KDS35 Small Animal Ventilator General Safety Summary Please read the following safety precautions to ensure proper use of your syringe pump. To avoid potential hazards and product damage, use this product only as instructed in this manual. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
KDS35 Small Animal Ventilator Description & Features The KDS35 is a volume controlled small animal/rodent respirator: •Strong motor and motor speed control with LED (light emitting diode) read-out of rate (stroke rate or breaths/min). •Vertical slide valve that has no “O”-Rings or passive check valves and requires no adjustments.
KDS35 Small Animal Ventilator Voltage Selection 1) 2) The ‘KDS35’ Ventilator is equipped with a 115/230V selector feature, which is incorporated into the power entry module located on the side of the unit (see figure below). The Ventilator is shipped from the factory with the voltage selector set at 115V. To change voltage from 115V to 230V, follow these steps: a) Turn off main power, and disconnect power cord.
KDS35 Small Animal Ventilator Pump Operation: CONNECTION TO THE ANIMAL The vertical slide valve has four ports (see figure below): •The top port (furthest from the chassis in new orientation) is the return channel from the animal, which leaves the Pump at the port on the side. It is at this top port that expired air can be collected or recycled. •The middle port is the room air/gas channel to the animal. •The bottom port (closest to the chassis in new orientation) is the room air or gas mixture intake.
KDS35 Small Animal Ventilator Pump Operation: (continued) SELECTION OF RATE AND VOLUME Refer to the Ventilator Graph (below) to select the appropriate tidal volume and respiration rate as a function of animal body weight. As a rough guide an adult rat will weigh between 200 and 500 grams with tidal volumes between 0.6 to 1.25 cm3 with respiration rates between 66 to 210 breaths/min. The average rate is 100 breaths/min. For most rodents the 5 cc cylinder will be adequate.
KDS35 Small Animal Ventilator Pump Operation: (continued) SETTING VOLUME The volume delivered is read by observing the excursion of the O-ring, on the piston, which is closest to the valve block. This piston O-ring excursion is relative to the volume scale on the outside of the cylinder wall. Volume change is accomplished while the Ventilator is running by turning “volume” knob in the desired direction. SETTING RATE Adjust the “Rate” control until the desired rate appears on the LED display.
KDS35 Small Animal Ventilator Cleaning & Maintenance CLEANING To clean the exterior surfaces, use a lint-free cloth to remove loose dust. Use care to avoid scratching the clear display window. For more efficient cleaning, use a soft cloth dampened with water or an aqueous solution of 75% isopropyl alcohol. MAINTENANCE No special maintenance is required other than periodic lubrication of the piston O-rings and the slide valve with the special non-toxic grease provided.
KDS35 Small Animal Ventilator Changing Piston and Cylinder This Ventilator is furnished with a 5 cc piston and cylinder installed. A 30 cc cylinder and piston is also supplied for users that require larger tidal volumes. NOTE: It is extremely important when changing piston and cylinders that they be aligned to be concentric and in line with the piston shaft.
KDS35 Small Animal Ventilator Changing Piston and Cylinder (continued) TO REMOVE THE CYLINDER AND PISTON 1) Set the Ventilator volume to maximum. 2) Run Ventilator at lowest speed and stop when the helical coupling is exposed. 3) Using a 0.050 Allen wrench (provided), disconnect the white piston from the coupling, leaving the coupling on the piston shaft. 4) Remove the two screws located in the front of the slide valve. 5) Remove piston and cylinder.
