MAQUET Power LED 500/500
Q: We have a satellite boom arm that continues to move slightly when it is put into required working position. How is this corrected?
A: More than likely a friction brake needs tightening or replacing. Check the horizontal arm for a flat head where the spring arm meets it, or perhaps a #4 mm Alan.
A: Is there a “release” button on the handle for when you position the boom? If so, it probably has pneumatic brake bladders that are not working for some reason. Could be low supply pressure, a kinked line or ruptured bladder. If the mount is not level or strong enough to remain rigid when articulated, equipment booms can drift regardless of what style brakes they have – friction or pneumatic. Friction brakes frequently wear out prematurely due to them being over tightened to compensate for poor celling mounts.
A: If it only moves slightly, I’d say friction. If it was air related or electric, those two are typically go or no-go.
A: In this picture [online] (tinyurl.com/tvbx9hd), the lower six dots you can see on the hubs of the four suspension arms are the brake adjustment screws, there are two for each rotation point on each arm. Some will be behind plastic covers, such as lighthead and yolk. These brakes are for rotation points, elevation drift has to be addressed by adjusting spring tension in the spring arm. You should remove the brake screws and inspect the pad. Just like auto brakes, once the wear portion is gone, replace the brake.
Hill-Rom Totalcare P1900
Q: I have Hill-Rom Totalcare and am moving. How can I disassemble the bed from the frame to be able to get it through a door and down some stairs?
A: I believe we’ve been through this recently. It depends on how skilled you are. Medical devices, including hospital beds, are not designed nor built to be easily disassembled and reassembled. The first question would be: Are you sure the floor in the room where you wish to use this device can support the bed? It weighs a lot more than a normal bed. The second question is; Do you own the bed or is it a rental? You’re going to need a few people to haul this bed through the doorway and up to the room you want it in. I can’t give you exact instructions on how to do this, just general and am in no way accepting any liability for what you do. Raise the bed to max height to get access and maximum visibility, unplug from wall. Removed base covers and disconnect batteries if it has any. Engage each function to help drain any power form caps and such. Label each cable and it’s connection before disconnecting. Disconnect any cable connecting the top half to the bottom half. Find a way to support the top half, then disconnect any hardware joining the two halves. Now you can separate the two halves. This should be enough to get the unit through the doorways.
A: This bed has hydraulics for all of the mechanisms, so if you are not familiar with hydraulic systems I would advise against taking it apart.
Philips Respironics V60
Q: I have a V60 ventilator that will not pass test 5 air flow and test 6 oxygen flow. Both are constantly >20 SLPM below passing specs.
A: Did you have the red flag in? Sometimes that flag is loose and you can bypass that by clamping off the exhaust tube with hemostats. If replacing the gas delivery system didn’t fix it, it seems like a leak in test equipment. Either that or the white clamps are loose that connect the GDS to the gas outlet.
A: Have you tried the flow sensor assembly?
