An Otoscope review new is a tool routinely used by audiologists in the clinical environment and represents a standard investment many clinicians personally pursue. While every otoscope is designed to provide illuminated magnification of the ear canal and tympanic membrane, the quality level produced by a particular otoscope and associated functionality is influenced by the technology one chooses.
At the end of the day, the specific type or model of otoscope is a matter of personal preference although the purchase decision is too often biased by how much an individual wants (or is not willing) to pay. In the same spirit of the mechanic who tells customers to spend the money and invest in good tires, the message with otoscopes is the same: spend whatever money is necessary to invest in the one (or two) otoscope(s) needed to accurately perform otoscopy.
With so many different options available, narrow down the product search by asking yourself three basic questions. This approach eliminates wasting time researching products that do not meet personal preferences and/or functional criteria. The following assumes the primary function of the otoscope is to perform otoscopy, leaving secondary applications (i.e. cerumen management, pneumatic otoscopy) out of the equation.
First, ask yourself whether there is a need or desire to capture images/video and/or project images/video on a larger screen. Technically, this is a two-part question but both are so similar it qualifies as one question. The image/video capture feature offers objective documentation of ear canal and tympanic membrane integrity in real time and useful in qualifying status prior to and immediately following clinical procedures such as cerumen removal or earmold impression techniques.
It also enables image/video sharing for educational or consulting purposes. Projecting images on a bigger screen (e.g., computer monitor, TV) offers the advantage of observing structures on a larger scale, offering a more detailed view of subtle structures. If these features are deemed unnecessary, the scope of your search should shift towards full-size head and handle otoscope combinations and pocket otoscopes. Conversely, if image capture and/or larger image projection functionality represent necessary features, Otoscope review video otoscopes should be the focus of your search.
Capacity refers to the amount of power the battery contains. This translates to how long the battery will last per charge. Both NiMH and Li-ion batteries maintain higher capacities than NiCad batteries, resulting in increased run time. In other words, otoscopes utilizing NiMH or Li-ion batteries will last about 30–50% longer before recharging is necessary.
The benefit of increased capacity is not accompanied by additional bulk with both weighing about one-third as much as the NiCad rechargeable battery.
Furthermore, Li-ion batteries Otoscope review have the slowest discharge rate and will not only retain a charge about twice as long as the NiCad or NiMH, but will maintain most of their charge even if when idle for several months. In contrast, the Ni-Cad and NiMH lose anywhere from 1 to 5% of their charge per day respectively even if the battery is not actually being used.
Memory effect refers to the inability for a rechargeable battery to remember how much reserve capacity is left immediately prior to recharging. In other words, initiating the recharging process prior to the battery being fully depleted can cause the battery to only remember the shortened cycle.
As such, the battery will not last as long between charging cycles. NiCad batteries are prone to this memory effect whereas the other two batteries are not. It is for this and previously mentioned drawbacks that otoscope components utilizing NiCad batteries will be significantly less expensive than similar components using Li-ion battery technology.
