Cooper-Rand electrolarynx is a device manufactured by American company Luminaud Inc. The device consists of two parts, a tone generator and a pulse generator. Both parts are connected with a cord. The device is powered by two 9V non-rechargeable batteries.[1]

Main Characteristics

Cooper-Rand elecrolarynx is a medical device which is shipped more than 20 years. It consists of two parts, a pulse generator which weights 212.6 grams and the tone generator which weights 28.35 grams. Only the tone generator is hold in a hand, thus users do not have to lift as heavy device as in the electrolarynges where the battery is included in a device.[1] This could be especially beneficial to patients who physical strength is limited due to illness as A.L.S., M.S or severe injury.[2]

It is an intra-oral device, which means that the plastic tube in the end has to be inserted in patient's mouth. This could be advantageous in the patients after surgery when the tissues are particularly sensible, since the device does not vibrate against throat tissue. The sound is delivered through plastic tube to the palate. Then, patient's tongue, jaw and lips articulate words.[2]

There are use two non-rechargeable batteries in the pulse generator of the device. It has to be replace each 4 or 6 weeks.[3]

The pulse generator is made by plastic which is covers by gold anodized aluminium.[1]

Purpose

This device is directed towards laryngectomy patients that lost their ability to produce speech. The usage of an electrolarynx allows them to communicate in a quick and natural manner without resorting to other means such as pen and paper.

The company does not inform about any other important dates that are relevant to this particular device. It, however, claims that the device is used over 20 years.[1]

Enhancement/Therapy/Treatment

Electrolarynges are meant to return the ability to communicate by voice for laryngectomy patients. Cooper-Rand is especially useful for patients with reduced strength, since the tone generator is particularly light.[2] In contrast, the speech of patients who use intra-oral electrolarynges as Cooper-Rand is, however, slower than the speech of patients who uses electrolarynges placed on their neck.[7]

Ethical & Health Issues

There are no ethical issues connected to this particular device.

From the point of view of health, there a greater risk of infection than in a case of devices which are placed on a neck.[7] Therefore, the sufficient hygiene is needed in dealing with this type of electrolarynx.
