In-vitro test stimulator

Abstract

The invention discloses an in-vitro test stimulator, and belongs to the technical field of implanted medical instruments. The in-vitro test stimulator is mainly used for nervous electric stimulation therapy test. The double-channel pulse output in-vitro test stimulator with a user interface can output accurate parameter adjustable electrical stimulation pulse, and is used for treatment test or short-term electric stimulation therapy experience of patients in implanted nerve stimulator operation. The test stimulator is characterized in that the test stimulator adopts integrated structural design, and mainly comprises a shell, a toggle switch, a film key, a display screen, a battery, a printed circuit board and the like. The test stimulator is small and simple; through the key and the switch, pulse parameters and test electrode load impedance can be adjusted and the polarity of an electrode contact can be set, so the test stimulator is intuitive and convenient to operate; and through the design of self-locking function and error operation prevention, error operation of the patients in use can be effectively prevented, and the test stimulator is safe and reliable. The test stimulator can be widely applied to test assessment and experience of electric stimulation therapy.

Description

Technical field [0001] The invention is an in vitro test stimulator used by doctors or patients for testing and evaluation during implanted electrical stimulation therapy operations, and belongs to the technical field of implanted medical instruments. Background technique [0002] At present, implantable electrical stimulation systems have been widely used in the treatment of neurological diseases. For example, deep brain stimulation devices (brain pacemakers) are often used to treat movement disorders such as Parkinson’s disease. Spinal cord stimulators can effectively improve chronic diseases. Pain, wait. The composition of an implantable electrical stimulation system generally includes an implantable pulse generator, one or more electrodes, and an extension wire connecting the pulse generator and the electrodes. Among them, the pulse generator is the core part of the system, which is used to generate electrical stimulation pulses with specific waveforms with adjustable parame...

AI Technical Summary

Problems solved by technology

[0004] If the implanted pulse generator is directly used for testing, the main problem is that the cost is too high

The pulse generator is a one-time-use sterile medical device. Once the sterile package is opened, the patient needs to pay more than 100,000 yuan for the purchase. If the curative effect is not satisfied, it will form a huge waste

In addition, setting the parameters of the pulse generator requires the remote control of the external program controller, which causes inconvenience for doctors and patients in operation, and it is impossible to intuitively read the working status and pulse parameters of the pulse generator

The medical pulse generators available on the market are often relatively large in size, which is not easy for patients to carry and affects the free activities of patients. The pulse waveform, parameters and accuracy of their output may not meet the needs of clinical use.
