Earplug type auricular point electrode stimulation device

The invention discloses an earplug type auricular point electrical stimulation device. The earplug type auricular point electrical stimulation device comprises an earplug model, a plurality of stimulating electrodes, a multi-channel cable suite and a multi-channel stimulator, wherein the earplug model is placed in the auricle of a human external ear and used for fixing the stimulating electrodes and the multi-channel cable suite, the stimulating electrodes are embedded into the earplug model and used for stimulating different auricular points of the human ear, one end of the multi-channel cable suite is electrically connected with the plurality of stimulating electrodes, the other end of the multi-channel cable suite is electrically connected with the multi-channel stimulator, and the multi-channel stimulator is adjusted according to requirements to perform electrical stimulation on a single auricular point. The earplug type auricular point electrical stimulation device aims to help diabetic patients, hypertensive patients or other auricular point controllable organ disease patients to perform auricular point electrical stimulation treatment without being limited by time and places after guidance of doctors. Individual customization enables the earplugs to be accurately attached to auricle acupoints, and multi-channel electrode stimulation facilitates design of different stimulation treatment schemes.

External auditory canal imbedded cochlea blood oxygen saturation detector

The invention relates to a cochlea blood oxygen saturation detector with an embedded external auditory canal. The end part of the elastic earplug is provided with a through hole; the first and second reflective sensor probes and the photodiode in the elastic earplug face the through hole; wherein the first controller controls red light of the first reflective sensor probe and infrared light of the second reflective sensor probe to emit light waves to a middle ear indoor cochlea bottom ring according to time points, and PPG light waves reflected back by arterial blood are collected and subjected to photoelectric signal conversion through the photodiode and signal amplification and signal filtering are conducted on the converted PPG electric signal to obtain a PPG standard signal; meanwhile, the second controller obtains red light absorption coefficients of HbO2 and Hb in the arterial blood when the incident light is red light based on the first red light PPG standard signal and the second red light PPG standard signal, obtains infrared light absorption coefficients of HbO2 and Hb in the arterial blood when the incident light is infrared light based on the first infrared light PPG standard signal and the second infrared light PPG standard signal, thereby calculating the oxyhemoglobin saturation value.

Earplug type alarm clock based on bone conduction and implementation method thereof

The invention discloses an earplug type alarm clock based on bone conduction. The earplug type alarm clock comprises an earplug shaft piece. One end of the earplug shaft piece is used for plugging anear, and the front end of the earplug shaft piece is connected with an earplug head. The earplug type alarm clock further comprises an earplug sleeve which can slide in the axial direction of the earplug shaft piece, a sliding block which is installed on the earplug sleeve and used for impacting the earplug head, and a driving device which is installed on the earplug sleeve and used for driving the earplug sleeve to slide or vibrate. During work, the sliding block moves in the axis direction of the earplug shaft piece; if the earplug sleeve bears small resistance in the axial direction, the sliding block reciprocates in the axis direction; the earplug is subjected to large resistance in the axial direction, and a microcontroller controls the earplug sleeve to vibrate automatically, so thatvibration is transmitted to the brain of a user through bone conduction, and the user is awakened. The earplug type alarm clock is compact in structure and closely combined with ears. The auditory system of the user is isolated from the outside, so that work and rest are free of interference, and other people are not affected. A traditional alarm clock and noise reduction earplugs can be replaced. The earplug type alarm clock is good in effect and high in efficiency.

A kind of earphone earplug and preparation method thereof

The invention provides an earphone earplug, comprising an earplug body, the earplug body is an antibacterial silicone earplug, the antibacterial silicone earplug is made of antibacterial silicone, and the antibacterial silicone contains an antibacterial agent finished product, and the antibacterial silicone includes an antibacterial silicone by weight percentage 0.04wt%~6wt% of the finished antibacterial agent, the finished antibacterial agent includes a nano antibacterial agent and a porous antibacterial agent carrier, and the antibacterial silica gel includes 0.03wt%~1.8wt% of the nano antibacterial agent by weight percentage; The finished product contains a porous antibacterial agent carrier with an ultra-high specific surface area, which is conducive to the dispersion of the effective components of the antibacterial agent and greatly increases the surface contact of the antibacterial agent, improves the utilization rate of the inner surface of the antibacterial agent, and greatly reduces the addition ratio of the antibacterial agent; The added amount of antibacterial agent is low, which solves the problem that a high proportion of antibacterial agent added will affect the original performance of silica gel, and avoids the occurrence of adverse hidden dangers such as mechanical properties of antibacterial earplugs and skin-friendly comfort.
