A mask is disclosed that has a gas outlet which is quiet and provides for a diffused outlet flow of gases. The outlet is preferably a slot formed between a hollow body and cover over said hollow body. The mask also preferably extends and seals under a user's chin in use.

A device for removing obstructive material from a patient may include an elongate rotational member having a distal end and a proximal end, an internal irrigation catheter at least partially surrounding the rotational member, and an aspiration catheter at least partially surrounding the rotational member and the irrigation catheter. The distal portion of the rotational member is configured to change compliance of the obstructive material and facilitate obstructive material aspiration outside the patient.

A device removing a biological and/or chemical entity (C) from extracorporeal blood (B) is disclosed. The device has a hollow capture chamber with an inlet for the entry of the extracorporeal blood (B) and an outlet for the outflow of the extracorporeal blood (B) and a capture element inside the capture chamber having a reactant surface placed in contact with the extracorporeal blood (B) and a plurality of binding agents (A) for the biological and/or chemical entity to be removed (C) such that the biological and/or chemical entity (C), upon exiting the capture chamber, is removed from the extracorporeal blood (B) as linked to the reactant surface.

Systems and methods are provided for treating or preventing carbon monoxide poisoning. In particular, systems and methods are provided for a phototherapy treatment or prevention system that delivers light radiation to a patient's body to photodissociate carbon monoxide from hemoglobin.

The present utility model relates to a connector, a seal used therefor, and an anesthesia machine using the connector. The connector comprises first and second connection ports detachably communicating with an input port and an output port of an absorber canister respectively, and a seal. The seal comprises an annular ring and at least one lip. The annular ring is positioned on an inner sidewall of at least one connection port of the first and second connection ports. The at least one lip is annular and extends from an inner side of the annular ring in a direction away from the annular ring. When the absorber canister is in communication with the connector, a lower surface of the at least one lip of the seal contacts an outer sidewall of at least one port of the input port and the output port to form an annular contact surface, the width of the annular contact surface being greater than the thickness of a root portion of the at least one lip. The above technical solution reduces the resistance incurred when the absorber canister is inserted into the seal. The technical solution also enables the seal to have a longer service life and a good dynamic sealing performance.

A material chosen from alumina ceramic grafted with at least one aptamer, at least one antibody or their combination for capturing circulating foreign cells, preferably circulating tumor cells, the method of preparing such material, its use and the device comprising it are disclosed.

A system for performing an endoscopic surgical procedure in a surgical cavity of a patient that includes a multi-lumen tube set including a dual lumen portion having a pressurized gas line and a return gas line for facilitating gas recirculation relative to the surgical cavity of the patient, and a single lumen portion having a gas supply and sensing line for delivering insufflation gas to the surgical cavity of the patient and for periodically sensing pressure within the surgical cavity of the patient, a first gas sealed single lumen access port communicating with the dual lumen portion of the tube set and a second valve sealed single lumen access port communicating with the single lumen portion of the tube set.

The present invention relates to an insufflator with integrated flue gas extraction. Thanks to a novel valve regulation system, it is possible to direct the gas inflow through two tubes into the body cavity. The novel device also enables an improved pressure control of the body cavity, which leads to lower pressure variations in the body cavity and furthermore compensates higher leakage volume flows.
