comprises a valve body comprising a first conduit defining a first port, and a second conduit defining a second port and a third port. A cavity is defined in the valve body between the first conduit and the second conduit. The cavity is fluidly coupled with the first conduit via a first channel having a smaller diameter, and with the second conduit via at least one second channel. The apparatus further comprises a hydrophobic filter attached to the valve body and extending substantially across the cavity. The apparatus further comprises an activation member disposed in the cavity and defining one or more openings extending from a first side of the activation member contacting the hydrophobic filter, to an opposing second side facing the second conduit.

Catheter valve, including a valve housing defining a fluid channel, wherein the housing includes an asymmetric valve leaflet that is pivotal between a first position for allowing fluid flow through the fluid channel and a second position for closing the fluid channel, wherein the housing and valve leaflet are connected via a snap-fit connection. Further, there is provided a method for assembly of the catheter valve, including: providing the catheter housing; providing the valve leaflet; and snapping the valve leaflet into the housing.

A device for delivering an agent includes a valve assembly including an enclosure for storing the agent, an agitation mechanism rotatably disposed inside the enclosure, and a tube disposed inside the enclosure and extending through the agitation mechanism. The tube includes a channel having a longitudinal length defined between a first opening at a first end of the tube and a second opening at a second end of the tube. The agitation mechanism is configured to direct a fluid received in the enclosure towards the agent stored therein in response to rotating about the tube, thereby agitating the agent within the enclosure. The tube is configured to receive a mixture of the fluid and the agent at the second opening and direct the mixture through the channel for delivery out of the enclosure via the first opening.
