Device inputs include user-selected settings via a touch-sensitive glass front panel; it outputs monophasic, rectangular, decaying electrical waveforms (300-600 µA, 100 Hz) to the body through four adhesive skin electrodes. Designed for handheld use, the device is powered by four internal AA batteries and operates for preset durations of 30 or 60 minutes. It features status LEDs for power, low battery, output set-points, and countdown timers. The device is intended for symptomatic pain relief, helping patients manage chronic, post-traumatic, or post-surgical pain conditions. ## Clinical Evidence No clinical testing was submitted. Substantial equivalence was demonstrated through non-clinical bench testing, including enclosure materials testing, battery life, device extended use reliability, firmware functional performance, and connection testing. ## Technological Characteristics Microcurrent TENS device; ABS plastic housing with touch-sensitive opaque glass front panel; FR4-based current generator (0-33V DC, 400µA, 100Hz); monophasic rectangular waveform with decay; battery-powered (4x AA); dimensions 190x80x30mm; weight 350g; uses external adhesive electrodes. ## Regulatory Identification A transcutaneous electrical nerve stimulator for pain relief is a device used to apply an electrical current to electrodes on a patient's skin to treat pain. ## Predicate Devices - Alpha Stim ([K896948](/device/K896948.md), [K881753](/device/K881753.md), [K831145](/device/K831145.md), [K831144](/device/K831144.md)) - BioMedical Life Systems, Electro-nerve stimulator TENS model micro plus-A ([K915210](/device/K915210.md)) - Lhasa Oms Inc, E Stim II ([K050435](/device/K050435.md)) - Fuji Dynamics Ltd, Medisana Digital Tens ([K994265](/device/K994265.md)) - Globalcare Intl., Inc, Globalcare Micro II and Microcare (TENS) ([K903394](/device/K903394.md)) ## Reference Devices - Top-Rank Healthcare Equipment Co Ltd Adhesive Electrode ([K070612](/device/K070612.md)) - Sekisui Plastic Co Ltd Technogel ([K070612](/device/K070612.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The Kingfisher Healthcare NV KFH Energy model E1 differs from some of the above products in that it is a dedicated microcurrent device and does not have a high-current mode. The Kingfisher Healthcare NV KFH Energy model E1 is made of the same types of material as the products referenced above. The front display of the Kingfisher Healthcare NV KFH Energy model E1 differs from the predicates in that it is made of a "wipc-clean" glass surface eliminating any possibility for contamination to build up around indicators or controls. # Patient Contact Patient contact with the main device is limited to finger operation of the controls and made only with glass front panel or ABS casing (when held in the hand). Connection to the patient is made by electrodes which are already legally marketed: | Electrodes: | Top-Rank Healthcare Equipment Co Ltd Adhesive Electrode | |-------------|----------------------------------------------------------------| | | K070612 | | Gel: | Sekisui Plastic Co Ltd Technogel, included in electrodes above | | | K070612 | # Description of Product: The Kingfisher Healthcare NV KFH Energy model E1 is built in an ABS casing with controls and indicator integrated into a touch-sensitive opaque glass front panel, and designed to be comfortably held in the hand. The approximate dimensions of the unit are 190 x 80 x 30 mm and complete with batteries the unit weighs approximately 350 g (including batteries). The device is designed to deliver electric current in the range 300 to 600 microamperes at 100 Hz frequency to the body from four "AA" sized batteries (contained internally), for a predctermined time (30 or 60 minutes), through four adhesive skin electrodes (already found substantially equivalent through the 510(k) process). The output waveform is monophasic, rectangular with decay. {3}------------------------------------------------ Image /page/3/Picture/1 description: The image shows the logo for King Fisher Healthcare. The logo includes the company name in a simple, sans-serif font, with the words "King Fisher" stacked on top of "Healthcare". To the left of the text is a stylized graphic, possibly representing a bird or a leaf. Below the company name is the tagline "Journey for life" in a smaller, italicized font. # Housing The ABS plastic housing is comprised of three parts: - . upper housing - lower housing, and . - battery compartment cover . The battery compartment cover is a clip fit to the lower housing, secured with a screw, which is sealed to the upper housing with a rubber gasket and retained in position by four screws. Two clectrical connectors are located in the housing, identified as C1 (channel 1) and C2 (channel 2), for connection of the four patient contacting electrodes. # Glass Front Panel The front glass panel is opaque and sealed to the upper housing by a self-adhesive gasket. Electrical circuitry is integrated into the rear of the glass panel allowing the front face to act as a "touch-sensitive" user interface. Two depressions are milled into the front face of the glass front panel to assist locating the fingers over the control areas: - a circular depression over the on/off control . - a "ring" shaped depression over the output control area. The two sides of the . "ring" can be used to independently control the two output channels. The elcctrical circuitry also contains the status indication light emitting diodes which can be seen through the glass panel: - . power on - low battery warning . - an output set-point indicator for each channel . - six "count-down" timer indicators ( 10, 20, 30, 40, 50 and 60 min.) . # Controller Board A controller board is located between the upper and lower housings. This is the FR4 based current generator rated at: 0 - 33 v d.c., 400 µA, 100 Hz. The Kingfisher Healthcare NV KFH Energy model E1 will be packaged in a presentation cardboard case together with electrodes, leads, batteries, storage bag and the user manual. The KFH Energy device is indicated for the symptomatic relief of: - Chronic Intractable Pain . - Post-Traumatic Pain . 510(k) Summary Section 1 {4}------------------------------------------------ K073008 KFH Response to Email of S.
