Lithium Batteries in Medical Equipment
Factors such as the aging of the global population, the improvement of people’s living standards, and the increase in demand for medical services in remote areas are prompting the transformation of traditional medical methods. Mobility and portability have gradually become keys to affect the medical electronics industry. On the other hand, the development of semiconductor technology has promoted the pace of medical innovation to move forward at an unprecedented speed. Driven by high-precision analog-to-digital conversion and advances in wireless network technology, medical electronic products have become portable and miniaturized. Because of this, lithium batteries for medical equipment have become one of the hot products.Medical equipment has become an important field of modern medical care. Compared with other traditional technologies, lithium batteries have many advantages in the application of portable medical devices. This includes higher energy density, lighter weight, longer cycle life, better battery capacity retention characteristics, and a wider applicable temperature range. Lithium batteries for medical equipment mainly have the following characteristics in medical equipment.
:) Good Safety.
The structure is made of aluminum-plastic flexible packaging, which is different from the metal shell of a liquid lithium battery. In the presence of safety hazards, liquid batteries are easy to explode, while medical equipment batteries are only bulging at most.
:) The Thickness is Small and it can be Thinner.
There is a technical bottleneck for liquid lithium-ion batteries with a thickness of less than 3.6mm, but there is no technical bottleneck for medical device batteries with a thickness of less than 1 mm.
:) Light Weight.
Lithium batteries for medical equipment are 40% lighter than steel-shell lithium batteries of the same capacity and they are 20% lighter than aluminum-shell batteries.
:) The Shape can be Customized.
The lithium battery of medical instruments can increase or decrease the thickness of the battery according to customer needs, and the shape can be changed flexibly and quickly.
:) Large-capacity.
Lithium batteries for medical instruments are 10-15% higher than steel-shell batteries of the same size, and 5-10% higher than aluminum-shell batteries.
:) Small Internal Resistance
Through special design, the impedance of the lithium battery is greatly reduced and the high-current discharge performance of the lithium battery is improved.
1. Good safety factor.
Most of the lithium batteries used in medical equipment batteries are aluminum-plastic film soft-packed lithium batteries, which are different from the metal shell of liquid batteries. If there is a safety accident, the liquid battery is very prone to explosion, and the medical equipment battery will only bulge at most. Pack.
2. The thickness of the soft-packed lithium battery is small.
It can achieve a thinness of 0. 5mm, and at the same time can withstand certain bending or distortion conditions without affecting battery performance. There is a technical bottleneck in the thickness of liquid lithium-ion batteries below 3.6mm.
3. The weight is relatively light.
Medical equipment batteries use soft-packed lithium batteries, which are 40% lighter in weight than steel-shell lithium batteries of the same capacity and 20% lighter than aluminum-shell batteries. They are very suitable for portable medical equipment and personal care equipment.
4. The shape of the soft-packed lithium battery can be customized at a high end.
According to customer needs, the thickness of the battery can be increased or decreased or the shape can be changed to improve the performance of the actual use function of medical equipment.
5. High capacity of soft-packed lithium battery.
Compared with steel-shell batteries of the same size and specifications, the capacity of soft-packed lithium batteries is 10-15% higher, and 5-10% higher than aluminum-shell batteries.
6. Laminated processing to improve performance.
Soft-packed lithium batteries are manufactured using laminated processing technology. According to the special design, the impedance of the battery can be greatly reduced and the performance of the battery's high-current discharge can be greatly improved.
Which medical equipment are lithium batteries mainly used in?
Mainly used in hearing aids, electronic stethoscopes, mobile ECG monitors, infusion pumps, ventilators, anesthesia machines, light curing machines, physical therapy, rehabilitation equipment, portable X-ray film machines, blood glucose meters, infusion detectors, orthopedic fixation devices, thermometers, defibrillators, wheelchairs, external pacemakers, blood routine analyzer, electrocardiogram, root canal treatment instrument, ventilator, monitor, medical beauty and massage fitness equipment, etc.
Battery is the key resource to support medical equipment to work. It is dangerous for patients when they are in ttreating but medical equipment are out of power or broken, thus how to prolong lithium battery life is very important for medical equipment users to know. Here are some tips for you to maintenance lithium batteries in medical equipment.
Tip 1: It is strictly forbidden to store powerless batteries.
It is strictly forbidden for the battery to be in a state of power loss when it is stored. The power loss state refers to the failure of the battery to be charged in time after use. Storing the battery in a state of power loss, it is easy for the battery to self-hibernate and protect from low power, resulting in insufficient charging and a decrease in battery capacity. The longer the idle time in the power-loss state, the heavier the battery damage. It will directly cause the battery to fail to be charged. Therefore, when the battery is idle and not in use, it should be recharged once a month to better maintain the healthy state of the battery.
Tip 2: Regular Inspection.
During use, if the use time of the machine suddenly drops in a short period of time, it may be that the battery capacity is insufficient or it is not really fully charged. At this time, you should go to a professional repair agency in time to inspect and repair the machine and battery. This can relatively extend the life of the battery pack and save money to the greatest extent.
Tip 3: Correctly grasp the charging time.
During use, the charging time should be accurately grasped according to the actual situation, refer to the usual frequency of use and instructions, and also pay attention to the capacity description provided by the battery manufacturer, as well as the performance of the supporting charger, the size of the charging current and other parameters to grasp the charging frequency. Under normal circumstances, the battery is charged at night, and the average charging time is about 8 hours. If it is lightly discharged (the battery is used for a short time after charging), the battery will be fully charged soon, and overcharge will occur if it continues to be charged, causing the battery to bulge and heat up, reducing battery life. Therefore, it is best to charge the battery once when the machine prompts that it needs electricity, and make the necessary charging according to the actual situation to avoid harmful charging.
Tip 4: Prevent exposure, short circuit, and high temperature.
Batteries are strictly prohibited from being exposed to sunlight. An environment with too high temperature will increase the internal pressure of the battery and force the battery pressure limiting valve to open automatically. The direct consequence is to increase the explosion of the battery, and excessive water loss of the battery will inevitably cause the battery activity to decrease, accelerate the softening of the plate, and the housing will heat up when charging. Fatal damage such as bulging and deformation of the housing. A short-circuited battery will catch fire and directly burn the machine and battery or cause a greater disaster!
Tip 5: Avoid the plug heating up when charging.
Phenomena such as loosening of the charger output plug and oxidation of the contact surface will cause the charging plug to heat up. Too long heating time will cause the charging plug to short circuit, which directly damages the charger and causes unnecessary losses. Therefore, when the above situation is found, the oxide should be removed or the connector should be replaced in time.
