Portable applanation tonometer allows measurement of intraocular pressure in children, patients unable to cooperate for slit lamp exam, and in anesthetised patients.

Portable Bar Code Reader is battery operated and stores scanned or keyed data in its memory for later batch uploading to a computer. This is the perfect reader for physical inventory, receiving items into stock and remote scanning. The portable bar code reader provides a convenient and efficient way of collecting a large amount of bar code data while moving about away from the computer.

Portable binocular microscope is a compact device that is used in surgery to provide a clear view of small and inaccessible parts of the body. It is fitted with double eyepieces for vision with both eyes. The purpose in dividing the same image from a single objective of the usual compound microscope is to reduce eyestrain and muscular fatigue, which may result from monocular, high-power microscopy.

The portable defibrillator operates on rechargeable batteries and therefore make use of DC-DC converters for stepping up the voltage required for charging the storage capacitor. The maximum energy delivered by portable defibrillator is generally 300 ohm delivered into 50 ohm load which is equivalent to about 400 Ws of stored energy. Since the patient impedance can vary considerably, it has a strong effect on defibrillation effectiveness.
