DS7A/AH & PSARP  Peripheral Stimulators

DS7A & DS7AH High Voltage Constant Current Stimulators
	The DS7A provides up to 100mA constant current high voltage pulses of brief duration for percutaneous stimulation during investigation of the electrical activity of nerve and muscle tissue. The output current is continuously variable over the range 0 to 100mA. The DS7AH allows currents up to 1A with a maximum pulse duration limit of 200µs. This model is offered to overcome the difficulties of stimulating deep peripheral nerves, or large muscles such as the quadriceps with large area electrodes.  The DS7A or DS7AH can be triggered by an external device such as our new DG2A Train/Delay Generator.  For applications that require a higher output, we recommend our D185 MultiPulse (see below).  The DS7A & DS7AH are CE approved medical devices and have been cleared by the FDA for marketing within the USA. DS7AH (1A) DS7A (100mA
Major Features Include: - Pulse durations from 50 microseconds to 2 milliseconds. - 100mA (DS7A) or 1A (DS7AH) constant current output from 400V. - Flexible TTL compatible trigger options or front panel push button. - Output connection accessories, including plugs and cables are also available. - Optional Special Modifications include:  Alternating Polarity Option (M288A)
DS7A PSARP Muscle Locating Stimulator
	The Digitimer DS7A PSARP Muscle Stimulator is a variant of our popular DS7A Constant Current Stimulator (see above), which is both FDA cleared and MDD CE certified. It has been specially designed to meet the requirements of paediatric surgeons who need a reliable and easy to use muscle locating stimulator when carrying out the Peña, "Pull-through" or PSARP anorectal reconstruction technique.
Major Features Include: - 50Hz fixed pulse frequency. - 0-100mA constant current output from 100V compliance. - Two pulse durations (200us or 500us). - Compatible with re-useable and disposable bipolar stimulation probes - also available from Digitimer. - Optional footswitch (D185-FS1) for hands free control of stimulation.
