The present invention relates to a surgical drape for shoulder surgery. The surgical drape comprises a main covering layer having a front surface and a back surface, an absorbing layer applied to the front surface wherein a first cut is made through the absorbing layer and the main covering layer, the cut being configured that the drape can move over an arm through the cut, a limb sleeve having a closed end and an open end wherein the limb sleeve is assembled to the main covering layer at the open end and the cut aligned such that when the drape is moved over the arm through the cut, the arm is covered by the limb sleeve, and a tourniquet element having an elastic opening configured to move over an arm with a circumferential pressure on the arm, wherein perforations are provided in the limb sleeve for tearing off part of the limb sleeve and wherein the tourniquet element is assembled in the limb sleeve at a position between the open end of the limb sleeve and the perforations.

A sensor cartridge according to embodiments of the disclosure is capable of being used with a non-invasive physiological sensor. Certain embodiments of the sensor cartridge protect the sensor from damage, such as damage due to repeated use, reduce the need for sensor sanitization, or both. Further, embodiments of the sensor cartridge are positionable on the user before insertion in the sensor and allow for improved alignment of the treatment site with the sensor. In addition, the sensor cartridge of certain embodiments of the disclosure can be configured to allow a single sensor to comfortably accommodate treatment sites of various sizes such as for both adult and pediatric applications.

A sterile surgical drape includes left and right inflatable supports leveling the upper surface of the drape to better corral instruments during angiographic procedures. An optional center inflatable support helps center the drape and provides a continuation of this work surface. Multiple sealable openings can be provided at common groin and wrist locations.
