There are many instances in which backup power source for devices at a hospital or health facility might be needed. Say there is a blackout. Or there is a need for extra devices to be set up because the facility is past capacity. Battery packs for medical equipment then come in handy to help save lives. They become the saving grace in emergency situations. More so in remote areas and war zones.
How about a quick look at some of the common types? The first is Zinc air. This is not quite the standard option in medicine but it has been known to make an appearance. Many many years ago legislation banned the mercury zinc oxide cell. This has been found to be a suitable replacement for that. It has a short shelf and charges life but it has been found to be very affordable. The mechanism of action is oxidation of the zinc with O2 in the air.
Another type is Lithium iodide. This is considered to be the standard cell in medicine. It uses lithium as an anode and has a long charge life. That makes it quite suitable for devices such as the pacemaker. It can be used for up to 15 years without requiring replacement. It may also be quite expensive. Another type is the NiCad. This is fading out though and is only used in rare occasions where necessary. However, new and modern options are being discovered.
One of the key components of cells and their suitability for any device is the chemistry. The chemistry determines whether the cells will run that device efficiently. Chemistry will also determine how long it will stay in use. The chemistry might also compromise the device itself. That is if it is not appropriately analyzed. One aspect of chemistry is the internal resistance. This is a phenomenon that causes the cell to heat up excessively and causing a drop in voltage, therefore, causing a shortcoming in functionality.
Without a bit of tweaking, a cell will not be working at its best in very high ambient temperatures. Over time the cell structure will break down. In general, the cell will not give as much service as it would have an optimum temperature. In the short term, the contrary will be perceived. Optimum temperature is considered to be room temperature.
Does everyone like a cell that charges quickly, right? This is not a good thing, while convenient, it is not good for the long-term wellness and functionality of the cell. This is due to the chemical and physical changes brought about by fast charging. This degradation might also affect the structure of a device.
As a layman, one will usually be interested in one thing. The charge life. How long will the charge keep? How long will the device run on the cell only? Is it long enough? Is there some sort of mechanism that allows for a backup cell to be attached?
Whatever cells must be manually charged should be kept fully charged at all times. Life in medicine is very unpredictable. The cells should be on standby at any time. There should also be as many extras as possible. Just keep an eye on the shelf life.
