Background
The Medical Microlab Spirometer is the Model 3300 Version 043-12 that was released in 1998.
This device page is necessary for making repairs on a spirometer, which is used for measuring respiratory flow rates in patients, especially those with chronic obstructive pulmonary disease (otherwise known as COPD). Because this is a piece of medical equipment, it is critical that this device properly works without faults, and if it were to have complications, it is important to know how to fix it. The information provided is directed towards biomedical technicians and pulmonologists who oversee the maintenance of medical tools and equipment.
This specific device is battery-powered, and the batteries can be recharged. It can be customized to perform different types of tests. For example: when performing a relaxed vital capacity test, the operator of the machine must have a patient breathe into this device, and the results will display on the screen in the form of a flow/volume curve. More detailed information regarding the different types of tests that can be performed with this device can be found in the operating manual.
This is not the most recent model of this device, with newer models operating more commonly than this one. However, it is not extinct yet, and this page can provide any owner of the 1998 Medical Microlab Model 3300 Version 043-12 with the resources to resolve any issues with the device.
