Sensory nerve quantitative analysis instrument

sa — Sun, 03 Jul 2022 10:19:14 +0000

The automatic sensory nerve quantitative tester (Neurometer CPT/C) determines the conduction threshold (sNCT) of the tested sensory nerve by measuring the current sensory threshold (CPT) of the skin/mucosa. This is a fast and painless test method to objectively and comprehensively analyze and quantify the functions of thick myelinated, thin myelinated and unmyelinated sensory nerve fibers. The CPT/C detector is simple to operate and convenient to carry. The standardized double blind test is carried out by computer, which is very suitable for clinical and research use.
Clinical application of Neurometer CPT test in neurology:

Identify sensory nerve dysfunction
Determine the type, location and scope of sensory nerve dysfunction
Differential diagnosis of myelopathy, radiculopathy, mononeuropathy, polyneuropathy, compression neuropathy, focal neuropathy or peripheral nerve injury; Differentiation between axonal and demyelinating lesions
It can detect metabolic, toxic, hereditary, congenital, compressive, traumatic and other peripheral neuropathies as well as sensory damage of central nervous system diseases
Quantify the severity of sensory nerve dysfunction
Monitoring the progress of neuropathy/nerve injury
Help select treatment interventions
Monitoring the therapeutic effect and the recovery of neurological function
Pain assessment and management
Malingering

Myoelectric evoked potentiometer

sa — Sun, 03 Jul 2022 10:18:10 +0000

The Nicolet EDX EMG Evoked Potentiometer integrates the comprehensive advantages of existing EMG products, combines the most advanced electronic technology, and cooperates with world-renowned clinicians, technicians and researchers to develop a new generation of Nicolet EDX EMG Evoked Potentiometer. The system has powerful functions, simple and flexible operation, high quality data collection, and can fully meet the needs of different clinical applications.

Nicolet EDX is closely combined with clinical application and has rich software functions:

It has motor unit count (MUNE), conduction velocity distribution (CVD), inching and other special nerve conduction tests, which provide basis for the efficacy evaluation and prognosis of motor neuron disease, carpal tunnel syndrome and other diseases. Inching technology is the best diagnostic method for multifocal motor neuropathy
Quantitative electromyography (QDEMG), single fiber electromyography and other advanced electromyography tests provide more detection means and basis for the analysis of myopathy;
The tremor analysis software pioneered by Nikoli provides reliable analysis basis for the tremor symptoms of Parkinson’s disease patients, and provides a quantitative analysis method for the electromyography of Parkinson’s disease
The “three impulses” stimulation has solved the variation of MEP latency, amplitude and shape, and the shortcomings that MEP is sometimes difficult to record on the target muscle, providing a quantifiable way of motor cortex information and reproduction

Amplifier features:

? 2-8 channel arbitrary configuration
? 10-20 electrode placement diagram makes the operation of evoked potential items more intuitive and fast

Characteristics of electrical stimulation:

? Two electrical stimulation outputs
? New concept ergonomic handle stimulator
? Rich keys can adjust all parameters through the handle stimulator
? Flexible operation by crimping flexible cables

Cerebral Function Monitor

Founded in 1989, US Natus Neurology Incorporated is a leading manufacturer of medical equipment and software in the world. Its products cover disciplines such as neonatal monitoring, nervous system, sleep, hearing and balance. The company has many well-known brands, including Nicolet. Since 1965, it has provided clinical services in EEG, EMG, EP, IOM, ICU, Sleep, LTM, With different solutions and high-quality equipment and consumables in various fields such as TCD, the products are distributed in more than 100 countries around the world.
This equipment adopts the monitoring method of original EEG combined with quantitative or semi quantitative analysis, providing a professional, simple and practical powerful tool for clinical experts and ordinary medical staff to monitor the brain function of critical patients in real time.
At present, the monitoring of brain function has been paid more and more attention to in clinical practice at home and abroad. Continuous monitoring of brain function has become the monitoring standard for critical patients with neurological deficits abroad, which will also be a new trend in the development of domestic neurological monitoring. Brain function monitoring not only contributes to the early detection of diseases in clinical application, but also has important clinical significance in the adjustment of treatment plans and prediction of patient prognosis, Moreover, it has far-reaching significance for clinical research and teaching, and will greatly improve the level of medical treatment, teaching and research in the department.
The brain function monitor can provide early detection of neurological complications before the occurrence of clinical symptoms and signs of patients through early detection of abnormal changes in patients’ brain functions, guide clinical early intervention, avoid more serious injuries, and save the cost of rehabilitation of patients; Through convenient and continuous monitoring at the bedside, expensive imaging examinations are reduced and medical resources are saved; In the course of treatment, accurate drug management is carried out according to the patient’s condition to save medication; Shorten the stay time of patients in ICU and save costs. It has good economic and social benefits for patients and the hospital.
Brain function monitoring is recommended in the following cases:

Traumatic brain injury

A high proportion of patients with brain injury will often have epilepsy
The longer the epileptic activity lasts, the more difficult it is to treat, and the higher the mortality rate
Detection of subclinical epilepsy, evaluation of convulsions, and evaluation of treatment
Suspected neurological or systemic condition

Stroke

Early detection of vasospasm or secondary damage after stroke or cerebral vascular surgery
Via α Vasospasm was found in the early stage of variability

Surgical treatment

Carotid artery shunt surgery – check the brain condition during or after the clamping process
When cardiopulmonary bypass is used
Risk of cerebral embolism and stroke during surgery
Control the incidence of postoperative neurological complications (patient prognosis)
Brain function was monitored during operation

Cardiac arrest

Amplitude integrated EEG (aEEG) has predictive value for the prognosis of patients with cardiac arrest and CA treated with induced hypothermia
