摘要： A face shield and head covering combination is provided. The head covering comprises a body and an attachment element. The body defines a head opening configured to receive a user's head therethrough. The attachment element is coupled to the body and configured to couple to a face shield positionable on the user's face. The attachment element is configured to transition between a first position on the body and a second position on the body, wherein the second position is spaced from the first position.

摘要： Apparatus for removing undesirable resonance in a closed, tubular fluid flow system permitting more accurate transducer measurement of varying fluid pressure within the system is disclosed. The apparatus includes a compliant air cavity coupled to the system via a small diameter aperture, or passage. The cavity is within an elongated pipe, or tube, the proximal end of which is inserted in a conventional cylindrical sleeve and includes the small diameter passage for coupling the air cavity to the fluid system. A plurality of such elogated tubes, each having a predetermined length and thus a predetermined cavity size, are provided for selective insertion in the cylindrical sleeve for providing the fluid flow system with a fixed series hydraulic resistance and an incrementally variable parallel hydraulic capacitance for matching the hydraulic impedance of the system. The elongated tubes may be color-coded to facilitate proper tube selection for optimum impedance matching in providing for the selective suppression of undesirable system resonance and associated improved transducer frequency response. The apparatus of the present invention is particularly adapted for use in a catheter-tubing-transducer system as used in electromanometry systems and permits a varying hemodynamic pressure to be more accurately measured and recorded.
