Hand‑held telemedicine unit that takes photos and docks interchangeable exam tools

A portable diagnosis control unit (DCU) that holds a camera module and accepts a detachable front‑end attachment which can carry either the camera or a variety of medical diagnostic devices (stethoscope, dermatoscope, etc.). The DCU has trigger buttons, a microcontroller that detects which attachment/device is mounted, and a connector at the rear to link a local app (medical diagnostic examination system) on a user device for remote viewing and control. Intended users are clinicians or caregivers performing remote exams or first responders in the field.

(57) What the patent covered

The main independent claim covered a method using a hand‑held DCU that: communicates with local examination software via a rear connector, accepts a front attachment unit that holds a camera or interchangeable medical diagnostic devices in a receptacle, has a microcontroller that detects the mounted image capture device and the type of medical diagnostic device, and responds to trigger elements to operate the camera module and/or the attached medical device while transmitting captured diagnostic image/data to the local application for remote diagnostics.

The distinctive part: The system ties detection of interchangeable front attachments to trigger controls and direct connectivity to a local app through a rear connector for coordinated image capture and data transmission to remote exam workflows.

Novelty 3/5. Combines familiar parts, hand‑held camera modules, detachable probes (stethoscopes/dermatoscopes), and local telemedicine apps, but the claimed link among automatic attachment detection, trigger mapping, and a specific DCU connector was a clever integration rather than a wholly new category of product.

Making it

Injection‑molded plastic body, pressed or machined metal inserts for the attachment slot, off‑the‑shelf CMOS camera/cartridge assembly, PCB with microcontroller and connectors, final assembly and testing with hand insertion of camera and attachment parts.

Materials: ABS or PC injection‑molded plastics for the DCU housing, aluminum or stamped steel for structural mounts/clips, CMOS camera module (glass/plastic lens, image sensor), silicone or TPU for user grips/seals

Manufacturability 4/5. Several common subassemblies (molded housing, electronics PCB, camera module, interchangeable attachments) and manual assembly to fit the camera into the receptacle and test electronics; no exotic manufacturing but requires moderate assembly and calibration.

Is anyone buying?

We haven't run a demand check on this one yet. Shoppers would likely search for telemedicine handheld camera attachment, portable diagnostic camera with stethoscope dock, dermatoscope camera unit for remote exams; the links on the right open those searches.

Who buys it: clinics, telemedicine providers, emergency responders

Before you make it

We didn't find any related continuation or divisional patents still in force, although that doesn't rule out design patents, trademarks or unrelated patents covering the same product.

Practical issues include regulatory compliance (medical device classification and data privacy), image/video bandwidth limits, and a crowded market of modular telemedicine peripherals rather than any single dominant patented mechanism.

Owners occasionally revive lapsed patents (about 1.5% are), and this page is a research lead rather than legal advice, so get a freedom-to-operate opinion before you manufacture anything.

Claim 1, as granted

1. A method for facilitating medical imaging and remote diagnostic examinations, said method comprising: configuring a hand-held multipurpose diagnostic examination apparatus comprising a diagnosis control unit to communicate with a medical diagnostic examination system, wherein said medical diagnostic examination system is configured as a software application on a local user device, wherein said medical diagnostic examination system is accessible to said multipurpose diagnostic examination apparatus via a connector interface configured at a rear section of said diagnosis control unit, wherein said diagnosis control unit comprises a microcontroller in operable communication with a plurality of trigger elements positioned on a predefined section of said diagnosis control unit; mounting an attachment unit to a connector slot configured at a front end of said diagnosis control unit, wherein said attachment unit comprises a receptacle, wherein an image capture device is mounted to a camera module positioned at a front section of said diagnosis control unit and supported within said receptacle of said attachment unit, and wherein said attachment unit is configured to mount one of a plurality of medical diagnostic devices interchangeably to said diagnosis control unit; detecting said image capture device and type of said one of said medical diagnostic devices mounted on said diagnosis control unit, by said microcontroller; receiving actuation signals from one or more of said trigger elements positioned on a predefined section of said diagnosis control unit, by said microcontroller; processing said received actuation signals, by said microcontroller, to generate action control signals configured to indicate one or more actions to be performed by said image capture device and said one of said medical diagnostic devices; processing diagnostic image data captured by said image capture device, by said camera module of said diagnosis control unit; and facilitating transmission of said processed diagnostic image data from said camera module and diagnostic examination data of a plurality of formats from said one of said medical diagnostic devices, by said microcontroller, to said medical diagnostic examination system, wherein said connector interface is in communication with said camera module and said one of said medical diagnostic devices via said attachment unit to receive and transmit said processed diagnostic image data and said diagnostic examination data to said medical diagnostic examination system, and wherein said medical diagnostic examination system on said local user device is in communication with a remote user device over a communication network to facilitate remote viewing, remote selection, and said remote diagnostic examinations of a plurality of anatomical examination areas of a patient via said communication network.
