A tympanic ventilation tube with screw locking, multiple waterproofing and valve control drainage functions

PendingCN122398536AExternal Auditory CanalsMedicine
The application discloses a tympanic ventilation tube with spiral locking, multiple waterproof and valve control drainage functions, and belongs to the field of ear implant medical devices. The ventilation tube comprises a tube body, an implant device interface is arranged at the outermost end of the tube body, a one-way duckbill valve is arranged at the end close to the external auditory canal, micro-flow ventilation holes are distributed in the circumferential direction of the side wall, a flexible sealing sheet is arranged on the outer side of the tube body, and a continuous single-ring gradually-changing asymmetric spiral fixing structure is arranged on the outer periphery of the middle ear cavity. The spiral fixing structure induces the radial flanging of the tympanic membrane tissue to be embedded between the spiral structure and the outer wall of the tube body to form axial locking through the asymmetric section, and realizes gradual release when reversely rotating through the rise angle, tooth height and round angle gradient; the sealing sheet realizes stable adhesion and controllable peeling through the thickness gradient, pre-stress and surface energy gradient; the micro-flow ventilation holes and the duckbill valve constitute a gas-liquid separation double channel, realize low-resistance ventilation, liquid blocking and pressure-driven drainage. The application can realize stable fixation, water-tight sealing, controllable ventilation, one-way drainage and low-damage implantation and removal.

An in-ear audio glasses temple and smart glasses

ActiveCN224317874UFunctionalGuaranteed normal playbackNon-optical adjunctsExternal Auditory CanalsSmartglasses
An in-ear audio glasses temple and smart glasses are disclosed. The in-ear audio glasses temple includes a temple body and an audio component. The temple body includes a temple arm, an ear hook, and an in-ear portion. The ear hook is mounted on the temple arm, and the in-ear portion is slidably mounted on the end of the temple arm and has a sound hole. The audio component is installed in the in-ear portion and corresponds to the sound hole. The first end of the temple arm is used to connect to the frame, and the ear hook can be suspended on the ear so that the in-ear portion installed on the end of the temple arm is aligned with the external auditory canal. Sliding the in-ear portion can drive the audio component in and out of the external auditory canal. The smart glasses include a frame with lenses and two sets of in-ear audio glasses temples. The two sets of in-ear audio glasses temples are symmetrically arranged on the left and right ends of the frame and are hinged to the frame by the temple arm. The two ear hooks are suspended on the ears to wear the smart glasses, and the two in-ear portions are slid into the external auditory canal so that the audio component plays sound in the external auditory canal, thereby improving the listening effect and ensuring privacy.

In-ear sign detection device and system

ActiveCN119184631BExternal Auditory CanalsMechanical engineering
The application relates to an in-ear type sign detection device and system, wherein the in-ear type sign detection device comprises an infrared temperature measurement assembly and a first mounting piece; the infrared temperature measurement assembly is mounted on one end of the first mounting piece close to an eardrum, and the first mounting piece is elastic; when the sign detection device is worn, the first mounting piece is in an external auditory canal of a wearer, and the first mounting piece is deformed elastically so that the infrared temperature measurement assembly is aligned with the eardrum of the wearer, and the infrared temperature measurement assembly is used for detecting the eardrum temperature of the wearer. The first mounting piece can adapt to different external auditory canal shapes, and then the wearer can adjust the in-ear angle of the first mounting piece, so that the infrared temperature measurement assembly can be aligned with the eardrum of the wearer. The problem that existing in-ear type temperature detection devices cannot accurately monitor the core temperature of the human body in some cases due to the fact that the individual differences of the external auditory canal shapes among different users are not considered is solved.

Non-invasive ICP detection and regulation system

ActiveCN121154125BExternal Auditory CanalsIntraocular pressure
The application discloses a noninvasive ICP detection and regulation system, comprising a transcranial Doppler monitoring module, an intraocular pressure sensing module, a tympanic membrane pressure monitoring module, an abdominal pressure regulation module, a data fusion processing module, an alarm module and a power management module. The monitoring modules respectively collect intracranial arterial blood flow velocity waveform, intraocular pressure pulsation and external auditory canal pressure fluctuation signals, and transmit the signals to the data fusion processing module for comprehensive analysis to generate an ICP evaluation result. When the evaluation value exceeds a preset range, the alarm module is triggered, and an instruction is sent to the abdominal pressure regulation module to adjust the abdominal pressure. The power management module supplies power to each module. The system improves detection accuracy through multi-signal fusion, forms a monitoring-regulation closed-loop mechanism, does not need manual operation, shortens response time and guarantees regulation consistency.
