Abstract: A chain for a particulate material extrusion pump includes a plurality of links, each of the plurality of links having a link body and a link ledge, wherein each link ledge of the plurality of links at least partially overlaps the link body of an adjacent one of the plurality of links.

Abstract: An apparatus that promotes the flow of materials has a body having an inner shape for holding the materials, a wall having a shape that approximates a portion of the inner shape of the body, and a vibrator attached to the wall. The wall may be disposed vertically within the body close to the body's inner shape. The vibrator transfers vibrations to the wall to agitate the material and encourage material flow.

Abstract: A track assembly for a particulate material extrusion pump according to an exemplary aspect of the present disclosure includes a link assembly with a roller bearing. An insert mounted to a load beam located such that the roller bearing contacts the insert.

Abstract: A bowel control probe and method of detecting and preventing bowel incontinence. The probe has a body with a distal end which is permeable to gas. Conductivity sensors on the probe will establish an electrical circuit in the presence of fecal matter to send an alert signal to a control unit. The sensors may be partially shielded by a removable sleeve to reduce false alarms resulting from moisture. The control unit may issue an audible or visual alarm and may transmit a signal to a remote nursing station. An air cuff about the probe body is cyclically inflated and deflated to block passage of fecal matter and to protect tissue and capillaries in the rectal area.

Abstract: An intravenous administration set assembly (10) is disclosed which is capable of introducing fluid from a plurality of sources of intravenous fluids into a patient and which allows the various sources of fluid to be easily attached and detected from the assembly without the necessity for intravening safety steps, such as purging the system, and yet without any possibility of air or bacteria being introduced through the system into the patient. An air-eliminating filter (32) is attached to a manifold formed of fittings (26) which are connected through inlet adapters (28) to the sources of intravenous fluid. The air-eliminating filter (32) ensures that air or bacteria introduced into the assembly (10) through attaching or detaching sources to the assembly does not pass to the patient and also ensures that a head pressure is maintained relative to the venous pressure of the patient to prevent a back flow of blood from the patient into the assembly.
