Abstract: A device to safely collect any fluid discharged through the biopsy cap into another container without contaminating the surrounding environment. A device that can be attached to an endoscope in order to collect any fluid discharged through an external opening of an endoscope's internal channel.

Abstract: A face mask that can be used for the ventilation of patients such as in bag-valve-mask resuscitator systems is provided. The face mask can be used to form a tight seal with the patient's mouth and nose, while also creating an open airway. The face mask includes a jaw (chin)-lifting member that can be used to position the patient's head in a tilted position. The invention also encompasses bag-valve mask resuscitator systems and methods for using bag-valve mask resuscitators in the ventilation of patients. In one embodiment, the bag-valve mask resuscitator is placed so that the bag is positioned over the midline of the face of the patient.

Abstract: A bearing cap (16) is sealingly inserted between a front bearing bush (3) and a fluid-tight sleeve (17). Between a front portion (10) of a rotor shaft (5) and the front bearing bush, two overlying lubricating grooves (11, 12) are disposed. On a rear portion (13) of the shaft, a baffle plate (20) having vanes is mounted, an annular gap (21) existing between the shaft and the inside diameter of the vanes. Between the rear portion of the shaft and a rear bearing bush (4), lubricating grooves (14, 15) are formed continuously. The rotor chamber is quickly vented, no contamination thereof taking place. Lubrication and heat evacuation from the rotor chamber are ensured.
